KENNETH Ross, or Bormi'in, MONTANA.

STAKE-POCKET.

To all whom t may concern.'

Be it known that l, KENNETH Ross, a citizen of the TJnited States, residing at Bonner, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Stakedgockets, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in stakepockets; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

The present improvement is directed to car-stake pockets, the main object sought being to provide a pocket which will eectively hold the stakes in an upright position and thus prevent the load from spreading at the top, such spreading as is well known, interfering with the movement of the load through tunnels and Howe trussbridges. A further object is to entirely relieve the bunks or cross members supporting the load from any longitudinal strain by the elimination of any positive connection between the pocket and the end of the bunk. In the present embodiment of my invention special provision is made for permanently maintaining the axis of the pocket in a vertical plane so that the stake will remain in the same plane while in service. rl`he present stake-pocket and the means by which the same is secured to the side of the car present mechanical advantages over prevailing forms of stakepcckets and stake-holders, these advantages being fully apparent from the following detailed description of the invention in connection with the accompanying drawings, in whichrFigure lrepresents a side elevation of the platform of a freight car such as used for transporting logs showing my invention ap plied thereto; Fig. 2 is a vertical crosssection on the line 2-2 of Fig. 1; Fig. Sis a top plan of the stake-pocket; Fig. 4 is a side elevation thereof with side sill ofthe car in cross-section; Fig. 5 is a front elevation of the pocket, parts being removed; Fig. 6 is a vertical cross-section on the line G-G of Fig. 3, showing in addition the end of the bunk in side elevation; Fig. 7 is a vertical cross-sectional detail on the line 7-7 of Fig. 6; Fig. 8 is an enlarged side elevational detail o f the locking latch and tripper with part of poelfet 'wall in section; Fig. 9

aside elevation of the locking latch; Fig. is an inner edge view of the same; Fig. 11 is a side elevation of the tripper for the latchgand Fig. 12 isV an inner edge view thereof.

Referring to the drawing, 1, represents the side sill of the platform or frame of a car, said sill in the present embodiment of my invention being a structural member in the form of a flanged plate or channel beam, although I do not wish to be understood as limiting myself to any particular cross section of side sill or the material of which the same is constructed or composed. Bolted to the side sill 1 is the pocket-body or casting 2 on the outer face of which is formed the substantially semi-cylindrical pocket formation or depression Z having the bottom sloping bounding edges c, e, as shown. Theupper jortions of the side edges of said depression are recessed-to a suitable depth leaving shoulders s for the support of the terminals of the substantially semi-cylindrical cap-piece 3 operating as a complementary member to the pocket-body, and forming with the concave walls of the depression Z an opening or passage-way O whose walls entirely surround the stake S inserted thereinto. Onone side, the cap 3 is provided with a centrally disposed perforated ear or lug Ll tol which is coupled one endY of a link 5, the opposite end of the link being connected to a U-bolt 6 whose arms are passed through openings o, o, in the adiacent side of the pocket-body 2 (Fig. 5), the nuts n securing said bolt to the body. On the opposite side, the cap 8 is provided with a centrally disposed lug` or ear 4 having an elongated slot h which is freely tiraversableV by U-shaped clevis 7 the free ends of whose arms are connected by a pin 8 to which is pivotally secured between said arms one end of alatch or hook 9 operating freely in the vertically elongated slot or opening of the pocketbody or plate 2. The free end of the latch is provided with a locking head m which, when the latch is in its depressed or locking position engages the plate 2 below the bottom of the slot t, said plate serving as a keeper for the latch (Fig. 8). The latch may be disengaged from Vthe plate 2 by means of a tripper 10 Vpivoted at one end to a headed stud or pin 11 on the adj acent side wall of a rear cavity or receptacle 12 by which the end of the cross timber or car bunk 13 is received. The tripper 1G in shape resembles a bell-crank lever, oscillating about the aXis of the stud 11, one arm of the bell-crank being in the form of a {inger a above which is formed a cavity c (Fig. 11) which receives the free end of the latch, the finger being in permanent engagement with the locking head m of the latch. To the eye c of the other lever arm may be attached a cord or chain (not shown) for operating the tripper. When the latter is oscillated to the dotted position indicated in Fig. 8, the latch will be raised to its unlocked or released position, and may be withdrawnrfrom the slot t by moving the clevis 7 outwardly along the slot 7L of the lug or ear Ll. In this manner one side or end of the cap 3 may be readily uncoupled from the body 2 and swung outwardly (about the U-bolt 6 as an axis) whenever occasion arises to remove a stake (dotted position Fig. 3). l/Vhen the latch 9 is down, the tripper 10 serves the purpose of a lock, preventing accidental displacement or movement of the latch which cannot be raised without an upward oscillation of the finger a )ecause conlined by the walls of the cavity c, (Fig. 8).

