SPECIFICATION forming part of Letters Patent No. 767,646, dated August 16, 1904.
Application filed May 19, 1899. Serial No. 717,529. (No specimens.)
T0 all whom, it may concern.'
Beit known that I, IsiDoR Krisnn, of the city and County of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Celluloid, of which the following is a specification.
My invention relates to an improvement in Celluloid.
The object of my invention is to make raw Celluloid plastic in a manner more economical than heretofore practiced.
As is well known, raw Celluloid can only be used for practical purposes if dissolved or made plastic. To accomplish this, the raw material is dissolved in any of the known solvents-such, for instance, as acetone, ether, and alcohol, &c. This processinvolves a great waste of material; and it is the object of my invention to prevent such waste.
Referring to the drawing which illustrates in diagram my invention, A is a tank or receptacle closed at the top with a lid a. This tank is provided with the baskets c a, containing tlie Celluloid a2 a2.
B is a retort provided with the tube b, entering the tank A and terminating in the spraying device b'. The retort is held in position by the adjustable ring c of the bracket C and contains the solvent If. The adjustable burner c is also attached to the bracket and can be connected, through the pipe c2, with a gas-pipe or other suitable source of fuel.
To the upper part of the tank A is Connected the worin d, provided with the condensingreservoir D, placed in the receptacle D and The worm Z is providedI with the check-valve d.
The modus operandi is as follows: The retort B is filled with the solvent b and connected to the tube or pipe at the same time the receptacles i c are filled with the raw celluloidA and the worm d connected with the tank, which is then liermetically closed with the lid a. The fluid in the retort is then heated with the aid of the burner, and as the volatile fluid is evaporated the vapors will enter the tank A and will attack the raw Celluloid contained in the baskets c c, softening the same and making the particles plastic and adhesive. rlhe check-valve cl is attached to the worm d for the purpose that the vapors shall remain in the tank and penetrate the loose Celluloid till a prearranged pressure is attained. The surplus vapor will then enter through the worm the receptacle D and be condensed therein again into a liquid state.
I have illustrated the process as being carried out in a comparative small scale with the aid of retorts and adjustable rings; but other devices may be employed for carrying out my invention. i
The baskets-or receptacles for the Celluloid are preferably made, as shown in the drawing, of wire-gauze.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The process of reclaiming waste pieces or scraps of Celluloid', which consists in subjecting said pieces to the action of fumes or va` pors of a solvent in a closed receptacle until the solvent has permeated the mass and rendered the same sufticien tly plastic for working.
2. The process of reclaiming waste pieces or scraps of Celluloid, which consistsiii subjecting said pieces in a Confined space to the fumes or vapors of a material Capable of acting as a solvent, allowing said fumes or vapors to accumulate until the solvent has permeated the mass and rendered the same suiiiciently plastic for working, and then drawing olil said fumes or vapors.
3. The process of reclaiming waste pieces or scraps of Celluloid, Awhich Consists in placing the pieces in a closed receptacle, subjecting the pieces therein to the fumes or vapors of a material Capable of acting as a solvent until the solvent has permeated the mass and rendered the same suiciently plastic for working, and then drawing ofi' said fumes orvapors.
4. rIhe process of reclaiming waste pieces or scraps of Celluloid, which Consists in placing the pieces in :L Closed receptacle, subjecting the In testimony whereof l sign my name, in the pieces therein to the fumes or vapors of a mw presence of two subscribing' Witnesses, this 22d terial Capable of acting as a. solvent until the day of April, A. D. 1899.
solvent has permeated the mass and rendered ISIDOR KITSEE. the same sufeiently plastic for working, then Witnesses: drawing olf said fumes or vapors, and linally WALLACE B. ELDRIDGE,
condensing said fumes or vapors. EDITH R. STILLEY.
