WILLIAM C. REID, OF ELKHART, INDIANA, ASSIGNOR 'IO ELKI-IART MUSICAL INSTRU- MENT COMPANY, OF ELKI-IART, INDIANA, A CORPORATION OF INDIANA.

VALVE FOR WIND MUSICAL INSTRUMENTS.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed November 20, 1911. Serial No. 661,301.

To all whom it may concern:

Be it known that I, WILLIAM C. REID, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Valves for Find Musical Instruments, of which the following is a specification.

In wind musical instruments, as for instance a eornct, the valve spring is generally incased in a barrel with two or more slots, with a plate extending through said slots on which the spring is anchored. This plate frequently becomes tilted, thus throwing the valve out of action.

The object of my invention is to obviate thes and other objections in the valve construction of wind musical instruments by producing a simpler construction which is more effective than the construction now minor objects in view, my invention consists of the parts and combination of parts as will be hereinafter more fully set forth.

In order that I may illustrate my inven tion on a large scale, I will confine the illustrations to a single key valve, but, of course, it will be understood that the invention is applied to all of the key valves of the instruinent.

In the drawing :-Figure 1 is a side elevation of a finger key valve casing of a eornet; Fig. 2 is a vertical central section of the same; Fig. 3 is a section on the line 38, Fig. 2; Fig. 1 is a transverse section of the valve stem; Fig. 5 is a top plan view of the disk, and Fig. 6 is a detail sectional view of another embodiment of my invention. Fig. 7 is a group figure showing three modifications.

1 represents a valve casing of any desired construction, having the usual port openings 2.

8 and 1 are recesses formed in the casing constituting seats to be hereinafter referred to. These seats are of diiferent sizes for a purpose to be hereinafter referred to.

The valve 5 is provided with the usual ports adapted to register with the ports of the casing, said valve having a stem 6 provided with the usual finger top 7. This stem (3 is provided with longitudinal grooves 7", which extend, preferably, from the juncture of the stem and valve to the fixed washer 8.

9 is the securing cap mounted on the stem between the fixed washer 8 and the finger top, said cap adapted to have a. screwthreaded engagement with the top of the casing in the usual well-known manner, whereby the valve is held in the casing.

10 is a disk having a central opening, through which the valve stem is adapted to pass, whereby the disk is slidably mounted on said stem. The disk is provided with lugs 11 constructed to project into the grooves 7 of the valve stem with which they have a neat sliding fit. lVith the lugs 11 in the grooves 7, the disk and valve stem are locked against relative rotation, but at the same time the valve stem is free to slide through the disk. This disk is also provided with lugs 12 extending from its perimeter, preferably diametrically opposite each other. It will be seen in the drawing that one of these lugs is larger than the other and the reason for this is that the valve must be placed in its casing, so that the larger lug will be seated in the larger seat and the smaller lug in the smaller seat in the casing, thereby insuring the accurate positioning of the piston valve in its casing, so that the ports in the piston valve will have proper register with the ports in the casing.

13 is a coil spring arranged around the valve stem, one end of which is seated in a groove 14 in the disk 10, while the other end is seated within a collar 15 on the under face of the fixed washer 8.

The piston valve 5 is inserted in its casing and the lugs 12 seated in their respective seats, whereupon the valve may be secured in the casing by means of the usual threaded cap 9, whereupon the valve is free to be manipulated by the fingers in the usual manner, but is held against rotation by reason of the lugs 12 in the seats formed in the casing and the lugs 11 in engagement with the longitudinal slots or grooves 7 whereby the disk has a free sliding engagement with the valve stem but is locked on the stem against relative rotation with the stem and at the same time the disk is locked against relative rotation by reason of its lugs 12 being seated in the seats in the casing.

As a result of my invention, I am enabled to construct a Valve action with a smaller coil spring than that heretofore used and eliminate the necessity of the usual slot-ted spring barrel. I find that by my invention, I get a much more accurate action of the valves and at the same time the action is more reliable, lighter and quicker than that of the usual valve.

It is of course obvious, as shown in Fig. 6, that the disk may be provided with the slots 16 and that the valve stem may be pro vided with ribs 17 to engage said slots, which is an equivalent construction of the lugs 7 and the slots 11, shown in the other figures ot' the drawing.

As shown in Fig. 7 the valve stem A may be hexagonal, square or triangular. In fact it may be of any non-rotating locking shape in cross section, and the opening for the stem through disk B is shaped to correspend with the shape of the valve stem.

I claim 2 1. In a wind musical instrument, the combination with the valve, its casing, a. stem for said valve, of a disk mounted on said stem and having a sliding non-rotating engagement therewith, and lugs projecting from said disk and interlocking with said casing against rotation, whereby the valve is free to reciprocate, but is locked against rotation in its casing.

2, In a wind musical instrument, the combination with the valve and its casing, of a stem for said valve having longitudinal grooves in its periphery, a disk slidably mounted on said stem, lugs projecting from said disk into the grooves of the stem thereby locking the stem and disk against relative rotation, and lugs projecting from the perimeter of said disk and having locking engagement with said casing, whereby the disk is locked in said casing against rotation.

3. In a wind musical instrument, the conr bination with the valve and its casing, of a stem for said valve provided with a head and having longitudinal grooves in its periphery, a disk slidably mounted on said stem, lugs projecting from said disks into the grooves of the stem, thereby locking the stem and disk against relative rotation, but leaving them free to slide relatively, and lugs projecting from the perimeter of said disk and having locking engagement. with said casing, whereby the disk is locked in said casing against rotation, and a coil spring around. said stem, one end of which is seated on said disk and the other end seated under said head.

1. In a wind musical instrument, the combination with the valve and its casing, seats in said casing of different sizes, of a stem for said valve having longitudinal grooves in its periphery, a head on said stem, a disk slidably mounted on said stem, lugs projecting from said. disk into the grooves of the stem, thereby locking the stem and disk against relative rotation, and different sizes of lugs projecting from the perimeter of said disk adapted to be seated in the corresponding sizes of seats in the casing, whereby the disk is looked in said casing against rotation.

The foregoing specification signed at Elkhart, Indiana, this 24 day of October, 1911.
