3 Claims.

This invention relates to improvements in apparatus for mounting window shades of the type adapted to permit free air circulation above the upper sash as well as below the lower sash without interference by the presence of the. shade.

The sanitary value of such circulation is well known, and it has been heretofore proposed to provide for such circulation by employing dewith such movement; but difliculty has been ex-' perienced in providing effective connection of the brackets assuring avoidance of loosening or accidental disconnection except where detachable bracket constructions have included involved and expensive apparatus.

It is the essential object of the present inven+- tion to so simplify the construction as to reducethe expense of its production to the minimum while at the same time affording an assuredrigid,

sturdy mounting during use, and at the same time enabling quick and easy disconnection of the brackets when and as desired.

With this and further objects in view as will in part hereinafterbecome apparent and in part be stated, the invention includes brackets each of which is formed with a key-hole slot adapted to receive the head portion of a fastener carried by a sash, whereby the bracket is adapted to be readily applied to and removed from such fastener and to be rigidly held by the fastener during use against loosening or accidental removal.

The invention in greater detail comprises such a bracket in which the slot is shaped and located to avoid loosening or accidental detachment; and in greater detail a preferred embodiment of the slot includes a bayonet portion whereby movement of the bracket angularly to cause relative movement about an angle in the slot is necessary to effective mounting or demounting.

The invention still further comprises certain other novel constructions, combinations, and arrangements of parts as will be hereinafter specified and claimed.

In the accompanying drawing,- Figure 1 is a view of a window provided with an embodiment of the present invention.

Figure 2 is a view inside elevation of one of the shade brackets detached.

Figure 3 is a fragmentary view of the other shade bracket making a pair with the bracket seen in Figure 2.

Figure 4 is an edge view of the bracket seen in Figure 2. H

Figure 5 is a transverse section taken on the plane indicated by line 5-5 of Figure 2, and looking in the direction of the arrow, a part being seen in elevation.

Figures 6, 7, and 8 are all views similar to Figure 5 of further modified forms of the footportion of the bracket.

Figure 9 is a side elevation similar to Figure 2 of a fragment of a bracket having the foot set at an incline to the planes of the main body of the bracket. y' i Referring to the drawing'by numerals, 1 indicatesa bracket body having a lateral outstanding foot 2. The outer or free end portion of the body 1 is provided with a slot 3 or with an ape"r ture 4 according to which end of the roller is to be received bythe particular bracket. 'It is, of course, well understood that the slot 3 receives the flattened end of the windingshank of the usual shade roller, while the aperture e1 forms the bearing for the journal or shank of the other" end ofthe roller. The slot 3 is preferably pro-- vided with an offset 5 torestrain the winding shank from escape on a sudden winding up of the roller or other unintentional movement thereof. The inclination of the slot 3 also aids in preserving the shank against accidental release. An ofiset 6 is preferably formed in the length 90. of each bracket 1 to provide space for the free accommodation of the sash cords of the lower sash while enabling the outer portion of the respective bracket to lie as snug to the window casing as may be desired. Of course, each brack- 95 et 1 is preferably of a length sumcient to outstand beyond the window frame, or at least to outstand far enough to allow the shade to play freely up and down past the lower sash.

The foot 2 is provided preferably with two 100 slots, each adapted to receive a fastener anchored to the upper portion of the upper sash, and while the slots are susceptible of a variation in contour they are preferably constructed to avoid accidental detachment, and, to that end, each of the 5 slots is preferably in the form of a key-hole slot 7, and each is also preferably provided with a bayonet slot terminal 8 extending at an angle to the main body of the slot. The enlarged end 9 of each slot making it a key-hole slot is of sufg ficient size to readily pass over the head of the fastener 10 carried by the sash. The fastener 10 may be any appropriate anchorage device, such as a tack, nail or screw sufficiently effective- 5-- ly connected to the sash to insure against loosening or separation therefrom. The head of the fastener 10 outstands slightly from the sash to snugly accommodate the foot 2 between the sash and the head. The two fasteners 10, where two slots '7 are employed, are spaced to correspond exactly with the spacing of the slots, so that the bracket may be readily applied by merely moving the foot into alinement with the heads of the fasteners relative to the openings 9 pressing the foot across the said heads and then moving the foot laterally so that the heads move relatively into the slots '7, and this movement is continued until the foot comes to rest with the fasteners located in the bayonet portions 8 of the slot. Thus, the bracket is readily, easily, and quickly applied, and yet is firmly seated so as to resist loosening and to resist accidental detachment.

Other forms of slots may be employed, such, for example, as seen in Figure 6, where the angular portion or bayonet part 8' is turned downward instead of upward. Likewise, as seen in Figure 7, the bayonet portions of the slots may be omitted when the slots assume the form seen at 7' in Figure 7 with their enlarged ends downward. In Figure 8 simple key-hole slots 11, 11, are shown in lieu of the slots 7, and these have the advantage of simplicity of construction, application, and removal, but are not as effective in resisting accidental disconnection as are the slots 7.

In operation, the brackets are applied as just above described, and then the shade roller is inserted in the usual manner and functions the same as with ordinary brackets except for the movement of the shade roller up and down with the upper sash. Should it become desirable to move the two sashes past each other, as when the Windows are being washed, the roller is removed a from the brackets and the brackets are then free to be shifted as required to release the engagement of the fasteners 10 from the slots; but it will be readily apparent that so long as the roller remains in engagement with the brackets it prevents bodily movement of the brackets toward each other, and, therefore, prevents the movement necessary to release the brackets from the fasteners 10. Accordingly, the mounting is rigid and dependable while readily demountable as and when required.

It should be understood, of course, that the fasteners 10 have their heads spaced from the surface of the window-frame or stile sufficiently to snugly accommodate the bracket foot between the head and said surface. A screw is preferred as the fastener 10, because a slight turn can be given to it when and if desired after the foot has been applied to insure greater tightness and snugness of fit, and a similar fractional turn can be used to slightly loosen the engagement just before the foot is to be moved to bring the enlarged ends of the slots into register with the heads of the fasteners.

The bracket is preferably stiffened, as by fillets in the angle between the body of the bracket and its foot, and such fillets may be effectively provided by cross stamping the said angle, as at 12, 12.

What is claimed is:

1. A shade bracket comprising a body and a foot, the foot being formed with a plurality of key-hole slots.

2. A shade bracket for use on a window sash comprising a body and a foot extending laterally from the body in the direction to project toward the opposite side of the sash from the side at which it is located, and a key-hole slot in the foot with the enlarged end of the slot nearer the body of the bracket and the reduced, elongated portion of the slot extending away from the bracket, whereby when the bracket is in engagement with a fastener extending through the elongated portion of the slot the bracket must be moved in a direction across the sash to bring the enlargement of the slot into register with the engaged fastener, and the slot having a portion extending at an angle to the main body portion of the slot.

3. A shade bracket comprising a body and a foot, the foot being formed with a plurality of key-hole slots, and each slot having an end portion extending at an angle to the'main body of the slot.
