DELaw, A conrona'rrom' PROCESS 01E' PEODUCING RTIFIGIL LEATHER.
To all 'whom it may concern.'
Be it known that I, THoMAs J TURNER, of Wilmington, in the county of New Castle, and in the State of Delaware, have invented a certain new anduseful Improvement in Processes of Producing Artificial Leather, and do hereby declare that the following is a full, clear, and exact descrip# tion thereof.
i methods of producing artificial leather by the use of nitrocellulose compositions.
The object of my invention is to provide a process Ofthis character in which the nitrocellulosecomposition may be applied to the fabric in a convenient and rapid manner. A further to provide a process of this character in which old nitrocellulose compositions may be used in th be reworked. This enables scrap Celluloid to e production of the artificial leatherin accordance with my invention.
While my invention is capable of embodi- 'ment in many different forms, for the purposes of illustration I shall describe only one form thereof herein. Furthermore, for the purpose of illustration, I shall describe only one form of apparatus in which my invention may be carried out, in the :accompanying drawings, in which Figure 1 is a front elevation of a machine which may be used in connection with my process;
Fig. 2 is a side elevation of the same;
Fig. 3 is an end elevation in detail of a sha 1 on which the fabric is carried when being fed into the machine;
Fig. 4 is an end elevation of one of the wooden shuttles used for carrying the fabric; and
,Fig 5 is an end elevation of one of the gears.
In the drawings I have shown a machine having a main frame 1, in which there are carried three rolls 2, 3, and 4. These rolls 2, 3 and 4 are carried upon shafts 5, 6 and 7, respectively.` The shaft 6 of the middle roll 3 isv maintained in a fixed position in the main frame 1. The shafts 5 and 7, however, are supported in vertically movable boxes 8 and 9, which are\adapte to be adjustedl b v means of screws 10 and 11, supported in .the main frame 1 and having Specification of Letters Patent.
invention relates particularly to object of my invention is,
Patented JV 111ml@ lill, 11918.. Renewed December 19, 1917. Serial No. 207,879.
' Worm wheels l2 and 13 on their ends which mesh with worms 1'4 and 15, carried by two -shafts 16 and 17, and adapted to be operated yby handles 18 and 19. The shafts 5, '6 land carry near one end thereof, gears 20, 21 and 22, which are keyed tothe shaft by means of removablekeys 23, said gears 20, 21 and 22 being all of the same size. Upon the other end of the said shafts 5, 6 and 7, areV carried gear-S124, 25 and 26, the gear 25 being smaller than the gears 24 and 26, v and said gears being keyed to their respective shaftsin a similar `manner to the gears 20, 21 and 22. Only one of these sets of gears is use d -at a given time. When the gears 20, 2l and 22 are used the keys are removed from gears 24 and 26, and when the gears 24, 25 and 26 are used the keys are removed from the gears and 2,2. The gears 20, 21 and 22 are used when it is dethe same speed, and the gears 24, and 26 are used when it is desired to have the top and bottom rolls move slower than the middle roll. The central shaft'6 is extended at the one end of the machine so as to carry a large gear 27, which meshes with a small gear 28 having at one end thereof a tight pulley 29 and a loose pulley 30. Guide 'plates 31 and 32 are supported upon rods 3-3 and 34 from themain frame 1, said guide plates 31 and 32 fitting against the adjacent faces of the rolls 2 and 3 to retain a body. of plastic material 35 in place thereon. Near the bottom of the main frame 1 supports ina pair of arms 36 a shaft 37 adapted to receive a wooden bobbin 38 carrying a roll of fabric such as cloth to be provided with a coating. J A friction band 39 extends around the shaft 37, so as to retard the unwinding of the 'fabricand therefore maintain it taut. From the shaft 37, the fabric is fed over a guide roll 40, supported in the arms 36. From thisoint the fabric passes between the rolls 3 an 4, where it receives a coating of plastic material from the body of plastic material 35 on top of the fabric. 'After passing lbesired to have the rolls 2, 3 and 4 move at l -tween the rolls, the coated fabric may be conveyed away and the dr and harden..
n thev operation of my invention with the machine above described, the coating of plastic nitrocellulose composition, containcoating allowed to i l ing al latent solvent such as camphor, or
"some camphor substitute, is applied to the upper ,surface of the fabric being fed through the machine. 'llhe plastic composition'to be applied may advantageously be of the following composition Nitrocellulose 16% Camphor' 4% Pigment 5% Volatile solvent 40% oilf 35% After mixing these constituents to ay uniform plastic mass the solventis evaporated until the composition reaches the proper consistency to apply to the rolls .above referred to. l
The volatile solvent may be any of the I following: Ethyl alcohol, benzol, ethyl acetate, acetone, methyl acetone, etc., and the oil used is preferably castor oil,'although other .oils may be used instead.
The pressure of the rolls anchors the plastic material permanently tothe fabric y forcing the plastic composition into the' interstices of fabric. After the coating has incassa from the spirit of. my ina coating of a nitrocellulose plastic by means.
