PATENT, FFICE FREDERICK A. ANTON AND EDWIN F. BELL, F TOPEKA, KANSAS, ASSIGNORS T0 TOPEKA Li TENT & AWNING COMPANY, OF TOPEKA, KANSAS, A CORPORATION OF KANSAS WINDOW Application filed April 14,

This invention relates to window awnings of that class provided a visor which may be adjustably positioned anywhere throughout the height of a window opening or which may be used in vertical position as a screen or shade covering the entire height of the window or any fraction thereof, said awning being entirely operable from inside of the building.

A further object of the invention is to provide a construction of the character aforesaid having spring or retractile means which constantly maintain the parts under tension to prevent rattling or vibration of any of the parts, both when the awning is open and when it is in its collapsed or folded condition.

A still further object is to produce an automatic awning of the character outlined having means whereby its operation may be entirely controlled from within a building.

Another object of the invention is to provide a combination supporting bracket and housing forming a hood or protecting housing within which the awning fabric and opera-'-.ing mechanism is entirely encased when the same is in collapsed position to obviate the necessity of removing the awning in winter and at the same time leave no nesting places for birds or the like.

A still further object of the invention is to provide a strong, durable, eflicient, inex pensive and simple construction of the character outlined; and in order that the invention may be fully understood, reference is to be had to the accompanying drawings, in which:

Figure 1 is a fragmentary front elevation of an awning embodying the invention.

Figure 2 is a section on the line IIII of Figure 1.

Figure 3 is a side elevation of the awning frame in folded or collapsed position.

Figure 1 is a perspective view of one of the upper sliding bracket members.

Figure 5 is a view similar to Figure 4, but illustrates the bracket with the upper brace member in operative relation thereto when the fabric is spread to form or provide a visor. I V

In the said drawings, where like reference AWNING 1930. Serial No. 444,118.

characters identify corresponding parts in allof the figures, 1 indicates similar bracket members mounted at the top and on opposite sides of a window opening, said brackets each being of relatively right angle shape, the projecting flanges thereof having opposing grooves in their inner faces for the reception of the ends of a sheet metal hood or housing 2, as shown in Figures 1 and 2, said grooves being so arranged that the front edge of the hood is formed with a return bend 3 to stiffen or reinforce the same against vibration by the wind. Projecting from the brackets 1, are bearing lugs 4, and formed integrally with said brackets at their lower ends are stops 5, all for a purpose which will hereinafter appear.

The opposite ends of a shaft 6'are journaled in the brackets 1, and secured to said shaft is one end of an awning fabric 7, to be wound upon and unwound from the shaft as the awning is respectively raised and lowered. One end of the shaft 6 is equipped with a-gear wheel 8, enmeshed with a worm 9 or other suitable gear, secured to the upper end of a vertically extending guide rod 10, it being evident that upon proper rotation of said guide rod, the awning fabric may be wound upon or unwound from the shaft 6. On the opposite side of the window from the guide rode 10 is a similar non-rotatable guide rod 11, it being evident, however, that the operating mechanism may be located on either side of the window. The rotatable guide rod 10 at its lower end, extends into a bracket 12 secured to the outside face of the conventional casing (not detailed) of the window, and within said bracket the rod is equipped with a bevel gear 13 enmeshed with a bevel gear 14 mounted on a shaft 15 extending through the casing into the building, and having its inner end equipped with a permanent or removable crank 16, whereby the guide rod may be rotated to efiect rolling or unrolling of the awning fabric, as above-described.

Slidingly mounted on rods 10 and 11 are upper and lower brackets 17 and 18 respectively, arranged in pairs and connected by straps or bars 19, the brackets 17 being connected by a cross bar 20 bridging the window opening. The relatively inverted U-shaped frame thus formed is freely slidable from a point where its upper end may contact with the hood, to a point where brackets 18 abut sleeves 21 on rods 10 and 11.

