In said drawings, 1 indicates a base or .bed plate upon which the different parts of my improved machine are mounted. At one side of this base plate is a horizontally and longitudinally disposed belt 2, which runs over drums 3, 4, at opposite ends of the plate, the drum at the rearward end being mounted upon a shaft- 5 having its hearings in posts 6, and the drum 4 at the front end of the-machine being mounted upon a shaft 7 turning in standards 8, 118, at opposite sides of the base plate 1. This belt serves at its upper part as'a carrier for the envelops, a feeding hopper 9 being arranged adj acent to the top of said belt at the rear end of the machine and the' stamping mechanism being located at the opposite or forward end. Adjacent to the said feeding hopper the fiap-moistening devices are arranged upon standard 10, and adjacent to the drum shaft 7 preferably at the opposite side of the bed.
plate from the belt 2, is arranged means for driving thesaid belt and thus the entire mechanism of the device. Said motive means comprise a shaft 11 journaled in posts 12, 12, extending upward from the base plate, said shaft having a pulley or wheel 13 which may be rotated by a handle 1 1 or any other suitable means. Said shaft 11 has also a pinion 15 meshing with a gear 16 mounted between posts 17 and which en-' gages a gear 18 on the shaft 7, (see Fig. 9). The said feeding hopper 9 is supported by posts 19 extending upward from the base plate on opposite sides of the belt 2, and oomprises'sides 20, 21, and a front 22 which is preferably inclined forwardly upward, the top and rear end being entirely open. The bottom of said feeding hopper is open except for a narrow ledge 23 at the side being carried forward on said belt by thefront end wall 22 of the hopper and a cer' tain gate thereon next to be described. This gate 25, referring more particularly to Figs. 2 and 36, is mounted upon the outer side of the front wall 22 of the hopper, near its bottom, and it is adapted to slide up and down against the belt surface to guard the slit or passage between said belt and certain fingers 26 mounted on the hopper, and which space is suflicient to permit a single letter to pass. I have shown said gate 25 as having slots 27 to receive studs 28 for the gate to slide on; coil springs 29,29 serve to normally hold the gate downward against the belt,
and a roller 30 is mounted upon the lower edge of the gateto preventits scraping upon an envelop passing through.
For raising the gate a shaft 31 is mounted adjacent to and outside of the same in brackets 32, 32depending from the hopper wall 22 and said shaftcarries "a lateral rearwardly projecting finger 33 which is adapted to take under a lifting piece 34; on the gate. At its outer end, the said shaft 31 has a crank arm 35 which is pivoted to the upturned extremity 36 of the forward arm 37 of a lever 38 fulcr'umed as at 39 on the outside of the low wall 21 of the hopper. The rearward arm 40 of thisv lever has an outwardly projecting stud 11 adapted to be en gaged by the cam-like surface 42 of a trip 13 shown more particularly in Figs..17 and 20, and forced upward thereby to swing the said lever 38 and open the gate 25 as will be understood. Said trip is .carried in a tripbox l4, shown also in Fig. 2, and several of which at proper intervals are fixed or mounted on the belt 2, at its outer edge, to travel with the same. In order to predetermine the release of letter at just the proper time, the stud 41 is made adjustable longitudinally of the lever 38 in a slot 15 of the same, and to provide access for this adjustment from the inside of the hopper its said low wall 21 is'also slotted as at 46. (See Figs. 3 and 4, also.)
Upon leaving the feeding hopper, the envelop is carried along between the belt 2 and roller 30, its flap being freely exposed downward by reason of the narrowness of the belt as has been above referred to. In this position a deflecting shoe 50 engages the said flap and turns it downwardly outward into vertical plane or beyond. This shoe is mounted upon a post 51 projecting upward from the base plate 1, and has a thin horizontal edge 52 to enter between the flap and body of the envelop, and a curved guiding face 53 to force said flap open, as shown in detail. in Figs. 5 and 6. Just beyond the said deflect-- ing shoe 50 are means for moistening the flap of the envelop when opened, comprising upper and lower rollers 54: and 55 mounted on the standard 10. The lower roller 55 is 3 peripherally recessed for a partof its length,
a shaft 58 both being journaled in the stand ard 10. and a collar 59, upon said hub outshaft 62 which also bears in a post 63 upon ecting therefrom.
the bed plate and carries a roller 64: beneath those 54, 55 already described, and which is engaged by the lower part of the belt 2 to rotate the shaft 62, as shown in Fig. 2. Upon the outer end of said shaft 62 is gear 65 which meshes into an inter ediate gear 66 to transmit motion to the gear 61 upon the shaft 58, as above described.
