CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 512,004, dated January 2, 1894:.

Application filed January 18, 1893- Serial No. 458,807- (No model.)

To all whom it may concern:

Be it known that I, FERDINAND E. CANDA, of the city, county, and State of New York, have invented a new and Improved Car-Door, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved car door, more especially deslgned for refrigerator cars, and arranged to effectually render the car air-tight at the door opening, or to permit a free ventilation Whenever desired.

The invention consists of certain parts and details, and combinations of the same. as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawlngs, forming a part of this specification, 1n whlch similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional plan view of the improvement as applied. Fig. 2 is an enlarged sectlonal plan view of the improvement show- 1n g the door seated in the car door opening. Fig. 3 is a like view of the same showing the door unseated and to one side of the car door opening, the latter being closed by a ventilating screen door. Fig. at is a sectional plan View of the housing for the toggle lever. Fig. 5 is a side elevation of the same. Fig. 6 is an enlarged side elevation of the improvement with parts broken out. Fig. 7 is a side elevatlon of part of the inner door. Fig.8 is a sectional side elevation of the fastening device for the inner door. Fig. 9 is a transverse section of the same. Fig. 10 is an enlarged transverse section of the improvement. Fig. 11 is a face View of a modified form of the actuatingdevice for the outer door. Fig. 12 1s an enlarged sectional plan view of the same on the lines 12-12 of Fig. 11; and Fig. 13 is a sectional plan view of a modified form of the improvement.

Doors for refrigerator cars as at present constrncted, are usually attached to the car body with hinges and are usually made to swing outward, and from experience it has been found almost impossible to keep them in ad- 3' ustment owing to their excessive weight, and also from any undue strains in the body of the car, they sag, thereby failing to properly seal the opening or accomplish the uses for which they are designed. It therefore follows that the temperature adjoining such doors cannot be uniformly maintained with the balance of the interior of the car, however perfect the insulation may otherwise be. The result is that frequent, large and serious loss follows, particularly to fresh meats or other perishable articles, which may occupy a space in the center of the car and adjoining the doors.

The object of the invention presently to be described in detail, is to overcome these serious objections and to furnish a door which is absolutely air-tight, adjustable to any ordinary irregularity, and not affected by any sagging of the car body,and which also enables me to construct a wider car and thus secure the benefits of the additional space adjoining the ice bunkers.

The car body A is formed in each of its sides B, with an opening 0 about twice the size of the car door proper, and having at its sides door posts 0' which act as jambs connected with each other at the top by a suitable transom O as plainly indicatedin Fig. 6.

To the post 0 and transom O is secured an inner frame D consisting of posts, D', D and D transom D, and sill or threshold D for the door proper. See Figs. 1 and 10. In this inner frame D between posts D and D is formed the door opening D, while the remaining part D of the frame, extending between the posts D and D is sealed up and insulated similarly to the balance of the body of the car, as will be readily understood by reference to Fig. 3. This sealed up part D forms a recess or pocket in one side of the opening 0 to receive the car door E and its frame F as hereinafter more fully described.

A door E is adapted to be seated on suitable seats D? formed on the inner frame D around the opening D, and this door is supported on the rear face of a frame F, mounted to slidelongitudinallyin the openingOformed in the respective side B of the car body A. The door E is mounted to slide transversely on its frame F, so as to be moved from the rear face of the frame F onto the seat D at the time the said frame F is in front of the door opening D hen the door E is on the back of the frame F, it extends into the opening in the side B and can be moved with the frame F from in front of the door opening D into one side of the openingC directly opposite the scaled up portion D of the inner frame D. The outer face of the frame F is fiush with the outer face of the side B of the car body A, so that no projection whatever is on the side of the car body when the door is open or closed.

In order to connect the door E with the frame F and at the same time provide means for sliding the door transversely from or toward the frame, to or from the door opening D, I provide sets of toggle levers G and G connecting the door with, the frame and arranged to fold in suitable housings G secured in the said door and frame, as will be readily understood by reference to Figs. 3, 4- and 5. The toggle levers of each set are arranged one above the other, and the pivots of the toggle lovers are pivotally connected by links H and H respectively, with opposite ends of an arm H secured on a vertically disposed shaft I, journaled in suitable bearings I secured to the front face of the door E.

On the shaft I, near its middle, is secured a handle arm I ,-for conveniently turning the said shaft to open and close the toggle levers G and G to move the door E transversely to and from the door opening D as above mentioned. The arm I is formed near its outer end with an aperture 1, for engagement with either of the staples I and 1 secured to the door E at opposite sides of the shaft I. When the arm I is engaged with either staple I or 1 a padlock or other locking device may be attached'to the projecting end of the respective staple to lock the arm I in place. When the arm I is thus locked in place 011 either staple I or 1 the door E is held in a locked posit-ion either on the frame F or on the seat D of the door frame D. See Figs. 2 and 3.

