FIREPROOF DOOR, SHUTTER, AND THE LIKE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed February 7, 1907. Serial No. 356,177.

To all whom it may concern:

Be it known that 1, FLOYD W. NEWMAN, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented new and useful Fireproo'f Doors, Shutters, and the Like, of which the following is a specication.

rFhis invention relates to iireproof doors, window Shutters, gates, etc., of the folding or collapsible type and its object is to provide a device of this character made up of telescoping sections having. means whereby the device can be quickly collapsed or folded into a compact mass. I

A still further object is to so construct the device as to render the same easy to operate.

Wlith these and other objects in view the invention consists of certain nov'el features of construction and combinations of parts which will be hereinafter more fully described and pointed 'out in the claims.

In the accompanying drawings is shown the preferred form of the invention embodied in a door.

In said drawings: Figure 1 is a section through the door the same being shown ex- Y tended or closed; Fig. 2 is a similar view Showing the door folded or collapsed Fig. 3 is an enlarged horizontal section through a portion ofthe door extended the connecting links, controlling rods and the ears to which said rods are pivoted being removed for the sake of clearness; Fig. 4 is a view partly in section and partly in elevation of a portion of the upper part of the door and casing, Fig. 5 is a vertical transverse section through the lower portion of the door, the door section being shown with its walls each formed of a single thickness instead of hollow, as shown in Fig. 3; Fig. 6 is a similar view through the upper portion of the door and its casing, the door sections in this view being also shown with walls of a single thickness. Fig. 7 is an elevation of the lower portion of one of the door sections. Fig. 8 is a section through a portion of the door and through the slotted guide tube therein.

Referring to the figures by characters of reference, 1 is a door casing formed of sheet metal, one of the j ambs 2 thereofconstituting a housing for the door when the same is collapsed. The top 3 of the door frame also constitutes a housing for the upper ends of the door sections.

rlhe door is made up of a plurality of sections each of which is preferably constructed of sheet metal. Each wall of the section consists of a sheet of metal folded upon itself to form an outer portion 4 and an inner portion 5, one end of the outer portion being bent inward as shown at 6 and riveted or otherwise secured to the adjoining portion of the inner portion 5. The two Walls of the section are connected at their rear ends by a back plate 7 which extends throughout the height of the section and is provided intermediate its ends `with a shoulder 8 extending transversely ofthe section and provided at the center thereof with a slot 9.

The sections of the door are each closed at the bottom as lshown at 10 said bottom being curved upward from the front or open end of the door section to the rear or closed end thereof and is concavo-convex in cross sec tion. A groove or channel 11 is struck downward into the bottom of each door section and extends from front to rear thereof. This groove is of sufficient width to receive a roller 12 mounted on a shaft 13 which is secured beneath the higliest portion of the bottom of the adjoining door section.

The inner portions 5 of the walls of each door section have oppositely disposed slots 14 registering with slots 15 formed longitudinally within pipe sections 16 secured within the walls of the door section. Asbestos or other suitable fire resisting material 17 is packed around the tubes 16 and entirely fills the space between the inner and outer portions of the walls of the door section. A rod 18 extends through the walls of each door section near the back plate 7 thereof and has laterally projecting ends on which are disposed guide rollers 19. The ends of each rod are adapted to project through the slots 14 and 15 of the adjoining door section and the heads 19 are' adapted to travel withi'n pipe sections 16.

It is of course understood that the door sections are all. of different widthsso that they can telescope as shown in Fig. 3 and the shoulders S are disposed atdifferent distances from the bottom of the door as shown in Fig. 1 so that a connecting rod 20 which is pivoted within the housing 2 as at 21 can extend through the slots 9. Depending from each shoulder 8 adjacent the slot 9 is an ear 22 to which the rod 20 is pivoted. Parallel links 23 are pivotally connected as at 24 to the outer faces of those door sections adjoining the housing 2 and are pivoted at their lower ends as at 25 to the inner faces the door is folded these links will assume positions between the sections. The remaining door sections are similarly connected adjacent their lower ends by links 26. Ears 27 extend from the front of` each door section at the sides thereof and on a line parallel with the rod 20 and pivoted to these ears and extending along the outer faces of the door sections are controlling rods 28. The pivot 2l of rod 20 consists of a rod which extends through the walls of the housing 2 and is provided at its outer ends with actuating arms 29 having grips or handles 30.

rI he upper ends of the door sections are curved so as to be parallel or concentric with the bottoms of said sections and extending laterally from the upper portion of each door section are angle irons'31 adapted to rest upon ledges 32 extending inward from the top of the door frame as shown in Fig. 6. It is of course understood that the outer door section has its front face closed as shown at 33. It is of course understood that when the door is closed or extended the rods 18 assume positions in the front ends of slots 14 and 15 thereby preventing the sections from moving apart. Also the rollers 12 rest upon the floor as shown in Fig. l and the angle irons 31 contact with the ledges 32. When it is desired to open the door or fold it the operator swings the arms 29 upward. This will cause the strip 20, which is keyed or otherwise secured to rod 21, to also swing upward and as it is pivoted to each door section all of said sections will be simultaneously swung in an arc concene tric with pivot 21. The rollers 12 will ride upward within the channels or grooves 11 and as the links 23 and 26 are parallel with the rod 20 the upper and lower ends of the sections of the door will be maintained in proper relation. When the rod 20 has been swung into an upright position the sections of the door will be nested as shown in Fig. 2 a-nd will be entirely disposed within the housing 2. In view of the fact that the door sections travel into each other upon the rollers 12 and the inclined bottoms 10 it will be obvious that the power required to collapse the doorl need only be suiiicient to draw the sections upon the inclined bottom 10. Vhen the door is closed it constitutes an efficient fireproof closure which is not objectionable in appearance and which practically conceals the connections between the sections thereof.

It will be noted by referring to Figs. 5 and 6 that each of the door sections have their side walls converging upwardly. As a result of this construction, the sections, when the door is collapsed, as shown in Fig. 2, will bind within each other. When, however, the sections are swung outward and downward to close the door, the sections will be moved out Of binding position and vill promptly drop to the position shown in 1ig. l.
