- This invention relates to windmills, and has for its object the production of a windmill of novel form wherein the wind passing through the wheel is used to the best advantage and wherein no directing vane or tail is necessary to hold the wheel to the wind.
- a suitable directing member having a body which tapers from its base to its point to form a substantially conical or pyramidical shape, which body is mounted for turning movement about a vertical axis.
- the windwheel is preferably supported by the said directing member and is mounted to rotate about a horizontal, axis as usual, said wheel being situated at the. base of the conicalshaped directing member and having its sails situated outside of the base.
- the apex of the directing member points toward the wind, and the directing member has two functionsfirst, to hold the Wind-wheel to the wind, and, second, to divert the wind, which would natually pass through the center of the wind-wheel and which would furnish comparatively little power because of the short lever-arm through which it would work, to the sails which are situated some distance from the axis of the wheel and which therefore work through a comparatively long lever-arm.
- the directing member is preferably made hollow and incloses within itself the mechanism connecting the wind-wheel with the power-shaft, thus protecting the same.
- Figure 1 is a vertical central section of my improved windmill.
- Fig. 2 is rear elevation thereof.
- Fig. 3 is a detail showing two positions of one of the sails.
- Fig. 4 is a section on the line was, Fig. l; and
- Fig. 5 is a modified form of my invention.
- One of the novel features of the present invention consists in supporting the windwheel in bearings carried by a directing member which is mounted upon a tower for movement about a vertical axis and which takes the place of the ordinary tail orvane and serves to hold the wind-wheel to the wind.
- the directing member which I have herein chosen to show is hollow and comprises a substantially cone-shaped shell 15 and the strengthening or stiffening spider or strut member 20, which is situated at the base of the shell and serves to preserve its shape.
- the directing member may be mounted on the tower for movement about a vertical axis in any suitable way, and, as herein shown, I have provided asupporting-spider 22, which is attached to the lower end of the shell and which has a hub 23, encircling a stand 16, rigid with the tower 3, the said hub resting and turning upon a collar 24.
- asupporting-spider 22 which is attached to the lower end of the shell and which has a hub 23, encircling a stand 16, rigid with the tower 3, the said hub resting and turning upon a collar 24.
- the Wind-wheel is carried upon a suitable shaft 4, which in turn is mounted upon bearings supported by the directing member, the saidshaft having a bevelgear 5 thereon, which meshes with a bevel-gear 6 on the power-shaft 7.
- the latter shaft is supported in any suitable bearings in the tower and is illustrated as passing through the .stand 16.
- the upper end of the power-shaft is supported in a bearing 18, carried by arms 19, extending from the strut 20, the lower end of the bearing being illustrated as setting in and turning in a socket in the upper end of the stand 16.
- the bearings for the shaft 4 may be supported by the directing member in any suitable way, and, as herein illustrated, the shaft extends the full length of the directing member and has one end journaled in a bearing or block 26 at the apex of the directing member, while the other .endpasses through and is journaled in the spider 20 of said directing member.
- the wind-wheel comprises a central head 8, preferably having a spider-like construction, though my invention would not be departed from if this head were in the form of a disk.
- the sails 9 Secured to the head 8 and extending beyond the periphery thereof are the sails 9, which are preferably pivoted to the head and are substantially U shape in cross-section, each sail thus having two blades 10.
- Each sail is shown as supported by a suitable shaft 11, which in turn is carried by bearings 12 upon the head 8, said shaft forming an axis about which the sails may be turned to bring them more or less into the wind.
- the lower end of each shaft 11 is offset or cranked, as at 13, and the crank portion rests against a suitable controller 14, slidably mounted upon the shaft 4.
- the controller is illustrated as having a tapered body and will preferably be substantially cone shape. By moving the controller back and forth upon the shaft the inclination of the sails to the wind may be varied, as will be obvious. While I have herein shown a conical controller, yet my invention would not be departed from if a controllcr of any other form were used, it only being necessary that the controller should have such a shape and such connection with the offset portions of the shaft as to control the position of the sails through the shaft.
- the directing member is supported by the tower, and the wind-wheel in turn is supported by the directing member.
- the directing member has a long and comparatively slender body, as will be seen, and by placing the vertical axis thereof in the position shown and the wind-wheel at the base of said member the directing member serves to hold the wind-wheel to the wind and performs the function of the usual vane or tail.
- the directing member serves as a housing for the gearing and shaft and also as a means for diverting the wind, which would naturally pass through the center of the wheel and which would perform no work to the sails where it can be most economically used.
- the body of the directing member may either be conical shape or pyramidical shape, it only being necessary that it have a tapering body.
