FIRE INSULATOR AND EXTlNGUlSHER- Specification of Letters Patent.

Patented Feb. 13, .1906.

Application filed April 12,1905. Serial No. 255,188

To all whom, it many concern.-

Be it known that I, ORVILLE T. Wnrsnn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Fire Insulators and Extinguishers, of which the following is a specification.

This invention is a fire insulator and extinguisher designed particularly for use in connection with photographic lms. Its leading purpose is to prevent the combustion of films used in moving-picture machines, which. are commonly made of celluloid, and owing to the combustiblenature of this material their unprotected use is a source of considerable danger, especially where they are used in projecting-machines in close proximity to a ight. My invention is designed to incase the reels on which the films are Wound in fireproof casings having automatic cut-off mechanisms which extinguish the burning film without the casing.

In the'accompanying drawings, Figure 1 is a side elevation of an apparatus embodying my invention, the lid.of the casing being broken away to show the interior construction.v Fig. 2 is a vertical longitudinal sectional view taken through the extinguishing ap aratus and the part of the casing to which it is connected, and Fig. 3 is a plan view of the mechanism shown in section'in Fig. 2.

The apparatus comprises the fireproof casing 1, having the lid 2 connected therewith by the hinge 3 and the s ring-catch 4, the joints being made practical y air-tight. Within the casing are secured the housings 5, connected by the web 6, which is fastened to the casing by the screws 7. The housings have journaled therein the

rollers

8 and 9, the latter having 'ournals 9 working in vertical slots 10 of the ousings. broad plate 11, extending between the housings, is fulcrumed u on a rod or bearing 12, and secured to this p ate in close roximity to the housings are the vertical p ates 13, havin the inclined edges 13 the latter engaging t e journals 9 A counterweight 14 is secured to the fulcrurned plate or lever 11 to counterbalance the roller 9, supported by the plates 13 and lift it into engagement with the roller 8. guard 15 is supported by} the web 6 and extends between the housings 5 in close prox imity to the rollerS.

passage of fire to A spindle 16, fixed within the casing, supports the reel 17, which carries the celluloid film 18. This film is drawn between the

rollers

8 and 9 through the slot 19 in the casing, being drawn off the reel between the rollers and through the slot in feeding and carried in the opposite direction onto the reel in winding, duplicate structures being used for feeding the film through the projecting-machine and winding it up after assing therethrougli. It will be understood t at in either drawing out or drawing in the film it moves freely between the rollers 8 and), because its thrust on the roller 9 will tilt the counterweight slightly. The counterweight causes the roller 9 to press the film against the rollerS, however. Hence when the film outside of the casing becomes ignited the flame can follow it no farther than the line where the rollers press it, thereby cutting it off. The hous ings, guard, and plates described combine with the rollers in cutting off the flame, which is left thereby no passage to the film on the reel or in the casing beyond the rollers.

Having described my invention, I claim 1. An apparatus of the class described comprising a fireproof casing, housings within said casing, a roller journaled in said housings, a second roller journaled in slots in said housings, and a lever havin a movable connection with said second rodler whereby the latter may be lifted into engagement with said first roller.

2. An apparatus of the class described comprising a fireproof casing, a reel journaled in said casing, an aperture in said casing, housings in said casing, rollers journaled in said housings, one of said rollers having spindles thereon movable in slotted supports therefor, and a broad lever extending between said housings and having inclined members for holding said rollers together.

3. An apparatus of the class described comprising a tight fireproof casing having a narrow slot therein, a pair of rollers within said casing adjacent to said slot, said slot and rollers being ada ted for passing a film, a filmreel supporter in said casing, and means coacting with said rollers for preventin the the film between sair reel and rollers.

4. An app prising a tight fire therein, a pair of r0 aratus of the class described coinroof casing having a slot lers within said casing adj acent to said slot, said slot and rollers being In testimony whereof I have hereunto set adapted for the passa e of a film, and means my hand this 5th day of April, 1905 in the coacting with said r01 ers for preventing the presence of the subscribi witnesses.
