DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 643,654, dated February 20, 1900.

Application filed April 19, 1899- 1'0 all whom, it may concern:

Be it known that I, GRAHAM P. JONES, a citizen of the United States, residing at Chi cage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sliding-Door Hangers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to sliding-door hangers, and especially to that class of hangers adapted for association with doors which are raised and lowered to and from their sliding or operative position by means of suitable mechanism provided for that purpose. Heretofore in this class of sliding doors great difficulty has been experienced in preventingthe hangers from becoming displaced or raised off of the rail.

One of the objects of my present invention is to provide certain improvements in hangers adapted for this class of doors whereby the hanger cannot be raised off or displaced from the rail with which it is associated. Also in applying the old form of hanger it was necessary for the operator in assembling the parts to carefully measure and adjust the same with reference to the distance between the top of the door and the top of the rail in order that the required amount of play or movement should be provided. It was necessary to employ a strip equal in width to this dis tance from the top of the door to the top of the rail and by it adjust the hangers on the door so that the eyes or bolt-holes in the upper ends of the hangers, to which the lifting and lowering levers are fastened, should come in proper relation to the rail.

Another object of my invention is to pro vide certain improvements in hangers whereby the proper assemblage of parts is assured without any measurement or calculation and without the employment of any additional means. Also in doors havingalateral movement in order to clear a closing strip or cleat when slid back and forth the wedge or incline which is employed in certain forms of this class of doors to move the door laterally opedge to coact with the wedge.

Serial No. 713,676. (No model.)

crates directly upon the inner face of the door itself, which is usually beveled at its upper In this type the door rapidly became worn at its point of contact with the wedge, in some cases to such a degree that the required amount of lateral movement was not obtained.

A further object of my invention is to provide certain improvements in hangers adapted for doors of this class whereby the hanger is provided with a. wiper or rubbing-face which coacts with the Wedge or incline.

Other and further objects of my invention will appear from the specification.

To obtain these various objects and results, my invention consists in the construction and arrangement of the hangers, as hereinafter shown and described, and specifically pointed out in the claims.

The invention may be applied to any form of sliding door which is arranged to travel upon a track, but is more particularlyapplicable to the doors of freight-cars, and for the purpose of illustration I have shown it in the drawings applied to a door of this type.

In the drawings accompanying this specification and forming a part thereof, Figure 1 is a side elevation of a car-door embodying my improvements. Fig. 2 is a cross-section of the doorway, on an enlarged scale, the door and its hangers being in position in which they are shown in Fig. 1. Fig. 3 is a detail sectional View showing the position of the parts when the door is raised to its operative or sliding position; and Figs. 4 and 5 are detail views of the side and rear face, respectively, of the hanger.

In the drawings the reference-letter A indicates the side of a car, A the car-door, and A the top rail, adapted to receive the sheaves a, which support the door when it is raised to its operative position and upon which it slides back and forth to cover and uncover the door-opening.

The reference-letter a represents a cambracket secured to the side of the car on the run side of the door-opening near its lower right-hand corner and having an inclined inner face by which the door is forced laterally against the side of the car when the door is at rest. A supporting-bracket a is arranged on the opposite side of the door-opening and may or may not be similar to the cam-bracket a These brackets in part sustain the weight of the door when the latter is lowered into its closed or inoperative position.

The sheaves or wheels a are journaled in raising and lowering levers a a the outer ends of which are pivoted to the hangers B and B, respectively, which in turn are secured to the upper corners of the door, as shown in Fig. 1, and extend over the rail, as shown in Figs. 2 and 3. The inner ends of the levers are slotted and are connected by a bolt, which passes through these slots, to an operating-rod B as shown in Fig. 1, which extends downwardly through suitable guides and terminates in any convenient form of handle. Any suitable stop may be provided to prevent excessive downward movement of the operating-rod to prevent the raising and lowering levers from binding on the top rail.

The hangers, as shown in the detail views in Figs. 4E and 5, consist of metallic straps or castings having suitable holes in their body portions 1) to receive suitable bolts for securing them to the door. The upper portion b of each hanger overhangs or extends inwardly over the top rail and is provided with an incline or cam b which serves to force or carry the door obliquely and snugly against the side of the car or the door-jambs when it is lowered and allow it to move out of contact therewith when it is raised. The overhanging portion forms a seat or rest which bears upon the rail when the door is lowered to sustain the latter in conjunction with the brackets a and (L The upper portion 11 of each hanger is provided with an eye Z) to receive a bolt for attaching its associated raising and lowering lever.

