The opposite end of the feed roller 287 is journaled in an arm 289 pivoted'at 290 to'the table 279 and having pivoted at its free end a lever 291 provided at its lower end with a cam face 108 so that when said lever is actuated the enlarged diameter 293 of the feed roller 287 Will be raised, so that the stamps which are guided in the groove member or uide 294 may be passed under said enlarged diameter 293 of the feed roller 287.

In order to maintain the lever 291 in the adjusted position given thereto, I provide a spring 295 which is pivoted at one end at a suitable point to the table 279, its free end engaging the pivot pin 292 on which the lever 291 is mounted.

296 designates a spring secured at one end to the table 27 9, the other or free end thereof being in alinementwith the stamp guide 294, so'that as the stamps pass between the feed members 287 and 27S, any'deflection 01' imroper movement is positively prevented. lhe spring 296 exerts a yielding pressure on the stamps which are bein fed, so that the stamp next to the stamp w rich is beingsevered will not be advanced during the-severing operation. 297 designates his 279 in .Which and 299, said brackets carried by the taare journaled the rods 298 rods having secured thereto in any suitable manner, a block 300 to which is adjustably secured a depending arm 301 which engages a cam block 302 adjustablv mounted on the shaft 266, said cam block having the release face 303, whereby the

308 designates a presser iece pivotally carried by therod 306 and iiaving a uide pin 309 which engages the side of the lrnife member 304.

In order to insure the envelops being placed in roper position upon the stamp )ed 310 0 the machine which may, if de sired, be formed of a continuation of the table or support 279, I mount on the shaft 266 a cam block 311 provided with a release face 312, which co-acts with a lever or cam member 313 adjustably mounted on a rod 314 journaled in a bracket 315 carried by the machine in any suitable manner as most clearly indicated in Fig. 3.

316 designates a set collar adjustably mountedlon the rod 314 between which and a fixed point on a bracket 315 is interposed a spring 31.7, whereby the lever or cam member 313 is always maintained in engagement with the cam block 311.

The end of the rod 314 has adjustably secured thereto a 'rod 318 which is secured at one end of a lever 319 fulcrumed at 320 to a suitable fixed point of the'machine frame.

The lever 319 has secured at its outer end 1 an upwardly extending arm 321, the upper end of which is serrated and deflected rear-- the bed 280, the outer or free end of said guide 322 being deflected upwardly as clearly indicated in the drawings, it being also noted that the forward movement of the envelop is limited by the table 27 9.

323 designates a roller mounted in a bracket 324 preferably carried by the stamp guide member 29 1, as seen in Fig. 9, whereby the strips of stamps ma be wound on said roller 323 if desired an passed through or over a uide 325 and thereby to the feeding rollers for the stamp, as clearly indicated in said Fig. 9.

Mechanism for removing the stamped envelo s from the bed..326 designates a cam bloc mounted on a sleeve 327 carried by the shaft 266, it being noted that the cam member 326 is provided with a release face 328 with which a cam member 329 co-acts, said menil'ier being mounted on a shaft330carried by an arm 33] carried by any suitable. The shaft portion of the machine frame. 330 has mounted thereon, a lever arm 332, the upper end of which is deflected, as'clearl y seen 111 Figs. 1 and 4 of the drawings The shaft 331') is provided with ,a torsional spring- 333, whereby the cam member 329 is maintained in engagement with the cam member ing table 19 326, as indicated in Fig. 1 of the drawings, it being seen in Fig. 3 that the bed 310 is suitably cut away or recessed as seen at 334, in order to provide for the movement of said lever.

335 designates a plate carried by the de ending arm 283 which engages a groove 336 in a set collar 337 keyed onthesleeve 327, as clearly indicated in Fig. 1. v

The operation of the machine will now be readily apparent to those skilled in this art.

