5 Claims.

vide a toy of the type indicated which will be entertaining and instructive and at the same time durable, cheap and accessible as to its operating parts. I

Other and more limited objects will become apparent from the following description when taken in connection with the accompanying drawings in which Fig. 1 is a side elevation, partly in section; Fig. 2 is a fragmentary plan view drawn to a larger scale; Fig. 3 is a rear elevation; and Fig. 4 is a ldetail of the extremity of the crane member.

Referring now to the drawings, the numeral I0 indicates a base upon which is mounted a body indicated generally by the numeral II and which carries a crane member I2 from which is suspended an electric lifting magnet I3.

The base I0 is comprised of a hollow stamping having a fiat central portion merging into a flange I4. Attached to the upper surface of the base I0, as by screws I5, is a gear member I6 having in its upper surface a ball race adapted to receive ball bearing members I l. Passing through the base I0 and centrally through the gear means I6 is a shouldered screw I8.

'I'he body II comprises in this embodiment a casting indicated generally by the numeral I9,

together with the various mechanisms mounted thereon including ,a top or casing 2li. The casting I8 consists of a floor 2l, upright side walls 22 and a transverse wall or web 23 joining the side walls 22 and positioned forwardly of the rear end of the floor 2i. The floor 2l is provided with a threaded opening adapted to receive the threaded end 24 of the screw I8, the shoulder of the screw I8 being adapted to abut the bottom of the oor 2l to limit the upward travel thereof so as not to bind or clamp the floor tightly against the gear means I6. The oor 2l is provided with a complementary ball race for the ball bearing members I1. Journaled in the side walls 22 are a power shaft 25, a crane operating drum shaft 26 and a magnet operating drum shaft 21. The power shaft 25 is driven from an electric motor 28 mounted on the transverse wall 23 by bolts 26 extending through said motor and said wall and operatively connected with said shaft through the medium of a worm 30 carried by the end of the motor armature shaft and a worm gear 3i with which said worm meshes and which is :dxedly connected to said power shaft.

Rotatably mounted loosely on the power shaft 25 are two pairs of opposed gears indicated by numerals 32 and 3'3 and numerals 34 and 35, respectively. Each of these gears carries a clutch element. Between the gears of each pair are clutch elements 36 and 3l, respectively, which are slidably but non-rotatablyconnected to the power shaft 25. Constantly meshing with both the gears 32 and 33 is a pinion 38 connected to 10 a shaft 39 which is journaled in suitable bearings and which drives the magnet controlling winding drum shaft 21 through the medium of a worm 40 and worm gear 4I. The clutch element 36 is controlled by a lever 42 pivotally mounted 15 on the bottom of the transverse wall 23 and having a terminal portion 43 extending to the outside of the body member I I through a suitable opening 44 provided with positioning notches at neutral position and at the two operating po- 20 sitions. From this it will be obvious that a mechanism has been provided whereby the magnet may be raised and lowered by reversing the direction of rotation of the drum 45 carried by the shaft 21 and upon which is wound the cable 25 46 which passes over the pulley 4l on the crane member I2 and through the pulley block 48 and is connected to the crane member I2 by the ring 48. Meshing with the gears 34 and 35 is a large gear 56 connected to a shaft which is journaled in a boss 5I on the floor 2| and carries a pinion 52 positioned below the oor 2I and meshing with the gear I6. The clutch element 81 is operated by a lever 53 similar to that 42 and pivotally connected to the bottom of the transverse wall 23 by a pin 54 passing through a spring 55 and the flange 56 at the bottom of said wall. This lever has its extremity extending to the outside of the housing 20 through a suitable opening 56 similar to that 44. From the foregoing, it will be seen that'by manipulation of the lever 53, the body and crane member may be swung about the screw I8 in either direction.

For the purpose of raising and lowering the 45 'crane member I2 that is causing it to pivot about the point 50, I provide a winding drum 58 carried by the shaft 26 and operated by a hand crank 58 through the medium of a shaft 60, a

worm 6I and a worm gear 62. Wound vupon the 50 is the electric lifting t I3 supplied with 55 electric current through the cable Si which drives its current from a transformer 61 mounted upon the iioor 2|. It should be noted that` substantially all the mechanism, especially the motor 28 and transformer 61, is mounted at the rear of the body for counterbalancing effect. By reference to Fig. 4, it will be seen that the pulleys 41 :and il are staggered to avoid interference of the cables with one another. The motor and transformer are supplied with house current by a suitable extenslon cord 68. A sight opening 69 may be provided in the top of the housing 20 for enabling a child to View the mechanism; or a transparent insert or complete transparent top may be provided for this purpose.

The lifting magnet employed is preferably of the construction shown in my copcnding application Serial No. 600,939, led March 24, 1932, of which this is a division.

In view of the foregoing, it will be clear that I have provided a device which is well adapted for its intended purposes and while I have shown and described a preferred embodiment, I wish it understood that I am limited only in accordance with the appended claims and the prior art.

Having thus described my invention, what I -claim is:
