THOMAS MATI-IIAS SCHMITZ, 0F CRANBROOK, BRITISH COLUMBIA, CANADA.

CAR-STAKES.

To all whomit may concern:

Be it lmown that I, THOMAS MATHIAs SCHMITZ, a subject of the King of Great Britain, residing at Oranbrook, British Columbia, Dominion of Canada,.have invented certain new and useful Improvements in Car-Stakes, of which the following is a specification.

This invention relates to improvements in looking and releasing mechanism for log car stakes and has to do with an improved construction involving? preferably a fixed and a releasable stake, and locking mechanism for holding the releasable stake in place, and adapted to be quickly and easily manipulated to release the removable stakes under the action of the weight of the logs.

The device of my invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed out in and by the appended claims.

In the drawings :-Figure 1 is a cross sectional view of the body of a flat car adapted for hauling logs and illustrating the ap plication of my invention thereto. Fig. 2 is a perspective view of a log bolster forming a part of my invention. Fig. 3 is a fragmentary view of a portion of the bolster, in side elevation, illustrating a portion of my improved locking mechanism on an enlarged scale. Fig. 4 is an edge view of the mechanism shown in Fig. 3. Fig. 5 is a perspective detail view of a releasable lock element, forming a part of my improved lock mechanism. Fig. 6 is a detail perspective view of a lock retainer, forming a part of my improved mechanism. Fig. 7 is a perspective view of an operating member for the lock mechanism. Fig. 8 is a perspective View showing an operative connection between the operating member and the lock mechanism.

Like numerals of reference designate similar parts throughout the difierent figures of the drawings.

As illustrated, the platform of a fiat car is designated as a whole at 1 and trans versely disposed thereon is a log supporting bolster indicated at 2. It will be understood that a plurality of bolsters will be provided for each car but as all of the bolsters will be of the same construction only one is herein shown. The bolster 2 is preferably provided with concave or hollowed out end portions 3 and 4, and in order to protect the Specification of Letters Patent.

margins thereof I preferably secure metal facing plates 5 and 6 to the sides thereof as shown. It will be understood that each bolster will be provided with a pair of

stakes

7 and 8, and for convenience in designating one from the other, I will hereinafter refer to the stake 7, as the fixed stake, and the stake 8, as the releasable or removable stake.

These car stakes are usually cylindrical in form and'are designed to fit the hollowed ends 3 and 4 of the bolster, as indicated in Fig. 1. A strap or yoke 9 is secured to the bolster 1 so as to embrace the fixed stake 7 and hold the same'in position against the end of the bolster and against the side of the platform 1 of the car. As a further means of securing the fixed stake 7 to the bolster 2, I provide a link chain 10 which encircles the stake 7, preferably at a point above the bolster 2, and passes through an opening 11 in the bolster. A snatch hook or other suitable take up device may be provided for tightening the chain 10 but as this form of device is common in the art the same is not herein illustrated.

At the upper end of the stake 7 a clevis 12 is attached and the same is connected chain 13 and a retaining chain 1 1-. The retaining chain 14 is somewhat longer than the releasable chain 13. Throughout the specification in referring to the connecting elements as chains, it will be understood that any other equivalent connecting means may be used, within the scope of my invention.

The releasable chain 13 is connected with an eye member 15 having a straight portion 16 adapted to be loosely disposed in an open slot 17 in the releasable stake 8. The retain ing stake chain 14 is provided with a hook and eye permanent connection with the stake 8 which is indicated at 18 and 19.

The

stakes

7 and 8 are shown in the position which they would occupy when the car is loaded with logs and the releasable chain 13 under this condition, would be taut and would serve to hold the upper ends of the

stakes

7 and 8 in a vertical position. When the lower end 8 of the releasable stake is released then the longer chain 14 will prevent the stake 8 from falling down on the ground. The lower end of the stake 8 is held 1n posiend of which may be the rear side of the opposite to the side remaining end of the adjustably secured to bolster 2, or that side shown in Fig. 2. The

chain 20 is secured to an eye 21 of a releasable locking element 22. This element 22 may be in the form of a flat strip of metal, and as shown, the same is provided with upper and lower male looking

portions

23 and 24. Said element tapers from its rear end toward its eye end and the tapered edge portions are indicated at 25 and 26. A fixed locking portion is rigidly secured to the facing plate 6 and is indicated at 27. Said fixed locking portion 27 is provided with a female locking notch 28, adapted to receive the male looking portion 23, and an inclined edge 29 adapted to engage the tapered edge 25 of the element 22.