As illustrated in Figs. 11 and 12, the pivots of the toggle levers G and G, are pivotally connected with arms H and H respectively, mounted to slide longitudinally in suitable bearingsI-P attached to the front face of the door E. The several arms H are rigidly connected with each other by a vertically-disposed bar H and the several arms H are likewise rigidly connected with each other by abar'H The two bars H and H are pivotally-connected by links .I and J with a lever J at opposite sides of its fulcrum J located on the front face of the door E. As the pivotal connections of the links J and J are on opposite sides of the fulcrum J of the lever. J the bars H and H are caused to move toward each other when the said lever is moved to the right, so that the toggle levers G and G are opened and thereby push the door E transversely away from the frame F and into the seat D on the door frame D at the time the said frame F is in front of the door opening D WVhen the lever J is moved to the left, the bars H and H are caused to move from each other whereby the toggle levers G and G are closed and the door E 1s moved out of its seat D into the opening 0 and onto the back ofthe frame F. The free end of the lever J can be locked in either above mentioned right or left hand posltions by engaging a catch J or J on the door E.

In order to prevent the bars H and H from bending I prefer to connect the same at or near their middle with rods J fitted to slide longitudinally in bearings J secured to the door E and similar in construction to the bearings H previously described.

In order to shift the frame F with the door E longitudinally, Iprovide the said frame at the upper end with guides L fitted to slide on a longitudinally-extending rail L attached to the under side of the transom C Thelower end of the doorE is provided with hangers N carrying the grooved pulleys N, mounted to travel on the longitudinally-extending rail N arranged in the opening 0 and fastened to the sill in the bottom of the openlng 0. It will be seen that by this arrangement, the operator having hold of the frame F can readily shift the latter longitudinally so as to move the door E in front of the door opening D for closing the latter by moving the arm I or lever J 2 to the right, as above described, or the said frame can be shifted into one s1de of the opening 0, in front of the sealed part D -of the frame D when access to the car 1s desired through the opening D. In order to relieve the toggle levers of the weight of the door E, I prefer to mount the latter on transversely-extending guideways L and N formed transversely on the guides L and N respectively, the said guideways being engaged by suitable castings E and E respectively, secured on the top and bottom edges of the door E, as plainly shown 1n Figs. 2 and 10.

In order to close the door opening'D at the inside I provide an auxiliary door K (see Figs. 7 and 10) having at its upper end hangers K mounted to slide on a rail K secured to the inner face of the transom D not in use the door K is moved away from the opening D and moved opposite the scaled up part D of the door frames.

The auxiliary door K is adapted to be, moved firmly onto the inner faces of the posts D and D the sill D and the transom D by special mechanisms 0 illustrated in detail in When Figs. 8 and 9, and attached to the door near the corners thereof, as indicated in dotted lines in Fig. 7. Each mechanism 0 1s provided with a recessed plate 0 secured toand arranged flush with the outer face of the auxiliary door K and on it is pivoted the arm 0 adapted to be either folded onto the recess of the plate 0 or swung outward to engage with its aperture an eccentric pin or stud O mounted to turn in a bearing 0 secured to the inner side of the respective post D or D Each of the eccentric pins is formed with a handle 0 to turn the respective stud so as to cause the latter to exert an outward pull on the pivoted arm 0 whereby the auxiliary door 1s moved in the same direction until firmly seated on the inner faces of the posts D, D the sill D and transom D It will be seen that the auxiliary door is thus seated and locked in place by the several mechan- 1sms O each of which is operated from the outside of the car at the time the door E is moved to one side away from the opening D.

In order to properly ventilate the car when the doors E and K are not in use and moved to one side of the door opening D ,I provide an outer ventilating door Q carrying on its upper end hangers Q fitted to slide on a longitudinally-extending guide rail Q secured to'the respective car side as plainly shown in Figs. 6 and 10. On the lower end of the door Q are secured downwardly and inwardlyextending lugs or arms Q abutting against the inside of a rail Q secured to the side of the car near its lower end.

The door Q is formed with a screen section Q and a solid or sealed up section Q the entire door being of size to cover the entire opening 0 as illustrated in Figs. 1 and 3. In this case the screen section is in front of the door opening D and the sealed up section Q is in front of the frame F and the door E thus forming a shield for the same. The screen section Q permits air to pass to the interior of the car to ventilate the same.

As illustrated in Fig. 13, hinged doors P may be employed on the frame D, the said hinged doors, when swung outward, folding into two pockets in the side parts of the opening 0 in front of the sealed portions D of the frame D-as plainly shown in the said figure, so that the hinged doors do not present any projection whatever on the side of the car;

It is understood that any well-known system of insulation and framing for the car door, 850., applicable to the construction above described, may be used, and the joints of the car door with the car body can be packed with rubber hose or any of the well-known methods for such packing to render the door completely air-tight.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A car, provided with an opening in its side, a separate door frame secured within the said opening, the said frame having an opening adapted to receive the door, and a sealed part located laterally on the said opening and forming a recess or pocket in the side of the car for the reception of the door when the same is removed from the said opening of the frame, substantially as shown and'described.
