COAL CARRIER FOR TENDERS.

Application filed May 13, 1926. Serial No. 108,877.

This invention relates to coal carriers for locomotive tenders and has for its object to produce means whereby the fireman can always maintain the pile of coal close to the front end of the tender andnot have to spend a good deal of his time walking back and forth the length of the tender in order to obtain coal for feeding the locomotive, and also to obviate the employment of an extra hand or coal passer to shovel the coal to the front end of the tender.

lVith the general objects named in view and others as may hereinafter appear, we have produced a strong, ellicient, durable and inexpensive construction; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which v Figure 1 is a side View of the rear end of a locomotive and tender equipped with apparatus embodying the invention.

vFigure 2 is a top plan view of the same, with the locomotive cab omitted.

Figure 8 is a section on the line III-III of Figure 1.

Figure 4 is a side view of the tender, partially broken away to disclose parts otherwise hidden.

Figure 5 is an enlarged top plan view of the locomotive drivers with apparatus forming the power mechanism.

Figure 6 is an enlarged view of the control mechanism for clutching and unclutching the device.

In the said drawings, where like reference characters identify corresponding parts in all of the figures, 1 indicates the locomotive cab and 2 the locomotive tender.

The coal carrier comprises a relatively L-shaped scoop comprising a bottom member 3, a rear wall 4 and side walls 5, the side walls being braced by inclined braces 6, said carrier being of suicient width to extend from side to side of the tender.

The rear bottom corners of the carrier are preferably formed with upstanding housing portions 7 within which are journaled rollers or wheels 8 on a transverse shaft 9, the front edge of said carrier scraping or sliding over the bottom of the tender. It will be understood that in normal position when the tender is to be loaded with coal, the carrierwill stand atthe rear end of the tender and against the back wall thereof. tomary.

As the engine is tired and the coal is gradually shoveled by t-he fireman away from the front end of the tender, the fireman turns a control wheel 10 fixed to the end of an inclined rod 11 journaled in a bearing 12 carried by theioor of the tender. The other end of the rod extends below the floor of the locomotive cab and is equipped with a universal joint 13 connected to a shaft l-t journaled in a bearing 15 depending from the floor of the locomotive cab l.

The end of the short shaft 14 carries a disk 16 from the face of which projects a pair of pins 17. R-otat-ively secured to the pins 17 and normally standing in the position shown in Figure are a pair of curved links 18, it being evident that the parts as shown in said ligure have passed center and the device is locked against accidental operation.

The ends of the links 18 are each pivotally secured to pins 19 carried by straps 2() loosely encircling a driving axle 21 of the locomotive. The straps .40 are each litted between a pair of plates 22 and the ends of a pair of cable reels 23 freely mounted on the axle 21. Secured to substantially the center of the engine axle 21 is a fixed abutment member 24 and between the opposite sides of said member and the plates 22 are a pair of expansion springs 25.

The outer ends of plates 26 of each of the cable reels 23 are formed with a notch 23a, and lixedly secured to the engine aXle are a pair' of pins 27 for driving engagement with the notches 23. It will be evident that the fireman by rotatingr the operating rod 11 can release the cable reels so that notches 23a shall engage the pins 27 and power shall be applied to rotate the cable reels, the springs assisting the fireman in sliding the cable reels longitudinally of the axle 21. It will be understood that this is done only when the engine is travelling at a low rate of speed.

Coiled around each of the reels 23 are cables 28 which lead rearwardly and upwardly over guide pulleys 29 and are secured at their ends to the front corners of the coal carrier. It will be apparent from the mechanism described, that the fireman can effect the forward movement of the coal The coal is then loaded as cus- U carrier and thus maintain the coal in close proximity to the fire box.V It will be apparent that the vfront end et thewcarrier xby scrapingonlthe Hoor of the tender Willv positively effect the movement oi' all of the coal torn/ ardly, n and that as theY greater oi' the Weight of the coal Will-be carried bythe rollers S no undue strain Willbeplaced on the cables or operative mechanism'.

In order to return thecarrier to,j normal position, a transverse shaft 30 is journaled in bearings 31 atthe rearfnd of the tender, and mounted on the ends of said shaft arearpair or Wheels enineshed with chains 63 extending forwardlyv and upwardly and gn- Circlng. a pair of gear.
