2 Sheets-Sheet l Feb. 14, 1939. M. HUNEFELD PUMP JACK Filed 001;. 29, 1957 2 Sheets-Sheet 2 Zuenbor MM Patented Feb. 14, 1939 UNITED STATES PATENT .OFFICE PUMP JACK Mark Hunefeld, Fort Dodge, Iowa Application October 29, 1937, Serial No. 171,740 1 Claim. (01. 74-55) The object of my invention is to provide an improved pump jack which may be easily and quickly attached to the ordinary pump such as is usually provided for operation by a windmill or other power device, wherein power from an electric motor or gasoline engine may be utilized to operate the pump in an efficient manner. I am well aware that various types of power actuated pump jacks have been manufactured for a similar purpose. These jacks, however, are usually somewhat frail and subject to becoming worn and. noisy in their operation, said jacks being usually insufliciently supported to provide a suitable and satisfactory working device.
A further object of my invention is to provide a pump jack adapted to be used in connection with a pump having a vertically supported pump rod, improved means for connecting the operative mechanism of the jack to the pump rod in such a manner that the said attaching means moves in a path substantially parallel to the movement of the pump rod, and in which is provided suitable guides wherein the pump rod is relieved of transverse strains.
A further object of my invention is to provide in a pump jack having vertically arranged guide members supported substantially parallel with the pump rod, and slidable means mounted therein for imparting movement to the pump rod, improved mechanism for imparting movement to said pump operating means.
My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated .are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:
Figure 1 illustrates a side elevation of my improved pump jack showing the manner in which it is applied to the pump.
Figure 2 is an end elevation of the same.
Figure 3 is a top view of my improved pump jack.
Figure 4 is an enlarged detail sectional view taken on the line 44 of Figure 2.
Referring to the accompanying drawings I have used the reference numeral If] to indicate the frame of my improved pump jack, said frame comprising spaced and parallel side members I I, said side members being connected at one end by means of a horizontal plate l2, the side members also being connected by a beam [3 located at points intermediate the ends of the frame so as to leave one end of the frame open for receiving the pump I 4. The side members are provided with lugs by means of which they may be fixed to a pump platform. The side members II are provided with upright tubular guide members I6, each of the said guide members l6 having its lower end fixed in brackets I! carried by the said side members. The outer side of each of the guides I6 is provided with slots [8 for receiving horizontally arranged pins l9, said pins 19 being fixed to the lower end of vertically arranged lift bars 20, said lift bars extending upwardly through the guides l6 and having their upper ends provided with a cross bar 2! comprising a pair of bars provided with laterally extending portions 22 and 23, the members 23 being secured to the upper end of the lift bars by means of bolts 24, while the members 22 are fixed to the pump rod 25 by means of a bolt 26. Each of the brackets I! is provided with a stub shaft 21 on which is rotatably mounted a cam 28 and also a gear 29, said cam and gear being fixed together to operate in unison. Each of the pins I9 is provided with a cam roller 30 adapted to rest and to travel on a. corresponding cam 28, so that as the cams 28 are rotated, the pins l9 will be elevated and lowered and carry with them the lift bars 20 and the bar'2l, thus providing means whereby the pump rod 25 may be elevated and lowered.
For rotating the gears 29 in unison I have provided in the side members I I a rotatably mounted shaft 3| having each end provided with a pinion gear 32 designed to mesh with a corresponding gear 29, the shaft 3| being supported in suitable bearings 33 carried by vertically arranged angle irons 34 secured to the side members ll.
Fixed to the center of the shaft 3| is a bevel gear 35 designed to mesh with a bevel pinion 36 carried by a drive shaft 31. The shaft 37 is rotatably mounted in boxings 38 carried by the plate l2. The outer end of the shaft 31 is provided with a pulley 39 for receiving a suitable belt by means of which the said shaft 31 may be rotated. Thus means is provided for simultaneously rotating the gears 29.
For anchoring the uprights l6 to the pumpstock 40 of the pump I4 I have provided clamp devices 4|, each of said clamps comprising a pair of strap irons bolted together by means of bolts 42 and provided with curved portions 43 for surrounding and clamping the pump-stock, and curved portions 44 for receiving the guide members I 6. Thus means is provided whereby the pump jack may be properly located relative to the pump with the guide members I6 and the pump-stock in the same vertical plane, so that the lifting force as applied to the lift rods 20 will be vertical and parallel with the rod 25, thus providing means whereby all lateral strains will be carried by the guide IBand thus relieve the pump cap 45 of any lateral wear on the lift rod 25.
One end of the frame 10 is left open so that the -said frame may be moved to position with the I pump between the side members of the frame and between the guides Hi, the frame being placed into position by simply moving it longitudinally without having to disassemble the pump jack frame or in any way interfere with the anchorage of the pump.
The cams 28 provide means whereby a most efiicient accelerated movement may be imparted to the pump rod 25, simply by so shaping the cams that the desired acceleration may be produced.
Thus it will be seen I have provided a pump jack of simple, durable and inexpensive construction which is rigid and may be firmly fixed to a pump so that the moving parts will operate in an efficient manner.
' I claim as my invention:
A pump jack, comprising a base designed to rest upon and be fixed to a well platform, said base having at one end spaced apart upright walls to receive a pump base portion between them, two upright guides fixed to said base in spaced apart relation to stand on opposite sides of a pump, means for rigidly supporting and accurately aligning said base and upright guides upon a pump comprising a pump clamp device fixed to the lower portions of the guides and shaped to surround and be fixed to a pump, and a second similar clamp device at the upperends of the guides, a guide rod slidingly mounted in each of said guides, means for securing their upper ends together and to a pump rod, two stub shafts fixed to the base and extended outwardly in opposite directions and being positioned substantially in line with the vertical axis of the pump, a cog wheel and a cam fixed together and rotatably mounted on each of said stub shafts, a roller carried by each of said guide rods and resting upon said cams, a shaft mounted on the base, and a pinion fixed on each end thereof, one being in mesh with each of said cog wheels.
