SAND-TRAP FOR ARTESIAN WELLS.

SPECIFICATION forming part of Letters Patent No. 485,064, dated October 25, 1892.

Application filed February 5, 1892. Serial No. 420,423- (Nomodel-l To all whom it may concern.-

Be it known that I, BENJAMIN F. SMITH, a citizen of the United States, and a resident of Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Sand-Traps for Artesian Wells,of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in sand-traps for Artesian or driven wells, and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a vertical section of the invention, showing the vacuum and suction pumps in elevation; and Fig. 2 represents a cross-section on the line X X, shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

The sand-trap consists of an inc-losing shell orchamber, preferably composed of a middle cylindrical shell A and closed top and bottom B O, which are secured air-tight to the re spective ends of the middle shell A, as shown in Fig. 1. From the shell A lead a number of pipes 01 to the Artesian or driven wells from which the water is pumped, each such pipe at being provided with a valve or cut-off D, which may be opened, closed,0r regulated by means of a suitable hand-wheel D, as shown in the drawings. Above the supply-pipes d d is located a pipe e,leading from the shell or chamber A to the pump E, by means of which the water is forced to the place where it is to be used. Between the pipe-openings d cl and e is located, within the shell or chamberA, a perforated wire screen or netting F, which is supported in any suitable or practical manner within said shell A, and it serves for the purpose of arresting sand, grit, and impurities that may pass from the wells through the pipes d 01 into the chamber A. In practice I leave an annular space f between the periphcry of the netting F and the interior wall of the shell or chamber A, so as to permit an unobstructed flow of Water from pipes 01 d to the pump E in case the meshes of said netting F should become clogged.

0 represents the sand or grittysubstances arrested in the lower part O of the sand-trap. The upper part B serves as an air-chamber, and it is connected by means of a pipe I) to a vacuum-pump B, by means of which the surplus accumulation of air may be pumped out from time to time, as maybe desired.

G is a glass gage connected to the shells A B above and below the desired normal level of the liquid in the said trap for the purpose of ascertaining from time to time the height of the liquid therein. By this arrangement a single sand-trap may be connected to any desired number of wells, and by shutting off or opening any one of the valves D the water may be pumped from one or more of the wells, as may be required.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- In a sand-trap for Artesian or driven wells, the combination of a closed shell A,having a series of radiating valved well-tubes d and p containing ascreen F, arranged to provide an annular water-passage f between the periphery of the screen and the internal surface of the shell, a pump E, having a pipe e connected with the shell at a point above the screen, and a vacuum-pump B, having a pipe I) connected with the air-chamber in the top por tion of the shell, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 21st day of January, A. D. 1892.

BENJAMIN F. SMITH. \Vitnesses:
