'AUTOMA'IIC PUMP AND WINDMILL CONNECTION.

Be it known that I, THOMAS W. SLACK, a citizen of the United States of America, residing at Fort. Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Automatic Pump and Windmill Connections, of which the following is a specification.

My invention relates to automatic startersfor windmills andmore particularly to certain attachments which will automati-v callydetach a motor-operated pump jack from a sucker: rod and in quick sequence automatically connect the connecting rod'o-f a windmill to the sucker rod of the pump and in quick sequence automatically release the windmill for action; and the object is to provide simple devices for detaching a pump sucker rod from a gasolene motor in case the gasolene motor stops running and then in the same operation automatically attach a windmill connecting rod to thesucker rod; and in the same operation in quick sequence release the windmill so that the windmill will operate the pump; Other objects and advantages willbe fully explained in the following description and the invention will be more particularly pointed out in the claims.

to indicate the same parts throughout the several views.

The drawings show a portion 1 of a windmill tower for illustrating my invention. A gasolene motor 2 is shown. This motor 2 will not be described, as any gasolene motor may be used for the purpose. A pump cylinder 3 is. shown with a sucker rod 4. of ordinary type. A pair of pitman rods or arms 5 are pivotally connected to the motor driving gear of motor 2. The pitman rods 5 are pivotally connected to a yoke 6. The yoke 6 has a hinged member 7 and the two parts of the yoke are clamped on a bearing 8 which is made rigid with the sucker rod 1. This completes a description of the connection of the gasolene motor with the sucker rod for operating the pump with the gasolene motor. Means are provided for automatically detaching the gasolene motor from the pump sucker rod if the gasolene motor stops running. The hinged member is de tachably connected to the member 6. The hinged member 7 has a lug 9 which projects horizontally in a slot'in the member 6 and a pin 10 is projected down through the member 6 and through the lug9 to lock the lug 9 in the slot in the member 6. The lug orpin 10 is operated b Y a lever 11 which is fulcrumed on the m em er 6 and connected to the pin 10. The lever 11 is operated 1 the members 6 and7 together.

A vertical pipe or cylinder 12 is located at a convenient place about the pump. A weight 13 is vertically movable-in-thev cylinder 12. A cord 14 is attached to the weight 13 and run over an idler 15 stationed on theupper part of the cylinder and then extended to a drum 16 positioned near the bottom of the cylinder 12. tion of the pump by the gasolene motor the weight is supported in the upper part of the cylinder by a spring-controlled stop 17-. Means are provided for automatically drawing the stop 17 from under the weight 13. Water is discharged from the pump through a pipe 18 which discharges water into'a bucket 19. The bucket 19 is suspended over a tank 20 by a lever 21 which may be fulcrumed on the pipe 18; A weight 22 is adjusted on the other end of the lever 21 which will balance the weight of the bucket of water. A cord 23 is attached to the lever 211and run over an idler 2 1 and attached to the spring 25. Ordinarily the water will manuallv to set the pin 10 in place to lock During operathe sucker rod 4. v.

fall in the bucket and overflow into 7 the tank 20. The bucket is constructed with an opening in or near the bottom sothat water will continually run through the bucket and will gradually run out ofthe bucket 'ivlien the pumpstops. When the water runs out of the b'uck'et','the weight 22 willact on the" lever 21 and pull on the cord 23 and cause the cord to pull the stop 17 from under the weight [13. The. weight 13 will descend more or less slowly on accounthof the retarding effect, of the. cord .14 runningOver the idler 15 and being wound on the drum 16. A Weight 26 is. supported on a trip, 27 which is pivotally mounted on the cylinder 12. and 'projectsthrough a slot into thecylinder A cord 28 is attached to the weight 26 and run over anidler 29 and connected to the lever 11. As the weight 13 descends, it Will actuate the, trip 27 to. release the weight 26. The weight 26 will actuate the lever 11 to draw the pin. 10 out of thelug 9 and thusrelease the hinged member 7. of the yoke from the bearing Soon the sucker rod. A spring 30 will throw the member 7 .to the I dotted outline position shown in Fig. 7. Atfthesame time a Weight. 31 attached to the member 6 of the yoke by a cord 32 .will .move.,..the yoke member 6 slightly away from the bearing 8 These operationsdetacli the gasolene motor from Means are also provided for automatically connecting. the sucker rod 4, after it is released from the gasol ene motor, to the windmill connecting rod. 33. A casingor sleeve 34 is attached to the arms 35 which depend from the connecting rod .33. The suckerrod 4 moves fr'eelythrough the sleeve :34 during theoperation by the gasol enemotor. Means arezpr'ovided for automatically connecting the sleeve 34.to the sucker rod 4. Dogs 36 areipiv'otally mounted on 'the sleeve'34 and provided with shoulders 37 which are adapted to engage shoulders38 inthe suckerrod 4.; Theidogs .36 have slots 39. and locks 40 are attached tofa pivoted bar 41 forholding the vdogs 36 out of engagement withthe sucker rod 4. The locks 40 are held in'the slots 39 by a trip "42 which engages astop 43. on-the sleeve 34. A spring 44'attached tothe bar 41.zpresses-the-trip. 42 against the sleeve 34.. A- spring 45 attachedtotheslee've 341 and tothe barl41 normally holds thelocks 40 in the 'slots 39 and thus holdsthe dogs 36 out of engagement .with' the sucker rod.

' Weight 46.is..,suspended on the cylinder 12 by a trip .50 whichis pivotally mounted on thecylinder Y12 .and' projects Within the cylinder. A cord 47 isconnected to the weight 46 and run.over-idlers.:48 and 49 and connected to the tripi42'. As the weight 13 descends in the cylinder 12,-after the operation ofildetaching the "gasolene .IIlOllOIYfI'OIIl the sucker rod 4, it will'actuate the trip 50 to release the wa e 4.6. The wag-a 46 win actuate the trip 42 to release the bar 41. The spring '45 "w'i-ll"'draw the locks 40 out of the dogs 36 and springs 51 will thrust the dogs 36 into the notclfes38 in the sucker rod 4 and hold the dogs in these notches and thus lock the windmill connection tothe sucker rod .4. The Windmill is held out of gear by the ordinary rod or cable 52 and a locking lever 53 is attachedtothe cable 52, as inordinary operation. The lever 53'may be held by aspring clamp 54. A bellcrank lever 55 is fulcrumedon an extension of the base of the cylinder. 12 and one end projects into the cylinder and the other end-projects out of theccylinder. A cord 56 is connected tothe lever 55 andto a trip57 .whichwill throw the lever 53 out of the clamp 54 and release lever 53. .When the weight13drops down on the lever 55', the windmill will be thrown in gear so that the windmill :commences to runas soon asthe wind begins to blow.

It. will/be noticed that all the operations aretobe started by thedescent of the weight It is apparent that this weight may be permitted to dropcby various other means andthat variouschanges in the sizes, pro; portions, arrangement, and constru'ction of theyarious parts maybe made withoutdecy inder, a tripping means mounted on said cylinderand operatively connected with said motor connectingmeans, adapted to be: ac: tuated by Jsaidweight fo iautomati al y. disconnecting themotor connecting-,meansfrom 7 said sucker frod, and a gravity actuating means for automatically. releasing said trip-v ping means j: .;si 1 1 "2.- In? a pump provided withealternative driving means consisting of La -motor and fa windmill, means .connect1ng, ;s'aid3 pump to t the motor for operation ofithe pump, and means for maintaining the: 'ioperative connection ofthepump and themotor and for automatically disconnecting; the'motor' from the .pump. in. .eaSethe -watervstops flowing necting'the windmillitothe pump;
