COMBINED WINDMILL DERRICK AND RESERVOIR.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed February 17, 1912. Serial No. 678,249.

To all whom-it may concern:

.Be it known that I, Osonn F. EluosoN, a citizen of the United States, residing at Stratford, in the county of Hamilton and State of Iowa, have invented certain new and useful Improvements in Combined Windmill Derricks and Reservoirs, of which the following is a specification.

This invention relates to wind mills and has for an object to provide a wind mill having a derrick formed of tubing adapted to constitute a compressed air reservoir, the air compressor being situated at the top of the derrick and delivering compressed air into the tubular uprights of the derrick, the oon1- pressed air preferably being drawn olf from the combined derrick and reservoir through a valve controlled outlet preferably secured to one of the tubular uprights at the bottom of the derrick.

With the above object in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawing forming part of this specification :Figure l is a side elevation of the device. Fig. 2 is a cross sectional view taken on the line 2-2 Fig. 1. Fig. 3 is a longitudinal sectional view taken on the line 3-3 Fig. 1.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates .tubular uprights and 11 designates cross braces connecting the uprights, there being preferably four uprights eonver ing toward the upper ends,

each upright being formed of short tubular sections connected together by fourway unions 12, the cross braces being tubular and connected to the uprights through the instrumentality of the four-way unions as clearly shown in Fig. 2. In this manner continuous intersecting ducts are presented so that the derrick formed by the uprights and cross braces, constitutes a reservoir.

A, wind wheel 13 having a shaft 14 equipped with a vane plate 15, is supported upon the derrick through the instrumentality of a pedestal 16 the latter in the present instance being hollow and shown projecting through a platform 17 which connects the upper ends of the uprights and being swivelly secured to a pair of the cross braces 17 below the platform as shown at 17". The shaft 14 is equipped with a pinion 18 over which and a sprocket gear 19 a sprocket chain 20 is trained, the sprocket gear 19 being fixed to a crank shaft 21 which is journaled in a bearing 22 carried 11 on the pedestal 16. An air compressing cy inder 23 is secured to the pedestal 16 through the inst-rumentality of a bracket 24, and the piston 25 of the cylinder is connected with the crank 26 of the crank shaft through the instrumentality of a pitman 27. A feed pipe 28 connects the cylinder with the hollow pedestal as shown. Upon actuation of the piston through the instrumentality of the crank shaft, air will be compressed and fed into the combined reservoir and derrick. For drawing oil the compressed air, an outlet pipe 29 controlled by a valve 30 is secured to the lower end of one of the uprights as shown. This pipe may be connected to a compressed air engine shown conventionally at 31 or to other desired machinery.

It is known that a cylindrical reservoir or tank has been previously used to support a wind mill equipped with an air compressor for storing air in the reservoir, however the present invention is designed to obviate the disadvantages oi this type of reservoir, by providing a SkklQtOIl derrick formed on tirely of intersecting pipes rconnected together, this structure :to-tming'.a skeleton reservoir which will be strong and will offer the least resistance to heavy winds and the like.

\Vhat is claimed, is: 5

A wind mill including a skeleton reservoir formed of upright tubes and cross't ibcs connectingsaid upright tubes, a plat orm connecting the upper ends of said upright tubes, a wind wheel above said platform, a

and a conductor pipe connecting said pump with said pedestal.

In testimony whereof I affix my signature, in the presence of 0W0 witnesses.
