To all whom it may Be a known that ons Am ti citizen of the portation -Cars and the Like, of which the following is a my invention I provide between the center sills or. draft sills of the car a pivotallymounted crank-frame connectedby links with the hinged gates and operate the same from 'atransverse'shaft located at one side of the gates and below onein'clined floor-section of the car, this shaft having on its outer end means whereby it may be rotated in either direction and at, its inner. end carrying a sprocket wheel which is connected by a, chain with a sprocket wheel secured upon said crank-frame, whereby motion may be communicated from the said operating shaft to the said crank frame for openin and closing.

the discharge gates.

. It is of advantage to locate the means for openings-rid closing the gates at a point removed from said gates and it also is advatangeousto locate the operating shaft for the gates transversely of the car and'belowthe floor 1 thereof.

' The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure. 1 is atop view, partly broken away, oi the middle portion of a gondola-type 'of car equipped with discharge gates and gate operating mechanism embodyin my invention; Fig. 2 is a longitudinal section of same on the dotted line 2-2 of Fig. "1; Fig. 3 is a transverse section of same, taken generally on the left hand dotted line 3- Fig. 2, but a portion of Fig. 3 being taken on the right hand'dotted line 33 of Fig.2 so asto disclose the operating shaft; Fig. 4 is a detached view of a bearing plate secured onthe side of the car to receive the outer end of the operating shaft and the means provided thereat for locking said shaft when the gates are in closed position; Fig. 5 isaside elevation on an enlarged scale of the crank-frame shown in Figs. 1, 2 and 3 as located between the center-sills of the car; Fig. 6 is a face view of same; Fig, 7 is an edge view of one of the links by which the crank frame is connected with. the gates; Fig. 8 is a side elevation of same; Fig. 9' is an enlarged sectional view corresponding with Fig. 2,

and 11 are face and side views respectively of a modi fled form of the'cra'nk-frame.

I illustrate in the accompanying drawings, my invention applied to a familiar type of car adapted for carryingcoal, coke and other substances, 20, 2O designating the sides of the car, 21, 21 downwardly converging or inclinedfioor sections leading to the dischargeopening in the bottom of the car, 22, 22 the hinged gates for said opening, 23 the center-sills of the car, 24- the usual covering for said sills, 25 a crankframemounted between said sills and above said gates, 26 links pivotally secured attheir upper ends to the upper end of said frame and at their lower ends .to eye-bolts 27. respectively fastened to said gates, 28 a transverse operating shaft extending from one side of the car below one inclined floor section 21 to the space between said center-sills, 29 a sprocket wheel on the inner end of said" shaft, 30 a sprocket wheel on said crank-frame, and 31 a chain connecting said sprocket wheels 29, '30 forimparting motion from said operating shaft to said crank-frame for opening-and closing said gates, the outer end of said operating shaft being pol onal in loutline (Fig. 4) to receive a wrench for actuating' it and being equipped with a ratchet wheel 32,

pawl 33 and locking dog 34 for locking said'shaft when the gates 22 are in closed position, said ratchet wheei v 32, pawl 33 and dog 34 being or familiar construction and illustrated in Letters Patent No. 301,459 granted October 10, 1905.- v

The operating shaft 28 is located to one side of the gates 22', where a person operating said shaftis not liable to become injured by the. gates during their opening movement nor by any material discharged from the car, and said shaft 28 extends transversely below the inclined floor section 21 where it is out of the way and does not interfere with the proper discharge of the material from the car. The inner end of the shaft 28 has a bearing in one of the center-sills, and the outer end of said shaft has a bearing in a plate 35 applied to the sides of the car.

The crank-frame 25 is preferably an integral casting formed with a back 36, sides 37, an aperture 38 at its upper end to receive a pin, and .trunnions 39 at oppo- ;site sides of its lower end to'be journaled in bearings 40 secured to the center-sills 23. The trun-.

nions 39 have polygonal sections 41 at theirinner ends upon one of which is'slipped the correspondingly shaped hub of the sprocket wheel 30. The aperture i 38 in the upper end of the frame 25 extends transversely through the sides 37 and receives the pin 42 upon which the two links 26 are hung, said links.(when the gates 22 are in closed position) being side by side be tween the sides'37 of said frame and bearing against the back 36.

of the pair of gates detach'edfmm the car; and Figs. 10

The links 26 are plain bars and they extend below the a ial'jcenter line of the trunnions 39 "and'are pivot"- ally secured to-theheads 43 on the eye-bolts 27, one of which is carried at th'e in'nier edge of-one gate 22- and the other at the inner edgeof theother gate 22, whereby onelink 26'becomesconneeted'with one of said gates and the other link w th 'the other of said gates.

