strata.

To all whom it may concern:

Be it known that l, WILLIAM T. HARDING, a citizen of the United States, residing at Raleigh, in the county of ake and State of North Carolina, have invented certain new and useful Improvements in Logging Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to logging cars and has for its object to provide a simple, comparatively inexpensive as well as a more efficient' construction for the beams and stakes and their connections, than hereto fore.

With these ends in view, the invention consists in the novel details of construction and combinations of parts all as will be more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings, forming a part of this specification, in which like numerals relate to like parts in all the views :F igure 1, is a perspective view of a car provided with my invention; Fig. 2, is an end elevational view of the cross beam and standards, illustrating the operation of the same; and, Figs. 3 and t are detail views of certain portions of the invention.

1 represents suitable cross pieces bunks or beams on which the logs rest, 2 suitable stakes or standards secured to said beams and 3 chains or other fastenings connected to said beams and stakes, as illustrated.

In designing a car for logging purposes it is very desirable, as will appear below, to put the chain 3 well up above the bunk on the back of the stake 2 and for this purpose we provide a suitable bracket 4- over which the chain loosely passes. It is also very desirable that the stake should be shouldered as at 5 and rest upon the beam 1, as shown, for when the chain is placed well up above the bunk and is permitted to extend across the angle between the stake and the bunk, the logs will rest against the chain and their weight will force the stake down- Ward against the beam thereby holding the stake in its upright position as well as giving it a downward and inward thrust. in this way the natural tendency of the logs to push the stake outward by throwing their weight against the base of the stake where it is weakest, is avoided.

Specification of Letters Patent.

Application filed March 1, 1910.

Patented Sept. 2?, 19M).

Serial No. 548,655.

ln order that the chain 3 may effectually cross the angle between the beam and stake I provide a suitable fastening 6 on the beam for one end of the chain and locate it at a suiiicient distance from the end of the beam to cause the logs to rest against the chain, and for the other end of the chain 1 provide another fastening similarly located on the other side of the beam.

It is important that the stakes should be readily detachable from the beams or bunks, and to this end I provide a latch hook 7 pivoted in the casting 8, which latch is controlled by the link 9 attached to the pullbar 10.

Since the logs rest upon the chain and strain the same considerably, it is important that this strain should be taken by the casting 8 rather than by the latch, and to this end I pivot the latch '7 so that the portion of the same between its pivot and the bend 11 takes substantially all of the strain which, of course, is transmitted to the casting S. The bolt securing this casting to the bunk may conveniently pass entirely through the same and hold or form the fastening 6 on the other side. In this way the bunk or beam is not liable to become split.

A keeper 12 is provided for the free end of the rod 10 so that there is no danger of the rod becoming detached and accidentally unlatching the chain 3.

An important feature of my invention is the structure by which I do away with all hinges betv-Jeen the bunks and stakes, as it is evident that hinges are not only expensive in this relation, but they are also very liable to become damaged and to render the use of the stakes uncertain. In my structure the stakes 2 need not be permanently connccted to the beam or bunk at all, but it is preferred to attach it by a short chain 18 in order to prevent the loss of the stake when it is not in use. T his chain 13 is preferably made only sulliciently long to lift one end of the stake free from the ground so that when the car is pushed. along the track the other end of the stake will drag on the ground and the stake will, therefore, naturally take the direction in which the car is traveling.

Another important feature of my construction is the means I have employed in ironing the bunks to prevent them from being split. To this end a pair of iron straps 15 are preferably passed along the top of each bunk and down across the ends of the same, as shown at 16, although it is not essential that the portions 15 should extend entirely across the tops of the bunks. Across the ends 16 I pass an additional strap 17 which may extend a suitable distance along each vertical side of the bunk and may be bolted thereto as by fastenings 18. The strap 1? is preferably located somewhat below the center of the beam 1 in order that the stake 2 may be readily released from the slot 30 in the end of the bunk in which its reduced end 19 fits, and to facilitate this removal the extreme end of the said stake may be beveled off as at 20. These strips 15 are secured to the bunks by the fastenings 21 and are also preferably tied together by an additional short strap 22 which crosses the bunk near the slot 30 and bends down on each side of the bunk, as shown.

It will be observed that the entire construction is exceedingly simple, strong, and capable of resisting the hard usage to which logging cars are put.

It is evident that those skilled in the art may vary the details of construction and combinations of parts without departing from the spirit of my invention and, therefore, I do not wish to be limited to such features except as may be required by the claims.

Vfhat I claim is 1. In a logging car the combination of a beam provided w'th a slot; straps passing along said beam at each side of said slot and down across the end of said beam; an additional strap crossing said first mentioned straps and said slot; a standard resting on said beam, fitting said slot and adapted to be entirely lifted therefrom, and means extending from said standard to said beam crossing the angle between the same, adapted to receive a part of the weight of the logs and to jam said standard against. said beam, substantially as described.

2. In a logging car th combination of a beam provided with a slot; a strap passing over the top of said beam and over the end of the same; an additional strap crossing said first mentioned strap and said slot; standard resting in said slot and adapted to be entirely lifted therefrom; means loosely attaching one end of said standard to said beam; and means crossing the angle between the standard and beam, adapted to receive a part of the weight of the logs carried by said car and to cause said standard to jam firmly against said beam, substantially as described.

3. In a logging car the combination of a beam provided with slots; straps passing along said beam at each side of said slots and down across the ends of said beam; ad-

ditional straps crossing said first mentioned straps and said slots below the center of said beam; standards resting on said beam, fitting said slots, adapted to be entirely lifted therefrom; chains extending from each of said standards to said beam, crossing the angle between the standards and the beam, adapted to receive a part of the weight of the logs and to jam said standards against said beam; and means for readily releasing one end of one of said chains and permitting one of said standards to fall away from said beam, substantially as described.

a. In a logging car the combination of a beam provided with a slot; straps passing over the ends of said beam at each side of said slot; additional straps crossing said first mentioned straps and slots below the center of the beam; tie pieces 22 securing said first mentioned straps together at the base of said slot; standards resting on said first mentioned straps and fitting said slots, said standards adapted to be entirely lifted from said slots; chains attaching said standards to said beam; chains 3 extending from said standard to said beam at each end, crossing the angle between the standards and the beam and adapted to receive a part of the weight of the logs and thereby jam said standards against said beam; a latch hook 7 adapted to secure the end of one of said chains 3; a link 9 adapted to hold the end of said latch; and means for readily moving said link, substantially as described.

5. In a logging car, the combination of a beam provided with a slot; straps passing along said beam at each side of said slot and down across the end of said beam; an additional strap crossing said first mentioned straps and said slot below the center of the latter; a third strap 22 to which said first mentioned straps are secured and disposed transversely of said beam at the base of said slot; a standard provided with a reduced end cut away at 20 resting on said beam and in said slot and adapted to be entirely lifted therefrom; a chain l?) loosely securing said standard to said beam; a bracket 4 carried by said standard; a chain 3- secured to one end of said beam passing over said bracket a casting 8 provided with a hook 7 secured to said beam and adapted to receive the other end of said chain 3; a link 9 secured to said beam and adapted to control the end of said hook 7 a rod 10 for operating said link and a keeper for said rod, substantially as described.

In testimony whereof, I affix my signature, in presence of two witnesses.
