.tous u'. E. einer., or Viersen, nerr Praise-rr SH COLUMBA, CA NADA.

To allied-om 'it 'may concern.'

Be it .known that i, Joins aises, a suhiee't of theling et' Great Britain, and resident of Tiictoria, in the Frovince ot British Columbia and Dominion oi Canada, have invented a n.y and lniproved 'ianol-lamn rner, which the following is a full, clear, and exact "iption 'lnis .inv

ion relates to'pian'o hammers, and more par cularly such. as have heads provided .3h adjustable means tor removally mounting the felt strips used in striking the Wires.

in obiect ot' "tte invention is to provide a device of the class described, having a head resiliently supported on the hammer shank, thereby causing' more decided blow to he struck, and at the saine time permittinglof a quicker rebound than in the ordinary piano hammer.

further object of the invention is to pro vide a no hammer having adiustahle means for removably incur ting the telt strip, thus allowing different materials for producing ditierent effects and tones, to he easily substituted.

'l he invention consists in the construction and combination of parts to he more full;7 described hereinafter and particularly set fort-h in the claims.

Reference is to be had to the accompanying drawings forming a part of this speciii-v cation, in which similar characters ot' reference indicate corresponding parts in all the views, and in which Ligure l is a side elevation ot the invention; FivzZ is a cross section on the line l2`2 Fig. i, .and Fig'. 3 is side elevation of a Inodiiication of the device, the liller hein oin""ted.

tiefere proceeding to niore detailed dei scription ot' my invention, it should be understood that l provide a piano hammer having a head resiliently mounted on the herinner shank, and which has adjustable ineens to permit otl the removal of the telt strip used in striking the piano Wires the felt strip being adiustahly hold 'in position, can he easily shifted when the striking surface hecomes worn out, so that afresh surface will'` 'he presented tor striking` the Wires. F urther, as the feltstrips are easily removable, other strips olZ dill -ent material can be substituted to prodvr different tones,

hammer hack stop l, a hammer butt 2, herinner shanli 3, and a hammer head 4l. The latter has a hase 5 preferably integral With the hammer shank 3, in which openings G are located. .Arranged Within these opere ings are supports 7, having their upper ends .laterally disposed to form iingers S. Blocks 9 and l0 respectively have openings at their sides, in which the iingers 8 ofi the supports 7 are arranged. l'lhe rear supports 7 extend to the rear bloei; l0, the forward supports extending; to the forward block 9, the openings 6 being arranged at angles with each other for this purpose. rl`he clock 10 presents a tapered, curved surface at one end, t e other end heling substantially straight. lhe lolocli 9 is somewhat larger than the block 10, and presents a tace substantially paralisi to the hloclr -iO at the tace adiaceut thereto. Arranged between these blocks and having one end 12 arranged within an opening. i3 in the block l0, and having it other ond le. suitably threaded to engage a similarly threaded opening l5 in the block 9, is spreading screw 16, having a manual grip 18 at the center thereof. This screw is preferably constructed of aluminum or other suitable material. A pin 19 is located on the end l2 of the sereW and serves to engage 'grooves 2O in the block 10, so that the screw 'will he held against rotation after the blocks have been adjust-ed in position. of ,some suitable material, such as felt or'. the like, and presenting a rounded surface at its outer end, is arranged adjacent to the 'iront face ot' the hloclr Q, which face is tapered so that' it tends to spread the filler as it is as: justed. Encornpassing the iiiler 'and 'the blocks is an adjustable endless strip, pret`- erahly composed. of an outer and inner felt 23 and 2e, respectively.

In the operation of my 9 and l0 are adjusted device, the blocks and firmly hold the telt strip 1n position.. When it isl necessary to remove the latter, the screv'isrotated so that the blocks Aare approached, and the strip released. The supports 7 are then Withdrawn from the openings El in the blocks,- and the strip can then he easily' talrenl troni the same. As shown moet clearly in Figi, the ports '.7 more deci ed blow is possih aand at the encjv oi the",T are et as supports is incr erstere? eonstro ed so th mea or t? A filler 21,.

by ine-ans ofi the. spreading screwx so that they are forced apa-rtsame time the resilithe like, a quicker rebound after the blovs?` has been struck is produced. The felt strip being easily adjustable, can be shifted so that When the striking surface becomes` Worn a new surface is presented for striking tlie wires.

lt should be noted my hammer iiller Z1 may be emitted, felt strip covering the blocks, clearly in Fig. 3.

Having tb us described my invention, what claim as new and desire to secure by Letters Patentis:

saving only the as shown most 1. In a device of the class described, a v

hammer shank, and. ahead carried thereby,

that the hammers in l one another,

blocks, and a strip arranged about said. the piano are of different sizes and that in f'iiller and said blocks.

for producingtreble notes the si. in a device of the class described, a hammer shank, pairs of supports carried by said l: animer shank, a block arranged between tine ends of said supports of eacli pair, means for moving said supports relative to a iiller at the end of one et' said 5. ln a piano hammer, a hammer shank, a base integral therewith, pairs oi supports irremovably carried by said base, said supports lhaving their upper ends laterally disposed, blocks having openings on their adjacent sides and mounted between said laterally1 disposed ends, a spreading member said head comprising relatively adjustable blocks, and a felt band niovably encompassing said blocks. A

2. .In a device et the class described, a

hammer shank, resilient supports carried by said hammer shank, blocks arranged at tine i member is operated to loosen said blocks,

ends of said supports, a felt carried by said blocks, and means for adjusting said blocks with respect to one another;

3. In a device et the class described, a hammer shank, pairs ot supports arranged upon said hammer shank, blocks removably arranged between the ends of said supports i oi eacii pair, a felt carried by said blocks,

and means for adjusting said blocks.

having its ends arranged Within said open Lgs el" said blocks, one of the ends of said member being tiireaded, whereby it serves for trie adjustment of said blocks with respect to one another, a l'ront of one of said blocks, and an endless felt strip arranged about said iiller and said blocks and adjustable when said spreading said blocks serving to tighten said strip.

In testimony whereof I have signed my name to tizis specification in the presence of two subscribing Witnesses.
