Specification of Letters Patent. Application led April 17, 1911. Serial No. 490,641.

Patented sept. 19,1911.

To all 'wlwm it may concern:

lBeit known that I, LESLIE S. HacKNEY, a citizen of the United States, residing at St.

' Paul, in the county of Ramsey and State of have invented a new and useful Minnesota, f h h o w 1c VAutomobile Hoist and Turn-Table, the following is a specification.

An object'of the invention is to provide means whereby auto-ears and other vehicles may be readily and easily handled for inspection, for repair, and for other purposes, and whereby the work of repairing is. made easier and less expensive than heretofore, and the repair-pits now common may be dispensed with.

-The invention may be embodied in various forms and materials, and includes the apparatus, combinations and parts more fully s et forth in the subjoined etailed description.

One purpose of this invention is to make the inspection of the mechanism of an automobile so convenient and easy that such inspection may be frequently made by' the owner or chauffeur, for the purpose of discovering and tightening' loose bolts, for cleaning and oiling the machinery, and for the discovery and, replacement or repair of any weak or broken parts, thus to avoid danger from accidents;

The invention consists-in a hoist having "an open base on which the machine to be inspected or repaired maybe raised so that the inspector or repairer can easily get at the bottom of the machine, and hoisting devices are arranged to separately raise and lower the four corners independently, thus to allow the machine to be tilted in any direction desired, andto be brought into any position required.

The accompanying drawings illustrate the invention in the form `at present deemed most desirable.

y Figure l is a broken view partly' in section, showing the hoistand turn-table with an auto-ear thereon. Dotted lines indicate a position to which the car may be brought to bring themeehanism, not shown, of the car into position for convenient access by the repairer. The posts or towers and one side of the base are broken to contract the view. Fig. 2 is a view of the hoist with the car turned halfway over tov bring its axles into upright position. The base is broken to contract the view. Fig. 3 is a broken side elevation of the hoist with a car thereon. Fig. 4 is a broken elevation of the apyparatus with a car elevated thereby. Fig. 5"

is an enlarged fragmental detail to il trate the means fory shiftingthe car sidewse preparatory to tilting the car.' The view is shown in section on line indicated by w,

Fig. 3. Dotted linesl indicate the tilting position. Fig. 6 is a fragmental elevation from the right of Fig. 5, showing the hoisting-hook and portions of the chain and upright track. Fig. 7 is a View of the parts that go to make up the `adjustable joint shown in Fig. 3, for connecting the upper ends of the towers or posts at each side of the hoist. Fig. 8 is a section of said joint on line :118, Figs. 8, 7 and 9. Fig. 9 is a plan of the apparatus broken to contract the view and sectioned to show various features of construction; the hoisting gearing being shown as wlienapplied at only two of the posts. Fig. 10 is an enlarged fragmental view to illustrate more clearly one of the carriage-bars. Fig. 11- is a sectional detail of a carriage-bar on.line w, Fig. l0. Fig. 12 is a fragmental section on line indicated at m12, Figs. 9 and 10.

The apparatus is provided with casters l that rest on a smooth floor 2. Said casters may be of any suitable character, and an desired number of wheels may be employe In the drawings a pair of casters is shown supporting each of two sills 3 at the opposite ends of the apparatus. Upon each of the sills 3 are mounted two posts or towers 4 which may be of any construction that will serve the purpose; there being four towers in all. y

The sills are connected together by extensible joists 5 that hold the sills invfixed and rigid relation to each other. Each of said joists may consist of members 6` and 7 other by adjustable side-stays which may consist' of rods A14, 15, 16, 17, held by a clamp l18 formed of three plates 19, 2O and 21; the

outer lplates

19, 20, being provided on their innerfaces with two

grooves

22, 2 3, and the inner plate'being ungrooved on both faces. The l,three plates are held together by a bolt 24 that extends through one grooved :plateand the middle plate, and is screwed into the other grooved plate.

'The depthof each groove is less than the diameter of a stay-rod, and the rods lare seated' therein and gripped between the plates when .the bolt 24 is screwed home. By loosening the bolts and 24 the sills 3 1- and the posts thereon may be adjusted tol Ward and from each other, thus to increase and decrease the length 'of the hoist so as to accommodate cars of different lengths.

Each sill is provided on the top with a channel-rail made of angle-irons to support and guide the rollers 26 that are mounted on the ends of the carriage bars 27, 28 which support thefront and rear axles of any vehicle that is to be handled. Said lcarriagebars 27 and 28 are of like construction, and each is provided on its upper face with two wheel-

seats

29, 30 by which the Wheels 3l and the

axles

32,33 of the machine maybe supported when the Wheels are in their. seats. Said wheel-seats 3() may be provided with grooves 34 to keep the wheels from sliding from the seats. The wheel-

seats

29, 30 of `each carriage-bar are fixed to a top-plate 35, and eachtop-plate'is slidable endwise on and adjustably'tlxed to its carriage-bar by means of the headed studs 36 extending through slots 37 in the carriage-bar, and is also fastened by a clamp-bolt 38 that is xed to the carriage-bar body and extends through a slot 39`in the plate 35, so that by loosening the nut. of the bolt 38 the plate may bey lslid toward one or the other end of the carriage-bar,y thus to shift the vehicle toward one or the other side of the hoist as may be desired.

