CHARLES T. NELSON, OF OAKLAND, NEBRASKA.
AUTOMOBILE-JACK.
Specification of Letters Patent.
Patented May 1, 1917.
Application filed October 4, 1916. Serial No. 123,749.
To all whom it may concern.
Be it known that I, CHARLES T. NELSON, a citizen of the United States, residing at Oakland, in the county of Burt and State of Nebraska, have invented certain new and useful Improvements in Automobile-Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in automobile jacks.
The object of this invention is to provide a jack which is particularly adapted for use in connection with motor vehicles and the like, and is designed to provide a device whereby the vehicle may be readily run over the same and lift it from the ground so that the tires clear the ground thereby relieving them of any unnecessary strain and preventing them from coming in contact with the surface of the ground when not in use.
Another object of this invention is to provide a device which will simultaneously lift the machine or the vehicle and hold the same against accidental movement.
A still further object of this invention is to provide a novel form of lifting means and also to provide a pair of supporting bars which may be readily inserted under a machine so that the same may be quickly and readily-raised with a minimum expenditure of energy.
WVith these and other objects in view the invention consists in the novel combination and arrangement ofparts hereinafter more fully described and pointed out in the claims hereto appended.
In the drawing Figure l is a perspective view of my improved jack including the Windlass for raising the same.
Fig. 2 is a detail sectional view.
Like numerals of reference designate corresponding parts in all the figures of the drawing.
Referring more particularly to the drawing, the numeral 1 designates one of the base members of the device while the numeral 2 designates the cooperating base member. The base members are preferably formed of wood or any other suitable material and so constructed as to lie even and firm upon the ground and to provide a frame of suitable construction for supporting the jack structure which will be hereinafter more fully described.
The members 1 and 2 are arranged at a relatively spaced distance apart and have rotatably mounted near each of their ends shafts 3 and 4:, which are designed to support the supporting arms 5. The shafts are held to the base members 1 and 2 by suitable staples 6 which permit the free rotation of the shafts which rotation will be hereinafter more fully set forth.
Secured to the shafts 3 and 4: near their ends and within the space between the base members 1 and 2 are the lifting arms 5, each of which comprises at their lower end a sleeve member 7 which is rotatably mounted on the shafts 3 and 4. The mounting of the sleeves around the shafts acts as a support for the arms 5. The upper ends of the arms 5 are bifurcated to provide supporting arms 8.
Pivotally mounted in the arms 8 are the longitudinally extendin supporting bars 9 which bars have each 0% their ends fitted in the slot defined by the arms 8 to rest upon the bottom wall of the slot formed by the bifurcating of the arms 5. The arms 8 of each of the members 5 are provided with alining transversely arranged openings 10 through which is adapted to extend the reinforcing bars 11.
The reinforcing bars 11 are substantially V-shaped and have their apeXes slidably mounted through the eyes 12 of bolts 13 which are removably secured to the shafts 3 and 4- intermediate the ends thereof. The opposite ends of the members 11 are bent angularly in a horizontal direction and are removably extended through openings 10 in the arms 8 and the bars 9 permitting the bars to move downwardly and upwardly upon the movement of the arms 5.
A bail member 13 has each of its ends rigidly secured to the forward lifting eletherein near each end, through which the bars 14 extend. Pivotally mounted between the bars 14 at a point intermediate the ground and their upper ends is a suitable bail 16, the use of which will be more fully hereinafter described. Rotatable between the bars near their upper ends is a shaft 17 carrying thereon the winding drum 18. This shaft is provided at one end with a gear wheel 19 and at its opposite end with a suitable ratchet wheel 20, which is designed to cooperate with a pawl 21 to hold the shaft and drum against rotation in one direction. A suitable flexible member 22 is connected at one end to the drum 1S, and passes over one of the pulleys of the double block 23,
which has a hook 24 which engages the' bight portion of the bail 13.
The opposite end of the flexible member is passed through the block 25 and extended again through the block 23 and has its end connected to a hook 26 carried by the block 25. A suitable hook 27 is also carried by the block 25 and is designed for engagement with the bight portion of the bail 16, so that a connection is established between the bails 16 and 13.
In operation it will be apparent that the car or vehicle which is to be lifted is run up over the platform or bars 9 so that the bars will engage the forward and rear axles.
The wheel 19 is then set in operation to wind the flexible member 22 011 the drum 18, this action causing the blocks 23 and 25 to be drawn toward each other, thereby exerting pull on the bails 13 and 16, causing the lifting elements 5 to move to a vertical position.
It is apparent that when the lifting elements are in a vertical position the vehicle axles will rest thereon and the wheel will be held clear of the ground, thus relieving the tires of the weight of the vehicle and also permitting any repairs to be made to the wheels which might be necessary.
What is claimed is 1. A jack of the class described including a base, a pair of shafts rotatably mounted on the upper side of the base near each end thereof, lifting elements secured by one end to the shafts at each end thereof for rotation therewith, the upper ends of said lifting elements being bifurcated forming spaced arms provided with horizontally alined openings, a pair of V-shaped reinforcing rods having their apexes removably secured to the medial portion of each shaft, the ends of the reinforcing rods being bent angularly and extended transversely through the horizontal alined openings in the arms of the lifting elements, longitudinally extended supporting bars arranged between the arms of the lifting elements and removably and pivotally secured therein by the angularly bent ends of the V-shaped reinforcing rod, and a power applying mechanism associated with certain of said lifting elements for raising and lowering the lifting elements and bars simultaneously.
th ends of the reinforcing rods, for movement with the lifting elements.
In testimony whereof I affix my signature in presence of two wltnesses.
CHARLES T. NELSON.
