JOHN H. LAW'LOR, OF BALTIMORE, MARYLAND.

PAPER-CUTTER AND DIE-PRESS.

SPECIFICATION forming part of Letters Patent No. 296,191, dated April 1, 1884.

Application filed January 15, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, J onn H. LAWLOR, of Baltimore, in the State of Maryland, have invented a new and useful Improvement in Paper-Cutters and Die-Presses; and I do hereby declare that the following is a full, clear, and exact description of thesame.

My invention relates to an improved machine for cutting piled paper, but which is also applicable, with slight mechanical changes, to all kinds of die-cutting.

The general plan of my machine includes, first, a sliding cross-head operated by a suitable gearing having a clutch mechanism, by

V which the movement of the cross-head is up to any desired line on the table, suitable clamping devices for holding the paper stationary, and a cutter head and knife operated by mechanism adapted to cause the knife to give a drawing out, the various devices and adjustments being under easy control of asingle operator, and capable of operation either by hand or power.

The invention consists in various improvements in construction and arrangement which make the operation and work of the press more effective, the parts more accessible for removal, change, and repair, and increase the efficiency of the whole machine.

The invention is fully illustrated in uumerous accompanying drawings, in which Figure 1 is a front elevation of the wholemachine; Fig. 2, an end elevation; Fig. 3, a section showing a portion of the machine in side elevation; Fig. 4, a plan view of the clutch; Fig. 5, a view of the table and scale; Fig. 6, aside view of the follower and its actuating mechanism; Fig. 7, a plan view of the same; Fig. 8, aseparate view of the cutter-head; Fig. 9, a top view of the cutter-head and adjacent mechanism; Fig. 10, a view showing a die substituted for the paper-cutter.

In these drawings, A represents the frame of the machine, composed of two upright standards or side pieces suitably braced and adapted to be screwed or bolted to the floor or otherwise rigidly set up;

B is the main drivingshaft of the machine, which runs in bearings 1 1, secured to the frame at the front of the machine, and has at one end a fly-wheel and crank-handle, and at the other tight and loose pulleys, adapting the machine to be run either by hand or power.

is the cross-head, which. has a vertical movement in slots 2 2 in the side standards of the frame above the table D. The table is secured rigidly to the frame at a point just below the bottom of the slots 2 2, so that the cross-head in its movement approaches nearly in contact with the table. A reciprocating motion is communicated to the cross-head in the following manner: A pinion, 3, is keyed upon the driving-shaft B, which meshes with a large pinion, 4, mounted loosely on theshaft E. Upon each end of the shaft E is a faceplate, F, with wrist-pins, to which are attached the pitmen or connecting-rods, G, the other end of which is pivoted to the crosshead. Connected to the pinion dis a small pinion,5,which meshes with a pinion, 6, keyed upon a shaft, H, journaled in the main frame in the back part of the machine. The shaft H may therefore receive a rotary motion in the same direction as the drivingshaft, while the shaft E remains stationary.

In order to communicate motion to the shaft E, the face-plates, and thence to the crosshead, I mount loosely upon the shaft H a pinion, 7, and clutch 8. Splined upon the shaft H is a sliding clutch, 9, which revolves with the shaft, but is moved longitudinally thereon by means of lever 11, the latter being pivoted upon a standard on the loose sleeve 12 on the shaft E. The pinion 7 meshes with a spur-wheel, 13, on the shaft E, and when the clutch mechanism is in engagement the shaft E is caused to rotate, and thereby give vertical movement to the pitmen. and cross-head. The lever 11 extends out to the front of the machine within convenient reach of the operator. It will be understood from the description heretofore given that by my arrangement of the shafts and their conneetinggears I obtain a large increase of power without in convenience in respect to the shafts and driving-wheel and pulleys. This gives but one set of gearing, and consequently less power. Another advantage resulting from the de scribed arrangement of shafts and pulleys is,

the shaft are in convenient position for belt connection with a shaft either overhead or below, and a fiy-wheel may be placed upon the other end of the shaft, with a handle for handpower which is within convenient reach of the operator. Another advantage arising from the construction and arrangement of the parts is, that the gears are all brought within the frame and are out of the way of the operator; and, further, there is ample room for the fast and loose pulleys upon one end of the main shaft, and a flywheel upon the other, without interference with the position of the pitmen or connecting-rods.

The pitman or connecting-rod G, Fig. 2, is composed of a lower portion, 14, connected by a wrist-pin to the face-plate F, and an upper portion, 15, which is pivoted on the projecting pin of the cross-head, and is provided with a wide slot, 16, hereinafter referred to. The parts 14 15 are connected to each other by a .rod, 17, having right-and-left-hand screwthreaded ends, which engage with correspondingly-threaded holes tapped in the parts 14 15, and a square or angular portion, 18, to receive a wrench or spanner for adjusting the cross head and edge of the knife or other cutter to the surface of the table.

