UNITED STATES PATENT OFFICE.

OSCAR L. SPRAGUE, OF ANDOVER, OHIO, ASSIGNOR OF` ONE-HALF 'IO E. WATSON MORLEY, OF SAME PLAGE.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent N o. 326,063, dated September 8, 1885.

Application tiled May 12, 1885.

rs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specication.

My invention relates to improvements in carpet-stretchers, and is designed to produce a stretcher by which comparatively great power may be obtained, the carpet held in the stretched condition while the slack is further stretched, and a means whereby the ad-V vancement and retention of the device in the advanced position is facilitated.

In describing the device reference is had to the annexed drawing, in which is represented a perspective view of the device.

The frame A has at one end sharpened pins or hooks B, for securing it in position, the

said pins or hooks being driven in the floor. At the other end of the frame is a roller, C, by means of which the moving of the device is facilitated.

On suitable crosspieces is supported the sector-rack D, to the center E of which is pivoted the lever F, which straddles said rack. The lever carries a pawl, G, which engages with the sector-rack.

Pivoted adjustably to the lever is an arm, H, preferably made of two parts, so as vto straddle the lever. The arm carries a head, I, which is provided on its under side with a number of sharpened pins or other means of engagement with the carpet.

To each side of the frame are pivoted arms K, the free ends connected by a cross-piece or head, L, provided with pins similar to the head I. Its movement is restricted by guides M, engaging with pins on the frame.

A forward movement of the lever will cause the stretcher to advance, thus stretching the carpet, the rack and pawl preventing a retrograde movement. The retaining-head L is (No model.)

then forced into the stretched carpet and the stretcher loosened to take a fresh hold on the carpet. When suciently stretched, the carpet may be tacked or otherwise secured and the device removed to another position.

I am aware that it is not new to provide carpet-stretchers with levers, stretching-heads connected thereto, and racks for retaining pawls on said levers, which latter are connected to and supported by suitable frames,

which are provided with pins which enter' the oor and retain the device in position while the carpet is being stretched; hence my invention does not, broadly, cover such constructions. Y

1. A carpet-stretcher consisting of a frame provided with retaining pins or hooks at one end and a roller at the other, a stretcher proper-pivoted to a lever, a rack to which ,the lever is pivoted and pawl-retained, and a pivoted holder,substantially as and for. the purpose specified.

2. A carpet-stretcher consisting of a suitable frame, a lever pivotally supported in said frame, a stretcher-head connected directly to said lever, anda holder-head having a pivotal connection to the frame independent of said stretcherhead, substantially as and for the purpose specied.

3. A carpet-stretcher consisting of a suitable frame with retaining hooks or pins at one end and a roller at the other, a sectorrack supported by said frame, a lever straddling said rack,4 pivoted to its center andA pawl-retained, a stretcher-head having pivotal connection to said lever, and a holderhead having pivotal connections to said` frame, substantially as and for the purpose specified.

In testimony whereof I alx my signature,

in presence of two Witnesses, this 27th day of 90 April, 1885. y
