IMPROVEMENT IN HAND CANCELING-STAMPS.

Specification forming part of Letters Patent No. 139,486, dated June 3, 1873 application filed May 21, 1,672.

To all whom it may concern: l

`Be it known that I, ERNEST H. THOMAS, of the city of Louisville, county ofJei'erson, and State of Kentucky, have invented certain Improvements in a Hand Canceling-Stamp, ot' which the following is a speciiication:

The object of this invention isto provide a neat and simple device for hand printing or canceling purposes, that will be self inking, 'and at the same time make as neat and sharp impressions as any of the best printing presses now 1n use.

lFigure 1 lof the drawing is a perspective view ot' the device when thrown open, showing the stamp-cylinder, inking-rollers, and ink-fountain. Fig. 2 is an elevation view ot' the device when closed up, showing the end of the stamp-cylinder and link attachments, also the operating-stem and spring thereon, in section. Fig. 3 is a section of' the stampcylinder, showing the stamp and pieces of gum under it. Fig. 4 is a perspective view of the cylinder, showing the stamp as set therein. Fig. 5 is a sectional view of the stamp-plate, showing how the names and dates are inserted therein.

In the drawing, A is the handle, which is generally made of wood. B is the frame or jaws of the device, all of which are made of metal, of the required thickness or strength, and in form as shown in the drawing. C is the type-form or stamp-cylinder, all ot` which is made of metal, about two inches long and one and three-eighths inch in diameter, closed at the ends. -In form it consists of about two-thirds of a circle, leaving one side Hat in order to admit of an opening sufficiently large to receive the type or stamps, and also deep enough to give room for pieces ot' gum under them in order to be elastic to relieve the shock in stamping; but when dies are used for stamping, they are formed on a plate of suitable shape and size, and made to slide into the cylinder through grooves cut iu the inside edges, but at the same time made to rest hard on the gum under it; but when type alone are used, one or more pieces of the gum are taken out and the type-form set in their places, and fastened in any suitable manner. D Dl are inking-rollers, one of which is made of the composition ordinarily used for such purposes, `while the other is made of common felt, and only acts as a conveyer for inking the e 'linder, and not the type. H H are the arms of the hiking-roller, one end of which is made to work loosely on a pin in the ends ot' the cylinder-shaft, so as to vibrate easily, while in the other end there are slotopenings in which the journals ot' the roller work in order to permitit to raise or lower iu passing over the uneven surface of the cylinder and stamps in the process ot inking. It is provided with a spring, din the openings ove'r the journals tokeep it up against tlrje surface ofthe cylinder and stamps in inking. G G are links at the ends ot' the cylinder, one ot' which is made to work loosely on a pin in the arms H H, about one-haltl inch from the lower end where it connects with the cylinder-shaft, while the other connects with the ends of the cylinder in a similar manner the same distance from the center, in order to answer as a crank to give motion to it and the roller D for the purpose ot' inking the stamps. The upper ends of these last-named `links G G are slipped over and made to work loosely on the ends of a small bar working through slot-openings in the side of the fra-me, so as to permit it to be raised or lowered..

This bar constitutes the cross-piece ot' the operating stem L, to which it is `attached at thie center. The stem L extends up through the handle, and has a spiral spring, N, around it within the handle for the purpose ot' replacing it after being pressed down to ink the stamps J, which is done by pressing down the stem L while the stamp is raised from the paper. By this means motion is transmitted to. the cylinder C and roller D, causing the A two surfaces to revolve on each other, and thereby distribute the ink over the stamp at each impression. B is the sta-nd or arm of the ink-conveyer roll D. This arm connects with a bar across the back cap, and is provided with a spiral spring, S, attached to the cap to hold the roller D in position. F is` the ink-fountain, which is made of metal inclosed at all sides, leaving only a small space at the inside edge for the distributingaoller P to work in. This roll is made of ordinary felt. Both the iukfountain l and conveyerroller D are fastened to the cap for convenience in supplying it with ink, but when closed up ready for use, the conveyer-roller D rests on the cylinder C, and also at times against the'fountain-roller P; and as the cylinder C turns, ink is distributed over its surface, which is again taken up by the inking-roller D and transferred to the type or sta-mp as it passes over them. J is the stamp and plate, the die of which may be provided with any suitable design, but when used for canceling letters or other similar purposes, an opening is left in the plate, where the date, postmasters name, and that of the different mails should appear, and a small die inserted containing these names and date in such a manner as to be easily chan ged Without loss of time, they being held in their places by a ange on the under side, countersunk in the plate. R is the die containing the names or date.
