TO ALL WHOM IT MAY CONCERN:

Be it known that I, Enos H. McAItTnuu, of Hillsdalc, county of Columbia," and State of New York, have invented a certain newand useful Machine for Cutting and Folding Paper; and I do hereby declare that the following is a full and exact description thereof.

- The object of my invention is to produce a machincwhich cuts paper from the endless .rolls, either singly or by the quire, and'to fold the same in the middle, which latter operation has been done hitherto, as I believe, by manual labor. My machine performs these operations muchmore perfectly and faster than can be done by hand. i v

Thenature' of my invention consists,- firstly, in means for feeding the, paper; secondly, in means for cutting the paper by a peculiar and novel draw-cutting motion; thirdly, in means fol-folding the paper, which is done by three distinct motions: first,'by placing a sharp or thin folding-plate on the top of the paper over which the samcis to be folded; second, the motion of the folding-table, folding the paper by its action over the edge of the thin folding-plate; third, in a motion to remove, by the action of the folding-plate, the paper which has been operated upon-from the table' fourth inmeansfor regulating the length of the paper which is to be out before it is acted upon by the folder.

. To enable others skilled in the art to make and use my invention, I will proceed-to describe the same by. the aid of the accompanying drawing:

Similar letters of referencee indicate like parts in the different figures.

Figure 1 is a side elevation, parts of the frame ofthe machine being removed to allow the working of the mechanism better to be seen. i

' Figure 2 is an end elevation, with parts of the end frame likewise removed, to show the working parts more clearly.

I will now proceed to describe thcimeans by which the different operations are performed in the order given above. I

First. The feeding apparatus consists of two rollers, B B, resting in bearings b b of the framing A of the maching. The roller B has mounted onthe end of its shaft a pinion, B to which is given an intermittent motion, necessary for feeding the paper-roller. B is the feed-roller proper, the roller B being only a counter-roller, producing the necessary friction to draw the paper through- The intermittent motion isprodu'ced by a gear segment, {3, mounted onthe shaft 0, and gearing into the pinion B of large roller B. The amount of feed is regulated by the length or number of teeth in this segment C, by whichthc amount of 'turn of rollerB is governed. Shaft c has on its other end a gear-whee], G ,'which is acted upon by a gear-wheel, D, on the main driving-shaft D of the machine, through an intermediate gear, 0 Thcmotiqn of the gear-whecl D, as well as that of the gear segment 0, is intermittent, and I will proceed to describe the means bywhich said intermittent motion is produced. Gear-wheel D is loose on the main shaft D; it is coupled to-the shaft by a clutch, d. This latter engages and disengages l) by the following mechanism: E is a small pinion, gearing into a gearwheel, E, secured by a stud to frame A. In front of this latter gear-wheel E, is placed al'horizontal slide-rod, E'fl'g ided in the bearings a a, and having-two studs e e, secured to it, which pass inward radially towards the centre of E, in the manner embracing the two sides of E like a fork. On the two opposite faces of E are circular cams e" e which act successively, substantially as shown in the drawing, on the two studs 6 and c, which are placed apart the breadth of the wheel and the amount of throw of one of the cams, and in this manner give to the bar or slide-rod, E, a to-and-fro motion. An arm, E reaches down from E and encircles the groove in clutch d- The clutch takes part in this manner of the to-and-fro motion of the'sliding-bar E and places in or out of gear a gear-wheel, D, which intermittent motion is transmitted to'the feed-roller B by the means above described.

When quires are tobe folded the feeding must take place as often as necessary to make up the quire to one of the folding motions, and the paper being drawn from four, five, or more endless rolls, it is necessary to take correspondingly many feeds and cuts to make up thequire before the action of folding takes place.

After each feed the cutting of the paper must be done, which constitutes the second operation. On the same shaft 0, on which is mounted the segmental gear-wheel C, is mounted on the opposite side another segmental ss,45o 2 gearewheel, F. The teeth of this latter are so arranged as to begin to act as soon as the feed motion is stopped, that is, as soon as the segment G stops to act on pinion B. This gear segment P acts on a pinion, F, on the shaftf. The pinion Fhas on its inner surface a stud,f, which gives an up-and-down motion to a cam frame, f and rodf This latter takes hold on one of the arms of an angle-lever, the arms of which I will callf and f and which turns on ccntref. It is readily understood that when arm f is moved upward by thestud f and cam frame f, the end of arm f will describe an arc of a circle from centre f, and is at the same time lowered. This latter arm is fastened to the knife G by a small bolt, '9. The knife is guided on the frame in bearings a a. This knife is well sharpened, and passes along the edge of a stationary knife-blade, G, secured to frame A of the machine. The other endof the knife G has a slanting slot, 9, surrounding a stationary pin, fixed to the guide-bearing of the knife, and the whole arranged in such a manner that when the knife is pulled towards the left, it wilhbe'movcd sidewise, and at the same time be depressed so as to pass by the edge of the stationary knife-blade G, and cut the paper or any other material interposed.

The motion produced by these mechanical means is the one best adapted for cutting, and is known under the name of draw shearing out.

