PRINTING IMPLEMENT.

Application filed April 5, 1916.

Be it known that we, GRAHAM E. BLACK and JAMES Wnrr WHEELER, citizens of the United States of America, and residents of Huntington, county of Cabell, and State of IVest Virginia, have invented certain new and useful Improvements in Printing Implements, of which the following is a full and clear specification.

The object of this invention is to provide a simple hand implement for stamping and canceling purposes, and the invention conssts of certain novel features of construction hereinafter described and claimed.

In the drawings- Figure l is a perspective view;

Fig. 2 is a horizontal sectional view;

Fig. 3 is a longitudinal sectional view with the two rollers and their bearings and actuating springs removed from the handle memj ber; and

Fig. 4 is a transverse sectional view on the line 1 -4 of Fig. 3.

Referring to the drawings annexed by reference characters, a designates a handle which is shaped for conveniently grasping it at the rear end and is provided with our improved devices at its forward end. Fastened to each edge of the handle at its forward end is a channel iron b, open at its forward end and having its open side facing inwardly. These channel irons are fastened to the handle by suitable screws c, the edges of the handle being shaped to t into the channels of the irons. Slidably mounted in the channels are two pairs of bearing blocks d and e. The inner or rear pair of blocks Z supports the hollow journals of the hollow inking roller f, and the other pair of blocks e rotatably supports the journals of the stamping and canceling roller g. The blocks e and d at each side are normally pressed away from each other by means of an interposed coil spring z, inclosed in the housing afforded by the channel iron.

The springs h normally press the forward blocks c against downwardly-turned stops i carried at the forward ends of longflat springs j lying on the upper faces of the channel irons and adjustably secured thereto at their rear ends by means of screws 7c passing through slots in the springs. By this arrangement it will be seen that the springs j may be sprung upwardly far enough to permit both rollers and their connected blocks and springs to be slid forwardly out of the channel irons or tubes b, for the purpose of Ilatented Feb. f3, i917.

cleaning, repairing, etc. The downwardlyturned stops c' are curved so as to fit around the curved forward ends of the blocks c, thereby preventing the forward pressure of the springs it from pushing or springing the stops to open position. IIhe roller g is provided with a suitable printing surface, such as a rubber cylinder, and the roller f is provided with a suitable ink blanket, ink being fed to this blanket through suitable perforations in the cylinder into which it fits, this blanket being readily removable from the cylinder for purposes of renewal, etc. Ink is introduced into the hollow cylinder f through either one of its hollow pivots or trunnions. Each of these trunnions is pro vided with a screw-plug Z which is adapted to be removed when ink is to be introduced into the cylinder.

It will be observed that the springs 71, keep the blocks e normally pressed against the stops v1, and the rear blocks Z against the forward end of the handle member, thereby normally holding the two rollers away from each other. In printing or canceling, the

'roller g is not pressed against the surface sufficiently hard to compress the springs z, sufficiently topermit it to come into contact with the inking roller, but from time to time as the roller g may need inking, the operator may press a little harder and thus bring the printing roller into contact with the inking roller, the harder the pressure the greater the ink transference. served that with our simple implement the re-inking of the printing and stamping roller is a very simple operation which may be performed during the actual work of printing or stamping.

rIo confine the slidable journal blocks e in the channel irons, we provide the inner edges thereof with longitudinal flanges m, and to permit ready access to the closure plugs Z the outer walls of the channel irons are provided with holes coincident with the trunnions of the inking roller. To prevent the inking roller, while the device is in use as well as out of use, from contacting with eX- traneous objects and thus soiling them, we provide a guard or housing for this roller consisting of two disks n fastened rigidly to the inner faces of the channel irons and slotted at o to permit the journals of the inking roller to have free movement forwardly and backwardly in the channel irons. The edges of these disks are connected across the face It will thus be obof the inking roller by imperforate plates p which are rigidly affixed to the disks and also fastened to the handle member by flanges g and screws r. These curved plates p, together with the forward end of the handle, completely cover and hide the rear half of the inking roller. To protect the front half of the inking roller, we provide two'slidable curved plates s whose rear edges overlap the stationary segments p at all times. rlhese plates s have their edges t bent around under annular flanges on the disks, these interlocked iianges serving to connect these plates s to the disks and at the same time permit them to slide freely in a circumferential manner. l/Vhen the movable cover plates s are shifted as far forwardly as they will go, they leave a slot-like opening across the front face of the inking roller, through which the printing roller is thrust during the inking operation. The forward movement of the cover plates s is arrested by the lugs u on these cover plates coming into contact with the channel irons. When it is desired to remove the inking roller from the implement, the plates s are slid backwardly upon the stationary plates p, to thereby leave the front side of the housing entirely open.

lt will be observed that a feature of importance in our device is that the ink is carried in the device itself, thereby avoiding the necessity of having a separate inking' pad. Furthermore, our inking device is practically dust-proof, being housed in a closed space free from dust, thereby protecting the article being stamped or marked from being defaced by coming into contact with the inking roller, and also preventing particles of dust from collecting on the blanket and being transferred to the printing` roller and thence to the article upon which the prii'iting is made. It will be observed also that by normally holding the printing roller away from the inking roller, ink will flow only when sufficient pressure is applied to compress the springs, and then the ink will be evenly distributed on the printing roller and the quantity of ink transferred thereto will be determined by the pressure exerted.

Having thus described our invention, what we claim is:

l. In combination with a pair of channel housings a handle member,

Copies of this patent may be obtained for ve cents each, by addressing the afliXed to the op-V posite sides thereof and projecting forwardly therefrom and having their open sides facing inwardly; a pair ofV journal boxes slidably mounted in these channels at their inner ends and having an inking roller journaled therein; another pair of journal blocks slidably mounted in the channels at the forward ends thereof and carrying a printing roller; a spring in each housing normally pressing the journal blocks apart to thereby hold the printing roller away from the inking roller; and stops for the forward pair of journal blocks. p

Q. ln combination with a handle member, a pair of channels or housings attached thereto, an inking roller journaled at the rear ends of said housings, apair of slidable journal blocks at the forward ends of the housings, a printing roller journaled in these blocks, springs normally pressing these blocks forwardly to normally keep the printing roller out of contact with the inking roller, and movable stops against which said journal blocks normally abut.

ln combination with a handle member, a pair of channels or housings attached thereto, an inking roller journaled at'the rear ends of said housings, a pair of slidable journal blocks at the forward ends of the housings, a printing roller journaled in these blocks, springs normally Vpressing these blocks forwardly to normally keepthe printingl roller out of contact with the inking roller, and movable stops against which said journal blocks normally abut, said stops being carried at the forward ends of long flat springs secured to and fitting against the faces of the housings.

il. The combination of a handle member, a printing roller and an inking roller and means for mounting them on the forward end of the handle, and a housing for the inking roller consisting of disks covering the ends of the inking roller, curved stationary plates covering the rear side of the inking roller, and curved slidable plates mounted on the disks for protecting the front face of the roller, for the purpose set forth.

In testimony whereof we hereunto afhX our signatures this 29th day of March 1916.V
