CAR-DOOR.
SPECIFICATION forming part of Letters Patent No. 554,932, dated February 18, 1896.
Application filed Augu t 12,1895- Serial No. 559,056. (No model.)
To (LZZ whom it may concern.-
Be it known that I, HEINRICH WILHELM FRIEDRICH JAEGER, of Sandusky, in the county of Erie'and State of Ohio, have invented a new and Improved Oar-Door, of which the following is a full, clear, and exact description.
The object of this invention is to provide a car-door which will be more durable and simple in construction than others heretofore produced and also which will ride more easily on its bearings.
To this end the invention consists in various combinations of parts and features of construction, which will be fully described here inafter, and finally embodied in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 represents a side elevation of a portion of a freight-car equipped with my improvements. Fig. 2 is a similar view showing the parts in a different position. Fig. 3 is a vertical longitudinal section of the car, showing an interior view of the door. Fig.4 is a horizontal. section on the line 4 4 of Fig. 3. Fig. 5 is a vertical section on the line 5 5 of Fig. 3. Fig. 6 is a fragmentary view showing the rollers or casters for mounting the door. Fig. 7 is a sectional view of the same parts, taken on the line 7 7 of Fig. 6; and Fig. 8 is also a sectional view of these parts on the line 8 8 of Fig. 7.
The car-body 1 is provided with the usual opening having the posts 2 at either side thereof, and these posts have the sides of the car secured to them and are braced by outwardly-extending braces 3. Lying alongside the inner sides of the car are the beams 4 and 5, the beam 4 being provided with a vertical dovetail 6, which is locked with the adjacent post 2, and the beams 5 being provided with a horizontal dovetail 7, the same being also locked with the adjacent post.
Pivotally mounted on a pin 8 is a grain-door 9, the same being arranged to fit in grooves 10, formed in the respective posts 2, and these grooves are aligned with the groove 11, formed in the beams 4 at the right of the door and in the adjacent brace 3. This groove 11 is pro vided to receive the door 9 when the same is open, as shown in dotted lines in Fig. 3.
Fixed to the inner side of the car is a chain 12, provided with a hook 13, and this is adapted to engage with an opening 14, formed in the grain-door 9, whereby the same may be held in an open position, as shown in dotted lines in Fig. 3. The upper right-hand corner of the grain-door is provided with an opening 15, (see dotted lines in Fig. 3,) through which a pin 16 is adapted to pass, whereby the graindoor may be locked in a closed position, and this pin 16 is provided with a chain, the same being secured to the outer side of the car and serving to prevent the loss of the pin.
The door 9 fits snugly within its respective grooves 10, as will be understood, to prevent the escape of grain which may be carried in the car, and the door-frame is provided at the bottom of the door-opening with a tread 17 the same being securely seated upon the floor of the car and formed with a groove receiving the lower edge of the grain-door, which construction serves to further tighten the connection of the door with the other parts of the car.
The outer or door proper of the car comprises a suitable body structure 18, provided at its inner side with a roller 19, which projects beyond the inner side of the door and which is held in a frame 20. This roller is adapted to travel along a wear-plate 21, secured to the outer side of the car, and by means of the roller 19 and the plate 21 the friction which would otherwise exist between the body of the car and the door 18 is overcome. The outward movement of the door is limited by means of the stop 22, which is secured to the side of the car, as best shown in Figs, 1 and 2.
Supported at the lower edge of the dooropening in the sides of the car and extending beyond the left-hand side of said opening is a foot-track 23, the same being held in place by means of brackets 24 secured to the side of the car, and this foot-track 23 is provided with a vertical flange at its outer edge and has the rollers or casters 25 of the door 18 mounted thereon. These rollers or casters 25 are carried in housings 26, each of the same comprising two parts a and b, the parts a being provided with a horizontally-extending plate 0, which passes through the upper part of a recess formed in the bottom of the car-door, and which is projected through an opening cl formed in the section 1), bolts 27 being provided and passed through the two sections and through the door,by which means the said sections are held in place. The rollers or casters are preferably two in numher, and are, together with their respective housings 26, duplicates in construction.
