The eccentric 44 is so located with respect to the eccentric 46 that it will advance the slide 33 slightly ahead of the perforating plunger 41, that is, the slide reaches its advance movement toward the die" plate 38 slightly before the perforating plunger 41 reaches its advance movement toward said plate..

A plunger supporting slide 47 is mounted in a slide-way 48 formed in the bed on the opposite side of the center thereof, from the slide-way 34, .this slide being held in place in a manner similar to that above described, with respect to the slide 33, one of the dove-tailed shaped projections being shown in Fig. 6. This slide bears a washer forming plunger 49 having a central opening 50 in which, in some instances, a perforating plunger, similar to the plunger 41 and operated in like manner, may be located. In the form of machine herein shown, however, the perforating plunger is omitted and the plunger 49 is formed with an opening 51, constituting a die coiiperating with the plunger 41 to produce .the central openings A rivet securing plunger 52 is secured to the slide 47 on its opposite side from the washer. forming plunger 49, the plunger 52 having a centrally located recess in which a rivet punch 53 is removably secured, projecting beyond the end of the plunger 52. This rivet punch is tubular and contains a rivet supporting pin 54 having a head 55 to retain it in place, a spring 56 being located in the recess behind said pin and thrusting against it to force it normally outward.

A cap 57 secured to the plungerlsupporting slide 47, has ,a slide actuating rod 58 pivotally secured thereto, said rod being connected with an eccentric 59 secured to the cross shaft 29, by means of which eccentric the slide 47 is reciprocated. The cap has an opening therethrough registering with the opening 50 in the plunger 49, as clearly shown in Fig; 4 of the drawings. An adusting screw 151 is mounted in the cap 57 and serves as a back stop to properly locate the rivet securing plunger 52 by determiiiing its backward-position in the slide, and a like or similar adjusting means may be emare placed on edge, and a supporting shoe 62 is secured at one end to a block 76 locatedin the slide way 48 and secured to the bed, the end of theshoe being pointed and extending along the groove 39, as clearly shown in Fig. 4, in position to project into an envelop, the end of the flap of which rests against an envelop stop 63 .to be hereinafter described. This shoe 62 has an opening 64 to receive the washer formingplunger 49 by means of which opening and plungernvashers to be affixed to the envelops are produced. A die 98 against which the" rivets are headed by the punch 53 is secured to the shoe, and an envelop guide 99, in the form of a spring, is secured at one end to the shoe and projects to guide the envelop over the die 98 when the former is placed on the shoe, the guide yielding and its free end moving toward the shoe when the riveting takes place. f

A supporting bar 65 is secured to the legs 10 at the front of the machine, and. extends across the machine from side to side, a .rest support 66 projecting upwardly from said bar' at about its center, and having the envelop stop 63, that is adjustably supported on the bed 11, ocated over or resting against its upper end. A dovetail shaped rest guide 67 is secured to the rest support, the end of the rest 61 having "a dovetail shaped groove to engage said guide, as shown in Fig. 4 of the drawings, this groove extending into a base 68 of the rest, which base is provided with a set screw (see Fig. 2) by means of which the rest may be ad justably secured in any desired position.

Tape supporting spools 71 are rot.;'i;ably supported in proper tening rolls from, the guide rolls 73, also holding the tapes down upon said moistenin rolls. The tapes pass from the guide r0 ls upward through tape openings 75 "formed through the restv 61, and in the side of the block 76, back of the shoe 62, for the side of the machine,

said openway 34c, and being located back of the die plate 38, for the tape on the right-hand side of the machine. The shafts of the moisintermeshing gears 78 sehas'a ratchet 79 eeured thereto and engaged -"by a pawl 80 pivotally mounted on a pawl actuating lever 81 rotatably sup orted' on said shaft and connected by a r0 82 with v a lever 83 pivotally supported on the bed,

. a curved bar 84: extending around the shaft 28 and pivotally secured to the lever 83,

. conneeting said lever c) wlth an actuating rod .85. having its lower end forked to straddle I the shaft 28 and bearing a roll 86 riding in contact with a cam 87 secured to the shaft 28' and by means of which said rod is reciprocated, thereby imparting a step by step moistening rolls through connection justdescribed.

