HMamz LOUIS H. MANNING, OF PARMELE, NORTH CAROLINA.

WINDOW-BLIND.

Specification of Letters Patent.

Patented June 18, 1912.

Application filed January 13, 1912. Serial No. 670,998.

To all whom it may concern:

Be it known that I, LOUIS H. MANNING, a citizen of the United States, residing at Parmele, in the county of Martin and State of North Carolina, have invented certain new and useful Improvements in Window- Blinds, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in window blinds and more particularly to a shutter adapted for application to various windows, and my object is to provide a device of this character which is substantially fire-proof and which at the same time may permit air and light to pass therethrough, but which may not be operated from the outside.

A further object of the invention resides in providing a shutter comprising a movable member and a stationary member, each of which members is provided with slats, and a still further object resides in providing slats of an improved character which will permit of air passing therethrough when in their closed position.

Still another object of the invention resides in providing a device which is extremely simple and durable in construction, inexpensive to manufacture, and one which will be very eflicient and useful in operation.

With these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a front elevation of the device. Fig. 2 is a vertical section therethrough as. seen on line 22, Fig. 1. Fig. 3 is a perspective view of one of the stationary slats. Fig. 4 is a front elevation of the device showing the slats in their open position. Fig. 5 is a vertical sec tion therethrough as seen on line 55, Fig. 4. Fig. 6 is a horizontal section through the device as seen on line 66, Fig. 4, and, Fig. 7 is a perspective view of a keeper or the like used in connection with the raising and lowering means of the movable member of the shutter.

upper strip or bar 4 having its under or inner face grooved, as shown at 5, while the lower strip or bar 4 is provided on its upper edge with a tongue or strip 6 which extends the full width of said bar, and the side panels 2 have the inner faces thereof provided with the integral longitudinal strips or tongues 7 which extend from points adjacent the upper bar 3 to points contacting with the strip or tongue 6 on the lower bar 4; This frame formed of the side panels 2 and the upper and lower transverse bars 3 and 4, with their adjunctive parts, forms the stationary portion of my improved shutter, and secured to the longitudinal side strips or tongues 7 formed on the side panels 2, are a plurality of metallic slats 8 which are spaced at regular intervals from one another throughout the length of the frame 1. These slats comprise metallic plates bent to form substantially channel-shaped members, the channel portions of which are disposed downwardly and the side faces flared or inclined outwardly toward the lower edges of the same, and the ends of each face of these channel-shaped slats 8 are provided with inwardly bent triangular-shaped flanges 9, which flanges are secured in any approved manner to the longitudinal side strips or tongues 7 on the inner faces of the side panels 2. These flanges 9 of the slats 8 may be riveted or removably secured to the strips 7 but in any instance, they may be said to be stationarily mounted with respect to the frame. This frame 1 with the stationary slats 8 therein, forms a stationary portion of the device, but I have also provided a movable 0r sliding portion therefor which comprises a metallic bar or the like 10, which bar is bent to form a substantially U-shaped member or frame and rests against the longitudinal strips 7 and the tongues 6 on the one face of the frame 1, and the arms of this U- shaped frame or bar are bent upon themselves to extend over the upper edges of the strips 7 to contact with the opposite faces thereof, whereby said frame 10 will benslid ably retained in'position in the frame 1. From this construction, it will be seen that the frame 10 consists of pairs ofverticah bars spaced fromone another and disposed on opposite faces of the side strips or tongues 7 andalso comprises aba'se or h'ori zontal bar connecting one of the vertical-- bars of each pair, and secured to the pairs of vertical bars of this frame 10 in the spaces 1 between the slats 8 of the frame 1, are a plurality of additional slats 11. These slats 11 are formed in the identical manner that said slats 8'are formed, with the exception that the faces thereof are flared or inclined outwardly to a greater extent, so that the same may overlap or receive therein, the slats 8, and the slats are so mounted on the frames with respect to one another that when the movable frame is in its uppermost position, the lower portions of the slats thereof will overlap the upper portions of the stationary slats 8 so as to prevent light from passing therebetween. In this connection, it will be seen that the extreme upper and lower slats of the device are carried on the movable frame, and when this movable frame is in its uppermost position, the upper of the slats thereon will be received in the groove 5 of the transverse bar 3, while the lower slat will overlap the tongue or reduced strip 6 of the lower transverse bar 4. This structure is particularly shown in Fig. 2.

As stated, the construction above described is one wherein the sliding portion or frame 10 is in its uppermost position, but

when said frame is lowered so that the bend in the vertical arms of the device will contact or rest upon the upper edges of the longitudinal side strips 7 the channel-shaped slats 11 will be lowered to completely overlap the respective slats 8 of the frame 1, as shown in Figs. 4 and 5, and in this position, it will be seen that the spaces between the slats 8 will be open to allow light to readily pass therethrough. It will be appreciated that air may readily pass through the slats when the same are in their closed position,

i that is, when the frame 10 is in its'raised position, as shown in'Figs. 1 and 2.

I have provided for the manual raising and lowering of this movable frame 10, and

to this extent, a stem or the like 12 is secured to the horizontal bar of the U-shaped frame 10, the stem depending downwardly j through guide openings in a keeper 13,

which keeper 13 is countersunk in a recess or the like formed in the front face of the transverse bar 4. The stem 12 has formed thereon, a laterally extending arm 14 which adapted to receive the arm when said frame 'is'in its'l'owermost position, and thus it will be seen that the sliding portion may be held in either of its adjusted positions. Of course, it will be understood that when the face of the frame 1 having this operating portion disposed thereon, is described as the front face, such front face refers to the face of the shutterwhich is disposed inwardly so as to be operated from within the structure having this shutter mounted thereon, and in this connection, it will be seen that when the movable portion of'the shutter is disposed in proper position, the same may not be operated from the outside. To this extent, the device is burglar-proof, and the slats being formed of metal, it might be stated that the device is substantiallyfireproof. It will also be seen that in either position of the movable frame, fresh air will be permitted to pass through the slats and light mayonly be allowed to pass therethrough when the movable frame is in its lowered position.

From the foregoing, it will be seen that I have provided simple, inexpensive and efficient means for carrying out the objects of the invention, and while I have particularly described the elements most well adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what I claim is 1. A device of the class described, comprising a main frame having channel-shaped slats therein, and a movable frame mounted in the main frame also provided with channel-shaped slats disposed between the slats of said main frame, said latter slats partly overlapping the first mentioned slats when the movable frame is in its raised position and adapted to receive the same when said frame is in its lowered position.

2. A shutter of the class described, comprising a main frame, the side panels of which are provided with longitudinal strips,- a plurality of channel-shaped slats secured to said strips, the channel portions of which are disposeddownwardly, a movable frame, the side bars of which are straddled over said longitudinal strips, additional channelshaped slats secured to the side bars of the In testimony whereof I hereunto aflEiX my movable frame andf disposed between the signature in the presence of two Witnesses. slats of the main rame said latter slats partly overlapping the first mentioned slats LOUIS MANNING When in one position and adapted to receive Witnesses:

the same when in another position, and C. O. GREGG, means to operate said movable frame. M. P. MANNING.
