VIRGIL MONROE GRIFFIN, OF DENVER, COLORADO.
MUSICIANS FlNGER-STRENGTHEN ER.
SPECIFICATION forming part of Letters Patent No. 638,632, dated December 5, 1899.
Application filed March 10. 1899.
To all whom it may concern.-
Be it known that I, VIRGIL MONROE GRIF- FIN, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Musicians Finger-Strengtheners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures and letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in finger-strengtheners for use by musicians and students of music. Its object is to increase the strength of the joints of the fingers, wrist, and arm, and also to develop the muscles brought into requisition when performing on the piano, organ, violin, or other instruments requiring special finger exercises or practice.
My object is to provide an apparatus of this class which shall be simple in construction, economical in cost, reliable, durable, and efficient in use; and to these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which isillustrated an embodiment thereof.
In the drawings, Figure 1 is a vertical section taken through my improved apparatus on the line XX, Fig. 2. Fig. 2 is a front view of the device. Fig. 3 is a fragmentary front View of the fin ger-strengthening device,shown in detail and on a larger scale. Fig. 4 is a side View of the same with the fingers in place. Fig. 5 illustrates one of the tension-pegs with which the yielding or elastic support for the finger-rings is connected.
Similar reference characters indicating corresponding parts in the views, let the numeral 5 designate the bottom, 6 the back, and 7 the sides, of a cabinet or case provided with a top 8, hinged to the back at 9, a front 10, hinged to the bottom at 12 and composed of two parts 10 and 10, hinged together at 13. By means of this hinged front the cabinet may be completely closed, concealing the operating parts of the mechanism. The front Serial No. 708,537. lNo model.
I when open, as shown in Fig. 1, maybe employed as a writing-desk. As shown in the drawings, (see Fig. 2,) the cabinet is provided with an additional side piece 7, between which and the adjacent side 7 are located shelves or horizontal partitions 7, forming pigeonholes. In the upper part of this cabinet is located a board or plate 14, hinged to the sides 7 at 1.5 and supported by a rod 1b, whose upper extremity is connected with a staple 17, attached to the central front portion of the board, while the lower extremity of the rod engages a toothed rack or ratchet 18, attached to the lower portion of the back of the cabinet on the inside. In suitable openings formed in the board 14 are inserted tension-pegs 19, similar to those employed in connection with the strings of a violin. Attached to each peg 15) is a an elastic band 2i, whose opposite extremity is connected with a stirrup 22, upon which is hung a ring 23, to which is attached a rearwardly-depressed stop-plate 24, which limits the entrance of the finger, allowing only the tip to pass through the ring, which is specially intended for use in exercising the first joint of the finger. Another ring 25 is con nected with the ring 23 by means of a loop 26. Passed through the stop 2a is a cord 27, whose lower extremities are attached to the rear edge of a board or plate 28, located in the lower part of the cabinet, and hinged near its forward edge, as shown at 29. This board 28 is held in any desired position of adjustment by means of dogs 30, whose upper extremities are pivoted to the sides of the cabinet. The lower extremities of these dogs are sharp, whereby they are adapted to enter the wood board and maintain it in position.
Anydesired number of strengthening-rings 23 and 25 and their attachments may be employed. In Fig. 2 aseries of ten is shown, permitting the simultaneous exercising of the thumbs and all the fingers of both hands, if desired. There is a peg 19, an elastic band 21, and a cord 27 for each pair of rings 23 25. The pegs are arranged in a row upon the upper hinged board 14, and the cords 27 are all secured to the lower hinged board 28. Though elastic bands are described herein, it is evicord or wire loop 20, through which is passed I dent that coil or other springs or other suitable yielding devices maybe employed. The tension of the bands 21 may be regulated individually, or one at a time, by turning their respective pegs If). The tension of all the bands may be regulated without materially changing the elevation of the rings by adjusting the board 14 through the instrumentality of the rod 16 and the ratchet lb. Again, the tension of these bands may be regulated by the adjustment of the board 28; but this adjustment changes the elevation of the rings, since as the board is raised the recoil of the bands lifts the rings, and as this board is de pressed the rings are drawn down. This explanation is based on the assumption that the cords 27 are non-elastie, which is preferably the case. A transverse elastic cord or string 31 is passed in 'front of the cords 27 a short distance below the rings, its extremities being attached to the sides 7 of the cabinet- This elastic cord limits the forward move. ment of the non-elastic cords and has a tendency to maintain the rings in their proper position.
The sides 7 of the cabinetare provided with a series of grooved ways B, adapted to receive tongues C, formed on a keyboard D, which forms a hand-rest, and may be employed in connection with the rings for exercising the fingers.
The use of the device is illustrated to some extent in Fig. t. When it is desired to exercise the first joint of the finger, the ring 23 is employed, since the tip only of the finger can pass into the ring. Then by working the first joint the tip of the finger is moved downwardly, stretching the elastic band. As the tip of the finger is raised in working the joint the recoil of the band raises the ring accordingly. It is evident that these exercises will strengthen the first joint of the finger. IVhen strengthening the other joints of the finger, the ring 25 is employed, since it allows the finger to slip through the ring as far as desired. To exercise the second joint, the finger should engage the ring 25 at the first joint. The second joint should then be moved in the same manner as heretofore explained with reference to the first-joint exercises. To exercise thelmuckle-joint,tl1e second joint should engage the ring as, shown in Fig. 4-. To exercise the wrist and elbow joints, the finger or fingers may be slipped through the rings as far as they will go, after which the joint it is desired to strengthen is worked, while the intermediate joints, if any, are kept rigid. The shoulder-joint may be strengthened by a whole-arm movement. \Vhen the fingers are passed through the rings, they may be employed to operate the spring-supported keys of the keyboard D, which may be located at any elevation required to produce the best results.
Having thus described my invention, what I claim is 1. In a finger-strengthenin g device, the combination of a yieldingly-sns ended ring, and a cord leading downwardly therefrom and having its lower extremity secured in place.
