SPECIFICATION forming part of Letters Patent No. 627,799, dated June 27, 1899.
Application filed August 31, 1898. Serial No. 689,934. (No model.)
To all whom it may concern:
Be it known that I, J nssn H. BUNNELL, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have made a new and useful Improvement in Telegraphic Sounders, of Y which the following is a specification.
My invention is directed to improvements upon an invention disclosed in a prior patent granted to me on the 7th day of May, 1895, and numbered 538,816; and its objects are, first, to provide means for obtaining better sonorous results than is possiblewith the invention disclosed in the aforesaid patent, and, second, to provide means for efiectually protecting a thin wooden base like that disclosed in my prior invention in such manner as to prevent damage thereto during shipment and also to give to the entire structure such strength and stability as will make it possible to construct the wooden base or diaphragm of very thin sonorous material, such as wood.
My invention will be understood by referringto the accompanying drawings,in Which- Figure 1 is a full-sized side elevational View illustrating the same, and Fig. 2 an end elevational view of the instrument as seen looking at Fig. 1 from the left toward the right plate A should be about three-eights of an" inch in thickness, although the thickness may vary according to the resonating nature of the wood or material from which it is construoted. This second base or plate A is in turn supported at a plurality of points, preferably at three, as before, by metallic washers r r r and screws 8 s s, the latter extending upwardly through a protecting base or plate A into the base orplate A, said base or plate A being preferably of aluminium and of the thickness shown.
F F represent the anvil of the sounder, se-
resonator base or plate B and provided with I trunnion-screws for pivotally supporting the armature-lever K in the manner shown, the usual adj usting-screw being provided at one end of the armature and a retractile spring and adj usting-sorew at the opposite end thereof. The anvil F F, electromagnet M, armature-lever K, wires to w, and binding-posts B B together with the adjustable parts shown, constitute the operative parts well known in existing forms of telegraphic sounders I In my prior patent, 'No. 538,816, granted May 7, 1895,I have described and claimed a resonator base or plate supported at a plurality of points within its outer edges and not in contact with the main base of the instrument at any point or points, excepting those required for the supports, the edges of the resonator-plate being free to respond to Vibrations communicated by the anvil, seated or supported within the area inclosed by the supporting-points.
.I have discovered that increased sonorous or resonating effects may be obtained by supplying additional resonator bases or plates and that the best effects are to be had by constructing at least one of said bases or plates of thin sonorous or resonating wood, the base or plate 'A in the present instance being, as before'described, of this nature. It is also an essential'element in the present improvement that the edges of all of the bases or plates B, A, and A shall be free or unsupported, except at such points of support as will give the best results, in this instance three points of support for each base or resonator-plate, as r 'r r r r 4", said plates being secured together by screws 8 s s s s s, as described.-
The third base or plate A being of metal also acts asa protecting medium to the thin wooden plate A, thereby making it possible to construct said intervening plate of much thinner material than would be possible where wood alone was used.
I do not limit myself to any definite number of interconnected sonorous or resonator bases or plates less than three, this feature of my invention being an improvement upon the invention disclosed in my prior patent to the extent that increased sonorous or resonating effects are had by the addition of further resonator bases or plates so interconnected or related that the intermediate base or plate may be of thin resonating material, such as wood, and the interconnections such that the edges of all of the bases or plates may vibrate freely under the action of the anvil supported directly bythe upper base or plate.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent of the United States, is
1. A telegraph-sounder having a compound base made of three or more interconnected plates, one ofsaid plates being of wood and rigidly held between the others, and in such manner that the edges of all of them shall be free to vibrate the lower plate of the set being of metal and constituting a means for protectin g the others, substantially as described.
2. A telegraph-sounder consisting of an electromagnet, an anvil, and armature-yoke rigidly secured to a resonator base or plate, the armatu re-yoke being provided with means for pivotally supporting the armature-lever over the magnet and the anvil; in combination with two additional bases or plates, all of said bases or plates being so interconnected that their edges are free to vibrate under the action of the anvil and the armature-lever the lower plate of the set being of metal and adapted to afford protection to the other plates, substantially as described.
3. A telegraph-sounder having three or more base-plates interconnected with each other at independent points of support,so that their edges are all free to vibrate, one of said base-plates being of wood and the upper one supporting directly the sounder-magnet, the anvil and the yoke of the armature-lever; in combination with limiting and adjusting screws for regulating the efiects of the instrument the lower plate of the set being of metal and acting as a protecting medium to the thin intermediate Wooden plate or plates,substantially as described.
In testimony whereof I have hereunto subscribed my name this 24th day of August, 1898.
JESSE H. BUNNELL.
