Abstract: A chain saw bar nose has a rotatable sprocket. The sprocket assembly is adapted to conform in shape to the drive tang portions of the saw chain whereby the nose sprocket may receive operational forces imposed by the saw chain substantially as compressive forces as opposed to tensile forces. As a result, the nose sprocket assembly better withstands the harsh operating conditions imposed by cutting applications.

Abstract: A cylinder press converted to printing foil embossed images onto a printing stock. A supply roll of foil bearing ribbon is mounted forward on the reciprocating chase and the ribbon is extended over the chase through a pair of adjusting guide rollers to a stationary take-up mechanism. In the take-up mechanism, the ribbon is wrapped around a puller roller and onto a rewind roller. One of the guide rollers is stationary and the other reciprocates in a parallel path in at least half the speed of the reciprocating chase. The ribbon is wound in a serpentine configuration around the reciprocating guide roller forward to the stationary guide roller and back to the take-up mechanism to thereby retain a fixed pathway length regardless of the position of the chase. The ribbon is wrapped around the puller roller having a friction gripping surface for non-slip pulling of the ribbon.

Abstract: An integrated throttle control and idle validation sensor includes mechanically coupled but electrically independent throttle control and idle validation components. A single mechanical input to the protective sensor housing corresponds to an accelerator pedal position and causes selective coupling of a supply voltage to one of an idle validation conductor and a throttle validation conductor for interpretation by an electronic control system. The throttle control system within the sensor housing comprises a potentiometer adapted for movement corresponding to the mechanical input whereby a variable voltage throttle control signal may be delivered to the electronic fuel control system. The sensor integrates previous separate throttle control and idle validation functions into a single environmentally secure housing and requires no calibration. The disclosed throttle system is more reliable and less costly than previously available separate throttle control and idle validation functions.

Abstract: An electronic foot pedal for outputting an electrical signal proportional to the degree a treadle is pivoted. The electronic foot pedal has an improved spring arrangement for yieldably biasing the treadle toward its home position. Dual springs are provided, independently mounted and supplementary to each other. Each spring has an adequate biasing force to urge the treadle to its home position. The springs are of a ribbon-like material that are wound into a flat spiral. The springs are subjected mainly to bending forces and have flexure as the treadle is pivoted to its pivotal limits.

Abstract: A chain saw feed mechanism includes an arm pivotally mounted to the chain saw and carrying a dog for pivotally engaging the workpiece at the kerf. Thrusting the chain saw along the longitudinal axis of the guide bar moves the guide bar along an arc concentric to the point of workpiece engagement and thereby cuts laterally through the workpiece. Longitudinal thrusting force applied by the operator transfers via the lever arm into lateral feed force needed for cutting the workpiece. The feed mechanism is particularly useful in aggregate cutting applications, where the chain saw is heavy and large cutting forces are needed to pass the saw through the aggregate.

Abstract: A method and associated apparatus are shown for highly efficient manipulation of multiple pipe sections within the close confines of a tunnel formation to construct an underground conduit. Overall production is improved by adapting pipe section transport equipment to quickly deliver multiple pipe sections to a placement site and return immediately with the pipe carriages for a next load. Pipe section placement equipment is adapted to manipulate the pipe sections as delivered at the placement site, without any intermediate handling step, and position the pipe sections according to desired line and grade specifications.

Abstract: A saw chain having center links and side link pairs that are pivotally joined by a headless fastener. The side link pairs are formed into an integral unit, by a bridge portion to receive a center link therebetween. The center link and the side link pair have aligned bores for receiving a fastener. The fastener has a center section that is rotatably received in the bore of the center link and has larger end sections on each side of the center section that are received in the bores of the side link pair. The diameter of the center section of the fastener is smaller than the diameter of the end sections. The bore of the center link is of a smaller diameter than the bores in the side link pair. The fastener is forcibly inserted into the aligned bores of the side link pair and the center link. The forced insertion of the fastener forces the bore of the center link to enlarge permitting an end section of fastener to pass through with the center section of the fastener residing in the bore of the center link.

