JEREMIAH ESSEX, OF NORTH BENNINGTON, VERMONT.

MACHINE FOR DRYING- FIBROUS SUBSTANCES.

To all whom it may concern:

Be it known that I, JEREMIAH ESSEX, of North Bennington, in the county of Bennington and State of Vermont, have invented, made, and applied to use a certain new and useful improvement in machinery for drying cotton-batting, paper hangings, muslins, cloths, and other fibrous substances; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1, is a vertical section of my said invention, and Fig. 2, is an end view o-f the same.

Similar marks of reference denote the same parts.

In the drying of cotton batting considerable inconvenience is found on account of the great length required for the horizontal apron; and if the apron were carried up and down or backward and forward the side of the cotton that had been glazed or sized would be brought into contact with the shafts or rollers under which it passed, causing the cotton to adhere to said roller. The same may be said relatively to the drying of paper hangings, for the surface would be injured by coming in contact with any roller or shaft before the ground color or the printing were dry; and in the drying-of cloths, glazed muslins, &c., the surface is injured by coming against any substance in the process of drying.

To avoid the before mentioned difficulties and expose a large extent of surface of the material to be dried to the operation of heat in a small space, I make use of an endless apron of cloth slats or other articles running up over rollers or cylinders and down beneath drums or pulleys that act only on the edge of the apron, while the fibrous material that is to be dried is laid on or attached to this apron and is moved along on the same, and carried up over the top rollers and down in the bend formed in the apron at the point where the same passes the pulleys that take on the edges of said apron.

In the drawing a, a is a frame of suitable size carrying two or more rollers or cylinders Z), Z9, near the top thereof, over which the endless apron c, passes and is carried up and down the desired number of times and 4returned beneath the machine to the point of beginning.

6l, d, are drums or pulleys near the ends of cross shafts c, e, around which the edges.

of the apron pass at the lowest points of the various leads; and the diierent rollers may be connected together by co-rds or bands as shown so as to relieve the apron of the power necessary to revolve the parts.

When the apron is made of cloth it should have a rope or cord sewed into its edge to travel over the pulleys CZ, d, and rollers b, b, which should 'be grooved at this point to keep the apron in position widthwise of the machine.

f is a roller which may be adjustable to keep the necessary tension on the apron, and near this point the batting or other fibrous material is laid onto the apron and travels therewith, up and down, and its surface is untouched by any substance until dry.

In those cases where the shrinkage of the material in drying such as with paper hangings, would be liable to bring the surface in contact with .the cross shafts e, c, they may be dispensed with and the pulleys d, d, set on short studs or gudgeons. And where the length of material to be dried and the time necessary for the purpose, would render one single apron inconvenient to keep in order on account of its length, two or more aprons may be used, the material that is being dried passing from the top roller of one, to that adjoining, of the next apron.

To wind up the batting cloth or other material I provide a roller g in bearings h, 7L, beneath which is a friction reel z', rotated in the right direction by the belt 7c, and the ends of the roller g rest on the heads of reel i, so that said roller g is revolved by friction from the heads (i, 21,) and if the weight of the roller g be such that the friction will wind the paper with the necessary tension, the roll will continue to be wound with about the same tension as it increases in size, in consequence of the increased weight on the shaft of the roller, producing more.V

friction. Having thus described the nature and operation of my said invention I wish it to be understood that I do not claim an endless Y vious instance in which an apron has been by the pulleys d, d, or their equivalents so guided by pulleys or their `equivalents at acting on the edges only of said endless the lower portions of `their folds acting at apron in the manner and for the purposes the edges only of such apron,V that the Whole specified. 15
