REUBEN J GRUBB, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO ANDREW COOHRAN, OF SAME PLACE.

ART OF MANUFACTURING CARPETS, RUGS, MATS, 800.

SPECIFICATION forming part of Letters Patent No. 430,230, dated June 17, 1890.

Application filed November 30, 1889. Serial No. 332,141. (No specimens.)

To all whom it may concern:

Be it known that I, REUBEN J. GRUBB, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in the Art of Manufacturing Carpets, Rugs, Mats, &c., which improve ment is fully set forth in the following specification and accompanying drawings.

My invention relates to an improvement in the art of manufacturing carpets, rugs, mats, &c., of the class formed of a body or piece of soft rubber with tufts of yarn passed through the same and appearing on the faces thereof,

producing an attractive, dense, yielding, dur-- able, and superior article of the velvet or pile fabric.

The invention consists of a novel method of producing such carpet, rug, &c.

Figure 1 represents a perspective view of apparatus employed for manufacturinga carpet, rug, or mat in accordance with my invention. Fig. 2 represents a face view of a piece of carpet, rug, or mat made by my method. Fig. 3 represents a section of a portion of the same.

' Similar letters of reference indicate corresponding parts in the three figures.

Referring to the drawings, A designates a number of perforated boards or plates, be tween which are placed sheets B, of soft rubher, so that the latter are sustained by the former, two of the boards or plates being placed between each two of the sheets B. It is obvious that the sheets B may be composed of other material than rubber, all that is requisite being that the foundation sheet shall have capacity for contracting around the'openings or perforations formed therein, as will be hereinafter described, to bind upon the tufts of pile inserted in such openings or perforations.

O designates a series of needles, which are supported in any suitable manner and adapted to be aligned with the rows of openings in the plates, the said needles being connected with mechanism whereby they may be moved in opposite directions through said openings. The needles 0 are held by a reciprocating frame D, having racks E in mesh with order of a gear-wheels F F and G, operated bya crankwheel H on a shaft J.

The operation is as follows: The needles are advanced through the openings of the plates A, and they pierce the sheets B. Yarn.

or thread is then hooked or placed on the heads of the needles, and the latter are returned, so that the yarn or thread is drawn through the openings in the plates, and consequently through the perforations in the sheets B, the Work being continued until the required size of the'goods is obtained, when a knife is passed between the adjacent plates, the yarn or threads being thus cut on opposite sides of the sheets, and the plates are then removed, leaving the yarns or threads projecting in the form of tufts. The plates being now disconnected from the sheets are readily removed, and the tufts are steamed, whereby they swell or expand and form dense and close faces of yarn on opposite sides of the sheets or bodies of the order of velvet or pile fabric, and are prevented from leaving the sheets. The needles are comparatively thicker than the yarn or thread, so that they stretch the portions of the sheet around the openings pierced by the said needles, and consequently when the yarn or thread is drawn through the sheets said portions contract upon or close around the yarn or thread within the sheets, thus tightly holding the tufts and preventing separation of the same from the sheets. This holding action is also assisted by the yarn itself, in that when it is being drawn through the elastic sheets, it is stretched and thinned out. Then when it is at rest it comparatively resumes its normal condition, thus tightening in the holes of the sheet.

By employing yarn or stock of different colors and suitably passing the same through proper openings of the plates fanciful patterns or designs may be produced, a form of which is shown in Fig. 2.

Having thus described my invention, what 9 5 I claim as new, and desire to secure by Letters Patent, is-

1. The method of manufacturing a carpet, rug, mat, &c., consisting in placing a piece of elastic material between perforated supports, 10o

carrying yarn or threads through the said supports and material, and cutting the yarn between the supports, substantially as described.

2. The method of manufacturing a carpet, rug, mat, &c., consisting in passing yarn or thread through a piece of elastic material, cutting the said yarn or thread on opposite sides of the said piece, thereby forming tufts on the faces of the piece, and then steaming the tufts to swell the same, substantially as described.

3. The method of manufacturing a carpet, rug, mat, &c., consisting in supporting a piece of elastic material between perforated supports, piercing said material so as to form openings therein corresponding in position with the perforations in the supports, then passing yarn or thread through the coincident perforations and openings, next cutting the yarn on opposite sides of said material and supports, and thereby producing tufts, and finally steaming the tufts, substantially as and for the purpose set forth.