Abstract: A punching tool for producing weep holes in a sill can utilized for window installations is disclosed. The tool has pivotally mounted jaws operable by a handle assembly with a punch formed flush with an end of a first jaw and a die opening provided in an end of a opposed second jaw. The pivotal connection of the jaws maintains the punch and die opening in arcuate alignment as the jaws are pivoted. A throat of the tool receives the upstanding leg of the sill can with the formed punch fitting flush against the bottom of the sill can and thus the tool will produce a weep hole in the upstanding leg flush with the interior bottom of the sill can as the jaws are pivoted toward each other. A large surface area surrounding the die opening in the second jaw prevents marring of the sill can exterior surface.

Abstract: A sprocket including spaced rims with sprocket teeth confined between the rims. The rims cooperatively define a configured periphery with link-supporting arc portions located at the teeth tips and flat sections extended between the arc portions. As a side link approaches the sprocket, the leading lower corner (the toe of the leading footprint) passes over a flat portion to remain out of contact with the sprocket. The following supporting arc portion rotates up into the notch formed in the bottom edge of the side link to support the side link as it travels around the sprocket. The hammering effect of the leading lower corner of the side link impacting the sprocket of prior devices is avoided.

Abstract: A closer mechanism for a flexible gate is disclosed. The mechanism is mountable to a member at one end of the gate opening. A bail for receiving the upper end of a gate post is moveable toward and away from the stationary member by the pivoting motion of an operating lever. The mechanism provides a mechanical advantage to provide a force to tension the gate as it is closed. The mechanism has adjustable features for mounting the mechanism and adjusting the distance the bail is moved as the lever is pivoted. A lower loop is provided for receiving the lower end of the gate post.

Abstract: A guide bar for a mechanical harvester wherein the guide bar is repairable after bending. The guide bar is provided with a bendable section in a limited zone between the mounting bracket and the principal cutting portion of the bar. A hinge area is thereby created in the zone area to permit bending of the bar without breaking. The rails are removed within this hinge area. The saw chain traverses the short railless section during normal cutting action. Upon bending of the bar, the chain assumes its own curvature in traversing the section and will more readily jump the bar when bending forces are so severe as to likely break the chain.

Abstract: A hedge trimming tool having a fixed elongated blade mounted to the power head of the tool and a cutting blade mounted over the fixed blade and reciprocating relative to the fixed blade in the direction of the lengthwise axis. A leading side of the fixed blade has projecting fingers or teeth and the overlying portion of the cutting blade has projecting teeth that reciprocate across the openings between the fingers. The reciprocating teeth have sides configured in a complex curve forming an hour glass planar profile and an inverted U-shaped cross section. The U-shaped cross section is provided by curving the sides of the teeth downwardly whereby the teeth sides are angularly projected through the plane defined by the bottom surface of the blade. The cutting edges along the sides are formed by grinding faces through the portions of the teeth projected below the bottom surface of the blade. The faces are formed in a single pass of the grinding implement with the faces parallel to the bottom surface of the blade.

Abstract: A series of storage units simulating the capability of answering machines connected to a computer operated dispatch unit connected into a telephone system. The storage units are coded to represent calendar days. A user calls the dispatch unit and identifies the code of a selected day, to thereby inter-connect with the designated storage unit. Further touch tone signals actuate storage retrieval and record input functions of the storage unit. Scheduled events are thereby both retrieved from and recorded into the storage units. Multiple users are provided with remote control access to the storage unit. A master phone with a visual display is capable of retrieving the calendar day scheduled events visually with additional means for printing hard copies thereof.

