COMPLETE SPECIFICATION.
Improvements in Violin Bows.
I PERCY CHARLES NELSON, of Ouray in the County of Ouray and State of
Colorado, U.S.A. a Stadent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to improvements in bows used in playing violins and similar
stringed instruments.
The objects of my invention are,
First, To provide a violin bow in which the hairs may easily be detachable for
repair, or exchanged for a set of new hairs;
Second, To provide a violin bow in which several sets of hairs in succession may
be firmly but detachably secured;
Third, To furnish the hairs for a violin bow in ready-made sets as a market
article, ready to be detachably fixed to the bow.
I attain these objects by the novel construction and arrangement of parts
illustrated in the accompanying drawing in which,
Figure 1, is a central sectional side elevation of my improved violin bow,
Fig. 2, is an enlarged face view of the head of the bow, with the hairs
omitted.
Fig. 3, is an enlarged face view of the frog of the bow, also with the hairs
omitted.
Fig. 4, is an enlarged partly sectional side view of the front portion of the bow.
Referring to the various parts in the drawing by reference letters, A, designates
the bow of which B, is the head, C, the frog and D, the hairs.
The frog C, is adjustably secured to the bow by the screws E, and F, in the old
and well-known manner. In the front sides or faces of the head B, and the frog C,
I provide the cavities or pockets G, and H, respectively, which are preferably
cylindrical. In these pockets I insert the two externally cylindrical sockets I,
and J, which are provided with central openings K, through which the hairs are
inserted and secured by tying their ends into a knot as L, or in any other suitable
manner. The sockets I, and J, are detachably held in the pockets by being each
provided with a notch as M, in which engages the inner end N, of a locking
slide O, which is slidingly inserted in a groove P, in the wood work and retained
therein by the face plates Q, of the head and the frog. The ends of the locking
slides O, are formed with hooks S, and T, of which the outer hooks S, serve as
thumb catches for operating the slide, while the inner hocks T, engage the coil
springs U, lodged in cavities in the wood work and tending at all times to hold
the slides in engagement with the notches in the sides of the sockets. The
sockets I, and J, may be made solid as in Fig. 3, with only a slot or elongated
hole for the insertion of the hair, or they may be as in Fig. 2, made of a piece of
tubing, the hairs placed in the middle thereof and wedged in by D-shaped wedges
as V V. In operation the hairs are arranged in sets and secured with their ends
in the sockets I, and J, so when it is desired to exchange, repair or replace the
hairs with new ones the operator simply pulls on the hooks S, of the locking slides,
until the sockets are released and drop out, when he in similar manner inserts the
sockets of the uext set of hairs.

page_text: Having now particularly described and ascertained the nature of iny said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a violin bow the combination with the bow A, having its head and frog
provided with the pockets G, and H, and the spring actuated slides O, with the
thumb catches S, and their inner ends extending inward through the walls of the
pockets, of the hairs D, prearranged in sets and having secured upon the ends of
each set sockets as I, and J, adapted to fit in the pockets and having external side
notches for engaging the ends of the locking slides, substantially as shown and
described and for the purpose set forth.
2. In a violin bow the combination with the bow A, having its head and frog
provided with the pockets G, and H, and the spring actuated slides O, with the
thumb catches S, and their inner ends extending inward through the walls of the
pockets, of the hairs D, prearranged in sets and having secured upon the ends of
each set sockets as I, and J, adapted to fit in the pockets and having external side
notches for engaging the ends of the locking slides, said pockets and sockets being
-cylindrical, so as to simplify the manufacture of the parts, substantially as set
forth.