As was pointed out above, the pocket-body is secured to the side sills 1 of the car. In the present embodiment of my invention the body or plate 2 is bolted to the side sill, the plate being provided with bolt holes o to receive the bolts 14, and with holes o to receive the threaded ends of the arms of the U-bolt or strap 15 which passes around the lower terminal of the stake. The upper portion of the pocket-body (opposite the bottom of the cavity 12) is provided with openings z'. i, for receiving the terminals of the cross tie-rods 16, by which the members of each pair of pocket bodies disposed opposite one another on the sides of the car are tied together. It is to be understood of course that for every pocket-body on one side of the car there is a corresponding pocket-body on the opposite side, the two being tied together by the tension members or rods 16. The tie rods are disposed in pairs, with one rod 'on each side of a bunk 13, the terminals of the bunks being received in the cavities or pockets 12 of the oppositely placed pocket-bodies 2. a bunk being thus confined between two tie-rods (Fig. 3). The pocket formations or cavities 12 rest directly on the upper flanges of the sills 1, the tie-rods 16 connecting opposite pocket-bodies being raised slightly above the side sills or platform of which they form a part, and serving not only as ties between opposing pocket-bodies`r but means for relieving the strain on the car sills. Thus the cross rods 16 serve the double function of keeping the pockets in place and of tying the sills. rlhe sides and bottom oic the terminals of the bunks received by the cavities or bunkspockets 12 are recessed or rabbeted so as to be snugly received by the cavity, the bottom recess being of a depth to bring the lower face or" the bunk in the plane of the bottom face of the cavity (Fig. 6). The walls of the cavities 12 are suliiciently deep t0 protect the ends of the bunk dropped thereinto, and when the bunks are once in place .in thecavities they require no bolting, since, under my improvement the bunks are not required to take care of any portion of the strain imposed by the load on the stakes S and pocket-bodies 2.

IVithout the complementary member 3 the depression or semicylindrical formation Z can scarcely be considered as a pocket; and it may accordingly be assumed that said complementary member enters into the construction of the stake-pocket proper. In

lthe present embodiment of my invention the passage O formed by the inner walls oi the member 3' and of the depression ,CZ is cylindrical, that is to say circular in cross-section; but I desire it to be understood that I need not adhere to this particular cross-section and any other form of cross-section, such as elliptical, polygonal and the like comes within the scope of my invention. Ot course the holder or support for the stake S is not complete without the U-bolt 15; and while this bolt is not strictly a. part of the pocket it cooperates with the pocket proper so as to rigidly hold the bottom of the stake against movement, the nuts n on the screw-threaded terminals of the bolt arms making it possible to adjust the available opening through the bolt so as to grip the stake with any degree of firmness desired. The stake-pocket proper may be said to be without a bottom, or to have an open bottom, such open bottom allowing the stake to be driven into the pocket to firmly hug the pocket walls, and

the walls of the loop formed by the U-bolt. Especially is the open pocket desirable in cases where the stakes become seasoned and loose in the pockets while in use. rIhe open bottoms of the pockets permit the loosened stakes to be driven and wedged in more deeply into the pockets, thereby giving eX- cellent service. In addition the adjustable U-bolt 15 may be positioned to grip the lower end of the stake with any degree of firmness. In practice of course it is to be understood that before a stake is driven into its pocket, the member 3 is first swung to closed position and locked by the latch 9 to the plate 2 (as a keeper), the tripper 10 being oscillated to lock the latch against disengagement from said plate as previously described. The U-bolt 15 may be set to proper position to grip the stake while the latter is being driven intoits pocket, or be passed about and caused to grip the lower end of the stake after the stake has been fully inserted into the pocket.

For convenience, we may consider the cavity or receptacle 12 which receives the end of the car bunk 13 as a pocket; so that it would follow that the casting or pocket-body 2 is provided with two pockets, one for receiving a stake, and the other for receiving the end of the bunk, the pockets being on opposite sides of the casting and opposite one another. As previously pointed out, the present construction prevents the load irom spreading at the top by maintaining the stakes permanently in an upright position or in truly vertical planes. This is made possible by the tie rods 16, their position being such as to effectively resist the outward thrust of the load against the stakes. Under this thrust the plates 2 would naturally tend to oscillate awayfrom the sills 1 about fulcrums located in the region of the U-bolts 15; but the tie-rods 16 are positioned high enough (being above the sills 1) to take up and resist this thrust and thereby maintain the plates and the axes of the stake-pockets in vertical planes, the plates being held in permanent rigid connection with the sills 1 to which the outward thrust aforesaid is communicated, no part of this strain or thrust being however com- A municated to the bunks 13 which support the logs or load. The axes of the stakepockets being thus maintained in vertical planes it follows that the stakes driven into them will remain in an upright position thereby preventing the load from spreading at the top. The construction here shown need not of course be adhered to and changes within the purview of the skilled mechanic might be resorted to without departing from the nature or spirit of the invention. Features shown but not specifically alluded to are well understood in the art and require no description in the present connection.
