1 Claim. (Cl. 254-4391) My invention relates to improvements in transmission hoists for removing transmissions from automobiles and the like.
H he invention is designed with the primary obieet in view of providing a simple form of hoist for lifting such transmissions through the floor of automobiles and removing the same out of the front door, and which is especially adapted for easy operation by one man, is safe, inexpensive to manufacture, and will not readily get out of order.
.To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claims appended hereto.
In said drawing:
Figure 1 is a View in side elevation of my improved hoist, in the preferred embodiment thereof, with parts broken away andshown in section,
Figure 2 is a view in plan, partly in section,
Figure 3 is a view in vertical transverse section taken on the line 3-3 of Figure 1 and drawn to an enlarged scale,
Figure 4 is a view in horizontal section taken on a line 44 of Figure 1 and also drawn to an enlarged scale.
Reference being had to the drawing by numerals, my improved hoist, in the illustrated embodiment thereof, comprises a V-shaped base I including a pair of side bars 2 converging toan apex web 3 provided with an upstanding socket sleeve 4. Caster wheels 5 beneath the ends of the side bars 2, and beneath the apex web 3 support said base I.
A cylindrical post 6 arises from the socket sleeve 4 with the lower end thereof seated in and rotatable in said sleeve.
A cross head I is provided on the post 6 for vertical sliding adjustment thereon and having the form of an offset T-fitting comprising a vertical sleeve 8 slidably fitted on said post, and a horizontal cross sleeve 9 offset laterally to one side of the sleeve 8 and provided with a rear end counterbore ID for a purpose presently clear.
A U-clamp II is fitted on the post 6 beneath the sleeve 8 for vertical sliding adjustment on said post to support the cross head I in different vertically adjusted positions.
A hand crank [2 extended through the clamp II and threaded into one side thereof, as at I3, provides for tightenin the U-clamp II, at will.
A tubular crane arm I4 extends horizontally from the cross head 1 with a rear end portion suitably fitted and fixed in the front end of the sleeve 9. The bore I5 of the crane arm I4 is of the same diameter as the 'counterbore Ill of said sleeve '9. e A reel operating shaft I6 is rotatably extended through the .cranearm I 4 and the sleeve 9 with a working'nt in the bore and the counterbore m and with its front end extending out of the front end of the crane arm I4 and its rear end extending out of the rear end of said sleeve 9.
A small diameter flanged reel I1 is suitably fixed on the front of the reel operating shaft I6 and retained on said shaft by a nut I8, said reel having suitably fixed thereto for winding thereon a cable I9 provided with a terminal hook 20.
A ratchet wheel 2| and a hand crank 22 are suitably fixed on the rear end of the reel operating shaft I6 and secured thereon by a nut 23, the ratchet wheel 2| being confined against lateral displacement on said shaft l6 between the rear end of the sleeve 9 and said hand crank 22.
A ratchet dog 24 is pivoted, as at 25 on the sleeve 8 to override the ratchet wheel 2 I, the pivot 25 having the form of a bolt adapted to be turned against the post 6 to lock the cross head I to said post against rotation independently of the post.
In using the described invention, the cross head I is first adjusted vertically on the post 6 to a height such that the crane arm l4 may be extended through the front door of an automobile, not shown, from which a transmission is to be removed. In so adjusting the cross head 1, the pivot 25 is first suitably loosened so that said cross head may be lifted on the post 6 to the desired position, after which the clamp I I may be adjusted on said post 6, in a manner which will be clear, to hold the cross head 'I in adjusted position. The base I is then wheeled beneath the body of the automobile to extend the crane arm I4 through the front door until the reel I1 is in appropriate position for lifting the transmission. With the crane arm I4 thus extended, said arm may be swung laterally to align the reel I I vertically with the transmission, the post 6 rotating in the socket sleeve 4 during such swinging of said arm, it being understood that after adjustment of the cross head I, the pivot 25 is to be tightened to lock said cross head to the post 6. The ratchet dog 24 may then be lifted to disengage the ratchet wheel 2| so that the cable I9 may be lowered to engage the hook 20 with a suitable part of the transmission to be lifted. With the ratchet dog 24 dropped into engagement with the ratchet wheel 2|, the hand crank 22 may then be operated to cause, in a inanner which will be clear, the reel I! to wind up the cable l9 and lift the transmission upwardly through the floor of the automobile and into a position such that by backing the hoist away from the automobile, said transmission may be removed out of said door. Obviously, the ratchet dog 24 and ratchet wheel 2| will hold the reel l7 against reverse rotation to maintain the cable l9 wound duringthis removing operation. The transmission may be replaced by substantially reversing the operations described in the foregoing, as will be understood.
The foregoing will, it is believed, sufiice to impart a clear understanding of my invention, without further explanation.
Manifestly, the invention, as described, is susceptible of modification Without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.
What I claim is:
In a hoist of the class described, a wheel supported elongated base, a post at one end of said base having a lower end rotatably mounted on the same, a cross head vertically slidable on said post into different set positions, a clamp on said post vertically adjustable thereon to support said cross head in the different set positions thereof, a crane arm extending horizontally from said cross head, to overlie said base and having a rear end fixed in the cross head, a shaft rotatable in said cross head and crane arm with a front end extending out of said arm and a rear end extending out of said cross head, a cable windin reel fast on the front end of said shaft, an operating crank for said shaft fast on said rear end thereof, and dogging means for said shaft, including a pivoted dog the pivot of which is adjustable to lock the cross head to the post.
