Abstract: An elastic band cutting apparatus is disclosed which includes a movable blade mounted proximate an elastic band stock holding structure for displacement to effect cutting of the tubular stock. The apparatus also includes a movable anvil which cooperates with the blade to engage the cut elastic bands so as to grip the same between the blade and anvil. After cutting is completed, one of the anvil and blade are displaced with respect to the blade so as to break any bonds which have formed during the shearing process. The apparatus further includes stock feeding assembly which will advance the stock to the cutter and eject previously cut and separated bands onto band manipulating apparatus. A method for cutting and separating elastic bands also is disclosed.

Abstract: A saw blade guard for a table saw or the like includes a flat blade guard arm which is coplanar with the circular cutting blade and has a thickness no greater than that of the blade. The guard includes a yoke portion mounted on a bearing on the blade arbor below the table such that the yoke is allowed to rotate independently of the rotation of the arbor. The guard arm is semicircular in shape and extends through the kerf in the workpiece produced by the saw blade and down through the blade slot in the table to a point adjacent the yoke. The yoke includes a radially radial extension which supports the arm below the table. A roller mounted on the outer free extremity of the guard arm above the table is engaged by the leading edge of the workpiece and forces the arm to rotate a sufficient amount to expose the workpiece to the blade.

Abstract: A piercer used for the manufacture of clothing and the like comprises a frame with upper and lower parallel disposed arms. A channel plate extends uprightly from the free end of the upper arm and includes an associated guide plate or guide rail extending lengthwise thereof and a slider which is movable up and down the guide rail and fixedly carrying a rotary drill with its drill bit directed downward. A reflector is disposed below the tip of the drill bit and a lamp is disposed to direct light toward the reflector so as to be reflected thereby to project a marker to a location which is directly below the tip of the drill bit, the reflector being movable away from the path of movement of the drill bit during its upward and downward movement.

Abstract: A die or like tooling is precisely oriented in a horizontal attitude for lowering into a tool-receiving recess in a machine frame by moving it against a guide member projecting above the tool holder and then moving both tool and guide member downwardly to seat the tool. To ensure proper alignment and attitude, the guide member and tool have a cooperating recess and projection. The machine tool desirably includes a locking member to retain the members in the depressed position.

Abstract: A fore chamber assembly of a nailing gun serially feeds nails by gravity through a channel into a firing chamber. A nail head fence prevents the heads of trailing nails from underriding the heads of preceding nails and getting more than one nail in the firing chamber. The fence is vertically adjustable to work on different thickness nail heads. A safety link prevents firing of the gun unless the gun abuts the structure to be nailed and in that attitude applies a friction lock to nails in the fore chamber to prevent kickback of these nails upon gun firing. This lock is through a sliding cam and lever that engages a resilient button that in turn engages some of the nails. A feed magazine has spaced rails defining a slot that accepts loose nails in any orientation so long as their heads are on the rails with the nail shanks in the slot. The magazine rails are secured together by a cover that overlies the slot and nail heads and depending flanges that attach to the rails.

Abstract: A casing article for use in automatic production of frankfurters and the like includes a tubular core and a shirred casing strand mounted to the core. The core can function as a disposable stuffing horn or it can be placed over a stuffing horn. When used as a stuffing horn, the core has one end receivable in the discharge of the stuffing machine and a second end including a flange which is engaged and rotated by a rotation chuck of the stuffing apparatus.

Abstract: A method and apparatus for fine shearing a metal workpiece involves placing the workpiece on a stationary die surface for support and driving a single punch against the workpiece such that at least a portion of the workpiece is placed in compression. The punch is then driven into and through the workpiece along a predetermined path which has a first directional component both perpendicular to and directed toward the die surface and a second directional component both parallel to the die surface and directed into the compressed portion of the workpiece. The punch is driven with a force having components both perpendicular to and parallel to the path of the punch. The force component perpendicular to the punch path is large enough to keep the compressed portion of the workpiece in a plastic state. The force component parallel to the path of the punch is large enough to overcome the shear strength of the workpiece along the path.

Abstract: In a drill hammer a motor driven striking mechanism is provided with two air cushions of changeable volumes, through which impact energy is transmitted from the motor to a reciprocating striker which in turn transmits the energy to a tool of the drill hammer. When the striker moves in the direction towards the tool both air cushions act on the striker whereas when the striker moves away from the tool only one of two air cushions acts on the striker.

Abstract: A method for bookbinding on a continuously-moving, constant-speed conveyer belt operation with the case or back-strip being centrally located on the axis of motion. As the case is formed between opposing rotary irons, glue or paste is then applied to the upper insides of both sides of the case. A book block is next dropped on one side of the case, the book block is aligned to register with the case; and the other side of the case is folded over to fasten to the upper side of the book block to form the book and prepare it for pressing and crimping of the building-in operation, without any interruption of the motion of the book along the conveyer system.

Abstract: A blade guide for saw blades consists of a number of small cemented carbide plates which are moulded at intervals onto a base plate of steel or the like by means of a metal, such as brass or bronze, or with a plastic material, which is considerably softer than the carbide in the plates and presents a smooth surface of carbide plates in the moulding material to the surface of the saw blades.

Abstract: A tube cut-off apparatus includes a horizontally moving scarfing blade which opens up the top of a tube permitting a vertical moving cut-off blade to move through the opening and finish cutting the tube. An upper die plate supports the vertical cut-off blade and a locking cam arrangement includes spaced vertically extending cams which provide for longitudinal movement of clamping slides in turn opening and closing jaws of die blocks which support the tube to be cut. A horizontally movable slide member carries a scarfing blade which cuts horizontally the upper tube portion and moves out of the way to permit the vertical blade to shear through the tube. The scarfing and clamping arrangement is actuated entirely by the mechanism on one side of the apparatus with the cams performing the clamping function as well as the actuation of the slide member.
