Z0722 Z 7 I aw Patented Dec. 1, 1931 UNITED STATES THEODORE r. LALLANCE, or Hemmer, wEs'r mama i SCREEN HARD AR Application filed June 6, 1929. Serial No. 368,945.

This invention aims to provide a simple device for suspending screen frames from a window casing, the construction being such that it will be unnecessary to mortise the window casing or the screen frame, and'it being possible to accommodate screen frames of different width and thicknesses. Another object of the invention is to provide a device of the class described wherein the suspension members may be mounted on the stiles of the window-casing from the inside of the window, thereby rendering ladder work unnecessarv.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains. With the foregoing and other objects in view, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the device hereindisclosed, within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings: Figure 1 shows in front elevation, a windew and screen frame equipped with the device forming the subject matter of this application;

Figure 2 is a vertical section on the line 22 of Figure 1; i

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a fragmental elevation showing a portion of a window casing and screen frame equipped with the device forming the subject matter of this application, but ina modified form; and

Figure 5 is a vertical section of the structure shown in Figure 4.

Referring to Figures 1, 2 and 3, there is provided a suspension member 5 comprising a thin, flat metal plate 6 provided with a hook.

8, all portions of the plate and the hookbeing in a common plane, the plate and the book being of a common thickness throughout. A hanger 9 isprovided, and is likewise made of thin metal having a common thickness throughout. The hanger 9 includes a base 10, and outer flange 11, and a web 12 connect- .ing the base to the flange, the base and the flange-being parallel and located at right angles to the suspension member 5. Thebase 10 and the flange 11 of the'hanger 9 project in opposite direction fromoppositeedges of web 12, asFigure 3 shows. The flange. 11

has an opening 15 in which the hook"8 ofv the suspension member 5 is received, the

opening 15 being elongated in a direction at right angles'to the plane in which the suspension member 5 ls'located. 7 The numeral 1 marks a window casing in- .cludingstilesfi' and a lintel 3. The numeral Atmarks' a frame of a screen or other closure.

The suspension members '5 are secured against the stiles 2, in abutment with the lintell), by means of securing elements 7, such Screws 11,'or other securing elements, are used to attach the base 10 of the hangers 9 of the screen frame 4 at its upper corners. Because the suspension members 5 are thin and of a common thickness throughout, they can be'placed readily between the screen frame 4 and the stiles 2 without mortising either the'screen frame or the stiles, a feature which will be understood readily when Figure 3 is noted; =Moreover, because the suspension members 5 can be mounted on the stiles 2, as shown in Figures 3 and 2, they can be put up from the. inside of the house, and it is not necessary to'do any ladder work or for the operator-to assume a dangerous position when attempting to put up the sus- 35 pension members from the inside of the house, a feature which will be understood readily by anyone who has attempted to erect screens in a building. There are no rights or lefts in the structure. a

In Figures 4: and 5, the window casing is marked by the numeral 16, and includes stiles 17 and a lintel 18. The screen frame is marked by the numeral 19. In this form of the invention, the hanger is placed vertically on the screen frame 19, instead of horizontally, as in Figures 1. and 3. The base 20 of the hangeris secured by means of screws 21 to the screen frame 19, the web 22 extends down- Wardly and'the outer flange 23 extendsupwardly, the flange having a horizontal elongated opening 24 through which the suspension member 25 passes, the suspension mem- 'ber 25 being attached by screws 26 to the 5 under surface of the lintel 18. The suspension member 25 is turned at its end to form an 7 upwardly projecting hook 27 that retains the 7 hangerpivotally, in a way which will be readily understood. The suspension meml ber 25 is formed of thin metal of a coin mon V I 1 thickness throughout.

The device is simple, and can be manning: 5 tured at the cost of a few cents. It afiords suspension means for screens which'acan be v put up from the inside of a house without chisel work'or cutting oflany'kind. ,7 Iclaim 7 V A suspension device adapted for use with :a screen, comprising a horizontal suspension I member projecting outwardly beyond a casingvand secured to %the' top of said casing, the suspension member being provided at its outer end with an upwardly-extended, outwardly-convexed hook, the upper end of which extends backwardly in overhanging relation to the :base ofthe hookfa hanger including a base secured to the upper portion of a screen, a web projecting outwardly from the base, and a vertical, upwardly-extended flange at the outer end of the web, the flange having an opening receiving the suspension member, the hook lyingin front of the iflange, -with the upper end of the hook so close to the/upper end ofthe flange that the upper 345 end of the screen can-have no appreciable out- J ward movement until the lower end of the screen is swung outwardly to carry the flange .backwardly with respect to thenpper end i of :the .hook, the-web slanting downwardly i0 and outwardly, whereby when the screen is 1 disposed'at an acute angle to the casing, during the mounting of the flange on the hook, backwardcpressure on thescreen :will cause the web to slide downwardly on the convexed 7 partof the hookand cause theupper end of the hook toenter the opening in the flange. In testimony that I claim the foregoing as my own, I have hereto aflixed vmy signature.
