Specification of Letters Patent.

Patented June 2t, 1916.

Application filed November 21, 1914. Serial No. 873,372.

To all whom it may concern:

Be it known that I, VAssIL Cor: STANTINE, a citizen 'of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in PhonograplrStops, of which the following is a' specification.

The invention relates to phonographs, and has for an object to provide an auto matic stop therefor.

The invention contemplates, among other features, the provision of a simple device that can be readily applied to the various In the further disclosure of the invention 4 reference is to be had to the accompanylng drawings, constituting a part ofthis specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a fragmentary plan view of a phonograph" showing my device applied thereto, the full lines showing? the tone arm in its final position and the dotted lines in playing position; Fig. 2 is an enlarged vertical sectional view taken on the line 2-2 in Fig. 1; Fig. 3 is a fragmentary perspective view of a detail portion of the device; and Fig. 4: is a vertical sectional view taken on the line etl of Fig. 1.

Referring more particularly to the views, I disclose a phonograph or talking machine 10 having the usual tone arm 11 mounted to swing horizontally thereon and operate upon a record 12 carried by a table 13. rev 'oluble by suitable mechanism forming part of the talking machine and whereby rotation is imparted to the record so that a stylus '14 on the tone arm operating from the outer. edge of the record toward the inner edge thereof will travel in the grooves of the record to produce the sounds in the usual manner.

r A casing 15 supported on the top of the talking machine 10 and arranged to slide through the said casing has a stop member 16 adaptedto have its inner end engage the table "13, said stop member being actuated by a spring 17 contained'in the casing 15 and having its other end termmatmg n a suitable hook 18, an operating lever 19 being pivoted upon the top of the talking machine 1'0 through the medium of a pin' and slot connection 20 having connection with the stop member 16 as shown. 1

A sleeve 211s supported on.th e top of the talking machine and'mount'edto slide therein is a rod 22 having itsinner .end pivoted to a bell crank lever 23 mounted to swing upon suitable bearings 24: and having an arm 25 thereof terminating in a hook 26 for engagement with the h0ok-18'on the stop member 16, as shown in Fig 3.

The free end'of the'rod 22 carries an ad justable tubular member v27 which is arranged to slide upon the rod and can be secured rigidly thereon by a suitable set screw 2d, said adjustabletubular member 27 having its free end provided with a suitable head 29, the face of which is curved to conform to the curvature of the tone arm 11.

In the operation of-the device, we will assume that the stop member 16 engages'the periphery of the table, due to the action of the spring 17, the hook 19 at this time being out of engagement with the hook 26. The desired record'having been placed upon the table the tone arm'is now swung inwardly until the, stylus 1 1 lies in the innermost groove of the record and when inthisposi tion the tubular member 27 is advanced or .retreatcd'upon the rod until the head 29 of the member-27 abuts against the face of the tone arm. The member-27 is now secured rigidly upon the rod 22 by the set screw 28 and the tone armis now. swung outwardly until the stylus 14 operates in the first or initial groove of the record. Now by operating the lever 19 the stop member 16 will be moved out of engagement with the periphery of the-table and in so doing the hook 1!) will he engaged with the hook 26, it being readily seen by referring to the views that the arm 25 of the bell crank lever 23 extends at an angle to the other arm of the bell crank lever so that-the action ofthe spring 17 will not tend to exert a pull upon the rod 22. The table being now in operation, the tone arm 11 will swing inwardly the stylus 11 advances in the grooves of the record and when the stylus reaches the inner groove, 'it will be clearly seen that the tone arm will engage the head .29 of the member 27, thus exerting a push upon the rod22 and r 23 to he swung 16% and result in-the .zoolz; with the hool: stop zn'emher 16, so to the action-of the the table and stop l seription it will be e ouviee described is of a tien consists of few parts cheaply manufactured and readily ap'glied to machines or (1 my invention, 3'

posed bell crank lever-pivoted to swing upon 26 the phonograph, a hook formed on one arm of the bell crank lever at right angles thereto, a. bearing spaced from the bell crank lever and having a guide sleeve, an adjustable rod pivotally connected to the other 25 In testimony whereof I alhx my signature in presence of two WltIlGS'SQS.
