VJINDGW-AWNING.

Application filed April 25,

To all whom it may concern:

Be it known that I, J osnrrr Pononny, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Window-Awnings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window awnings of the type which comprise strip of canvas or other suitable fabric connected at its upper end to a spring roller and at its lower end to the cross piece of an extension member whose side arms are pivotally connected at their inner ends to sleeves which slide on vertically-disposed guide rods secured to the window frame, the upper portion of said strip of fabric being held in a vertical position when the awning is open by means of a transversely-disposed bar or member arranged at approximately the center of the window opening and provided at its ends with sleeves which also slide on said vertically-disposed guide rods.

The object of my present invention is to provide an awning of the general type referred to, in which the vertically-disposed guide rods on which the sleeves of the transversely-disposed bar and the sleeves of the extension member are slidingly mounted are equipped with stops that arrest the downward movement of said transverselydisposed bar, but which have no affect on the vertical sliding movement of the sleeves to which the extension member is pivotally connected, thereby producing a window awning that is inexpensive to manufacture and install.

Figure 1 of the drawings is a front elevational view of a window awning constructed in accordance with my invention Fig. 2 is a vertical sectional view of said awning.

Fig. 3 is a vertical sectional view similar to Fig. 2, but illustrating the transverselydisposed bar and the extension member raised or in the position they occupy when the awning is closed or not in use; and

Fig. 4 is a perspective view, illustrating the operation of the stop on one of the guide rods that arrests the downward movement of the transversely-disposed bar.

Referring to the drawings which illustrate the preferred form of my invention,

Specification of Letters Patent.

1319. Serial No. 292,556.

A designates a strip of canvas or other suitable fabric whose upper end is connected to aspring roller B mounted in brackets .1 on the window frame adjacent the upper end of the window opening, said spring roller being similar to the spring rollers now generally used for window shades and provided with a winding spring (not shown) tlat turns the roller in a direction to wind the fabric A onto same, and locking dogs (not shown) for locking the roller and holding it against rotation. The lower end of the strip of fabric A is connected to the cross piece 2 of a yoke-shaped extension member whose side arms 3 are pivotally connected at their inner ends to sleeves 4 which slide on vertically-disposed guide rods 5 arranged at the sides of the window opening, as shown in Fig. 1. When the awning is lowered or in use, as shown in Figs. 1 and 2, the strip of fabric A passes under a transversely-disposed bar G arranged at the center of the window opening and mounted on the guice rods 5 in such a manner that it will be shifted upwardly into an inoperative position adjacent the upper side of the window opening when the awning is closed, as shown in Fig. 8, said bar C serving to hold the upper portion of the fabric A in a substantially vertical position when the awning is lowered or in use, as shown in Fig. 2. The spring roller B is adapted to be turned in a direction to trip the locking dogs of same or to unwind the fabric A from said roller by means of a tape 6, shown in dotted'lines in 2. If it is desired to raise the awning from its operative position shown in Fig. 2, into its inoperative position shown in Fig. 3 it is only necessary to pull downwardly on the tape 6 sufficiently to trip the locking dogs of the roller B, and thus permit the spring of said roller to rotate the roller in a direction to wind the fabric A onto same. the upward pull that is exerted on said fabric causing the yoke-shaped tension member connected to the lower end of the fabric to swing upwardly on the sleeves 4 and then travel upwardly into the position shown in F 3, the cross piece 2 of said extension member-operating to move the transversely-disposed bar C upwardly into its inoperative position. When it is desired to lower the awning it is only neces sary to pull downwardly on the tape 6 so as to turn the roller B in the opposite direction and unwind the fabric A from the roller, the yoke-shaped extension member and the transversely-disposed bar C moving downwardly automatically into the position shown in Figs. 1 and 2.

The transversely-disposed bar C is pro vided at its ends with sleeves 7 which slide on the guide r'ods 5 and said guide rods are provided with stops that arrest the downward movement of the transversely-disposed barv C, butwhich have no afiect on the vertical movement of the extension member to which the lower end of the fabric A is connected. In the form of my invention herein shown the stopsjust referred to are integrally connected to the guide rods 5 and are preferably formed by squeezing or pressing each of the guide rods 5 at a point intermediate the ends of same so as to change the cross-sectional shape of the rod and thus form a flat portion 8 on same of sufficient width to prevent the sleeve 7 from sliding downwardly past said fiat portion butgnot wide enough to interfere with the vertical movement of the sleeve 4: upwardly or downwardly past said flat portion. As shown in Fig. 4, the sleeve-7 is approximately of the same internal diameter as the diameter of the rod 5. Consequently, the upper end of. the flat portion 8' on said rod will serve as a stop 8 "wthat limits the down ward :inovement of the sleeve 7 connected to one end of the transversely-disposed bar C. The other, sleeve 4:; on said guide rod, to which one of the side arms 3 of the extension member is connected, is made a trifle larger than the diameter of the flat portion 8 011 the guide rod 5,so that, said sleeve will travel freely pastsaid flatportion. In the awning herein shown the transversely disposed bar C is pivotally' connected to the sleeves 7 by means of pins 9 which pass through. elongated slots 10 in the bar C, thereby permitting the bar C to assume a slightly angular position without binding on the guide rods 5 and also permitting sufiicient lateral play between the sleeves 7 and the bar C to compensate for any slight'mal-alinement of the two guide rods 5 on the window frame. The guide rods 5 can be secured to the window frame in.various ways without departing from the spirit of my invention, and if desired, the sleeves 7-to which the transverse bar C is connected can be provided with forwardly-projecting lugs 11 that serve as abutments against which the cross piece 2 of the extension member strikes and moves the bar C upwardly during the operation of raising the awning.

A window awning of the construction above described can be cheaply and installed quickly andeasily, owing to the fact that it is not necessary to semanufactured cure stops to the window frame to arrest the downward movement of the transverselydisposed bar C. Furthermore, by equipping.-

1. A window awning, comprising a strip' of fabric, a roller to which the upper end of saidfabric is connected, vertical guide rods arranged at the sides of the window opening, an extension member connected to the lower end of said strip of fabric and provided with sleeves that slide vertically on said guide rods, a transversely-disposed bar under which the fabric passes provided at its ends with sleeves that slide on saic guide rods, and stops on said guide rods that arrest the downward movement of said transversely-disposed bar but which have no affect on the sliding movement of the sleeves on the extension member.

2. A window awning, comprising a strip of fabric, a roller to which the upper end of said fabric is connected, vertical guide rods arranged at the sides of the window opening, an extensionmember connected to the lower end of said strip of fabric and provided with sleeves that slide vertically on said guiderods, a transversely-disposed bar under which the fabricpasses provided at its ends with sleeves that slide on said guide rods, and integral stops -on said guide rods of such form and dimensions that the sleeves on the extension member can slide freely past same but being large enough to arrest the downward movement of the sleeves on said transversely-disposed bar.

3. A- window awning, comprising a strip of fabric, a roller to which the upper end of said fabric is connected, guide rods arranged at the sides of the window opening, an extension member connected to the lower end portion of said strip of fabric and provided with pivotally connected sleeves that slide vertically on said guide rods, a transversely-disposed bar under which the fabric passes, sleeves on said guide rods joined to said bar by slot and pin. connections, and an integral stop on each of said guide rods formed by squeezing or. pressing said guide rod so as to change the cross-sectional shape of same, said stops being of such dimensions that they arrest the downward movement of the sleeves on the transversely-disposedbar but have no affect on the sliding movement of the sleeves connected vto the extension member.
