Abstract: A laminate and method of making same is disclosed. The laminate includes a base layer and a low melt layer directly or indirectly bonded on one side thereof to the base layer and a product layer adhered to the other side of said low melt layer; the low melt layer extends beyond the product layer along a peripheral portion thereof. The low melt layer when in registry with an adjacent laminate and subjected to heat bonds with and forms a substantially water tight seal with the adjacent laminate. Various base, low melt and product layers are disclosed.

Abstract: A back pack assembly which is convertible into a tree seat has a rigid, substantially planar member to which one end of each of a pair of elongated frame members is pivotally attached at either side of the planar member. Frame extension members are pivotally attached to the distal ends of the frame members, and a V-shaped blade member is adapted to be mounted to the distal ends of the extension members.

Abstract: An improved carpet beveling head wherein a pivotally mounted cutting blade is retained in operative engagement with a rotary cutter. The pivotal mounting, which facilitates adjustment of the device, is retained in such position by exertion of a securing end pressure thereon.

Abstract: An apparatus for placing carpet samples one on top of the other in a neat, uniform stack to minimize the need for human involvement in the stacking process and to minimize the time required in stacking operations by quickly and automatically bringing samples individually into the apparatus along a conveyor belt, sliding the samples out over adjustable bars, dropping the samples from the bars one on top of the other to form a stack on a movable platform, lowering the stack by lowering the platform in response to the size of the stack and then removing the stack by a conveyor to a point where it can be easily picked up.

Abstract: A carpet tube dispensing apparatus, used in combination with a carpet roll-up machine, comprises a large hopper for holding a number of tubes therein and an outlet from which tubes can leave the hopper for use in the roll-up machine. A tube collecting and dispensing device is located at the outlet opening to regulate the dispensing of tubes and provide only one tube at a time for use in the roll-up machine, and a tube stirring device stirs the tubes within the hopper to loosen entangled tubes and insure that tubes flow freely to the outlet opening.

Abstract: An apparatus for cutting sheets of carpet into a number of rectangular swatches comprises a gang slitter including a plurality of disc cutting blades mounted on a single shaft for making a plurality of parallel cuts in the sheet of carpet moving through the blades, thus cutting the carpet into a plurality of long strips of predetermined width, and a cross cut blade which moves across the sheet of carpet to make a cut in the carpet perpendicular to the plurality of parallel cuts, thus cutting the long strips of carpet material into shorter rectangular swatches. The sheet of carpet material is automatically fed through the gang slitter and stopped for the cross cut, and the swatches are discharged from the apparatus.

Abstract: A firing nipple for use in muzzle loaded firearms comprises a duct of large internal diameter into which a cartridge shaped percussion cap can be inserted and a firing ridge against which the rim of the cartridge shaped cap is forced to ignite the cap.

Abstract: Pre-cut square carpet samples are placed edgewise on the first of a stepped series of pairs of sample conveyor belts, the belts of each pair being separated to accommodate between them a power-operated beveler. An inclined sheet metal backing plate is provided adjacent each pair of the conveyor belts and has a cut-out through which another series of stepped belts operates immediately above each pair of conveyor belts in a plane at right angles thereto, the second series of belts spanning the spaces between the conveyor belts of each pair. Spring pressure bars lie immediately forwardly of and parallel to the belts of the second series and resiliently press the carpet samples into contact with the belts of the second series to assure firm contact of each edge of every carpet sample with the powered beveler as each sample passes thereover.

Abstract: Sheet material such as carpet is moved along its length between lower and upper rollers of a cluster or rotating rollers. The rotating rollers form the sheet material into a spiral roll, and as the size of the spiral roll of sheet material increases, it urges one of the upper rollers of the cluster to open up away from the other rollers to form an upwardly facing concave arrangement of rollers, and as the spiral roll of sheet material continues to increase, it becomes supported on the upper rollers of the cluster with its free end extending downwardly between the upper rollers so that the upper rollers exert roll-up forces about a major portion of the circumference of the spiral roll of sheet material. When a predetermined length of sheet material has been accumulated in the spiral roll, the movement of the sheet material is stopped, the material is cut, and the upper rolls in the cluster of rolls are manipulated so as to eject the accumulated spiral roll of sheet material from the cluster of rollers.

Abstract: A carriage-mounted sewing machine with special stitch forming means and an advance power trimmer are driven as a unit along the rails of a railway sewing machine bed by operation of the sewing machine motor and a unique clutch arrangement coupled with the carriage train drive for the railway bed. The stitching mechanism features an improved looper arrangement whereby precisely the necessary degree of slack is produced in the butt seam stitches to enable the spliced carpet sections to "butt out" perfectly without a gap and without overlapping at the butt seam or buckling. A specialized presser foot and throat plate arrangement allows the butt seaming of carpet sections up to two inches in total thickness. Carpet scrap is reduced to a minimum.
