CAR-DOOR.
Specification of Letters Patent.
Patented Dec. 3, 1907.'
Application filed Decembei 19, 1906- Serial'No. 348.546.
To all whom it'may concern:
Be it known that 1, JOHN N. MARQUETTE, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful 1m rovements in Car-Doors, of which the fol owing is a specification.
, This invention relates to improvements 7 in car -doors and is particularly an improvelaterally-moved position as it would appear ment on that class of doors which are hung so as to be moved in and out of the frame or opening and to also be moved laterally with res met to said opening.
he object of the invention is to provide an improved construction of mechanism of this class.
The improvements are illustrated in the drawing herewith, in which 4 Figure 1, represents a side elevation of the car body and my im roved door and operating mechanism attached thereto. Fig. 2 is a vertical section through the sa1ne,the section being taken on the line 22- of Fig. 1. Fig. 3 is a horizontal sectional view through the body, door and operating mechanism as the same would appear on the line 33 of Fig. 1.- Fig. 4 is a similar view with the exception that the door is shown in the on the line 4-4 of Fig. 1, and Fig. 5 1 lustrates an enlarged sectional detail of the operating arm and coacting devices.
Referring to the drawings by numerals, 1, designates thesside of the car body or the receptacle; 2, the opening therein and, 3, the frame around said opening. In the resent instance the opening in the frame is eveled.
Above the o ening the body is provided with an upper orizontally-extending rail, '4,
s and below said opening said body is provided with a lower horizontal rail, 5. These rails may be attached to the body in any suitable 1nanner but in the present instance a plurality of blocks, 6, are interposed between the rails and body whereby to sustain said raigls in an off-set or spaced position from the b0 A metallic strip, 7, is secured close against the side of the car bod aboutmidway between the two rails an this strip serves to keep the door from frictional contact with the body during its lateral travel as will presentl appear. An angle plate, 8, is also attache to the body and serves as a stop.
against which the door contacts to limit its 'lateral travel.
The door, 9, may be of any suitable con-- struction but in the present instance it is provided wlth beveled horizontal and verti- 'cal edges, 10, to conform to the shape of the opening, 2 in the body so as to make a tight joint or closure when forced into the opening. By the door being forced tightly into the door-o ening, and the outer surface of the door ush with the outer side of the car there will result a complete exclusion while the car is in motion, of sparks, and hot particles of cinders from the locomotive.
Clips, 11, take over or loosely engage the upper rail, 4, and are provided with lateral perforated extensions, 12. These clips may be constructed in any suitable manner so long as they securely engage the upper rail and are slidable thereon. Vertical shafts, 13, and, 13, have their upper ends projecting through the said )crforations in the clips and are rotatably held therein by means of nuts, 14, which engage their upper rojecting end-s. These clips, 11, are esigned merely as traveling guides for the upper end of the door and are not employed to sustain the door as the latter is supported at the bottom on carriages as will presently be described.
Adjacent the bottom of the door and mounted on the lower rail, 5, are a plurality of traveling carriages or supports, 15. These carriages are mounted on grooved rollers, ,16, which travel on the rail, 5, and their fiat upper surfaces, 17, are substantially flush with the lower edge or sill of the opening in the car-body, as clearly seen in Fig. 2. Lateral projections, 18, are provided on the carriages and said projections are perforated so as to receive the lower ends of the two vertical shafts. A bar, 19, extends horizontally between the carriages and connects the latterse-as to keep them properly spaced.
Adjacent their ends the vertical shafts are each provided. with a sleeve, 20, from each of which an arm, 21, projects laterally. These sleeves and arms are ri id with the shafts and are rocked in a horizontal plane with the latter as will presently-be described. The ends, 22, of these arms are bifurcated and are pivotally connected to brackets, 23, which latter are rigidly secured'to the door An operating bar, 24, is rigidly carried on the shaft, 13, and said bar carries a pivoted arm, 25, at its end. This pivoted arm is provided with a perforation through which a rigid stud, 26, on the door projects when the pivoted arm, 25, is swung against the side of the door, as in Figs. 1 and 5. A pin, 27, carried on a chain, 28, is passed through a hole in. the rigid stud and serves to hold the arm, 25, against the door only when the latter is closed.
A locking lever, 29, is pivotally mounted on one of thedower arms, 21, adjacent the shaft, 13 (see Figs. 1, 3 and 4) and this lever extends inwardly and is provided with a perforation in its end which takes over a horizontal stud, 30, also on the door and preferably adjacent the bottom thereof, A pin or seal, 31, may be attached to the stud, 30, to prevent the unauthorized opening of the door without detection.
In the operation of opening the door the seal or pins, 27, and, 31, are first removed and the locking bar, 29, is drawn outwardly from engagement with the stud, 80. The operator will then grasp the knob on the pivoted. arm, and draw said arm away from the door as indicated in broken lines in Fig. 5, and the preliminary outward movement of the arm will first release the latter from the stud, 26, on the door while the further outward movement of said arm will rotate the shaft, 13. The rotation of this shaft will cause the arms, 21, at the upper and lower ends of the shaft to swing outwardly. The outward swinging of the arms, 21., of shaft, 13, will cause the rotation of the other shaft, 13 the same as though the two shafts were directly connected. In swinging outwardly the door is deposited onto the flat top surfaces of the traveling carriages, 15, and the weight of the door is sustained by said carriages while the clips,
, 1 1, at the top of the door merely serve to maintain the door in a vertical position and also act as bearings for the upper ends of the shafts, l3, and, 13 After the operating arm, 25, has been drawn outward sufficiently to deposit the door on the carriages, 15, fur
operation of the arm, 25.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is,
1. The combination with the car-body having a door-o ening, of a rail on the carbody below sai opening; carriers traveling on said rail andhaving a flat top surface substantially flush with the bottom of the said door-o )ening; a door; brackets on the door; vertiea shafts having their lower ends rotatably mounted on the said carriers, and arms attached to the vertical shafts and pivotally connected with the said door-brackets.
2. The combination with the car-body having a door-opening, of the traveling 'car riers at the side of the body; shafts having their lower ends engaged with said carriers; bearings at the upper ends of the shafts for maintaining them in a vertical position; a door; arms rigid with and carried by the said shafts and pivotally connected with the door, and a bar, 24, also rigid on one shaft for rotating the shaft to cause the door to move from the door-opening onto the carriers, and said bar having a jointed arm to be fastoned to the door.
In testimony whereof I aflix my signature in presence of twowitnesses.
