AUGUSTUS STANLEY; CFNEW BRITAIN, CONNECTICUT.

Letters Patent No. 7 7,779, dated May 12, 1868.

IMPROVEMENT IIN saw-HORSES.

l Beit known that I, AUGIUSTUVS STANLEY, of New Britairnin the county of Hartford, State of Connecticut, have invented certain new andusefldmprovements in Saw-Horses; and I do hereby declare that the following is a full andexact description thereof.

' The object of my invention is to facilitate the stowage and transportation of' these important devices, and

to Vafford a cbeap, eicienia and durable structure, which-may be folded into a small compass, and readjusted Ainto a workingecoudition rapidly, and with ,littlev labor and expense.

I'wll first describe Vwhat I consider the best means of carrying ont my invention, and will afterwards designate the pointlwhich I believe tol be new therein. The accompanyingdrawlngs form a part of this speciioation, Figure lis a side view, i

Figure 2 is an end view, and Figure?) is a top view, with.thepartsadjustedfor use. Figured is aside view,I and' Figure 5 is an end viewof my saw-buck, with the parts adjusted for packing andtransportation.

`Similar letters of reference indicate like parts in all the figures. ".lints are employed merely to aid iu distinguishing parts, and do not indicate' differences of material. The material of the whole may-bo hard wood. A' are parallel pieces, of ash or other'wood, sawn in rectangular sections. a a are connecting-braces,

which muy be introduced by screwing, or otherwise,`to hold the'parts parallel iirmly in a fixed relation to eachl i other.. Band C are corresponding. pieces, of ash or'other material, notched across with rectangularnctchs, a's

indicated by b, and c. Thesenotches .b and e extend obliquely across the inner faces of the parts B 'and C, and are of a little greater width than the parts A A above described. Their depth is suicient to let. the parts A A' into the material of the parts B and'C to a depth oi', say, about one-fourth of an inch. i

D is a well-made cylindrical brace or airis, of ash or other suitable material. It is provided with-a head, d,

which is sunlr into the part C, as represented. The shaft or body of'the brace D turns loosely inthe parts .C1 land A A, and is threaded into the part B, as represented. f I n other words, a strong aud regular screw is prei 4ducedby handor bymachiue'ry, vwhich it is .not necessary t o describe, von' the end-'of the brace D, as indicated by d', and a corresponding female screw is formed into the part B. Machinery for producing these parts'iin common use, and is well known to workers inwood. The work may be e'ected very cheaply and accurately, I

and with the consumption of very little time or'expense. v

vIn order to t my saw-horses for packing and transportation, I introduce tho screw tl but a little distance into the part B, and this allows the parts B and-C to extend at a suicient distance apart to embrace the parts AfA, and their connecting-braces a a, in the same plane, as indicated in fig. 4. This allows thsstructure to-,be

packed in a very small space. When it is desired to put the saw-horse in aconditiou for. use, it is-necessary simply to'turn the parts B'and C, so that they shallassu'nxe the proper angle with thepartsA A, and to 'grasp the brace D rmly by the middle, -by both hands, and turnit forcibly around, so as to drive the threaded part d further into the part B. This draws the parts B and C gradually together until the part-A A is'receivred.y

in the recesses or rectangular notches b c, and the whole is screwed tightly together in that'position..l The sawhorse is now ready for use, and willperform its ordinary functions in thesame manner as anvordinary saw-horse.

This condition is shown in'gure 3. i Y l It may again be put in the condition indicated gfZ and restred again inthe condition for .use as often as may be required.

It will be observed that `the locking et ,the parts A A in'the notches b c, in the .parts B and C, allows the parts to be fixed very firm and rigid, so that there is no wear-or inconvenience in the use of the s'awfhorse duo to its collapsable quality.

i Having now fully described my invention, what I claim as'new, and desire to secure byLetters Patent, is as follows:

I claim the folding parts A A', B, C, notched or recessed across, and adapted to lock into each othor,.an d be rigidly coiiued at the proper angle by the aid of the screwbrace D d d', or `its equivalent,substantially as and for the purpose herein specified. Y v