Apost 88 rises from the bed 11, this post being curved to locate a holder disk 89, r0-

tatably supported at its upper end, over a rivet feed for supplying rivets to the mech anism. A holder 90 is secured to the disk in'the form of a Wire upon which rivets 91 are placed. These. rivets are ofa form commonly used on encentral tubular portion arms 93 as shown in Fig. 5, arms are adapted to be passed 92 with flexible v.velop and then ,bent backward upon themthe envelop in ul arportion of the rivets located in the bracket 97. The

The lower part disk 89- may berotated, as by means of a handle 95, to place the holder in a. position diametrically opposite to that shown in Fig. 2, in which. position the holder may be loaded. After it has been loaded, and before it is placed in position to feed, an

aliner 96, pivotally mounted on the post 88 is employed to aline the r" et arms so that they will pass into the gui 94 when the holder is rotated to the feed position shown in Fig. 2. This aliner consists of an arm having a groove to receive and fit upon the central hub portion of the rivets, this arm being pivotally mounted on the post, as clearly shown in Fig. 8, it being of a length to engage all of the rivets on the holder when swung upwardly from the position shown in Fig. 1, above described.

The bracket 97.1s

thus alining the rivets as secured to the block 76, rising therefrom to support a rivet carrier rotatably supported thereby. in branches 100, This rivet carrienconsists of a disk 101 having a 103 is secured, the disk 101 being also pro vided with journals 104C resting in bearings in the branches 100. A series of recesses 105 hub 102 on which an annular disk are formed radially within the carrier, onehalf of each recess being formed in the disk 101 and the other half in the annular disk 103', the latter having lugs 107 from rivet holding fingers 108 are seated upon a spring 109 located in a' recess .in the hub, as clearly shown in Fig, 6 of the drawings. A track 110 is secured at its lower end in a groove in the block 76, this track curving over the bracket 97, as clearly shown in Fig, 5 and having a cam plate 111 secured at its upper end, and located in position to be engaged by the lugslO'Zto move the rivet holding fingers radially inward in the cal rier and permit them to pass under the end of the track 110, said lugs, however,-being released from said cam and allowing the fingers to spring outward and enter the opening in the bottom rivet supported on the holder 90,. as shown in Fig. 5, from which position, in the rotation of thecarrier, the rivets are carried downwardly through -a runway 112 consisting ofa groove formed in the 'track 110. This groove is closed by a an extension from the guide 971, this cover holding the rivets within the groove or run'-' way'as they travel downward therein. The movement of the fingers withdraws them from the openings in the rivets at a certain point, from which the rivets fall on to a rivet rest 114 located at the lower end of the runway, the rivet being thus held in position for action of the rivetslots 106 within'which located. The rivet holding fingers are each if desired, constitute in a curved path mg punch 53 operating through an opening 115 in the track 110 and against the die 98.

of the runway 112 is closed by a gate 116 mounted on a latch 117 pivotally supported on the block 7 6 and having a cam 118 located in the path of movement of the end of the plunger 52. This gate has an opening 119 in its edge to receive the hollow hub of the rivet, and the cam 118 is so formed that, as the riveting plunger 52 moves forward, it operates to move the gate backward at the proper time to allow the rivet to be carried by the pin 54 against the die 98, a spring 160 returning the latch 117 to its normal position, as shown in Fig. 4. A ratchet wheel 120 is secured to one of the journals of the carrier and is actuated by a pawl 121 supported on a pawl lever 122 mounted onthe journal and connected by a rod 123 with an actuating arm 124 mounted on the slide 47. A pin from the arm 124 is located in a. slot 125 in the rod, and a spring 126 connects the arm 124 with the lever 122 independently of said rod so that, should any obstruction present itself to movement of the carrier to feedirivets along the runway, the spring will permit the arm 124 to move and thus avoid injury of parts, the engagement of the pin with the slot posi- .tively moving the pawl to reengage the ratchet.

