[Com-
This Invention consists mainly in a combination of parts forming a support to be
fixed in a wall or ceiling to serve as a means of fixation for coat hooks, hat pegs,
curtain holders or brackets, hangers for various purposes, wall brackets, gas arins or
brackets, pendants, suspensions, chandeliers, and other objects to be fixed to the
walls or suspended from the ceilings of houses, the object of the Invention being to
dispense with the wood blocks generally employed for fixing such objects to, or
other means of fixation.
In driving nails into a wall they are apt to be bent on meeting the brickwork or
masonry and fail to penetrate properly, whilst in plaster or cement, although they
enter freely, they obtain no hold and are easily pulled out. To obviate this it has
been usual to insert wood blocks in the brick work for nailing or screwing such
objects to, or to seal or bed fastenings of other descriptions with plaster or cement.
These means have the serious objection that the surfaces of the walls, &c, whether
papered or painted, are damaged and rendered unsightly for some distance around.
These disadvantages are entirely obviated by this Invention, it being merely
necessary to bure a clean cylindrical hole in the wall or other structure of the proper
depth and diameter to receive the means of fixation of this Invention, no damage
whatever being done to the surrounding portions.
The means of fixation consist of an expanding plug adapted to be wedged tightly
in the hole and constructed of two, three, or four segments of a cylinder having an
internal cavity of conical or wedge shape traversed by a screwed rod having a nut

page_text: upon it which has its sides inclined to correspond to inclined inner surfaces of the
segments whereby, when the screw is turned the nut is caused to travel along and
expand the segments slightly so as to jam them tightly against the sides of
the hole in which the expanding plug is placed and thus wedge it firmly in position.
The screw rod has a head or shoulder which prevents it having any longitudinal
motion, and upon its front end may be formed or fixed either permanently or
detachably the peg, hook, bracket, or other article to be supported. A suitable rose
or back plate is fixed upon the plug to cover the margin of the hole and conceal
any slight damage in the immediate vicinity.
According to one form the segments, three in number, form when collapsed
together a complete_cylindrical plug having a through conical cavity, the base of
the cone being at the inner or rear end of the plug; at the front end the segments
fit close around the screw rod and are held together by passing through a central
hole in the rose or back plate, the edges of which hole engage in a circumferential
groove in the segments. Upon the scrow is a nut coned to correspond to the cavity
within the segments and which is prevented from turning with the screw by wings
formed upon it entering the longitudinal divisions between the segments. The
screw rod has a head or shoulder which bears against segments or against the rose
or back plate so as to press the latter firmly against the wall. This plate may be
adapted to have affixed or applied thereto the hook, bracket, or other article, or the
latter may be in one with, or be screwed or otherwise attached to a prolongation of
the screw rod.
A modification of the above plug is composed of two or more segments not
separate as before but formed in one at their front end with a cylindrical portion,
the segments having sufficient flexibility at the point of junction there with to permit
the expansion of the plug. The inner surfaces of the segments are inclined in tho
opposite direction to the previous case, and may have external lugs or hook like
projections at the inner or rear ends to be forced or embedded-in the sides of the
hole. The screw rod passes through a hole in the cylindrical front end of the plug
and has a shoulder upon it which bears against the inside of such cylindrical
portion to take the outward thrust upon the screw rod in forcing the nut inwards
in this case instead of drawing it outwards as in the previous case to expand the
plug. The front end of the screw rod projects through the end of the plug and
through the rose or back-plate which is screwed thereto and said front end may be
squared for the application of a key to turn it, or the front end of the rod may be
prolonged and screwthreaded for fixing the peg, bracket, or other article thereto, or
the latter may be fixed to a head on the screw rod or to the rose or back plate as
before described.
