UNITED STATES PATENT. OFFICE.
EZRA W. VANDUZEN, OF CINCINNATI, OHIO.
ALARM-GONG.
SPECIFICATION forming part of Letters Patent No. 628,133, dated July 4, 1899.
Application filed March 8, 1899.
To all whom it may concern:
Be it known that I, EZRA W. VANDUZEN, residing at Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new and useful Improvements in Alarm- Gongs, of which the following is a specification.
My invention relates to a gong for patrol- Wagons, street-cars, and other similar alarm purposes.
The features of myinvention are more fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 is a central vertical section of my improvement in position foruse. Fig. 2 isa top plan view. Fig. 3 is a similar view with the gong removed. Fig. 4 is a central vertical section through Fig. 3.
A represents the gong, and B the supporting-piece, secured to the platform or other suitable place. t represents a stop on the lower portion of this piece. (See dotted lines, Fig. 3.) O represents a stud centrally projected from said support.
D represents the vibratory hammer, provided with a central slot E, through which the stud 0 projects. The upper end of the hammer passes through the journal-bracket a. The lower end tprojects through the lower part of the support. It is bent down so as to form a striking-lug 1) within the gong, while the bent end tis free to be struck by the foottreadle.
F represents a spring attached to the hammer and bearing against the bracket or and outside of the slot E.
G G represent rubber buffers attached to the top and bottom of the stud, adapted to be struck by the inside end portions of the slot E. The spring holds the hammer normally down, so that buffer G is normally in contact with the upper end of slot E, as shown in Fig. 3.
H represents the foot-treadle, pivoted at c to the wagon-bottom. The outer end engages the end 25 of the hammer. When the treadle is struck, the outer end hits hammer endt and drives it upward and is prevented from following it upward by contact with stop t. The blow compresses the spring and also the bufier G against the lower end of slot E, so
Serial No. 708,171. (No model.)
that the upper end of the hammer hits the gong and is recoiled by the spring and buffer. The force of the recoil in turn compresses the buffer G against the upper end of the slot E, allowing the striking-lug b to hit the lower portion of the gong. The result is two sharp clear rings, the hammer being held from contact with the gong by the bufiers engaging with the slot E. The gong is secured to the stud O by screw-bolt e tapping said stud.
Having described my invention, I claim 1. In a gong, the combination of a support, a central stud, a vibratory hammer provided with a striking-lug at each end, a slot centrally formed on said hammer and journaled on the stud, and a rubber buffer attached to each end of the stud, substantially as specified.
2. 111 a gong, the combination of a support, a central stud, rubber buffers attached to said stud, a vibratory hammer having a strikinglug formed at each end, the lower end projected from under the edge of the gong, a slot centrally formed onsaid hammer, the stud projected through the same, a j ournal-bracket secured to the support and adapted to receive the upper end of the hammer, and a foottreadle pivoted tothej wagon and adapted to engage the projecting end of said hammer, substantially as specified.
3. In a gong, the combination of a support, a central stud, a journal-bracket secured thereto, a stop formed on the lower portion of the support, rubber buffers attached to the stud, a vibratory hammer provided with an intermediate slot, the stud projected through said slot, the upper end of said hammer proj ecting through the journal-bracket, the lower end projecting under the edge of the gong, a striking-lug at each end of the hammer, a spring engaging the hammer and support, and a foot-treadle suitably pivoted, one end being adapted to strike the projecting end of the hammer, the blow being limited by the said stop, substantially as specified.
In testimony whereof I have hereunto set my hand.
EZRA W. VANDUZEN.
