COMBINATION? LIFTING DEVICE AND TABLE.

Application filed December 14, 1923. Serial No. 680,754.

This invention contemplates the provision of:a combined crane and work support or table, primarily designed for use in automobile repair shops, to facilitate the removal of a motor from the machine and the subsequent"work'to be done thereon. '1 More specifically stated, the invention provides a crane including'a wheeled frame so that the crane can be shifted-from one place to another as the occasion may require, the frame being further designed to pass over the machine and straddle the object to be dealt with, so that tor or either end ofthe machine need to be lifted, it can be conveniently handled, and in case of the removal of the motor irom the machine, the motor can be elevated onto a table or work support which is also carrie'd by the frame of the crane.

The nature and advantages of the invention will be betterunderstood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference -indi-- cate similar parts in the several views, and wherein: r

Fig. 1 1s a sideelevation of the device;

Fig. 2 is an end elevation of the device,

Fig. 3 is a plan view of the device;

Fig. 4 is a vertical sectionalview of the device; Y i

' Fig. 5 is a detail view of one of the working tools;

Fig. 6 is a detail view of a toolbox or the like.

Referring to the drawings in detail, A indicates generally a supporting frame of the crane, and it is to be understood that this open frame like structure can be constructed from angle iron or any other suitable material and also vary in size and configuration without departing from the spirit of the invention. The frame is mounted on wheels 10 so that it can be easily moved from place to place, the frame is open at both ends as clearly shown, the sides of the frame including spaced upper and lower members 11 which are connected together by a vertically disposed bracing element- 12, and diagonally arranged similar elements 13. The vertically disposed bracing elements of the re spective sides are connected togethervby a shoulc the mo-' transverse beam 14: which in turn is braced by the. bracing members 16. The upper members 11 of the respective sides of the frame are connected together by a plurality of transversely arranged angle irons 17 the latteibeing arranged in pairs, with said pairs disposed at either side of the vertically disposed bracing elements 12. Each pair of these angle irons constitute a support for a work table 18 so that there is one of these tables arranged at each end of the machine, thus allowing two motors to be worked on at the same time. It will be further observed that each pair of angle irons 17 are connected together by similarly constructed members 19 which are received by grooves :20 in the underside of the work tables so as to support the latter against movement with relation to the supports therefor. Asabove pointed out, the invention is primarily intended to be used byautomobile mechanics, to facilitate the removalof a motor from the machine, which is frequently necessary in order to repair the motor. It is the intention to construct the frame of the crane hi h enough and wide enough to allow it to be moved over the automobile, so that the frame will straddle the machine to position the crane proper in the most convenient relation to the motor to be lifted. crane proper is so arranged that when the motor is elevated above the machine it can be conveniently positioned upon one or the other of the work tables 18. The crane arm is mounted for rotary movement so that it can beswungto project from either end of the frame, depending of course upon which work table is to be used, or upon, whether or not one or the other ends of the machine is to be elevated instead of removing the motor; The space, between the respective pairs of angle bars 17 provides a compartment having a tool box or the like indicated at 20, this box reposing upon the upper members 11 of the frame proper. Then again, at one side of the frame I make use of the brackets 21 to which is secured a ledge 22 which is coextensive in length with the length of the frame, and this ledge is to support one or more Vises indicated at 20.

Rising from the frame just described is a super-frame like structure including opposed side members made up of angle iron bars, or the like 24, which are connected at their upper end by spaced parallel side and Then again, the lifting.

end members and 26 respectively. The parallel members 25 are also connected to a metallic plate 27 which supports a circular guide 28 about which the crane arm 29 rotates. The crane arm is supported on the upper end of a hollow tubular member 30 which passes through the guide just referred to and journalled in the latter and also in the angle bar 31 which connects the side members of the super-frame like structure. Gne end of this crane arm is provided with a groove 32 which receives the periphery of the circular guide 28, which not only guides the arm in its movements, but also assists in relieving the forward end of the arm of undue strain when in use. Supported upon the arm is a guide pulley 34 over which is trained a cable 35, the cable being also trained over a similar guide pulley 36 journalled on the forward end of the crane arm, and thence passed over the movable pulley 37, the free end of the cable being associated with a hook 38 received by an eye 39 depending from the crane This cable passes downwardly through the hollow tubular member or shaft and supports the crane arm, and is adapted to be wound about and unwound from a pulley 39 fixed on a transverse shaft 40, the latter being journalled in suitable bearings tl supported by the opposed side members of the super-frame like structure. This shaft 40 is provided with a gear 42 which meshes with a smaller gear 43 which is carried by a stub shaft 4A, the latter being also mounted in suitable bearings for rotation. Fixed on the same shaft a l is a larger gear 4L5 which meshes with a smaller gear 46 fixed upon another stub shaft 4:7. This latter mentioned shaft is equipped with a crank handle 48, so that by turning the handle, rotary motion is imparted to the shaft 40 through the chain of gears to wind or unwind the cable depending of course upon the particular direction of rotation of the shaft 40. Depending from the movable pulley above referred to is a plurality of lifting chains 49 which support clamps 50 of suitable construction, so that the motor or other object to be lifted can be secured to the chains as will be readily understood. Arranged immediately beneath the crane arm and supported by the transverse angle iron which connect the sides of supporting frame, is a pair of tool boxes 51, there being one for each work table. Arranged at the top o f each tool box is a transversely disposed ledge 52 from which depends a plurality of hooks 53 on which the tools or other parts can be suspended within convenient reach of the workman. Then again, carried by the rear end of the crane arm is an eye 54 to which a cable or the like can be secured at one end, and its other end attached to some fixed object to prevent the crane from moving forwardly while an object is being lifted.-

Mounted on one side of thesuper-frame like structure is an emery wheel 55 carried by one end of a shaft '56, the latter being journalled in bearings associated with-a pair of spaced parallel plates 57. These plates are connected at their ends .and supported in brackets 58. Fixed upon the shaft 56 and arranged between the plates 57 is a gear 59 which meshes with a larger gear 60 carried by the shaft 61 also journalled in said plates 57, the shaft 61 being equipped with a crank handle 62 so that the emery wheel can be conveniently rotated to sharpen tools or for an other use as the occasion may require. A uitable ball and ratchet mechanism 62 is also used to support the object lifted at any degree of elevation.

While it is belived that from the foregoing description, the nature and advantages of the invention will be readily apparent, I

desire to have it understood that I. do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described claim: I, I p Y r A device of the character described comprising a wheeled frame open at both ends to allow the frame to be moved over an ob ject to be lifted, a super-frame like structure rising from the first mentioned frame and including a disk constituting a guide, a crane arm mounted on said super-structure for rotation and having a groove formed in one end thereof to receive said guide, a shaft arranged transversely on said super structure and mounted for rotation, a hollow tubular member positioned above said shaft and passed centrally through said arm, a cable adapted to be wound about and unwound from said shaftand passed upwardly through said tubular member, and means for rotating said shaft.

In testimony whereof the invention, I

EDWARD w. ens-Ks.
