Fig. 13 is a fragmentary view of the pan or receptacle.

Illustrative of the embodiment disclosed, the perforating device is generally designated P and is characterized by a base B, stanchions or brackets S, the pivoted handle H, the slidable graduated paper guide G, guide release and locking means R, the fixed punch bearings B, punch lifters or carriers C, cutting tools or punches T, and the slidable collecting receptacle or dish D.

The base B is of sturdy sheet metal and em bodies a seat or top wall W for supporting the sheets to be perforated and is provided with the peripheral rim l0 depending from the sides and front end thereof. Extending inwardly of the sides ll of rim Ill at the rear parts of the latter are the flanges or rails I2 having secured thereto rubber feet l3. Lugs l4 extending inwardly of the front end I5 of the rim in also carry rubber feet l3. These feet l3 support the base to prevent scratching or marring in shifting of the perforating device from place to place on a supporting surface.

Spaced sides I I together with the inwardly turned flanges 0r rails I2 constitute means for desirably and slidably retaining the pan or receptacle D underneath the top wall W of the base whereby the inclined portion or chute [6 will be in alinement or under the relatively large elliptically shaped openings I! in the spaced depressed portions or indents l8 in the supporting wall W but only at a time when lip I9 is received in the reentrant stop notch 20 at the rear of top wall W. Thus suitable stop means are provided and come into play on the complete closing of the receptacle and where it is desired to withdraw the receptacle lip l9 may be utilized as a manipulator for this purpose.

Struck out of the base of wall W but outwardly thereof are the spaced bosses 2| which are directly to the rear of the spaced indents l8 and fixedly seated on theses bosses are the stanchions or standards S which are also of suitable sheet metal. Intervening the indents l8 and the bosses 2| are the spaced gaps 22 whereby during assembly front portions of the die plates 23 may be quickly inserted through the transverse gaps 22 and onto the indents I! to be positioned automatically by the walls of the latter to place the forward cutting perforations 24 of the die plates in alinement with the ejecting openings l1 and simultaneously positioning the rear portions of the die plates 23 under and against the bottom faces of bosses 2|.

Each stanchion S is a channel shaped member comprising a bottom wall 23 and upstanding and spaced side walls 28 folded inwardly to define alined meeting flanges 21 characterizing a front fall 28. The stanchions characterize means for automatically positioning the looped shaped guide bearings B whereby the tool guide openings 29 and 30 in the loop portion L of each bearing B are in alinement with the cutting openings 24 in the relatively hard steel die plates 23, that is, upon insertion of the bearing B in the stanchions (Fig. 5), walls 28 locate the guide bearings B transversely thereof and front walls 28 limit forward insertion thereof at which time the tool guide openings 29 and 30 in the loops of the bearings B are in alinement with the front cutting openings 24 of the die plates 23 and the spaced openings 3| and 32 of the superimposed arm 33 and 34 of the loops B are in registration with the spaced openings 35 in the bottom wall 25 of the stanchions S and with the spaced open- 1118s 38 in the spaced bosses 2| and with the spaced openings 31 in the die plates By reason or this structure the bearings B may he quickly assembled in the stanchicns and readily secured to each other and to the bosses and die plates by the anchoring rivets 88.

Associated with each oi the stanchions S and slidably and reciprocahly guided therein is the tool lifter or carrier C each of which comprises a U shaped metal member All having its upper and lower legs 45 and 52 provided with a slot m it and the slots of the lower legs '52 closely but removably and selectively receive the reduced rooved portion 44 of steel cutting tools or punches T. Thus the latter are removably inter= locked with the channel shaped slidable carriers or lifters C and consequently it the latter are reciprocatcd, punches T will be correspondingly actuated and slidahly guided in alined openings 29 and 3d of the upper and lower portions 55 and 4B of the respective loops L of the fixed and spaced bearings B which project slightly below the front walls 28 of the stanchions S and into bot tom openings or cutaway portions M in the bottom walls 25 thereof.

Pivotally straddling sides 26 of the fixed but spaced stanchions S are the depending ears d8 of the spaced channeled arms Ml oi the handle H. Specifically however these lugs or ears d8 are pivotally or rotatably mounted on the fixed fulcrum pins 50 carried by the spaced sides 26 of the spaced stanchions S and encircling each of the fulcrum pins 50 is a helicoidal spring Eli having one end 52 anchored under a lug 53 at tached to corresponding side walls 26 of the stanchions and having a free end 5c contlnu-y ously abutting the respective arms 49 of the loandle to movably hold the latter elevated or raised at which time the spaced cutting tools I are held raised simultaneously to permit insertion of paper or the like into the spaced receiving gaps 55 between the spaced fixed loops L and the front exposed portions of the die plates 23.

