LOCOMOTIVE SANDER.

Application filed July 19, 1926. Serial No. 123,35.

This invention is a novel improvement in locomotive sanding devices and the principal object of the invention is to provide a pair of novel devices adapted to beconnected with the two side outlets of the usual sand dome of a locomotive at each side of the locomotive, and each device having plurality of sand leads, operated by individual air nozzles, connected therewith, the leads respectively conducting the sand to the track aldjacent'one of the driving wheels of the locomotive.

Another object of the device is to provide a pair of novel sand columns, adapted when attached to the sand dome, to fit closely to the side of the boilercasing of the locomotive and to lie substantially tangent thereto, whereby the heat of radiation from the boiler oi' the locomotive will always main- 29 tain the sand in a dry state in the sand columns and sand leads, and thus prevent (raking of the sand within the sand columns and leads. n still further object is to pro vide a sand column having a relatively large opening at itstop registering with the opening in the bottom portion or the sand dome of the locomotive, whereby the sand from the dome will fall freely into the sand column and maintain the latter filled with sand. A still further object is to provide a sand column having a flange at its upper end disposed at an angle to the axis of the column, so that when the flange is bolted to theside oi the sand dome, the column will lie substantially tangent to the boiler casing of the locomotive.

lVe will explain the invention with reference to the accompanying drawings which illustrate one practical embodiment thereof to enable others familiar with the art to adopt and use the same and will summarize in the'claims the novel features of construction, and novel combinations or" parts, for which protection is desiredi Insaid drawings:

Fig. at is a longitudinal section on the linedl,Fig. l v

Fig. 5 is a-transverse section on the line 5-5,'Fig. 3. i l

As shown in drawings, the sanding device preferably comprises a tubular sand column 1, preferably a casting of suitable length and'diameter, the lower end or" the sand column 1, being internally threadedjas at l to receive a removable plug 2,*a dap'ted to be screwed into the lower end of the column'l, whereby the plug may be removed to permit access to the interior of the column. The upper end of sand column 1 is provided with a flange 1* preferably formed-integral with the column 1 and disposedat an angle to the longitudinal axis of the column 1,"the angle preferably being about 3O ,'whereby when the flange is bolted to the sand aomen with the opening in the top of the sand column registeringwith the outlet'in the bottom of the sand dome, as shown in Figs. 1 and 2, the sand column 1 will lie substantially tangent to the boiler casing otthe locomotive, whereby the heat of radiationol' the boiler will always maintain "the sand within the column in a dry state. The flange 1 is perforated, as sliown to receive the bolts .or other means for lasten-ing the flange to sand dome D.

Extendng substantially radially sand column 1, are a plurality'of sand ile ads 3, 61- and'y5.said leadsalllying preferably in'the same plane, but having their longitudinal axes slanting slightly upwardly to from ward the inlet orupper end of the sand column 1, as shown Figs. 2 and 3 to preventthe sand from normally 'discharging rrom the sand leads hereinafter described,

by gravitation. The sand leads each'preferably comprise a short length of pipe of suitable diameter, having their inneren ds screwedinto outlet ,orifices 1 in the side oi the sand coluinnl as shown in the drawingf'The orifices 1 are substantially spaced 7 equal distances apart, the upper orificefbeing disposed on the right hand side of the sand column, (Figs. 2 and 3), and the two lower orifices being disposed on the left hand side of the column, as vlewed 1n sald figures.

' At the outer ends of leads 3, 4 ande are heads 3, l" and 5 respectively, said head's comprising tubular members screwedonto the outer ends of leads 3, 4 and 5, said respective lead 3, 4'. or 5.

heads having plugs 3, e and 5 in the outer ends respectively, whereby access may be had to the interior of the sand leads 3, at and 5. Heads 3 i and 5 are furthermore provided with angularly disposed branches 3, 4 and 5 respectively which are preferably internally threaded as shown and adapted to be connected to the sand pipes, 6, 7 and 8 respectively, which discharge sand on the track adjacent the driving wheels of the locomotive. Branches 3, i and 5 are preferably disposed at angles of about 45 to the longitudinal axes of the heads.

in the heads diametrically opposite to and substantially in line with the sand pipe branches are perforated lugs 3 et and 5 respectively, which are preferably threaded to receive the blowout air piping hereinafter described, which assists in discharging sand from the sand column and leads down through the pipes 6, 7 and 8 respectively.

