" 1 Application filed June 23, 1903. serial No, 162,793- (No model.) i

T alZl whmn. it may concern: A Be it known that I, RICHARD MoBLEY, a citizen of the United States, residingat St. Louis,

.in the State of Missouri, have invented new and useful Improvements in Can-Doors, of

.which theifollowing is 'a specification.

This invention relates to car-doors, and particularly to that class of such doors known as flush doors, which seat in door-openings formed in the sides of the cars flush with the outer surface of the latter; and it has for its object to improve and simplify the construction and facilitate and render more efficient To these ends my invention consists in th and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description,- reference being had to the accompanying drawings, forming a part of this specification, wherein Figure 1 is a view in front elevation, showing the door seated in the door-opening and locked. Fig. 2 is a vertical sectional view taken on the line 2 2 of F ig. 1. Fig. 3 is a View in front elevation. showing the door raised and swung out from the door-opening. Fig. 4 is a vertical sectional View taken on the line 44 of Fig. 3. of the door-operating mechanism removed from "the car and door. Fig. 6 is a detail secview of a modification.

Referring to the drawings, the numeral 1 indicates the side of the car, and 2 a door-opening formed therein, the top and bottom or sill ofthe car being inwardly beveled, as shown at 3 and 4. v v v vThe numeral indicates thedoor which is beveled at top and bottom to correspond to door-opening and extending to one side thereof is a trough-shaped metallic track 6, and

fixed above said track is an inverted-troughshaped hood 7, provided with a depending Fig. 5 is a detail view flange 8, which overhangs 'the outer side of the track. Said hood serves to prevent rain, snow, dirt, and the like from gaining access to the track. Attached to the upper portion of the outer side of the door are two brackets 9, each being substantially U-shaped and provided at its upper ends with bearings 10, the lower end of each of the brackets being bent at right angles to forma flange 11, in which is formed an aperture 12; Passing loosely through eachof said apertures is the-lower ,end of a hanger 13, the upper end of which is bent into substantially inverted-U shape, as indicated at 14, to overhang the track 6. Journaled in the upper inVerted-U-shaped portion ofv the hangers are axles 15' on which are mounted wheels 16', that are adapted to travel on the track.- As before, stated, the lower ends of the hangers pass loosely through the apertures 12 in the brackets 9, and the lower extremities of said hangers are provided with laterally-projecting lugs 17, for apurpose hereinafter explained.

Journaled in the bearings 10 of the brackets is a rock-shaft 18, said rock-shaft between the two members of each bracket being bent to form a crank 19, said cranks being rotatably mounted in bearings 20, formed on or attached to the hangers. The rock-shaft 18 midway between its ends is bent to form a crank 21, said crank being set at a slight angle a relatively to the'cranks'li), before referred to.

Secured centrally to the upper portion of the door is a substantially U-shaped bracket 22, the two members of which are provided at their upper ends with bearings 23, which ernbrace -the rock-shaft on each side of the crank 21. Loosely attached to the central crank 21 is the upper end of a vertical rod 24, which intermediate its ends passes loosely througha guide25, attached. centrally, to the door. Attached centrally to the lower portion of the door isan oscillatory lever 26, said lever being pivoted midway between its ends on a pivot pin or stud 27 fixed to the door. The opposite ends of said lever are provided with laterally-projecting loops 26,form.- ing handholds, and a perforation 28 is formed in said lever eccentrically to or on one side of the fulcrum of the lever, and the lower IOO end of the rod 24 is bent at an angle, as at 29, and said angular portion is loosely fitted in said aperture.

Attached centrally to the door-sill beneath the door-opening is a bracket 30, provided at its upper end with a bearing or bearings 31 in which is rotatably mounted a rod 32, the end of which is bent at a right angle to form what 1 term a sealing-pin 33, said pin being provided with an aperture 34. One side.

of the bracket 30 is provided with a laterallyprojecting flange 35, provided with an aperture 36.

Fixed to the door-sill at each side of the door-opening is a bracket-lug 37, provided at its outer portion with a vertically-projecting flange 38, said bracket-lugs operating to prevent the door from swinging too far outwardly when the door is opened. When the door is closed tightly, the lower edge thereof drops behind the inner sides of the bracketlugs and holds the lower edge of the door tightly in place. A similar bracket-lug 39 is fixed to the exterior of the car to one side of the door-opening, and stop-lugs 40 and 41 are fixed to the side of the car to limit the lateral movement of the door in either direction.

