PROCESS OF MAKING FELT CLOTH.
SPECIFICATION forming part of Letters Patent No. 762,264, dated June '7, 1904i.
Application tiled November 6, 1903.
T0 CLU, whom, it may concern:
, Bc it known that I, PIERRE C. VVARING, a citizen of the United States, residing in Yonke ers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Processes of Making Felt Cloth, of which the following is a specification.
The object of this invention is to provide a process of making felt cloth from stocks differing in quality in a cheap, rapid, and ecovention ,consists of the process of making felt cloth which comprises the steps of forming a web by a continuous and successive deposit of alternate homogeneous stocks differing in quality.
In the accompanying drawings, Figure l represents a vertical longitudinal section of a felt-cloth-forming machine employed for carrying out my improved process of making felt cloth` Fig. 2 is a plan View of the endless apron on which stocks of differing qualities Figs. 3 and 4 are detail transverse sections through' a two-ply and a three-.ply felt cloth made by my .improved process.
Similar letters of reference indicate corresponding parts.
In carrying` out my improved process of making felt cloth any approved construction of felt-machine may be employed. In place of feeding the stock of fur in a continuous bat to the endless apron, from which the same is transferred to the casing in which the perforated cylinder is rotated, the stock is placed on the endless feed-apron in such a manner that at both ends of the Vapron homogeneous bats a a of the superior stock or fleece are placed, while a homogeneous bat b of different stock, lpreferably of poorer quality, is placed on the apron between the two end bats of fleece, as shown in Fig. 2. By thus feeding the stock tothe casing and rotary cylinder a layers is formed. It is obvious that the second bat a of better quality may be omitted, in which case the resulting'cloth is composed of two interfelted layers and presents at one side the appearance of a cloth of the stock of one grade and at the other the appearance of cloth made of the inferior or other grade, or in Serial No. 180,080. (No specimens.)
diate bat of poorer stock on the apron five separate bats can be"`arranged or placed thereon, of which the outer hat and one intermediate bat are of thefbetter stock, while the two intermediate batsv alternating with said bats of better stock are formed of filling-stock. In this way a felt-cloth body of live interfelted layers is obtained; of which two intermediate layers are of filling-stock.
By thus incorporating a layer or layers of filling-stock into the feltfcloth body the same is interfelted with the adjacent layers of lieece without in the least 'impairing the quality of the cloth body, but making even a softer and liner-feeling felt cloth.
Y Having thus described myinvention, I claim as new and desire to secure by Letters Patentl The process herein described of making a felt cloth` which consists in forming a web by'a continuous and successive deposit of lalternate homogeneous stocks diering in qual'- ity, substantially as set forth.
2. The process herein described of making a felt cloth, which consists in continuously subjecting alternately-arranged homogeneous stocks differing in quality to a suction action to interfelt the stocks, substantially as setA forth.
3. The process herein described of making a felt cloth, which consists in alternately arranging hoxnogeneousbats differing in quality, feeding the same continuously, and depositing the stocks by suction to' form an interfelted cloth, substantially as set forth.
4. The process herein described of making PIERRE C. YVARING.