In the lower part of the open end of the drum or roller 55 is arranged a tank 67 which lies partly within the roller and partly pro- This tank has at its inner end an upward extension 68 provided with a long sleeve 600 which receives the shaft 58, between the standard 10 and a fixed collar 60, to support-the tank. At the open end of the said drum is mounted upon an approximately vertical shaft 69' a conical moistening roller 70, which lies partly within the drum in a transverse position with respect to the end thereof. The
said shaft 69 has hearings in a seat 71 upon the bed-plate and at a higher point ina bracket 72 on the bed-plate, and is driven by means of bevel gears 73, 74, from the shaft 62. This conical moistening roller 70 is inside the tank 67, and is hollow at its bottom part to receive a sleeve 75, which projects up from the bottom of the tank to afford a bearing around the shaft 69, and. to prevent escape of water from the tank. This roller 70, it will be understood, is adapted to engage at its sides the flap of an envelop passing through the machine and thus moisten the same, a paddle Wheel 76 in the tank 67, and mounted on the shaft 58, serving to throw water against the said moisteningroller 7 O to keep it continually wet. A shield 700 on the tank closes the open end of the drum around said roller 70. The envelop thus has its flap moistened while in opened position, and then the envelop passing onward by the motion of the belt 2, said flap is engaged at its outer or surface side I by the upright edge 78 of a shoe 77, which has a face 79 curving from said edge into a substantially horizontal plane at the other end of the shoe, as at 80, and thus adapted to close the flap of the envelop. This shoe 77 a is preferably mounted upona post 81 0n the bed-plate 1. After having its fiap closed as thus described, the envelop passes beneath the stamping devices and receives a stamp, as will be hereinafter set forth in detail. Then the envelop immediately passes between the end roller 4 for the belt and a machine, the pressure of said rollers serving to press both the flap and the stamp securely fast to the envelop. The said roller into the hollow end of the roller. (See Fig. 9.) A nut 831 on said stud at the outer side of the bracket removably secures the roller in place. This rcller S2 lies against the envelop from above at its discharge from the machine, direct-1y above the end roller 4 for the belt 2, and is provided with a yielding surface 821 of rubber or the like which will allow the envelop to pass between said rollers with pressure. The belt roller 4 is recessed to receive the belt 2,. so that the peripheral portion of itself which the beltdoes not extend over is flush with said belt and properly cotiperates with the upper roller 82, as will be understood. As an envelop leaves the flap-closing mechanism on its way to the stamping devices, the trip-box 6L4 which caused the discharge of said envelop from the hopper 9 sets the stamping mechanism in motion, as willnextbe described, and said mechanism is timed to apply a stamp to said envelop as it comes along, at ust the proper point. 4
, 82 rotates on a stud 83 secured in a bracket 84 mounted on the standard 8 and projecting A long shaft 85, extends transversely of 4 the machine with respect to the belt 2, and is journaled at its end farthest from said belt in a bearing 86 on the lower rear edge of a certain end guard 87 of the stamp supply cylinder hereinafter described', (see Fig. 33). This shaft 85 is capable of a limited longitudinal movement, for purposes present-ly to be set forth, and a leaf spring88 on the end of sai extremity of the shaft to normally hold it toward the belt 2. Another bearing for this shaft 85 is provided adjacent to the pathway of the envelops in the outer end of an arm 89, which extends forwardly in substantially horizontal position from a post 90, to which it is hinged to. swing up and down (see also Fig. 34). This allows the shaft 85 to raise and lower at its enlarged end 102 next the envelop belt 2, for purposes presently to be set forth, and a spring 91 bears on the said arm 89 to hold it downward, while an adjusting screw 92 beneath provides a limiting stop for the arm. The free end of said shaft 85 projects across the belt 2 and is adapted to be engaged by the trip and slid longitudinally as next described, particular reference being had to Figs. 1620, inclusive.
