SPECIFICATION forming part of Letters Patent No. 614,233, dated November 15, 1898. Application filed October 18, 1897. Serial No. 655,514. (No model.)

To all whom itimay concerm, v

Be it known that I, LA VERNE W. NOYES, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof-Illinois, have invented a certain'new and useful Improvement in Windmills, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. V

My invention relates to a windmill, my object being to provide an improved form of mill whereby the construction may be greatly simplified and whereby the operation of the mill may be improved'and rendered more effective.

I have illustrated my invention in the accompanying drawings, in which- Figure 1 is a plan view of the mill of my invention. "Fig. 2 is a view thereof in elevation. Fig. 2. Fig. 4: is a sectional view on line 4 4, Fig. 3. Fig. 5 is a plan view of the turn-table or barrel of the mill. Fig. 6 is a sectional view on line 6 6, Fig. 1. Fig. 7 is a sectional view on line 7 7, Fig. 1. Fig. 8 is a sectionalview on line 8 8, Fig. 5, showing the wheelshaft in position. Fig. 9 is a sectional View on line 9 9, Fig. 6. Fig. 10 is a sectional View on line 10 10, Fig. 6. Fig. 11 is a sectional view on line 11 11,'Fig. 6. Fig. 12 is a plan view of the casting carried upon the'tower for supporting the barrel of the mill.

Like letters refer to like parts in the several figures.

Upon the upper end of the tower on is car-.

ried the supporting-barrel a, which carries a shoulder a which forms a bearing-surface for the rollers a a upon which the turn-ta ble or barrel 1? rests. the barrel b is carried the detachable frame or support 0, which is secured in position by means of the bolts 0 c c. In order to remove the strain from the bolts due to the tendency of the casting a to rotate during the operation of the mill, a lug b is provided upon the casting 19, with which a lug 0 carried upon the casting a, is adapted to engage, to thus-withstand any tendency of the casting c to rotate.

J ournaled in the sleeve b of the casting b is the wheel-shaft d, upon the end of which is mounted the spider dof the wind-wheel.

Fig. 3 is va sectional view on line 3 3,-

Upon the upper end of A roller-bearing formed by the rollers d d",

Fig. 8, is formed between the sleeve 5 and the wheel-shaft d.

A similar roller-bearing is formed by means of .the rollers d d between the forward end of the sleeve b and the wheelshaft d, Fig. 7. In order to take up the thrust of the wheel, rollers d d are provided between the end of the sleeve b and the spider d, Fig. 7. To afford a bearing-surface upon the end of the sleeve 19*, I preferably provide a ring 6 which is secured to'the end of the sleeve b and extends inwardly toclosely surround the shaft (1, and thus provide an extended bearing-surface for the roll- Upon the end of the wheel-shaft d is mounted the gear-wheel e, which meshes with the pinion e, mounted upon the shaft e jour* nale'd in the sleeve 0 of the casting a by means of the rollers c at the opposite ends of said sleeve. Upon the opposite end of the shaft e is mounted the bevel-gear a which meshes with the bevel-pinion 6 carried upon the vertical shaft J", said shaft being journaled between the rollers 6 above the pinion and between the rollerse. below the same, said rollers being mounted Within the casting 0. Upon the ends of the sleeve 0 are provided the beads or raised ridges c 0", and the overhanging gears e and'e? overhang the same to prevent water from passing to the bearings between the shaft and the sleeve.

A collar f surrounds the shaft f just beneath the casting a and serves'as a support and bearing-face for'the cage carrying the rollers e". The lower end of the shaft f is ,journaled between the rollers f, which rest within the box f having a shoulder which rests upon the cylindrical portion g of the supporting-casting g, to which the lower end of the barrel a is screwed. Upon the lower end of the shaft f is carried the inner member 71. of a coupling, the outer member h of which is carried upon the upper end of the shaft is, which extends downward and imparts motion to the machinery to be driven by the windmill. The form of the members of the coupling is illustrated in Fig. 11, the inner coupling it being oblong and fitted within a corresponding recess or opening in the member h, whereby the members of the couplingrotate together, while at the same time they may be separated by moving the same longitudinally relatively to each other. The upper end of the member h is limited in its upward movement by the lower end of the cylinder g of the casting g, and a space is left between the lower end of the member h and the upper end of the member 71/, whereby any upward thrust of the shaft is will be resisted by the casting g and will not impart an upward thrust to the shaftf to endanger or break the gears of the driving-train.

