'HOO'D FOR ROLLING FIRE-RESISTING GUFiTAINSfi no. seaees.

To 02% whom it may concern:

Be it known that I, EDWARD H. McCLoUn,

a citizen of the United States, residing at Golumbus, in the county of Franklin and State 5 of Ohio,.have invented certain new and useful Improvements in Hoods for Rolling Fire- Resisting Curtains; and I'do hereby declare the following to be a full, clear, and exact description ofthe. invention, such as willenable others skilled in the art to which it appertains to make and use the same.

The objectof this invention, generally stated, is to provide an improved construction of hood for use in connection with rolling fire-resisting curtains for closing door, windoW, and other openings whereby sparks and .flame arejin a large measure or wholly precluded from passage through or around the hood.

The invention is embodied, generally speaking, in a supplemental hood or shield connected with the-hood proper and adapted to lie on orin close proximity to the curtain orrollertoclose the passage or opening between the curtain or its roller and the hood and means whereby such supplemental hood is held up away from the curtain or roller and back portions alone on the line y y, Fig. 7,

also on alarger-scale. Fig. 3 is asectional view, on a larger scale than seen in Fig. 1, of the device for holding up the supplemental shield. Fig- 4 is an exterior view of the device for holding up the supplemental shield. Fig. 5 is a detail, partially in section, of the means whereby the supplemental shield is held upn Fig. 6 is an elevation of the inner side of the back of the hood. Fig. 7 is a top plan view of the hood, and Fig. 8 is a horizontal sectional fractional detail of the back.

Specification of Letters Patent. Application filed February 2.1906. seen N... 299,219.

Patented Feb. 5, 1907.

In the several views, 1 designates the outer or e posed part of the hood. This hood is of senncyllndric form and-is preferably made of sheet metal and bent along its upper side to metal, provided with grooves at their upper edges, into which fits a flange 1 of the outer portion 1. Theback portions 2 and 2 "at their lower portions are bent to stand outward from the wall, and their edgesare formed with strengthening-beads, which also constitute one side of the opening to the hood through which the curtain passes. These back portions 2 and 2 are secured at their outer ends to the'wall and are separated at their inner ends by a space ample to permit the free expansion of such portions due to rise in temperature.

The space between the inner ends of the portions or sections 2 and 2 of the back is closed bytwo plates 3 and 3 of metal fitting on opposite sides of said portions. These lates are held apart by a strip of metal 4:, cut at its lower end to conform generally to the bend of the lower edges of the portions 2 and2. The strip l can be supplemented by a further strcngtl1ening-strip 4: of the same kind and form, fitting on the outer side of the plate 3 and bolts 5 are passed throughround holes in the plates 8 and 3 and strips 4 and 4 to secure them all rigidly to the wall. At their inner ends near the space between them the back portions 2 and 2" are made with elongated openings, (indicated bybrokenlines Fig. 6,) and through these, as well as the plates 4 and 4 rivets 6 are passed to secure said parts together, but not so as to prevent the expansion of the back portions'and the plates due to a rise of temperature. At its lower end the plate 3 is shown to be bent and rolled to embrace the beads on the portions 2 and 2 The object of this construction of the back wall is to prevent the buckling of the hood where it fits against thebuilding,-

means of bolts 9. l The same bolts 9 can be i used to fasten up the back portions 2 and 2.

g The end brackets are provided with lugs or shield.

projections 10 and 10 (conveniently cast with the end' brackets) to stand opposite the ends of the hinge and prevent the endwise movement of the supplemental shield and close said ends where they are open,

Y 11 desi ates the sup lemental or interior his shield is shown to be bentand provided at one edge with a bead adapted to enter the bead 1 at the upper side of the hood roper'and be capable of a rocking or hmge like movement therein. Other forms of hinge can be employed; but that shown and described presents no openings along its.

outer side and is therefore advantageous preventing the access of dust, Water, &c., at such openings, In the form of hinge shown the shield is retained in place by reason of the fact that the opening to the bead P on the hood proper is made smaller than the bead on the shield, and the connection of the shield with the ,hood is eiiected by sliding endwise the bead of the shield into the bead, of the hood before the hoodissecuredinplace on the wall. The shield can have its free edge weighted and braced by means of. a bar at its edge, as indicated at 11*.

Where the curtain is frequently rolled and unrolled, it is not so desirable that the shield shall rest continually on the curtain. Hence I provide means for holding the shield up, said means being adapted to eiiect the liberation of the shield upona dangerous rise of temperature. For'this urpose the, shield is provided with a hoo 11", secured thereto, and the hood with catch 12, adapted to e age said hook, said catch being attached y a solder adapted to fuse on a dangerous rise of tem erature, and so release the hook and shield To make the hook accessible to lift the shield after the hood has been mounted in place, I provide the hood with an opening walled by a small frame 1, and through this opening a bent instrument can be inserted to engage a hole 11 in the back of the hook 11 The catch 12 is preferably soldered, as indicated at 1 2, to the inner side to a slide 13, adapted to close the opening of the hood, the frame 1 being providedwith grooves to reoeive the edges of the slide. To connect the said catch with the hook of the shield, the latter is held up by the aforementioned bent instrument until the catch is slid partially onto the hook and in shield-holding engagement therewith, after which said instrument can be removed and the slide further movedto close the opening. Room is of course left @5 roller to close the space between said curtain or roller and the hood proper.
