WNING-FIXTURE,

To all whom it may concern:

Be it known that 1, CHARLES TALLEY, a citizen of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Awning-Fixtures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. V V V This invention is an improvement on roller awning fixtures, and-relates more particularly to theraising and lowering of the awning. I

The primary object of this invention is to provide a compact, cheap, safe and better awning fixture, combining simplicity of operation with the minimum amount of applied force.

With this principal object in view my invention consists of a compact application of the law of leverage which is particularly adapted for use in the raising and lowering of awnings with the minimum amount of effort to the operator, and with the simplest possible fixture therefor.

The invention will'be more fully understood after reference to the accompanying drawings, in which like parts are indicated by similar reference symbols throughout the several views, and in which Figure 1 is'a side view, with parts shown in section, of an improved awning fixture constructed in accordance with the present invention, andshown as applied to a portion of an awning and a building.

Fig. 2 is a front view of the same off center.

Fig. 3 is an enlarged side View of the improved fixture.

Fig. 4 is an interior view of the casting.

Fig. 5 is a vertical sectional view through the wheel. y

V Fig. 6 is a front elevation thereof.

Fig. 7 is a cross sectional view. showing an expanding device for-connecting the fixture to the awning shaft.

Fig. 8 is a view in elevation of the cross bar carrying the pinions, Y

Specification of Letters Patent.

Patented Aug. 2, 1921 Application filed December 9, 1920. Serial No. 429,461.

. Referring more particularly to the drawngs designates generally an awning proectlng out from a building wall indicated at 2, and wound about the usual shaft or pole 3. The supporting arm or strut is indlcated at 4:, and carries a roller 5, movable up and down, in contact with a rod 6 held in

brackets

7 and 8, secured to the building wall. A coupling piece 9 is threaded or otherwise formed on one end to receive the adqacent end of the arm or strut 4, and is bifurcated on its opposite end and perforated to receive the pin 10 on which the roller 5 rotates. Y

The roller 5 is preferably grooved to fit the curvature of the rod 6. A guide piece 11 is also associated with the roller 5 and rod 6 and is substantially U-shaped, being also adapted to engage with the pin 10 of the roller 5 by which it it held in place. The guide plece 11 extends beyond the peripheral edge of the roller and lies about the bar 6, so as to prevent the roller jumping the rod and to direct it in its movement up and down on the same.

The interior construction of the gear box fixture is more particularly disclosed in Figs. 3 to 8 inclusive, in which 12 designates a casting having a wall bracket 13 projecting from one side thereof to receive screws or other fastenings by which the fixture is secured to the building front 2 of Fig. 1. Spider arms-indicated at 14 in any suitable number are made to project across one end of the casting 12, or casting end'can be closed in order to support a bearing 15. A shaft 16 is received in the bearing 15 and has made in one piece therewith a bar 17 provided with

pins

18 and 19 for carrying

pinions

20 and 21, respectively. The pinions are adapted to mesh with an internal gear 22 formed within the casting 12. The upper portion of the casting is provided with an overhanging flange 23 at one side thereof, said flange being provided with

slots

24 and 25 at diametrically opposite points and substantially in horizontal alinement- I A projecting piece 26 arranged at the upper portion of the flange 23 is provided with an opening 27 to receive a pin 28 rojecting from a closure plate 29 whic is also preferably of an openwork construction, having a spider 30 providing a central bearin also receiving the shaft 16.

" -ugs 31 extend from the edge of the cover A headed bolt 35 passes through the open; 7 ings in the ear 34 and lug 32, and has a square portion adapted to engage the openin 33 and isfastenedby a nut. On the b0 t 35 is swingingly mounted a pawl 36 having a tooth 37 adapted to engage ribs 38 in a wheel 39, adapted to receive an endless operating rope or chain 40. The pawl 36 carries a weighted arm 41 for tending to urge it into engagement with the ribs 38 in order to arrest the progress of thegrooved wheel '39. The groove in the wheel 39 is V-shaped and of sufficient size and depth to frictionally receive the rope or chain. The ribs 38 are disposed alternately in order to grip the rope or chain as indicated; in Fig. 11.

An eye 42 projects beyond the tooth 37 of the pawl and isarranged to receive the oper ating cable or chain'40 therethrough in order that an outward or downward pull upon the cable may initially displace the tooth 37 from-the rib 38. of the wheel, thus allowing the wheel to be revolved.

The wheel 39 carries a pinion 43 receivable between the

pinions

20 and 21, and by which movement is imparted to the awning pole as later described.

The awning pole 3 is indicated in Fig. 7 as being hollow, at least at one end, in order to receive the expansible hollow core 44 of an operating gudgeon or trunnion 45. A metal plug 46 internally threaded lies within the expansible portion 44 of the gudgeon and is adapted to be drawn inwardly by the action of a bolt 47. 1

The shaft 16 is provided with keyways 49 in order to receive the keys 50 on a reduced portion of the gudgeon 45. A wedge 51 is made on the hilt of the gudgeon to frictionally and tightly bind against the end of the varying sizes of rollers 3. A small pin-52, shown in Figs. 1, 2 and 3 projecting from the casting, is for the purpose of fastening the side of the awning which does not roll up.

Small projections 53 on the lug 32 act as stops to regulate the action of the locking device 36. I

In operation the endless rope or chain 40 is pulled downwardly in the desired direction accordingly as the awning is to be raised or lowered. This cord passing through the eye 42 will act to first swing the pawl 36 downwardly in'opposition'to the action of the arm 41. Further movement of the operating cable will revolve the wheel 39 and with" it its pinion 43. The

pinion 43, meshing with the two

pinions

20 and 21, will tend to turn the same so that they will step: around within the internal gear 22, thus developing in a manner which will be well understood a relatively torque or turning power upon the shaft or pole of the, awning. This turning power or torque in the awning pole will result from a small application" of force upon the operating cable.

It will be obvious that various modifications might be made in the herein described apparatus, and in the construction, combination and arrangement of parts which could be used without departing from the spirit of my invention.

' Having thus described nay-invention what Ilclai'm and desireto'secure' by Letters PatentoftheUnitedjStates is a e l.