The barrel or casting b carries arms b and 12 to which the bonel and brace Z of the tail are respectively pivoted, the pivots being so arranged that the tail has a tendency to assume the position wherein it is parallel to the wheel. Thefurl-lever m is pivoted at m and carries an arm m which is connected by a coiled spring m with the bone Z of the tail. Upon the lower face of the furl-lever is provided a lug m which engages the edge of the bone Z of the tail to start the same out of the wind and which is adapted to engage a notch Z in the edge of the bone Z when the tail is parallel to the wheel to lock the tail in the inactive position. To the furl-lever is attached the furl-chain n, by means of which the furl-lever may be rocked to swing the tail into its perpendicular position, as shown by dotted lines in Fig. 1. The furl lever carries an arm m which is adapted to encircle the driving mechanism of the mill when the tail is in the perpendicular position and is adapted to engage the brake-pin 0, which is secured to the brake-disk o, and to retract the same against the tension of the coiled spring 0 to move the brake-disk out of engagement with the flange of the spider. The furl-lever thus serves to throw off the brake at the same time that the wheel is thrown into the wind. The brake-disk 0' slides back and forth on the bearing-sleeve W, a pair of longitudinal ridges b being provided on the sides thereof to prevent the rotation of the disk. lVhen the mill is out of the wind, the tail bone Z, Fig. 1, rests against the end of the wheel-shaft d, which thus forms a limiting stop.

The furling-chain n,-connected with the furl-lever, passes around the vertical roller 1t and the horizontal roller 71 and is secured at the lower end to the ring 1), into which is screwed the upper end of the pipe 29, which surrounds the shaft f. A flatbar 19 secured at the upper end of the casting 0, passes through the slot in the ring 19 to cause the ring to rotate with the casting c and the turntable or barrel 1), upon which said casting is carried. The pipe 19 carries at the lower end a flange p upon which rests the swivel-ring p carrying four radially-extending arms 13 19 19 19 which are preferably of such length as to engage the inner wall of the barrel a and prevent the pipe 19' from coming into contact with the rotating shaft f. The armsp p carry openings, within which are hinged the inturned ends of the bail r, the members 7" r of which pass downward through slots g pivoted in the lower wall of the casting 1. To the lower end of the bail r is attached the furling chain or wire 9, which preferably extends down one of the posts of the tower and is connected with any suitable handle, whereby the mill may be thrown into and out of operation. The bail due to the oblique pull thereon will partake of a lateral movement as the same is moved up and down, and the slots 9 are made of sufficient length to accommodate this lateral movement. The engagement of the members of the bail with the slots 9 prevents the rotation of the bail,

and consequently holds the swivel-ring 13 against rotation, while permitting the pipe 17' to rotate within the swivel-ring.

The operation of my invention is as follows: Motion from the wind-wheel is transmitted by the gear-wheel e to the pinion e and from the bevel-gear e to the pinion 6 thus rotating the vertical shaft f and through the engagement of the coupling 72 h rotating the shaft 70 to drive the driving mechanism or other machinery, as desired. WVhen the mill is in operation, the tail occupies the perpendicular position illustrated in dotted lines in Fig. l, and in this position the arm m of the furllever engages the rod 0 to maintain the brakeshoe out of engagement with the spider of the wheel. In Fig. l the position of the tail when the wheel is out of the wind is illustrated in full lines, in which case the tail-bone rests against the end of the wheel-shaft Z as a stop. In throwing the wheel into the wind the bail r, Fig. 6, is pulled down, carrying with it the swivel-ring p and the pipep, carrying at the upper end the ring p, to which the furlingchain is attached, and the furl-lever is rocked to the dotted position shown in Fig. 1, thus locking the tail through the agency of the coiled spring m So long as the bail 1* remains in the lower position the wheel is held in the wind, and upon the release of the bail the tail swings out of the wind and carries the arm m of the furl-lever out of engagement with the brake mechanism to permit the setting of the brake, and the lug Z on the furl-lever moves into engagement with the notch of the bone Z of the tail to lock the tail in position. Any change in the direction of the wind during the running of the mill causes the turn-table or barrel 1) to rotate, and the flat bar 19 engaging the slot in the ring of the furling device, causes the pipe 1') to rotate with the barrel.

When it is desired to remove the driving mechanism for repair or other purpose, the bolts 0 c a may be removed and the casting raised vertically to withdraw the shaft from the barrel. In raising'the shaftfthe coupling h upon the end thereof engages the lower end of the box f carrying the roller-bearing, and raises the same out of its seat. As the raising of the shaft continues the box f engages the lower end of the pipe 19, thus raising the same with the remainder of the furlin g mechanism. By detaching the furling-chain n from the ring 10 or from the furl-lever the furling-pipe, the swivel-ring, and the bail may be removed from the barrel with the shaft, the loop of the bail passing through the opening of the'casting as the bail is raised.
