AWNING.

PECEEICATION forming part or `Letters Patent No. 356,833, dated February 1, 1887.

Application i'iled March 23, 1856. Serial Ifo. 196,203. (No model.)

To @ZZ whom t may concern.-

Be .it known that I, .lecon GREENBERG, of the city of Cincinnati, in the county of Hamiltou and State of Ohio, lieve invented certain new und useful Improvements inAWning-s, of which the following is e specification.

The object of my invention is to provide ineens whereby the mechanism for raising and lowering en owning can be made secure and fast, so that nieddlers or those evilly disposed may be prevented from tampering with the fixtures, ond nt the Sonie time permitting the drop of the owning to be :it any desired point and iiistening it tliereat.

My invention will he readily understood from the hereinafter description, and the eoeoinpanying drawings, forming part of my application, in which# Figure l is a side eleva-tion of an owning, showing the mechanism for raising and lowerering, arranged so as to he manipulated from the interior und having att-nehed my ret-nim ing device. Fig. 2 is n. front View of saine, showing the retaining-link in position and looked. Constructions of this kind are eniployed when the awning is raised or lowered from the outside. Fig. 3 is aside View of Fie". 2. Fig. fi represents n medido-ation of the retaining-link ond the Way the operating-axle is made.

A represents the house to which the owning and its proper lixtures are attached.

B is the show-Window.

G is the casing or drum containing the lower sprocket-Wheel, on and between which and s corresponding upper wheel the endless chain D is carried and operated. This lower Wheel is mounted on the sheft or axle o, which carries also the beveled gear 7i. i is n, corresponding bevel-geur mounted upon the end ofthe sheft E, the lutter being supported in proper hearings und running through the Wall into the interior, Where n ernnl; or other suitable device can be attached for operating it. The gears la i nre arranged so es to mesh into each other, ns shown.

The end to which the crank is attached is squared or otherwise formed, so that it will not be round, but zuigulnr-shnped-in other Words, polygonal. To any Convenient portion of the premises, and in o line with this polygonal portion, is pivoted n retaining link or pewl, P, (seen more clearly in Fig. 2,) so that it can be brought'J into Contact with seid angular portion or polygon.

F is the roller on which the canvas E or other owning material is Wound und nnwonnd.

I is thelongitudinnl rod to which the lower portion of the canvas is secured. M is one of the side hars, rigidly secured et one end to seid longitudinal rod, the other end being pivoted to an nrni, O, attached to the side of the house. This freine or support, consisting oi' the side bars, M, and the longitudinal nur I, rises und falls proportionately with the canvas. The free end of the retaining-link is provi ded with an eye, through which nud n staple, Sniixed to the casing or other convenient place, the loow of n padlock is inserted, und by means whereof the link is held rigidly in position, ns shown. Constructions of this kind, as shown by Fig. l, ure used when the awning is to be operated from the interior; butwhere itis desired to reise nud lower from the outside I arrange the devices as shown in 2 and 3. In the latter ense the boxing or drum C is atteohed in any Convenient way to the side of the house, and the end of the axle E, being polygonal, as before stated, entends out beyond the face of the casing, so as to permit of the at tachnient ol' the crunk,

To the ffice of the ensing is fastened 'die retaining-link I?. It will ne noticed that this retaining-link is provided with :i heel which has n. degree ofonrvatnre. Then the link is drown over the shaft E und looked, us shown in Figs. 2 and 3, it holds the shud; permanently and prevents its being turned; for, should en nttempt he mede to unwind, or the owning by its own Weight should have it tendency to unwind, thelinl: would check it, for any heck- Wsrd movement would enuse the shaft E to bind or Wedge into the heel ol' the link Il?, thereby stopping all further progress und zioeomplishing the desired result. The liul; performs the seme service in constructions suoli as are shown in Fig. l.

Instead of having the etnie or shaft E ingular or polygonal, nsjustdesorihed, ond the heel of the linl; constructed so that it will wedge the axle, I muy provide the uxle with s ratchet and the link with n tooth. to operate in the ICC) ratchet, as seen in Fig. 4. This modification accomplishes just the same functions as the construction rst described-viz., of stopping the axle at any desired point-so that the reach7 of the canvas can be proportionally large or small.

Another modification which is within the scope of my invention is to provide the link l? at about the point where the tooth is, as seen in Fig, 4, with a notch or slot and the axle with teeth to engage and disengage with the slot in the link. This would be but practically reversing the mode as illustrated in Fig. 4, for then the axle would be provided with a series of pawls to engage with the notch in the link, instead 'of using one pawl to engage with the ratchet-teeth. It will be seen that I have thus provided mea-ns for holding the axle, and through it the awning itself, at any desired point, which means are simple, cheap, and effective.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. 'In a device for operating awnings, the combination, with a shaft provided with teeth 0r angular projections and with means for rotating the shaft, ofa link or bar pivoted at one end and adapted to engage with the shaft, and a looking device adapted to be applied to the free end of the link or bar and to a fixed eye or loop, substantially as shown.

2. In a device for operating awnings, the combination of an operating-shaft having an angular periphery, a iiXed eye or staple, a piv oted bar adapted to engage with the operatingshaft, and a device, substantially such as shown, to lock the pivoted bar to the eye or staple and thereby hold the bar in engagement with the shaft.

3. In a device for operating awnings, in combination with a framing, a shaft j ournaled therein, a link or bar pivoted to the framework and adapted to engage with the shaft, and a locking device, substantially such as shown, to lock the link or bar toan eye or to the framework andv thereby holdthe bar in engagement with the shaft.

4. In a device for raising and lowering awnings, the combination of an operating-axle provided with teeth, and a retaining-link to engage with same, the link having on its free end an eye by means of which and a properlyaffixed ring or staple means are afforded for securing the link, substantially as shown and described, and for the purposes noted.

5. In combination with an awning, a roller upon which said awning is wound, a shaft below the roller provided with a gearwheel,an endless band connecting the shaft and roller, a second shaft at an angle to the rst one provided with a gear-wheel to mesh with the gear on the first shaft and provided with a handle, a pivoted link or bar adapted to engage with the second shaft, and a lock applied tothe link or bar and to an eye secured to the framework to hold the bar in engagement with the second shaft.
