HERMANN EDUARD PFANNENSTIEL, OF DANTZIC, PRUSSIA, GERMANY.
'SIGNAL-SOUNDING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 404,980, dated June 11, 1889. Application filed November l0, 1888. Serial No. 290,486. (No model.) Patented in Germany August 2, 1887, No. 43,279.
nal-Sounding Apparatus, (for which I have received Letters Patent No. 43,279 of the German Empire, dated August 2, 1887,) of which the following is a specification.
The object of the invention is to produce a signal-sounding apparatus in which metal reeds are vibrated bya current of compressed air.
The nature of the invention consists in the details of combination and construction substantially as illustrated in the accompanying drawings, hereinafter described, and subsequently pointed out in the claim.
Figure l is a sectional view illustrating my invention. Fig. 2 is a sectional view illustrating a part of the same on a larger scale.
An air-compressor (designated by H) is mounted upon a proper support, as nearly as possible in the position illustrated in Fig. 1. This compressor is a hollow cylinder, in which works the'piston B. The rod M of this pist0n extends without the cylinder7 where a suitable handle is provided, so that the operator can work said piston and piston-rod with his hand.
W designates a wind-trunk, which communicates with the air-compressor. H by the flared tube T, and with the exterior atmosphere by the flared tube S. Within this wind-trunk are three coupled metallic reeds or blades f F F', fastened by the screw E to the post K at one end, and the two lov er reeds extending far enough to vibrate by the edges of and between the metallic plates P P. These reeds are preferably made of steel; but they may be of any other sufficiently strong and elastic Inetal. The plates P, between kwhich these reeds vibrate, are fastened to and supported by the post K. The upward vibration of these reeds may be limited by the screw O. At the bottom of the wind-trunk WV is a chamber L, into which compressed air flows, as hereinafter described, to limit the downward vibration of said reeds. This wind-trunk, the flared tube S, and part of the flared tube T are all surrounded by the hollow cylinder H, which forms a part of the body of' the machine. The valves o c admit air into the compressor Il', the whole device to be substantially as illustrated in the drawings.
To use my invention, the operator grasps the handle of the rod M with his hand and draws it out of the compressor, moving the piston B away from the valves o c toward the end of the compressor. As the piston moves in this direction the valves o c open and let air into the compressor; but as soon as the operator pushes the rod M in and moves the piston the other way the valves u 'u close and the air in the compressor, compressed by the action of the piston, rushes out through the flared tube T into the wind-trunk W to vibrate the reeds f F F. compressed air flowing into the chamber L limits the downward vibration of the springs, as hereinbefore specified. The remainder and by far the greater part of this compressed air passes out into the surrounding atmosphere through the tube S, carrying the sound of the reeds with it. p
This apparatus may be used in any place to which it is applicable for transmitting audible sound-signals, and will be found very convenient and efficient.
What I claim as my invention, and desire to secure by Letters Patent, is-- The combination, with an air-compressor, of a wind-trunk, metallic reeds vibrating within said wind-trunk, metallic plates within said wind-trunk by the edges of which the said reeds vibrate, an adjusting-screw arranged to limit the upward vibration of said reeds, a chamber holding compressed air to limit the downward vibration of said reeds, a tube adapted and arranged for the passage of air from said compressor to said wind-trunk, and a tube adapted and arranged to carry air from said wind-trunk into the surrounding atmosphere, all substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
