To all whorm 1113 may concern:

Be it known that 1, FI'TENELON PnLIssrEn, a citizen of Haiti, and a resident of Gonaivcs, Haiti, have invented certain new and useful Improvements in Means for Repeating Piano-Notcs, of which the following is a specification.

My invention relates to certain new and useful improvements in means for repeating the notes of a piano, and primarily the inven tion has for its object to provide a device of this nature of a very simple and effective construction which will readily and effectivcly serve its intended purposes, and in which means are provided whereby the note or tone of a piano string may be repeated automatically.

In its more subordinate nature, my invention comprises certain novel construction, combination and arrangement oi parts all of which will be first described in detail and then be specifically pointed out in the ap pended claims, reference being had to the accompanying drawings in which Figure 1, is a diagrammatic elevation of my invention in action. view showing the position of the parts when at rest. Fig. 3, is a similar view to Fig. 2, the supplemental hammer being locked out of action.

Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the fig ures, it will be noticed that the main hammer 1, which may be of any approved con struction, comprises the neck 1 and the head 1", which is felt-covered as at 1" in the usual manner.

2 designates the iano string which is adapted to be struck y the hammer 1 when its corresponding key (not shown) is touched to operate the hammer action and bring the hammer against the string to vibrate the same and sound the proper note.

3 designates a supplemental hammer which consists of the body portion 3 whose striking end 3 is covered with felt 3 and Whose rear end 3 has a felt cushion 3 to seat upon the main hammer 1, in a manner presently explained. The hammer 3 is sup ported on the hammer 1 by rods st or any other suitable connection, which rods 4 are connected at one end as at 4 to the main hammer and as at 4' t0 the supplemental hammer 3, the rods 4 being of such nature,

Fig. 2, is a similar and the supplemental hammer 3 curved at 3* in such manner that when the hammer 1 has struck the string 2, the supplemental hammer 3 will fly against the string 2 and repeat the note.

In order to aid the return of the supplemental hammer to its normal position against the main hammer, I may provide a light coil spring .5 which is secured at one end 5 to the main hammer 1 and at the other end 5" to a pin 5 on the supplemental hammer 3.

in the practical a plication of my invention a supplemcnta hammer may be provided for each of the main. hammers, or on such predetermined ones mar he desired, say, for instance those of the bass clef. \Vhen it is desired to render the supplemental hammer inoperative, I In ay secure the same from operation by any 8. )proved means, such for instance, as a supplemental wire member 6 which may be secured at one end and carried by the main hammer 1, as at 6", and have its other ends bent into apertures 6 in the supplemental hammer 3, so that when the parts are looked as shown in Fig. 3, the supplemental hammer will be inoperative and only a single set of vibrations be set up in the string 2 when the hammer strikes the same. V

In operation when the parts are at rest the supplemental hammer seats with its butt on the mainlismmer, as shown in Fig. 2, and as soon the proper note of the pmao has hecn struck, the main hammer i will strike the string 2 and rebound to the osition shown in Fig. 1. Immediately a ter the main hammer 1 has struck the strin' .2 the supplemental hammer will fly out an strike the same string as shown in Fig. 1 and will he immediately returned to its normal position against the main hammer, by the spring 5 and rebound. This action of the supplemental hammer is what produces the repetiticn of the note and if the installation is not defective such repetition will take place without confusion.

Regardless of the position of the main hammer 1 after it has struck its respective string the supplemental hammer will always return to its normal position with its butt against the main hammer, as shown in Fig. 2.

From the foregoing description taken in connection with the accompanying drawings it is thought the complete construction, opcration and many advantages of my invention will be rradily lllldOlStOUll by those skillcd in the art to which it appcrtaius.

\Vliut I. claim is: r

l. A mcztns l'or rcpoating the notcs of a piano comprising a supplcmcntail hmumcr combincd with it main hznnmcr and :Lctimtcd by the movcmcnts thcrcol'.

2. A dcvicc of thc class duscribcd, comprising a main and a supplcmcntail hammer, and. mcuns for supporting thc supplcmcntitl hummci. on the main llmnnicr.

3. A device of the class described, coniprising a main and EL supplcmcntal hammer,

mczms [or supporting the supplcmcutnl lHtllllner on tho main hammer, and moans for normally holding the supplemental lhtlllllltl scatcd against the main hmnmcr.

1. A dcvicc of thc class dcscribcd, comprising a main and a Hll])])l(]]l0]ltttl hmnmcr, mcmis for supporting thc supplclncntuil hammcr on thc muin hznnmcr, and moans lor normally holdiiug thc Hll])])l(lll(lltitl lHtlllHHI' scatcd against thc main hainuncr, and for rcturning it to said svutcd position al'tcr its action.

5. A. dovico of thc class dcscribcd, LUlllprising a supplcmcntul hammcr combincd with tho main hinnmcr, and iui'ztns l'or actuting thc supplcmcntal hainmcr by tho movcmcnts ol' thc n'ztin hzunmgr.
