ANDREW J. BRADLEY, OF NEW YORK, NY.

ADJUSTABLE PRINTING-STAMP- SPEOIFICATION forming part of Letters Patent N Application filed December 7, 1903. Serial No. 184,018.

To all whom it may concern.-

Be it known that I ANDREW J. BRADLEY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in AdjustablePrinting-Stamps, of which the following is a specification.

My invention relates to printing-stamps; and its principal objects are to provide a stamp which may be adjusted to print various words, numbers, and characters Without removing any parts from the stamp or adding any parts thereto, to simplify and improve the adjustment and setting of type-wheels, to simplify and improve the inking mechanism of stamps, and other objects hereinafter more fully appearing.

My invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification,and wherein like symbols refer to like parts wherever they occur, Figure 1 is a front view of my improved printing-stamp, parts being broken away. Fig. 2 is a side view thereof. Fig. 3 is a rear view. Fig. 4 is a vertical sectional view, and Fig. 5 is a detail view of one of the radial arms. r

The base-frame 1 of the stamp is substantially rectangular, and consists of a horizontal portion and vertical side portions terminating in laterally-extending feet 2 3, the side portions being tied together by rods 4 5.

Within the base-frame 1 a printing-frame 6 reciprocates. This frame is also substantially rectangular, and consists of a horizontal portion and vertical side portions. portions have forwardly-extending integral brackets 7 8. A rod 9 is rigidly mounted in said brackets. A second rod 10 is rigidly mounted near the lower extremity of the side portions, and near the rear edge of the side portions a third rod 11 is rigidly mounted. These rods, in addition to other functions, serve to tie the side portions together and stiffen the frame. The rod 10 projects through the side portions and into slots 12 13 in the The lower end of the print- The side ing-frame is thus guided.

having a flange 15 at its lower end, is secured to the printing-frame near the center of the horizontal portion. through a cylindrical tal portion of the base-frame.

A spring 21 stop-pin 17 and bears against the knob 20, and thus normally holds the printing-frame in its uppermost position. By pressure on the knob the spring may. be compressed and the printing-frame may be lowered to its printing position.

Type-wheels the rod 10, and ed the description The type-wh ery with type.

22 are rotatably mounted upon adjusting-drums 23 are mountupon the rod 9. The wheels and drums are arranged in pairs.

As they are all alike, of one pair will answer for all. eel 22 is provided on its periph- The latter may be of rubber,

metal, or any other suitable material, and the characters may other characters.

jects laterally be letters, numbers, or any A hub or pulley 24c profrom the type-wheel and is At one point A pin 25 pro ects from the type-wheel in register with theindentation, there being space enough between the pi tion to insert t The adjustin n and the walls of the indentahe driving-belt. g-drum 23 is made preferably from sheet metal and consists of a disk having a laterally-projecting integral flange 26 extending almost around its periphery and a radially-extending integral arm 27.

A narrow piece is stamped out of the disk and forms a pin 28. cured at one end to to the pin 28 on the A spiral spring 29 is sethe rod 9 and at the other drum. This spring serves to hold the drum securely in any position of adjustment.

A belt 30, which may be made of any flexible material, but is preferably made of wire,

has one end secured near one of the free ends of the peripheral flange 26.

It then passes then around th into the inden part way round the drum 23, e hub 24: of the type-wheel 22, tation under the pin 25, then to engage the said notches 33.

around the hub 24 again, and then around the other side of the drum 23 and is secured to the other free end of the peripheral flange 26. By this arrangement the type-wheel may be turned in either direction by means of the adjusting-drum. The belt being secured as it is to the hub, slipping is prevented.

An indicating-casing 31 is secured to the brackets 7 8 of the printing-frame 6. This casing is substantially a segment of a cylinder and is provided with a series of notched slots. There are as many slots 32 in the easing as there are type-wheels in the machine, and there are as many notches 33 on one edge of each slot as there are characters on the corresponding type-wheel. Beside each slot the same series of characters 34 appear as are arranged upon the corresponding type-wheel. The radial arms 27 of the adjusting-drum extend through the said slots 32, which are wide enough to permit lateral play of the former. Each arm has a projection 35 struck up upon the side'adjacent the notched edge of its slot The arms being resilient, the projection is disengaged when it is desired to move the arm by merely pressing it aside. Each arm is provided with a pointer 36, consisting of an integral L-shaped projection. The downwardly extending branch is bent back at right angles to the forwardly-extending branch, thus bringing the pointer near the characters.

Brackets 37 38 project rearwardly from the base-frame 1.. They are provided with slots 39 40, opening upwardly. On the outside of the side portions of the base-frame are secured retaining-springs 4:1 42, having holes registering with the lower ends of the slots 39 40, respectively. The upper edges of the springs flare outwardly, so as to be easily pressed away from the frame. A rod 413 projects through said slots and the holes in the springs. This is the journal of the ink-roller frame.

From it arcuate arms 4:4; 45 extend down wardly and carry at their lower ends the inkroller 46. A spring 47, doubled upon itself at the center and having its branches coiled in opposite directions about the rod 43, engages a tie-rod 48 in the arcuate arms 44 45 with its free ends, while its center portion engages the rod 11 in the printing-frame. This spring holds the ink-roller in engagement with the type-wheels. When the type-wheels are pressed downwardly into printing position, the roller is moved aside, as indicated in dotted lines in Fig. 2. The action of the spring tends to move the rod 4E3 out of the slots 39 L0, and hence the use of the retaining-springs.

In use the type-wheels may be set to print diflferent characters, and hence any desired combination of letters, numbers, and characters may be printed.

The device obviously admits of considerable modification within the scope of my invention, and hence I do not wish to be limited to the specific construction hereinbefore described. -For example, while sixteen typewheels have been shown more or fewer may be used. Allthetype-wheels have been shown as provided with letters of the alphabet; but obviously part or all of the type-wheels could be provided with figures, or all of the wheels could be provided with both letters and figures or any combination of characters. The type-carrying members shown are typewheels; but obviously type-belts could be substituted, the pulleys about which the typebelts run being rotatable type-carrying members just as type-wheels are. While the means for adjusting the type-wheels shown and described are preferred, it is obvious that gearwheels could be substituted for the belt and pulleys or drums. Although the ink-roller has been shown and described as mounted in a pivoted frame, it is obvious that the same end could be accomplished by mounting it in curved slots inthe base-frame.
