WRECK-ING TOOL.

Application filed January 11, 1922. Serial No. 528,482.

To all whom it may concern:

Be it known that I JAMES L. lVILmiR, a citizen of the United States, residing at Concord, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in a lVrecking Tool; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

This invention relates to a wrecking bar or tool.

One important object is to provide a tool of this kind having a chisel or claw portion disposed at a right angle to and crossed by the median line of the handle and connected to the handle by a crook or fulcrum bend oifset relatively to the handle to enable the tool to operate in minimum space and to facilitate reception of hammer blows.

Another object is to provide a tool of this character which may be used for the diflerent functions incidental to house wrecking and the like, namely prying of boards apart and extracting of nails or spikes at the same end of the tool to overcome the necessity of reversing it.

A further object is to provide a tool of this character having a chisel end with one .face of the chisel disposed at a right angle 'to the handle and with the chisel slotted so that it may function as a claw.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating one practical embodiment.

In said drawi g's:- Figure 1 is a view in perspective of the improved t0ol;' Figure '2- isa side elevation thereof and Figure 3 is a plan view. Like reference characters designate like orsimilar parts in the difierent views.

\ In reducing the invention to practice, the

tool may be made from any suitable material 1 preferably a metallic bar of anymsuitable cross sectional configuration.

Said bar or tool has an elongated handle portion 10, which is offset at 11 to provide a bend or crook on which the bar may fulcrum and the adjacent terminal of the bar is formed into a suitable tool at 12. It will be seen that the median line of theportion 10 crosses the tool l2'intermediate its ends and that such tool at its free end is disposed on the opposite side of said median line to the said offset portion 11.

The lower edge of the tool 12 as at 13 is preferably flat and disposed at a right angle to the bar 10. The free end of the tool 12 has a feather edge as at 14 and an edge or wall 15 extending upwardly therefrom, being fiat and inclined to thewall 13 forming a chisel. This chisel ispreferably widened as at 16 and intermediate its side edges is recessed or slotted as at 17 to receive a nail or spike to be extracted whereby tool 12 may also function "as a claw.

The end of the bar opposite to the tool 12 may also be utilized as a tool and to this end as at 18 is preferably curved or deflected or formed into a chisel or end substantially similar to that of an ordinary crow bar.

In using the device, the tool 12 may be inserted intermediate boards to pry them or it may be used as a claw to receive and extract nails, in the latter instance the nails being received in the slot 17 and the bar 10 actuated as a lever, fulcruming on the crook at 11. When force is necessary to insert the tool 12 between the boards to engage the head of a nail when the latter is flush with the surface of the :board, the tool 12 may be slightly tilted and a hammer blow dealt on the crook 11 which. will be directly imparted to the tool 12. The particular olfset or crook at 11 effectively reinforces the bar to withstand such hammer blows. tionyas t-hetool 12 serves both as a chisel or the like and as a claw, both prying and extracting functions may be performed while the tool 12 is in the same position so as to particularly avoid the necessity of reversing the bar as must be done where the tool has a claw at one end a chisel at the other end.

In addition, the crook 11 enables further movement and accordingly better leverage of the handle than would be true if it extended at a right angle to the tool 12 and directly or straight from its rear end.

Also as a result of the crook 11, the tool 12 may be better applied to the work especially where minimum space for operation of the tool is afforded.

The tool may be used as an ordinary crow bar or pry by bringing the end 18 into proper relation with the work as will be understood.

Since merely one practical embodiment has been illustrated and described, it is to be In addi- 1 rec understood that changes in the details may of a metallic bar having a handle portion, a tool member disposed transversely relatively to said handle portion, the longitudinal inedian line of said handle portion passing through said tool member, a substantially semicircular crook ofl'sct out of and open at said line conne ting said handle portion and tool nicinl r, the outer main surface of said tool member being substantially flat from 15 the distal end of said tool to said line and being in a plane. substantially at a right angle to the handle, the outer curved surface of the crook merging into said flat main wall substantially at said median line, the inner surface of said tool member extending 'from substantially said line towards the first surface to provide a chisel, and said tool member having its distal end on the side of said line opposite to the crook and being widened and having a slot to permit it to function as an extracting claw.

In testimony whereof I affix my signature in presence of two Witnesses.
