W AGQjN-STAN DARu smmembt forihing part at Letters Patent No. 735,356, ted August 4, 1903. Application filed E'ebrnary 10, 1902. Serial No. 933386. (No model-l To all whom it may concern.-

E Be it known that 1, WILLIAM J. DONNELL, a citizen of the United States, residing at South Amboy, in the county of Middlesex and State of New York, have invented a new and useful Wagon-Standard, of which the following is a specification.

My invention is an improved wagon-standard having a verticallyadjustable slide by means of which the height ofth'e standard may be varied as may be required by the height of the load or box.

One object of my invention is to effect improvements in the construction of the standard and slide by means of which the inner side of the latter is within the plane of the inner side of the standard.

vide the slide with a cap, which when the slide is lowered in the standardcovers the top of the latter and protects the same and prevents water or dirt from working between the slide and the slot in the standard in which the slide isc'ontained.

WVith these and other objects in viewmy invention consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed. 7 h

In the accompanying drawings, Figure 1 is a perspective view of a wagon-standard constructed in accordance with my invention,

showing the same attached to a bolster, Fig. 2 is a detail perspective view of the slide, showing the same detached from the standard. Fig.3 is a cross-sectional view taken on a plane disclosing the set-screw.

In theembodiment of my invention I provide the standard 1, which is preferably made of steel or iron, with a slot 2, which extends from the lower end of the standard to the upper end thereof and which slot is open on the A further object of my invention is to proinner side of the standard, as at 3. The said slot is T- shaped or laterally shouldered in cross-section, as at 4, and the said lateral shoulders thereof are here shownas angular in form, but thefsame may he of any other suitable form, and I do not, therefore, limit myself in this particular. The standard is provided at its lower end, at its front and rear sides, with depending flanges 5, which project beyond the inner and outer sides of the standards, as at 6, being sufficiently widened to form the shoulders 7, and the said flanges bear against the front and rear sides of the bolster a and are secured thereto by screws, bolts, or other suitable devices, (indicated at b.) The lower end of the standard proper bears squarely on the top of the bolster and A further object of my invention is to proslot the said slide isfitted and is adapted to be moved. The shoulders 9 of the slide engage the shoulders l of the slot or groove and retain the slide against appreciable lateral movement in said slot or groove, and the inner side of the said slide is within the plane of the inner side of the' standard, and is hence kept out of contact with the side of the wagon .box or bed or of the load, so that the slide may be readily adjustedand is prevented from becomming jammed in the standard,

and yet the inner side of the slide, when the latter is raised, will bear against the top box and sustain the latter against the stress to which it is subj ectedwhen thewagon isloaded. It will be readily understood that if the slot -01 groove in which the slide is vertically movable is made in the nature of a socket a portion of the metal will be interposedbetween the slide and the side of the wagon-box, and a space thus created which would cause the side-boards or eXtension-boardsof the wagonbox to tilt outwardly when the slides should be raised for the purpose of admitting such side or extension boards. By the construction herein described the slide 8 may be almost in contact with the outside of the wagon-box;

and yet sufficient play left to insure absolute freedom of movement.

It will be understood that my improved standard is equally well adapted for use when the bed or box is taken off the running-gear, and the load, as lumber, poles, or the like, is placed directly on the bolsters between the standards.

At the-upper end of the slide 8 is a cap 10. The sides of the same project laterally beyond the sides of the slide, and the size and shape of the cap correspond to the upper end of the standard, so that when the slide is lowered to, its full extent in the standard the cap entirely covers the upper end of the latter and excludes dust and rain from the groove or slot in which the slide is placed. The cap has its outer side provided with a thumb-piece or handle 11 to facilitate the adjustment of the slide. handle is downturned to be out of the way when the cap is used as a fulcrum piece in loading and unloading the wagon. The cap also prevents grit, pieces of bark, chips, and the like from getting between the slide and the standard when the wagon is being used for hauling poles, logs, or lumber.

In one of the sides of the standard, perpendicular to the wagon-box, is a threaded opening 12, which is near the top of the standard. A set-screw 13, which is here shown as provided with a winged head to enable it to be readily turned by the thumb and forefinger, operates in the threaded opening 12 and may be engaged with one side of the slide to lock the latter at any desired adjustment. By thus disposing thesetscrew, which is the securing device of the adjustable slide, in one side of the standard which is perpendicular to the side of the box the said set-screw is out of the way, forms no obstruction to the loading or unloading of the wagon, and is not likely to be broken by contact with the load.

The outer end of the thumb-piece or An opening may be made in the bolster and the slide lengthened, so that its lower portion will pass through said opening when the slide is lowered to bring the cap on the upper end of the standard.

Changes may be made in the form and dimensions of the various parts and other modifications may be made within the scope of my invention. I 1

Having thus described my invention, I claim 1. A wagon standard having a vertical laterally-shouldered groove or slot, T- shaped in cross-section, in combination with a vertically adjustable laterally shouldered slide, T- shaped in cross-section, movable vertically in said groove and having its inner side within the plane of the inner side of the standard.

2. A wagon-standard having a verticallyextending groove, T- shaped in cross-section and provided at its lower end with shouldered side plates engaging recesses in the sides of a wagon-bolster, in combination with a vertically-movable slide, T-shaped in crosssection, provided at its upper end with a cap having an outwardly and downwardly extending thumb-piece adapted to serve as a
