T0 all whom t 'may conce-M1:

Be it known that we, Tinian A.. Pooxi and Jain-1s M. Marone, citizens of the United States. residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Iniprovernents iu iloard-'longnc Cutters, of which the following is a specification, reference being had to the accompanying` drawings.

This invention relates to tools. and particularly to a tool designed for the purpose of cutting or splitting oli' the tongue in matched flooring or sheathing.

It is often necessary in repairing buildings, putting in electric wiring, plumbing, etc., that the matched fiooring he taken up, and in order to do this it necessary to eut or split ott the tongue of one board so as to permit this board to be lifted. The ordinary way of accon'iplishiug this end is to drive a chisel down between the boards, thus splitting oit.' the tongue so that the tongue remains within the one boardv and repeating the saine oj'ieration on the other edge of the board.

The object of the present invention is to provide a tool which is especially adapted lfor this purpose and which will readily cut or split off the tongue without, however, making any large gap between the two boards, and further to provide a tool of this character which may be readily removed and readily put into operation.

A further object is to provide a tool which is so simple that it may be very cheaply made and which is so constructed that there is no danger of the knife being injured by coming in contact with nails used in holding down the sub-fiooring, and in this connection to provide a tool having a horizontal shank portion within which the blade is disposed, the blade having a uniform width throughout its length and projecting beyond this shank portion only sufficient to split a flooring tongue without going into the sub-fiooring, the shank acting as a stop preventing the too great driving in of the blade.

A further object is to provide a device of this character wherein the knife of the blade is removable and replaceable.

Other objects will appear in the course of the following description.

The horizontal portion 1Q at its extremity remote from the handle is upwardly curved, as at 15. This horizontal port-ion 1Q of the metallic rod is longitudinally slitted or kei-fed, as at 16, and disposed within this slit or kerf which extends the full length of the horizontal portion of the bar is the blade 17. This blade may be either beveled upon one face or beveled upon opposite faces, and the blade is held in place within the kerf 16 by rivets, bolts or screws 18. The blade is preferably of thin steel of uniform gauge so that it will not injure the wood when driven in between the joints of a floor.

In the use of this device, the blade is disposed at the joint between two boards and hammer blows struck upon the upper face of the horizontal portion 12 will force the blade downward between the two boards, the blade cutting 'into the tongue at its base and tending to split the tongue from the board,

on which it is formed. As the tongue is split or cut, the blade is shifted longitudinally. In order to remove the blade from the floor so as to permit it to be shifted, it is rocked upon the portion 15 which constitutes a fulcrum. When the blade becomes worn or injured in any manner it may be readily replaced by removing the rivets, screws or bolts 18 and slipping the blade out and slipping a new blade in. The blade 17 is preferably formed with two or more perforations for the passage of thev screws or bolts 18 and one of these is preferably elongated to permit the ready assembly of the blade. The handle 11 is preferably knurled so that it may be readily grasped and the blade held in correct position.
