Application led .Tune 28,

This invention relates to a punch which is useful particularly to punch holes in sheets of paper at spaced apart points so that the same may be engaged with binding posts of binders in which they aretobe bound which may be engaged with posts or other devices for the purpose of holding the sheets against misplacement or the like. i

The Apresent inventionis directed to means for gauging the sheets of paper so as to properly locate the holes which are to be punched therein. This requires gauges at two edges of the sheet so as to accurately locate the holes f and these gauges must be adjustable for different `sizes of ,sheets which may be punched in the device. It is a primary object and purpose of the present invention to provide simple, practical and very easily adjusted gauges of the kind specified `and which can be very readily manufactured and installedin a machine. To these ends, aswell as to others not at this time specifically stated, I have devised the construction described in the `following description and shown `in the accompanying' drawings, in which f Fig. l is ahorizontal sectional and plan view of the punchequipped with the gauge devices of myinvention.Y i

Fig.` 2 is a front elevation of the punch, one vpart thereof being shown in section for betterillustration of the construction.

Fig. 3 is a viewsimilar to Fig. 2 except that the forwardly extending lower `portion of thepunch is shown in horizontal section.

AFigs. 4 and 5 are vertical sections taken substantially on the planesof lines 4-4 and `.5f-5 of Fig. 3, and i 'i Fig. .6 is lan under plan view of` the re taining device for each of the punchingrods, the rod itself being shown in horizontal section. o

Like reference characters refer to like parts inthe different figures of the drawings.

i Inithe construction of the punch, a supporting base lof somewhatelongated form is provided integral with-which is fa vertical back 2 extending upwardly froml the base for a distance. The base is located a short distance above the desk orcounter on which it. is supported, and has downwardly turned flanges at its rear side land ends which at the corners are formed into feet` indicated at 3. A longitudinal slot el is made inthe vscrews or like suitable fastenings, the rear rUNCH-GAUGING MEANS.`

base nearly from one end thereof to the other a short distance in front of the back 2 described. `On the `basen` table 5 of sheet metal is permanently secured by means of edge of which is a short distance in front of rthe front side `of the slot 4 While `its front .edge projects somewhat in `front of the supporting basel. The plate 5 is longitudinally slotted from one end inwardly substantially one third or more of its length, as indicatedat 6, underneath which alongitudinal slotted `gauge bar 7 is mounted for adjustment being received in a groove 6 made theentire length of and inthe u per side of the base 1, as shown in Fig. 3. aid groove issomewhat` wider than the width of theslot 6. The outer end of the bar 7 is turned upwardly at right angles making the lip 8, best shown in Figs. 2 and 3. i

Atthe inner end of the slot 6 a substantially square enlargement is made in table 5. A threaded bolt 9 `having a square head l0 passes downwardly throughthe slot in the gauge bar 7 .y theisquare head` 10 lying in the square opening described with its .upperside flush with the upper side ofthe 4table 5. A nut 11 `is threaded` onto the lower end of the bolt `9 `and is provided with anoutwardly extending rod orihandle l2 so that it may be turned from in frontV to secure the gauge bar 6 in any position to which it may be adjusted. It is evident i that by turning the handle`12, as shown in Fig. 1, in a counter clockwise direction the nut may be loosened and the bar 7 may be moved inwardly or outwardly as far as vdesired and then by merely moving the handle 12 in the opposite direction the gauge bar will be securely held in place. This adjustment is accomplished very easily and. almost instantly and paper placed over the table 5 will have one edge thereof brought against the upturned lip 8; and each sheet Vof paperplaced inthe punch will be loi cated withreference to the punch at exactly the same place so far as said edge of the sheet 'is concerned, as long as the osition of the gauge bar 7 `remains unc anged. For .different sizes of sheets of paper the i gauge bar may be adjusted, but remaining fixed-in one position for sheets of the same slze. i A

