TED sr THOMAS M. VAUGHAN, OF BATTLE CREEK, MICHIGAN, ASSIGN'OR T0 AMERICAN FLYEB MANUFACTURING COMPANY, A CORPORATION 7 OF ILLINOIS.

MECHANICAL TOY.

Specification of Letters Patent.

Patented'May 28, 1918.

Application filed May 5, 1917. Serial No. 166,579.

To all whom it may concern:

Be it known that I, THOMAS M. VAUGHAN, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Mechanical Toys, of which the following is a spec1- fication.

The present invention has to do with certain improvements in mechanical toys and more particularly it has to do with a toy having the form of a climbing bear whlch is adapted to climb a string when the string is pulled.

Other objects and uses of the invention will appear from a detailed description of the same which consists in the features of construction and combinations of parts hereinafter described and claimed.

Referring to the drawing:

Figure 1 shows in side elevation the construction of the toy;

Fig. 2 shows a fragmentary longitudinal section through the operating mechanism;

Fig. 3 shows a front elevation of thetoy; and.

Fig. 1 shows a section taken on the line 44 of Fig.2, looking in the directionv of the arrows.

body of the toy comprises a block of wood 5 cut into suitable form to represent the body and head of the animal. This block of wood has a forwardly extending recess 6 within which are mounted the main operativeparts of the toy. The central portion of the body block is covered over or protected by a U-shaped casing or the like 7, the, sides of which provide side walls 8 and 9, and inclose the recess or opening 6. Within thisrecess there is mounted a double or differential pulley, the detailed construction of which is well shown in Figs. 2 and 4:. The construction therein illustrated comprises a central core or the like 10 having two portions of different diameters according to the difierential action to be secured. A central plate 11 is seated against the step of the core and is held in place by frictional engagement with the smaller portion of the core. Circular side plates 12 and 13 are also provided against the ends of the core.

The central portion of the core is cut out and a tubular sleeve 14 is driven through the same. The ends 15 and 16 of this tubular sleeve are then flanged or headed down against the plates 12 and 13 so as to look the same firmly against the wooden core. In this way, the differential pulley is built up, and a pulley so constructed may be made of comparatively narrow dimensions, because of the thinness of the plates 11, 12, and 13. A plug 17 may be driven into the tubular sleeve 1 1, and a bearing pin 18 may be driven through the plug 17. This journal bearing pin finds bearings in the side walls 8 and 9 of the body portion.

A cord 19 has its inner end secured to the smaller portion of the differential pulley, and it passesout from the body portion through a hole 20, as shownin Fig. 8. A cord 21 has its inner end fastened to the section of larger diameter and passes out through a hole 22. of the body portion. The cords 19 and 21 are so wound on their re speotive portions of the differential pulley that, upon exerting a pull between said cords, there will be a tendency for the figure to rise along the cords, assuming that the cord 19 is uppermost, as is shownin the direction of rotation of the differential pulley and will thus insure a winding of the cord 19 onto the smaller portion of the pulley, thus making the figure rise in the manner previously explained.

It will sometimes be desirable to make use of the rotation of the differential pulley for the purpose of bringing into action a supplementary element located on the outside of the body portion, so as to give greater realism to the action, or so as to mystify the observer. In the present case, I have availed myself of the rotation of the differential pulley for the purpose of actuating the legs of the figure, so that the same will appear to climb along the cord.

In the construction illustrated, the lower legs comprise the upper joint sections and 24; pivoted to the body portion at the point 25. The lower leg sections 26 and 27 comprise the arms of a U-shaped member, the cord 21 being extended through the connection between said arms. manner the plates 28 and 29. constitute the upper sections of the front legs, the fore arm sections of said legs being formed by the arms 30 and 81 of another ll-shaped plate. The cord 19 is extended through the connection between the arms 30 and 31. All of the legs are pivoted to the body portion, and this pivoting is easilv, accomplished by reason of the fact that the core of the. body portion is made'of wood or similar material.

In order to actuate the front and hind legs, I have availed myself of therotation of the difierential pulley. For this purpose, I have provided a crank 32 on the pin 18, and I connect said crank to the upper and lower leg sections 28 and 23 by the links 83 and 34:. Owing to the fact that the front legs are joined together by a U-shaped member, and to the fact that the hind legs are also joined together by another U-shaped member, it follows that a single crank and a single set of links is sufiicient to actuate all of the legs.

As a simple means of joining the inner ends of the cords l9 and 20 to the core of the difierential pulley, I have shown said core as provided with transverse openings or holes 35 shown more in detail in Fig. a, through which the cords are passed in order to fasten their inner ends to the core.

While I have herein shown and described only a single embodiment of the features of my invention, still it will be understood that I do not limit myself to the said embodiment, except as I may do so in the claims.

l claim:

1. As a new article of manufacture, a me chanical toy comprising a wooden body portion having a forwardly extending recess in its central portion, a U-shaped sheet metal plate enveloping the body portion and covering over said recess, a pin extending through the recess and journaled in the arms of the lJ-shaped plate, one of the protruding ends of said pin being provided with a crank, a differential pulley mounted on and secured to the central portion of the pin and within the recess, a. pair of cords diii'erentially wound on the two portions of said pulley, one of said cords passing,- upward from the smaller portion of the pulley and In the same:

outward through the body portion, and the other cord passing downward from the larger portion of the pulley and out through the body portion, suitable limbs pivoted to the body portion, and link connections from the crank to said limbs, substantially as described.

2. As a new article of manufacture, a me chanical toy comprising a. hollow body portion having suitable side walls, a pin ex.- tending through the hollow portion of the body and journaled in said side walls, a crank on a protruding end of said pin, a differential pulley mounted on and secured to the pin within the body portion, a pair of cords difierentially wound on the two portions of said pulley, one of the cords passing from, the smaller portion'of the pulley and upwardly and outthrough the body portion, andthe other cord passing from the larger portion of the pulley and downwardly and out from the body portion,

suitable limbs pivoted to the body portion, and link connections lying outside of the body portion and extending from the crank to said limbs, substantially as described.

3. As a new article of manufacture, a me ohanical toy comprising a hollow body portion, a pin extending through said body portion and journaled in the walls thereof, a crank on a protruding end of said pin, a suitable element lying outside of the body portion and operatively connected to said crank, a differential pulley on the pin within the body portion, a pair of cords differentially wound on the two portions of said pulley, one of said cords passing from the smaller portion of the pulley upwardly and out throughthe body portion, and the other of said cords passing from the larger portion of the pulley downwardly and out through the bodyportion, substantially as described.

As a new article of manufacture, a mechanical toy comprising a hollow shell, a transverse pin therein, a difierential pulley mounted on said pin, said pulley comprise ing a central fibrous core having two portlons of imequal diameters concentr1cally formed, and having side plates and an interinediate partition, and a pair of cords difierentially wound on the two portions of the pulley, one of said cords passing from the smaller portion of the pulley upwardly and out through the shell, and the other cord passing from the larger portion of the pulley downwardly and out from the shell,

substantially as described,