Airnozzles are provided for each sand lead 3, t and 5, eachnozzle comprising a short nozzle 1, extending through the casing 1. at a point substantially tangent to the interior diameter of the sand column and in line with the axis of its respective sand lead 3, 4: or 5, said nozzle having its outer end bent into alignment with the aXes of its respective sand lead, as shown particularly in Fig 5, the nozzle 1 being disposed substantially at right angles to the axis of its The casing 1 adjacent each nozzle 1 is preferably enlarged and provided with an internally threaded bore 1*, communicating with the nozzle 1 said threaded bore 1 being adapted to receive the usual air plug 1 attached to'the end of the main air pipe feeding the nozzle. Each plug 1 is preferably provided on its inner end with a plate 1 having angularly disposed openings 1 therein through which the air freely passes to the nozzle 1 while preventing sand from passing from the nozzle and back into the air line'past the plate 1.

Asshown in Fig. 2 the blowout lug 41 is directly connected to an air pipe 9 leading from a suitable source of air supply, the

pipe '9 being controlled by a valve preferably operated in the cab of the locomotive. Blowout lugs 3 and 5 are both connected to an air pipe 10 which is likewisepreferably valved, the valve being operated in the cab of the locomotive, whereby air may be passed through either blowout pipes 9 or 10 separately or simultaneously, as desired.

The nozzle 1 for the sand lead 4 is connected to a main air pipe 11, controlled by a valve situated in the locomotive cab and operated in the same manner as the valves controlling air pipes 9 and 10. The air nozzles for sand leads 3 and 5 are both connected to an air pipe 12 similarly controlled by a valve in the cab of the locomotive.

The sand pipes 6 and 8 are arranged to discharge sand on the track immediately in front of the two front driving wheels of the locomotive, while the sand pipe 7 is arranged to discharge sand on the track immediately in the rear of the rear driving wheel of the locomotive. Hence, when it is desired to sand the track when the locomotive is moving, or about to move, in the forward direction the valve passing air through air pipe 12 to the nozzles of sand leads 3 and 5 alone would be operated. If desired to sand the track when ihe locomotive is moving, or about to move, in the reverse direction, the valve passing air through air pipe 11 to the nozzle of sand lead a alone would be operated, the nozzles for sand leads 8 and 5 being arranged to operate simultaneously, and the nozzle for sand lead t being arranged to operate independently of the nozzles for leads 3 and 5.

f sand should become caked or clogged in the heads 3 and 5 the valve of pipe 10 may be opened permitting a blast of air to blow out and clear the heads 3 and 5. Similarly if head t should become caked or clogged with wet sand, then the valve of pipe 9 may be opened admitting a blast of air through lug P to clean out the head et If desired the valves of pipes 10 and 12 or 9 and 11 may be opened simultaneously to produce a max imum air blast not only in the column 1 but in the heads of the sand leads.

By placing the column 1 in the position shown in the drawing, the heat radiating from the boiler casing will maintain the sand in the columns dry and hot at all times, and thus prevent or largely eliminate caking of the sand in the columns or leads.

While we have shown three sand leads extending from each sand column, any number of leads may be applied thereto according to the requirements of the particular locomotive. The large opening in the top of the column registering with the opening in the lower portion of the sand dome will permit the sand column to be filled with sand from the dome at all times.

We do not limit our invention to the exact form shown in the drawings for obviously changes may be made therein within the scope of the claims.

We claim:

1. A sander for a locomotive having a sand dome; comprising a casing provided with a plurality of sand outlet orifices; sand leads connected with said orifices and having their axes slanting slightly upwardly; air nozzles extending into the casing opposite said outlet orifices; and said casing having a coupling flange at its upper end lying in a plane at an angle to the longitudinal axis of the casing, whereby when the casing is attached to the sand dome of a locomotive the casing Will lie substantially tangent to the locomotive boiler casing.
