3 Claims.

be termed a load article, such as a vehicle.

Thus, when applied to an automobile, the front or rear end maybe elevated, or any wheel elevated, or the entire automobile elevated. It is to be understood the automobile is solely representative of a load.

A feature of the invention resides in the use of two independent frames and three hoists, or selectively associating one or more thereof with one or two frames. I

The hoist may be hand operable as illustrated in Patent No. 2,287,551, dated June 23, 1942, or Patent No. 2,377,324., dated June 5, 1945. In certain instances where a single hoist is to carry a double load the arrangement shown in Fig, 1 of Patent No. 2,351,665, dated June 20, 1944, may be used. Ihe last patent also mentions other suitable hand operable hoist patents.

Accordingly the hoist interior mechanismis neither illustrated or described except to state that the hoist is handle operable, and raises the load step by step, lowers the load similarly, and free chain operation can be utilized with no load thereon.

One or more hoists selectively associated with one or more frames is the gist of the'present invention.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying. drawings and the following description and claims:

In the drawings Fig. 1 is a diagrammatic plan view of an embodiment of the invention as applied to both ends of an automobile.

. Fig. 2 is a front elevation of a frame-anda single, centrallydisposed hoist.

Fig 3 is an end elevation of the same.

Fig. 4 is a top plan view of a modified form ,of base, the associated tube being shown in section.

In Fig. 1 of the drawings 10 indicates an automobile having front and rear bumpers H -and I2 frame connected as at I3 and I4; Disposed fore and aft of same is a frame [5 and [6. (Each includes an upper transverse portion ll provided with two end sockets l8 and a central socket l9.)

When the entire vehicle is to be elevated the two frames l5 and. 16 are disposed in confronting relation and in immediate proximity to the bumpers of the vehicle.

By way of illustration, the front end is centrally associated with a hoist hook of a hoist structure as previously indicated and which structure is detachably mounted in central socket I9. The rear end is associated by connectors M with hooks of a pair of hoist structures detachably mounted in end sockets I8.

Thus a three point suspension is provided for bodily elevation of the load. As stated the centrally disposed hoist may be reevingly connected to the vehicle so that the double load is within the safe limits of the single chain, see Fig, 1, Patent No. 2,351,665.

If but one end of the load is to be elevated, as for spring and axle repair and replacement, but one frame is utilized and either a central mounted hoist or a pair of end mounted hoists are utilized.

If one wheel is to be elevated, but one frame and one hoist is utilized. Whenever the vehicle is to be canted to one side or the other, a pair of frames with a pair of hoists end mounted thereon are used or a single frame is longitudinally disposed alongside the vehicle and one, two, or three hoists mounted thereon and secured to the vehicle as desired or required. 3

As stated, the foregoing load applications are given by way of illustration only and the load is described and illustrated as an automobile for example purposes only, for the load may comprise a wagon which is to be tilted for dumping by way of a second example.

a Reference will now be had to Figs. 2 and 3 wherein the self-sustaining frame is illustrated in detail. The frame comprises a pair of elongated parallel tubes 2| each of which is nested in a socket 22 in an elongated foot providing a base 23 and secured therein as by bolting or pinning 24'.

In Figure 4, in longitudinal alignment with the base and projecting therefrom there is shown a fork or horn 25 mounting axle 26 carrying wheel 21, the periphery of which may be 'said to be tangential to the lower plane of base or foo-i723.

Projecting upwardly, see Fig. 2, from each tube 2i is a smaller tube 28 (part l8, see Fig. 1). These may be suitably secured together. An angle 29, see Fig. 2 (part H, see Fig. 1), has one web as shortened at each end to accommodate tube 2|. The other web 3! is apertured at 32 to rest upon the immediately adjacent end of tube 2| and permit tube 28 to extend upwardly therethrough. All the aforesaid may be suitably secured together if desired.

The cross member 29 includes a central upwardly directed socket member 33, see Fig. 2

.is secured axle I25 and mounting wheel I27.

3 (part 19 in Fig. 1). These sockets 28 and 33 are arranged for selective reception of a depending stem 34 rigid with hoist housing 35 having swivel hook 36, handle 37 and chain 38, the latter terminating in chain hook 39.

A U-shaped bar 49 with the ends ll is disposed parallel to overhead cross bar 29. Each end 4| lies against the confronting side of the adjacent tube 2|. A bolt or rivet 42 extends through said tube and through end' li anda nut or head 43 rigidizes the connection.

A pair of straps are directed upwardly and inwardly from the aforesaid connections. Herein each strap 44 has an end 45 anchored adjacent end 4! to the tube 2| and by the same means. The upper end 46 may be similarly anchored to the cross member 29 through openings .41 therein and by bolt and nut means 48. Thus the frame is V-braced and cross braced to prevent cross-member sagging, leg spreading or frame weaving.

Whenever desired or required cross-member 29 may be detachably connected to tubes 2| and the cross-bracing, if utilized, may also be de tachably mounted, as well as feet 23. Thus for shipment, the frame can be shipped knock-down and readily assembled.

The-assembled frame can be grasped at the cross-bar, if used, and tilted bodily clockwise upon wheels 27, see Fig. 3, and rolled to the desired location and then reversely tilted until the bases 23 bear flatwise on the supporting surface. When this occurs the frame is self-sustaining in upright relation.

Then one or more hoists are applied, the hooks and chain preferably being disposed on the side adjacent web 30 and then load connected. Handle operation initially removes slack in the chain and then elevates the load. Tilting of the frame under load into the load is prevented by the elongated portions of the bases or feet 23.

Thus a single hoist and one frame can be utilized to elevate either. of two adjacent corners of a load or centrally disposed to elevate the adjacent end of the load.

To facilitate frame movement transversely same may have one base 23 as shown in Figs. 2 and 3 and another base E23 as shown in Fig. 4. The latter base includes two transversely disposed wheel yokes or horns I25 in each of which If desired both bases of the frame may be ofthis type. When the frame is to be moved between .cars, etc., the side wheels are utilized for frame positioning immediately tothe side of the car after the end wheels have been utilized for frame positioning between cars, etc.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended claims.

' The invention claimed is:

of spaced parallel members, an elongated foot at the lower end of each member and disposed transverse to the plane of said members, a crossmember connecting the parallel members at the other ends thereof, a cross-bracing between the members and spaced from both the feet of the said cross-member, hoist seating vertically directed socket formations disposed at the ends of the cross-member and medially between the same, each socket formation being adapted to selectively receive and support a hoist, one of said feetat one end including awheel, the axis of which is spaced from and parallel to the crossmember and to the plane of said first-mentioned members and another wheel, the axis of which is disposed in transverse relation to the first wheel axisv of the said foot.
