UNITED STATES PATENT OFFICE.
WALTER A. HOLBROOK, OF MILXVAUKEE, \VISCONSIN.
INSIDE SHUTTER.
SPECIFICATION forming part of Letters Patent No. 320,786, dated June 23, 1885.
Application filed January 23, 1895.
To all whom it may concern:
Be it known that LWALTER A. HOLBROOK, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Inside Shutters; and
I do declare the following to be a full, clear,
and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.
Figure l of the drawings is a vertical sectional view of this invention. Fig. 2 is a front View of the same, and Figs. 3, 4, and 5 are detail views.
This invention relates to improvements in inside window blinds or shutters, and has especial reference to the class of blinds which are arranged to slide vertically in a suitable frame in front of the window-sash.
The invention consists in the construction, combination, and adaptation of devices, as will be hereinafter more fully set forth and claimed.
In the accompanying drawings, A represents one style of blind easing or frame,of general rectangular shape, and secured to the inner side of the window frame, so as to form an ornamental finish thereto.
In bay-windows strips may be "worked in with casings, presenting in appearance an extension of the jamb. a a are the side strips of the said casing, each preferably having formed upon it the two similar longitudinal grooves B and B, the grooves on each side looking inward and being arranged opposite those on the other side. 0 G are similar and equal blind-sections sliding in the grooves B nearest the sashes. The section 0 is arranged nearest the top of the window, and the section 0 nearest the bottom thereof, and the two are connected together and hung in the casing by means of cords or chains, in a manner hereinafter explained.
Instead of forming grooves B and B in side strips a a, they may have as an equivalent, tongues formed upon these grooves and worked in the edges of the sections, allowing the sliding of the sections as before.
(No model.)
D D are blind-sections similar to O C, and sliding in the grooves 13, the section D being above D. These four sections entirely close the window when in proper position, D and D being connected together and hung similarly to O G.
F is a pulley secu el in one of the side strips a, in and near the tops of the grooves B, and f is the actuating-co1-d,which connects the sections 0 and C in the following manner: One side edge of the sect-ion O is provided with a vertical groove, 0, in which a cord or chain, f, is secured by proper means. but preferably by a device hereinafter described. The cord passes up out of the groove 0, over the pulley F, and thence descends in the said groove 0 to the pulley I, secured in the lower part thereof, around and below which pulley it passes inward through a proper opening into the groove B, and is secured by proper means to the side edge of the lower section, 0, of the 38.11. 1 41 is an idler or friction pulley immediately below the pulley I, in the same casing or block, and having the cord f passing over it or between the two pulleys.
The following is the device for securing the cord in the groove 0: G is a metallic loop, having a conical top, through an opening in which the end of the cord runs, and is knotted or otherwise secured below. H is a metal plate, secured to the lower edge of the section 0, with its end projecting under the groove 0, and h is a screw passing through an opening in said plate into the groove and engaging in a properly-thrcaded opening in the loop G. By means of the loops G and screw h the cords f may be tightened or loosened to make the sections move evenly and easily in the grooves.
The sections D and D are connected together by the cords or chains j j, which pass over pulleys J, similar to the pulleys F, but situated in the grooves B, in which the latter sections move. The cords j also pass near the lower ends between pulleys K h.
To hide the cords on the outside of the strips a, the moldings L are placed outside of said strips, as shown, the moldings being longitudinally grooved, so as not to interfere with the motion of the cords.
It is evident from the foregoing description that when the section 0 is drawn down the cords ff will pull the section 0 to a corresponding distance upward, and that, as the sections have the same weight, the friction of the mechanism will be sufficient to retain the sections where left in the grooves 13. The same is true of the sections D D, moving in the grooves B.
M are metallic plates or catches, fixed to the lower edge of the section D, which, when the latter is drawn down, will strike against similar catches, m, on the lower edge of the section 0, and will depress both sections at the same time, also causing the upper two sections to rise, so that one motion will move all the sections at the same time and remove them from before the window. In this position, when the section D is moved upward, the catches M will strike against similar catches, m, in the upper edge of the section 0, and move the same upward, the upper sections being depressed, so that the blinds are drawn over the window at one motion.
The advantages of the two sections of a pair moving in the same groove are that it saves space within the room, is of simpler construction, and allows the sections to lie closer to-" gether and closer to the plastering. It also makes a less expensive and more finished job.
The doing away with the boxes or chambers to receive the sections also saves expense. The projecting strips a a allow the uncovering ol' the whole window without boxing.
Having thus described this invention, what I claim, and desire to secure by Letters Patent, 1s
1. In a sectional sliding blind, the arrangement of an even number of sections into counterbalancing pairs in such manner that the middle two sections shall form one pair, the next higher and next lower section another pair, and so on, the members of each pair being so connected by cords or otherwise that depressing the lower member will correspondingly raise the upper member, substantially as specified.
2. In asectional sliding blind, the combination of the counterbalancing sections 0 and 0, moving in the grooves 13, or their equivalents, the latter section being provided with the catches m and m on its lower and upper edges, respectively, with the similar counterbalancing sections, D and D, moving in the grooves B, or their equivalents, the latter section being provided with the catch M, substantially as specified.
3. In combination with inside windowblinds made in sections, the projecting side strips,
a a, fixed to the inside of the window and provided with grooves 13 B, or their equivalents, allowing sections to slide in front of plastering and uncover the whole window, substan tially as specified.
4. In a sliding sectional blind, the combination, with the casing A, sections 0 O, and pulleys F and I, of the cord f, metallic loop G, plate H, and screw h, substantially as specified.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of lViscousin, in the presence of two witnesses.
