l My present invention relates to an improved nail puller of the type especially adapted for use in razing frame building structures so that added leverage may be obtained to separate nailed lum-v ber sections and to facilitate the removal of nails from the lumber.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within Ythe scope of the appended claims.

In the drawings:

Fig. 1 is a side elevational view of the device of my invention.

Fig. 2 is a top plan view thereof.

Figs. 3 and 4 are transverse vertical sectional views at lines 3--3 and 4-4 of Fig. 1.

Referring now to the drawings wherein I have illustrated the present preferred embodiment of my invention, I employ a bar 2 of metal construction rectangular in cross section, having angular end portions 4 and 6 substantially parallel with each other.

The extremity of the end 4 is tapered as at 'I and terminates in the claw 8. 'Ihe extremity of end 6 has pivotally secured thereon by pin I0 a fulcrum plate I2 by means of the vertical arms I 4. The pivot point is so located that the fulcrum plate may not pivot over the extremity of the end portion 6 but may rock with relation to the bar end.

Also on the bar I provide a sliding fulcrum block I6 having a central opening IBKfor the bar, the block tapering upwardly at 20 to the claw 22. A laterally extending base 24 is integral with the block and the adjusting screw 26 extends through the base into the opening I8 for engagement with the bar. Obviously by loosening the screw 26, the block may be slid along the bar to the desired point and secured by tightening the screw.

Thus either claw as best located for the particular job may be employed to extract nails, and the bar may be used with thefulcrum block in any selected position to enable the operator to pry apart nailed pieces or sections of lumber by use of the claw 8. If the claw 22 is used the fulcrum plate I2 will permit the bar to be raised on the pin I0 in the usual manner to pull nails or pry apart nailed pieces or sections of lumber. In this instance the block I6 will be reversely Ymounted on the bar from the position as shown in the igures. The bar can also be pivoted upward on the pin I0 to permit adjustment of the block I6 on the bar, as previously described.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

A wrecking bar comprising an intermediate section and end sections angular to the intermediate section and substantially parallel with each other, a fulcrum plate having upstanding vertical arms between which one end section of said bar is passed, a pin passing through said arms and the end section of said bar to pivot said bar for rocking motion in relation to said plate but prevent- REFERENCES CITED The following references are of record in the le of this patent:
