Abstract: A bullet seating die for use with an ammunition reloading press, the die including a member having an elongate bore for receiving a cartridge and a bullet seating member mounted in the bore. The bullet seating member is shiftable longitudinally within the bore by operation of a micrometer screw. Coacting grooves and a spring biased member produce a manually and audibly sensed click stop that indicates to the user preselected intervals of adjustment of the bullet seating member in the bore.

Abstract: Chain saw bars having overlapping slots adjacent locations where the saw chain leaves the driving sprocket and in the region of the nose end of the bar are provided. In these areas, where the chain tends to pound against the bar, the slots dampen the vibrations between the outer portions of the bar rails and the interior of the bar and greatly reduce noise emission. The slots also provide cooling of the saw bar.

Abstract: A rectangular container for a saw chain is provided with a transparent plastic lid and a foraminous bottom. Freshly sawn wood chips are placed in the container after which a movable slide is located adjacent the level of the chips. After shaking of the container, a predetermined reduction in chip level as measured by the slide will indicate that the saw chain requires servicing.

Abstract: A drill bit having a generally cylindrical body with a working end and flutes extending along the body. The working end is formed with a central work-engaging point and a pair of slitting spurs spaced outwardly from the point adjacent edge margins of the body. Convexly contoured portions interconnect the point and spurs to permit sharpening with a round file.

Abstract: The specification discloses a chain saw having a saw bar which is fastened to the frame of the chain saw so that most of the saw bar is outward of the chain saw frame (referred to as the forward portion), which portion is exposed for effective cutting, but with a lever portion rearward of the frame and the drive sprocket of the chain saw for improved mounting and adjustment. The saw bar forms a part of a cassette which also includes a drive sprocket trapped in the saw bar and a saw chain extending around the sprocket and the forward portion of the saw bar. A cover has clamping bosses clamping the saw bar to the frame, and an adjustment screw engaging the rearward end of the saw bar is mounted on the frame at the rear thereof so that it is readily accessible.

Abstract: The specification discloses a motor housing, with a handle of the circular saw type, and a cantilever saw bar carrying a saw chain is secured to the housing in a position extending downwardly from a guide foot of the housing. A retractable guard bar normally is held in a position holding a guard loop around the nose end of the saw bar, the guard bar being positioned at the rear of the saw bar. The guard bar is mounted slidably on the motor housing, and, when a latch is manually released, the guard loop may be pushed up along the saw during a boring (nose cutting) operation. In an alternate embodiment, a foot attachable to a foot of a circular saw motor carries a saw bar and a guard bar with a guard loop surrounding the nose end of the saw bar.

Abstract: An elongated cone like member having a pointed end and a relatively large blunt end with the intermediate portion flaring outwardly from the pointed end to the blunt end, and serrations formed in the member adjacent the pointed end. The pointed end of the member is plunged into the end of a short length log and the blunt end is struck by a driving maul. The serrations prevent the member from bouncing back out of the wood and the multi-directional flaring of the intermediate portion applies splitting pressure radially in a symmetrical pattern from the point as the member is driven into the wood to thereby split the log where it is weakest.

Abstract: A tool for driving nails into hard surfaces wherein the driving power is provided by cartridges of explosive powder. The cartridges are contained in strips with a single strip containing a multiple of cartridges, in the order of ten. The improvement comprises the mechanism for feeding the strip of cartridges in increments automatically through the tool and for retaining the tool piston in its ready to be fired position. The feeding of the cartridges is accomplished by a camming finger connected to the barrel of the tool which progressively engages successive following lugs on the strip to move successive cartridges of the strip into place within the firing chamber as the tool is repeatedly engaged and disengaged with a work surface. A ring having a double loop configuration frictionally grips the piston to resist accidental displacement.

Abstract: Integrated tie strap and rivet assemblies for saw chains are made by the steps of rough cutting, coning, coining and trimming a length of elongate bar. The integrated tie strap and rivet assemblies thus formed replace the separate tie straps, rivets and concentric shoulders heretofore used in saw chains.

Abstract: A guide bar for a chain saw having a main body portion that is symmetrical so as to be invertible, i.e., to reverse the top and bottom edges, and including a nose portion having fixed top and bottom positions that is removably attached to the outer end of the main bar portion. Said nose portion is non-symmetrical with the upper quadrant of the nose sharply curved away from the top edge and the lower quadrant gradually curved back to the bottom edge. Whereas the main body portion can be inverted, the life of that portion of the bar is greatly increased.

Abstract: A flat sheet metal plate defining a reference plane on one side. Said plate having first and second sections and an intermediate section. The first and second sections being flat and in a common plane, and the intermediate section formed into a semi-circular loop with a center portion of the loop removed. The remaining portions of the semi-circular loop provide a pair of guide lugs to guide a round file. The first and second sections are adapted to rest on the depth gauge and cutter of a cutting link in a saw chain with the guide lugs straddling the chain and aligned with the gullet of a cutting link to guide the file in a desired orientation against the cutting edge of the cutting link.

Abstract: A rod having one end adapted to be secured in the chuck of a power tool, said rod having a grinding portion for sharpening the cutting edge of a saw chain cutting link when rotatively driven by the power tool, and a guide fixture supported on said rod including guide surfaces adapted to rest on the top plate and depth gauge of the cutting link and thereby locate the grinding portion of the rod for proper sharpening of the cutting edge of the saw chain.

Abstract: A carrier adapted for rotation about an axis so as to define a circular path at the outermost extension of the carrier. Anchoring means positioned on the carrier at spaced locations along said circular path. A flexible elongate member extending between and fastened to said anchoring means. At least one cutter mounted to the elongate member between a pair of the anchoring means. Said cutters extending outwardly of the circular path and maintained in said extended positions for impact cutting at least partially by the centrifugal force produced by rotation of the carrier. Said flexible member permitting rearward or inward flexing to withdraw the cutter behind the path defined by the carrier upon striking a solid object, e.g. a rock.

Abstract: A flexible rubber strip has openings slightly smaller than the shank of a power load spaced along its length. Power loads having shank and head portions are inserted through the openings up to the head portion in which position the power loads are gripped by the rubber to hold the power loads until forceably removed. The strip with power loads is contained in a box with one end of the strip protruding through an opening in the top of the box. An operator of a powder actuated tool grabs the protruded end of the strip and pulls a section of the strip from the box. He inserts the first power load into the cartridge receiving chamber of the powder actuated tool and by peeling the strip over the head portion of the power load separates the power load from the strip. The box containing the strip can be clipped to the operator's belt or contained in the pocket of an apron.

Abstract: A guide bar has a groove extending along the top and bottom edges and continues in a semi-circular path around the outer end. A cutting chain has drive tangs that slide in said groove to guide the cutting chain along the edges of the bar. A thin rigid plate is fixed to one or both sides of the guide bar near the outer end thereof and extends slightly past the outer end to form a safety rail that reduces the degree of hooking that is caused by the depth gauges and cutters of the cutting chain digging into or hooking onto a tree or branch being cut.

Abstract: A loader having an elevated operator's platform mounted behind the cab of a truck. A ladder positioned to the side of the loader enables an operator to climb up to and down from the platform. The ladder includes a first standard fixed to the truck and/or loader, and a second standard carried by the first standard through interconnecting rungs normally spaced from the first standard outwardly of the acceptable travelling width of the truck. The outer standard and interconnecting rungs are pivotally connected to each other and to the inner standard whereby the outer standard can be pivoted upwardly against the inner standard to substantially reduce the width of the ladder to a position within the acceptable travelling width of the truck.
