AWNING.

SPECIFICATION forming part of Letters Patent No. 593,147, dated November 2, 1897'.

Application led April 28, 1897. Serial No. 634,263. (No model.)

To @ZZ whom t 7am/ 1f concern:

Beit known that I, Mnn'rnv F. VIEDEMANN, a resident of Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Awnings; 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 appertaius to make and use the same.

My invention relates to an improvement in awnings, the object being to provide an awning designed more especially for use on buildings with low fronts where it is desirable to have a large extent of awning and where the height of the building will not permit of the use of an ordinary rod, and also for general use where lit is desired to have a large extent of awning.

A -further object is to provide an awning which will be automatic to the extent that it will open itself when the awning is released.

Vith these objects in view my invention consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view showing the awning lowered. Fig. 2 shows it raised, and Fig. 3 is a detailed view.

A. represents a guide or slide rod.. There are at least two of these, as shown, secured vertically to the side of the building to which the awningis to be attached, one at either end ofthe space to be covered by the awning, and if more than two arms are deemed necessary to give proper support and solidity to the awning when lowered then there will be as many additional guide or slide rods as additional arms. Y

The awning-frame consists of a lazy-tongs construction pivoted to the stationary bracket or hinge l at the lower end and to the bracket or jaw-slide which moves on the slide or guide rod A at its upper end. The bracket or jawslide l and the guide or slide rod A may be constructed out of one solid piece or they may be separated. The jaw-slide 2 may have a shcave in the back to run on the rear side of the slide or guide rod A in order to reduce friction to a minimum.

The several bars of the lazy-tongs are pivotally connected together in the usual manner. The ends, however, may project a short distance beyond the pivotal points, as 3 3, in order to provide additional bearing.

The outer bar or arm 5 of the lazy-tongs is extended outward any desired distance. The length may of course be varied, but preferably this bar or arm extends approximately from the lower end of the lazy-ton gs when folded up, as shown in Fig. 2, to the roll around which the awning runs, or in case no roll is used then to such a height that the awning-pole will be brought nearly in contact with the place on the building to which the upper part of the awning is fastened.

The outer bar or arm 5 may also from its connection with the other bar of the lazytongs be curved outward, so that the awning-pole will be thrown in the same horizontal plane with the brackets on the building or even lower when the awning is lowered.

The lazy-ton gs are in general disposed horizontally when in the lower position, although the device will work as well in an oblique position, and I therefore do not wish to confine myself to such a construction as to limit the said lazy-tongs to a horizontal disposition.

The lazy-tongs are made to reach outward a long or short distance, as the case may be, by simply varying the length of the bars in the lazy-tongs or by varying the number thereof, a greater length of bar or more bars being used when it is desired to project the awning farther and a shorter length of bar or a less number of bars when not so far.

Several advantages are possessed by the present construction over others disclosed by the prior state of the art. l-Ieretofore it has been necessary to have the lazy-tongs obliquely disposed. In the present invention such disposition may be either oblique or horizontal.

The present invention has all the advantages of the oblique lazy-tongs-that is, it has the benefit of the force of gravity in assisting to lower and spread the awning. It also has the added advantage of extending out horizontally so that side curtains can be used to advantage, whereas with the oblique construction and a roller side curtains can be used. Again, no mechanism of lever or other construction is required to lower the IOO awning. When the awning is released, it drops to anyV position desired, and the long outer arm or bar assists in lowering the awning. Moreover, it will be observed that the sliding part is above, Whereasheretofore it has been below, the advantage being that the present construction is very compact, less liable to get ont of order, and absolutely automatic. In addition, should the sliding part be below, as heretofore, the tendency ofV the lazy-tongs will be to close up, thus throwing the awning against the building, which defect has heretofore been overcome by the lever mechanism above spoken of or by placing the lazy-tongs in an oblique position, both of which objections the present construction overcomes.

It is evident that slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the eXact construction herein set forth.

Having fully described my invention, what I claim as new, and desire to secure by Letters guide-rods, of lazy-tongs having a stationary pivot below the guide-rods and a sliding connection with the guide-rods.

2. In an awning the combination with guide-rods, of lazy-tongs each having a sta tionary pivot below its guide-rod and a slidin g connection with its guide-rod, the outer upwardly-exten ding bars of the lazy-ton gs being of Ygreater length than any of the other bars.V substantially as and for the purpose set forth.

3. In an awning, the combination with vertical guide-rods, and a slide mounted to move up and down thereon, said slide provided with an antifriction-roller to lessen or prevent friction, of lazy-tongs, one end of which is pivoted to the slide and another at a point below the guide whereby the weight of the ton gs is taken advantage of to cause the awning to lower and spread.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

MARTIN F. WIEDEMANN.
