SAMUEL M. FULTON, OF POMONA, CALIFORNIA.
PUMPING-HEAD.
To all whom it may concern:
Be it known that I, SAMUEL M. FULTON, a citizen of the United, States, residing at Pomona, county of Los Angeles, State of California, have invented certain new and useful Improvements in Pumping-Heads, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to certain new and useful improvements upon my former Patent, U. S., No. 997,445, granted to me July 11, 1911, the object being to obtain a uniform up motion and a quick down motion in order to produce alap in the plungers so that the column of water will be continuous as the eccentrics pass the dead center whereby a non-pulsating pump is obtained.
Another object of the invention is to provide a double acting pump head which will operate with a minimum amount of friction and in which overhanging bearings are avoided and a direct central pull on all of the parts is obtained in order to dispose with any rubbing or twisting.
A further object of the invention is to provide novel means for producing a slow up motion and a quick return whereby the length of travel of the plungers can be readily adjusted.
A still further object of the invention is to provide a double acting pump head which is so constructed that thetload is taken slowly in order to prevent any jerking whereby all danger of injuring the mechanism is prevented.
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.
In the drawingsFigure 1 is a front elevation of my improved double acting pumping head showing the application of the same toa pump; Fig. 2 is a top plan view of Fig. 1; Fig. 3 is a vertical section taken on line 33 of Fig. 1; Fig. 4 is a side elevation, partly in section, of one of the walking beams and eccentrics showing the manner of adjusting the antifriction roller carried by the walking beam to produce the desired result; and Fig. 5 is a diagram showing the variable speed of the plungers in order to produce the lap so as to obtain a continuous column of Water. f
Like numerals of reference refer to like parts in the several figures of the drawiligs.
Specification of hetters Patent.
Application filed February 16, 1912.
Patented Jan. 14,1913.
Serial No. 677,956.
In the drawings, 1 indicates a foundation upon which is arranged a frame 2 provided with bearings 3 in which is revolubly mounted a drive shaft 1 having a pulley 5 over which is adapted to pass a driving belt, not shown, said shaft being adapted to be driven at a uniform rate of speed and the outer end thereof being mounted in a bearing 6 carried by a standard 7. The shaft 4 is provided with one or more pinions 8, but herein shown two in number, which mesh with drive gears 9 mounted upon a driven shaft 10 journaled in bearings 11 and on which are keyed eccentrics 12, 13 and 1 1, the two outside eccentrics 12 and 14 being keyed upon the shaft opposite to the eccentric 13 for the purpose later described.
Extending upwardly from the frame 2 are standards 15 provided with bearings 16 in which is mounted-a beam shaft 17 on which are mounted the walking beams 18, 19 and 20, said beams being provided with semicircular bearings 21 which fit over the shaft 17 and are secured in position thereon by cooperating bearings 22 as shown in Fig. 3.
Each of the beams carries an antifriction roller 23 mounted in a frame 24 which is adjustably mounted upon the'beam and as herein shown, each frame carries bolts 25 extending through slots 26 formed in the beams in order to allow the frames to be moved longitudinally thereon, said frames being locked in their adjusted position by nuts 27 While I have shown this particular manner of adjusting the antifriction rollers in respect to the eccentrics, it is, of course, understood that any other manner of mounting the same may be employed without departing from the spirit of my invention.
The outer end of the walking beam 18 is apertured in which is mounted a pin 28 carrying links 29 pivotally connected at 30 to the arm 31 of a guide sleeve 32 which is slidably mounted on a guide rod 33 arranged in suitable bearings 3435, at its opposite outside beams 19 and 20 are provided with bifurcated outer ends carrying pins 37 on\ which are mounted rods which have their cross-head 40 provided with a bearing sleeve 1 i lower ends pivotally. connected at 39 to a {x ll mounted upon the guide rod 33, said crosshead being connected to the outside pump rod 42 and as herein shown, the pumping head is arranged so that the central beam 13 driving the inside piston is moved upwardly while the two outside beams 12 and 1d are moving downwardly driving the outside piston, and vice versa.
in order to hold the antifriotion rollers into contact with the eccentrics at all times and to draw the beams downwardly after they have been forced upwardly by the sccentrics, provide each of the frames 24 with a flexible band 43 which surrounds the corresponding eccentric and is provided with antifriction rollers dd riding upon the face ofthe eccentric in order to reduce the friction as much as possible. The ends of the band 48 are pivotally connected to a rocking member 45 mounted upon the shaft carrying the roller 28. While I have shown and described this band carried by the member 45 of the frame 24 it is of course understood that the same can be carried by the beam by providing means for adjustably connecting the ends thereof to the beam so that the same can be shifted as the antifricroller frame is adjusted.
From the foregoing description, it will be seen that l have provided a pumping head in which friction is greatly reduced, antifriction rollers being provided for this purpose and by having the antifriction rollers adjustably mounted upon the beams in advance of the driven shaft, a quick down motion is obtained and a uniform tip-motion in order to obtain a lap of the plungers. if the antifrict-ion roller waspivoted directly over the driven shaft, the upward and down ward movement would be the same and as the main object of pump heads of this character is to obtain difierent movements of the strokes, it will be seen that it have provided novel means for obtaining this result. By
arranging the roller in advance of the driven suaft, 1 also produce a straight upward lift of the vvallnug beams by the eccentrics whereby a direct upward thrust is obtained and all side thrust avoided.
The operation of the invention is as follows: The driving shaft d being driven at a uniform rate of speed rotates the driven shaft it) through the medium of the gears and pinions d and 9 on which the eccentrics 12, 13 and 1d are mounted and it will be seen that the eccentrics 12 and 1d are tired opposite to the central eccentric 13 and rotate in unison so that the walking beams 18 and 20 will be simultaneously raised so as to lift the outside pump piston and at the same time the inside walking beam is being drawn down by the strap, the stroke of the pistons being regulated by adjusting the antifriction rollers in respect to the driven shaft. The movement of the pistons can be varied by adjusting the roller upon the beam and as in the diagram in Fig. 5, it requires a turn of seven-twelfths of the main shaft to raise the plungers and five-twelfths to let them down, giving a lap in the plunge-rs of one-twelfth of a revolution of the gear.
