No. 416,383. Patented Dec. 3, 1889.

CARPET-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 416,383, dated December 3, 1889.

Application filed July 13, 1888.

T0 all whom it may concern:

Be it known that I, FRANK J. SWART, of the city of Auburn, New York, have invented certain new and useful Improvements in Carpet- Stretchers, of which the following is a description, reference being had to the accompanying drawings, forming part of this Specification, in which Figure 1 is a side view of my invention with the Striker on its rest. Fig. 2 is a top view of the same. Fig. 3 is a side view with the striker down, and Fig. 4 is a detail view of the strikercatch.

The object of my invention is to construct a carpet-stretcher which may be operated to secure the carpet in positionafter stretching it, so as to enable one person to stretch and hold the carpet stretched until it can be secured by tacks or other suitable means. This result I accomplish by the use of the withindescribed mechansm, in which A represents the handle; B, a frame tached thereto.

C is a comb of stout teeth, whereby the carpet is grasped and stretched by pushing upon 'said handle.

D is a striker-arm provided with a crosshead E, which is provided with sharp teeth or prongs e e. This striker is hinged to the frame B at f f, and the hinge is provided with two springs G G coiled thereupon, one end of each of which is secured to the pintle F and the other end of the springs is secured to the eyes ff, so that when the striker is raised by drawing back the cord H, which is secured to the standard K upon the cross-head E, and is then liberated, the resiliency of the said springs will throw the striker forward and strike the prohgs e e through the carpet and into the floor, thereby securing it in its stretched position. A trippingcatch L is pivoted in front of its center to the arm D and bears a lo g m, which engages a rest n, secured Seral No. 279,849. (No model.)

upon the frame at C. This catch is held in its horizontal position by springs s s, which are attached thereto behind its pivotal point p. By this construction the striker-arm when lowered gently upon the catch L will be sustained by it upon the rest a; but when its descent is rapid, as when it is raised and libererated to strike, it will trip the catch L and pass the rest 'n and strike the prongs e e into the floor.

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

1. In a carpet stretcher, the pivoted or hinged striker-arm D, having the cross-head E, which is provided with a series of holding teeth or prongs e e.

2. In a carpet-stretcher, a hinged or pivoted striker-arm D, provided with the crosshead E, which is provided with a series of holding teeth or prongs, in combination with the graspingteeth C, secnred to the frame which carries the striker-arm.'

3. The combination of the frame provided with holding-teeth, and the striker-arm provided with the cross-head E, having a series of holding-teeth e e thereupon and pivoted or hinged thereto, with a spring or springs, whereby the Striker is actuated.

4. In a carpet-stretcher, the combination of the frame B, the striker-arm D, having a crosshead E, provided with a series of teeth e e e and pivoted to said frame, having a trippingcatch L, held normally so as to support said arm upon said frame, but pivoted thereto, so as to enable it to turn and pass said frame, and a spring or springswhereby said catch is returned to its normal position.
