This invention relates to machines for perforating, and at thesame time securing toher several thicknesses of paper, fastenmgs being passed through and clinched in the paper, near the edges thereof, while the perforations are made near the latter, in order to provide for the removal ofthe secured to ther edges to facilitate the separation oftfii thicknesses'of paper, or the open- 1. in out of the latter from a folded form.

1 achines for perforating sheets of paper and for securin same together have been made in various orms, and the object of this invention is to provide an improved construction of machine, by means of whichthickmesses of paper, may be securely fastened togather at their edges and at thesame time be perforated near the latter, during the one and the same operation, which also provides for a suppl of'the fasteners used for securing the thic sses together being maintained in pro-determined numbers, regulatable at will. i

The improved machine comprises a sloping 7 holder for the paper fasteners; means for agitating the contents of the holder, movable and fixed dies for forcing the fasteners through the paper and clinching them there in; raceways for leading the fasteners from the holder to between the dies. a shutter for controlling the delivery of fasteners from the r ceways, means foroontrolling and regulating the passage of fasteners down the raceways; and means operable from the movable die actuating means for effecting the agitation ofthe fasteners in their holder.

The means for controlling the delivery of the fasteners from the raceways in order to provide for the securing of the paper edges at one or more points, consists of a shutter adjustable across the raceways, and containing openings disposed so that one, two or three raceways may be opened at anyone time, whereby a single, ortwo or three fastenors can be passed at a time to between the dies for insertion in the paper.

The means for controlling and regulating the passa of the fasteners down the raceways, so 1: at not more than a single fastener can escape at any one time from each raceway, comprises pins, a lower andan upper pin to each raceway, actuated from a rocking plate so that upon the lower pin releasing a fastener for delivery to between the dies, the remainder of the fasteners in the same raceway are held by the upper pin until such time as the lower pin is again inserted in the raceway, when the fasteners in the raceway gravitate down to the lower in.

a The raceways are kept filled wit 1 fasteners, from the holder, to ensure a regular supply of fasteners to between the dies as required, by means of an agitator, operating in the holder, to pass fasteners from the latter,to an annular channel from which said fasteners are passed to the raceways, said agitator being operated from the die actuatin means so that each time the machine is used to perforate and to fasten thicknesses of pa 1' together, the agitator is given motion, tiereby ensuring a regular supply of fasteners to the raceways.

The above and other features comprised in the invention will however be more particularly described with the aid of the accompanying drawings, which illustrate a machine suitabic for inserting eyelets in and also for perforating thicknesses of paper.

The machine comprises a holder 1 for paper fasteners such as eyelets,supported be tween the side plates 2, rising from a base plate 3, so that its bottom slopes downwards towards the front of the machine, said holder being provided with a cover 1a removable perspective of at will. a

A spindle 24 passing through the holder 1 has keyed thereon within said holder, an agitator, 6 fitted with brushes 7 adapted to sweep against the inner surface of the wall of the holder 1, upon the spindle 41 being rotated,nwhile the portion of the lattenlJQ- tween the bearings '5 has keyed thereon a cured together is formed of spring material and as attached to the die block -23,- by por drum 8.

f Acord- 9 passed one or 'more times around the drum 8, is led around guide-pulleys 9a one on each side plate2, the ends of said cord being passed one" end above and one end below the opposite ends of a horizontal spindle 10 supported by bearings 11 on the side 'plates 2, across the fro'nt'of the machine, the ends of said cord 9 being secured to said spindle 10 by screws 27 i e A hand lever 12 fixed on one end of the spindle 10 is provided to enable the latter to be given partial turning movement in either-direction, turning movement of said spindle in either direction, winding'in one end of the cord 9 and unwinding the other end thereof whereby the spindle 4 and agitator 6 with the brushes 7 are caused to be rotated within the holder 1. The wallof the holder 1 contains openings 13 which lead into an annular channel 17 surrounding saidholder, the bottom of the channel 17 having recessed therein a ring 14 to; which is, connected by a pin 15 the outer end of an arm 16 keyed on the spindle 4, the pin, 15 passing through a curved. slot 15a in the base of the holder 1 so that when the agitator 6 is given turning movement in the holder 1 the ring 14 is alsogiven turning movement in the channel 17 x Inclining downwards from the lower or front portion ofthe annular channel .17 to a guide block 18 at the front of the machine are raceways 19, the internal cross dimension of each of which is such that eyelets can pass down the same only in single file.

