I CLAMP. No. 342,529. Patented May 25, 1886.

WITNESSES INVENTOR ATTORNEYS.

provided with a curved arm projecting from UNITED STATES JOHN B. MCRAE, OF MOUNT HOLLY, ARKANSAS.

CLAMP.

.ilPECII-ICATION forming part of Letters Patent No. 842,529, dated May 25, 1886.

- Application filed January 19, 1856.

To all whom it may concern:

Be it known that I, JOHN B. lVIORAE, of Mount Holly, in the county of Union and State of Arkansas, have inventeda new and useful Improvement in Flooring-Clamps, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a perspective view showing my improved flooring-clamp in use. Fig. 2 is a side elevation.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

The object of my invention is to provide a simple and effective means for forcing the joints of flooring or ceiling together as they are laid; and my invention consists in a lever having at its extremity a lateral point, and

the side of the lever at right angles, and bent inward toward the lever and pointed, the point of the end of the lever and of the curved arm forming a fulcrum for the lever by the engagement of the points with opposite sides of the joist, the points of the curved arm and the lower end of the lever being disposed or arranged in different planes, and all being made in one piece.

Thelever A. which is formed of iron or steel, is provided with a point, a, at the end thereof, which projects laterally from the body of the lever, and is bent outward slightly beyond the end of the lever.

On the side ofthe lever A near the pointed extremity a curved arm, B, projects at right angles, and its extremity carries a point, I), which is directed toward the body of the lever 1 Serial No. 1E9,0II3. (No model.)

A, and is located a ove the point a. The space between the points cab is sufficient to admit of placing the lever on a joist with the points on opposite sides of thejoist, as shown in Fig. 1, when; by swinging the lever in the direction indicated by the arrow, the points are made to enter the sides of the joist sufficiently to form a fulcrum for the lever.

By pushing the long arm of the lever forward against the edge of the strip of flooring or ceiling, or against a block placed on the edge of the strip, the strip of flooring may be forced against the edge of the strip last laid and held while itis nailed, so that a perfect joint is secured. i

My improved flooring-clamp requires no adjusting screws or wedges or other auxiliary devices for securing it to thejoists. It in 1y be quickly applied and removed, and it may be made so small and light as to be readily portable. 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

As an improved article of manufacture, a floor-clamp consisting of the lever provided at its one end with a lateral point, and a short distance from and in alignment with said point with an arm having a downwardextended portion having an inwardly-projectingpoint arranged in a plane forward of and above the point of the lever, substantially as and for the purpose set forth.

JOHN B. MORAE.
