OSCAR ILLI, 0F POCATELLO, IDAHO.

Idaho, have invented new and yuseful lin-. provements in' Door-Hangers, 'of which the following is a specification.` Y

This invention relates to improvements in therefor. A y

In carrying out the present invention, it is my purpose to provide a car door which may be moved to open and closed positions without the aid of rollers and guide tracks and analogous devices now generally in use.

To this end theinvention consists in the construction, combination and arrangement of parts hereinafter setforth in and falling within the `scope of the claims.

In the accompanying drawings:

Figure 1 is a fragmentaryside elevation of a car equipped with a door and lever mechanism constructed in accordance with car door hangersA and operating mechanisml my present invention, the lever mechanism being shown in dotted lines.

Fig. 2 is a diagrammatic view of the lever system.

Fig. 3 is an enlarged fragmentary hori zontal sectional view through the sections constituting the door.

Referring new to the drawings in detail, l designates one side wall of a car, such side wall being formed with a door openf ing 2. Suitably secured to the side platev of the car, above the side of the door opening are pivot bolts 3- and 4, spaced to obtain the desired movement of the door.

Suitably fastened to the side sill of the car,

below the edge of the door opening is a bracket 5 carrying pivot bolts 6 and 7 spaced to obtain the desired movement of the door.

8 designates the Vcar door and, in the present instance, this door comprises an inner metal section 9 andan outer metal section 10; and interposed between the sections 9` and 10 at the opposite edges of the door are vertical connecting bars 11 equipped with .inwardly projecting lugs 12, disposed along the bar and formed with openings aiming Vith openings in the sections of the door to 'eceive securing bolts or rivets 14, whereby he sections 9 and 10 may be held in spaced vformation and against relative movement.

'tion bulged or angular.' K equipped withlugs 16, formed with op'en- 'j 6o j Specication of Letters Patent.y Patented July il? llgll 7 Application filed January 8, 1916. Serial No. 71,045.y i i y i i Each connecting bar 11 carries a strip 15, having the end portions thereof fastened to the `connecting bar and the central por-` ings respectively al'iningwith openingsin thejsections 9 and' v1() ofthe door. .Through these alining4 openings are passed securingfbolts 18 coperating with the bolts 14 Said strips are to maintain the sections`9 and lOlin door' formation. In this instance, each metal sAec? tion 9 and 10 of the door is corrugated so as to strengthen the door. The respective `corners of the door may be protected by' means of shields 19 constructed' of metalV or any other material and secured to the sections 9 and 1F at `the corners, while fastened to the outer section of the door adjacent to the lower edge thereof and spacedhorizontally about as shown are reinforcing plates 20' carrying pivot bolts2l and 22 respectively. These pivot bolts 21 and 22 terminate short of the inner section 9 of the door in order to accommodate ythe levers 23 and 24 hereinafter described. Arranged between the sections 9 and 10 of the door are levers 23 and na no., ,y f

24 and the lower end of the lever 23 is mounted upon the bolt 21, while pivoted to `the upper vend of such lever 23 at 6 is the inner end of a linkv 25,l and the other end of the link 25 is pivoted upon the bolt 3. The lower end of the lever 24 is mounted upon lthe bolt 22, while the upper end thereof is` pivoted at 7 to the inner end of a link 25 and the remaining end of the link 25 is pivoted upon the bolt 4. Pivoted to the lever 23, at a point 23 thereof suitably located to' determine` the desired movementv of the door, is one end of a supporting bar or lever 26, while the remaining end of the lever 26 is pivoted vupon the bolt 6 carried by the bracket 5. Another supporting bar or lever 27 has one end pivoted to the lever 24,` at a point 24 of such lever 24 to suitably de- ,Y

and -he remaining end mounted upon the bolt 7 carriedby the bracket 5.

In practice, when the door is moved long1 'termine'the desired movement of the door, 100

tudinally of the adjacent side wall of the car to cover or uncover' the door opening, the,

lower ends of the levers 23 and 24 swing on and travel with the moving pivot bolts 21 and 22 respectively, while the lower ends of the bars 26 and 27 fulcrumed upon the sta- 22, these points having move ofthe door opening.

1d intermediate pivots. Referring now tothe* i diagramshown in'- Fig. 2', when the door moves to openlposition, the 'right hand angular strip ltravels away from the angle 7 24', @and the latter changesfrom are- 115. entrant angle tol a salient'angle as seenhin t 'is dptted lines yat the vextreme right of I view. `Meanwhile, the salient angle 6.,23, 6 changes to a rentrant angle, and assumes the same just at a time when the door reaches 20 'its eXtreme open position, se that the 'lefthand angular stri 15 -falls'A into' the angle 4and checks the furtlli the door. The latter during' v.its travel-has been sustained by'two vmo'vingdpivots 21'- and to tlieri llt along a horizontal line as shown in the 'aam. This iows from they fact that'the owei' .about t e same length as the bars26 and 27,

85l link.''construction at the top. The vinner 'pivots 6", 7 of the links are normally spaced aboutl the same distance as :the stationary. 6 and 7 on the bracket 5, and both pivots pairs stand coincident lwith the inner edge )It follows from this-disposition of .the 'lever iiiechanism that inv either open or I closed position one rentrant angle-rests against an angleA strip 15, and therefore stops tol prevent further movements ofthe door are not necessary when this imprpved formof hanger is employed, although I may y use them if desired and have shown 'them in the drawings.,` As all lever mechanism is arrangedbetween the Tsections 9` and 10- f the door'excepting the 'lower ends 'of the i' bars, it is thoroughly protected from the weather on the exterior and from freight on ,thgjnterion Secured to the outer side wall of the car adjacent vto the edge of the door opening remote from thelevers is -a vertical abutin ent or weather strip 28, having the edge thereof adjacent to the door opening formed with an oilset lip 29, while secured to. the

adjacent edge of the door is a weather strip 30,- formed with lips. 31 ada )ted to engagne;l under the lip 29. Secure tothe side of theic'ar adjacent to thevother edge of '.51 the-door opening'is a metal strip 32 having er 4opening movement of sides, in no way', bind the door.

Iprtion ofthe leviers 23 and 24 is ofV such action beingpermitted by the' the edge thereof remote from the door opening formed with an outwardly offset li 33, while fastened to the adjacent edge o the door is a strip 34 having the outer edge .thereof formed with inturned lips 35 adapted to engage'beneath the lip 33.'l These various strips and lips coact with one another to vheld 'the door 'against outward movement under the weight of the material in the car and, form tight connections lbetween the side edges-of thedoor and the wall of the car as a weather protection.

' 36 indicates a shield or protector that is bolted or otherwise secured to the side of the' car. adjacent to the roof and overhangs the path of movement of the upper edge of the door and its. associated parts from the elements.

It will be seen that I have provided a car door which is strong and durable in construction -and which will withstand rough usage, while the lever mechanism insures easy operation of the door at all times, as the sagging of the car or the bulgin` of the urthermore, it will be noted that this lever mechaany style of'door.
