It will be noticed that the side pieces 12 of the roll-frame are divergent rearwardly, so that the rear of the loading-space of the wagon is a little wider than the front thereof. By this construction the unloading is facilitated, inasmuch as thedivergencc toward the rear prevents any clogging, and consequently the lumber is permitted to pass freely olf the rear end of the wagon.

The roll at the forward end of the frame is indicated by the numeral 23 and the roll at the rear end of said frame by the numeral 24. These rolls 23 and 24e are adapted to revolve freely in either direction. I prefer that the bearings for the end journals of all the rolls shall comprise circular boxes 25, said boxes being formed with or carried by straps 26, said straps being secured to the upper edges of the side pieces 12 of the roll-frame. These several boxes contain a series of elongated antifriction-rollers 27. The journals of the rolls extend into these boxes and are surrounded by the antifriction-rollers. All the rolls are thereby enabled to turn with the greatest freedom, and the crank-handle is also permitted to be operated so as to positively rotate the fluted rolls with a minimum of labor.

The rear axle 10, instead of being cranked and dropping' below the frame, as is usual in this class of wagons, rests upon the upper edges of the side pieces 12 of the roll-frame and is secured thereto in any desirable manner, preferably by means of straps 2S passing over said axle and secured at their ends to the top edges of the side pieces 12. The longitudinal timbers 11 are converged toward the front of the wagon and are connected at their front converged ends by means of plates 29 29.

An important feature of my invention is the improved construction of the front truck of the wagon, whereby the front axle is disposed at such a low point as to enable the highest point of the peripheries of the front wheels to pass under the load, and thereby permit of a very short turning of the wagon in its loaded condition. Referring to this improved construction, the numeral 30 indicates an extension from the under plate 29 and which projects forwardly above the front axle S. 0n top of and secured to the front axle 8 is the axle-feed 31, and above the axle-feed is the front bolster 32. A king-bolt 33 passes through a strap 3e, extending' rearwardly from the hounds 35, and said bolt also passes through 4 the front axle 8, the axle-feed 31, and the bolster 32, the upper end of said king-bolt being provided with a head which bears against the upper edge or side of the bolster 32. The lower extremity of the king-bolt is threaded Q to receive a locking-nut 36, which is turned upon the bolt against the strap 34. ln order to permit the extension 30 of the plate 29 to pass or extend onto the upper side of the front axle 3. the axle-feed 31 should be recessed. This recess is indicated by the numeral 37, and said recess diverges rearwardly, l so as to permit the front axle to turn freely without binding. which would necessarily occur if the extension 30 of the plate 29 extended into a recess with parallel walls. It is necessary that the front truck of the wagon should be provided with a roller-bearing surface to permit the lumber or load to be readily shoved onto the wagon and rearwardly to the rear truck; but in view of the fact that the kingbolt in this particular construction extends upwardly through the front bolster 32 it is impracticable to employ a long single roller, inasmuch as in such event the extension of the upper end of the king-bolt through the bolster 32 would bc interfered with. Instead of employing a long` single roller on the front truck, therefore, I employ two short rollers 38 38, the end journals of which have their bearings in bearing-arms 39, extending upwardly from the bolster 32. Besides the connection formed between the front and rear trucks of the wagon by the extension 30 of the lower plate 29 l also provide a flexible connection consisting of a chain 40, which at opposite ends is connected to the bolster 32 and is then extended rearwardly to engage with a hook 41, secured above the upper plate 29. lThe fifth-wheel of the front truck is composed of the bearingplates 42 and 43, which are in bearing contact with each other, and the former is secured to the under side of the bolster 32 and the latter to the upper side of the axle-feed 31. By the improved construction of front truck above described it will be seen that the front rollers are carried at a sufficiently high point to support the load at such height that the front wheels 7 are permitted to pass under the load when the wagon is turned, and not only is the turning thereby provided for, but a very short turn is permitted. By this construction also the whole weight of that portion of the load above the front axle is directly on said axle.

In explanation of the advantages of my invention it is to be stated that in roll-ofi' lumber-wagons as commonly constructed in order to bringl the frame at a sufliciently low point the rear axle is cranked. rlhe crank formation of this axle necessarily compels the employment of a longer axle than is ordinarily used in wagons of this character, and this necessarily makes the wagon too wide for the standard loading-room reserved for that class of wagons, which is thirty-eight inches in the case of the standard narrow-track wagons of IOO IIO
