AUTOMOBILE HOIST.

Application filed January 2, 1926. Serial No. 79,050.

This invention relates to automobile hoists and the like and more particularly to a structure of this character employing as a hoisting means arotatable jack shaft and an operating motor therefor.

An important object of the invention is to provide a mounting for the operating motor such that the weight thereof is centralized to the structure and the structure may accordingly be properly balanced.

A further object of the invention is to provide a device of this character including a rotatable jack shaft, a motor axially aligned with the jack shaft and planetary gearing interposed between and connecting the jack shaft and motor.

A still further object of the invention is to provide a device of this character in which'the housing of the planetary gearing provides a support for a housing sleeve for the jack shaft protecting the jack shaft from the entry of dust and dirt.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown'a preferred embodiment of my invention and wherein Figure 1 is a plan view of hoisting aparatus constructed-in accordance with my invention;

Fi view therethrough; p

Figure3 is a plan view partially in section showing one of the units.

Referring now more particularl to the drawings, the numeral 10general y designates a. vehicle receiving platform including bracing beams. 11.- These bracing beams combine to support, a hollow casting 12 formed centrally with a bore 13 receiving a motor housin 14. At the lower end of the bore, a shou der 15 is produced limiting ddwnward movement of the motor housing into the bore.

the bore is provided, this cap having an endbearing 17 for the armature shaft 18 of the motor.

Secured to the under surface of the casing 12 is a cupped housing 19, the upper ends 0 the side. walls of which are provided with ears 20 through which securing elements attaching the same to the casing 12 and indicated at 21 are directed. In the bottom of this housing, a bearing 22 is formed co-axial with the motor shaft 18 and this bearlng reeeives the reduced upper end 23 of a threadstub shaft 38 to which gure 2 is an enlarged vertical sectional train. The disk 37 is 'A cap or closure 16 for the spec ed jack shaft 24'. Between the body of the ack shaft and the lower face of the cupshaped housing, a thrust bearing 25 is introduced. Surrounding the shaft 24 is a supporting tube 26 in the upper end of which is mounted a nut 27 through shaft 24 is threaded. The mounting for the nut includes an outwardly extendin flange 28 which bears against the inner sur ace of a housing sleeve 29., the upper end of which is fitted and secured to the outer walls of the cup-shaped housing 19. This sleeve is splined to a ring 30 which is supported from the housing 31.0f the jack shaft. It will be seen that as the structure above described elevates, the sleeve 29 will elevate therewith and through the ring 30 will maintain with the housing 31 a complete enclosure for the jack shaft, preventing the entry of dust and dirt thereto.

The upper end of the reduced portion 23 of the jack shaft projects into the cup-shaped housing at the lower end thereof and has keyed thereto, as at 32, a disk 33. having secured thereto an orbit gear 34 mounted in the disk on pivots 35 upon ed at the upper surface of the diskplanet gears 36 meshing with the orbit gear 34. A

provided with an axial is secured a gear 39 forming the sun gear of this section of the likewise provided with an orbit gear 40 and planet gears 41. The sun gear 42 of this train is secured to the armature shaft 18 of the motor. This gear similar disk 37 .is

and the end of the armature shaft rest upon a thrust bearing 43 seated in an axial depression; formed in the upper sur disk 37.

It will obvious that by the. structure recited, an even distribution of we ght is afforded and that the jack shaft 1s driven which the jack which are mountface of the from the motor at-a much reduced rate of d through the compound planetary train provided by the disks'33 and 37 and their associated elements. Itv will also be obvious that the construction hereinbefore set forth 7 ca able of a certain range of mo ification without materially from the spirit of the invention limit myself to isobviousl change an departing and I accordingly do not such specific structure except claimed.

I claim 2-- as hereinafter o 1. In a combined elevator and turntable for vehicles, a vehiclesupportmg structure, a.-

casting supported therefrom and havinga centrally located motor housing, a motor arranged Within the housing with its shaft vertically directed, planetary gearing operated from and arranged co-axially with said motor shaft, a housing for said gearing, a

threaded jack shaft supporting the housing 'vertically directed, planetary gearing operated from and arranged co-axially with said motor shaft, a housing for said gearing, a

threaded jack shaft supporting the housing and an extension on said jack shaft projecting into the housing and operatively connected with said planetary gearing, said jack shaft being co-axial with said motor shaft.

3. In a combined elevator and turntable for vehicles, a vehicle supporting structure,

a casting supported therefrom and having a centrally located mote-r housing, apmotor arranged Within the housing with its shaft vertically directed, planetary gearing operated from and arranged co-axially with said motor shaft, a housing for said gearing, a threaded jack shaft supporting the housing, an extension on said jack shaft projecting into the housing and operatively connected with said planetary gearing and a housing sleeve supported from the housing of the planetary gearing and surrounding said motor shaft.

4.'In a combined elevator and turntable for vehicles, a vehicle supporting structure,

a casting supported therefrom and having. a

centrally located motor housing, a motor arranged within the housing with its shaft vertically directed, planetary gearing operated from and arranged co-axially with said motor shaft, a housing for said gearing, a

- threaded jack shaft supporting the housing,

an extension on said jack shaft projecting into the housing and operatively connected with said planetary gearing, the planetary gearing including a pair of disks eachhaving an orbit gear and planet gears associated therewith, one of said disks being secured to said jackshaft, the other of the disks having a sun gear for the first named disk and a sun gear for the last named disk secured to, said motor shaft.

5. In' a combined elevator and turntable for vehicles, a vehicle supporting structure, a casting supported therefrom and having a centrally located motor housing, a motor arranged within the housing with its shaft vertically directed, planetary gearing o erated from and arranged co-axially with sai motor shaft, a housing for said gearing, a threaded jack shaft supporting the housing, an extension on said jack shaft projecting into the housing and operatively connected with said planetary gearing, the planetary gearing ineluding a pair of disks each having an orbit gear, planet gears associated therewith, one of said disks being secured to said jack shaft, the other of the disks having a sun gear'for the first named disk and a-sun gear for the last named disk secured to said motor shaft and a thrust bearing interposed betwen the sun gear of the motor shaft and the last named disk.
