AWN IN G-ROLLER AUTOMATIC STOP.

Application filed February This invention has relation to certain new and useful improvements in an awning roller automatic stop and has for its primary object the provision of a structure which is of simple construction and operation as well, and whlch may be I as highly eflicient in use,

employed for practically all awnings.

The invention has for another object the provision of an awning roller automatic stop which may be readily adjusted to cause automatic stopping of the rotation of the roller when the awning is unwound suiiiciently, thus preventing wrapping or winding of the awning canvas in the wrong direction around the roller.

The invention has for its further object the provision of an awning roller automatic stop which is composed of the minimum number of parts of simple construction and arrangement and which will be highly eificient in use. I

With the foregoing and other objects in View, as will appear as the description proceeds, the invention resides in the construction, combination and arrangement of co operating elements as hereinafter more specifically set forth, claimed and shown in'theaccompanying drawings forming a part of the present application and in which:

Figurel is a perspective view of the roller in use. i

Figure 2 is an enlarged perspective View of the roller, removed and with parts broken away.

Figure 3 is a fragmentary sectional view through the roller.

Figure 1 is a View similar to Figure 3,,

showing a' slightly modified form of the invention.

Figure 5 is a transverse section, substantially on the plane of line 55 of F igure 4, looking in the direction indicated by the arrows.

Referring more in detail to the drawing, in which similar reference characters designate corresponding parts throughout the several views, it will be noted that the shaft of the roller is composed of sections 10 and 11, which are supported respectively in bracket bearings 12 and 13. The bracket bearings 12 and 13 have oppositely directed base portions or flanges 1 provided with suitable openings 15 to receive attaching members through the medium of the bracket bearings 12 and 13 may be firmly secured upon a wall or other support, as will be readily under- I the roller core 19 7 tion 21 of the shaft 2, 1926. Serial No. 85,461.

"stood by referring to Figures 1 and It will also be seen from these views that the awning canvas 16 is wound upon the roller outer sleeve 17 in the usual manner or unwound from this sleeve by operation of the control shaft 18, the upper end of which 1 extends intothe bracket bearing 12 and has appropriate driving means with the shaft sectionrlO. The shaft section 10 is rigid with the roller outer sleeve 17 and the roller core 19, on which the sleeve 17 is firmly mounted; v a

The shaft section 11 is adapted to be locked into the bracket bearing 13 after adjustment, as will be later more clearly under- 20 or" other approstood, by a cotter pin priate means, thus preventing rotation of the shaft section 11 during winding and unwinding of the awning canvas 16. The shaft sec tion 11 extends in and through the end of and is provided with a threaded portion 21 extended through the elongated pocket 22 provided in the roller ace of core 19 and; opening upon the inner the roller sleeve 17, the core 19 being practically of rectangular form in cross section throughout the greater portion of its length. The inner end of the shaft section 11 is extended through the transverse partition 23 in the core 19 and into the smaller orauxiliary pocket 24, a roller 25' being then s'ecured upon the same, within the pocket 24 and firmly held on the inner end of the shaft section ll-by a pin 26 or'the like extended through the collarf25 and through the inner end of the shaft'section 11', as clearly shown in F igures-2, 3and 4 of the drawings. stop nut 27works upon the threaded persection 11 within the pocket 22 and travels back and forth on the shaft section 11 from one end to the other of the elongated pocket 22, the walls of the pocket22 preventing turning of the nut 27 within the pocket 22. It will therefore be seen that rotation of the roller in either direction may be regulated by proper adjustment of the shaft section 11 to place the nut 27 a certain distance from one end of the pocket 22 before placing the cotter pin 20 through the bracket bearing 13 and the outer portion of the shaft section 11 as shown in Figure 2.

In the modified form of the invention shown in Figures 4: and 5, the core of the roller is constructed similar to the preferred form with the exception that it has a cap A IL w an awning canvas 29 provided on its outer end with an annular flange 29 carried thereon to receive the reduced end 28 of the halves or longitudinal sections 28 of the sectional or twopart roller sleeve 17 which in this form may be made of wood or other appropriate material.

In both forms of the invention, the sleeve 17 may be secured to the core near the ends of the latter by appropriate bolts 30, as illus trated in Figures 3 and 4, to thus cause rotation of the core 19 with the sleeve 17. It is believed the complete construction and operation of the'invention may now be apparent from the foregoing paragraphs taken in connect-ion with the accompanying without further detailed description. It may be briefly stated, however, that the stop nut 27 may be readily adjusted on the threaded portion of the shaft section 11 or 11 either before or after mounting of the roller in the bracket bearings provided for the end shaft sections 10, 11 or 11 The pin 20 may then be passed through the outer end of the sections 11 or 11' and through the bracket bearing in which such shaft section is mounted, thus holding the shaft section 11 or 11 against rotation in its bracket bearing 13. During winding and unwinding of the awning canvas 16 on the sleeve section 17, the stop nut 27 will work back and. forth on the threaded portion of the shaft section by which it is carried and within the pocket 22 of the core 19, the stop nut 27 finally striking upon one end wall of the pocket to prevent further rotation of the roller sleeve 17 and consequently winding or unwinding of the 16. A slight change of the adjustment of the nut 27 may be made by withdrawing the pin 20 and turning the.

shaft section 11 or 11 with respect to other parts of the roller structure and then replacing the pin 20 to prevent further independent rotation of the shaft section 11 or 11*. This adjustment of the nut 27 will permit increase or decrease in the winding or unwinding of the awning canvas 16 as the roller sleeve 17 drawings tails of construction,

and core 19 are operated in the usualmanner, It is also apparent that a roller constructed in accordance with this invention will eliminate danger of the awning canvas 16 being only partly unwound or being wound upon the roller sleeve 17 owing to continued rotation of the roller in the same direction after complete unwinding of the awning canvas 16. Furthermore, when the present form of roller is employed,

in the wrong direction danger of the canvas awning 16 sa gingb when unwound, is overcome.

While the preferred embodiments of the invention have been disclosed, 't; is to be understood that minor changes in the'derangement-of cooperating elements, may be resorted to withinthe scope of what 1S combination and ar claimed without departing from the spirit of the invention.

hat is claimed is v A device of the character described in. cluding a roller sleeve, a shaftrsection rigid with one end of said sleeve, a removable core fitted in the opposite end of said sleeve and secured thereto, said core having spaced pockets formed therein, a second shaft sec.- tion loosely journaled in said core and extending longitudinally through said pockets and threaded for a portion of its length, bracket bearings supporting the outer ends of said shaft sections, said second shaft section being normally secured in said bearing against movement, means for rotating said roller sleeve and a nut working on the threaded portion of said second shaft, being disposed in one pocket contact with the side walls thereof, whereby the rotation of the roller will cause the nut to travel on said shaft, said nut limiting the' rotation of the roller upon contact with the end walls of said pocket, said second shaft being releasable from its bracket bearing to permit adjustment of said nut on said shaft.

In testimony whereof I afiix my signature.