The guide block 18 is kept pressed up against the lower ends of the ,raceways 19 and out ofthe' recess 18a by'springs 20 in compression between the'base plate3 and said blockv18', vpins 20a .around which the springs 20 are placed being securedtothe base plate 3, and being entered in the guide block 18' to act as guides for the'lattergduring upwards and downwards movement thereof, A blade 28 with a serrated upper cutting edge 28a is securedto the base plate 3 at the outer edge of the guide block 18, the latter when forced down, passing below the serrations 28a. V The rac'eways 19 lead to openings 19min the guide. block 18, lower dies 21 secured to the base plate 3, being located immediately below said openings 19a, while 11131361" dies 22 one directly over'each lower die 21, are carriedby a die bloclr23, mounted across the outer ends of arms 24 pivoted to the base plate 3 at 24a, and connectedby a cross bar25,

between which and said base plate 3 a spring 26, in compression acts to maintain the die block 23 normally up against the intermediate eccentric portion 10a, which is mounted onthehorizontal cross spindle 10, e .1

A rest plate 29 for the thiclinesses"ofpaper or other material to be perforated and setions'29a atits ends, said plate 29 not extending over the blade 28 or the lower dies 21. The means for controlling and regulating the passage of eyelets down the raceways 19 to the openings 19a in the guide block 18 comprises

pins

30, 31 passing "upwards through the 'raceways19 there beingan; upper pin 30 and a 'lowerpin 31 to each ra ce '19,the

pins

30, 31 having thereon springs 32 adapted to be compressed between their heads andthe raceways 19 the former bearing 'onfa rocking plate 33 mountedbetween the side plates 2. i The spindle 34onwhiehthe'plate 33 is secured extends through-the side plates 2 and has secured on one end putside the adjacent side plate 2 an arm 35 betweenthe outer endof which and a pin on saidside ,plate 2 a tension spring '36 acts to normally tend to move the rocking plate 33 from the position shown in the drawing, said; plate 33 being maintained in; the position shown against the action of the spring 36 by the engagement of the pawl 37xkeyed on the shaft 38,-in the notch 39a of the disc 39 keyed on the opposite end of the spindle 34, to the arm 35, and also outside the adjacent side plate 2." r

The disc 39 is adaptedto be freed of the pawl 37 a to enable the plate 33 to move under the action of the spring 36, by an arm 40 fixed on the end of the horizontal spindle 10 engaging (and afterwards clearing). a further short arm 41 on; the shaft 38 where bypartial turning movement is given the latter and to withdraw the pawl 37 fromthe notch 39 of the disc 39, against the-action of atension spring '42 acting between said pawl 37 and a pin on theiside, plate 2..

The arm 41 is mounted on the shaft 38 so that when moved by the arm 40 asthehand lever 12 is'brought to the front of-the machine, it, the arm 41 imparts turning movement to theshaft138, said arm41 however being free to turn in the reverse direction on the shaft 38, without aiiecting the latter, and against theaction of thespring 41a;

Means for cutting ie'if the supply, or feed of eyelets down the raceways 19, comprises a shutter 43 operable horizontally through the side plates, 2 and also through slots 44 in the sides of said raceways, said shutter 43 having a tongue .45 and openings the shutter 43 for the purpose of being en gagedby a regulatable spring pressed ball 49 held in a casing 50 on a side plate 2, so as to maintain the shutter 43 in a selected position. a 1 In the drawing the shutter 43 is shown with the tongue 45 in the centre raceway 19 and with the openings 47 extending across the side. raceways 19, and in this position eyelets can not pass down the centre raceway 19, but are able to pass down the two sideraceways 19. If the shutter 43 be moved from right to left a distance equal to the dis.- tance between two of the recesses .or depressions 48, the tongue 45 will be moved out of the centre raceway 19 to open same, while the openings 47 will still allow eyelets to pass down the two side raceways 19, so that all three raceways 19 will be open for the passage of eyelets down same. If the shutter be. given additional movement in the same direction the additional movement being also equal to the distance betweentwo of the recesses or depressions 48, it will be seen that all of the

openings

46 and 47 will clear the raceways 19, and the latter will all be closed by the shutter 43 to the passage of eyelets down same. Withthe shutter 43 in the position shown movement of the latter from left to right, a distance equal to the distance between two of the recesses or depressions 48 will have the effect of moving the tongue 45 out of the centre raceway 19 and at the same time of closing the side r-aceways 19, thereby leaving the centre raceway 19 open for the passageof eyelets down same.