- I have illustrated the said directing member as having its surface fluted or scalloped, as shown in Figs. 2 and 4, and as provided with the stiffening members 28, which serve to give proper shape to the shell, which may be of metal or any other suitable material.
- the fluted or scalloped surface 15 of the member forms ridges 29, which assist somewhat in holding the said member steadily to the wind.
- a deflecting-flange30 which encircles the directing member and directs the wind directly to the sails.
- the controller 14 may be operated in any suitable way, and I have herein illustrated the same as having connected thereto the rack 31, which passes through the member 20 and is supported by a suitable bearing 32, through which also the shaft 4 passes, the said rack meshing with a pinion 33, carried by the member 20.
- the pinion 33 will be operated by means of a cord or other connection 34, which is connected to a crank secured to the pinion, the said cord or connection being led to any convenient place within reach of the operator.
- the pinion When the said cord is pulled upon, the pinion will be rotated and through the rack will move the controller to the right, thereby turning the shafts 11 and swinging the sails 9 in an inclined position with reference to the direction of the wind, the extent of the inclination of the sails being under the control of the operator.
- the cord 34 will be suitably secured, and the force of the wind against the sails will operate to hold the cranked portions of the shaft 11 hard against the controller 7. hen it is desired to throw the wind-wheel out of operation, the cord 34 is merely released, when the force of the wind against the sails will throw them around into a position parallel with the direction of the wind, as shown in dotted lines, Fig. 3.
- the full-line position of the sails in Fig. 3 shows approximately the working position thereof, and it will be seen that the front and rear ends are cut so as to stand parallel with the base when the sails are in this position.
- Fig. 51 have illustrated a slightly-modilied form of my invention wherein the directing member rotates with the sails.
- the directing member is designated by 15, and the sails are in the nature of spiral blades 9, which are fast to the surface of the cone.

SPECIFICATION forming part of Letters Patent No. 762,315, dated June 14, 1904.
Application filed March 10, 1902. Serial No. 97,443. (No model.)
To a, whom it may concern:
Be it known that I, JOSEPH L. J OYOE, a citizen of the United States, residing at Egremont, in the county of Berkshire and State of Massachusetts, have invented an Improvement in Vindmills, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.
This invention relates to windmills, and has for its object the production of a windmill of novel form wherein the wind passing through the wheel is used to the best advantage and wherein no directing vane or tail is necessary to hold the wheel to the wind.
In accordance with my invention I provide a suitable directing member having a body which tapers from its base to its point to form a substantially conical or pyramidical shape, which body is mounted for turning movement about a vertical axis. The windwheel is preferably supported by the said directing member and is mounted to rotate about a horizontal, axis as usual, said wheel being situated at the. base of the conicalshaped directing member and having its sails situated outside of the base. The apex of the directing member points toward the wind, and the directing member has two functionsfirst, to hold the Wind-wheel to the wind, and, second, to divert the wind, which would natually pass through the center of the wind-wheel and which would furnish comparatively little power because of the short lever-arm through which it would work, to the sails which are situated some distance from the axis of the wheel and which therefore work through a comparatively long lever-arm. The directing member is preferably made hollow and incloses within itself the mechanism connecting the wind-wheel with the power-shaft, thus protecting the same.
I have also devised a special form of sail for my windmill which has many advantages.
In the drawings, Figure 1 is a vertical central section of my improved windmill. Fig. 2 is rear elevation thereof. Fig. 3 is a detail showing two positions of one of the sails. Fig. 4 is a section on the line was, Fig. l; and Fig. 5 is a modified form of my invention.
One of the novel features of the present invention consists in supporting the windwheel in bearings carried by a directing member which is mounted upon a tower for movement about a vertical axis and which takes the place of the ordinary tail orvane and serves to hold the wind-wheel to the wind. The directing member which I have herein chosen to show is hollow and comprises a substantially cone-shaped shell 15 and the strengthening or stiffening spider or strut member 20, which is situated at the base of the shell and serves to preserve its shape. The directing member may be mounted on the tower for movement about a vertical axis in any suitable way, and, as herein shown, I have provided asupporting-spider 22, which is attached to the lower end of the shell and which has a hub 23, encircling a stand 16, rigid with the tower 3, the said hub resting and turning upon a collar 24. The above construction, however, is only one out of many ways in which the directing member could be mounted upon the tower for turning movement, and I do not wish to be limited to any particular way of accomplishing this. The Wind-wheel is carried upon a suitable shaft 4, which in turn is mounted upon bearings supported by the directing member, the saidshaft having a bevelgear 5 thereon, which meshes with a bevel-gear 6 on the power-shaft 7. The latter shaft is supported in any suitable bearings in the tower and is illustrated as passing through the .stand 16. The upper end of the power-shaft is supported in a bearing 18, carried by arms 19, extending from the strut 20, the lower end of the bearing being illustrated as setting in and turning in a socket in the upper end of the stand 16. The bearings for the shaft 4 may be supported by the directing member in any suitable way, and, as herein illustrated, the shaft extends the full length of the directing member and has one end journaled in a bearing or block 26 at the apex of the directing member, while the other .endpasses through and is journaled in the spider 20 of said directing member.
