Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed .T une 8, 1918. Serial No. 238,984.

To all whom t may concern Be it known that I, BnYN'rn BniNTnsoN. a'eitizen ot the United States, residing at debolt, in the county of Sac and State ot' Iowa, have invented certain new and use'ful Improvements in Pump-Gperating lvIechanism7 ot which the following is a speciiica tion.

The invention'relates to a pump operating mechanism. The object of the present invention is to improve the construction of pumpoperating mechanism and to provide a simple, practical and efficient pump operating mechanism of strong, durable and com paratively inexpensive construction adapted to reciprocate positively the vertical pump rods or stocks ot' a double acting pump.

VJ ith these and other objects in view the invention consists in the construction and novel combination and arrangement ot parts hereinaiitertnlly described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended, it being understood'that various changes in the torni, proportion, size and minor details of construction, within the scope Y oit the appended claims may be resorted to without departing 'from the spirit or sacrilicing any ot the advantages of the invention.

In the drawings:

Figure 1 is a front elevation of a pump operating mechanism constructed in accordance with this invention;

Fig. 2 is a transverse sectional viewof the same. Y

Fig. 3 is a detail view ot the Apump rod cushioning device.

Like numerals oil reference designato corresponding parts in the several ligures oit the drawin'.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, the pump operating mechanism comprises in its construction a pair ot'. vertical reciprocating` rods or stocks 1 and 2 having upper and lower racks which are adapted to mesh with upper and lower prnions .41- and 5 which are located at opposite sides of the pump rods and which are alternately carried into engagement with the same, the pinions at the right hand side ot the pump rod being adapted to mesh with the racks `for moving the pump rods m. a downward direction and the pinions at the left hand side of the pump rods being adapted to mesh with the coacting racks te impart an upward movement to the pump rods. The upper pinions it coact with and actuate one pump rod and the lower set ot' pinions 5 reciprocate the other pump rod. The pinions 11 and 5 are slidably mounted on and carried by upper and lower slidable supports 6 and which are mounted upon upper and lower portions 8 and 9 ot a main or supporting 'frame 10 which may be of any desired construction and which may be also provided with any suitable means for guiding the supporting members 6 and 'T in their sliding movement to gear the pinions alternately into engagement with the racks ot the pump rod.

The pinions are moved simultaneously to carry them into and out of meslrwith the said racks and with a master gear il, suitably mounted upon the main or supporting frame l0 Vby a shaft or axle 12 and meshing with a driving gear 13, which-may be operated from Vany suitable source ot power. Thefmaster gear is located between the'upper and lower'pinions -L and 5 and it simultaneously engages one of the pinions at the right hand side of the pump rods or stocks and one of the pinions at the left hand side ot the same to move the pump rods in opposite directions. IVhen the right hand pinion is in mesh with the rack of one pump rod the latter will be moved downwardly and when the left hand pinion is in mesh with the rack of the other pump rod the same will. be moved upwardly.

The upper .slidable support, which has a limited movement in each direction is locked against accidental movement by means o't dogs 15 and 16 to maintain therupper pinions alternately in mesh with the master gear and with the pump rod. The dog'15 which is pivoted or hinged at the outerV end as shownis adapted to drop into abutment with the adjacent end of the slidable support G when the latter is moved to the right, and it is urged downwardly by gravity and also by a spring 17 ot a trip or operating rod 1S having its upper end arranged to lift the pawlor dog 15 and .its lower end located in the path ot' eccentric-ally arranged projections 19 which are Vcarried by the master wheel 11. The operating rod 1S is arranged in suitable guides 2O of a. bracket or block 2l of the main or supporting trame 10 and.

the lower end or portion Q2 ot the operating or trip rod 1S 1s inclined 4tothe vertical and is adapted to'be engaged by the eccentrically arranged lugs or projections 19 whereby when one of the projections comes in contact with the offset portion of the rod 18, the latter will be lifted and will carry the pawl or dog upwardly out of abutment with tlief slidable support 6 and permit a coiled spring 23 to actuate the said support to carry the left hand pinion out of mesh and the right hand pinion into mesh. 'he spring 23 which is preferably of spiral form is interposed between a block 24 and an arm 25 which depends from the support 6'at'oiie end thereof. The spring 23Y tends to urge the suppoit 6 in one dii'ectioii and the sai-C support is automatically movable to the left and is actuated by the spring 23V when the pawl or dog 15 is tripped and lifted out of abutting relation with the said support 6 by the eccentric' projection 19.

