Specification of Letters Patent.

Patented June 20, M916- Application filed December 26, 1914. Serial No. 879,128.

To all whom it may concern:

Be it known that I, EDWARD S. SAVAGE, of I the city of Rochester, State of New York,

duced by the action of a spring or other motive power.

The object of the invention is to provide a simple method of controlling the motion in mechanical toys and to provide toys of this class which will be simple and cheap to manufacture and in which the motion will be continuous for a considerable length of time after winding.

Another object is to provide mechanical toys in which the motion is controlled within the toy itself without the use of the usual complex and more expensive train of gears the motion being retarded Without necessary contact of moving parts with an external body.

These objects I attain by the mechanism shown in the accompanying drawings, in which Figure 1 is a vertical section taken longitudinally and Fig. 2 a vertical section taken transversely, of one form of the invention.

Fig. 8 is a plan view and Fig. 4 a vertical section taken longitudinally, of another form of the invention.

Referring by numerals to the accompany,

ing drawings, 1 is the body portion. It may be made to represent a living creature, a

moving vehicle or any object having movable parts which may be simulated in a mechanical toy. In Fig. 1 and Fig. 2 the body is a sheet metal stamping in the form of a bug. To the body is attached the shaft 2 about which the cylinder 3 revolves. The cylinder 3 is closed at both ends by the caps 4: having center holes which serve as bearings. A wooden roller 5 is fitted tightly to the cylinder 3. A friction piece 6 fits tightly on the shaft 2 and has two arms 7 which extend parallel to the axis and close to but not in contact with the inner surface of the cylinder. The coiled spring 8 is attached at and at the other end to the cylinder or cylmder cap. The space within the cylinder surrounding the shaft, spring and friction plece is filled or partly filled with a semifiuid or viscous material, such as soft pitch or thick molasses. This viscous material sticks to the inner surface of the cylinder 3 and to the arms 7 of the friction piece causing a. resistance which effectually prevents rapid revolution of the cylinder and its roller 5 but permits the cylinder to turn slowly until the spring is completely unwound. The spring is wound by holding the toy in the hand and drawing it backward while pressing the roller against some surface such as a table or floor. In action, the rotation of the roller draws the toy forward slowly until the spring is unwound. Obviously the speed of motion depends upon the strength of the spring and the nature of the viscous substance used. This construction is illustrative of one embodiment of the broader features of my invention and I propose claiming it specifically in a separate application herefro-m.

Fig. 3 and Fig. 4 show another form of my invention in which the body 1 is a sheet metal stamping in imitation of a lizard. Motion is transmitted from the spring 8 to the shaft 2 the rotation of whichcauses the legs 10 and 11 to oscillate horizontally in opposite directions. The feet are provided with spurs 12 pointing backward which cause them to catch on a cloth surface when moving in a backward direction, but permits the feet to slide when moved forward. The end of the tail 13 serves as a key for winding the spring, and is provided with notches on its bearing surface which engage with beveled teeth lt permitting the key to be turned one direction only. The hook 15 turns with the key and. supports one end of a rubber band 8 which acts as the drive spring. The other end of the rubber band is attached to the hook 16 at one end of the shaft 2. The shaft 2 has an ofiset portion 17 which passes through the vertical slots 18 in a vertical portion of the leg members. The front legs are pivoted freely at the points 19 and the rear legs at the points 20. The shaft is provided near its forward end with another ofiset portion 6 which Serves the same purpose as the friction piece employed in the toy bug described above. The

V offset or friction portion 6 is inclosed within the cylinder 3 which is filled with a viscous material. In action, the viscous material clings to the inner surface of the cylinder and retards the motion .of the shaft 2, which,

turning slowly, causes the legs to oscillate l and if placed on a cloth surface the toy will travel forward, and as the motion 1800111 paratively slow it will be sustained for a considerable length of time.

I prefer to use a truly viscous material such as those mentioned, but it is obvious Chaps technically viscous but which would that there are equivalentmaterials not pergive. substantially the same results the function of'thiselement being to cling toor to yield. slowly before the action of the part to be retardedf Therefore, the fluid, of

whatever kind, should be of a tacky or sticky nature whereby'it offers this clinging resistance andls, at thesame time, too thick or heavy to readily leak out through the bearings of thecontaining member.
