SPECIFICATION forming part of Letters Patent'No. 634,478, dated October 10, 1899.

ApplicationfiledAprilSO,1898. SerialNo. 679,311. (lloincdeh) v To ctZZ whom, it may concern;

Be it known that I', MioHAEL 0. RYAN, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Awnings, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention has special reference to the species of awning in which the awning-cloth is gathered in folds by means of ropes con-.

nected at one end to the free end of the awn; ing and at the opposite end to spools secured to a revoluble shaft extending lengthwise of the awning immediately under the top portion thereof.

The object of the invention is to reduce to a minimum the length, friction, and wear of the hoisting-ropes and to dispense with the use of sheaves or pulleys hung loosely on the building or pivoted to separate supports, which sheaves or pulleys are liable to become detached or otherwise disabled, and thus ruin the efficiency of the entire system; and the object of the invention is, furthermore, to prevent entanglement of the awning-cloth with the aforesaid shaft in the operation ofraising and gathering in folds the said cloth, and to that end the invention consists in the improved construction and combination of parts hereinafter described, and set forth in the claim.

' In the annexed drawings,.Figure l isa front view ofan awning-frame equipped with my invention, the awning-cloth being omitted to better illustrate the invention. Fig. 2 is a vertical transverse section on line \V W in Fig. 1 with the awning-cloth attached. Figs.

3, 4, and 5 are enlarged transverse sectional views respectively on lines X X, Y Y, and Z Z in Fig. 1; and Fig. 6 illustrates a modification of the means for facilitating the operation of raising the awning. I

Similar letters of reference indicate corresponding parts. i p

A represents ,the awning-cloth or awning proper, which is suspended in theusual manner from hooks or other suitable devices fastened to the building, as shown at Ct. To the lower or free portion of the awning is fastened the usual frame b, which holds the awning taut transversely and ispiv'ot-ed to brack ets d d, attached to thebuilding to sustain the awning laterally, as more clearly shown in Fig. 2 of the drawings. Beneath the fastenin'g devices a a' of the upper end of the awning-cloth is a revoluble shaft e, extending across the exterior of the building and jour naled in suitablebearings e, firmly secured to the building. To the shaft are adjustably fastened suitable drn'ms or spools f f, upon each of which is wound a ropec, which extends from thence directly to the frame I), and thus dispenses with loose sheaves or pulleys and reduces to a minimum the length, friction, and wear of the ropes.

Various means may be employed for turniug the shafte to cause the wiresor ropes cc to be wound and unwound on the spools ff, and thereby raise and lower the awning. I prefer to employ for that purpose a chainwheel h,fastened to the shaft e, and a chain 72', suspended therefrom to be operated byhand and, to be permitted free movement when released from the hand.

To facilitate the operation of turning the shaft e, I employ a suitable counterpoise, which may consist eitherof a spiral spring i, as shown in Figs. 1 and 3, or of a weight j, as represented in Fig. 6 of the drawings. The spring '2' surrounds the shaft and is suitably fastened at one end to the building and connected at the opposite end to a collar Z, which is adjustably mounted on the shaft to permit the tension of the spring to be increased or diminished as may be desired, to facilitate the aforesaid operation. IV hen the weight j is preferred, I attach said weight to the free end ofa chain or ropej, attached to a drum t, secured to the shaft 6.

To look the awning in its raised position, I employ a suitable detent adapted to engage and release the shaft. I preferably form said detent of a wheel D, fastened to the shaft 6 and provided with notches an in its periphery, and a dog 0, pivoted to the bracket o, engages said notches, as illustrated in Fig. 5 of the drawings. A rod'o is connected to said dog for throwing it out of engagement when desired.

It will be observed that by turning the shaft e the wires or ropes o are wound orunwound on the spools ff and cause the awning to be raised or lowered, as may be desired, and this operation is materially facilitated by the use of either the spring t' or weightj. These count-erpoises may be soadjusted as to cause them to automatically raise the awning as soon as the dog 0 is thrown out of engagement With the Wheel D.

It Will be noted that my invention dispenses with the usual pulleys or sheaves, which are liable to be torn from their fastenings, and

the awning.

gathered in folds in the operation of raising \Vhat I claim as my invention is The combination, with the awning-cloth attached at its upper edge to stationary fastenings on the building, the frame pivoted to the building and connected to the lower end of said cloth, mechanism for -raising said frame, the revoluble shaft beneath said upper fastenings, and spools attached to said shaft, of hoisting-ropes extending from said spools directly to the aforesaid pivoted frame, and a guard disposed over the aforesaid shaft to receive upon its exterior the folds of the raised aw ning-cloth substantially as set forth.
