The operating' sliatt for the peritoratinev cutter element 4G is similar in all respects to the shatt 16, as indicated at 16, the ends ot the siiatt 16 however, being' rotatably mounted at the ends in suitable bearings, and provided with ka gear 50, on oneend. .interinesliing' with the gear 51 on the shatt 52, which is similar in construction to the shalt 16', and which takes-the place ot the rollers 2S et the construction shown in Figure 4the female elements 48' receiving` the projectine' ends of the peitoratingr projections 4'4" From the construct-ion shown in Figures `12 to 14, it will be clear that the cutter element 4G and the female elements 48jare adjustable on the shatts 1G and 52 respectively, to any desired position, in orde-r to pertorate paper passed therebetween at a desired point. it beingfunderstood that a pluralitf,7 of these. cooperating perforatine' elements, may be provided on the shatt 1G and 52, in the saine in'aiiner that a plurality of cutter elements are provided on the shalt 1, the operation being` similar in all respects, but producing a series of small pertorations in the paper in the place ot a series ot small slits,frvhich is desirable, in providing a line for separation of certain kinds of paper. It will thus be seen that when the shaft 16 is driven in the same manner as the shaft 1G, a corresponding` driving movement will be imparted to the shaft 52, so that the openings a8 will always be in mesh, or at proper relation for receiving,` the projections All? of the male 1 erforating elements as they perforate paper passing therebetween.
From the foregoing Adescription, it should be clear that a very simple form of perforating machine has been provided, which will eiliciently perforate or slit paper, in any desired manner, and which comprises relatively simple n'ieans for elfecting` the desired result, and producing perforations or slits of a size substantially smaller than is now generally used in the art, in order to provide a .more easily perforated edge or line of perforationA` in a sheet of paper. lt should also be clear that cutting and perforationy elements of special form have been provided which are simple in construction, and are readily removable and interchangeable on the operating shaft l5, the securing means therefor beimul` readily adjustable axially of the shaft for holdingl said cutter elements in a desired position thereon.
lWhat is claimed is:
1. A perforating i'nachine including a table, a pair of bearing` members mounted on opposite sides of the table, said bearingmembers being provided with slidable bearing` blocks, a rotary cutter shaft mounted in said slidable bearing' blocks, means for rotatinpy the said cutter shaft, a plurality of removable and adjustable cutter elements mounted on said cutter shaft, a cushion roller mounted for rotation in said bearingI members and extending; through a slot in said table, and means for moving said slide bearings for projecting' said cutter elements into engagement with said cushioningl roller for effecting perforation of a sheet material fed between said cutter elements and said roller, a rod mounted in said bearings and extending transversely of the table above the same, and a plurality of fingers adjustably mounted on said rods having the end portions extendingY into proximity to the cushion roller for holding the sheet material in contact with said rollers.
2. A perforating machine including` a table, a pair of bearing members mounted on opposite sides of the table, said bearingY members being provided with slidable bearing blocks, a rotary cutter shaft mounted in said slidable bearing` blocks, means for rotating said cutter shaft, a plurality of removable and adjustable cutter elements mounted on said cutter shaft, a cushion roller mounted for rotation in said bearing members and extending through a slot in said table, means for moving said slide bearings for projecting' said cutter elements into engagement with said cushinning,v roller for effecting` perforation of a sheet material fed between said cutter elements and said roller, slide bars connected with said slide bearing-bloc Is, and slid-ably mounted in said bearing,` members, links connecting with said slide bars, an operating;` shaft mounted for rotating; movement below the table, a foot pedal for operatinn` said operating shaft, said operating` shaft having crank arms thereon connected with said links, and means for norii'ially projecting said slide bearings upwardly in the bearing` members, said foot pedal serving for operating' said slide bars for loweringthe operating shaft to project the cutter elements intoengagemcnt with said cushioning roller.
