The ram sections are de? nitely spaced by having the lugs 91, which receive 35 the hinge tubes, ?t closely in between the hinge blocks 18. Set screws 98,. are shown for ?xing the ram sections, to the hinge tubes, so that the latter will pivot in the bearings provided in the hinge blocks. The hinge tubes, in more or less 40 close ?tting abutting engagement, Fig. 7, form a substantially continuous conduit and chamber for lubricant which may be supplied through an oil cup 99, or the like, Fig. 3, ?xed in one end tube, the opposite end tube being suitably closed as by a plug I88. Oil grooves I8I, may be cut in the abutting ends of the hinge tubes to admit lubri cant to the surrounding bearings in the interme-, diate blocks 18 and equivalent oil passages I82, Fig. '1, may be provided in the end hinge tubes for the outermost bearings 18. The bearing blocks 18 are shown in Fig. 6 as second side gage. The one way engagement at 68, ‘ keyed at I83, over the end of the rocker, so as to 18, between the ?rst side gage lever and the back 55 gage lever 31, with proper adjustment of the back gage, leaves this gage member with a certain freedom of action in the gaging direction, inde pendent of the ?rst lever. The springs which close the gage levers may be independently set to 30 properly cooperate in effecting the necessary in ter-relation and if desired, a certain independ ence of operation, such as described. The punch mechanism is operated from the same shaftwhich opens the gages. The cross shaft 56, whichgcarries the gage cam 55, at one end, carries at its opposite end a crank 13, ap proximately at the center of the machine, Fig. 1, with which is engaged a pitman 14, pivoted at its upper end at 15, to the longer, rearwardly 70 extending arm of a rocker 16. The pitman or crank rod 14, is shown as having an intermediate turnbuckle section 11; providing adjustment for locating the punch position as may be required. _ The forward'shorter arm of the/punch rocker 75 has secured to it a series of spaced pivot blocks be de?nitely ?xed and capable of carrying the punch load. Screws I84, secure them in this - keyed relation and enable quick and easy re moval. . The front ram guiding rollers 8| are shown in Figs. 6 and 8 as positioned in bearings I85, formed in the inner face of the removable front plate 9|, and the punch block locating bar 98, is illustrated as secured to the inner face of this front plate below these bearings. Angularly shaped guides I86, are shown as ad justably and removably secured by screws I81, Figs. 6 and '7, to the punch blocks in position to surely guide and strip the packs of sheets fed into the punches. The back guide roll 82 for the ram sections is indicated as journalled at its ends at I88, directly in the side‘ members I2. The shaft I89, on which the rocker is journalled is ?xedly mounted in these same side members. The rocker 16, is indicated in Figs. 3 and 6, as cham bered at II8, to hold lubricant for the bearing 3 2,114,259 portions of the same riding on the supporting shaft I09. ‘ The combined cam and crank shaft 56, is oper ated in the present disclosure from a short shaft III, Figs. 1 and 2, rimning from front to back of the machine and carrying a worm I I 2, in engage ment with a worm gear II3, on shaft 56. ,At'the front, the worm shaft is shown as having a pulley or series of pulleys Ill, for belt drive from the 10 motor “5,. and at the back this shaft carries a ?y wheel I I I5. The two angularly disposed shafts are indicated as both journalled in the same worm gear casing III, which thus affords bear-_ ing support and lubrication facilities for both 15 shafts. This arrangement is particularly com pact with the drive from one shaft to the other, intermediate the ends of the shafts and the ends of the ‘shafts exposed, the ?rst one to carry the belt pulley and fly wheel and the second?one to 20 carry the ram operating crank and the gage oper ating cam. A top board or plate I I8, is indicated as remov ably secured at “9, over the upper ends of the side members i2, as a cover for the rocker and 25 ram mechanism. The ready removability of this top board provides quick access to these parts for inspection or other purposes and, the removal of the front plate 9|, provides practically com ' plete access to all the punch mechanism. After 30 removal of the top member and loosening the formed by a continuous bar either ?xedly or adjustably secured at the back of the paper re ceiving groove 26, in the punchv heads or holders 25. Also the stripper may be a rigid piece secured in the top of the paper receiving recess, instead of an angularly bent piece of spring metal, such as indicated at I06, in Fig. 6. ,_At times, particularly for some special work, 10 it may be desirable to convert the machine from an automatic to a fixed gage press. This may be accomplished in the present disclosure by simply retracting one of the side gages and securing it in such retracted position, where it and the other 15 connected side gage and back gage will’ not be affected by the gage operating cam. In the construction illustrated, there is pro vided 'a shouldered hand screw I22, Fig. 3, which, after the left hand slide 29 has been retracted, 20 can be inserted through an opening I23, in that slide into a screw seat I24, in the table. In such ' position, this slide will be withdrawn beyond the extreme limit of retraction ordinarily accom plished by the cam and lever mechanism. Con 25 sequently, this and the other gage slides will stand still while the cam 55 and the lever 52 oscil lated thereby simply operate idly, the chain 50 permitting this idle oscillation. In order that the hand screw I22 be alwa 30 screws 92, clamping the punch blocks to the locate ing bar 90, the front panel SI, may be released available for the quick conversion of the machine from automatic to ?xed gage operation, the front and then lifted up from the punch blocks and ‘thus removed without disturbing the fastening panel SI is shown as having a screw seat I25, for this screw in position above the left hand gage 35. slide, so as to be‘ readily associated therewith. _ The securing of one gage slide, through the‘ 35 down of the punch blocks on the base. I The making of the ram in sections simpli?es manufacture, since these parts are usually of hardened steel. The same is true of the sectional pivot tube and the pivot blocks for the ram. interconnection of the slide operating levers at the underside of the table, effects the securing Grooves I2_I, Fig. 3, are shown'provided in the table top for receiving the ?ngers in picking the sheets up off the table. The back and side gages open far enough tofreely receive the sheet or group of. all three gage slides. Consequently any one or any combination of 40 the three gages may then be employed in using the machine, the gage or gages to be used being. secured in desired adjusted relation on its or of sheets forwhich theyhave been set and the'back their slide or slides. 