One hundred and twelfth, to Charles F. Crockett, June 17, 1856. For improvement in making sheets of leather from curriers’ shavings or buffings.
The inventor says: “I do not wish to confine myself to any particular kind of cement, although I found India-rubber cement to answer the best purpose. Curriers’ glass is a good instrument to press the edges together.”
Claim.—Making sheets of leather of any desired size and thickness of curriers’ shavings or buffings, by lapping and cementing them together while in a moist state, and then subjecting the mass to pressure.
One hundred and thirteenth, to Nathaniel Hayward, Colchester, Ct., April 15, 1856. For improvement in the manufacture of India-rubber.
One hundred and fourteenth, to Nathaniel Hayward, Colchester, Ct., May 6, 1856. For process of preparing elastic India-rubber cloth.
Claim.—The producing an elastic fabric of uniform strength by uniting a sheet of rubber with sheets of cloth thinly coated on one side with a vulcanized compound of rubber; the sheet of rubber before it is united with the sheets of cloth being in the modes set forth so prepared that the central part of it is completely vulcanized, while the surfaces are not.
One hundred and fifteenth, to A. D. Puffer, Somerville, Mass., May 20, 1856. For improvement in lining metal pipes with gutta-percha.
One hundred and sixteenth, to James Reynolds, New York, June 16, 1856. For improvement in Mandrels for making gutta-percha tubing.
One hundred and seventeenth, to Austin G. Day, Seymour, Ct., June 10, 1856. For improvement in cleaning India-rubber.
One hundred and eighteenth, to James Reynolds, New York, June 10, 1856. For improvement in feed apparatus for working gutta-percha.
One hundred and nineteenth, to James Reynolds, New York, July 29, 1856. For improvement in gutta-percha apparatus for covering wire.
One hundred and twentieth, to William F. Shaw, Boston, Mass., August 12, 1856. For improvement in treating India-rubber.
One hundred and twenty-first, to Jacob H. Howell, Ansonia, Ct., Oct. 21, 1856. For improvement in making India-rubber hose.
One hundred and twenty-second, to Henry Forstrick, Hoboken, New York, Oct. 28, 1856. For improvement in working over vulcanized India-rubber.
One hundred and twenty-third, to Nathaniel Hayward, Nov. 4, 1856. For improved catch for India-rubber shoes.
Claim.—The use of a steel rubber or other kind of spring catch of any proper shape, in the heel of an India-rubber over shoe or clog, having a projection or lip extending out horizontally or through the quarter as specified, whereby the over shoe is prevented from slipping at the heel, and is susceptible of being disengaged from the under boot or shoe without using the hands.
One hundred and twenty-fourth, to T. Gault, Seymour, Ct., Nov. 11, 1856. For process of cleaning India-rubber.
One hundred and twenty-fifth, to Henry Davenport, New York, Dec. 23, 1856. For improvement in machines for cutting India-rubber threads.
One hundred and twenty-sixth, to James Reynolds, New York, Dec. 9, 1856. For mode of making gutta-percha cord.
One hundred and twenty-seventh, to Charles Goodyear, of New Haven, Conn., June 15, 1844. Re-issued December 25, 1849, in two separate patents, being Nos. 156 and 157 of re-issued Patents, viz. For India-rubber fabrics.
No. 156.Processes for the manufacture of India-rubber.I claim the curing of caoutchouc or India-rubber by subjecting it to the action of a high degree of artificial heat, substantially as described and for the purpose specified.
And I also claim the preparing and curing the compound of India-rubber, sulphur, and a carbonate of other salt or oxyd of lead by subjecting the same to the action of artificial heat, substantially as described.
No. 157.Felting India-rubber with Cotton Fibre.I claim incorporating the fibres of cotton or other substance with India-rubber by preparing the fibres of a fleece or bat of cotton or other fibrous substance into a sheet of India-rubber in the green state, without subjecting the fibres, after they have been incorporated to a stretching or drawing operation, substantially as described.
One hundred and twenty-eighth, to James Reynolds, of New York City. For Machine for making gutta-percha pipes and covering telegraph wires.
This invention is for the purpose of forming, tubing, or coating wires—both operations being substantially alike—by forcing the gutta-percha, while rendered plastic by heat, through a die. The necessary pressure for this purpose is applied by a piston workingin a cylinder, in which the material is placed and kept heated, or by other suitable forcing apparatus.
One improvement consists in connecting the cylinder with an air pump, or other suitable exhausting apparatus, whereby any air remaining in the said cylinder after it has been filled as full as possible with gutta-percha and closed, may be extracted before applying the pressure. The manufactured article is thus rendered free from blow holes, and is perfectly firm. This is a result of great importance for small tubing and the covering of fine wire.
A second improvement consists in arranging the die and core by which the tube is produced or the covering of the wire performed, in a position transverse to the direction in which the piston works to produce the pressure, to allow a hollow core to be used for the admission of air into the tube as fast as it is formed, and also to prevent it from collapsing by the formation of a vacuum within. The same arrangement also permits the passage of the wire through the die when it is being covered by the percha.
A third improvement consists in providing the stomach in which the die is placed, with an opening, to allow of the constant escape of a certain quantity of material during the operation. By this means the quality of the manufactured article is rendered more uniform. Without such an arrangement it is almost impossible to produce small tubing or cover fine wire with any degree of uniformity of thickness.
A fourth improvement consists in the employment of a continuously revolving trough of water, suitably arranged to receive the tube or covered wire as fastas it leaves the die, and coil it up in the water to cool it, to prevent the coils from sticking together.
One hundred and twenty-ninth, to Thomas C. Wales, of Dorchester, Mass., February 2, 1858. For Water-proof Gaiter Shoes and Boots.
I do not claim the vulcanizing process, nor do I claim making articles of cloth cemented together with rubber cement and afterwards vulcanizing them, nor do I claim making shoes partly of leather and partly of cloth, the same being made by connecting the leather and cloth together by water proof caoutchouc cement, as such when made partly of leather cannot be vulcanized, owing to the fact that the great heat required in the vulcanizing process, injures or destroys the leather.
I claim a new or improved manufacture, or water-proof vulcanized rubber and cloth gaiter shoe, made in manner and with its external layer of cloth, and its lining of cloth arranged together, and with respect to the remainder or rubber parts or foxing, substantially as specified.
One hundred and thirtieth, to Edwin M. Chaffee, of Providence, R. I., February 26, 1858. For India-rubber Door Mat.
I do not intend to confine myself to the lozenge cells, as it is obvious that square and some other forms will do as well.
Neither do I intend to confine myself to ribs or ridges intersecting each other, as it is evident that ridges forming various figures will answer much the same purpose, such, for instance, as run circular, parallel,serpentine, zig-zag or angular, or any other raised surface of rubber.
Nor do I confine myself to rubber alone as the only gum, as gutta-percha, and other gums may be substituted for it.
I claim the mat as formed by ridges or grating, together with the cells or spaces, of whatever form, the one to serve as scrapers to clean the foot, and the other to contain the dirt, whether of rubber, gutta-percha, or other flexible gums.
One hundred and thirty-first, to Gustavus Cuppers, of College Point, N. Y., July 20, 1858. For manufacture of Hard Rubber Goods.
I wish to have it distinctly understood that I do not claim as my invention the heating or curing process, as it is called, nor the combination of India-rubber and gutta-percha with sulphur, nor any other combination already patented and described.
But I claim the improvement in the hardening or curing process of caoutchouc or India-rubber and of gutta-percha, by which articles, wares, goods and merchandize may be manufactured into any desired size, form or shape, substantially as described.
One hundred and thirty-second, to Abraham Brower, of New York City, July, 1858. For Water-proof Cement.
I am aware that water-proof compositions for leather consisting of tallow, suet, wax, rosin, tar, oil, and India-rubber have been employed; these I do not claim of themselves, singly or combined.
I am not aware, however, of shellac or glue everhaving been employed in unctuous water-proof compositions for leather; but these I do not claim of themselves in my composition, apart from the other ingredients, as all are required combined, to render it so excellent for the purposes set forth.
