Interlocking Clamp and Back Gage (also called fingered clamp and fingered back gage)—Recesses in the clamp permit projections on the back gage to push the work farther forward than if both clamp and back gage were solid and the clamp of sufficient width to hold the stock firmly.
Jog—To jog a pile against the gage is to strike it with a blow just sufficient to bring every sheet in the pile so that it touches the gage and in the same relative location with each other if all the margins are uniform.
Knife—A piece of tempered tool steel about one-half the width and thickness of the whole blade, forged into a piece of less expensive soft steel, in which holes can be drilled more easily for the bolts that hold it to the knife bar.
Knife Adjustment—Devices for lowering the knife-bar to compensate for the wear of the knife and for tilting it in case the knife edge is ground out of level.
Knife-Bar—A rigid carrier for the knife. The best style takes the down thrust and side thrust of the knife directly upon a solid shoulder planed in it, instead of the knife back abutting against the points of adjusting screws.
Knife-Bar Motion—A mechanical way of imitating the action of a draw shave in pulling down the knife. The nearer it is to the hand method, the more simple and successful it is. Rods connected to each end of the knife-bar and pulled down by simple cranks at each end approach nearest to the method of human hands.
Lift—The pile of paper or other stock cut and handled at one time.
Marker—A part of the clamp on some machines, separate from the pressing part, that may be pulled down by a treadle to show where the knife is going to cut.
Motor Bracket—A support attached to one side or top of the cutter to which the electric driving motor is firmly bolted.
Oil Boxes—Channels containing oily waste which allows the oil to seep slowly upon the bearing.