, I will first describethe manner in which the the side of the machine, so that the envelope maybe the more readily laced in proper posi@ tion for being fed into t e machine, as most" clearly indicated in Fig. 18, it being notw that the guides 36 and 39 serve for t' 5 lateral adjustment of the envelops and the guide members 33 serve for the longitudinal adjustment of the envelops. In the pre it instance, I have shown the driving sh;v 4 as being providedwith a handle 339, whereb the same may be manually actuated, a.-

though it is to be understood that in the broad scope of my invention, it is immaterial in what manner the driving shaft is driven and the same may be actuated either manually as shown or by means of any suitable or conventional type of motor or driving mechanism, as will be readily apparent. On the rotation of the driving shaft 4, the gear 6 car ried thereby, owing to the provision of the crank arm 3 and the manner in which it is secured to said gear, will cause the shaft 11 to be rocked forwardly, it being noted that the connecting arm 8 is adjustably secured in the slot 12 of the link 10 which latter is secured to the shaft-11. Since the shaft 11 has secured thereto the arms 14 which carry at their outer end the roller 17 engaging the arms or fork 18 de ending from the envelop feed table or 'mem )er 19, the latter will be carried forwardly as the shaft 11 is rocked. 'lhe envclo s normally rest on the flanges 31 of the tab e 19 and the feeding lingers or members 31), and owing to the manner in which the flanges 31 are cut away, as seen at 32 in Figs. 11 and 17, the [lap of the lowermost envelop will assume the position. as indicated in said Fig. 11, it being understood that the envel'o )8 when placed in position are placed one-'alwove the other with the flap portion of the envelop underneath and with the flap of the envelops nearest to the feeding the cam face 24 on the weighted end ZS-of said lever and inclined cam face 23 on the ways 21, the ends of the levers26 to which v the feeding members 30 are secured will cause the ends of said members to move downwardly, so that the envelop will pass between the lower ends of the pawl 72 and the top face of the flanges 31, it being noted that owing to the manner in which these on t pawls are pivoted and the tension device the engagement of the members .30 with the 4 flap thereof, will pass in an accurate manner to the

feed rollers

56 and 57.

As most clearlyindicated in Fig. 5, the driving gear 6 actuates the gear 42, which in turn actuates the gear which meshes with the gear 47 mounted on the shaft in which the lower feed roller is secured, said gear. 47 meshing with the gear 49 mounted on the upper shaft 50 to which the upper feed roller 57 is secured, so that the advancing envelop passes between the feed rollers 61 and 62, as will be apparent from the drawings. The feed roller 61 is mounted on a shaft 59 on which latter is also mounted a gear 60wliich meshes with a gear 58 carried by the shaft 46.

. The envelop after passing from the'rollers 61 and 62 falls on thefguide members 89 mounted on the rock sha. t

shaft on which is also mounted the cam member 81 with which coacts the roller 83 carried by the bracket 84 and secured to the.

shaft 85 on which the guide members 89 are mounted, so that as the shaft 80 rotates in unison with the rotation of the driving shaft 4, the guide members 89 will be rocked and the envelop supported thereon will slide from said guidin members and engaging the guide plate 91 wi l he deflected downwardly as in dicated in Fig. 11 towards the moistening device for the flap of the, envelop. At this time, owing to the provision of the cam memher 162 and the construction of the arm 98 coacting therewith, the hooks or catches 99 will at this time be in the position indicated I in Fig. 12 and the descending envelo will be received thereon as clearly indicate in said figure.

As indicated most clearly in Fig. 5, the shaft 43 is rotated by means of the gear 42 meshing with the drive gear 6 and owing to the provision of the cam member 102 and the manner in which its operative surface is cut away, as this shaft rotates, the arm 98 meeting with said cam will be moved uickly rearwardly so that the envelop may second and be engaged by the flanges 94 and .of.

the moistenin and feed rollers 92 and. 93; and fed downwar .ly thereby.

p 85. The driving gear 6 meshes with the gear 79 mounted on the Mecmsfor opening the flap of the encelop. The flap of the envelop is now opened in the following manner:-As seen most clearly in Figs. 1, 10, and 3, the cam block 158 is mounted on the driving shaft 4 and rotates in unison therewith.v The operative cam surface 157 on the side of said cam block coacts with the roller 156 carried by the arm 156 which is secured to the sleeve 153,- mounted on the rod 152. As clearly indicated in the drawings, the arm 154 engages the pin 148 and normally maintains the plate 150 in its rearmost position. As the shaft 4 rotates the cam member 158 will permit said arm 154 to turn on its pivot and owin to the provision of the spring "146 the plate 150 will be moved forwardly and engage the envelop, as most clearly indicated in Fig. 10. The envelop is now being fed downwardly between the moistening rollers and owing to the position of the plate or blade 150 thefla of the envelop-will be opened, as

most 0 early indicatedun Fig. 14. 'It is, of course, to be understood that'before the machine is set in operation the handle 136 is actuated to rotate the shaft and owing to the provision of the cam blocks which coact with the depending 'members:

and be moistened thereby as the envelop is.

