The present invention is directed to improvements in saw horses.

The primary object of the invention is to provide a device of this character which can be easily and quickly folded in order that it can be conveniently transported or stored.

Another object of the invention is to provide a device of this character which is so constructed that it can be conveniently folded 10 or unfolded and when unfolded Will be rigidly maintained.

Another object of the invention is to provide a device of this character which is simple in construction, durable, efiicient in operation 15 and one which can be manufactured at a minimum cost.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the device in its operative position.

Figure 2 is a longitudinal sectional view through the same.

Figure 3 is a longitudinal sectional view showing the horse folded.

Figure 4 is a bottom plan View showing the horse folded.

Figure 5 is a sectional view on the line 55 of Figure 2.

Referring to the drawings, the numeral 1 designates the main beam,'to the sides of which are suitably secured the side boards 2, said beam having its under surface provided with spaced recesses 3, the purpose of which will be later explained. Supported by the side boards 2 are bolts 4 to which are pivotally connected blocks 5, said blocks having longitudinal slots 6 formed therein which are bridged by pins 7, and pivotally connected to said pins are the outer ends of the arcuate arms 8, said arms having seats 9 formed near their free ends which are adapted to engage with the cross rods 10 supported by the side boards 2.

Pivotally connected to each block 5 is a pair of legs 11, said legs being connected by brace bars 12, one of said bars having a stop 1 3'cariied thereby itd 'coat'with the companion bar to pesitio-ni f 1 I 7 Each block 'efhasfsecured thereto a cross strip 14, strips being provided with rebent "ends 1 to provide stops 15 which are adaptedto engage the'legs when th'eks'ameare ihfth ""uiifoldedposition.- The strips l' are inset-lie the blocksb to'a'dmit of the legs 11 lying clo e against the outer sides of said blocks; j i a gslfi are? provided andhave their hold said barsin their operative fflheafs-prin W p out (ls-fixed in the recesses8, said springs beingad p'tied to engage the arms 8 and will obv'io'uslyj-serve to hold the seats '9 firmly engagedwith-"the ro'ddlO-[Whnthe horse is inf-its'operative position or as more clearly shown'in 'Fi gure 2 of the --drawings.

From the foregoing, it seamenane many advantages of the herein Ldescril)ed=invention' will be apparent to those skilled in the art without further de scription, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What is claimed is:

1. A device of the class described comprising a beam, side boards carried by the beam, blocks pivotally supported between the side boards and having legs pivotally connected is thought i that the x ion thereto, arcuate arms'having one of their ends pivotally connected to the blocks and having seats in their outer ends, rods supported by the side boards, said arms being movable over the rods, and springs carried by the beam for forcing the arms in a direction to draw the seats to engage said rods to hold the blocks against accidental movement. 7 y p 2. A device of the class described com- 10 prising a beam, blocks pivotally connected with the beam, legs pivotally connected with the blocks, arcuate arms carried by the blocks,

ps carried by the blocks for limiting the a swinging movement of the legs, and yieldable means carried by the beam for engaging the arms to hold the blocks against pivotal movement.

3. A device of the character specified comprising a beam, blocks pivoted to the beam,

a pair of legs pivoted to each of theblocks to swing. laterally, meansfor limiting the lateral spread of the legs, arms pivoted to the blocks, and means on the-beam adapted to coact with the arms to hold the legs in upright position. a T

4:. A device of the character specified comprising a beam, blocks pivoted to the beam, a pair of legs pivoted to each of the blocks to swing laterally, cross strips on the blocks having opposite end portions rebent to provide I stops to engage the legs, brace bars connecting the legs of each pair, arms pivoted at one end to the blocks, and means on the beam adapted to coact with the arms to hold the legs in upright position.

5. A device of the character set forth comprising a beam, boards at the sides of the beam, blocks pivoted at one end to the side boards to fold therebetween, a pair of legs pivoted to each of the blocks to swing lateral- 1y, brace bars connecting the legsto limit their lateral spread, cross strips on the blocks having their ends rebent to engage the legs, curved arms ivoted at one end to the blocks and notched adjacent their free ends cross rods supported in the side boards and spaced from the beam to receive the pivoted arms, and flat springs secured to the and exerting a pressure on the pivoted arms to hold them in engagement with the said cross rods.

In testimony whereof I aflix my signature.