The pawl or dog 16 automatically drops into abutment with lthe right hand end of the support 6 when the latter is moved to the left by the spring 23 and is adapted te be lifted out of such abutment by trip leverV 26 pivoted intermediate of its ends at 27 and having its upper arm arranged to lift the pawl or dog 16. The lower terminal portion 28 ofthe operating or trip `guides 37 of a block or bracket 38.

lever 26 is arranged at an inclination to the vertical and is located in the path of the eccentric projections 19 and is adapte'd to be engaged by the same and swing outwardly to disengage the right hand pawl or dog from the slidable support 6 to enable the said eccentric projection to engage the arm 25 of the said support 6 and move the latter to the right against the action of the spring 23. This will operate Yto move the right hand pinion out of engagement with the master pump i'od and carry the left hand pinion into engagement with the said parts.

The lower support 7 which is provided with an upwardly extending arm 29, is automatically -inoved to the right by a coiled spring 30 interposed between the said arm 29 Vand a block or piece 31 secured'to Vthe main or supporting frame 10 at the lower portion thereof. The lower support 7 is held at the limit of its left hand movement against the action of the spring 30 byvineans of a pawl or dog 32 pivoted intermediate of its ends at 33 upon a suitable block 34 and urged into engagement with the right hand end of the support 7 by a coiled spring 35. The coiled spring 35 is interposed between the outer portion of the pawl or dog and the main or supporting frame and it is adapted to be depressed by an operating or trip rod 36 arranged at an inclination tor-the vertical and mounted `in spaced The upper or inner'end of the operating or trip red 36 has an angularly disposedportion 39 inclined -to the vertical and located in wheel and the coacting the path of 'the eccentric projections '19 and adapted to be engaged by the same to move the rod 36 outwardly for disengaging the pawl Ipr dog 32 from the lower slidable support The left Yhand end of the slidable support is engaged by a pawl or dog V40 when the said support is at the limit of its right hand movement and the said pawl or dog40 when the said support is at the limit of 'its right hand movement and the said pawl or dog 40 is adapted to be lifted to release the support 7 by means of an approximately L shaped lever 41 fulcrumed at its angle at 42 and having the short arm arranged to lift the said pawl or dog 40. The other arm of the L shaped lever eXtends upwardly and inwardly at an inclination to the vertical and is arranged to be engaged by a trip or operating lever 43 fulcrumed at an intermediate point at 44 and arranged in substantially an upright position. The lower end of the lever 43 is arranged'to engage the L shaped lever and the upper end of the said lever 43 has an angularly disposed portion 45 inclined to the vertical and located in arranged projections 19. l Y

The eccentrically arranged projections 19 are located at substantially diametrically opposite points and they are adapted to engage 'the trip rods and the trip levers to operate the dogs or pawls and liavealso contacting with the inwardly extending arms 25 and 29 of the slidable supports and move the saine against: the action of the coiled springs 23 and 30. A reversal of the rack mechanism occurs at each quarter of a revolution Vof the master wheel, and a continuous reciprocation of the pumprods in opposite directions is effected. The mechanism is applicable to a single pump rod where only one set of employed. Each pump rod is provided at a point between theY operating mechanism and the pump with a break orjoint and is equipped with an air cushion 46 and a spring 47 to cushion and relieve the pump' cylinder 48 receiving a piston 49 mounted on the upper section of the pump rod and equipped with a suitable packing 50. The cylinder is provided at its upper end with a head or end wall 51 having a central opening through which lpasses the upper section of the pump rod rand the said spring 4T which is sleeved on the upper section of the pump rod and interposed between the cylinder end wall or head 51 and the suitf able stop 52 carried by the upper section of the pump iodrand arranged in spaced relation with the cylinder. The cylinder is provided with an upperv guide 53 and lower con- `pinioiis will be verging arms 54; receiving the upper and lower sections el the pump rod. The u'iiper guiding means e3 are preferably :in the erm ci a yoke and the lower arms 54C preferably consist of depending converging portions ot the cylinder and are suitably secured to the lower section of the pump rod.v The upper and lower sections of the pump rod are conrected by a chain 55 or other suitable flexible connection which permits limited independent movement of the sections to enable the cushioning Vdevice tol function.
