TRACK-SANDIN G APPARATUS.

Patented J'an. 26, 1909.

Application led. July 28, 1908. Serial No. 445,704.

To all whom it may concern.'

Be it known that we, FREDERICK L. ROB- INSON and JOHN MCOABE, citizens of the United States, residing at Cheyenne, in the county of Laramie and State of lllyoming, have invented a new and useful Track-Sanding Apparatus, of which the following is a specification.

This invention relates to track sanding apparatus for locomotives and more particuarly to Sanders of the type disclosed in Patent No. 844,618, dated February 19, 1907. In mechanisms of this character where sand can be delivered in rear as well as in advance of the driving wheels, it will be understood that the rear ander is seldom used, and then only in an emergency. As a consequence, sandbecomes packed therein, and this particular part of the apparatus is apt to become inoperative for that reason.

One of the principal objects of the present invention is to construct the mechanism so that fresh sand is constantly fed to both the rear and forward Sanders whenever the latter is used, thus avoiding the objection noted.

A further'and important object is to provide a simple form of air nozzle from which the sand is effectively excluded without interfering with the supply of air, said nozzle moreover being of a character that will permit its being cleansed without the necessity of dismantling the air connection.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a locomotive with the apparatus in place thereon. Fig. 2 is a form in elevation on an enlarged scale of a portion of the mechanism. Fig. 3 is a longitudinal sectional view therethrough on an enlarged scale. Fig. 4 is a detail sectional view on the line 4 4 of Fig. 3.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, the locomotive, which is designated by the reference numeral 5 is provided with the usual driving wheels 6 and with a reservoir or sand box 7. From Vthis reservoir on each side, leads a single sand conduit 8, the lower portion of which is in the form of a casing 9 having its bottom closed by a detachable plug 10. Leading from one side of the upper portion of the casing 9 is a sand-conducting pipe 1 1 that has its discharge end disposed in rear of one of the driving wheels 6. Leading from the opposite side of the casing 9 and at a lower point, is another sand-conducting pipe 12 that delivers in advance of one of the driving wheels 6, as will be evident by reference to Fig. 1. Air or motive fluid supply pipes 13, extending from the cab of the locomotive and provided in. said cab with any suitable controlling means, are connected to nozzles 14 and 15. rFliese pipes furthermore have branches 16 extending over the locomotive to the sanding apparatus on the opposite side, as will be evident by reference to Fig. 1.

Each of the nozzles 14 and 15 comprises a tapered body 17 having` a portion threaded as shown at 18 into one side of the casing 9. Thus in the present embodiment the nozzle 14 is located opposite to the inlet end of the pipe 11 and in line therewith, while the n0z zle 15 is arranged opposite to and in line with the inlet end of the pipe 12. Jam nuts 19, threaded on to the nozzles, abut against the sides of the casing to securely maintain the nozzles in position. It will be noted that each nozzle is provided with a longitudinal bore 20 extending entirely through 'the same and an inclined lateral supply port 21 communicates with this bore between its ends. The pipes 13 are in communication with the ports 21. Inasmuch as the inner ends 22 of the nozzles extend across the casing, enter the inlet ends of the pipes 11 and 12, and are of less cross sectional area than said pipes, it will be evident that air supplied through these nozzles will be projected longitudinally into the inlet ends of said pipes, and, forming partial vacuums in the casing, will cause the sand to be drawn into the ipes and delivered either in advance of or behind the wheels. The outer ends of the bores 20 are closed by plugs 23, and carried by the inner ends of these plugs are stems 24 that extend longitudinally through the bore, being of less cross sectional area than the same and spaced from the walls of the bores. In the lateral ports 21 are turning valves 25 having intersecting ports 26 and 27 of different diameters. These valves are fully covered by the prior patent, to which reference has already been made.

Particular attention is called to the fact that the pipe 12, which conveys sand to a oint in advance pf the dri-vers., `is located ower than the pipe 11. As already `stated. the Jforward sander is used ,much more than the rear sander, and it will'be evident that ,in

this construction all the sand, which is passed through said forward sander, vor in vother words, through the .pipe 12, must pass through the upper .portion of the casing, and consequently past the rear sander 11. There is thereiore no chance of the sand becoming packed in the rear sander, and the latter is always ready tor use.

lt rwill be evident by reference to Fig. 3 that this structure is very simple, and there are decided advantages for the particular' form of nozzle employed, in the iirst place, the stem 24 excludes grains of sand from entering the nozzle, and the valve 25, being located above the bore, is completely protected from the dirt. However, should it become necessary to cleanse the bore, the plug 23 and stem 24 can be readily removed without dismantling the connection oi the pipe 13 with the nozzle.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size,shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificingany ofthe advantages oi the invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is :i
