CHARLES J. KIEFER, OF INDIANAPOLIS, INDIANA.
TROMBONE.
Application led January 20, 1913.
Specification of Letters Patent.
Patented Nov. 18,1913.
Serial No. 743,172.
To all whom if may concern Be it known that I, CHARLES J. KIEFER, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Trombone; and I do hereby declare that the following is a full, clear, and exact description thereof, reference be ing had to the accompanying drawings, in which like letters refer to like parts.
The object of this invent-ion is to improve the construction of trombones so as to render the bow connected with the outer casings readily removable for the purpose of keeping the instrument clean.
Heretofore it has been necessary to introduce cleaning material throughout the entire outer casing which is double and each side is more than two feet long so that the total is more than four feet long, and with a sharp intermediate bow. The result is that cleaning the same has been extremely difficult and often the cleaning material gets lodged and is inaccessible and ruins the trombone.
To obviate this difficulty and render the outer casing readily accessible for cleaning and other purposes, is the aim of this invention.
The nature of the invention will be understood from the accompanying drawings and the following description and claims.
In the drawings, Figure 1 is a plan view of the trombone. Fig. 2 is a central longitudinal section through the lower end on a larger scale. Fig. 3 is a section on the line 3 3 of Fig. 2, on a larger scale.
To the main portion of the instrument there are two parallel slides or inner tubes 10 secured and on them operates telescopically what has been termed the outer casing 11 which consists of two long tubes of greater diameter than the slides and united by a bow 12 so as to form one continuous outer casing or tube.
Heretofore the two side sections of the outer casing and the bow have been made integral so that the bow and side sections could not be disassociated. My invention consists in making these three parts separate and having the bow detachably connected with the outer casing.
The connection between these parts is indicated in Fig. 2, where the two ends of the bow have a radial iange 13 over which a coupling 14 extends with an inwardly extending flange at one end and said coupling is internally threaded to engage the externally threaded sleeve 15 which is rigidly secured to the outer end of each of the outer casings. The coupling 111, when tightened, will draw the parts tightly together and make a close joint and yet the parts can be readily separated. The coupling 1d is milled on its external surface so that it can be turned by the lingers very tightly. The outer ends of the outer casings are braced by braces 17 so that they will be maintained in proper positions when the bend 12 is removed. The ends of the slides 10 have stockings 18 on them as usual. The arrangement is such that the bores of the bow and the outer casings 16 are uniform, even at the joint, and when the interior of the instrument is oiled as usual, the oil will close any possible air leakage at the joints, although with this arrangement there should be no air leakage.
I claim as my invention:
1. A trombone including slides, outer casings adapted to telescope on said slides, a bow, and threaded couplings for removably securing the ends of said bow to the outer ends of the outer casings.
2. A trombone including slides, outer casings adapted to telescope on said slides, a sleeve secured around the outer end of each outer casing and which is externally threaded, a bow with an outwardly extending flange at each end, and a coupling with an inward flange to engage the iange on the bow and internally threaded to screw on said sleeve for making a tight but removable joint between the bow and each outer casing.
3. A trombone including slides, outer casings adapted to telescope on said slides, a bow separable from said outer casings, means for removably securing the bow to the outer ends of the outer casings, and a brace connecting the outer ends of the two outer casings near the bow.
In witness whereof, I have hereunto affixed my signature in the presence of the witnesses herein named.
CHARLES J. KIEFER.
