HAND PRINTING-WHEEL.

SPECIFICATION forming part of Letters Patent No. 232,856, dated October 5, 1880.

Application filed July 22, 1880.

To all whom it may concern Be it known that I, MICHAEL J. STARK, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements on Hand PrintingVheels 5 and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheets of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My present invention has general reference to hand printing-wheels, such as are used for markingboxes and packages, printing on packing or wrapping paper, paper bags, flour and other barrels, Sac., by means of a rubber impression-band secured to the periphery of a cylindrical roller, the impression-band being supplied with the necessary ink by inkingrollers caused to revolve in front of and in contact with the impression-band.

My invention consists in the peculiar and novel combination of parts and details of construction, as hereinafter more fully set forth and described, and pointed out in the claims.

In the drawings already referred to, which serve toillus'trate my said invention more fully, Figure lis a side elevation of my improved printing-wheels. Fig. 2 is a plan ofthe same. Fig. 3 is a sectional elevation in line y y of Fig. 2. Fig. 4 is a sectional plan in line :t xof Fig. 1.

Like parts are designated by corresponding letters of reference in all the figures.

Heretofore printingwheels have been made which consisted, essentially, of a U-shaped framehaving in the center of its cross-bar, or that part at right angles to the parallel inembers, a single backward-projecting handle, by means of which said printing-wheel was operated. Between these parallel members was journaled a cylinder carrying the impressiondie, and in front of this cylinder were two inking-rollers, one bearin g upon the other, which latter was also caused to bear upon the impression-die. In some of these wheels the cylinder was returned to its original position by means of aspring as soon as an impression was made, and the machine lifted from the surface upon which the printing was done, while in others the cylinder moved only in one (No model.)

is that, in order to supply all the wants of 6o the public, a large variety of sizes have to be made and constantly kept on hand. In putting up these printing-wheels they are required to be made in different lengths and diameters, and each diameter again with different lengths, so that wheels of, say, sixinches in diameter are required to be made anywhere from two to twelve inches in length. It will, therefore, be observed that to meet these requirements alarge number of U-shaped frames of all sizes have to be kept on hand, so as to supply from this stock any sized printing-machine that may be demanded by the trade.

In order to avoid this necessity of Ykeeping such a large stock on hand, and at the same time to enable me to furnish on short notice printing-wheels of a given diameter and any size in length, which is the object of my present invention, I construct my printing-wheel of a frame consisting of two separate sides, A A', connected together by means of a crossbar, B. Each of these sides has on its forward end two notches or slots, C, and, centrally, apertures for the passage of a pivoting bolt or rod, N. To the upper edge of these sides are cast handles F, running parallel with said sides, but standing outward, as shown in Fig. 2. On the face of the side A there are provided lugs G G, and through this side and in rear of said lugs there'is a slotted aperture, El.

Between the sides A A is journaled a cylinder, J, having on both ends plates K K', one of which has a slot-hole, j', for the reception of a lockingpin, a, on a catch, M, pivoted to the lugs GrV G on the side A by means of a pin, g, said locking-pin a being constructed to pass through the slot-hole H in said side A into the slot-hole f in said plate K.

On the under side of the catch-piece M is a small projection orrise, and inserted between the finger-piece m of said catch-piece M and the side A is a spiral spring, O, to keep the IOC catch-piece in a position to automatically lock the cylinder J as soon as the slot-hole fin the iange or plate K is in such position as to allow the pin a to enter.

The eylinderJ is journaled between the sides A A' by means of a rod, N, passing through said sides and the plates K K', one of said sides having a plain aperture for the passage of said rod N, and the other a screw-threaded aperture for the reception of the threaded portion of said rod N.

The cylinders J, when of small diameter,

are made of solid blocks of wood, a hole being bored centrally through them for the passage of the rod N; but when of larger diameter I prefer to form them in sections glued together, as shown in Fig. 3. By this construction I produce cylinders that are very light and at the same time not liable to shrink oval, the same as those made of a solid block.

In wheels having cylinders of considerable length it is diicult to insert a rod, N, through the entire length, owing to the fact that the aperture in the ilange opposite the side from which the rod is inserted cannot readily be found, so as to pass the said rod through the same. To avoid this trouble I make, for cylinders longer than six or seven inches, screwthreads in each ange K, and pass short bolts or pivots through the sides into the flanges, taking care to provide one pivot with a right and the other with a left handed thread and to form the threads in the plates K correspondingly, so that the pivots cannot unscrew when the machine is being used.

On the sides A A', I provide two hooks, l), to which I attach plates Q, having two apertures, into whichIhang springs S, one of which connects withthe upper ink-roller P, by means of a plate, B, hung onto the pivot p of said roller, and the other with the lower roller l?,

-themanner of attaching being clearly illustrated in Fig. l. These springs S draw the ink-rollers toward the cylinder J, so as to always revolve upon and with the impressiondie (not shown) secured to the periphery of said cylinder, and thereby to supply the same with the necessary ink.

