.WlND-IVIOTOR- SPECIFICATION forming partof Letters Patent No. 781,010, dated January 31, 1905.
' Application filed May 25, 1904. Serial No. 209,652.
To all whom it may concern:
Be it known that I, KIEFFER LINDsEY, a citizen of the United States, and a resident of Greater New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Wind-Motors, of which the following is a specification.
The subject of this invention is a novel wind-motor having more particularly in view an eflicient pressure-surface when in the path of the wind, but which surface will when moving in opposition to the wind be brought to a condltion whereby 1t Wlll incur or exercise the least possible resistance, the arrangement thus conducing to the development of power under conditions of high 'efiiciency.
There are other important features connected with the invention, which besides those alluded to are embodied in the novel construction and arrangement of parts set forth in the subsequentdetailed description and illustrated may be deemed advisable.
in the accompanying drawings, in which Figure 1 1s an elevational v1ew of the novel wind-motor embodying myinvent1on. Fig.
2 is a detail elevational view of certain parts appearing in Fig. 1, but viewed from a position at right angles to that represented in the latter figure. similar to Fig. 2, the blade-sections, however, being shown in the feathering position. Fig.
t is an enlarged sectional detail view of certain features connected with the devices provided for the adjustment of the blades by hand. Fig. 5 is a detail plan view illustrating a modified form of my wind-motor.
Similar reference characters are employed to designate corresponding parts in the several figures of ,the drawings wherein they same may be carried out to a wide extent.
Fig. 3 is a view somewhat The frame for pivotally carrying the bladesections is presented by inner bearings a and an outer vertically depending bar A, said latter bar being braced by a diagonally-disposed stay a, the upper end of which is connected with the shaft A.
C designates the horizontal bars, from which the blade-sections ,G depend, the pivotal support of the bars C being accomplished by making said bars preferably of wood and driving in the ends thereof metal pins 0, the projecting extremities of which revolubly rest in the inner bearings a and outer bar A, respectively.
It will be observed by reference to Figs. 2 and 3that arms 0 are carried by the bladesections and extend oppositely to permit their connection in series with a rod 0 the latter being in somewhat contiguous relation to the shaft A. At itslo'wer end the rod 0 is attached by the short flexible connection 42 with a collar d, splined on the shaftA to insure its revolutionwith the latter, and thus maintain the proper relation of saidcollar and its connection with respect to the blade-sections'C and their parts. Manifestly a vertical movement ofthe collar d will, through its chainand-rod connection with the blade-sections, occasion the latter to assume positions 'hori- Zontally parallel with each other, as indicated in Fig. 3, or permit said sections to hang pendent, whereby they will present an efiicientpres-v sure-surface. It will be appreciated that with the blade-sections in a position such as illustrated in Fig. 2 and opposed to the wind the lower free portion of said blade-sections will bear against the bars in nearest contiguity, the result being that such blade-sections will interpose a solid resistance to the wind, and thus cause the latter to act efiiciently in moving said blade-sections around to permit the revolution of the shaft A. It is important to state this point, that the connecting-rod 0 is of sufficient weight'as to almost balance the bladesections. Hence when the extent of the revolution of said sections is such as to bring them to a position wherein the Wind-pressure will act on the surfaces thereof. the reverse-of that previously referred to, under which condition the free portions of the sections will not bear against the bars, the action of the wind, assisted by the counterbalancing tendency of the rod 0 will obviously be such as to bring said blade-sections to the horizontal position, (in dicated in Fig. 3,) in which position they will offer practically no resistance to the air. The blade-sections are thus caused to automatically feather under highly satisfactory conditions.
With a view of providing for the sliding of the collar d in an efficient and simple manner such collar contains a peripheral groove d within which is engaged the flange c of a sleeve E, having lower perforated ears 6, within which are engaged the pins or projections f of the bifurcated end of a lever F, intermediately pivoted, as indicated at f, and at the outer end of said lever is a flexible connection f depending to a position rendering it accessible to permit the adjustment of'the bladesections by hand.
With a view of facilitating the stoppage of the motor, particularly when a strong breeze exists, the outer end of the lever F is attached to an endless cable 7" ,passing around upper and lower pulleys, the former of which (designated by f) is represented in Fig. 1 of the drawings.
In Fig. 5 a modified construction of the novel wind-motor is illustrated. In said view, G designates the top of the power-transmitting shaft, upon which is supported a guard or shield H, the supports or stays ii of which are so conditioned as to afford a clearance for a series of radial blade-sections I. In this construction the upper stay h is extended at the opposite side of the shaft G for carrying a fish-tail blade or governor for the purpose of retaining the guard or shield in proper position with respect to the wind. It will therefore be comprehended that during a part of the movement of the blade-sections the latter will be screened behind the guard or shield, and therefore not subject to the action of the wind-pressure; but upon said blade-sections moving between and clear of the stays /a to a position at one end and clear of the shield H they will immediately become subject to the pressure and moved to efleet the revolution of the shaft.
Either of the forms of my invention disclosed not only presents an eflicientwind-motor, but involves such simple arrangements of parts as to be comparatively inexpensive and not liable to get out of order.
I do not wish to be understood as limiting myself to the precise details and arrangements of parts shown and described, but reserve the right to all modifications within the scope of my invention.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. The combination in a wind-motor, of a power-transmitting shaft, a series of radiallydisposed and pivotally-depending blade-sections on said shaft and adapted to turn therewith, said blade-sections having oppositely-extending and angularly-disposed arms, and a rod connected with said arms and of sufiicient weight to nearly counterbalance the weight of the blade-sections.
2. The combination in a wind-motor, of a power-transinitting shaft, a series of radiallydisposed and pivotally-depending blade-seetions on said shaft and adapted to turn therewith, said blade-sections having oppositely-extending and angularly-disposed arms, a rod connecting saidarms in series, a collar splined on said shaft'and having a connection with said rod, a sleeve revoluble on said shaft and engaged with the collar to permit the revolution of the latter, but insure its partaking of the vertical movements of the sleeve, and a handoperated lever engaged with said sleeve for vertically moving the same and collar upon the shaft.
Signed at New York, in the county of New York and State of New York, this 7th day of May, A. D. 1904.
