GRAVEIAPUMP FOR EXCAVATING WELLS, &c.

Specicaton of Letters Patent No. 883, dated August 15, 18738.

To all whom/alt may concern.'

Be it known that I, EBENEZER RICE, of

and three fourths of an inch in thickness represented by letter (A.) At abouttwentyone inches `from the bottom at (B.) it is reduced by bevel of two and one half inches to a neck (C.) of eight and one half inches in diameter and fteen inches in length,iin which `thepiston of the pump will operate when inuse. At its lower extremity it should have triangular spaces of about one inch (D) `to prevent it from becoming too iirmly fixed in the sand. A bottom of some strong wood not liable to split about two l inches in thickness with a circular opening in the center, of at least six inches, is firmly connected to the inside of theA pump by bolts, nails, or screws, immediately above the trangular openings. In the upper side of the bottom, are inserted in a secure manner, about twelve pieces of whale-,bone of. five and six inches, alternate in length, inclin ing to a point at top so as to form a cone, to prevent the escape of coarse gravel when received in the vacuum. This cone may be formed of slips of tough wood, plates of elastic metal, or any other substitute which will preserve a conical form, easily admitting the substance to be excavated and preventing its escape. Whale bone is found to answer the purpose perfectly, can easily be replaced when broken, is elastic, strong, and cheap. To prevent sand and fine gravel from escaping, a shirt or piece of canvas, of about the size of the inside of the pump, is nailed or otherwise attached to the bottom, immediately and closely around the insertion of the whale-bones. It is about twelve inches in length and open at the top, and collapsing around the cone prevents the passage of all substances from the bottom `of the pump except water.

The piston (E.) is in the usual `form of cast iron,` rmly attached to its prod, and having` from eight to twelve holes of an inch or less in diameter, to permit the escape of the water,-but should not be so largeV as topermit coarse gravel to pass, which, by becoming wedged between the outside `of the pump and the tubing, would obstruct the removal of the pump whenA charged or loaded with gravel. Encircling the rod is a thin cast` iron capor valve (F) with `leather.

play or slide upon the rod about three inches toa bulb or enlargement of the rod (G.) The upper extremity of the neck is` surrounded by a band (H.) attached by rivets, and bent so as to form holes'or eyes (I) for the attachment of the bail (J) whichencircling the rod at its curve, its extremities pass through the eyes, and for its more ready con# nection and detachment, are secured by the split, or double wedge elastic keys (7s).

Use: This pump, or machine, is inserted in awell, or shaft, which should be properly tubed, with cast or sheet iron or other ficien'tly charged with the substance to be removed, when it is raised by a windlass or other power. It is particularlyadapted to the excavating of shaft pan brine, and-was discovered While excavating` wells for that purpose, as no instrument was known, which would readily raise the gravel from the bed without great delay, and difficulty, and at same time leave the sides of the well loose, and pervious to the transmission of the brine; the ordinary process of drilling merely crowding the stones from the shaft, and rendering` the sides ofthe well compact, hard, and nearly excluding the passage of small streams of brineinto the Well. 1t can be made of any size corresponding with the tubing', or capacity of the shaft, but the above is recommended as a suitable size, which has been found by practice, to answer a valuable purpose.V It may also be used to eXcavate sand, or gravel, fromV docks, or rivers, and to raise articles from beneath deep water, when their location is known.

What we claim in behalf of EBENEZER RICE and the legal representatives of JAMES and the legal representativesv of JAMES J. J. RICE, deceased, and desire to secure by Letters Patent, is-

The manner in which we have combined and connected the respective parts of the above' described'machine, 'for the purpose yof excavating wells andV shafts, and the removal of sand andV gravel therefrom,V that is to say, weclaim the combinationof the exhausting apparatus with the cylinder, the conical bars of whale-bone,'or other material, and the canvas surrounding the same,

constructedrand operating in the manner set forth. Y Y Y .LAURA RICE,

' EBENEZER RICE. Witnesses:
