PIU's A. ANLAUF AND FRANZ J. ANLAUF, or CURTIN, OREGON.

LOGGING-BUNK.

Application filed December 2, 1911.

T o all, whom it may concern:

Be it known that we, PIUS A. ANLAUF and FRANZ J. ANLAUF, citizens of the United States, residing at Curtin, in the county of Douglas, State of Oregon, have invented certain new and useful Improvements in Logging-Brinks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in logging bunks, and has for its object to produce a device of this character adapted for application upon logging wagons or cars, the same being provided with adjustable chock blocks for supporting the logs upon the car or wagon.

A further object of the invention is to produce a device of this character so formed as to prevent accumulation of chips, dirt or bark thereon, whereby the logs are prevented from moving longitudinally, which is common in other devices of this character.

lVth these and other objects in view, the invention consists in certain novel features o-f construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawings: Figure 1 is a side elevation of the device. Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1. Fig. 3 is a detail perspective view of one of the chock blocks, the locking pin being removed. Fig. 4 is a perspective View of one of the lockingv pins.

Referring to the drawing, the numeral 1 designates the bolster, the same consisting of a base 2, said base being provided with perforations 3, and by which the bolster may be bolted to the car or wagon. Formed integral with the base 2, and extending longitudinally thereof is a vert-ical web 4, said web being provided at its opposite ends and adjacent the upper edge thereof, with a plurality7 of alined perforations 5, said perforations being tapered axially, the purpose of which will hereinafter be described.

A pair of chock blocks 6 is provided, each consisting of side plates 7, and a central spacing plate 8, the plate 8 being less in length than the plates 7 to produce a groove 9 for the reception of the web 4, whereby the blocks are adapted for sliding adjustment on said web. The plates 7 and 8 are formed with beveled edges 10, said edges Specification of Letters Patent.

extending throughout the length of those portions of the plates which extend beyond the upper edge of the web 4. By providing the beveled edges 10 the plates 7 and S are thus formed with vertical edges 11, whereby upon reversal of the blocks the vertical edges are confronting, thus adapting the device for use in connection with squared material, the normal position of the blocks 6 being as shown in Fig. 1, wherein the beveled edges 10 are confronting for holding the logs.

Formed near the lower ends of the plates 7 are perforations 12 and 13, said perforations being tapered axially, and arranged in registered relation,- the perforations-13 being slightly less in diameter than the perforations 1Q, whereby the tapered shank .14 of the locking pin 15 frictionally engages said perforations. The outer ends 16 of the pins are disposed at right angles to the shanks 14, the weight of the same causing said ends to normally hang downwardly, so that the projections 17 carried by the pins 15 may swing in the slots 1S formed between one side of one of the plates 7 and the U-shaped bracket 19, the ends of said brackets being rigidly connected to the plates 7 Each of the brackets 19 are formed with concaved recesses 20 and in which the shanks of the pins 15 rest.

Pivotally connected near the upper ends of the blocks 6 are loops 91, said loops being for the purpose of securing the ends of a binding chain or rope (not shown) for securing the piled logs, when necessary, and the load is too great to be held against accidental displacement by the blocks. Similarly connected loops 22 are provided, and serve to prevent loss of the blocks when one of the same is removed when unloading the logs, a rope or chain (not shown) having one of its ends attached to the loops, and its other end to the bottom of the wagon or car. To adjust the blocks 6 for different size loads, it is only necessary that the pins 15 be swung into the position as shown in dotted lines in Fig. 1, whereupon the projections 17 thereon will be in a position to be disengaged from the slots 1S, thus permitting withdrawal of the pins 15 so that the blocks 6 may be moved toward or away from each other and the perforations 12 and 13 of the plates 7 register with any of the perforations 5 formed in the web 4, the pins then being inserted in the registered perforations and the ends 16 thereof turned downwardly, thus preventing accidental displacement thereof.

That is claimed is:

l. rlhe combination with a bolster' havinga series of perforations formed therein, chock blocks slidably mounted on said bolster and provided with perforations adapted to register with the perforations of the bolster, U-shaped brackets secured to the blocks, aslot formed by said brackets, locking pins adapted to pass through the registered perforations, and means carried by the pins for engagement in said slots to prevent accidental removal of the locking ins. P 2. The combination with a ear or wagon, of a bolster comprising a base adapted to be secured to the car or wagon, a longitudinal web formed integral with said base, perforations formed in the opposite ends of the web, chock blocks provided with grooves adapted to receive the web, whereby said blocks are adapted for sliding movement Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents,

toward or away from each other upon the web, perforations formed in the blocks and adapted to register with any one of the perforations of the web, U-shaped brackets cured to the blocks and having concaved recesses, slots formed between the brackets and blocks, locking pins adapted to pass through the registered perforations and rest in said recesses, the outer ends of said pins being bent at right angles to their shanks, projections carried by the shanks of the pins, said projections being normally positioned in the slots to prevent accidental displacement of the locking pins, said projections being operable to disengage with said slots to Withdraw the locking pins.

In testimony whereof, We aflix our signatures in presence of two witnesses.
