` PAPER-FOLDING MACHINE.

.EPECFICATION forming part of Letters Patent No 335,096. dated January 26, 1886.

Application filed March 14, 1883. Serial No. 88,068.

To a/ZZ whom it may concern Be it known that I, JOHN H. STONEMETZ, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented certain new and useful Improvements in Paper-Folding Machines; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

fIhis invention relates to paper-folding machines; and it consists in the construction and combination of parts, as hereinafter fully set forth in the claims.

The objects of this invention are to improve the construction and operation of the feeding devices and the pasting mechanism.

In the accompanying drawings only such parts of the folding-machine are shown as are necessary to properly illustrate theinvention, the illustrations being as follows:

Figure l is a top or plan view of the feedroller and pasting devices, which are located at the front part of the machine. Fig. 2 is a vertical transverse section ou the line .t x in Fig. 1, looking in the direction of the arrow on said line, the feederolls F being omitted in this figure. Fig. 3 is a side elevation looking in the direction of the arrow at the lower side of Fig. 1. Fig. 4 is a similar view to Fig. 2, enlarged, and having the pasting mechanism partly broken away,the parts being in a different position. Fig. 5 is a side view of the upright J, and shows the elongated bearing j of the shaft E, the collar E', and the cam 13.

The parts are indicated by letters as follows:

A is the feeding-table on the topof the folder.

B B are the driving-belt pulleys, mounted on the shaft B2.

C C are the first folding-rollers.

S is the first tucking-blade.

E is the shaft which carries the feeding-rollers and the paste-knife.

D is a cogged gearon the shaft E, for driving the same, which gears with the cogged gear on the end ofthe roller C.

F F are the feed-rollers, which are narrow- (No model.)

faced wheels with one-sixth of their periphery depressed, as at F, making them sectors of live` siXths ofa circle.

f is a rubber tire or face on the feed-rollers F.

G is a sector-shaped paste-knife mounted on the arm G, extending from the shaft E.

His the pastecup.

h is a roller working in the paste cup and in frictional contact with the paste-knife G.

hand h2 are pulleys for driving the roller 7ly from the shaft E.

I I are cogged gears at each end of the shaft E, which gear with cogged gears II/,mounted on studs Il on the standards J.

I3 are cams,which are rotated by the cogged gears I I.

E are collars on the shaft E, which tread upon the cams 13.

j j are slotted bearings for the shaft E in the standards J J, to allow the shaft to rise and fall as the collars E roll upon the cams I.

K is a sector-shaped arm Xed to the shaft E, andprovided with a curved slot, Z.

L is a clamping-screw for clamping the arm K upon the gear -wheel D,which is loose upon the shaft E, and is thereby brought into connection Awith said shaft. k is an index ou said arm K, and 7c is a graduated scale on said gear D.

M is a second cam on one of the cams l, which, through the lever m and roek-shaftM, operates the feed gage m. A series of disks, p, are provided, and are secured on a shaft journaled in the frame ofthe machine, so that the paper which passes between the rollers F and C may be guided between the rollers C and C and the folding-blade.

From the foregoing and from the drawings it will be observed that the paste-knife and the feeding-rollers are mounted on one shaft, E. The feed-rollers F are xed upon this shaft. The paste-knife arm is adjustable upon it by a set-screw, g2, and thus the relative position of this knife to the peripheries of the feedrollers F can be regulated to suit the size of the paper being folded. The gear D, which drives the shaft E, is timed in its movements by the rollers C C', but it is loose on the shaft E, and connects therewith ZOO incontact with the roller h.

yfastened to the shaft, and hence the cams I3 always occupy the same position relatively to them, and the size of these gears is such that the shaft makes two revolutions to the cams onefhence the cams will act upon the shaftat alternate revolutions. The cams act upon the Ashaft through the collars E', and their action is such as to raise the shaft up in its slotted bearingsj. The time of action is when the .depressions F in the feed-rollers F are down neXt to the roller C. The cams I3 are of such a form as to hold the shaft up half of the time, so it will be seen that the feed-rollers F are in contact with the roller C during one revolution and not during the next revolution. As the adjustable arm K, byI its adjustment upon the gear D, Xes the relative position of the parts upon the shaft E tothe drive-gear D, and as the cams I3 get their movement from the shaft E, the relative time of the drop of the feed-rollers upon the paper is gaged bythe position of the arm K with relation to the gear D, and this may be varied to suit the size of the sheets of paper.

In Fig. 3 the feedrollers are shown down, and in Fig. 4 they areshown up. As the feeding-gage m receives its motion from the cam M, which is on one of the cams I3, it will be timed in its movement to correspond with the vertical movement of the feed-rollers. The paste-knife G' comes into contact with the paper in the same manner as the feed-rollers', being fitted upon the shaft E; but its action upon the paper may not commence until after the feed-rollers, for it may be so set that in its revolution it will not reach the paper until after it (the paper) has been started by the feedrollers. rIhis adjustment is regulated by the adjustment of the arm G on the shaft. Paste is deposited upon the knife Whenit comes j The belt which drives the roller h should be elastic, as the shaft E moves up and down, as described.

The index k and scale 7c will' What I claim as new is I1. IIn a .paperffolding machine, the combination, upon .one shaft, of sector-shaped feedingrollers, a paste knife, a driving gear, and means, substantially as shown, for securing said shaft to said drive-gear at various points, whereby the parts upon said shaft may be timed to move at varying relation to the other parts of said folding-machine, substantially as set forth.

2. In a paper-folding machine, the combination, substantially as shown, of the following elements: thevertically-movable shaft E, the driving-gear D, gearing with the roller C', the arc-shaped arm K, with slot Z and clampingscrew L, the sector-shaped feeding-rollers F F, the collars E E', the gears I I I I', and, finally, the cams I3 I3.

3. In apaper-folding machine, the combination, substantially as shown, of the followin driving-gear D, gearing with the roller C' and adjustably connected upon the said shaft E, the sector-shaped feeding-rollers F F, the adjustable arm G, with paste-knife G,and, finally, means, substantiallyl as shown, for moving said shaft vertically, in the manner and for the purposes set forth.

4. In a paper-folding machine, the combination, substantially as shown, of the following elements: the vertically-movable shaft E, the driving-gear D, gearing with the folding mechanism of said machine and adj ustably mounted on said shaft, so as to permit the parts on said shaft and operated therefrom to be variously timed in relation to the movements of the said folding mechanism, sector-shaped feeding-rollers F F, substantially as shown, mounted on said shaft, and, nally, means, substantially as shown, operated from said shaft, for lifting and holding it up during alternate revolutions, for the purposes mentioned.

5. In a paper-folding machine, the combination, with the drop-roller shaft E, of the pinions I I I I', the cams I3 I, and collars E E, substantially as shown.

In testimony' whereof I affix my signature in presence of two Witnesses.
