IMPROVEMENT IN SAWING WOOD BY WIND-POWER.

Specification forming part of Letters Patent No. 43,941, dated August 23, 1864.

To all whom it may concern:

Be it known that I, JOEL WIsNER, of East Aurora, in the county of Erie and State of New York, have invented a new and useful Improvement in Machines for Sawing l/Vood by Wind-Power 5 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciciitioii, in which- Figure 1 is a side elevation of my machine, showing the foundation in section. Fig. 2 is an elevation giving a direct front View of the wheel. Fig. 3 is a horizontal section on the linemx of Fig. 2, exhibiting a plan of the platform and indicating by red lines the method of regulating and stopping the motion.

Like letters designate corresponding parts in all of the gures.

My invention has for its object the adaptation of a windmill of simple construction to the use of farmers and others for sawing logs and wood, so as to be economical in cost,easily managed 5 and it consists in the arrangement of the wind-wheel and sawing apparatus upon a revolving table, and regulating' and controlling the motion by turning the same to different angles relative to the wind, and also in the construction of the wheel.

As represented in the drawings, A is a vertical standard, to which the platform or table B and cross-piece C are attached. The lower end ol' this standard is made round, as at A, and passes through a timber or plank, D, resting'on or near the surface of the ground, or other suitable foundation, terminating in a steel point, which has a bearing in the step E, which may be of iron or other suitable inaterial, so that the standard may turn with but little friction. Ordinarily a small well may be sunk in the ground, either Walled or boxed up, and the step E let into a timber or masonwork at the bottom, as in Fig. 1. The crosspieee O on the top of the standard forms a support for the boxes a a of the'shaft F of the wind-wheel. .lt is also supported by another standard, G, having its foot in the platform B, and from this the arm H, sustained by braces b b above and below, extends horizontally outward, and forms a bearing for the pitman lever I, the upper end of which is connected the lower end carries the reciprocating saw L. On the platform B are suitable bearings, c c, on which to laythe log or wood Mto be sawed. The wind-wheel consists of four radial arms, h h, from the shaft F, each provided with an oblong-square wing, O. These wings are set at an angle of forty-tive degrees with the arms h, and also with the plane of the shaft F, the latter being parallel with the direction of the wind when the wheel is in operation. There is upon the back end of each wing a board or tiange,f, having an inclination of forty-tive degrees with the plane or face of the wing.

As the wind strikes or impinges on the face of the wing, this flange checks it, and deflects it suddenly in a backward direction, (relative to the rotation of the wheel,) so that a draft or reaction is produced that moves forward the wings with much greater force and rapidity than is the ease when the faces of the wings form an unbroken plane. Iuthis particular the operation resembles that of turbine water- Wheels. A wheel constructed in this manner will only operate to advantage when directly facing the wind, and by turning the standard so as to present it at an angle quartering to the wind the motion at once stops. I build these Wheels of so small a size (for the purpose ot' sawing wood) that a man or boy can easily swing them on the bearing of the pivoted standard A by placing the hand or foot to the platform B, and as it is necessary to frequently stop and remove the saw, I make the turning of the machine on the pivot A the means of stopping, starting, and regulating the motion, and as such it proves highly effective, safe, and economical, for it dispenses With much complicated mechanism which `would otherwise be necessary, and the stopping is instantaneous and'without strain to the parts, inasmuch as by changing the position of the wings to the wind the same force that was imparting motion to the wheel is employed to arrest it, and its application is at the same actuating points. It' the wind is strong and the motion of the wheel too rapid, it can be retarded by turning it'so as to present the face less squarely to the Wind.

I make my wheels of smalldiaineter as being more easily managed and better adapted to the purpose, and by the described construcwith the shaft F by means ofthe crank K, and l tion of the wings I get a rapid motion even in a moderate Wind7 and depend upon speed more thany power to accomplish the work expeditiously.

In operating, the attendant when a log is sawed through revolves the machine on its axis until the motion stops, when he raises the saw and hangs it on the pin s,I `ig.1, as shown in red lines in Fig. 2. l

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A Wind-wheel constructed with the fia-t wings O and flanges f, in combination with the shaft F and pivoted standard A, con
