BRAKE MECHANISM FOR TOY JIGGERS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed June 21, 1917. Serial No. 176,010.

To all whom it may concern:

Be it known that I, CHARLES E. CARTER, a citizen of the United States of America, residing at Erie, county of Erie, State of Pennsylvania, have invented certain new and useful Improvements in Brake Mechanism for Toy J iggers, of which the following is a full, clear, and exact description.

This invention relates to mechanically operated toy-jiggers, but more particularly to the brake mechanism thereof, and has for its object to provide an exceedingly simple and effective mechanism of this character which will operate by gravity and the braking action of which will not injuriously affect the working parts of the device to which it is applied. My improved brake mechanism is adapted for application to any motor mechanism employing in combination a springmotor or other motor arranged to be stopped at any time that may be desirable. My improved brake mechanism is particularly designed for connection with the fly-wheel employed in mechanically operated toys of various kinds.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof wherein- Figure 1 is a longitudinal sectional view of a toy-jigger embodying my improvement, a portion only of the jigger-doll being illustrated, the section being taken on a line 11 in Fig. 2;

Fig. 2 is an enlarged fragmentary cross sectional view thereof, the section being taken on a line 22 in Fig. 1;

Fig. 3 is a similar view, the section being taken on a line 33 in Fig. 2;

Fig. 4:13 a side elevation of the device, the jigger-doll being omitted, illustrating the brake-handle in the on and ofl positions; and

Fig. 5 is an enlarged detail sectional view, the section being taken on a line 55 in Fig. 2.

In the drawing, I have illustrated a portion of a jigger or dancing doll and mechanism for imparting to the doll a jigging or dancing movement, which is accomplished by a vertically reciprocating rod to which the doll is attached. The function of my improved brake mechanism is to arrest the movement of the doll at any desired time by stopping the mechanism which imparts ing up the train which is set in motion by a spring; hence, I am able to stop the motor without injuring any of its parts.

The numeral 5 indicates a portion of a jigger or dancing doll secured to a vertically movable post 6 operated by a spring-motor mechanism, indicated as an entirety by 7 mounted within a casing 8. The motor mechanism comprises a spring 9 (shown by dotted lines) which rotates a shaft 10 carrying a gear 11 meshing with a pinion 12 on a shaft 13. The shaft 13 carries a spider 1 1, the arms of which impinge upon the wings of a disk 15, said wings being indicated by 15". The disk 15 is secured to the post 6. The wings 15 are set at an angle relative to the axis of the post 6, as shown in Fig. 2, and as the arms of the spider strike same on the under side, when the motor is in motion, the post 6 will be raised and slightly rotated, which imparts to the doll a jigging movement. Each arm of the spider will raise the disk 15, and post 6, and partly rotate same, and when the arms clear or leave the disk, the said disk 15, post 6 and doll 5 I will drop. As the legs 16 of the doll are pivotally connected to the body thereof, the vertical movement, which is comparatively rapid, will cause the legs to assume various positions simulating jigging] To balance the motor, or movement imparted to the doll, a balance-wheel 17 is provided which is carried by a shaft 18 carrying gears 19 and 20, the gear 19 meshing with a gear (not shown) secured to the shaft 13 carrying the spider lt, and the gear 20 meshing with the gear 21 which is loose upon the shaft 13 and secured to the gear 12, which is likewise loose upon shaft 13. The gear 11 operates gears 12 and 21 which operate shaft 18 through the gear 20, while gear 19, on shaft 18, operates shaft '13 carrying the spider 14:. The fly-wheel 17 acts to maintain a steady movement. The spring 9 is wound up by a handle 22 on shaft 10, a ratchet 23 and pawl 24 being utilized to maintain the spring under tension.

The just described motor mechanism forms no part of my invention, and is herein shown for iliustrative purposes only, as

my improved brake is particularly well adapted for such a type of motor mechanism; or, in other Words, a motor mecha nism employing a fly-wheel.

