To all whom 'it 'may concern:

Be it known that I, HENRY Tan-Norman.

Jr., a citizen of the United States of s' 1t is an object of the invention to pro-y vide improved fastener applying mechanism.

The present applicationis a Vdivision of an earlier application filed by me on December 3l, 1917, Serial No. 209,729, which application was a continuation in jpart of a still earlier application filed by me December BO, 1915, Serial No. 69,392, now Patent- No. messen dated Mann i2, uns.

The invention has been developed and for convenience will be described as embodied in a machine for applying so-called double button and string fasteners to envelopes.

For convenience in the description of the particular embodiment of this invention, it may be. noted that such envelopes are generally provided with a comparatively stiff fastening washer upon the outside of the body of the envelope'united thereto preferably bymeans' of an eyelet which is upsetto engage the washer and hold it securely in position in relation to the body ofthe envelope. A similar fastening` washer is similarly aliixed to the flap of the envelope and preferably ai comparatively light rein-v forcing washer is used upon the inside of the flap; the two being fastened by'an eyelet passed through the washers and through tl. e envelope flap. The string, which is used to effect the closure of the envelope,`prefer ablyY has one end fastenedl under the eyelet which attaches the cooperating` washer Renewed February 9, 1923.

In the following description of the illustrative embodiment of the invention, the

n general structural features of the machine will first be described and then, in the se` quence indicated, the illustrative mechanism for aiiixing the fastener and washer to the body of the envelope; the illustrative mechanism for forming and atixing the fastener and reinforcing washer tothe flap of the envelope; and lastly the illustrative mechanism for feeding, fastening and cutting the string.

Referring to the drawings it will be seen that the` greater part of the mechanism is mounted upon a bed-plate or table 1 supported upon standards i?. A main shaft' i3, journal'led in suitable bearings upon the table 1, is provided with a balance wheel fl and is adapted to be connected with a driving pulley 5 by a suitable clutch mechanism located at the right hand side of the machine. The driving wheel 5 carries a jaw 6 and is. during the operation of the machine, rotated continuously from a suitable source of power.

The operation of the machine to aflix the double button and string fastener.7 is preferably accomplished in one revolution of the main shaft 3 and the clutch mechanism is therefore designed to rotate the main shaft through one revolution and then automatically disengage. A clutch collar 7 is keyed to the main shaft (see Figures and 11) and is slidable thereon. This collar has jaws 8 to co-operate with jaws 6 on the hub of the driving pulley which rotates freely on the main shaft, and a spring pressed plunger 9 tends normally to force the jaws into engagement. A flange 10 upon the collar '7 has a cam surface 11 and, as shown in Figure 11, this cam surface bears against a stud 12 which holds the collar 7 away from jaws 6. The stud 12 is held normally in the position shown in Figures 2 and 10, by a spring 13 which is attached to the bed of the machine and to a lever 14 passing through the lower end of the stud. A treadle 15 is connected by suitable links 16 and 17 with the lever 14 so that upon depression of the pedal and its immediate release, the collar 7 will be forced to the right in Figure 10 to engage jaws 6 and 8 and rotate the main shaft 3 through one revolution, the stud 12 co-operating with the cam 11 to withdraw the collar 7 toward the end of the single revolution.

As shown in Figure 3 a notched collar 18 is fast to the main shaft 3 and a spring pressed lever 19 engages the notch in the collar 18 to prevent the back lash of the main shaft.

Coming now to the mechanism for affixing the fastening washer to the body of the envelope and referring particularly to Figures 3 and 4, means are provided for feed-V ing through a strip of tape, forming a washer from the tape, feeding an eyelet into the proper position and actuating the washer forming mechanisml to affix the washer to the body of the envelope. In Figure 3 it will be seen that shoe 2O projects from a stationary part of the machine and carries an anvil 21. A light spring guard 22 is fastened to the outer end of the shoe and overlies the anvil 21. This spring serves to press the body of the envelope away from the anvil when the fastening eyelet has been upset and contributes to the speed of operation of the machine by permitting a direct withdrawal of the envelope. T he shoe, anvil and releasing spring are shown in section in Figure 4. A light spring 256 (see Fig. 3) serves to press the envelope flap toward the side of the shoe so that it may be quickly withdrawn from the machine atthe completion of operation. v