The ink-rollers P should be covered with some good ink absorbing and retaining materialfelt being preferred-and with a layer of fine linen or cotton, to evenly distribute the ink upon the impression-die.

In the smaller-sized machines I make the screw-spindle N longer than necessary to pass through both sides A A', so that the projecting portion a serves as a guard for the spiral spring O.

On the connectin grod B, I form angular portions d, Fig. 4, fitting the angular apertures in the sides A A', to retain them in a parallel position, in conjunction with nuts I, engaging the screw-threaded portions e on said rod B.

It will now be readily observed that in order to supply at short notice printing-wheels of any length, I have only to keep on hand the neccessary wood for the cylinders and ink-rollers and castings for the sides A A' and the flanges or plates K K', so that it' I receive orders for wheels, say, six inches long or twelve inches long I have vnothing else to do but to cutthe cylinders and ink-rolls to the desired length and make rods B to tit the frames, when my machines are ready to ship, thereby saving me a large amount, which I would otherwise have to invest in frames, and considerable time in fitting up.

Owing to the fact that the handles F are formed integral with the sides A A', which are thereby produced entire in the process of casting, I can produce wheels of superior quality at a lower figure than those heretofore made. rlhese handles are so formed that their rear end is in line with the rear end of the sides A A', so that, assuming the line z z in Fig. 3 to be a base-line whereupon to rest the apparatus, the latter will stand in a vertical, or nearly vertical, position, whereby the inking-rolls and the impression-cylinder are sustained in the most advantageous position to prevent them from soiling surrounding objects with ink. This construction is quite an essential feature in my printing-wheels, and has largely contributed toward an extensive sale of the machines.

In operation the machine is placed, in the position shown in Fig. 1, upon the article upon whichaprintedimpressionis tobe producedand taken hold of by the two handles F. N 0W the nger-piece m of the catch Mis depressed to withdraw the pin a from the slot-hole f in the flange or plate K of the cylinder J and the machine moved along, which causes the impression-cylinder to revolve and pass over the surface to be printed. In the meantime the catch-piece lVI is released, so that as soon as the cylinder J has made a complete revolution the pin a will snap back into the slot-hole f, and thereby arrest further progress of said cylinder, the inking of the impression-die being performed by the ink-rollers P revolving in contact with said impression-die.

If desired, gages may be placed upon the rod B, to hang downward beyond the lowest point of the impression-cylinder, to guide the wheel over narrow boxes, and thereby to properly guide the machine.

Having thus fully described my invention, I claim as new and desire to secure to me by Letters Patent of the United States- 1. In hand printing-Wheels, substantially as described, sides A A', provided each with a handle, F, projectingfrom and above said sides, substantially as described, each of the sides being formed entire in the process oi' casting, as stated.

2. In hand printing-wheels, the combination, with the two sides A A', connected together at their rear ends by a rod, B, of the cylinder J and the spindle N, passed through said sides and centrally through said cylinder, said sides having angular apertures at said rear end, and said rod B having angular sections cl, fitting IOO IIO

said angular apertures in said sides, and nuts I, engaging the screw-Shanks e, whereby the parallelism of said sides is preserved, substantially in the manner as and for the object stated.

3. In hand printing-Wheels, sides A A', connected together in the rear by a removable cross-bar, B, and centrally by a bolt, N, having its screw-threaded end passed through and projecting from one of said sides, in combination with the stop M, having a pin, et, projection b, and spring O, said part of the rod N projecting from said side being constructed to serve as a guide for said spring O, as and for thc object specified.

4. In hand printing-Wheels, a frame having handles the rear ends of which are in, or nearly in, line with the rear ends ofthe frame, whereby the machine, when placed in, or nearly in, a vertical position is adapted to rest upon said handles and sides, substantially as described.

5. A hand printing-Wheel in which the sides of the frame are provided each With a handle projecting sidcwise and upward from said sides, and in which a stop for the cylinder is pivotcd to one of said sides, said stop having the thumb-piece m near the center of said cylinder, and the part carrying the pin a in rear of said thumb-piece m, whereby the pressure exerted upon the Wheel through the handles F is caused to act centrally upon said cylinder, and whereby, furthermore, the stop may be readily operated by one of the fingers of the hand holding the wheel, substantially as dcscribed.

6. A hand printing-Wheel composed, essentially, of two separate and removable sides, A A', each having a handle, F, projecting side- Wise and upward from said sides, a rod, B, connecting the sides at their rear ends, a cylinder, J, journaled between said sides upon a rod, N, or equivalent, and ink-rolls P, pivoted in slots in each side, one ot' said sides having a catch, M, substantially as described,` pivoted to said side in the manner as and for the object specited.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the presence of two subscribing Witnesses.
