UNITED STATES JOHN ROBERT ROBERTSON, OF NEW GLASGOW, NOVA SCOTIA. CANADA.
1.1311116 .01: ron AUTOMOBILES.
j bpplicaflon filed November 7, 1922. Serial No. 599,554.
To all whom it may comm-.1,
Be it known that I j JoHWRoann'r Ronmrn son, a subject of the of Great Britain, and a iesident of NewGlas ow, in the Province of Nova Scotia and ominion of Canada, have invented certain new and useful Improvements in Liftin Jacks for Automo iles, of which the i0 lowing is a specification.
This invention relates to improvements in lifting jacks for automobiles, and the objects of the invention are to provide a lifting jack which will have, incombination with a nniveral point, an exceptionally 16 long lift.
Further ob ects are to provide a. lifting jack with an internal screw nonrotatable an an external rotatablescrew operated by a worm gear, in'turn through universal joint means operated by a speed wrench.
With these and other olg'lects in view, the invention consists essenti' ly in. the novel arrangement and construction of parts hereinafter described in the specification and illnstrated by the accompanying drawings that formpart of the same. Referring to the drawings, in which like characters of reference indicate correspondin% parts in each figure, and in'which:
Figure 2 is a vertical section.
Figure 3 is a section on the line 3-3, 'of Figure 2. Figure 4 is a plan view of a speed wrench for opemting'the jack and also for turning nuts.
In the drawings; v
A is the lifting jack comprising a main or principal casting 10, provided with a suitable ca 12, screw secured in place and adapts to sheter a gear hereinafter more fully referred to. Within the castin 10 is an outc'r left-hand screw 14, provid with two key seats, full lengths, while 15 is an inner right-hand screw provided with a central rod 16 having a suitable key, and adapted to fit a pin 11. 17is an 00 ably engaging with the casting 10 and riveted to t 0 rod 16.
18 is a worm provided with an operating spindle or shaft 19 and designed to mes with a gear 20 keyed to the outer screw 14 at 21. '22 is the apertured end of the spindle 19 designed to form one member of a universal joint of which 23 and 241m: the
above construction and on nut'slid- 'l other members connecting the spindle 19 with a tubular member .55 formed with'n sleeve 26 on the end, fitted to a hexagon rod 2? designed to telescope with the tubular member 25. 28 is a hexagon fixedly secured on the rod 27 by means of a pin 29 to prevent the rod 27 from turning. The exagon 28 is adapted to engage with the socket end 30 of a wrench B shown in Figure 4. 13 is a rest pivot on the inner screw 15 adapted to engage with and support the axle of a car or velncle.
From the foregoing, the operation of my invention can be readily understood, and
is as follows: Place the jack under the car,
pull out the extension handle to the length iequired, the universal joint permitting one to stand at almost any angle. Then place the wrench on the end 29 and operate. As
the wrench is turned, the worm 18 operates the gear 20, which turns the screw 14, and, as the screw 15 is held from turning by the rod 16 and nut 17, an upward motion of both screws is secure It will therefore be seen that I have invented a jack of simple and economic construction which, in combination with the universal joint and a telescopic handle, can be operated at any required le without the necessity of stopping or ot erwise inconvcnicncing the operator.
It will also be noted that in my jack, the outside is the driver or rotating screw, and that the inner screw is fixed, as far as retatable motion is concerned, being held by a. rod or actagon nut, and the movement of this screw thus confined to an up and down one.
As many changes could be made in the many apparently widely difierent embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all mattor contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense,
What I claim as my invention is:
1. A lifting jack for automobiles, and the like, comprising an inwardly threaded casing, a screw adapted to engage with said casing and threaded on the inside to engage with an oppositely threaded inner screw, 8. concentrically arran ed rod adapted to slidably cage with e inner screw and fixedly seen to the casing, whereby the rotation of the inner screw is prevented, means carried by the inner screw adapted to support the ax e of a. vehicle, and means for operatingthe outer screw to raise and lower the inner screw, and comprising the 5 line gear keyed to said outer screw and esigned to slidably en go with the outer screw, 1 wormgear mes rug with the spline gear, and a spindle for theavorm gear, connected through a. universal joint at its outer end with telesoopic handle means to operate the lifting jack from a. distance. r
2. A lifting jack of the character described, comprising a suitably threaded casing, a, pair of oppositely threaded screw members arranged one within the other and adapted to engage with said casing, a. rod for said members adapted to'slidobly engage with the inner screw, means for operating the screw members to raise or lower the inner screw,,a,xle supporting means carried by the inner screw, and 0 rating means comprising s line gear on shaft means adapted throng universe-i joints means and a. telescopic handle to be operated from a distance.
In witness whereof I have hereunto gt my hand in the resenoe of two witnesses JOHN R BERT ROBERTSON.
