T0 LZZ whom t may concern:

Be it known that I, ALEXANDER R. ME- BANE, acitizen ofthe United States, -residing at Hickory Flat, in the county of Benton and State yof Mississippi, have invented new and useful Improvements in Car-Standards, of which the following is a specication.

This invention relates to what I shall for convenience term car-standards or, as sometimes known, car-stakes.

The invention also relates to means for mounting kthese standards in place and for holding Ythem in operative relation and in such manner that they may be swung down into line with a car or at right angles thereto. The means for holding the standards or stakes vertical secure them solidly in such relation,

so that the load will .be held against lateral shifting movement. A car equipped with my .invention is .adapted particularly for carrying lumber or logs, although it may be uti-lized for carrying loads of yother .material which 4have in themselves .a tendency to shift sidewise. These :standards .are generally arranged in pairsfand I mayequip a car with any number of cooperating pairs of standards, this 4being a matter of detail, for the inventiondoesnot concern this point nor the vparticular mounting and relation of the parts.

The .standards of each pair are connected by tie-bars, and these are vertically adjustable. The tie-bars serve to aid in preventing spreading of the standards or stakes, and they lie ontop-of the load to prevent upward movement thereof, means of a suitable nature being provided to prevent accidental upward displacement of these tie-bars.

In the drawings accompanying and Aforming a -partof'this speciiication I show a sim- .ple form of embodiment of the vinvention `which to enable those skilled .in the art to practice the same I will set forth fully in the following description, while the novelty of the invention will be included in the claims succeeding said description.

In the drawings, Figure 1 is an elevation of a standard involving my invention. Fig. 2 is a side view of the same. Fig. 3 is atop-plan view of a portion of a cross-bar.- Fig. 4 is a detail in perspective of a locking-pawl.

Like characters'refer to like parts throughout the several views.

In the drawings the numeral 2 denotes the body of a flat'or equivalent car upon which lumber or any other material may be laid.

From what :has been hereinbefore .stated it will be evident that I may employ any number ofstandardsina-ssociationwithsaidcar-body. These standards, as indicated, are generally arranged in cooperating pairs, one standard of each pair being designated by v3 and the opposite standard being designated yby 4. I give the standards distinguishing characters, for the reason that one of them, .at its upper end, is a little different in construction than the other. Across the car extend rod means', as 5, which may, vif desired, consist, as illustrated, of a single rod, said rod when employed extending entirely across the oar through and beyond the side sills thereof. This rod means need not necessarily consist of a continuous part, for it may be divided and in such event would consist of .bolts .extending through the side sills.

. It will be obvious that I .use .the .designation H.rod means ina broad .sense Vto include a .continuous rod or a divided rod, which would be .composed of two bolts or sections. The opposite `ends of the rod are shown .as threaded to receive the Vnuts 6, and .between the nuts 6 and the outer faces-of the-sidesills of the car arelocated blocks, eachdesignated by 7, the rod extending through these blocks and serving as a pivot therefor. The standards 3 and 4 .are pivotally supported by the blocks .7, the pivots for the standards being designatedby 8 and extending longitudinally of the car. The pivots 8 permit -the .standards 3 and 4 to be swungdownward fromxa vertical to a horizontal positionat right .angles tto the car, .and vice versa. In vlie'w .of the fact that the standards `rare carried'bythe blocks 7 it will be evidentthat said standards can be brought along the `oppositesides `of the car to extend longitudinally thereof. At the opposite sides ofthe car are plates 9, located above the respective pivots 8, said plates having notches into which the standards 3 and 4 can set when said standards are vertical or upright to aid in maintaining such relation. Instead of forming .notches lin plates, as 9, the notches may be .formed directly in the car. Each standard when swung down horizontally to extend lengthwise of the car is supported by a pair of brackets,l each designated by 10, and one of which may be equipped with a latch, .as 11, .to -prevent IIO associated with a car that whentheyarezdown and extend longitudinally of the car they point away from opposite ends thereof, by virtue of which when they are in such relation they do not project beyond the opposite ends of said car. Each standard is shown as carrying near its cooperating supporting-block a detent or latch, as 12, and the detents may be pivoted to the standards. These detents or latches 12 when in operative positions engage against the upper sides of the respective blocks 7 and abut against shoulders, as 13, on said blocks, such abutment preventing j the outward swinging of the standards.

