MUSICAL ALARM Filed April 11, 1924 2 Sheets-Sheet 2 176%)? fi/affiZ/MZZZ INVENTOR WITNESS: AfiuRNEY Patented Dec. 9, 1930 Unirnn s rains HENRY FAHRENHOLTZ, F DAYTON, KENTUCKY, ASSIGNOR OF ONE-THIRD T0 JOSEPH FAI-IRENI-IOLTZ AND ONE-THIRD T0 ELZIE MUSICAL Application filed April 11,

This invention relates to alarm device, and has for its object the provision of an alarm mechanism including a clock associated with the starting and stopping lever of a talking machine whereby to release the brake and permit the record table to rotate at a certain predetermined time whereby music will be produced.

Another object is the provision of a device of this character which embodies electric lights so arranged that the circuit thereto will be closed when the alarm is set off. I

Yet another object is the provision of a device of this character which need not be used in connection with music records but which can be adapted for use with records of a different type for calling out stations in railroad depots and the like, there being no restriction as to the mode of employment.

An additional object is the provision of an attachment of this character which will be simple and inexpensive to manufacture, easy to install, positive and eflicient in action, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a fragmentary front elevation of a talking machine equipped with my device,

Figure 2 is a section on the line 22 of Figure 1,

Figure 3 Figure 2,

Figure 4: is a plan view, Fig. 5 is a detail view.

I Referring more particularly to the drawings the letter A designates a talking machine of the cabinet type within which is rotatably mounted the usual turn table B for supporting records to'be played. As is well known, machines of this type are equipped with a brake device operated by a lever G operating usually within a guide D. v

In carrying out the present invention I provide an alarm clock 10 which is mounted within thevcabinet to the rear of an opening 11 in is a section on the line 3-3 of WINTERS, BOTH or DAYTON, KENTUCKY ALARM 1924. Serial No. 705,887.

the front thereof so that the clock facemay 'be seen, the clock shown is of the alarm type and has a winding key 12 for the chronometer mechanism, a separate winding key 13 for the alarm and an indicator 14 which is operable to set the alarm mechanism to be released at any predetermined time. There is nothing peculiar about this clock except that the winding key '13 is shownas forked for a reason which will be made apparent.

Let into the top board or panel of the cabinet is a support 15 of insulating material ,within which is mounted a fixed contact 16 and a spring contact 17 normally spaced away from the fixed contact. lVhile it is not essential I have shown the front of the cabinet as having sight openingsl?) behind which are mounted sockets containing incandescent bulbs 19 both of which have one terminal 20 connected with a wire-21 leading to one pole of a source of current 22. The other terminals of these bulbs are connected by wires 23 with a wire 24: which connects with the sta tionary contact 16. The spring contact 17 has connected therewith a wire 25 which leads to one'elment 26 of a switch including amovable element 27 connected with the other terminal of the source of current.

On the spring contact 17 is an upstanding projection 28 located to be engaged by the lever C, and carried by the free end of this lever is a post 29 with which is detachably connected, a fork- 3O ordinarily heldin place by a set screw 31. Pivotally connected at 32 with this fork is a rod 33 which is adapted to be engaged with the forked key 13 and which has a head 34 operating to hold it as sociated withth'e key. 7

In the operation, the spring motor of the talking machine is put under tension, a record is laid on'the platform. B, the lever G is placed in its stop position and the clock is wound and set to go off at a certain desired time. The switch 27 must then be closed.

After this is done, it will be seen that the contact 17 will be out of engagement with the contact 16 so that no current flows through the circuit. When the appointed time arrives, the alarm mechanism is released in the ordinary manner whereupon the key 13 will turn and owing to the engagement of the rod 83 therewith it is apparent that a pull will be exerted on this rod which will result in swinging the lever G into its brake releasing position so that the record turn table will turn. Quite naturally when the apparatus is first set the stylus must be placed in position in the first groove of the record. When the lever C passes over the hump 28, it is apparent that the spring contact 17 will be forced downwardly into engagement with the contact 16, thus closing the circuit through the bulbs 19 so that they will illuminate the room.

To render the device inoperative, it is intended that the set screw 31 be loosened so that the fork member 30 may be disengaged from the post 29. It will be observed that in Figure 3 the switch device is shown diagrammatically while in Figure 4 I have illustrated it as a push button type indicated by the letter S. It should be however understood that there is no restriction in this respect as many changes, variations and modifications may be resorted. to not only in these particulars but in many others. I furthermore wish to have it understood that the device is not limited for use as a household article inasmuch as special records might be employed which would permit the device to be used with great advantage in railroad depots for announcing trains and the like. any other uses will naturally suggest themselves to a thinking person and the right is reserved to make all such adaptations as will not depart from the spirit of the claim.

I claim:

Means for starting the operation of a talking machine including a turntable for supporting a record and further including a brake lever adapted normally to hold the turntable against rotation, comprising a chronometrically released rotary element carlying a forked member, a member mounted on the brake lever near the free end thereof and provided with an car, a rod pivotally connected with said ear and having its free end terminating in a head, said head being engageable within said forked member whereby upon rotation of said rotary element said forked member will operate to pull said rod and swing said lever into released position to permit rotation of the record carrying turntable.

In testimony whereof I aflix my signature.

HENRY FAHRENHOLTZ.