Abstract: A guide bar for a chain saw having interior channels for conducting fluid to a nose end of the bar. The channel conducts fluid to the nose end of the bar where a sprocket is rotatably mounted. The sprocket has grooves formed in each side of its body for injecting fluid received from the center channel into the supporting bearing surface in the bore of the sprocket. The grooves are configured to inject fluid to the bearing surfaces regardless of the direction of sprocket rotation. The grooves which have open tops also provide for fluid flow between the side of the sprocket body and the side laminates of the sprocket nose. The grooves also provide an exit for fluid to flow out of the bearing surface as the grooves are positioned opposite the center channel as the sprocket is rotated. The flow of fluid through the grooves into the bearing area and the flow of fluid between the sprocket and the side laminates provides a hydraulic wall to prevent entry of contaminants into the sprocket.

Abstract: A bed for a recreational vehicle that is stored near the ceiling in the front portion of the vehicle when not in use and is lowered for usage. The bed when stored above the driver's area does not interfere with the operation of the vehicle. The bed is lowered into the seating area when made available for use. The bed movement is power actuated over a height difference of two and one-half to three feet. The seats are adjusted out of the path of the bed and the power mechanism is interrupted when items are in the path of the bed movement. The power actuator is contained within the bed frame and movement is controlled by a rack and pinion mounting.

Abstract: A chain saw guide bar assembly includes opposing outer laminates in spaced relation as defined by a wire structure lying generally about the periphery of the laminates, but spaced inwardly of the edge boundary thereof whereby a saw chain groove formation results as defined by an exposed or outward facing portion of the wire structure and exposed portions of the inner surfaces of the outer laminates. The wire structure advantageously provides, in combination with the outer laminates, a containment cavity for a foam-adhesive core laminate which expands upon curing to fill the cavity and to adhere to the inner surfaces of the outer laminates. A very rigid yet lightweight chain saw bar results with less production complexity and cost relative to that of other core laminate chain saw bars.

Abstract: A tool for finishing the aperture in the base of a cartridge case. The typical cartridge case has a cylindrical neck and the aperture is located on the axis that extends from the cylindrical neck. A pilot is provided on the shank of an aperture cutting tool coaxial with a cutter on the tool. A limit stop is provided above the pilot and the combination is adjustable and lockable at a desired position on the shank. The combination pilot and limit stop is positioned relative to the cutter so that as the pilot enters the neck, the cutter is guided into the aperture. The stop limit provides the exact amount of cutter entry for removing burrs but without enlarging the aperture.

Abstract: A cold pack for treating an injury of a subject person. A cooling media, e.g. of BLUE ICE is encased in elongate plastic closed end cylinders. The cylinders are inserted in parallel pockets formed in a wrapper, e.g. made of cloth with the interconnecting cloth material forming flexible hinges between the cylinders. Straps provided on the wrap enable the application of the pre-chilled cold pack to be applied to the injured area of the subject person. The container and plastic partially insulate the cooling media which has the doubly beneficial effect of reducing the cooling effect and extending the life of the cold pack.

Abstract: A portable lathe for performing machining operations on a stationary member. The lathe is of split construction permitting the lathe to be mounted on the member from the side of the member. Each of the end housings have removable sections that provide a side entrance to the bores of the housings. Parallel guide ways connect the end housings and support a moveable carriage assembly. The carriage assembly rotatably supports a rotating tool holder and carrier on a unique roller arrangement simplifying construction. The carriage assembly has removable support struts and the carrier and tool holder ring are splitable which provides a side entrance to the bore of the carriage assembly. The lathe is secured and aligned to the member to be machined by adjustable jaws provided on the end housings. Twin leadscrews provide motion to the carriage assembly and reduce the twisting and deflection experienced with a single leadscrew.

Abstract: A combination log debarking, log chipping unit having a debarking apparatus and a chipping apparatus mounted on a common chassis, the two apparatus are aligned for conveying logs from the debarking apparatus to the chipping apparatus. The two apparatus are separated by a space of about 6-10 feet to permit loose bark to be removed from the logs and thereby avoid bark contamination of the chip. A conveyor system between the two apparatus guides and conveys logs to the chipper. A single power source enables control over the feeding of the logs to synchronize log feeding with the chipper's chipping capability. A loader over the debarking apparatus provides convenient loading of the logs into the debarker. The power source and controls for the various operating components are all under the common control of the loader operator.