The door normally rests upon the cam-hangers and upon one or both of the brackets, according as itisin position over the door-opening or to one side thereof, the raising and lowering levers a a then being in the position indicated in Fig. 1 and the weight of the door being off the sheaves a a. When it is desired to move the door laterally, the operator pulls down on the handle of the operating-rod and raises the door by means of the raising and lowering levers, the journals of the sheaves serving as fulcrums. In this position the door is raised from its seat in the brackets a a and the overhanging portions of the hangers and rests upon the sheaves a a, by which it may be slid back and forth, as shown in Fig. 3.

The inner face of each of the hangers B B is provided with a stop device 11*, which is preferably in the form of a lateral web or flange and which is preferably cast integral with the same, though it is apparent that it may be separate therefrom and attached in any suitable manner. The web is located at approximately the top of the body portion 1) of the hanger, where the latter begins to curve outwardly to form the overhanging portion b It-is made substantially the width of the top of the door, and its location on the hanger is such that it comes in contact with the under side of the rail before the hanger can be raised far enough to allow the inner end of its overhanging portion to be displaced from its proper position with relation to the rail. The relation of the web and overhanging portion of the hanger is such that the former contacts with the under side of the rail before the latter is raised high enough to pass over the top of the rail. In this manner the hanger cannot be raised off the rail or become displaced.

In the operation of the device the stop mechanism associated with the operating-rod B will normally prevent the door from rising so far that the webs of the hangers will contact with the rail, so that the latter do not under normal conditions in any manner interfere with the movements of the door. It often happens, however, that in closing the door the operator pushes upon one end of it and causes it to tilt upward, in which case the hangers become displaced unless provided with some suitable device, such as the web or stop above described. Vith this construction the accidental displacement of the door is rendered impossible.

In certain types of doors it is desirable to provide a wedge or incline, such as D, at the upper right-hand corner of the door-opening, by which the dooris moved laterally or away from the side of the car as it is raised. This construction isused where a closing strip or cleat d is attached the run side of the dooropening to make a dust-proof closure. This wedge is placed at the upper right-hand corner of the door-opening in the path of the top of the door, so that the latter is forced laterally away from the car sutiiciently to clear the cleat when itis raised. Heretofore in employing this device the door itself came in contact with the wedge and in course of time became worn, so that in some cases it did not receive the amount of lateral movement required to clear the cleat. By providing the hanger with a .web extending across the top of the door to web itself comes in contact with the wedge or incline C, thus forming a wiper or rubbin g-face to coact with the wedge. The face of the web is preferably beveled, as at Z2 to correspond with the incline of the wedge in order to work more smoothly and satisfactorily.

The web or flange of the hanger enables the operator in assembling theparts to fix the distance between the top of the door and the top of the rail, which it is necessary to accurately adjust, without the use of any measurement or calculation or additional means, as before pointed out. The amount of play or movement in doors of this character is so IIO small that this adjustment must be made within a very small fraction of an inch. By providing the hanger with a web which is arranged in such relation to the other parts that the correct adjustment shall be obtained by merely placing the web on the top of the door the hanger is adjusted in proper position to provide the required play and is necessarily placed in the required vertical position and so retained, the assembling of the parts is rendered easier and absolutely accurate, and the entire construction is simplified. and improved.

Having thus described my invention, what I desire to claim and secure by Letters Patent is 1. A hanger for sliding doors comprising a body, an overhanging portion forming a seat and provided with an eye for attachment of its operating-lever and with an incline upon its inner end, and a lateral web of substantially the width of the door provided on its inner end with an incline, the distance between the web and the base of the incline of the overhanging portion being less than the width of the track to which said hanger is adapted.

2. The combination, with a sliding door, levers provided withsheaves, a track upon which said sheaves run, an operating device for said levers, of hangers in which the levers are pivoted, an incline for forcing said door laterally when raised and a web on one of the hangers coaoting with said incline, substantially as described.

3. The combination, with a sliding door, a track from which said door is suspended when operated, sheaves running 011 the track, levers in which the sheaves are journaled and by which the door is raised and lowered, of hangers in which the levers are pivoted, inclines for carrying said door inwardly when lowered and outwardly when raised, and a web on one of the hangers providing a wiper for said latter incline, substantially as described.

4. The combination, with a sliding door, a track from which said door is suspended when operated, raising and lowering levers carrying sheaves on which the door is slid, of camhangers in which the levers are pivoted, one of said hangers having a lateral web, and an incline or wedge in the path of the web, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GRAHAM P. JONES.
