DOOR-HANGER.
Specication of Letters Patent.
Application filed July 7, 1911. Serial No. 637,381.
To all 'whom-15 may concern:
Be it known that I, ABRAHAM PERLMAN, a citizen of the United States, and resident of the city of New York, in the count-y of New York and State of New York, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification.
This invention relates to door hangers for edgewise movable doors, and is particularly adapted for use in connection with elevator doors, but it is to be understood that the invention can be used for any purposes where* init is found applicable. v
One of the objects of the invention is to provide a hanger of the class referred to having as an element thereof a series of bearing balls and further having means in a manner as hereinafter ,set forth associated with said balls whereby the weight of the door rests upon the aXis of said balls in lieu of the side thereof whereby the opening and closing movements of the door are facili tated.
A further object of the invention is to provide a door hanger of the class referred to with means in a manner as hereinafter set forth whereby friction is reduced to a minimum and the door rendered as near noiseless as possible in its action during the opening and closing movements thereof.
Further objects of the invention are to provide a door hanger which is comparatively simple in its construction and arrange* ment, strong, durable, eiiicient in its use, reducing friction to a minimum, comparatively noiseless, readily set up and comparatively inexpensive to manufacture.
With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specically described and illust-rated in the accompanying drawings wherein is shown an embodiment of the invention but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views: Figure 1 is a front elevation broken away showing the adaptation of a door hanger in accordance with this invention in connection with the wall of an elevator shaft. Fig. 2 is a cross sectional view thereof. Fig. 3 is an elevation of a modified form of hanger, and, Fig. 4 is a cross sectional view of Fig. 3.
Referring to the drawing by reference characters, that portion of the shaft of an elevator located directly above the door opening is indicated by the reference character 5 and is shown by way of example, as a rectangular plate broken away at one end. Secured to the outer face of the plate 5 near its top and intermediate its ends is a longitudinally-eXtending relatively narrow spacing bar 6. The bar 6 is secured to the plate 5 by means of screws 7 A stationary bar 8 is fiXedly secured in place against the bar 6 through the medium of said screws 7 The bar 8 is of greater width and thickness than the bar 6 and depends below the latter as clearly shown in Fig. 2. Depending from the bar 6 at each end thereof is a stop 9, the function of which will be presentlyreferred to.
Arranged against the outer face of the plate 5 at the bottom thereof is a spacing bar 1() which opposite the bar 6 and abutting against said bar 10 is a combined track and guide which consists of an inner plate 11,`
an intermediate plate 12 and an outer plate 13. The bar 10, and plates 11, 12 and 13 extend longitudinally with respect to the plate 5 and are of the samevlength as said plate 5 and are fiXedly secured in position to the plate 5 by screws 14. The track comprises the plates 11 and 13 which have rounded top edges forming the bearing or tread portion, a groove 14a being formed between the plates 11 and 13 by reason of said plates extending above the upper edge of the plate 12.
Mounted in the guide groove 14a is a longitudinally-extending shiftable flat bar 16 formed with a series of spaced openings in each of which is loosely arranged a ball 17 which travels upon the combined track and guide. For maintaining the balls 17 in the openings of the bar 16, the latter is provided with laterally-extending cages 18 which project from each face thereof and surround the balls 17 as clearly indicated in Fig. 2. The balls 17 are positioned centrally of the bar 16 and disposed throughout the length thereof. The bar 16 is of less length than the length of the combined track and guide. Mounted upon the balls 17 and overlapping the upper portion of the bar 16 is a longi- Patented Feb. 6, 1912.A
tudinally-movablecarrier formed of an inner plate 19, an intermediate plate 20, and an outer plate 21. The plates 19 and 21 are ofv greater width than the plate 20, the latter being flush at its top with the tops of the plates 19 and 21, and by the foregoing arrangement of plates, a groove 22 is provided into which extends the bar 16. Supported by and depending from the carrier are hanger arms 23 which extend below the combined track and guide and have the top 24 of the door (not shown) attached thereto. The arms 23 'are mounted upon laterally projecting lugs 25 which are attached to the carrier. The carrier is arranged in proximity to the bar 8 and interposed between the carrier and said bar 8 are rollers 26 traveling upon the top of the carrier and against the lower edge of the bar 8. The shafts 27 of the rollers are connected together by longitudinally-extending arms 28, one arranged inwardly with respect to the bar 8 and the other outwardly with respect to said bar 8. The arms 28 are of such a width as to overlap the bar 8 and carrier. The outer arm 28 is connected to the bar 16 by a coupling piece 29 which is attached as at 30 to said arm 28 and as at 31 to the bar 16. By such an arrangement the members 28 and rollers 26 move in unison with the bar 16, the movement of the bar 16 in one direction being arrested by one ofthe stops 9 when one of the rollers 26 engages said stop while the movement of the bar 16 in the opposite direction is arrested by the other roller 26 engaging the other stop 9. When the carrier is shifted the arms 28 and bar 16 travel in the same direction but the movement of lsaid arms 28 and bar 16 is half the speed of the carrier. The rollers 26 prevent upward movement of the carrier and owing to the fact that the arms 28'are coupled with the bar 16 upward movement of the latter is also arrested. The bar 16 not only acts'as a support for the balls 17, but also Aprovides means for cleaning the dirt and dust that accumulates in the guide groove 14a therefrom.
