PERFORATING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 764,098, dated July 5, 1904. Application filed December 26, 1902. Serial No. 136,554. (No model.)
To (tlZ whom it wmy concern:
Be it known that I, J AMES B. ALLEN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Perforating-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to improvements in perforating-machines; and its object is to provide a foot-power machine the operatingle vors of which are so arranged as. to give a maximum amount of power with the expenditure of a minimum amount of force and are so mounted upon the frame as to greatly reduce the liability of breaking the frame.
It is also an object of this invention to provide a machine adapted to perforate sheets of any size and to so construct the die-casings that they may be easily and quickly adjusted to change the spacing of the holes to be punched or removed and others carrying dies and punches of a different size inserted.
A further object of the invention is to provide the machine with a cheap construction of punch and with certain other new and useful features, all as hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure l is a section of a device embodying my invention on the line as w of Fig. 2; Fig. 2, a plan view of the same with portions broken away to show the construction; Fig. 3, a detail showing one of the die-casings and its supporting-bar in vertical section; Fig. 4, a detail showing the manner of securing the gage-bar to the table, and Fig. 5 is a detail showing one of the punches in perspective and in an inverted position.
As shown in the drawings, 1 is the machineframe, the end portions of which are connected at their upper ends by the two parallel supporting-rods 2, upon which rods are mounted the supporting-bars 3, said rods passing through openings in the ends of the bars. Each of these bars is cut away at its upper side to form a channel therein to receive the lower end of a die-casing 5 and within which channel the casing is detachably secured by forming said channel with an undercut side 6 to engage the slanting front side of the easing and providing a wedge-block 7, having a beveled side forming an undercut to engage the slanting rear side of said casing. When the block is drawn into the channel by the bolt 8 passing upward through an opening in the bar, it wedges between the rear side of the channel and the casing, and forcing the easing into contact with the front undercut side of the channel firmly holds the same in place. Each casing is slitted inward from its front side at 9, and avertical opening is formed therein above the slots to receive the punch 10, which consists of a rectangular bar 11, formed with ears 12 at its upper end, between which one end of thelever 13 is pivotally secured by apin ll, passing through the ears and through an elongated opening 15 in the end of the lever. The lower end of the punch-bar 11 is provided with a rectangular groove 16, and thepunch proper or head 17 is formed with a tongue 18 to project into said groove and is brazed therein, thus greatly facilitating the manufacture of the punch, as the head may be accurately formed, then tempered, and quickly secured to the bar. The heads 17 may be of any desired shape to punch any form of hole, the form shown being for punching holes in the leaves of loose-leaf ledgersl Secured within the lower side of the slot 9 of each casing is the die-plate 19, having an opening to fit the punch-head 17, and below the opening in the die the casing and supporting-bar 3 are each formed with an opening to allow the punchings to fall through. To insure the accurate alinement of the punch with the die, the opening in the casing within which the punch moves is made somewhat larger than the punch-bar, so that when the machine is set up the punch may be set loosely into the opening, with the punch-head in its die, and Babbitt metal 20 poured in around the punch-bar.
WVithin the rear end of each slot 9 is a stopplate 21, which forms an abutment for the edge of the paper to determine at what distance the hole will be made from said edge, and integral with said stop 21 is an adjustingrod 22, which extends rearwardly through an opening in the casing and is held from moving therein, when the stop is adjusted to any desired position, by a set-screw 23. On the frame are forwardly-extending integral brackets 24 to support a table 25, to each end of which table is hinged an extension-leaf 26,
and in the face of the table are cut longitudi nal grooves 27, extending inward from each end thereof, and over these grooves are secured plates 28, two for each slot, the adja- 5 cent edges of which are spaced apart to leave a slot in the face of the table. A gage 29 for the paper is secured to the face of the table by a bolt 30, the head of which is squared to fit the grooves 27 and the shank of which projects outward through the slot and through an opening in the gage and is provided with a thumb-nut 31 to engage the gage and bind the same. Two of these gages are used, either one of which may be readily detached, when 5 it is desired to punch two or more holes nearer together than it is possible to place the punches, the paper being placed against the gage at one end of the table and one hole or set of holes punched, then the paper moved 3 into engagement with the gage at the opposite end of the table to punch the adjacent hole or holes.
The punches are each actuated by one of the levers 13, which extends rearwardly some 35 distance and is fulcrumed on the upper end of a post 32, extending upward from the supporting-bar 3, so that when power is applied to force the rear end of the lever upward the upward strain on the. post, which tends to 4 break the supporting-bar, is counteracted to some extent by the downward force of the punch.
Pivoted at its upper ends to the frame and hanging downward with its lower end adjacent to the floor is a U-shaped lever 33, pro- ,vided with a treadle 34 at its lower end, and secured to its side members at a short distance from its pivots arc the arms 35, which carry a cross-rod 36. Connecting-rods 37 are 5 provided with eyes at one end to receive the by the foot of the operator the punch will be moved downward with great force because of the great leverage obtained by this arrangement of levers. By this arrangement very large sheets of paper may be punched, the
punches are operated by separate levers,
which extend rearwardly, and there is nothing in the way at either end of the machine to prevent the paper from being inserted edgewise into the slots of the die-casings, the pa- 5 per being supported by the table, which may be extended by raising the leaves to support large sheets.
The punches, their casings, and operatinglevers are supported independently of each other by the supporting-bars, which extend in the plane of the table and are freely adjustable along the supporting rods of the frame, the supporting-barsbeing held by setscrews 38 in any position to which they may be adjusted, so that the spacing of the holes may be very readily changed, and said casings being detachably secured to the supportingbars when punches of a different size or kind are required or when they are not needed they may be quickly removed by loosening the bolts holding the wedge-blocks, removing the pin connecting the operating-levers with the punches, and slipping the casings laterally out of the channels in the bars. Any one of the punches may also be thrown out of operation by removing the pivot-pin 39, which secures the lever 13 to the post 32, and inserting this pin into holes 4C0, provided therefor in the side of the casing and punch-bar, the punch being thus locked within the casing and the lever allowed to rise and fall freely.