Slidably mounted in the machine, as shown in Figure 3, is a reciprocating plunger 23. Suitable means are provided for actuating this plunger from the main shaft, the same being herein shown as cti-operating beveled gears and the latter being mounted upon a shaft 26 suitably journalled in the frame, and carrying at its end opposite the gear 25, a crank arm 27 to which a connecting rod 28 is attached. rl`he connecting rod is attached at its other end to a cross bar 29 which is fastened to the plunger 23 by means of a block 30 and collars 31. Through this connection the plunger 23 will be moved forward and back upon a single revolution of the main shaft. Referring to Figure 4 a second plunger 32 is mounted below the plunger 23 and carries at its end a punch Suitable means are provided to actuate the plunger 32 simultaneously with the plunger' 23, a block 34 connecting the two at their outer ends. The plunger carries a hollow punch 35 with a sliding pin 36 pressed forward by a spring 37 which is mounted within the punch 35. A die plate 38 is rigidly attached to the machine and is provided with a hole 39 to cooperate with the punch 35 and a hole 4() to co-opera'te with the punch A vertical channel 41 is formed by a guard plate 42 interposed between the die plate and the punches. rThrough this channel is drawn a strip of tape 43 from a. supply roll 44, shown in Figures 1 and 2 as mounted upon a spindle 45 projecting from one of the standards of the machine.

Suitable means are provided to draw the tape step by step through the channel 41, the increments of movement corresponding to the distance between the axes of the punches 33 and for a purpose which will hereafter appear. T ape feeding means are herein shown as a pair ofco-operating feed rolls 46 and 47, shown diagrammatically in Figure 4, and also in Figures 2 and 3. Suitable means are provided to actuate the feed rolls, the saine being herein shown as a cam operated ratchet and pawl mechanism. The upper feed roll is mounted upon a shaft 48 suitably journalled in bearings which permit it to be pressed toward he co-operating feed roll 47 by set screws 49, This shaft also carries another feed roll which will be later referred to. A ratcuet 50 (see Figure 3) is fast to the shaft 48 and a spring pressed pawl 51 is carried upon a pivoted arm 52 which is actuated through a link 53 by an arm 54 upon a vertically slidable standard 55 suitably journalled in the bedplate of the machine and held in lowered position by a spring The arm 54 carries a roller which rides upon a cam 58 fast to loo 1 (l il an eyelet so that it may be picked up by the f pm 36, Figure 4, in the plunger 35 and carried forward, passed through a holelin the washer and thereafter upset against the an-l vil 2l to fasten the washer to the envelope body. Such means are herein shown as follows: Referring to Figure l a suitable eyelet selector box is mounted upon a shaft 6l journalled in suitable bearings above the machine. rihe eyeletbox,y shown in more detail iii Figure l2, may be `of any suitable construction adapted to delivereyelets to a channeled gutter leading to the eyelet up-. setting mechanism. The boX is rotatedfrom the niain shaft through belts 62 and 63 runiiiugover pulleys 64,65, 66 and 67.

The eyelet box deli-vers eyelets to the gutter and the eyelets will slide downthe gutter until they reach-an escapemeiit mechanism, shown in Figures 7` 8 and This cscapenunt mechanismiis adapted to releasethe eyelets one at time `and permitthe released eyelet to fall tothe bottoniof the gutter where it is in position for engage-y Referr ring particularly to Figures 7, 8 and 9 it nient by thek upsetting mechanism.-

will be seen `that the `escapement mechanism comprises a reciprocatorymember 71 having two knifeedges 72 andf73 staggered in relation tothe gutter. As shown'in Figure 7 the eyelets are intended to pile upand be` caught upon the upper knife edge 72. Upon a reciprocation of themember 7l to the right, the knife edge72 will release-an eyelet fronrthe coluiniiof eyelets and perinit it to drop, against the knife edgew73w llpon the reversefreciprocationto the left,

knife edge will pass betufeen-the eyelet-rest vthe feed roll'actuating arm 54. Thus when the feed roll is actuated to move the strip ing down the gutter froInthe escapement mechanism is stopped andheld in alignment with the pin 36.