The operation of my improved door is as follows: To close the door, it is moved along the track opposite the door-opening. Then by giving the lever 26 a slight turn, so as to oscillate the rock-shaft 18 sufliciently to throw the cranks 19 out of a vertical plane, the weight of the door will cause the latter to drop, and in dropping the cranks 19 are turned so as to cause them to throw the upper edge of the door to its seat in the door-opening. As the door lowers itself into place its lower edge drops behind the bracket-lugs 37, and the lower edge of the door is thereby firmly held in place. The upper edge of the door is held in place by the cranks 19, which as the door drops into place push the upper edge of the door to its seat. The door will now be held flush with the exterior surface of the car. As the door automatically drops to its seat in the door-opening the lever 26through the medium of the rod 24 and central crank 21 is turned to a vertical position, and one of the loops 26 is thereby caused to pass over the sealing-pin 33, the latter having first been turned to a vertical position. The sealingpin is then turned down vertically, so that its aperture 34 will be in alinement with the aperture 36 in the flange of the bracket 30, after which a wire may be run through said apertures and its ends secured by a lead seal in the usual manner, thus locking the door in place and preventing its being turned without defacing or destroying the seal. To open the door, the sealing-pin is turned up to a vertical position, and the operator then grasps the two loops 26 on the lever 26 and turns said lever to a horizontal position. As said lever so they will be rendered durable.

is turned to such position, the vertical rod 24 being connected eccentrically to said lever, said rod is turned downwardly, thereby d rawing down the central crank 21 of the rockshaft and turning the latter in its bearings, so as to throw the cranks 19 into a vertical position. As said cranks assume such vertical position they exert a lifting action on the door, raising the lower end of the door from behind the bracket-lugs 37 and at the same time raising the upper edge of the door and throwing it away from the door-opening. \Vhen the cranks 19 have assumed a perfectly vertical plane, the weight of the door will hold them in such position and will hold the door thrown outwardly away from the door-opening. The door may now he slid to one side of the door-opening upon its track entirely clear of said door-opening, and when in this position the weight of the door causes it to hang closely against the side of the car and prevents the door from moving, owing to the vibrations of the car. As before stated, the weight of the door assists in closing it and holding it shut and also holds it against movement or from jerking back and forth on the track when open, due to the motion of the car. The lower ends of the hangers 11 pass loosely through the apertures 12 in the brackets 9 and prevent the lower ends of the hangers and the door from swinging or moving away one from the other, and the lugs 17 on the lower ends of the hangers are provided for the purpose of catching the door and preventing it from dropping from place in case of breakage.

By means of the arrangement shown and described but slight force is necessary to operate the parts to raise the door from its seat in opening said door, and, as before stated, the weight of the door itself materially assists in causing the door to seat itself flush in the dooropening.

ln mounting the wheels 16 in the hangers 13 the axles 15, before referred to, preferably consist of bolts, which pass through the opposite sides of the hangers 14, as most clearly shown in Fig. 6 of the drawings. Arranged on the bolts 15 are sleeves 15, and the wheels 16 are rotatably mounted on said sleeves. After the parts have been assembled the bolts are tightly drawn up into place, contracting the sides of. the hangers 14 and causing them to clamp the sleeves between them, so that said sleeves will be held against rotation. The purpose of such an arrangement is to take the wear of the wheels from off the bolts or axles and to enable the parts to be cast very hard, If desired,

shoulders may be formed on the ends of the sleeves, which will impinge against the sides of the hangers and aid in preventing the sleeves from rotating.

In Fig. 7 I have illustrated a modified form of mechanism for operating the rod 24 and for locking and sealing theparts. Referring to said figure the numeral/t2 indicates the bail shaped lever provided centrally at its upper end with a crank portion 43. The rod 24; is 5 provided near its lower end with an eye 44, in which is loosely journaled the crank portion 43 of thelever, and the lower extremities of said rod are provided with a hook 45. numeral 46 indicates a plate having formed thereon a vertical cylinder-housing in which is movably fitted the bolt 47. Said housing is slotted on its opposite sides, as at 48, and formed on the upper end of the bolt are lateral projections 49, which pass through said slot, furnishing ready means for raising the bolt.

The upper end of the plate 4 6 is provided with a'loop50, and formed on said plate a slight distance below the housing is a perforated lug 51, the perforation in said lug being in aline.

mentwith the bolt. The lower end of. the

v said plate is perforated, as'at 52, and through vsaidiperforation extends a staple or U-shaped (bolt 53, on which is fixed 'awasherplate 5a. \Said'bolt or staple is fixed in the side of the .car centrally below the door-sill, as shown,

and holds the plate 46 in place. The lower hooked end of the rod 24 engages the loop formed on the upper-end of the plate. The operation of this portion of the device is as 3 follows: When the lever is raised into-an upright position, it lowers the rod 24 and rocks the shaft 18, "so as to open the door, and conversely, when said lever is turned down it presses the door to its seatand holds it se- 3-5 curely thereto.'--The lower end of the bailshaped-lever-when in its lowered'position rests between the housing and the perforated lug beneath the latter, and the bolt falls by gravity and its lower end passes through the 4 perforated lug, therebylocking the lever in: place. -The lower.end of the bolt is perfor.

rated, as shown, and-theparts may be readily sealed by passing a-wire through the perforartion in the lower end of the bolt and through r '45 'the staple and then securing'the. ends of the W wire together by lead seal in the usual wellknownma-nner; Theupper end of thebailshaped lever is journaled in clips 5,5,which areattached to the lower portion of the. door -5 on opposite sides of the crank portion of said lever.
