SPECIFICATION forniing part of Letters Patent No. 703,693, dated July 1, 1902. hpplication filed \Ianuary 20, 1902. Serial No. 90,489. (No model.)

To all whom, itmcty concern: Be it known that LWESLEY S. BoWsER, a

city of St. Louis, in the State of Missouri,-have invented certain'new and useful Improvements in Means for Operating Awnings, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to means for raising and lowering that class of awnings attached to and adapted to be wound on rollers, the construction of the device'being such that the roller may be quickly and efficiently rotated to wind the awning thereonto or permit the unwinding of the awning. I

The invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a side elevation illustrating my device. Fig. II is a view partly in frontelevation and'partly in vertical section. FigIII is a vertical cross-sectional view taken on line III III, Fig. I.

1 designates the roller of an awning, having a shaft 2, that is supported in suitable hangers at the desired elevation.

3 is a fragment of the awning on. the roller.

1 designates a bevel-gear fixed to the shaft 2 at the end of the roller 1, and located beside on the shaft and held from endwise movement thereon by a collar 6, secured to the shaft by a set-screw 7. i

8 is a vertical shaft having its upper end loosely positioned in the swing-socket'5, so as to be capable of turning freely therein.

9 is a bevel-pinionheld to the vertical shaft 8 by a set-screw lOand'having its teeth arranged in meshing engagement with the teeth 11 designates a box adapted to be mounted on the wall of the building'to which the awn-, ing is applied and through the upper portion of which the vertical sh'aftSpasses, so as to rotate in the box, the shaft being upheld by a supporting-collar 12, containinga set-screw 13. Fixed to the lowerw'end'of the vertical shaft 8, within the box 11, is a bevel-pinion 14, that is held to said shaft by a set-screw 15.

16 is a bevel-pinion that meshes with the v bevel-pinion 14 and is mounted on a shaft 17,

horizontally positioned in the'box 11 and adapted to receive a crank 18, by which it may be turned. On the shaft 17, within the box 11, is a ratchetlf), that is adapted to receive the engagement of a pawl'20,'pivotally connected to the box 11. 1

' In the practical use of the device the shaft 17 is rotated through the medium of the crank 18, and by the intermeshing of the bevel- pinions 14 and 16 rotation is imparted to the vertical shaft 8, and consequently .to the bevelpinion 9, carried thereby. In the rotation of the vertical shaft its upper end turns freely in the swing-socket 5, and through the interineshing connection between the bevel-pinion 9. and thebevel-gear 4 rotation is imparted to the'roller-shaft 2 to wind the awning 3 on the'roller 1 or permit its unwinding therefrom. The swing socket 5 being loosely mounted on the roller-shaft hangs freely suspended. Therefore the roller-shaft may turn fre'elytherein and the coinciding parts operate with freedom and ease of action.

' In many buildings to which awnings are applied, such as those containing store-rooms, there are projections or lintels that protrude beyond the faces of the walls a very considerable distance in some instances and to which it is necessary to attach the roller or a roll-awning, and it is the intention of my invention to providean awning-operating construction that may be so mounted as to set in wall-facings irrespective of'the projection to which'the. awning-roller is applied. It is apparent that in awning-operating means to be universally adjustable upon buildings having more or :lessprojecting wall portions, as stated, it is highly-essential that the construction of the awning-operating means be such that the vertical 'operating shaft may be placed in varying degrees of uprightness or inclination with respect to the building-wall, ,and:this my construction provides for.

will be seen from the drawings and the foregoing description that the swing-socket 5 enables the mounting of the shaft 2 of the awning-roller in any position above i the operating-gearing beneath it, either in 'a vertical plane above it or to one side of'a" vertical plane, inasmuch as the swing-socket may be moved on the roller-shaft to position it so that it will properly receive the upper end of the vertical operating-shaft irrespective of whether the roller-shaft is directly above the lower support of the vertical operating-shaft or at one side of a vertical plane from said support. In this connection it is only necessary to properly mount the lower end of the vertical operating-shaft in its support in a manner that will enable it to stand upright or extend upwardly in an inclined direction.

I claim as my invention- In a device of the class described, the combination of a roller, a shaft on which said roller is mounted, a bevel-gear fixed to said