As soon as the gates 77 have closed behindL the punch35, the eyelet escapeinent mechanism maybe actuated to drop another ,eyeletv into position; thus-completing. a.

single cycle of operationof this `part of theVA apparatus. t

Proceeding withV thedescription of the-- mechanism,` .the means for forming andafti.\l ing areinforcing washer to the flap of the.

.envelope is bestshown in Figure 5 and its 1 relative location to the mechanism pist deforivard, the eyelet escapement.mechanism` scribed is best shown in Figure Refer-l ring to Figure 5, a Lreciprocating plunge-1&8() is `suitably inountedin the bed Aof the machine and is adapted vto be `actuated in unison with the plunger 23, It is connected to the44 cross ban 29-by ablock 81 as shownin Figure 3. .l ust belowv the plunger SO is a plunge er 82 also fastened in the. .block 8l. The endl of the plunger forms a punchwhich co1.

operates with a hole 83 in a die plate 84 and the plunger carries an upsetting anvil 8,5.. Theplunger ,82 carriesapunch 86 to. co-` operate with a hole 87 in thedie plate .84. A channel-88, Figure 5, vis formed betvveenithe supported by the pin 36, which asthe punch s die plate 84 and the two punches and through this channel is passed a strip of reinforcing washer material 89. This strip is drawn from a supply roll 89', Figure 1, mounted upon a spindle 89 projecting from one of the standards 2 and is led up over a guide roll 90 and between feed rolls 91 and 92; the feed roll 91 being mounted upon the same shaft 48 which carries the feed roll 46 and the feed roll 92 being mounted upon a shaft 93 upon which the feed roll 47 is also mounted. The feed roll 91 is rotated with feed roll 46 and the tape 89 is moved forward step by step as is the tape 43. Thus at each reciprocation of the block 81 the punch 86 will form a small hole in the tape andl the punch 85 will cut out a portion of the tape to form a washer and carry it forward for a. purpose which will appear later.

Aligned with the plunger is a cooperating reciprocating plunger 100 slidably mounted in the frame of the machine. J ust beneath the plunger 100 is a smaller plunger 101 corresponding to the plunger 82. These two plungers are actuated from the main shaft 3 through beveled gears 102 and 103 best shown in Figure 3. The bevel 103 is mounted upon ashaft 104 suitablyT journalled in the frame of the machine and this shaft carries a crank arm 105 which is connected by a connecting rod 106 with a block 107 secured to the plunger 100. The plunger 101 is suitably connected with the plunger 100. At each revolution of the main shaft 3 the plungers 100 and 101 are moved forward and back as in the case of the other plungers.

The end of the plunger 100 forms a punch 109 while the end of the plunger 101 carries a punch 110. A die plate 111 is rigidly mounted upon the machine and is provided with a hole 112 to cooperate with the punch 109. 1t is also provided with a smaller hole 113 to cooperate with the punch 110. Between the die plate 111 and the ends of the plungers is a guide plate 114 which forms a channel 115 through which a strip of tape 116 is drawn by suitable feed rolls.

