TOY HOISTING CRANE.

Application filed May 26, 1928.

This invention relates to new and useful improvements in toys and aims to provide a toy that is generally constrilcted to simulate a hoisting machine that will by reason of its mechanical aspects prove interesting and amusing to children, especially those having mechanical inclination. Furthermore, the toy is so constructed as to be durable as well as useful in the lifting of small objects, while a child is playing with the machine, the invention further exhibitingr or `deinonstrating to the children a practical illustration oi' the crane hoist system and the use of pulle In the drawings wherein like reference characters indicate correspondingr parts throughout the several views:

Figure 1 is a side `elevation of my improved toy hoisting frame.

Figure 2 is a. horizontal section taken substantially upon the line 2-2 of Figure 1 looking' downwardly.

Figures 3 and 4 are detail vertical and diagonal sections taken.substantially upon the lines 3 3 and 4 4 o1 the same ligure, and` j Figure 5 is a sectional view taken on the line 5 5 of Figure 1.

Now having particular reference to the drawing, the invention consists of a horizontal frame 5 ot' suitable construction equipped at one end with a pivotal axle 6 to which i-s attached a tongue 7 and at its opposite end with a non-pivotal rotating axle 8, the ends of said axle being equipped with suitable wheels 6-6 and 8-8. Keyed to the rotating rear axle 8 intermediate the ends thereof is a cord or cable drum 9. Rigidly attached to the frame 5 preferably adjacent the forward end thereof is the base plat-e 10 of a perpendieularly extending hollow standard 11 having cross openings at predetermined points throughout its length. Arranged upon the upper end of this standard 11 is a collar 12 spaced from the standard 11 by a suitable bearing structure 13 to facilitate the easy turning movement of the collar upon said standard. The upper end of this collar is formed with a vertically extending yoke 14, while extending through the collar and into the standard 11 isa shaft 15, said collar, said standard and said shaft being formed `at predetermined points with openings so that the Serial N'o. 280,766.

shaft may be secured at a desired position within the collar and within the yoke, the lower end oi the shaft resting upon a cross pin extended through the standard at a prei determined point.

The invention further consists of a beam member 16, preferably of channel bar formation, the same being formed adjacent one end and at its side walls with spaced openings so that the beam may be pivoted between the legs oi' the Ayoke 14 at a predetermined point. The rear end of this beam 16 is constructed to provide a pocket for the reception of a removable weight 18 assisting in overbalancing the outer end of the beam.

Between the inner end of this `beam 16 and@ the standard 11 is a set of three retrac tile coil spring units 19. As disclosed in Figure 4 each unit consists of a pair of coil springs, the inner ends of all of the units being connected to a cross link plate 20, the upper ends of the springs of the sets being connected to a clevis 21 that is pivoted at its ends to the endof the beam 16, while the outer ends ot' the lowe'r springs are connected to a plate 22 that is connected in turn to a pair of links 23-23 that are pivoted to opposite sides of the standards 11. Within this set of springs a further retractile spring 24 is connected at its end to the standard 11 and the beam 16. Obviously these springs serve to normally retain the outer end of the beam 16 in elevated position. Furthermore they serve to center the beam 16 and to cause the swinging of the same to center position should the beam be turned away from center position in the raising or lowering of an object.

Connected at its inner end to the yoke 14 Within the side walls of the channel beam 16 is a horizontal channel beam 25 braced to the collar 12 by an inclined brace arm 2G. The top Wall of the horizontal beam 25 is out out toward the outer end of the beam and arranged between the side Walls ot this horizontal beam at the cut out portion there of is a triple channeled pulley 27. Arranged between the side walls of the beam 16 adjacent the outer end thereof is a triple channeled pulley 28, while trained over the channels of these pulleys is a cord or cable 29, one end of which is attached to the drum 9, while the opposite end thereof is anchored to the beam 16 directly in back of the pulley 28. Connected at one end to the forward end of the beam 16 and at its opposite end to the forward end of the beam is a loose cord or cable slidable upon which is a lifting hook or grapple 31. Obviously the turning of the rear axle 8 of the toy will result in the winding or unwinding of the cable 29 thereon for lowering the forward end of the beam 16 against the action of the springs 19 and 24, and the raising of the forward end of the beam 16 under the action of said springs and weight 18 so that an object hooked upon the hook or grapple 31 will be lowered or raised.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a toy crane of the character described, a frame having cross axles at its opposite ends, one of said axles being rotatably mounted with respect to the frame, the opposite ends of said axles being equipped with wheels, a cable drum keyed to the rotatable axle, a standard extending perpendicularly from the frame, a beam pivv oted adjacent one end to the upper end of the standard, means between the rear end of the beam and the standard for normally drawing the rear end of the beam downwardly, a horizontal beam secured at one end to the standard, cable pulleys associated with 2. In a toy hoisting crane of the character described, a frame, a cable drum mounted for rotation with respect to the frame, a standard extending perpendicularly from the frame, a beam pivoted adjacent one end to the upper end of the standard, spring means between the rear end of the beam aud the standard for normally raising the outer end of the beam, a horizontal beam secured at its inner end to the upper end of the standard, cable pulleys associated with the outer ends of said beams and a cable trained at one end over the pulleys ot the beams and attached at its opposite end to said cable drum.

3. In a toy hoisting crane of the character described, a frame` a standard rising from the frame, a cable drum rotatably mounted on the frame, a head structure, a swinging beam pivotally carried by the head structure, a pivotal connection between the head' structure and the upper end of the standard, spring connecting means between the rear end of the beam and the standard, whereby to normally raise the outer end of the beam, a horizontal beam secured at its inner end to said head structure., cable pulleys journaled in the outer end of said swinging and horizontal beam respectively, and a cable trained at one end over said pulleys and attached at its opposite end to the cable drum.

In testimony whereof I affix my signature.

EDWARD HAASE.
