, FORE-TRUCK.

To all whom it may concern Be it known thatl, JACKSON 0. Harms,

a citizen of the United States, and a resident of Mountpleasant, county of Maury,

and State of Tennessee, have invented certain new and useful Improvements in Fore- Trucks, of whlch the following is a. spec1ficat-ion.

more particularly to fore trucks used in connection'with wheeled scrapers, and other animal drawn wheeled applianc'es,l an object being to provide a simple, cheapand an erlicient device whereby undue strain will be taken from the draft animals neck and shoulders, and also permit short turning on all conditions of land.

\Vith this and other objects in View, my invention consists in certain novel features of construction, arrangement and combination of parts as will be hereafter fully pointed out in the specification and claims, reference being had to the drawing forming a part hereof,in which, 7

Figure 1 is a top plan view of my improvements as applied;

Fig. 2 a front elevation of same;

Fig. 3 is a top plan View showing the truck turning and the relative arrangement of parts in that position;

'Fig. 41- is a vertical section taken online l-d of Fig. 1.

In carrying out my invention, the fore truck comprises essentially a frame consisting of upper and lower cross beams 10 and 11 made of metal and intermediate beams 12 of less length than the top and bottom cams, and diagonally disposed braces 13 at each end which meet at about midway between the upper and lower beams, leaving a space'at each end in which the upright posts l t of stub axles 15 are pivot-ally held between the ends of the upper and lower beams. The stub axles 15 have mounted to rotate on them the wheels 16. Each stub axle has ro'ectin rearwardl an arm 17 the rear ends of which are pivotally connected between the ends of a pair of links 18. As shown the upper and lower beams 10 and 11 and the intermediate beams may be.

made integral or theymay be in separate pieces and rigidly connected together at the ends. but the several beamsare to be so spaced from each other as to permit the in.-

hily invention relates to vehicle trucks and which is held between said beams by a bolt 20, which passes through all the beams at the center of the truck, the rear end of the short reach 19 is bolted to the upper end of abent rearwardly extending brace 21 the forward end of said brace 21 being held to the lower beam by the bolt 20 before mentioned.

bottom beam 11 and at the apeX of the angle to the rearwardly extending brace 21, 1 as plainly shown 1n'the drawings.

.Pivotally mounted between the intermediate beams 12 is the rear member 23 of limber tongue and to the forward end of this vmember, the draft tongue 24, constituting v the remainder of the limber tongue, is

pivotally mounted, as shown at 25 by a knuckle joint, so that thedraft tongue may swing vertically above and below the plane of the rear member 23. V

tending rearwardly has its rear end pivotally mounted between the pair of links 18, by a bolt 26, as shown in Fig. 4.

When the truck is used with a wheel scraper, the hounds of the scraper are attached to the foretruc-k in the following manner: The bolt 27 which secures the rear end of short reach 19 to the bent brace 21 is sufficiently long topermit its use when the cross beam-28 of the hound structure is connected to the end of thefbrace and said reach; the forward members 29 of then hounds converge and have extensions extending along the sides of the reach between the top beam and the upper intermediate beam 12, and are held in place by bolts 30 passed horizontally through said ends and through the short reach'19.

The intermediate beams 12'are maintained spaced apart by connecting pieces or blocks 12 which have their inner or opposed faces beveled as indicated at 12 so that the tongue member 28 may be swung to its limit laterally and contact with an oblique surface instead of striking a sharp corner and thus prevent breakage ofthe tongue.

When the draft team is swung to either side, I the tongue member 23 being Qpivoted: at 20 sw ngs between the intermediate beams to the corresponding side and the rear-end of" said tongue member 23 being pivotall r secured between the links '18, at theircenter 1 cause the links to move lol'igitudinally in V the oppositedirection to the turn, and the ends of llllkS 18' are plrot'ally connected to the rearwvardly extending arms of the said axles causing the Wheels. to swing close to the front and rear of the front beams ot the truck, the beams const1tut1ngasa Whole a bolster; Byvn'tuejof thepartic ul-an me'unting and 17 ,a parallelogram is formedwhich will I have-right or oblique angles, accordingly as the truck is being drawn straight ahead or 20 swung to either the right or left.

The short Wooden reach, 'the'hounds, and the braces, which are rigidly connected to- 'gether and. which are coupled to the "YWheeledQ scraper are maintained against a at all times.

swingingmotion either to the right or left Should the draft animals go into a depression'or the foretruck or scraper drop into a depresslon or strike an elevation, the hmber-tongue by virtue of its omted nature- Will remain in the same position with respect to th team, and thus'no extra strain or pull Wlll be put onthe sides or shoulders of the animals. This is a very important result of the peculiar construction and arrangement or" the parts of this invention as ordinarily in the use of Wheeled scrapers, the pitching and twisting of the structures due to uneven condition of the ground being worked causesgdangerous and disabling sores, and henc'e' curtails usefulness ofthe team.