lVithin the punch 109 is a pin or rod 117 which is free to slide therein and is pressed normally outward by a spring 118. This spring is best shown in Figure 6 which is a horizontal section through the center line of the plunger 100. It is desired to have the pin 117 projected from the punch 109 at the beginning of the cycle of operation of the machine for purposes which will hereinafter appear. Suitable means are therefore provided to release the pin upon the start of operation; the same being herein shown as a trigger mechanism best illustrated in Figure 6. Attached to a fixed abuemcnt is an arm 119 pivoted at 120 and free to rotate only in a clockwise direction on the pivot from the position shown. Pivoted at 121 within the )lunger is a trigger 122 which has an outwar ly projecting arm 123 carrying an upstanding pin 124. The plunger 100 is shown in its completely retracted position in Figure 6. Upon forward movement of the plunger the pin 124 will contact with a cam surface 125 of a cam plate 126 fastened to the underside of the arm 119. The arm being restrained from movement toward the punch, the trigger will be drawn away from the enlarged end of the pin 117 and the pin will be released and shot forward by the spring 118. As the plunger moves forward the pin 124 will move along the cani plate 126 until the arm 123 contacts with a spring 127 which tends to hold the arm 119 in the position shown. At this time the end of the pin 117 will have come in contact with the advancing anvil on the plunger 80 and be held from further forward movement so that the relative movement of the pin 117 with respect to the plunger 100 will be toward the right to compress the spring 118. Therefore as the plunger progresses further toward the left, the trigger 122 will bear against the enlarged end of of the pin 117 and finally snap behind the enlarged end so that the relative position of the plunger, pin and trigger will be the same as that shown in Figure 6. At about this time the plunger will be retracted from its advanced position and the pin 124 on the trigger arm will pass under the arm 119 and contact with the cam surface 128 on the cani plate 126. The arm 119 will be rotated slightly in a clockwise direct-ion during the retractile movement of the punch until the parts come substantially into the position shown in Figure 6 when the arm 119, urged by the spring 127 will snap back into the position shown.

Means are provided for drawing the tape 116 through the channel 115 and are substantially similar to corresl'ionding means acting upon the other tapes. The tape roll 130, Figure 1, is supported upon a spindle 131 attached to one of the standards of the machine and the tape is drawn from this roll through the channel, over a guide roll 132 and between feeding rolls 133 and 134. The feed roll 133 is mounted upon a shaft 135 which is joui-nailed in sliding bearings so that the feed rolls may be brought together by set screws 136.

As in the case of feed rolls 91 and 46, suitable means are provided for intermittently rotating the feed roll 133 to feed the tape step by step. A ratchet 137 is fast to the shaft 135 and a spring pressed pawl 138 mounted upon an arm 139 is actuated through a suitable link connection 140 from an arm 141 carried by a standard 142. The arm 141 has a roller 143 contacting with a cam 144 upon the main shaft 3 and the roller is maintained in contact with the cam by a spring 145. Eyelet feeding means substantially like that described in connection with the punch`35 are utilized to position an eyelet in front of the punch 109. The eyelet feed box 150 is driven through belts 151 and 62 the former running over pulleys 152 and 153. A gutter 154 leads from the eyelet boX to tlie'hinged gates 155 which position the eyelet at the'axis of the pin117.

An escape'ment mechanism similar to that operating upon the eyelets in the gutter 70 is provided to operate upon eyelets in the gutter 1.54. shown in Figure 15 and the link connections 157 to an arm 156 upon the arm 141.

The operation of the parts just described may be understood from Figure 5. First with respect to the anvil carrying plunger 80. It will be observed that upon reciprooation this plunger will movetoward the tape 89; the anvil pin passing` through a hole in the tape which has been punched at the previous operation yby the punch 86. The end of rthe, plunger 80 coming into contact with the tape will punch out a portion of the tape to rform a washer rand carry it forward.

Upon the other side. the initial movement of the plunger 100 will operate to release the pin 117 which will be moved forward,

passed through an eyelet, which is positioned in front of it, through afhole in the tape 116 which has been punched in the previous operation by thefpuneh 110 and will come in contact with the anvil pin 65 before the plunger 110 has travelled `very far. During further forward movement of the plunger 100 the string feedingmeans, which are about to be described, may operate. Upon further movement the punch 109 will open the gates 155, pass the guide 114 and Contact with the tape 116, cutting outa portion to form a washer and carrying the eyelet and washer forward to the ycentral position. The plunger- s 80 and 100 thus form the washers or buttons and position them against opposite sides of the flap oryblanlr, and the actuation of the plungers not only forms the washers andk positions them against the envelope. but also sets the eyelet which serves as a fastener by which the washers are afiiXe-d to the envelope flap. The description of the completion of the operation will be reserved until the string feeding means has been described.

