l.. v. CLINE FOLDABLE AND ADJUSTABLE sAwHonsE Filed May 16. 1929 .E mw e m A TTORNEY Patented Jan. 19, 1932 PATENT OFFICE LUTHER CLINE, OF SAN DIEGO, CALIFORNIA FOLDABLE AND ADJUSTABLE SAWI-IORSE Application mea May 16, 1929. serial No. 363,446.

My invention relates to saw horses, more particularly to foldable and adjustable saw horses, and the objects of -my invention are: first, to provide a saw horse in which the legs thereof fold together and against the back of the saw horse, thereby forming a compact bundle suitable for easy transporta tion; second,.to provide a saw horse which is rigid and sturdy of construction when .in its open position; third, to provide a saw horse in wliichtlie wood portions thereof protect the tools ofva user from Contact with the metal portions of the saw horse; fourth, to providea saw horse the height of which may be readily varied; fifth, to provide a saw horse which is adjustable so as torest solidly although the surface upon which it rests is uneven; sixth, to provide a means in connection with a saw horse of this class which positively holds the legs thereof in various shifted positions, but which may be readily released when desired; seventh, to provide a novelhinge mechanism especially adapted for a saw horse of this class, and eighth, to provide a saw horse which is extremely simple of construction proportional to its functions, durable, ecient in its action and which will not readily deteriorate or get out of order.

lith these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will behereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part V of this application, in which:

Fig. 1 is a fragmentary side elevational view of my saw horse; Fig. 2 is a fragmentary end elevational view thereof; Fig. Seis an enlarged fragmentary sectional view thereof through 3 3, of Fig. 2; Fig. 4 is an enlarged illustration; Fig. 7 is a substantially diagrammatical view of the sawhorse in its folded position.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

.Back member l, shielding plate 2, leg inembers 8, hinge leaves 4, hinge body 5, leg hinge leaves 6, brackets 7, pin members 8, brace. members 9, washers 10, springs ll, securing means l2 and catches 13, constitute the principal parts and portions of my saw horse.

The back member l is formed of a piece of Wood having a substantially rectangular cross-section and suitable length. Its upper surface is protected by a shielding plate 2, also of wood, which issecured thereto `by screws 2a. These screws are countersunk as far as possible into the shielding plate, so that the tools of the carpenter Will not come in contact therewith.

Four leg members 3 are provided, one pairnear each end of the back member l. Hinge leaves 4 are secured to the underside of back member l near each end thereof. A hinge body 5 is secured to each hinge leaf at the side of said hinge leaf facing the corresponding end of the back member. A leg hinge leaf 6 is adapted to be pivotally secured to the hinge body 5 along each side thereof, as shown best in Figs. 3 and 4. The hinge leaves 6 pivot about an axis which is at right angles to the pivotal axis of the hinge body 5. Each hinge leaf 6 is secured to the upper inner side of one of the legmembers 3. It is preferred to have the plane common to each pair of legs 3 intersect the back member 1 at an angle a few degrees off the perpendicular therelwith,so that the extended ends of the pair of legs are further yapart from each other than their secured ends, thereby bracing the backA member l against end movement.` The eX- tended end of each hinge body 5 which ter minates substantially flush with the outer iside of its corresponding leg members, is providedwith a depending integral bracket 7. Each bracket is provided with a slot 7a eX- tending longitudinally therewith adapted t0 receive a pin member 8.

Pivotally secured in superposed relation on the pin member 8 against the rear side of the bracket 7 are the one ends of a pair of braces. Each brace member 9 extends downwardly and outwardly and is pivotally secured by means of a screw 9a or the like to the outer side of one of the leg members as shown best in Fig. 2. The pin 8 extends inwardly from the brace members 9 between the corresponding pair of legs 3 and terminates in a head portion 8a, as shown best in Fig. 3. Between the head 8a and the inner brace 9 are two washers 10 which are resiliently held apart by a spring 11. The other end of the pin 8 extends into the slot 7a and is screwably mounted in a securing means 12.

The securing means 12 is provided with two lugs 12a on its face which rides against the outer side of the bracket 7. These lugs 12a are adapted to engage any oppositely disposed pair of a plurality of holes 7?) formed in the bracket 7 along opposite sides of the slota, as shown best in Fig. 5. The securing means 12 is also provided with a ring 12b adapted to be engaged by a finger. The spring` 11 tends to hold the lugs 12a in interlocking relation with the holes 7b. An outward pull on the ring 12b disenga-ges the lugs 12a from the holes 7b and permits the shifting of the securing means l-ongitudinally with the bracket, thereby bringing the legs 3 nearer together or moving them further apart, depending upon which direction the securing means is shifted.

A cut-out portion 1a is provided in each end at the under side ot the back member 1. Each cut-out portion la is adapted to receive a catch member 13. The catch member is confined within the cut-'out portion 1a except for a catch portion 13a thereof which is adapted to project through a slot a formed near the extended end of the hinge body and engage the one margin. The catch portion 13a is adapted to firmly hold the hinge body against the under side of the back member 1. A handle portion 13b of the catch member 13 extends towards the corresponding end of the back member 1 past the margin of the corresponding bracket member 7, where it may be readily engaged b y pressing upwardly into the outer end of the cut-out portion 1a. The handle portion is normally held downwardly by means of a spring shown by dotted lines in Fig. 3y of the drawings. Although the catch is housed by the back member 1, so that the saw or other tools of the user will not come in contact with it, it is readily accessible.

The saw horse is folded by shitting the securing means 12 towards the back 1, thereby bringing the extended ends of the corresponding pair of legs against each other, then releasing the catches 13 and pivoting the hinge bodies with the legs 3 about the axes of said hinge bodies with the hinge leaves t- This brings the legs to the position as shown in the diagrammatical View Fig. 7. llhe members of one pair of legs are brought against each other, while the members of the other pair of legs are brought against the outside of the first pair. The positions of the holes 7b and the brackets 7 may be so arranged that when the legs are in the position shown in Fig. 7, the lugs of each securing member register with the holes 7 b so as to lock the legs in this position and enable the saw horse to be transported without danger of thelegs shifting to an extended position.

As indicated in Figs. 1 and 2, and by the dotted line in 7, the pair of legs which, when folded, constitute the outer pair, may be provided with pegs. These pegs fit into corresponding sockets on the outer sides of the other pair of legs. thereby enabling the securing means 12 to hold the leg members S5 3 in fixed folded position.

Although I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular con. 90 struction, combination and arrangement oit parts and portions, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
