2 Claims.

This invention appertains to new and useful lmprovements in toys and more particularly to a toy steam shovel.

The principal object of the present invention is to provide a toy in the nature of a steam shovel or like digging apparatus which can be manipulated in a manner simulating the control of an actual steam shovel.

Another important object of the invention is to provide a construction of the character, described which will be durable, positive acting and not susceptible to the ready development of defects,

These and various other important objects and advantages of the invention will become apparent to the reader of the specification.

In the drawings:

Figure l represents a side elevational View of the apparatus. A

Figure 2 represents a top plan view.

Figure 3 is a fragmentary horizontal sectional view.

Figure 4 is a fragmentary vertical sectional view through the rear portion of the apparatus.

Figure 5 is a fragmentary vertical sectional View Il through the entire apparatus.

Figure 6 is a rear elevational view of the scoop.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the base, preferably constructed of sheet metal from the side portions of which vertically extend the risers 6-6 for supporting the horizontal shaft 1 on which are rockable the levers 8, 9 and I0.

Extending rearwardly from the base 5 are the arms II-II which are `bridged by the shaft l2 on which are the pulleys I3, I4 and I5 over which are trained the cables or cords I6, I1 and I8, respectively. These cables are trained and guided through wire guides I9 carried by the shaft I2.

Numeral denotes the derrick truck having the wheels 2I on the axles 22 and these axles 22 are anchored in place on the platform 5 by suitable means 23.

Numeral 24 represents the body structure of the u derrick from which depends the tube 25 and this tube extends through an opening in the truck 20. The lower end of the tube 25 is flanged outwardly as at 26 for aording a swivelled connection of the tube 25 with respect to the truck 20. l0 Leg members 21 extend downwardly from the truck 20 and support the rollers 28-29 over which the cables I1-I8 extend.

These cables I1--I8 extend over the pulleys I4I5 and connect to the lower end of the levers u 9--IIL One end of the cable I1 connects to the 1938, Serial No. 196,759

upper portion of the shovel shank 36 and extends downwardly under the pulley 32 and then backwardly to pass over the double pulley 3l and downwardly through the opening and tube 25 and rearwardly to have the lever 9 connected 5 thereto and then over the pulley I4 to extend forwardly and upwardly through the tube 25 and to pass through opening 30 and over double pulley 3| and over the roller 32 and extend downwardly to connect to the lower portion of the shovel 10 shank 36 by the anchor Ila.

The cable I8 extends over the pulley 38 on the floor of the body 24 and extends upwardly over the large pulley 39 at the upper end of the beam 40 and downwardly to connect to the bail 4I 16 which attaches as at 42 to the shovel 31 at the forward portion thereof.

The cable I6 extends horizontally under the body 24 and around the large pulley 43. This cable I6 is endless and by actuating the lever 8 Si? the pulley 43 can be rotated so as to swing the entire body 24.

By actuating the lever 9, the shank 36 of the shovel 31 can be lifted or lowered with respect to the beam 40 and by actuating the cable I8, the 2&5 shovel 31 can be lifted or lowered with the pin 33 acting as the fulcrum.

Obviously by simultaneously manipulating the lever 8, which constitutes a body or cab rotating lever, and the lever 9, which constitutes the shank 3G elevating and lowering lever, said cab 24 may be rotated and the shank 36 raised, or lowered simultaneously. Also by simultaneously manipulating said lever 8 and the lever Ill, which constitutes the shank swinging lever, the body or cab 24 may 35 be rotated and the shank 36 swung simultaneously. Also by simultaneously manipulating the levers 9 and IIJ the shank 36 may be simultaneously raised, or lowered, and swung as desired.

The shovel 31 is of the open back type adapted 40 to be closed at its rear by a flap-like gate 41 provided at its top edge and adjacent opposite sides thereof with a pair of upwardly bowed hinge leaves 44 by means of which and pins 44' said gate is pivoted to the sides of said shovel for 45 movement under .the influence of gravity to opened and closed positions in diiferent angular positions of the shovel shank 36 and the shovel 31.

The gate 41 is adapted to be releasably latched in closed position by means of a latching frame 43 50 slidably mounted in guides 43 on the rear side and lower end of the shovel shank 36 for gravitational movement in one direction to latching position and for operation in the opposite direction into 4unlatching position. Under movement of said frame 43 in a latching direction, a curved resilient finger 45 thereon rides over the lower edge of a slot 46 in the upper edge of the gate 41 and thereby cams said gate closed. A pull line operatively connected to said cables adjacent to said pulleys, the cable connection to said shank extending from its related pulley beneath said cab and having a portion extended upwardly through 42 is provided for operating the latching frame/the latter, and the mounting for said cab being in an unlatching direction, said line being connected to said frame, as at 44a, and anchored to the top of the body structure 24, as at 42h.

Obviously, if the frame 43 is moved to unlatching position, and the shovel shank 36 swung out of vertical, the gate 41 will swing open to permit the shovel 31 to dump the contents thereof. As will be understood the frame 43 may be moved manually to latching position at any time if desired.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to -without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In a toy power shovel, an elongated base, a

-cab rotatably mounted on one end of said base,

a boom extending upwardly from said cab, a shovel shank pivotally and slidably mounted on said boom for swinging and endwise operation thereon, and remote control means for simultane- -ously rotating said cab and operating said shank comprising a plurality of pulleys rotatably mounted on said base adjacent the opposite end of the latter, cable connections between said pulleys and said cab and shank, respectively, and hand levers constructed and arranged for rotation of said cab about said portion, whereby fouling of said cable connection by said cab under rotation thereof is obviated.

2. In a toy shovel, an elongated base, a cab, means to mount said cab at one end of the base for rotation thereon comprising a truck, a hollow sleeve depending from the iioor of the cab and journaled at its lower end in said truck, the ends of the sleeve being open, a boom extending upwardlvfrom the oor of the cab out of the same, a shovel shank endwise movable in opposite directions on said boom, remote control means for rotatingV said cab, and remote control means for moving said shank comprising an idler pulley rotatably mounted at the other end of said base, a pair of lower and upper pulleys mounted on said truck and the top of said cab, respectively, a cable trained around said idler pulley and. under and over said lower and upper pulleys, respectively, said cable extending through said sleeve and having its ends operatively connected to said shank to move the same in ,opposite directions under operation 'of said cable in opposite directions, and a lever pivotally mounted at said other end of the base and operatively connected to said cable to move the same.
