- MOTOR-SUPPORT FOR MUSICAL- INSTRUMENT IBIELLOWS.

Patented Nov. 30, 1915.

Application filed Kay 13, 1914. Serial No. 838,188.

To all whom it may concern.-

Be it known that I, MELVILLE CLARK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Motor-Supports for Musical-Instrument Bellows, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved construction of the support for an electric motor of an automatic player.

It consists in the elements and features of construction shown and described as indicated'in the claims.

In the drawings :-l igure 1 is a front elevation of a portion of an upright piano case containing the mechanism embodying this invention, the front board of the case being removed for disclosing said mechanism. Fig. 2 is a front elevation of the motor sup port on a larger scale than Fig. 1. Fig.3

'is a side elevation of the same.

The drawings show an electric motor, 1, conventionally represented m'outhne only, for operating the bellows and other powerdrivenelements of the automatic player.

tending in opposite directions from the top of the motor body. These arms are bolted to the under sides of two arallel bars, 3, 3,

which ,are each suspen ed by two coil springs 4, 4, from the top bar, 5, of the main supporting frame whose standards, 6, are widespread to admit the motor between them, and extend to the base plank, 7, of the motor sup ort in which the structure is mounted. A ditional coil springs, 8, are stretched fromthe ends of the bars, 3, preferably obliquely outward to the base plank, 7. The bars, 3, 3, are thus held between oppositely stretched s rings and are thereby elastically positione for movement in every direction; and the motor suspended from these bars is thus elastically held, and any vibration which arises from its own action is absorbed by the springs and preventcd'from causing sound-producing vibration in the piano case or mechanism. In order that notwithstanding its elastic support, the motor may have its shaft, 9, and driving pulley definitely positioned for the work to be done, brackets, l1 and 19., are mounted upon the base plank, 7, and extended up past the opposite ends of the motor casing and faced with felt cushions, 11* and 12, which bear against the ends of the motor casing and prevent its tipping or swinging endwisc under the pull of the power-transmitting belt, 13. The springs, 4, 4, and 8, 8, are provided with strips, lfiand 8, of felt or the like intcrlaced with the coils of the springs to prevent or dcadcn the molecular vibration which is liable to cause the springs under tension to give out a squcaking sound, resulting from the slight movement which may occur at their pivotal connection.

I claim 1. A motor support comprising a standard having upper and lower cross members, two parallel bars and-springs by which they are suspended from the upper cross member of the standard, and two springs stretched from each of the parallel bars to the base member of the standard, the standard supports and the last-mentioned springs being suitably spread for admitting the motor between-them, and the bars being adapted to h'ave'the motor suspended from them between said springs and uprights.

2. In combination with a motor standard having upper and lower cross members, two horizontal bars positioned intermediate said upper and lower standard members; two springs from each bar extending to the upper cross member; two springs from each bar extending to the lower cross member of the standard, the latter springs being spread to admit the motor between them, and the motor having at its upper side means by which it is secured to the lower sides of the horizontal bars; guards upstanding from the lower cross member of the standard beyond the ends of the motor, and nonvibratory cushions on said guards for bearing against the motor ends to check its endwise move-' ment.

3. A motor support comprising a standard and coiled springs stretched from the a motor to the standard for elastically sustaining the motor and felt strips interlaced of May, 1914.
