Application June 12, 1953, Serial No. 361,365

2 Claims. (Cl. 254- -131) My invention relates to an improvement in salvage wrecking tools. An object of my improved salvage wrecking tool is to provide a tool of the kind mentioned that may be used in wrecking wood buildings and may be more particularly used for taking up flooring boards, fioor sheeting boards, wall sheeting boards, roof sheeting or stripping boards and the like.

A further object of the invention is to provide tool of the kind mentioned that is strong, durable, light in weight, simple in construction, highly eficient in its work, one that can be easily and quickly compacted for storage or transportation as well as being a tool that can be inexpensively manufactured and sold. These and other objects of the invention will be more fully described and xplaincd as this description progresses.

New referring to the accompanying drawings in which similar numerals of reference designate the same parts throughout the several figures of thedrawings:

Fig. 1 is a detail top plan view of the tool.

Fig. 2 is a detail side view of the tool.

Fig. 3 is an enlarged detail side view of one of the lifting arms and lifting foot, there being two of these lifting arms and feet that are duplicates of each other.

Fig. 4 is a top plan view of the members shown in Fig. 3.

Fig. 5 is a combination sectional view through the tool and a side view of the handle member of the tool, the view being as seen from the line V-V in Fig. l and looking in the direction of the arrows.

Fig. 7 is a detail sectional view through a portion of the tool, the view being as seen from the line Vll-Vll in Fig. 4 and looking in the direction of the arrows.

Fig. 8 is a perspective view of the tool and showing the tool in position for lifting a board in the wrecking operation.

Fig. 9 is an enlarged detail plan view of a lifting finger that may be substituted for the lifting arms and feet shown inFigs. l, 2, 3, 4, 6, 7 and 8.

Fig. 10 is a side view of the lifting finger shown in Fig. 9.

In the drawings the tool is shown as having a multisided, preferably a hexagonal shaped twist shaft 12 on which is slidably positioned a twist sleeve 13 that has an opening 14 therethrough that is the same shape as the twist shaft 12 and is of such size that the twist shaft 12 may be slidably received therein. The twist sleeve is provided with a thumb set screw 15 that is threaded through the wall of the twist sleeve 13 so that the end of the set screw 15 will bear against the side of the twist bar 12 to bind and hold the twist sleeve 13 inselected adjusted positions along the twist shaft 12. The twist sleeve 13 is provided with a pry lever 16, one end of which is rigidly attached to, or preferably made integral with the twist sleeve 13. The other end of the ory lever United States Patent 0 16 is provided with laterally projecting handle elements 17 by which the tool may be actuated.

The tool is further provided with a pair of lifting

arms

18 and 18a, each of which are identical and have identical associated parts. The arms are preferably made in a curved shape as shown in Fig. 3 for the strength that can be built into the arms 13 and 13a and also it is easier to place the tool under the board 28 that is to be lifted. One end of each

lifting arm

18 and 18a is rigid, preferably integral, with its respective twist sleeve 19 or 1%. Each of the lifting arms lid and 18a, twist sleeve 19 or 19a is provided with an externally annular sleeve extension 2i) on which is revolvably mounted a roller sleeve 21. The roller sleeve 21 is held in place on the sleeve extensions 2% by means of a split spring ring 22 that is seated in an annular groove 23 in the end of the sleeve extension portion Eli and projects therefrom enough to engage the end of the roller sleeve 21 to retain the roller sleeve 21 on the sleeve extension 2%. Each twist sleeve has a thumb screw 19:: threaded through the Wall thereof to engage and bear against the twist shaft 12 as a means of holding and locking the twist sleeves id and 19a in adjusted spaced apart positions on the twist shaft l2 for purposes that will later he described.

On the outer end of each lifting arm l8 and 18a is carried a self adjustable lifter foot 24. Each lifter foot M is provided with a pair of depending and spaced apart lip-like supporting elements 2-5 and 25a that straddle the outer end of their respective lifter arm 1% or Eda to provide a. pivotal mounting of the lifter feet on the outer end of their respective lifting arms lid and lda. A pivotal mounting pin 26 passes through the lifter feet support lips 25 and Erica at a point in rear of the center of the lifter feet therefor the forward ends of the lifter feet 2 are heavier than the rear ends and the lifter feet will therefore normally tip forward to make easier the operation of moving the lifter feet under the board 28 that is to be lifted. The forward ends of the lifter feet 34 may also be provided, if desired, with additional weight elements Z ta that will make more positive the tipping action of the lifter feet 24-.

The extreme outer end of each lifter arm 1% or the is provided with a top element 13x that is an integral part of its respective arm 13 or 13a and is adapted to be engaged by the under side of the lifter foot 24; to limit the degree of forward tipping of the lifter foot 24.

