OSCAR JOHNSON, OF CHICAGO, ILLINOIS.

LOCOMOTIVE-TENDER.

Specification of Letters Patent.

Patented Jan. 2,1912.

Application filed April 1, 1911. Serial No. 618,274.

To all whom it may concern:

Be it known that I, OSCAR JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Locomotive-Tenders, of which the following is a specification.

My invention relates more particularly to improvements in devices used in connection with fuel-bins, for moving the fuel toward the front end of the bin to render it readily accessible as for stoking a furnace, and to improvements generally in locomotive tenders.

My objects are to provide a novel and simple construction of coal-moving device for the purpose stated; to provide a tender having inlet-openings communicating wit-h the water-tank thereof, so arranged as to permit the spout of the stand-pipe at the side of the track, from which the tender is supplied with water, to be readily brought into communication with the interior of the tank without requiring as accurate position ing of the tender with relation to the standpipe, as is required with constructions ordinarily provided; to overcome impairment of the water-tank of the tender by corroding of the joints thereof due to the chemical action of the coal upon the metal as is common in constructions as hitherto provided; to provide, in connection with the usual siphon-pipe leading from the tank to the engine, means whereby shifting of the water in the tank will not destroy continuity of the siphon-action; and to improve generally upon tenders as hitherto provided.

I have devised my improved fuel-handling device for use, more particularly, in connection with locomotive tenders, and have therefore illustrated it in this connection in the drawings, a description of which is as follows:

Figure 1 is a plan view of a tender constructed in accordance with my invention. Fig. 2 is a view in side elevation of the same, with a portion of the tender broken away to disclose the interior details. Fig. 3 is an enlarged, broken, section taken at the line 3 onFig. 1 and viewed in the direction of the arrow. Fig. 4: is a view in end elevation of the construction illustrated in Fig. 1, the tender in this view being viewed from the front end thereof. Fig. 5 is an enlarged section taken at the line 5 on Fig. 2 and viewed in the direction of the arrow. Fig. (3 is a section taken at the line 6 on Fig. 3 and viewed in the direction of the arrow. Fig. 7 is a broken view in longitudinal sectional elevation of the mechanism for operating the coal-moving device with which the tender is equipped. Fig. 8 is a broken see tion taken at the line 8 on Fig. 3 and viewed in the direction of the arrow. Fig. 9 is an enlarged section taken at the line 9 on Fig. 3 and viewed in the direction of the arrow. Fig. 10 is a section taken at the line 10 on Fig. 3, and viewed in the direction of the arrow; and Fig. 11, a broken section taken at the line 11 on Fig. 3 and viewed in the direction of the arrow, this view being taken through one of the side walls of the fuel-bin of the tender.

The under structure of the tender comprises a series of longitudinally-extending channel-irons 12 which form supports for the axles 13 carrying the wheels 13 of the tender. The water-tank of the tender, which is represented at 14, is located at the rear end of the tender and its forward wall 15, which is integral with its bottom plate 16, forms the rear wall of the coal-bin 17 of the tender, the tank being secured to the channels 12 in any suitable manner.. The side-walls of the bin 17 are formed of plates 18 which extend forwardly from the plate 15, and throughout certain portions thereof are formed with lining-plates 19 which are spaced from the plates 18 and are secured to the latter through. the medium of Z-bars 2O fastened against the inside of the plates 18, the space between the plates 18 and 19 being filled with planks 21 with angle-irons 22 interposed between adjacent planks. The bottom of the bin 17 is formed of a front, substantially horizontal, plate 28, and a rear plate 24 which extends downwardly toward the rear end of the tender. The plates 23 and 24 are supported on I-beams 25 extending transversely of the tender and resting against a plate 26 which is joined to the plate 16 and rests upon the upper surface of the channel-irons 12. If desired, the front end of the tender may be provided with vertically-disposed compartments 27' located at opposite sides thereof and spaced apart, the compartments 27, which may be equipped with doors 27 and serve as containers for tools, etc, in the construction shown, being formed by bending the front ends of the plates 18 to the desired shape.

Furthermore, the space between the front ends of the plates 23 and 26 may be utilized as a compartment, access thereto being had through doors 28.

At 29 valved siphon-pipes are indicated, these pipes extending through the upper end of the bin. 17, at their front ends downwardly through the compartments 2? where they are attached to pipes leading to the engine, and at their other ends downwardly through the top wall of the tank into receptacles 30 located below the level of the plate 16 and opening into the tank, these receptacles constituting wells which are of such a size as to insure the retention of water therein at all times regardless of the shifting of the water in the tank, whereby the siphonaction is rendered continuous.

