Specification of Letters Patent. Q Patented May 16 1916,

Application filed March 9, 1914. Serial No. 823,336.

To all whom it may concern:

Be it known that I, EDWARD C. PFAN- SCHMIDT, a citizen of the United States, and a resident of the cit of Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Awnings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

The general objection to awnings in which the fabric is secured to stationary retaining means along the edge at the top of the window, and with its other end secured to an adjusting bar, has been that the awning is more or less unsightly when pulled into position out of use, owing to the sagging of the loose fabric, and the awning is also subjected more or less to the action of the wind which may tear the same. Awnings have been used wherein the fabric has been rolled up upon a roller to practically conceal the awning when in a position out of use, but generally in this type of awning the brace rods have only been capable of holding the awning in one certain adjusted position and intermediate adjustments cannot be at tained.

This invention relates to an awning equipped with a roller upon which the fabric may be rolled into a position out of use and practically concealed from view, and wherein interlocking adjustment plates and brace rods are provided in order that the awning may be lowered into any one of a number of positions to suit the requirements and con venience of the operator, and in all such positions of the awning the interlocking mechanism serves to hold the awning rigidly in position.

It is an object of this invention to construct an awning provided with a roller to receive the fabric wound thereon and with brace rods slidably mounted in guides for the purpose at the side of the window frame and with locking means positioned to limit the movement thereof, whereby the awning may be held in various adjusted positions and incapable of movement except when manually released by an operator.

It is also an object of this invention .to construct an awning wherein the brace rods are slidably mounted in the window frame and with fixed adjusting plates having a plurality of notches or projections to coact with the brace rods, permitting the awning to be set rigidly in any desired adjusted position.

It is also an object of this invention to construct an awning wherein the fabric is wound upon a roller to which brace rods are attached to co-act with interlocking mechanisms secured upon the frame of the window to hold the awning rigidly in position when tension is imposed upon the fabric by a reverse rotation of the roller with the awning in lowered position.

It is also an object of this invention to construct an awning wherein the brace rods are adjustable, adapting the same to different widths of windows, and wherein cam mechanisms are provided to telescope one of said brace rods when the awning is retracted to permit rolling of the brace rod on the roller with the. fabric.

It is also an object of this invention to construct an awning wherein the fabric is rolled upon a roller and brace rods are mounted at the outer end of the fabric to extendv the same away from the window, and with which a telescoping brace rod is associated to hold a certain portion of the fabric close to the window when the awning is eX- tended, and with means for telescoping said brace rod to permit the samebeing rolled upon the roller when the awning is retracted out of use.

It is also an object of this invention to construct an awning wherein a telescoping brace rod co-acting with cam surfaces, may

*be reduced in length to be wound upon the roller receiving the fabric of the awning when the awning is retracted and wherein interlocking mechanism for certain other brace bars is provided to rigidly hold the awning extended in front of the window at any desired position of adjustment.

It is also an object of this invention to construct an awning wherein the fabric is received upon a roller, with bracket arms and brace bars connected to the fabric to extend the same away from the window, and with another brace rod mounted in the fabric to hold a certain part thereof inwardly in the plane of the window frame, and with guide rods and adjustment plates mounted upon the window frame, adapted to coact with said brace rods to guide the same in their movement and hold the same in bracing position.

It is a further object of this invention to construct an awning wherein bracket arms are secured to the fabric to extend the same in front of a window and with auxiliary bracing bars pivotally mounted to said arms and acting when the fabric is tensioned, to hold said first mentioned brace rods rigidly and outwardly from the window frame.

It is also an object of this invention to con struct a device wherein a spring actuated telescoping bracing rod is associated with the fabric and coacts with cams mounted. upon the window frame, which telescope said bracing rod when the awning is retracted, permitting the rod to he wound upon a roller with the fabric, and with guide rods mounted upon the window frame engaged by said brace red.

It is a further object of this invention to construct a roller awning wherein the awning is lowered and extended int-o position for use by gravity and the parts are rigidly braced in such position by reversing the retation of the rollers to adjust the parts of the awning rigidly in any position desired, and wherein the awning is retracted by releasing the tension upon the fabric and permitting the brace rods to swing clear of the interlocking mechanism to be elevated together with the fabric into position out of use.

