Application March 20, 1933, Serial No. 661,679 2 Claims. (Cl. 3046) My invention provides an improved device of are preferably square steel rods that fit into the the type generally designated as a sawhorse, but angles of the respective legs 13. At their lower which is capable of a wide range of use and is ends, the flanges of legs 13 are provided with inespecially adapted for use to support the boards turned lips or portions 16 that loosely embrace of a scaffold or the like. and hold the leg extensions for sliding movements {in Generally stated, the invention consists of the only. novel devices, and combinations of devices here- The extreme lower ends of the leg extensions inaiter described and defined in the claims. 15 are turned outward to afford feet 17 that may,

adapts the device for use to support scaifolding in proper position for a workman, having respect to the height of the ceiling or other structure that is being worked upon. The knock-down or foldup feature adapts the sawhorse to be stored in sinall space and to be easily carried or shipped from place to place.

In actual practice, the device has been found to be highly efiicient for the various purposes had in view, and can be made at comparatively small cost and is very strong and durable.

What I claim is:

1. A sawhorse comprising a top rail, hinge brackets secured to the bottoms of said rail, said brackets at their outer ends having spaced hinge lugs and at their inner ends having bearing sleeves, legs pivoted to the lugs of said brackets and diverging downwardly therefrom, tie plates rigidly connecting said legs in pairs and having spaced ears, and bail-like oblique braces pivotally mounted in the bearing sleeves of said brackets
