TROMBONE ATTACHMENT.

Application filed February 18,: 1924. Serial No. 693,422.

My invention relates to slide trombones, and the particular object of the invention is to provide a novel and improved attachment for balancing the instrument when in use.

Another object of the invention is the provision of a device of the character described which may readily be attached to or removed from a slide trombone. Other objects of my invention are'mentioned and described herein. H 7

An embodiment of my invention is illustrated in the accompanying drawing in which Figure 1 is a side elevational view of a slide trombone carrying my invention; Fig. 2 is an enlarged fragmental view of the invention and a cross element of the trombone to which the invention is attached; and Fig. 3 is a section taken on the line 33 of Fig. 2.

Similar numerals of reference indicatelike parts throughout the several views on the drawing.

Referring to the drawing 1n detall, a SllCle "trombone of conventional design is illus trated in Figure 1 thereof, in which the numeral 2 indicates the bell section, 3 a section of the main pipe, and 4: the playing slide reciprocally mounted in the instrument and provided with one or more cross bars 5,-

5 adapted to be grasped by the player, as is well known in the art.

The structure illustrated in Fig. 1 of the drawing, .withoutmy invention applied thereto, is a poorly balanced instrument, the major portion of the weight thereof being carried in the bell section 2 and slide 1 which throws a heavy strain upon the players hand which supports the instrument.

To relieve the players hand, usually the left, of the strain referred to, I provide a counter balance 6 adapted to be removably mounted upon the cross bar 7 which is positioned adjacent the bend section 8 of the' instrument.- The counter balance 6 is a flat annular element and comprises two flat annular half sections 9 and 1.0, respectively, the former being provided with a central annular socket 11 adapted to be engaged by the central annular boss element 12 projecting from the section 10, the two half sections 9 and 10 being detachably secured together by a plurality of headed screws 13. I The head'of each screw may be seated in a recess '14 formed in counterbalance section 9 to bring it fiush with the surface of the latter.

The numeral indicates a bore formed radiallythrough the counter-balance, said bore being divided longitudinally thereof by the-joint between the two sections 9 and 10, and is adapted to to be engaged by the cylindricalbar" 7 upon which it may be clamped removably by the screws 13. The comple-' mentary engagement of the'socket 11 and boss 12 is very advantageous to enable ready. engagement of the screws 13 withthe screw holesin element 10, and also to, prevent lateral deflection of either half section of the counter-balance, wherebythe joint between the two sections is rendered almost, 'if not wholly, invisible, and whereby the two sections of the bore 15 areautomatically brought into accurateregistration. I

. I claim 1. The combination with a trombone, of a counterbalance therefor, said counterbalance 2. The combination with a trombone, of a counterbalance therefor, said counterbalance being split in halves and providedwith a bore which is divided longitudinally thereof by the joint between the two counterbalance sections; a complementary. boss and socket connection between said counterbalance half sections; and means for clamping a trombone element within said counterbalance bore, said means serving-also to detachably fasten the together. I i

In witness whereof I have hereunto afiiXed my signature this 15th day of February, 1924:, at Elkhart, Indiana. v

EDWARD D. COE.
