Abstract: In stanchions of the type used for milking and/or feeding but primarily the feeding of cattle, a stanchion structure having vertically spaced upper and lower horizontal members with swing pipes defining spaced positions for accommodating cattle in spaced, captive relationship and having intermediate vertical support posts, an improved structure is provided employing an extending draw bar having spaced notches or slots wherein a locking member is pivotally secured to each of the swing pipes so that the individual swing pipes may be selectively opened or closed either individually or in unison to permit free access or egress from the spaced, cattle positions by the cattle and wherein the locking mechanisms are protected by the swing pipe structure so as to inhibit opening of the locking mechanism by cattle. The invention is also directed to a conversion kit for existing stanchion structures to provide for the locking feature in a simple and economically feasible manner.

Abstract: A doorlatch knob assembly has a knob insert of a hollow knob projecting through a door mounted rose secured rotatable by a drive washer which, in turn, receives the outer end of a doorlatch connected spindle projecting outwardly through the drive washer drivingly engaged therewith, through the insert and into the hollow knob. A fire resistant shield is closely telescoped and engaged with the insert receiving the spindle outer end therein so as to close off the previous opening from the hollow knob inwardly and preserve the integrity of the spindle retainment of the doorlatch mechanism against flame penetration upon heat destruction of the knob. The shield may have formation engaging the spindle outer end to aid the drive washer for rotatably driving the spindle. Where a turnbutton shaft is involved, it will also be formed of fire resistant material and will be closely telescoped by the outer end of the shield, otherwise the outer end of the shield will be closed.

Abstract: A roll holder of the type for mounting split-core rolls of tissue is positioned in a dispenser moveable from an upper dispensing position to a lower exhausted position. A latch retains the roll holder in the dispensing position until tissue exhaustion permits relative movement between the split-core parts with consequent roll holder part movement to release the latch for movement of the roll holder to the lower exhausted position. The improvement includes blocking members at roll holder opposite ends normally retained inactive permitting the foregoing latch release by presence of the split-core parts, but automatically moving to active preventing latch release upon a lack of core retention. This means that the split-core must remain for proper roll holder functioning, and also that a solid core roll cannot be used with core stripping to cause roll holder functioning, in either case avoiding core stripping from the roll holder which can result in littering.

The provision of the knob-dial control member in kit form, having selectable knob members, provides a means whereby inventory is substantially reduced and a service man has the ability to service a large number of cold control regulators without the need of having a large number of specialty repair and replacement parts.

Abstract: An adjustable ramp includes a ramp member supported in an adjustable suspensory frame. Adjustment of the suspensory frame changes the angle of incidence of the ramp member to the supporting surface on which the ramp is located. A resilient ramp member is provided in one embodiment which is maintained in curvilinear, flexed attitude on the supporting frame by the moveable connections of said ramp member to said suspensory frame.

Abstract: The present invention discloses a rotary engine having a cylindrical stator with a plurality of radially arranged cylinders each having a piston, a shaft is rotatably mounted co-incident with the longitudinal stator axis, and an orbitor having a cylindrical interior encompasses the stator. Sequentially phased reciprocation of the pistons is transmitted to the orbitor which orbits about the shaft axis in a "polishing-cloth" motion without rotation or revolution of the orbitor. A gear mechanism converts the orbital motion of the orbitor to rotation of the shaft.

Abstract: A conventional keyed, pin-tumbler lock has an abutment portion formed on the key axially adjacent one of the key notches at the side thereof axially inward of the lock cylinder which normally axially obstructs that lock pin when the key is properly inserted in the lock cylinder key slot to prevent normal withdrawal of the key from the lock cylinder while still permitting free rotation of the lock cylinder by the key in its normal locking and unlocking movements. A key removal member is axially insertable into the key slot adjacent the key within a key axial recess and has a leading angled surface portion terminating axially in a raised surface portion which progressively move and ultimately retain that particular pin from its key pin notch and the key abutment portion obstruction, thereby permitting normal key removal from the lock cylinder.

The air and liquid sources may be in a common container.

Abstract: A movable partition construction which employs a unique overlap joint feature and means for erecting the individual panels in place to obtain a movable partition which has at least a one hour fire rating to thereby provide fire resistive partition wall construction, which is easily erectable and thereafter demountable should the partitioning or removal be desired. The panels are prefabricated on the factory site with a variety of exterior surfaces and are shipped to the building or job site where they are easily positionable into partition wall-forming members permitting the erection of partition walls in relatively short periods of time compared to existing prior art expedients. The resultant wall is fire-resistive and aesthetic in appearance.

Abstract: An end of an inlet tube communicates through a tank wall with a water supply and an inner end of the inlet tube communicates through a float controlled valve with a generally vertically downwardly extending outlet tube. Thus, the tank water level through the float controls closing and opening of the valve admitting water through the inlet tube, through the valve and down the outlet tube flowing into the tank from the outlet tube lower end. The outlet tube is selectively vertically adjustable to adapt to various depths of tank by being formed of telescoped parts normally retaining a determined telescoping by a projection of one part being radially interengaged in a groove of the other part. Depending on the particular construction, the tube part telescoping may be selectively varied by either relative rotation between the parts or by disengaging and reengaging the interengagement between the parts. Through a slot and lock collar arrangement, the tube parts may be totally telescopically separated.