The trip box lt'at its inner side or side facing the belt provides between its overhanging top 93, and the belt 2, a vertical slide Way for the trip 43, said trip being mounted by headed bolts 94., 94, working in slots 95, of the box, and being normally held down against the belt by upper springs 96.
The inner face of this trip provides at iti upper part a channel 97 parallel to the belt 4 and the side walls of which are at their inner bearing presses against the surfaces beveled outwardly apart as at 98, 98'; furthermore, the inner face of the trip has on opposite sides of said channel 97 and adjacent thereto, inclines 99, 99 which slant rearwardly inward. The lower part of the trip is tapered equally from top and botton'i to a'sharp edge or point 101 at its front end, and provides .upper and low?" longitudinal bevels 42 and 100. This sharp edge 101 lies normally just enough higher than the said free end of the shaft 85 so that it will pass over the same and the trip only he idly pushed up, as shown in Fig. 17, to drop back into place again. But if there is a letter to be stain ed, its thickness in passing beneath" the sha t end 102 upon the belt 2, raises said shaft end sufliciently so that the lower part' of the trip passes beneath said shaft end and the same is accordingly lifted into the channel 97 of the trip.
In order to more accurately determine whether the shaft end shall pass above or below the lower part of the trip 48 the beveled forward end of said trip is divided on a vertical planelongitudinally of the belt, as at 104:, into a thin inner portion having a long taper 106, and a thicker outer portion 107 having a more abrupt taper. The end 102 of the shaft 85 does not reach inward to the long taper, but said end is provided with a needle point 108 which passes either above or below the long tapered edge, according as an envelop is on the belt or not. This needle having primarily determined which way the parts are to engage, the shaft end immediately impinges upon the outer bevel (either upper or lower) to take the strain of engagement. When the shaft passes through the channel 97 of the trip its shoulders 109 adjacent to the engaging end 102, bear against the inclined surfaces 99, 99, and the shaft is accordingly shown in Fig. 1.
pushed longitudinally. As shown, the trip box is not rigid enough to take the reaction of this, but is reinforced by an adjacent parallel portion 110 of the standard 8 as This longitudinal movement of the shaft 85, which is always receiving rotary movement through a gear 111 on itself engaging anot er gear 112 on an auxiliary shaft 113, which in turn carries a second gear 114 meshing with the said gear 16, (see Figs. 34 and 35) throws into engagementa clutch 115 on the shaft so that a gear 116 thereon transmits motion to the stamp supplying c vlinder. This cylinder. referring more particularly to Figs. 1 .and 12, is mounted at the forward end of the ma- I chine in transverse position with respect to the belt, fast upon a shaft 117 which is ioun naled at one end of the standard 8 and at the other end in another standard 118. The cylinder proper is designated by reference numeral 119 and comprises end disks 120 121 having central bearings for the shaft 117, and'a cylindrical shell 122 secured thereto, one of the said end disks, as 121, having its periphery toothed as at 123 to be engaged by the said gear 110 and receive rotation. This cylinder 119 is designed to carry upon its-surface a sheet of postage stamps such as is obtainable at any post-office, said sheet lying upon the cylinder with its guinmed surface outward, the long sides of the individual stamps extending longitudinally of the cylinder, and their bottom edges toward thebelt 2, in order that the stamps be put onto the envelops right side up. The cylin der is to supply or feed the stamps one by one to-the envelops as they go through the machine.
Longitudinal clips 180 (see Fig. 15) are provided upon the cylinder 119 to retain the edges of the sheet of stamps, and said cylinder also carries holding hands 121 and a feed ng ring 125 to otherwise secure the sheet.
Said feeding ring 125 is farthest from the'belt 2, and has a body portion 126 encircling the cylinder 119 and. an inner radial arm 127 projecting through a longitudinal slot 128 in the bottom of the cylinder which therefore permits sliding of the ring 125, the end of said slot 128 serving asa stop to keep the ring away from the gear 123. Said arm is apertured at its end to receive the axial shaft 117 of the cylinder, and also near the circumferential body of the ring to receive a rod 129 extending longitudinally of the cylinder and mounted ini ts end pieces 120, 121.- These bearings prevent rotation of the ring on the cylinder, and give it an even sliding movement thereon. At its side next the belt 2, the said ring has a hin .sheetmetal extension 130 fitting the cylinder and a stepped end 131 which allows suflicient space between it and the drum to accommodate the sheet of stamps. Between said ring 125.and the end of the cylinder next to the belt 2 are a plurality of holding hands 124, each-of which surrounds the cyl inder and has an inner radial arm 118 lyin in theslot 128 of the cylinder and aperture to have bearings upon both the rod 129 andv the shaft 117, like the end ring described.
