' TELEGRAPH To all whom it may concern; '7

Be it known that I, DENNIS A. WHITNEY, a citizen of the United States, residing at Holland, in the county of Erie and State of New York, have'invented certain new and useful Improvements in Telegraph-Sounders, of which the following is a specification.

, My invention relates .to improvements in telegraph-Sounders, and particularly to the resonator or sound-ampli'iying, .device for use in connection with telegraph instruments The manobjectjiofjmy invention is to provide means for.}ampli-fying or increasing the sound made by the ordinary main-line relay, so that-the use. ocal sounder wll not be necessary and? th messages may be read direct lrolntliere Further obj'ec -of my invention are to produce a resonator for telegraph. instru. ments whiclrmay be readily applied to the quirement s, and which will render the faint clicks ordinarily produced by. such instrufurther objects being to produce such a device in simple and compact form thoroughly practical and efficient.-

To attain the desired objects, tllBiilVOlltiOl'i' consists,"primarily, jof a pair of drums or resonating-cliambers between which the armature of the telegraph instrument isadap ted to vibrate, said drums being of such construction to increase or amplify the sound produced by such vibrations, and. the inventlOIl further comprises certain other novel featurcsfof construction, combination, and arrangement oi" parts, substantially as herein set forth.

Specification of Letters Patent.

Application filed November 15.1906. Serial No. 243,553.

Figure 1 is a side elevation ol" my invention as applied to the iannhar and well-2 known type of. telegraph instrument known asthe main-line rclay.: Fig. 2 is a front end elevation 01"" the same. Fig. 3 is a top plan view ofthe instrument with my improvements. Fig. 4 is a longitudlnal sectional view of the complete apparatus, and Fig. 5 is a sectional View taken through one of the resonating-chambers on line 5 5 of 9' Fig. 4. i

The main-line relay illustrated in the acconu mnying drawiws is of the usual and ordinary construction, comprising a base 1, at

pair of magnets 2, a bracket 3 for supporting the. forward end of the magnets, an armedtii're 4E, pivoted to vibrate in close proximity to the poles of said magnets, a post 5, a spring-adjusting bar 6, adjustably secured in the post, a retractile spring 7, connected to the armature, and a thumb piece or member'S "for adjusting the tension of theretractile spring. The rear ends of the, magnet's lare connected by la yoke 9, from which extends the bolt 10. A supporting-post 11 is mounted near the end 'ot the base, and through an opening provided for that purpose in .the post is passed the bolt 10, a thumb-nut 12 being' mounted upon the end of the bolt and a spiral spring lfi being interposed bet-ween the supporting-post and magnet-yoke, thereby allowing the magnets to be moved toward AhWHITNEY, or HoLLANnNEW YORK, ASSIGNOR or ONE-HALF.

or away from the armatiu'e by manipulating the thumb-nut.

The support for my resonator attachment comprises a rod or spindle 1-4,wln-ch is threaded for a-consit'lerable portion of its length and is supported in a horizontal position or parallel with respect to the base. Inthis instance l have shown this red as provided with an angular bent portion 15 ,'which issecured in the upper end of ti .e su jiporting-post 11; but thisrod may be supported upon the base in any other suitable manner. Mounted upon and freely movable on the threaded portion of the red are a pair of bell-shaped or hemispherical drums or sl':,ells'-l6, their open ends facing each other and inclosed bythe (Iiaphragms 17 the hubs or sleeves l8 beinginclosed within the shells and connecting-the diapln'agmsand back of the shell. Thumbnuts 19 are engaged upon the rodiand form abutme; s for the outer faces ofv the shells, and a spn 20,,li'il6lPUS6tl between the ad.- jaceizt faves or Uiephragms of the shells. forcesthe shells in e :gement with the ad justing-nuts. The a ju-r'o is caused to vibrato between ti striking the diaphragn'is cl each.,'and 1t vill be see-nthat by these means of the tlnunb-uuts the shells or resonators may bcadjusted upon the spindle t'ocachother or with respect to the armature,

The shells orresol11tiling-chambers may be f made 'o'f any suitable n'u-iterial st1cl1 as 1 metal, hard rubber, woo'd,.,. c;c.and thense strument aiid iendefsthe same very clear and distinct. 1

From the foregoing description, taken in connection with the drawings, it will 'be evident that i have accomplished all the-ohjects herein set forth and have produced a.

practical resonator for telegraphic instru- V ments.
