SCUTTLE-HOLE PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 569,867, dated October20, 1896.

Application filed July l1, 1896. Serial No. 598,802. (No model.)

To all whom it may concern,.-

Beit known that I, ADOLF GANZENMLLER, of New York city, in the county and State of New York, have invented a new and Improved Scuttle-Hole Protector, of which the following is a full, clear, and exact description.

The object of my invention is to provide a protector applicable to roofs or other overhead structures at the scuttle-opening in said structures, being used auxiliary to the ordinary scuttle; and a further object of the invention is to so construct the scuttle-protec tor that should the scnttle be removed from over the scuttle-hole th'e protector will effectually prevent access being gained from the roof of the structure to the chamber or apartment beneath the scuttle-hole; and to provide means for expeditiously and conveniently7 opening the scuttle-hole to substantially its full extent and locking the protector in its protecting position.

The invention consists in the novel construction and combination of the several parts, as Will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure l is 'a vertical section through a portion of a root' containing a scuttle-hole, the scuttle, and the protect-or, the said section being taken practically on the line l l' of Fig. 2. Fig. 2 is a bottom plan view of the souttle-protector closed; and Fig. 3 is a vertical section through the roof and scuttle-protector, the section being taken substantially on the line 3 3 of Fig. l.

In carrying out the invention, A represents a roof, B the scuttle-opening therein, and C the scuttle covering the said opening and located on the roof.

The protector consists of a frame 10 of substantially skeleton construction, comprising a horizontal member and a hanged member at the outer margin of the horizontal inember. The opening in the frame of the protector is suiiioiently large to permit the passage of a person through the scuttlediole and is only of slightly less dimensions than the The opening dimensions of the scuttle-hole.

in the frame l0 is adapted to be closed by a door ll, having a hinged connection, preferably, with the under side of the horizontal member of the frame, and the said door is arranged to drop downward, and when closed its free end, or the end that is to drop, is located in a rabbet or recess made in the under side of the trame, as clearly shown in Fig. l.

The door may beheld in its closed position 6o by any suitable form of locking devices, as, for example, bolts l2 maybe mounted to slide upon the under face of the door at the edge opposite the hinges, and these bolts are made to enter keepers I3, secured to the under face 6 5 of the frame. Hangers ll are likewise projected downward from the under face of the frame l0, adjacent to the keepers for the bolts, and each hanger contains a pulley l5. A cord or rope 16 is passed over both of these pul- 7c leys, which are near opposite sides of the frame, and the ends of the cord are secured to eyes 1'7, or their equivalents, attached to the door at the u nder side,preferably adjacent to the bolts. 7 5

Instead of the bolts latches may be used, being, as illustrated, of angular construction, the` horizontal members of the latches sliding within guides 1S, secured to the under face of the frame, and these horizontal members 8o of the latches are of suiiicient length to extend over the edge of the door to an engagement with its under fac-e. Each latch is pivotally connected with a lever 20, and the levers are fulcrumed upon hangers or brack- S5 ets 2l, projected downward from the frame. The latches are preferably placed one near each side of the frame, as shown in Fig. 3.

In Fig. l the door is illustrated in dotted lines as partially dropped7 and when the door 9o is opened it is drawn upward by pulling downward upon the rope or cord 1U.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A device for protecting scuttle-holes consisting of a frame, a door having a hinged connection with the frame, the said door being arranged to drop downward, locking devices i'or holding the door in a closed posi- Ioo tion against the frame, pulleys located on the under side of the said frame, and a cord passing over said pulleys and havingits ends attached tothe under side of the door near its free end, asand for the purpose set forth;

2. A device for protecting scuttle-holes, the same consisting of a frame havingan opening therein of predetermined size, a door hinged to the frame and arranged to close the said opening, the said door having a hinged connection with the said frame and arranged to drop downward, locking devices for holding the door in closed position against the frame, hangers projected downward from the under face of the frame near opposite sides thereof and each carrying a pulley and a cord passing over the said pulleys, and having its ends attached to the free end of the door, as and for the purpose specified.

3. In a device for protecting scuttle-openings, a frame iitted to the scnttle-opening and provided with a dr0pdoor, means for raising the said door from a lower to an upper position, and locking devices consisting of latches fulcrumed iipon the frame and arranged to pass beneath the drop end of the door, guides for the said latches, and levers side of the horizontal member of the frame,

the said door being arranged to drop downward, the free end of the door when closed entering the said rabbet in the under side of the frame, locking devices arranged to hold the door in closed position, and means connected with the said door for raising the same from the open to the closed position, as and for the purpose set forth.
