A,To dirname it 'may cof/teem:

Be 1t known that I, EDGAR A/lNDiiRsoN7 a citizen of the United States, residing at Alto Pass, in the county-oi Union and State of lllif l tender into the firebox of the locomotive.

Qne obiect Oi the invention is to provide a eonveyer of the above description which will automaticall convey coal orfthe like.

videv a means for depositing the coal on thev y Another o. ject of the invention is to prograt-e in the series of predetermined positions Y so that the saine may be conveniently dis tributed. I

A stili further object of the invention is to provide means whereby the conve er may be cooledl after passing into the iireox. `With these and other objects in -view as will appear from the detailed description of the device the invention consists in certain novel form, theconstruction,.combination of arts and arrangement of elements herewith v y described, illustratedin the accom i anying-drawings and specifically set forth 1n the claims. .Y ln vthe accompanying drawings; Figure 1 is a section taken longitudnallythrou'gh a vportion o'fhar locomotive and tender showing the device 'as applied theretothe'illustration partly diagrammatic. Fig. 2 is a transverse view partly in section of the locomotive fire-box. Fig. 3 is a detail of the inanner of mounting-'the tip buckets on the preferred manner a gratiwhereof 16 indi-- eates thelive grate and 17 the dead grate.

'At 18 `is formed a door extending substantialll acrossthe entire Width of the sheet 13 as 1l ustrated plainly in' Fig. 2.

At19 is formed the usual ash pan, in'this I Speeii-ieation of etters atent. appntas'paaieairmh 2e, isos. e serial No. 422,693.A

instance provided with an opening 2G com-- mensurate with an opening 1'8 in the firebox- The conveyor itself comprises a plurality of endless link belts 20 running over a series of sprockets now to be deseri bed; the sprocket 21 is held in suitable brackets adjacent the door 13. Within the fire-box is mounted a sprocket 22 arranged to carry one of said chains. This sprocket being positioned so that the chain assing therethrough together with the parts eld thereon will move downward thrdugh a suitable opening 23 in the dead grate-and then around a sprocaet 24, from the sprocket 24 the chain is carried toward the tender over a sprocket 25 situated vat the rear of the fire-box. The tender 26 is provided with any desired form of tank as at 27 preferably having a vertically disposed front end 28. A supplemental tank 29 is "preferably heid below the iloor of the tender f as shown in Fig. 1. A sprocket 30 is arranged to receive the chain passing from the sprocket 254before referred to and a sprocket 31 is held in the supplemental tank 29 to cause said chain to dip belowthev surface of the Waterlindicated therein. The chain after t leaving the sprocket 31- passes upward substantially parallel to the end sheet of the tank' 28 and over a sprocket3f2 from whenceit returns to the sprocket 21. Attached toone of said sprocketsis provided any suitable motive power not deemed necessary to be here shown.

.In the device as here lillustrated there has been shown a pair ofchains arranged on' opposite sides of the fire-'box and it is of course obvious that each chain have its own series of Vsprockets oppositely disposed.'

Pivotally mounted onrods 33 extending from one of said chains to the other and securely fastened thereto are tip buckets 34 cach provided With a inger 35 secured at the rear end thereof. In the preferred form of this device these buckets are arranged so` that there will be a number of setsv thereof in each of which the fingers 35'will have varying heights. Within the fire-box is mounted a means for tipping said buckets preferably comprising a ar 36 provided with i series of downwardly depending fingers 37 arranged to lie in the path of the fingers 35 on .the tip bucket. These fingers are preferably equal ric ' in Fig. 1.

in numberto the number oi"v sets of tip buck- 1 through 'ets and are of such length that eachA one will contact with the iinger of the set it is adapted to operate and tip the buckets of that set. A series of similar ngersv 38 are held Within the tank 29 and replace said buckets after having beentipped. In order to hold the buckets securel in position While the coal is loaded thereon ars 39 are held on the chains extending from oneto the other and on these bars is mounted a cross-bar'40 carrying a sleeve41 provided with a hook-42 formed thereon. A slpring 43 is mounted on the bar 40 to norma y press said .hook out of engagernent with the bucket 34. To cause said hook to engage the bucket 34 ratchet bars 44 are mounted in the tender adjacent.

the vertical path of the conveyer as indicated Carried upon the sleeve 41 are a pair of resilient arms 45 having heads 46 thereon arranged to engage the ratchet bars 44 as shown in Fig. 4. Now it is. to be observed that as the `arms 45l are drawn along over'the ratchet bars 44 the spring 43 will be compressed and the hook 42 be caused to engage the b ucket 34 thereby holding the same rom tipping. v

In order to vprevent the 'coal dropping vdown into the supl lemental tank 29 there is fprrovided a trap oor 47 arranged to move` eely upward and 1 permit passage of the buckets as indicated in Fig. 1. In order to transversely feed the coal there are also lprovided trap doors 48 and 49 as shown in the same figure.

In the operation of the device as the buckets pass upward from the sprocket 31 to the sprocket 32 they will be vloaded AWith coal b eing held from tipping by the means illustrated in Fig. 4 land previously described. As these buckets pass along intopthe fire-box they are tipped by the coaction of the fingers 37 and 35, each one bein dis osed in proper position to uniformly istribute the coal. They then pass outward through the dead grate vand over the sprocket 30 at this point the fingers 38 operate to right the buckets from the vertical position on the .chain and they pass downward through the Water'being there cooled.

It isobvious that many minor changes may be made in the form and construction of the device Without departing from the principles thereof and it is not desired to confinethe invention to the-exact form herein shown and described but it is wished to cover all such as properly come Within the scope thereof:
