GRAIN -GA-R DOOR.

Toallwhom it may concern;-

:Be it lrnowmthat'fl, NERI'TERRY, acitizen -of Canada, a residentpf Hardisty, in the Province of Alberta, l Canada, have invented .a new and Improved GraimCar Door, of which the following I is a Ffllll, clear, and exact description.

rial against the Myinventionwrelatesito freight cars gen :erally termed :grain cars, although .useful ifor carrying'other loose material. a An object 'of 'the invention is to "provide :an improved; grain door. or auxiliary door at the iinsideofithe main door so constructed and arranged as to provide :for the readyarelease ofjthe "lower L section of the :door, not .withstandingrthe pressure of-the loose .matedoor. A :further object of the :invention vis'to provide (a 'grain -door of the class :referred to that may be moved to a position beneath the roof of 13118 0211:WliGIlrIlOt'iIl=US6,\tl1eK1001 :and its appurtenances being so :auranged that no elements*will projeet atitheitloorway ito offer :obstruction or interference when tthe-carzisunloaded. T i i y The invention :will the particularly explained in the specific description following. 7

Reference is to be had to the accompanying drawings forming a part "of-ithis specification in Which-similar reference :characters indicate corresponding parts in all the views,

Figure 1 is a fragmentary side Viewof a freight car showing my improved grain door in the lowered position at the door opening;

Fig. 2 is a longitudinal vertical section on the line 22, Fig. 3;

Fig. .3.is a transverse vertical section;

Fig. 4 is a detail front view showing a portion of my improved grain door;

Fig. 5 is a detail in horizontal section on the line 55, Fig. 8.

The invention is applicable to any ordinary box car 10 having a door opening, or openings, 11, and equipped with any ordinary car door 12, here shown as provided with hangers 13 traveling on a top rail 14: and with rollers 15 at the bottom traveling on a rail 16,

The improved grain door is designated generally by the numeral 17 and the lower section 18 thereof is hinged at its upper edge to the upper section by hinges 19, which Specification of Letters Patent.

aslats 20 "connected by hinges 21 ward direction, "'that is :to say,

.said iguides 2-1 overlapping Patented Feb, is, tiers,

at thezleft of Fig. 3.

The door 17 is "flexible being formed of disposed at "the inside of .the door tofbreak in an outin the opposite direction from the hinge :19 connecting the sections. The 'flexibility thus produced lllr'tile door permits of the saine being run in guide-waysQElon thercar at each side ofthe door opening :11. The said guide-ways 23 curve at itheir upper 1 ends and .coinmunicate with guides 24: beneath the car roof:22, the and being dis-- posed one above another so that the re spective door openings 11 at opposite sides will ibe arranged one above another Ebeneath the roof. The :guides are formed of suitable inner and outer irons 26, 26

.At the :lower ends the guide-waysi23 are i contractedaas at '27 byextendingitheiirons,

26, 26%1toward eaohother, thereby produc- :ing arestrictedWhroat-QS of'a sizexto permit the passage therethrough of the slatsi20 of the lower door "section 518. Theiinwardly projecting :members 27, however, constitute a stop :and :rest for :IHQIHbGlS 29 preferably in the form of rollers, which are provided on the sides -of the door *1? adjacent to the hinges 19. The arrangement is such that the rollers 29 will be arrested when the hinges 19 are below the throats 28 and thereby permitting the doors to swing outwardly. At the same time, the doors are retained in the guide-ways and prevented from running downwardly through the throats 28.

Below the guides 23, I provide displaceable retainers 30 for the lower door sections, these being in the form of plates, which are displaceable in their own planes in slots or openings formed in the car at the door opening, the said retainers being illustrated as moving between the studding 31 and the facing 32 in Fig. 5. The plates 30 are provided with transverse slots 33, through which pins or bolts 34 pass. Each retaining plate 30 has an arm 35 thereon which also preferably is slotted as at 36, the slots receiving pins or bolts 37 To operate the retaining plates 30, each arm 35 of the plates 30 at the sides of the doorway 11 is connected with a bellcrank lever 38, fulcrumed as at 39 on the car, and these bellcranks have connections with an operating lever. In the illustrated example, a link 40 extends from one bellcrank leverv38 to one arm of a T-shaped operating lever 41, i'ulcrumed as at 42 on the car at the inside or the outside according to the build of the car, the other arm of which lever is connected by a short link 43, with a bellcrank lever 44 fulcrumed as at 45 on the inside of the car beneath the roof. A bellcrank lever 46, similar to the lever 44', isprovided at the opposite side of the door and fulcrumed as at 47, said bellcranks 44 and 46 being connected by a rod 48 extending above the doorway. 11, and the lever 45 is connected with the adjacent bellcrank 38 by a link 49. Thus, the operating-lever 41, it'will be seen, is simply interposed in the link connections between one of the levers 38 and the adjacent upper bellcrank lever 44, while the opposite upper bellcrank 46 is directly connected with its bellcrank 38. The rocking of the lever 41 serves thus to withdraw both retainers 30 when it is dedesired to discharge the grain by permitting the lower door section 18 to swing outwardly.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:

1. The combination of a freight car having a door opening, members on the car at each side of the door opening forming guideways extending upwardly beneath the roof of the car, a door movable in said guideways, said door'being composed of upper and lower sections, the lower section being hinged to the upper section to swing out- Copies of this patent may be obtained for five cents each, by addressing Washington, D. 6.

wardly, the members forming the guideways constituting stops at thelower ends of said guide-ways, and the said guid'e-waysat the-said stops being in the form of restricted throats, said throats being positioned adjacent to the position of the hinge connection between the door sections whenthe door is in the lowered position, members on the door adapted to engage and be arrested by said stops, displaceable door retainers on the doOr at each side of the doorway below the said guide-ways, and means to displace said retainers to permit the lower door sec- 7 tion to swing on its hinges. v

2. ,The combination with having a dooropeningand guide ways at the sides of said opening at the interior of the car and extending upwardly beneath the car roof, of a door movable in said guides a freight car and composed of upper and lower sections,

the lower sections being hinged to the upper section to swingoutwardly through the door opening when the door is in the opened position, co-actingmeans on the door and in said guide ways to arrest the downward movement of the door when said door is in position for the lower section to swing outwardly, and displaceable retainers on the car at the sides of the door opening below the guideways and-complementary thereto to guide the lower door section. and prevent movement thereof on its hinges until the said retainers are displaced- In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NERI TERRY.
