ELEAZ'AR THOMAS PERDUE, OF HUGUENOT, VIRGINIA.

SOLAR-HEATING AUTOMATIC WELL-VENTILATOR.

SPECIFICATION forming part of Letters Patent NO. 627,010, dated J une 13, 1899.Y

Application led December 29,1897. Serial No. 664,299. (No model.)

To @ZZ whom, t may concern:

Beit known that I, ELEAZAR THOMAS PER- DUE, a citizen of the United States, residing at I-Iuguenot, in the county of Powhatan and State of Virginia, have invented an improvenient in Ventilating Vells, of which the following is a specication.

My invention relates to improvements in apparatus for Ventilating wells, all of which will be fully described hereinafter, and particularly pointed out in the claims.

The object of my invention is to supply freshv air to a well by means of a pipe having one end extending above the well and exposed to the heat of the sun and the opposite open lower end stopping at a point above the waterline, whereby the outer projecting end of the pipe becomes heated,causing a rising of the air through the pipe and a consequent vacuum in the well, which is supplied with freshair from above.

In the accompanying drawings, Figure 1 represents a well showing oneform ol' myinvention applied thereto. Fig. 2 is another sectional view of a well, showing a modified forni of myiiI vention applied thereto. Fig. 3 is aseotional View of a well, showing my device still further modified. Fig. 4. is a detached View of the lower end of the pipe within the well. Fig. 5 is a detached view of the hook for supl porting the pipe. Fig. G is a detachedview of the perforated cap at the outer end of the Referring now to the drawings, in Figs. l, 2, and 3 I show the dotted lines land 2, indicating low and high water, and the lower end,

of the pipe should extend to a point above the water-line.

3 is a pipe which extends down within the well and has its lower end at a point above* per outer end of this pipe is turned upward, as-shown at 5, and provided with a perforated cap 6 topprevent the admission of foreign matter into the pipe, while at the same time allowing a free outward passage of the heated air from within the pipe.

Situated near the upper end of the well is a Vertical standard 7 provided with a vertical series of perforations to receive a hook 5 for holding the horizontal portion of the pipe 4, .and by means of which the pipe can be raised or lowered in the well to suit the height of the water.

It will be readily understood that that portion of the pipe which is exposed to the suns rays will become heated and the air within the pipe consequently heated, causing an upward draft or current of air through the pipe, thus establishing to a certain degree a vacuum in the well above, but adjacent the wa ter-line, which is supplied with freshair, and this keeps the watersweet and healthy. It

will also be readily understood that the larger amount of pipe exposed, like that illustrated in Fig. 3, will cause a greater amount of air to be withdrawn from the well than where a small amount of pipe is exposed to the rays ot the sun, as illustrated in Fig. l.

Having thus described my invention, what I claim, 'and desire to secure by Letters Patent, is*

l. An improved Ventilating device for wells comprising a vertically-adjustable pipe eX- tending down within the well and having open lower and upper ends, and a support for ELEAZAR THOMAS PERDITE.