Reciprocably guided by the spaced stanchions S are the spaced pins 56 fixedly carried by the depending ears 48 of the arms 49 of the pivoted handle H and closely surrounding each pin 56 is a sleeve 5'! interposed between a pair of sides 2-6 of the stanchions, each pin 56 being reciprocably guided in spaced and vertically disposed and transversely alined slots 58 in the side walls 2B of each stanchion. It therefore the handle H is depressed against the resistance of springs 5|, pins 56 move downwardly simultaneously relative to the stanchions and hence the sleeves 51 acting on heads 59 of the cutting tools T move raised and thus the perforating punches T are free and clear of the article receiving gaps 55.

According to the invention the release mechanism R in the form of a lock is automatically effective pursuant to the proper positioning oi.

the slidable paper gage G. This release mecha- 7 nism comprises a steel leaf spring 60 having one end 6| secured to spacing elements 62 and to the top wall W of the base by rivets B3. The intermediate portion of leaf spring 60 carries a fixed button 64 normally disposed in the annular collar 65 struck out of the base. The free end (56 of leaf spring fill has a fixed detent 6i slidably fitting into opening 68 (Fig. 9) of guide seat 6i) and into opening lit or the spring saddle ll and selectively into the openings as l2 of the graduated bar 713 of the gag G slldably guided by the alined slots it at the sides of the base.

The saddle ii is of relatively thin spring metal having curved sides Bil straddling gag seat E39 and characterizes means to take up the slack between the sage and wall W of the base and to hold the gage frictlonally against the bottom wall W during the locking relation of the release mechanism. Thus by the present arrangement, the gage bar G may be readily adjustw widthwise of the base by first depressing button 64 to free the detent till oi the gage at which time with the aid of manipulator til, the bar may be slidably and easily moved widthwise of the base. Following this operation and ii. finger pressure is removed from the depressible button 64, detent i371 automatically interlocks with one of the notches T12 of the graduated bar, and as is well understood manipulator ill also serves to position the paper for punching. Where however the bar is set as to dispose th locking detent El between a pair of perforations 72, the inherent resiliency of crown portion l i of spring metal saddie ll frlctionally holds the bar against the wall W in desired set position.

The punches T are hardened tool steel and are carried on the downward stroke of the pivoted handle to be driven downwardly by the freely rotatable hardened metal sleeves or bushings 5i closely surrounding the reciprocably but vertically guided pins 55, the sleeves preventing buckling of the slidable pins 56 and reinforce the latter. Following the punching operation, the handle automatically retracts to its raised position (Fig. 6) due to the action of spring 59 and during such action pins 56 are raised, hence raising the rotatable sleeves El and the latter elevate the couplings or links or lifters C, thus elevating the cutting tools T.

As previously pointed out the die lates 23 are prehardened steel and during assembly may be quickly arranged for relatively narrow or wide punching. In this connection it will be observed that cutting perforations 24 are disposed to one side of the longitudinal axis of die plates 23 along the inner margins thereof for narrow gage punching and are arranged as shown in Figs. 7 and 12. Where however, wide gage punching is desired these die plate are turned over to present the cutting perforations 24 along the outer margins of the die plates as illustrated in Fig. 11. However following the positioning of the die plates for either narrow or wide punching, they are firmly anchored as previously explained and as far as the slidable receptacle or pan D is concerned it is of a suitable spring metal having its sides slotted at to enhance its resiliency and bowed or crimped outwardly at 9! to frictionally cooperate with sides H of the base.

Where the die plates are positioned for narrow gage punching, the tool lifters are correspondingly positioned, to wit, the alined perforations 43 thereof are disposed inwardly of the vertical axis thereof and in case wide gage punchings are desired the tool lifters are reversed to present the alined perforations outwardly of the vertical axis of the lifters.

Having set forth the details of the invention, the objects and advantages, inter alia, thereof, may be considered as follows: the provision of a durable and sturdy perforating device for punching relatively thick stacks of paper or the like with ease, the provision of spaced and reciprocabiy guided cutting tool lifters or links effective upon the return of the pivoted handle pursuant to removal of manual pressure thereon to retract the cutting tools from the paper receiving gaps due to the automatic action of spaced coiled springs; the provision of a slidably guided paper gage having means for looking the gage in predetermined positions of selections, the provisions of loop shaped and fixed bearings for reciprocabiy guiding spaced cutting tools or punches; the provision of channel shaped stanchions or brackets for automatically positioning the loop shaped guide bearings, the provision of a receptacle disposed under and common to the spaced die plates and having chute means in alinement with paper ejecting openings in the base and die plates when the receptacle is fully closed, the provision of interchangeable die plates and lifters for perforating for predetermined positions of selections, and provision of means for conveniently raising the pivoted handle even though the punching tools thereof have penetrated a large bulk ofpaper in that springs automatically raise the handle, and the latter carries reciprocable pins upwardly and hence, reinforcing sleeves about the pins are elevated thus retracting the slidably guided tool lifters which may be considered as coupling or link means.

Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages thereof inherent therein.
