Tor swmomo CRANE Ira I andree, ontonagon, Mich.

My invention relates to cranes, and more partlcularly to a toy swinging crane employing a log' grapple, sand bucket or other pickup'device adapted to be opened or closed at will, raised and lowered 'o'r' swung to either side, as a useful, amusing and instructive mechanical toy: for use by children.

The object of the invention is to provide a toy swinging crane on which the child isadapted to be seated and provided with controlling means or levers for raising or lowering the log grapple, sand bucket or other pickup device, and to open and close the same as well as provided with foot operative' means constituting rests for: the feet of the child, when seated on the body of'the device, so as' to swing or turn the same in substantially thesame way that a steam shovel, dredge or crane is operated, so as to provide an amusing, instructive and mechanical device by which a child may move small logs, snow, sand and the like While furnishing pleasure and enjoyment the same as or in imitation of a full sized crane. "Another object of the invention is to provide a toy swinging crane, which is constructed in a simple and economical way, to give substantially all of the operative movements of a full sized crane, and which is strong, rugged and simple and practical to operate by a child.

Other objects and advantages reside in the details of; construction and operation as more Figure 1 is a side elevation of a toy-swinging crane in accordance with the invention;

3 Claims; (CL 212-44) able frame or base Iii in the form of a skid or sled having runners. I I, but may be a wheeled frame or otherwise. A rectangular or other shaped body I2 inbox or like form, is shown mounted to turn onl the base ID, as by means of an anti-friction bearing or turntable I3 having circular or other bearing members I4, which are in the form of disks, spacing the bottom of the body indicated at I'5,-from the top or platform I6 of the base I0 and bolted through the same, as indicated at H to constitute a vertical pivot axis as well as connecting said parts in assembled relation. Mounted on the rear end of the body I2, is a seat-I8, which projects from the opposite sides of the body and may have rounded ends, as shown, to prevent injury due to sharp corners. A boom I9 extends upwardly and forwardly in an inclined position from the front of the body [2 and an extension of the bottom I5 thereof and comprises upwardly converging side members or boom arms or bars. 2| suitably secured to the body rigid therewith, and connected at their outer and upper ends by a transverse horizontal shaft, rung or rod 22 fixed in position to rotatably support a pair of pulleys 23 and 24 thereon in spaced relation.

A pair of pulleys 25 and 26 are also supported by the boom IS on the arms or bars ZI at points below the center of lengths thereof, as by means of bearing brackets 21 and a pair of levers 28 and 29 are pivoted on a horizontal pivot 30, within the body l2 and extend upwardly and are movable through a pair of spaced parallel longitudinal slots 3| and 32 in the top 33 0f the body I2 to swing back and forth therein *when operated manually, gripping the handles 34 thereof by the child or operator reposed on the seatv I8. i

A line, cord or cable 35 is connected to the lever 28 between its ends, preferably adjacent the top 33 of the body I2 as by means of a screw eye or the like 36 and extends under, around in front of and over the pulley 25, after which it is extended under and around a pulley 31 attached by a bearing bracket 38 to the same lever 28 near the upper end or handle 34 thereof above the point of attachment 36 of the cable 35 with said lever at a lowerpoint. The cable then extends up over and around the pill ley 23 which turns on the shaft 22 connectin the arms 2| of the boom I9 and downwardly to the upper end of a plate 33' which is centrally apertured for mounting it; on the cross rod 39 of a pickup device such as a log grapple, sand bucket or the like 40; Pairs of downwardly divergent arms or links 41 are pivoted at their upper ends to the end portions of the rod 39 and pivotally connected at their lower ends, as indicated at 42, to pivot ears 43 fixed to the opposite edges of two semi-circular sheet metal or like grapple or bucket sections 44 as seen in Figures 3 and 6. These sections 44 are hinged together at their upper edges as indicated at 45 and the lower edges are free to separate or move to open position and adapted to close in abutting relation when swung toward each other normally by their Weight or gravity.

Another cable 49 is connected to the lever 29 as by means of a screw eye or the like 41, Sim:-

ilar to the connection 35 of the cable 35 to the lever 28 and extends forwardly and under, around and over the pulley 26 carried by the nects the upper end of the boom to the upright other boom arm 2!, after which it is extended rearwardly under and around a pulley 48 mounted in a bearing bracket 49 on the lever 29 above the eye ,4! and in the same manner asthe pulley bearing bracket 38 is mounted on the lever 28. The cable 46 then extends forwardly over and around the pulley 24 and downwardly under and around" the pulley 50 mounted. on the pivot pin or pintle 5| of the hinge 45 at the center of the length, thereof and of the pick-up device at the jaws or sections 44 in a slot formed by a pair of alined recesses 52 formed in the hinged edges of the grapple or bucket sections or halves 44. From pulley 50, cable extends upwardly and attaches to plate 38.

By swinging both of the levers 28 and 29 rear- Wardly, the pickup device 40 may be raised, and by swinging both of said levers forwardly, said pickup device may be lowered. Also, by swinging only the lever 29 rearwardly the pickup device will be closed, and by swinging only said lever 29 forwardly the pickup device will be .al-

lowed to open. Obviously, the pickup device may be allowed to open before lowering it, and said device may be closed after lowering it. The ears 43 of each section 44 may be connected by a rod 53. i In order to swing the boom together with the body, to the right or left, that is to one side or the other, the forward extension 29 at the bottom of the body, has a foot or cross lever 54 pivoted intermediately thereon, as indicated at 55 and the ends of the foot lever are recessed as indicated at 56, to accommodate the feet of the child or operator sitting astrideof the toy on the seat l8, with one foot on each side of the foot lever near the ends thereof. Cables 5'! are connected to the ends of the foot lever 54 and are extended rearwardly along the sides of the body l2 and around pulleys 58 journalled or rotatably mounted as at 59, on the sides of the body near the back or rear end thereof and also close to but in spaced relation to the bottom-l5. These cables then extend downwardly and forwardly in an inclined position where they are anchored to the sides or runners H of the base or transporting frame ID as indicated at 60, and shown connected to the skids or runners H preferably substantially beneath the turn table or pivot l3, l4 and H or at any other suitable place. Thus, by pressing on the foot lever 54 with one foot, the boom and body are swung to one side and by pressing on the other end of the foot lever the boom and body are. swung on the pivot axis or turn table to the other side. In order to hold the pickup device in position, a cable 6! is fastened thereto at one end, as indicated at 52, adjacent one end at the pivot or hinge 45 f the sections 44 and 64, which corresponds to a dashboard or instrument board in front ofthe levers 28 and 29 and the operator in the manner of a fender, to help support the boom 19 in connection with the anchoring of the lower ends of the bars 2| to the body [2 and bottom I5 thereof adjacent the extension 20 or front end of the body. Obviously, the device maybe used by a child, for loading and unloading small logs or other articles in piles, or for efliciently shoveling or digging sand, dirt, snow or the like or small stones,

or gravel and raising and dumping the same to either side inpiles, thus providing an amusing, instructive and useful mechanical toy operated entirely manually by the child operator reposed on the seat of the body. 7

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from thespirit andscope of the invention as claimed.

I claim:

1.