These bands are adapted to be slid .any-
'where on the cylinder that they are needed to confine a sheet of stamps, and are provided with inner radial projections 134: to engage the sheet at intervals, the extension of the end ring being recessed or slotted as at 135 to receive such projections and thus permit the bands tobe all picked up by the and ring as it approaches the end of the cylinder next to the belt 2. Preferably, each band 124. has a friction spring 132 seated in a socket and confined by a screw plug to bear against the rod and prevent undue freedom in sliding. At the bottonrof the end ring 125 is ashoe 136 which straddles a fixed bracket or track 137 beneath .the cylnider 119 and has flanges 138 which loosely I embrace the T-riin 139 of 'the end ring, whereby said end ring is free to turn but must move longitudinally with the said shoe to feed the sheet of stamps endwise of the cylinder when one circumferential row is used up and bring the next row into position. Between the halves of the said bracketis a vertically slidable bar 149 normally held upward by springs 140, and having in its upper edge notches 141 to receive a tooth 142 on the shoe','said notches being spaced to correspond to the Width of the circumferential rows of stamps or length of an individual stamp. By momentarily depressing the bar, the end ring is allowed to be drawn one notch forwar b cords 143 extending over pulleys 144, to a drum with tensionsprings 145, as will be understood. v
The depressing means comprises a lever 146 fulcruined as at 147 on a stud 148, one end of said lever bei-n pivoted to the middle of said bar 149 311C? the other end adapt ed to bepushed upward by a cam 150 on a sleeve 151 of the shaft 7, which carries the belt roller 4. (See Figs. 9 and 29.) For convenience, the end of said lever 146 is bifurcated as shown in Figs. 29 and 31, and carries a cross piece upon which a friction roller 156 is mounted to engage the cam 150. Said sleeve carrying the cam 150, generally Stands still or idle upon the shaft 7, but is provided with a clutch member 152 to engage a cooperating member153 on-the shaft itself and which shaft continually turns, as will be remembered; It is desired to engage the said clutch members and thus. operate the cam and feed the sheet of stamps longitudinally of the cylinder, as soon as one circumferential row of stamps has been used up or fed to theenvelops by the rotation of the cylinder. Therefore, a cam 154 is arranged upon the outside of the end disks 121 of the cylinder 119 at such a point that when the cylinder has turned far enough to completely discharge a circumferential. row of stamps, its continued turning engages said cam 154 with the upper end of a forked lever 155, fulcrumed on the bracket ,137 astraddle of the same andengaging at its lower end the sleeve 151 inthe usual inannerto slide its clutch member 152 thereon into engagement with. the driving clutch member 153. In this connection, it should be noted that the sheet of stamps does not reach clear around the cylinder, but a considerable gap occurs between the clips 180, 180, (see Fig. 15). Time is thus given for shifting the sheet lengthwise of 'the cylinder, before the newly placed circumferential row begins to be fed out.