The attachment of the stringl to the itiap of the envelope is preferably effected by looping the string around the pin 1.17 before An escapement bar 1.56 is `gear in the absence of any control thereof by Y thereafter caught between the envelope 'Hap and the reinforcing washer and firmly held there by the flanges of the eyelet.

Means for accomplishingV this result are herein shown as a hollow gear 200 mounted. within a suitable housing and' rotatingconcentricallyabout the pin 117 and of suficient size to permit the pun'ch109 to pass therethrough. This gear is rotated from the main shaft 3 by a suitable train of gearing comprising the gears 201, 202'and 203 and is preferably rotated at a greater speed than the main shaft. 1n this instance the gear 200 which, with its associated parts` rwill hereinafter be termed the looper makes four revolutions to one revolution of the main shaft. Means are provided on the gear to grasp the end of a string which is presented to the loop'er by means hereinafter described, the string graspingmeans being herein shown as a substantially U-shaped member 204, Figure 20, normally spring pressed against the face of the gear but adapted tov be extended from the face of the gear at the proper moment in the operation of the machine when it is desired to grasp a piece of stringpresented thereto.` This U- shaped member 204 extends through the gear and is fixed to a ring 205 having cam surface 206. The construction of this looper will be more readily seen from Figures 19, 20 and 21 which are respectively an end view, front view and cross-section of the looper. The ring 205 is normally held away from the gear by springs 207 and its movement is limit-ed bythe string engaging member 204. Thus, it will he seen that when an end of a string is placed under the member 204, it will be firmly grasped "between this member 204 and the face of the the ring 205 with its cam surface 206.

Means may be provided to control the opening and closing of the member 204 for the purpose of threading the string thereunder, the said means being herein sho-wn as a cam'208 mounted upon a lever 200 and kcont-rolled by a cam 210 upon the main shaft (see Figure 15). As this particular mechanism is designed to operate, it is desirable to have the looper opened for grasping the string once in its four revolutions,rth'at is.' at a time when the pin 11T yis extended. 1t will therefore be seenthat when the cam 208 is brought to the position .shown in Figure 15, the looper, rotating in a counterclockwise direction' willbe opened by the cam 208 for threading the string. As the looper continues to rotate the high point ot the cam surface 206 is rotated past the cam 208 and the string engaging member' 204 will grasp the string end which has been presented to it and will wind the string about the pin 117 until the string is released or withdrawn 'from the looper.

Means may be provided to present the end of a string to the looper mechanism so that it mav be engaged by the member 204 and the rim ot the gear 200, the same being herein shown as a reciprocating string carry# ing member 215 and its associated parts. This string carrying member is provided with a linger 216 having a resilient side plate 21'( to engage the string when it is threaded therethrough and to tension the string during the succeeding operations. The string carrying member 215 is mounted in a guideway 21S and is reciprocated by a crank arm 219 and link 220. the crank arm being mounted upon a shat't 221 which in this particular instance, is driven in synchronism with the main shaft 3 through a train of gears 222,

Means may be provided to sever the string, the same being herein shown as shears 230 having a lined blade 231 and movable blade 232 and mounted upon an oscillating member 233 pivoted at 234 upon the guideway. The two blades oit' the shears are -pivoted at 235 and are held in operative relation by anyr suitable means herein shown as a stud and spring 236. Suitable means may be provided to bring the shears intoY position tor cutting the string, the same being herein shown as a cam 23T upon the oscillating shears mounting adapted to be engaged by an anti-Friction roller 233 upon the string carrying member 215 to oscillate the shears and bring them into operative position tor cutting the string. The shears mounting is shown in its normal position in Figures 15 and 17 and is yieldingly held in this position bv a spring 239 attached to the shears mounting and to an arm 240 which in turn is rigidly attached to the guideway 218.

