ExE'RcIsIne APPARATUS roRnsE BY M sIcI Ns IHE'HAN-D.

I To all whom/it may concern;

' yBe it known that'I, HARRYIOSTROVSKY, a

subject of the Emperor of Russia, residing";

at 50 Leinster Gardens, 'BayswatenfLondon, England, have invented a new'and useful Exercising Apparatus for use by Musicians for-"Developing the Musclesof the 'Hand, of V which the following is a specification.

" 'My invention relates to apparatus'foruse by violinists for 'exercisingmuscles brought into use when playinginstruments, of the keys or plates which "would represent the kindwherein, spring plates or keys are employed on, which the fingers of the left hand of the user operate and which are arranged 1 to slide along a bar, frame or stem repre-' senting the key board of the instrument.

According to my invention I -make-the plates or keys so that they are removable fromthe key board or fingerboard and the resistance of the springscan be varied by removing and replacing the springs or by the provision of means for adjusting such tension thereof. The part of the frame, bar

or stem in which slide the plates or keys is I removably connected to" the part carrying the chin-rest sothat the said parts can be detached 1 and joined together at a right angle, in which 'position the chin-rest can then serve as a s upport for the hand, wrist or fore arm and the apparatus can then be used for exercising the muscles used .by

pianists, the rest or-supportbeing movable,

along the bar or stem in order thatits position may be adjusted to'the users requirements. When'the apparatus is required for use by pianists it is advantageous to employ two" similar parts of the frame carrying the white andblack keys respectively of a piano, such parts being securedtogether." 'Means are provided for stopping any one or more of the keys or plates from being "actuated by the fingersinorder to-developindependenceofaction of the'other fingers." Upon the baror stem in proximityto the rest or support I [provide an-adjustable spring'device in which theTfingers orjthumb. can, engage toaflord lifting exercise there.

for. i j 1 In practice the part of the frame in which" the keys or plates are located is formed tubular with a-longitudinalslot having an enlargement through which the keys are 'in-,- it'roduced, the keys. being made with clamp y n g ts which grip the edges of the slot HARRY os'rnovsxy, or Lennon, ENGLA I,

used by violinistsfor the like. The part b of the bar, frame or stem is made with an aperture 7 midway of its length ,as shown in Fig. 1 in which can slide the other part 0 carrying the rest or support 01 so thatithe position of the latter can be adjusted to the users requirements' The part b is formed tubular as shown, 9 being the longitudinal slot therein, fitting a neck It on the body of the keys so that they can be slid along the said slot, and i being the clamping nuts screwing on to the said body and adapted to grip the edge of the slot 9 and receive the stems j of the pistons of the keys at,

as clearly shown in Fig. 1, in which is the spring beneath the piston 9' The pis ton-stems j may be marked with divisions (not shown) to indicate the pressing power exerted by the fingers. Z is the screw working in the body or bottom of the clamping portion of the key and by turning which the tension of the spring 70 can be adjusted.

m is the additional spring coiled round the piston-stem j andiwhich may be used, or not, asrequired. Instead of the tension of the spring 70 being adjusted by operating the screw Z, the resistance to pressure of the keys canobviously bevaried by removing the springs lo and m and replacing them by others of different strength. qtis the enlargement of the slot 9, through which the keys d are introduced into, or removed from, the tubular part b of'thefibar, frame or stem of the apparatus.

As heretofore stated it is preferable to provide a scale or divisions (not shown) on the tubular part b of the frame to indicate the distance apart to which the keys are moved and secured, and when it is required to stop any one or more of the keys (2!, from being actuated by the fingers in order to develop independence; of action of the other fingers, the springs m and k are; re- 1 moved from such keys so that the pistons thereof will drop and be inoperative. The 1 construction of the modified Figs. 6 and 7 is precisely'the' same as that 'her'einbe'fore; described with. reference to Figs; 1 tot) except that two similar parts I) of the jframe areconnected together, and

V carryfkeys direpresenting the white and black keys, respectively, of'a piano... E is obvious-that, if required, a key a can'be used separately from the rest: of the; apparatus, for exercsi sing ,the fingers by placing the base of the key, (provided-with a thimble 10 havinga rubber pad or disk'as apparatus, for the use of pianists, illustrated, in

mediate its ends, in whichsaid SUPP rt and pressing the piston 7' with the fingers or thumb against the action of the springs.

The device illustrated in Figs. 9 and 10 for affording lifting exercise for the fingers and, thumb V and which I provideupon the bar or stems in proximity to the 'rest' or support 0? consists of a sleeve g which can be slid tofany desired position onthe said bar and then secured in said position by means of a pressure screw 4". The sleeve-g carries a stirrup 8 having attached thereto a 'loop I? of leather or other suitable material, which stirrup can be moved up and downa pin or rod ,u depending from the sleeve 9 againstrthe action of a spring 12 on the said' pin or rod so that, with the hand wrist or fore arm of the user resting on the support d,'any one of the fingers or the-thumb can engage the loop 23 and exercise its lifting power againstthe resistance of the spring which can be varied by unfasteningthe nut wfon the'rod or stem 10 and removing the said springand replacing V the same by another spring of different tension, or. by screwingthe nut up or. down upon the said rod or stem.-
