LOGOMOTIVE ASH-PAN.

To all whom it may concern:

Be it known that I, LAWRENCE C. MOONEY, a citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain new and useful Improvements in Locomotive Ash-Pans, of which the following is a specification.

This invention comprehends certain new and useful improvements in ash pans for locomotives and dumping devices therefor, and the invention'has for its primary object a simple construction of hopper bottom slide controlled dumping ash pan, the parts of which may be easily made and assembled and the slides thereof easily controlled.

The invention also has for an object an .improved ash pan of this type which will effectually fulfil all of the requirements of the existing laws relative to the regulation and maintenance of devices of this character, which, in its use, will not present an element of danger to the road in that all liability of burning the ties of bridges, trestle work and other ties, will be precluded, and which will promote the thermal efficiency of the locomotive boiler furnaces by its capability of ease of operation and its property of discharging the ashes over a relatively large superficial area.

With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a locomotive ash pan embodying the improvements of my invention; Figs. 2 and 3 are, respectively, longitudinal and transverse sectional views through one of the hoppers; Fig. 4 is a top plan view of the hoppers and operating mechanism; Figs. 5 and 6 are detail perspective views of the parts of the operating mechanism; and, Fig. 7 is a detail perspective view of a handle that may be employed to manually actuate the discharge slides.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

pan equipped with the improved features of my present invention may be of any desired construction, type, or design, the one in the present instance being shown as embodying the usual front and rear chambers, and being preferably constructed of sheet metal, riveted or otherwise secured at the seams or edges and supported from the engine framework in any desired way, said body'portion, designated A, being provided with any desired number of screened openings 13, the screens being preferably securely held in place by marginal binding strips which not only serve as retaining devices for the screened panels or openings, but also serve to strengthen the sides of the pan.

My invention resides, essentially, in the bottom portion of the pan and embodies front and rear hoppers 1, each of which is preferably a single solid casting with up wardly flared side walls fitting over the bottom discharge ends of the front and rear chambers of the body portion A. Each hopper is secured to the body portion by rivets, as shown, there being two rows of these fastening devices in the present instance, namely, a top row and a bottom row, as clearly illustrated in the drawing. Each of these hoppers 1 is formed at its lower edge with an outstanding marginal flange 2 designed to directly support guide bars 3 secured to the flanges by bolts 4 or the like, as shown, and these guide bars are recessed in their inner sides, as indicated at 5, so as to form channels for the preferably cast iron slides 6, which work longitudinally therein and control the bottom discharge openings through the respective hoppers 1.

Each of these two slides-6 is formed, preferably at about its middle, with a depending transversely apertured lug 7, and said lugs are designed to fit down into longitudinal slots 8 that are formed in the opposite ends of a longitudinally extending connecting rod 9. The lugs may be secured to the rod in any desired way, as by bolts 10 passed through the apertures of the lugs 7 and through corresponding apertures in the slotted portion of the rod, the bolts being held in place by cotter pins, or otherwise.

At its rear end, the connecting rod 9 is formed with a horizontally disposed rearwardly projecting apertured lug 11 which is designed to fit in the forked end 12 of a link 13, a bolt 14% or other fastening devices being slipped down through the lug l1 and through apertures formed in the fork 12. The rear end of the link 13 is alsoforked, as indicated at 15, and'receives the apertured end of an actuating lever 16. A bolt, as shown, connects the forward end of this lever with the forked end 15 with the link 18, the link thereby pivotally connecting the lever with the rod 9.

The lever 16- is fulcrumed intermediate ofitsends in. the forked lower end 17 ofa hanger lswhich is riveted'or otherwise secured to-the engine framework and extends downwardly therefrom, and the rear end of theilever l6iis preferablytapered, as indicatedgat 16, whereby, ifit be desired to 0peratethe slide by hand, the socketed end 19 ofa handle 20 may be slipped over this taperedend of the; lever to rock the latter. Preferably, the apparatusis controlled by fluid pressure, such as steamer airand-to this endl provide an opera-ting cylinder. 21 provided at opposite ends with ports to which piping 22-is connected, said piping leading to, a,three-way valve (not shown) located in the engine cab. It is, of course, to be understood that there is apiston within the cylinder, 21, andthat by allowing the fluid to flow to, one end of the cylinderor to the other, the piston may be moved in one direction orthe reverse and said piston is connected.;to a rod whichhas a knuckle joint connection23 with a forked link 24 pivotally connected to the obliquely extending actuatinglever 16 forward of the fulcrum point ofthe lever, as clearly illustrated in Big. 4. Hence by admitting the fluidinto one end of the cylinder, the lever 16 may be rocked in one direction to open the bottoms of the discharge hoppers 1, andby permit-- ting the fluid to flow into the other end of the cylinder, the lever 16 may be rocked in the opposite direction to work the slides in a direction to close the discharge openings of the hoppers.

From the foregoing description in connection; with the accompanying drawings, the operation of my invention will be apparent. In the practical use of the apparatus, the operator, within the cab, may control the movements ofthe slides 6 and easilyopen the bottom discharge. openings of the hoppers 1, the entire hoppers being open so as to equally discharge the ashesover a relatively large area, the ashes being thereby spreadout and theliability of burning the ties being thereby reduced to a minimum.

Obviously, the device may be very easily controlled by fluid pressure, as above indicated, or if desired, should for any reasonfiuid pressure supply become exhausted or the fiuid pressure apparatus become inoperative for any reason, the handle 20 may be applied to the rearwardly projecting end of the lever 16 andothe ash pan dumpedlby hand.

It is to be particularly. noted that: in my construction of: ashpan, a single connecting bar is employed for the slides, the draft or pull of said bar, beingonthe exact median on center line oftheslides and thBxCOIlHGC- tion between said bar and the slides being, comprised in a singlelug 7 foreach, slide mounted in an elongated slot in the connecting rod witha single, connecting pin 10, the slots of the rod 9, as best seen in Fig. 3, being slightly wider than the lugs 7, by which entire arrangement-the-slides are permitted to adjust themselves in the channels of the guide bars 3, all binding or sticking being thereby effectually prevented.

Having thus described the invention, what is claimed as new is In a locomotive aslrpan of the character described, the combination with, the body portion ofthe pan, of'discharge hoppers embodying solid integral castings securedto the body, portion and providedwith longitudinally extending guide channels, slides mounted for movement in said channels,

each ofsaid slides being formed midway'betweenits side edges wltha longitudinally disposed and downwardly,pro ect1ng lug, a

single connecting rod formed at each end with a vertically.openinglongitudinally eX- tending slot in which; the lugs are received, bolts connecting't-he respective lugs in their slots, the slots being slightly wider} than the lugs, and means for imparting a longitudinal movement to the single connecting rod, as and for the purpose set forth.

In testimony whereof, I afli'X my signature in presence of two witnesses.
