SPECIFICATION forming part of Letters Patent No. 387,477, dated August '7, 1888.

Application iiledrApril 19, 1888. Serial No. 271,156. (No model.)

To all whom, it may concern:

Be it known that I, MANLY WILBUR, a citizen of the United States of America, residing at Seattle, in the county of King and Territory of W'ashington, have invented certain new and useful Improvements in Devices for Logging- Gars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theyy art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this.

being supported by a suitable truck. Fig. 2

is a plan view. Fig. 3 is a detail perspective view. Fig. 4 is a detail view of one of the links detached.

The frame or support to which my improvement is adapted to be applied may be used in connection either with a car-truck for transporting logs or upon a truck for carrying logs to a sawing mechanism in a sang-mill.

A refers to a beam, two of which are employed, each being provided on its upper edge with an angle-iron, a, upon which the logs will rest to hold them from longitudinal movement. The beams are secured to suitable truck-frames.

B and B refer to guide-strips, which are secured to the upper and lower edges of the beam A, so as to project outwardly therefrom to form slots in which the serrated bars G may move vertically. The serrated bar has its ends reduced to lie between these guides and the edge of the beam. The upper edge of this bar C is T-headed, the outer iange of which is serrated, as shown at c. To the T-head of the bar C is secured a sliding block, D, one edge thereof being beveled or inclined, as clearly shown in Fig. 1. The sliding block has pivoted to its lower edge, opposite the serrations, a pawl, e, which has an inward projection which engages with the serrations o, said pawl being held normally against the serrations by a spring, e. The sliding block D can be slid or moved upon the serrated bar in one direction by simply pushing the same; but to move it in an opposite direction it is necessary to elevate the pawl.

Suitably pivoted to the sides of the beam A are links E E, which are bifurcated at one end, as shown at f, and the sides thereof are recessed, as shown at f', so that when they are turned upon their pivots to lie horizontal, as

shown in dotted lines, Fig. 1, the connecting' bar will lie within said recesses to permit the serrated bar to be depressed sufficiently to allow the sliding blocks D to lie on a line or beneath the upper edge of the beam A.

The connecting-bar F is pivoted to each of the links and also to a trip-rod, G. This triprod is connected to a pivoted bar, H, the front end Aof which is recessed for the reception of the reduced end of the trip-rod and within 7 5 which the said trip-rod is pivoted. rlhis bar I-I is provided on its upper edge with a pin, which serves tohold in place a wrench or lever, I, for operating the same. The bar H is held on a line with the trip-rod, when the 8o links are elevated, by a spring-catch, h.

The attachment hereinbefore described is applied on each side of the beam A.

When it is desired to hold logs on the beam A, the lever or wrench I is slipped over the bar H to depress the spring h, and then by pressing the lever downwardly the parts are caused to assume the position shown in dotted lines, Fig. 1, the sliding blocks.D being below the vupper edge of the beam. Logs are then 9o loaded upon the beams, and the serrated bars. are elevated by moving the trip-rods and parts connected therewith to the position shown in A Fig. .1 in full lines, when the sliding blocks will be, moved above the upper edge of the beam 9 5 and can be slid upon the serrated bar to abut against the logs and prevent them rolling off the beams.

Having thus described my invention, I claim- 1. In combination with the beam A and serrated bar C, provided with adjustable slid- IOO ing blocks, links pivoted to the beam and connected to each other to be operated. simultaneously for elevating the serrated har, :1nd adjustable block carried thereby, substantially 5 as shown, and for the purpose set forth.

2. In combination with the beam A, guidestrips B B B B', vertical .moving bars held by said guidestrips and provided with suitable slidingr blocks, D I), iinks E, pivotelly secured 1o to the beam A and to connecting-bars F, and the tri p-rods G, pivotal] y secured to the ends of the bars H, the parts being organized substantially as shown, and for the purpose set forth.

3. In combination with a beam, A, a Ver- 15 tien1ly-movable serrated bar carrying sliding blocks D, links E, having the upper portions thereof bifurcated and one of the sides recessed, a connecting-bar pivotally secured to said links, und a trip-rod for operating the same, substantially as shown, and for the purpose set forth.

et. Incombinationwithacolnpoundtrip-rod, G, for the purpose set forth, a wrench or lever for moving one of the sections thereof, having abifnrcated heed, one member extending beyond the other and curved at its end to operate or depress a spring-catch employed for holding the trip-rod, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in o presence of two Witnesses.

MANLY VILBUR.