The. gates 22 are hinged, at 44', at their outer edges, as usual, and comprise the nietal plates 45 hinge-straps 46, Z-bars 47, channel-bars 48' (Fig. 9) and bracebars "49. f The plate 45 of the right hand gate 22 laps over 'upon the Z-bar 47 of the left hand gate, and this bar closes the space between the inner edges ofthe gateplates 45, thereby preventing leakage between the inner edgesof the gates when the latter are in closed pdsition and the car is in' transit. "lhe' eye-bolts 27 extend through the inner 'portions of the gates-22, as-

inore clearly shown in Fig. 9, and the disposition or their head s 43 with respect to'the links 26 is such as to insure the right hand gate", looking at Fig. 9, closinga little in advance of the left hand gate, 'so that the edge of the Z-bar 47 of the left hand gate may lap under' the inner edge of the gate-plate 45 of the right handv gate. The complete overlapping of the inner edges of the gates I regard as an important feature, since the effectual closing of the joint between the inner edgesof the gates saves a loss of the substance carried by the car and which loss has heretofore been a matter -ofannoyance.

In Figs. 1, 2, 3, 4 and 9, the parts are shown in the relative positions they occupy when the gates 22 are in closed position, said gates being thenjlocked in closed position, first, by the locking of the operating shaft 28 by means of the ratchet.32, pawl 33' and dog 34, and, secondly, by the fact that the crank-frame 25 inclines to one side of a vertical line through thetrun nions 39 and that the lower ends of the links 26 are.

piv'oted ona center set off from the axial'center of said trunnions and that the pull on said links by the closed gates tends to further incline said crank-frame, whereby said gates'become effectually locked in closed p0sition. The inneredges of the links 26, when the gates 22 are in closed position,'ha've a bearing against the frame 25, which partly relieves the strain from the pin 42 and enhances the strength and efiicien'cy of the "structures.

To open the gates 22 the attendant will free the dog 34 irom the pawl 33 and said pawl from the ratchet wheel 32 and then turn the shaft 28 upwardly and toward the center of the car until, through the

sprocketwheels

29, 30 and chain 31,-the crank-frame 25 has been moved fromits inclined position shown to a simiposition at the other side of a vertical center line through the trunnions 39, at which time the weight of the gate's22 and thatlof' the load'iipon them will drive sa id gates to their full open position, the gates in this movement pulling the links 26 withthem and causing the crank-frame 25 to turn downward-1y. After the load has been discharged, the gates 22 will be closed by reversing the movement of the shaft 28 and thereby,

:through the sprocket wheels29, '30 and chain 3 1 grad- I 'ually restoring the crank-frame 25' to its ,upper position shown in Fig. 2, "said frame 25"during its upwardly turning movementpulling on the links 26 and drawing the gates 22 upward'lv to'tlieir closed position. one

gate slightlypreceding the other so that the overlapping ofth e meetin'g portions of the gates may be ef- ,i'ected, When the gateslfinally'reach their 'closed'position. the erank-framZ will incline to one side of a vertical; center line throughzthe trun'nions 39 and the links 26 will c0ntac't with and bear against a part of saidframe as a-stop and by their relation with said frame prevent the same froni folding over unduly in frame and links by passing beyond avertiCal center gates in their closed-position, and the gates may be further locked in closed position by the locking of the operating shaft 28 by means ofthe pawl 33 and dog 34. i In Figs. 10 and 11 I show a modifiedform of the crank-frame 25, this modification consisting mainly in substituting a central bar 50 for the three-sided frame bear; against recessed portions 51 of the. trunnion-sections 41, when the gates are in closed position, instead in Fig. 2. In'FigJ 10' the upper end of the bar 50. is shown as provided with studs 52 to receive the upper verticallydisposed and straight.
