TRUMPET.

.Applicationv filed November 30, 1927.

My invention pertains to a trumpet and has to do with the manner of the flow of air through the various valves of the trumpet.

An object of my invention in a trumpet is to pass the air directly from the mouthpiece into the first valve so that this valve secures the first dash of air. It is in the first valve that about two-thirds of the playlO ing of a trumpet done, and it is desirable to pass the air through the first valve. before it passes to the second and the third. It has been the prior practice in constructing trumpets to pass the air to the third valve first, and then through the second and first.

Another object of my invention is to give a proper balance to the trumpet in the mounting of the tube leading from the mouthpiece and to the bell on opposite sides of the valves, so that the trumpet does not tend to droop to one side but is easily maintained in correct playing position.

The various features of improvement of my invention above mentioned, and other de- 5 tails, will be apparent from the following description and drawings, in which:

Figure 1 is a side elevation of the trumpet.

Fig. 2 is a side elevation from the opposite direction.

Fig. 3 is a vertical cross section on the line 3-3 of Fig. 1 in the direction of the arrows, omitting the distant parts of the trumpet.

The first, second and third valves are designated 11, 12 and 13, respectively, as is the common designation `in the art, although strictly speaking these designate-the chambers in which the valves are located. The valves are operated by the usual keys 14. The air is led from the mouthpiece 15 through a first air pipe 16, which has a straight passage on one side of the valves followed by a return bend 17; then a forward extending section 18, a front return bend 19, and a rearwardly extending connection 20 to the front valve at the position indicated at 21.

There is an air passage 22 between the first valve 11 and the second valve 12, and a connection 23 between the second valve 12 and the third valve 13. The outlet from the third valve is carried by the rearwardly extending pipe 24, which has a return bend 25, a forwardly extending straight section 26, a forward return bend 27, then a rear- Cil Serial No. 236,683.

ward straight section 28 terminating in the bell 29.

.The trumpet is provided with a U--shaped pipe 30 connected to two positions of the third valve 13; a second U-shaped pipe 31 connecting two positions of the second valve 12, and a third U-shaped pipe 32 connecting two positions of the first valve 11.

From the above construction it will be noted that the air pipe 16 direct from the mouthpiece passes on one side of the assembly of valves, and that the pipe 28 connecting to the bell is on the opposite side of the valve assembly, these two pipes being on approximately the same elevation. The pipe 18 leading from the mouthpiece is on the same side of the valve assembly as the pipe 16, but adjacent the base of such valves, and the pipe 26 leading from the third valve to the bell is on the opposite side of the valve assembly from the pipe 18, the pipe 26 and the pipe 18 being on approximately the same level.

The U-shaped

pipes

30 and 32 extend respectively rearwardly and forwardly from the third valve 13 and the first valve 11, and are in such position that they do not unbalance the trumpet when held in the hand. The U-shaped pipe 31 from the center valve 12 is insufficient to disturb the balance. It will thus be seen that the various tubes leading from the mouthpiece to the first valve are equally placed relative to the tubes from the third valve to the bell, andy that these evenly balance each other and allow the trumpet to be held in the hand without the strain of endeavoring to balance this.

It will be seen from my construction that the air pipe from the mouthpiece, comprising the

elements

16, 17, 18, 19 and 20, give a long air passage with `easy curves, and that the air pipes from the third valve, comprising the

elements

24, 25, 26, 27 and 28, to the bell, also have easy curves and pro- Vide a long air column. This gives my trumpet an excellent quality of tone as well as allowing easy manipulation of the valves in playing the instrument.

Various changes may be made in the principles of my invention without departing from the spirit thereof, as set forth in the description, drawings and claims.

I claim:

1. A trumpet having in combination three parallel valves with keys at the top, a pipe leading from a mouthpiece passing across said valves on one side adjacent the top, said pipe having a return bend, the return portion passing across said valves on the same side adjacent the bottom and having a return bend leading to the iirst valve, a connection from the first to the second and from the second to the third valves, a pipe leading from the third valve and having aV first return bend with a straight portion leading forwardly across the valves adjacent the bottom on the side opposite the pipe from the mouthpiece, said pipe from the third valve having a forward bend and a straight sec* tio-n leading across the valves adjacent their top on the same side as the lower straight portion from the third valve, said upper pipe leading to the bell.

2. A trumpet having in combination a plurality of parallel valves, a pipe leading roin the mouthpiece and having return Melibea bends and being connected to one ot sait valves, a pipe leading from another ot said valves and connected to the bell, the said pipes from the mouthpiece and to the bell being evenly Vbalanced on opposite sides of the valves.

3. A trumpet having in combination three parallel vertical valves, a horizontal pipe from a mouthpiece having a loop on one side of'said valves and being connected to the lirst valve, the loop being on one side ot said valves, a pipe connected to the bell and having a loop on the other side 'of said valves and being connected to the third valve, the said loops evenly balancing each other on opposite sides ot the said vaives and a con necticn from the first to the second and the second to the third valves.

In testimony whereof have signed my name to this specification.Y