The base 1 at the front edge of the elongated slot 4'` therein is rabbetedproviding a vertical elongated shoulder 13. Guide blocks 14 for the punches are located over the slot 4 in spaced apartv relation and at theirfront. lower corners bear against saidY shoulder 13. Each ot'these blocks is formed with a. horizontal slot 15 at its front, the lower side of which is in the same plane with the upper side of the table 5.', A. sheet of paper placed over thev table may be inserted into the slot-S15 ofi the blocks 14. These blocksare also'lornied with vertical cylindrical openings 16 therethrough for guidance of the punchesused therewith as later described.l As many ofl these guide blocks `may be usedE as desired, there being two located at spaced apart` points shown inthe drawings. Inadditionto the punch guide blocks 14 gauge blocks 17 arey likewise located over the slot 4, their front ends bearing against the-shoulderl-lin the same way'that the guide blocksA 14 bear and' their rear ends being disposed in the same vertical plate with the rear sides of the blocks 14. These gauge blocks 17 are slotted horiL zontally from their front ends back nearly to theirrear ends and the lower sides of said slots, indicated at 18, are likewise in the-same plane with the upper side of the table 5. Blocks 17 'are also interiorly bored and threaded so as to receive gauge screws 19v which may be adjusted to any desired positionl inthe length of' the gauge blocks 17 and againstv which the edge of the paper K inserted intothe slots 15' and 1S will engage A so as to stop the= sheeti of paper at a: predetermined position` This is.` indicated in Fig. 4 wherein the sheet. of paper S placed over thel table 5 atits rear edge is shown as abutting against the front end of' the gauge screw 19.

The punch blocks 14 and the gauge blocks 17 are all heldin place by a presser bar 2() bearing against the rear sides of said blocks and pressed thereagainst by set screws 22 which thread through the back 2.' The presser har 2O at each end is equipped with af. pin 21 which is received in a suitable guide opening in the back 2iso as to properly locate the same. At any time it is desired to change the position of the guide and gauge blocksit isnecessary merely to loosen the screws22 whereupon the blocks 14 or 17 may be moved tothe positions desired.

Directly over thefpunch guide blocks 14 is a punching head 23 formed at its front and: rear sides with elongated horizontal grooves 24 for the slidable connection of punch Carryingmembers 25, the same being formed' of'sheet metall and of substantially channelformhavingithe edges-of the Hanges turnedinwardly, as indicated at 26, to slidably tit the grooves 24. The under face oeach member 25' is pressed downwardly forming the embossing 25a which is provided with. av key hole; slot 27. The punch is a cylindrical. rod 28 having: an enlarged Hat head 29 which may be readily connected with or disconnected fromV the member 25 through the mediumY of the Vkey hole slot described and l'ully shown in Fig. 6; The punches 28 pass downwardly into the openings 1G through the blocks 14 and are guided therein in their up and down movements.

The back 2 midway between its ends is extended outwardly and formed as avertical guide 3() in which a vertical stem 315 attached to or formed integral with' the; punching head 23 is slidably mounted. This; part 31 has an openingY 32.tln:oughwit. A handle 33k is pivotally mounted to turn aboutl the axis of' the pin 341associated-with which is an eccentric 35 received-inthe opening'32, it being evident that on turning the handle-in onedirection-the head 231 with the punches 2S connected thereto is moved downwardly so that saidpunchespassfaercss the slots 15 in blocks14 and perforate any sheet S which may. be located in the slots 15. By reason et the loose connectionof'the members 25 to the head23, said members l witlrthe attached punches 28 may be movedV and readily adjusted at the sameV time the guide blocks 14 are adjusted.:v

A sheet ot paperrindicated at S in. Figs. 4 and 5, when `placed in thel devicev for punching is brought against the fronti ends ofthe gauge screws 19 andiat` anouten edge against the lip 8 on the gauge bar/7. rPhis properly locates the sheet andthen byfoperating the handle 33 the holes-.desiredinvthe y sheet are readily punched. The gauge bar 7, as previously described, may be changed in position very quickly andeasily and it is also evident that'the gauge' screws: 19 maybe very quickly and.y easily changed being moved inward or outward asfV desired. This makes the punch adaptablefrumany different sizes of sheetsof paper-whichare to be punched. It the gauges are setfor one size, every sheet of the size punched will have openingsmade thereiniwhich when all of the sheets are placed together., will align v so as to rreadily pass over binding: posts and the edges of all the sheets willibe'ueven. The invention described is very` practical and simple, is economicallymanufactured and is sure and efficient in its operation. The invention is defined inthe appended claims and is to-beV considered' comprehensive of all forms of structure comingJwithin their scope.
