BOLSTER FOR LOGGING-CAR FRAMES.

SPECIFICATION forming part of Letters I'atent No. 623,733, dated April 25, 1899.

Apnlicationfiled October 14, 1898. Serial No. 693,500. (No model.)

To all whom it may concern: Be it known that I, SURRY PARKER,Of Pine town, in the county of Beaufort and State of description.

The object of the invention is to provide a new and improved bolster, more especially designed for use on logging-cars, and arranged to permit of conveniently loading or unloading cars without lifting the logs over the standards or requiring entire removal of the standards and loss thereof, as is so frequently the case with standards now used.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of the improvement as applied, and Fig. 2 is an enlarged transverse section of one end of the bolster.

The logging-car on which the improvement is applied is provided with the usual frame A, on which are secured transversely-extending bolsters B, each of which supports at one end a standard 0 for holding the logs in place on the bolsters. Each of the standards 0 has its inner upper end beveled, as is plainly indicated in the drawings, and the standard is fitted to slide vertically in an opening or bearing B, formed vertically in the bolster. (See Fig. 2.) The lower portion of the standard 0 is formed with an elongated slot 0 engaged by a pin D, secured in the bolster B, said slot being so arranged that when the standard is in a lowermost position, as shown in Fig. 2, then the pin engages the upper end wall of the slot and the extreme upper end of the standard is flush or below the top surface of the bolster B. The slot 0 is of such length that when the standard is pushed upward by the operator and the upper beveled end extends above the top surface of the bolster then the pin is at or near the lower wall of the slot, and a transverse opening 0 in the stand ard appears just above thetop surface of the bolster to receive a locking-pin E, adapted to rest on the top surface of the bolster B outside of the standard, as is plainly indistandard 0 to move downward into a lower-- most position by its own gravity to permit of conveniently removing the logs from the bolster or of loading the logs upon the bolster without being compelled to remove the'standards from the bolster or to lift the logs over the standards.

It is evident from the foregoing that the standards always remain on the bolsters and can be readily lifted into an extended position and locked therein, as described, to retain the logs in place, or be released to permit of lowering the standards for removal or loading of the logs, as before described.

I do not limit myself to the special construction of the locking device for retaining the standards in an uppermost or extended position, as it is evident that other devices besides the one shown and described may be employed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent+.

1. A bolster provided with a standard movable on the bolster, and extending above the surface thereof when in use and below the top surface and out of the way when loading or unloading, and a retaining device for holding the standard on the bolster and for guiding the standard in its up-and-down movement and for limiting the sliding movement, substantially as shown and described.

2. The combination with a bolster provided with a vertically-disposed bearing, of a standard fitted to slide up and down in said hearing and formed with a vertical slot, a pin in said slot and secured to the bolster in the said bearing whereby to guide the standard in its up-and-down movement and to limit such movement, and means for holding said standard in its raised position, as and for the purpose set forth.
