Application filed June 3,1907. erial No. 377,019.
To all whom ii. may concern:
lle it known that I, Atrnoxs K'mznx, a citizen of th United States of America, residing at Coburg, and whose p iddress is No. 16 Marlit, Coburg in the Empire of Germany, have invented new and usel'ul Apparatus tor Iland Gymnastic Exercise, 01' which the l'ollowing is a specification.
The present invention relates to a device which is adapted for use in hand gymnastic exercises and which is especially intended to exercise the actions of the separate fingers ol the hand independently from one another, to remove muscular stillness and spasm and to improve the independent action of one finger from the others, as such qualities are especially needl'ul for pianol'ortc playing, violin playing, skilled manual arts and l'ortypcwriting and the like.
The present device is adapted to hold the finger or fingers completely out of action and motionless in any desired position whereby the exercise ol the finger or fingers which are not held out of action is facilitated and the independent action of one finger l'rom another is exercised.
For this purpose the device consists oi mechanical parts adapted to hold the separate fingers rigidly and capable ol being adjusted to correspond to the special finger lengths of a hand while laterally capa blc oi being moved together or apart so as to allow oi two lingers being spread apart any desired distance.
My invention illustrated in the accompanying drawings, in. which:
Figure 1 shows a plan view oi the apparatus, and Fig. 2 shows a side view. I
lel'erring now to the drawings, the device consists of a strap a which is adapted to be fastened around the wrist. This strap is attached to a metal plate I) to which aseries of rods corresponding with the four.
fingers are connected by sleeves cl. These sleeves are pivoted by pivots i to the back of the plate, as shown in the drawings, in such a manner as will allow of the arms 9 being brought together or spread apart. The said arms ,1 carry at their ends loopsf which are adapted to be passed over the ends of the fingers. The arms g can be adjusted in the sleeves (Z to the lengths of the particular lingers over which their respective loops f have been passrd. These arms are clamped in position by means of screws. The front edge 72 ol the plate I) is bent up, as shown. in Fig. 2, and provided with a number of serrations between which the said sleeves (l are adapted to engage, as shown.
It will be obvious that by this apparatus I can for instance, pass the loops f of three of said arms g over l l l the first, third and fourth fingers of a hand and spread the fingers laterally any desired distance apart by moving the pivoted sleeves d of said arms over the serratcd edge h to the desired positions while I leave the second finger lree to move. In this manner I am enabled to exercise a particular linger independently oi? the other lingers and at the same time exercise the spreading apart of said fingers.
The sleeves or holders (Z can be made oi any suitable material and can be pivoted upon the plate in any convenient position, not necessarily in the position shown; or instead ol' being pivoted said sleeves can be elastically secured to the plate. In the same manner the .rods which hold the fingers i'ast may be made of any material and of any convenient form and length and can be provided instead of loops with end caps or the like in order to give the necessary finger hold. These rods can also be attached directly to the plate instead of being connected to said plate through the slots d. I can also arrange a single rod attached to the plate adapted to branch into four arms corresponding to the lingers which are sul'licicntly elastic to allow 01' said arms being moved laterally over the rack and such l'astening device would have to be made adjustable. The plate itscll can be of any convenient material and may be strengthened in any convenient manner. This plate need not necessarily be fastened to the hand by the wrist but if desired maybe iastened around the palm or in any other suitable position.
It will be obvious that the apparatus described will serve for developing the independence, strength and flexibility ol the separate fingers and their power of spreading apart.
What I claim is:
1. in a device for hand gymnastics, the combination of a plate, means for attaching the plate to the hand, a series of slei corresponding with the lingers oi? the hand pi" ol'ed to said plate. a, eries oi" arms adapted to engage in and to he clamped to said sleeves, means for holding the lingers to said arms and means [or holding said sleeves in the desired positions on said plate, substantially as described.
2. In a device for hand gymnastics. the combination of for attaching the plate to the hand, a. series corresponding with the fingers ol' the hand pi\= oted to said plate. a series of arms adapted to engage in and to be clamped to said sleeves. loops arranged at the end of said arms adapted to be passed over the fingers and means for holding said sleeves in the desired positions on said plate. substantially as described.
Ii. In a device ifor hand gymnastics, the combination of a plate. means for a l'taehing the plate to the hand, a series of sleeves corresponding with the fingers 01 the hand pivoted to said plate, a series of arms adapted to engage in and to be clamped to said sleeves, loops arranged at the end of said arms adapted to be passed over the fingers and a bent up serrated edge on said plate adapted to hold the sleeves in any desired position on said plate, substantially as described.
4. In a device for hand gymnastics, the combination of a plate, a strap adapted to buckle the plate to the wrist, a series of sleeves corresponding with the fingers 01" the hand pivoted to said plate, a series of arms adapted to engage 10 in and to be clamped to said sleeves, loops arranged at the end of said arms adapted to be passed over the fingers and a bent up serrated edge on said plate adapted to hold the sleeves in any desired position on said plate, substantially as described.
In testimony whereof I have signed my name to this 15 specification in the presence of two subscribing witnesses.
