Be "it known that I, Mn'rrrrrnw Vmnnnonn, a citizen of the United States, and a 1:631 dent/of Brooklyn, in the county of Kings and Potato of New York, have invented certain new and useful Improvements in Man chines for Applying Patches and Fasteners to Envelope, of which the following 18 a specitieatiom.

My invention relates to that class of machines in which the nlasps and patches for receiving said clasps are applied to the -enveiops by the same operation, the pr mary object of this invention being toprovlde an improved construction, combination and arrangement of parts, which will operate in an improved manner to swure the spurs of the fastener to the envelop and which will be adapted to :permit the necessary hdJ tlStmerits between the-fastener feeding and the SPMIHSGGUD-lfig devices to meet the require ments of various sizes of envelops, whale at the same time maintaining the proper relationship between the mechanisms for at teaching the clasps and washer patches. =0ther and further objects will appear in the specification and be specifically pointed out in the annexed claims, reference being had to the accompanying drawings exemplifying the invention .in its application to a well known type of clasp envelop.

in the drawings Figure 1 is a front elevation of a machine constructed in accordance with the principles of the present invention. Fig. 2 is a side elevation of the same, parts being broken away to more clearly show other parts 'of' the machine. Fig. 3 is altop plan view of the same. Fig. 4 is .a fragmentary detail elevation of parts shown in Fig. 2 on an enlarged scale. 5 is an end elevation of the parts shown in Fig. at, corresponding with the point of view of Fig. 1. Fig. '6 is an enlarged detail elevation of parts shown in Fig. 4. Fig. 7 is an end elevation of-thesarne. Fig. 8 is a fragmentary top plan view corresponding to Fig. 3. Fig. 9 is a fragmentary front. elevation of details shown in Fig. 8. Fig. 16 is a detail plan view of. the anvil plate for deflecting the spurs of-the clasp and a transverse sectionlof the same, and Fig. 11 is a plan view of a clasp envelop with the flap-open. l

Referringmore particularly -to the. drawin-gs s udio the embodiments shown therein, the legs 1 support-a main bed plate :2. Prom jecting upwardly from the base plate 2 are spaced bearing lugs 3 in which is journaled :a main drive shaft or cam shaft a, said shaft being provided on one'end with a drivung pulley 5 provided with a clutch element (6 which is movable into and out of engageunent with a clutch element '7, which is re .ciproca-ble along the shaft 4 under the acltion of "a spring 8 outo f the right hand [bearing log 3. The pulley 5 turns tfreely on the shaft 4 while the clutch eleunent 7 is connected to the shaft by means of a spline (not shown on the drawings). A earn plate 8 is integrally formed with the clutch element 7 being cooperatively related to a stop pin 9, which is normally aretained in upper position by a spring 10 which thus serves to hold the clutch elements 6 and 7 apart. A treadle lever 11 pivoted at 12 to the leg 1 has its outer end connected by a connecting-rod 18 with the stop pin 9 to permit the clutch elementsfi and 7 to be thrown into engagement. A tie bar 14 which extends between two of the legs 1 (see Fig. 1) is provided with a standard 15 having a vertical slot 16 within which is vertically adjustable a bolt 17 which serves to secure the depending flange 18 of an envelop supporting bracket 19 to the standard 15. The bracket 19 is provided with aside rail 20 for affording lateral support to the envelop 21 as it is moved into and out of position in the machine as sho n in Fig. 2.

As shown most clearly in Figs. 2 and 3 a horn 22 is rigidly mounted upon the base plate 2 by having its relatively heavy pad block 23 secured to one of a plurality of spaced bars 24:. As shown best in Figs. 6, 7, 8, 9 and 10, this horn 22 comprises a plate 25 whichis pointed at its outer end and is provided with a dove-tailed groove 25 for reciprocably mounting a slide 26 carrying an anvil plate 26. The slide 26 is provided with a pin 27 which projects into a slot 28 in the end of a crank arm 29 which is rigidly connected to an oscillatable rod 30. Projecting from the inner face of the anvil 26' is a pin 27 a which moves in a longitudinal slot 26 in the slide 26 when the anvil is adjusted on said slide in the manner to be hereinafter pointedout. As shown in Fig.

2 the rod 30 derives its power through a crank arm 31 which is keyed to the rod. 30

and has its onterend pivotally connected with an operating lever 32 the rear end of which is provided with a yoke 33'which slidably engages the shaft 4. Lever 32 carries a cam roller 34 which runs on a cam 35. In order to provide simple and eflicient means for shifting the clasp fasteners successively into position to be secured to the envelops which are disposed one after another over the horn as shown in Fig. 2, the fasteners are manufactured in such a way as to form a continuous sheet metal ribbon which is conveniently handled by having it coiled into a roll 36, said roll being preferably journaled on a pin 37 which projects laterally from the upright 38 of an angular pedestal or support, the horizontal arm 39 of said support being provided with a slot 40 which permits it to be adjusted laterally with respect to the plane in which the clenching operation to be presently described, takes place. A stud 41 extends through said slot 40 being threaded into the superstructure 42 of a frame 43 which is secured to the main bed plate 2 by means ofbolts 44. Integrally formed with the superstructure 42 of the frame 43, are a pair of spaced overhanging bracket arms 45 which carry a bar 46 which is adjustable laterally with respect tothe ribbon or band 36. Interposed between the bracket arms 45 is a collar 47 which carries a set screw 48 which is adapted to lock the bar 46 in any position to which it may be adjusted. In th1s "manner the clasp tape is made adjustable toward and away from the plane of the patch washer tape to be hereinafter referred to, thus adapting the machine to be used with envelops of various sizes. Depending from the squared extremity 49 of the bar 46 is a guide or chute 50 through which the clasp tape is fed by means of claw 51 which is pivoted at 52 to the outer end of a lever arm 53 which is oscillated by a shaft 54 from one end of which projects a radial arm 55 which is connected by a spring 56 with a fixed pin 57. Said'shaft 54 is journaled in the upper ends of a pair of spaced standards 58 which are rigid with the bed plate 2. A cam arm 59 which is keyed to the shaft 54'is provided on its outer end with a cam roller 60 which runs on the periphery of a cam 61 and thus serves to impart the up and down movement to the claw 51 which is held resiliently 'to its work by a spring 62 carried by the crank arm 53. A spring dog 63 is secured to the square end 49 of the bar 46 for preventing retrograde movement of the clasp tape 36.

