ATTACHMENT FOR PHONOGBAPHS.

nausea.

To all whom'z't may concern:

Be it known that 1, Louis H. :HAYS, a citizen of the-United States, residentof Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful .lmprovement in Attachn'ients for Phonographs, of which the following is a specification, the principle of the invention being herein explained and the best mode in which l have contemplated applying that principle, so as to distinguish it from other inventions.

This invention relates to phonogra or talking machines, particularly to talking machines of the disk record type such as the Victor and Columbia.

The object of the invention is the provision of a simple and inexpensive attachment for use in connection with such machines to automatically stop the same when the end of the record has been reached.

To the accomplishment of the above and related ends said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constitutin however, but one of various mechanical orms in which the principle of the invention may be used.

In said annexed drawing: Figure 1 is a broken perspective. view of a talking machine of the type in hand, specifically a Victor Victrola, with my improved braking at- V 2 is a top plan view of such attachment; Fig. 3 is a bottom plan view of the same; Fig. 4 is a transverse section therethrough on the line 4%, Fig. 2; and Fig. 5 is a perspective view of a sound box such as is used'in machines of the class in band, together with a clip mounted thereon to cooperate with my braking attaclnncnt as will presently appear.

Referring to the drawing, particularly Fig. 1, will be seen to designate the cabinet or box of the machine upon the top of which, mounted shown in Fig. 4, or tamiliar on a suitable turn table 1/. is a fial circular disk record construction. This dish merely frictional rests on the table a, being properly centered by being provided with an aperture 71 that engages with a central pin a on such table, see Fig. l ivotally mounted adjacent to the table so as to permit its free end to swing across the disk is the tapering arm A that communicates with the Specification of Letters Patent. Application filed July 8, 1808.

Patented Oct. 112, 1 9ml. Serial No. 4, 12,444.

I horn of the machine, such horn being concealed in the cabinet in the'particular machine illustrated. The outer end of the horn is provided, among other things, with a sound box a that bears a needle that c0- operatcs with the disk to produce the sound. in operating the machine, as will be recalled such needle is started at the outer edge or. periphery of the disk and follows the spiral record groove until it arrives at the center.

Heretofore it ha. been a source of no small inconvenience in the use of machines of the class in hand to note the arrival of the needle or sound box at the end of the record. and incidental completion of the record. in order to stop the machine, which is desirable not merely to keep the motor from running down and promptly cut ott' the sound, but also, and more important. to prevent the tapering .rm from jumping across the disk and by engagement of the needle with the disk to damage the record thereon.

My brake attachment comprises. then. a n'uember. designed to loosely rest on top of the disk. being held in place thereon by on gaging with a central aperture 1' the same pm (1 that serves to locate the disk on the table. This member, which is preferably made of metal and is circular in form. is yu'ovidcd on its under side with pads c of friction ma tcriul Fig. 3, preferably suit rubber. for cu gaging with the disk. Said member is al o provided on its upper side with a knob 1" of any suitable design whereby the member may be houvcniently handled by the user. Pivotall v mounted on the upper face of lbc member is a catch arm c adapted in one position to project beyond the edge oi the ]IHlll her to engage the sound box or corrcspoudiug part of the macluuo. when such part lies within a 'predclcl'mlucd d stance from the center of tbedisk. spring Fig. 2. tends thus to position said arm. but a trip 1- serves normally to retain the sumo in its inoperative position. 'llus trip is pro \idcd with a pin 1' adjuslably licld thcrcm so as to project at any desired distance bei'oud tlic mcuibcr. which pin is likewise iidaplcd to be engaged by the sound box. or prcthrably the needle borne by such box. This pin can accordingly be located so as to register quite exactly with the termination oi the record on'thc disk. so that as the trip i carried around by the disk'iu the course of the lattcr's rotation it will be finally brought til up against the needle of the sound box and thereby release the catch arm 0 Such catch arm immediately springs into operative position and upon the completion of the next rotation of the disk and brake member it in turn engages the needle or preferably the sound box, the disposition of the parts being properly arranged with this in view. \Vhere neither the needle or sound box aflord a convenient means for such engagement I provide a clip C in theform of an encircling spring for the sound box, such spring clip having a projecting arm 0 that will thus engage with the catch arm of the brake member G. Since the engagement of this brake member with the disk is frictional only, the stopping of the machine will not be sudden and sharp as where the manually operated stop regularly employed in machines of this character, is thrown into action, buta gradual braking efiect is exerted, which brings the motor governor, and other parts of the machine to a stop Without shock or injury to the parts.

I do not claim broadly a brake attachment for disk talkin machines, comprising a member designed to rest on top of the disk, and means borne by'said member adapted to engage the sound box, or corresponding part of said machine, as such part approaches the center of the dish and priority thereto is hereby disclaime'd.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such;

stated means be employed. 7

I therefore particularly point out and distinctly claim my invention 1.