My improved brake mechanism consists of an oscillatory shaft 24 having a brakeshoe consisting of an offset portion (in this instance) in the form of a yoke or arms 25, 25 connected by a cross bar 26. The shaft 24 is positioned to cause the offset portion to contact with the periphery of the fly or balance-wheel 17, as shown in Figs. 1 and 3, to arrest the movement of the motor. The outer end of the shaft 24 carries an arm or lever 27, by the assistance of which the brake is applied or released. Furthermore, the shaft 24 is positioned, with respect to the balance-wheel 17, so as to cause the brake to remain in contact with said fly-wheel by gravity, the weight of the handle or lever 27 providing the pressure. In other words, to apply the brake the cross-bar 26 will be moved to a position out of line with a vertical line drawn through the center of the shaft 24, the handle 27 being also moved to such a position. Moreover, the handle or lever 27 and yoke or arms 25, 25 are out of alinement, the lever 27 being nearer the horizontal than the arms 25, 25 when the brake is applied. The purpose of this is to utilize as much of the effect of the weight of the lever as possible. When the brake is ofi, the arms 25, 25 will lie upon the bottom of the casing 8 as shown in Fig. 3, the handle 27 being positioned as shown by dotted lines in Fig. 4.

To limit the longitudinal movement or side lash of the lever, I provide the same with a stop 28, as shown in Fig. 2, said stop in this instance being located adjacent the shaft support 29.

One of the features of my invention is the manner of retaining the shaft in position. Owing to the Various offset portions, the shaft cannot be passed through a plurality of alined cylindrical openings. To mount the shaft 24, I pass same through a cylindrical opening 30 in the casing 8. Owing to the fact that the material of the casing 8 is very thin the shaft 24 can be threaded through said opening. After the said shaft has been threaded through said opening 30, the motor will be installed, including the shaft-supports 29 and 31. To engage the shaft, the supports 29 and 81 are provided with slots 32 (Fig. 5, which shows but one of said slots the other being omitted) partly surrounding said shaft 24. The bottom of the casing 8 supplies the remaining part of the bearing for the shaft 24, as said shaft passes through the side of the casing 8 at such a point as to lie on the bottom of said casing, as shown. The handle 27 serves to limit the inward longitudinal movement of the shaft 24, and the stop 28 the outward longitudinal movement.

To apply the brake the handle or lever 27 is thrown or swung over to the full line position shown in Fig. 4, which will throw the yoke or rather the cross-bar 26 thereof, against the periphery of the fly-wheel and thus by gravity gently arrest further movement of the mechanism, the weight of the handle being sufiicient in itself to prevent further actuation of the mechanism. When it is desired to again permit the mechanism to operate, the handle 27 is thrown or swung to the dotted line position (Fig. 4) the handle will not be able to fall farther in this direction, because the yoke portion of the shaft 24 will lie flat against the bottom of the casing and thus prevent the handle from falling. Both in the on and off positions the brake is maintained in place by gravity.

What I claim is:

1. In a device as described, in combination, a casing, a pair of vertically-spaced apart walls secured upon the bottom thereof, a shaft journaled upon said walls, a fiywheel fixed upon said shaft, a rod bent into right angular form so as to provide a horizontal shaft and a vertically-operating arm, the horizontal shaft portion of said rod being journaled within said Wallsso as to rotatably rest upon the bottom of said casing, the intermediate portion of said rod being formed into a U-shape to provide a crank, the vertically operating arm of said rod projecting exteriorly of said casing, and a handle formed upon the outer end of said vertically operating arm, said crank being of such a length that it engages the periphery of said wheel and rests by gravityagainst the same.

2. In a device as described, in combination, a casing, shaft bearing Walls secured therein, a rotary shaft supported in said walls parallel to the bottom of said casing, a- U-shaped integral crank formed upon said horizontal shaft for rotating with said shaft, a fly-wheel, a shaft above the first shaft upon which said fiy-wheel is mounted, and a crook formed upon said horizontal shaft and engaging one of said walls to hold said first shaft against longitudinal displacement, said crank adapted to be wedged against the periphery of said fiy-wheel to hold the latter against movement. 7 Signed at New York city, N. Y., this 16th day of June, 1917.
