STROKE-REGULATOR FOR WINDMILLS.
To all whom 2'2, may concern:
Be it known that I, ALFRED B. SAB IN, a
citizen ofthe United States, residing in the any other device actuated by a reciprocating movement. While the invention may be used in connection with different kinds of machinery, it is described in the following specification as applied to a wind mill. The general object of the invention is to provide a very simple and compact regulator which will operate automatically to adjust the crank arm to which the connecting rod is attached that operates the pump. A special object of the invention has been to produce aconstruction in which the crank pin will be securely held in any of its adjusted positions and without the presence of any lost motion; and also to construct the device in such a way that the adjusting mechanism is a locked mechanism as regards thecrank pin, so that the crank pin can exert its force on the connecting rod 'without'being moved in the slightest degree from its path of movement by the forces developed in the connecting rod; also to construct the crankarm in a simple manner which will facilitate the mounting of the parts of the'mechanism within it. l I I Further objects of the inventlon Wlll ap- 7 pear hereinafter.
Thev invention consists in the novel features, and inthe, general combination of parts to be particularly described hereinafter, all of which contribute to produce simple and efficient stroke-regulator for windmills. A'preferred embodiment of my invention will be described in the following specification, while the broad scope of my invention will be pointed out in the appended claims.
In the drawing, Figure 1 1s a rear elevation of a windmill mechanism showing the central portion of the wind wheel, certain parts of the mecha nism being broken away; V V
Fig. .2 is a vertical cross section through the arm atthe middle point; the view shows'the hub of the auxiliary wind wheel in Section;

Fig. 3 is plan of the arm with the outer sectionor cover of the arm removed;
Fig. 4 1s a cross section through the hub of the auxiliary wheeland illustrating the manner in which a spring ismounted there- 1n; and I Fig. 5 is a section taken on the line 55 of Fig. 3 but showingthe bolt in place instead of removed as in Fig. 3. i
Referring more particularly to the parts;
1. represents the shaft ofthe main wind' wheel,the central portion of which is indicated by the dotted lines at 2. This shaft 1 1S rotatably mounted in asuitable bearing 3 which has a downward extensioriA: which may be mounted to swivel in a bearing in any suitable manner toenable the wind wheel 2 to be held in a plane substantially at rlght angles to the direction of the wind. One'end of the shaft l carries a circular head 5 to which there 'isattached a crank arm 6 and thiscrank arm is preferably constructed of two sectionsfi. and 6 which are clamped together' and secured to the head 5 short throughbolts 8, (seeFigs. 1 and 5).
On this arm'6 there is guided 'a crank pin 9 with which there is associated threaded adthe end of the shaft 1. The auxiliary wheel 11 is preferably formed with a hollow hub 12 which is connectedto the shaft l'b'y means ofa spiral sprin'g 1 3; [It should be understood that the auxiliary wheel is in front of the'mainwindwheelso that the wind comes 'by long through bolts? (see Fig. 2) and i against it in thedirection of the arrowsim dicatedin Fig. 2.. The effect of the wind is to rotate the auxiliary wind wheel in the same direction as the mainwind wheel. 3 The spring-'13 is'm'ounted in such a way that if an acceleration ofrotation of the'auxiliary wheel takes place, the tension in the spring 13 will beincreased; in other words, if the wind becomes stronger there will be'a relative angularadvance of the auxiliary wheel 11 with respect to the mainwind. wheel.
This relative movement is utilized by means of an inner shaft 14: which isrig idly; secured [to the hub 12 and which lies within the main shaft 1 which is made of tubular form." Any suitable means is provided for connecting the inner shaft 1% with the adjusting means 10 to utilize this relative movement, the operation being such that when the wind velocity increases the adjusting means 10 will be actuated in amanner to move the crank pin 9 further away from the shaft 1. This will increase the stroke of the pump, the plunger of which is actuated by a connecting rod 15 attached to the crank pin, (see Fig. 1).
In order to accomplish these effects I prevfor to construct the twosections 6 and 6" cross head 17. In the present instance these worm wheels are constructed so that theyv operate as nuts on the threads of the two feed screws or ad usting screws 20. For
convenience the hubs of these worm wheels.
are mounted in suitable ballbearing collars 21 whlch are received 111 sockets 22 formed in the adjacent faces of the two arm sec-:
tions 6 and 6}, and the sides of these collars 21 may be provided w th dowel screws 2% which assist in securing the collars in place.
In order to provide clearance for the connecting rod 15,the outer ends of the bolts 7 are countersunk into the wall of the casing. The special bolts 8 are also countersunk into the wall of the arm sectionfi in order to prevent their interfering withthe free movement of the cross heads 17 and 25...
