TOY DERRICK Harold B. Boone, Arcadia, Kans. Application September 8, 1950, Serial No. 183,873 7 3 Claims. (01. 212- 55) This invention relates to toys, and more particularly to a miniature derrick or bucket hoist.

A main object of the invention is to :provide a novel and improved toy derrick or bucket hoist, which is very simple in construction, which is easy to operate, and which is very useful in teaching children proper coordination of hands and feet.

A further object of the invention is to provide an improved toy derrick or bucket hoist which is relatively inexpensive to manufacture, which is sturdy in construction, which is readily movable from one location to another, and which provides useful exercise as well as entertainment for children.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a side elevational view of an improved toy derrick constructed in accordance with the present invention;

Figure 2 is a rear end elevational view of the toy derrick of Figure 1;

Figure 3 is a top plan view of the toy derrick of Figures 1 and 2;

Figure 4-11 is a side elevational detail view of the brake member illustrated in Figure 4;

Figure 5 is an enlarged top plan detail view, partly in cross-section, of the inner section-of the extensible boom employed on the toy derrick of Figure 1;

Figure 6 is a detail plan view of the outer section of the extensible boom employed in the to derrick of Figure 1; g

Figure 7 is a diagrammatic view illustrating the cable connections employed for extending and retracting the telescopic boom of the toy derrick of Figure 1;

Figure 8 is a longitudinal, vertical, cross-sectional view taken through the telescopic boom of the toy derrick of Figure 1.

Referring to the drawings, ll generally desig to the forward ends of the longitudinal members l5, I5 is a transverse, horizontal platemember l1, and rigidly connected to the forward comers of the plate member I! are depending bar. meme bers l8. Extending rotatably through the lower portions of the bar members I8 is a transverse axle I9 carrying the respective supporting wheels 20, 20. As shown in Figure 1, the frame portion II is normally supported on the legs [2, I 3 and I4, but may be transported by elevating the rear portion of the frame I I whereby the forward portion will be supported on the wheels 20. This enables the frame to be readily moved from place to place.

Designated at 2! is a vertical post member or upstanding post which extends rotatably through plate member I? and is supported on the forward end portion of the plat member 16 for rotary movement about a vertical axis or a bearing 22. A boom 24 is arranged longitudinally of the frame II and forwardly of the post 2| and embodies a first section 25 having one end connected to the post 2| intermediate its ends for up-and-down movement about a horizontal axis or pivot 23, and a second section 26 having one end receiving the other end of the section 25 and connected to the section 25 for extensile and contractile movement. The section 26 is provided adjacent its other end with an eye 21 to which is secured one end of a cable 28. Cable 28 passes over a pulley 29 rotatably mounted in the upper portion of, the vertical post member 2|, the end of said cable being connected to an eye 30 secured to the top portion of the post member. Designated at 3| is a weight suspended from a pulley 32 engaged on the cable 23 adjacent the post member 2|. Designated at 33 is a latch member or locking lever pivotally mounted on a transverse pin 34 secured in the top :portion of the post member 2| said latch member having a serrated end 35 and being provided at its opposite end with a weight 36, the serrated end 35 being located inwardly adjacent the cable 28 and the Weight 36 biasingsaid serrated end into locking engagement with the cable.

As viewed in Figure l, the weight 36 biases the pivoted latch member 33 in a clockwisedirection,

whereby the end 35 is urged against the depending portion of the cable 28. Engagement of the serrated end 35 with the cable 28 restrains the boom 24 against clockwise rotation, as viewed'in Figure 1, whereby said boom may be releasablylocked in an elevated position; The locking lever 33 may be moved counterclockwise to 2. released position to release cable 28 by means of a release rod 3? extending upwardly through the post member 2| and engaging thelower surface ofth'e lever 33 subadjacent theweight portion 36. The

E3 mounted on the pivot pin 23.

lower end of rod 3'! is pivotally connected to one arm of a bent lever 38 pivoted to the frame H, the end of the other arm of said lever being connected by a rod 39 to the arm M] of a crankshaft 4| rotatably mounted on an upstanding bracket 42 carried by the frame H. The lower ends of the bar members i2 and 13 are connected by a transverse bar member 43 to which the bracket 42 is secured. A, similarv transverse, bar member 44 connects the lower ends of the support elements N.

The crankshaft 41 is provided with a foot actuable means or handle 45 which is adapted to be operated by foot pressure. When the crankshaft M is rotated counterclockwise, as viewed in Figure l, the rod 39 rotates the bent lever 38 clockwise, causing the release rod 31 to be moved upwardly, whereby the lever 33 is rotated counterclockwise, allowing the cable 28 to be'released.

