Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed February 7, 1905. Serial No. 2%.561.

To all whom, it may concern:

Be it known that I, MARTIN O. W ALLUM, a citizen of the United States, residing at Binford, in the county of Griggs, State of North Dakota, have invented certain new and useful improvements in Floor-Jacks; 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.

This invention relates to floor-jacks such as are employed for forcing floor-boards into close contact with the next board, although it will of course be understood that the tool may be used upon siding or wherever else it may be applicable.

The object of the invention is to provide a tool of extreme simplicity, which as an article of manufacture will comprise but few parts and which will be simple and positive in its operation.

in the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both the views, Figure 1 is a side elevation showing the tool in use. Fig. 2 is an elevation looking at right angles to Fig. 1.

Referring now to the drawings, there is shown a floor-jack comprising a presser block or head 5, the face of which is ribbed, as shown at 6, at one side of the head, while from the opposite face there projects upwardly at an acute angle an arm 7, the free end of which is bifurcated to form laterally-spaced ears 8.

.lfletween the cal-s8 is pivoted a hand-lever 9,

one end of which is pivoted between the cars 10, that project upwardly from an anchor plate 11. From the under face of the plate 11 project hook-fingers 12, the free ends of which are turned in a direction away from the head 5, these lingers at one end of the plate projecting beyond said plate, as illustrated.

In the use of this tool the anchor-plate 11 is disposed upon a joist if floor is being laid, and the head 5 is disposed against the board that is to be forced into position for nailing. The lever 9 is then moved with its upper end. in the direction of the head 5, with the result that the head is moved against the floor-board and forces the latter into place.

That is claimed is---- A tool of the class described comprising ahead having a corrugated face at one side and having an integral arm projecting from its opposite side at an acute angle thereto and having spaced cars at its free end, a lever pivoted between the ears of said arm, and an anchor-plate having hook-fingers projecting from its lower face and beyond one end thereof in a direction opposite to the head, said anchor-plate having spaced ears projecting from its face opposite to the fingers, and between which ears the lever is pivoted.

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