Specification of Letters Patent.

.. Patented Mar. id, 1916.

Application filed .Tuly 20, 1915. Serial No. 40,815.

I To all whom it may concern Be it known that I, GEORGE S. Cox, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Haircloth Fabric andProcesses ofM'aking Same, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, which form a part of this specification.

Probably the only objection to the employment of haincloth as a stiffener for cloth ing is the tendencyof the individual hairs to work out of the fabric and project through the garment. These projecting endsof,

hair-cloth are unsightly as well as unpleas ant to the touch, and the wearer of the garmentusually pulls out the lengths of, hair whose ends project. -While this results often in substantial loss of stifiness, the main objection' is usually the oifense to touch and sight before mentioned.

The main object of the invention is to so treat the fabric as to eliminate any tendency of the hairs to work out and at the'same time not deleteriously adect either the desired stiffness or flexibility of the hair-cloth.

Another object of the invention is to improve, in general, the appearance, quality and efiiciency of the cloth.

The invention is applicable either to cloth view of my improved fabric after treatment. y

It will be understood that my process is not dependent for its execution upon any particular mechanism and indeed may be carried out, less economically, by hand. It

may also be stated that while thefinished product is capable of fairly accurate de-' scription, it can -be illustrated only with some approximationto' the actual condition,

and Fig- 2. isto be'considered, therefore, as to a certain extent an ideal or picture.

Th .ii. hair-cloth fabric, which I.

have elected-to use as an illustration of a fabric to which the invention may be applied, consists of a plain up and -down weave 1n which the warp threads 31 7 are oI cotton and the weft 2 of hair, there being one pick of halr in each shed of warp. This fabric, after it is woven, is caused to travel through a bath of rubber cement. While I prefer to employ rubber cement, the inventlon is not limited to the employment of any partlcular composition, and the term cement where hereinafter used, is intended to include any substance which is capable of being substituted for the rubber cement and which will act in a similar manner. The receptacle a. for cement is shown at the left-hand end'of Fig. 1.

b, b, 6 represent guide rollers for directiisngl the cloth into and through the recepac e.

When the cloth emerges from the bath it isjcoated with the cement, which, however,

- has not, perhaps, thoroughly yet permeated the interstices of the fabric; and furthermore, an excess of cement is carried-by the fabric.

through a drier e, which reduces the soft ness and stickiness of the cement, whence the fabric is led through one or, more pairs of rdlls f, f, which have a further consolidating action upon the cement, The operation' need not be a continuous one, and I- have indicated this lack of continuity by illustrating "the fabric in dotted lines between the rolls f and f; it being understood that, at this point-in the process, the fabric maybe removed and allowed to dry' under natural or artificial conditions for any not too prolonged length of time. By

means of guide rolls g, g, the fabric is then fed, preferably in an upward direction, between a pair of brushes h. These brushes are located immediately below hoppers i, which contain powdered talc, soapstone, sulfur or any other ingredient, preferably in powdered form, that will perform the same function. The brushes It rotate in a direc- The fabric 'is therefore passed througha pair of rolls 0, --which may be tion opposite to that of the travel of the cloth and serve to cover the cementitious surface of the cloth with a thin coating of the powder. Beyondthe upper guide roll 9 the brushes pass between a pair of calender rolls j, whlch serve to press the powder into the body of cement near its surface and finish and hardensuch surface. Beyond the calendar rolls 7' the cloth passes between apair of brushes m, which, like brushes'h, rotate oppositely. to the direction of travel of the rolls. These brushes remove the loose excess of powder remaining on the surface of the cloth. Rolls 11., n, are merely feed -rolls which draw the fabric through the coating mechanism described. .The treatment of phe hair-cloth is then practically 'clothimpregnatedwith a cementitious substance and a powdered solid substance superficially consolidatedwith the cemencompleted, although it may be further dried.

In place of dusting the cement-impregnated cloth, with powder it may! be -coated with a liquid veneer as, for example, starch and water, butthe product is notquite: so

satisfactory.

The result of the described treatment is to produce the fabric diagrammatically illustrated in Fig. 2, in whichthe weave is permeated,- more or less completely, by a cementitious substance having "a comparatively hard, smooth, thinsurface w and a comparatively soft yielding interior w. The comparatively soft interior insures the desired maintenance ofthe' flexibility of the cloth and bindsthe hairssecurelyin posi tion while the hard smooth surface prevents any superficial stickiness and maintains the interior in the relatively soft condition best adapted to'hold the hairs from longitudinal movement. Y v

In using the term hair-cloth in the claims I desire itto be understood as .comprising the ordinary hair-cloth of commerce or any variations thereof present ing, when untreated, the conditions which it is the purpose of my invention to elinilnate.
