. UNITED STATES PATENT OFFICE? CHARLES GOODYEAR, OF NEW YORK, N.
IMPROVEMENT lN INDIA-RUBBER FABRICS.
Specification forming part of Letters Patent No. 3,462, dated March 9, 1844.
To all whom it may concern: Be 1t known that I, CHARLES GOODYEAR,
of the city of New York, in the State of New York, have invented a new and useful manner of constructing a machine for manufacturing whatI have denominated Corrugated or Shirred India-Rubber Goods, and I do hereby declare that the following is a full and exactdescription thereof.
I have fully described the nature of what I denominate corrugated or shirred india-rubher goods in a specification thereof intended to constitute an application for Letters Patent therefor, and which it is intended to file'in the Patent Office simultaneously with the present instrument. In that specification I have given the manner in which said goods are manufactured by hand; but the process is greatly facilitated by means of the machine which I am now about to describe.
1n the accompanying drawings, Figure l is a side elevation, and Fig.2 a top view, of a part of my machine, the stretching-frame A A, which may be of great length-say eighty or ninety feet-being represented as cutoff, and showing only its two ends and a part of its middle portion.
B B are two calender-rollers, usually made of metal, between which the two laminae of cloth coated with india-ruoher cement and the stretched narrow strips of india-rubber are to pass. These rollers and others to be described "may he supported on a separate frame, 0 0,
placed at one end of the stretching-frame A A. In Fig. 1 the frame 0 O and its appendages are shown in a vertical section from rout to back through the middle. I) D are two rollers around which the cloth is to he wound, which is to be carried from them over the two rollers B B, and is to pass down between them, embracing the stretched strips or a a of india-rubber between them. b b represent the cloth in its passage from the rollers I) D over those marked B Around the roller B and around a tightening'roller,.E, passes an endless apron, c c c. This endless apron consists of gum-elastic cloth, or of woolen or other yielding material,
its use being to cause the two laminae of cloth which have been coated with india-ruhber ce frame one end of each of the strips a a a is atp tached in such manner as thatsaid strips shall stand parallel to and equidistant from each other. From this sliding frame they are carried over a grooved roller, K, which preserves their parallelism. To stretch the strips a a, strapsL L are attached to the sliding frame I and pass over rollers MM at the rear end of the'machine and down around theends ofthe shaft N, upon which they are wound. By turning the shaft N the narrow strips of india-rubher a amay be stretched to anyrequired extent, and when the shirred goods are being formed the frame I I is allowed to advance toward the calender-rollers'with the samespeed with which the peripheries of those rollers move and carry the cloth from the rollers D D. The corrugated material, as it is formed, may be allowed to descend after leaving the calenderrollers, as shown at O. t
Instead of the foregoin garran gement, I some times form the cross-piece J J of the sliding frame so as toconstitute a grooved roller, and I join the two ends of each of the strips 11 0 together, formingthem each into an endless hand. These strips then pass round the roller J J and round that marked K and under the calender-roller B. l The corrugated cloth, as it passes from the calender-rollers, instead of descendingfas at O, is infthis case conducted round under the calender-roller B to the roller JJ. The distance between the roller JJ and the calender-rollers must under this arrangement be equal to halfthelengthbf the corrugated goods in the stretchcd state. The manufactured article is, when thum'oved from the machine by c ttin g it across. Under this last arrangemenfit e frame II does not approach the calender-rol lprs during. the
made, to be reprocess, the rollers J J merely revolving after the strips upon it have received the proper tension by the action of the straps L L.
Fig. 3 shows a pawl on the shaft N for preserving the tension of the threads a a.
The gearing by which the calender-rollers B B are moved does not differ from such as is generally used fora like purpose. To the construction-of this part of the machine I do not make any claim, nor do 1 claim the use of the calender-rollers,similar rollers having been employed in the manufacturing of india-rubber goods and for other purposes; but
What I do claim as new in the above-described machine, and wish to secure by Letters Patent, is-
or threads their proper tension and allowing them to pass between the laminae of coated cloth or other material, so as to produce the corrugated or shirred goods by an operation of the respective parts, substantially as herein set forth.