At the end of each carriage-bar there is provided means in the form of clevises 40 into which attaching means as hooks 41 may "be hooked for the purpose of lifting the ends of the carriage-bars from the sills and also relatively to each other. That is to say, the ends may be raised equally or unequally to keep'the vehicle level or to tilt it.

The hooks 41 are carried by sprocketchains'42 respectively, said chains being provided with cross-bars 43 and the hooks being Ahook-shape at both ends; one of said ends 44 being adapted to engage any of the bars 43 of the chains so that thehooks maybe connected to the chains at any portion thereof. v The chains 42 shown are endless sprocketchains carried by pulleys 45 at the tops of l the p osts4 and driven by sprocket-wheels 46 at the bottom of said posts. The driving A extra holes 61 sprocket-wheels 46 are controlled by suitreverse rotation by any suitable means as al' brake or ratchet. In the drawings, for this purpose a pawl.49 engages a ratchet-wheel 50. Eachpost, its chains, sprocket-wheels and the gearing to drivethe lower sprocketwheel, constitutes a hoisting -mechanisln ordevice capable of raising and loweringthe end of the carriage-bar to which its chaln may be connected. i When all of the hooks 41 are caught in the clevises 40 and are also caught upon the cross-bars 43 of the sprocket-chains, the n hoisting devices may be made to lift all ends of the carriage-bars 27 and 28equally and thereby bodily lift any vehicle that may vbe on said bars, thus carrying the vehicle up to any'desired height and enabling the attendant to go beneaththe vehicle to give attention to the mechanism thereof.

ln order to hold the vehicle firmly on the carriage-bars and also to support the same on saidbars with the wheels 31 free `from the wheel-seats 29, jacks composed of swivelheaded screws 51 screwed into bases 52 that may in some instances be fastened by bolts 53 to the sliding-plate 35, arer provided with clips 54 by which the jacks -may be` fixed to the

axles

32 and 33. There are four such jacks, two beingprovided for each axle-tree. The bases and tops of said jacks maybe provided with ears 55, 56, and into these ears are hooked'stay-

rods

57, 58 that are adjustably connected with each other by adjustable joints 59 corresponding to those previously described as being composed of

plates

19, 20 and 21, and bolt 24, andspeciically shown in Figs. 7 and 8. By loosening the bolts 60 of said joints 59, the rods may be slid'through the joints, thus allowing the jacks to .be adjusted toward and from each other when the bolts 53 for securing said jacks to the plate 35 have been unscrewed to allow the grooved plates to turn relatively;

it being understood that where such adjustment of the jacks on the plate isrequired for the bolts 53- may be provided. v

Adjustable stays of the character just described are applied not only between the jacks of each carriage, but also between the jacks of each side of the apparatus, so that.

when the apparatus is lengthened or shortened the sliding joints 59 of the longitudinal stays formed by the rods 57 58 may be adjusted as required; l

A crank and hoisting gearing may be providedfor each of the driving sprocketwheels at each'of the posts, or one for the driving sprocket-wheels at one of the posts on each side. In Fig. 9 of the drawings the hoist-mechanisms of one side are connected by a shaft 62 and the hoist-mechanisms of Vthe other side are connected by a shaft 63;

and

couplings

62 and 63 respectively ane provided for said rods adjacent the posts so that the mechanisms may be disconnected in case it is desired to operate the hoisting devices independently of each other.

When it is desired to tilt the automobile the hoisting-hooks'on one side of the appa- `ratus will be unhooked from their clevises the hooks 41 on that side of the machine upWard,--said hooks being hooked over the bars on the inner limbs of the ends otthe sproeket-ehains,-another attendant may hold back on the crank 48 on the other side of the apparatus, thus easing the lower end of the carriage-bar toward the posts up which the carriage-bars are bein-g drawn.

In this Way the automobile may be brought into position with the axles upright as shown in Fig. 2. d

In the form shown in Fig. 2 Ithe jacks are not provided with the ears and the brace-rods shown in Fig. 1, but brace-rods 67 are applied between the top plate 35 of 4the carriage-bar and the axle 32 of the automobile, and said axleis ydrawn toward the carriage-bar by turnbuckles 68 that are jointed to the carriage and to the bracerods 69, which brace-rods have slotted feet 70 through which bolts 71 having spannernuts72 thereon are passed, so that said feet may be slipped along the top plate in case adjustment therealong is required.

`When it is desired to lower the car to horizontal position from the position shown Vin Fig. 2, the appropriate housing-mechanism will be operated to draw the exible connection 64 toward the posts toward which the lowerends of the carriage-bars inust be moved in order to lower the Vehicle to horizontal position. At the same time another attendant will hold back on the hoistingmechanism at the side from which the vehicle is being lowered, and in this manner the vehicle will be again brought to horizontal position. Then if it is desired to elevate the vehicle, the iexible connections 64 will be unhooked from the carriage-bars,

and the clevises thus released will be agaiir connected by the hoisting-hooks 41 with the inner limbs of the sprocket-chains. Thereupon, by simultaneously operating the hoisting-devices the machine may .be lifted bodily Thenv as the attendant turnsthey .and horizontally to any position, and may also be tilted by operatinV the hoisting-devices so as to raise and lower the various ends-of the carriage-bars relatively to each other; thus to allow one end of one ybar to descend while another end of the bars is ascending.