After the paper is cut it falls on the folding-table ready to be folded, which constitutes the third or folding operation. The paper coming from the feed-rollers B B, is guided on top of the folding-table. The table is formed of two halves, H H, the latter being stationary, and the former movable and folding ov er H, by means of the hinge which connects the two halves at the point It. Before this movement takes place, the thin folding-plate L places itself on the top of the paper to be folded; it reaches fromth'ebaok of the stationary part H of the folding-table to the joint It, where the part H connects to H The paper is therefore held firmly at the pointwhere the fold is to be made.

The means by which the motion of this operation takes place are as follows The motion must be an intermitten t one, acting at' the time when the feed-rollers and the knife are at a stand-still: -The clutch don the main shaft is a double one,- engaging in a clutch on a bevel-wheel, J, loose on shaft D. p This is done by the same g'neans that the clutch engages and disengages the gear D of the feed motion. When D is disengaged, the teeth on the opposite end of the double clutch d engage in the teeth on bevel-gear J. By the motion of the latter the folding operation is performed. This motion of J is transmitted by bevel-gear J, shaft j, by bevel-gear J and J to a shaft, K.- From this shaft the folding part H of the folding-table is operated. On each end of shaft K is placed a pitman-Whcel, K K, with crimk-pins la Ir. On H are secured two lever-arms, h 71., formed, for the sake of stability, of the shape of an arc of a circle. The points-h h of these lever-arms are connected to the crank-pins k k", by the two rods K K. The amount of motion of crank-pins 7c and k is such as to turn the folding par't H, swinging on the point it to an angle of one hundred and eighty degrees, or from its original horizontal position to the horizontal position over the stationary part H, thereby folding the paper placed on the same. Before this action of H takes place, the thinfolding-plate L, over which the paper is folded, is placed on the paper. This is done by the following means: On shaft k, b'et\vecn the pitman-wheels,

is a pinion, I, geared into a wheel, M, of double the size, on a shaft, or. From here the motion is transmitted. by bevel-gears N O, shaft 0, bevel-gear O and to shaft 1;. On is a cam-wheel Q, the cam part q of which acts on a tappct, L, on awhcel, -L', on a shaft, Z, giving this latter a partial turn. On this shaft Z is secured the folding-plate L, which is operated by these means Wheel L has a groove worked out on its circumference; over it passes a cord, down to spring L; the action of this latter brings folding-plate L over the paper in the position shown intlie drawings. -When L is brought to an upright position by the means hereinbefore described,

it will carry along with it the paper folded over its edge, which can now be readily removed by hand. 'L

remains'for a certain time, necessary for feeding and cutting, in that position.

To fold paper of less width, (accepting the machine now to fold the largest everunccessary,) the frame part A, carrying the feeding-table, can be shortened by bringing the joint 72 of the folding part II nearer to the.

cutting-knife G, to the amount to which the breadth of the folded sheets is to be reduced, and moving in the gauge L, to the same distance against which the paper is fed. The food must be changed in the manner hereinbefore described. To allowthe shifting of the frame A, the latter is secured to A by four bolts, R R BF'R; the frame A is slotted, in which slot the bolts R pass. To make a change the bolts R 11, etc, are loosened, the frame A set,- tlic bolts R R, etc., tightened again, and the machine is ready to operate. The plate H, reaching up closcto the knife, must be shortened, for this purpose it is formed at the end of slats or narrow strips .of wood, secured to the main body of H by bolts. According to the change in width, more or less slats are taken from the table H.

The operation is now as follows: First, the feed takes place, bringing the paper on the folding-table up to gauge L. The feed being arrested, the cutting takes place. This being done, the motion is transferred to the folding apparatus, which has remained at rest during the first operation. The cam q releases the tappct L on shaft 1, and the folding-plate comes down on the top of the paper to be operated upon, and holds the same.

Now the folding part H isworked and the fold is produced over the edge of the folding-plate L. The part H now moves back to its original horizontal position. The cam part q now acts ag'ain'on tappet L, and L is brought .toa vertical or nearly vertical position, bringing along with it the paper folded. Here the motion to the folding mechanism is ended; the motion of the feeding and cutting mechanism begins anew. During this latter time the folded paper is removed from L, and so on.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent is as follows! I 1. I claim the application of a folding apparatus to a paper-cutting machine, substantially as and for the purposes herein set forth.

2. I claim the movable part H of a folding-table, in combination with the stationary part II of the same, and the folding-plate L, operating substantially as and for the purposes herein set forth.

3. I claim, in combination with a folding machine, thc folding-plate L, substantially as and for the purpose herein specified.

4. I claim, in a folding apparatus, the folding-plate L, in combination with tappet L, cam-wheel Q, spring L operating substantially as and for the purpose herein set forth. i

5. I claim, in paper-cutters, the knife G, in combination with angle-levers ff slot g, and pin, operating substantially and for the purpose herein set forth.

6. I.clain1 the provisions for adjusting the folding-table to the different widths of paper to be folded, substantially as aind for the purpose herein specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
