HARRY P. TOWNSEND, OF NEW BRITAIN, CONNECTICUT.

TOY.

To all whom it may concern:

Be it known that I, HARRY P. TOWNSEND, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented a new Toy, of which the following is a specification.

My invention relates to that class of toys in which there is a semblance of a race between moving objects, and the object of my invention is to provide a toy of this class in which it will be practically impossible to determine in advance which object will arrive at a predetermined point before other objects; and a further object of the invention is to provide a toy of this class in which the mechanism is self acting to vary and control the speeds of the different objects. One form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation of the mechanism inclosed within the case, one side wall of which is removed and the end walls are shown partially in section. Fig. 2 is a view in cross-section through said case, one side of which is broken off, the ends of a portion of the shafts being also broken off. Fig.

3 is a detail view in cross section through a portion of the case on a plane passing through the starting shaft.

In the accompanying drawings the numeral 1 denotes a case that may be constructed of any desirable material as wood or the like to inclose the operative parts of the mechanism. WVithin this case 1 a main driving shaft 2 is mounted, this shaft preferably extending crosswise of the case and being supported in the side parts thereof. Suitable means are provided for imparting to the shaft a primary movement, in the form shown a crank or handle 3 being secured to the shaft to serve this purpose. There are a number of moving objects having a relative movement to each other, and movement is imparted to these objects by mechanism connected with the main shaft, there being a separate mechanism for each object. For the purposes of brevity in description one of such mechanisms only will be described, it being understood that this description will apply equally to each or all of the mechanisms.

A primary driving sprocket 4 is mounted on, but having rotative movement inclependently of the shaft 2, in the form of de- Specifieation of Letters Patent.

vice shown this shaft in fact being mounted in a hub of the sprocket, which hub is mounted in the side walls of the case and has the crank 3 secured thereto outside of the case, as clearly shown in Fig. 2 of the drawings. A chain 5 extends from the primary driving sprocket 4 to a sprocket 6 located on and keyed to the starting shaft 7 this shaft being employed for the purpose of placing the objects in position to start from the same line. A pin 8 secured to the starting shaft encounters a stud 9 on the path support 10 which is mounted to rotate independently of the shaft 7, for purposes to be hereinafter described.

The handle 3 is primarily moved in the direction indicated by the arrow in Fig. 1 to place all of the objects 11 at the starting point and also to rotate the shaft 2 to tension the main spring 12. This main spring is located in a suitable case, one end of the spring being secured to the shaft 2 and its other end to a stationary support 13. By tensioning the main spring suflicient power is obtained to rotate the shaft 2 and the several mechanisms connected therewith to cause the objects 11 to move in the direction indicated by the arrow in Fig. 1.

A ratchet wheel 14 is keyed to the main shaft 2, and has a nose 15 that, in the turning movement of the ratchet wheel, encounters a pin 16 extending from the side of the sprocket wheel 4. The teeth 17 on the ratchet wheel 14 engage with a pawl 18 pivoted at the side of a gear 19 loosely mounted on the main shaft 2. This gear 19 meshes with a pinion 2O keyed to an intermediate shaft 21 mounted in shaft supports 22 secured to the bottom of the case. A pinion 23 is also keyed to the intermediate shaft 21, this pinion meshing with a pinion 24 mounted on a stud25 secured to the support 22. The pinion 24 is a double pinion, one set of teeth meshing with the pinion 23 and the other set meshing with the teeth of a gear 26 loosely mounted on the intermediate shaft 21. This gear 26 has ratchet teeth engaging with a pawl 27 pivoted to one, 28, of a number of path drivers. This path driver is in the form of a disk loosely mounted on the shaft 21, and there is a coacting path driver 29 keyed to the shaft 21. These path drivers are of peculiar con-- struction and are adapted to engage with and drive a path support 30 loosely mount-ed on a shaft 31. This path support has a neck 32 on which the path supporting sprocket 33 is loosely mounted and held in frictional engagement with the support as by means of a spring 34. The path support 30 has teeth 35 which are engaged by a holding pawl 36 to prevent movement of the shaft support in one direction.

