Description

Aluig- 87 1933- c. B. PoLHEMUs 1,921,302 y HEADER BOARD STAKE Filed July 27, 195].
I/VVEA/TR /1 Troia/veuf Patented ug. l8, l1933 UNITED .STATES f PATENT-OFFICE i The present invention relates Vparticularly to a stake for use in holding a header board in .position during the construction of a concrete curb, sidewalk, or similar structure.
It is one object ,ofl the invention to provide a stake of the character indicated that may be used repeatedly without material deterioration.
It isv another object of the inventionto provide a stake of the character indicated so shapedy and formed as to be readily driven linto the aground and yet beA firmly imbedded inH the ground and supported against accidental dis- I placement in any direction.
It is also an object of the invention to provide a stake of the character indicated that will be economical to manufacture, strong, rigid, durable, and highly eiiicient in its practical appli# cation.
In the drawing:
Figure l is a side elevation of a stake embodying my invention in position, parts broken away and partly in section. l
Figure 2 is a section on line 2 2 of Figure 1. Figure 3 is a section on line 3 3 of Figure 1. Figure 4Yis `a face elevation of the entering end of the stake.
In the form of the invention disclosed the stake comprises a bar of sheet metal of suitable dimensions having the following,characteristics.'
The center of the bar, throughout its entire length, is flat as shown at 1 and the two side on both sides thereof through the portions 2 2k as shown at 7. The convexity of the side portions 2 2 is increased vat points adjacent the i ving against the soil and holding thebar to its true position. Y
base of the angular edges 7 7 as shown at 8 8 therebycausing theedges 9 9 to make a sharp twist at this pointl as shown at 1010.
In applying the stake it is driven into the ground the desired distance` with the concave sides of portions 2 2 facing the board, and is nailed to the board vwith the iiat portion 1 against the same.
' A bar iormed in this manner may be readily removed from the board when the concrete is set and usedagain. It will not bend VvWhen being ydriven into the ground. A comparatively small area contacts the board, consequently it is easily mounted Vsolidly thereon. Its cross-sectional conformation positivelyinsures its entering the ground in the direction selected, and effectually prevents lateral movement.
vTheloulging shoulders at 8 8 may not always' be provided, but I have found that they counteract the tendency of the angular edges`7 'l to force the entering end of the bar inwardly with respect to the desired position of the board 5, the inner sidesoi the shoulders as 11 11 bear- It is to be understood, of course, that while I have herein shown and described' but one -f specific embodiment of the invention, changes in form, construction and method of application may be made Within the scope of the appended l.
