'l-to provide easily inge support elements which cooperate with the cross piece and legs of a saw horse to firmly unite the same and yet permit a folding action of the legs so that the saw horse may be compactly folded and stored.

Another object of this invention is to provide an improved hinge support element for saw horses including a main body support plate having on opposite ends thereof upwardly struck arms for straddling and for attachment to a cross piece of a saw horse and having on opposite sides thereof depending leg portions serving to receive between opposite end portions thereof, the legs of a saw horse.

Still another object of this invention is to provide an improved hinge structure in accordance with the preceding object wherein said arms have laterally extending end portions projecting beyond one side of the main body plate and which are adapted to receive a fastening element and pivotally attach the assembly to the cross piece of a saw horse.

With the above and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended, it being understood that various changes in the form, proportions, and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is a perspective view showing a saw horse constructed in accordance with this invention and illustrating the use of the improved hinge support means therefor.

Fig. 2 is an enlarged end elevational view of the assembly shown in Fig. l and illustrating the manner in which the legs can be inwardly folded; and

end projections

27 and 28, each of which is apertured adjacent its free ends, such as indicated by the

reference characters

29 and 30, with corresponding extensions of the two legs being disposed in transversely aligned relationship and with the apertures therein also transversely aligned to receive a single fastening element, such as a bolt or the like 31, as is shown in Fig. 1, serving to pivotally attach a corresponding leg element 12 therebetween with the upper portion 32 of the leg extending into the region of the associated arm 18 and abutting thereagainst as is shown most clearly in Fig. 2.

The saw horse is assembled, as is shown in Fig. 1, with the cross piece supported on the upper portions of the plate 17 of the two

support hinge assemblies

15 and 16 and being straddled by the

upstanding arms

18 and 19 at opposite ends thereof, with the

legs

25 and 26 depending from the undersurface thereof and presenting means straddling intermediate portions of the legs 1114 and pivotally attaching them to the hinge supports and yet providing an extremely rigid assembly when set up in the position shown in Fig. 1.

When it is desired to store the saw horse, the same may be done by folding the legs 11 and 12 inwardly and then pivotally moving the entire hinge support and leg assemblies about the axis of the bolt 24 so that the same are disposed in more or less straddling relationship on opposite sides of the cross piece 10. The opposite end of the saw horse is correspondingly compacted so that the entire unit takes up very little space and may be compactly stored as desired.

I claim:

1. A hinge and support for making a carpenters saw horse, comprising a main body member having a flat, upper surface for supporting a saw horse cross piece, a pair of parallel arms extending upwardly from opposite ends of said main body member to cooperate with said main body in cradling a saw horse cross piece therein, a pair of parallel legs extending downwardly from opposite sides of said main body and each having oppositely directed, outwardly projecting extensions at its lower ends extending beyond a corresponding arm to straddle a saw horse leg, said extensions having apertures therein for pivotal attachment to a corresponding saw horse leg, and said arms being apertured for attachment to a saw horse cross piece.

2. The hinge and support as defined in claim 1 wherein said arms are provided with end extensions projecting beyond one side of said main body, the end extensions of said arms being apertured for hinged attachment to a saw horse cross piece.

3. A hinge and support for making a carpenters saw horse, comprising a unitary sheet of metallic material having a generally rectangular main body portion, a pair of upwardly struck arm members at the opposite ends of said main body portion, and a pair of downwardly struck leg members at the opposite sides of said main body portion, said arms having end extensions projecting beyond 7 one side of said main body portion and provided with aligned apertures to receive a fastening element hingedly securing the support to the cross piece of a saw horse, said leg members having laterally extending portions at their lower corners projecting outwardly beyond the corresponding arm members with corresponding extensions of the leg members being provided with transversely aligned apertures for receiving fastening elements to pivotally secure therebetween leg members of a saw horse, whereby a saw horse may be positioned between an upstanding position and a collapsed position.

4. A saw horse assembly comprising a horizontally disposed cross piece member and a pair of downwardly divergent leg members adjacent each end of said cross piece, means pivotally connecting said cross piece with each pair of legs and serving to pivotally secure said legs together, said means comprising a main body member having a fiat, upper surface upon which the undersurface of said cross piece rests, a pair of upstanding arm members rigid with opposite ends of said main body member and lying in contiguous relation along opposite side portions of said cross piece, said arm members having end extension portions projecting beyond one side of said main body member and provided with transversely aligned apertures, a fastening element projecting through said apertures and pivotally attaching said cross piece to said means, said means also including depending leg members at opposite sides thereof with each such leg member being provided with oppositely extending projections disposed at the lower corners thereof, the projections of said legs lying on the same end of said body member straddling a corresponding saw horse leg member and being provided with transversely aligned apertures receiving a fastening element pivotally attaching the saw horse leg therebetween, whereby the saw horse is positionable between an upstanding operative position and a fully collapsed stored position.
