EDWVARD R. MOSER, OF NAPERVILLE, ILLINOIS.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 634,471, dated October 10, 1899. I

Application filed January 9, 1899.

To all whom it may concern:

Be it known that I, EDWARD R. Mosnn, a citizen of the United States, and a resident -of Naperville, in the county of Du Page and State of Illinois, have invented certain new and useful Improvements in CarpetStretchers; and I do 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 totheaccompanying drawings, and to letters of reference marked thereon, which form a part of thistheir seats and their point portions bent obspecification. v I

Figure 1 of the drawings is a representation of aperspective view showingthe invention as in application; Fig. 2 is a longitudinal section of the invention. Fig. 3 is a transverse section of same.

This invention is designed to provide a carpet-stretcher of improved character; and it consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates a block of hard wood or other suitable material, preferably of rectangular form, and whose upper surface may, if desired, be provided with a padding B. The purpose of this padding is to provide a'more comfortable rest for the knee of the person using the stretcher; but it may be omitted.

O designates a piece of sheet metal folded or bent to form an upper plate portion 0, which is adjacent to the under side of the block A, and a lower parallelplate portion 0, which is separated from the portion 0 by a space 0'. This 'Inetal piece is secured to the block :A by means of its lateral and end portions, which are bent upwardly and fastened *to the sides and ends of the block, asshown. These upwardly-bent portions orflanges may points. 'tically-separated plate portions is that they Serial No. 701,550. (No model.)

face of the block. This arrangement of the pins is also greatly superior to a construction wherein they are driven vertically through liquely for the reason that in the latter conseats when pressure is brought against the The advantage of the thin-metal veralford a double bearing for the pins, which are thereby held both at the top and intermediate of their length and prevented from bending under strain. This eifect could not be afforded by a single metal plate unless it were thick and heavy, and which I desire toavoid. Moreover, the thin-metal plates are easily perforated, whereas it is difficult and expensive to perforate thick metal. side of the block is firmly secured a screw-eye g, towhich is connected one end of a short chain G, its opposite end heing secured to an eye f near the lower end of a bar or lever F. l-I designates pointed locking-dogs, one at each end portion of the block A. These dogs are formed by rearwardly and downwardly bent end portions or arms of 1a bail-shaped wire or rod K, which extends across the rear portion of the block A and above the same in position to receive the knee of the operator.

At the junction of the arms or dogs H with the lateral arms of the ballK journals or pivot portions are formed, which loosely engage bearings h on the ends of the said block.-

The manner of using the device will be readily understood. The points e are engaged with the carpet to be stretched, the operator In onestretched. By reason of the needle character of the points 0 no injury is done to the carpet. \Vhcn the operator is ready to tack the carpet, he may bring his knee to rest on the rail K, thereby forcing the points of the locking-dogs into engagement with the floor to thereby hold the block and carpet from slipping until the carpet is tacked.

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

1. In a carpet-stretcher of the character described, the parallel vertically-separated thin-metal plate portions on the under side of the block, obliquely-registering perforations in said plate portions, and a plurality of headed pins inserted through said perforations from the upper side, substantially as specified.

'2. In a carpet-stretcher of the character described, the block, the thin sheet-rnetal piece secured thereto, and folded or bent to form the two parallel vertically-separated plate portions at the under side of said block, and a plurality of pins driven or inserted through said plate portions from the upper side, said pins having heads at their upper ends which seat between the upper plate portion and the under side of the block, and at their lower end portions needle-points, which project through the lower plate portion, substantially as specified.

In acarpct-stretchcr, the combination with a block, having upon its under side a plurality of oblique points or teeth, a bar or lever, and a flexible connection between the same, and the said block, of the rearwardlyextended locking-dogs, and the transverselyextending bail pivoted to the block which carries the said dogs, and adapted upon depression thereof to engage same with the carpet, substantially as specified.

4. The herein-described carpet-stretcher, consisting of the knee-block,t11e parallel plate portions at the under side of said block, the oblique pins driven or inserted through the said plate portions, the operating bar or lever, a flexible connection between the same and the block, the rearwardly-extending lockingdogs, and the transversely extending b'ail pivoted to the block which carries the saiddogs, and adapted upon depression thereof to engage same with the carpet, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
