HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 449,076, dated March 24, 189 1. Application filed July 1'7, 1890. Serial No. 359,051. (No model.)

, To all whom, it may concern:

Be it known that I, HENRY HOWARD, of Brookeville, in the county of Montgomery and State of Maryland, have invented certain new and useful Improvements in Hand-Stamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a side view printing-stamp for marking or canceling purposes. Fig. 2 is a plan view partly broken. Fig. 3 is a transverse vertical sectional view through the cam-shaft and connected parts. Fig. 4 is a detail. Fig. 5 is a modification as to form of frame.

This invention is an improved hand or power stamp or machine for simultaneously printing upon a letter or postal-card the name of place of mailing and date and canceling the stamps, or for any other purpose to which ordinary hand-printing stamps are employed; and its objects are to provide a partly-automatic stamp-block holder whereon a number of stamp-blocks may be mounted and which may be quickly shifted to print from either of such blocks; to removably secure such stamp-blocks to the holder and to accurately and positively guide the stamp-block and reciprocate it from the inking-pad to the point where the impression is made, and to automatically return the holder and stamp-block to inkingposition and out of the way; and to these ends the inventionconsists, essentially, in an oscillatory stamp-block holder mounted upon a rotatable cam by which the holder is lifted and reciprocated back and forth, and in other novel details of construction and combination of parts hereinafter fully set forth and claimed.

Referring to the drawings, letter A designates a revoluble shaft journaled horizontally in proper bearings in side pieces of a frame IV of any suitable construction.

B designates a cam-disk secured eccentric.- ally to said shaft and having a peripheral channel I), in which is fitted loosely an annu- 50 lus C, forming of my improved to the upper side of which are seen red vertical socket-pieces c c, that are arranged radially in relation to the axis of the disk and annulus, but two socket-pieces being shown in drawings. To the lower side of annulus C are attached socket-pieces D (1, respectively, diametrically opposite sockets c 0. Piece D has two sockets D, attached to laterally-projecting pieces, while piece (1 has but a single socket. These are all provided wit-h setscrews d or with other devices for engaging the shanks of stamp-blocks S S s.

E designates an oscillating guide-rod that is suspended from and guided by a pin 6, attached to an upstanding arm to of themain frame, which rises above and curves toward shaft A. The upper end of rod E is slotted to engage the pin freely and allow the rod to oscillate transversely above the shaft and to reciprocate vertically. The lower end of the rod is adapted to engage in either of the socket-pieces c c. Below the stamp-holder and to the inside of shaftA is an inking-pad, with which the lowermost stamp-block attached to the holder is adapted to contact and receive the necessary supply of ink. \Yhen the guide-rod E is engaged with either of sockets c c, it brings ,such socket normally into vertical position,

and consequently the stamp-blocks attached So to the lower socket-piece diametrically opposite that engaged by rod E will be lowermost and contact with the ink-pad. The disk is so mounted on the shaft that when the stamp-block is'on the pad a line drawn between the block and pin e will about intersect the center or axis of the disk, and the parts will stand to the inner side of shaft A within the frame. It now shaft A be rotated to throw the disk upward and outward, it will lift the stampholder and move it outwardly to the position indicated in the drawings in Fig. 5. Rod E prevents the holder tn rning with the disk, but permits it to move the stamp-block from the ink-pad to the point 5 wheretheimpression is to be made, the stampblock traveling through a nearly semicircu .luar arc, first rising from the pad until it part of the stamp-block holder,

reaches a point beneath rod A, and'then descending into or toward the impression plate or table. The half-revolution of shaft A is about all that is necessary in taking an impression from the stamp. When the shaft is released it is turned back into normal position by springs, preferably as by the convolute spring F, which is coiled around one end of the shaft and is connected thereto and to the frame, so that it is tensioued when the shaft is rotated forwardly and automatically returns the shaft to first position, thereby bringing the stamp-block back into contact with the pad. For post-offices the double socket-piece is useful, as the canceling-stamp block can be attached to one socket and the time-stamp block to the other and impressions taken from both at a single operation.

If it is desirable to shift theholder to print from another stamp-block, the rod E is disengaged from the socket-piece and the holder turned on the disk until the socket-piece diametrically opposite the stamp desired to be used is uppermost. Rod E is engaged therewith and the machine is ready for operation, as described. This shifting of stamps can he obviously done with ease and rapidity. The stamp-blocks being removably secured to the stamp-holder, they can be readily removed or interchanged or replaced by others, as desired.

Shaft A is operated to produce the impression by any suitable means, as shown. There is a crank-arm G attached to one end thereof. If desired, a disk or pulley might be secured to the end of the shaft and a cord run over the same to a treadle to be operated by foot, or instead of securing the crank direct to the shaft a pinion might be placed on its endand engaged by an oscillating segment or other gear attached to the frame and adapted when depressed slightly to cause a proper rotation of the shaft. The rod E might pass through a vertical slot in the arm to instead of being attached, as shown, or'otherwise arranged, provided it was allowed an oscillatory and reciprocating movement, as described.

The inking-pad is preferably mounted in a circular dish II, that is centered on a pin or pivot I, and this dish has an upstanding peripheral toothed flange, which is engaged by a reciprocating dog J, pivoted to the lower end of an oscillating lever K, pivoted on a pin at one side of the frame below shaft A, and having its upper end engaged by a cam on said shaft, by which lever K is rocked when shaft A is rotated and dog J reciprocated, so as to gradually rotate the ink-pad.

In front of shaft A and below the stampholder is a table or bed L, upon which the matter being stamped is laid to receive an impression. This table may be supported on springs, if desired, so that if the packages are unusually thick they can be depressed to permit the stamp to make a clean impression thereon, and preferably the ink-pad is covered with a stationary plate N, provided with an opening a at the proper point just large enough to admit the stamp-blocks from which impressions are tobe taken to contact with the ink-pad, while the main body of the pad is protected from dust.

Any number of socket-pieces may be arranged on the holder that is desirable and which its size will admit of. In the practical operation and construction of the stamp the guide-rod might be arranged at any angle to the base and radial to the disk, and the positions of the socket-pieces in relation to each other would be changed accordingly without affecting the functions of the rod, which are simply to prevent rotation of the annulus on the disk and to shift the position of the annulus in relation to the disk. The holder being operated by a cam-disk, as described, in making an impression will force the stampblock down directly and with a force varied only by the power applied to rotate shaft A, so that a clear impression will be produced.
