JOHN BOISOLAIR, OF MONTREAL, CANADA.

WINDMILLQ SPECIFICATION forming part of Letters Patent No. 529,358, dated November 20, 1894.

Application filed June 2'7, 1 8 94:.

To aZZ whom, it may concern:

Be it known that 1, JOHN BOISOLAIR, acitizen of the Dominion of Canada, residing at the city and District of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Windmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has reference to that class of windmills having two wheels, and used for either working pumps or machinery and has for its object to provide a good, safe wind engine.

Referring to the drawings similar letters refer to similar parts throughout the several views.

Figure 1, is a front view. Fig. 2, is a plan view. Fig. 3, is a sideview shown part in section. Fig. 4:, is a section on line X X of Fig. 1. Fig. 5, is an enlarged section on the line Y Y of Fig. 2. Fig. 6, is a section on line Z Z of Fig. 1. Fig. 7, is a vertical section of a portion of the main shaft or section on line C. D. of Fig. 8; Fig. 8, a section on line A. B. of Fig. 7; Fig. 9, a plan view of the extreme top of the frame; Fig. 10, an enlarged front view of a portion of the working mechanism, and Fig. 11, is a part section on line F. F. of Fig. 1.

As can be seen on the drawings, my windmill consists of the rectangular frame G mounted on to the hollow column H which is provided with four vertical slots h, h, h, h, equally spaced on its circumference, and extending from h to 729, this column I1 being securely joined to a suitable frame J, and serving as a vertical shaft for the frame G which can turn around it, it being suspended on its upper end, by means of the cross piece g in any suitable manner. The rectangular, frame G, also has the cross piece g through which the column H passes, and the one 9 to the end of which the upright pieces g are secured by-means of bands of flat iron 9 in such a way that by forcing the two sides g toward each other, the bands g will slide on the end of the piece 9 and act as guides to keep the ends of the upright pieces in their right position. Now, I make use of the two Serial No. 515,843. (No model.)

ordinary wheels K and L, which are secured to the hubs 7t and Z, and rotate in contrary direction. There is however nothing new about this,but the way I have them mounted on the shaft M, I think new, and consists in having the one L loose onto it, while the one K is firmly secured to it by means of the set screw It or in any other suitable way, the hubs 7c and Z both being provided on their'outer extremities with the disk cranks k and Z, to which are joined the connecting rods and Z which actuate the cross heads N and O, by being joined to them at 70 and Z These cross heads N and 0 being triangular in form as shown on the drawings and having the pieces 07. and n joined to a collar W and the ones 0 and-0 joined to the one 0 and both formed as shown on the drawings and encircling the column H, they serving to actuate the connecting rods P and Q by beingjoined to them as shown on Fig. 7 and as explained hereinafter.

The uprights g are of course slotted out as shown in Fig. 3, so as to allowof the passing of the pieces n, n, 0 and 0 and the cross heads N and O are kept in position by means of the pieces a n and 71 and the ones 0 0 and 0 To permit of the frame G and accessories turning around the column H, I join the connecting rods P and Q to rings and (1, having four equally spaced projections, as shown at p in Fig. 8 which extend out of the column H through the slots 71. into the rectangular annular spaces a or o of the collars n and 0 so that when the latter are forced up or down they also actuate the connecting rods P and Q which are joined to these ringsp and q as shown, and as "the projections 10 are not secured in any way to the collars n and o the latter are free to turn around the column H.

The connecting rods P and Q are joined at their lower extremity to the triangular levers S and T joined to the frame J, at 1,9" and j and to which are joined the two connecting rods V and IV which are also joined to the cranks c and w of the shaft U, which serves to run any suitable machinery. Of course, one of the connectingrods P or Q,-can bejoined to a pump at the same time, or both can be joined to the same pump by disconnecting one of the connecting rods V or W, and clampin g the two collars n and 0 together, so as to make them work in unison or again, I can make my windmill with only one cross head, that is singly without changing the principle of my mechanism.

My vane I is secured to the rectangular frame G by means of the piecesvl and t", joined respectively to the pieces g and g and is provided with the deflector i which is secured to it as shown, and serves to take a certain portion of the weight of the machine off the column H, and also to stop the mill automatically, if a sudden gale should strike it, for then it would rise and take the position i shown in dotted lines in Fig. 1, and in doing so, would pull on the cord 1' which is joined to the piece g at i, (that is eccentrically with reference to the center of rotation 2' and consequently would swing the vane I around in the same plane as the wheels K and L. At the same time the upper piece 't' would force the two uprights 9 together, by pulling on the lever i Whichin turn would act on the one 11 to which is joined the two pieces 1 and 1 (Fig. 9), secured to the pieces 9 and thus approach them together, this having for effect to press the two hubs 7t and Z together, and thus prevent any movement whatever of the wheels K and L, on the Wind falling, and the piece 2' retaking its normal position, the counterweight i will pull back the vane I in the position shown on the drawings through the cord 2' and automatically head the wheels K and L for the wind.

To stop the mill when required to do so, it is only necessary to pull on the cord i which passes up through the pieces g and g and around the segment 1 which terminates the lever 2' fulcrumed at 71 and joined to the lever 11 which is also secured to the piece t (Fig. 4), this having for effect to swing around the vane I in the same plane as the wheels K and L and pressing the two hubs k and Z together as already explained, the releasing of the cord of course lets the weight 2', pull back automatically the vanein its normal po-=- sition, as already explained.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a wind mill the combination of the two wheels K and L secured to hubs k and l, turning with and on shaft M and having the disk cranks k and Z joined to the connecting rods and 1*, cross heads N and 0 having the pieces n, n, 0 and 0' joined to the collars n and 0 rings 19 and q having projections 12 and secured to connecting rods P and Q, levers T and S connecting rods V and W and shaft U, with the rectangular frame G, hollow column H having the four vertical slots h, frame J and vane I substantially as described and for the purposes set forth.

2. In a wind mill the combination of the mechanism of the wind mill with a stopping device composed of a vane I supported by the pieces 1' and t" and having the deflector 2' automatically locking the mill through the cord t levers 2" and i pieces t and the uprights g substantially as described and for the purposes set forth.

3. In a wind mill the combination of the mechanism of the wind mill with a hand stopping device composed of the cord 2' sector 11, levers 2' and 11 pieces 1 and 2' vane I levers t and 11 pieces i and 2' and the uprights g substantially as described and for the purposes set forth.

4. In a wind mill the combination of a hand and an automatic stopping device with an automatic starting one composed of the weight 2' cord 2' piece '5' vane I piece t' lovers 1' and 71 pieces 2' and i and the uprights g substantially as described and for the purposes set forth. 1 t

In testimony whereof Iaffix my signature in presence of two witnesses.

JOHN BOISOLAIR.
