STOP-MOTION FOR MECHANICAL TOYS.

SPECIFICATION forming part of Letters Patent No. 675,718, dated June 4, 1901. Application filed April 6, 1901. Serial No. 54,615. (No model.)

To 0035 ZU/LOWL it 'n'my concern:

Be it kn own that LATHERTON D. CONVERSE, acitizen of the United States,and a resident of TVinchendon, in the county of \Vorcester and State of Massachusetts, have invented a new and Improved Stop-Motion for Mechanical Toys, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a means for. automatically preventing the wheels or axles of a motor-controlled vehicle from turning until the vehicle is placed upon the support upon which it is to travel.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a vehicle to which the improvement is applied, the axles being shown in section and the driving-axle and its wheels held against turning. Fig. 2 is aviewsimilar to Fig. 1, the motor, however, being shown as unchecked; and Fig. 3 is a rear elevation of the vehicle and attachment.

The wagon-bodyA (shownin the drawings) may be of any desired construction, and itis provided with a driving-axle 10, held to turn only in hangers or pedestals 11, which are usually attached to the body. The body is further provided witha second axle 12, and this second axle 12 has rotary and vertical movement in slots 13, produced in hangers or pedestals 14., secured to the body. The drivingaxle 10 is provided with wheels 10, secured thereto, and the vertioally-movable axle 12 is provided with attached wheels 12. A motor B, preferably a springunotor, is used in connection with the driving-axle 10, and the frame of this spring-motor is connected at one end by a hanger 15 with the bottom portion ofithe vehicle-body A, while the other end of lhe frame of the motor is loosely supported on the driving-axle 10. One of the gears 16 of the motor is shown in engagement with a pinion 17, attached to the driving-axle 10, as is best illustrated in Fig. 3.

A ratchet-wheel 18 is secured to the axle 10; but instead of this ratchet-wheel one or more projections may be carried upon the d riving-axle. In connection with the ratchetwheel 18 or its equivalent a stop-lever 19 is employed. This stop-lever is fulcrumed between its ends upon a hanger 20, which is usually attached to the bottom of the vehiclebody, as is shown in Figs. 1 and 2, and at one end of the stop-lever 19 a longitudinal slot 21 is produced, which receives the verti-- cally-movable axle 12, while at the opposite end of the said stop-lever a head 22 is formed, adapted in one position for engagement with the teeth of the ratohet wheel 18 or with the projections from the driving-axle when such project-ions are used.

In operation when the vehicle is lifted from the support upon which it is designed to travel the axle 12 will drop to the bottom portion of the slot 13 and the head 22 of the stop-lever 19 will be carried upward and will engage with a tooth of the ratchet-Wheel 18 or the projection on the axle 10, thus preventing the driving-axle and the wheels connected therewith from turning and enabling the motor to be safely wound up without loss of power. The moment, however, the vehicle is placed upon a support the wheels 12, connected with the vertically-movable axle 12, will cause the said axle to move upward in the slot 13, and thus carry the head 22 of the stop-lever from out of engagement with the tooth of the ratchet-wheel or the projection on the axle 10, with which it was in contact, permitting the motor to immediately exercise its full power on the driving-axle 10.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In mechanical toys, a vehicle, amotorcontrolled driving-axle and its wheels, a second axle and its wheels, and a check for the motor, controlled by the movement of the second axle.

2. In a mechanical toy, a drivingaxle, a motor in operative connection with said driving-axle, a projection from the driving-axle, a second axle mounted to turn and slide, and a check device operated by the second axle and arranged for contact with the projection from the driving-axle.

3. In a mechanical toy, a motor-controlled driving-axle and its wheels and a second axle and its wheels,thesecond axle being mounted name to this specification in the presence of to turn and to slide vertically, a lever having two subscribing witnesses.

a slidin connection with the second axle, and an GXtGESiOII from the said lever, adapted for A FHERTON CONVERSE 5 engagement with the projection from the Vitnesses:

driving-axle, as described. J. FRED. AOKER, In testimony whereof I have signed my JNO. M. BITTER.
