SPECIFICATION forming part of Letters Patent No. 748,698, dated January 5, 1904.

Application filed January 19, 1903. Serial No. 139,496. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM MARTIN CAIN, acitizen of the United States, residing at Carlton, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Position-Governing Means for Load-Retaining Stakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to position-governing means for load-retaining stakes for vehicles and other load-bearing structures, and particularly for platform and logging cars, and has for its object the provision of simple, cheap, and effective means for securing a loosely-attached side stake in a vertical position, which means may be easily operated from a position of safety to release said stake from such vertical position.

It consists, in combination with a vehicle or other load-bearing structure, of a looselyattached side stake for supporting the load,

an anchorage secured tosaid structure at one side of said stake, flexible means secured to said anchorage and adapted to pass outwardly partly around said stake, a guide-bracket se cured to said structure at the opposite of said stake and adapted to deflect said flexible means from a horizontal to a vertical course, means secured to said structure at the last said side of said stake for temporarily securing the free end of said flexible means, and means for operating said securing means.

It also consists of certain other construc tions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a portion of the longitudinal sill and platform of a platform-car, showing my invention in operative position attached thereto. Fig. 2 is an end elevation of the same. Fig. 3 is a detail in vertical transverse section of the temporary securing means for the free end of said flexible means. Fig. 4 is a top plan View, on a reduced scale, of a portion of a modified form of my said invention, showing the same attached to the transverse bolster of a logging-car. Fig. 5 is an end view of said bolster on a reduced scale, showing a modified form of said temporary securing means attached thereto.

In the drawings, 1 is the sill of a car, to which is attached a vertically arranged bracket 1, having forwardly-directed checks 2, between which cheeks, near the lower end of said bracket, is hinged an upwardly-directed tongue 3 of any suitable construction.

'A stake 4 is, in operative position, vertically supported in said bracket and preferably rests upon the hinge of said tongue and is retained in said position by said cheeks and said tongue. Said stake is further retained in vertical position by a chain 5, or other suitable flexible means, secured at one end to any suitable permanent anchorage,which anchorage is secured to said structure and preferably consists of a sliding eyebolt 6, projected through a second eyebolt or bearing 7, secured to the platform 8 of said structure and adapted to be retracted by means of a terminal not 9 operating against the face of said bearing 7. Said chain is adapted to pass outwardly partly around said stake and the upper end of said tongue and downwardly through an eye formed in the outwardly-projecting end of a guide-bracket 10, secured to said platform or sill. The free end of said chain is secured to a pin 11, approximately similar in construction and adapted to be engaged by approximately the same means as that heretofore described and claimed by me in my application for patent for securing and releasing means for load-binding chains, filed in the United States Patent Office on or about the 20th day of October, 1902, and numbered serially 127,907. Said pin construction and means for securing the same briefly consist of said pin 11, formed with a hook or eye at its upper, end to engage said chain and having a transversely directed semicylindrical slot 12 formed in its shank portion, adapted to engage a rod 13, projected horizontally through a housing or housings 14, secured to said sill by any suitable means, which rod is slotted through a portion of its diameter between. the walls of said housing,

as at 13, whereby said rod is adapted in one rotatedposition to permit the lower end of said pin to pass across it, and in another rotated position to engage said slot in said rod, means for rotating said rod and controlling sell type.

the same consisting, preferably, of a pipe 15, secured to one end of said rod and extending to the end of the load-bearing structure, an operating-lever 16, pivotally secured to the free end of said pipe, and a bracket 17, secured to the end of said structure and having upper and lower lips extending therefrom adapted to receive the free end of said operating-lever, and a pin 18, adapted to be projected downwardly through apertures formed in said lips forwardly of said operating-lever to retain said lever in locked position between said lips. Said bolt 6 may be positioned, if desired, above the platform of said structure by simply reversing the direction of said bolt 7; but I prefer to place it below said platform, as shown, and in such case the attached end of said chain is carried down through an aperture formed in the said platform behind said sill, which aperture may, if desired, be lined with metal in any suitable manner.