The manholes through which water is supplied to the tank 14 are represented at 31 and are of elongated form as shown, these openings extending one in advance of the other and staggered with relation to the median line of the tender, each of these openings extending on opposite sides of the median line as represented in Fig. 1 and being provided with hinged covers 32. By thus providing openings 31, each extended beyond the median line of the tender in both directions and close to the sides of the tank, thereby affording relatively great range within which the tender may be positioned with relation to the stand-pipe, the necessity of positioning the tender with the accuracy required in cases where such disposition of the openings is not provided for, is avoided. Furthermore, in this construction, so far as the operation of the tender is concerned, the manhole openings, while giving the same results as a single opening extending across the top of the tank for almost its entire distance, are not subject to the disadvantages of a single opening, as two separatel operative covers 32 are employed, which renders them relatively easy to operate.

The bin 17 is provided with means whereby, as the supply of coal therein becomes reduced, the remaining coal may be shifted toward the open, front, end of the bin, to render it readily accessible to the firemen, and thereby avoid the objection of compolling the firemen to go to the rear end of the bin for the coal when the supply becomes reduced, the description of such means being as follows: Hinged at its upper end, as indicated at 33, on a rod 34 secured at its opposite ends in the sides of the bin, is a depending plate 35, reinforced as by angleirons 36 and hinged at its lower end, as indicated at 37, to an apron 38 which extends forwardly and normally rests at its free end upon the inclined plate 24 as represented in Fig. 3, it being preferred that the lateral edges of the plate 35 and apron 38 be equipped with packing strips (not shown) which brush against the inner sides of the plates 19 when the plate 35 and apron are swung as hereinafter described and prevent undue escape of fine particles of coal between the plates 19 and the movable plate and apron. Secured to the plate 35, near its lower end and at opposite sides thereof, are cables 39 which extend upwardly through the bin 17 and pass over sheaves 40 journaled on rods 41 secured in the walls 18 and in deflected plates 42 secured to these walls, the cables 39 thence passing downwardly through the plates 23 and 26 and being rigidly connected at their free ends with sheaves 43 fixed on a shaft 44 journaled in bearings car ried by the channels 12. The shaft 44 carries a third sheave 45 rigidly secured thereto and with which one end of a cable 46 is secured, the cable 46 passing about the sheave 45 in the direction opposite to that in which the cables 39 pass about the sheaves 43. The other end of the cable 46 is connected with a piston-rod 47 which carries a piston 48 slidably confined in a cylinder 49 connected with one of the channel-irons 12, as represented at 50, this cylinder, which contains an exhaust-port 52 at its rear end, communicating at its forward end with a valved steam-pipe 51 leading'from the engine.

The normal position of the plate 35 and its operating mechanism is that illustrated in Figs. 1, 3 and 5, in which the plate 35 is in depending position with the apron 38 resting upon the upper surface of the plate 24 when the piston 28 is at the forward end of the cylinder 49, the parts being in this position when the bin 17 is filled with coal. \Vhen the fireman, in using the coal from the bin 17, exhausts the supply at the front end thereof, he may move the remaining coal to the front end of the bin by introducing steam into the cylinder 49, through the pipe 51, thereby driving the piston 48 inwardly, with the result of turning the shaft 44 to the right in Fig. 3, which causes the cables 39 to be drawn down and the plate 35 and apron 38 to swing to the left in Fig. 3. Thus swinging the plate and apron, as described, causes the coal which lies in the bin 17 to be moved forwardly therein to the front end of the bin, where it is readily ac cessible to the firemen, the apron 38 in this operation riding upon the plate 24. lVhen the supply of coal in the bin has become so reduced that it is necessary to finally move the plate 35 and apron 38, as described, to the position represented by dotted lines in Fig. 3, all of the coal in the bin'will have been moved to the front end of the latter, and thus the firemen may remove allof the coal from the bin while standing atKthe open end thereof. When the piston has moved beyond the port 52, in which position the plate 35 Will be caused to extend as indicated by the dotted lines in Fig. 3, the steam will exhaust from the cylinder, and the plate 35 and apron 38 will swing to the normal position shown by full lines in Fig. 3.

To prevent clogging of the coal-moving mechanism, from fine particles of fuel which might sift between the plate 35 and the apron connected therewith and the walls 19, I provide openings 26 in the plate 26 which permit the fine particles thus escaping from the bin to fall through the plate 26 to the track upon which the tender runs.

It will be noted from the foregoing description that the coal in the bin 17 does not come in contact with any joints of the water-tank and thus danger of corrosion thereof from chemical action of the coal is prevented.

While I have illustrated and described my fuel-moving device in connection with a locomotive-tender, I do not wish to be understood as intending to limit it to use in this connection, as it may be used in any bin in which it is desirable to feed its contents, whether it be fuel, ore or other material to the outlet thereof to render it accessible as in the case of fuel for feeding a furnace. Furthermore, my'invention is not limited to the use of piston and cylinder mechanism for operating the plate and apron 38, as these last referred to elements may be operated in any other suitable manner. It is also to be understood that my invention is not limited to the operation of the piston by means of steam, as any other suitable fluid-pressure may be employed where the plate and apron are to be operated by fluid-pressure mechanism.
