LIFTING-JACK FOB. CARS.

To all whom 2'15 may concern."

Be it known that I, SoLoMoN E. Amos, a citizen of the United States. residing at Charlestown, in the county of Suffolk and State of Massachusetts, have invented. new and useful Improvements in Lifting-Jacks for Cars, of which the following is a specificat-ion.

This invention relates toqneans for lifting a car from the tracks upon which it is supported.

The object of the invention is especially to provide a device which can be positioned quickly and used to raise a car body and its trucks from the track in case of accident of any kind, but especially in that class of accidents in which the body of a human ing is caught beneath the car.

The object of the invention is further. besides raising the car and its trucks from the track, to move the car along the track upon the means by which it'is raised or to move the car transversely of the tracks upon the device by which it is raised.

The invention consists in the combination and arrangement of parts set forth in the following specification and particular pointed out in the claims thereof.

Referring to the drawings: Figure l a side elevation of a portion of a car with my improved lifting mechanism attached thereto. Fig. 2 is a cross sectional elevation taken on line 2-2 of Fig. 1 illustrating a portion of the car frame in connection with my improved lifting mechanism. and also illustrating said lifting mechanism in dotted lines out of operative positimi.

Application filed May 13, 1912. Serial No. 696,817.

a similarly shaped hemispherical recess 19 formed in the under side of a bracket 20. A, shank 21 with a head 22 thereon extends from hemispherical portion 18 upwardly through a corresponding hole in the bracket 20, the function of said shank 2]. and head being to prevent the jack, as a whole, from dropping off of the bracket 20 when not in contact at. its lower end with the rail or other support. The bracket 20 is piv oted at 2-3 to a bracket 21 fast to the under side of the car body 5 and said bracket is held locked to said car body in the position illustrated in Fig. 2 by a pin 25 extending through ears formed upon a bracket 26 fast to the under side of the car body.

it will be noted that the shank 2. extends longitudinally of the upper member 7 and the bracket 20 is pivoted to swing about. a horizontal axis. while the pin 25 constitutes a iocking means to hold the jack in a ver tically disposed position. A strut .27 is pivoted at 38 between Q9 and is made in two parts 30 and scrcw-thrcadcd right and ft. res e5 ively. to engage similar jk' "cw-threat: in a nut 372 which is provide w h' a handle 33 by means. of which itmay be rotated. the end of the part 30 being adapted to project into the ground orinto a statioimry object or body. Said strut. 27 act when the parts are in the I )OSlilOIl ill ustrated in Fig. as a brace to prevent. the jack from mo in,:: transversely of the track 1'? during; the lifting of the car body. This an also be used to more the car across s in a jar is not in operative posito thr pcsilion illustrated in nes. i: g. :2. and held in thatlpov a I a l; pir tcd'at 3G to a braftket- In last to the frame of the car body. Apin 35-3 pa through the link 35 and through the eat. on the lower member 8 of the iack 6. \Vhen it is desired to use the jack a 'flfitl ful position. as illustrated l. the screw-threaded upper i 1.. ed by incansof a suitable bar inserted in holes 30 extending v of will upper inci'i'iber.

gether by tie-rods 40. Only one of the jacks is shown with the tie-rod as attached thereto, as illustrated i Fig. 2, but the other jack is a duplicate thereof located on the other track.

The periphery of the lower member 8 has a plurality of ears 29 arranged at different points around said periphery and the tierod 40 and strut 27 are adapted to be fastened to said lower member by pins 28 extending through said ears and through the ends of said tie-rod and strut. The lower member 8 is adapted to be rotated around the screw-threaded portion of the upper member 7 to a position at right angles to that shown in Fig. 2 i and illustrated in dotted lines and when in that position will be locked to the lower member of the other jack which rests upon the opposite rail by the tie-rod 40. The car can then be moved transversely of the tracks, after having been raised by means of the jacks, by rotating the nut 32 by means of the handle 33 and thus lengthening the strut 27, so that it will push the car, by means of the jacks, transversely of the tracks, it being understood that there is no strut applied to the other jack of the oppositely disposed pair of jacks on the other rail.

When it is desired to 'move the car when the jacks are in the position illustrated in Fig. 2, or to move the car longitudinally of the rails, then the strut 27 can be utilized, if desired, to move the car by changing its position and attaching the same to the ears 29 located on the left of the jack viewed in Fig. 1, and at that time said jack may also be tied to another jack on the same rail by a tie-rod 41., or, if suflicient assistance is at hand the car may be pushed by a number of passengers or persons who may be pres ent, with the rolls of the jacks resting on the rails and supporting the weight of the car and its trucks.