It is finally an object of this invention to construct an awning consisting of few parts acting effectually to permit adjustment of the device into various positions whereby in each position the awning is held in place by forces opposed to one another.

The invention. (in a preferred form) is hereinafter described, and more fully pointed out and defined in the appended claims.

On the drawings: Figure 1 is a perspec tive view of a window equipped with an awning embodying the principles of my invention. Fig. 2 is a fragmentary exterior view of the upper end of the window frame with the awning mechanism secured thereon. Fig. 3 is a similar view of one side of the window frame. Fig. 1- is a fragmentary sectional view taken on line ii of Fig. 3, with the roller and fabric omitted. Fig. 5 is a side elevation of the parts shown in position when the awning is being lowered for use, and with dotted lines illustrating the movement of the parts to and into an adjusted position. Fig. 6 is a fragmentary section taken on line 66 of Fig. 5. Fig. 7 is a fragmentary section taken on line 7-7 of Fig. 4. Fig. 8 is an enlarged detail view of one of the combined cam and bracket plates supporting the roller and the upper end of the guide rods. Fig. 9 is a longitudinal central section taken through a spring impelled telescoping brace rod. Fig. 10 is a top plan view of the extensible bracket secured to the lower end of the awning fabric.

As shown in the drawings: the walls of a building are denoted by the reference numeral. 1, and secured in a window aperture therein is a sash frame 2. At one side and at the top of said frame, a bracket plate is mounted, the base 3, of which is held tightly against the outer surface of the frame by means of screws 4. An integral flange or web 5, extends outwardly substantially at right angles to said base portion and is slotted in the manner shown at 6, to receive detachably journaled therein the gudgeon 7, of a roller 8. At its other end said roller 8, is provided with an extended gudgeon 9, and a small pulley or sheave 10, is rigidly secured thereon to receive an actuating rope or cord 11, therearound. The gudgeon 9, of the roller 8, projects through an aperture in a flange 12, on another bracket plate, the base of which is denoted by the reference numeral 13, and is held in position on the window frame by screws 14. Each of said brackets is provided with an inclined flange or cam surface 15, projecting outwardly in a plane sub stantially at right angles to the respective base portions and furthermore, apertured lugs 16, are formedon each of said bracket plates to receive the upper end of guide rods 17 therein, said guide rods extending longitudinally of the window sash subfiantially in a vertical position. Said inclined flanges or webs 15, act as cams for a purpose hereinafter described and at their upper ends terminate flush with flange members 18, on said roller 8.

The awning fabric is designated by the reference numeral 19, and one end thereof is secured upon the roller 8, which, when the awning is in retracted position, is adapted to receive the fabric wound thereon, together with an intermediate telescoping brace rod attached to the awning fabric. The telescoping intermediate brace rod consists of tubular members 20, which are held rigidly in a certain adjusted position dependent upon the width of the window by a central sleeve 21. Each of said tubular members 20, contains a rod 22, slidable therein with a lug or stop 23, thereon, engaging in a slot 24-, in said tubular members 20, which limits the movement of said slidable rods. Spiral compression springs 25, are contained within said tubular members 20, acting normally to impel said slidable rods 22, outwardly therefrom. A roller 26, is journaled in the outer end of each of said slidable rods, so that when the awning is drawn upwardly into a position out of use, each one of said rollers 26, tracks over the inclined portions 15, of the bracket plate on the window frame, thrusting the rods 22, into the tubular members 20, until said intermediate brace rod is shortened to a length permitting the same to be wound upon the roller 8, between the flanges 18, thereof, together with the fabric. Said intermediate brace rod, when it moves upwardly and downwardly with the awning fabric, travels behind said guide rods 17, thus holding that portion of the awning fabric between the intermediate brace rods and the roller substantially vertically or in the plane of the window frame. A pair of slotted bars 27, are adjustably connected by set screws 28, and inserted through a hem on the lower end of the awning fabric, and rigidly secured to the ends of said bars 27, are bracket arms 29. Sleeves 30, are slidably mounted ipon each of the guide rods 17, and each of said sleeves is provided with an integral pin extension 31, on which; said bracket arms 29, are pivotally mounted and held from detachment by means of a split pin 32. Said guide rods 17 are supported at their lower ends on the window frame by means of brackets 33, which serve as a stop to limit the movement of the sleeves 30, as the bracket arms are lowered.

Pivoted on the bracket arms 29, are brace rods 34-, on the inner ends of which are integral gudgeon members 35, provided with. enlarged or flanged heads 36, for a purpose hereinafter pointed out. Grooved adjustment plates 37, are rigidly secured on each side of the lower end of the window frame below and substantially in alinement with the guide rods 17 and flared outwardly at their upper ends to receive the enlarged ends 36, of the gudgeons on the ends of the brace rods 34:, when the awning islowered. Each of said adjustment plates is provided with a plurality of projections or teeth 38, which act to resist an upward movement of the gudgeon heads 36, but readily permit the same to travel downwardly therethrough. At its lower end each of said adjustment plates is provided with an integral inverted Y-shaped retaining member 39, directly below which the walls of said adjustment plate are cut away, and a small lug or projection 40, directed upwardly toward said Y-shaped member, is formed on the lower end of the adjustment plate to direct the gudgeon head 36, toward said Y-shaped member when the gudgeon has been lowered its entire amount and is then elevated a slight amount.

The operation is as follows: Assuming the awning to be retracted into position out of use, and it being desired to lower the same, the adjusting cord 11, is actuated or released to permit the fabric to be drawn downwardly by gravity, due to the weight of the bracket arms and brace rods secured to the end thereof. The bracket arms 29, travel downwardly until the sleeves 30, contact with the supporting brackets 33, for the guide rods 17, and at this instant the lower end of the brace rods 34, are in a position such that the heads on the gudgeons have entered the upper ends of the adjustment plates 37. The bracket arms 29, upon being checked in their downwardmovement by the brackets 33, swing outwardlyupon the pivots 31, and the brace bars 3t, pivotally connected thereto move therewith, the lower ends of said brace bars traveling down- Wardly in the adjustment plates. If it is desired to maintain the awning in a certain adjusted position, determined by theangle the bracket arms 29, make with the window frame, the roll is reversed in its movement by means of the actuating cord 11. This tends to: elevate the bracket arms by tension on the awning fabric, and causes a consequent elevation of the lower end of the brace rods, the gudgeon heads 36, of which engage behind one of the projections 38, preventing a retractive movement thereof, thus bracing the entire mechanism in an adjusted position.

The awning inv its position shown in Figs. 1, 3, and 4, is in its lpwest possible position of adjustmentthat is, one in which the gudgeon heads on the ends of the brace rods 34, are engaged in the Y-shaped retaining members 39, at the lower end of the ad justment plates. It is a noticeable feature in this invention that the mechanisms do not assume an interlocking bracing relation with one another until an attempt has been made to reverse the rotation of the roller to draw the elements upwardly, this movement, as pointed out, causing the gudgeon heads on the lower end of the brace rods 3%, to engage one of the retaining members in the adjustment plate, so that the reverse rotation of-the roller is opposed by the bracing bars which, with the fabric, are then under a condition of tension.

through the cut-away portion thereof between the Y-member and the small lug 40. Then, of course, the roller is reversely rotated by the adjusting cords to roll up the fabric, and the gudgeons being entirely disengaged from the adjustment plates, are carried upwardly uponthe bracket arms 29, which first fold inwardly and then slide upwardly upon the guide rods 17. As this operation progresses, the telescopingintermediate brace rod secured to the awning fabric is caused to be shortened in its length, due to the contact with the inclined cam surfaces 15, so that when the intermediate brace rod reaches the roller, it is foreshortened to a length permitting the rod to be wound with the fabric between the flanges 18, on the roller.

It isobvious that any desired adjustment of the awning may be effected by causing the gudgeon heads on the lower end of the tensioned brace rods 34:, to engage behind any one of the projections 38, in the adjustment plates by reversely rotating the roller a slight amount when the desired position in which the awning is to be secured is reached, and, of course, the tension must be maintained upon the adjusting cords by fastening the same upon a suitable cleat secured upon the window frame at any convenient point.

I am aware that various details of the construction may be varied without departing from the principles of this invention. I therefore do not purpose limiting the patent otherwise than necessitated by the prior art.
