3 Claims. (Cl. 304-6) .with the appended drawings, .wherein for pur-- poses of illustration I have shown preferred em bodiments of my invention.

In the drawings:

Figure 1 is a general side elevational view of the preferred form of the invention partly broken away to show structural features.

Figure 2 is an end elevational view of Figure 1.

Figure 3 is an enlarged fragmentary longitudinal sectional view taken through Figure 1 along the line 3-3 of Figure 3.

Figure 4 is a fragmentary enlarged transverse vertical sectional view taken along the line 4-4 of Figure 1.

Figure 5 is an elevational view of one of the short adjustable legs.

Figure 6 is a similar view of one of the longer adjustable legs.

the wall bracket.

middle of the horizontal brace II and its upper end secured as at I; to the other surface of the tube l adjacent its inward end.

A side of the lower end portion of each leg 1 is apertured as indicated at 14 in Figure 4 to accommodate the shank of a stop pin l which Referring in detail to the drawings, and first composed of two similar but oppositely disposed sections 6, each of which consists of a pair of vertical tubular legs 1 which are bias cut at their upper ends and secured together as by welding, as indicated by the numeral 8. The upper end of the joint thus formed is concaved and secured as by welding as indicated by the numeral 9 to the under surface of a horizontal tube Ill. As indicated in the drawings the legs 1, although located in the same plane, are slightly angulated with respectto the horizontal tube III, to which the upper ends of the legs are attached at a point inwardly of the outward ends, so that the lower ends of the legs I are approximately even with the outer end of the tube in. A smaller tubular cross brace II is secured horizontally between the lower parts of the legs I, as indicated in Figure 2 of the drawings, and a vertical tubular brace I2 has its lower end secured to the is mounted through a plate l6 secured to the outer side of the tube. The shank of the said pin is devised to enter a selected one of the transverse bores ll which are spaced longitudinally along the extensible leg l8 or i8 as the case may be, to provide the desired height for the trestle.

The short leg l8 differs from the long leg l8 only in the length. The lower ends of the legs are provided with non-skid preferably rubber material ferrules IS.

The horizontal tube i0 has a pair of vertically aligned pin receiving openings 20 adjacent its outward end and horizontal openings 2| adjacent its inward end, as well as vertically aligned openings 2| at the inner end of the tube H1. The openings 2! are threaded as indicated in Figure 3 of the drawings to accommodate a clamping screw 22 for the purpose of clamping in adjusted position in the bore of the tube H) the bar or rod 23 by which two or more of the sections 6 are assembled together to provide the desired length of trestle.

When utilizing one of the sections as in Figure 7, the same being generally designated 6a, the vertically aligned holes 20' in the inner end of the tube. I 0a are utilized to accommodate a vertical pin 24 which passes also through similarly vertically aligned openings 25 in the tubular horizontal shank 26 of the wall bracket which is generally designated 21 and which includes a wall mounting plate 28 secured to the inner end of the tubular shank 26, the said plate being provided with keyhole slots 29 to accept bolts or screws or nails for attaching the bracket to a wall or other supportingsurface as indicated in Figure 7.

Although I have shown and described herein preferred embodiments of my invention, it is to be definitely understood that I do not, wish to limit the application of my invention thereto, except as nliaiy be required by the scope of the subjoined c a ms.

Having described the invention, what is claimed as new is:

1. A trestle or the like comprising at least one section consisting of a pair of tubular upwardly converging substantially full-length legs, vertically adjustable cushion feet telescoped in the lower ends of said legs, locking means at the lower ends of said legs for holding the cushion feet in vertically adjusted position, a horizontal tubular member secured to the upper ends of the converging legs, and a horizontal support member telescoped in said horizontal tubular member,v

verging, the upper ends of the legs being chamfered and welded together, relatively short cushion feet telescoped in the lower ends of said tubular legs, locking means on said legs for looking the feet in selected vertically adjusted positions, a tubular horizontal member welded onto the upper ends of the legs, a horizontal rod telefeet.

scoped to extend from said tubular horizontal member, said rod including a wall bracket, and locking means on said tubular horizontal member for locking said rod in adjusted extension from said tubular horizontal member, said locking means consisting of a pin traversing said tubular horizontal member engaging in a selected one of a longitudinal series of holes formed in said rod.

3. A trestle comprising a section including a pair of tubular legs upwardly converging, vertically adjustable feet telescoped in the lower ends of said legs, and locking means at the lower ends of said legs for holding the feet in adjusted position, and including leaf springs secured at one end to the outsides of said legs, handle equipped pegs on the other ends of said springs, said legs having single openings therein through which said pegs extend, and said feet having series 01 openings therein for extension of said pegs therethrough selectively, said handle being retractable to draw said pegs out of said openings in the feet and thereby enable vertical adjustment of said EDWARD T, DEGLER.
