UNITED STATES PATENT Erica ROBERT (l. GREENERD, OF BOSTON, MASSACHUSETTS.
COAL-CONVEYER.
SPECIFICATION forming part of Letters Patent No. 584,112, dated June 8, 1897.
Application filed August 13, 1896 To @ZZ whom it may concern:
Be it known that I, ROBERT C. GREENERD, of Boston, in t-he county of Suffolk and State of Massachusetts, have invented an Improvement in Coal-Conveyers, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
My invention relates to improvements in devices for handling' coal, being particularly in tended for elevating coal from the` sheds direct-ly into the delivery-wagon.
lVith this end in view l have invented the hereinafter-described improvement, whereby the coal may be quickly1 raised, screened, and delivered into the wagon at any point in the coal-yard by means of a single stationary source of power. The mechanism is automatic in its operation and may be readily shifted longitudinally of the yard and transversely thereto in and out of the successive divisions or alleys of the shed.
My invention comprises various details of construction hereinafter set forth and includes improvements in the con veyer mechanism for enabling the latter rapidly to enter and convey the coal.
In the accompanying drawings, illustrative of the preferred form of my invention, Figure l is a side elevation, partly broken away,show ing the elevator plow or shoe and feeding mechanism and a portion of the general operating mechanism. Fig. 2 is an enlarged detail in perspective, showing the movable entering edge of the shoe. Fig. 3 is a view in perspective of a modified form of shoe and feeding mechanism. Fig. i is a side elevation of further modifications relating to the shoe and feeding mechanism. Fig. 5 is a side elevation, partly in section, showing my invention in operative position in a yard, the feeding mechanism being omitted for clearness. Fig. G is a top plan view thereof, and Fig. 7 is a plan view of the yard intended to illustrate the plan of operation of my system.
In the drawings, A designates a suitable framework or track-support which may coniprise the posts and beams of the coal-shed proper. This framework carries, preferably, two sets of tracks, which I will designa-te for Serial No. 602,651. (No model.)
convenience as cshed tracksL-an upper track A and lower track A2.
An elevator-carriage B is carried by the upper track and comprises suitable mechanism for operating the elevator C, this mechanism consisting in the present instance of a driveshaft b, having a centrally-mounted drivepulley b' thereon, and an elevator-shaft b2, carrying sprocket-wheels b3 at each end and driven by intermediate shafts b4, geared at one end by beveigears to the drive-shaft l) and at their other ends by worm-gearing to the elevator-shaft b2. The elevator in the present instance consists of a sprocket-chain c and buckets c', carried by side supports G', secured at their upper ends to the shaft b2 and carrying at their lower ends a shaft c2, provided with suitable sprocket-wheels ccorresponding to the upper sprockets h3. The outer end of the shaft c2 is provided with rollers c4 to run in the lower tracks A2, in order to give steadiness and the required strength for rapidly elevating the coal, braces C2 being provided, secured at one end to the support G and at the other end to the carriage B.
In order to facilitate the handling of the coal and insure the rapid and effectual filling of the buckets as they are revolved in the direc tion of the arrow, Fig. l., I have provided at the lower end of the elevator a plow or shoe D, preferably closed at its rear end and projecting forward at its front end, the sides thereof being preferably laterally bent somewhat, as indicated in Fig. 6, and the edges being deeply notched to provide coarse teeth d in order to gain easy access to the coal.
In order that the shoe maystill more readily work its way into the opposing heap of coal, I have made provision to laterally reciprocate the front edge of the bottom of the shoe.
In Figs. l and 2 I have made the edge of the shoe in the form of a plate d', movable in` guides d? by suitable means, as by a bellcrank d3, pivoted at (Z4 to an ear d5, projecting from the shoe D, and operated by means of a link d and eccentric-strap d7 on an eccentric ds, fixed to rotate on and with the shaft c2.
With thestyle of elevator and its buckets which I have herein selected to show in connection with my invention it is ordinarily IOO possible to use only a fourteen-inch bucket as a maximum, but by my improvements I make it possible to employ buckets of very much greater Width. To thisend I preferably provide a feeding mechanism D', shown in Fig. l as journaled in the sides of the shoe D and in Fig. 3 as journaled in asupporting frame or bracket D3, the latter having rollers (Z9 to run in the tracks A2.
