INVENTOR ATTORNEY F. R. OWENS NITNESS:
Patented Dec. i6, l'l,
PUMP JACK.
Application tiled October 19, 1923. Serial No. 669,603.
Be it known that l, FRANK R. Ownws,
a citizen of the United States, residing at Beaver Crossing, in the count-y of .Seward c and State of Nein-asian, have invented new and useful lmprovements in Pump Jacks,
of which the following is a specification.
rlhis invention relates to improvements in a transmitting device, the general object of l the invention being to change the movement of an endless traveling member into a re.-
ciprocatory motion so that a pump or the like can actuated from the rotary member. 15 rl'his invention is an improvement over that patented by me on @et 3, 1922, No. 1,431,028.
This invention also consists in certain other features of construction and in the combination and arrangement of the several partsj to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
ln describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev eral views, and in which Figure 1 is a longitudinal sectional view with parts in elevation.
Figure 2 is a section on line 2--2 of Figure 1.
Figure 5) is a section on line of Figure 2.
Figure -l is a section on line 1 -lof Figure 2.
Figures 5, 6 and 7 are views showing a modification.
ln these views, 1 indicates a casing which is provided with the bearings 2 for receiving the shaft 3, one end of which extends through the casing to receive a pulley. 4 by which the device can be actuated from any suitable source of power. A shaft 5 is journaled in the brackets G carried by the top of the casing and these shafts are provided with sprockets 7 over which pass the endless chains 8. A pair of diametrically arranged tubes 9 are located in the casing and these tubes form guides for a reciprocating plate 10 which has its ends forked7 as at 11, to engage the tubes. The plate is located between the chains and has its lower end recessed, as at 12, to receive the shaft 3 when the plate is in its lowest position. A bracket 13 is fastened to the plate for supporting a shaft 14- which passes through the plate and said shaft carries the hooks 15 which are adapted to be engaged by the lugs 1G on the 60 chains so that the plate will be moved with the chains when the lugs are engaging the hooks. The hooks are freed from the lugs at each end of the stroke of the plate by means of the trip rods 17 carried by the 65 plato and which are normally held in raised position by the springs 20. A bell crank lever is pivoted to each side of the plate and said bell crank lever is connected by a link 21 with one of the trip rods and a link 70 22 connects the other part of said bell crank lever with a projection 23 on the hook 15. The trip rods are engaged by the threaded members 24 in the ends of the casing. rlhese parts are so arranged that when the lugs engage the hooks the hooks will be held stationary by the links and bell cranks but as the plate nears the end of its stroke the trip rod will strike the member 24C so that said rod will be moved longitudinally against the action of its spring and cause the link 21 to move the bell crank beyond the dead center so as to cause the link 22 to permit movement of the hook 15 when the same is engaged by a lug and thus permit the lug to pass by the hook. When. this taking place the lugs on the other chain will come into engagement with the hook on the other side of the plate and thus cause the plate to move in an opposite direction. Thus the plate is given a reciprocatory movement by the lugs on the chains and I prefer to provide sufiicient lugs to cause the plate to make three upstrokes and three down strokes at one revolution of the chain. Rods 25 are fastened to the upper ends of the plate and these rods pass through the top of the cas-ing and are fastened to a cross bar 26. Rods 27 are fastened to the cross bar and these rods pass through the tubes 9 100 and through the lower end of the casing and are fastened to the cross bar 28 to which the plunger rod 29 of the pump is fastened, the cylinder of the pump being shown at 30. sprocket 31 is carried by a bracket 82 ar- 105 ranged on the top of the cylinder and a chain 33 passes over this sprocket. One end of this chain is fastened to the cross bar 26 and its other end is fastened to a rod 84 which has its lower end secured to a weight 35 which is arranged in a weight pit 36. This weight will help in the lifting movement of the pump plunger so that the power is equally divided on the up and down strokes and provides an even movement of the pump rod.
Where the device is to be run by a wind mill or the like I connect the shaft 5 by the gears 37 with a vertical shaft 38 which is connected by the gears 39 to a shaft 40 which is driven in the usual manner by the wind wheel. rIhe shaft 40 and the upper end of the shaft 38 are supported by the frame 4l which may be placed on the turn-table of the wind mill tower. These parts are shown in Figures o, 6 and 7 and said figures also show the brackets 6 as being provided with a threaded extension 42 which passes through the top of the cylinder, the threaded part being engaged by a nut 43, the flange 44 of which being engaged by the flange of a sleeve 45 which is threaded to engage the threaded boss 46 in the top of the cylinder. Lugs 47 are provided on the top for engaging the inner part of the bracket to hold the same against movement. This arrangement of parts permits the bracket to be adjusted vertically for tightening or loosening the endless chain.
The housing will be made oil tight so that the parts can be thoroughly lubricated by having them run in oil and the housing for the gears 39 would also be made oil tight.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
Vhat I claim is l. A device of the class described comprising a casing, a reciprocating member in the casing, an endless traveling member therein, hooks carried by the reciprocating member, projections on the endless member for engaging said hooks, means for holding the hooks against movement, trip means for releasing the hooks at the ends of the reciprocatory movement, a cross bar connected ,with the reciprocatory member, a weight connected with the cross bar, means for connecting the cross bar to a member to be actuated, such means consisting of guiding tubes in the casing with which parts of the reciprocatory member engage, rods passing through the tubesand connected with the cross bar and a second cross bar connected with the lower ends of the rods and adapted to be connected with the part to be actuated.
2. An apparatus of the class described comprising a casing, a plate slidably mounted therein, upper and lower shafts in the casing, a pair of endless traveling members carried by the shafts, hooks carried by the plate, projections on the endless traveling members for engaging the hooks, trip rods, links connecting the same with the hooks and holding the hooks against movement, means at the ends of the casing for engaging the trip bars to move the links to releasing position, a bracket for supporting the up-v per shaft and means for adjusting the same vertically..
3. An apparatus of the class described comprising a casing, a plate slidably mounted therein, upper and lower shafts arranged in the casing, endless chains carried by the shafts, hooks carried by the plate, projections on the endless chains for engaging the hooks, trip bars, links connecting the same with the hooks for preventing movement of the hooks, adjustable means at the ends of the casing for moving the trip bars to cause the links to release the hooks and means connected with the upper shaft for actuating the same.
In testimony whereof I affix my signature.
FRANK R. oWQENs.