The wind-wheel comprises a central head 8, preferably having a spider-like construction, though my invention would not be departed from if this head were in the form of a disk. Secured to the head 8 and extending beyond the periphery thereof are the sails 9, which are preferably pivoted to the head and are substantially U shape in cross-section, each sail thus having two blades 10. Each sail is shown as supported by a suitable shaft 11, which in turn is carried by bearings 12 upon the head 8, said shaft forming an axis about which the sails may be turned to bring them more or less into the wind. The lower end of each shaft 11 is offset or cranked, as at 13, and the crank portion rests against a suitable controller 14, slidably mounted upon the shaft 4. The controller is illustrated as having a tapered body and will preferably be substantially cone shape. By moving the controller back and forth upon the shaft the inclination of the sails to the wind may be varied, as will be obvious. While I have herein shown a conical controller, yet my invention would not be departed from if a controllcr of any other form were used, it only being necessary that the controller should have such a shape and such connection with the offset portions of the shaft as to control the position of the sails through the shaft.
From the above description it will be seen that the directing member is supported by the tower, and the wind-wheel in turn is supported by the directing member. The directing member has a long and comparatively slender body, as will be seen, and by placing the vertical axis thereof in the position shown and the wind-wheel at the base of said member the directing member serves to hold the wind-wheel to the wind and performs the function of the usual vane or tail. In addition to this function the directing member serves as a housing for the gearing and shaft and also as a means for diverting the wind, which would naturally pass through the center of the wheel and which would perform no work to the sails where it can be most economically used. The body of the directing member may either be conical shape or pyramidical shape, it only being necessary that it have a tapering body. In the drawings I have illustrated the said directing member as having its surface fluted or scalloped, as shown in Figs. 2 and 4, and as provided with the stiffening members 28, which serve to give proper shape to the shell, which may be of metal or any other suitable material. The fluted or scalloped surface 15 of the member forms ridges 29, which assist somewhat in holding the said member steadily to the wind. In order that the wind which is diverted or deflected by the directing member may all pass through the sails instead of between the sails and the surface of the cone member, I will preferably employ a deflecting-flange30, which encircles the directing member and directs the wind directly to the sails.
The controller 14 may be operated in any suitable way, and I have herein illustrated the same as having connected thereto the rack 31, which passes through the member 20 and is supported by a suitable bearing 32, through which also the shaft 4 passes, the said rack meshing with a pinion 33, carried by the member 20. The pinion 33 will be operated by means of a cord or other connection 34, which is connected to a crank secured to the pinion, the said cord or connection being led to any convenient place within reach of the operator. When the said cord is pulled upon, the pinion will be rotated and through the rack will move the controller to the right, thereby turning the shafts 11 and swinging the sails 9 in an inclined position with reference to the direction of the wind, the extent of the inclination of the sails being under the control of the operator. After the sails have been properly set the cord 34 will be suitably secured, and the force of the wind against the sails will operate to hold the cranked portions of the shaft 11 hard against the controller 7. hen it is desired to throw the wind-wheel out of operation, the cord 34 is merely released, when the force of the wind against the sails will throw them around into a position parallel with the direction of the wind, as shown in dotted lines, Fig. 3. The full-line position of the sails in Fig. 3 shows approximately the working position thereof, and it will be seen that the front and rear ends are cut so as to stand parallel with the base when the sails are in this position.
In Fig. 51 have illustrated a slightly-modilied form of my invention wherein the directing member rotates with the sails. In this embodiment of my invention the directing member is designated by 15, and the sails are in the nature of spiral blades 9, which are fast to the surface of the cone. The cone has rigid therewith a bevel-gear 5, which meshes with a bevel-gear 4 upon the power-shaft 7 The shaft which supports the wind-wheel will be supported in some suitable way. (Not shown.)
From the above it will be observed that my invention consists, broadly, in providing a cone-shaped directing member which is supported by a tower in such a way as to have a movement about a vertical axis and which in turn furnishes the sole support for the windwheel.
While I have described one specific embodiment of my invention, I do not wish to be limited to the precise construction herein shown, as various changes may be made in the shape and arrangement of the parts without departing from the spirit of my invention as expressed in the appended claims.
