My invention relates to a curtain raising and lowering device and has for its principal purpose the provision of a device for raising and lowering curtains in response to the raising and lowering of a window sash. One objectof my invention is to provide a simple and efficient mechanism for accomplishing the above function, which shall be cheap, simple to'manufactur'e, sturdy in construction and eflicient in use. Another ob]ect is the elimination of guiding devices on the window frame. I
Other obj ects'will a-ppearfrom time to time in the course of the specification and claims.
I illustrate my invention more or less diagrammatically'in the accompanying drawings, wherein Y Figure 1 is an elevation of a window illustrating my invention associated therewith;
Figure 2 is a section on the line 2-2 of Figure 1;
Figure 3 is a detail; and V Figure & is a section on the line 4.4 of
Figure 3;
Figure 5 is a view similar to Figure 3 of a variant form of my device; and
Figure 6 is a section on the line 66 of Figure 5.
Like parts are indicated by like symbols throughout the specification and drawings.
Referring to the drawings A indicates any suitable window frame having the upper sash A and the lower sash A with the side members A B indicates any suitable curtain rod or supporting structure from which depends the curtain B having a hem or doubled port1on intermediate top and bottom as at B through which passes the rod B the ends of which are secured to the lifting mechanism below described. It will be observed that the lower edge B of the curtain normally depends to or beneath the window sill A.
Mounted at the upper corners of the sash side members A are the outwardly projecting supports C herein shown as including a generally semi-circular body provided with the laterally extended flanges C which may The curtain is herein shown as 1928. Serial No. 290,478.
Each body or sup ort C is further with a flange or a utment C Pivoted'to each support or body C is a lever D at the outer end of which is secured, 1n any suitable fashion, preferably removably, the rod B. D indicates the pivot or pivot point of the lever D and D the arm of the lever opposite the pivot point from the connection with the rod B. Referring for example to the form indicated in Figures 1 to 4 the lever arm D is provided with a flange or bearing surface D D generally provided indicates a spiral spring which tends to rotate the lever D in a clockwise direction as shown for example in Figure 4. The spring member includes an end D engaging the lever D and an end D engaging the base member C, the body of the spring being coiled about the pivot point of the lever. It will be understood from the construction, as shown in Figures 3 and 4 that the spring D tends normally to hold the lever in upwardly inclined position and the curtain is preferably so adjusted as to have its lower edge thereby raised to or above thelevel ofthe lower edge of the sash. It will beheld in this position when the sash is'raised.
Vhen the sash is lowered the lever D will take the position in which it is shown in dotted line in Figure 4, owing to the engagement of its arm I) with the flange D with an abutment generally indicated as at E, which is positioned on the window frame in such fashion as to engage the lever arm when the sash is lowered. It is preferably so positioned as to depress the outer end of the lever D, and thus the rod B, when the sash is in fully closed position is at the bottom of its downward excursion. Preferably the location of the parts and the length of the curtain is such that at such lowered position of the Referring to the form shown in Figures 50 be screwed or bolted to the window frame. 5 and 6 I indicate a body member G corre sponding to the member C of the earlier views. This member G'is provided with two limiting abutments as at G G A lever H is pivoted as at H to the body member G and is provided with a flange or abutment H corresponding to the flange D of the earlier form. Referring to Figure 6, when the sash 'is in the lowest position the lever takes its dotted line position owing to the engagement of theabutment H with the opposed abutment E on the window frame.
full line position; by the action of the coil spring H which is compressed between an abutment H on the body G and an abutment H on the pin or'plunger H? which is pivoted or secured to an abutment H on the short arm of the lever H. The pin H which serves as a guide for the springH passesthrough an aperture H in the abutment II.
It will be understood that as to'both forms of the device that the yielding means are employed normally to hold thecurt-ain sup porting levers in raised position, but that these yielding means are overcome by the engagement of the short arms of the levers with the abutments E fixed on the window frames at the sides of "the sash. \Vhen the sash is lowered it causes the levers to engage the said abutments just prior to'the termination of the downward excursion of the sash and such engagement, in response to further lowering of the sash, rotates the levers, against the springs, into normal downward; position.
It will be realized that whereas I have described and shown a practical and operative device, nevertheless'many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. Itherefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.
