To all whom it may concern: I

Be it known that I, lVILLnRD EL SWIFT, a citizen of the United States, residing at Worcester, inthe countv of \Vorce'ster and Commonwealth of Massachusetts, have in- 7 body of the envelop are provided with cirwork of the machine, which supports the Sim 1ar vpartsgnnthe different figures.

cular washers or disks, attached thereto by eyelets; to one of these disks a cord or string is attached, with its free end adapted to be wound successively around the tWo eyelets and beneath the disks, thereby securely uniting the seal flap and body of the envelop. I

The invention consists in providing in a single machine instrumentalities for punching" out the Washers or disks successively from a continuous strip of material, and for attaching each such Washer by means of an eyelet'to the seal flap or the body of the envelop, whichever is presented to the attaching mechanism by the operator. The invention further consists in the construction and arrangement of parts whereby these results are accomplished, as hereinafter described with reference to the accompanying drawings, in'which Fi 'ure 1 is a front-view of the machine.

Fig. l is afragmentary plan View, on an enlarged scale, certain parts being removed to disclose the construction of other parts. i Fig. 5 is a vertical sectional View, on an enlarged scale, of the washer forming mechanism. Fig. 6 is a perspective View, showing the construction of a washer conveying memher, and Fig. 'i is a view reprcsentinga inerchan dise envelop having a washer attached thereto; Q

Inr asmuch as this clutch terms-no part of the present invention, no description thereof is deemed necessary; it being sutlicieut to'say that'i'tmay be operated, at desired intervals.

The shaft 2 is belt driven by a' through a. t'readle or other device commonly employed in machines of this ,class, to cause the parts to go through a single cycle of operations, each time an envelop, l is presented 'in position to have was er s'ecured thcreto- The form of machine herein shown c011 templates the punching out of seamen-em a continuous strip of material, and" to "this end the frame 1 carries on one side a; bracket 4: in which a reel or'spool carrying a roll. of washer material inv strip form, such as heavy paper, journaled. The strip material l3 feeds downwardly from the reel, and is carried horizontally across the front of the machine, passing into the bight of feed rolls 7, 7 which are jou'rnaled in brackets 8, 8, the latter projecting outwardly from the frame 1 on theopposite side of the machine from the reel 5. To insure against an undue strain by the feeding of the ma terial, a guide wheel 9, which, is employed to change the direction of feed. is carried by one arm of a bell crank 10 whiclris pivoted at 11 to the frame. The other arm of the bell crank has attached thereto a spring 12 which operates to yieldingly press the wheel 9 against the strip; this serves in the usual way totalte up any slack in tl ejstrip and'al so permits, during feeding, ,ajmove-', ment of the wheel ,9 in response'to strain.

a; pawl. carried by an arm 21 loosely journald on the shaft cooperates with the ratchet 19 to impart rotative movement to the shaft when said arm 21 is rocked. The free end of arm 21 has an elongated slot 22 which receives a pin 23 carried on he end of a vertically reciprocating rod 24.

The rod 24 is reciprocated once for each rotation of the shaft 2 by means of a cam 25 on said shaft, co5perating with a fork mechanism of themachine.

circular apertured die 29 carried by the lower half of the holder. -The two parts of .the'die-holder afford a horizontal slit .or passageway 30 therebetween, through which the washer material is drawn by the intermittent action of the feed rolls 7, 7,

as above described. Preferably a plate 31 is attached to thatside of the die-holder on which'the strip of material enters the. slit 30, said plate providinga slot 32 somewhat narrower than the slit 30 and more closely conforming to the width of the washer strip or tape, in order to keep the latter in proper alinement. The opening through the die 29 corresponds in size to the washer which is.

to be punched out from the tape 6 at each I cycle of operations of the machine, said tape being somewhat wider than the diameter of this washer in order to preserve its continuity for the action of the feed rolls 7, 7 thereon, after the washers are punched.

- Coiiperating with the die 29 is a punch 33 which is attached to the lower end of a ,re'ciprocating sleeve 34 movable in a bearing 35 of the frame. Within the sleeve 34 and 4 bearing against an interior shoulder 36 per reduced thereof is a stiff spring 37, the other end of which bears against a flange38 which is capable of sliding inside the sleeve. A threaded cap 40 closes the end of this sleeve and an operating rod 41 passes loosely through this cap. The flange 38 is attached to rod 41 by means of a rod 42, whose upend, passing through the disk,

is threaded into the lower-end of rod 41.

As shown in Fig. 2, the rod 41 is-pivotally 7 connected at 43 with a lever 44 which is p1voted at 45 to the framework. At each cycle of operations of the machine the lever.44 isrocked or vibrated once in each direction,

by means of a rod 46 which carries a fork 47 for cooperation with a'cain 48 on the main shaft 2. a

As a consequence of this operation, the rod 41, starting downwardly from the position shown in Fig. 5, effects initially the descent of the sleeve-34 and punch 33, the spring 37 being of sufficient stiffness to ance, to move in unison. The punch 33, cooperatln g'w th the die 29, forms a circular disk whlch is carried downwardly through 'cause these parts, in the absenc; of resistthe die and against a stationary set 49 sup-- ported by the block'27. The movement of the punch 33 being thus arrested, the further descent of operating rod 41 presses the flange 38 downwardly within the sleeve.34,

to compress spring 37 and thereby to move the rod 42 independently'of sleeve 34. Rod 42 has projecting therefrom a punch 50 slidable in the punch 33 but normally, as shown in Fig. 5, terminating just short of the end of the latter. The independent descent of rod 42, as above described, after the disk of material has been punched out and pushed through the die 29, causes the punch 50 to operate, in conjunction with the central aperture 51 of the set 49, to punch a hole in the disk and thereby to complete the washer which is to be subsequently attached to the envelop.

