SPECIFICATION forming part of Letters Patent No. 510,435, dated December 12, 1893. 1'

Application filed February 25, 1893. Serial No. 463,730- (No model.)

To all whom it may concern:

Be it known that I, JOHN H. MILLER, a citizen of the United States, residing at Batavia, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in Windmill-Vanes, which is fully set forth in the following specification, reference being bad to the accompanying drawings, in which- Figure 1 represents a side elevation of my vane, showing its attachment to the main casting of the wind mill. Fig. 2 shows a plan of the reverse side of that shown in Fig. 1, of a portion of the vane. Fig. 3 shows a top view of the vane, cut in section, at line 33, Fig. 1. Fig. 4. shows a portion of the sheet metal when itis out ready to be attached to the frame or bone of the wind mill. Fig. 5 shows another portion of the same sheet metal out ready to be attached to the frame of the vane. Fig. 6 shows a perspective view of one end of the angle-iron cross-brace of the frame of the vane, the dotted lines showing the end turned down, ready to be bolted to the main frame or bone of the wind mill.

The object of my invention is to make a strong and inexpensive vane for a wind mill composed of metal.

My invention consists of the devices and combinations of devices hereinafter fully described and made the subject matter of the claims hereto.

In the accompanying drawings, A represents a portion of the main casting or turntable of a wind mill.

BB are two arms rigidly attached to or forming a part of the casting A to which the vane is pivoted at 0-0.

D is a vane-iron composed of a vertical piece, E, with two projecting arms or pieces, F-F, which are pivoted tothe arms BB, at C. There are also arms, GG, one above the other when the vane is in position on the mill, and to which the main frame or bone of the vane is bolted, and two arms or projections, HH, one under the other, to which one end of the braces for bracing the vane, is bolted. The main frame or bone, I, of the vane I make of angle-iron, extending around the vane of the mill, the ends being bolted to the projections or arms GGr of the vane iron D.

I have also an angle-iron cross-brace J. One side of this angle-iron is made longer than the other, as clearly shown at K in Fig. 6, and bent down as shown by dotted lines, and then bolted to the main frame or bone I, as clearly shown in Figs. 1, 2, and 3.

L is a sheet-metal piece cut in form to be bent over one of the sides of the angle-iron frame or bone I of the vane and of the crossbrace, J, clearly shown in Figs. 1, 2 and 3. This sheet metal piece is cut at the corners, as shown in Figs. 4 and 5, for the purpose of fitting to the main frame or bone and crossbrace of the vane, and enabling the edge to be turned over one side of the angle-iron constituting the main frame and cross-brace of the vane. This sheet metal piece is secured to the frame of the vane by turning its edge over one of the sides of the angle-iron which constitute the frame--no riveting being required to hold it in place.

M-M are two braces, one end of each of which is bolted to one of the arms H of the vane-iron D, and the other end of each is bolted to one of the sides of the angle-iron frame or bone I of the vane.

The construction of the vane-iron D is such that the main frame or bone I is bolted to it at one side of a center line drawn through the center of the main casting of the mill and through the point where the vane is pivoted to the main casting, and the braces M brace the vane near its longitudinal center so as to give it great strength.

My vane is made very quickly by using angle-iron for the main frame or bone of the vane, as well as the cross-brace, and braces MM, and the sheet metal constituting the wind surface of the vane is secured to'the vane frame by turning its edges over and swaging them down, thus obviating the necessity of bolting.

I have alight, very strong and durable vane, susceptible of sustaining great wind without injury to the mill.

Having thus described the construction and operation of my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a wind mill vane, the angle-iron main frame or bone 1; the angle-iron cross-brace J, and the sheet metal piece L secured thereto by turning its edges over one side of the angle-iron frame, substantially as specified.

2. In a wind mill vane, the vane-iron or casting D having arms or projections F adapted to bepivoted t0 the main casting or turntable, the arms G--G to which the main frame of the vane is bolted, and the arms I-I-l-I to which the braces of the vane are bolted; the angle-iron main frame of the vane adapted to be bolted to the arms GG of the vane iron D; and the braces M-M bolted to the arms H-I-I of the vane-iron D and to the main frame or bone I of the vane, as specified.

3. In a wind mill vane, the angle-iron main frame or bone I; the angle-iron cross-brace J, with one side longer than the other, and bent at right angles and bolted to the main frame or bone I of the vane; the sheet metal piece L with corners cut and adapted to bend over the main frame and cross-brace, as specified 20 and shown.

JOHN H. MILLER.
