SIDING JACK.

SIDING-JACK.
SPECIFICATION forming part of Letters Patent No. 364,260, dated June '7, 1887.
Application filed February 4,1887. Serial No. 226,573. (No model.)
To all whom it may concern: Be it known that I, EMANUEL1{ERNS, a citizen of the United States, residing at Sibley, in the county of Ford and State of Illinois, have invented a new and useful Improvement in Siding-Jacks, of which the following is a specification. I
This invention is an improvement in dooring, ceiling,vand siding jacksfor carpenters use; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective view of a device embodying myimprovements, illustrating the manner of using the same in laying flooring. Fig. 2 is a top plan view of my improved jack. Fig. 3 is a longitudinal sectional view of the same, taken on line as w of Fig. 2. Fig. 4 is a detail perspective view of the shoe or head.
A B represents a pair of jaws, which are pivoted together upon a bolt or rivet, C. The jaws are arranged at such a distance apart as to admit the insertion of an ordinary piece of studding or joist between them, and the said jaws are provided on their opposing sides, near their outer ends, with projecting studs I).
Thejaw A is provided with a handle, E, and
bears against the opposing side of the arm F,
the function of the said spring being to normally diverge the said arms, so as to open the jaws A and B to their utmost extent.
I represents a shoe or head, which is provided on one side with a longitudinal groove, K, adapted to receive the usual tongues with which flooring, ceiling, and drop-siding boards are commonly provided. This shoe or head I is centrally pivoted on the same bolt or rivet O which is employed to pivot the jaws to gether, and thereby the shoe or head may be turned to any desired angle with respect to the arms and jaws.
The operation of my Invention is as follows: When the board to be forced home is laid upon the studding, rafter, or joist, the operator grasps the handles of the jack with one hand and compresses them toward each other against the resilience of the spring and causes the clamping-jaws to force their studs or points D into opposite sides of the stud, rafter, or joist, the shoe being so directed that the tongue of the board will enter the groove of the shoe. The studs or points D form fnlcrums or pivotal points, upon which the jack is free to turn when it is arranged in this position, as shown in Fig. 1, and the operator then forces the outer ends of the arms inwardly over the board, and thereby causes the shoe or head to bear against the tongued outer edge of the board and force the same snugly into position against the adjacent board, which has been previously secured in place upon the joists, studs, or rafters. In this manner-the tongued-and grooved boards may be laid in position and secured to form flooring, ceiling, or drop-siding very expeditiously.
Having thus described my invention, I claim- 1. In ajack, the combination of the handles E F, having thejaws A B, provided with engaging studs D on their opposing sides, the bolt 0, pivoting the jaws together, the head or shoe I, Ushaped in cross-section, pivoted on the projecting end of the said bolt, and the spring adapted to normally distend theja'ws, substantially as described.
2. A flooring-jack comprisin the jaws A B, pivoted on a bolt, 0, and a h fd or shoe, I, U- shaped in cross-section, i t d also on the same bolt, 0, substantially as set fort 3. A flooring-jack comprising the jaws A B, pivoted together, and a shoe, I, pivotally mounted on the pivot of said jaws, the jaws having handles EF, respectively, and the handle E being provided with a curved loop or guard, G, substantially as specified.
In testimony thatIclaim theforegoingas my own I have hereto aflixed my signatureiu prcs Witnesses:
