WRECKING CRANE.
Application filed Marchv 2, 1925.k Serial'Nd 12,697.
To all whom t may concern:
Be it known that we, FRED E. SHUTT and MAnoUs H. RINEHARnciti/zene of the United States, residing at Mount Liberty, in the county of Knox and State of Ohio, have ins vented new and useful Improvements in Wrecking Cranes, of which the following is a specification. This invention relates to an improved wrecking crane for motor vehicles, the gen* eral object of the invention being to provide a crane adapted to be placed on a motor vehicle and having two sets of winding means thereon for operating cables for picking up wrecked motor vehicles and the like.
Another object of the invention is to make the boom part of the device with several sets of pulley holding means so that the pulleys can be placed in the most advantageous position according to the work to be done.
A further object of the invention is to provide means whereby one set of cable operating means can be driven by worm means when desired.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing our invention in detail, reference will be had to the accompanying drawings wherein like .characters denote like or corresponding parts through out the several views, and in which Figure 1 is a side view of the improvement.
Figure 2 is a plan view thereof.
Figure 3 is a longitudinal sectional view through the upper portion of the device.
Figure 4 is a section on line 4:-4 of Figure 1. c
In these views, I indicates a supporting frame which lis adapted to be placed on a platform 2 or other part supported by the motor vehicle. This-frame carries a boom 3 which is composed of two parallel beams 4 which are bolted together by the bolts 5 and which are held in spaced relation by the sleeves 6 on the bolts. This boom extends upwardly and forwardly at an angle and carries cross bars 7 at its upper portion, each bar having its ends extending beyond the the beams withV the extended portions hooked, as shown at 8. These hooked portions are adapted p to support pulleys, such as shownV at 9.' An upper drum 10 is mounted on a shaft 11 at the top of the frame and saidk shaft 11 is connected by the gears 12 with a shaft 13 journaledin the top ofthe frame and having one end squared, 'as at 1'1'-,
to receive a crank handle, such as shown at 15, so that thek drum can be 'rotatedby hand so as to wind thereon a cable 16 which is passed through-a pulley 9 and which may have a hook 17 fastened to its free end. A Ylower drum 18 is fastened toashaft 19 which is ournaled in the frame adjacent the vertical center thereof and this shaft 19 is connected by the gears 20 with a shaft 21 which n has one end provided with a squared part 22 to receive the crank handle and which also has a worm gear 23 thereonfor meshing with a worm 24 on a shaft 25 which is slidably and '7 rotatably supported by the bearings 26 ar ranged on one side of the frame. This shaft.v also has a squared end for receiving the crank handle 15. By moving the shaft 25 longitudinally the worm 24: can be moved out of engagement with the worm gear Q3 so that the shaft 21 can be rotated by the crank handle but when a heavy load is to be llifted the shaft 25 is moved to place the worm 24E in mesh with the worm gear 23 so that the 8 leg Ycan be lifted through the worm gear.
From the foregoing it will be seen that we have provided a large winch and a small winch, the small' winch being operated through a crank handle while the large one is operated through either the crank handle or the worm gearing. being lifted should need steadying a. cable can be placed on the top winch and fastened to the wrecked car to keep it in an upright position while the large winch yis. used in moving the car. The cable on the top winch can also be used as a guy wire by fastening it to a tree, pole or the like and in this case the wire will be high enough up as not to It is thought from the foregoing descrip- If the wrecked car tion that the advantages and novel features Y of our inyention will be readily `upparent.
lVe desire'it' to be iiiideretdod that We .may make changes in the construction and il). the combination and arrangement of Lhe seizeral parte,` provided that Such changes vfall Within the scope of the appended cla-inns'.
What We claim is l l. A crane of the dass described coinprising` an upright fra-ine, a stationary boom Supported by .the frame, a light Winch on the top of the. frame., a heavy Winch supported ab the lower part of fthe. frame, a crank handle for turning either ivincli and a number of pulley Su'pporti'ng-means on the `boom.
2. A crane of the class described comprising` a supporting frame, a stationary boom spported thereby, a light winch at lthe fop of the frame, a heavy-'Winch at thelower part 'of the frame, a Crank handle'for operating' either Winch, a Slidahle shaft journaled inthe frame, a Worm thereon, Worin gear 011 one of the shafts of the heavy Winch with which the, worin is adapted to nicsh when Iifs shaft is moved in'one direction, niegan@ for permitting the Worin shaft to be operated by the crank handle, and pulley supporting means on the boom.
3. A crane of the class described comprising a supporting frame, a hoorn supported fhereby, a iiiiiiibeifof transverse Shafts on the boom having their ends projecting be'- yond the booni, hooksA formed on the said projecting ends for receiving piilleys and awinch supported by the frame.
In testimony Whereoi We aiiix our signatures.
