ELMEQ F. MOQEY Patented Sept. 18, 1951 UNITED STATES PATENT OFF-ICE TOYJACK Elmer Morey, Riverside, Galif. Application April '5, 1949,-Serial No. 85,689

This invention relates to a toy, and more particularly to a "novel toy jack.

It is an object of this invention to providea toy jack of the kind to be more particularly described hereinafter which may be formed of only those essential parts operatively connected together to form a toy operable. substantially in the manner of a large, powerful lifting jack used for lifting automobiles and other heavy equipment.

Another object of this invention is to provide a toy jack of this kind whichmay be formed of any suitable material, the particular use or simulated .use, determining the strength or size of the material from which it is to be made.

Yet another object of this invention is to provide a toy jack of this kind which may be readily formed and assembled at an economical cost to be distributed at a low price in the market of small toys and the like.

'With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is aside elevation of a toy jack constructed according to an embodiment of my invention; I

Figure 2 is a top plan view thereof;

Figure 3 is an end elevation;

Figure 4 is .alongitudinal section taken on the line 1-4 of Figure 2;

, Figure 5 is a transverse section taken on the line 5-5 of Figure 1.

Referring to the drawings, the numeral 10 designates generally a toy jack constructed according to an embodiment of my invention. The jack I is formed to simulate the type .of lifting jacks used for raising automobiles, and other heavy equipment, and the jack in, being a toy, may be formed of any suitable material, as metal, plastic or the like.

The jack I0 is formed of a basemember H which is formed in the manner of a channel having a bottom wall [2, a rear wall I4, and a pair of side walls l and I6. The rear wall I4 extends perpendicularly from the extreme rear end of the bottom wall l2, while the side walls [5 and I6 extend forwardly from the side edges of the rear wall l4 and extends upwardly along the longitudinal side edges of the bottom wall I2. The side walls l5 and "5 are substantially triangular in configuration, being inclined downwardly and forwardly from the rear wall l4 and terminating at the extreme forward end of the 3 Claims. .(ol; 254-8) bottom .wall 12. The top edges of the side walls I 5 and 16 decline downwardly from the rear wall M, .beinginclined along the length of the base member. The rear wall [4 is formed with an opening 1 '1 intermediate the vertical height'thereof through which a crank or screw element [8 is adapted to be rotatably engaged, in a manner to .be more particularly described hereinafter.

The side walls [5 and i6 are further formed with outwardly-extending lugs or projections I9 which simulate the pivot pins or projections of the conventional large-sized jacks, to present a lifelike appearance for the toy article. Wheels 2i)v may be carried by the base member II at the ends thereof to provide the appearance of a portable or movable jack of this type. The wheels 20 may be supported-on axles 21 which are carried by the base member I I or the wheels 20 may be formed integrally with or fixed on the base member H in an immovable manner to merely present the appearance of wheels.

A lifting lever 22 issuperimposed upon the bottom wall l2 adjacent to and spaced from the nut element 28 and is connected adjacent one end to the side walls 15 and i6 for rocking movement about an axis transversely of the side walls. Specifically, the lever 22 is pivotally mounted within the base member II by being pivotally engaged with the rear ends of the side walls l5 and lb. The lifting lever 22 is formed of a length of flat metal, or other suitable material, bent upon its length to the desired configuration. Preferably, the lever 22 is formed with a longitudinally-extending lever arm or lifting arm 24, which is adapted to be extended along the length of the base member H. .A depending arm 25 is fixed to or preferably formed integrally with therear end of the lifting arm 24 and extends downwardly within the base member H. Outwardly-extending hinge or pivot pins 26 are formed integrally with the longitudinally-extending lifting .bar 24 adjacent the rear end thereof slightly forwardly of the connection of th horizontally-extending lifting bar with the vertically-extending lever arm 25. The pivot pins 26 are adapted to be rotatably extended through openings 21 formed in the opposite side walls l5 and I S adjacent the rear,.enlarged ends thereof. The openings 21 are formed adjacent the top edges of the side walls and the pins 26 are loosely engaged therein.

A nut element 28 is fixed within the base member ll adjacent the rear end thereof. The nut element 2-8 is formed of a transverse plate fixed between the side walls It and It a slight distance forwardly from the rear wall H. The plate 28 is preferably formed of such a thickness that the threads of the screw element I 8 may be engaged through an opening 29 near the bottom end of the plate 28 without the addition of a separate nut to be carried by the side walls of the plate.

A screw element I8 is slidably and rotatably engaged through the opening I! in the rear wall ll of the base member II, and is threadably engaged in the intermediate wall or plate 28. The screw element I8 is formed in the manner of a crank having a longitudinally-extending threaded forward screw portion 30 rotatably en: gaged in the rear wall I 4 and nut element 28, and a crank handle portion 31 extending rearwardly on the rear side of the rear plate 14. The

forward end of the screw element I8 is adapted to frictionally engage the rear side of the depending lever arm 25 to effect the pivoting movement of the lever 22 within the base member H.

,In the use and operation of the toy jack l0, with the lifting lever 24 pivoted between the side walls l5 and I6, the threaded screw element l8 engaging through the nut plate 28 and rear wall M will engage the depending lever arm 25 for lifting the forward end of the lifting bar 24 upon rotation of the screw element l8 to effect the forward movement within the body or base member I]. Upon threading of the screw element [-8 for longitudinal movement rearwardly in the base member, H, the weight of the forwardly-extending lifting bar 24 will effect the pivoted movement of the lever 22 in a manner to lower the extreme forward end of the lifting bar 24. For further increasing this gravitational return movementof th lever 22 to its initial substantially enclosed position within the base member II, a lifting pad 32 is fixed to or formed on the extreme forward end of the lifting arm 24. The lifting pad 32 simulates the lifting pad on conventional types of jacks which are adapted to be engaged with that portion of the member which is engaged by the jack.

I do notmean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

I claim:

1. A lifting toy jack comprising a bottom wall, a pair of spaced side walls positioned upon said bottom wall and secured to the latter, an end wall positioned intermediate said side walls ad- J'acent one end of said bottom wall and secured to said bottom and side walls, an upstanding nut element positioned inwardly of and in parallel spaced relation with respect to said end wall and fixedly secured to said bottom and side walls, a longitudinally extending lifting lever superimposed upon said bottom wall adjacent to and spaced from said nut element and connected adjacent one end to said side walls for rocking movement about an axis transverse of said side walls, said lever embodying a longitudinally extending arm and second arm positioned adjacent said one end of said first-named arm and dependingly secured to the latter, an element rotatably supported in said end wall and said nut element and having one end engageable with said second arm of said lever, and hand actuable means on the other end of said element for effecting the rotation of said element to thereby cause the rocking movement of said lever.
