MOTOR-WINDING MEGHANISM.

Speccation of Letters :Patent Patented Api; 23, 1912.

Application led May 5, 1911. Serial No. 625,144.

To all whom 'it may concern:

Be it known that I, ALEXANDER H. IVEL- RER, a subject of the King of Great Britain, residin-g at Berlin, in the county of Waterloo, Province of 'Ont-ario, Canada, have invented certain new and useful Improvements in Motor-Winding Mechanism, of which the following is a specification.

This invention relates to talking-machines and is directed to the provision of certain improvements in machines of this character With respect to the mechanisms for Winding plying a Winding-handleto the end of this shaft. If such a Winding-handle be removed from the shaft, it is apt to become misplaced, thus causing considerable inconvenience when it is necessary to rewind the motor. If, on the other hand, the Windinghandle be allowed to remain in place upon from the appearance of the machine-as a Whole, particularly in the case of a machine of the so-called hornless type, having a handsomely finished casing.

This invention involves the provision of a Winding mechanism for a talking-machine motor, which, Without detaching it, may be moved to inoperative position Within the casingof the instrument or'caused to take an operative position exterior to the casing of the instrument, at will. With this construction, the motor may be Wound by turning the handle when the latter is in its operative position, and thereafter the handle may, Without detaching it from the winding-shaft, be moved within the casing and a door in the casing closed over it, so that the Winding mechanism is entirely concealed.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in Which- Figure 1 is a front view of the upper portion of a talking-machine, broken away and sectioned in part; Fig. 2 is a top view of a portion of the machine, broken away and sectioned in part; and Figs. 3 and 4 are detail views hereinafter referred to.

The drawings illustrate a machine of the horiless type,-in which the sound-conveying and -amplifying horn extends downwardly and through the casingof the instrument.

1 indicates the casing, having a hinged cover Q, which normally conceals the turntable, the sound-record thereon, the reproducing mechanism and the pivoted tonearm.` The tone-arm connects with a tapering sound-conveying and -amplifying device 3, which extends through the casing of the instrument from the rear to-v the front thereof. The motor is mounted Within the casing, above the conveyer 3 and below the turn-table Within the cover 2. The Winding-.shaft of this motor is shown `at '4. In the present instance, its end passes through a partition 5 Within the casing 1. A support 6 is secured upon this end of the Winding-shaft 4. Preferably, this end of the l Winding-shaft is threaded, as shown in Fig,

3, and the support 5 has a threaded opening in one end thereof, adapted to fit upon the threaded end of shaft 4. Vhen the support is in position upon shaft 4, -it is secured against rotation relatively thereto by a pin 7 or other suitable means. Beyond the end of the shaft 4, the support 6 has a longitudinal slot therein to receive the end of the winding-crank S, Whose end is provided ith a handle 9. The walls on opposite sides of the slot in the support 6 are provided' with slots 10 extending lengthwise of the support, and these slots receive the ends of a pin 1l passing through the end of the handle 8. In,`this Way, the handle may move relatively to the support in the direction of the length of the support an amount i port, as by means of the screw7 13. At its other end, the spring engages the ends of pin 11, so that the spring constantly exerts a tension tending to move pin 11 and handle 8 to the left in Fig. 3, that is, toward the Winding-shaft 4. The end of the support (i is curved, as shown at 14, to provide camsurfaces on opposite sides of the slot, With which surfaces the ends of a pin 15 coact, this pin extending through the crank 8. At the center of these curved surfaces are notches, as shown in Fig. 3, to receive the ends of pin 15.

Figs. 1 and 3 show the operative position of the Winding-handle 8. In this position, the pin 15 coacts With the Walls of the notches in the curved end of support 6,

so that turning the handle 9 will turns@- -.the pinv1 moves around the curved sur` the casing through which the crank 8 is so moved, may be closed by means of a hinged pin 15 engage the curved surfaces Hand 'those surfaces act as cams, moving the sition, substantially. as set forth.

port 'and with it the winding-shaft 4, to which it is secured. After the motor of the talking-machine has been wound up, the crank 8 is brought to a substantially hori- Zontal position and pulled outwardly slightly, against the tension of spring 12, until the pin 15 is out of the notches with which it coacts. Such movement of crank S is permitted by the slots 10 which receive the ends of pin l1. IVhen this movement of the. crank has been effected, the latter is swung aboutthe pin 11 as a pivot, and as face at the end of support 6 the spring 12 will move the crank relatively 4to the support 6 until the pin 11 has reached the inner end of the slots 10. The handle may thus be turned to the inoperative position, in which it is shown in Fig. 2, in which position it lies wholly within the casing 1 of the machine. The opening in the wall of door 16, as shown in Fig. 1.

In turningA the. crank from the inoperative to the operative position, the ends of crank in a direction to extend spring 12 until pin 15 comes opposite its coacting notches, whereupon the handle 8 is moved by spring 12 to carry pin 15 into the notches with which it coacts.

Having now described my invention, what I claim as new therein vand desire to secure by Letters Patent is as follows 1. AIn a talking-machine, the combination of a casing having a compartment therein, a door closing said compartment, a wind-l ing-shaft projecting into said compartment, a winding-crank applied to said shaft, and means permittingT movement of said crank to an inoperative position Within said casing and permitting closure of said door or to an operative position in which it extends beyond said casing, substantially as set forth.

2. In a talking-machine, the combination of a casing having-a compartment therein,V a door closing said compartment, a Winding-shaft wh/osc cnd projects into said compartment, a\\'indingcrank pivotally connected to said cud of the shaft and' Inovable relatively to the shaft to inoperative position in which it lies witliin the casing and permits closure of said door or to an operative position in which it extends bef yond said casing, and moans for securing the crank against movement relatively to the shaft when the crank is in operative po- 3. In a talking-machine, the combination with a casing having a compartiment there-l in, a door closing said compartment, a

compartment, a winding-crank pivotally' connected to said end of the shaft and movable relatively thereto to inoperative position within the casing and permitting closure o'f-said door or to operative position in which it extends beyond the casing, said crank when in operative position extending from said shaft in a radial direction beyond the wall of said compartment, and means for securing the crank againstmove` ment relatively to the shaft when the crank in operative position, substantially as set forth.

4. In a talking-machine, the combination of a casing having a compartn'icnt therein, a door closing said compartment, a Winding-shaft. whose cud. projects into said compartment, and a crank connected to said cud of the shaft and movable relatively thereto in the direction of lthe length of the shaft and about an axis transverse to said length, the r'novement of the crank about said axis carrying the cra-nk to inoperative position withiny the casingand permitting closure of said door or to operative position projecting through said opening and beyond the irasiug, and the movement of the crank in the diroctionof the length of the shaft coupling the crank to or uncoupling it from the shaft, substantially. as set forth.

In a talking-machine,'the combination `of the winding-shaft, the crank, the walls prevent turningof. the crank relatively to the winding-shaft, and.l the spring to hold said pin yieldingly in connection with saidv notches, substantially as set forth.

6. In a talking-machine, the combination of the winding-shaft, the crank, the Walls on said notches formed thereln, said crank being pivotally mounted bet-Ween said .walls by a pin-and-'slot connect-ion, a pin on said crankadapted to coact with said curved ends and notches, and a spring acting on said crank curved ends and notches, substantially as set forth. j
