SPECIFICATION forming-,part of Letters Patent No. 752,954, dated February 23, 1904;

I Application led November 12, 1903. Serial No. 180,946. (No model.)

To all whom it may concern,.- Y

Be it known that I, IRA P. CARNES, a citizen of the United States, residing at Lima, in the county of Allen and State ofpOhio, have invented new and useful Improvements in Pneumatic Sanders, of which the following is a speciication. Y

This invention relates to certain new and useful improvements in pneumatic sanders for locomotives; and the object thereof is to provide a new and novel sander whereby a blast of air may be used to discharge sand or other suitable material on the rail section or sections of a railway-track either in front of or behind the driver or drivers of a locomotive.

A further object Vof the invention is to construct a pneumatic sander for the purpose set forth which can be reversible, so as to permit of the removal of anyforeign bodies that may collect within the device.

A further object of the invention is to construct a pneumatic sander for the purpose set forth, so that free access can be had to the air-nozzle if it becomes clogged or closed, so that the same can be cleaned without the removal thereof or the removal of any of the pipe connections. n

A further object of the invention is to construct a pneumatic sander for the purpose set forth with an integral air-nozzle arranged directly opposite the discharge-opening of the sander and to further provide the sander with a pair of duplex openings, one of which forms the inlet for compressed air and the other of which is closed by a removable plug, so that by removing said plug access may be readily had to the nozzle should the sameY become clogged or closed, so that the said nozzle can be cleaned without removing it or any of the pipe connections.

A further object of the invention is to construct a pneumatic sander for the purpose set forth with an integral air-nozzle and -a pair of duplex openings, one forming the inlet for compressed air and the other closed by a removable plug for the purpose set forth, said plug being suitably bored for establishing communication between the air-inlet and the nozzle.

A further object of the invention is to convstruct a pneumatic sander for the purpose set forth which shall be extremely simple in its construction, strong, durable, reversible, etlicient in its use, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of the novel'combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like reference characters denote corresponding parts throughout the several views, and in whichn Figure -1 is a side elevation of a portion of a locomotive, showing the sander connected therewith. Fig. 2 is a side elevation of the sander. Fig. 3 is a section on the line 3 3 of Fig. 2, and Fig. 4 is a section on the line 4 4 of Fig. 2.

Referring .to Fig. 1 of the drawings, 1 denotes a portion of a locomotive; 2, the sander; 3, the air-pipe; 4, the sand-supply pipe, and 5 the sanding-pipe. When the sander is in "position, the pipes 3, L1, and 5 communicate therewith, as shown in Fig. 1; but it is evident that the pipes 3 Vand 5 may be so connected' to the sander 2 that the pipe 5 extends at the rear of the driver and not the front thereof.

Referring to Figs. 2, 3, and 4 of the drawings, 6 denotes a casting substantially cylindrical in contour and provided at one side intermediate its ends with an enlargement or oifset 7. The front wall 8 and the rear -wall 9 of said offset is substantially arch-shaped. Each end of the casting 6 is provided with interior screw-threads 10, and the wall 8 of the offset or enlargement 7 is formed with ascrewthreaded opening 11, the opening 11 being the discharge-opening of the sander. The wall 9 of the offset or enlargement 7 is provided with an integral air-nozzle 12, arranged opposite the openingll. Projecting from the wall 9 of the olfset or enlargement 7 is a casting 13,

which is of such size as to form an air-charnber 14 and has one of its walls provided with

duplex openings

15 and 16, the walls of which are screw-threaded. The opening 15 has connected thereto the air-supply pipe 3, and this opening 15 is termed the air-inlet of the sander. The opening 16 is closed by a screwthreaded plug 17, the inner end of which' is seated in a recess 18, formed in the wall 9 of the offset or enlargement 7. The plug 17 eX- tends in alinement with the nozzle 12 and is provided with a port or passage 19, which eX- tends in a horizontal and longitudinal manner, and the longitudinal portion of said port or passage 19 registers with the bore 20 of the nozzle. The latter is or may be of greater diameter than the port or passage 19. The

port or passage 19 establishes communicationv between the air-chamber 14 and the nozzle. The plug 17 when removed permits access to be had to the nozzle for cleaning it if the nozzle should be clogged or stopped up, and it is evident that the cleansing of the nozzle can be effected without disconnecting the air-pipe 3, which is connected to the opening 15, or the sanding-pipe 5,which is connected to the opening 11, or the sand-supply pipe 4, connected to one of the openings 10. When the pipe 4 is connected to one of the openings 10, the other of the openings 10 is closed by a removable plug 21, Fig. 1. It will be evident that the sander can be reversed, owing to the pro- 'viding of the sander with the two screwthreaded openings 10, and that by removing the plug 21 any foreign bodies, such as stone and gravel or the like, can be discharged from the sander. rlhe end of the sander in which the plug 21 is secured forms what may be termed a trap.

It is thought the operation of the sander can be understood from the foregoing description, taken in connection with the accompanying drawings; but it will be stated that the sand being supplied by the pipe 4 the compressed air in the chamber 14 will pass through the port or passage 19 and into the nozzle, where the action of the air will force the sand to the track section or sections at the front or rear of the driver or drivers. The compressed-air pipe 3 can be connected vto an air-reservoir or' to an air-exhaust.

It is thought that the many advantages of my improved pneumatic sander can be readily Aunderstood from the foregoing description,

` annexed drawings, but reserve the right to make such changes, variations, and modications as come properly within the scope of the protection prayed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
