SPECIFICATION forming part of Letters Patent No. 404,688, dated June 4, 1889.

Application illed March 23,1889.

To all whom it may concern:

Be it known that I, JAMES LYNNwooD DA- VIs, a citizen of the United States, residing at Kimberton, in the county of Chester and State of Pennsylvania, have invented a new and useful Improvement in Drays, of which the following is a specification.

My invention relates to an improvement in drays; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of a dray embodying my improvement, showing the skid or inclined track extended therefrom. Fig. 2 is a longitudinal sectional View of the same, showing the skid or inclined track and the body arranged in position on the dray. Fig. 3 is a top plan view of the same. Fig. a is a vertical transverse sectional vlew.

The frame A of the'dray comprises a pair of longitudinal-track boards B, having vertical side-boards C at their outer sides and cross-bars D, which connect the front and rear ends of the boards B. On the front end of the frame is arranged an elevated seatE for the driver, and in the side-standards F of the said. seat is journaled a transverse Windlassshaft G, which has an operating-wheel I-I at one end, and is provided with a ratchet-wheel I. A flanged pawl K is' pivoted to one of the seat-standards, and is. adapted to engage the said ratchet-wheel.

A pair of bolsters L are arranged transversely under the boards B and bolted thereto at the front end of the frame. The said bolsters are supported on transverse plates M, and under the latter is secured the upper section or member N of the iifth-wheel. The front axle O has the hounds P of the usual construction, the said hounds being supported on a pair of longitudinal semi-elliptic springs R, the central portions of -Which are bolted or otherwise secured on the front, axle. The rear ends of the springs bear directly'under the rear corners of the hounds and the front y ends of the said springs are connected by a semi-elliptic transverse spring S, the central portion of which is secured under the crossbar at the front end of the hounds. The lower Serial No. 304,399. (No model.)

member or section T of the iifth-wheel is secured on the central portion of the hounds, and the king-bolt U passes through aligned vertical openings in the cross-bars V of the fifth-wheel. A pair of blocks IV are secured under the track-boards B at a suitable distance from the rear ends thereof, the thickness of said blocks being equal to the thickness of the rearmost cross-bar D, and bolted to the under sides of said blocks and of said cross-bar by bolts X, which pass also through the boards B, are a pair of rearwardly-extending bars Y, the latter projecting a suitable distance from the rear of the frame and having their rear ends connected by a cross-bar Z. On the center of the rear cross-bar D is secured a chain A', which has Aa hook B.

C represents a skid or track, which com-v prises a pair of longitudinal track-bars D", having vertical side boards or Iianges E. at their outer edges, and cross-bars F', (two or more,) which have their ends bolted tothe track-boards D' by means of pivotal bolts G. The said skid or track is thus rendered flexible, and the same is adapted 'to be collapsed or narrowed in width, so that the track-boards D will come in contact with each other, and thereby the said skid or track may be placed on the cross-bars D of the truckfra1ne,be tween the boards B thereof, where it' wilfbe out of the way. At one end of the said skid or inclined track is a keeper G2, which is adapted tobe engaged by the hook B', and

thereby the said skid or inclined track may be secured on the truck-frame.

The rear axle H of the truck is provided with a pair of semi-elliptical springs I', which have their centers bolted on the said axle and have their ends connected under the trackboards B by means of suitable keepers K. The rear ends of the said springs are connected to the ends of a semi-elliptical spring L', the central portion of which is secured under the rearmost cross-bar D.

Vhen the skid or inclined track is extended from the rear end of the truck-frame, the front end of the said skid or inclined track is placed on the rearwardly-extending bars Y, with the front cross-bar F in engagement with the cross-bar Z, as shown.

The body or bed IWI of the truck, which may IOO be provided with side standards N' or with removable side-boards, if preferred, is mounted on trucks O', each of which comprises ashaft P and rollers R', secured to the ends of said shafts. The said shafts are journaled in blocks S', which depend from the body or bed. At the front end of t-he latter is a ring T', which is adapted to be attached to the rear end of a rope or chain U', which rope or chain is attached to and is adapted to be Wound or uncoiled from the Windlass-shaft.

The operation of my invention is as follows: In order to load the truck the skid or track is first extended from the rear end thereof and the body or bed is rolled down the said skid or track onto the pavement or into the store or Warehouse and is there loaded. The rope or chain is then attached to the said bed or body by means of the ring T', and by revolving the ivindlassshaft said rope or chain is Wound thereon and the bed or body is drawn up the inclined skid or track onto the truckframe. The skid or track is then collapsed in the manner before described and secured on the truck-frame.

It Will be understood from the foregoing that the bed or body may be loaded and uit loaded much more easily than is possible where the parcels or casks have to be taken to and removed from the truck, as in the ordinary manner. Moreover, myimproved dray is advantageous in this respect, that fran gible articles placed therein are notu so likely to become broken.

Having thus described my Iinvention, I clainrl. The combination, with a wagon-frame provided with opposite tracks, one arranged at each side thereof, of a skid provided with opposite side bars adapted to register in width with the side tracks of the wagon and loosely connected to be collapsed laterally and adapted to be inserted between the side tracks of the wagon, substantially as specified.

2. The combination, with a Wagon-frame provided with opposite side tracks, of a truck mounted for movement1 thereon, and a laterally collapsible and movable skid designed to fit Within the side tracks of the wagon and withdrawn and extended to register with said tracks, substantially as specified.

3. The combination, with the frame A, having the relnovably-extending bars Y, terminating' in the chanifered bar Z, and having the bar I), provided with chain A', terminating in the hook B', of the skid provided with the staple G2, adapted to engage with the hook and to rest upon the chamfered edge of the bar Z, substantially as specified.

LL. The dray having the body provided with the longitudinal track boards or bars l, the bed or body having the supporting' wheels or rollers, and the skid or inclined track comprising the side-track Vboards D', and the cross-bars l1" pivotally connected thereto, whereby said skid or inclined track is adapted to be collapsed, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
