CAR-DOOR-OPERATING DEVIGIP` Specification of Letters Patent.

` Patented July 9, 191e.

Application tiled January 18, 1911. Serial No. 603,374.

T0 all t may concern:

Be it known that I, LnvrN Gnssronn .Y HANDY, residing at Rutherford, Bergen is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

said drawings: Figure 1 is a longitudinal sectional view of a portion of a car illustrating my invention applied thereto, said section being taken approximately on line 11 of Fig. 2. Fig. 2 is a transverse sectional View through a portion o.c a car, said section being taken on the plane indicated by line 22 of Fig. 1, and looking in the direction of the arrow. Fig. 3 is a detail view of the crank-arm.

This invention relates to mechanism for closingthe doors of hopper bottom cars.

The object of the invention is to provide mechanism which will furnish positive locking means for said doors when in their closed position without the4 use of the customary pawl and ratchet mechanism.

A `:further object is to provide an increasing leverage upon the locking arm of the mechanism as t-he door is swung to its final closed position. v

A further object is to provide, in combination with the above, means for maintaining the door practically rigid in its fully open position.

jecting link-arm 6. At its free end said link-arm carries a wrist-pin 7.

Journaled in a suitable bearing as 8 formed 1n one of the brackets 4 and extending to one adjacent side of the oar, `or entirely across the car if desired, is an operating shaft 9. A journal bearin llOis fixed to the under sideof one or eac ',ofithe adjacent side girders for supporting the outer end or ends 0f said shaft.

The shaft 9 extends through and is supported in the bearing 8 and. carries a radial lever, or crank-arm 12, which armA is slotted as at 13. The wrist-pin Tprojects into said slot and has free ,sliding movement therein. A suitable head as 14 is formed upon the end of the wrist-pin, outside the slot 13, to prevent disclocatlon of the parts.

The. door actuating link 15 is pivotally connected, as at l15", to the lower or free -edges of the doors 16, it being understood that there vis a door 16 foreach of the` hopper chutes 3 and that the Said doors are pivoted along their-upper edges as at 17,

yas 1s common in the art.

The operating shaft 9 is spaced slightly `below and somewhat to the right of the `shaft 5, Fig. 1.

Thefslot 13 in said crankarm is arranged practically radial with the shaft 9, but is preferably disposed so that a lineA along the center thereof will pass slightly to one side of the said shaft 9, so

variable relative movement of the wrist-pin as to the crank-arm. As the crank-arm 12 is swung t0 Close the door, the wrist-pin 7 will move gradually toward the inner end ofthe slot 13 and nearer the shaft 9, thus gradually increasing the available leverage of the crank-arm upon the wrist-pin until the maximum leverage is reached when the doors are fully closed and the door operating link is in engagement with the upper surface of the shaft 5.

A pocket as 13 is formed at the extreme inner end of the slot 13 and is adapted to engage the wrist-pin after said wrist-pin has reached its final forward or locked position and thus retaining the wrist-pin against possible return. It will be noted that the outertherefrom through the center of the shaft 9,`

is preferablyl arranged at a slight incline relative to said line as is gapliieally illustrated in Fig. 3 ot the drawings, and that. thus Said Wall will readil)v disengage. itself from the wrist-pin when the operating sliatt is rotated for opening the doors. 'When the wrist-pin is in the pocket 13, as illustrated in Fig. 1. said wall serves to prevent moreinent. ot the wrist-pin and hence of the doors. the entire dead weight ot' the tree end of the Crank-arm heing` disposed to maintain the ei'igageiiieiit. lVitli the wrist-pin thusl positively held against movement all neeessity for the eiistoinaiw' pawl and ratchet mechanism oliviated.

irissiiining the parts to he in the position shown hy iiill lines iii Fig. l. The renter of the wrisi-pin T is in aiineinent with thel center otI the sha l't and the pivot pin l. or i'ireteral'ily slightly helow `said alinenient` so that the door is positively loeked in its closed position. rl`he severe jolting to whieh the parts are suijeet. in use would. liowiwer, were it'iiot tor the engageineizi otl the wrist- Vpin with the outer wall of the poeket lil, Cause the rear end ot the door aetiiating link 15 and the link-arm (3 to rise and so permit the door to open. The engagement ot the wrist-pin within the poeket 13 positively prevents movement ol' the wrist-pin and tliiis obviously no further retaining means is required. As the operating shaft is rotated and. the erank-arm swung tor opening the door. the Qoeket- 121, will lii'st he lit'ted trom .its engagement with the wrist-pin and said wrist-pin will he tree to travel along the Slot lil, As the operating' sliat't is further tlirned, the wrist-pin will more townard the outer end ot said slot and` finally, as the parts reach the position illustrated hy the heavy dotted lines, the liody ot' the ei'ankA arni strikes the shalt 5 so that l'nitliei' rotation of said crank-arm pi'ewnted. and the free end ofthe door actuating link t5 is supported iii such manner as to maintain the, door piartieally rigid.

ln closing and locking the door the shaft.- f) is rotated in a reverse direction and diii'- ingv this rotation the piii 7 will more toward the inner end of the slot'.y thatI is, toward the operatii'igshaft or Center oli torre, thus gradually inereasing the degree of leverage upon the door actuating link. lt .should be noted in this eonneetion that. the link-arm t' at this time. aside troni itsl 'imetioii ot' transmitting the \i eight olt the doors to the shaft` i?. sem-er; to guide the wristpiii 7 and the t'ree end ot' the door artuating link ronrentiieally around the shaft Tand eonseduently.

owing to the relative positions oeeiipied h V the shafts 7, and fi. the wrist-pin` is moved along the slot lf as' the operating|- slial't, is rotated. rl`lie hanger liraekets Vl Y twilli the iipwaidlj,v t'xtending angular llanges l2L may eomprise integral raslings. earli eoniierted as: ari` the meint-,ers vl-Y-l herewith shown.
