JOHN M. ABBOTT, on TAMA CITY, IowA, ASSIGNOR OFONE-HALF or HIS RIGHT TO E. HARMON.
INSIDE BLIND.
SPECIFICATION forming part of Letters Patent No. 223,973, dated February 3, 1880.
Application filed October 22, 1879.
To all whom it may concern:
Be it knownthat I, JOHN M. ABBOTT, of Tama City, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Venetian Blinds; and I do hereby 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 'of reference marked thereon, which form a part of this specification.
My invention relatesto certain improvements in Venetian blinds.
Heretofore Venetian blinds have been. of very complicated and cumbersome constructions, and by reason of the expense involved in their manufacture they have failed to become popular in use. The manner heretofore used of connecting the slats of Venetian blinds has been very defective. Ordinary knots and similar fastenings have been employed; but such devices are soon impaired by use, and the ends of the slats drop below their original positions, and thus the appearance of the blind is rendered unsightly and irregular. Again, the devices designed to incline the slats of Venetian blinds, as heretofore constructed, are
3o unnecessarily complicated and liable to frequent breakage and displacement, and by these means rendenthe blindsdifticult to operate and unhandy in use.
The object of myinvention is to obviate the 5 defects above noted, and to provide a blind which shall be simple in construction, but effective and desirable in use, and at the same time be of moderate cost in manufacture.
My invention consists in certain details of 0 construction and combinations of parts, as will hereinafter be described and pointed out in the claims.
Referring to the drawings, Figure 1 is a front elevation of the window-frame and blind 5 with the slats inclined orfolded together. Fig.
2 is a perspective view with the slats in ordinary open position. Fig. 3 is a perspective view, showing the blind partially drawn up. Fig. 4 is a detached perspective view of the top bar 5 and Fig. 5 is a detached enlarged View, showing the manner of connecting the slats together.
A represents the window-frame, having the journal-brackets on B represents the oscillat ing top bar,journaled in brackets to, and formed 5 5 on its under side with a longitudinal groove,
11, into which is secured, by cross-bars or other means, a rod, b, which latter projects slightly at opposite ends of-bar B, thus forming journals b b the latter one of which is formed l with two cord-arms, O G, to which cords d are attachedjor oscillating the bar and thereby inclining the slats. The slats D are secured together by thelooped cords E, passing through the eyes 6 of the slats, said loops being firmly 6 5 secured in the eyes by the small wedges c.
It will be observed that by this arrangement of the slat-connections all complicated fastenings are dispensed with, and in lieu of an unsightly knot at each fastening I employ a neat single loop secured by a wedge, and hence there is no liability of one or more of the fastenings becoming loose, thus causing the ends of the slats to drop down, therebyimpairin g the uniformity and beauty of the blind.
The center cord, F, is permanently fastened to the lower slat, and passes loosely through openings in the center of each of the several slats and the top bar, and through an eye in the center of the top rail of the window-frame, 0 and thence through eyes to one side of the frame, terminating in a ring or finger attachment, f, by the aid of which the blind is readily raised or lowered, as desired.
The side of the frame may be provided with 5 any number of catchesf, onto which the ring f may be secured to retain the blind in any desired vertical adjustment.
The manner of operating the blind is as follows: By pulling on the cord F the blind is readily raised, and may be retained in such position by securing ring f, as above set forth.
.To incline the slats either toward the front or back it is only necessary to pull one of the cords d, which latter may also be secured, if desired, to one of the catches f. Thus the air or light may be excluded from an apartment by one sitting near the window by simply exerting a slight strain on the operatingcords.
From the foregoing it will be observed that my improved blind is neat in appearance, durable in use, and may be constructed at small cost; and it will be further seen that it effects in the simplest manner and with the least complication of parts the results desired.
It is evident that many slight changes in the form of the several parts of my improvement and in the details of construction thereof may be resorted to without departing from the spirit of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In aVenetian blind, a top bar, 13, having a rod, 11, secured to its under side, said rod tinuously-looped cords and Wedges, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand.
JOHN M. ABBOTT.