The feeder consists, preferably, of a series of spirallyarranged blades or scoops d10, shown as rotated by a sprocket chain el, passing over sprocket-wheels on the feedershaft and lower elevator-shaf t c2. Any other suitable operating mechanism therefor may be provided. The edges of the blades d10 will preferably have coarse teeth.
As the shoe D Works its way into the coal the feeder D' enters with a sliding or shearing movement into the coal, loosening the bedded mass and scooping it up to be delivered into the buckets of the elevator. In the case of anthracite coal it is usually preferable for the feeder D to carry the coal over, as shown in Fig. 3, but in handling soft or bituminous coal and coal screenings itis preferable to operate the feeder in the reverse direction, as shown in Fig. et. In the latter case the blades d10 are slightly curved in an opposite direction to that shown in Fig. 3, and an upwardly-bent plate Del is provided, against and over which the feeder scrapes the so ft coal into the buckets cw, the latter in such case being sm aller and closer together than in the construction shown in Fig. As shown in Fig. 3, instead of having the edge merely of the bottom of the shoe reciprocate I have shown the bottom itself as reci procated, it bein g pivoted at its rear end on a post clwfor this purpose and having the bell-crank d3 mounted on a projecting arm Z13 of the frame D3. In this construction the stationary sides of the shoe D are omitted, and movable and preferably rotating sides D5, notched and preferably secured to the ends of the feeder D, are provided to enter the coal and hold the same in to be rapidly caught by the feeder. These rotating or independent sides may be used in connection with the stationary bottom shown in Figs. l and 2, if desired.
The elevator may be advanced into the coal with remarkable rapidity by means of the several mechanisms above described.
IVhen I speak herein of elevators, I desire it to be understood thatI in no sense restrict myself to the form of endless chain and b ucket herein shown, inasmuch as any other or desired conveyer may be used, and Whether it actually elevates or not and while I prefer to use together all the mechanisms described and to be described, yet it is to be understood that various details thereof may be used separately and with other mechanism.
The resistance offered by the compact mass or heap of coal is considerable, and therefore, in order to reduce the strain on the carriage and elevator to a minimum, I have provided a ratchet a on the lower track and a pawl d to cooperate therewith, in order that the frame or truck may receive the strains due to the tendency of the elevator to move back- Wardly when itis digging into the coal. Preferably also a dog d2 is provided on the carriage B to cooperate with the rack-bar d3 for the purpose of insuring steadiness of parts in the operation of the mechanism. The pawl d and dog a2 are operated by any suitable means, a common lever a4 and links a5 being shown for that purpose. The coal being elevated by the buckets c is delivered to a screen E, which is suspended in any suitable manner, as by means of the rods e, from the carriage B, and is preferably given an intermittent or jogging motion by means of the cam c', the screen being provided with slotted brackets e2 to maintain the same in proper relation to the cam-shaft and the latter beingl driven by a belt cgfrom the drive-shaftb. By this means as the coal falls on the screen E it is thoroughly graded and screened before it is delivered to the wagon, the screenedout debris falling, preferably, into a chute E', carried beneath the screen E.
In order to run the carriageB and elevator back and forth into different divisions of the shed, I have provided a cogwheel F on the underside of the carriage, gearing into the rack-bar a3, a chain or rope f being provided for the purpose of operating the gear F from the ground.
I-Iaving loaded a sufficient amount of coal from one portion of the shed, it is desired to shift the loading apparatus to another portion of the shed, and accordingly Ihave provided a portable track A3, mounted on rollers g at its outer end, arranged to travel in a track A4, running lengthwise of the yard. which I will designate as the yard-track. The yard-track is mounted in any convenient position, being herein shown as elevated, the post II, cross-tree h, and struts h being provided for the purpose; also, preferably, the portable tracks A3 will be braced at their outer ends by means of a brace d6 and strut al, the former having at its lower free end the roller d8, traveling on a suitable track, as h2, extending from post to post parallel to the track A". The yard-track, shed-tracks, and portable track will all preferably be U'-shaped, as shown in cross-section at the right of Fig. l, this style of track being preferable for the purpose of keeping out the dust and also absolutely preventing the wheels from j umping the track and also maintaining them in proper operative position notwithstanding any strain or tendency to tip from the track that may be brought upon them. Beneath the tracks A3, I provide a continuation of the rack-bar a3, in order that the carriage B may be readily run out on the portable tracks, as by hand. if desired, and locked thereon firmly in posit-ion by means of the dog a2. Stops a are provided in the tracks d3 in orderto limit the outward movement of the carriage.