In the space which receives the upper end of set 49 is adapted to slide a horizontal washer carrier 52. The latter is shown, in detail, in Fig. 6 and consists of an arm 53 in the form of a segment of a circle, the same being attached to a sleeve 54 which is adapted to vibrate about, the vertical axis provided by a pivot screw 55 carried by the framework. The under side of arm 53 has a groove 56 therein which receives the portion of set 49 projecting above the block 27, so'that said set forms no obstruction to the movement of said arm; When theoperation of punching out a washer from the tape 6 is in progress, as above described, the arm 53 is stationary, and in such position that the set 49 registers with an aperture 57 at one end of groove 56. This aperture57 provides a' shoulder 58; above which it is of the same diameter as the washer, the distance of this 7 washer material. Below the shoulder 58 the aperture 57 corresponds in size to the set 49, so that as the disk or washer is deposited by the descent of punch 33, it rests near its periphery upon the shoulder 58 and inwardly thereofupon theset 49. In this position it is punched out by the punch,50, as described above. I y I Aweb 59 projecting from sleeve 54 has an connected to a bar 61 extending toward the rarer-the machine, as shown Figs. 2 and upstanding lug 60 thereon which is pivotally formed by the punches -33 and 50, as above described, the action of cam 64 is inaugurated to swing the segmental arm 53 into the position shown in Fig. 4., the groove 56 riding over the set 49, from which the punch has been withdrawn by the return of the sleeve 3a to the position shown in Fig. 5.

' The washer, disposiil'within the aperture 57 and resting on the. narrow shoulder 58, is carried by arm 53 to a position to be operrated upon by the eyelet setting mechanism 4 of the machine, as hereinafter described.

ting mechanism,

by means of an eyelet. to the flap or body It is to be understood that this eyelet setwhich attaches the washer,

- portion of the envelop Fig. 7, may be of any allv attached well known type, such. for instance, as that described in Letters Patent No. 1,131,805, issued to me March 16, 1915, or in the pending parent application Serial No. 7 77 .998, of which the application for the above Letters Patent constitute a division. Or, if desired, the eyelet settingm-echanism may be of the form illustrated and described in Letters Patent No. 923,602, issued to meJune 1,

1909, and covering a machine which, simul taneous'ly with the-attachment of a washer to the flap of the envelop, Fig. 7 secures a ciosing cord 88 thereto by the same operation which sets theieyelet used to attach said washer For purposes of illustration, I have shown an eyelet chute 66 of the type described in the aforesaid Letters Patent No. 1,131,805, with its lower end in position to hold an eyelet beneath a spring pressed eyelet needle 67 adapted to remove the lowermost eyelet from the chute 66 as the set 68 descends, the needle being arranged to engage the eyelet frictionally and prevent its falling off after the lower end'of the chute has been pushed out of the way. The eyelet set 68 is carried by a vertically reciprocating plunger 69, moving in vertical ways 70 provided by the framework. The plunger 18 supported from a fixed pivot 71 by means of a toggle-joint composed of llnks 72' and 7 3, said joint being actuated by a rod 74 pivot- I at its forward end to the knee of the toggle joint and at its rear end to one arm 75 of a bell crank which is pivoted at- 78 to the frame. bell crank is pivotally connected at its end to an actuating rod 7 8, which is driven from an oifset portion of crank 79 of, the-shaft 2. As is usual in mechanism of this nature, the actuating rod 78 includes a yieldable portion 80 to prevent injury to the machine in the event that the complete descent of the set 68.

prevented by a broken or deformed eye- Another arm- 77 of the let, or by any other unforeseen circumstances.

With the flap 84: or body portion 85 of the envelop, Fig. 7, in proper disposition with respect to the usual lower needle 81 of the eyelet setting mechanism, (see Fig. at) the descent of the set 68, carries the eyelet 86 into the central aperture of thewasher. 87, as held in position by the swinging arm 53. The washer 87 is flexed or pushed through the aperture 57 of the arm by this; movement, being strung in efiect upon the neck portion of the eyelet 86. The washer being thus removed from the arm the latter is free to return to a, position where it may receive another washer when the cycle of operations is repeated. and its return is permitted because the aperture 57 is opened, as at 82, for movement past the set 68. The continuing descent offset 68 eifects, in conjunction with the anvil 81, the flanging of the eyelet to securely affix the washer to the envelop, as well known in the art to which this particular portion of the mecha nism pertains.

It is to be understood that the present invention contemplates the employment. in conjunction therewith, if desired. of mecha-- nism for applying a reinforcing tab on the other side of the envelop wall from the washer, as set forthin the aforesaid Letters Patent No. 1,131,805; to this end an oper-- ating connection 83 may be included for actuating the feeding devices for the tape "from which the tabs are made, but since this feeding mechanism forms no part of the present invention, it is deemed unnecessary to disclose the same. In. such a case the lower needle 81 would be made shorter than herein shown, and would constitute in min nection with the set a means for punching through the body of the envelop,

It is also to be understood that the present invention contemplates the attachment of a washer simultaneously with the aflixing of a closing cord thereto,-as set forth and described in the aforesaid Letters Patent. Yo.

923,602. In such a case the connection 83 would serve for the operation of the string feeding means, not herein shown, since the same constitute no part of the present invention. Under such circumstances the lower needle 81 would be constructed substantially as shown, being made hollow and open on one side for the passage of the string, and as described in said Letters Patent No. 923,602, would cooperate with the set 68 in severing the string as wcll as in setting the eyelet usedto attach the string and washer to the flap of the envelop.
