J6 s6 @/*Z g Q25-, J E' mgm@ through positioned on the inner surface of the arcuate end I3 and with the slot I2 longitudinally positioned and extended inwardly from the end to a point 22.

Openings

23 and 24 are provided in the sides 25 and 2G, respectively, between which the slot I2 is positioned.

The jaw I4 is provided with a bifurcated upper end, having

side Walls

21 and 28 that straddle the lug I I, as illustrated in Figure 4, and the

walls

21 and 28 are provided with

bolt holes

29 and 30 that receive a bolt 3| extended through the opening 2I in the lug II, and with the bolt provided with a lock nut 32 the jaw may be securely mounted on the handle. The lower end of the jaw I4 is provided with a transversely disposed slot 33 that is shaped to fit over a tongue on the edge of a iloor board, as indicated by the numeral 34. It will also be understood that the jaw I4 may be of any other suitable shape or design.

The floor joist clamp, as illustrated in Figures 1 and 3 is formed with the bar I 5 in combination with the knurled cylindrical elements I6 which are provided with studs 35 and lock nuts 36. The bar I5 is provided with spaced openings 3l' and the studs 35 of the element I5 extend through the opening as shown in Figure 3.

The upper end of the bar I5 is secured in the slot I2 in the arcuate end I3 of the handle by a bolt 38 that extends through

openings

23 and 24 in the sides 25 and 26'in the end I3 of the handle, and the bolt 38 is provided with a lock nut 39.

With the parts arranged in this manner the knurled elements I6 are positioned over the edges of a floor joist 48 and with the slot 33 in the end of the jaw I4 positioned over a tongue of a floor board 34, the handle is actuated in a clockwise direction with the end anchored to the floor joist by the members I5 and I6 and as the movement of the handle is continued the board 34 is forced into position against the edge of the next board.

When laying oor boards over sub flooring as indicated by the numeral 4I the clamping bar I5 is replaced by the point I'I which is mounted in the slot I2 in the outer end of the handle through a tongue 42 that is provided with an opening 43, and a collar 44, between the point and tongue, is positioned against the end of the handle. The point is secured in place by bolts, similar to the bolt 38 passing through the

openings

23, 24, and 43 and secured in the lock nut 39.

The nail pulling jaw I8 as illustrated in Figures l2 and 13 is formed with extended force jaws having beveled inner edges, asindicated by the

numerals

45 and 46 and a V-shaped slot 41 is provided between the jaws for receiving a nail,v

or the like. The jaw I8 is provided with a hub 48 and a tongue 49 with an opening 59 therethrough extends from the opposite side of the position by lll lii

hub, with the opening positioned to register with the

openings

23 and 24 in the end of the handle. With the tongue 49 positioned in the slot I2 in the end of the handle a bolt similar to the bolt 38 is placed through the end of the handle for securing the jaw end position, however, when it is desired to use the jaw, as illustrated in Figure l1, the bolt 38 is removed and the threaded stud 20 of the block I9 is extended through the opening in the

sides

25 and 26 and in the tongue 49 so that the block I9 provides a fulcrum, and with the ful- Crum positioned comparatively close to the jaw an extended leverage is attained whereby the floor boards are readily pried from the joist.

With the parts arranged in this manner the combination tool of this invention is useful for cinching up floor boards whereby the boards are positively held in position while nailing or with the jaw I4 and bar I5 removed the nail pulling jaw I8 may be mounted in the end of the handle whereby the device may be useful as a wrecking bar for pulling nails and the like.

It will be understood that attachments of var-v ious types and forms may be used in combination with the handle whereby the use of the handle may be extended.

It will be understood that other modifications may be made in the design and arrangement of the parts Without departing from the spirit of the invention.

What is claimed is:

In a combination tool, the combination which comprises an elongated handle having an arcuate end with a longitudinally disposed slot extended through the tip of the arcuate end and with a4 lug extended from the inner surface of the arcuate end and spaced from the tip thereof, a bar having openings therethrough pivotally mounted in the slot in the tip of the arcuate end of the handle and extended therefrom, spaced knurled cylindrical elements having threaded studs on the ends thereof positioned in the openings of the bar, lock nuts on the threads of the knurledA cylindrical elements for securing the elements on the bar, and an arcuate gripping jaw having a transversely positioned slot in the end thereof pivotally mounted on the lug extended from the inner surface of the said arcuate end of the handle.
