DOOR HANGER Filed April 10 1931 Patented Mar. k14, 1933 UNITED stares PATN'r .FRANK E. HOWARD, OF HARTFORD, GONNECTICUTASSIGNOR TO J' AMES L. `VHO'VV-.LIB/Il) 8a COMPANY, OF HARTFORD, CONNECTICUIA CORPORATION OF CONNECTICUT Doon HANGER Application filed April 10,

, rIhis invention relates, generally, to sliding doors and has particular reference to hangers therefor. As an instance of ause to which the structure of the present invention may be applied, reference may be had to the hanging of doors of subway. cars and the like.

rIhe aim of the invention is to provide an improved hanger having various features of novelty and advantage and which is particularly characterized by its strength and durability, by its simplicity, by its effectiveness in operation, and by the ease and facility with which the parts may be made, assembled and dis-assembled. v

.`More particularly, my invention comprises a Vcarriage supported by a pair vof sheaves adapted to ride upon a track, anda plate to which the door is connected and from which itis suspended, the parts being so related that the plate may havefa limited swinging movement inthe plane of the door. -The plate is so supported by and associated :with the carriage as to properly distribute the weight of the door on theV sheaves. The pivot pin to which the plate is connected is supportedv in a novel and advantageous man# ner so as to permit of ready assembly' and to prevent excessive wear or derangement-of the parts. I

Other objects will be in part lobvious and in part pointed out more in detail.

The invention accordingly consists in the features of construction, combination of elements'and arrangement of parts which will be exemplified in the construction hereinafter set forth and the Yscope of the application of which will be indicated in the appended claims.

In the accompanying drawing, wherein I have shown, for illustrative purposes, one embodiment which the present invention may take: y Figure 1` is a front view of my improved door hanger, a portion of the track, and a portion of the door;

Fig. 2 isal longitudinal horizontal section taken substantially on line 2-2 of Fig. land looking in the direction ofthe arrows;

Fig. 3 is an end view of what is shown in Fig. 1; and

193.1. serial No. 529,027.

4'Fig-4c is a perspective view of the carriage.- `Referring to the drawing in. detail, Adenotes `a track of any suitable sort on which the sheaves of the hanger are adapted to roll,

and B is a door suspended by means of the hanger. Y

My lmproved hangerr includes a carriage C which preferably comprises an integral member formed by casting or drop forging operations. ff The carriage C comprises an elongated link having, at its central portion, arearwardly projecting boss or hub 10, the opening 11 of which extends entirely through the carriage.. The link has a central portion 12, from the opposite ends of which extend earsy 13 preferably of lesser thickness .than the central portion. These ears have vopenings lil'adapted lto receive'thepins 15 -on which the sheaves are supported. The for-` ward face o'f the central portion has aj recess lwhich is adapted to accommodate the ear 17 of the attaching plate D. i

Each of thesheaves is supported in a man-` ner similar to that disclosed in my Patent No. 1,571,334 issued February 2nd,'1926 and entitled Door hanger. In accordance with that disclosure, each of the pins 15 has an integral flange. 20, a stud 21 projecting forwardly from the flange, and a rearwardly extending body portion having threads 22. The

stud 21 is adapted to engage in the openingv 14, the pin being preferably made of a metal sufficiently soft thatthe outer end of the stud may be riveted or headed,- as illustrated. The flanges 20 engage against the inner facesof the respective ears 13 of the carriage.

Threaded onto the pins 15 are bushings 23 having integral flanges 24 at their rearends. Surrounding the bushings, and interposed between the flanges 2O and 24, are sheaves or rollers 25, and between these: sheaves and the cylindrical portions of'the bushings are anti-friction members or balls26, two rows of such'balls being shown'in'each instance.

`The rows of balls may be separated by aweb 27 on the sheave.

"The attaching plate D may be of any suitableconstruction, it here havinga body pore tion 30 and thepear 17 offset rearwardly from the ,body portion. The numeral 31 designates strengthening ribs. Obviously, the attaching plate may be flat, and it may be secured to the door in any suitable manner, as by means of screws 32. v

For the purpose of pivotally connecting the attaching plate to the carriage, fa pin 35 is provided, this pin also preferably being made of a metal which is suflicientlyv soft to permit heading of its outer end. This pin has an integral flange 36, a stud 37 extending forwardly from the flange, and a rearwardly extending body portion threaded as at 38. The flange 36 is seated in a rabbet 39 at the vforward end of the opening 11,'and the forward face of the flange is engaged bythe rear face of the ear 17 of the attaching plate.

Thestud37 extends through an opening in the ear and its outer end is headed or riveted as illustrated. The stud is swelledl in the opening so as to prevent rotation between the pin 35 and the attaching plate. Thenumeral 40 designates a hardened bushing threaded on the pinV 35 and engaging in the boss 10 of the carriage. This bushing has, at its rear end, an integral flange 41 over`` lying and adapted to engage the rear end of the boss 10. The bushing 40 is adapted to rotate or turn in the boss 10 so as to permit of swinging movement of the door relative to the carriage. The rear end of the bushing 40, as shown in Fig. 2, may have recesses 42 with which a Spanner or other tool is adapted to cooperate when it is desired to turn the bushing relative to the pin 35. The bushing may be locked in any position of adjustment on the pin 35, as by means of staking, as indicated at 43. The bushings 23 may also be provided with recesses corresponding to the recesses 42. y

It will readily be seen from the foregoing description, taken in connection with the accompanying drawing, that theV parts may be readily assembled and dis-assembled. The sheave units may be connected to the carriage j as described in my saidPatent No. 1,571,334.

The pin 35 may be first connected to the plate D by riveting the stud 37 in place. Then the hanger plate is brought to position where the threaded portionv of the pin 35 projects through the hub 10. The bushing'l() is then threaded onto the pin 35. The bushing 40, the pin 35 and the plate D constitute an assembled unit which is adapted to turn relative to the carriage, bearing surfaces being provided between the bushing and the wall of thev opening 11. The pin is held against axial movement due to the engagement ofthe flange 36 and the vflange 41 on the opposite ends of the hub 10. 7

Tt will further be observed that theboss 10 projects rearwardly from the link portion of the carriage and is located between the sheaves, .and also the ear of the Vattaching plate is substantially in the plane of the link portion of the carriage, this arrangement permitting of a compact structure and one wherein the strains and stresses are distributed to the best advantage.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted-asillustrative and not in a limiting sense.

Itis also to be understood that the language used inthe following claims is intended to cover all of the generic and specific features of the invention herein described and all ystatements of' the scope of the invention which, as apmatter of language, might be said to fall therebetween.

I claim as my invention:
