HARRY T. ADAMS. OF NEW YORK. N. Y.

AWNING-LIFT.

SPECIFICATION forming part of Letters Patent No. 781.983, dated February '7, 1905. Application filed January 25, 1904. Serial No. 190,522.

To [t7] 'whont it many concern:

Be it known that I. H ARRY T. ADAMS. a citizen of the United States. and a resident of the city of New York. borough of Brooklyn, in the county of Kings and State of New York. have invented a new and Improved Awninglaift. of which the following is a full. clear. and exact description.

.\Iy invention relates to awnings. and admits of general use. but is peculiarly adapted for service in connection with awnings of the kind usually lifted at will by hand.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section taken upon the line 1 l of Fig. .2 looking in the direction of the arrow and shows the awning as it would appear to a person within the building and lookingoutward. Fig. 2 is a vertical section upon the line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a fragmentary section somewhat similar to Fig. 2. but showing the awning as raised to its uppermostlimit. Fig. t is a sectional detail showing the springr'oller 1 t and its immediate connections; and Fig. is a fragmentary elevation of one end of the spring-roller, showing the mounting thereof and connections therefor.

The wimlow-frame is shown at 'l and the window-strip at 2. A number of hooks 3 are mounted within the top of the frame and are engaged by rings 4. worked into the front 5 of the awning. The sides 6 of the awning are of the usual construction. The awningframe is shown at T and is preferably of metal. being rigidly mounted upon the movable rods 8*. each provided with an eye 8. engaging an eye 9 on a longitudinal bracketlO of the shape indicated and secured by fastenings 11 upon the window-frame. The pendant or flaps 12 13 of the awning are of the usual form. A

springroller 14: is mounted across the top of the frame in the position shown, and upon it are partially wound a number of tapes 15. the upper or inner ends of these tapes being secured to the roller by means of fastenings 1c and the lower ends being connected with the awning-frame T.

The spring-roller 1 s is provided with a cavity is, in which is mounted a spiral spring 1i" and a pawl 14". these parts being anchored within a ferrule 14:. A flattened stem 14: projects into a slot 2 in the strip 2 and is thereby held against rotation.

The construction of this spring-roller [)m .w' is old and well known. being identical with that heretofore used for awnings. Ahalyard 16 is provided with a ring 17 and is partially wound upon the spring-roller ii in the direction indicated in Fig. 2. A cord lS-is partially wound upon the spring-roller it at the end thereof. as shown at the left in Fig. 1. This cord passes through a pulley or block 19 at the bottom of the window-frame and thence passes angularly outward. so as to connect with the awningframe. as indicated more particularly in Figs. 1 and :2. The purpose. of the pulley or block 19 and of the cord 18. running upon the same. is to hold the awning down. as against the attack of the wind. and this pulley and cord act in conjunction with the roller. so that when the awning is down the cord becomes taut. The window-panes are shown at 20 22. being mounted within the sashes 21 23 in the usual manner. The spiral spring 14: in the roller 1% is wound in such direction that it normally tends to roll up or elevate the tapes 1?). so that the tension exerted by the hand upon the halyard 16 tends to increase the tension of this spring. The awning is raised by the reaction of the spring and is lowered by the hand pulling against the reactive power of the spring.

My invention is used as follows: \Vhen it is desired to lower the awning. the halyard ill or the ring 17 is grasped by the hand and drawn downward. This releases the springroller 1%. which is normally held against rotation. as will be readily understood. in the same manner as the ordinary spring-roller used in supporting window-shades. The halyard being drawn downward causes the eyes 9 to slide vertically downward upon the brackets 10 until they reach the bottoms thereof. whereupon the awning-frame swings outward and downward until it assumes the position indicated in Figs. l and 2. The spring-roller automatically locks against back rotation. and the awning thereupon stays in the position indicated in Figs. 1 and 2. If now it be desired to raise the awning, the halyard 16 or the ring 17 is grasped by the hand and given a slight jerk downward. This releases the spring-roller l t and allows the same under the tension of the spring 1 F to rotate in a contra-clockwise direction, as seen in Fig. 2, thereby winding up the tapes 15 and raising the halyard 16 and the ring 17. lVhen the awning-frame is drawn upward into a substantially vertical position, the tension of the spring being continued, the awning-frame is lifted bodily with reference to the windowframe. the eyes 9 sliding vertically upon the brackets 10 until the awning is completely folded, as indicated in Fig. 3. that in this figure the ring 17 is elevated to a little distance above its position indicated in Fig. 2. The awning is lifted by two successive movements, to wit: The awning-frame is first raised angularly into a position approximately vertical and is then lifted bodily upward, so

as to make the folds shown in the upper portion of Fig. 3. It will also be observed that the awning is self-raising, the power of the hand being partially applied while the awning is being lowered. This enables a person to handle the awning with comparatively little exertion and also lessens the danger of an accident caused by the awning-frame being dropped too suddenly into its lowermost position.

By the arrangement above described a comparatively heavy awning can be safely manipulated by a child.

H aving thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an awning-lift, the combination of an awning-frame, a spring-roller for raising the same, said spring-roller being normally under tension for the purpose, a longitudinal flexible member connected with said awning-frame and with said spring-roller for the purpose of raising said awning-frame by the tension of said roller, a pulley connected with the windew-frame and disposed adjacent to the bottom of the awning, a flexible member connect- It will be noted ed with said awning-frame forthe purpose of normally holding the same down, said flexible member engaging said pulley and passing upward from the same to the awning-roller, and an additional flexible member partially wound upon said awning-roller and manipulated by hand.

2. In an awning-lift, the combination of a pair of longitudinal brackets vertically disposed upon opposite sides of a window-frame, an awning-lift slidably connected with said brackets and adapted to turn angularly with reference thereto, a spring-roller disposed adjacent to the upper part of said window-frame, a canvas connected with said awning-frame and adapted to fold upon itself when said awning-frame is turned angularly, flexible members of longitudinal form extending from said roller to said awning-frame and engaging said canvas so as to pull upward against the folds thereof after said awning frame has been .turned angularly, said flexible members thus raising said awning-frame to a comparatively high point relatively to said spring-roller.

In an awning-lift, the combination of a pair of longitudinal brackets disposed vertically upon opposite sides of a window-frame, an awning-frame connected with said brackets and free to turn angularly and also to move bodily with reference to said brackets, a roller mounted upon said window-frame, flexible members connected with said awning-frame and with said roller, said flexible members being adapt ed to wind around said roller, means for causing said roller to turn, and mechanism connected with said awning-frame and with said roller for normally holding said awningframe in a predetermined position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
