Application illed April 6,1907. Serial No. 366,677.
lclear, and enact description.
. This invention has in view the provision of an improved dumping car oi the coal car type, in which the mechanism employed in operating the drop doors at the bottom of the car will be separated and protected from the coalor other material with which the car may be loaded, and thus prevent any interference with the operation of this mechanism from this source.
The invention further contemplates the employvment -oi the means for operating the drop doors,j
whereby the doors maybe readily released and speedily closed with an equal pull on each door, and the doors when dropped, will be carried clear oi the opening at the bettom oi the hopper.
' Reference is to be had to the accompanying drawings forming a part o'this speciiication, in which similar characters oi reference indicate corresponding parts in all the igures.
Figure l is a central, through a dumping car embodying my invention; Fig. 2 is a plan ot the same; Fig. 3 is a view of the winding-mechanism or drawing up andreleasing the doors; Fig. 4 is a section on the line 4-4 of Fig. 3, lookingin the direction oi the arrows; Fig. 5. is a sectional view showing the arrangement o'the sheaves andsupporting means therefor as are positioned above the doors of each hopper; Fig. 6 is a section on the line G-6 o Fig. 5 looking in the direction of the arrows, and Fig. 7 is a face view of themeans employed in operating and locking the doors in place.
As shown in Figs. l and 2, the preferred construction of the car comprises two independentload-carryingY compartments each being provided with a hopper bottom 1 discharging through openings at each side of the center oa car, each or' said openings being closed by two drop doors 2, These doors are so hinged, as shown in Fig. l, that when dropped to a vertical position they will swing out oi the path of their respective discharge openings and `will thus not impede the discharge of the load when the car is dumped." .Each of the independent compartments of the 4car are themselves divided into two compartments by verti- 'cal walls 3 arranged at each side o the longitudinal center "of the car. rhe space between the.. Walls is utilized'ior the mechanism employed in operating the doors '2, this mechanism being thus separated and pro-l tected from the :coal or other material with which the car 'might be 16g-tasa. The said mechanism ismaeicarrying near their circumference a pin 6a longitudinal, sectional viewdoors and consists ofv crossv :1 shaits4-journaled suitablebearings at each. side of the center oi the car, preierabl'y close together in order that they maybe conveniently operated. Fixed to each shaft between the wallsf are spaced flanges 5 of substantially semicircular form, each pair o flanges on vwhich is journaled a grooved roller G.` 'Diametrically oppofA -site the roller 6 and also at one side thereoi, grooved rollers or sheaves 7 are journaled between the flanges,
'on axes or pins 8` the rollers 7 on each pin`8 being arranged side by side and of about one-half the width of the roller 6.
' Above each set oi drop doors 2 and at substantially the same eievation as the shafts e1, a pin or axis 9 is fixed at opposite ends in brackets' or blocks l0, the latter, as best shown in Fig. 5, being bolted or otherwise secured to the side walls 3. Between these blocks'are jourv naled on the pin 9, grooved rollers or sheaves 11, over which pass the oppositeends of a chain or other flexible line l2 leading from the roller 6 of Vthe winding mechanism about which it is looped. The free ends oi the chains 12 are each attached to one ofthe drop doors 2 near its free edge, engagement of the chain with'the i rollers 11 being insured by lf onstructing the blocks 10 with ribs 10 which are located on the top aces of the blocks and slope from the walls 3 to the rollers 11. When'the winding mechanism is operated for drawing up the doors, the construction and arrangement thereof obviously admits oi the' ends o the chainrnoving with respect to each other over` the rollers, whereby the l:force expended in drawing the doors to closed position will be equalized At one side oi the car the'snaits 4 are slightly ex? tended and formed with angular wrench-engaging portions 13, and have fixed to them adjacent thereto ratchet-wheels 14. Each ratchet-wheel is engaged by a pawl 15 constructed with an angular wrench-engaging portion 1,6 by which it may be revolved. The pawl y l5 is locked in 4engaging position by a cam 17 the cam being likewise vconstructed with a wrench-'engaging portion 18. Allo the wrench-engaging,portions 13, 16 and 18 are preferably oi the same orin and size in order that all o'i them may he operated: by a single dey vice.
When the car is loaded, the position oi the'ratchetwheel 14, pawl 15 and 4cam 17 are as illustrated in Fig.- 7, in which position the drop-dors are securely locked in place. AWhen the car is to be dumped it is only necessary to disengage the carn 17 from the pawl 15 and `throw. the pawl to an elevated position.
` .It is evident that various immaterial changes may he made in the construction from that shown and hereinbeore described, and l consider that I am entitled to such modiications as fall veithin .the scope o the an- -nexe'dclaims l z Having thus described my invention I claim 'as newA and desire to secure by LetteirsPatent': n
