Application October '7, 1937, Serial No. 167,854 1 Claim. (01. 304-5) This invention relates to a table, bench or trestle and more particularly to a sawhorse used in connection therewith, the sawhorse being‘espe cially useful for picnic tables, benches and tres 5 tles such as are used in the home, at churches, lodges, banquet halls, as well as by carpenters, ‘paper hangers, painters and other workmen. The invention aims to provide an exceedingly simple novel construction which may be manu factured at low cost in any size, in mass produc tion, the same comprising three parts demount ably connected together. The more speci?c objects and advantages will become apparent from a consideration of the de scription following taken in connection with ac companying drawing illustrating an operative embodiment. ‘ In said drawing: Figure 1 is a View showing the invention in 2O . side elevation; Figure 2 is an end elevation of the invention; Figure 3 is a vertical sectional view taken on the line 3—3 of Figure 1; and Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure 1. Referring speci?cally to the drawing, wherein like reference characters designate like or similar parts which may be manufactured in any desired size and of any preferred material, 10 designates a top bar, usually of wood, which has its edge horizontal. spreading means are provided as at l8. Such means may consist of links H], pivoted by rivets 20 to the legs and by a rivet 2| to each other, their movement to spreading position being lim— ited by a hook 22 on one of them engaging a link ‘adjacent to the same. By such a device, any suitable degree of pressure may be applied ac 10 cording to the proportioning of the parts. In addition, to provide an exceedingly rigid structure, braces 23 are pivoted at 24 to the legs and they have hook ends or slots 25 which re leasably engage headed lugs 26 carried by the top bar 10. As a result of the construction described, three separable devices constitute the invention namely the top bar II] and supporting devices I l, and al— though detachable and separable from each 20 other, when assembled, provide an exceedingly rigid structure and the support of the top bar ID occurs at the metal plates or cleats I6, avoid— ing splitting of the legs at the notches I3. The structure is exceedingly simple, handy and ef? 25 cient in the home, factory, an auditorium and various places. Various changes may be resorted to provided they fall within the spirit and scope of the in30 vention. I claim as my invention:- , Associated with the top bar and detachable therefrom and from each other are supporting devices ll, one at each end thereof. The legs of each device H are adapted to clampingly grip the top bar [0 in the slots or grooves l4 and to this end, suitable toggle or Said de A structure of the class described having a top bar, supporting devices therefor, said devices comprising legs, spreading means connected to a; vices II have legs l2 usually of wood which. are ‘ the legs, said legs being notched at one end to 35 engage the top bar, cleats pivoted to the legs notched at l3 so as to extend into grooves or slots [4 in opposite sides of the top bar In, which grooves are lined with felt, rubber or any soft or cushioning material as at 15, to enable the legs to engage in the slots or grooves with vary~ ing pressure. Difliculty is experienced with the legs unduly wearing, breaking and splitting at the cutaway portions or notches l3, and to this end, plates or cleats l6 are provided on opposite 45 sides of the legs, for direct engagement by the lower edge of the top bar l0. Such plates or cleats are riveted as at H to the legs. adjacent the bases of the notches at points out wardly of the notches and arranged to directly support said top bar to minimize danger of split ting of the legs, compressible material lining the 40 grooves, and the spreading means for the legs comprising links pivoted to the legs and to each other, one of the links having a hook thereon en gageable with the other link to limit their relative movement. - MARCUS WESTWANG.
