HANGER FOR SLIDING DOORS Filed Sept. 29, 1941 z 1:- I m Patented June 22, 1943 UNITED STATES PATENT OFFICE HANGER, FOR SLIDING DOORS Ralph L. Long, San Diego, Calif.
Application September 29, 1941, Serial No. 412,895
The main object of the present invention resides in the improved type of bearing by which the roller members are rotatably connected to the door supporting bracket.
Another object of the invention is the provision of a longitudinally extending elongation on the supporting bracket or shank which assures the proper alignment of the rollers within the supporting trackway.
A further object of the present invention resides in the connection between the lower end of the supporting shank and the upper surface of the door.
While in the attached drawing, I have shown my invention in its preferred form it will be obvious to those skilled in this art, that it is not to be considered in such a limited manner, but is susceptible of various other changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art, or as are specifically set forth in the appended claim.
Referring more in detail to the attached drawing, wherein similar letters of reference refer to like parts throughout the several views:
Figure 1 is a transverse sectional view taken through a section of a Wall and showing the hanger in its supported position within a channeled header and with a door indicated in section suspended from the lower end of the shank of the hanger;
Figure 2 is a side elevation of the hanger with one of the roller elements omitted to better illustrate the bearing assembly and with a door in fragmentary section and its connection with the lower end of the shank;
Figure 3 is a transverse view partly in section on line 3-3 Figure 2 looking in the direction as indicated by the arrow;
Figure 4 isa top plan view of the door plate with the bracket shank in section;
Figure 5 is a View of the inner face of one of the roller elements;
Figure 6 is a longitudinal view of the bearing pin on which the rollers are rotatably mounted and showing one end of the roller pintle in section;
Figure '7 is a side elevation of a modified type of hanger connection to a door and Figure 8 is an end elevation with the lower end of the supporting shank in section to better illustrate the socket for the reception of the enlarged end of a screw or similar headed member.
In the drawing I have used my composite type of header which forms the subject matter of my oopending application Serial No. 412,894, filed Sept. 29, 1941, but it is to be understood that any type of double faced trackway may be employed. The header as shown is constructed ofwood, the upper sections I0, I I, and I2 being of a relatively light and cheaper grade of stock while the track portion I 3 is of a harder grain or structure. This header is provided with an internal trough or passageway I4 and with a longitudinal slot I 5 heading from the lower face of the header to the passageway I4.
The door hanger which is the essence of the present application has a shank I6, the medial portion of which is longitudinally extended to provide an elongation I'I. This elongated area or surface performs a rather useful purpose in the proper assembly of the door hanger into its desired position in the trackway of the header. The cross area of the slot I5 will permit the reception of the shank only when the area I! is longitudinally disposed therein, thereby assuring that the roller elements will be correctly positioned on the internal trackway.
The upper end of the shank I6 is provided with a cylindrical head I8 which is longitudinally bored as at I9 for the reception of the roller supporting shaft. This shaft has an enlarged cylindrical portion 20 which snugly fits within the bore I9 and extending at either side thereof is a roller supporting pintle 2I-2I. It should be noted here that the ends of the enlarged portion 20 extend slightly beyond the outer faces of the cylindrical head I 8-as indicated at 2222, all for a purpose as will hereafter appear.
The roller members 23-23 are of semi-spherical formation as shown and have internal ribs 24 for the purpose of rigidity. The central portion of each roller has a bored hub 25 which is adapted to fit over one of the roller supporting pintles 2|. The ends of the pintles 2| are bored as at 26 so that the pintle ends can be readily spun or pierced to rigidly fasten the rollers to the pintles and thereby lock both rollers for uniform rotation. In so fastening the rollers to the pintles it will be appreciated that the inner face of the rollers will be forced into engagement with the extended portions of the cylindrical enlargement 20, which will effectively space the roller from direct contact with the cylindrical head l8.
The lower end of the shank as shown in Figures 1, 2, 3, and 4 has an enlarged head 21 which fits into a slotted door plate 28, being retained therein when seated within the recessed portion 29 which snugly receives the head 21.
In the modified form of door connection as shown in Figures 7 and 8 the lower end of the shank is provided with a socket or recess 29' and is slotted as at 30 to receive the headed portion of a screw 31 or similar headed member. As shown the screw 3| is attached to the top surface of the door and is driven therein, leaving just the amount of clearance to snugly engage in the socket 30.
The door in this case is inserted into proper position to engage with the lower end of the depending shanks by a transverse movement within the door opening as fully set forth in my copending application and further as disclosed in my prior Patent 2,207,322, July 9, 1940.
What I desire to secure by Letters Patent is:
A door hanger of the class described compris ing in combination a vertically extending shank having a roller supporting structure associated with the upper end thereof, the lower end of the shank having an inwardly extending recess formed in the body portion thereof, and a screw secured to the top edge of a door with the head of the screw spaced upwardly therefrom, said screw head adapted to be received within the recess in the shank to hold the door in suspended position from the lower end of the shank RALPH L.
