DISMANTLING-TOOL.

Specification of Letters Patent.

Patented July 22,1919.

Application filed April 1, 1919. Serial No. 288,688.

tains to make and use the same.

The present invention relates to improvements in dismantling tools for use in tearing down woodwork construction, and is intended to be particularly useful in the dismemberment of tongue and groove boards forming floor, ceiling and wall construction.

' dismantling of woodwork construction.

The invention will be more fully understood after reference to the accompanying drawings, in which like parts are indicated by similar; reference symbols throughout the several views, and inwhichz- Figurel isan elevational view of an improved dismantling toolconstructed in accordance with the present invention.

Fig. 2 is an enlarged elevational view, with parts shown in section, of the same, with an extension handle applied thereto.

Fig. 3 is a cross sectional view taken on the line 3 3 in Fig. 1.1

Fig. 4 is a similar sectional view taken on the line inFig. 1; and

Fig. 5 is a transverse sectional view taken on'theline 55 in Fig. 3.

Referring nowmore particularly to the drawings, 1 designates'the'shank of the improved dismantling tool, being formed at one end with a nail extracting claw 2 and with a chisel edge 3 at its oppositeend.

A lower foot 4 is connected to a sleeve 5, which may be slidable on the shank 1 to adinit of adjustment, "or maybe made fixed with respect to the shank 1, as may be desired. As shown in Fig. 2, a spline 6 is recelved into a groove 7 in the sleeve 5, which permits of this vertical adjustment of the sleeve and lower foot 4, while at the same time preventing the rotation of the sleeve on the shank.

A brace 8 connects the lower end of the sleeve 5 with the outer end of the lower foot 4, in order to support the latter where the most strain is received thereon. At its other end the lower foot 4 is formed into a nail extracting claw 9 for use where the claw 2 is not so applicable, as hereinafter set forth.

Above the lower foot 4 is an upper companion foot 10, carried on a sleeve 11 slidable on the shank 1, and also having engagement with the spline 6 in order to prevent the rotation of the sleeve on said shank; whereby the vertical alinement of the two feet may be at all times preserved.

A brace 12 is connected between the upper end ofthe sleeve 11 and the upper foot 10 in order to reinforce the latter. As shown in Figs. 8 and 4 set screws 13 may be employed to bind the sleeves 5 and 11 to the shank 1 after the desired adjustment has been effected. The upper foot 10 is formed with elongated? grooves or guidieways 14 along its opposite longitudinal edges to slidinglyreceive the overturned flanges 15 on an extension toe 16. As indicated in d0tted linesin Fig. 2, this extension toe 16 is capable of being movedback and forth over the guideways 14, and in this manner the length of the upper foot is either enlarged or diminished as required by the width of the boards operated upon, as will be later explained.

A bridgel 17 is connected "between the guideways Men the upper part of the extension toe .16 and carries a set screw 18 which is adapted to engage against the upper face ofthe foot 10 in order to bind the extension toe 16 in the position to which it has been adjusted.

As is apparent from Figs. 1 and 2, the outer free end of this extension toe 16 is beveled, as represented at 19, in order to permit the action of the toe as presently explained.

In Fig. 2 there is shown an extension handle 20 having a angled end 21 provided with

collars

22 and 23, which are received over the upper end of the shank l when the tool is to be used in inaccessible places or at heights requiring increased reach. A set screw 24 may be carried by one of the collars to bind against the shank l 'in order to hold the extension handle 20 in place thereon. The opposite end of the extension handle 20 is formed with a socket 25 of a size to fit the shank 1, and a fastening means indicated at 26 may be employed to secure the socket in place on the shank.

It will be evident that by disengaging the

collars

22 and 23 and reversing the extension handle 20, so that the socket 25, which is in axial alinement with the axis of the handle 20, is received over the upper end of the shank 1, the handle 20 will then extend in a straight line with the shank 1. The extension handle 20 therefore may be connected either in the angular relation shown in Fig. 2, or in a straight line with the shank 1, as various uses require.

In use, the tool is applied as shown in Fig. 1 after the nails have been first extracted from the boards shown in dotted lines at 27 by the claw 2, and the first board pried out of place by the chisel edge 3. The board removed by this chisel edge admits the shank 1 to be passed down through the flooring, as shown in Fig. 1, and the lower and upper feet 4 and 10 are then engaged with the next board 27 in the manner indicated. The lower foot 4 engages beneath the board while the upper foot 10 extends above the same, and the extension toe 16 is so adjusted as to bring its beveled edge 19 just beyond the tongue and groove connection between the board worked upon and that next to the same.

The shank 1 is thereupon lifted, or allowed to exert a lever movement with the end 19 ofthe toe as a fulcrum, and this action will have the effect to lift the board and to with draw the tongue from the groove without.

injury thereto. The tool is worked from one end of the board toward the center, and is then carried tothe opposite end of the board and from'that end likewise worked over to the center of the board. In this manner the board is loosened all along its length gradually and after the center is arrived at, after being worked to from both ends, the board issufficiently loose to be pried entirely out of place and removed from the ceiling- Subsequent boards are similarly acted upon with like results.

In case the boards are of greater width than shown in Fig. 1, the set screws 18 may be loosened and the extension toe 16 set fartherout on the upper foot 10 so as to i always give the beveled edge. 19 a bearing.

The upper :foot,..and. extension toe are 1 also capable of a vertical adjustment by loosening the set screw 13 and raising the sleeve 11 on the shank 1, and this adjustment is advantageous when boards of a greater thickness than indicated in Fig. 1 are to be operated upon.

The sliding sleeves also admit of bringing the feet closer together where the boards are of lesser thickness.

Either the upper sleeve 11 may be shifted to effect this-vertical adjustment, or both the upper sleeve 11 and the lower sleeve 5 may be simultaneously moved as desired.

In dismantling ceiling, the extension handle 20- becomes of great valueas it enables the workman to gain access to the ceiling without the necessity of erecting a scafiold. The angular position of the extension handle 20 is found to be most advantageous in the dismantling of wall boards, as it enables the gap between the lower foot% and upper foot 10 to be-Worked up and down the full length of the wall boards, while at the same time placing the operator in a convenient positionwith respect to the wall and transmitting the force applied in the most effective direction;

The claw 9 is also advantageous in removing thenails from the wall boards, as the sides of the shankl would prevent the convenient operation of the lower nail extractor 2 for this :purpose.

It will probably be found most convenient to reverse the extension handle 20 from the position shown in Fig. 2 in order to bring same in alinement with the shank 1 when ceiling is to be dismantled, as this gives the workman a greater reach and enables him to pull directly downward on the boards, or to rotate the implement about the extension toe as a center with ease and convenience.

It will be obvious that various modifications might be made in the herein described apparatus, and in the combination and arrangement of parts which could be used without departing; from the spirit of my invention, .andI do not mean to limit the invention to such detailsexcept as particularly pointed out in the claims.
