Letters Patent No. 80,809, dated August 11, 1868.

IMPROVEMENT IN THE MANUFACTURE OF RUBBER AND OTHER COATED CLOTH AND FABRICS.

tits 5:11am: mantis in tight Zt'ttttrs fitttut rut mating and at the same.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY CQME:

Be it known that we, JOHN W. COBB, of Melrose, in the county of Middlesex, and EDWIN A. HILL, of Quincy, in the county of Norfolk, and State of Massachusetts, have inventeda new and useful Machine for Coating Cloth with a Vnlcanizable Material, such as caoutchouc or compositions of India. rubber or gutta pcrcha, and vnlcanizing the coating; and we do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view, and

Figure 2 a vertical section of the'said machine.

In such drawing, A is the main cylinder of the machine, such cylinder being chambered, and having a passage, or, leading through one of its journals. Such passage is to enable steam to be introduced into the interior of the cylinder, for the purpose of heatingit to a vulcanizing-temperature, The .said cylinder is.

arrangedwithin a frame, B, and has its journals supported in boxes in such frame, there being a gear-wheel on each of such journals. One of these'gears, viz, C, engages with a pinion, D, fixed on the shaft of another but smaller hollow cylinder E, arranged in front of the main cylinder, and having a diameter somewhat greater than that of the said pinion. The cylinder E is also to be heated by steam let into it.

The other gear, viz, F, of the main cylinder, engages with a pinion, G, fixed on the journal of another hollow cylinder H, arranged below the cylinder E, and close to the cylinder A. The cylinder H should also have means for allowingsteam to pass into it for heating it.

Above the cylinder A, is a roller, I, andthere extends from such roller around the cylinder A, and nearly to the cylinder H, a hollowjacket or case, K, divided by a partition, 19, into two shallow chambers q r. When the machine is at work, steam is to be let into the inner of the said chambers, the outer one being to containair, and therewith operate as a means of preventing condensation of the steam by the external atmosphere.

The boxes of the cylinders E H are to be provided with adjusting-screws, by which the distance of the said cylinders from the main cylinder A may be either increased or diminished, as circumstances may require. The outer curved surface of the cylinder E is to move faster than that of the cylinder .A,in order to grind the rubber or caoutchouc between the two surfaces, and lay or spread Zit'onthe main cylinder, it being laid in the space between thetwo. v

The sheet of cloth is to be run in upon the cylinder- H, and thence between the cylinder A and its encomi it goes between the cylinder A and-the guide-roller I, and thence passing steam-jacket or case K, after whicl upward. O The cylinder H operates to press the cloth in contact with the rubber spread on the cylinder. It also heats such cloth and the rubber, and aids in effecting the vulcanization of the latter, which will be completed by the cylinder A and'its stehm-jacket. v

We are aware that in machines for spreading rubber on cloth, it has been customary to warm the rollers by steam let into them, the temperature employed never having been sufiicient to efi'ect what is termed vulcanizing the rubber or caoutchouc composition, the vuloanizing of which has always afterward being cfiectedby a different means What we claim as our invention, is O The combination of mechanism for spreading rubber or a vulcanizable material on a surface or cylinder,

nd applying the coating to cloth, in manner as set forth, with mechanism for vulcanizing the coating of rubber or vulcanizable material, while it with the cloth may be passing about the surface or cylinder on which the rubber or said material may be spread.

We also claim the combination and arrangement of the steam-jacket or heater K, with the steam-heating cylinder A, and the twocylinders E H, arranged and connectedso as to operate as and for the purposes specified. We also claim the combination and arrangement of the air-protective space 2-, the steam-chamber q, and

the steam-cylinders A E H, arranged and connected, so as to operate substantially in manner and for the pur: poses-as specified. v

We also claim our process of applying rubber or caoutchouc or a vulcanizable'material to cloth, and vuleanizing such rubber or material after such application of it, the same consisting in spreading the rubber or yulcanizabl-e material on a cylinder, and forcing a sheet of cloth in contact with the coating so spread,'and vulcanizing it while on the cloth, and while the latterwith the rubber or vulcanizable material may be passed about the cylinder, such -vuleanizing of the rubber or its equivalent being effected by heat applied to the cylinder or cylinders used in the process of spreading the rubber, as set forth, or to them and a steam-jacket, as described. I v

We also claim the process of making a sheet of rubber or vulcanizable material, and vulcanizing it, the

samecon'sisting in spreading the rubber or material ona cylinder by means as described, and vul'canizingthe rubber while on such cylinder by heat produced therein, by mearis of steam let into it, as set forth, or into it, and a steam-jacket arranged with it, as specified. I v