A tape feed support 127 rises from the bed 11 and has a foot 128 by means of which it is secured to the bed, this support having branches 129-13l) at its upper end in which a tape feed shaft-131 is journaled. A tape feed operatingv lever 132 is rotatably mounted on the shaft and has a pawl engaging a ratchet 133 secured to the shaft.

The lever 132 may be formed intoa handle 134, and it is connected with the actuating rod 85 whereby the tape feed is actuated by means of the cam 87 on the shaft 28, from whichit will be seen that the feed of the tape at the moistening device and at the upper part of the machine is simultaneous and from the same source. A feed wheel 135 is secured to the shaft 131, this wheel having teeth to engage with teeth on a feed wheel 136 loosely mounted on its shaft and also journaled in the branches 129-130, the

i teeth on one wheel pressing the paper tape with the other.

into the space between the teeth on the other wheel; The shaft of the feed wheel 136 has cams '13? arranged to engage flanges 138 .projecting from the branches of the support 127. This shaft is mounted in boxes 139 located in slots in the branches and pressed towardthe feed wheel 135 by springs 140 seated upon the boxes and thrusting against a cap 141 secured to said branches. Ahandle 142 is secured to one of the cams or to Y the shaft, and by means of this handle, when the cams are caused to engage the flanges at their highest portions, the teeth of the feed wheels will be forced from engagement each Grooves 143 are formed in the feed wheels in which guides 144 extend,

regular feedconsists of a main feed wheel 145 mounted on a bracket 146 extending from the support 127, said main feed wheel having studs 147 arranged to engage the openings in the paper tape made by cutting the washers therefrom, each succeeding stud engaging the succeeding openings in the paper tape and thus imparting a regular step by step feed movement thereto. This main feed wheel is rotated as by means of an intermediate gear 148 mounted on a stud on said bracket, said gear meshing with a pinion 149 formed, in the construction herein shown, as a part of the feed wheel 135, said intermediate gear also meshing with a gear 150 mounted to drive the main feed wheel 145.

The operation of the device is as follows: It will be understood that in the first few operations of the machine the tapes 72 are engaged by the feed wheels 135-136 that draw upon the tape until a sufficient length is obtained to engage the studs 147 of the main feed wheel 145. after which the handle 142 is operated to dis ngage the feed wheel 136 from the feed wheel 135, by engagement of the cams 137 with theflanges 138.

The parts being in the positions shown in the figures of the drawings an envelop is placed upon the shoe 62 resting with its edge upon the rest 61 and with the end of the flap against the stop 63. Pressure upon the treadle 24, through the connecting mechanism, disengagcs the starting and stopping pin 21 from the cam 19 and the spring 18,

place during a single rotation of the shaft 12, the stop 20 striking the pin 21.

The rotation of the shafts 28 and 29, through the intermeshing gears and connections, simultaneously moves the perforating and supportin slide 33 and the plunger sup porting slide 4 toward each other, in which operation the supporting plunger 3 5 1s moped through the opening 40 and against This rotates the driving. 1

, point and held the rivet in place. The latter being now free to be moved forward is carried by the pin 5% against the die 98, the pin striking the die and retreating into the riveting punch'53 in the rivet securing plunger 52. The latter now engages the rivet, forces it through the back or" the envelop and heads it on the die 98, securing the rivet in place. On the return movement the spring 56 will forcethe rivet supporting pin 54= into the position shown in the drawings and the spring. (not shown) will return the latch 11? to the position shown, placing the gate in position to cover the runway to retain the next rivet which shall pass down the;runway in positioiron the stop 11%. In this movement of the plunger supporting slide 47 the washer forming plunger 49 is carried forward, engaging the tape 72 in the tape opening 75 on the left-hand side of the shoe 6:2, cutting a round disk -from said tape by the action of the die opening 64, which disk is carried through the opening 64 against the flap of the envelop within the V groove 39, the plunger 49 coming to rest with said disk lying against said flap.