What I claim is, the composition composed of all the ingredients described, and in about the proportions for the purpose set forth, the same constituting an improved new and useful article of manufacture.
By a judicious compound of tallow, bees-wax, resin, shellac and glue, the inventor produces a very superior water-proof composition, the leather remains soft and pliable, will take a polish, and repel water very perfectly.
One hundred and thirty-third, to Austin G. Day, of Seymour, Conn., August 10, 1858. For treatment of caoutchouc.
I do not claim in the broad, vulcanizing rubber or equivalent gums, and irrespective of the special process used and product made. Therefore—
What I claim is, running the heat for vulcanizing elastic hard rubber compounds as set forth through the several grades of temperature, and the several intervals of time described and illustrated in the specification.
I also claim making, as described, the elastic, hard rubber composition of two parts by weight of rubber, and one part of sulphur, when such composition is made preparatory to the running of the heat through the several grades of time and temperature as set forth in the specification.
I also claim equalizing the temperature in the heating apparatus by mechanical means or by a current of steam, or its equivalent, in the manner set forth.
One hundred and thirty-fourth, to Samuel Whitmarsh, of Northampton, Mass. For Composition for Artificial Leather.
I do not claim, broadly, the saturation of cloth and other fabrics in linseed oil containing umber or other substances.
But what I claim is the fabric specified, composed of cotton or other fibrous substance, in a woven or unwoven condition, saturated or coated with a compound of linseed oil and burnt umber that has been prepared as described.
Samuel Whitmarsh, of Northampton, Mass., has invented a new fabric which is intended to supply the place of leather in many of its applications. The fabric is composed of cotton or other fibrous substances either woven into cloth or in an unwoven state, and saturated or coated with a compound of linseed oil and burnt umber, prepared by boiling in every gallon of oil about three pounds of umber in a powdered state, for such a length of time, that the composition when cool will roll in the hands without sticking. The fabric may be made in forms suitable for the soles of boots and shoes, coverings for trunks, traveling bags, cap fronts, or as a substitute for carriage or harness leather, or for machine belting or hose pipe.
The mode of producing the fabric differs to some extent according to the use for which it is designed, but the general principles are in all cases the same.The umber is stirred into the boiled oil until it reaches the point desired, when it is ready to be applied in the manner best calculated to produce special articles.
One hundred and thirty-fifth, to O. S. Boyden, and M. C. Fredericks, of Newark, N. J. For Composition for varnishing leather.
We claim the employment in the compounds used in the manufacture of glazed, japanned, or painted leather, cloth, silk, and paper—either wholly or in part as a substitute for camphene or spirits of turpentine—of a paste made of the glutinous properties of flax seed, substantially as and for the purposes set forth.
The compounds commonly employed for the first, or first and second coats, in the manufacture of glazed or japanned leather or cloth, is made by boiling a certain quantity of umber in linseed oil, and adding a quantity of lampblack or other coloring matter with a quantity of camphene or spirits of turpentine, about equal to one and a half times that of the linseed oil. O. S. Boyden, and M. C. Fredericks, of Newark, N. J. have invented an improvement on the above composition, which consists in the substitution either wholly or in part for the camphene or spirits of turpentine in the compound, of a paste made by boiling flaxseed, either whole or after the oil has been expressed, and either ground into meal or unground, in water till its glutinous property is extracted. The use of this paste as a substitute for camphene and spirits of turpentine not only reduces the cost of the compound,but also renders the goods more pliable, and less likely to crack.
One hundred and thirty-sixth, to Francis Baschnagel, of Beverly, Mass., assignor to the Beverly Rubber Company. For restoring waste vulcanized rubber.
I claim the application of heat from 150° to 600° Fahrenheit, to waste vulcanized rubber with or without immersing it in cold water or any other cooling fluid as specified for the purpose of restoring the same, so that it may be used again in the manufacture of India-rubber goods and substances, hereby expressly disclaiming all and every right to the application of artificial heat to new rubber, vulcanized or not vulcanized, and to the application of heat to rubber in any manner and for any purpose except as above set forth.
