AWNING.

SPECIFICATION forming part of Letters Patent No. 743,711, dated November 10, 1903.

Application filed March 81, 1903. Serial No. 150,415. (No model.)

as will en able others skilled in the art to Wh ich it appertains to make and use the same.

My invention relates to certain improvements in awnings, but more particularly to that class of such devices which are known as rolling awnings, and has for its object to provide a construction which is exceedingly simple, readily manipulated, and not likely to get out of order; and with'these ends in view my invention consists in certain details of construction and combination of parts, such as will be hereinafter fully set forth and then specifically designated by the claims.

In the accompanying drawings, which form a part of thisapplication, Figure 1 is an elevation showing the position of the parts of my improvement when they are assembled and ready for use; Fig. 2, a section at the line aas of Fig. 1; Fig. 8, a detail elevation of the gear-bracket; Fig. 4, a detail sectional elevation of the lower box which contains the pri-" mary gearing; and Fig. 5, a sectional elevation showing the manner in which my improvement is utilized in connection with ordinary brace-rods, the parts in solid lines being in the position which they assume when the awning is up, while the dotted lines show the position of the brace rod and awning when the latter is down. I

Similar numbers of reference denote like parts in the several figures of the drawings.

1 2 are the brackets which support the roller-bar 3,said brackets being secured in anyordinary manner to any suitable framework of a building. r

The roller-bar 3 at one end is tapped within a cheek-piece 4, which latter is provided with atrunnion 5, which is supported within a bearing 6 on the bracket 1, while the other extremity of said bar is tapped within a bevelgear 7, provided with an outer hub S, which is journaled within abearing 9, that projects from a plate 10, which latter is secured to the bracket 2 by means of a bolt 11.

extends from the bracket 2, the extreme up-' per end of said rod having secured thereto a bevel-gear 16, which meshes with the gear 7.

17 is any suitable cover which incloses the gears 7 16 and the bearings 9 15.

19 is a box secured in any suitable manner to the framework of the building within conveuient reach of an operator, and2O is a short shaft journaled within said box and carrying a bevel-gear 21, (shown in dotted lines,) which meshes with a bevel-gear 22, (shown in dotted lines,) secured to the lower extremity of the rod 14, said rod near its lower end passing through any suitable journal (not shown) in the box. This shaft projects outside the box and is provided with a-suitable wrench-hold 23 and also carries a ratchet-Wheel 24, which is engaged by a pawl 25, pivoted to the box.

From the foregoing description it will be readily understood that when a crank has been attached to the wrench-hold 23 the turning of said crank will effect the revolution of the roller-bar 3, to which latter is secured the inner edge of the awning, so that the rev-' olution of the crank in one direction will cause the awning to be rolled up on said bar, while the turning of the crank in the reverse direction will effect the lowering of the awnmg.

The ratchet 2a and pawl 25 are not absolutely necessary, since they merely cooperate to prevent any accidental lowering of the awning, although the possibility of such loweringis exceedingly remote.

26 is a bracket secured to the building in adjusted up and down and secured by means for the purpose presently to be explained.

If the bar 3 is quite long, so as to carry a wide awning, it becomes necessary to afford this bar some support when the awning is rolled thereon, because at that time said bar must sustain considerable weight, and therefore I have provided this bracket 26, and the weight of the rod and awning will be supported directly upon the rollers 28 29, while from the plate 81 extends an arm 3%, which is curved, so that its extremity depends in close proximity to the outer roll 28, and to the end of this arm 3% is secured a roller It will thus be seen that these arms will practically encircle the awning when it is rolled upon the bar 3, and therefore it will be clear that any outward thrust of this bar during the manipulation of the awning will be resisted by the rollers at the ends of these arms.

The arm may be adjusted up or down according to the size of the awning-roll contained upon the bar 3, and if said bar is quite long several of these brackets may of course be employed.

36 represents one of the brace-rods, whose lower end is hinged to any suitable bracket 37, secured to the side of the building, and whose upper extremity is secured to the awning 38 near its outer edge, as shown at Fig. 5. Several of these brace-rods are of course employed and are connected with the awning at certain intervals throughout its width, and when any ordinary-crank is applied to the wrench-hold 23 and is turned in the proper direction the awning will be unrolled and the brace-rods will drop until they assume the horizontal position shown in dotted lines at Fig. 5, the position of the awning being shown by the dotted line 35).

The plates and 12 are made separate from the bracket 2, so that it will not be neceesary to take down the bracket whenever the roller-bar 3 is to be removed or replaced. The plate 12 is secured to the bracket 2 by means of the two screws 13, and this plate is ordinarily never disturbed. The plate 10 abuts against the edge of the plate 12 and is secured to the bracket 2 by means of a single bolt 11, and as this plate 10 carries the bearing 9 for the roller-bar it will be clear that in order to remove the roller-bar it is merely necessary to withdraw this single bolt 1.1, so

as to permit of the withdrawal of this plate 10 itself.

Should the bearing 9 become worn or broken, it is merely necessary to substitute a new plate 10 without disturbing the bracket 2 in the least.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the bracket 1 having the bearing 6, the bracket 2, the plate 10 provided with bearing 9 and secured by a single gear bolt to the plate 2, the keeper-plate 12 abutting against the plate 10 and secured to the bracket 2, the roller-bar 3 journaled within said bearings and carrying near one end and in proximity to the bearing 9 the bevel-gear 7, the vertical rod 14 whose upper extremity is guided within a suitable bearing on the bracket 2 and is provided with a bevel-gear 16 which meshes with the gear 7, the box 19 within which the lower extremity of the rod it extends, the bevel-gear 22 carried by the lower end of said rod 14, the short shaft 20 journaled within said box and provided with a wrench-hold and carrying a ratchet-wheel, the pawl pivoted to said box and adapted to engage said ratchet-whee the bevelgear mounted on said short shaft within said box and meshing with the gear 22, the awning whose inner edge is secured to the bearing 3, and the brace-rods whose lower ends are hinged vto a stationary element while their upper ends are fastened to the outer edge of the awning, substantially as set forth.

2. The combination of the bracket 1 having the bearing 6, the bracket 2, the plate 10 provided with bearing 9 and secured by a single bolt to the plate 2,the keeper-plate 12 abutting against the plate 10 and secured to the bracket 2, the roller-bar 3 journaled within said bearings and carrying near one end and in proximity to the bearing 9 the bevel-gear 7, the vertical rod l t whose upper extremity is guided within a suitable bearin g on the bracket 2 and is provided with a bevel-gear 16 which meshes with the gear 7, the box 19 within which the lower extremity of the rodlat extends, the bevel-gear 22 carried by the lower end of said rod 14, the short shaft 20 journaled within said box and provided with awrench-hold and carrying a ratchet-wheel, the pawl pivoted to said box and adapted to engage with said ratchetwheel, the bevelgear mounted on said short shaft within said box and meshing with the 22, the awning whose inner edge is secured to the bearing 3, the bracket 26 in the rear of the bar 3 and provided at its upper portion with vertical ways 30 and having arms 27 projecting outwardly from its lower portion, the rollers 28, 29, journaled between said arms, the plate 31 having therein an elongated vertieal slot and guided between the ways 30 and provided with an outwardly and downwardly extending arm 34:, the roller 35 secured to the end of said arm, the set-screw extending through said slot into the bracket 26, and the brace-rods whose lower ends are hinged to a stationary element and to whose upper ends the outer edge of the awning is secured, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
