FIELD OF T~E I NVENTI ON
This invention relates to the servicing of carpet of the wall-to-wall variety and in particular to apparatus for re-stretching such carpet.
BACKGROUND OF TH~ I NVENTI ON
There are numerous tools used in the laying of wall-to-wall carpet and in subs~quent servicing of that carpet such as in re-stretching. A commonly used device for re-stretching carpets is manufactured by Robsrts Consolidated Industries, Inc. and i6 referred to as the Roberts* Power Re-Stretcher. The present invention is an attachment for use on a carpet stretching or re-; 1;5 stretching deviae such as the Roberts Power Re-Stretcher.
Conventionally, when laying wall-to-wall carpeting a tack strip is secured to the floor and spaced outwardly ; somewhat ~rom ths adjacent wall surfaces. The space between the tack strip and the-wall or baseboard is called a gully. The Roberts deviae referred to hereinafter as the re-stretaher consists of an elonyated frame assembly with a generally L-shaped blade pivotally secured to one end of that frame. 'l'he other end of the frame supports~a head member having carpet gripping ~ inserts on~the~lower sur ace thereof, the~head member being pivotally connected to~a driver whioh in turn is ; similarly connected to the other end of the frame member.

An operating handle is pivotally connected to the upper surface of the frame and also to the driver and the linkage between the handle, the frame, the driver and the head is such that when the handle is moved to a lower position the head with the carpet gripping inserts is moved towards the blade member at the other end of the frame. In a typical carpet laying operation, the blade member of the re-stretcher i6 located in the gully between the tack strip and the base board/wall. The head member with the gripping inserts is pressed in to the upper surface of the carpet preferably to the point where the gripping inserts engage the carpet back. The operating handle is subsequently depressed and the head, moving towards the blade, draws or stretches the carpet towards the wall. With the stretcher so positioned, the -~ operator then uses a knee operated kicker positioned alongside the re-stretcher to move the excess carpet (formed into a slight hump or fold by the operation of the re-stretcher) onto the tack strip with the excess of the carpet curling up the wall to be subsequently trimmed off.
An operator thus proceeds along the length of the wall alternately using the re-stretcher and the kicker.
~; While the above process is effective in laying carpet or re-stretching previously laid carpet, there are some inherent disadvantages. The most important of these is that constant use of kicker~ by carpet layers often results in knee and back problems some of which can : ~ :

operation of the kicker.
SUMMARY OF THE I NVENTI ON
The purpose of the present invention is to provide an attachment in the form of a secondary head which can be secured to the re-stretching device and which i5 located between the existing head on the re-stretcher and the blade member so as to advance the stretch in the carpet from the stretcher head to the tack strip.
Use of the attachment according to the present invention increases the stretch distance and prevents the previous loss of stretch during the process of hooking the carpet onto the tack strip. The carpet is securely and smoothly hooked onto the tack strip insuring a more professional finish that is seldom obtained with the use of a knee kic~er. Moreover, the use of the present invention eliminates numerous tears in carpet and backing sometimes associated with the use of a knee kicker.
It will be appreciated that elimination o~ the use of a knee kicker also will reduce ths occupational health hazards and will bene~it the trade, resulting in fewer claims for workers compensation and insurance.
According to one broad aspect, the invention relatss to a carpet re-stretching device of the type including a frame, blade means on the frame for location in the ~pace between a tack strip and an adjacent wall, a head member with carpet gripping means thereon, driver means interconnecting the head member and the frame and operative means for actuating the driver means to move the head member and carpet gripping means toward the blade. means; the improvsment compri~ing an attachment in the form of a secondary head member with carpet gripping means thereon detachably and operatively connected to ths re-stretching de~ice and located between the first :

DETAILED DESCRIPTION OF THE INVENTTON
Referring to Figure 1, a carpet re-ætretcher is illustrated, specifically a Roberts Power Re-Stretcher : ~ Model 10-107. This device includes an elongated frame 10 having a generally L~shaped blade 12 pivotally secured adjacent one end thereof. As shown, the end of the blade 12 remote from its connection to the frame is adapted to be located in the gully lA between a tack strip 16 and a wall surface or base board 18. The other end of the frame supports a head 20 having carpet gripping inserts 22 detachably secured to the lower end thereof. A driver 24 interconnects the head 20 with an actuating handle 26 through a series of links 28, arms or ears 30 and associated pivot pins 32. The arrangement is such that, ~ 20 when the actuating handle is lowered the linkages cause ; ~ the driver 24 to move the head 20 to the left in Figure 1 towards the blade 12 thereby pulling or stretching the carpet engaged by the gripper inserts 22 towards the blade 12. As can be seen in Figure 1, this leaves a hump or bubble of loose carpet between the head 20 and the blade 12 and, conventionally, this slack in the carpet is subsequently taken up by the use of a knee kicker.
i Figure 2 is a view similar to Figure 1 but illustrates one embodiment of the present invention attached to the re-stretcher. Referring alsa to Figure 3, this embodiment of the present invention consists of a secondary~head 34 of rectangular configuration and substantially of the same dimensions as the primary head 20 on the re-stretcher. A forked arm 36 ~: `;
~ ~ , :: :
~2~Qs~o~
has a pair of spaced ears 38 which are used to pivotally secure the attaohment to the projections 31 on the primary head 20 by virtue of the pivot pin 32 as illustrated.
A somewhat modified arrangement of the attachmsnt i6 shown in Figures 4 and 5 where the head 40 with detachable carpet gripping inserts 42 on the lower end thereof has a pair of extending arms 44 which are adaptad to be pivotally secured to the projection 31 by the pivot pin 32.
Returning to Figure 2, it will be seen that the use of the secondary head advances the stretched portion of the carpet to a point very close to the blade 12 and tack strip 16 so that it is not necessary to use a subsequent knee kicking device.
A further embodiment of the invention is shown in Figure 6 in which the attachment comprises an elongated body 48 having a pair of heads, 50, 52 located one at either end of ths body. This arrangement would be used in place of the primary head 20 on the re-stretcher shown in Figures 1 and 2 and the lower surfaces of the heads 50 and 52 would of course include detachable gripping plates or i~nserts 54.
Figures 7 and 8 show a further embodiment of the invention in which the attachment is of elongated, rectangular configuration, preferably fabricated from light alloy, one end of the attachment comprising a rectangular frame 60 having two halves 62 and 64 adapted to peripherally engage the outer surface of the primary head 20 on the re-stretcher. Suitable attachment means, for example bolts or screws 66 on frame half 62 and captive nuts 68 on frame half 64, may be used to secure the attachment to primary head 20. The attachment also includes parallel, elongated arms 70 extending outwardly ~35 of perimeter frame 60 and supporting at their other ends a secondary head 72 having a detachable carpet gripping insert or plate 74 on the lower end thereof.
: Additionally, a carpet stretch holding plate 76 extends downwaxdly and is spaced slightly outwardly of the forward end of secondary head 72 and, when the plates 76 is pushed down, the handle 26 of the re-stretcher is then released, the plate holding the stretched carpet onto the pins.
While the invention has baen described in connection with a specific embodiment thereof and in a specific use, various modifications thereof will occur to those sXilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
The terms and expressions which have been employed in this specification are used as terms of description and not of limitations, and there is no intention in the ~: use of such terms and expressions to exclude any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
