PAPER'FASTENING DEVICE.
Original application filed February 4, 1924,.Seria1 No. 690,397, now Patent .No. 1,610,632, dated December 14, 1926. Divided and this application filed November 12, 1926. Serial No. 147,937.
This invention relates to improvements in paper fastening devices.
This ap )lication is a division of my application 'ior United States Letters Patent for paper fastening devices. Serial No. 690,397, filed February 4, 1924.
It is the primary objectof this invention to provide a novel and effective paper fastening device adapted to unite a multiplicity of sheets of paper by means of wire staples cut and formed by the machine in the couise of its operation.
More specifically stated. it is one of the objects of this invention to provide, in a desk machine of this character, a rctractible anvil over whichthe staple may be formed and which carries a portion of the wire feeding or :uilvancing mechanism whereby the retraction thereof. which is necessary to permit of a driving of the staples, may be uti lized in the engagement for advance of new lengths of wire into the machinery without additional motion transmitting linkage or other com licated mechanism.
It is a urther object of this invention to provide in compact form a machine of the character described in which the staple will be disposed transversely of the work. Various machines heretofore constructed have been designed to feed the staple to the work in such a manner that the staple will extend longitudinally thereof. but such a disposition of the staple has obvious disadvantages in that it does not bind sheets as firmly to gether as if the strain tending to separate such sheets were applied simultaneously to both legs of the staple. I am also aware that machines have been made to feed the staple transversely of the work but such machines have heretofore been awkward and bulky and it is one of the important objects of this invention to provide a machine in which the wire feeding and staple forming mechanism will be mounted in a narrow and compact form, the wire being preferably fed longitudinally of the work initially and then guided to move transverselythereof vast the staple forming die.

Like parts are identified by thesame reference characters throughout the several views.
In the principle of operation the deskdevice corresponds closely with the hand tool which has been described in the application hereinbefore referred to. Relative movement between parts is, however,.difierently produced in the desk device by reason of the fact that the hand supported tool previously disclosed makes use, in accomplishing its purposes, of structural features which are peculiar to the system of levers by means, of which the hand s'u1 )ported tool is ated.
The desk device comprises a flat base 10 having at its :torward end ananvil plate 11, and having at its rear end an arm 12 for the support of the spool 13. The spool may conveniently be provided with a peculiar support which comprises a sheet metal clip having upstanding ears Hand 15, portions of which are pressed inwardly to provide studs 16 for they rotatable mounting of spool 13. The base ofthe clip includes front and rear horizontal web portions 17 which pass beneath the arm 12 and an intermediate portion 18' which is pressed arcuately 11 wardly, whereby to permit arm '12 to be re- QP f tool may comprise a piece of sheet metal bent to form-a substantially tubular connectingportion20, spaced parallel plates 21 and 22,'and"outwardly turned flanges '23 connected respectively with said plates and restingiflat on base vlOi'or connection therewith. U-shaped plate 24 is likewise provided with out-turned flanges 25; for connection with the base member. 10' but is otherwise substantially identical withthe corresponding U- sha ed (1150, ose

