BOARD-STRIPPING DEVICE.

Application led June 12, 1922. Serial N'O. 567,870.

To all whom t may concer/n.'

Be it-known that I, THOMAS CAMERON, a

, subject of the King of Great Britain, and

resident of Bennington, in the State of New Hampshire, United States of America, have invented certain new and useful improvements in Board-Stripping pevices, of which the ollowing is a specification.

This invention relates to improvements in board stripping devices, and has for its objects to providev a means whereby the boards -used in certain frame work 'can be torn down without being damaged.

In taking oit the ledger boards used for staying posts under floor forms, the present cost of lumber makes it exceedingly desirable that these boards should be saved and used again. It is the 'purpose of this invention to provide a device designed to be used in order to remove the boards from the staying postswithout damagingythe boards. f.

Further objects are to provide -a,board stripping device consisting of shank carryying an arm having its two ends curved in opposite directions, andpivotally carrying someboard engaging members.

Further objects are to provlde in combination with the board stripping device, a nail pulling device. l

Further objecls are to provlde a p1' 7bar 1n combination with the-improved board stripping device.

Further objects arp to provide'a board stripping device, that is simple in construction, not liable to go out of repair, and generally to adapt the several parts to better perform the functions required of them.

lVith' thel above and other objects in view, the invention consists essentially of the improved construction, hereinafter described in detail in the accompanying specification and drawings.

In the drawings;

l Figure 1 is a perspective view of the i1nproved board stripping device in use.

Figure 2 is a perspective view of the same taken at a different angle.

Figure 8 is a side view of the improved board stripping device, shown partly in elevation and partly'in section.

Figure 4 is an end elevation of the same.

Like characters of reference indicate, cprresponding parts in all the figures.

Referring to the drawings, A represents the improved stripping device, comprising a shank 10, which is formed integral with an obliquely disposed arm 11. ,It desired the shank 10 instead of being made integral with the. arm 11 may be connected to the same by any suitable means. As' shown in the drawings, thc connection between the. shank 10 andthe arm 11 is made intermediate of the length of the latter, and the arm 11 is formed with its'two extremities 12 and 13 curved in opposite directions.

Pivotally mounted on thecurved portion 12 of thev arm 11 as at 14 is a board en-v gaging member 215 which may be formed of a disc having its edges bent .upwardly in ordervto' form a channelfshaped member.4 The-curved extremity 13 of the arm 1 1 is similarly provided with a board engaging' member 16 pivotally mounted as at 17.

'lhevarm 11 is provided intermediate of itsv length with two pins 18 and 19 extending' in opposite directions, and on each side' .of

the arm 1'1, the pins 18 and 19 are designed to provide a fulcrum for. the device, and when the same is `in use, the pin 18 or the pin 19, as the case may be is engaged with the staying post 20, and the board engaging `niexnber l1G is brought into bearing engagement vwith the board 21 designed to be stripped ofi the post 20.1 The shank 10 is then forced downwardly, and the pin 1'8 in engagement with the postQO acting as a fulcrum, the curved portion 13 of the arm 11 will be forced forwardly, thus causing the board engaging member 16 to push forward on the board 21 and tear itoii the post 20.

The shank .10 may be tapered to a point 22 which is bifurcated as at 23 in order to provide a nail pulling device. lVhen this board stripping device is being used, the pin 18 is engaged with the post 20, and they board engaging member 16 is brought into bearing engagement with the board 21, and the shank 10 being forced downwardly the pin willvact as a. fulcruln, andthe board 21 would be torn from the post 20 through the force applied by the board engaging member 16 for the board and post to be placed adjacent another wall as o'lften'hal'ipens in concrete work, .the board stripping device may be used as shown in Figure 2 ofthe drawings, and the pin 18 or the pin 19 being placed in engagement with the frontfaceof the post 2U. the board engaging' member 15 is `brought into bearing engagement with the act as a fulcrum, and the curved portion 12 of the arm 11 will force the board engaging member 15 forwardly, and the same being applied against the board 21 will tear the same from the post 20.

The bifurcated end 23 of the shank 10 may be used when the'case presents itself to pull nails 0E the posts 20, and the shank l0 of the 4device may also be used as a prying bar. In practice it has been found that this method 'of removing the boards from `the posts results'in a much lower-cost than knocking the boards off with a hammer. As this removes the boards undamaged, it has the further advantage of conserving the timberv supply, and thus makin a still greater reduction in the cost'of t e operation. Y

As many changes could be madev in the above construction, and many apparently Widely different embodiments of my invention, Within the scope of the claims, constructed without`departing from the spirit or scope thereof, it is-,intended that all matter contained in the accompanying specification and Adrawings shall be interpreted .as illustrative, and not in a limiting sense.

f f What I claim as my invention is:

' l. A board stripping device, comprising a shank, an obliquely disposed arm rigidly connected intermediate of its length to one end of the shank, means pivotally mounted at one end of the arm, designed to engage a board, and means on the armadapted to provide a fulcrum.

2. A board stripping` device comprising a shank, an obliquely disposed arm, rigidly connected intermediate of its length, to one mesme end of the shank, means pivotally mounted at one end of the arm designed to engage a board, and a pin extending on both sides of the arm, as and for the purpose specified.

3. A board stripping device comprising a shank, an obliquely disposed arm rigidly connected intermediate of its length to one end of the shank, and having its extremities curved in opposite directions, means pivotally mounted at the ends of the curved arm to engage a b oard, and means on the arm adapted to provide a fulcrum.

4.' A board stripping device, comprising a shank, an obliquely disposed arm rigidly connected intermediate of its length to one end of the shank, a board engaging member pivotally mounted on each end of the arm, and means on the arm adapted to provide a fulcrum.

5. A board stripping device, comprisin a shank, an obliquely disposed `arm rigidly connected intermediate of its length to one end of the shank, .and having its extremities curved in opposite directions, a board engaging member pivotally connected to each end of the curved arm, and a pin extend-
