SANDING DEVICE FOR LOCO MOT IVES.
SPECIFICATION forming part of Letters Patent No. 272,414, dated February 20, 1883.
Application filed January 4, 1883. (No model.)
keeping the sand-pipes of locomotive-engines in a dry condition, so that clogging from the v accumulation of moisture is eti'ectually prevented; and its novelty consists in causing an air-current from the atmosphere to flow con stantly through the pipes either in one direction or the other.
It consists, also, in the combination, with the sand-pipe ot'ordinary construction, ot'an opening at or near the source of sand-supply, communieatiug 'with the atmosphere, as will be fully described hereinafter.
In the drawings, Figure 1 represents a partial side view of a locomotive having my invention applied thereto, and Fig. 2 an enlarged sectional view of the upper end of the sandpipe and the adjacent parts. To enable others skilled in the art to under'-' stand my method and to carry it practically into efiect, I will proceed to describe the same fully, in connection with the proper apparatus for practicing the same.
A general statement of my method may be made as follows: An air-current from the atmosphere is caused to flow constantly throngh the sand-pipe, either by the motion of the engine or by the action of heat. The. following construction is employed to carry this method practically into effect:
A represents the sand-box, of the usual wellknown'or any other proper construction, which is located in any convenient positiouon top of the boiler, and provided upon each side with one or more delivery-pipes, a,'leading to points directly in front of the driving-wheels, in the manner well understood.
a represents an opening into the atmosphere through the side of the pipe, near its upper end, which is protected against the entrance of rain by a short bent pipe, at, as shown.
B Y represents a valve, of any suitable construction, in the sand-box, by means of which the delivery of sand to the pipes is controlled, in the manner well understood.
By means of the opening through the side of the pipe into the atmosphere an air current is caused to flow constantly through the same, whether the engine is at rest or in motion. When the engine is at rest the heat from the boiler warms the pipes sufficiently to cause a currentof air to pass through the pipes, the same entering at the lower opening and passing out of the upper. When the engine is in motion in a forward direction'the bent end of manner as 'to exhaust the air therefrom, and the current consequently flows in a downward direction. When the engine is in motion in a backward direction the bent end of the pipe take in the air, and the current consequently flows in an upward direction.
Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-'-.
1. The described method of keeping the sand-pipes of locomotive-engines in a dry condition, consisting essentially in causing an aircurrent from the atmosphere to'tlow constantly through them, substantially as described.
2. In combination with a sand-pipe of ordinary construction, an opening into the atmosphere at or near the source of sand-supply, substantially as described.
3. The pipea, with opening a and protecting-pipe a as described.
This specification signed and witnessed this 2d day-of January, 1883.

The operation is substantially as follows:
the pipe is drawn through the air in such.
is forced through the air in such manner as to.
