Thisinvention relates to locomotive tenders particularly constructed to receive a novel form of fuel pusher means for moving the fuel forwardly in the tender bin from the rear to the front thereof, placing 4it within convenient reach of the reman for delivering it to the locomotive flrebox.

`In apparatus o f this type it has been customary toplace the operating mechanism for the fuel pusher in the fuel bin at its upper rearward end. One of the objects of this inventionV is to provide a novel tender and fuel pusher construction in which the pusher operating mechanism may be made more accessible and occupy nov space in the fuel bin.AV Y

4It is afurther object of the invention to provide` a novel fuel pusher and operating mechanism therefor that is simple in construction, compact in design and arrangement and efficient in operation.,

Other objects and advantages of the invention will become apparent from the following description when read iin connection with the accompanying, drawings, in Vwhich 1 is a central, longitudinal vertical section of the forward portion of a locomotive tender with the invention applied thereto;

Fig. 2 is a sectional View taken on the line 2--2 of Fig. 1; l

Fig. 3 is a centraLlongitudinal vertical section of the forward portion of a locomotive tender with an alternative form of the invention applied thereto; and

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 3.

On the drawings, referring more particularly to the preferred form of the invention illustrated in Figures l and 2, a locomotive tender is indicated generally at I0, comprising the fuel bin II and the water compartment I2, the two being separated' by 'the rear slope sheet I3, side slope sheets I4 and I5 and the fuel bin bottom Wall or floor I6.A A coal pusher, generally indicated by the numeral I1, is mounted in the fuel bin II and arranged to reciprocate longitudinally over the surface of the rear slope sheet I3 and the fuel bin floor I 6.V The coal pusher I'I comprises a .plurality of pusher heads, shown as four in number, and indicated respectively by the numerals I8, I9, 20, and 2l. The pusher heads 20 and 2I which reciprocate over the surface of the fuel bin oor I6 are in tandem arrangement and rigidly connected together by the longitudinally extending tieplates 22 and 23. The pusher heads I8 and I9 which reciprocate over the surface of the rear (o1. 10a-2.3m

slope sheet I3 are flexibly connected together by a plurailty of links 24 and similarly connected with the rigidly attached pusher heads 20 and 2 I.

The pusher heads are provided with an abrupt forward'face 25 to carry fuel with them on their forward movement and a sloping back 26 permitting them to pass freely under the mass of fuel on their backward movement.

The rear slope sheet I3 is provided with a track 2'I along which the pusher heads I8 and I3 reciprocate. Y Along the intersection of the side slope sheets I4 and I5 and the bin floor I6 there are secured in place in a suitable manner guide bars 28 and 29 forming with the floor I6 guideways 30 and 3l respectively. The tie plates 22 and 23 are provided with the laterally extending flanges 32 and 33 respectively, arranged to be received in the guideways 3l! and 3| respectively, permitting longitudinal sliding movement of the pusher heads 20 and 2|, but preventing lateral and vertical movement.

The coal pusher I'I is operated by a reciproeating motor 34 which is rigidly secured tothe underside of thefloor I3 within the water tight vcompartment 35. The compartment 35 is formed by the upright Walls 36, 3l and 38 together with the tender frame 39 and oor I6 and is open at its forward end. The piston rod 40 is reciprocated longitudinally within the compartment 35 and beneath the floor I6 by the motor 34. At its forward end, the piston rod 40 is provided with a transversely extending arm 4I, which is rigidly secured thereto and reciprocates therewith. y

The tie plates 22 and 23 are provided with the depending flanges 42 and 43 respectively, which project through the longitudinal slots 44V and 45 respectively in the floor I6 of the fuel bin II and are secured in a suitable manner as by bolts 46 and 41 to the opposite ends respectively of the arm 4I.

It is apparent therefore, that not only is there provided an unusually compact arrangement, but also the driving mechanism is conveniently located for purposes of inspection and repair and takes up no room in the fuel bin.

In Figures 3 and 4 there is shown an alternative construction in which the lower end of the rear fastened with the pusher heads I8 and I9 in the same manner as in the preferred form of the device. A motor 5l for operating the pusher is mounted in the water tight compartment 52, which is formed by the upright walls 53, 54, and 55 together with the floor I6 and tender frame 39. The motor 5I is shown mounted on the frame 39 but obviously could be mounted from the underside of the floor IG as in the preferred form of the device.

A bracket 56 is securely fastened to the upright wall 53 in the compartment 52 and a lever 51 is pivotally mounted intermediate its ends from the bracket 56. A pitman 58 connects one end of the lever 51 with the pusher member 50 and a pitman 59 connects the other end of the lever 51 with the motor 5I.

In this form of the device, a somewhat larger compartment is necessary to house the driving mechanism than in the preferred form of the device but the advantages in other respects are the same.
