Application filed March 16, 1931. Serial No. 522,810.
. The present invention pertains to a novel window shade'rolleradjusting device of a type particularly adapted for use in combination with either casement or double hung windows.
In'residences orpublic buildings having a number of symmetrlcally arranged .w1n-' dows it is' desirable that the window shades should all hang so that thelower ends of all the shades are level. Ordinary window shade rollers are equipped with two pawls which hold the roller against backward rotation as result of pressure of the. spring contained therein and these pawls are only capable of stopping the movement of the roller after it has travelled a half revolution and the re- 7 sult is that the lower'ends of the shades can 1 only be adjusted within a range correspond" ing to theamount of the shade which is unrolled by ahalfrevolution of the roller. The only manner in 'which the shades can beaccurately adjusted is by taking down the roll and cutting a portion of the shade away and this obviously takes conslderable tune and expense and therefore the present invention contemplates the provision of means for in? expensively and accurately adjusting the Window shades so that any number of them may be arranged so that theyunroll so that their lower ends will belevel. I V
The present invention further contemplates the provision of an ad ustable supporting device for the shade roller which makes it impossible for the shade roller to be removed accidentally. 7
With the above and other ends in view the invention consists in mattershereinafter set forth and more particularly pointed out inthe appended claims,-reference being bad to the accompanying drawings, in which Figure 1 is a fragmentary view of a window shade roller having'one end supported in one of the present adjustable supports;
Fig. 2 is a side elevation of the outer face of the present device; I h
Fig. 3 is a side elevation of the inner face; Fig. 4: is an illustration of the ratchet faced disk which holds the-shade inany'position of adjustment;
Fig. 5 is a side elevation of the supporting bracket. I
Fig. 6 illustrates the adjustable device in combinationw-ith a bracket adaptedifo'r use in combination anch V Fig. 7 is a top plan View thereof.
Like characters 'of reference are employed throughout to designate corresponding parts.
In Fig. 1 the numeral 1 indicates a convene 1 tional window shade mounted in the usual manner upon a roller? Within the roller is a mechanism which causes the roller to roll the shade thereon and according to conventional standardsthe roller is provided with 5 means capable of stopping movement of the roller backwardly at intervals of every half revolution providing the projecting angular member? is held against rotation in a suitable bracket. this projecting member 3 by means which ordinarily prevents l rotation thereof. but which will permit .rotation thereof under certain conditions for the purpose of adjustmentwhen'such is desired. I 7
A 'bracketvl'is'provided with a pair of ears, 5 arranged at right angles theretoto facili- I tate' its attachment tora window. The bracket is dished as at 6 to torma dome shaped pore tion projecting toward the roller and inthis dome shaped portion is formed a keyhole slot 7. I
; A. plurality of cars 8 are formed. on the bracket etand are bent-over the edge of a disk9 which is dished as at 10 to fit over the s with double hung window, 5
The present invention aims to hold on the'fa-c'e of the bracket .4 and a series of,
so that. the projection 12 extends into One of the notches to ordinarily resist rotation of the di k ;.re ative in the ra e lnusiegt e pr sen e i Wil b d scuba i a p ies t 9 n d of the roller and in order to mount the roller therein the two slots 7 and 11 are aligned as illustrated in Fig. 6. After the member 3 is inserted in the aligned slots the disk 9 is rotated a part of a revolution so that the slots are no longer in alignment with each other, this latter position being illustrated in Figs. 2 and 3. When the slots are out of alignment in this position the member 3 cannot be removed from the slots.
If the lower ends of the shades can not be adjusted to the correct height by means of the conventional pawl and ratchet mechanism the disk may be rotated to bring them to the correct height for it is obvious that the slot 5 11 in the disk 9 holds the member 3 against rotation and therefore when the disk is r0- tated the member 3 is also rotated and a portion of the shade is rolled onto or off of the roller. The ears 8 hold the disk close enough to the bracket so that the projection extends into one of the notches 13 a suflicient distance as to require considerable pressure upon the disk in order to spring the disk and the bracket apart in order that the projection 12 may snap from one notch to the next in order that it may hold the disk 10 against rotation at any stage of rotation that attains the desired adjustment.
In Figs. 6 and 7 the bracket 4 is formed with ears 14 extending outwardly parallel thereto for use in combination with windows having a supporting surface projecting at right angles to the axis of the roller 2.
Although a specific embodiment of the present invention has been illustrated and described it is to be understood that various changes may be made in the details of con struction without departing from the spirit of the invention as defined in the following claims, and such changes are contemplated.
What I claim is:
1. A device of the character described comprising a bracket having a dome shaped pro jecting portion with an opening formed therein, an angular projection formed on said bracket, a disk having a slotted dished portion fitting said dome shaped projection, and notches formed in said disk adapted to receive said angular projection.
2. A device of the character described comprising a bracket having a dome shaped projecting portion with an opening formed therein, an angular projection formed on said bracket, a disk having a slotted dished portion fitting said dome shaped projection, notches formed in said disk adapted to receive said angular projection, and ears formed on said bracket and bent over said disk to hold the latter so that said angular projection extends into one of said notches.
3. A device of the character described comprising a bracket, a dome shaped projection formed on said bracket and having an opening therein, a disk having a dished portion fitting over said dome shaped projection, a slot formed in said disk, and ratchet means for preventing rotation of said disk relative to said bracket.
4. A device of the character described comprising a bracket, a dome shaped projection formed on said bracket and having an opening therein, a disk having a dished portion fitting over said dome shaped projection, an angular projection formed on said bracket, notches formed in said disk, and ears formed on said bracket and bent over said disk to hold the latter so that said angular projection extends into one of said notches.
5. A device of the character described comprising a bracket, a dome shaped projecting portion formed on said bracket, a key hole slot formed in said dome, a disk having a dished portion received on said dome, a slot formed in said dished portion, an angular projection on said bracket, notches in a the face of said disk, and ears on said bracket bent over said disk and holding the latter so that said angular projection extends into one of said notches. 4
In testimony whereof I afiix my signature.
