LUMBER-WAGON- Specification of Letters Patent. Application filed March 2, 1906. Serial No. 303,887.

Patented March 12, 1907.

T5 all whom, it may concern:

Be it known that we, SILAS J. LONOKS and WILLIAM M. HoLooMB, citizens of the United States, residing at Blanchard, in the county of Sevier and State of Arkansas, have invented certain new and useful Improvements in Lumber-Wagons, of which the following is a specification.

Our invention contemplates certain new and useful improvements in lumber wagons, and particularly improvements in bunks and chock-blocks therefor.

The primary object of our invention is to provide an improved construction of bunk and chock-block whereby the chock-blocks may be adjusted lateral y, so as to accommodate the width of the log-receiving portion of the wagon or sled to logs of different sizes and number and whereby the chock-blocks may be turned downwardly overthe ends of the cap-pieces of the bunks, so as to be out of the way when unloading and loading.

A further object of the invention is to provide an improvement of this character in which the chock-block is provided w th mproved means whereby a skid may be readily attached thereto for use in loading and unloading; and a further object of the invention is to provide an improved construction of bunk and chock-blocks for lumber-Wagons or sleds in which improved-means are provided for 'maintaining the chock-blocks in different laterally adjusted positions for maintaining said blocks in position down over the ends of the cap-pieces of the bunks and in skids provided with improved means whereby they may be attached to the chockblocks when the latter are in said lower position.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a top plan view of a lumberwagon embodying the improvements of my invention. Fig. 2 is a side elevation, with parts in section, of one of the bunks embodying said improvements, the chock-block be- -ing shown in position down over the end of the cap-piece of the bunk and a'skid being shown secured to said chock-block. Fig. 3 is a similar view without the skid, showing the chock-block in a different position. Fig. 4 is a detail perspective view illustrating the 1 different parts of the chock-block and the means for holding the same in its different laterally-adjusted positions.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a lumber sled or wagon, a wagon being herein shown for the purposes of illustration only.

2 designates the bunks or transverse bolsters that extend across the front and rear of the wagon to support the ends of logs, and 8 designates the cap-pieces for said bunks, the same being preferably secured to the bunks by screws 4, as shown. Transversely-extending slots 5 are provided in each bunk, said slots being in the present instance formed by recesses out into the lower sides of the cap-pieces, and preferably one or both walls of these slots are lined with metal strips 6, as shown. In the present instance these metal strips extend not only along one side and two end walls of the recesses in the cappieces, but also extend along the under face of each cap-piece and coact with metal blocks 7, partially embedded in the upper surface of the bunks proper, so as to secure a rigid structure. Within each of the slots'5 there projects a longitudinally-extending series of locking-teeth the catches 8 of which are preferably formed on the metallic strip 6.

Locking bolts or pins 10 are mounted to slide within the slots 5 and are each provided at one end with a handle or lever 11 for turning the same. Each pin 10 is provided at one side with a recess 12, which when drawn into registry with the locking-catches 8 may pass the same or when the pin is turned, so as to carry the recesses out of registry with the catches, prevent the pin from being shifted in its respective slot. Preferably the handle or lever 11 of each pin is so arranged with respect to the recess 12 thereof and the lever is so loosely mounted that when the handle swings downwardly by its own weight the recess will be carried out of registry with the series of catches, so that the pin will be automatically locked in any desired position.

A chock-block 13 is mounted on each of the pins 10. Each of these chock-blocks preferably comprises a metallic structure of yoke formation, embodying two side arms 14, which embrace thecap-pieces 3 andwln'oare apertured to receive the opposite ends of the pin 10, on which they are thereby preferi ably mounted, so as to permit the chockl blocks to rock back and forth in a vertical plane over the upper surface of the cappieces. Each chock-block also embodies a cross connecting member 15, which is in the form of a flat plate extending, preferably, at right angles to the arms '14 and which is provided with an angular edge 16, designed to rest upon the top surface of the cap-pieces, and with an oppositely-extending angular edge 17, designed to support the block in position down over the end of the bunk, as shown in Fig. 2, and which is further provided with a slot 18, designed to receive a hooked end 19 of a plate 20, secured to one end of the skid 21.

In practical operation the chock-blocks 13 of that side of the wagon or sled from which it is intended to do the loading, for instance, are moved outwardly and turned down over the outer ends of the bunks, orrather the cap pieces thereof, with their inwardly-bent edges 17 supporting them on the upper surfaces of the cap-pieces, as illustrated in Fig. 2. The skids 21 are then hooked in the slots of the chock-blocks, as illustrated in said view, and the wagonis then loaded in a manner that is manifest. After the log or logs have been rolled onto the bunk up against the opposite" chock-blocks the chock-blocks at the loading side'of the wagon may then be slipped forwardly up over the ends of the cap-pieces, with their edges 16 resting upon the upper surfaces of the cap-pieces. li'orward movement of the said chock-blocks is permitted by turning the handles or levers 11 so as to bring the recesses 12 into registry with the catches 8, and as soon as the chockblocks have been moved forwardly far enough the levers 11 are dropped and swing to their I lower position, in which the recesses 12 are out of registry with the catches, and the pins D maintain the chock-blocks at their adjust- .ed positions.

From the foregoing description, in connection with the accompanying drawings, it will be seen that we have provided an improved construction of bunk and chock-blocks therefor whereby the latter may be adjusted read ily to different lateral positions along the bunks, so as to accommodate a log or a plurality of logs of different widths or diameters and whereby the chock-blocks at either side of the Wagon or sled may be readily slid outwardly and down over the ends of the bunks, where they will sustain themselves in position for the convenient attachment thereto of skids for the loading or unloading .of the wagon or sled.

Having thus described the invention, what is claimed as new is 1. In a device of the character described, the combination with a bunk of a swinging j chock-block laterally adjustable thereon and comprising side arms embracing the upper side of the bunk, and a connecting cross member adapted to rest and slide upon the upper surface of the bunk whereby to hold the side arms in angular position with respect to said upper surface, and means for holding said chock-block at different lateral adjustments with respect to the tongue, the cross connecting member being provided at its upper surface with means for engaging the end of the bunk whereby to support the chock-block in suspended position down over the end of the bunk.

2. The combination with a bunk, of a swinging chock-block laterally adjustable thereon and designed to be moved out over the end of the bunk, said chock-block comprising a pair of side arms embracing the upper side of the bunk and a cross connecting member provided with an outwardly-turned lower edge 16 and an inwardly-turned opposite edge 17, the first-named edge being adapted to rest upon the upper surface of the bunk and slide along the same, and the other, inturned edge, being adapted to engage with the end of the bunk for the purpose specified, and means for holding the chock-block at different lateral adjustments with respect -to the bunk.
