RIPPING BAR Filed Feb. 27, 1952 lll li'einaiez'ia INVE NTOR BY I I ATTORNEYS Patented June 1, 1954 UNITED STATE ATENT OFFICE 1 Claim.
This invention relates to a prying or ripping bar, the primary object of the invention being to provide a bar of this character, which may be positioned to straddle one edge of a studding, with the arms of the ripping bar extending forwardly in contact with the under surface of the wall board being removed, so that by swinging the handle of the bar downwardly, the arms of the bar will pry the wall board free of the studding without danger of splitting the wall board.
An important object of the invention is to pro- Vide a prying bar of this character, wherein the ends of the arms of the tool are constructed to provide claws, which are so constructed and arranged that after a board has been loosened and the nails have been partially removed the claws may be now used to extract the nails to obviate any danger of splitting or disfiguring the wall board being removed.
With the foregoing and other objects in view which will appear as the description proceeds, the
invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangemnt of parts without departing from the spirit of the invention as claimed.
Referring to the drawing:
Figure 1 is a, perspective view of a prying bar constructed in accordance with the invention.
Fig. 2 is a side elevational View thereof, illustrating the tool as positioned for prying a wall board from the studding.
Fig. 3 is an enlarged elevational view with one of the arms broken away illustrating the claw structure.
Referring to the drawing in detail, the ripping bar comprises the handle 5 and the U-shaped head, indicated generally by the reference character 6. The head 6 comprises the cross bar 1 and integral forwardly extended arms 8, the arms 8 being substantially long so that they will move a substantial distance under the wall board being removed, providing a wide bearing surface between the tool and wall board, to prevent splitting of the wall board.
As shown, the arms 8 are extended at an oblique angle with respect to the handle and the inner end of the head is curved slightly upwardly at 9, so that the fulcrum provided by the cross bar 1 is elevated or slightly ofiset, with respect to the arms 8, to the end that when the arms 8 are p0- sitioned to pry a wall board from the studding, the contact between the arms and inner surface of the wall board, which in the present showing is indicated by the reference character A, is throughout the lengths of the arms.
The ends of the arms 8 are flattened and split, providin claws 9, the space between the claws 9 being equal to the space between nails used in securin the wall boards to the studding It, so that after a wall board has been pried upwardly a distance to cause the nails to extend above the wall board, the tool may be positioned so that the claws 9 will move under the nails, which will be pried from the studding when the handle 5 of the tool swings downwardly. Thus it will be seen that under conditions where the nails and wall board have become deteriorated, the wall board and nails may be readily removed without bending or disfiguring the wall board, which would result when nails become so embedded in studding that the nail heads move through the board when the board is pried from the studding.
From the foregoing it will be seen that due to the construction shown and described, I have provided a tool for prying loose wall boards or studding, the construction of the tool being such that the long arms 8 thereof engage the wall board throughout substantially the entire width thereof to insure against splitting the wall board when the lever is swung downwardly in prying the wall board loose.
Having thus described the invention, what is claimed is:
A prying bar of the class described, comprising a handle, a cross bar at one end of the handle providing a fulcrum, a pair of spaced prying arms extending from said cross bar and offset downward- 1y with respect to the cross bar.