The movement of the perforating and sup porting slide 33 above described, moves the washer forming plunger 36 simultaneously with the plunger 49, the end of the plunger 36 engaging the tape in the opening (5 back of the die plate 38 and in connection with the die opening. 37, forming another disk from said tape, carrying said disk through the opening 37 and against theopposite side of the flap of the envelop from that against which the disk first above described is brought to rest. In this operation the perforating plunger all is also carried forward by means of the eccentric 46,:the plunger 11 reaching its forward position just after the slide 33 has reached its forward position. The slight dwell in the movement of the slides 33 and i7 caused by the eccentrics 14 and 5 passing their centers is made use of for the operation of the plunger 4-1 which, during such dwell, passes through the two disks and the envelo flap and in connection with the die opening 51 in theplungel-e9. produces a hole, thus completing the formation of the washers, the piece taken out from the disks and the envelop flap passing into'the opening 50 in the 'die 19, and eventually, by the successive location of the pieces within said opening, out through the opening in the cap 57 The pressure of the diesat the end of the plungers 36 and 49 will cause the washers, which have been produced from the tapes having one side containing an adhesive moistened, to be firmly afiixed to the opposite side of the envelop.

At the time of starting the operation of the machine, as above described, the end of a finger 108. will be located in the bottom rivet on the holder 90. The pawl 121 will, through the operation of the actuating arm 12% on the slide 4:7 and the connecting parts, rotate the rivet carrier a one step movement,removing the bottom rivet, and passing it along the runway, and in a further movement of the carrier the rivet will be located in' position so that the pin will pass out of the opening in the rivet and allow it to drop on to the stop 114. As one rivet is being removed from the holder 90, the lug 107 on the next succeeding plunger engages the cam plate 111, drawing the finger radially inward so that-it may pass under the end of the track 110, and just as soon as the lug disengages from said cam plate the finger snaps outwardly into the b-pening in the rivet. 1

The rotation of the cam 87 by the shaft 28 through-the actuating rod 85 and lever 83 and connecting parts, will simultaneously operate the ratchet feed to impart a step by step movement to' the moistening rolls 70 and to the main feed Wheel 1145, thus imparting a step by'step movement to the paper tapes which, being passed through the water or like moistening material within the boxes 69, are properly moistened to be aliixed to the envelop flap hereinabove described.

ln placing the rivet-s upon the holder 90, the handle 95 is operated to rotate the holder disk 89, thus placing the holder 90 in a di.a metrically opposite positionfrom that shown in the figures, in which position, by means of a loader or otherwise, the rivets are placed upon the holder. The aliner 96- is now swung upwardly projecting the hubs-92 of the rivets into the groove in the aliner, thus bringing all of the arms 93 into alinement, after which, the aliner being moved to its normal position, as shown in Fig. 1, the holder is returned to'its normalposition, as shown in Fig. 2,. and the arms of the rivets being thus alined will properly enter the groove in the guide 94.,

It will be understood that if it is desired to affix a Washer to one side of the envelop flap only, this operation may take place simply by omitting a paper tape in one of the openings 75 on that side of the flap to '125 which it is desired'th'e washer shall npt be ailiXQd. r it I I i l I While I haveshoivn'and described herein a form of mechanism employed by mefor effecting the desireda'esults, it will be understruction herein shown and described.

The holder disk 89 is yieldingly held in different positions, and especially in its feeding position by means of a spring seated pin 152 and having aibeveled end engaging recess 153 to resiliently hold the disk. By application of some force to the handle 95 the disk may be disengaged and moved to a different position.