Whenthe latches or detents 12 are manipulated to carry them clear of the shoulders 13, the standards can be swung outward and downward to occupy horizontal positions. The standards fit, of course, in slots 1n the two blocks, and their butts are squared off, so as to fit solidly against the bottoms of said slots when the standards are in an upright position.

In connection with each pair of standards I provide a cross-bar or strap extending from one standard to the other standard. The stra shown extending between the two standar s is designated by 14. It may, if desired, consist of a continuous member or may consist of a plurality of hingedly-connected members, such point being immaterial. The standards extend vertically through the cross-bar or strap, the latter having a vertical movement with respect to the standards and being ada ted to overlie the load and to be fastened firm y against such load. The standards are shown as notched or toothed, as at 15, on their outer edges, the notches extending from near the latches 12 to the heads of said standards. The purpose of these notches will hereinafter appear. One of the standards, or that designated by 4, is shown as having an offset head 16, provided at its outer end with a nut 17, said nut preventing the accidental separation of the strap or cross-bar 14 from said standard. By removing the nut, however, the two parts can be easily separated. They are normally together, and when there is noload on the car the cross-bar or strap 14 can be laid against the standard 4 and the two parts laid in the brackets or recesses 10. The strap or cross-bar 14 is re resented as provided at its opposite ends an outside the two standards 3 and 4 with pawls 18 and 19. I give these pawls distinguishing characters, for the reason that one of them is slightly dierent in construction to the other. The working or free ends of the pawls engage in the notches or teeth 15 of the two standards,

so as to prevent accidental upward displacement of the cross-bar by the load. By disengaging the pawls from the notches or teeth 15 the cross-bar or strap can be readily elevated, and when it is in an adjusted position said pawls will be put into engagement with the said teeth.

In some cases the load on a car is apt to shift, and in this event ordinarily some trouble will be experienced in disconnecting the strap' 14. To permit the unloading of said car, I provide a strap of such construction that no matter to what extent the load may shift or settle theseparation of the strap can be quickly and easily effected, said strap for this purpose having in the present case a detachable connection with one of the standards, such as the standard 3. Said strap 14 has a side opening 20a to receive the standard 3, the two parts being fastened together by a latch, as 21, pivotally mounted on the said cross-bar or strap 14 adjacent the standard 3 and adapted to extend across said opening and to engage a keeper or catch, as 22, suitably fastenedto the said cross-bar or strap.

It will be assumed that said latch 21 is in its working relation, its free portion at such time being under the keeper 22. To disconnect the strap 14 from the standard 3, the latch 21 will be disconnected from the keeper 22 and lifted, so as to uncover the opening 20, whereby the said strap 14 can be separated laterally from the standard 3. The presence of this latch and its keeper 22 affects in no wise the vertical adjustment of the strap. For additional security in holding the latch 21l in engagement with its keeper 22 I may provide the pawl 19 with a projection 23 to engage against the side of the latch 21 when the latter is in its operative position to positively maintain such relation'. f

When the standards 3 and 4 are in their upright positions and tied together by the cross-bar or strap 14, they are prevented positively and effectually from spreading. When the cross-bar is fastened in an adjusted position, it 'cannot be accidentally elevated, as the locking- pawls 18 and 19 will prevent the same. It is a simple and ready operation to disconnect the strap or cross-bar 14 from the standard 3, so that `the standards can be swung down to effect the unloading of the car.

9. The combination of a pair of opposite standards, one of which has an oiset head provided with a nut, a strap connecting the standards, said nut serving to prevent accidental separation of the strap from said standard with said oiiset head, and means carried by the strap to prevent accidental upward movement thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
