AWNING-ROLLER CENTER SUPPORT.

Application filed November 26, 1923.

This invention relates to awning roller center supports, and, has for its object to provide a device ofthat character which is a distinct and practical improvement to over come certain practical objections to, and de fects in, the universal types of awning center supports by providing an adjustable upper roller supporting arm to prevent the awning roller from accidentally jumping out of the center support during revolving movements thereof, especially when awning gets away from operator, thereby eliminating possible chances of personal injury and property damage.

lVit-h the above and other objects in View, which will be apparent from the foregoing description, the invention consists in the.

novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein.

like characters of reference denote similar parts throughout the several views:

Fig. 1, is a side elevation of an awning roller center support embodying the features of my invention.

Fig. 2, is a front elevation thereof.

Fig. 3, is a vertical sectional view of the device.

Fig. 4-, is a top plan View thereof.

Fig. 5, is an enlarged sectional View, taken on line 55 of Fig. 1.

Referring to the drawings, the reference character 1 represents a supporting member or carrier provided at its side edges with the opposed pairs of upwardly directed arms 2, 8 and 4, whichare suitably spaced apart, as shown in Fig. 1. A. suitable arm 5 is directed upwardly from the rear end of the member or carrier 1 and is provided with an opening 6. A plurality of suitable wooden rollers 7, 8 and 9 are revolubly carried bythe member 1 through the medium of suitable bolts or pins 10, 11 and 12 respec tively, which bolts or pins pass through tubular sleeves 13 carried by the rollers and the ends of which bolts or pins are receivable in openings 14 of the arms 2, 3 and 4. By this H arrangement, it will be apparent that the rollers 7, 8 and 9 span the support or carrier 1 and that they support the roller 15 and the awning 16 rolled thereupon, as clearly shown in Fig. 1.

Carried by the arm 5 of the support or Serial No. 676,959.

carrier 1 is a separable arm which coinprises two preferably curved arms 17 and 18. Curved arm17 is provided at its rear end with a downwardly directed extension or arm 19 which isprovided with an open end slot 20, thus providing a bifurcated extension for the arm 18. A suitable .bolt 21 is employed which passes through the opening .6 of arm 5 and through the slot 20 of arm 19 and is provided with a securing nut for; locking, the two arms 5 and 19. in locked engagement. The bifurcated extension or arm 19 engages the rear face of the carrier arm 5, as shown in .Figs.-1 and 3. The upper face of the curved arm 17 isprovided at its sidev edges with the upwardly directed flanges 22 to provide a channeled seat 23 and this 1 arm is further provided near its forward end with a suitable slotted opening 24:.

The second member 18 of the separable and adjustablev upper arm is mounted upon the channeled seat. 28 of arm 17 and is providedlwith a slotted opening 25... A suitrected ears 28. These ears 28 support a.

guide roller .29 therebetween through. the medium of a suitable bolt or pin 30. engageable in atubular sleeve 31 carried by the roller 29 and the end of the bolt-or pin 39 is engageable in the openings 32 of the cars 28 of arm 18. The guideroller 29 is disposed above and adjacent the supporting roller 9.

It is apparent from the foregoing description andreference to Figs. 1 and 3 ofthe drawings, that the arm 18 mounted upon arm 17 may. be adjusted longitudinally, so as to bring the roller 29 toward or, away from roller 9 so that .any predetermined gap, space or opening maybe provided between rollers 9 and 29, this gap being determined by the size or diameter of thev awning roller 15, the gap being preferably less in distance than the diameter of the awning roller 15, thus preventing any possible chance of the roller jumping off ofthe rollers 7,8 and 9 and out of the support or carrier,causing personal injury and property damage, especially when unrolling the awnings. The flanges 22 of the arm 17 prevent any possible chance of the arm 18 being laterally displaced even though the nut 27 of the bolt 26 should be loosened.

It is of course apparent that the center support is suitably attached to the wall of the building to the rear of the awning roller.

By providing the metallic tubular sleeves for several wooden rollers, it is evident that the rollers will always revolve upon their bolts or pins, thus preventing the wearing out of the awning material by sliding friction which wearin out is usuall due to the rollers sticking and refusing to revolve when winding up the awning or unrolling the same thereby causing the fabric awning material to slide over the rollers instead of being in free rolling contact therewith.

It is evident that the center support or carrier may be of any desired size, but it will be understood that one size carrier or support is capable of supporting an awning roller of different diameters owing to the fact that the guide roller 29 may be moved to or from the roller 9 by adjusting the arm 18 longitudinally upon the arm 17. The arm 18 may be entirely removed and separated from arm 17 when desired.

From the foregoing description, it is evident that I provide a center support for awning rollers, which is strong, durable and highly efficient for the purpose intended in that the roller 29 may be adjusted to the desired distance from roller 9 to prevent the awning roller from leaving the rollers 7, 8 and 9 and jumping off of the carrier rollers, especially when unrolling the awning during which operation it sometimes gets away from the operator and beyond his control and results in personal injury or property damage by falling to the ground.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not wish to be understood as having limited myself to the exact details of construction shown and described, but desire to have it understood that the invention I have shown in the drawings is merely illustrative, as it is manifest that various minor changes may be made in the exact form, shape and particular arrangement of parts without departing from the spirit of my invention, hence I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.

What I claim is:

1. In an awning roller support, a frame composed of a lower frame member having a rigid forwardly extending arm, a set of three supporting rollers carried by said arm with the center roller disposed at a lower elevation than the other two rollers, an upper frame member having a rigid forwardly extending arm, means for securing said lower and upper frame members in different adjusted positions, an extensible arm mounted for sliding adjustment upon the extending arm of the upper frame member, means for rigidly securing the extensible arm in different adjusted positions and a retaining roller carried at the forward end of the extensible arm.

2. In an awning roller support, a frame composed of a lower frame member having a rigid forwardly extending arm, a set of three supporting rollers carried by said arm with the center roller disposed at a lower elevation than the other two rollers, an upper frame member composed of two members, one of which is slidably adjustable with relation to the other, means for rigidly securing the adjustable member in differentadjusted positions upon the other member and a retaining roller carried at the forward end of the slidably adjustable member.

3. In an awning roller support, a frame composed of lower and upper relatively adjustable members and means for securing them in different adjusted positions, an extensible member associated with the upper member in slidablc relation therewith, means for securing the extensible member in different rigid adjusted positions upon the upper frame member, said means comprising a slot and bolt connection, a retaining roller carried at the forward end of the extensible member, and a set of three supporting rollers carried by the lower frame member, the center roller being disposed directly below the awning roller with its axis disposed below the axis of the other two rollers.

4. In an awning roller support, a frame member composed of a lower frame member bearing carried at the ends of said frame member, rollers journaled in said bearings, an upper frame member, means for securing the upper and lower frame members in difierent adjusted positions, the upper member having a channel in its upper face and provided with a longitudinal slotted opening, an extensible arm mounted in the channel of the upper frame member and having a slotted opening to register with the slotted opening in the upper frame member, fastening means passing through said slotted openings for rigidly securing the extensible arm in different adjusted positions upon the upper frame member and an awning engag= ing roller carried at the forward end of said extensible arm.

In testimony whereof, I have hereunto signed my name to the specification.

JOHN DERUS.
