PROVISIONAL SPECIFICATION.
Improvements in Runners or Suspension Apparatus for Sliding
Doors, Gates, and the like, Especially Applicable for Cabinets.
We, FRED BURROWS HOGARTHI, Joiner, Hoylake, and HENRY DAUDENEY
BRANDRETH, Patent Medicine Proprietor, Hoylake, both in the County of Chester,
do hereby declare the nature of this invention to be as follows:-
The arrangement usually adopted with sliding doors is to provide them with
pulleys or wheels running on a rail on the bottom or the top or both. This besides
being more expensive than our plan is very liable to get out of order.
Now by our invention we suspend the door from above entirely by sliding
contact. To the top of the door and to the top of the cabinet respectively we attach
an shaped strip of metal and a somewhat similar strip but with a continuation
horizontal and then upward again so as to form a groove. These two hook one into
the other and are screwed the one to the top of the door, the other to the upper part
of the cal inet. The result is that the door hangs entirely by means of the projection
of the slide in the groove made to fit one of these two strips extends the whole
length. The other can be two or more short pieces. With large hoavy gates the one
is preferably of polished brass, bronze or cast iron and the other smooth wrought iron
or steel and the groove is in such cases the continuous stationary support and is
supplied with a lubricant, either grease plumbago or the like, the dipping down into
it. In light doors, however, the reverse arrangement can be used if desirable,
the continues the flange and the groove piece in two or more short pieces running
upon it.

COMPLETE SPECIFICATION.
Improvements in Runners or Suspension Apparatus for Sliding
Doors, Gates, and the like, Especially Applicable for Cabinets.
We FRED BURROWS HOGARTH, Joiner, Hoylake, and, HENRY DAUBENEY
BRANDRETH, Patent Medicine Proprietor, Hoylake, both in the County of Chester,
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 arrangement usually adopted with sliding doors is to provide them with
pulleys or wheels running on a rail on the bottom or the top or both. This, besides
being more expensive than our plan, is very liable to get out of order.
Now by our invention we suspend the door from above entirely by sliding contact.
It is illustrated in the accompanying drawing in which
Figure is a cross section of the apparatus,
Figure 2 a modification.
A is the upper part of a sliding door, B. the top board of the door frame, C is an
Lshaped strip of metal attached to the door by screw D, Ga projection therefrom
forming a hook shown only in Figure 1. E is a hooked shaped strip attached to the
upper part of cabinet or door frame by screw F and baving in Figure 1 a re-entering
projection H. Figure 2 shows a simpler and cheaper form of the apparatus.
For cabinet work we prefer to make both parts C and E of brass, E continuous
along the whole length on which the door runs, but can be either continuous
the entire length of the door or only two or more short pieces at intervals (of the
[Price bid 1

page_text: section shown). For large outdoor structures the part E is usually of strong cast
iron, wrought iron or steel; the part C of brass, bronze or malleable cast iron and
the parts well lubricated with graphite grease or other lubricant. When the invention
is used for drawers, the part C is fixed to the chest or cabinet in which the drawer
slides and the part E to the drawer, both being continuous for the length of the
drawer or nearly so. For this purpose the design of brass-work, Figure 1, is much
better than that of Figure 2, as the projecting piece at the end of the shaped piece
in Figure 1 takes both upward and downward pressure from the wood work.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved runners or suspension apparatus for sliding doors and other objects
formed of a hooked or downwardly pointing blade (or sliding piece with smooth sliding
surface) attached to the suspended article preferably near the top and a smooth surfaced
trough or supporting slide on the frame or other stationary part supporting said blade
or sliding piece substantially as described.
