ll|| llllllll'l H ili liiflrllim g-Ukunngs Sans PAT NT EMERSON B. BIRD, or SEATTLE, WASHINGTONi To'all whom it may concern I Be it known that I, EMERSON B. Brno, a

subject of the King of Great Britain, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Apparatus for Raising Automobiles; and I do hereby declare the following to be a full, clear, and

will enable others skilled in theart to which it appertains to make and use the same.

-This invention relates to lifting mechanism, and more particularly to an elevator for raising automobiles, vehicles or other organizations to facilitate the operation of a mechanic upon the underneath parts of the vehicle.

It is one of the objects ofthe present invention to providea simple, practicable, and comparativelyinexpensive elevating mechanism onto which a vehicle can, be

readily run and then elevated to a suitable height to permit a mechanic or workmanto have ready access to the lower portion beneath the bod of the vehicle.

Another ob ect of the invention is to provide means to facilitate ther'unning of the vehicle onto the elevator'a'nd to provide means for guiding the vehicle to prevent its side running, and a particular object of the invention is to provide an elevator which may be erected at any convenient location without the requirement of. alteration to the'surrounding struction and without requirement of excavating or providing a pit or the like. i

With the above and other objects in view as will be rendered manifest to those-skilled in the art, the invention consists of the-construction in combination, and in details of arrangements of the parts as more particularly hereinafter described relative to an embodiment of the invention, illustrated in the accompanying drawing, in which-- Figure 1 is a side elevation of the elevator;

Fig. 2 is a bottom plan view of the same, and v i Fig. 3 is an end view.

As illustrated, the elevator comprises a substantially rectangular frame having [strong longitudinally extending side memhers 2 of suitable proportions and dimensions which are bent upwardly at their ends 2 and formed with a horizontal portion 2 to be secured as -by rivets orother suit- Specification of Letters Patent.

able means 3 to the transverse end members 4 formed to lie in the same plane with the main body of the side members 2, and which 1 threaded nut or hearing portions 6 to take each a complementary screw 7, the lower ends of Wl'llCll rest upon ball bearings 8 mounted on the horizontal sup orts 2 and the lower ends of which screws are turned down to pass through the frame structure, and each at its lower end carries a beveled gear 9 which meshes with a set of beveled gears 10 and 11, these bein respectively secured on transverse end s afts 12 and horizontally extending side shafts 13, all of said shafts being mounted in suitable bearings 14 secured to the respective frame members and projecting beneath the overhanging supporting portions 2 and 4:, which being elevated above the bottom plane of the frame form a convenient recess for a extended as at 13 to carry and be driven by a pulley wheel or other suitable means indicated at 15.

To facilitate the running of a vehicle'on to the wheel track 5 the ends of these may be provided with extensions 5 which may be turned down to an inclined position outwardly to permit the ready running of the wheels upwardly to the plane of the tracks 5 which are disposed just above the transverse shafts 12. When not in use the track sections 5 can be folded upwardly and over the adjacent ends of the tracks 5.

To rovide for the necessary stability of the li ting screws 7,which obviously will be of such direction of pitch that when the driven shaft 13 is operated the nuts or threaded blocks 6v will be simultaneously Q merger,

and uniformly lifted by the rotation of the screws, these screws will be supported by braces 18 attached at their lower ends to the frame corners and provided at their upper ends with bearings 19 engaging reduced portions 7 at the heads of the screws.

What is claimed is: 1. An elevator for vehicles, comprising a frame having side and end sills with up- 10 turned and overhanging ends, a set of upright screws having fixed bearings in said ends, means for uniformly actuating the screws including shafts overlying said sills and journaled in the upturned part, a pair of spaced independent track members.

and individual brackets on the screws con- I necting said members to the adjacent screws whereby the former may be uniformly elevated, said frame adapted to be located fiat upon a surface over which a vehicle may be run onto the track-way, the tracks having ends deflected toward the plane of the surface, the shafts having gears all arranged above the bottom of the frame. 5 2. An elevator for vehicles, comprising a stationary frame, a set of upright screws having fixed bearings, shafts and gears for uniformly actuating the screws, a pair of spaced independent track members, and brackets connecting each of said members to respective screws at the sides of the frame whereby the members may be uniformly elevated, said frame having sills adapted to be located fiat upon a surface over which a vehicle may be run onto the track-way, the corners of the frame upset to form housing for the gear-mechanism of the driving means and through which upset part the shafts extend.

' 3. A stationary elevatorfor Wheeled ve- 40 hicles, comprising a pair of side sill mem-' bers turned vertically and thence horizontally endwise, cross or end members of similar form all rigidly connected at overlapped ends, bearings on the upright parts of the sill members and shafts supported therein and extending along and over the members, threaded shafts journaled in the corners of the frame formed by the said members,

braces mounted onthe frame and having 9 bearings engaging the upper ends of the threaded shafts, a carrier arm on each threaded shaft, relatively disconnected tracks each extending beside the adjacent side member and connected to the pair of carriers at its side of the frame and gears connecting the several shafts to simultaneously raise or lower the tracks.

- In testimony whereof I affix my signature.

EMERSON B. BIRD.
