WINDOW SHADE FIXTURE Filed May 27, 1931 1271/71/71 /z/ III/III Patented Apr. 19, 1932 ABRAHAM ISADORE COLEMAN, 0E BALTIMORE, MARYLAND WINDOW SHADE rrxrunn Application filed May 27, 1931; Serial No. 54 0,338.
The object of the invention is to provide an automatically adjustable window shade fixture which will adapt itself instantaneously to shade rollers of different lengths.
An important source of annoyance to the owners of rented housesand apartments and of disfigurement of such tenements is dueto the practice on the part of the difierent tenants of installing new shades having rollers of varying lengths requiring new fixtures or a relocation of the old fixtures. In old buildings where changes of tenants have been frequent, the window casings have become honeycombed with screw holes where numerous fixtures have been installed and re moved, and even though these holes are puttied from time to time when the woodwork is painted, it becomes diflicult after a while to find a sufficient hold for the screws which support the fixtures. Also, the woodwork itself becomes unsightly in appearance.
The fact is known to this inventor that various patents have been issued on automatically adjustable curtain or shade fix tures, but the adjustable feature is so designed and constructed that on account of its bulk it must be located outside of the area covered by the shade and beyond the end of the roller and all of such devices are therefore conspicuous and unsightly so that this type offixture has never become popular andthe-fixtures-constructed in this way have therefore never proved to be a commercially successful product. g The fixture which is the subject of the present invention is on the contrary, so devised that the adjustable feature is conveniently concealed behind the shade and the shade roller, the adjustable feature being so thin and laying so flat against the window casing that the shade roller easily clears it when this portion hind the shade roller. The device is also capableof easy and quick production in large quantities at such a low cost that it can be made at a profit to be sold at an extremely low price, being available for distribution by the five and ten cent stores and similar organizations.

In the accompanying drawings I have ilof the fixture is turned inwardly belu-strated an automatically adjustable window shade fixture or support, together with so. much of a window shade as lsnecessary to a full comprehension of the invention and the manner of constructing, operating and using the same. Y
In the drawingsz' a l Figure 1 is a perspective view of a fragment of window frame of the invention'also shown in perspective is secured inoperative position, a fragment of window shade and roller being shown in dotted lines in position on the fixture.
to which the fixture Figure 2 is a perspective view on a reduced scale of a window shade supported on the automatically adjustable fixtures of the invention, the same being securedto a window frame and having the shade supported thereon in operative position. Referring to the drawings by numerals, each of which is used to indicate the same or similar parts infthe difi'erent figures, the construction showncomprises a'base plate or foot plate 1, adapted to be secured to the window shade by means of screws 2, passing through suitable holes in the baseplate, the same bein indicated by reference character 3, and asliding fixture member 45, consisting of a sheet metal'strip bent at right angles to form a sliding bar or follower 5, and a roller arm 6 at right angles thereto. The base plate or foot plate 1 in the form of the invention shown is provided with loops or' eyes 7 formed by slotting the sheet metal forming the base 1, and bending it backwardly out ofline with the main portion of the base plate 1. These loopsor eyes 7 are shown as formed on each edge of the plate 1 and ar-. ranged in alignment so that they provide ways for the sliding bar or follower bar 5, which extends through these ways transversev ly to the base plate 1 as shown. The plate 1 forms one side of these ways and the sliding fixture rests against it. The roller arm 6 is perforated or slotted at 8 at its outer. end, the portion surrounding the slot being preferably upsetorv bossed as at 9, to contact the end of the roller, giving a reduced contacting portion to reduce the frictional engagement. The sliding bar 5 which is elongated as sired shoulders or abutments serving to support the end of the spring. 7 v 1 It will be understood from the description that the device of the invention is easily and quickly formed from sheet metal by stampe ing the baseplate 1 with theholes 3 and the rectangular loops '7 aligned to form the ways.
5 The slidingfixture member 4 is then formed of a longer strip of sheet metal bent at right angles as previously described and perforated. or slotted at 8, or 8', Figure 2. The sliding or follower bar 5 is then passed through the. loops or ways 7 and through the spring 10 after which the shoulders 11 are formed outside the spring by displacing or drawing. these portions outwardly in any convenient manner as by means: of a prick punch punching the holes 12 and displacing the metal as shown. I
The fixtures being thus'as'sembled are arranged in pairs one having the perforation 8 and the other the slot 8 as shown in Figure 2. These fixtures when purchased by the consumer are secured to the window frame in a position corresponding to the length of the shortest roller which would be used, and when a suitable shade 14 and roller 15 have been selected for the window, the round pin 16 at one end of the roller is inserted in the perforation 8; and the roller being thrust to the right in the illustration and thefixture at the left being if necessary drawn somewhat to the left against the compression of the spring 10, the flat pin 17 at the left end of the fixture is. inserted in the slot 8', after which thesprings 10 reach a balance or equilibriumand the installation of the shade,
roller is complete.
The ease and cheapness with which the fixture can be produced in quantities for sale at a low price will be understoodvand appreciated from the description of the construction and the manner of assembling described above. The convenience of the construction and its adaptability to all conditionswhich would be encountered in the in stallation'of window shades and. rollers as well as other types of rollcurtains will also be appreciated. It is of'particular importance that the device is made available for practical use not only on account of its cheap and economical construction but because'of the fact that the adjustable feature is so compact and so flat and of such short dimension normal to the plane of the window that it can be concealed behind the roller relieving the assembled shade and fixture of any objectionable appearance of complicated mechanical structure or of any conspicuous details which are difl erent fromtheordinary type of shade fixture. This is regarded as an important element in making the device acceptable to the trade.
I have thus described specifically and in detail an automatically adjustable window shade fixture embodying the features of my invention in the preferred form in order that the manner of applying, using and operating the same may be'fully understood,dhowever,'
the specific terms'herein are used descriptively rather than in a limiting sense, the scope of the inventionbeing defined'in the claims. 7 H 7 What I claim as new and desire to secure by Letters Patent is I V 1. An automatically adjustable window shade fixture comprising a base plate, having transverse ways, a sliding fixture member comprising a supporting arm normalto the base plate, a flat sliding bar which extends through the ways in close proximity to the window frame and a fiat 'coil spring encircling thebar, one end of said spring bearing against the slidingmember, the other end of the spring having a fixed support whereby the spring tends to slide the bar through the ways and to hold the supporting arm in the position of adjustment rious lengths. v 2. The combination in an automatically adjustable curtain shade fixture of a base plate having transverse ways, a sliding'bar in said ways and bearing close against the base plate, and adapted to extend inwardly behindthe shade roller, a coil spring encircling the bar and bearing atone end against the base plate, the sliding bar having 'a spring abutment at its end, and having at its opposite end a roller supporting arm normal to the plane of the base plate.
