Application tiled November 25,1913. Serial No. 802,935.-

To all whom it may concern,

Be it known that I, MAX Fnrs'r, a citizen of the United States, residing at Toutle, in the county of Cowlitz and State of Washington, have invented certain new andV useful improvements in Footboards, of which the following is a specification.

My invention pertains to improvements in foot boards, and has for its object to pro- 1@ vide a foot board for wood choppers which may be easily manipulated to secure it in a notch of a tree, where itwill, when released by the workman, automatically engage and retain its hold in the tree.

A further object is to provide in a device of the character indicated, a simple and efficient implement which possesses much utility and economy of construction.

I attain the objects indicated by means of the structure illustrated in the accompanying drawing, in which Figure 1 is a plan view of my improved board. Fig. 2 is a front end view of same. Fig. 3 is aside elevation showing the device engaged in the notch of a tree, as in use.

Referring to the numerals in the drawing, 1 represents a main plate formed preferably of casting, upon the front end of which is formed an off-set portion which depends to rest upon the lower side of the notch 13, when in use. rlhe lower face of said of-set portion is cut away at 9' leaving each lateral edge 10 reduced to a more or less sharp edge coextensive with its longitudinal dimension, which is adapted to cut into the woodupon which it rests to prevent lateral movement of the plate. The casting is reduced from the upper face of the offset portion at 11 for the purpose of retu ducing the weight and material to the desired amount; and for the further purpose of giving an upward inclination thereof at the terminal portion. The edge portions of the lower face are rounded from' the rear t5 to the' front end of the upper face, thus forming with the latter a sharpened terminal portion 2 which will engage in the upper face 12 of the notch under force of the weight of the instrument and workman standing thereon. The intermediate portion of the edge 2 may be cut away at 2 to facilitate the engagement of the remaining prongs 2 in the wood. Centrally in the late 1 is formed the countersunk aperture g to receive the headed bolt 14 which passes through the board 3 pivotally supporting it thereon.

rlhe rear end of the rplate 1 is rounded on the arc of a. circle whose center is at the bolt 7. Parallel to the rear edge of the plate 1,

a short distance therefrom is formed a slot' 5, leaving a comparatively narrow strip extending between the lateral edges in the upper face of which-is formed a series of grooves 4: each lying in a radius of the circle'deining the end of said plate. Over this strip is placed a clamp 8, the' arms of, which extend through apertures 3 inthe median line of the boa-rd 3, within which they are secured by means of nuts 15.

The lower face of the plate 1 is upwardly inclinedfrom the bolt 6, as indicated at l, which permits the board 3 to be raised from the horizontal, thereby raising the clamp 8 from a groove 4. The board may then be freely swung to any angle'desired with reference to the plate, when it may again be anchored in agroove 4 at the corresponding angle.

By means of the structure shown a foot board is provided which can be swung to any angle desired and firmly anchored there upon a head piece which is adapted to cut, under the force of the weight vupon it, into the stump of a tree, upon which it rests as a fulcrum, while the upturned terminal portion automatically engages with an upward thrust into the upper face of thenotch. The rounded lower face of the head portion permits the device to be swung upwardly upon the terminus as a center, and therebyy readily removed.

Having described my invention, what l[ claim, is

1. A foot board of the character referred to comprising a main plate terminating at its forward vend in a pair of bearing edges spaced apart and adapted to rest upon the supporting surface and turned upwardly to form two upwardly directed holding points adapted to enga-ge the upperside of a notch, and a foot board secured to said main plate.

2. A foot board of thecharacter referred to comprising a main casting having a rearwardly projecting plate or portion adapted to have attached thereto a foot board and having its forward portion formed into a toe-like form concaved on its under side, longitudinally thereof, to form two side holding edges spaced apart and upturned at les its forward end and formed into upwardly said strip in said grooves and secured in directed holding points spaced apart, and a said board, whereby the latter may be raised board attached to said rearwardly projectf from the horizontal to disengage the clamp, ing,` portion. to permit it to Swing horizontally.
