HORN BRACKET Filed March 21. 1927 Patented Sept. 24, 1.929
UNITED STATES PATENT OFFICE FARNUM F. DORSEY, OF ROCHESTER, NEW YORK, ASSIGNOR TO NORTH EAST ELECTRIC COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK HORN BRACKET Application filed March 21, 1927. Serial No. 177,069.
This invention relates to a bracket for supporting a horn or sound signal of the type in which a diaphragm is magnetically vibrated. In the use of horns of the type in question, it has been found that their operation is better if they are supported upon brackets having provision for a certain amount of resiliency, such as will permit the body of the horn to vibrate to a slight extent. At the same time it is desirable to prevent the body of the horn from oscillating or moving in any direction except that of its longitudinal axis.
To secure the results just mentioned, it has become customary to mount magnetic diaphragm horns upon brackets in which parallel spring plates are used to provide the necessary resiliency and at the same time prevent undesirable movements of the horn. The present invention relates to a bracket of this general construction, and one object of the invention is to produce a bracket which will be simple and inexpensive, but at the same time strong and rigid in all directions except that in which resiliency is desired. A further object of the invention is to adapt the bracket particularly for attachment to the horn by means of the screws by which the forward and rearward parts of the horn are secured together.
To the foregoing ends the invention consists in the bracket hereinafter described as it is defined in the annexed claim.
In the accompanying drawings Fig. 1 is a side elevation of a bracket embodying the present invention, together with a portion of a horn supported by the bracket. Figs. 2 and 8 are a rear elevation and a plan view of the bracket Fig. 3 being partially in section on 0 the line 3 3 in Fig.
The illustrated bracket comprises a base plate 5, which is perforated to adapt it to be secured upon a cylinder stud or other convenient part of a. motor vehicle. The forward end 6 of the base plate is bentupwardly to a vertical position, and two spring plates 7, 7 are attached to the opposite faces of the part G, by means of rivets S. VThe bracket is adapted for attachment to two of the screws 11 by which the forward and rear parts of the horn 10 are secured together. Accordingly, the plates 7 are provided with perforated ears, as shown in Fig. 2, and in each corresponding pair of ears a bushing 9 is fixed, this bushing being shouldered to space the ears at the required distance, while the ends of the bushing are flanged or spun over against the spring plates, thus securing the bushing lirmly in place. The screws are elon gated to pass through ythe bushings, and nuts 12 secure the parts together.
The bushings 9, in addition to suitably spacing the upper extremities or ears of the spring plates at the same distance as their lower extremitiesy and' thus maintaining them invtheir parallel position, also have the advantage that they provide long smooth bearing surfaces to engage the threaded surfaces of the screws 1l. In previous brackets of the kind in question it has been customary merely to introduce a loose spacer, of sheet metal, between the upper ends of the spring plates. This spacer serves to hold the spring plates apart at the required distance, but does not effectively increase the bearing surface against the screw, which is limited therefore to the narrow edges of the thin spring plates. In the present construction the spring plates do not bear or press directly against the screw threads, but the vertical strains incidental to maintaining the horizontal position of the horn are distributed over a large part of the screw by means of the smooth inner surface of the bushing.
rlhe invention claimed is:
A horn bracket comprising a substantially rigid base member, two parallel spring plates fixed to the base member and provided with
