UNETED STATES JACOB S. N AKASHIAN, OF WATERTOWN, MASSACHUSETTS.

PROCESS FOR STRAIGHIENING BUGS.

Application filed August 16, 1926. Serial No. 129,636.

This invention relates to an improved process for straightening or correcting inequalities in the shape of floor rugs, particularly oriental rugs. Many oriental rugs are misshapen in several ways, some of these rugs are shorter on one edge than on the edge which is oppositely disposed thereto; sometimes the difference in length amounting to several inches; they are also curled at the edges, up or down, more or less, so that they will not lie flat upon the floor.

Efforts have been made to overcome these deficiencies and to correct the shape of the rugs so that they will lie flat and have their oppositely disposed edges of the same length. One process for attempting to arrive at this result has been to mark the correct shape and size of the rug on a floor or board and then, by means of hand pliers, to stretch the rug until it assumes the dimensions of the shape thus marked out, the edge of' the rug being tacked to the floor or board, and then thoroughly wetting the rug with water and sometimes with starch.

The result attained by this latter process is merely to straighten the fibers of wool in the rug, and when the rug is again exposed to any dampness, the threads returnto their original shape and the rug again becomes misshapen. This old process also takes a long time for the rug to dry when it is lying in contact with and tacked down to the floor.

The object of this invention is toovercome the difficulties hereinbefore encountered'and to straighten the rug so that it will remain permanently straight and lie flat upon the floor.

The invention therefore consists in the process of straightening a rug hereinafter described and particularly pointed out in the claim.

The preferred form of apparatus for strai htening the rugs by my improved process is illustrated in the accompanying drawin gs in which Figure 1 is a plan view of the apparatus, a rug after having been straightened being shown in dotted lines in connection therewith. i

2 is a front elevation of the said apparatus partly broken away and shown in section. T

Fig. 3 is a plan view of a rug, one edge of which is shorter than the other and illus-, trates one form of misshapen rug which can be straightened by my improved process utilizing the apparatus disclosed in Figs. 1 and 2. I

Like numerals refer to like parts in the several views of the drawings.

In the drawings, 5 and 6 are longitudinal members of the apparatus and 7 and 8 are cross members thereof. The cross member 71s provided with a groove 9 extending longitudinally thereof, in which is positioned a bar 10 which clamps one end of a. rug 11. in the, groove 9, pressure being applied to the barto perform the clamping operation by a usual form .of-C clamp 12 consisting of a frame 13 and screw 14 havinga swivel 15 which bears upon, the clamp bar 10, the end 16 of the frame bearing against the under side of the cross member 7. i

In the drawings there are two of the clamp members shown in connection with the cross member 7, but it is evident that as many of tlfi C clamps may be utilized as may be desira e. i

Brackets 17 are fastened to the underside of the cross member 7, adjacent its opposite ends and are supported by and have screwthreaded engagement with adjusting screws 18 which are rotatably mounted at their opposite ends in brackets 19, two of which are fastened to each of the longitudinal members 5 and 6. Each screw 18 is provided with a handle 20, by which it may be rotated and thus move the cross member 7 toward or away from the cross member 8 in order to stretch the rug is a manner hereinafter more particularly described.

The cross member 8 has pins 21 and 22 adjacent its opposite ends and projecting downwardly therefrom into holes 23 and 24 in the longitudinal members 5 and 6, which are provided with graduations 23' and 24, whereby the cross member 8 can be approximately positioned according to the length of the rug which is to be stretched. The cross member 8 is provided with a clamping bar 25, which is positioned in a groove 26v extending longitudinally of the .cross member 8, which is adapted to clamp one end of the rug 11 in the groove 26 by means of the C clamps 27 which are of the same construction as the C clamps 12.

The misshapen rug illustrated in Fig. 3 embodies a short side 28, an oppositely disposed longer side 29 and ends 30 and 31. The process whereby this rug may be
