Improvements in Hangers for Sliding Doors or Windows.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
The object of the invention is to design a hanger for a sliding door or window
which will support the door or window so that it may be moved freely without
binding or moving from its proper track; and it consists essentially of a hanger
composed of a pair of bars jointed together and connected to the door and its frame,
substantially in the manner hereinafter more particularly explained.
Figure 1 is a side view partially in section of a narrow door provided with this
improved hanger.
Fig. 2 is a similar view of a wide door provided with this improved hanger.
Fig. 3 is a detail of a hanger when made for a wide door.
Fig. 4 is a detail of bracket.
In the drawing like letters of reference indicate corresponding parts in each
figure but for convenience in describing this invention I shall first refer to the
construction shown in Figure 1.
The bars A and B are joined together by a pivot pin a. The upper end of the
bar A is pivotted at 6 to the bracket which is adjustably connected to the door D
as shown. The lower end of the bar A is provided with a pin d which fits into a
slot made in the bracket E. The upper end of the bar B is pivotted at e to a bracket F
fixed to the door frame G and the lower end of the bar B is provided with a pin f
which fits into a slot made in the bracket H fixed to the door D as shown. The
bracket C is vertically adjusted by means of a nut g and is secured to the door D by
means of the rod I which passes through the bracket C and door D as indicated.
The bars A B jointed together as described and connected to the door D and its
frame G as specified will support the door D and permit it to slide freely as the entire

page_text: weight of the door is carried on the pivot points described. The bars A B further
act as braces for the purpose of holding the door in proper line and prevent it from
binding or getting off its track.
When this hanger is applied to a wide door as shown in figure 2 the upper end of
the bar A is pivotted at 6 carried in a bracket attached to the door frame G while its
lower end is provided with a pin d as usual which fits into a slot made in the
bracket E. The upper end of the bar B is pivotted at e to an adjustable bracket
fixed to the door D while its lower end is provided with a pin ƒ which fits into a slot
made in the bracket H fixed to the door frame G. In other words the pivot points
which are connected to the door in figure 1 are connected to the door frame in
figure 2.
When the hanger is made as shown in figure 2 it is necessary that the bar A
shall be divided one half being placed below the bar B, and the other half above it,
the pivot pin a fitting into square holes in the two parts of the bar A while a round
hole is made in the bar B so as to permit it to move on its pivot. It will be noticed
that if the bar A were not divided as shown the said bars would not pass each
other as indicated in dotted lines, the full lines showing the position of the hanger
when the door is open, and the dotted lines showing their position when the door is
closed.
It should have been mentioned that the rod I is for the purpose of preventing the
door sagging as it is merely necessary to screw the rod I into the bracket C should
the door sag in the least either by shrinkage or undue weight.
Having now particularly described and ascertained the nature of the said invention,
as communicated to me by my foreign correspondent, and in what manner the same
is to be performed, I declare that what I claim is :-
1. A door hanger composed of bars A B pivotted together at a, one end of one of the
bars being pivotted to the door frame, and the opposite end of the other bar being
adjustably connected to the door frame, in combination with the door D, connected
by a pivot to one of the bars, and to the other bar by a connection which will permit
the vertical adjustment of the said bars, substantially as and for the purpose
specified.
2. A door D supported by the bars A B arranged as specified in combination with
the rod I substantially as and for the purpose specified.
