TRUCK JACK.

Application filed October 27, 19l9. Serial No. 333,682.

To all wiz om t may concern ing is a specification.

Our invention relates to a truck-j ack adapted for moving relatively large and heavy objects, such, for ex tractors or the like.

ample, as farm The principal object of the invention is the provision of a suitable and improved apparatus of the above character which will expedite the loading of farm tractors into railway cars ready for shipment, by providing an inexpensive truckjack with which the tractors may be readily sitioned in the railway car, so that the maxi- .ofthe frontend of the apparatus.

and quickly pomum shipping space of the car may be used and also minimize the labor and expense incident to the performance of this work.

When shipping certain tractors, it is customary to p types of farm osition the tractors closely together transversely of the car so as to economize in shipping space. This-arrangement presents certain disadvantages in loading and unloading ofthe tractors, due to the tractors 4being of substantially vthe same length as the interior width of the car, and

ytherefore requiring the tractors to be'skidded longitudinally of the car to their proper position The irregularities of the car floor,

the weight of the tractor, and thesharp elements on the tread of the tractor wheels make this manner of positioning the tractors very laborious and undesirable. f In order to overcome these and other incidental objections, the invention contemplates a lsmall truck apparatus which may 'be readily .and

conveniently positioned under Vthe body cfa tractor, whichtruck is provi ded with ten ielevating device that may be easily maniplated to raise the tractor off the floor Aof thecar,

whereby it may loe readilymoved to dei sired position.

The invention consists in the Anovel arrangements, 'constructions and combinations ofpartshereinafter described and claimed for carrying out the above vstated olojecta and such other objects as In 'theffollowing description-` .table in its raised position;

fwitli relation to the floor. This table Yis Vformed with'side : walls 19, 19, Vthe `lovver edges 2O of which are 'formed with a taper The preferred embedmept ef 0er ievenf 55 f tion is illustrated ip the eeeerepeeypg .direte `tion Fie e is e freementery pler1 View. illitetrating the means for locking'the elevatip'g Fig; 5 is a sectional view taken on line wof Fig. 3y .Figi 6 ie ,e ereee-eeeeenel View teken en lille fef'Fg-; endl i A Ffa` 7 .ie e fragmentary View in elevetep .Like ehereefere efreterenee deegpefelkfe parts r throughout the severalgures of the drawings. f

Referring to the drawings, lour preferred construction consists of a framecasting lO supported a generally inclined position on rear wheels l1, l1, journaledon trunnions 12,"12 at yopposite sides'of the frainaandha centrally positioned free,t Wheel*13a The ,front Wheel is mounted ip the erl .114 which is revolu'bly connected to the frame "a .vertical stud l5 on the fork in an integral peering 1G ferme@ et'theeepfe'r ef the' frame at the forward end 17 thereof. table 18 isslidably supported on the in- '.clined `side wallsof the frame 10, Zand "is adapted when moved toward Vthe front end of thefra'meilO to be `gnrtorn atically elevated i' eor'reepeedee te .the inclination ofthe upper 4edge' eflthefreme, S0 @het the Uppe ,edge ef "these side ywalls. will b e' maintained `in a'sub- 100 etehtelli lierjzolltel peSitiQn-.When the table ismo .ed from one pOsitionto/another. ,Any

appreciable `lateral movement of tliejtable'ilS fwith relation'y yto 'the frarne'mlO i is .prevented by''meanfsof a central reinforcing`rib21 on 195 the frame which lits between ears 22, 22,

on the forward end23 of table,

forme'don the under surface of the bottom 26' adjacent the rear end of the tablee The reinforcing rib 21 is provided with a taper vsubstantially the same as the side walls of the" frame, so that this rib will serve as a guide-*for the table 18 throughout the entire travel thereof. rlhe table 18 is operatively7 connected by means of links 2T, 27, with the tongue designated generally at 28 and shown as pivoted between ears 29, 29 on bearing 18. The said links are connected to the carriage byV` a pin 27??.,extending through them and the years 22, and are connected to the tongue as indicated at 30 a short distance from the pivot pin 31, so that by forcing the tongue 4down from the position shown in full lines in the drawings toa horizontal position, the table 18 will be moved upwardly on the inclined surface of the frame 10 so'as to elevate the sameto the position shown in dottedY lines in Figs. 2 and 5. The table may be locked in its elevated position by inserting a pin 32 into openings 33 in the links 27, 27, so ythat ythe pin will stand in front of an upstanding boss34 formed on the frame 10 at the forward endof the rigidifying rib 21 V(Fig. 4). The pin 32 is preferably secured to the frame by a chain 85, so as to avoid the .possibility of itsbeing lost or misplaced. The tongue 28 is preferably formed in two parts, 36, 37,` which lare joinedtogether with a lpivotedconnection las indicated at 38, so as'to permitthe upper part 37 to be folded back over the truck jack when the same is not in use. This portion of the .tongue yis preferably provided with a lip 89 which extends under the lower edge of the lower portion 36 when the tongue is in its extended position. The tongue sections may be firmly lsecured in their extended position by inserting ai locking pin 40 into registering openingsv41. This pin is likewise secured to the apparatus by means of a chain or other suitable attachment.

The upper edges of the side walls 19, 19

vof the ,table 18 are preferably formed with central recesses 42 in which the object de- Asired to be moved. is supported. The truck jack illustratedin the drawings is designed particularly for use in connection with the 4.moving ofiFord tractors from one place toV 'A another-,though .it will be obvious that it is not .limited to .this particular use.

|YVhen it `is desiredto move `a Ford .tractor .from one `position tol another, such for` exam- `plewas when moving it from apoint adiacent the door opening of a box car ftoeither v(end thereof, the truck jack is arranged in a su1tableposition under the body of the trac- `torandthe table Velevated until the tractor Y I,yvheels43,7.l 44are raised a short distance off .theloo'nl ,In order to accomplish this re- A,su-lt, Vitis-necessary to .so position the truck jack underthe tractorbody that the weight of the tractor will be balancedv on the truck jack. rlhe under surface of the body of these tractors, having an irregular contour, necessitates the use of a suitable device for maintaining the tractor in a substantially horizontal position'when it is Vraised off the oor. In order to accomplish this result one of the sides 19 of the table 18 is positioned under the transmission casing 45 ofthe tractor, as shown in Fig. 1, and a removable supporting element 46 is positioned under the crank casing of the engine. This removable element, is preferably provided with upstanding-legs- 47, 48, which extend on oppo siteV sides of the engine crank casing 49 and hear against the underside of the flange 50 thereof. In order to prevent this attachment from shifting while the tractor is being elevated, the attachment is provided with lips 51 which tit over opposite edges of the table 18. i

During the raising movement of the tractor, it `will be noted that the tractor, being much heavier than the truck jack, will cause the truck jack to move backwards to the pcsition shown in dotted lines in Figs. 2and 5.

The fork 14 in which the forward wheel is journaled is provided with a boss 52 havf ing a bore adapted to receive a removable rod 58, which rodprovides a suitable steering lever for turning the fork 14 from one position to another, so as to properly direct the truck `jack in the course desired. It will lbe noted that byforming each of the end walls19, 19,7of the table 18 with corresponding grooves 42, 42, and by making the supporting brackets 46 Vreadily detachable from 1.
