ADJUSTABLE FOOT-GEAR FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent N 0. 730,524, dated June 9, 1903.

Application filed June 24, 1902.

To all whom it may concern.- Be it known that I, JOHN DONALD DOWNIE, windmill expert, of the villageof Avonmore, in the county of Stormont,in the Province of Ontario, Canada, have invented certain new and usefullmprovements in Adjustable Foot- Gear for Windmills, of which the following is a specification.

My invent-ion relates to improvements in foot-gear for windmills; and the Object of the invention is to devise a foOt-gearfor this class of mill which may be located at any desired position On the barn-floor Or any suitable outhouse or supporting-frame and which will ac :5 oommodate itself to any position of machine or any one of several which it is desired to drive; and it consists, essentially, of a mast or standard, suitable bearings secured to the same, a vertical shaft journaled in such bearings, a swinging bracket swung on the vertical shaft, a horizontal shaft journaled therein and in a cup formed on a sleeve through which the vertical shaft extends, abevel-gear being provided on the horizontalshaft and'a bevel-gear on the vertical shaft, with which the former meshes, and aquad rant being provided whereby the position of the swinging bracket may be adjusted so as to hold the horizontal shaft in any position to which it may be swung, the parts being arranged and constructed in detail, as hereinafter more particularly explained.

Figure l is a perspective view of my improved fOot-gear. Fig. 2 is a detail showing the form of quadrant and of the bracket.

'In the drawings like letters of reference indicate corresponding parts in each figure.

A is the mast, and B and G are the upper and lower bearings, the lower bearing having 40 formed therewith a quadrant O,provided with a series of holes 0. The quadrant O is provided with gripping-lips 0', whereby it is held from vertical displacement on the mast. Both bearings 13 and G are secured to the mast by suitable bolts.

D is a swinging bracket,through bosses on the ends of which the vertical shaft E extends, such vertical shaft also necessarily extending through the bearings B and 0.

Serial No. 113,028. (No model.)

D is a sleeve which is attached to or forms 59 part of the bracket D and is provided witha cup-shaped bearing or recess d.

d is a lug attached to or forming part of the bracket'D and extending laterally from the same Over the quadrant O.

F is a bolt extending through a hole 0 in the quadrant C and through a hole in the lug 61 the bolt being securely held in position by a nut.

' Gr is a horizontal shaft which is journaled in the bearing (1 forming part of the bracket D, and in the cup-bearing cl.

H is a driving-pulley.

I is a bevel-pinion on the vertical or drive shaft, which meshes with the bevel-pinion J on the horizontal shaft.

It will now be seen that by removing the bolt the swinging bracket, and consequently the driving-pulley H, may be swung into any position necessary, this of course depending on the position in which the machine to be driven is placed and which is most convenient for such machine. The bolt F may then be in sorted and the nut placed thereon, and consequently the horizontal shaft G and the pulley H held in the proper position necessary for driving the machine to whichit is intended to apply the power.

What I claim as my invention isl. The combination with the Inastand bearings and the vertical shaft journaled therein, 'Of a bracket having arms pivoted directly to said verticalsh'aft, a horizontal shaft journaled in the intermediate portion of the bracket and driving connections between said vertical and horizontal shafts, substantially as described.

2. The combination with the mast and bearings and vertical shaft, of the swinging bracket, the horizontal shaft and bearings therefor on the swinging bracket and'a suitable drive from the vertical shaft to the horizontal shaft, a quadrant secured to the mast and means on the swinging bracket for engaging such quadrant at any desired point, so as to hold the horizontal shaft in any position to which it may be adjusted as and for the purpose specified.

3. The combination with the mast and the bearings and vertical shaft, of the swinging bracket swung on the vertical shaft and having the lower end provided with an upwardlyextending sleeve having a cup-shaped bearing extending laterally from same, the horizontal shaft journaled in the bearing on the outer end of the bracket and in the cupshaped bearing and means for holding the swinging bracket in any position to which it may be swung as and for the purpose specified.

4. The combination with the bearingssuitably supported and the vertical shaft suitably journaled therein and the quadrant provided JOHN DONALD DOWNIE.