bein fed downwardly by the enga ement of theanges of the rollers 92 and 93 t erewith. As the envelop passes from the moistemng 184 an'dfthe plates 178, as most clearly indicated in Fig. 15, it being understood that the parts are now in the position as indicated in said figure.

Jlleansfor bending lhejlap ofthe envelop be fore it passes to the sealing rollers-The gear 6 mounteirl on the driving. shaft 4 coacts wlth the gear165 mounted on the shaft 164 on which is also'mounted the cam member 163 with which the roller 162 is maintained in en gagement by means of thespring 171 secured at the outer end of the elbowlever 1 61 on which said roller is mounted. The roller 166 carried by the elbow lever 161 and'enga mg the groove 167 in the arm 168 will cause t e shaft 169 on whichit is mounted to be rocked for "Wardly." As the shaft 169 is rocked, the shaft will also be rocked owing to the provision of the cam member 186 adjustably carried by the block and since this member is de flectcd downwardly as the same moves, on

the roller 1-87 journaled at 188' it will cause the said shaft 186 to be locked forwardly and 105 rollers 92 and93, it'is guided by the members f 131 so-that the same passes between the arms the bracket 189 carried thereby will be moved. downwardly, as indicated most clearly in Fig. 16, it belng noted that owing to the pro- .vision of the cam faces 201 and 202 this movement is permitted and the cam face 201 will limit the rearward movement of said bracket 189. The plate 192 which is pi-vo ted at 191 on the bracket 1-90 will be carried downwardly bythe arm or bracket 189 and owing to the location of this pivoted member it will engage the flap of the envelop, as clearly indicated in Fig. 16 and cause the same to be deflected downwardly.

llleansforfeeding'the envelope to the sealing rollers-The envelop is now fed between the sealing rollers. Referring to Figs. 1 and 5, it will be seen that owing to the provision of the roller 203 coacting with the cam 204 carried by the shaft 205 and the roller 194 carried by said lever. 193 and engaging the slot 195 in the arm 196, the shaft 197 will be rocked forwardly and thus cause the arms 198 to turn on their fulcrum 197 and the envelop will be moved forwardly into engagement with the sealing

rollers

210 and 211, as most clearly indicated in Fig. 11, it being noted that owing to the manner in which the plate 192 is pivoted that this does not prevent in any manner the passage of the envelop to the sealing rollers. The envelop passes from the sealing

rollers

210 and 211 to the second set of sealing rollers 219 and220 which latter are driven by means of the idler 206 which meshes with the gear 208 mounted. on the shaft 209, said gear 208 meshing with the gear 165 driven bythe' gear 6, as may be clearlyunderstood from Fig. 5.

Means or'moz'sten i'ng the stamp receiving portion of the eatelop.-As seen in Fig. 2, the collar or bracket 226 is mounted on the shaft 43 and this collar has extending therefrom an arm 227, as seen in Fig. 3, n'ovided with av depending lug or ram 228 w li('l1 roacts with the ('am block 229 carried by the driving shaft 4, so that as said cam is rotated the arm 227-will be lowered and raised at a predetermined time. The lever arm 235 which is pivoted at one end, as at. 236, to a fixed portion of the frame, is operatively connected I by means of the link 22-12 with the end 230 of the lever227; it being noted that owing to the provision of the slot 233 in said link 2332 andf-the recess-231 on the lever 227 that this link may be readily disengaged when desired. As the envelop passes beneath the stamp moistening device 248, the same is lowered owing to the provision of the ram or lug 228 and the coarting cam block 229 mounted on the shaft 4, so that the absorbent or other material 25 1 engages that portion of the envelop on which the stamp is to be placed.

