v gwueniiot Patented Nov. 5, 1929 NORVAL MERRITT FAULDS, F cLEABwATERpFLoRlbA DEVICE FOR PQRCH CURTAINS Application filed April 25,

This invention relates to'porch curtains and movable mountings therefor.

It is an object of this invention to provide a porch curtain which may be associated with screen frames and the like, the said invention being effective to hold a curtain for movement with respect to a screen, frame, or the like, associated with operative means for raising and lowering the curtain and for holding the same in different positions of adjustment.

t is furthermore an object of this invention to produce a curtain operating device, associated with novel operative means whose movement is proportional to the movement of the curtain and which is capable of compensating for the increased or diminished I diameter of the roll and pile with relation to which the curtain moves.

view, the invention consists in the details of construction, and in the arrangement and combination of partsto be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying draw: ings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation of a curtain storing and operating device embodying the invention;

Figure 2 illustrates a perspective view of a fragment of the said device,

Figure 3 illustrates a sectional view of one of the moldings; t

Figure 1 illustrates a similar view of another molding;

Figures 5, 6 and 7 illustrate details of the curtain clamp and parts associated with it;

Figure 8 illustrates a perspective view of a fragment of a sill and parts associated with it;

Figure 9 illustrates a detail view of the curtain operating mechanism;

Figure 10 illustrates a bearing guide for crank handle; 7

Figure 11 illustrates the two bearings for 50 both ends of the roller;

I 5 and 6 and the plates are clamped together l/Vith the foregoing and other'objects in 1927. Serial No. 186,295.

Figure, 12 illustrates a roller; and I Figure 13 illustrates a clamp for holding the curtain on the roller. r

In these drawings, 1 denotes a spiral: groove for an operating cord or flexible elementwhich is wound on the roller 3, whereby the said roller is turned to wind and unwind the curtain 4 therefrom. The curtain has a clamp at its lower edge between plates:

by elements41,such as screws,;bolts or the like. The plate 5 is associatedwith a clip 26 that engages the flange 25 of the mold-: ing 16 when the curtain is lowered, andthis effects a water-tight joint which will prevent rain from entering the guarded structure between the curtain and the" said moldlng."

' The molding 15 isformed witha channel to receive the endof'the curtain stick-and the molding acts as a guide, and the joint between the stick and, molding is such as to prevent rain from gaining access to the interior of the guarded structure. p

A cable, cord,'or rope 18 is wound on'the spiral pulley or groove and it is guidedbetween rollers 12 and-13 that are preferably grooved to increase the frictional contact between the flexibleelement and the said rollers in order that when the" said rollers are rotated, the flexible element will be drawn in one or another direction, according to the direction of rotation of the saidrollers.

The roller 12 is associated and rotates with a gear wheel'lO on the core 32 and the gear wheel 10 isin meshwith a gear wheel 11,

sectional view of the which with the roller 13-is associated with a core 83, and the gearing rotates with the roller 13; One part of'the crank 7 extendsthrough or is attached to the roller 13 and the said crank is journaled in a bearing or guide plate 14 and in the frame comprising cheek plates at and 45that are secured together in any appropriate way.

Power may be applied to the crank 7, which has a slot 8, for rotating the core 33 clockwise or anti-clockwise and moving the flexible element in the desired direction. The crank is secured to the core by a pin 3% aoo . extending into the slot 8 of the crank.

tenings.

The flexible element may operate through suitable guides 27 and 28 associated with the plates 44: and 45 and flexible element is also guided over an idler 17 and an idler in a housing 31 at the center of the sill or case with which the curtain is associated, and the said flexible element is, of course, connected to the curtain stick. The curtain is secured to the roller preferably by clips, such as 43, and the curtain is Wound on the roller or unwound therefrom, according-to the direction ofrotation of the. roller. By

reason of the fact that the flexible element is connected to the curtain stick, pull is exerted on the curtain stick when the curtain is to be lowered, whereas when the roller'is rotated in the opposite direction, the curtain will be wound thereon and the flexible element will bev fed toward the curtain and will follow the curtain as it rises.

The roller (has a trunnion at one end which rotates in a bearing plate 38. and at the other end the roller has a plug 35 through which a trunnion 36 extends and the said'trunnion isintended to be seated in the plate '39 having an open bearing with relation to which the trunnion'imay be moved for assembling the" parts or dismantling them. The plug may be secured to the roller in any appropriate way, and the bearing plates 38 and 39 may be secured in place by suit-able fas- The device may operate in conjunction with a window sill or frame comprising suitable parts, suchas 20, 22, 24 and 25 and a screen frame 21, which parts are 'of conventional type and need not, it is thought, he described in detail.

I claim:

In a mounting for porch curtains, a curtain roller, a curtain wound thereon, a conical'pulley for rotating the roller, a flexible element on the said pulley, grooved pulleys between'which the flexible element is held,

shafts on which thepulleys' are mounted, intermeshing gearwheels on the said shafts, means forirotating'one of said shafts, guides for the said flexible element, and means for connecting the flexible element to the free endof the curtain, whereby the flexible element drawsthe curtain from the roller when 7 the flexible element moving mechanism is turning in one direction.
