Serial No. 646,951.

To all whom it may concern:

Be it known that I, GEORGE T. TRUNDLE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Stamp-Allixers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a very simple and effective mechanism for aflixing stamps to envelops.

My machine is designed to operate with great rapidity on envelops of various sizes, having inclosures of various thicknesses. It is designed to carry a roll of stamps and automatically affix them as the envelops are fed, controlling the feed of the stamps by their perforations, so that inequalities in the length of individual stamps will not be troublesome.

The invention consists of the means by which I carry out the above mentioned operations, or any of them, as hereinafter more fully explained and as definitely set out in the claims.

In the drawings, Figure 1 is a side elevation of the envelop and stamp feeding portions of my machine, this figure illustrating the principle of operation; Fig. 2 is a side elevation of a complete machine, embodying such principle; Fig. 3 is a plan of such machine; Fig. 4 is a detail of a portion of one of the envelop feeding rollers, being horizontally sectioned through the ournal thereof.

As shown in the drawings, 10 and 11 represent one pair of feeding rollers and 12 and 13 another pair adapted to propel through the machine the envelop to be stamped. This envelop with its inclosures is designated 15. The rolls 10 and 12 are shown as mounted on stationary axes, while rolls 11 and 13 are spring pressed toward rolls 10 and 12 by springs designated 17 and 18, acting on the journal boxes of the rollers. The roll 11 is constantly pressed by its springs 17 into a position to cooperate with roll 10, while roll 13, though constantly under spring pressure, is adapted to be held out of action, by means hereinafter described. The four rolls mentioned are continuously revolved in a di- The means 7 shown in Figs. 2 and 3 for causing such revolution consist of a sprocket chain 23, engaging sprocket wheels 21, 22, 23 and 24: on the rolls and intermediately engaging the driving sprocket wheel 25 on a driving shaft 26. It is to be understood that any other means may be employed for rotating the rolls mentioned.

The stamps are adapted to be furnished in a continuous roll thereof, designated 30,

which occupies a cylindrical case 31. The stamps pass downwardly through an opening 32, in the case, between a pair of feeding rolls and 3 1. These rolls grip the stamps between them, the rolls being intermittently revolved to feed the stamps. As shown, the means for causing the intermittent rotation consists of a reciprocating rack 40, the teeth of which mesh with a pinion 11, which is loose on the shaft of the roll 34 but cooperates with a pawl, 12, carried on that roll. Accordingly, movement of the rack in one direction rotates the roll 34, and hence the roll 33, while movement in the opposite direction is idle, the pinion 41 clicking under the pawl, and friction (or a detent not shown) holding the rolls against backward rotation. The rack 40 may be conveniently reciprocated by having its end connected with a crank arm 44, on a continuously r0 tating shaft 15.

50 indicates a series of parallel fingers pivoted on a shaft 51, and adapted to rest on the surface of the stamps 30, being fed from the roll of stamps. The points of these fingers stand between guards 53 and 54 above the stamps and over a depression in a guard below the stamps. The fingers descend by gravity and are adapted to be raised by a yoke 57, pivoted on the shaft 51 and having a transverse bar 58 standing beneath the fingers. On the shaft 51 is an arm 59 which cooperates with a cam 60 on a continuously revolving shaft 61. This cam is accordingly adapted to raise the fingers together from the stamps, while, when the cam allows the arm 59 to descend, the fingers may rest lightly by gravity on top of the stamps and are adapted to fall through the perforations thereof into the recess in the guard and thereby prevent the advancement of a stamp behind the fingers and enable the rolls 12 and 13 to pull ofi' the stamp in advance of the fingers. The cam shaft 61 and the shaft 15 may conveniently be revolved by a sprocket chain 63 engaging sprocket wheels on these shafts and a sprocket wheel on the shaft of the rotating roller 11. The cam shaft 61 is shown as carrying a pair of cams 71 which act on the levers 70, the other ends of which bear down on the journal boxes of the roller 13. The cams 60 and 71 are so related that as the cam 60 releases the fingers 50 to stop the stamps the cam 71 releases the levers to free the roller 13, which thereupon rises into gripping engagement with the envelop and stamp.

It is to be understood that the envelop is moistened adjacent to the corner before the stamp is applied to it. No means is shown in the drawing for accomplishing this as any suitable mechanism may be employed, as, for example, that shown in Patent #971,940, October 1, 1910 to Clarence E. Van Duzer. Whatever moistening device is employed preferably acts on the envelop after it has passed the rollers 10 and 11.

In the operation of my stamp affixer, the envelops are fed, one after another, by hand or suitable mechanism, between the rollers 10 and 11. In this feeding the envelop stands with the flap edge foremost and the flap on the under side. After the top portion of the envelop has passed the rollers 10 and 11, it rides along on the plate 19, and the corner is suitably moistened. Then, as the envelop comes bet-ween the rollers 12 and 13 the stamp has been fed down from the stamp case ahead of it and comes onto the top of the envelop adjacent to the roller 12. As this takes place the fingers 50 (which have been lowered onto the stamp by being re leased by the cam 60) rest on the forward stamp in advance of theperforations, indicated at 35 in Fig. 1. Then, the cams 71 release the levers 70 so that the roller 13 rises into gripping engagement with the envelop. The envelop and stamp are now gripped between the roller 12 (which is rubber) and the roller 13, and the stamp is pulled off from the next stamp, which is stopped by the fingers 50 dropping into the perforations at the rear of the stamp. Thus, the stamp is firmly affixed to the envelop by the roller 12, and the stamped envelop is fed out of the machine.

Having thus described my invention, what I claim is 1. In a stamp afiixing mechanism, the combination of a holder for a row of stamps and means for propelling the envelop, of a stopping device for the stamps adapted to enter perforations between successive stamps, and rollers adapted to pinch between them a moving envelop and a stamp next in advance of the engaged perforations, and serving to pull the forward stamp off of the stopped row of stamps and press such forward stamp against the envelop.
