PATENT FFlCEw TRACK-SANDER.

SPECIFICATION forming part of Letters Patent No. 745,065, dated. November 24, 1903.

Application filed June 10, 1903. Serial No. 160,795. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. M. KNIGHT, a citizen of the United States, residing at Huntington, in the county of Huntington, State of Indiana, have invented certain new and useful Improvements in Track-Sanders; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sanding devices for cars; and it has for its object to provide a pneumatically-operated means for feeding the sand from the sand-box to the rail, a further object of the invention being to provide aconstruction which may be adjusted to secure the best results under different specific.

conditions and in which the feedof the sand may he graduated.

An additional object of the invention is to provide a construction from which any obstructions may be removed readily and without disjointing the several parts of the appaent invention.

through the head or casing of the sander.

ratus.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in both of the views, Figure 1 is a side elevation showing a sanding apparatus embodying the pres Fig.1) is a vertical section Referring now to the drawings, the present sander comprises a sand-box 5, from which leadswhat may be termed a suction-pipe 6, which extends downwardly and through which sand from the sand-box is drawn for discharge to the track. Engaged with the lower end of the suction-pipe is a head or casing 7, having the vertical tubular branches 8 and 9, which aline, and the horizontallyalining

tubular branches

10 and 11, the suction-pipe having threaded engagement in the upper branch 8 of the casing. Within the branch 10 of the casing is screwed a bushing '12, and into the inner end of the bushing and lying within the casing and in axial alinenientrwith the

branches

10 and 11 of the easing is a nozzle 13, having a head 14 at its free end, which lies just short of the inner end of the branch 11 of the casing and with its face in close relation to the inner end of the bushing 14, which is screwed into the branch 11 of the casing. The outer end of the bushing 14 is threaded to receive the discharge-pipe or delivery-pipe 15, through which the sand from the casing is blown to the track to be sanded, said pipe extending outwardly or horizontally and then downwardly and rearwardly, so that it may lie with its discharge end close to the surface of the rail to be sanded and just in advance of a car-wheel.

The inner end of the bushing 14: is gradually increased in internal diameter from the point of engagement of the discharge-pipe to 55 the innerend of the bushing, so that the sand may flow unobstructedly from the casing to the bushing.

The lower branch 9 of the casing 7 is internally threaded to receive a plug 10, which is bushing 14, so that by suction in the pipe (3 and the casing '7, the sand is drawn from the sand-box into the casing and then blown out through the bushing 1% into the deliverypipe 15, through which it is forced and discharged onto the ,track.

the casing in great part by its own weight; but the suction established insures an oven feed of sand.

It will be under- 35 stood, of course, that the sand will fall into By the use-of the bushings described -and go the arrangement of the air-discharge nozzle the ditferentparts of the apparatus may be readily adjusted to obtain a greater or lesser discharge of sand, itbeing' understood theatr in practice modifications of the specific construction shown may be made and that any suitable materials and proportions maybe used for the various parts without departing from the spiritof the invention.

What is claimed is-- In a sanding apparatus, the combination with a casing having vertically-alining tubular branches and horizontally-alining tubular branches, of a sand-box having a suction-pipe depending therefrom and engaged in the upaway frem the inner edge of the said bushper vertical branch of the casing a bushing ing to vary the sand-supply,fand a plug re in one of the horizontal branches of the. movably engaged in the'lowe'r vertical branch easing, and an airsupply pipe connected of the casing? 4 I e, 5 with theepposite horizontal branch, a nozzle In testimony whereof I affix my'sign'abure I5 within the casing'connected adjustably'wibh in presence of two wibnesses.-