When the objects are at or near that end of their travel shown in dotted outline in Fig. 1 a movement of the handle 3 downward and to the right will rotate the driving sprocket 4, and through the medium of the pin 16 and nose 15 the ratchet wheel 14 will be rotated, turning the shaft 2 to wind the spring 12. In this movement the ratchet travels away from the pawl 18 so that the other engaging parts at this end of the case are not moved. As the handle is turned the chain 5 is caused to travel rotating the starting shaft 7. This will cause the pin 8 appurtenant to that path support 10 containing the object farthest advanced to first come in contact with its stud 9 and start the object backward. The several pins 8 will successively engage the studs on those path supports having the object next in the I rear until the objects are brought into line and are all then simultaneously moved backward to the position shown in full lines in Fig. 1.

The path 37 is preferably in the form of a chain passing about the sprocket or path support 10 and the sprocket 33. The paths have lateral projections 38 engaging grooves 39 in the case for the purpose of preventing a sagging of the path and to cause it to travel in a direct line across the case. A spring 39 having one end secured to the case and the other to the chain 5 causes the parts to be turned to their normal position after the spring has been wound and the objects moved to the starting point.

A governor consisting of a disk 40 pivoted 1n the case and having teeth meshing with the teeth on the gear 19, and a pinion 41 having teeth meshing with the teeth on the disk 40 is employed for steadying the movement of the figures. A fan 42 is secured to rotate with the pinion 41, and a spring retained pawl 43 mounted on the case is adapted to engage this fan. A connecting rod 44 extends from the pawl and has a pin 45 overlying the path and in position to be encountered by the support 46 of the object. There being a governor appurtenant to the mechanism for each of the moving objects it will be noted that that object which first arrives at the stopping point will engage and operate the pawl appurtenant to its path, and the entire mechanisms will therefore be stopped with the objects in the relative position they occupied when the one in advance operated the stopping mechanism.

The path drivers are of peculiar construe tion, as best shown in Fig. 1, the peripheries or teeth being cut away at different portions of the circumference, these cut away portions being of greater or less extent as may be desired. The cutaway portions are differently formed on each of the drivers appurtenant to a certain path, and they are also differently formed on each of the drivers appurtenant to the different paths.

It will be noted that through the mechanism illustrated the driver 29 is rotated at a faster rate of speed, being connected directly to the shaft 21, than is the driver 28, the speed of which is reduced through the intermeshing train of gears. When the driver 29 is rotating the support 30 the driver 28 will be carried along with it. the pawl 27 moving freely over the teeth of the ratchet 26. WVhen, however, a cut away portion of the periphery of the driver 29 shall come opposite the support 30 and the periphery of the driver 28 shall be in engagement therewith then the support 30 will be driven at the slower rate of speed. If it shall happen that both of the drivers shall have a cut away portion located oppositethe driver 30 at the same time then the support 30 will be momentarily stopped. It will thus be seen that the difierent objects may be driven at different speeds and that the speeds of each will vary, and that by arranging the drivers with the cut away portions diiferently positioned in each of the drivers appurtenant to a single path, and also 1n the drivers appurtenant to the different paths, that it will be impossible to tell which object will first arrive at the stopping point. When the handle is turned to place the objects at the starting point it will be noted that the pawl 36 will hold the support 30 against movement, but owing to the loose connection between the sprocket 33 and the support, the path and sprocket are allowed to turn independently of said support.

Vhile I have shown herein an endless path as a means of supporting the objects my invention contemplates the use of paths of different form of construction which will convey the objects from a starting to a finishing point or goal and then replace the objects at the starting point for another trial. I also contemplate broadly any means by which the objects may have the same speed at the finishing point or goal as at the starting point, and for varying said speed in the travel of the object from the start to the finish; and my invention also contemplates any means for moving different objects between points located at the same distance apart during different intervals of time at different trials, each object at times being enabled to reach the finishing point before either of the others, and the mechanism being so constructed that it will be impossible to predetermine or select at any trial the object which will cover the distance in the shortest time.

The small arrows shown in Fig. 2 of the drawings indicate the direction of rotation of the shafts to move the objects forward.

While the path supports shown herein are not of a suflicient size to carry an object entirely across the case, yet it will be understood that in actual practice they will be made of a sufiicient size to accomplish this purpose.
