Claims.

This invention relates to a window guard mounted on a roller above a window opening and adapted to operate automatically so as to be lower'ed when it rains, to protect a window opening from the rain, and to be automatically raised when the rain stops.

My prior United States Patent No. 2,103,923, granted December 28, 1937, covered an apparatus adapted to serve this purpose and in that construction the weight of rain water, collected in a trough attached to the guard or awning, caused the latter to descend when the rain started, and a counterweight was provided to roll up the guard when the rain stopped.

One object of the present invention is to provide an improved mechanism whereby the guard is caused to unroll and descend automatically by the operation of a permanent weight and whereby the raising of the guard, after the rain stops, is effected by the weight of rain water automatically supplied from a storage tank.

- A further object is to provide means whereby even a very slight rainfall is suificient to cause the mechanism to operate'and lower the guard, and, when the rain has entirely ceased, the weight of rain water supplied from the reserve tank is sufficient to raise the guard against the action of the lowering weight.

Still another object of the invention is to provide means whereby the guard is retained in its raised position by a cam or lug engaged by a pawl, against the action of the lowering weight, and to provide means whereby the pawl automatically releases the cam'when the rain starts.

With the above and other objects in view, the present invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes may be made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawings, Fig. 1 is a front viewp artly in sectionshowing the actuating mechanism, Fig, 2 is a plan view thereof shown partly in section, Fig. 3 is a view corresponding to Fig. 1 but showing the parts of the mechanism in different positions, Fig. ,4 is a detail cross-section taken on the line 4-4 of Fig. 1, Fig. 5 is a sectional plan view taken on the line 55 of Fig. 1, Fig. 6 is a front view of a window with the improved guard applied thereto, Fig. 7 is a side view showing the guard inusetas an awning, and Fig. 8 is a detail sectional plan showing certain parts for use with awning.

:Referring to the drawings, an automatic guard in ofwaterproof fabric or other suitable flexible material or combination of materials is mounted ona roller l I outside and above, a Window 12, and

mechanism is provided whereby the guard is lowered when it rains and is automatically rolled up after the rain stops. The roller II and the operating mechanism are mounted in a casing l3 supported above, or at the top of the window opening M (Fig. 6) and this casing is provided with a top cover l5 having a depression I6 with an opening 11 at its lowest point for the passage of rain water, and a strainer 18 is provided to exclude leaves and other solid matter from the opening I1. Arranged below the opening I1 is a cup l9 forming part of a tube 20 pivoted at 2| and containing a ball weight 22 by which the cup I9 is normally held in its raised position as shown at Fig. 1. When rain water from the opening l1 accumulates in the cup 19, the tube member 20 turns clockwise until the ball 22 is caused to roll by gravity towards the right and the ball then engages and operates a lever arm 23. the end of which extends upwardly through a slot 24 in the bottom of the tube 20. The lever 23 is pivotally mounted on trunnions 64 (see Fig. 5) and has a pointed projection 25 engaging a central depression in a disc 26 having in its opposite side an annular depression for the reception of the compression spring 21 whose opposite end engages a similar disc 28 which latter is engaged by an adjustable screw 29 by means of which the compression of the spring 21 may be regulated. The lever 23 and spring 21 are normally in a straight line but when the lever 23 is thrown downwardly by the momentum of the ball 22 the spring 21 is free to expand upwardly and an extension arm 30 forming part of the lever 23 then moves upwardly (Fig. 4) and raises an arm 31 which is pivoted at 44 and has thereon a projecting pawl 32 which releases an inclined projection 33 on the periphery of a pulley 35 attached to the shaft 42 of the roller ll so that the pulley and roller rotate in unison, and as the pulley and roller are thus released, a weighted strip 34 on the lower edge of the flexible guard It! then rotates the roller 1 I and thus pulls down the guard.

As the guard I0 is thus lowered by the weight 34 the rain water passing through the hole I1 to the cup 19 flows from such cup to a lower cup 45 mounted on a lever arm 46 pivoted at 41 and having a counterweight 48 and as the cup 45 re,- ceives water from the cup H! the arm 46 turns clockwise with the lowering of the cup 45 and excess water from cup 45 flows into a reserve tank 49 of substantial capacity. The cup 45 is provided with a small aperture 50 through which the rain water may slowly seep, so that the weight of the water in the cup 45 holds thesaid cup in its lowered position until the rain stops falling and until the water in the cup has sufficient time to seep slowly through the said aperture 50. In the case of uneven rain, therefore, the cup 45 will not swing up and down. As long as the rain continues to fall, the cup & remains in its lowered position as shoWn in full lines at Fig. 3 and, when the water in the reserve tank 49 reaches its highest level, excess water escapes by a suitable overflow-not shown-and when the rain stops falling and the cup d5 has had sufficient time to discharge its contents the lever 45 is swung upwardly by the counterweight 48 and the arm 46 thus releases a pin 51 on a pivoted member 52 so that the latter is free to turn counter-clockwise by gravity and thus move from the position shown in full lines to that shown in dotted lines at Fig. 3, thereby permitting a flexible hose 53 to swing downwardly by gravity and to allow water to pass from the reserve tank 69 to a channel 54 from which the Water passes to a vessel 38 as hereinafter described.

