LOGGING-CAR.

To all whom it may concern:

Be it known that I, CLINTON W. RUSSELL, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Loggingcars, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to logging cars more particularly designed for use in carrying large timber, and resides in the peculiar construction and arrangement of the bunk and the chocks, in the manner of locking said checks in relation to the bunk, and. further in the peculiar construction, arrangement and combination of parts as will be more fully hereinafter described and particularly pointed out in the claims.

In the drawings-Figure 1 is a sectional end elevation; Fig. 2 is a perspective view of one end of the bunk and chock; and Fig. 3 is an end elevation thereof.

My improved construction is aimed to increase the strength of the bunk and the convenience in arranging the adjustable chocks and their securing chain.

Another feature of my invention is the improved construction of bunk, and in this I have aimed at increased strength of the bunk and convenience in arranging the adjustable chocks and their securing chains.

Essentially my improved structure consists of a beam of H-shaped cross section L, the flanges of which are of unusual depth. The channel in the upper portion of the beam is thus of sufficient depth to receive the securing chains for the checks and to provide the necessary clearance for operating the same beneath the plane of the upper edges of the flanges.

M and N are the checks for the opposite ends of the bunk and which are adjustable into different positions. These chocks are of different construction, but both are slid ably secured within the upper channel of the beam and are supported by the web thereof. The chock M is of substantially triangular shape, having a fiat supporting base and the inclined and vertical walls M M O are apertures arranged upon opposite sides of the center and extending longitudinally through the chock beneath the plane of the upper edge of the bunk flanges.

Pare chains secured to the web portion of Specification of Letters Patent.

the bunk and some distance from the end thereof and extending through the apertures O in the chock.

Q are locking flanges for the chains upon the outer wall of the chock and which are slotted at Q, for engagement with different links to hold the chock M from further out-- ward movement.

The chains P are preferably formed as a continuous loop, having their ends secured and the looped portion extending about the outer wall of the chock M. Thus all danger of losing the chock is avoided, even in case of the accidental unlocking of the chain and disengagement from the bunk, as the loop will hold it in suspension. The chock N at the opposite end of the bunk has secured thereto the operating chain R which extends centrally along the channel in the bunk and through a central recess R in the bunk M. This chock N is normally supported in inclined position by a lug N, which rests upon the web of the bunk, but which is adapted to engage a slot S at the end of said web to permit of dropping below the plane of the upper edges of the bunk flanges. Thus without disengaging this chock from the channel it may be moved from the path of the timber during engagement or disengagement of the same from the bunk.

For locking the chain R, I have provided a simple and easily operated device, and one which cannot become detached from the bunk. This consists of a dog T in the form of a flat plate which is hinged at one end to an eye T secured to the web of the bunk L, and at its opposite end is adapted to engage a slot U in the lower flange of the bunk, being thus arranged beneath and parallel to the web of the bunk at the end thereof. For holding it in this position, a draw pin V is arranged to engage with alined apertures in ears V secured to the bunk and in the dog T. This pin in turn is secured to a chain V so as to prevent possibility of its being lost. The dog T is centrally provided with a slot T for engaging different links of the chain R, which latterdrop down through a recess R in the web of the bunk at the end thereof. Thus the chock N maybe adjusted into any desired position by drawing upon the chain R and may then be locked by engaging one of the links in the slot T of the dog T, and by engaging said dog with the slot U and looking it by the pin V. A reinforcing plate IV is preferably arranged beneath the web of the bunk and between the same and the dog T. 7

It will be observed that the chains P are arranged upon opposite sides of the channel within the bunk, and the chain It is arranged centrally therebetween. To prevent poss1- bility of fouling of these chains, or inter ference with each other, they are preferably placed in separate channels and these are formed by arranging flanges, preferably angle bars X above the web and extending longitudinally of the bunk. This will divide the space into three separate channels, the outer ones receiving the chains P and the inner channel receiving the chains R.

With the construction described in operation, before loading the car, the chock N is adjusted into position where the lug N drops into the slot S thereby permitting the body of the chock to drop into the channel below the upper edges of the flanges of the beam. Thus these flanges form an unobstructed way in which the timber can be rolled. The chock M is also adjusted before the loading of the car into the desired position, and is locked by dropping the chain into engagement with the slotted flanges Q. After loading the chock N is adjusted to the proper position and locked by engagement of the chain R with the dog T, and the securing of this dog in the slot U by engagement of the pin V with the alined apertures in the ears V and dog.

What I claim as my invention is:

1. In a logging car, a bunk formed by a beam of H-shaped cross section, a chock resting upon said beam and adjustable longitudinally thereon, and a chain for securing said chock arranged in the open channel of said beam above said web, the flanges of said beam being of sufficient depth to provide clearance for said chain in said chan nel.

2. In a logging car, a bunk comprising a beam of H-shaped cross section, a chock resting on said beam, and a pair of chains for securing said chock extending within the channel of said beam on opposite sides thereof, being secured to said beam and having a locking engagement with said chock.

3.
