HAND-STAMP.

SPECIFIGATION forming part of Letters Patent No. 283,583, dated August 21, 1883.

Application filed April 14, 1882. (N0 model.) 1

To all whom z't may concern: 7

Be it known that I, HERBERT G. Donn, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Hand-Stamps, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my improved stamp'canceler. Fig. 2 is a central longitudinal section. Fig. 3 is a bottom view. Figs. 4, 5, 6, 7, ends are detail views.

Similar letters of reference are used to designate like parts throughout the several views.

A represents the handle of my stamp-canceler, having a projecting cancelingwheel, B, and provided with a ferrule, O, which is held in position by the bolt D, which also forms the axle upon which the canceling-wheel revolves. 7

Immediately above the canceling-wheel is placed the inking-wheel E, whose axle has vertical play within slots F F, cut in the side pieces, I I, on each side of the recess G, in which the wheels B and E are placed. The inking-wheel is kept in constant contact with the canceling-whee], and with canceling-wheels of different sizes, by means of the spring H, secured within a recess cut in the checks or side pieces, I I, below the slots F, and having its upper end attached to or encircling the axis of the inking-wheel, i is seen in Fig. 8, whereby a downward pressure is constantly given to the said inking-wheel.

The upper part of the handlev A is made hollow, so as to form an ink well or reservoir, J, into which printers ink is put through an opening at the top of the handle, ordinarily closed by the screw-plug K.

Atthe base of the ink-well there is formed the tube or passageL, closed bya stop-cock, M, and having placed. within its'lower end the distributing=pad N, which may be made of any elastic or semi-elastic substance, and which should always be in contact with the inking-wheel and keep it charged with a sufficient quantity of ink, the flow of which can be regulated by the stop-cock M.

The canceling-wheel is formed of a short cylinder of suitable metal, having its rounded surface scored by a series of parallel grooves, O, which are intersected byparallel transverse grooves O, which give an impression of a series of quadrangular dots or small squares upon the surface of the paper over which the printing-wheel is rolled. The faces of these serrations may be greater or less in size, the object being to indent the paper or stamp and not cut through it, so that should the ink be washed from the stamp and an attempt be made to smooth out or remove the impressions or indentations from the stamp, in order to restore it, that it may be used again in fraud, it will be impossible to do so successfully, as the impressions or indentations will still remain.

hen it is desirable to print with removable type, I construct the canceling-wheel in the form shown in Figs. 5, 6, and 7. The wheel is made in two parts, I Q, one part, I, having a central projection, R, provided with a few turns of ascrew-thread, as seen in Fig. 5. The types S are made with their sides flat and parallel; but their front and rear edges are made beveled, inclined, or wedge-shaped, as is seen in Fig. 4, the apex resting against the smooth side of the projection R. The opposing faces of the two sections P and Q are made with circular serrations, as seen in Figs. 6 and 7, by which construction a better and firmer hold is obtained upon the type when the two sections'are screwed together.

It will be seen that by withdrawing the bolt or pin D'and removing the ferrule 0 easy access is had to the inking and canceling wheels when it is necessary to clean or inspect them.

hen it is necessary to change the canceling wheel only, it may be accomplished by simply removing the pin 1), when the wheel B may be easily removed from the handle without also removing the ferrule.

By means of this device letters may be post marked and their stamps canceled in a rapid and effective manner, it being possible with it to cancel several dozen stamps by one motion of the hand.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

In a handstamp, the combination, with the handle A, inclosing an ink-reservoir, J, and provided with vertical passage L, cock M, and pad N, of the detachable ferrule C, In testimony that I claim the foregoing I slotted cheek-pieces I I, arranged therein and have hereunto set my hand this 3d day of 10 forming recess G, the inking-Wheel E and April, 1882. canceling-wheel B, journaled in said recess,