The member 52 is mounted on a pivot pin 59 and on one end thereof the projecting pin 5! is provided for engagement by the arm 56 and on the opposite end of the member 52 rings or loops 62 are provided for the reception of a pipe 63 capable of free sliding movement therein. The pipe 63 is connected with the lower part of the reserve tank ti? by the said flexible hose 53 so that rain water may flow from the said tank to the hose 53 and the pipe 63 when the latter is in its lowered position as shown in dotted lines at Fig. 3.

T raise the guard It, the said pulley 35 has wound thereon a cable 56 which is shown extend ing over a guide pulley d3 (Fig. 4) and extends downwardly and is accommodated in a vertical tube 3! and carries on its free end the opentopped Vessel 38 above referred to. The cable 36 is wound on the pulley 35 in the opposite direction to the winding of the guard on its roller ll so that, when rain water is supplied to the vessel 38, and the weight thereof overbalances the weight 3 5 on the guard ill, the vessel 33 descends and causes the weight 34 to ascend thereby rolling up the guard. The vessel 33 is provided with a spring-loaded valve 39, the stem M! of which projects downwardly and is engaged by a stationary member M when the vessel 38 reaches its lowest position so that the valve 39 is then opened and the rain water is discharged from the vessel 38 and, while the guard is held in the raised position by the action of the pawl 32 as above described, the vessel 38 remains in its lowered position even after the discharge of the rain water therefrom.

The weight 34 on the guard. it? is provided with a projecting bracket 55 and when the guard is raised this bracket en ages and raises a reset lever 5% which is pivoted at El and has a projecting member 58 for turning the member 52 in a clockwise direction about its pivot 59, has a projecting part 59 for raising the arm 23 until the spring 21 is brought to its compressed and balanced position, and has a top part 6! for raising the tube 20 until the ball weight 22 rolls to the left hand end of the tube 28 and thereby holds the cup IS in a raised position.

The projecting cam 33 on the pulley 35 is so located that when the guard reaches the uppermost position the cam is spaced about one inch from the pawl 32 and after the water is allowed to escape from the vessel 38 by the action of the valve 39 the weight 3 3 causes the guard to move slightly downwards until the cam 33 is engaged by the pawl 32 and the reset bracket 56 thus moves downward by gravity from its top position and frees the tube 20 and the arm 23 in readiness for the next operation, but does not allow the member 52 to turn far enough to bring the outlet end of the pipe 63 below the level of the water in the reserve tank 49. When the automatic lowering of the guard causes the projection 58 to entirely release the member 52, however, the arm 46 engages the projection 5| thereby preventing flow of water from the reserve tank 19 to the vessel 38 until the next time the guard is to be raised.

The reserve tank 49 preferably has sufficient capacity for several operations of the guard and by this arrangement the mechanism may operate effectively several times even though the rainfall is very light each time.

A cord 65 may be attached to the vessel 38 and may pass therefrom to the weight 34, being passed through a suitable aperture 66 in the tube enclosing the container and cable 36, and this cord 65 may thus serve as a suitable means for actuating the screen by hand if and when desired.

Referring particularly to Figs. '7 and 8, the side edges of the guard 10 may be accommodated, when the guard is in its lowered position, in side channels each comprising a rear fixed strip 13 and a hinged front strip 61, which latter may be turned outwardly through degrees (as shown in dotted lines at Fig. 8) to permit the guard I0 to be swung outwardly into the position shown in Fig. '7 and shown in dotted lines at Fig. 8 so as to serve as an awning, and, to retain the guard in this position, an arm 68 is secured to the strip 61 and may have a hook 69 on its outer end for engagement with an eye 19 secured at the lower edge of the guard Ill. The guard I0 is moved outward into position for use as an awning and the hook 59 is engaged with the eye 10 by hand, and when it is desired to return the awning to its vertical position for use as a guard, the hook is disengaged from the eye .10 and the strip 61 is returned to the position shown in full lines at Fig. 8 where the strips 67 serve as guide for the side edges of the guard I0 during the upward and downward movement thereof.

As shown at Fig. 8, the channels for the side edges of the guard may also comprise inner strips ll parallel to and spaced from the strips 13 to provide channels to serve as guides for the marginal edges of wire mesh or mosquito netting I2.

Although the drawings and the above specification disclose the best mode in which I havecontemplated embodying my invention, I desire to be in no way limited to the details of such disclosure, for in the further practical application of my invention many changes in constructional details may be made as circumstances require or experience suggests, without departing from the spirit of the invention within the scope of the appended claims.
