Abstract

An adaptor includes a pair of spaced parallel triangular plates connected together adjacent the apex and sides of the base of the triangle. The plates have registering holes therein adjacent the corners of the apex and sides of the base to receive pivot pins respectively. The apex pin pivotally connects the inner end of a carpet stretcher head pole to the plates with the bases of the triangular plates disposed adjacent to the head, so that the said pole substantially bisects the plates. The remaining pivot pins pivotally connect the inner ends of a pair of extensible buttplate carrying poles to the plates at opposite sides of the carpet stretcher head pole respectively, whereby the adaptor will be prevented from undue turning when stretching pressure is applied by the head against the butt-plates respectively.

CARPET STRETCHER DESCRIPTION OF INVENTION This invention relates to carpet stretchers, and the principal object of the invention is to provide a novel adaptor for use with power carpet stretchers, in the installation of wall-to-wall carpeting, adapted to stretch carpet in long hallways or in rooms in whichone wall comprises sliding glass doors covering the entire wall.

Up to the present power carpet stretchers have comprised a single long extensible pole carrying at one end the stretcher head and at the other end a butt-plate. However, if the room has sliding glass doors covering an entire wall, such carpet stretchers could not be used since the glass would not sustain the stretching pressure. Moreover, if it is desired to stretch carpet along a long hall having staggered doorways temporary planking had to be installed, the planking simulating a wall or back stop for engagement with the butt-plate.

The principal object of my invention is to provide an adaptor for carpet stretchers, the. adaptor being of substantially triangular shape and provided with holes at the apex and side corners thereof, so that the pole carrying the extensible head could be pivoted to the apex ofv the triangular adaptor, the apex being positioned more remote from the stretcher head than the base of the triangular adaptor, so that the stretcher head pole would substantially bisect the adaptor when in use. Additional telescopic poles could be pivotally secured in holes at the sides of the base of the adaptor, with the base of the adaptor disposed substantially parallel with the stretcherhead, the additional poles carrying buttplates which could abut against any fixed wall object such as a door frame or against a wall of the room, to provide a firm abutment for the butt-plates carried by the additional poles.

With my adaptor the two additional poles would thus be used with their butt-plates contacting door frames or walls or other fixed objects in the room or hall, and can therefore be used for carpeting long halls in apartment installations where doors are staggered, one pole of the additional pole pair engaging a fixed object on one side of the hall, and the other pole engaging a fixed object on the opposite side of the hall, each pole being adjusted to the length needed and if necessary using the door frames as back stops for the butt plates when stretching the carpet.

Another object of the invention is to provide an adaptor utilizing two telescopic additional poles that swivel in any direction and can be adjusted to any length to span an opening or glass wall so as to abut against a door frame or the like which is solid and can be used as a back stop for the butt-plates. My adaptor can thus be used regardless of the shape of a room as the two additional'poles can be adjusted to any length in any direction to give support for the stretching head.

A further object of the invention is to provide an adaptor consisting of two triangular pieces of metal, such as aluminum, positioned in spaced parallel relation and secured at the apex and corners by connecting plates welded to the triangular plates.

Still further objects of the invention are to provide an adaptor of the above type in which the pivot for the stretcher head is disposed below, i.e., further away from the stretcher head than are the pivots for the adjustable legs, to prevent twisting or spinning of the adaptor when in use, while permitting the ajustor to assume any desired angle when pressure is applied; also 4 to provide such adaptor with a series of smallholes along the converging sides of the adaptor plate for the purpose of receiving carpet awls or pins so that when stretching from an angle the pins will help keep the adaptor from twisting.

I will explain the invention with reference to the accompanying drawings which illustrate one practical embodiment thereof, to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawings:

FIG. 1 is an assembly view of a power carpet stretcher according to my invention, utilizing my adaptor.

FIG. 2 is a top or bottom plan view of my novel adaptor, detached.

FIG. 3 is a rear perspective view of the adaptor, detached.

FIG. 4 is a front perspective view of the adaptor, detached.

As shown in FIG. 1, my novel adaptor is of substantially triangular shape and consists of identical spaced parallel top and bottom plates la, lb, the adaptor plate being adapted to be placed upon the floor of a room or hallway in which wall-to-wall carpeting is to be stretched, the adaptor overlying said carpet.

