IMPROVEMENT IN MUSICAL WIND INSTRUMENTS.
Specification forming part of Letters Patent No. 140,069, dated J une 17, 1873 application led April 9, 1873.
To all whom 'it may concern:
Be it known that I, GEORGE E. PARKER, of Newark, in the county ofEsseK and State of New Jersey, have invented an Improvement in the Valve-Cylindersof Wind Instruments played with the mouth, of which the following is a specification:
This invention relates to the means for fastening the covers to the valve-cylinders. It consists in a combination, with the notch in the edge of the cylinder, of a screw in the rim or edge of its cover, whereby not only is the latter prevented from turning, but moreover is secured in place simply by the head ofthe screw champing the edge of the cylinder between it and the cover. Great facility is thus afforded for attaching the cover, and its construction is much simpliied; inasmuch as by it the usual screwthread on the outer end of the cylinder and independent ring arranged to it thereon are dispensed with.
In the drawing, Figure l is a central section of the valve-cylinder of a horn, with the cover secured according to my invention, taken axially through the valve, and Fig. 2 is a partly sectional end view thereof.
Similar letters ofreference indicate correspondin g parts in both figures.
AA represents one ofthe valve-cylinders of a horn or other wind instrument played with the mouth. The pipes or tubes a c represent the body of the horn, and the parallel pipes b b represent the pipe into which the current of' air is diverted by the operation of the valve. The valve B is of the usual form, cylin drie, with parallel transverse grooves cut in opposite sides. It may be so turned as to close the branch pipes b b, and establish communication directly through from one to the other of the branches a c of the horn proper; or it may be turned to establish communication between the branches a a and the pipes b b, thereby to divert the current of air from its direct course.
The cover G of the valve-cylinder consists simply of a circular plate, having in its lower edge an annular rabbet, forming a boss which lits Within the mouth of the cylinder. A screw, s, is inserted in this boss, and when the cover is in place the shank of said screw lits in a notch, n, in the edge of the cylinder provided for its reception. Its head projects Outside the cylinder, and, on the screw being screwed up tight, clamps the edge of the cylinder between it and the boss of the cover, and thus firmly secures it in place. lhe usual stops e e are provided on the cover to arrest the movement of the valve at the yproper points.
Heretofore the covers of these cylinders have been usually secured in place by an independent ring screwed over them onto the edge of the cylinders. This has been expensive, and the covers could not be secured with that readiness which is desirable. By my invention the cost of making the cylinders is reduced, and their covers have only to be adjusted into place, and a sin gle turn of the screws will serve to secure them.
What I claim as my invention is The combination, with the notched edge of the cylinder A, of the cover C, constructed as described, and the screw s, substantially as and for the purpose herein set forth.
