Application filed September 8, 1921. Serial No. 498,685.
To all whom t may conc-em:
V Be it known that I, WILLIAM B. LUCAS, a citizen of the United States of America, and a resident of Oak Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Combination Pneumatic Jacks and Tire Inaters, of which the following is a specification.
This invention relates to automobile accessories and especiall to means for raising the vehicle'aXle an tomeans Jfor inflating the tires.
The main objects of the invention are to provide a simplified form of jack adapted for automatic operation; to provide such a device of compact form and of light weight; to provide a jack of the character stated adapted for manufacture at a low cost and of few parts adapted for permanence and simplicity of operation.V
An illustrative embodiment lot' this invention is shown in the accompanying drawings, in which Figure 1 is a vertical sectional view of one embodiment of the invention adapted to serve either as a jack or a tire inlater..
Figure 2 is a vertical section' of another embodiment.
In the construction shown in Figure 1, the jack comprises a pair of relatively movable intertting members 1 and 2 disposed in mutually expansible relation. The frame part 1 is cylindrical and the chamber thereof contains a piston-like head 3 secured to the innerend of the member 2. ,The upper end'of the` member 1 is provided with a guide part 4 to retain the piston member 2 1n concentric position relative to the member 1 when the jack is used.`
The body or shaft of piston member 2 is hollow and the closed chamber thereof is adapted to contain, under high pressure, a
` fluid of normally gaseous character in liquid form.
A tube 5 is 'provided for admitting charges of. fluid successively from the storage chamber in part 2 to the expansion chamber 1n part 1. The ilow of Huid through said tube is controlled by a manually-controlled valve 6 sion chamber is controlled by a separate valve-7, preferably in the form of a spring closed needle valve which may be opened by downward'pressure with the hand as understood in the art. The valve 6 is also of the and the release of Huid from the eXpan-' needle type, so as to readily permit of very gradual opening. Y l
Whenever it 1s desiredV to use this device 'for' .inflating a tire, the lower end of tube 5 1s dlsconnected at the point 8` from the jack and connected to the nipple 9 of the tire 1'() whereupon fluid may be admitted from the supply chamber by opening the valve 6.
e, operation of the jack is as follows: The jack is placed in upright position on the ground and the head 11 is placed under the axle l2, the tube 5 being connected as shown by full lines lin Figure 1. The valve 6 is -then opened suiliciently to charge the expansion chamber in frame 1 and thereby lift the piston 2 and the load 12 carried thereby. When the load 12 is tobe lowered, the operator pres-ses his finger downwardly upon the projecting stem of valve 7.
In the construction in Figure 2 the jack 'is entirely self-contained, the chamber connecting means being inside the ljack as indicated at 13. Moreover a modified form of valve is provided at 14 to regulate the How of gas into and downward through tube 13.
The upper wall4 of the frame or base part 1 is provided with vent openings 15. to pre- -chamber is lled by connecting a supply tube at 17 in`place of tube 5.
A relatively light-weight jack, weighing for instance about five pounds, may be charged from 'time to time with a suiiicient quantity of liquid carbon dioxide to operate the jackat least fifty times or to inate a dozen tires or more. The cost of rechargin the storage chamber at the usual commercia rate for carbon dioxide is about ten cents. The many advantages of this device are apparent, particularly its simplicity and low cost, its ease ofoperation, its strength and cfluickness of operation and its low cost lboth or constructionand maintenance in use.
-vent pressure developing above the piston Although but two specific embodiments of this invention are herein shown and described, it will be understood that numerous V details of the' constructions shown may be altered-or omitted without departing -from Connection having one end communicating with said storage chamber and its other end being interchangeable with respect yto said expansion chamber and a tire to be inflated.
