PIANO-HAMMER.

SPECIFICATION forming part of Letters Patent No. 675,525, dated June 90 Application filed April 2 8 1900.

and State of Alabama,-have invented certain new and useful Improvements in Piano-Hammers, of which the following is a specification,

reference being had therein to the accompanying drawings. 1 i l This invention relates to improvements in hammers for pianos, and more particularly to.,a socket-or joint whereby the hammer.-

.iIs l shanks are easily appliedandadjnstably se-' cured to the'hammer-stem. V i

In the ordinary construction of pianos the joint of the hammer-stem and hammer-shank is made rigid; andthehamm'er stem or shank set of hammers can be applied toan old set r of hammer-shank stems in a shorter time and witha less amount of labor-than is ordinarily used. i v e A still furtherobject of the invention is to provide novel means whereby the hammershank is adjustable in all directions.

Finally, the object'of the invention is to provide a novel socket'or' joint for hammer stems and shanks that will prove strong, du-

" V rable, and eflicient in practice, simple in-con-I struction, and comparativelyinexpensive to manufacture. I

With the above and other objects, in view the invention consists in the details of construetion and in the arrangement and combination of parts, to. be hereinafter more fully set forth and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming a part of this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 is a view in elevation of a hammer and its correspondingparts, showing the joint embodying the invention in use. Fig. 2 is a view in perspective of the joint, said joint being shown in a slightly-modified form; and Fig. 3 is a fragmental view of a hammer, showing the form of joint for use in a grand piano.

In the drawings, A indicates a butt and its shank, as shown at 9, Fig. 2.

of the joint is adapted, as is obvious, to re ceivethe free end of the stem 1 and has also Serial No. 14,656. (No model.)

parts of ordinary construction, and B a hammer comprising a rounded stem 1, a shank 2, and a suitable hammer-head 3. The shank is also rounded and has a shoulder 4 near the top of the hammer-head. The shank 2 is secured to the stem 1 by means of a skeleton joint or socket 5 of suitable light metal approximately T-shaped in construction, the head 6 of which is open at either end and adapted to receive the rounded portion of the shank. Holes 7 are suitably placed in the head of the socket and are adapted to receive screws 8, which are applied after the shank has been properly adjusted. cidental displacement the, shoulders 4: limit the downward movement of the joint. As a further precaution against accidental displacement the upper end of the head may be In case of ac- I 7 closed to limit the upward movement of the holes suitably placed for the reception of tion. v

Ifdesired; the shanks can be covered with a bushing-cloth 11' to prevent the metallic The stem 10' 'screws to hold the stem in itsadjusted posi- 1 joint'frojnrattling and afiecting the tone of the instrument; I

In order to provide means'for engaging the check of the pianolmechanism for use in the type, known as 5 grand pianos, thefront of the joint is provided with a fiat surface,-the operation'ofwhich will be apparent to those skilled in the art. i

The operation, construction, and tages will, it is thought, be fully understood from the foregoingdescription. Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a piano, a skeleton joint or socket hav-- ing a closed end, a hammerhaving a shank fitted in the socket with its end adapted to advan abut the end of said socket, a shoulder formed on the shank engaged by the end of the socket and a stem formed with the socket to receive the hammer-stem.

" In testimony'whereof I affix myi signature in the presence of two witnesses.
