ADJUSTABLE STAND.

Application filed. November To (ZZZ whom it may concern Be it known that I, THOMAS H. BHEDMON, a citizen of the United States residing at llleadville, in the county of Crawford and State of Pennsylvania, have invented new and useful Improvements in Adjustable Stands, of which the following is a specification.

This invention is designed for use in repairing motors, particularly automobile mo-- tors. It is desirable to have the motor supported in such a manner that it may be swung in different positions to provide for convenience of operation and conditions of light. It is also desirable to have the support so formed that it may be adjusted to different motors.

The invention is illustrated in the accompanying drawings as follows Figure 1 shows a plan view of the stand.

Fig. 2 an end elevation. Fig. 3 a side elevation of the base.

Fig- 4: a part of the swinging support.

Fig. 5 a side elevation of the upper end of the frame.

1 marks the base. This is formed of longitudinally arranged angle irons. A wheel 2 is journaled on each rounded end of a squared rod 2 at one end of the base and supporting lugs 3 project from the opposite end of the angle iron base 1. By this construction it is possible to move the stand in different positions relieving the weight somewhat from the lugs and yet the lugs supply suiilcient resistance to retain the frame in' the position where it is desired to operate.

The frame has the upright standards 4c which are formed preferably of angle irons with a U-bend, one leg being preferaliily vertical and the other slightly at an angle so as to more thoroughly brace the upright. A cross beam 5 ext-ends from one leg across the frame and a cross beam 6 from the other leg across the frame the lower angle iron of the cross beams 5 and 6 affording a securing means to the base 1. The cross beams 5 and 6 are secured to the legs of the upright or standard by means of bolts 7 and with the base by means of bolts 7. A brace 8 is secured to the beam 5 by means of bolts 8 and has the upwardly extending ends which are secured to the leg of the brace 8 by means of bolts 8. A similar brace 9 is secured to the cross beam 6 by means of bolts 9 and with the upright by means of bolts 9*. It will be seen, therefore, that the frame Specification of Letters Patent.

formed with the base and upright standards is very rigid and yet the space between the standards is open or unobstructed so as to permit of the movement of the swinging support within the space.

The upper face 10 of the standard 4: forms a support for a bearing for the swinging support. This bearing is in the form of a clamp having a base 11, a bend 12 and a projection 13. A bolt 1 1- extends through the part of the standard 10, the plate 11, projection 13 into an elongated nut 15. A handle 16 extends through the nut 15 by means of which the bearing may be contracted or expanded as desired. The plate 11 is preferably permanently secured to the upper part 10 of the standard by means of bolts 11.

Trunnio-ns 17 are arranged in the clamping bearings and extend from the sides 18 of a swinging support. These sides are in the form of angle irons and are connected with the cross beam 19 by means of the corner irons 20. The corner irons are connected with the sine beams 18 and cross beam 19 by means of bolts 21. A series of holes 22 are arranged in the side beams by means of. which the endwise position of the cross beam 19 may be adjusted by changing the bolts 21 and the cross beam 19 has a series of openings 23 by means of which the distance between the side beams may be adjusted and the cross beam secured by means of the bolts 21. The height of the cross beam relatively to the side beams may also be adjusted by utilizing the openings 20 in the corner irons. In this instance again the bolt 21 is removed and the cross beam adjusted to the point desired.

It will be noted that the trunnions when the clamps are loosened not only permit of the swinging of the support but permit of the adjustment of the side beams in and out to any width desired. This gives a very much more rigid support than where the entire frame is adjusted in width.

\Vhat I claim as new is:

1. In an adjustable stand the combination of a frame comprising side standards; a swinging work support; trunnions extending from the support; and clamp bearings for the trunnions permitting rotary and axial movement of the trunnions when released whereby the support may be tilted and adjusted in width.

2. In an adjustable stand, the combination of a frame comprising standards; a

7 tion of a frame comprising side standards;

a swinging work support comprising side beams and a cross beam; corner plate connecting said beams, said connections being adjustable; trunnions extending from the .side beams; and clamp bearings for the trunnions' permitting rotary and axial movement or the trunnions when released whereby the support may be tilted and adjusted in Width.

4:. In an adjustable stand, the combination of a base; standards extending uprightly from the base; cross beams connectingthe standards adjacent to the base; braces between the cross beams and the standards; a swinging support; clamp bearings on the standards; trunnions on the swinging support extending into the clamp bearings; and means for adjusting the Width of the support, said adjustment involving axial movement of a trunnion in a bearing.

In testimony whereof I have hereunto set my hand.
