SPRING-ACTUATED TOY.

Specification of Letters Patent.

Patented June 10, 1913.

Application filed December 7, 1911. Serial No. 664,311.

To all whom/ 2'25 may concern Be it known that I, DAVID P. CLARK, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Spring-Actu-- ated Toys, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to spring-actuated toys and more particularly to locomotive toys of this type. i

The object of the invention is to provide a toy of this character in which the spring v is a side elevation of-a toy embodying my invention; Fig. 2 is a longitudinal section, taken through the rear portion of such a toy, showing the gearing in elevation; Fig. 3 is a horizontal section taken immediately above the gearing; Fig. 4 is a section taken on the line a m of Fig. 2; and Fig. 5 is a section taken on the line y y of Fig. 2.

In these drawings I have illustrated one embodiment of my invention and, for the purpose of this illustration, have shown the invention as applied to -a toy, the body 1 of which is formed in imitation of an automobile touring car. The forward portion of thisbody is supported by steerin wheels 2, of the usual construction, and t e rear portion of the body is supported by propelling wheels 3 mounted on an axle 4 rotatably supported by the body. In the present instance this axle is journaled in supplemental side members 5 constituting a frame which supports the several active parts of the device. Obviously, however, this supplemental frame could be omitted and the parts mounted directly in the side walls of the toy, where these have sufficient rigidity. Rotatably mounted in the frame members 5 parallel with the axle 4,- and preferably in front thereof, is a shaft 6 having rigidly secured thereto at one end thereof a gear 7 This gear meshes with a pinion 8V loosely mounted on a stud 9 carried by one'of the side members of the frame a and is rigidly secured to and rotates with a gear 10 also loosely mounted on the stud 9 and meshing with a pinion 11 on the axle 4. It will be apparent that the ratio of this gearlng is such that motion will be transmitted from the shaft 6 to the axle 4 at an increased speed and will be transmitted from the axle 4 to the shaft 6 at a decreased speed. Coiled about the shaft 6 is a spring 12 having one end rigidly secured thereto, preferably by connecting the same to a plate 13 rigidly secured to the shaft. The other end of the spring 12 is connected to a ratchet wheel 14 which is loosely mounted on the shaft 6 and has secured thereto and rotating therewith a pinion 15 also loosely mounted on the shaft (5. A spring-pressed pawl 16 mounted on the frame 5 engages the teeth of the ratchet wheel 14 and holds the same against rotation in one direction, namely, in the direction in which the expansion of the spring would tend to move it. The pinion 15 which is secured to the ratchet wheel -14 meshes with a gear 17 loosely mounted, on the stud 9 and correspending in diantetier and the number of its teeth to the gear 10 which is also mounted on that stud.

.In order that the spring may be wound from the axle, by a comparatively few rotations'lzfof the latter, and that the expansion of, the spring will impart a large number of rotations to the axle we have provided means for connecting together the gears 10 and 17, thereby causing the ratchet 14 to be rotated by the rotation of the axle 4. The ratio of the gear 17 and the pinion 15 is such that the ratchet wheel, to which one end of the spring is connected, will be rotated at a much higher rate of speed than that at which the gears 10 and 17 are rotated, and, on the other hand, the ratio of the gear 10, pinion 8 and gear 7 is such that the shaft (3 to which the other end of the spring is connected will be rotated at a rate be compressed owing to the more rapid rotation of the ratchet wheel. v The connection between the gears 10 and- 17 may be made in any suitable manner. In these drawings 1 have illustrated one convenicnt method for forming this connection.

As here shown a pinion 18 of a width suflicient to engage both the gears 10. and 17 simultaneously is movably supported adjacent to the'gears and means provided for moving this pinion into and out of engagement with the gears, thereby making and breaking the connection between'the same. Preferably, the pinion 18 is rotatably mounted in a pivoted frame 19 hung on a stud 20 carried by the supporting frame 5. Movement may be imparted to the frame 19 and pinion 18 by any suitable means. As here shown this is accomplished by means 20 of a rod 21 pivotally connected to the frame 19 and extending forwardly therefrom to a point near the drivers seat, where it is connected with a lever 22. The manipulation of this lever will move the pinion into and out of engagement with the gears and the location of the lever is not only a convenient one but it places the lever in the same position occupied by the controlling lever of an automobile, thus adding to the toy an additional feature and one that is very attractive in the eyes of a child. The lever 21 is pref erably provided with a notch 23 arranged to engage a stud 24 and limit the rearward movement of the frame 19 and pinion 18. In the operation of a self propelled toy equipped with the invention'the pinion 18 is moved into mesh with the gears 10 and 17 and the axle 4 is rotated by moving the toy over the floor a few times in a forward direction. This motion is transmitted through the pinion 11 to the gears 10 and 17 and from these gears the motion is transmitted at increasing and decreasing speeds, respectively, to the gear 7 and ratchet wheel 14. Inasmuch as one end of the spring is connected with the gear, through themedium of the shaft 6, and the other end of the spring is connected with the operating wheel it will be obvious that the more rapid rotation of the ratchet wheel 7 will cause the spring to be compressed. The pawl 16 holds the ratchet wheel against movement under the influence of the spring and so long as the pinion 18 is in mesh with the gears 10 and 17 the shaft will likewise be held against movement under the tension of the spring. When it is desired to propel the toy over the floor the lever 22 is thrown forward to move the pinion out of engagement with the gears. This releases the shaft from the pawl 16 and it is freeto rotate under the influence of the spring.- This rotation of the shaft is transmitted through the gear 7, pinion 8 and gear 10to the pinion 11 on the axle a, and, owing to theratioof the gears,

oeaeae the axle 4 is rotated at a much higher rate of speed than is the shaft 6 and consequently the expansion of the spring will impart to the axle a number of rotations many times greater than the number required to com press the spring. In addition to the very material advantage of being able to compress the spring by a few short movements of the propelling wheels over the floor and to secure from this compression a long movement of the toy and the simplicity of the whole mechanism, the invention possesses another very decided advantage, namely, that it is practically impossible to wind the spring so tight as to break it, this resulting from the fact that the compression is secured through the frictional engagement of the propelling wheels with the floor and before the spring'is wound tight enough to injure the same the wheels will'slip over the floor. 5

While I have illustrated one embodiment of the invention and have shown the same as applied to a self-propelled toy it will be apparent that the invention is not necessarily limited to toys of this type and that 0 by substituting other devices for the propelling wheels on the axle l and thereby transforming this axle into a shaft, the invention! may be applied to stationary toyswithout other change. Further it will be apparent 5 I that various alterations may be made in the mechanism herein shown and described without departing from the principle of the invention and I therefore Wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
