Description

P. TOWNIL L WRECKING BAR Jan. 10, 1950 -Filed Oct. 10, 1946 f ZN Inventor p952) '7'0wn/a'ZL attorney Patented Jan. 10, 1950 WRECKING BAR Peter Townill, Plainfield, 111.; John Townill administrator of said Peter Townill, deceased Application October 10, 1946, Serial No. 702,465 2 Claims. (Cl. 254131) The invention relates to wrecking bars, particularly adapted for ripping flooring, and has for its object to provide a device of this kind comprising a U-shaped frame adapted to arch and seat on a rafter with its arms beneath a floor board, and a pivoted lever pivoted to the arms, adjacent their forward ends, and having stops for engaging the upper sides of the arms for rocking the U-shaped frame upwardly on the transverse portion of the frame, resting on the upper side of the rafter.

A further object is to pivot the spaced hooked arms of the lever to the frame arms, and to provide the spaced arms with outwardly extending lugs or stops, adapted to engage the upper sides of the frame arms during a prying operation. The hooked arms allow the frame arms to be placed a substantial distance under the floor boards when desired.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Figure 1 is a side elevation of the wrecking bar, showing the same in position, straddling a rafter.

Figure 2 is a perspective view of the lower end of the wrecking bar.

Figure 3 is a vertical longitudinal sectional view through the lower portion of the wrecking bar.

Referring to the drawing, the numeral I designates a fioor rafter, and 2 transverse boards to be ripped therefrom during a wrecking operation.

The wrecking bar comprises a U-shaped member 3 formed from spaced arms 4, adapted to be placed under the boards 2, and at opposite sides of the rafter I. Arms 4 are connected together by a transverse member 5, which rests on the upper side of the rafter I, and forms the fulcrum point during a prying operation. By positioning the arms 4 on opposite sides of the rafter l, side displacement is prevented, and at the same time the bar can be moved forwardly towards the work for successive prying operation.

Pivotally connected at 6 to the inner sides of the arms 4 are downwardly and upwardly extending U-shaped members I, which U-shaped members terminate in upwardly extended spaced arms 8, connected to the handle member or lever 9 of the device. When the lever 9 is moved in the direction of the arrow a, the outwardly extending lugs It] will engage the upper sides of the arms 4, and a continued movement will rock the frame 3 on the cross member 5, thereby forcing the forward ends of the arms 4 upwardly, for prying the boards 2 from the rafter. It will also be noted that successive operations can be accomplished by simply forcing the frame forwardly on the rafter and moving the lever.

From the above it will be seen that a wrecking bar is provided which is simple in construction, positive in operation, and one which straddles the rafter and held against lateral displacement or tilting during a prying operation.

The invention having been set forth what is claimed as new and useful is:

1. A wrecking bar comprising a rafter supported member, said member comprising spaced bars adapted to be positioned on opposite sides of a rafter in spaced relation thereto, the rear end of said bars being connected together by a transverse member adapted to arch the rafter, the forward ends of said bars being adapted to engage under a floor board on the rafter at opposite sides of the rafter, a lever, said lever having its lower end bifurcated thereby forming spaced arms between which the rafter is received, said lever curving downwardly, forwardly and upwardly and hingedly connected to the spaced bars adjacent their forward ends, said arms of the bifurcated lever being provided with stops means for engagement with the spaced bars and forming means whereby the forward ends of the spaced bars will be forced upwardly against the floor board upon a rearward and downward movement of the handle.

2. A device as set forth in claim 1 wherein the stop means carried by the spaced arms of the bifurcated end of the lever comprises outwardly extending lugs carried by the outer side of the arms and in the path of the upper sides of the spaced bars.
