`IMPROVEMENT IN PAPERfFOLDING MACHINES.

The Schedule referred tb in these Letters iatent and making part of the same.

lb all whom it may concern:

Beit known that I, JOHNIMGADAMS, of Brook- Y lyn, in the conntylof Kingsland State of New York,

`have invented ccrtainr-new and useful Improvements .in Machinesior `Folding Paper and other Material`s,

applicable to fthe folding lof ballots and to other pui-poses; and do hereby declare that the following `and` other materials for various-purposes, is mainly designed for and `will here be described exclusively with reference to the automatic folding of ballots,

whereby time and'` labor are economized, and a close and accurate folding of said articles is produced and l' the saine delivered in packages or .piles ready for use.

The invention consists in acombiuation of feedingrollcrs with a stationary doubler or folding-trough or troughs, according to the number of folds required;

Also, incornbinaton with one or more ldo'ublers or b .i'oidcrs, of a presser, composed of endless belts, through which the'doublcd ballot or article is-passed or drawn. Likewise, in a receiver' or packing-receptacle provided-with a yielding follower4 and a. belt-conductor, between which andthe follower the folded articles as they come from the presser are fed in succession till a pile of the requisite sizeor thickness is obtained between said belt and follower.

l l Referring tothe accompanying drawing- A represents a feed-board or table, down or along which the unfolded ballots arefed one at a time, or

in advance of` cach other, to andl between upper and lower feeding-rollers, B B 'and C O', and between India-rubber or other suitable feeding-belts, D D', made `to connect, respectively, said upper and lower feeding-rollers, the one or upper pair, B B', of which are arrangcdwitllin a doubling-trough, or, as' it may be termed, doubler or folder E,' while the other or lower pair C C', work through a slot, l), in the bottom of thedoubler or folder, and which is covered by the belts D D. l These belts serve to guide and feed in a soit but positive manner, free from anyy liability to tear, each ballot .or blank in succession, and to1 pass it through the doubler or folder E, which is of a boatlike form to effect `a longitudinal foldor doubling` of the `ballot as it is drawn or propelled by the feeding devices through `the open front end c of the doubler.

Another doubler or folder\vith feeding-rollers or devices, may be arranged in front of the' doubler E to receive the ballot as it issues from the first doubler, and so on for any number of donblers witlrfeeding devices in succession, the one in advance oi the other, and each succeeding one turned to occupy right-angled positions to its preceding one, in the saine gen* eral line'or travel of the feed, forthe purpose of forining 4a succession of doubles in the ballot; but a single doubler, E, will sufticeto explain .the action ofY thev machine, it only being necessary to arrange the subsequent folding and packing devices, as hereinafter described, with reference tothe position of the last doubler, which, so far as said devices are concerned, thedoubler E maybe supposed to be.

From said doubler E the doubled ballot is passed' vby the feeding devices to and between a presser, composed of belts F F', lying face to face and passing 'around pulleys d d, the same traveling as indicated by,"` their respective arrows, and the doubled ballot passing in between ,and through said belts, that serve to gently but' positivelyform the fold in the ballot in the line of its double.

Motion is communicated to said 'presser by pulleys and belt, e, from a main drivingshaft, G, and by a cross-belt, f. Y

rlhe feeding devices in or connected with lthe doubler or folder` E, vare also suitably driven by belts g g and pulleys from or by the saine main shaft.

, From the pressing-belts F -h",- that likewise operate to continue the feed or travel ofthe iblded ballots, each ballot in succession is'caused, asit issues from the presser, toenterin between an endless travelingbelt, kl, (driven tomove as indicated by arrow in the drawing,)-auda yielding follower, l, of a receiving or packing-receptacle, J, the folded ballots being piled in succession'the one upon the other from, as itwere, the bottom of the receiver and the follower I, which is kept up to its Work by a spring, h, heilig forced backward as the folded and pressed ballots are entered in succcssion'between the pile and the belt H, that serves not only as a soft bed for the ballots as forced outward by the follower, obviatiug all liability totear, and admitting ofthe 'easy introduction of the ballots, but that servesV also to feed or draw the ballots into the packing-receptacle or receiver J.

'lo insure the proper entrance of the folded ballots Within the receiver, the pulleys i, j, and k, around which the belt H is made to travel, are so arranged relatively to the presser that each ballot as. it issues from the latter strikes ou an angular rim or in a gliding manner on said belt,so that it is prevented from striking on end the preceding ballot, and is caused to be Safely deposited on the top or outer surface thereof.

The ballots as packed or piled are drawn ont trom the receivervJ at intervals without, of necessity, stopfeeding devices arranged as described and in front of ping the operation of the machine. said presser, essentially as described.

What is here claimed, and desired t0 be secured by 3. 4The combination and arrangement of the belt H Letters Patent, isand its pulleys i j k with the follower I of the packing- 1. The doubler or folder E, in combination with receptacle or receiver J, essentially as shown zmd defeeding-rollers and belt, arranged to work through the scribed. bottom of said folder, substantially as specified. Witnesses: JOHN MCADAMS.

2. The presser, composed of endless traveling-belts FRED. HAYNES, F F', in combination with a doubler or folder, and the R. E. RABEAU.
