- DEVICE FOR CLEANING OUT WELLS.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed February 4, 1905. Serial No. 244,185.

To all whom it may concern.-

Be it known that we, GEORGE W. OSBORN and JOHN H. YOUNG, citizens of the United rocks, boards, cups, clippers, spoons, or other small articles and dirt or sediment which may be dropped into or accumulate in a well.

It also has for its further object to provide a device which is simple, inexpensive, and very durable in construction and exceedingly easy and effective in operation.

Our invention consists in the construction,

- combination, and arrangement of features, as

more fully hereinafter described and claimed. Referring tothe drawings, Figure 1 is a front elevation; Fig. 2, a top plan view, partly in section, on line a: as of Fig. 1; Fig. 3, a detail view of the lower end of one of the arms, and Fig. 4 a detail view of one of the scoops.

In the drawings, in which like numerals of reference denote like parts throughout the several views, 1 represents an arm provided at the top with a laterally-extending bracket 2, having a downwardly-extending lug 2-on its end. An arm 3 is pivoted to the arm 1 by means of lugs 4: and a pin 5. The movement of the arm 3 is arrested in its outward movement by its upper end abutting against the lug 2, thus preventing said upper end from being moved too far outward and the lower ends of the scoops from striking each other when said arm 3 is released. Both of said arms are curved laterally outward at points 6 and extend downwardly and terminate in tapering forks 7 at their lower ends, which have teeth 8 on their inner surfaces.

A strip of metal 9 is secured to each of the arms 1 and 3 by means of a bolt or screw at point 10, and said strip 9 is provided with a lateral offset at point 11.

A scoop or plate 12, provided with teeth 12,

is securely clamped between each of the forks 1 7 and the strips of metal 9 and securely held by means of screws 13 and the teeth 8 and 12, said scoops being provided with loops 14, which loosely embrace the outer tines 15 of the forks, and thus hold the scoops in place on said forks. Although the scoops are shown as provided with teeth for the purpose of engaging the teeth of the arms, said scoops may be made without the teeth, in which event the teeth on the arms-will bite into the surface of the scoops when clamped thereto. The function of the teeth 8 is to hold the scoops when adjusted and clamped at different points.

16 is a leaf-spring, one end secured to the top of arm 1 at the point 17 by screw-bolts 18 andslanting laterally downward from the point 19 and the opposite end contacting with the inner surface of the arm 3 above the pivotal point with the arm 1.

, On the top of the bracket 2 a U shaped casing 20 is secured by means of screws 21, said casing provided with a vertical trigger 22, pivoted in the inner end of the'casing by means of a pin 23, which is mounted in holes 24 in the sides of the casing. At the opposite end of the casing from the trigger a pulley-wheel 25 is mounted on a pin 26.

27 is a lever pivoted on a pin 28, one end provided with an eye and the opposite end provided with a. downwardly-extending lug 29, behind which the upper end of the trigger is held when the lower end is holding the arm 3 in its outward position. The lever 27 is operated to release the trigger by means of a cord or rope 30, which is secured to the eye of the lever 27, and then extends downward once around the pulley 25 and then upward.

31 is a loop secured to the top of the arm 1.

The device is lowered and raised into and out of a well by means of a rope or cable 32, attached to the loop 31. When it is desired to set the device to operate in a well of smaller dimensions, the pivot-pin of the lever 27 is shifted to the holes 32 and the pivot-pin of the trigger is shifted to the holes 33, which will limit the outward movement of the arms 1 and 3.

v A hand-lever 34 is provided for the pur' pose of setting the device before lowering it into a well, said lever being secured to the arm 1 by neans of a pin 33, which engages an elongated slot 36 in said lever 34.

35 is a hook projecting from the upper end of the lever 34, said hook being for the purpose of bringing the upper end of the arm 3 into position behind the trigger 22.

The operation is as follows: The pivoted arm is pushed in ward at the top until it passes beyond the trigger and bears against the rear edge of the same. Then the inner edge of the lever is pushed downward until the lug thereon engages with the top of the trigger, when the device is set and ready for use. The device is then lowered into the well by means of the rope 32 until the scoops at the lower ends of the arms embrace the article or other matter desired to be removed from the well. Then by pulling upward on the cord 30 the lever 27 will release the trigger, which in turn .will release the upper end of the pivoted arm, and the pressure of the spring 19 causes it to move outward, which causes the inner end carrying the scoop to move inward and grasp and clamp the article or-other matter in the well, and, finally, to pull the device out of the well and release the said article or other matter by returning the parts to their normal position by engaging the upper end of the pivoted arm behind the lower end of the trigger. I

We preferably make all the parts of steel; but'they may be made of any material found suitable forthe purpose.

We do not desire to be understood as limiting ourselves to the specific details of construction and arrangement as herein described and illustrated, as it IS manifest that variations and modifications may be made in the features of construction and arrangement on the adaptation of the deviceto various conditions of use without departing from the spirit and scope of our invention and improvements. We therefore reserve the right to all such variations and modifications as properly fall within the scope of our invention and the terms -of the following claims.