45 gage quicklyadvances the sheet or sheetswhile the side- gages are registering and centering them.‘ By reason of this cooperative action, no special skill is required, it merely being necessary that the sheets be placed somewhere within the opened 50 back and side gages. The parts are timed so that the punch comes down immediately the sheets are located, thus providing maximum production. The operator merely has to lay the sheets within the open gages and then remove the punched ma The ?y wheel H6, at the back of the machine 45 may be used as a hand wheel for turning the machine over in making preliminary adjustments of the gages and other parts. Operation of the gages from the same mechanism which drives the punches assures proper cooperation and tim 50 ing and the structure is such that punches ‘and gages may be readily set for different desired operations. 7 - While the operation of the gages is- such as terial. These are safe, easy operations that can to require no special care, other than to place 55 be quickly performed._ The machine is particu! the sheets within the open gages, the combined operation of punch and gages is such that for . larly accurate because both side edges are gaged and because the gages yieldingly “feel” and “square up” the edges of the stack through the ~60 medium of the gage closing springs. The posi tive motion of the cam opens the gages and the the most e?icient results the operator should have in convenient reach a stack of sheets to be punched and, in equally convenient position, a holder to receive the punched sheets. .Ac parts preferably are set so that the cam will not cordingly, the machine is preferably equipped, delay or impede the gage closing movements e?ected by the springs. Non-interference of this as indicated particularly in Figs. v1 and 3, with sort may be assured by actually having a certain amount of slack 'irnrthe gage opening" chain 50, in the gaging position of the parts, substantially as indicated inFig. 1. ‘ - The front of the hollow base is shown as having 70 a hinged door I20, providing ready access for belt changing or other-purposes. If'desired, the back of thebase may be closed in to cover the rocker and the crank and cam mechanisms. Many >,other changes may be made-all within the true 75 scope of the following claims. Thus instead of , the row of pins 24, the front gage may be ' spirit of theinvention and ‘within the broad a so-called “stacker” I26, at the right hand side of the feed table II, for holding a supply of 65 sheets in orderly arrangement to be ‘quickly grasped by one hand and a receiving stacker I21, at the opposite'side of the table in position to hold and stack the sheets which have been punched. ‘ 70 These supply and receiving stackers are‘mount ed soas not to interfere with the operations of the gages and this is accomplished in the ‘ present disclosure by securing them on clamps I28, I29, slotted at I", to ?t over the opposite 75 4 2,114,259 edges of the table and provided with screws I3I, by which they may be held in variously adjusted relation to said actuating means, a readily re ticularly in Fig. 1, the body portions of these clamps are high enough to support the stackers movable member for holding the gage stationary and separated from said actuating means, said member being removably ‘associated with said ‘gage and a support for said removable member above the level of the gages, so as not to inter fere with the operation of the gages even in the adjacent said table for holding said member when not in service in readily accessible position, angular relations on the table. As shown par maximum opening adjustments of the latter. By preference, the stackers are open sided 10 boxes, such as illustrated, having ?at bottoms I32, and two angularly related back and end walls I33, I34, arranged as in Fig. '3, on con vergent inclines toward the punch head and with the open front and outer ends toward the 15 operator who ordinarily is stationed directly in front of the table in-line with the gages. To aid the operator in grasping the top sheets without disturbing the rest of the stack, the sup ply stacker may be constructed with‘ the back 20 wall I33, inclined forwardly, so as.to offset the top of the stack toward the operator, substan tially as indicated. This arrangement also ena bles the operator to readily and quickly select the desired number of sheets for each punch 25 operation. Also as indicated in Fig. 3, the end wall I34, of the ‘feed or supply stacker need not be full length, to give greater clearance for the quick removal of the sheets'from the top of. the stack. This same construction may be followed in the receiving stacker. The clamp constructions permit the stackers to be quickly removed and replaced and enable either one or both stackers to be readily set at di?erent angles and ‘in different positions on the table to best suit a. particular operator and in accordance with size of sheets, etc. ' This arrangement of supply stacker at one side of the gages and receiving stacker at the opposite side, enables an operator to quickly remove the desired number of sheets and place them within the gages, with one hand, and then with the other hand to pick up the punched sheets and lay them in reversed order in the receiving stack er, thus keeping the sheets in the original order. 45 In the receiving stacker they may be quickly trued up at any time by simply pressing on the exposed corner of the stack in that holder.