The tool as above described works good in such places where the lifting

arms

18 and 18a and their lifter feet 2 can be easily slipped under the board that i to be removed as shown in Pig. 8, however in such a case as the lifting or removal of flooring from the floor sheeting boards there would be no space in which the lifter feet 24 could be entered between the flooring boards and the sheeting boards, therefore I have provided lifter lip elements 2d such as shown in Figures 9 and 10 that can be substituted for the lifting legs 13 and 13a and the lifter feet 24 as will later be described.

in Figures 9 and 1-0 is shown a twist sleeve 192: which is made the same as the twist sleeves l9 and 19a and are receivable and adjustable on the twist shaft 12 the same as the twist sleeves l? and 19a. The tool is provided with two of the twist sleeves 19x each of which are receivable and adjustable stationable on the twist shaft 12, the same as the twist sleeves l9 and 1%. Each twist sleeve lldx is provided with a thin lift leaf as, one end of which underlies the twist sleeve 19.xand is rigidly attached, preferably welded, thereto.

Now to prepare the tool for use the twist sleeve 13 may he slipped onto and to the central portion of the twist shaft 12 whereupon the thumb screw 15 may be turned to set or look the twist sleeve l3 and handle in thereon in their adjusted position on the twist shaft 12.

This having been done the twist sleeves 19 and 19a may be slipped one on each end of the twist shaft 12 to such a spaced apart position that the roller sleeves 21 will, when the tool is in use, rest on any two adjacent joists 2'7 and 28a and the lifting arms 18 and lilo will project under the sheeting board 28 that is to be lifted. The relative angular position of the pry lever 16 and the lift ing

arms

13 and 18a may be adjusted to the convenience of the user of the tool by selecting the position in which the pieces 19 and 19a are placed on the twist shaft 112 at the time of assembling the tool.

The tool having been assembled as above described, is now ready for use and may be used by the user of the tool who may hold the tool by the pry lever is in such a position that the roller sleeves 21 will rest on the joists 27 and 2711 so as to support the tool, whereupon the tool may be moved to a position that the lifting

arms

18 and 18a and the lifting feet 24 thereon are under the board 28 wherefore the pry lever 16 may be rocked in a direction away from the sheeting board 28 at which time the lifting arms is and Ella and the lifting feet 24 thereon are forcibly rocked upwardly to lift the sheeting board and pull the nails from the joists 27-27a that hold the sheeting board 23 thereon. This having been done the board 28 may be moved and the tool moved to engage and lift the next board 28a the same as the board 23 was removed,

In the case of removing flooring and due to the fact that the flooring lays flat against and is nailed to the floor sheeting ZS-ESQ it is impossible to enter the lifting

arms

18 and 18a and the feet 24 thereon between the flooring boards and the floor sheeting 28 and 28a, therefore the twist sleeves and 19a may be removed from the twist shaft 12 and replaced with the twist sleeves 19x on which is carried the lifting lips or leaves 26. This change having been made, the ends of the lips or leaves 26 entered between the flooring boards 28-25% and the flooring board that is nailed thereto and by the application of a little pressure applied against the pry lever 16 and the twist sleeve 13 from the toe of the user of the tool the entire or major portion of the lips or leaves 26 may he slipped beneath the flooring board whereupon a rearward rocking movement of the pry lever in will cause the lips or leaves 26 to rock upwardly and lift the flooring board from the sheeting boards 2828a and in so doing the nails that held the flooring board to the sheeting boards 28-23a will also be pulled and left comparatively straight for easy removal from the floor board. This process of removing boards from the timbers to which they are nailed leaves the boards in a preserved and unbroken condition so that they may be easily cleaned of all nails and the boards are left in a whole and undamaged condition so that they may be again used and serve substantially as good a purpose as new lumber would.

When the tool is not in use the several parts thereof may be disassembled and laid side by side to compact the tool for storage or transportation purposes whereby the tool is easier to handle and take care of.

Now while the tool as shown and described is probably the preferred form of the tool, it is to be understood that such modifications of the tool may be employed as lie within the scope of the appended claims without departing from the spirit and intention of the invention. Now having fully shown and described my invention what I claim is:

l. A salvage wrecking tool or" the kind described; said tool comprising a multi-sided twist shaft, 9. pry lever and a plurality of lifting elements, said pry lever having a twist sleeve being rigidly attached to one end of the pry lever, the opening through said twist sleeve being of such size and shape as to non-revolvably receive and fit said twist shaft, and means carried by the twist sleeve for locking the twist sleeve in selected positions along the twist shaft, each of said lifting elements having a twist sleeve rigidly carried on one end thereof, the opening in each of the last said twist sleeves being of such size and shape as to non-revolvably receive the said twist shaft, and means carried by each of the last said twist sleeves for stationing and holding the last said twist sleeves in selected longitudinally adjusted positions on the twist shaft, the other end of each lifting element having a litter foot thereon for engaging and lifting a board that is to be removed from other elements to which the board may be fixed, each of the last said twist sleeves having an externally annular sleeve extension thereon, roller sleeves, one for and revolvably carried on each extension sleeve, and means for retaining each roller sleeve on its respective twist sleeve extension.
