FRANK BAILEY, OF MUSKEGON, MICHIGAN.
AWN ING-FIXT URE To all whom it may concern:
Be it known that I, FRANK BAILEY, a citizen of the United States, resident of Muskegon, in the county of Muskegon and State of Michigan, have made a certain new and useful Invention in Awning-Fixtures; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part of this specification.
The invention has relation to roller awning fixtures, and it consists in the novel construction and combinations of parts as hereinafter set forth.
In the accompanying drawings, illustrating the invention, Figure 1 is a front View of the awning roller, its supports and actuating means; Fig. 2 is a side view on a larger scale of the awning roller, its main su porting casting and its actuating means; Fig. 3 is a detail perspective view of the main supporting casting and the actuating means for the awning roller; Fig. 4 is a detail perspective view of the main supporting casting for the awning roller; Fig. 5 is a section on the line 5-5 Fig. 2; Fig. 6 is a detail perspective view of the sprocket wheel; Fig. 7 shows by detail perspective views the means for centrally supporting the awning roller; Fig. 8 shows by detail perspective views the two members of the bracket for supporting the lower chain roller; Fig. 9 is a detail side view of the lower chain roller and its supporting bracket; Fig. 10 is a detail side view of the bearing piece.
In these drawings the letter a, designates the awning and b, the roller or pole on which it is wound.
In order to actuate the awning roller the following mechanism is provided. 0, is a supporting casting having a wall late 0', adapted to be secured to the wall of the building, and a right-angle extension (Z, provided with a horizontal top flange d, at right angles thereto, extending at each side thereof and having a semi-cylindrical recessed portion e. This right angle extension has a horizontal notch f, opening thereunto from its outer end.
In the semi-cylindrical recessed portion or bearin e, of the top flange of the casting is locate a short hollow shaft 9, carrying at Specification of Letters Patent.

its inner end portion the cup-form casting g, which embraces and has fixed connection with the end of the roller 5, for rotation of the same, the outer end of the shaft 9, carrying fast thereto the spur gear wheel gflwhich in the present case acts as a worm gear wheel. Fitting closely in the horizontal notch is a bearin piece It, having an interme iate collar h and at its outer end a perforated circular enlargement or eye portion 1%. Fitting in the eye h*, at its outer end and at its inner end in a bearing 0 of the wall plate is a short worm shaft 2', having a worm i, which engages the worm wheel g, and carries fast thereto at its inner end a chain or sprocket wheel j, having detachable spline connection therewith.
In assembling the parts the reduced inner end portion of the worm shaft 2', is first en gaged at its inner end in the bearing 0 of the wall plate, the chain wheel being previously slipped thereon, when the bearing piece la, is slipned within the notch f, of the wall plate extension until its eye portion 11?, engages with the reduced outer end portion of the worm shaft, when the collar h, of the bearing piece having close engagement with the flange extension (2, of the wall plate, in connection with the close fit of the inner end of the bearing piece in the notch, will prevent any sag or drop of the bearing piece and of the worm shaft supported at its outer end thereby. The short roller shaft 9, carrying the cup-form casting g, is then placed in its bearing 6, and the worm Wheel, which may be shrunk thereon or have spline connection therewith, is sli med in position engaging the worm. A top piece (2, secures the shaft 9, in position in its hearing. The roller 7), of the awning is then secured at one end in the cup-form casting aforesaid.
The chain wheel j, is a deep grooved sprocket Wheel with sprocket teeth in center of groove. A regular sprocket chain 771., may be used for operation of the chain wheel.
For awnings of ordinary length no lower chain or sprocket wheel is needed, the awning being easily rolled up by simply pulling upon the endless chain, the worm gear furnishing the necessary power and the awning bein at the same time prevented from roll ing down or unrolling by such worm gear. In unrolling the awning for use the chain is pulled in the opposite direction, the weight of the roller or pole and of the awning assisting. For awnings of unusual length,
however, a lower chain wheel 0, may be provided, secured in stationary bearings 0, and the shaft of which is provided With an oper ating crank p. The bearings 0', consist preferably of an inner plate q, having a hook lug a, at its bottom and a lug 7-, at its top, an outer detachable plate of bowed character having a bottom notch 9 designed to en gage the hook lug q", and an opening 7", at the top for engagement with. the lug a", which has a key 1' engaging a perforation thereof.
In order to support centrally the awning roller and awning rolled therearound and at the same time cause the awning to roll tightly and smoothly around its roller, a wall plate 8, is provided having right angle extensions .9, s, carrying lower rollers 25, t, located below the awning roller or pole, and upon which the pole rests when the awning is rolled therearound. An upper wall plate a, has right angle extension if, having branches t t carrying an upper roller a, which lies above the awning pole or roller and acts to cause the awnin to roll tightly therearound, at the same time keeping the awning at all times closely rolled.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In roller awning fixtures, a wall plate having a right angle supporting extension provided with a notch at its outer end and a horizontal top flange having a semicylindrical bearin seat therein, a bearing piece removably tting in said notch and having an intermediate collar lying closely against said right angle extension and having bracing engagement therewith, said bearing piece having an eye at its outer end, a worm shaft having bearings at its inner end in said wall plate and at its outer end in said eye of the bearing piece, said worm shaft having a Worm and a chain wheel fast thereon, a short shaft fitting in the bearing of the horizontal top flange and adapted for engagement with the awning roller, and having a worm wheel engaging said worm.
2. In roller awning fixtures, a wall plate having a right angle flange provided with an upper horizontal bearing and a lower horizontal notch at right angles to said bearing, a bearing piece in said notch having an intermediate collar having bracing engagement w;ith said flange and an eye at one end, a worm shaft having bearings at one end in said wall plate and at its other end in said eye, said worm shaft carrying a worm and a chain wheel fast thereto, and a shaft fitting in said upper horizontal bearing, adapted,
for engagement with the awning roller and having a worm wheel engaging said worm.
3. In roller awning fixtures, a Wall plate having a right an le flange provided with an upper horizontal Ivearing and a lower horizontal notch at right angles to said bearing, a bearing piece in said notch having an intermediate collar having bracing engagement with said flange and an eye at one end, a worm shaft having bearings at one end in said wall plate and at its other end in said eye, said worm shaft carrying a worm and a chain wheel fast thereto, and a shaft fitting in said upper horizontal bearing adapted for engagement with the awning roller and having a worm wheel engaging said worm, a wall plate having a lower hook lag and an upper lug, an outer bowed plate having a lower notch engaging said hooked lug and an upper opening engaging said upper lug, and a lower chain wheel having a shaft provided with bearings in said wall plate and bowed plate, and an operating crank.
In testimony whereof I afiix my signature, in presence of two witnesses.