in, the previously mentioned ap- T lte slz'de. v
The slide 2(l carries a guide tube 27 and,
at the rear end of said tube, a clutch device 28. Mandrel 29 is clearly shown in Fig ures 4 to 6, inclusive, corresponds in function, and in shape, to the mandrel 82 disclosed in the previously mentioned application,- although the specific form is slightly difl'erent.
Sliding actuating means.
Vertically reciprocable inthe. tubular portion 20 of the support is a jaw member ortubular plunger 30 whichis plugged at 31 andj 'cap1: ed with a button 32 secured to the plug by means of ascrew 33. Projecting rearwardly from said tube between plates 21 and 22 and rigidly connected with saidtube is an arm 34 which may take the .form of a plate. This arm is laterallyoli'set with the vertical axis of the tube in order to leave room for other elements hereinafter to he described.
lhe forming die corresponds closely to that disclosed. for the hand tool in theprevionsly mentioned application with the exception that it is diii erently actuated and is made substantially rectangular in its outline in orderthat it may be received and confined against lateral displacementwilbin the por tion 20 of thesupport. The forming die 41 is confined against longitudinal displace: ment by the walls of the sloth). it has spaced legs 42 and 43. The legs 42 and '43 are shown in Figure 7 to be provided with vertical grooves 44'. Le 4-3 is also guided with reference to the'U-siaped device 24 by means of the inwardly upsetears 45 as best shown in Figure 8. Resilient pressure behind the forming die is furnished by means of a spring 46 confined within the plunger 30.
The punch of staple driving member 4 7 is connected with the plunger 30 by means of alongitudinally extending pin 48 through which the movement of the plunger is trans mitted positively at all times to the staple drivingmember 47. The press is rccipro cable 1n the grooves 4-4 of thefornnng die member 41 when the. diemember moves with respect to 'the plunger, due to the yielding of spring 46. The rearward end of pin 48 extends through the wall of plunger 30 at an intermediate point in a vertically extending slot 49. which is best shown in Fi nre 10. The slot is of less widththan the diameter of pin 48 in order that the pin may find support in the wall of the plunger.
Reciprocable through slot 49 in a longitudinal direction is a slide which shows in planin Figure 1, and is shown in dotted lines in Figures 4 to 6, inclusive.
51 for bearing upon the upper. and lower surfaces 'of'pin 46. A finger 52 is integrally formed with the slide 50 and is bent at right angles laterally for the engagement oflhc cam surface 53 of the upright 36 which iscar ried by the slide. This upright also is pro vided with a flat spring 54 which, in the normal position of the parts, contacts with finger 52 to maintain the slide 50 in its innermost position. as indicated in Figure 4. The longitudinal reciprocation o'fslide 50 is further restricted in both directions through the provision therein of a slot 55 which receives the projecting axis pin of cam roller 35.
This slide comprises a thin,flat plate notched at The slide 50, while free to'move longieams:
tudinall can only move vertically in unison wi plunger 30. Its longitudinal reciprocation carries it to and from operative contact with the upper portion 56 of the forming die member 41. When the slide is in its forwardmost position, as indicated in Figure 4, it will transmit positively the movement of plunger 30 and pin 48 to the die member 41. When the slide 50 is in its retracted position, as indicated in Figure6, it will no longer contact with the die member 41, and the latter will be free to ride upwardly within the plunger 30 against the compression of spring 46.
Operation.
The operation of this embodiment of the invention is as follows.
The sheets of material to be secured together having been disposed upon the anvil 11, the operator will manually depress plunger 30 by the pressure of his hand upon the head 32 of said plunger. The infeeding of the wire stock will take place exactly in the manner already described in the previously mentioned application, and consequently will not be further mentioned at this point. The operating mechanism peculiar to this embodiment of the invention, however, will perhaps require further description.
As the plunger 30 moves downwardly it will compress the spring 38 which is later to restore it to its normal or original po' sition. During its initial movement the cam roller 35, which is rigidly connected therewith through the medium of arm 34, will move downwardly through the upper vertical position of cam slot 37. In. this portion ofthe slot the roller will obviously be productive of no effect upon the slide 26. During this period, when the slide is inoperative, the cutting and forming die 41 will be hearing, through its leg portions 42 and 43, u n the wire to sever therefrom a blank suit 1e for the staple forming operation.
As the downward movement of plunger 30 is continued, the cam roller 35 will ride on to the inclined portion of slot 37 and will commence the rearward reciprocation of slide 26. At the same time legs 42 and 43 of the forming die member arrangement is such that upon the completion of thestaple forming operation, and just about the time of the withdrawal of mandrel 29 from the staple, slide 50 will ride free of die member41. At about this time also the die member will contact with the paper sheets supported on anvil 11, and the plunger in its continued downward movement will begin to compress spring 46.
The relative movement is now occurring between the plunger 30 and the die member 41, whereby punch press 47, which is positively connected with the plunger, is having its extremity advanced toward the bottom of the die member whereby to expel from the grooves 44 the staple previously formed therein. This staple will be driven through the sheets 01' material to be fastened and will be clenched by anvil 11 in the manner. already described. of the parts at the time the staple is clenched is shown in Figure 6. I
Upon release of plunger 30 from manual pressure, the spring 38 will be adapted to restore all of the parts to their normal positions, as indicated in Figure 4. Plunger 30 will rise vertically,and the roller 35 of arm 34 will act uponan opposite side of the cam groove 37 to urge the slide 26 forwardly. The forming die 41 will remain in contact with the work until the compression of spring 46 is offset by contact of the forming die with the upper end of punch press 47. Thereafter, the slide 50 will be restored to its operative position about forming die 41 by means of spring 54. which will bear against finger 52. A new length of wire will meanwhile have been fed through tubular guide 27, in the manner already described with reference to the hand supported device disclosed in the previously mentioned application, and the tool is ready for a new paper fastening operation.
It will readily be seen that in the embodiment of this invention I have providec a novel andcomparatively simple mechanisu'l for the specified purposes. Attention is further called to the fact that while the dimensions of the tool are kept within small compass, as is desirable in a manually operable device of this character, nevertheless an arrangement has been perfected for feeding thewire transversely of the anvil. This is important for the reason that in legal docu ments it is very desirable to secure uniformity in the distance from the top of the sheets at which the staple is applied. If the staple were formed longitudinally of the machine, the machine would have to be applied to the sheet on a side margin thereof and the staple might be disposed at any distance from the top of the sheet. However, in the present device the staple is formed transversely of the machine and it becomes possible .to utilize the depth of recess 57 as. a
The ultimate positions positive guide for determiningtheulocationi: of each staple with reference to the top of the sheet; a A V,
,Nl hile practically any-kind orisize of wire may, be used indevices of this Character, I
have had particular success in theusc-v of a hard brass or bronze wire ranging in size from .01 ;to .016. Sue-h wire cuts readily under the degree of pressurewhich can .be

The brass or bronze wire cuts more easilythan iron or steel oflike diameter and has little, iiany, tendencyfto out or mutilate the-anvil and otheuworlzing parts of the device. Furtl1erm0re,ln'ass wire will notzrust and deface. paper secured by it as might be possible in the use of iron or steel wire.
It may be added further that if it be desired to cleneh the points of the staplein,
such a way that they will diverge instead ofconverge it is only necessary to eliminate grooves in the anvil or to substitute in member,said slide being retracted npon the downward movement of said member, a forming die guided for vertical movement and provided with a resiliently yieldable support from said member, said die including laterally spaced legs having extremities which, in the normally elevated posit-ion of said member, are spaced above a portion of said slide and are adapted to receive such portion between them prior to its retraction, and means for feeding wire transversely of said slide and positioning said wire in the advanced position of said slide beneath said legs to be acted on thereby.