The cutter-head or stock is shown at I, more particularly in Fig. 3. The cross-head is slotted, as at 19, and the cutter-head is held in position immediately below such slot by screwbolts 20, which pass through the slot into holes tapped in the top of the cutter-head, and are provided with milled heads 21, and the lower side of the cross-head has a broad base, forming flanges 22 22. The cutter is shown at 23, Fig. 3, and may be attached to the cutter-head by screws.

The mechanism so far described accom plishes the vertical movement of the crosshead and cutter. It is necessary, however, to give a longitudinal movement to the cutter independently of the cross-head to form the draw out.

Referring more particularly to Figs. 1 and 8,it will be seen that the cutter-head I is provided at one end with an inclined extensiomin which is a slot, 24. The other end is made plain, and both ends project beyond the framework through the main slot therein, in which the cross-head slides, such ends coming directly opposite the slot in the upper end, 15, of the connecting-rods, before referred to. Within the inclined. slot 24 is placed a tubular roller, 25, mounted loosely on a rod, 26, which passes through cars 27 on the main frame. It is evident, therefore, that the vertical movement of the cross-head will cause a similar movement of the cutter-head, and that the latter will receive an independent sliding movement across the table by reason of its inclined slot bearing upon the roller on the rigid pin. The screws 20, which connect the cutter-head to the cross-head, pass through small rollertrucks 28, which run on top of the cross-head,

the screws moving in the slot 19. Rollers 29 are also journaled loosely in the cutter-head, which bear upon the flanges 22 of the crosshead. The screws 20 and trucks 28 are connected by a bar, 61, through which the screws pass, and which gives uniformity and steadiness to their motion.

In devices of this class the removal of the cutter-head and knife has usually been effected by disconnecting the connecting-rods from the crosshead and removing the latter. In my device, by simplyloosening the thumbscrews 20 and driving out the pin 26 the out ter-head and cutter may be withdrawn through the end slot and the openinglG in the connecting-bar, and without removing the connectingrod. and it maybe replaced with equal case.

J represents the paper-clamp. (Shown in Figs. 1 and 3.) It may be made in one piece; but, as shown in the drawings, it is composed of two parts, 30 31. The part 30 is the clamp proper, which is in cross-section in the form of an angle-iron or rabbeted, and in the rabbet lies the bar 31, the ends of which extend through the slots in the side pieces of the main frame, and are connected to the ends of the yoke K by connecting-rods 33. The construc tion of the clamp in two parts is sometimes convenient where small dies are used upon the cross-head, as the main part 30 may be removed from the cross-bar 31 without disconnecting the cross-bar from the rods.

In order to raise and lower the yoke K,and' thereby lift or depress the paper-clamp, I have provided a screw, 80, the upper end of which has its bearing in the boss on the under side of the table. ternally-threaded boss near the center of the yoke K, so that when the screw is turned one way the yoke is depressed and the paper-clamp brought down, and reverse movement raises the paper-clamp. In order to turn the screw conveniently, and with proper force to apply the desired pressure to the clamp, I fix upon the screw a horizontal wheel, 36, which may be either a crown or a bevel-gear wheel. Into this wheel meshes a corresponding pinion, 37,

keyed upon acounter-shaft, 38, which is journaled in a bracket fixed to the under side of the table, the end of the shaft projecting to the front, and being provided with a handwheel conveniently in reach of the operator. This construction and arrangement of the parts renders it practicable to apply any desired power to the paper-clamp, and the operator may bring down the paper-clamp without moving hisposition in front of the machine.

L represents the follower or gage for pushing the piled paper to proper position beneath the clamp and cutter. Referring to Fig. 5, the table has a long slot, 40, in which works the standard 41, to which the gage L is pivoted. The standard is formed with athreaded lower end, 42, which engages with a screw-rod, 43, with a collar journaled in the frame so as to turn, but not moved lengthwise. The rod 43 The screw passes through an inhas at its front end, Fig. 6, a bevel-pinion, 44, which engages with a pinion, 45, on a shaft, 4.6, journaled in hangers 47 on the under side of the table. On the right-hand end of this shaft is a crank within easy reach of the operator as he stands in front of the table. Obviously the turning of the shaft 47 will impart a rotary motion to the screw,which will consequently give a sliding movement to the follower. The special advantages of this construction are first, that, by means of the transverse shaft and crank, I am enabled to have the operating devices, both for shifting the gage and for bringing down and raising the paperclanip at the front of the machine,where they may be worked by the operator without stirring from his proper position; and, further, this arrangement also gives room for a large wheel, crown, or bevel upon the shaft which operates the screw moving the gage to the front or rear;

and as this wheel is much larger than the pinion upon the front end of the screw, it imparts a rapid motion to the screw, and thus moves the gage more rapidly than it could be moved it the hand wheel or crank were attached directly to the front end of the screw.