Located above the doonopening is the headtrack 28, which is rigidly secured in place and which is provided with a downwardly-extending outer flange. This track 28 has the rollers or casters 29 engaged therewith, and the said rollers are each mounted in a U-shaped housing 30, each of which is provided with a bow-spring 31, located and secured to its under side, and the said bow-sprin g 31 is in turn engaged with a second housing 30, which receives the housing 26 and the greater portion of the roller or caster, and this housing is formed with vertical slots 33, one in each side, which slots receive the trunnions 34 of the rollers or casters. The housings 32 are each rigidly secured in recesses formed in the upper edge of the body portion of the door, and by means of the springs 31 the respective housings are yieldingly mounted in the larger housings, so that the rollers or casters will be spring-pressed against the track 28. The housings 32 are similar in construction to the housings 26 above described, and comprise two sections 0 and f bolted one on each side of the door, the section 6 having a horizontal or transverse plate 9, which projects into an opening h formed in the other section. By these means it will be seen that the door 18 is mounted so as to be capable of sliding laterally alongside of the car, and that this sliding movement may be eitected without the presence of more than a nominal degree of friction. It will also be seen that the springs 31 will press the respective rollers or casters 29 into yielding engagement with the track 28 and by these means all jarring and rattling of all movable parts are prevented and the life of said parts is lengthened.
The right-hand post 2 is extended outwardly beyond the side of the car and provided with vertically-aligned eyes 34-, between which the hasp 35 is pivotally mounted, and this hasp swings 011 a vertical axis and is provided with a slot 36, receiving the keeper 37 of the wearplate 38, and also with an inwardly-projecting lip 39, which is received in a corresponding depression of the said wear-plate 38. The wear-plate 88 is rigidly secured to the side of the car-door 18 and provided with a swinging lock-pin 41, the same being curved so as to pass through the eye 37 and to lock the hasp 35 in place. By these means the door 18 may be secured in a closed position. Through the medium of the projecting lip 39 and the recess 40 the hasp 35 and the plate 38 are more securely connected, and the eye 37 is relieved of strain which would otherwise be imposed thereon.
From the foregoing description it will be seen that I have provided a door which may be operated without more than nominal physical exertion on the part of the operator, and that this is due to the reduction of the friction between the parts, and it will also be seen that owing to the peculiar construction of the rollers or casters loose movement or play of the movable parts is prevented and their life consequently lengthened. The operation of the door is similar to that of other car-doors and needs no special description.
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination with a car having an opening in the side thereof, of a door, tracks mounted above and below the opening, a roller at one edge of the door and engaging one track, a stationary housing at the opposite edge of the door and having slots therein, a movable housing within the stationary housing, a spring engaging the movable housing and a roller mounted in the movable housing and having its trunnions slidable in the slots of the stationaryhousing, substantiallyas described.
2. The combination with a car having an opening in the side thereof, of a door, a track above and below the opening, a roller mounted at one edge of the doorand engaging the adjacent track, a stationary housing at the opposite edge of the door, and having slots therein, a U-shaped and movable housing within the stationary housing, a bow-spring fixed to the U-shaped housing and engaging the stationary housing and a roller mounted in the U shaped housing and having its trunnions extended and slidable in the slots of the stationary housing, substantially as described.
The combination of a stationary housing having two side portions respectively formed with oppositely-(lisposed slots, a U-shaped housing movable between the side portions of: the stationary housing, a roller journaled in the U-shaped housing and having its trunnions extended to and respectively movable in the slots of the stationary housing, and a spring carried in the stationary housing and connected to the U-shaped housing, substantially as described.
4. The COHlblllttlJlOll, of a stationaryhousing composed of two side portions, one of which is formed with a transverse plate and the other being formed with an opening receiving a portion of the transverse plate, the parts of the side portions outward from the transverse plate being each formed with a slot, a roller located between the slotted portions of the stationary housing and having its trunnions extended to and movable in the slots of the same, and a spring bearing on the transverse plate and connected to press IIO the trunnions of the roller substantially as described.
5. As a new article of manufacture, a housing composed of two side portions, one of Which has a transversely-extending plate and the other having an opening receiving a portion of the transverse plate whereby tWo divisions are made of the space inclosed by the side portions, the side portions of one division being formed with bearings, and a roller 10 mounted in the bearings, substantially as described.