It is evident that when the upper members of the jacks are rotated to lift the car .body, the trucks of the car together with their wheels and axles would be lifted solely by the transom bolt of the truck, it such a thing were possible, but this would not be practicable and, therefore, in order to raise the trucks, with their axles and wheels, simultaneously with the raising of the car body, and in order to prevent the springs from expanding during this raising of the car body and the trucks, means are provided to lock the frame-10f the truck to the car body, as illustrated in Figs. 1 and 4. This means consists of a locking member 42 adapted to lock the truck to the car body and consisting of a rod 43 terminating at its upper end in a hook eta-adapted to be hooked into an eye 45 fast to the frame of the car body 5. This rod is screw-threaded to engage a nut 46 which has a handle 47 thereon by means of which it may be rotatcd, the lower end of said nut being screwthreaded in the opposite direction from the upper end to engage a corresponding screwthread upon a rod 48 extending upwardly from a U-shaped bracket 49 which clasps the lower frame 50 of the car truck 51. This bracket is held upon the said lower part of the car frame by a pin 52. By this means the frame of the truck may be locked to the car body and will be raised by said car body by means of the jacks hereinbefore specifically described, all in a manner which I will now proceed to describe in general.

When it is desired to raise the car from the tracks and to move the sanie'iongitutlinally of the tracks away from the body which may be underneath the trucksor car body, the jacks are swung down from the position shown in dotted lines, as in Fig. 2, by removing the pin 38 and allowing the jack to swing, together with the bracket 20, about the pivot 23 to the position illus trated in Fig. 2, with the jack in a vertically disposed position. The locking pin 25 is inserted through the ears'of the bracket 26 and through the bracket 20, looking said bracket in the position. illustrated in full lines, Fig. 2. The jack on the opposite rail is placed likewise in a vertically disposed position and the two are joined together by the tie-rod 40. The locking members 42 are hooked into the eyes 45, the U-shaped braekets 19 are thrown into engagement with the lower portion of the truck frame andare locked thereto by the pins The nuts/i0 in each case are then rotated, by means of their handles 47, until the truck frame is locked to the car body by said locking device. The upper member 7 of each of the jacks is then rotated by a suitable rod placed within the holes 35) and the car body, to' gcther with the trucks and their axles and wheels will then be raised from. the track to any desired extent. The human body which is beneath the car body or beneath the trucks can then be removed and the operations hercinbetore descri ed are reversed and the jacks are thrown back into the positions shown in dotted lines, Fig. 2, while the locking members 42 are removed from the trucks and car body and stored n a convenient place. i

lf it is desired to mow the car longitudinally of the track. the ticro ls 41 are conmooted from one of the jacks to another on the same rail and then the car is moved, either by pushing it by means of a number of persons or by pushing it by means of the strut rods 27 which are connected to the jacks as hereinbefore described and upon rotating the nuts 32 of said slut rods, by means of their respective handles 33. said strut; rods will be lengthoimi so as to move the car longitudinallyof the track.

if it is desired to move the -ar transversely of the tl'tltliS after having been raised. then the lower members of the ja ks.

are rotated to a position at right angles to that illustrated in Figs". 1 and the oppo sitely disposed 13th.; are tied together by the tie-rods 4t) and 41 and the ear is moved by 1). will rest thereon and then the ear ran be pushed ahng: the transversel extending timber to any extent desired. The ear in this instance can be pushed bodily by a mini ber of persons pushing direetly on the ear. or the same ran be moved by means of the strut rods 1T attat-hed to the lower member of the two jarrlts on the same rail. and lo rated in the position of the strut rod illn trated in Fly. '2.

To plaee the car on the track again. it can be moved in an opposite direction in a similar manner and the operations hereinbefore deseribed reversed. so that the jacks can be utilized to lower the car and its trucks. bringing the Wheels of the trunks into engagement with the rails and subsequently removing the tie-rods 40 and 41 and the strutt rods 27. swinging the jaeks into their dotted position illustrated in Fig. 2 and locking the same in said dotted position by means of the pins 38.

This evident that if desired the rolls 10. t1 and 12 may be removed from the jark by removi the pins 13. 14 and 15. respeetively. and the lower part of the jaek will then rest directtv upon the rail instead ot said rolls eontaeting therewith.

It. is evident that without departing from the spirit of my invention the part 43 might terminate in an eye and the part 45 be made as a hook. sat-h a oonstrn tion being merely a reversal of the construetion shown in Fig. t W-itliOllt set-tiring any difi'erenee in tunetion.
