To all whom t may concern.'
Be it known that I, VICTOR E. ToLLEEsoN, a citizen of the United States, residing at Elk Point, in the county of Union and State of South Dakota, have Yinvented new and useful Improvements in Automobile-Horns, of which the following is a full, clear, and exact description. l
My invention relates to horns, and particularly horns for automobiles, launches, and the like, designed to be operated by the exhaust from the engines thereof.
The object of my invention is to provide a series of pleasant sounding resonant tubes adapted to be sounded simultaneously to produce a. harmonious combination of sounds, for the signaling and warning purposes for which the instrument is intended.
A further object of my invention is to "accomplish the foregoing results by`a simple and economical construction nfl-parts that will be' held irmly together and withstand the jars and vibrations to which the instrument, particularly when used as an automo` bile horn, will be subjected. This I accomplish by the means hereinafter fully described,
and as particularly pointed out in the.
In the drawings, Figurel is a side View of my invention. Fig. 2'is a transverse section thereof taken on dotted line 2--2, Fig. 1. Fig. 3 is a transverse section taken on dotted line 3, 3, Fig. 1.V Fig. 4; is a longitudinal central section of the lower part of the instrument and adjacent portions of the horn connected thereto.
My invention is adapted to be securedito A the exhaust ipe of the engine of an automobile or ot er vehicle by means of a couplingA. This coupling is tubular in construction, and about its center of length its bore is divided by a transverse partition a,
whichis, preferably, somewhat dome-shaped,
said coupling. This edge is provided with recesses c, c, next the upper ends of said nozzles, substantially as shown. Near the upper end of the coupling it is provided with a circumferential platform C, and this platform has'its outer edge provided with a circumferential ange d, that projects from the periphery thereof toward the tubes, and terminates in the same transverse plane as the upper edge of the coupling. Opposite,
.and in the same radii as the upper ends -of nozzles b, b, and recesses o, a, this flange d is cut-away or that are, cesses c,\su stantially as s own in the drawings. A
The lower open ends of the four resonant tubes are cut off obliquely, and are inserted down into fand secured in the sockets of a metallic holder or cage, substantially as shown. This holder consists of a base portion F, from which four equi-distant sockets f, f, arise, the inner circumferences of whichk rovidedA with recesses e,
correspond to the outer circumferences of the tubes, and when the tubes are inserted from above the downward movement thereof islimited by their lower ends coming in contact with the inclined orv countersunkv surface g at the lower ends of the sockets. Near the outer surfaces the ,sockets are provided with transversely elongated mouths 4Gr, and the front of each socket, and also the rear portions thereof nearest the center around which said tubes are arranged', are cut-away above the plane of the mouth so as to lighten the weight`of the holder, and so as to renderk the merging walls of the sockets somewhat elastic.
The reduced lower end of each socket is provided with a reduced opening h through which the discharge from the nozzles b, located below and in line therewith, discharges. The rearmost'portion of each of these openin s is closed by a segmental web y', the ob]ect o which is to deiect the current of the discharge from the nozzle forward as it enters the tube.
Now, where the tubes are assembled in the holder, the oblique edges of the lower endsv thereof are made to face outward, and the highest segments of the said lower edges tery minate in about the same plane as the uppermost portions of the mouths G of the sockets. When in this position and the ex-i haust gases of the automobile engine are referab y, lar er thanv the reshrieking.
discharged through the coupling and nozzles b into the tubes B the latter emit a sutiiciently loud and harmonious combination of sounds ,to perfectly fulfil the requirements of this class of instruments, without The surplus volume of exhaust gas escapes out through recesses c and c and the hissing of the tubes as they yield up their harmonious voices is thus avoided.
In order to retain the tubes firmly in their assembled positions, I surround them at a poin't near the upper ends of the sockets of the holder with an inclosing frame H, which latter is, preferably, made of cast metal, and I provide this frame with a series of. four equi-distant lugs lo, 7c, that depend downward and lap over and down past the upper edges of the holder midway between adjoining sockets. Screws m, m, extend through these lugs 7c, le, through the metal connecting adjoining sockets betweenA the tubes, and their inner ends and are tapped 'into a central boss K. It is obvious that if these screws are tightened, the webbing composing the sockets, conterminous with the longitudinal slots or cut-away portions thereof, will clamp the tubes correspondingly tighter.
I also provide a frame J for retaining thetubes in their assembled position, which is located at a point farther away from said sockets than frame H. This frame J consists of a cast metal member, the webbing of which entirely surrounds each tube and is solid and unbroken between the same. This frame is held in place by a bitof solder, or in any other suitable manner. Of course both frames, H and J, may be dispensed with, if desired. I much prefer their use, however, or their equivalents.
lVhat I claim as new is 1. A horn having a coupling, a holde -having a base .connected to the coupling, said base having apertures therein, said coupling having lateral openings corresponding to the openings in theabase, sockets on said base, tubes having closed outerends and open inner ends, the said open ends of the tubes being seated in the sockets, and means for conducting exhaust gases from the coupling through the openings of the base. t
2. A horn having a coupling, a holder having a base connected to the coupling, said base having apertures therein, said coupling having lateral openings corresponding to the openings in the base, sockets on said base, tubes having closed outer ends and open inner ends, the said inner ends being beveled, the said open ends of the tubes being seated in the sockets, means for conducting exhaust gases from the coupling through the openings of the base. v
3.
