GRANT D. WOOD, OF CHICAGO, ILLINOIS.

CONVERTIBLE TRUMPET AND CORNET.

Application filed April 28, 1915.

T0 aZZ whom it may concern:

Be it known that 1, GRANT D. 001), a citizen of the Jnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Convertible Trumpets and Cornets, of which the following is a specification.

Musicians frequently desire to have both a trumpet and cornet for use on special occasions, and with the instruments as commonly constructed, they must necessarily carry two separate instruments, each of which is relatively large and expensive.

The present invention relates to a musical instrument which may be readily converted from a trumpet into a comet or vice versa. As such instruments are ordinarily constructed, the bells are rigidly secured to the main portion, which contains the action or set of valves, so that if the bell orconnected tube becomes indented it is ditlicult to remove the bell for straightening or fixing the same. It is also more or less ditlicult to again secure it properly in position.

One of the objects of this invention is to provide a musical instrument of this character which is to constructed that the bell and other portions may be readily removed from the action or valve portion for the purpose of repairing the same.

The main object of this invention, however, is to provide an instrument which may be readily converted from a trumpet into a cornet or vice versa; to provide such an instrument which may be simply and economically constructed without interfering with the tone quality; to provide a simple and eflicient fastening device for holding the parts of the instrument together; and to provide such advantages and improvements as will be more fully described in the following specification.

In the accompanying drawings illustrating this invention: Figure 1 is a side view of the instrument arranged as a trumpet, as seen from the bell side, the arrangement for a cornet being shown in dotted lines; Fig. 2 is a plan view of the same; Fig. 3 is a side view of the instrument as seen from the mouth pipe side, the arrangement for a cornet being shown in dotted lines; Fig. 4 is an enlarged sectional view taken on the line 4-4 of Fig. 2; and Fig. 5 is an enlarged detail showing the fastening devices.

As shown in these drawings, 6 indicates Specification of Letters Patent.

Patented Mar. 21,

Serial No. 24,399.

the action or valve containing portion of the instrument, which is utilized when the instrument is to be used as a trumpet, and also as a cornet, the difference between these instruments being that the trumpet has a relatively long bell and nearly straight short mouth pipe, while the cornet has a shorter bell and a longer and usually crooked mouth pipe. This action or valve portion of the instrument is provided with an inlet pipe 7, which is arranged in the usual manner, and which is engaged in a telescopic manner by one branch of a. U-shaped tube 8. The other branch of this tube engages with the inner end of the mouth pipe 9, these being made in the form shown in full lines, when the in strument is to be used as a trumpet. The mouth pipe 9 is provided with two sockets 10 and 11, which are preferably rectangular in cross section. These sockets engage with correspondingly shaped arms or projections 12 and 13, which are secured to the valve cylinders 14. The sockets 10 and 11 are provided with set screws 15 and 16 for engagement with these arms or projections to hold the pipe securely in position. While such fastening means may be varied in construction without departing from the spirit of my invention, yet I found from actual construction that this forms an eificient and rigid arrangement, whereby the mouth pipe may be firmly secured to the action or set of valves. When the instrument is to be changed from a trum pet to a cornet, the tube 8 is removed and the set screws 15 and 16 loosened, so that the mouth pipe may be readily disengaged from the projections 12 and 13. Then a smaller U tube such as indicated at 17 is used to connect up the curved or bent mouth pipe 18, which is provided with sockets adapted to fit over the brackets 12 and 13 in a similar manner, this U tube and mouth pipe being of the form commonly used for a cornet.

The action or set of valves 6 is provided with an outlet pipe 19, which is engaged by the bent inner end of the trumpet bell 20. This bell is provided with sockets 21 and 22, which engage with arms or brackets 23 and 24, extending out from the valve cylinders 14. The sockets are provided with set screws 25 and 26, for holding them in engagement with the arms. By means of this arrangement the bell 20 may be readily disengaged from the main portion of the instrument.

When the instrument is to be converted into a cornet, a shorter bell 27, such as shown in dotted lines in Fig. 1, is used to replace the trumpet bell 20, this shorter bell being provided with correspondingly arranged sockets for engagement with the brackets 23 and 24.

By means of my improved construction it will be seen that by having properly shaped bells and mouth pipes, the instrument may be utilized for either a trumpet or a cornet, the change being easily and quickly made from one instrument to an other. By means of this combination instrument the player will be equipped so that he will have either a trumpet or cornet as desired, and the same can be made more economically than two instruments. Furthermore, if the bell or mouth pipe should be come dented or bent, it may be readily removed and repaired without liability of injury to the rest of the instrument.

Having thus described my invention, which, however, I do not wish to limit to the exact construction or arrangement herein set forth, except as specified in the following claims, what I claim and desire to secure by Letters Patent is:

1. A convertible trumpet and cornet, comprising a main action or set of valves, with interchangeable and detachable mouth pipes and bells, suitable for forming either of said instruments. 7

2. In a musical instrument of the character set forth, the combination with a setof valves forming the main portion of the instrument, of detachable and interchangeable cornet and trumpet mouth pipes and detachable and interchangeable cornet and trumpet bells.

3. In a convertible trumpet and cornet, the combination of a main portion, comprising the valve cylinders, with inlet and outlet pipes, of brackets secured to said cylinders, detachable and interchangeable cornet and trumpet mouth pipes having fastening means for engagement with some of said brackets, and detachable and interchangeable cornet and trumpet bells having means for engaging with others of said brackets.

a. In a convertible trumpet and cornet, the combination with the main portion, comprising the valves and connected parts, of a pair of brackets secured to one side of said main portion, detachable and interchangeable trumpet and cornet mouth pipes having sockets for engagement with said brackets, said sockets being provided with set screws for locking them in position.

5. In a musical instrument of the character set forth, the combination with the valve cylinders, of a pair of brackets ar' ranged longitudinally of the instrument, detachable and interchangeable cornet and trumpet bells having sockets for engagement with said brackets, and set screws for fastening said sockets in engaging position.
