TRACK-SANDER SPOUT.

Application filed December 7, 1914. Serial No. 875,779.

To all whom it may concern Be it known that 1, WILLIAM C. HAEsE, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Track- Sander Spouts, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a spout for track sanders of electric railway cars or the like which will be flexible and extensible and capable of turning to permit its lower end to be held in a fixed position close to and in front of the car wheels while its upper end is attached to the car body in communication with the sand hopper.

Another object of the invention is to provide such a spout for track sanders which may be constructed of metal so as to be more durable and eflicient and consisting of articulating segments with each segment overlapping the edge of the next segment below, both inside and outside of the spout so as to shed the sand traveling through the interior of the spout and so as to shed water and snow on the outside of the spout.

Another object of the invention is to further protect the spout against freezing by providing self closing lips at its discharge end that will prevent the introduction of snow or the like.

With the above and other objects in View the invention consists in the track sander spout as herein claimed and all equivalents.

Referring to the accompanying drawing the figure constitutes a central sectional view of a track sander spout constructed in accordance with this invention.

In this drawing 10 represents the floor of the car body containing a sand box or hopper, not shown, with an opening 11 through the floor through which the sand is discharged, as by a blast of compressed air as usual. A funnelshaped plate 12 surrounds the opening 11, and between it and a flanged ring 13 is mounted a flanged tubular swivel section 14 capable of turning on its axis and having the tapering portion of the funnel entering the flaring upper end thereof so that sand passing through the opening 11 is guided by the funnel to the bore of the swivel section 14:. A flange 15 surrounds the lower end of the tubular Specification of Letters Patent.

Patented June 22, 1915.

swivel section 1 1 and is spaced therefrom to form an annular groove 16 within which at diametrically opposite points are pivot pins 17 pivotally connecting the upper edge of a sector-shaped tubular section 18 having side walls of an inverted V-shape in cross section. lhe inner and outer diverging tubular flanges of the section 18 form between them an annular groove 19 to receive the upper edge of another tubular section of similar construction, and so on throughout a series of tubular sections similarly positioned with their corresponding parts alined so as to produce a curvature or bend and form a flexible elbow, the pivot connections 17 being in alinement along the opposite sides of the bend. The play of each tubular section in the groove of the section thereabove enables the angularity of the bend to be greater or less without disturbing the tubular form of the elbow and without opening the joints.

The spout is preferably composed of two flexible elbows reversely bent and connected by an intermediate telescoping section comprising an upper tubular member 20 with a single edge at its upper end pivotally connected in the groove of the lowermost section of the upper elbow and with its lower end formed of concentric tubular parts spaced apart to receive the lower tubular member 21 which has a telescoping fit there between and has a pair of concentric diverging flanges 22 at its lower end to receive the upper edge of the uppermost section of the lower elbow.

The lowermost section of the lower elbow comprises a tubular member 23 surrounded by a flanged collar 24 secured thereto and swivelly mounted in a ring 25 on a bracket 26 carried in any suitable manner by the truck 27 of the car directly in front of the car wheel 28 and terminating a short distance above the rail 29. At the lower end of the tubular member 23 there is an annular flange 30 concentric therewith and spaced therefrom to form a comparatively deep annular groove in which are pivotally mounted a pair of curved lip members 31, the pivot points 32 thereof being so positioned relative to the center of gravity of the lip members as to cause said members to normally hang in a closed position, as shown, but permitting of their swinging away from each other under the weight of sand discharged through the spout, as shown by dotted lines, and then serving to spread the sand over the head of the rail 29.

By means of this" invention the sandfrom the sand box is conducted through an all metal spout to a point close to the rail and directly in front of the car wheel, and this, irrespective of the direction of travel of the car, that is to say, thevpoint' of delivery'remains the same when the car body is shifted relativeto the car truck onturning curves and when the car is traveling on a straight track.

The vertical 1 and horizontal swinging movements of: the carbody with relation to the truck) in no way. aflect the operation of the discharge spout, for the lower member thereof remains in its fixed position and the change:.in-position.of the upper member is permitted by the telescoping of the members20cand 21, the'pivotal movements of all members initheir connection witlreach other and the swivel movements of the members 1etand23a Not only are all of thesuri'aces so related as to avoid the formation of pocketszor ledges withinthe spout for holding sand or retarding its flow, but on the exterior; of the'spoutthey are so overlapped as to: shed water; and. prevent the parts freezing; Also, the automatically closing swinginglip members 31 prevent the spout becoming clogged with sand'andiice, sothat the: device will'remain operative at all times, andbeing; constructed 0]": metal itv will be durable and not liable to injury.