-In case itis found after the automobile is fixedto the top or sliding plate 35 that it,

is desirable `to shiftthe automobile toward one or the other of theposts, the flexible connectionsy 64 may be hooked into the eyes 73 at the ends of the sliding plates 35, aiid the cranks may be operated upon that side,

thus to cause the flexible connections to pull the sliding plates toward that side of the hoist.

The gearing 47 may be of any requisite character, and in the views is shown as consisting of a pinion 74 meshing with a spur-wheel 75 to which a pinion 76 is fixed,

:Stub-shaft when it is desired tooperate the driving sprocket-heel at that post froin the crank at another post operating through the

shaft

62 or 63.

The apparatus may be installed in a garage or machine-shop, or in any other place where the vehicle to be raised and lowered, or to be tilted for inspection or repair, or for dumping loads therefrom, or for any other purpose-is to be handled; and may be, trundled about the floor on the easters 1 which are swiveled so that the' apparatus may be turned to any position that may be desired in order to get the best 'light on the work. The y'open base frame coniposed of the sills and joists will interfere but slightly with the movements ot' the person who desires to inspect or to operate on the mechanism at the uiider-side of the inachine, and the operator may stand on the rfloor and do the work upon the parts ot' the 'understood that while I have shown sprocket wheels and chains, hooks for connecting the inner sides of thechains with the object to be raised and lowered, and fiexible connections adapted to pass under the lowersprocket wheels and to be detachably connected with such object. to move the same toward or ease the Isame from the sprocket i wheel'under which the connection is passed,

that any known substitutes for sprocket chains and other devices thus shown may be employed withoutdeparting from the spirit of this invention.

It is understood that thechains may be operated to lift the wheels clear from their seats when this is required for the purpose of taking oii" the wheels, and that the vehicle thus upheld by the jacks alone may be handled as before described.

Vertical tracks

80, 81 are provided onthe inner side of each ost for the rollers 26 so that when the carriage-bars are drawn into tilting position said rollers will allow the ends of the bars to move up freely. Said tracks are formed of angle-irons to constitute guides to prevent: the rollers from moving laterally off the track.

Pro s 82 may be inserted under the carriage ars, and such bars lowered to rest vthereon when an automobile is elevated as shown in Fig. 4, thus to morel or less take oif the strainy from the chains and to insure great safety.

The bars 2T and 28 and the connections between the same and the vehicle form an open frame to support the vehicle and allow free access to "the underside ofit, and

other forms of frame`=than that show n'may be employed for the same purpose without avoiding the invention.

l claim: l. Four seats for vehicle wheels` rigid means to connect the seats together in pairs, rollers at the ends of said rigid means, upright and horizontal tracks upon which said rollers are .adapted to roll and means to raise and lower an end of said rigid connecting means while the rollers are in contact with the tracks.

2. A hoist. comprising a movable balse,bars on said base, rollers at and extending operably beyond the ends of the bars, upright and horizontal tracks for said rollers, hoisting 'devices for detachable yconnection with the bars. and means detachably connecting the hoisting devices with the ends of the` bars respectively, for the purpose of drawing the bars alone the tracks with the rollers in engagement with said tracks. c

3. A hoist comprising a bar, a plate adapt-l` ed to slide on said bar, means on said plate Ato support one end of a vehicle, vertical endless chains adjacent the ends of said bar,

means to operate the chains, and means to alternatively connect the lends of said bars with the opposite sides of said chains.

A. The combination of two posts, sprocket wheels at the tops -o-f said osts, sprocket' wheels at the bottoms of said) posts, endless chains around the sprocket wheels of the respective posts, a v-bar between the posts, means to operate the lower s rocket. wheels respectively, means for detac ably connecting an end of the bar with the inner side of the chain adjacent thereto, and a, flexible connection adapted to extend under the lower sprocket wheel and to detachably connect an end of the bar with the outer side of the chain adjacent thereto.

5. A hoist comprising four endless chains, tour iosts, sprocketwlieels on said posts to support the chains, sprocket-wheels underneath the first-mentioned sprocket-wheels to drive the chains, gearing to operate the chains respectively, a bar between two of said posts, meansfor detachably connecting the ends of one bar with the inner sides of the chains adjacent thereto, a flexible connection adapted to extend under a lower sprocket-wheel and to alternatively connect the ends of said bar with the outer sides of said chains, means to detachably connect the ends of the other bar with the inner sides of the other two chains and to connect the ends lof said bar alternatively with the outer sides 7. A hoist comprising two bars, means to connect said bars to a vehicle, vertical endless chains ad]acent the ends of said bars, means to operate the chains, and means to alternatively connect the ends of said bars with the opposite sides of said chains.
