IJTGZrZa gPg JACK.
To all whom it may concern:
Be it known that I, EDWARD J. CARBERRY, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Jack, of which the followiiig is a specification.
The principal objects of this invention are to provide an electric or other car or vehicle with a jack so mounted and constructed that while ordinarily being carried in a position where it is entirely out of the way it will be so located that it can be brought into position for effective use in a most simple and convenient manner; to provide means whereby the same can be operated by hand or by power; to provide a construction in which the parts .cannot become separated'or easily broken in the ordinary operation of the vehicle or ack; to provide means whereby the slipping of the {wheels will result in giving the jack a firmer hold; and generally to improve the construction and operation of devices of this character.
I Reference is to be had to the accompanying drawg's, in which I Figure 1 is a central longitudinal sectional view of a portion of a car showing a jack mounted thereon and truc'ted in accordance with this invention, Fig. 2 horizontal sectional view of the same on the line inarily electric and more jacks which other cars are provided with are carried in the car under be carried to either end lift the body from the order to overcome the well-known inconvenience.
jacks in such a manner, and to profor-more efficient operation of the jack for serving purpose, I have provided means whereby a jack is ently but movably connected with the bottom car, automobile,'or the like in such position that can ra dilfbe placed in position for use in case of accident.
Ifl -tle form f the car is provided, preferably at the front 'ack, with a hanger-plate ilmhaving a bearing 11. his bearing is pivotally mounted a head 12 forming 5 the upper partof the jack. The bottom part 13 of the jack is connected with the head by a screw 14 in any i desired way. In the form shown this screw is mounted in the ordinary way in the bottom section of the jack, which has a counter-sunk opening to receive it, and is provided at the top with an annular groove 15, while I the head of the jack is provided with one or more pins 16 entering said groove to hold the jack screw in proper position in the head, and permit it to turn therein. When the screw is turned in one direction it is obvious that the head and bottom of of the invention illustrated the bottom I and Specification of Letters Patent.
. compressed air, or in any other desired way, is mounte any event is hung in bearings .4
On into registration the jaclr will be separated I I UNITED STATES arents ,O'FEIOE.

and the head lifted if the bottom bears on the ground as it is designed to do. If the screw is accidentally turned too far up so that it leaves the screw-threaded opening in the bottom of the jack, the end of the screw will be retained in the counter-sunk opening at the top. This prevents the screw from being entirely disengaged from the jack.
The jack screw may be operated in any desired way,
but it is preferably provided with a worm-wheel 17 which is designed to be operated by a worm I shaft 19. If this shaft is designed to be operated by power a motor 20, which may be operated by electricit on the shaft. The shaft in 21 which depend from the bottom of the car, and conse;
quently the shaft moves with the car body, and the" worm remains in mesh with the worm wheel during operation of the jack.
If it is desired'to operate the jack by hand,,the shaft is provided with a square end 22, 'on which a wrench may be placed to operate the shaft. This square end is preferably provided, even whenthe ihoteris us so that it can be operated I I aged as to be inoperative. i I In order that the jack may get a firm hold on the ground, its lower surface is provided with irregularities or corrugations 24. Furthermore, it will be obvious that ii upon the starting of the jack into operation afte it is placed in proper position therefor, the car or other vehicle should start to move, there will be a tendency to turn the jack on one of its corners. In order to pro-' vide for preventing slipping in case such an action occurs, one corner of the bottom of the jack is provided with additional corrugations or irregularities 25 to permit the same to get a firm hold even when tilted as-described by the movement of the vehicle. For the purpose of holding the jack in position where it will be out of the way during the ordinary use of the car or other vehicle, a bracket 26 is mounted in any convenient position and supported from the car bottom.. This bracket is provided with an eye 27, and the bottom of the jack is provided with an eye 28 adapted to come with the eye on jack is tilted up into the position indicated in dottedlines in Fig. 1. The jack is held in this position by means of a pin 29 passing through the eyes. Of course in this position the worm-wheel is drawn away irom'the worm. When the device is to-be used the pin is withdrawn and the jack may be lowered down in proper position for operation as indicated in the drawings. If desired the top surface of the head of the jack may be roughened to secure a better hold on the hanger-plate. While I have illustrated and described a preferred form of the invention, I am aware that modifications may be made therein within the scope of the invention 18 on a I the bracket when the I as expressed in the claims. Therefore I do not wish to be limited to the particular form shown, but
What I do claim is:
