Be it known that I, G. M. McMAHAN, of Mount Sterling, iu the county oi Montgomery, and State of Ken- -tuc'lry, have invented a new und improved Combined Window' and Door-Blind and Awning; and I do hereby declare the following to be afull, clear, und exact description of the same, suiicient to enable those skillediin the art to which my invention' nppertains to make use ofit, reference bein'g had to the accompanying drewings, forming part of this'specilication, in which f i Figure 1 is a front elevation. l

Figure 2, a sidelvicvv.

Figure 8, adetached view of the roller.

Figure 4, a detuched'perspective view, showing the construction of the awning; and Figure 5, a detached view, showing the construction and operation ofthe latch by which the blinds are fastened down, i

p In this invention a. metallic awningis so constructedthat, when desired, it can be let down and fastened,'so its toiform c strong metallic shutter or blind, for the protection of the doors and windows'of the building.`

I construct the awning of a. series of long'plates, A A, of cast iron, or other suitable metal, united at their edges by interlocking grooves and flanges, as shown at a a -The plates thus united, when' used us an' awning,` project from the wall B of the building, in an inclined position, as shown in figs. and 2, and are supported by nent metallic rods or posts'C C. These rods are hinged at their upper end to the lower end of the plates, in such a manner that they can be folded up' under the`plates when it is necessary to lower the awning, 4 and `tlieir-V ends may be fastened up under the plates, by small hooks or snaps c e, fixed to the under side of the plates, nea-r the wall B B. In iig. 4 the end of the rod C is seen'folded up against the awning, and secured in that position by the snapt'. Y v A -The awning thus constructed isfraised and lowered by moans of s series of cords I I I, wound upon s. rolliff D, which is operated by a gear-wheel and cr'ank, E. By this means all the plates thatcompose'the awning are` equally raised or lowered together, by simply turning thecrank. Both the roller andthe crank are on tl'ii inside of the building. v The awning is hinged to the front side of the building, above lthe windows and doors, andA is made of such a lengh that when lowered, so as to hang from its hinges against the side of the wall, it completely `covers the windows and doors, and when continedin that position renders the building comparatively safe from the operations of burglar-s. Any simple arrangement of lock, husp, latch, or catch may be usedfcr confining the lower edge ofthe awning when it is thus lowered. The torin of latch shownoat m, iu iig. 5, I regard i es being, vin all respects, perhaps, as neat, simple, andservice-able a. device as can be employed for the purpose. A narrow inclined strip or water-shed, F, is attached to the front of' the building, just above the hinges of the awning, for the purpose of protecting the hinges and cords from the weather, and of preventing snow or rain from driving into the building through the apertures in which the cords operate. This strip maybe made very ornamental to the building, it' desired. The cords pass under it, over pulleys it thought necessary, and through tubes which protect them from` the weather. The tubes may even extend through th wallofthe-bnilding, furiiishing the only opening necessary to be made in thewalls, for the passage. ofthe cords, and thus eectually. securing the building against the admission of snow, rain, or cold air atthis point. 2

4,The apparatus as thus constructed isY simple, and can be made and attached to buildings at va. moderate expense. During the 'day it will furnish a.r strong-waterproof awning, that will resist any violence of the wind," and at night itwill form an iron shutter, covering and protectingsthe whole front of the lower story.

It is hardly necessary to say that this device may be employed in connection with a single window or door in any part of the building, for that, when constructed as above described, that portion which covers thedoor may be made separate vfrom the rest, so that after the restV has been locked down, the clerk or other person inside .ofthe building may pass out through the door, and lock that part ofthe shutter after him which covers the door, by means of a. padlock, or common door-lock. j i i* Having thus described my invention, vrhntIclaim as new, and desire to secure by LettersPatent, is---,`

1. The metallic aivning'herendescribed, composedlpf the strips A A, provided with overlapping uuges and grooves c a', and hinged to the building, so us to becapablo of being'lowered.' and fastened down, so as to form a metallic shutter or blind, for the iprotection of the doors or windows of the building, substantially as described. j 1 l f 2: In combination with the foregoingfI claim the catches-or locks Vm m, cords I I, roller` D, and crank E, substantiilly as and forthe Hpurposespecified.u i f G. M. MMAHAN.
