EMIL R. BITTNER, 0F VICTORIA, TEXAS.

INTERMITTENT-OPERATING MECHANXSM.

To all fui/tom t may concern:

Be it known that I, EMIL R. BITTNER, a citizen of the United States, residing at Victoria, R. i?. D. #3, B0X 2S, in the county of Victoria and State of Texas, have invented certain new and useful improvements in intermittent-@pending Mechanism, of which the following is specification.

The invention has for an object to edect an improvement in automatic regulating meansrfor wind mills, applicable to use in assuring a supply of water in a tank at a mean level without liability of too frequent operation of the control. aim'is to give an improved and simple construction of ratchet and pawl and means for holding the pawls operative at one time and inoperative at another time.

lt is alsosought to give such a device as will not be easily deranged, which will not wear out quickly, and which may be produced at a low cost. Another purpose is to present an embodiment of the invention which will be applicable to use with any usual construction of windmill already in use, without modication of the original structure.

Additional objects, advantages, and features of invention will appear from the construction, arrangement, and combination of parts hereinafter set forth and shown in the drawings, where Figure l is an elevation of a windmill pumping plant having the present embodiment of my invention installed thereon.

.Fig 2 is a detail of the mounting of the .vaney and its control.

Fig. 3 is a plan view of the control.

o Fig. t is a detail of connections between the spider andl float.

rilhere is illustrated a tower 10 having a tank l1 of usual form thereon, supplied by any suitable pump, not shown,l operated by means of the pump rod l2 connected in a familiar way with the wind-Wheel 13. The wheel 13 isheld in operative or inoperative position by means of the vane le including the frame l5 pivoted on the rotating frame 16 `by which the wheel 13 and the drive connections therewith are carried. The vane is held yieldably in operative position by means of the spring 17, yand is drawn to inoperative position by means of the cable 18 extending around. suitable pulleys 19 and thence downward ythrough the tower to a point ofjcontrol. These details are well Specification of Letters Patent.

known in the art and do not comprise a novel part of my invention.

The point of control in the present case is a platform Q0, located on the tower over the tank ll and having suitably mounted thereon a bracket 2l upon which there is revolubly mounted a ratchet wheel 22 by means of a stub shaft 23. The outer end of this shaft also supports pivotally a spider 24, having two wiper arms 25 and 26 carrying small rollers 27 at their outer ends adjacent the 'perimeter of the wheel 22. The spider also includes the weight carrying arm 2S, upon which there is longitudinally adjustable a weight 29 consisting of a suitable'body of metal centrally bored and receiving the arm 28 slidably therethrough, a set screw being provided to secure the weight in adjusted position. rlhe shaft 23 is extended through the bracket 2l to a second smaller' bracket 3l, spaced from the first bracket, a drum 32 being carried upon the shaft between the brackets. Pivoted upon these brackets there is a yoke member 33, having a lever arm 34 extended therefrom and pivotally connected to the pump rod as at 35. p

The yoke has pivoted thereon a pawl 36, hanging so as to engage the ratchet under reciprocation of the pump rod, a weighted extension 37 being projected therefrom to bear the pawl against the ratchet wheel.

|The pawl is provided at the side toward the spider with a lateral flange 38, extending divergently outward and upward from the arc of movement of the outer end of the arm 26 which is adjacent thereto, the flange being also alined with the plane of oscillation of the arm. The yoke is so pivoted and the pawl 36 so located thereon that reciprocation of the pump rod will operate the ratchet wheel and rotate the drum 32.

