LOG-CAR STANDARD.

SPECIFICATION forming part of Letters Patent No. 770,974, dated. September 27, 1904.

Application filed July 21, 1904 Serial No. 217,558. (No model.)

To ctl whom it may concern.-

Be it known that I, MILES D. LIVERMAN, a citizen of the United States, residing at C0- lumbia, in the county of Tyrrell and State of North Carolina, have invented a new and useful Log-Car Standard, of which the following is a specification.

My invention relates to logging-car standards, and has for its objects to produce a comparatively simple inexpensive device of this character wherein the standard will be securely locked in log-retaining position and will when released swing automatically to an unobstructing position, thus permitting free unloading of the car.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is an end elevation of a car having my improvement applied thereto. Fig. 2 is a sectional plan taken on the line 2 2 of Fig. 1. Fig. 3 is asectional elevation on the line 3 3 of Fig.2.

Referring to the drawings, 1 designates the I car, which is of the usual or any appropriate construction and material and is provided with a bolster 2, there being, of course, a plurality of these bolsters upon which the logs rest when the car is loaded. The bolster 2 has formed at each end a vertical longitudinal slot or recess 3 and a horizontal slot or recess 4, constituting guideways or seats which extend inward suitable distances from the outer end of the bolster, there being pivoted Within the primary seat 3 by means of a horizontal bolt 5, extending wholly through the bolster transversely, a log-engaging member or standard- 6, preferably composed of strap metal and of substantially L form, as shown, While within the secondary slot or seat 4 there is pivoted for horizontal swinging movement a locking member or bolt 7. When in its active log-engaging position, the standard 6 contacts with a stop or abutment 8, formed of a metal plate or strap extended transversely across the upper face of the bolster and having a, slot or seat 9 formed partly therethrough transversely for the reception of the standard, which latter when in its inactive or releasing position contacts with a stop or abutment in the form of a strap 10, extended transversely across the lower face of the bolster, the straps or plates 8 and 10 being secured in place by vertical rivet-bolts 11, upon one of which the locking member 7 is pivoted and the other of which constitutes a stop within the recess 4 and against which the member 7 abuts when in looking position. The standard-pivoting bolt or axle 5 has further pivoted thereon, at one side of the bolster an engaging member or hook 12, designed for engagement with the adjacent normally free end of the locking member 7 to maintain the same in looking position. The bolt 7 in moving to and from looking position overrides a wearing member or plate 13 in the form of a length ofstrap metal bent or folded around the end of the bolster longitudinally and retained in place by one of the rivet-bolts 11.

In practice the standard 6 may be swung upon its pivot to active or log-engaging position and secured by means of the bolt, which when in looking position extends transversely of the bolster within the recess 1 and beneath the then lower horizontal edge of the standard, it being observed that the edge of the standard which is engaged by the locking member is slightly curved downwardly and inwardly, whereby as the locking-bolt passes thereboneath the standard will be forced upward tightly against the abutment 8. \Vhen, however, the locking-bolt is swung to releasing position, the standard will move by gravity to its inactive position (illustrated in Fig. 3) and rest in contact with the abutment 10. It is to be particularly noted that when in its inactive position the standard will be so nearly housed within the slot or recess 3 as to offer no obstruction or hindrance to the free unloading of the logs from the car.

It is apparent from the foregoing that I produce a strong and durable device of simple construction and operation and one which will in practice sufficiently perform its functions,

"it being understood that minor changes in the details herein set forth. may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed is v 1. In a device of the class described, a bolster havinga pair of intersecting slots, a standard pivoted in one of said slots for movement to active or inactive position, a locking member movably disposed in the other slot for engagement with the standard to maintain the same in active position, and a retaining member designed for engagement with the locking member to maintain the same in locking position.

2. In a device of the class described, a bolster having a pair of intersecting slots, a standard pivoted in one of said slots for movement to active or inactive position, a locking member pivoted in the other of said slots and adapted to swing beneath the standard for maintaining the same in active position, and a retaining-hook for engagement with the locking member to secure the same in looking position.

3. In a device of the class described, a bolster having intersecting slots, a standard pivoted in one of the slots for movement to active or inactive positions, stop plates arranged across said slot for limiting the movements of the standard, a bolt for securing said plates in place, and a locking member pivoted on the bolt within the other of said slots and adapted for engagement With the standard to maintain the same in active position.

i. In a device of the class described, a bolster having intersecting vertical and horizontal slots, a standard pivoted in the Vertical slot for movement to active or inactive positions, stopplates arranged across said slot for limiting the movements of the standard, a pair of bolts for securing the plates in place and extended through the horizontal slot, and a locking member pivoted on one of said bolts within the latter slot and adapted for engagement With the standard to maintain the same in active position, the other of said bolts constituting an abutment for the locking member when swung to locking position.

In testimony that I claim the foregoing as my own I have hereto aiifixed my signature in the presence of two Witnesses.

MILES D. LIVERMAN.
