ROTARY STAMPING DEVICE.

To all whom it may concern:

. Be it known that I, CHARLES DIMEGH, a citizen of the United States, residing at West Point, in the county of Orange, State of New York, have invented a new and useful Rotary Stamping Device; and I do here- 4 by declare the following to be a full, clear,

- e bya number of printing surfaces, such as and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.-

The present invention relates to a rotary stamping device, and has for its object to provide a device of this characterwhich embodies novel features of construction whererubber stamps, can be mounted upon the periphery of a drum and any selected one of the printing surfaces quickly inked and brought into proper position for stamping. Further objects of the invention are to provide a" rotary stamping device-which is simple and inexpensive in its construction,

which admitsof the printing surfaces being quickly changed, which is very compact in its design, and which can be, used without danger of soiling the fingers.

With these and other objects in View, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, thenovel' features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in

which Figure 1 is a side elevation of a rotary stamping device constructed in accordance with the invention, the stamping drum and indicating pointer being shown in their normal positions. Fig. 2 is a view similar to Fig. 1, showing the indicating'pointer in theposition assumed preparatory to rotat Specification of Letters Patent.

ment of the invention, the numeral 1 designates a stamping base which is provided at one end thereof with a standard 2. Correspending levers 3 are pivotally mounted at points spaced from the rear ends thereof, as indlcated at 4, upon opposite sides of the standard 2. 'lhe rear ends ofthe levers 8 are connected to springs 5 which normally tend to swing the forward ends of the levers upward and lift the printing drum away from the stamping base 1. The extremities of the levers 3 are extended downwardly at 3 and connected by a shaft 7 which has the printing drum 6 rigidly mounted thereon.

A fork 8 straddles the printing drum 6 and has the arms thereof pivotally mounted upon the shaft 7, the arched end of the fork being provided with a handle 9, while the arms thereof terminate at their free ends in resilient pointers 10 which are used to inclicate which one of the printing surfaces on the periphery of the drum is in operative position. One end of the shaft 7 terminates in a wing or finger piece 11 by means of which the shaft and drum can be rotated to bring any selected one of the printing surfaces into operative position. The opposite end of the shaft 7'ter1ninates in a head 1.2, and a spring 13 is interposed between the said head and the adjacent lever 3, thereby causing the ends of the printing drum 6 to be frictionally gripped by the fork ,8. By grasping the handle 9 of the fork 8 and forcibly rotating the printing drum 6 through the medium of the finger piece 11, any selected one of the printing surfaces on the periphery of the drum can be brought into operative position, and the frictional engagement between the fork and the drum is ordinarily sufficient to hold the parts against accidental displacement.

The periphery of the printing drum 6 is provided with a series of longitudinally extending undercut or dovetail grooves or recesses 14. Correspondingly shaped sheet metal clips 15 are adapted to be slipped removably into the recesses 14, and these clips 15 are designed to carry blocks 16 upon which the printing surfaces 17 are mounted. These blocks 16 are interchangeable and removable, so that the printing surfaces carried by the drum 6 can be changed as often as desired. One end of the drum may be provided with a pair of spaced projections or knobs 18 opposite the base of each of the dove-tail recesses 14. The resilient pointer 10 of the fork 8 will ride over the projections 18 when the drum 6 is forcibly rotated through the medium of the finger piece 11, although when any particular one of the printing surfaces is brought into operative position, the spring pointer will seat itself between the corresponding pair of projections 18, thereby locking the fork and drum against relative rotation.

An inking roller 19 is journaled between a pair of arms 20 which project forwardly from the upper end of the standard 2, and the springs 5 normally operate upon the levers 3 to swing the printing drum 6 upwardly toward theinking roller.

Then it is desired to use the stamp, a selected one of the printing surfaces 17 is rotated into position opposite the pointers 10 of the fork S. The handle 9 is then swung downwardly and forwardly to bring the printing surface into engagement with the inking roller 19, after which the handle 9 is swung upwardly to bring the fork 8 into a substantially vertical position with the selected printing surface properly inked and atthe bottom of the printing drum. The paperor article to be stamped may be inserted between the drum 6 and base 1, and

' the printing surface brought into engagem'ent therewithby pressing downwardly on the handle 9. As soon as this pressure upon the handle 9 is released, the springs 13 will again lift the printing drum into inoperative position, whereupon the paper or other article which was stamped can be removed. This operation can be very quickly repeated, as often as desired, and it .will be obvious that any desired one of the printing surfaces 17 can be very readily brought into proper position for use. If desired, the pointers 10 may carry counter-weights 21 for causing the fork 8 to automatically as sume an upright or vertical position as soon as released.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1'. A rotary stamping device, including a base plate, a standard, a pairof levers pivotally mounted upon the standard, a printing drum journaled between the levers, a series of independent printing surfaces mounted on the periphery of the drum, a fork straddling the drum and adapted to grip the ends thereof at adjusted positions, ahandle on the fork for swinging the printing drum toward the base plate, and inking means.
