. 2 Claims.

Broadly considered, the object ofthis invention is to provide a novel gin pole construction,

together with means for raising, lowering and operating it, the invention relating to a traversing hoist for material and article handling.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view,

which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings:

Fig. 1 shows in side elevation, a device constructed in accordance with the invention, parts being broken away;

Fig. 2 is a top plan, parts being broken away;

Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a section on the line 3-4 of Fig. 1;

Fig. 5 is an elevation showing the roller and attendant parts, portions being in section;

' Fig. 6 is a plan of one of the bracket plates;

Fig. 7 is a longitudinal section showing the mounting of the rollers and attendant parts;

Fig. 8 is a perspective view showing the guard and supporting frame;

Fig. 9 is a cross section showing the means whereby the gin poles are mounted on the truck body when not in use.

In carrying out the invention, there is provided a wheel-mounted truck body B, which may comprise lower side beams I, carrying. a lower table 2 on which are mountedcross bars 3 supporting a platform 4, the cross bars 3 being provided at their ends with carrying hooks 5, the use ofwhich will be made manifest hereinafter.

The side beams l are connected by an end beam 6, shown in Fig. '7, and to the beam 6 is secured a rearwardly extended V-shap'ed bar I.

Bracket plates 8 are secured to'the ends of the bar I. To the bar I, internally thereof, 'as shown in Fig. 7, are secured supports 9, shown also in Fig. 5. In the supports 9 is mounted an auxiliary shaft l about which is disposed an auxiliary roller supported from the shaft l0, in the present disclosure, by ball bearings 2 although, of course, any kind of bearings may be used. The auxiliary roller I projects upward- (Cl. 21H) ly through an opening I in the upper flange of the V-shaped bar I and supports the intermediate portion of' a main roller l' carried on a main shaft l6, through the instrumentality of ball bearings H, or any other equivalent bearings. The main roller I5 is disposed close to the rear end of the platform I, and is carried by the bracket plates 3.

The structure last-above described, and shown best in Fig. 7, cannot be claimed herein, per se, 10 because it is a cable guide, claimed in my copending application, Serial No. 218,232, filed July 8, 1938.

A cab I8 is located at the forward end of the truck and behind the cab is placed a guard or supporting. frame l9, shown in detail in Fig. 8. The frame l9 comprises rear legs 2| and forward legs joined at their upper ends by inclined members 22. The legs 20 and 2| are joined. 7 'f by horizontal bars 23. The legs 2| are'connect- 1, ed by horizontal bars 24 and the bars 24 are connected by posts 25, on which tubular rollers 26 are journaledfor rotation about a vertical 2 axis. The legs 2| are also connected .near their ends by ties 21. A back bar 28 connects the upper ends of the legs 2| together. The upper ends of the forward l'egs 2i are joined {by a top piece 29, the ends of which extend later- 1 ally far enough so that articles used in connec' i 35 tion with the operation of the truck may be hung upon them. With a like end in view, the rear legs 2| are supplied with books 30 or equivalent suspension elements. The lower ends of the legs 23 and 2| of the frame l3 are connected to the side beams of the truck by bracket bars 3|.

Located for the most part within the frame I9 is a winch 32, including a rotatable drum 34 about which is wound a cable 35 having a hook 36 or the equivalent at its end.

Ginpoles 33 are provided, and their lower rear ends are pivoted at 31 to the bracket plates 8 for movement either vertically or horizontally. When the gin poles 33 are not in use, the upper ends of the gin poles are separated, and the gin poles are carried at the sides of the truck body, on the hooks 5. 7

When the gin poles 33 are to be used, their upper or forward ends are brought together on top of the member 29 of the guard frame |9, and the said ends are joined together by a hanger 38 of any desired construction, the hanger carrying a sheave or block 39. The flexible element a 35 is threaded through a block 40 connected by a chain 4| or the like to the rear end of the truck body, the flexible element being threaded through the sheave or block 39 at the forward or upper ends of the gin poles 33. The flexible element is carried backwardly and downwardly over the roller i5 and the hook 38 or the like on the free end of the flexible element 35 is made fast by means of a hook 42 or other means to the rear end of the body.

If the drum 34 of the winch 32 is put into operation, the gin poles 33 will be raised to the dotted line position of Fig. 1, where they are sustained by guys 43 extended between the upper ends of the gin poles and any desired part of the truck body. The hook 36 of the flexible element is cast off the hook 42 on the rear end of the truck body and the device now is ready for use as shown in dotted line in Fig. 1.

The frame IS in Fig. 8 not only supports the gin poles 33, when they are forwardly inclined as in Fig. 1, but the frame also serves as a guard for the cab l8, and if the truck happens to roll over, the frame will protect the cab from being crushed, and the occupants from being injured.

The device is adapted to a wide variety of uses and will be acceptable to anyone having occasion to load or move heavy objects.

Having thus described the invention, what is claimed is:

1. In a traversing hoist for material and article handling, a truck, an operators cab on the truck, a frame on the truck, behind and closely adjacent to the cab, the frame extending upwardly to a greater height than the cab and laterally at least as far as the sides of the cab, to reduce the possibility of the cab being crushed 1: the truck rolls over, the cab putting an operator in the cab under duress such that he is'not exposed beyond the guarding limits of the frame, a gin pole pivotally associated with the truck and resting in an inoperative position on top of the frame, in independent relation to the cab, and hoisting mechanism operatively associated with the gin pole and mounted in part on the frame.

2. In a traversing hoist for material and article handling, a truck, an operator's cab on the truck, a frame on the truck, behind and closely adjacent to the cab, the frame extending upwardly to a greater height than the cab and laterally at least as far as the sides of the cab, to reduce the possibility of the cab being crushed if the truck rolls over, the cab putting an operator in the cab under duress such that he is not exposed beyond the guarding limits of the frame, upwardly-converging gin poles pivoted at their lower rear ends, to the rear portion of the truck, a detachable connection between the upper, forward ends of the gin poles, hoisting mechanism engaged with the connection, and supports on the sides of the truck, the gin poles resting in an inoperative position on top of the frame, in independent relation to the cab, the connection permitting the upper, forward ends of the gin poles to be separated and moved laterally and downwardly with respect to the frame, for engagement with the supports, when the gin poles are in an inoperative position.
