DICKENS, F HAGERSTOWN, MARYLAND, ASSIIGNOR '.EC)v DICKENS AUTO TRANSMIESSION I-IOIST COMPANY INC., OF HAGERSTOWN, MARYLAND HOIST Application ined september 1e, 1931. serial No. 563,212.

rlhis invention relates to a hoist and has forits primary object to provide, in a mannerl as hereinafter set forth, a device of this` character which is portable Vand which embodies a novel construction, and arrange ment of'parts, whereby same is adapted particularly for use in removing and replacing transmission units of automobiles in an expeditious manner.

a Other objects of the invention are to provide a transmission hoist which will be simple inconstruction, strong, durable, eihcient and reliable in use and whichmay be manufactured at lowcost.

5 All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the followingspeciication, taken in connection with the accompanying drawings, wherein like char- G acters ofreference designate corresponding parts throughout the several views, and

wherein Figure- 1 is a view in vertical section through a hoist constructed in accordance with the present invention.

Fig. 2 is a View in vertical cross section taken substantially on the line 2--2 of Fig. 1, looking in the direction indicated by the arrows. j 0 Fig. 3 is a view in horizontal cross section taken substantially on the line 3 8 of Fig. l, looking downwardly as indicated by the arrows.

F ig. 1 is a View in top plan showing the hoistin position for use.

Fig.v 5 is a vertical sectional view taken substantially on the line 5&5 of Fig. 1.

Fig. k6 -is a vertical sectional view taken substantially on the line 6-6 of Fig. 1.

Fig. 7 is a detail view in perspective of one of the transmission supporting bars.

Referring now to the drawings in detail, it ,will be -seen that the hoist constituting the present invention comprises atubular bar 1 which extends slidably thru the horizontally disposed feet 2 and which has its ends provided with the caps 3. These feet 2 are equipped with the supporting casters 4. The reference numeral 5 designates rods which are d isposedinl spaced parallelism with the tubumembers 10 which telescope into the lower members 9.

rThe members 9 and 10 are provided with series of openings 11 which are adapted to be brought into registry for the reception of the pins 12 for securing the upper members 10 in adjusted position. The pins 12 may be secured to the lower members 9 of the standards 8, through the medium of a chain 13, and a ring 14.

One of the upper members 10 of the standards 8, is provided at its upper end, with a bearing 15 in which one end portion of a horizontally disposed tubular shaft 16 is journalled.. The other upper member 10 has rigidly mounted thereon an upstanding casing 17 which is secured 1n position in anyV suitable manner, as by a pin 18. A shaft 19 is journalled horizontally in the casing 17 and has an enlarged end portion 20 projecting therefrom for engagement in the other end portion of the tubular shaft 16 for supporting same.

Suitable means, such as a pin 21, is employed .for connecting the tubular shaft 16 to the enlarged projecting end portion 20 of the shaft'19 for rotation with said shaft 19. The inner end of the enlarged portion 20 of the shaft 19 is provided with a collar 22 against which the adjacent end of the tubular shaft 16 abuts. Y Y

A worm gear 23 is fixed on the shaft 19 in the casing 17. Journalled in the casing 17 above the shaft 19 and at right angles thereto, and projecting from the said casing 17 is a shaft 24 having fixed thereon a worm gear 25. A hand crank 26 is mounted on the projecting end portion ofthe shaft 24 for manually rotating said shaft. If desired, the hand crank 26 may be removable. A hoisting chain 27 has one end fixed to the tubular shaft 16 and is windable thereon.

If desirable or necessary, more than one hoisting chain 27 may be provided. The end of the tubular shaft 16 which is supported in the bearing is provided with a cap 28.

Mountedjfor slidingradj ustment on the rods 5 are the anti-clinal transmission supporting bars 29, the apex portions of which rest on the tubular bar 1. At their ends the bars 29 terminate in the upstanding eyes 30 which slidably encircle the rods 5. The bars 29 are slidably adjustable toward and away yfrom each other to accommodate different sides of transmission units. In Fig. 4 of the drawings, a transmission unit is designated by the j reference numeral 31, the same being shown in broken lines. A portion of the frame of a vehicle is also shown in broken lines in Fig. 4 ofthe drawings and designated by the reference numeral 32. o

In use, the floor boards of the vehicle which are forward of the drivers seat are removed. The feet 2, with the standards 8 and tubular shaft 16 removed therefrom are then rolled under the vehicle into position beneath the j transmission. The standards S are then mounted in the socket members 7 and the members 10 of said standards are adjusted vertically as desired. Then, the tubular shaft 16 is mounted in position and extends transversely above the transmission. The

I hoisting chain 27 is then secured properly to the transmission after which said transmission may be unbolted and lowered to the supporting bars 29. The worm gears 23 and 25 prevent rotation of the tubular shaft 16 except when actuated by the hand crank 26. TWith the transmission'resting on the bars 29, the tubular shaft 16 and standards 8` are again removed in order that the lower portions of the hoist with the transmission thereon may be rolled from beneath the vehicle. j

It is believed thatthe method of replacing the transmission will be apparent from the foregoing description.

It is believed that the many advantages of a hoist constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described,

j j it is to be understood that changes in the details of construction and in the combination and arrangement of parts, may be made which will fall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is u 1. A hoist comprising a bar, a pair of feet slidable on the bar for adjustment toward and awayy from each other, supporting casters on the feet, standards rising from the feet, a
