TRUMPET Specification of Letters Patent.

Patented June 11,1912.

Application filed'llarch 11, 1910. Serial No. 548,667.

To all whom it may concern:

Be it known that I, Josnrn MAReULIn's Laxnox, a subject of the King of England,

residing at 20 Central Hill, Upper Norwood, in the county of London, England,'

have invented certain new and useful Improvements 1n Trumpets, and do hereby declare the following to be a full. clear, and

extremely cumbersome when it is requiredto transport the machine from place to place. Various machines have already been devised fitted in cabinets, with a sound conduit located in the cabinet, but it is found that the reproduction from a machine of this type is not-so satisfactory as when the ordinary-trumpet or horn is used owing to the restricted dimensions of the trumpet and tot-he lack of a proper bell portion.

My present invention refers to a method of constructing a trumpet either alone or in connection with the cabinet containing the talking machine in such a way that the whole trumpet or the bell portion can be folded into a very small compass and yet when opened a full-sized trumpet or one of any required dimensions is formed.

it. will be understood that in carrying out my invention anypolygonal arrangementmay be employed and the invention is not limited in this respect nor to the exact de- -tails shown and described; still for the pur-.

pose of disclosure, reference is bad to the accompanying drawings illustrating practical embodiments of same and to the following description referring, for simplicity only, to an octagonal apcrture'with a corresponding number of trumpet sections, but it will. be understood that the following disclosure is merely by way of example and the construct-halal form may be varied largely to suit the requirements of special cases. without departing from the spirit of the invention.

In order that my said invention may be more clearly understood, IWill now proseed to describe by way of example varlous methods, of carrying'out the same by malt-- ing either the bell portion or the whole trumpet from a number of sect-ions capable the flaps together. Fig. 4 is a diagrammatic View showing a device such as that illustrated at Figs. 1 and 2 attached to the front of the cabinet of the talking machine. Fig. 5 shows awhole trumpetbuilt up from hinged flaps.

Referring to the method of carrying out the invention shown at Fi s. 1 to 3, a is a square board or frameworz having an 00- tagonal hole cut therein. Each of the faces of this hole is beveled off at Z), the angle of the beveled portion depending upon the angle at which the flaps are to open out. 0, cl, 6. f, g, h, 7' and 7c are eight flaps. These flaps are of such size and'shape, as will be seen clearly from Fig. 2, that when they are opened outand rest against the beveled portions 6 of the framework a theiredges exactly meet. In order that they may fold over one another as shown in Fig. 1, each flap is shorter at the bottom than the preceding flap, and theflaps are attached on the sloping edges b by :means of hinges 12?.

each hinge being placed slightly higherup the slope than the hinge on the preceding flap. It will thus be observed that the hinge -m'on the flap c is higher than that. on the flap d, so that when the last flap 7c is reached this is considerably lower than its corresponding slope 71-. This enables the flaps to be all folded over one another as shown at Fig. 1, as before stated,'and yet when open the outer curved portions of the flaps all correspond, forming a regular trumpet bell when in position. In order to hold the flaps in the open position any suitable fastening device may be provided, for instance the one shown at Fig. 3, where each flap is provided with a projection n taking into a corresponding notch or cavity 7) in the next flap.

Referring to Fig. t this shows a diagrammatic view of a device such as that described with reference to Figs. 1 to 3 attaeli ed to the front of a cabinet of a talking machine. It will be understood that the tone armconnected with thesound box is prolonged into or communicates .With a trumpet which is bent in such a way as to "avoid the motor and opens at the side of fforming the bell are similar to the flaps 0, "d, is already described. To the other side thecabinet at the bottom ofthe flaps at the octagonal aperture in the frame a.

-Re'ferring to Fig. 5 this shows a method of constructing an entire trumpet according tomy invention.- In this case 9 is an octagonal frame made with a series of steps,

so'that the flaps may fold fiat over'one another as beforeexplained. The outer flaps i of-each step is hinged another flap, of di- 0 minishing taper, 7 1 29 gu being preferably provided ateach side of s the finished trumpet.

Having thus described a practical and preferred embodiment of the invention, the particular features of novelty WillnoW-be inted out more succinctly the follow- 1 claims: 11g

1'. A trumpet comprising a support havingn polygonal aperture therein and aplurality of sectional trumpet flaps, each flap scribed.

2. A trumpet comprising a support provided with a polygonal aperture having beveled edge faces, and a sectional'trumpet flap pivotally connected to each beveled face at a position varying from thepivotal position of its complementary flaps, substantially as described.

3. A trumpet comprising a, centralsupport having a polygonal aperture therein, a plurality of sectional, trumpet flaps, each flap, pivoted to' said support adjacent an edge of said aperture on one side of said support, forming the bell portion of the trumpet when assembled, and a plurality of sectional flaps similarly connected-to the opposite side of said support and forming a continuation of the bell portion. ,of the trumpet, the Whole arranged so that both sets of saidflaps may be folded into flat superposed position, substantially as described.- v

In testimony whereof, I affix my signature, in presence of two Witnesses.