Abstract: A demountable, readily portable photo vignetting kit includes a mounting plate for securement of the assembled kit to the lens mount of a camera and track means on said mounting plate for moveably orienting a vignetting screen standard to permit various photographic effects to be achieved during the taking of a photograph.

Abstract: Improved water bed construction where, in one embodiment, two spaced inflatable members are positioned along the two lateral edges within a water bed frame with a separate water filled mattress being positional thereover with the conventional safety or water liner, wherein the inflatable members are filled with liquid or gas so as to have less resiliency than the water filled mattress portion, whereby ease of entry and exit onto the water mattress is facilitated. In another embodiment a liquid or gas supply means with appropriate controls is utilized so as to selectively and preferentially fill the lateral inflatable members to desired pressure, or alternately, to deflate same to selectively alter the resiliency thereof to facilitate supporting conditions of the water mattress.

Abstract: Telescoped inlet and outlet tubes having a valve between upper extremities thereof are each formed with end telescoped, upper and lower parts, the tube upper parts being assembled movable together and the tube lower parts being assembled movable together for simultaneously increasing and decreasing the respective tube end telescoping to selectively change the overall height of the ball cock. Positive securement in a height adjusted position against straight vertical relative movement is obtained by positive radial interengagement between the outlet tube parts with either selective relative rotation or selective release of the interengagement with re-engagement providing the height adjustment. An upper main case covers the valve assembly and an inner end of a float connected valve actuating lever projects into the upper main case to a case slot, being pivoted therein and operably connected to the valve.

Abstract: A lockset of the type having a bolt reciprocal from and to a door edge by an operating mechanism including a crank hub and locks at opposite door faces has tubular torque blades between the locks and crank hub for transmitting rotative motion from the locks to the crank hub and ultimately to the bolt for the bolt reciprocations. Both of the torque blades have tubular inner ends of D-shaped cross section with one extending axially a major part of a crank hub D-shaped cross section axial opening and telescoping the other within the crank hub. Outer enlarged tubular ends of the torque blades are telescoped by ends of lock plugs of the respective locks and have partially circumferentially extending slots formed therein receiving radial tongues of washer-like members positioned circumferentially over the lock plug ends. Thus, the torque blade inner ends are single position, rotative drive connected to the crank hub and outer ends thereof are lost motion drive connected to the locks.

Abstract: A preferably plastic film flower sleeve has side edge heat sealed front and back panels tapering inwardly in downward extension providing upper and lower open ends. Each panel has a centralized nonperforated area which increases progressively in transverse width during its downward progression bordered by transversely opposite perforated groups decreasing correspondingly in transverse width during downward progression, the perforated groups also being defined by nonperforated upper and lower end portions. A flower sleeve may be rearwardly rack suspended and forwardly hand suspended during insertion of a flower bunch downwardly therein, the flower bunch stems being maintained forwardly aligned with the progressively increasing nonperforated areas to avoid snagging and the stems ultimately projecting from the sleeve lower end while the increased size flowers of the bunch automatically transversely expand the sleeve perforated groups.

Abstract: An elongated cylinder having a hollow cylindrical extension member received press fit in a discharge open end thereof normally receives an elongated plunger in an opposite receiving open end with said plunger having a piston-like end within the cylinder selectively slideable along the cylinder to dispense fish bait of putty-like consistency from the cylinder through the extension member. The cylinder preferably has a uniform outer cylindrical surface except for an annular, outwardly projecting portion at the plunger receiving end thereof and a finger gripping ring is telescoped over the cylinder outer surface selectively slideable therealong movable to the cylinder plunger receiving end against the outwardly projecting portion for normal bait dispensing use of the cylinder and plunger, but movable to the cylinder discharge end for removal of the plunger from the cylinder and insertion of the cylinder plunger receiving end into a supply of fish bait to fill the same.

Abstract: This invention relates to a vehicle guidance system where the vehicles incorporate wheels having tires thereupon to follow a track of predetermined cross-section. The vehicle is provided with sensors to continuously sense the lateral location of the vehicle relative to the cross-section of the track and the yaw angle of the vehicle with respect to the longitudinal axis of the track. A modulator receives the output of the sensor to drive the steering system of the vehicle in order to correct for deviations of the vehicle from its predetermined relationship with the track contour.

Abstract: An essentially closed hollow body of the float receives liquid in a lower portion for ballast and air in an upper portion for floatation with a vertical guide sleeve therethrough being offset at one side of the hollow interior slightly spaced inwardly of a part of the body sidewall. A liquid and air flow opening is formed through the body sidewall part horizontally centered relative to the guide sleeve so that flow paths are created segregated approximately one half around either side of the guide sleeve. By arcuately forming the body interior and the guide sleeve, not only are the flow paths smoothly arcuate, but the circuitous nature thereof muffles echoing sounds created within the hollow body from passing outwardly of the body through the flow opening.

Abstract: The skeleton discharge mechanism receives the leading edge portion of scrap skeleton sheets one at a time from a press at an entrance portion of a support surface exactly positioned by the press relative to a pick-up station and transversely spaced pairs of engagement members move partially upwardly through the support surface on a timed basis to engage the sheet leading edge through press formed part openings. The engagement members are secured to chains constantly moving over sets of sprockets along closed paths and after engaging the sheet leading edge move longitudinally along the support surface to a surface exit portion pulling or dragging the sheet through the mechanism.