Contiguous to the end next the belt belt to be of the cylinder 119 2,'and in fact overlying said in alinement with that part of an pivoted to the arms,
platen head,
envelop thereon where the stamp should be affixed, (see Fig. 1), is a cylindrical platen head 160, of equal diameter withthe cyl nder and preferably wide enough for the circumferential row of stamps being fed, to he wholly thereon. This platen head 160 does not rotate, but is held in fixed sleeve 161, on the shaft 7 bolted to the stand- "ard 8, and connected to the closed outer end 162 of the platen head 160, its end next the cylinder being open (see Fig. 12). Overlapping the surface of said platen head' 160 and projecting from its outer end inward,
are segmentalshields 163 (see Figs 27' and 28), which normally lie at a little distance away from said platen surface and parallel thereto, so as tp provide a slide way or space between for the stamps. Each shield 163 is hinged to the end edge of the platen head 160, as by means of a plate 164, and has an arm 165 projecting endwise from the platen head 160, so that they can all be raised or opened outwardly away from the platen head surface, as shown in dotted lines in'Fig. 28, to allow the placing of a new sheet of stamps on the cylinder with facility. For securing greater convenience by enabling all the said shields to be opened and closed together, I have provided the means shown more in detail in Figs. 27 and 28, where 166 indicates a segmental disk rotatably mounted on the sleeve 161, and having eccentric slots 167, each of which receives a pin 168011 a connecting strip 169 extending radially outwardto one of the segmental shields 163, Preferably, the said connecting strips 169 are guided by studs 170 on the head 160 of the longitudinal slots 172 in the strips, and of course the outer ends of the strips must be as at 173, By this construction, the segmental shields can be all manipulated together by simply twisting or turning the disk 166 by hhnd. The segmental disk 166 also preferably has a slot 175 receiving a fixed stud 176 on the platen head,
' ment.
lVhen the cylinder is in position as shown in the drawings,
der as described feeds the stamps rearwardly downward, or in the direction shown by the arrow in Fig. 27, and as the row of stamps leaves the platen surface at 177, it passes between feed rollers 178,179. The inner one 178, of these rollers is mounted on a stud 174 projecting horizontally from the platen head 160and within said platen, while the rearward or outer feed roller 179 is fast upon a shaft 181 journaled at one end in a lower rear edge extension 182 of the end guard 87 of the cylinder, (see Fig. 33), and at its other end in an extension 183' of the (see Fig. 27) This platen platen entering to provide limits to its rotary moveand the end row of stamps. is lying on the platen, rotation of the cylinposition by a head extension 183 is slotted as at 200, in a direction away from the other roller 1T8v to form. the bearing for the shaft end, and said shaft end is normally pushed forward by a spring 188 'to hold the rollers in feeding engagement. with a row of stamps. This shaft is driven by a gear 184 meshing with the end gear 123 .of the cylinder (see Fig. To provide for separating said rollers to permit the insertion of a new sheetof stamps, or to bring a new row of stamps into position, and to do the same automatically, an arm 185 is provided upon a lower forward shaft 186 which arm reaches up and against the shaft 181 to push it backward against the power of the spring 188 (see Figs. 33 and 34-). The said shaft 186 carrying said arm 185 is journaled in posts 189, 189 on the bed plate, and at its end farthest from the belt 2 said shaft has a fixed arm 190 which overlies the shaft 7. A cam 191 upon the sleeve 151 on said shaft 7, adapted to engage said arm 190, then rocks the shaft 186 at suitable intervals to deflect the roller shaft 181 and disengage said roller 17 9.
As the sheet of stamps passes beyond the rollers 178, 179, it slides under a guide 192 attached to the platen head, the main portion of the sheet being on the cylinder, turning therewith and still connected to the row. At the end of this guideris a small roller 193 mounted in brackets 211 on the platen'160. This roller 193 is idle unless the original actuating shaft 85 is raised by the trip as has been described, when said. shaft presses" an intermediate roller. 195 mounted in a bracket 196, hinged as at 197 to the platen and forced downward by a spring 198, against the roller 193 on the opposite side of the stamps therefrom. Said rollers 193 and 195 then feed the stamps on downward to the moistening means, and atthe same time a circular knife 200 on the end of the upper roller 193 nearest the cylinder cuts the row of stamps loose and free from the sheet. The-moistening means comprise a small bath 201 which is somewhat triangular in end view, being arranged transversely of the belt 2 with its low edge forward, as shown in Fig.27. This bath 201 is supported at one end by a post 202 on the bed plate, and at its other end by the hanger strap 19 1 which reaches down into the bath and is apertured as at 203 to receive a lug 20s on the bottom of the bath (see detail Figs. 39, 40 and 41).