Thus it will be seen that-with the check ball 49 engaged in the recess or depression 48 marked 1 on the shutter 43, the latter will open only the centre raceway 19, and with the ball 49 engaged in recess or depression 48 marked 2 the two side raceways 19 only will be opened, and with the ball 49 engaged in recess or depression 48 marked 3 all three raceways 19 will be opened while with the ball 49 engaged in recess or depression 48 marked a all three raceways will be closed, so that the operator is enabled to allow 011e, two or three eyelets to pass to the dies as he desires, or is enabled to cut oil the feed of eyelets altogether. Screws 51 adjustable through the arms 24 are provided to engage downwardly bent portions 52 of the plate 33, as said arms are moved downwards, for the purpose of bringing said plate 33 and the pins 31 to the positions shown in the drawing as will be hereinafter described.

To operate the machine the procedure is as follows :The eyelets are placed in the holder 1, and the shutter 43 adjusted to close all of the raceways 19. The hand lever 12 is then worked from back to front of the machine and Vice versa to rotate through the 65 cord 9, the agitator 6 and the ring 14, the

brushes 7. feeding the eyelets through the openings 13 inthe holder 1, into the annular channel 17 and onto the ring 14, the latter agitating the eyelets so that they feed down to the raceways 19, guard plates 54 preventing said eyelets jumping from the raceways 19 as they enter same.

When the raceways 19 are fully charged the shutter 43 is adjusted to allow eyelets from one, two or three raceways 19 topass to between the

dies

21, 22 according to re quireinents, there being a pair of dies for each raceway.

The thicknesses of pa er or other material to be fastened together and perforated are inserted between the rest plate 29 and the upperdies 22 and the hand lever 12 swung from the back to the front of the machine, the rocking plate 33 being at this time in the position shown in the drawing with the lower pins 31 projecting up one into each racewa 19, the upper pins 30 all being withdrawn from the latter.

During the first portion of the forward movement of the hand lever 12, the arm 40, on the horizontal spindle 10 engages the arm 41 on the shaft 38 and turns the latter to withdraw the pawl 37 from the notch 39a in the disc 39, immediately following which the spring 36 acts on the arm to rock the plate 33 on its spindle 34 so that the lower pins 31 will withdraw from the raceways 19 and the upper pins 30 will extend thereinto to engage in the second lowermost eyelets, the lowermost of which in each raceway 19 at the time in use upon being released by the pins 31 gravitate down the raceways 19 onto the lower dies 21 in the openings 19a in the guide block 18, the upper pins 30 preventing more than one eyelet escaping at a time from each raceway.

Continued forward movement of the hand lever 12 brings the eccentric portion 10a of the horizontal spindle 10 into action on the top of the upper die block 23 forcing the same, and the rest plate 29 down into contact with the guide block 18, the latter owing to its support by the springs 20 yielding until it contacts with the base 3 in which osition it is below the serrated ed e 28a 0 the blade 28, whereupon the rest p ate 29 yields under the action of the downwardly moving die block 23 and the eyelets on the lower dies 21 are clinched between the latter and the upper dies 22 and through the paper or other material, the serrated edge 28a of the blade 28 at the same time piercing th8 Paper or other material and forming a line of perforations therein, a strip of soft material being provided on the die block 23, imme-v diatelylover the blade 28 to prevent damage to the serrated edge or teeth thereof,

During the latter portion of the forward movement of the hand lever 12 the screws 51 in the arms 24 engage the downturned por tions 52 of the plate 33 and force'the latter against the action of the spring36 back. to: its original positionas. shown in the drawing, the disc 39 being turned; so that the pawl 37. will snap intothe notch 39aunderthe action of the spring 42 and so lock. the plate 33 until the next time the hand lever 12, is swung forward. 1

.The return of the plate 33 to its original position has the .efiect of re-inserting the pins 31 in the raceways 1 9 and of withdrawing the pins 30, which have in the meantime been keeping the. eyelets remaining in the racewaysfrom. slidingdown the latter, the withdrawal of .saidpins allowing the'eyelets to .move down against the pins '31, in readiness for the lowermost eyelets to be released for the .nextpaper securing or sealing operation.

The hand lever 12 is now returned from the front to the back of the machine, and the secured together thicknesses of paper or other material withdrawn from between the I die block 23 being raised by the .arms 241m:

der the action of the spring 26, as the latter returnssaid arms and die block to their original positions. 1

-.Dur1ng .the return-of the hand lever 12 A from the front to the rear of the machine, the

arm 40, which is now on the reverse side of the arm ll to that shown in the drawing engages the latter, said armdl however merely turning idly on the shaft 38, until cleared by the arm 40, whereupon the springs 41a returns the arm 41 to the position shown in the drawing, in readiness for causing the withdrawal of the pawl 37 from the disc 39 upon I the next forward stroke of the handlever12.

As each stroke of the hand lever 12 causes the operation of the agitator 6 and the ring 14 eyelets are'fed at each operationof the machine, to the raceways 19 in order to keep samefull. v v
