CORPORATION OF CALIFORNIA.
Specification of Letters Patent.
Patented Jan. 13, 1920.
Application filed March 10, 1918. Serial No. 281,738.
To all whom it may concern:
Be it known that we, Boana'r Lnn BURNS and Fans FREAMOND WINGER, citizens of the United States, residing at Taft, in the county of Kern and State of California, have invented certain new and useful Improvements in Sucker-Rod Attachments to Prevent Sanding Up of Well-Pumps, of which the following is a specification.
Our invention relates, in general, to oil and other well-pum s, and particularly to an attachment to t e sucker-rods, the obect of which is to automatically lift the pump plunger out of the workingarrel whenever sand enters the pump in en cient quantlty to prevent its operation.
By thus lifting the plunger when beginmng to sand u the loss of a working barrel and parting o the rods are revented.
Our invention consists in t e novel attachment which we shall now fully describe by reference to the accompanying drawings in which we illustrate the referred form of the demos, it being un erstood, however, that changes in form and structure may be made without departing from the spirit of our nvention as set forth in our claims.
Figure 1 is an elevation of our attachment.
Fig. 2 is an elevation at right angles to ig. 3 is a top plan enlarged of the operat1ve port1on of the attachment.
Elg. 4 is a vertical section partly in elevation enlarged of said operative portion.
1 is the body or stock of the attachment, which in practice is bestin the form of a pair of steel reins. The top of the stock is provided with a T-head 2, by which it is suspended from the walking-beam (not shown) or other source of reclprocative mo- .tionv usually employed in the operation of wellpumps.
At the lower end the stock is formed with a tubular foot 3 split in the plane of its axis and adapted to receive the ratchet bar 4 which'passes axially through it.
In the foot 3 are mounted the pawls or dogs 5, pivoted at 6 and controlled by a spring 7 acting through a collar 8 resting on the pawls. The relation of these pawls' to the ratchet-teeth of the bar4 is such as shown in Fig. 4 that the bar may move upward relatively to the foot 3, the teeth of the bar then slipping the pawls, but not downward, since 1n this direction the ratchet teeth and pawls positivelv engage, and the pawls themselves rest on the base flange 9 of the foot 3.
10 is a clamp which embraces the splitfoot 3, being secured to one half by the cap screws 11, and engaging the other half through a tightening screw 12.
By loosemng the clamp 10 thehalves of the foot 3 may se arate to allow the ratchetbar 4 to be move downward, for setting it when desired.
The lower end of the ratchet bar 4 is adapted for connection as indicated at 13 by means of any customary or suitable coupling with the sucker rod string extendingto the pump-plunger.
The operation of the device is as follows:
The attachment is suspended from the walking beam or other source of reciprocative motion, by means of the T-head 2 of the reins 1. The lower end of the ratchet bar 4 is made fast at 13 to the sucker-rods, and then the walking beam is set inmotion.
As long as the pump works normally the ratchet bar 4 is held against the pawls 5 by the weight of the rods, on both the up and down strokes, and does not change its position relatively to the foot 3 nor to the walking beam. But as soon as the pump begins to sand up, the sucker-rods vary their stroke being then supported and limited by the sand in the working barrel of the pump, with the result that on the down stroke, the rods and the ratchet bar 4 remain stationary, while the foot 8 of the reins 1 drops along the bar the length of the pump stroke, the %awls slipping the ratchet teeth of the bar.
ut at the end of the down stroke the pawls catch the bar lower down and upon the up stroke they lift it, together with the suckerrods, so that the pump plun'ger is raised out of the barrel. This condition continues until the plunger is clear of the sand.
We claim:
1. A sucker-rod attachment for the described purpose comprismg a stock adapted for suspension from a source of reclprocative motion, said stock having a tubular split foot; a pawl pivoted and housed within said footfa ratchet bar adapted for 0011116011011 with the sucker-rod, said bar being fitted bearing on the coils!" a ratchet-bar eds. ted 20 through said foot for relative linear move: for connection with the sucker-rod, sei bar ment therein, the ratchet teeth of said her being fitted through the foot of the stock positivel engaging the awl on the u ward for relative movement therein, the ratchet stroke 0 the stock and sihppin it in t e reteeth of said her positively e ging both verse direction; and a regulate le clamp empawls on the u ward stroke of t e stock and 25 bracing said foot, whereby the ratchet bar slippin them in the reverse direction, and may be adjusted therein. a regu atable clamp embracing said split 2.