A moistening roller 205 is then journaled at one end in the top of said lug 204 and in the aperture 203 of the hanger strap, while the other end finds a bearing on the wall of the bath 201. Said roller 205 projects peripherally from the bath, as shown, and to rotate the same it carries in the bath a gear 207 I which meshes with a higher pinion 208 on a short shaft 209 extending through the hanger strap and having on its opposite end eenve a pinion.210 which receives motion through an intermediate pinion 213 from a pinion 212 on the shaft of the feed roller 193. The arrangement of pinions 208 and 210 on opposite sides of the hanger strap 194C prevents the transmission of water from the bath to prematurely moisten stamps farther back than the end one desired to be moistened for immediate application. In thus passin over the moistening roller 205, the forwar edge of the stamp engages the envelop and is caught by the roller 82before its rear edge has reached the moistening roller 205. Then as the feeding'rollers 193 and 195, cease feeding the row of stamps forward, a knife 215 mounted upon the rear edge of the bath, in
just right position, severs the end stamp from the row as it is still drawn forward by the roller 82 and belt 2, the next succeeding stamp being held tight between the feedrollers 178, 179. To secure a drawing out, the said knife edge is preferably slanted as shown in detail in Fig. 42.
For supplying the batl1 201 with water, a tube 216 leads thereto from the faucet 217 of a reservoir 218, and this faucet is autoshaft, as shown-in detail in Fig. 37, carries 9 a sleeve 219;;adapted to engage and slide longitudinally an adjacent sleeve member 220 on a longitudinally alined but separate shaft 105. v ably has a' reduced end 300 entering a recess in the end of the shaft 113, as shown in dotted lines, and at the other end of the said shaft portion 105, outside its bearing in the post 226, is a spring friction washer 230, which insures that the sleeve member 220 will be operated before said shaft portion begins to turn, it being understood that the beveled projections 301 on the sleeve 219 never entirely leave their correspondingly shaped recesses in the sleeve member 220. The second sleeve 220 has an annular groove 222 receiving the fork of a lever 223 fulcrumed as at 224 on a bracket 225 fast to one of the posts 226, 226, in which theshaft is journaled. The upper-end of said lever 223 is pivoted to the end of a horizontally disposed and longitudinally movable connecting rod 227, slotted as at 228 to receive a supporting pin on which it slides, and this rod in turn is secured by a slot and pin connection to the arm 229 of the said faucet 217 spring 303 normally holding said faucet Said shaft portion 105 prefer closed: A pin 304 projecting into a transverse slot of the sleeve 219, and a pin 305 projecting into a longitudinal slot of the sleeve member 220, serve to limit the movement of said parts and prevent their displacement.
In operation of the above parts, the pin 04 on theshaft 113, as the latter turns, en-
teams gages the forward end of its slot in the sleeve 219 and turns said sleeveg'this causes the beveled projections, 301 on the said.

member 220 has made its longitudinal movement, it remains in its new positionv and turns with the other sleeve member 219 be-..
cause the projections 301 do not entirely leave their recesses, and the spring 230 does not prevent turning when suflicient power is applied. lVhen the shaft 113 stops turning,
sleeve'member 219 which is in a row, by the means the spring 303 of the faucet closes the same, throwing the rod 207 and lever 223 back to their original positions, and thus sliding the sleeve member 220 back toward the member 219, which causes the beveled projections 301 to entirely enter the recesses, the transverse slot in the sleeve member 219 for the pin 304 permitting the slight reverse turning of said necessary for this purpose. 7
. The cylinder shown 119 is adapted to receive sheets ofstamps having ten in each circumferential row, and as before stated these rows do not reach entirely around the cylinder, but there is an'unoccupied space of two stamp widths. The cylinder is rotated enough to feed each successive stamp already described, a spring detent 231 enga ing spaced notches 270 onthe end of the cyl inder farthest from the belt 2 to accurately determine the points of stopping of said cylinder 119 between successive stamps. (-See Figs. 30 and 32). iVhen the last stampin a-row has been discharged or feed out, it'is necessary to turn the cylinder along in order to be ready to begin on the first end of the next row of stamps as another envelopcomes along. To automatically accomplish this, the means next described is eniployed. i
Upon the sleeve 151 of the constantly m.
tating shaft 7, and adjacent to the standard 8 farthest from the belt 2.21s shown in the 239 to receive'a drawings, is arranged a cam 232, (see Figs. 9 and 33), which-is adapted to engage the lower end of an upright lever 233 fulcrumed as at 234 and having its upper end slotted as at 235, to receive a pin 236 ofa hung loosely on the cylinder shaft 117. This 238 fast on the cylinder shaft, and having a notch,