Adjacent the apex of the plates la, lb are registering holes 2 in both plates 1a, lb, said holes 2 being adapted to receive pins 3, FIG. 1, or the like, on which the inner end of a stretcher head pole 4 is pivoted, the outer end of stretcher head pole 4 carrying the usual stretcher head 5 which is operable by lever 5a to urge the carpet outwardly away from the adaptor.

It will be noted that the base 10 of the adaptor plate as shown in FIG. 1 lies adjacent the stretcher head 5 so that the pivot pin 3 for pole 4 is further remote from the stretcher head 5 than is the base 1c of the triangular plates la, lb, for the purpose hereinafter described. The pole thus substantially bisects the triangular plates 1a, 1b.

In one corner of the base are registering holes 6 as shown, to receive a pivot pin 7, FIG. 1, which extends through the inner end of an extensible pole 8 so that the pole 8 can pivot with respect to the adaptor, the outer end of the extensible pole 8 carrying a butt-plate 9 which, as shown in FIG. 1, is in firm contact with the base of a wall W in the room to be carpeted.

On the opposite side of the base of the adaptor are registering holes 10 in the plates la, lb of the adaptor adapted to receive a pivot pin 11 on which the inner end of a second extensible leg 12, FIG. 1, is pivoted, the outer end of the leg 12 carrying a butt-plate l3 engaging the lower end of a wall W of the room or hall to be carpeted.

By the above arrangement the extensible legs 8 and 12 may be adjusted with respect to the adaptor to engage any fixed wall, door frame or the like of the room or hall to be carpeted to form a backstop for, the stretcher head pole 4, so that when the stretcher head lever 5a is manipulated on the carpet to be stretched the adaptor will maintain the positionshown in FIG. 1. Since the pivot 3 for the stretcher head pole 4 is further removed from the stretcher head 5 than are the pivots 7 and 11 for the adjustable poles 8 and 12, the adaptor will be maintained against rotation when pressure is applied by the pressure head 5.

in order to further prevent rotation of the adaptor while in use, a series of holes 14 and 15 are provided along the sides of the triangular adaptor, as shown, for the reception of carpet awls or pins passing through the aligned holes 14 and 15 respectively to further prevent twisting or spinning clockwise or counterclockwise of the adaptor when pressure is applied by the stretcher head 5.

I claim:

1. A carpet stretcher comprising an adaptor having a pair of spaced parallel triangular plates connected together adjacent the apex and sides of the base of the triangle; said plates having registering holes therein adjacent the comers at the apex and sides of the base receiving pivot pins respectively, a carpet stretcher head pole having its inner end connected to the apex pin and extending between the plates, with the'bases of the triangular plates disposed adjacent to the head so that the said pole substantially bisects the said plates; and a pair of extensible butt-plate carrying poles having their inner ends connected to the pivot pins respectively disposed at the corners of the sides of the base, and extending between the plates at opposite sides of the carpet stretcher head pole respectively, whereby the adaptor will be prevented from undue turning when stretching pressure is applied by the head against the buttplates respectively.

2. In a carpet stretcher as set forth in claim 1, a series of spaced aligned holes being provided in the plates along the converging sides thereof receiving carpet awls or pins when in use to further prevent turning of the adaptor when pressure is applied.

Claims (2)

1. A carpet stretcher comprising an adaptor having a pair of spaced parallel triangular plates connected together adjacent the apex and sides of the base of the triangle; said plates having registering holes therein adjacent the corners at the apex and sides of the base receiving pivot pins respectively, a carpet stretcher head pole having its inner end connected to the apex pin and extending between the plates, with the bases of the triangular plates disposed adjacent to the head so that the said pole substantially bisects the said plates; and a pair of extensible butt-plate carrying poles having their inner ends connected to the pivot pins respectively disposed at the corners of the sides of the base, and extending between the plates at opposite sides of the carpet stretcher head pole respectively, whereby the adaptor will be prevented from undue turning when stretching pressure is applied by the head against the buttplates respectively.

2. In a carpet stretcher as set forth in claim 1, a series of spaced aligned holes being provided in the plates along the converging sides thereof receiving carpet awls or pins when in use to further prevent turning of the adaptor when pressure is applied.
