UNETEE STATES WILLIAM F. MQINTOSH, OF BOSTON, MASSACHUSETTS.

SNARE-STBAINER AND EIUFFLER FOR DRUILVZS.

Application filed October 6, 1908.

To all whom it may concern:

Be it known that I, VJILLIAM Moln- Tosn, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful improvement in Snare-Strainers and Mufflers for Drums, of which the following is a specification.

It is frequently necessary, especially when drums make a part of an orchestra or band, to loosen or release the snares in order to stop and prevent vibration and produce the tom-tom efiect, and to tighten them into their normal strained position again.

he object of this invention is to provide a snare-strainer and mufiler in which the snares can be loosened or tightened instantaneously, between two notes, or at givn point or signal, thereby inalr'ng a quick change without adiustment at the time or either of the changes; and the invention consists in the novel construction and arrangement of parts, fully described below, and illustrated in the accompanying dram.- ings, in which- Figure l is a view of the under side of a drum with my device appl'ed thereto and in its normal position, that is, with the snares taut. Fig. 2 is a side view of the device in its normal position, a portion only oi the drum being illustrated. 3 is a section taken on line 33, Fin. 2, the upper portion 01" the plate 1* being shown in elevation or edge view, but the lower portion being shown in section on said 1 ie 3 33, in order to illustrate its connection with the hook s. Fig. i is a section taken on line S 3, Fig. 2, the plate r being showinwholly in elevation or edge view. Fig. 5 is a vertical section taken through the pivot j, looking toward the right.

Similar letters of reference indicate corresponding parts.

Reference letter (t represents the shell of an ordinary drum, 1) the straining-hoop, c the lining-hoop, d the flesh-hoop, and c the headall the parts referred to being at the lower portion or the drum.

f represents the snares, usually constructed of wire or catgut.

All the above parts are constructed substantially as usual.

In my attachment, 9 represents a plate secured at i to the straining-hoop near its lower end. The plate is provided near its lower edge with ears h l oetween which there Specification of Letters Patent.

is pivotally secured at j the horizontal foot 7c of an upwardly extending T-shaped arm I whose upper end at constitutes the lower portion or member of aclamp the upper portion or member 17, of which is secured tightly at 0 against the end portions of the snares f, holding them firmly. A vertical spring p is secured at one end at q to the outer face of the plate g, and its lower end bears against the end of the foot is. A thin bar f is held in swinging engagement with the inner face of the arm Z by means of the downturned hook s, and an adjusting screw 15 extend through the arm Z against said bar 1'. A wire a is pivotally held in eyes 0, the i ral part w of the horizontal portion l thereof being formed up into cam-shape, and said cai 1-wire is provided with a handle to.

l fi'hen the parts are in the position illustrated in Figs. 1 2 and 3, the handle .t is in an approximately vertical position, and the cam portion to of the cam-wire a is extended and bears against the bar r, forcing said bar outward and, of course, swinging the arm Z outward into an approximately vertical position, and thus stretching the snares taut across and close to the drum-head esaid snares extending from between the clamp members in and n through a passage y in the straining-hoop b. New il' it is desired to suddenly loosen the snares so that the tomtom ciiect will be produced, the handle a: is swung quielriy down and the cam portion to oi the wire it is tned down, thus enabling the spring 32 which bears against the feet to quickly swing said foot outward and, of course, the i m inward into the position indicated in i g. 4:. A quick ing of the handle as swings the cam outward and upward past the center into the position illustrated in 1, 2 and 3 and the snares are again strained taut against the drumhead. 'i he screw t is purely an adjusting screw, and it in connection with the thin bar 9" regulates the length of the throw of the arm Z. By means of the hooleconnection s which extends through a suitable hole in the bar r, danger of breakage thereof, which is apt to occur if the bar is igidly connected with the arm Z, is obviated.

Having thus fully described my invention, what I claim, and desire to secure by Letters Extent, is:

1. in a snare-strainer and muffler for drums, a plate adapted to be secured to the l drum, an arm or lever pivotally connected near its lower end to said plate, a spring intermediate of the plate and arm or lever and bearing against the latter below its pivotal connection with the plate, a snare-clamp supported by said plate above said pivotal connection, a cam supported above said pivotal connection between said plate and arm or lever, and means for swinging said cam into and out of engagement with the arm or lever and thus straining and loosening the snares, for the purpose set forth. I

2. In a snare-strainer and mufier for drums, a plate adapted to be secured to the drum, an arm or lever pivotally connected near its lower end to said plate, a spring intermediate of the plate and arm or lever and bearing against the latter below its pivotal connection with the plate, a snare-clamp supported by said plate above said pivotal connection, a cam supported between said 20 plate and arm or lever, a thin bar loosely connected at its lower end to the inner surface of the arm or lever and extending up said surface in the path of rotation of the cam, an adjusting screw extending through 2
