A in the drawing represents the'frame of,

2 our improved envelope-folding machine;` It is made of metal or other Suitable material, of

` suitable size and shape, suiiciently strong to sustain the machinerywhich is connected with the folding mechanism. B is the horizontal driving-shaft, hung in theframe Abelow the 4topplate or table a. ofthe same. From the face of the table a projects a vertical pin, b, to which is pivoted theblank-snpport C. This j blank-supportis aiplate of the requisite form, with a ange, c, at its front edge. It has a curvedslot, as shown in Fig. 2, so that it can e be swung fiush with a" curved rib, d, projecting f 7 is a plan or top view, partly in section, of the .2,.F`iM-3lRovEMENT` IN.

` trema., which 4rib enters said slot whenever e the blank-support is swung against the ixed stops e e, asin Fig. -7. The blank-support can be held elevated above the plate a by means of a' spring-catch, f, as shown in Fig. 3. In

. this elevated position of the blank-support an 4arm projecting fromthe latter fits against and under ahook, g, as shown in Figs. 3 and 4. -h is a Vertical pin projecting through the rib d,

. and fprovided with a spring whichthrows it up against the outer edges ,of the blanks on the support G, serving to keep them in place while the support is beinglowered, and swung back whenever it is to be adjusted for a new supply. A sleeveyt', sliding on one ofthe stops e, rests slightly on the upper blank, and acts as a weight for all the blanks, preventing all but the upper blank from adhering to the glimmer. The blanks are placed uponthe table A, under the elevated plate C, the pin h being pressed down. These blanks are placed against the stops e, whereby they are brought into the right position. The pin h is then released, and tends to hold the blanks in place. The rib d prevents the blanksfrom resting ush upon the plates a, and admits the plate C when the same has been swung out, as in Fig. 2, and lowered to be put under the pile of blanks. Thenceforth the blanks rest on the plate C, are held in place laterally by the stops e and ange c and by the pin h, and vheld down by the sleeve c'. From the pile on the plate O blanks are taken in proper succession by a gummed lifter, not shown. The lifter is gummed by a roller, j, which is hung ina vibrating frame, D. i This frame D swings on a pin, 7c, and is, by a system of levers, ZZ, connected with a cam, m, on the shaft B, whereby, and by a counteracting spring, n, it receives the necessary motion for applying the gum to the lifter. The blank,

which has been elevated and detached by the lifter, is taken from the same by a vibrating frame, E, which has hook-shaped arms, and

acts in the ordinary manner. The frame E is affixed to a sleeve or tube, o, which surrounds the pin la, and has an arm, p, at its lower end, which receives motion by a cam, r, of the shaft B. The frame E carries the blank from the lifter over the folding apparatus-that is to say, it moves from the position shown in Fig. 7 to that shown in Fig. 2. The blank is then forced down to the folders by a plunger, not shown, and has the several aps turned over by the several pivoted lingers s s of the folding mechanism, which operates in the well known or in suitable manner. Motion is imparted to the iin gers s by a cam or cams, t, on the shaft B. The envelope, after having been folded, is elevated from the folder by a vertically-slidin g yoke, F. The same rests upon a cam, fv, of the shaft B, and is elevated by the same after every envelope has been folded, and is then drawn down by a spring, i2. The two arms of the yoke hold the envelope elevated in such a position that it can be conveniently removed by a vibrating slide, G. This slide is a frame having downwardly-projecting fingers a2, and projects from the same tube o to which the frame E is affixed, so that consequently the movements of the frame E and G are simultaneous and in the saine direction. The frames E and G being thus connected, and their movements alike, it follows that a blank will be taken to the folders by E whenever the slide G removes anI envelope from the same. Considerable time and machinery are economized by this connection. The fingers a2 of the slide G push the envelope from the yoke upon two spring-arms, I I, which are affixed at b2, against the under side of an upright case or receiver, H. This receiver is a slotted case or receptacle for the envelopes. The springarms receive the envelopes, as stated, from the yoke, and the ngers a2 push the same along until they are just under the lower opening of the receiver. J is a vibrating comb pivoted to an arm or lever, L, which turns loose on the tube o, being affixed to a tube, c2, which surounds said tube 0. The tube c2 has a projecting arm, d2, which is actuated by a cam, e2, of the shaft B, whereby the arm L is swung in a horizontal direction. `It will be noticed that the pivots k, o, and c2 occupy the same axis, being arranged one within the oth er. This arrangement economizes considerable in the putting up of the machine, and prevents a great deal of unnecessary friction. An arm, f2, projecting from the under side of the comb J, straddles the head g2 of a T-shaped upright slide, M, whichis supported by a lever, h2, and receives motion by a cam, j, of the shaft B. Vhenever an envelope has been placed upon the spring-fingers under the receiver the comb J is, by the arm L, swung under such envelope, and is then swung up by the elevation of the slide M so as to lift the envelope from the said spring-arms. Thelatter are then free to receive another envelope by the slide G, and when that has arrived the comb is lowered and moved out of the way to let all the envelopes rest upon the spring-arms ceiver, clearing the arms for the reception of another envelope. The receiver carries a slide, k2, which rests as a yielding weight on the envelopes deposited under it.

There are or may be projections on the upper sides of the spring-arms I, just under the case H, to prevent the envelopes from being returned to the folders with the slide.

Having thus described our invention, we claim for us as new, and desire to secure by Letters Patent- 1. The blank-support G, pivoted to the pin b, and combined with the spring-catch f, hook g, and pin h, to operate substantially as herein shown and described.

2. The sleeve or weight t', arranged on pin e, as described, for the purpose of holding down the blanks and preventing more than one from being taken up by the gummer, as set forth.

3. The vibrating frameE combined with the slide G, and connected with the same, as described, so that one blank is conveyed to the folder whenever a folded envelope is being removed therefrom, as specified.

4. The pivots 7c, o, and 02 of the frames D E G and arm L, arranged around one axis, substantially as and for the purpose herein shown and described.

5. The vibrating frame G, having the ngers a2, combined with the spring-arms I, for conveying the envelopes to the same from the yoke F, as set forth.

6. The comb J, vibrating horizontally and vertically, and combined with the spring-arms I to lift the envelopes from said arms to clear them for the further reception of envelopes, as specified.

7. The vibrating frame L, combined with the pivoted comb J to actuate the same l1orizontally, .as herein shown and described.

8. The upright slide M, combined by the arm f2 with the pivoted comb J to actuate the same vertically, substantially as herein shown and described.