IOR
YIR
The mechanism thus tar described is operated by any suitable power, a dynamo I being herein shown (see 7) for that purpose and the traction being transmitted by means of a Wire rope K. The latter' passes from the driving-drum I over aguide-pulley ll: at either end ot the yard, being directedv interinediately over the drive-pulley b by means ot guide-pulleys 7o mounted on and to move with the portable tracks A3. A takeup of any suitable form, herein shown as a Weight Il suspended from a pulley Z held in a loop of the driving-cable, is herein shown as provided at one end et the yard, in order to maintain the driving-cable under proper tension for driving friction on the drivingpulley l1', and also in order to take up the slack when the carriage B is moved ont and in on the shed-tracks, or is moved out on the portable tracks.
The portable tracks, with the carriage B moved out thereupon, may be moved longitudinally of the yard by any suitable means, but I prefer to use the driving-cable K for this purpose. To that end I have fixed on the drive-shalt Il of the elevatorl mechanism a toothed Wheel b5, Fig. 2,which may be locked against rotation when desi red by means of a movable bolt or dog ifi. When the carriage B has been movedout onto the portable tracks, the shaft 7) is held against rotation by engaging the dog Il with the `vlieel lf, and thereupon the further movement oi' the drivingcable K Will shift.- the portable tracks and elevater longitudinally on the yard-tracks.
I do not desire to be restricted in any Way to the mechanism herein shown for locking the driving-shaft against rotation, inasmuch as any other suitable means may be provided for holding the driving-cable against movement relatively to the carriage tor the purpose of shifting the latter by means of the cable back and forth along the yard-track.
In order that it may not be necessary to stop the driving-cable when. itis desired to stop the elevating mechanism, I have mounted the drive-pnlleyb loosely on its shaft and have arranged suitable clutch mechanism bl for engaging the same with its shaft Whenever desired.
The operation of my improved coal-handling mechanism is as follows: IVhen it is desired to load a Wagon with coal from the division l of the shed, the carriage is run into that division of the shed, as shown in Fig. 7, and is forcibly run into the coal heap and locked in position by means of the dogs ct e2, engaging the racks CL a3, as shown in Fig. l. The beveled or notched teeth of the shoe D enable the latter to be readily forced into the coal heap and likewise the notched edges of the buckets give ready access to the latter to the coal. The coal being elevated by the buckets is deposited on the screen E, which is agitated by means of the cam c2, thereby screening and grading the coal, the debris being deposited at one side by'means ot the lower end of the screen into the Wagon. Having loaded a Wagon, supposing it is desired to load the next Wagon from the coal in division 2 of the shed, the drive-pulley b' having been previously disengaged from driving relation With its shaft by means of the clutch b7 when it was desired to stop the elevator, the dogs a u? are disengaged from their racks and ordinarily the pull et the take-up L and ot the cable Will be sufficient to run out the carriage and elevator on to the portable tracks A3 Without further manipulation. However, the gear l?, operated by the rope f, maybe broughtinto service for this purpose, and the carriage B, having reached the stops a on the portable tracks, is locked into positionand the bolt b is engaged with the wheel b5 of the driveshaft, so as to positively hold the saine against rot-ation. rlhe driving-pulley h' is then engaged with the drive-shaft b and is likewise held against rotation by means of the bolt b5, so that the continued movement et the driving-cable K in the direction ot the arrow, Fig. l, serves to move the portable tracks and carriage along the yard-tracks A4 to the desired position opposite the division 2 of the shed. The clutch bi is then disengaged from the driving-pulley b and the carriage B is moved back into the division 2 by means of the gear F and hand-rope f, being secured in. place, as before, ,by means of the dogs of CL2, operated by the hand-lever ci.
Many changes and modifications in the details, arrangement, and combination of parts of my invention may be resorted to Without departing from the spirit and scope of in yinvcntion.
