5 Claims. (01. 304-5) My invention relates to carpenters horses, Sheet metal, nly Portions of Which are fl ed, and more particularly a carpenters horse that is as will be explained in connection with the demade up of metal frame members and lumber scrip of Said frame membersordinarily found on a building job. Said frame members have leg portions 5 which 5 It is a purpose of my invention to provide a are channel-shaped in cross section, having the 5 carpenters horse that is made up of a pair of outwardly directed flanges 6 thereon. Said leg duplicate frame members, that is simple and portions diverge from each other transversely cheap in construction, and which at the same of the horse and are inclined at an an e to the time will make a strong and rigid horse wh n transverse connecting portion 1, so that the leg 10 the frame members are assembled with pieces of portions of the two frames extend away from 10 lumber ordinarily plentiful ona building job. eac Ot er he ass mbled n t e horse, as

If the legs 5 and for providing a longitudinal member below the ransverse po t s 1 are made piece O top member thereof, which serves as a shelf channel iron, the flanges 6 of the channel are for tools and other equipment, and also acts as bent outwardly so as to extend the same in the means for bracing the horse. a same plane as the web portion of the channel, to

Other objects and advantages of my invention The transverse portion 1 is thus considerably will appear as the description of the drawing wider than the leg portions 5, providing a smooth proceeds. I desire to have it understood, howflat face for engagement of the member 9, made ever, that I do not intend to limit myself to the of wood, which is secured thereto, to form the top 49 particular details shown or described, except aspart of the horse, by means of the countersunk 0 defined in the claims. headed securing elements H), such as bolts, which In the drawing: extend through openings bored in the piece of Fig. 1 is a longitudinal vertical sectional view lumber 9 and through openings ll provided in through my improved carpenters horse, taken the fiat transverse top portionv l of each frame.

The angle member I2 is provided with depending ear portions H, which are formed by cutting off the flange l3 from the angle member l2 at the ends thereof and bending down the ears I! at an oblique angle, said ears ll being, of course, extended in a plane that is both oblique to the flange l3 and the bottom flange of the angle member 12, to thus cause said ears 5'! to lie flatwise against the obliquely inclined inner faces of the web portions of the channel shaped legs 5. Said ears I! are secured rigidly in fixed position on the inner faces ofthe-leg portions 5, by riveting, or welding, or in any other manner, rivets IB'being illustrated as being provided for this purpose. Openings 59 are also provided in the legs 5 above the angle members 2, so that bracing members 20 can be pivoted to the leg portions 5, by means of bolts 2|, should this be desired or found necessary, said bracing members being provided with eyes 22 for pivotally mounting the'same on the bolts 2|, and being provided with eyes 23 that lie in a plane transverse to that of the eyes 22 for securement flatwise to the under side of the top forming member 9, by means of bolts 2d, which are countersunk, as will be evident, one bolt 24 being provided for each pair of members 20, the same inclining toward the center line of the horse, as will be evident from Fig. 2.

It will be obvious that the frame members, instead of being made out of structural shapes and cut and bent into such shape as shown in the drawing, can be made of sheet metal, cut and flanged as shown, provided a sufficiently heavy gauge of sheet metal is used to obtain the desired strength andrigidity for the frame members.

What I claim is:

1. In a device of the character described, a rigid, integral frame member comprising a flat transverse top portion and legs channel-shaped in cross section integral with said top portion diverging from each other downwardly from said top portion and extending obliquely to a transverse plane perpendicular to said top portion, and a bracing member angular in cross section extending between said legs in spaced relation 1 to said top portion, said bracing member having a horizontal leg and an upwardly directed flange and having depending integral ears extending at an oblique angle to said horizontal leg and rigidly secured to said diverging legs.

2. In a device of the character described, a rigid frame member comprising a flat transverse top portion and legs channel-shaped in cross section integral with said top portion diverging from each other downwardly from said top portion, said frame members being bent on divergent lines at the junction of said top portion and said legs so that said legs extend at an oblique angle to a transverse plane perpendicular to said top portion, the flanges on said leg portions being directed outwardly, and a bracing member angular in cross section connecting said legs in spaced relation to said top portion, said bracing member having an upwardly directed flange and having downwardly obliquely extending integral ears secured to the flat inner faces of said legs.

3. In a device of the character described, a rigid frame member comprising a flat transverse top portion and legs channel-shaped in cross section integral with said top portion, said legs diverging from each other downwardly from said top portion and also both extending obliquely relative to said top portion in the same direction to bias said top portion relative to said legs, a bracing member angular in cross section connecting said legs in spaced relation to said top portion, said bracing member having an upwardly directed flange and having obliquely extending integral ears secured to said legs, and a second set of bracing members each pivotally mounted on the inner faces of one of said'leg portions and converging from said pivotal mounting.

4. A carpenters horse comprising a pair of metallic frame members, each comprising a fiat transverse top portion and legs channel-shaped. in cross section integral with said top portion diverging from each other downwardly from said top portion, said top portion and said leg portions being joined on lines oblique to each other, a longitudinal top member overlying and bolted on said top portions of said frames face to face so that said legs diverge downwardly both lengthwise and crosswise of said horse, each frame having a bracing member angular in cross section connecting said legs in spaced relation to said top portion, said bracing member havin an upwardly directed flange and having obliquely ex tending integral ears secured to said legs, and a longitudinal bracing member forming a shelf secured to said angular bracing members with the ends thereof in engagement with said upstanding flanges thereof.

5. A carpenters horse comprising a pair-of metallic frame members, each comprising a fiat transverse top portion and legs channel shaped in cross section integralwith said top portion diverging from each other downwardly from said top portion and extending obliquely to the central plane of said top portion, the flanges on said leg portions being directed outwardly, a longi tudinal top member overlying and bolted on said top portions of said frames with said legs diverging downwardly both lengthwise and crosswise of said horse, each frame having a bracing member angular in cross section connecting said legs in spaced relation to said top portion, said bracing member having an upwardly directed flange and having downwardly obliquely extending integral ears secured to the inner faces of said legs, a longitudinal bracing member forming a shelf secured to said angular bracing members with the ends thereof in engagement with said upstanding flanges thereof, the pair of said pivoted bracing members mounted on each frame converging upwardly and being secured to said top member centrally thereof.
