CARL BRUNO DOLGE, OF DOLGEVILLE, ASSIGNOR TO ALFRED DOLGE, OF

' NEWV YORK, N. Y.

METHOD OF PRODUCING FELTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 314,809, dated March 31, 1885.

Application filed December 11, 1854. (No mode.)

To all whom it may concern:

Be it known that I, CARL BRUNO DOLGE, a citizen of the United States, residing at Dolgeville, in the county of Herkimer and State of New York, have invented new and useful Improvements in Methods of and Apparatus for Producing Felted Fabrics, of which the following is a specification.

This invention relates to a new and improved method of producing felted fabrics, as hereinafter more fully described.

The accompanying drawing represents a side view of the apparatus which I use in car rying out my invention.

In the drawing, the letters A A designate two wool-carding machines of the well-known construction, and the letter B designates a feltingmachine.

The carding-machines are placed upon a platform or floor, beneath which is placed the felting-machine, so that the webs discharged from the carding-machines can be conveniently carried by means of an endless apron, 0, down to the felting -machine. The wool or other material to be felted is fed to the carding-machines over the feed-tables a a, and the webs produced by the carding-machines are taken off from the doffers b b by doffing-combs c c, and then they are conducted simultaneously to the endless apron O, which carries both together to the felting-machine, the two webs being indicated by dotted lines in the drawing. After the two webs leave the endless apron 0, they are carried by two aprons, d 6, through the felting-machine B. The apron 0 passes round a roller, e, thence through between the felting-rollers, and over a series of supporting-rollers, (1 The apron d passes over a series of top rollers, d, under a roller, dithrough between the felting-rollers over the apron e, thence over the supporting-rollers d beneath the apron e, thence round rollers d d to the top roller, (1. The two webs coming down from the carding-machines are carried through the felting-machine between the two apronsd e, which carry the same along over the supporting-rollers d and as the two aprons separate beneath the roller 0 the webs are lifted from the apron (Z by a workman or by automatic means, so that they follow the apron e, and are caused to pass again and again through between the felting-rollers. The

movement of the carding-machines and of the apron O is so timed that when the webs first formed have passed through the felting-machine, and before they enter between the felting-rollers for the second time, one or more webs are carried down by the apron O and caused to pass through the felting-machine simultaneously with the two webs already felted, and so on, so that the webs first formed are felted together before any new webs have been added. Then one or more webs are added and felted together with the two webs previously felted, and so on until the fabric has attained the required thickness.

In the felting process as usually practiced webs are formed on drums connected with cardingmachines, and then a large number of them are placed one on the top of the other until a pile is formed of sufficient thickness, and this pile is passed through a felting-machine or exposed to a felting action. In following this process the extreme layers near the top and bottom of the pile become thoroughly felted together; but the middle layers of the piles are not sufficiently felted, and the felted fabric thus produced is liable to split apart throughout its entire length and width. In following my method of felting all the layers become thoroughly felted together, and the felted fabric made according to my invention is of equal strength and firmness throughout, so that no portionof the same is liable to scale off. It must be remarked that in the method above described the webs are formed and felted together in pairs; but, if desired, one of the carding machines may be stopped after the first pair of webs has been formed, so that the successive webs are felted together singly with the webs already felted.

It will also be noticed that in carrying out my invention the successive webs are formed while the webs previously formed are being exposed to a felting action, so that the operations of felting and forming the webs go on without interruption until the fabric has reached the desired thickness.

The felting-machine B, which I have illustrated in the drawing, forms no part of my ICQ present invention, and it consists, principally, of a series of steam-heated rollers, b, and of a series of top rollers, 12 The rollers b receive a positive revolving motion in the same direction and of the same superficial velocity as the aprons d e, while the top rollers bear down upon the aprons by their own gravity, and receive a short and rapid reciprocating motion in the direction of their length.

I do not here claim the apparatus shown and described for carrying my method into effect, as such will constitute the subjectmatter of a separate application for Letters Patent.

What I claim as new, and desire to secure by Letters Patent, is

1. As an improvement in the art of felting, the method substantially as herein described, which consists in taking two webs and exposing them to a felting action, then adding one or more additional Webs and exposing them, together with the webs already felted, to a felting action,and so on until the fabric has reached the required thickness.

2. As an improvement in the art of felting, the method substantially as herein described, which consists in forming two webs, and While these webs are exposed to a felting action CARL BRUNO DOLGE. n s.]