In the inoperative position of the control-that is to say, the position in which the windmill is left free to operate the pumpthe weighted arm 28 is approximately or nearly vertical, resting against a checked lug 39 on the bracket 2l, while the arm 26 lies with the wiper 27 thereon engaged with the flange 38 of the pawl 36 so as to hold the pawl in disengaged position, permitting the pump rod to reciprocate without operating the ratchet wheel. The arm 25 at this time is approximately horizontal, the wiper thereon being engaged with a iiange 38 formed on a ratchet 40 having an inward` weighted extension 4l by which its upper part isborne inwardly toward the ratchet wheel. The arm inthis position holds the pawl il() disengaged also, the flange 38 being downwardly divergent from .the arc ot' movement' of the wiper 2 on' this arm. The spider is movable from this position in the direction of divergence of the pawl iianges to permit them to tall inwardly and engage the ratchet. Connected to the arm Q5 there is a link i2 extending (lov\n\,.'aitlly and connected to' a rocking arm e8 normally horizontal, p'ivoted intermediately of' its length on the tower trame, 4 To the opposite end of the arm 43 a second lower link i4 is connecte ed, entend'ing into the tank ll, where a. iioat l5' is engaged slidably thereon, the movement of which on the link is limited npper` andl'ower stops Li6 secured` to the link.

, lt will be seen that when the level oit the water in the tank' falls to a sufficiently low point'the float will engage the lower check, and when it rises a cert-ain height the upper checkwill be engaged by the float. The last mentioned action will result in the link 4t2 pulling' the spider'V toward disengaged position, and after the weight 29 has moved a Y certain distanceV it will fall rapidly moving the spider to entirely disengaged position, andholding it there until the weight engages the lower check whenthe spider will be returned to engaged position, lifting the pawls from engagement with the ratchet rss wheel, Y v

Connected to the drum 32 there is a cable 18, before mentioned, so that when the lower check is engaged and the ratchet and pawls held disengaged the vane 1s 'tree to move C .9 under action of the spring l? to operative c position, the wheel l2 then being held so as to be rotated by any wind ot snicientforce and operating the pump to lill the tank. lWhen the upper check e6 isl engaged and the ratchet and pawl allowed' to engage the ratchethwheel, the reciprocations of the pump ro'dwill canse rotation ot the ratchet wheel and drum through the agency ot the yoke 33 and pawl 36, winding the cable 1S so as to draw the vane le to inoperative position. Any tendency of the wheel 13 then to operate will be checked by the engagement of the pawl 3 with the ratchet, by reason oi the connection of the pump rod thereto and the tautening of the cable i8.

Y The form of the connections between the lioat andspider maybe varied to suit variousy conditions and types of construction with which it be employed, andthe control device may be mounted in other" situations thanthat shown, as, for instance, it may be mounted on the top of the tank' ll, and theV lower link connected to thearm 26 of the spider, orr connections made between thespider anda neat in a tank at a disiicve IH lie Bowler bym/LS' Suit/ able links and bell cranks, these details being sn'iiiciently obvious not to require illustration.

lt is desirable that the connection between the links and the arm Q5 be made with a lost motion connection, in order that as soon as the spider has been moved a little way it may fall immediately into position to allow operation of the drum, under action oi the weight 29. ills shown, this connectionA comprises rotating pin et? having. an apertured head through which the upper end of the link e2 is sli'dably engaged The link is provided with collars 4:9 suitably spaced thereon to' permit the Yaction described, By' this arrangement the float link 44 will not require a great degree of movement in order to set the controlling mechanism pinto' operation to stopthe mill, and it will'be possible to allow the tank toV lillto a high point without liability of running overa lit the controlling device is located at a considerable distance from the tank, VwhichV be found desirable to make connections with the arm 2 8, instead of the one 25, as dotted in Fig. 2. A Y

ln Fig. e there is shown a preferable cone struction of the connections between the spider and link e2, which consists in Vforniing a longitudinally extending lug 5G on the arm 25, in which there is formed'Y an oblongv slotl 5l, throughwhich the link is engaged. The check collars'eQ are engaged upon the link above and below the lugs, as with the rotating pin previously described. Similar lugs 52 one of whichl is shown may be :termed on the arms 26 and Q8, to be used in case found desirable in making connec`- tions with a slope point.