Designated at 46 is an upstanding bucket which-is arranged adjacent-the other end of the second section 26 and-has the upper end dependingly supported from the other end of the section 26. Specifically, the bucket 66 is detachably connected to'a pulley' ll supported on a cable 48. One end of the cable is connected to the other end of the section 26 of the boom 24, the cable passing over a pulley 48a rotatably mounted in the end of the section 26, said cable 38 extending over a pulley 49 rotatably mounted in the top end of the post member 2|, and thence beneath a pulley 50 carried on the upper portion of the frame H to a reel 5! journaled transversely between the rear support bars l2 and i3; Reel 5| is provided with a hand actuable means or crank handle shown at 52. The bottom end of the bucket 45 is connected by a short length of cable 53 to the outer section 2% of the boom 24', and is further connected by a cable 54 which passes over a pulley 55 carried by the section 26 of the boom and over another pulley 56 carried on a rearwardly extending arm 51 secured to the inner end of the section 26. A weight 58 is slidably mounted on the cable 54 between the pulley 55 and 'thebottom end or the bucket.

As shown in Figure 8, a transverse pin 59 extends through the inner end portion ofthe section 26 and passes through respective longitudinal slots 60, 60. formed in the inner boom section 25. A pulley (ii is provided in the outer end pore tion of the section 25. Designated at 82 is a cable connected at one end to thetransverse pin 59 andwhich extends over the pulley 6i and thence back-through the section 25over a pulley Another cable 64 is connected to the transverse pin 59 and also extends over the pulley 63. The cables 64 and 62 extend downwardly through the lower portion of the post member 21 and around pulleys 65, 66 carried by the frame H. The ends of the cables 64 and 62 are wound on a transverse shaft 8! journaled in the vertical support members [2 and I3. Shaft 61 is-provided with'a crank nandle 68 and has rigidly secured thereon a ratchet wheel 59. Engaging the ratchet wheel 69 is a dog lilrwhich is biased in any suitable manner into locking engagement with the ratchet wheel to lock the boom sections in extended relation until the dog member is withdrawn from engagement with the ratchet wheel. Designated at H is a foot actuable means or crank adapted to be foot operated and which is rotatably supported'on a bracket 12 secured to the transverse bar member 43. Member H is connected to the .dog ill by a link 13, whereby foot pressure on the member H causes the dog 10 to be withdrawn from engagement with respect to the ratchet wheel 69. It will be readily apparent that by rotating the shaft 6'! by means of the crank 68, the boom may be extended, and that the boom may be collapsed by disengaging the dog member 10 from the ratchet wheel 69, whereby the outer section 26 of the boom will telescope over theinner section 25 by gravity, assuming that the boom is in an elevated position. If the boom is in a depressed position, it may be collapsed by merely reversing the rotation of the crank 68, at the same time holding the dog 10 disengaged from the ratchet wheel 69 by means of the foot-operated member H.

' Mounted on the lower portion of the post member. 21 isa pulley 13a around which extends a cable 14. Cable "M is wound on a transverse shaft 15 journaled in the upper portions of the vertical bar members 12 and i3, said shaft being provided with a hand aotuable means or crank handle. F6; Rotation of the crank handle 16' in one direction causes the post member 2! to swivel in one direction, and rotation of the crank handle 16 in the opposite direction similarly reverses the direction of swiveling'of the post member 2!.

A typical method'of operation of the above-described toy device is as follows:

The operator places both feet on the' pedals H and 45, places his right hand on the crank 52 and his left hand on the crank '68. It will be understood that the boom 24 is in its'lowered, collapsed position at this time. The operator then rotates crank 63 which causes the boom to be extended and at the same time causes the bucket 46 to 'dig into sand or loose dirt subadiacent to the boom. After the bucket has been filled, the operator rotates the crank 52 to elevate the boom, at the same time releasing both of the foot operat'ed members 11 and 45. Dog T0 will engage the ratchet wheel 69, holding the boom in extended position. The boom is elevated to the desired height by means of the hand crank 52, the locking lever 53 engaging the cable 28 and supporting the boom at its desired elevation. While raising the boom with his right hand, the operator may swing the boom either to the right or.left by rotating the crank 16 with his left hand. The boom may be swung substantially a complete revolution. To discharge the load, the operator merely releases the crank 52, allowing the cable 48 to unwind from the reel 5!, whereby the cable 53 causes the bucket 46 to be inverted as it descends. The operator may then raise the bucket by rotating-the crank 52, at the same time using the crank 16 to bring the boom back to the loading position. The operator may then engage his left foot with the crank H, allowing the .boom to return to its collapsed position by gravity, and the boom may then be lowered to its starting position by exerting foot pressure on the crank 45, which releases the cable 28. Thedevice is then ready to repeat the abovedescribed operation.

While a specific embodiment of an-improved toy hoist device has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