Referring now to Fi 5, it will be seen that the driving gear 6 mes ies with the gear 165, which in turn meshes with the gear 208, which drives the idler 206, which latter meshes with.

the gear 260 to which the bracket or casing 262 is eccentrically secured so that the rack arm' 263 is reciprocated. The rack arm. 263 00- acts with the pinion 265 to which latter is secured the member 267 which. carries the pawl 268 and owing to the provision of the shoulder 27 on the inner periphery of the collar or sleeve 271 it will be understood that as the'rack arm travels forwardly the shaft 266 does not rotate since the pawl 26S moves freelywithin the collar or sleeve 271. On the further rotation of the gear 260 it will be apparent that the arm 263 will begin to move rearwardly and as this rack arm moves rearwardly and rotates the pinion 265 the pawl 268 will engage the shoulder 272 of the collar or sleeve 271 and since this sleeve is fixed to the said shaft 266 this shaft will be caused to rotate. As the shaft 266 rotates the cam block 273 will rotate in unison there. with and as the cam block coacts with the roller 274 carried by the bracket 275 secured to the shaft 259, said shaft will be rocked, as is apparent from Figs. 1 and 4. This will cause the arm 258 to be raised. and engage the lower end of the plate 257 and cause said plate to be moved upwardly so that the envelop will be pressed against the absorbent or other material 251 carried bythe moistening device 248.

Means for passing the rnvelopfrom thefeecl rollers into POS LllO'YL to be stampcd-Tho envelop is now passet position to be stain )ed. Owing to the provision of the cam b ock 311 having the release face 312 thereon and. mounted on the shaft 266, as this release fare passes beyond the arm or cam member 213, said member will be permitted to more rearwardly togither with the rod 314 to which it is secured owing to the provision of the spring 317 interposed between said collar 316 and the fixed portion of the bracket 315, as'most clearly indicated in Fig. 3 This will cause the lever 319 to operate the rod or pin 31S carried by the member 314 thusrausing the serrated arm 321 carried by said lever 319 to move forwardly and thus move the envelo on to the table or support-I510and beneath the stamping device. i

illea'ns for feeding tlte stamps into proper position cheer the wn,rel0p.-The stamps are fed into the machine through or over the guide nimnber 29-1, said stamps being prefer ably upon a suitable roller 323, as indica {d in ig. 9. The shaft 266 carries a geai'276 which meshes with a gear 277 mounted on a shaft 278, a port ion of. which forms the lower T he shaft 272% is provided with-a. pin-ion'285 which meshes with apinion g2-86 carried by the upper feed member 287;"which is pro vided in the present instance with an enlarged diameter 29.), lower feed roller, so that as the she which :coacts wi h the ,neath the severing member 304 and the rotated the

feed members

278 and 287 will also be rotated sothat the stamp is fed,be

' gages the release face 303 of the cam block 302, said shaft will be rocked, it being noted,

- as seen in Fig. 3, that a spring is mounted on the shaft 298, so that there is always a tension tending to rotate said shaft and maintain said arm 301 in engagement with the coacting cam member 302 As the shaft 299 is rotated, the arm 304 will be caused to turn on its pivot and since this arm is provided near its outer end with a suitable knife member or severing blade, as the outer :end of which arm 304 moves downwardl thestamp will be severed from the strip an on the further movement of said arm the presser memher 308, which is pivotally mounted on the rod 306 carried by the bracket 305, will press the stam firmly against the envelop. The

' envelop as now been sealed and stamped and is end of the envelop and cause'the same to he I ready to be discharged from the machine.

Means for discharging the envelope from the machine.'lheshaft 266 has also mounted thereon a sleeve327 on which is mounted a cam block 326, said cammember 326-being rovi led with the release face 328 with Whic a cam member 329 coacts, so that as the shaft 26B is rotated the ,shaft' 330 to which said cam member 329 is secured will be rocked andthe 11 per end of the arm 322 carried by said sha t 330 will engage one passed or thrown out of the machine in a very positive andeffective manner, it being" noted that the cam member 329- is always maintained in o erative relation with re-- 'spect to the cam lock 3 26 owing to the provision of the spring 333 mounted on the may be adjusted. The-machine may be shaft 330. i a
