WILLIAM FRANK, OF SPARLAND, ILLINOIS.

DEVICE FOR STRETCHING ROOFING.

To all whom it m an concern:

Be it known that 1, WILLIAM FRANK, a citizen of the United States, residing at Spar-land, in the county of Marshall and State of Illinois, have invented certain new and useful Improvements in Devices for Stretching Roofing; 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a p art of this specification.

This invention relates to new and useful improvements in devices for stretching sheets of roofing material and comprises various details of construction, combinations and arrangements of p arts which will be hereinafter fully described and then specifically defined in the appended claims.

My invention is illustrated in the accomp anying drawings, in which Figure 1 is a perspective view showing the application of the apparatus to the roof of a building. Fig. 2 is an enlarged detail perspective view of the means for clamping and holding the paper. Fig. 3 is a detail view showing the sectional clamping arms pivoted together, and Fig. 4 is an en. arged detail view showing the crank and handle for operating the shaft.

Reference now being had to the details of the drawings by letter, A, A designate the legs of the apparatus having spurs A at their ends adapted to engage the roof in the manner shown in Fig. i of the drawings. The upper ends of said legs have a casing 13 fitted thereto and a Windlass is journaled in suitable hearings in the castings D which are fastened to said legs. Fastened to the casing B is a rod E having a hook E at one end upon which the pulley F is mounted. A cable G passes about said pulley and is adapted to wind. upon the windlass C. A handle H is mounted upon one end of the Windlass C, being held by means of a nut H upon the threaded end of the Windlass, and a ratchet wheel I also rotates with the Windlass and a pivotal pawl J serves to prevent the ratchet from rotating in one direction. A spring- Specification of Letters Patent.

pressed pawl K carried by the handle serves to engage the teeth of the ratchet and is adapted to cause the Windlass to rotate in one direction with the handle.

N and N designate two angled clamping bars pivoted together, said bar N having one end N cut away to allow the end of the other bar to turn freely upon its pivot and O is a cam lever pivoted to the other end of bar N. The bar N has one end cut away as at Q to allow the two bars to come frictionally in contact with each other without interference with the cam lever. Said cam lever, which is recessed on the under side at J, is adapted to be swung upon its pivot over the horizontal face of the bar N to hold the two bars in clamping relation with the paper, desig nated by letter T, clamped intermediate the same. A rope R is fastened to the eyes S upon the bar N and to which the cable G is fastened.

In operation, the roofing paper having been placed intermediate the two clamping plates and the cam lever thrown around into a locked position, thus securgly causing the plates to clamp the paper, the paper may be stretched by the operator turning the windlass through the medium of the crank handle, thus drawing the paper taut and, when in such relation, the same may be conveniently fastened to the roof.

By the provision of the apparatus shown and described, it will be noted that the device may be utilized conveniently by its projecting over the cornice or the end of the roof so that the paper may be drawn taut in different directions.

What I claim to be new is 1. An apparatus for stretching sheets of roofing paper, comprising legs provided with spurs adapted to engage a roof, a Windlass journaled on said legs, a pulley upon the latter, a cable passing about the pulley and winding upon said Windlass, clamping members pivoted together, means for holding said members in clamped relation, and connections between said clamping members and cable, as set forth.

2. An apparatus for stretching sheets of roofing paper, comprising legs provided with spurs adapted to engage a roof, a Windlass journaled on said legs, a pulley upon the nections between the cable and clamping 10 latter, a cable passing about the pulley and members, as set forth.

Winding upon said Windlass, a crank loosely journaled upon the Windlass, a ratchet Wheel fixed to the latter, a pawl engaging the ratchet, and a spring-pressed pawl mounted upon the handle for engagement with the ratchet Wheel, clamping members adapted to engage and hold a sheet of paper, and con- In testimony whereof I hereunto afllx my srgnature 1n the presence of two wltnesses.

WILLIAM FRANK.
