MARKING-STAMP,

SPECIFICATION formingpart of Letters Patent No. 331,475, dated December 1, 1885.

Application filed July 6, 1885.

To all whom it may concern: 1 Be it known that I, FRANK M. BULKLEY, a citizen of the United States, residing at; Bridgeport, in the county of Fairfield and; State of Connecticut, have invented certain? new and useful Improvements in Marking- Y Stamps; and I do herebydeclare the following 1- to be a1full, clear, and exact description of the l invention, such as will enable others skilledl in the art to which it appertainsito make and use the same. I 1 My invention relates to the general class of l stamps the uses of which necessarily require that frequent changes be made in the letters, and has for its object to devise a novel construction of changeablestamp,whichwill perrnit of almost unlimited variation of letters or I figures, and will be easy to manage, durable, and economical in cost.

With these ends in view I have devised the improved construction which I will now describe, referring by letters to the accompanying drawings, forming part of this specification, in which- I Figure 1 is a plan view of the device in operative position; Fig. .2, a central vertical section; Fig. 3, a transverse section, and Fig. 4 a side elevation.

Similar letters denote the same parts in all the figures. V 1 A is the type-wheel, which may be of any desired construction or material. I preferably, however, turn it in a single piece from a block of wood.

B represents flanges upon the wheel to which the type-holders are attached.

In the drawings I have shown the wheel as having but two flanges. It will of course be understood, however, that three or any other suitable number of flanges may be used.

Cis the frame-work, which consists simply of a pair of side pieces, 0, joined at one end, to which a handle, D, is attached.

E represents the type-holders, which consist simply of base-piece E, and side springs, E the operation of which will be more fully explained. These type-holders may be made independently of each other, butI preferably make them in a single strip, as shown, which extends entirely around the flange of the wheel. This strip of type-holders is preferably formed Serial No. 170,737. (No model.)

in dies-that is blanked out and struck up to the desired shape. They are attached to the flanges of the wheel by nails or pins, as indicated in Fig. 1.

any suitable manner. I preferably,however, use wooden blocks, the letters themselves beingformed of rubber and attached to the blocks in the usual manner. The types are held in position by being pressed in between springs E the springs being slightly curved, as shown in-Fig. 3, and being stiff enough to hold the letters firmly in position without the use of any other securing device.

F represents loops at the ends of .the types, which serve as handles, so that they may be attached or detached without danger of inking the fingers.

G represents guard-rings, which I place outside of the flanges. These rings maybe made in any suitable manner, but are preferably cast in a single piece, and are provided with arms G, which are bent inward and serve as a means of attachment to the type-wheel, as shown in Fig. 3. These rings project out slightly beyond the edges of the side springs, so that in use there is no danger of the springs themselves coming in contact with an article being marked, after the impression of the types is completed, as the hearing will be upon the peripheries of the rings. One of the rings is also provided with a bolt-hole, H.

K is a spring-bolt, which is secured to the frame-work in any suitable manner, the end of which is adapted to spring into hole H at the completion of each revolution of the typewheel. The outer ends of the side pieces of the frame-work are provided with slots L, extending inward toward the handle, in which the journals M of an inking-roller, M, bear.

N represents an arm at the end of each side piece, projecting either upward or downward at any angle to the side piece. These arms are provided with slots N, in which the journals 0 of a distributing-roller, 0, rest.

1? represents disks at the ends of the journals, through which said journals loosely pass, and are slightly headed over outside of the disk, so that while the journals are free to rotate in the disks the disks themselves cannot slip off from the ends of the journals.

F represents types, which may be made in The ends of the journals are preferably turned down slightly, leaving shoulders, (not shown,) against which the disks rest.

Q, represents springs, one of which connects each, pair of disks, and another connects the disk at each end of the inking-roller journal with the side piece of the frame-work, as clearly shown in Fig. 4. The action of these springs is to keep the distributing roller pressed against the inking-roller and the inking-roller pressed against the faces of the letters. The bottoms of slots L, however, prevent the inking-roller from being drawn down far enough to'jcomelin contact with the ends of springs E when vacancies occur in the letters.

The type wheel is journaled in the side pieces in any suitable manner. I preferably,

. however, use wood-screws, R, which pass tion.

[ordinary wear of the journals. In use the desired letters or figures are placed in the proper position in the type-holders, the roller inked in the usual manner, and the device is ready for use, it being shown as in operative position in Fig. l.

- As stated above, at the completion of each revolution of the wheel the end of the springbolt engages hole H in one of the guard-rings, thus locking the wheel against further rota- The bolt is ordinarily provided with a thumb-piece, as at K, by which it is operated. If it is desired to make another impression, it is simply necessary to press the bolt outward until its end is disengaged from hole H.

In use the end of the bolt rests against the guard-wheel, so as to be ready to spring into the hole the instant the revolution is completed. When it is desired to change letters or figures, they are simply lifted off by loops F and new ones supplied in their places. No locks, bolts, or clamps are required to hold the types in place. I have found in practice that the simple pressure of the side springs is quite sufficient.

I do not desire to limit myself to the exact details of construction as illustrated in the drawings, as it is obvious that the construction may be greatly changed without departing in the slightest from the spirit of my invention.

I claim- 1. A marking-stamp consisting, essentially, of a type-wheel, spring type-holders secured to the periphery thereof, and detachable types adapted to engage said type-holders.

2. A type-wheel having flanges and spring bolt-hole at the end of each revolution of the type-wheel.

4. The type-wheel and one or more strips of type-holders consisting of base and side pieces secured to the periphery of the wheel,

in combination with detachable types adapted to engage the type-holders.

5. In a marking-stamp, detachable types having loops which serve as handles, in combination with a type-wheel having one or more series of type-holders secured to its periphery, said typeholders consisting of a base and a pair of slightly-curved springswhich bear upon opposite sides of the types.

6. The type-wheel having springs 15) secured to its periphery, and the guard-rings 1 having arms by which they are secured-to the type-wheel, one of said rings having a bolthole, in combination with suitable frame-work in which the type-wheel is journaled, and which carries a spring-bolt adapted to engage the type-wheel at the completion of each revolution.

In testimony whereof Iai'fix my signature in presence of two witnesses.

FRANK M. BULKLEY.
