SPECIFICATION forming part of Letters Patent No. 342,568, dated May 25, 1886.

I Application filed March 1, 1886.

To all whom it may concern:

Be it known that I, CHARLES BERNHARDT, a citizen of the United States, and a resident of Chicago, in the county of Cock and State of Illinois, have invented certain new and useful Improvements in lVIachine-Awnings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in that class of awnings in which the cloth or canvas is rolled up on a horizontal drum or roller when not required for use through mechanism :5 extending to a position convenient to the operator; and the objects of the present improvements are, first, to provide means easy and convenient of operation for drawing the side wings or flies up against the under side of the awning-canvas, so that they can be readily rolled up wit-l1 the same; second, to furnish means whereby the spread or extension of the awning to cover a more extended area is effected automatically by the operation of let- 2 ting down or unfolding the awning; third, to

provide means to obviate the tendency to buckling of the awning-canvas at its center, when the side wings or flies are rolled up along with it on the winding drum or roller; fourth, to 0 afford means to cause the awning-canvas to cut and roll upon its windingdrnm in an even and compact manner; and, fifth, to pro-. vide an improved loop or eye for the passage and attachment of the operating-cords em- 3 5 ployed in the present improvements. I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which-- Figure 1 is a sectional elevation illustrating 0 my invention applied to the front of a building; Fig. 2, an under perspective view of the awning detached, illustrating the means employed to manipulate the side wings or flies; Fig. 3,an enlarged detail section of the winding 5 drum or roll of the awning, and Fig. 4 a detail view of the attaching or guide eye for the operating-cords of the awning.

Similar letters of reference indicate like parts in the several views. Referring to the drawings, A represents the main canvas portion of the awning arranged to wind upon the drum or roller B, journaled Serial No. 193,673. (No model.)

in suitable bearings attached to the building front, and provided with achain-wheel,0,over which passes the operating endless chain D, which at its lower end passes over a similar chain-wheel, supportedin a casing, E, within easy reach of the operator,and provided with suitable means for the attachment of the operating hand-crank e, and also a pawl or dog be (not shown) for holding the parts at the required adjustment. The lower chain-wheel with its casing E is arranged with its axis at right angles to the axis of the upper chainwheel Oand winding-roll B, so that it can be arranged compactly against the building front and offer but very little obstruction at such point. Such arrangement also permits of the use of a much longeroperatingcrank, 6, than could be employed were the axis of said chainwheel arranged parallel with the building front.

The awning-canvas A is attached at its lower and front edge to the front rodor bar,F, of the aw ning-frame, having arms G, by which it is pivoted to the building front in manner as follows, to attain an enlarged extension of the awning out over the pavement: The inner ends of the arms G are pivoted to the sliding blocks that are arranged to move upon .80 the verticallyarranged slide-bars H, permanently attached to thefront of the building,as shown,the arrangement being such that when the awning is rolled up said blocks will be at their lowest position upon the slides H, asin- 8 dicated in dotted lines in Fi 1,and when the awning is lowered for use said blocks will be at their highest position, as indicated in full lines in Fig. 1, with the arms G horizontal, such raising of the blocks being accomplished 3 automatically by a chain or rope, I, one end of which is attached to said blocl ,and passing over a pulley, 2', attached to the building, the other end being attached by an eye or other suitable means to the arms G,at a suitable dis- 5 tance from its pivotpoint. By this construction the weight of the awning in its descent will automatically liftthe inner ends of the arms G in a vertical direction toward a horizontal plane,and effect the required extensign m0 of the awning over the pavement. The side wings or flies, J ,will be of the usual triangular form,permanently secured to the main awningcanvas A. To their extreme lower and inner secured in that position by engaging the ring to j upon a hook,-j, attached to the-front rod,

F,near its end. When the awning is down and in use, the side wings or flies will be tied to the building in the usual manner to prevent flapping.

A is a central thickening or re-enforce strip secured to the under side of the main awning at its center. so as to fill up the same to a thickness equal,or nearly so,to that possessed by its outer portions when the wings or flies are drawn up against the same, the purpose being to prevent the buckling of the canvas as it is being rolled up due to the uneven thickness'of its diflerent portions.

The winding drum or roll B for the awningcanvas is made in the form of a polygon, preferably a hexagon or octagon, as I find such a shape, due to its projecting edges, causes the canvas to cut and roll very compactly into a small compass.

The eyesj'j for the passage and attachment of the draw-cord j are made of a triangular form, so as to admit of a firm and substantial attachment to the awning-canvas,and at the same time hold and guide the drawcord in its proper position.

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

1. The combination, with an awning the pivot-arms of which are adapted to move vertically at their inner ends,of a chain or cord connecting said inner ends with a moving portion of the awning, so that the movement of the awning in unfolding will automatically draw the inner ends of the pivot-arms up into a horizontal position to effect an outward extension of the awning-canvas, substantially as set forth.

2. The combination of the awning pivot-arm G, pivoted to a block, and slide H,with the chain or cord Larranged to pass over the pulley i and connected to a moving part of the awning,essentiall y as and for the purpose set forth.

3. The combination, with a roll-up awning and mechanism,essentiallyas herein described, for operating, of the awning-roll B, made polygonal in cross-section, for the purpose set forth.

4. The combination ofthe main awning-canvas A. side wings, J,w1'th the draw-cord j, arranged to pass through eyes j 'j and central eye, j ,with its pendent loop provided with a ring, j the parts being arranged to admit of the ringj being engaged on a hook,j, when the side wings are drawn up against the under side of the main awning, as herein described, and for the purpose set forth.

5. In an awning ofthe type herein described, the awning-canvas A, provided with a central reenforce strip, A, and side wings, J J, as described, and for the purpose set forth.

6. The combiuation,with an awning,as herein described, and the means for operating its side wings, of an eye, j, of a triangular form, as described, and for the purpose set forth.

Signed at Chicago, Cook county, Illinois, this 11th day of January, 1886. v

' CHARLES BERNHARDT.

In presence of ROBERT BURNS, M. J. KENNY.