` Although in Fig. 1, all of the ballsV 17 are illustrated as being inclosed by the laterally-extending cages, yet it is obvious that the cages need only be employed for those balls that are moved clear of theY edgesof the carrier as the rounded ends of the plates 19 and 21 and 11 and 13 will maintain the other balls 17 in position.
The construction shown in Fig. 1 can be employed for moving two doors in the sameV direction, 'the other door being hung from the bar 16. As the bar 16 travels half the speed of the carrier, it is obvious that by the time that door which is hung from the carrier is moved to open or closed position, the door hung from the bar 16 will also be shifted to the desired position'. Itis thought Vbar 32 as to depend below the same.
unnecessary to illustrate the hanging of the second door from the bar 16.
In the modification as shown in Figs. 3 and 4, the reference character 32 denotes a channel bar which is secured to the elevator shaft in proximity to and above the door opening and which has ixedly secured to the forward face thereof the spacing plate 33 of the same length as the channel bar 32 and which is so disposed with respect to the The top edge of the plate 33 is spaced from the top of the bar 32. Secured against the plate 33 is a flat bar 34 ofthe same width as the width of the bar 32 and which in connection with said bar provides a guide groove 35. The top of the bar 34 and the upper corner of the bar 32 is rounded as at 36 to provide a track for the balls 37 which are mounted in a -longitudinally-extending rectangular shiftable bar 38 which corresponds to the bar 16 shown in Figs. 1 and 2. Laterally-extending cages 39 are provided for the balls 37 in the bar 38. The bar 38 has its lower portion extending into the guide groove 35 and said bar 38 is of less length than the bar 32. That portion of the plate 33' which depends from the bar 32 is indicated by the reference character 40 and it constitutes a track for a purpose to be presently referred to.
Mounted upon the balls 37 and straddling .the upper portion of the bar 38 is a carrier formed of an outer plate 41, an intermediate plate 42 and an inner plate 43. The intermediate plate 42 is of less width than the plates 41 and '43 but is flush at its top with the tops of the said plates 41 and 43 and these latter in connection with the plate 42 provide a guide groove 44 for the upper portion of the bar 38. The plates 41, 43 constitute a track and have their lower edges rounded to provide a tread portion on which the balls 37 travel. The plates 41, 42 and 43 in this construction constitute the carrier, and are connected together and reinforced by an angle iron 46 which is mounted upon the top of said plates and extends against the rear face of the plate 43 as well as depending below the plate 43 to provide what maybe termed a stop arm 47 whichr extends in the path of stops 48 that project from the wall of the elevator shaft 'for limiting the movement of the carrier in either direction.
Fixed to and depending from the carrier are hanger arms 49 each having its lower end formed with an inwardly-extending flange 50 carrying a coupling means 51 for connecting the upper portion 52 of the door to its respective hanger arm. Each of the hanger arms 49 is provided with an inwardly-extending boltl 53 arranged below the plate 33 vand which is provided with a roller 54 adapted to travel against the portion 40 of the. plate 33 thereby preventing vertical movement of the carrier. The rollers 54 are retained upon the bolts 53 by the pins 55 which extend through the inner end of the bolts 53.
In the construction shown in Figs. 3 and 4, the bar 38 when shifted has half the speed of the carrier so that if desired, a door can be hung from the bar 38, that is to say, when it is desired to shift a pair of doors traveling in the same direction. In both constructions, the weight is directly upon the axes of the balls in lieu of the sides and which reduces friction to a minimum thereby facilitating the opening and closing movements of the door.
What I claim is:
l. In a door hanger, a supporting member, a carrier suspended therefrom and shiftable longitudinally of the supporting element, saidcarrier comprising side plates and an intermediate spacing plate all connected t-ogether, the spacing plate being of less width than the side plates to form a guide groove between the latter, a shiftable bar having its upper portion received in said groove, balls mounted in said bar between the upper and lower edges of the bar and projecting on opposite sides of the bar, a. track on which said balls travel, said track having a guide groove for the lower portion of said bar, and hanger arms suspended from said carrier.
