To all whom it may concern:

Be it known that I, CLARENCE A. HEssER, a citizen of the United States, residing at Newbern, in the county of Craven and State of North Carolina, have invented certain new and useful Improvements in Logging Cars, of which the following is a specification.

This invention relates to attachments for railroad cars and more particularly to an attachment for a logging car.

The primary object of the invention is to provide a device for engaging and holding the standards which retain the logs on the car in a manner that will permit the standards to be released whereby the logs may be permitted to roll off without danger to the workmen engaged in the unloading operation.

The invention has for another object to provide a locking mechanism mounted on each of the logging car bolsters and so associated with a chain and a retaining plate as to permit the standards to be held against accidental displacement until such time as the locking mechanism is released.

Another object of the invention is to provide a device of this character that may be released from a point at the side of the car, opposite to that from which the logs are to be ejected, the unloading operation being accomplished with a minimum of exertion by the workmen and with the least possible danger of injury.

A further object of this invention is the provision of a logging car which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following descrip tion and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a fragmentary side elevation showing the device attached to a car bolster and engaged with an upright standard, part of the device being broken away to dispose the operating mechanism.

Fig. 2 is a top plan view of the device.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line H of Fig. 1. Fig.

F 6 is a detail fragmentary elevation of a portion of the device. v

Referrlng to the drawings wherein is illustrated the preferred form of my invention and in which like characters of reference indicate corresponding parts throughout the several views, the car platform A is supported on the usual stringers B. Upon the platform of logging cars of this character is generally mounted a plurality of bolsters one of which is indicated at C. These bolsters are employed to mount the logs upon the car when the logs are in transit. For the purpose of retaining the logs in position when they are piled upon the bolsters, it is necessary to provide standards equally spaced along each side of the car and one of these standards is indicated at D.

As shown in Figs. 1 and 2 of the drawing, the bolster C is provided at one end with a pair of spacing blocks 1 and 2 to which is attached a plate 3 so that the plate is spaced away from the side of the bolster to form a pocket 4 open at its end. Received in this 5 is a section on the line 55 of pocket is a tongue 5 which has a notch 6 formed in its upper edge. One end of the tongue has a finger 7 which projects forwardly from the pocket 4: and is looped to receive an eye 8 attached to a retaining plate 9. This retaining plate is connected to a link pivotally mounted on the opposite side of the bolster C and it will be obvious that when the tongue 5 is released from the pocket 4 the plate 9 will be permitted to swing outwardly to disengage the stand-. ard D.

Pivotally mounted in the pocket 4, on a pivot pin 10 journaled in the bolster, is a latch lever 11 having a bit 12 adapted to register with the notch 6 when the opposite end of thelatch lever is raised as shown by full lines in Fig. 1 of the drawing. This end of the latch lever 11 projects rearwardly into a space 12 formed between a plate 13 and the side of the bolster C, the plate being mounted upon and fixed to a spacing block 14 and depending therefrom to the surface of the platform A. This structure is clearly shown in Fig. 4 of the drawing. A complementary latch lever 14 also has one of its ends projecting into the space 12 and its opposite end pivotally supported by pivot pin 15 journaled in the bolster C. This end of the latch lever 14 is protected by pocket 16 formed by plate 17 mounted upon two of a size to fit snugly in the space between the lever 14 and the proximate edge of the spacing blocks 18. The key 21 is connected by a link 22 to a chain 23 which is extended forwardly and upwardly at an angle and embraces the standard D at a point above the plate 9 from which point it extends around the standard and is connected to a. cleat 24 mounted on the opposite side of the bolster.

As will be apparent from the full lines in Fig. 1, the overlapping ends of the levers 11 and 14, within the space 12, are held in operative position by a sliding supporting bolt 25,. This bolt extends through the bolster C from the side opposite to the levers and projects into the space 12 and through a convenient opening in the plate 13. The opposite end of the bolt is pivotally connected to the arm 26 of an operating crank which includes the elongated bar 27 rotatably supported in the bearings 28. This bar extends along the side of the bolster C to the opposite end thereof where it is provided with a depending handle 29 held in inoperative position by pivoted clip 30 which, as shown in Fig. 6, may be swung upwardly to released position.

It will be understood that a series of these devices may be mounted upon certain of the car bolsters to retain the standards D in position for preventing displacement of a load of logs. \Vhen in operative position the parts are in position as shown by full lines in Fig. 1 in the drawing. To release the standard in order that the logs may be permitted to roll from the car, it is merely necessary to swing the clip 30 to the position shown by dotted lines in Fig. 6 and pull outwardly on the handle 29 thus swinging the arm 26 to withdraw the latch levers 11 and 14. The lever will then immediately swing down into position as shown by dotted lines in Fig. 1 and, by virtue of this movement, the tongue 5 and the key 21 will be permitted to move out of this position in its corresponding pocket. Since this operation is accomplished from the side of the car opposite to that from which the logs are to be unloaded, it will be apparent that no danger'to the workmen will be in evidence.

It is also to be noted that the device may be used equally as well upon logging trucks and sleighs such as are used in logging camps in conveying the logs from the source of supply to the railroad.

From the foregoing it will be observed that a very simple and durable logging car has been provided, the details of which embody the preferred form. Idesire it to be understood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.
