DRUM.
Specification of Letters Patent. Patented J 1111620, 1922.
Application led February 7, 1922. Serial No. 534,767.
T0 @ZZ whom t may concern.
Be it known that we, VILLTAM H. BALD- WIN and CHARLES T. PLUMMER, citizens of the United States of America, and resi dents, respectively, of Duluth, St. Louis County, Minnesota, have invented certain new and usefuly Improvements in Drums, of which the following is a full and clear speciiication.
Drummers are now accustomed to use a smallv drum for orchestra work and a deeper drum for band work, necessitating their having two ormore drums if they are engaged in both lines of employment. It is the objectV of our invention to provide a drum which., vby atelescopic action, can be made small lto bring the heads closer together for orchestra work or enlarged to increase the distance between the heads for band work, the construction being such that the parts may be clamped together by means accessible from the exterior of the drum body at any point within the range of their adjustable capacity. It will be understood that this invention is applicable to bass drums as well as the smaller types of drums.
In the drawing- Fig. l is a perspective view;
Fig. 2 is a vertical sectional view of a portion of the drum;
Figs. 8 and 4t are views of details hereinafter described.
Referring to the drawing annexed by reference-characters, 5' designates two endsections of the cylindrical body and 6 the intermediate or central section of the body, this latter being slidable into the adjacent ends of the main sections 5 and being iitted nicely against the interior faces thereof. The end-sections 5 are provided with the usual heads 7, and suitable devices are provided for clamping the central section to the end or main sections in their adjusted posi-l tions.
The clamping devices we prefer using consist of two series of set-screws 8 arranged at spaced intervals around the drum, one series being carried by each of the main sections 5, the clamp-screws being located at the inner ends of said main sections 5. The inner threaded ends of these clampscrews extend through longitudinal slots 9 formed in the central section and are tapped through clamp-plates l0 which, when the clampwscrews are tightened, are
drawn hard against the inner face of the central section 6, to thereby clamp the parts in their adjusted positions. These clampplates lO areguided between longitudinal flanges or ways ll fastened to the interior of the face of the central section 6,these iianges l1 serving not only to guide the central section 6 in its movements upon the main sections 5, but also serving to prevent rotation of the clamp-plates l0, thereby enabling said plates `lO to serve as nuts for the clamp-screws. These clamp-plates l0 are long enough to close the portions of the slots 9 which extend beyond the inner edges of the main sections 5 and thus confine the. air in the drum. As shown in Fig. 3, these clamp-plates l0 are dovetailed between theways l1 to thereby prevent undue inward movement of the clamp-plates l0 when the clamp-screws are loosened.
It will be observed that for a small drum the parts may be telescoped suiiiciently to bring the inner edges of the main-sections 5 close together or in contact, and that for a larger drum the sections may be slid apart to the limit of the slots 9. When the parts are thus adjusted to obtain the proper distances between the heads 7, they may be, by the devices illustrated, clamped as rigidly together against loosening or vibration as is the usual non-adjustable drum. The beads 6 fastened to the edges of the central section serve to reinforce the section.
We do not desire to be understood as limiting ourselves to the precise details of construction and arrangement shown, as variations and modifications therefrom may be made without departing from the spirit and scope of our invention and improvements. We therefore reserve the right to all such variations and modifications as properly fall within the scope of our invention and im provements as set forth in the terms of the following claims.
What we claim is:
l. A drum comprising a body made of two Louter sections and a central section telemeans accessible from the exterior tor clamping the parts in each ot their adjusted positions to thereby enable the drum to be converted from a small drum to a large drum and vice versa.
3. A drum comprising a body made of telescoping sections to thereby vary the dis tance between the heads, said body embodying a central section telescoping inside ot the adjacent sections, said central section being provided with longitudinal slots at in,- tervals, clamp-screws carried by the main sections and extending inwardly through said slots, and plates on the inner ends of said cla1np-screWs adapted to clainp against the inner face of the central section.
4f. ifdruin comprising a body made of telescoping sections to thereby vary the distance between the heads, said body embodying a central section telescoping inside ot the adjacent sections, said central section be ing provided With'longitudinal slots at in tervals, clamp-screws carried by the main sections and extending inwardly through said slots, and plates on the inner ends of said clamp-screws adapted to clamp against the inner 'tace otl the central section, said plates being long enough to close the ends of the slots which project beyond the main sections.
5. A drum comprising a body made of teiescoping sections to thereby vary the distance between the heads, said body embodying a central section telescoping inside ot' the adjacent sections, said central section being provided with longitudinal slots atintervals, clamp-screws carried by the main sections and extending inwardly through said slots, and plates on the inner ends of said clamp-screws adapted to clamp against the inner face oit the central section, said plates being long enough to close the ends of the slots which project beyond the main sections, means being provided on the interior of the central section for guiding said central section in its telescopic movements.
In testimony whereof We hereunto atix our signatures this 4th day of February 1922.
