GRAIN-DOOR FOR FREIGHT-CARS.

Specification of Letters Patent.

Patented March 31, 190s.

pplication led December 31, 1906. Serial No. 360,311.

To all whom fit may concern.' Be it known that I, JOHN B. SMILEY, a citizen of the United States, residing at South Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Grain- Doors for Freight-Cars, of which the followin is a specification.

his invention relates to grain doors for freight cars, having for its object the provision of a door which will form a close grain tight joint or union with the door posts or .jambs of the car to eHectually revent any eaka e of grain in transit; and) further to provi e the door proper'with an auxiliary or relief door which 1s possessed of an outwardly swinging movement to permit a suitable amount of grain to escape to thereby relieve in part the ressure against the door, enabling the grain oor to be completely opened with ease and the ain to escape.

With the a ove andother objects in view my invention further consists in the novel details of construction and combination of parts to be fully described in the following s ecification and then pointed out in the c aims.

Referring to the accompanying drawings Vforming a part of this specification, wherein like characters of reference denote similar parts throu hout the several views z-Figure 1 is a side e evation of a freight car showing my invention applied thereto, Fig. 2, is a longitudinal section on line 2-2, of Fig. 1, Fi 3 is a vertical section on line 3-3 of Fig. 1, gFig. 4, is a front view showing the grain door detached and in side elevation, Fig. 5 is a similar view of the rear of the grain door, Fig. 6, is a vertical section on line 6-6 of Fig. 5, Fig. 7, is a erspective view of the W- shaped bars carrie by the grain door proper, Fig. 8, is a similar view of the angular hood secured to the door pro er at the top of the relief door opening, an Fig. 9, is a similar view of the angle iron which spans the lower side of the relief door opening.

1, denotes the door osts or jambs with which the joint is formed with-the grain door pro er, 2.

e grain door proper is composed lof a plurality of horizontal pieces 3 and verticalraces 4, suitably secured 'thereto the vertical edges at each end of the door having the W-shaped bars 5, secured thereto so that the inner portions 6, of said bars 5, will abut the door posts 1, and thereby not only restrict the outward movement of the door 2, but further prevent such door being nailed to the posts 1. By inspection of Fig. 2 it will be observed that bars 5 closely engage the sides as well as inner ends of door posts 1, thereby forming a close union between the two, which effectually prevents the escape of grain. It will further be noted that bars 5, embrace end braces 4 and thus not only add to the strength of the door` at these points but also protect such braces against wear and tear in removal and setting of the door from and into closed position. The door 2, is formed with a rectangular opening 7, which is adjacent the lower end thereof and extends through the lower end, in which the relief door is received, the lower side of which y is spanned by angle iron 8, which thereby forms the fourth side of the openin 7, the base of said angle iron being secure to the lower edgeof door 2, and the web of which engages the braces 4 and bars 5, the latter being cut away as indicated at 9, to receive angle irons 8. vThus angle iron 8 not only strengthens the ydoor 2, at its bottom and protects the same in use, but it further by virtue of its upwardly'pro'ecting web rovides an abutment or stop or the. relief oor 10 which limits the outward movement thereof. l

11 denotes an angular hood which is secured to the door 2, at the top of the relief opening thereof, this hood having an inner -f downwardly extending portion 12, which engages the inner face of relief door 10, intermediate portion 13, and outer upwardly extending )ortion 14, which is secured to braces 4 on eac side of the opening 7.

By reference to Figs. 1 and 2 it will be noted that braces 4, are cut away at their Vlower portions so as to have their vertical edges adjacent opening 7, disposed to the rear of the pieces 3, of door 2, to thereby form shoulders 15, against which relief door 10 may abut. .Relief door 10, is formed of two members the outer one 16 of which is of less width than the inner one 17, which thereby provides for the reception of shoulders 15 and enables close engagement therewith, as will be manifest from Fig. 2.

Each side of the relief door opening 7, is skirted by vertical bars 18 which at their lower portions are secured to braces 4, as shown in Fig. 5, and at their upper portions are offset as indicated at 19, to provide spaces 20, in conjunction with the exposed faces of bars 4, as shown clearly in Fig. 6, the offset portions 19 being secured to vertical portion 14 of the anglar hood 11, thereby not only providing a rigid structure, but further protecting braces 4 in use. Member 17 of the relief door receives on its outer face and at its upper edge a hinge bar 21, which is rigidly secured thereto, the extremities of this hinge bar being reduced as indicated at 22, Fig. 1, and being received in spaces 20. It will thus be obvious that relief door 10 may be moved vertically in spaces 20, and also swung outwardly at its lower end.

The member 17 of the relief door 10, is further strengthened by a vertical bar of metal 23, secured thereto, the lower end ofl which is turned outwardly as at 24, to provide a hand hold in raising door 10, vertically, the upper end of bar 23 being engaged by a gravity tongue 24 which is pivoted to member 14, of hood 11, and which frictionally engages the upper edge of bar 23, and thereby normally prevents upward movement of relief door 10. By inspection of Fig. 3 of the drawings it will be observed that the relief door 10, is capable of sufficient vertical movement to enable the same to clear the vertical portion of angle iron 8, at the inception of` its outward swinging movement.

Each of bars 5, is provided with an opening 25, which receives hooks 26, on brackets stationarily supported at .the upper end of the car to secure the grain door in position when out of use.

' The operation of the relief door is manifest from the preceding description. Tongue 24', bein moved free of engagement with bar 23, t e relief door is first raised, conveniently by use of hand grip 24, sufficiently to clear the lower edge thereof, of the upwardly projecting web of'angle iron 8, when th'e same may be swung outwardly by virtue of hinge bar 21.

Having thus fully described my invention, what I claim as new and desire to secureby Letters Patent, is:-

1. A grain door formed with a relief door opening, an angular hood secured to the door at the top of such opening having, upwardly and downwardly, extending portions on opposite faces of said door, vertical bars secured to the outer face of the door and having offset upper ends secured to the upwardly extending portion of said hood, a relief door in said opening engaging the downwardly extending portion of the hood, and a hinge bar on said relief door engaging said offset ends of said vertical bars.