When it is desired to attach said invention to the end of a transverse sill of a loggingcar, the details of construction may without departing from the spirit or scope of my said invention be modified or altered in any suitable manner--as shown, for example, in Figs. 4 and 5 of said drawings, in which 19 represents a portion of said bolster, to which said bracket 1 is attached by means of a bracket 20 of modified box-shape construction, secured to the back of said bracket 1 and directed toward and adapted to receive the end of said bolster. To one of the side walls of said box-shaped bracket, near the upper edge of said bolster, is secured a'guide-eye 21 and below said eye is secured to said side wall the -upper end of said housing 13, the lower end of which housing is preferably in such case modified by the formation of an angular extension adapted to project under said bolster to take part of the upward strain of said chain 5. To the opposite side wall of said box-shaped bracket is secured a guideeye 22, and an eyebolt 23 is projected through said side walls and bolster in such manner that the eye portion registers with said eye 22. The side wall is preferably turned outwardly, as at 24, behind the eye of said bolt 23 to form an additional bearing for the bolt 6, which is projected rearwardly through the eye of the bolt 23 and through a registering aperture formed in the said outwardly-bent end of said side wall. The upper lip or wall 25 of said box-shaped bracket projects over the end of said bolster and is preferably secured to a transverse strap 26, extending longitudinally of said bolster and secured thereto and usually forming part of the construction of the well-known logging-car of the Rus- Said stake is, further, preferably secured by a chain 27 or other flexible means, extending from the top of one stake 'across the load to the top of the opposite stake, for which purpose I preferably comically reduce the top of said stake and. form a vertical recess therein. A strap 28, apertured at its center and near both ends, is bent over the top of said stake in such manner that the central aperture of said strap registers with the vertical aperturein said stake. The forward and rearward faces of said stake, near the top thereof, are vertically channeled to receive the thickness of said strap. One end of said chain is then dropped into said vertical aperture and a bolt is passed through the lower ends of said strap and through said post and through the lower end of said chain within said stake. Half-rings 29 are then adjusted around said stake over the ends of said strap, and a bolt 30 is passed through the said half-rings and stake at right angles to the first said bolt, which strap and rings and bolts prevent splintering or splitting of said stake. The free end of said chain is provided with a hook adapt-ed to engage a link of a chain 31, directed toward it from the opposite stake, said chains being preferably joined at about the center of the load and above the same, a few logs being loaded above said chain to take up the slack therein.

While I have described certain embodiments of my said invention, it is obvious that it may within its scope be modified or altered in certain details to adapt it for use on constructions of various types or as may seem otherwise advisable, while retaining its general features and mechanical characteristics, and I do not, therefore, desire to be limited to the exact details of construction shown.

In operation said stake is erected upon said bracket 1*, and said tongue is raised into position against it. Said chain is then passed outwardly around said stake and the upper end of said tongue and downwardly through the eye of said bracket 10, and the terminal pin 11 is projected downwardly into said housing 14 and across said rod 13 through said slot 13*. The rod is then rotated until it engages the slot 12 in said pin. The operating means is then looked in position, as aforesaid, and the load is thereupon embarked. To release said stake from a vertical position, said operating-lever is first released and said rod 13 is rotated until it clears the slot in said pin 11, whereupon the pressure of the load against said stake causes the same to force said tongue outwardly, and thereby draws said pin from said housing 14 and said chain from the eye of said bracket 10, whereupon said stake is released and falls from said bracket 1 thereby releasing the load.

Having now described my invention, what I claim, and desire to secure by Letters Pat-- cut, is--- v 1. In position-governing means for load-retaining stakes, the combination with a loadbearingstructure provided with a stake-supporting bracket, of flexible means secured at one end to a permanent anchorage upon said structure, at one side of said stake, and adapted to extend outwardly partly around said stake, a locking-pin carried by the free end of said flexible means, means for temporarily engaging said locking-pin to secure said flexible means in operative position, means for operating and controlling said temporary engaging means, and means for directing the course of said flexible means, substantially as described.