Means may be provided to operate the shears to cause them to ont the string upon their being brought forward through the aperture 241 in the guideway, such means being herein shown as an anti-'friction roller 242 upon the rearwardly extending movable blade 232 of the shears. (See Figures 1'? and 1S). This roller 242 vis adapted to be engaged by a pair ot cams 243 and 244 which cause the shears to close and open respectively. l t will be observed that when the shears mounting is oscillated upon the pivot 234 the shears will be swung` forward until the anti-friction roller 242 contacts with the cam 243. Upon further Vtoi-wind nlovement of the shears the cam 243 will 223, 9.2i-, asa and Q27;

operate to bring the cutting edges ot the shears together and thereupon the machine being so organized as to bring the string between these cutting edges, the string will be severed just above the threader. As the string carrying member is moved upward by the crank and link connection with the. shaft 221 the roller 233 upon the string carrying member will be released from engagement with the cam 237 upon the shears mounting and allow the same to resume its normal position under the action of the spring 239. The rearward movement of the shears will bring the shears operating roller 242 in contact with the cam 244 which will cause the shears to be opened in readiness for the next forward movement preceding the cutting of the next length of string.

To assist in properly locating the envelope an adjustable table 250, as shown best in Figures l and 2, is positioned in front ot the machine and supported in a bracket 251. rllhis table may be raised or lowered by means of a screw 252 which can be rotated by a handle 253. The screw is threaded in a bracket 254. The table may be adjusted to a proper horizontal plane b v another screw 255 shown in Figure 2.

The operation ot the machine as a whole may be summarized as follows: Starting with the several parts of the apparatus in thc positions shown in Figures 1. 27 4 and 5, and referring particularly to those ligures` an envelope to which the string closure is to be Vatlixed may be inserted in the machine b'v extending the Hap into the space between the die plate S4 and the looper 200; the shoe 2O being inserted in the envelope that the bod;v ot the envelope comes between the shoe 2() and the die plate 30. The table 2:10 will of course be previouslY adjusted lo position the envelope properly. The envolope being in place the treadle 15 ma)v be depressed to release the clutch mechanism and start the rotation of the main shatt 3. The several plungers will start their torward movement at a relative speed depending upon the distance. which they have to travel. The initial movement et' trie plunger will release the pin 11T and shoot it forward into contact with the envelope tlap. The initial rotation of the string looper will cause it to grasp the string and wind the string about the pin while. the several plungers are coming forward. Vhen the main shaft has made substantially one quarter revolution the several punches will have reached their respective tapes and cut out washers therefrom. Yin the case of the plunger 100 the punch will carry *forward an elvelet and washer upon the pin 11'?. while the plunger 8O cuts out and carries 'forward a reinforcing washer on the anvil pin 83, and the punch 35 cuts out and carries t'orward a washer and eyelet upon the pin When you Cil

the main shaft has completed about the Vfirst half of its revolution, the punch 35 will have a Washer and eyelet `in Contact `With the body of the envelope. the anvil'85 Will hold the reinforcing` Washer `incontact with the iiiside of the flap of the envelope and the punch 109 will hold a fastening Washer and eyelet in Contact 4with the outside of the flap ofthe envelope, while the string will be Wound upon the pin 11T and when the eyelet on the pin has advanced `far enough the string will ride up upon the shank ofthe eyelet.

During this time the string carrier 215 will have descended in its guide-Wjay until-the roller 238 is nearly in contact With the cam 235 of the shears mechanism. At the completion of the first half revolution the punch 35 Will force the e-yelet carried by it through the paper of the body 0f the envelope and upset itl against the anvil thus securing the fastening washer to the body of the envelope, ivhile the cooperating plungers 8O and 100 will force an eyelet through the fasteningand reinforcing,Washers andthe fiap of lthe envelope and upset it to secure the Washers and stringfirmlythereto. At substantially this time the shears ivillbe moved forward to cut the string at the proper point.

During thesecond half revolution ofthe main shaft the several plungers ivill be retracted to their starting positions, the tapes advanced one step and an eyelctdropped to the bottom ofveach gutter, and the stringiv carrier will'have returned to the position of Figure 5 to place an end of the string Where it can be graspedby the looper. This conr pletes a single cycle operation and places the machine in position for its neXt oper-k be variously modified and embodied Within the scope of the sub-joined claims.