The ends of a relatively U-shaped awning frame 22 are pivoted to brackets 18 that it may swing from the relatively horizontal position shown in Figure 2, to the relatively vertical position shown in Figure 3, it being noted in this connection, however, that the parts are so proportioned that the frame can never swing inwardly past a vertical position as this might lead to the locking of the mechanism in closed position. By preference the parts are so proportioned that the awning frame in closed position, inclines slightly outwardly so that its leverage will always insure opening of the awning when brackets 18 contact with stops or sleeves 21, although it is to be understood that if manually opening of the awning is desired the frame may be permitted to swing inwardly past the vertical, or that, in such a situation springs might be used to give the desired impetus to ensure opening movement.

The awning fabric 7 passes under the cross bar 20 and is securely attached to the cross member of the U-shaped frame 22. Pivoted to the side members of frame 22 are lower brace members 23 having their upper ends pivoted to upper brace members 24, which in turn are pivoted to the upper slide brackets 17 of the inverted sliding U-frame, said brackets 17 being provided with stop members 25 to prevent the break-joint brace from swinging inwardly beyond a line passing through their centers as this would provide lost motion in the parts. The upper breakjoint brace members 24 are provided with'a pair of projecting lugs 26 and 27, the lower most lug 26 upon upward movement of the awning coming in contact with the stop 5 and effecting outward collapsing or breaking movement of the brace, to cause the uppermost lug 27 to override and rest on the stop 5 (see dotted lines, Figure 2) to prevent downward falling movement of the structure, so that the entire frame will be maintained adjacent the top of the window pending the folding movement of frame 22 to the position shown by Figure 3, it being noted that this adjustment brings the cross-members of the pivoted and slide frames so close together that no visor portion remains, the visor portion being that stretch of the fabric running from its lower extremity to the cross-member 20.

In order to provide means for holding the movable parts of the awning frame against vibration, it has been found desirable to so construct the pivoted ends of the frame 22 as to provide a point of attachment 28 for a retractile spring 29, which point of attachment, when the awning frame is in open position,

be evident that in this type of connection,

the retractile spring 29 is maintaining an upward pull at one side of the pivotal point 30 and a downward push on the other side of such pivotal point, but as the fabric cannot unroll from the roller due to the enmeshed gears, the force of said spring removes lost motion from the parts and prevents rattling and vibration in the wind. It will also be apparent from a consideration of Figure 2, that gusts of wind cannot effect accidental collapse or folding of the awning, as the frame is locked in open position by the brace, assisted by springs 29; and the weight of the structure is such that it requires a considerable pressure to belly out the visor portion 31 of the fabric, and effect lifting of the entire structure.

hen the awning frame is in fully collapsed position as shown in Figure 3, the upper connecting point 30a of the spring 29 has moved to a position inwardly inclined from the vertical as regards the face of the building, the guide bars 10 and 11 and the lower pointof connection 28 of said spring 29, it being evident that in this position the spring tension tends to maintain the awning in collapsed position and to remove slack or lost motion which might allow vibration to be set up by the wind.

When the awning is in this folded position,

by rolling up the fabric it will be apparent that the entire awning frame may be drawn up until the cross bar 20 is against the lower edge of the housing 2, and the spring 29 acts to continue the collapsing movement of the brace member 24 to dispose it wholly outward of the vertical plane of stop 5. When it is desired to open the awning, the operator reversely operates the shaft 6, the entire awning frame structure gravitating downwardly along the guide rods, until the weight of said frame is removed from the fabric by the stops or sleeves 21, and then the weight of the pivoted U- frame overcomes the spring tension until the points of connection of the springs pass center, from which point the springs assist in the unfolding operation, until the pivoted frame is locked by alinement of the breakjoint braces as heretofore stated. After the visor is thus formed, the awning fabric may be rolled up to position the visor at any desired point, and it can only be unlocked by being raised high enough to effect the tripping of the break-j oint brace as above recited.

From the above description, it will be apparent that we have produced a window awning embodying the features of advantage set forth as desirable in the statement of the objects of the invention, and which may be modified in minor particulars without de parting from the principles of construction or from the spirit and scope of the appended claims.
