TRESTLE.

SPECIFICATION forming part of Letters Patent No. 704,687, dated July 15, 1902. Application filed lPebruary 14, 1902. Serial No. 94,044. (No model.)

To all whom it may concern:

Be it known that I, l/VILLIAMA. KIBBE, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in Trestles; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to trestles, and particularly to knockdown or folding trestles adapted for the use of paper-hangers, painters, &c.

The objects of the invention are to form a trestle easy to set up and take down and foldable into a compact form. The parts of the trestle are permanently connected together, so that the liability of accidental separation or loss of any of the parts is prevented. The trestle can be folded into an unusually compact form without the removal of any bolts or other detachable parts.

Further objects and advantages will appear from the following description, in connection with the accompanying drawings, in which- Figure 1 is a front elevation of the trestle. Fig. 2 is an end elevation thereof. Fig. 3 is an edge view of the trestle folded. Fig. 4 is an end view of the same.

Referring specifically to the drawings, 6 is the beam, which sustains whatever is placed on the trestle. The pairs of spreading legs are indicated at 7 and 7, and the members of each pair are connected together at the head by crossed links 8, pivoted thereto. These links are preferably fiat thin metal plates, and their upper edges enter notches 9 in the lower edge of the beam. The heads of the legs are beveled on their inner faces, as at 10, forming jaws to clamp the beam when the legs are spread. The legs are retained in spread position by spacing-rods 11,

which are pivoted at one end to one leg and have the other end formed into a hook 11, which enters a hole 12 in the opposite leg.

Braces 13 are pivoted to the inside of each leg and extend thence to a common pivot 14, by which they are connected to the beam, two on each side thereof.' These braces are preferably formed of thin fiat metal plates adapted to lie between the beam and thelegs when the trestle is folded.

One end of the beam is short, as indicated at 6, and to fold the trestle the legs are placed in parallelism with the beam in the following manner: The spacing-rods 11 being un hooked, the legs 7 are brought toward each other to release the beam from the jaws, and then the heads are swung out until the links will pass the end of the beam, when the said legs can then be brought up and around until they'lie by the upper edge of the beam, one leg on each side. The legs 7 after releasing the beams from the jaws in a similar manner are then turned on the pivots of the braces 13 until they lie along beside the lower edge of the beam, one on each side. The legs are preferably half the width of the beam, so that when folded a rectangular bundle is formed. The links are of sufficient lengthto permit a suitable spread to the legs, and this length will be found when the parts are in the folded position to be quite proper to accommodate the beam and the braces between the legs without allowing any objectionable play. WVhen the trestle is set up, it is rigid, strong, and Well braced. The links engage the notch in the beam and take the weight of the latter, so it cannot slip.

WVhat I claim is 1. A folding trestle comprising a beam, spreading legs having jaws at the upper ends thereof to clamp the beam ,and pivotedcrossed links connected to said legs and taking the weight of the beam.

2. A folding trestle comprising spreading legs having jaws at the upper ends thereof, a beam clampedin said jaws and having anotch in the lower edge thereof, and pivoted links connected to said legs and engaging in said notch.

3. Afolding trestle comprising a beam, two pairs of spreading legs the upper ends of which have connecting-links and jaws to clamp the beam, and braces pivotally connected to the legs and opposite sides of the beam, said beam having a short end which will pass within the A k 704,687 i connecting-links of one pair of legs, whereby to opposite sides of the beam, so as to lie be said pair may be folded around along the uptween the beam and the legs when folded. 10 per edge of the beam. In testimony whereof I aflix my signature 4. A folding trestle comprising a beam, in presence of two witnesses. spreading legs having pivoted connecting- WILLIAM A. KIBBE. links and jaws to clamp the beam, said legs Witnesses: I and beam being foldable to parallelism, and JOHN H. WHITSON, braces pivoted to the inside of the legs and J. HARVEY LUCE.