The proper adjustment of the follower is readily determined by a scale, 48, on the edge of' the table and an index-finger on the end of the gage. In the construction shown, the index-finger being pointed at the end, will indicate exactly the position of the gage even if thepaper covers the whole width of the table and that part of the scale which is in front of the pointer.

In order to bring the paper to the cutter'in proper shape to be out diagonally, I have shown the plate or gage L as pivoted to the standard, and adjustably held in place by a clamping-screw, 49, and guide-block 50, Fig. 6. The latter is secured to the gage on its lower side, and slides with. it in the slot 40 of the table. If the block, however, be removed, (by loosening screw 51 and the set-screw 49,) the plate can be swung on its pivot to the required angle. The screw 49 passes through a curved. guide-slot, 52, in the plate L.

The construction heretofore described of v the slotted crosshead and of the knife-bar,

and the devices whereby the knife-bar is attached to the crosshead, serves another very importantpurpose. In machines of this class as heretofore made only a knife could be used upon the machine. If the owner of the ma chine desired to work with dies, or with any kind of a tool other than the ordinary knife, he must provide himself with another machine, thus doubling the expense; but with the construction shown and heretofore de scribed, after the ordinary knife is removed, as has been explained, any kind of a knife or die may be substituted in its place in the same cross headas, for example, aknife may be inserted for scalloping the edges of paper, or for cutting any irregular form or pattern; or round or fanciful dies may be used, either one cross-head.

or more, in the same cross-head, for cutting labels or any ornamental pieces out of paper. As an example of a device which I may thus substitute for the ordinary knife, 1 have shown in Fig. 10 a die, M, which may be substituted for the "cutter-head and cutter. The latter are removed in the manner before described, and the die M connected by the screws 20 20, which in this case pass through a short block, N, which serves only as a washer, and

which in large machines may be omitted.-

The screws 20 are screwed into holes tapped into or through ears on each side of the die or the ring which holds it. Instead of this con struction I may use hooks formed on the lower end of the screws, which hooks may take into holes in a plain wall of a die, the threads be ing upon the upper ends of the screws, which are in this case drawn up by nuts on top of the cross-head. Any other convenient means may be used for connecting the die to the It will be apparentthat when the knife and knife-bar are removed the connections are also removed by which endwise movement is given to the cutting-instru ment, the main crosshead itself in all cases moving vertically. It therefore follows that when the dies are attached to the cross-head these dies have only vertical movement, which is the only movement required for such instruments.

The upper part of the frame is connected by a crossbar, 60, which in this case is a small rod, and serves only the purpose of steadying the side pieces. Preferably this cross-bar is made high enough so that the screws may be raised clear from the cross head. It will be observed in connection with this that the devices which operate the paper-clamp are .all underneath the table, and the clamp is drawn down from below; whereas ordinarily the clamp is pressed by a screw having its bearings in the frame above it. This is an important feature in connection with the removable knife heretofore described, as a screw set in the frame above would interfere with the removing of the knife and the interchange of dies and cutters heretofore referred to.

Having thus described my invention, what I claim is- 1. In a papercut-ting machine, the combination of a cross'head adapted to slide vertically in the frame without lateral movement, and a removable cutter connected to said cross-head, and adapted to reciprocate later ally by the vertical movement of the crosshead, substantially as described.

2. In a paper-cutting or die press, a vertically-reciprocating and slotted cross-head, in combination with interchangeable cutters and dies.

3. The combination, with the sliding crosshead and its connecting-rods, having the tie scribed opening, of the removable cutter-head and cutter.

4. The slotted cross-head, in combination ICC with the open connecting-rods, the cutterhead and cutter, and the screws 20.

5. The combination of the sliding cross head having the slot 19, the cutter-head, having the inclined slot, the pin 26, the screws 20, and the rollei trucks.

6. Combined with the pivoted sliding follower, the removable guide-block 50, substan tially as described.

7. In combination with the framework of the machine, substantially as described, the main driving-shaft provided withfast and loose pulleys and flyiwheel, the pinion fixed upon said shaft, the central shaft connected by wrist-pins to the connecting-rods of the'15 cross=head, the loose-gear wheel 4 and pinion 5 on said central shaft, the rear shaft and its fixed-gear wheel 6, meshing into theloose gear, and the clutch mechanism and loose pinion on the rear shaft, and a fixed gear wheel, 13, on 20 the central shaft.

In-testimony whereof I have signed my name to this specification in the-presence of two subscribing witnesses.
