JOHN A. DANIELSON, OF CALUMET, MICHIGAN.

TIMBER-BUNK.

SPECIFICATION forming part of Letters Patent No. 363,608, dated May 24,1887.

Application filed March 9, 1887.

To aZZ whom it may concern:

Be it known that 1, JOHN A. DANIELSON, of Calumet, in the county of Houghton and State of Michigamhave invented a newand Improved Log and Timber Bunk, of which the following is a full, clear, and exact description.

This invention relates to a simple, cheap, durable, and exceedingly efficient log or timber bunk that is applicable for use in connection with a sleigh, wagon, car, or any other vehicle 0r conveyance upon which timber or logs are to be transported.

Reference is to be had to the accompanying drawingsfiorming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a View of a portion of a sled representing the same as being provided with my improved form of log or timber bunk. Fig. 2 is a side View of a portion of the bunk; and Fig. 3 is-a crosssectional view taken on line a: x of Fig. 2.

In constructing such abunk as the one forming the subject-i'natter of this application and illustrated in the drawings above referred to, I provide a cross bed-beam, 10, to which there is bolted or otherwise suitably connected a double angleiron, 11. Upon this double angle-iron there are mounted two sliding blocks, 12, which said blocks are formed with downwardly extending. side 'flanges, 13, that fit against the web of the double angle-iron 11, which said web is formed with a number of apertures, 2, through which there is passed a retaining-pin, 3, that is carried by a chain, 4, said chain being connected to the block 12, the arrangement being such that the blocks 12 may be moved toward or from each other and se cured in such position as may be required to properly support the load. In order to prevent the loss of the blocks 12, they are held to the timber 10 by chains 5, as is clearly shown in Fig. 1.

Two of the bunks described are mounted upon vehicles or conveyances to be used in transporting the logs or timber, and when the timber or logs are loaded upon the bunks one of the blocks 12 from each of the bunks is removed. After the timber is loaded the blocks are adjusted to such a position as may be re Serial No. 230,229. (No model.)

quired to properly support the load, and, if

desired, binding-chains may thrown-over the load and brought into engagement with swinging rings 16, that are carried by the blocks 12.

The advantages arising from the use of such a logbunk as the one above described will be readily appreciated by those who have had occasion to use the imperfect form of bunk heretofore employed, for with my improved construction I not only dispense with the use of bolster-blocks, but I prevent the slipping of a log from the bunk when such log has been thrown on at an angle and it is desired to Straighten it up.

I am aware that adjustable standards for. wagon-bolsters have heretofore been employed, and do not broadly claim such device.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a bed-beam with a double angleiron, of blocks formed with downwardly extending flanges, which fit against the web of said angle-iron, and pins arranged to pass through said downwardly-extending flanges and transversely through apertures formed in the web of the angle-iron, substantially as described.

2. In a log-bunk, the combination, with the bed beam, of a double angle iron carried thereby, blocks having links 16, and connected to the bed-beam by chains and mounted to slide upon the double anglc-iron,and retainingpins arranged in connection with the blocks, substantially as described.

3; In a log-bunk, the combination, with a bed-beam, of a double angle-iron, 11, formed with an apertured web,blocl s 12, having downwardly-extending flanges 13, which fit upon either side of the web of the double angle-iron, chains'5, secured to the bed-beam and to the blocks, pins 3, passing through the flanges 13 and the web of the angleiron, and chains 4., by which the pins are held to the block, substantially as described.

JOHN A. DANIELSON.
