2 Claims. (Cl. 156-39) This invention relates to new and useful improvements in screens, and it has more specifically for its object to provide an. improved screen casing to be used in connection with windows 5' in order to facilitate the operation of window screens.
As the said device is of a comparatively simple construction, and the costs of materials but small, it is thought that the manufacture and u sale of this invention will meet with a great demand from the general public.
With the above and otherobjects in view, this invention consists of the novel features of construction, combination and arrangement of u parts, hereinafter fully described, claimed and illustrated in the accompanying drawing forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:
gg' Figure 1 shows my device, of which a part is broken away, attached to the frame of a window, that is to the jamb of the said window.
Figure 2 is a detail view of my said device.
Figure 3 shows a casing, forming part of my '.15 device.
Figures 4 and 5 show an endportion of a casing, and an associated part, respectively.
Figure 6 illustrates a roll of screen material with an automatically operating hook-member .J0 attached to the latter, while Figure '7 shows part of a screen partially unfolded in operation.
Referring more particularly to the drawing, 10 indicates a window sash, to which a lug 11 is 5 secured by a screw 12; the said lug 12 is adapted, when` the window is raised, to engage and carry the hook-member 13 along with it in an upward direction; the said hook-member has one end integrally attached to a screen 14, of any suit,- ,mable make as to material, thickness and perforations therein; the said attachment may be accomplished in any convenient manner, as for instance by having the said hook-member formed with split endpicces and having these pressed t5 into the said screen proper. The said screen is wound on a roller 15, of the rather usual kind, and the latter has the usual tension spring associated therewith.
Upon each side of the window :lamb a guide jo' member 16 is attached to the latter 17; the said $6' in; the guide member 16 is attached to the said jamb by means of screws 19. Upon each side the said screen member is formed with a seam 20, as may be seen in Figure 2.
A longitudinally extending metal strip 21, .of a slightly springy nature, is attached by means 00 of its curved end portions, in any convenient manner, to the inner side of one of the guide-walls, as shown at 22, in Figure 1.
The object of the said metal strip is to keep the screen in a taut position during operation, 0B as the said strip slides against the seam of the screen, and at the same time slightly presses the said screen close to the front guide-wall.
The said screen is, when rolled up, and when not in use, enclosed in a casing 23;,the said cas- I9 ing has an opening, as shown at 24, with the adjoining edge-portions of the casing bent to form tubes 25, 26; these tubes are in turn adapted to receive projections 27, 28, formed upon the separate end pieces, as shown in Figure 4, of the said u casing, when the latter is assembled. In order, however, to conveniently remove the said casing and properly adjust the latter, a member, as shown in Figure 5, is attached to the jamb by means of screws inserted into the holes 29 there- 00 of. The said member, shown in Figure 5, and which rests on the window sill, has a cut-out portion 30, and a cut-out and bent lug 31, for the purpose of properly adjusting the said casing 23 relatively to the guide-member 16, and to itself. 95 The latter member is at its top formed with a springy projection, shown at 32 in Figure 5, which. projection is adapted to fit and snap into a depression 33 formed upon the top of of the endportion of the casing, shown in Figure 4, when uniting these parts together. It will be noted that the member 32 is4 shorter than the depression 33, thereby permitting adjustment of the end piece relative to the side plate, the member 31 frictionally holding the end piece in adjusted position. In thus assembling the parts of the said casing, the roller 15 is in turn journaled in endportion of the latter, as shown at 34 in Figure 4.
It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not therefore wish to limit myself to the construction and arrangement m5 shown and described herein.
What I claim as new, and desire to secure by Letters Patent of the United States, is:
1. In combination with an automatically operated window screen, a casing formed with a lill) let being bent upon themselves to form tubes, endpieces adapted to support a shade roller to be mounted upon the casing, said endpieces each being formed with a depression and with projections for engaging the tubes; side-plates secured to a Window frame and adapted to detachably engage said endpieces, the side-plates being formed with means whereby adjustment may be made and maintained relative to the casing of a window, each side-plate having a horizontally projecting lug-member at its top for engaging the endportion of the casing by means of th'e depression in the latter.
2. A Vdevice of the class described, comprising, in combination, a casing formed with a longitudinal outlet therein, the edges of said outlet being bent upon themselves to form tubes, endportions adapted to support a shade roller to be mounted upon the casing, said endportions each being formed with a depression and with projections for engaging said tubes; side-plates secured to a Window frame and adapted to detachably engage the endportions of the casing, the sideplates being formed with means whereby adjustment may be made and maintained relative to the casing of a window, said means comprising a lug laterally arranged upon the side-plates, and a lll
