SPEAKING-TRUMPET- itlg: fitlpiml: rztmtb ts in tigtst 321m game m making part at its an.

To ALL WHOM I T' MAY CONCERN: I i

Be it lnfiawn thst L-Fnnn. J. MILLER, of Brooklyn, in the county of Kings, and State of New York, have :invented, nude, and applied to use it ccrtninnew and useful Improvement in Fire-Trumpets; and I do hereby declare the following to be a. full, clear, rind exact description cf'said invention, reference being had to the snnexed drawing, melting part of this s ecification, which represents, in

Figure 1, 1 section of my improved trumpet open-for use, and

Figure is shown the trumpet whenv closed.

Biuilsr marks of reference denote the some parts.

a is the mouth-piece; b, the bell. c is a. tube, permanently attached to the mouth-piece. d cf, In are I movable rings, msdo tapering, that is, smaller at the top than at the bottom. I: is o wire, soldered around the top edge of the hell 6. Z Z are catches, soldered to the mouthpiece. m is an opening in the wire 1:, which allows .the cstches' to 'p'sss through said wire, the catches Z Z holding the mouth-pioce in place, as shown in fig. 2.

Trumpets sre'much used by firemen and others, and when not in use occupy a great deal of room, and the object of my invention is to produce astrumpct that'will he so constructed that when it is not in use can he'com veniently csrriod in tho p'ocket; to accomplish which I construct a trumpet in the following menner:

I mske my trumpet of brass, German-silver, or any other materiel, and form the mouth-picee a in the usual way, shown in fig. 1, to which is permanently attached the tube a. i d is a. movable ring, heing made smaller at the top then at the bottom, but larger at the top than the lower part of 'tho-tube c,.so that when-drawn down the ring (1 will slide over but not entircly'ofl' the tube e. cf It i are also movable rings, each ring being msde smaller st-the top then at the bottom, so that the lower part of ouch ring will bind tightl y'srou n ithe upper v p'ert of tlie ring just below it when the trumpet is pulled out to its full extent. The upper edge of the ball 6 is made of seize inside'smsller then the outside of lower part of the ring 2, so that it prevnts o ring itfrcna entirely passing through the bell. At 1, I provide catches, which nrenttachod to mouth-piece,v and when the mouth-piece 'is pressed down, the chtches yrill slip over the urine 1:, through the opening rig-fig. 2. Then, if the mouth-piece is turned partly around, it will be held in its plcce j by the catches I. At a, I provide a stop to prevent the niorshle ring from psssing through the hell. i

when" the trumpet is required to be used, it is only necessary to .turn the mouth-picce around until the catches! ere opposite the openings m,'and.then raise the mouth-piecuntil all the rings are drswn out and bind tightly together,'snd it is then in condition to be used the sumo as any other trumpet mode in the usual way without the movable rings or sections. I v

when the trumpet is to be carried in the pocket, by simply pressing the mouth-piece and bell together, end

pnssingthe catches l thropgh the openings m, and then by turning the mouth-pieco.pnrtly around, the trumpet will then ho reducc d to the shape and siseehown in fig. 2, which will readily be soon and can be conveniently carried in the pocket I I Having thus fully doscrihed'my invention, what I claim, and desire to secure by Letters Patent, is

As 0. neiv article of manufacture, a. pochct-trumpct, made in suhstantially the insnnor described and shown, end for the purposes set forth.

In witness whereof, Iihuvo hereunto set my signature, this 16th dsyof March, 1868;