Referring again to Figs. 6 to 10 inclusive,

the chute 5O embodies a central guide rail 64 over which the connected clasps are fed until the nibs or spurs 65 reach a pair oflateral recesses or openings 66 in theguide when a pair of bending blades or plates 67 carried by a reciprocating shaft 68 engage said spurs to deflect them inwardly toward the horn or shear 69 of the rail 64. The plates or blades 67 are rigidly secured to a stamping head 69which is in turn rigidly I cesses 70 in the anvil plate 26'. When the I stamping head 69 is again moved toward the anvil plate 26, the spurs 65 are forced through the wall of the envelop which is disposed over the bifurcated leaf spring 71,

which is embedded at one end in the plate v 26. As the stamping head again recedes, the spring 71 forces the envelop with its clasp outwardly while at approximately the same time, the plate 26 is moved endwise by the oscillating rod 30 which brings the solid neath the central portion of the fastener so that the next inward movement of the stamping head 69 clenches the spurs 65 in position. As each of the fasteners is forced outwardly by the spring 71, the soft flexible nature of the spurs 65, permit the fastener to be readily disengaged from the beveled tongue between the recesses 70, the extremities of said spurs being still deflected to some extent toward each other. When therefore the fastener is driven against the table portion of the anvil, said spurs are clenched into place. During the first infiat portion at the left end of plate 25 beward movement of the stamping head 69',-c/'

the sharp corner 72 coiiperates with the' sharp corner 73 on the end of the shear 69 to shear the lowermost clasp from the ribbon. In order to impart the reciprocatory movement to the rod 68 and stamping head 69, said rod' 68 has its outer end in operative engagement with a crank arm 74 which is keyed to a rock shaft 75 which is journaled in brackets 76 rigid with the bed plate 2. A-rock arm 77 keyed to the shaft 75 is provided with a cam roller 78 which runs on a lateral face cam 79. Secured to the extensions 80 of the bed plate 2 are ,a'pair of oppositely disposed punch blocks 81 having their adjacent ends provided with hearing bosses 82 through which the hollow disk punching rods 83 are reciprocated by the operating levers 84 which are pivoted on the pins 85, removably socketed in the bed plate 2-. A punch rod 86 extends through one of the punch rods 83, being reciprocated by the operating lever 87 pivoted on the removable pin 88. The operating levers 84 and 87 are provided with open forks at their swinging ends which embrace the respective rods 83 and 86. Each of said operating lovers are moreover provided with cam arms 89 (shown in dotted lines in Fig. 3) which more-me slide in the slots 90 between the cam blocks 91 carried by the power shaft 4. This construction permits the instant removal of the cam levers whenever desired. In order to properly set the operating levers with respect to the punch rods, each of said rods is threaded exteriorly and provided with a pair of adjustable abutment nuts 92 for each lever. Rolls 93 of disk-forming tape are journaled on pins 94: said tapes being made to pass upwardly around guide pulleys 95 and thence .to gumming rolls 96. Said tapes can be drawn close about the rolls 96 by means of tightening forks 97 pivoted at 98. After leaving the guide rollers 99, the tapes are drawn upwardly through the bosses 82, each of said bosses being provided with a throughW-ay 100 as shown in Fig. 8,*

being thus guided on opposite sides of the extended flap of the envelop. quence as the oppositely disposed punch bars 83 move toward each other, each cuts from one or the other of tapes 93, an annular reinforcement disk which has been previously gummed. As these disks are glued to opposite faces of the flap, the punching rod 86 perforates the flap. 1

in order td provide simple and eflicient means for adjusting the reciprocating movements of theanvil with respect to the path traveled by the band of fasteners, the outer end of the slide 26 is provided with a longitudinal series of holes 101. Into any one of these holes a screw 102 is adapted to be threaded, said screw being mounted in a countersunk aperture in the outer end of the anvil plate 26.

The operation of my improved machine has been brought out in the foregoingdescription. Briefly stated the advantageous results accruing from a machine embodying the present invention are as follower The improved method whereby the clasp and re inforcement disks are applied simultane ously and at accurately predetermined distances apart is made possible by the employment of a single rigid member such as the horn 25, provided with means for locating both the clasp and reinforcing disk. Zlo adapt the machine fordiiferentsizes of envelops, the clasp applying device is adjustable toward and away from the disk applying apparatus. Collateral with these, the

employment of a shifting anvil plate with an adjustable connection between it and the device for reciprocating it. These and other advantages will. be understood from the claims appended hereto.
