'A'UTOMOBILE-LIFTING DEVICE.

Specification of Letters Patent.

Application filed August 31, 1918. Serial No. 252,248.

T 0 all whom it may concern:

Be it known that I, HENRY F. FIENUP, a citizen of the United States, residing at Vellston, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Automobile- Lifting Devices, of which the following is a specification.

This invention relates-to improvements in automobile lifting devices of that class which are especially adapted for use in garages and has for its object to provide a lifting device of simple and inexpensive construction which'can be easily and readily actuated for raising all four wheels of an automobile free of the ground or floor or lowering same thereupon by the mere raising or lowering of a single lever.

' \Vith the aboveand other objects in view, the invention consists in certain novel features of construction, arrangement and combination of parts hereinafter described and finally pointed out in the claims hereto appended. V Y

In order that those skilled in the art to which the invention appertains may know how to make and use the same, I will describe the construction illustrated, in detail, and refer by reference characters to the accompanying drawings, in which- Figure 1, is a plan view of a lifting device,

constructed in accordance with my invention.

Fig. 2, is a side elevation thereof.

Fig. 3, is a detail showing the connection between the lifting-lever and the movable frame section of the device.

Fig. 4, is a plan view of a hinge-member.

In carrying out the aim of my present invention I employ a suitable stationary base consisting of the side members 1 and the end cross-pieces 2 and 3.

A pair of suitable supporting legs 4 are hingedly connected as at 5, in spaced relation, to the upper face of each side basemember 1, as clearly shown in Figs. 1 and 2.

Pivotally connected, as at 6, to each pair of supporting-legs 4c is the side members 7 of a movable lifting frame. One end of the side members 7 of the movable lifting frame are connected by means of the crosspiece 8. This cross-piece is preferably secured at each end to the lower face of each side lifting member 7. The forward end of each side lifting member 7 is provided with an upwardly projecting arm 9 adapted to act as a stop for the front axle of a vehicle tostrike against to prevent the vehicle from rolling completely over the device.

The means for actuatmg the movable liftframe consists of a suitably shaped lifting or voperating-lever 1O hinged near its lower end, as at 11, to cross-piece 2 of the lower or stationary frame or base section.

tioned behind the strap member 13, of the lever 10, as clearly shown in Figs. 2 and 3. The object of having the strap 13 recessed or channeled as at 1 1, is to permit the recessed portion 14 to gradually engage the shoulder 19 of the plate 15 to render lifting of the lever 10 more easy when a load is resting upon thelifting frame due to a slipping movement caused by the recess 14% coming into gradual contact with the shoulder 19 of plate 15.

It will be observed that when the lifting frame is in its lowermost position, as shown in Fig. 2, that the cross-piece 8 thereof 'is resting upon the lower end of the lifting lever 10. When it is desired to raise or lift the lifting or movable frame from the position' in dotted lines to full lines, as shown in Fig. 2, the operator merely pulls up upon the lever 10 causing it to force the lifting.

frame into its uppermost position and thereby raising the automobile tires from the dotted line position upon the ground designated A to the dotted line position designated 13 above the ground level thereby relieving the rubber-tires of all weight of the vehicle, as is manifest. To lower the vehicle so that the tires may again rest upon the ground the operator merely pulls down upon the lever 10 causing same, through the connections 13, 15, 17, and 18, to pull the lifting frame into the position shown in dotted lines in Fig. 2.

In constructing a device of the class described for raising or lifting heavy cars, I provide means adapted to assist in raising the frame at the point of greatest load upon the lifting lever 10. This means consists of Patented June 7, 1921. I

a rotatable plate 20 suitably supported upon the cross-piece 21. Fixed to the center of the rotatable plate 20 is an outwardly extending arm 22. The outer end of this arm 22 has a suitable rod connection 23 with the cross-piece 8 of the lifting frame. A'suitable arm 24: is suitably connected at one end to the rotatable plate and at its opposite end to one end of a suitable coiled spring 25, the opposite end of which is connected to the cross-piece 26. il hen the lifting frame is in its uppermost or raised position, as shown in full lines in Figs. 1 and 2, the

means just described assumes the positionshown in full lines in Figs. 1 and 2 with the spring contracted, and when the lifting frame is in its lowermost position, said means, assumes the position shown in dotted lines in Fig. 1, with the spring extended and set to assist in raising the lifting frame whenever the connecting-rod 23 forces the arm 24; out of locked position, which locked position is indicated in dotted lines in 1. Itwill be observed that this operation takes place whenever the lifting lever 10 has been raised to an angle of about l5 degrees. tl ith the pulling power of the spring 25 in addition to the force applied to the lev r 10, raising the lifting frame with a heavy automobile thercon is a comparatively easy operation.

From the foregoing description, it will be observed that l have so constructed a lifting device that can be placed in any garage,

private or public, in such a manner that an automobile may be driven over the device and by merely lifting the operating lever 10, raise the wheel of the automobile clear-of the ground or floor thereby relieving the dead weight of the car upon the tires. it takes but a few seconds to raise a vehicle, it is possible with my device to raise the vehicle each time it is placed in the garage whether for a short or long period of time. It will be readily seen that it is a most con- L LL S venient device for relievin the tires of the dead load of the vehicle over night which alone adds greatly to the life of automobile tires, as is manifest.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaption ofthe device to various conditions of use without departing from the spirit and scope of my invention and the terms of the following claims, hence wish it to be understoodthat I reserve the right to make any such changes or modifications as may fairly fall within the scope of the appended claims when fairly construed.

l i hat I claim is:

1. An automobile ack comprising a base frame, a lifting frame pivotally mounted above said base frame and connected therewith, a lifting lever having a cutaway portion hingedly connected at its lower end to d base frame, a strap iron member spanning the cutaway portion of said lever, a hinge plate fixed to one end of said movable lifting frame and extending therefrom, and a pin carried by the extended end of said hinge plate adapted to slidably engage the rear face of said strap iron member during the raising and lowering operations of the lifting lever. A

2. In combination, astationary base frame,

a movable lifting frame adapted to support a vehicle by the axles of the vehicle resting upon said movable lifting frame, hingedly connected supporting legs connecting the base frame with the movable lifting frame,

.a lifting lever hingedly connected at its lowerend to said base frame and engaging one end of the movable lifting frame when manipulated for raising or lowering said frame, a connection between said movable lifting frame and said lifting lever, one end of said connection working within a slotted opening in said lifting lever, a rotatable plate supported by the base frame, an arm extending outwardly from the center of said plate, a connection between said arm and one end of the lifting frame, a coiled spring fixed at one end to the base frame and a connection between the opposite end of said coiled spring and said rotatable plate to permit the force of thespring to assist in elevating the movable lifting frame.

In testimony whereof I have hereunto signed my name to the specification.