A pivoted or movably mounted lock retainer is indicated at 30 and is pivoted to the plates 6 and 31. Said retainer 30 is provided with a female or notched receiving portion 32 for receiving the male looking portion 24. The edge 33 of the retainer 30 engages the edge 26 of the element 22. The retainer 30 is provided with a notched or recessed portion 34 adapted to receive the upper end 35 of a trip 36 which is pivotally mounted to the plate 6 at 37. A bar 38 pivoted at 37 and 39, extends across the element 22 and serves to hold the same in coincident relation with the fixed locking portion 27 and the retainer 30. A lug 40 secured to the fixed lock portion 27 and a lug 41 secured to the retainer 30, both overhang the locking element 22 and serve to hold the same in the planes of the

parts

30 and 27.

The locking mechanism shown in Fig. 3 is in a position to lock the chain 20 and hold the stake 8 in the position shown in Fig. 1. It will be seen that the line of pull of the chain 20 is angular to the longitudinal axis a a of the element 22, and therefor the strain is not wholly imposed upon the locking

portions

23 and 24 but is also exerted laterally with respect to the length of the element 22 and such lateral stress or strain is taken up by the

edges

29 and 33 of the

parts

27 and 30. l/Vhen the lower end of the trip 36 is moved to the left of Fig. 3, then the retainer 30 is released and is free to drop downwardly whereupon the outward pressure of the logs exerted on the stake 8 will cause the same to move outwardly and the chain 20 will carry with it the releasable locking element 22.

An operating member is provided for the locking mechanism which may comprise a rotatable or rocking pipe 42 adapted to be disposed longitudinally of the car and to be received in recesses 43 of the bolsters. The walls of the recesses 43 embrace the pipe 42 so as to permit the same to be oscillated or rocked to and fro but held to a fixed axis of oscillation. The operating member 42 is provided with arms 44 adapted for connection with links 45 one being shown pivotally connected with the lower end of the trip 36. A bolt 46 is connected with the arm 44 and has a threaded end adapted to engage the upturned portion 47 of the link 45. A cotter pin orlike means 48 may be employed to secure the bolt 46 to the arm 44. The threaded end of the bolt 46 provides for adjustment, initially, and also in case of wear of the parts. Means is provided for holding the operating member 42 against movement when the locking mechanism is in .a locked position, and such means may comprise a hook 49 pivoted to the bolster 2 and provided with a'hooked end adapted to enter an opening 50 in the member 42. When the member 42 is released, the same may be rotated by inserting a rod or like implement through holes 51.

Assuming that the parts are in the position shown in Fig. 1, and that it is desired to unload the car, the operator will first dis connect the hook 49 from the member 42 and then rotate the member 42 to the left of Fig. 1 whereupon the trip 36 will release the retainer 30 thereb releasing the element 22, as hereinbefo-re described.

When first adjusting the stake 8, before the car is loaded, it may be necessary to employ a short chain 52, connected at its ends to the bolster as shown in Fig. 1, until outward pressure of the loaded logs is exerted upon the stake 8 to tight-en the chain 20. It is not'contemplated that the chain 52 will remain on the car but will be detached from the loaded cars and reused in loading other cars.

WVhile I have herein shown and described one specific embodiment of my invention it is to be understood that I do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. In combination, a flat car, a log bolster thereon, a fixed stake secured to one end of said bolster, a rotatable lock operating member loosely disposed on said car and held to a fixed line of rotation by said bolster, means for locking said member to said bolster against rotation, locking mechanism on said bolster, a releasable stake, a chain connecting said releasable stake with said locking mechanism, and meansoperatively connecting said locking mechanism with said operating member, substantially as de scribed.
