Improvement in the Manufacture of Swivel Joints or Bearings for
Swing Looking-glasses, Blind Rollers, and the like.
I, CHARLES DOUGLAS NORTON, of "Lamoni," Harcourt Road, Boscombe Park,
Bournemouth, in the County of Hampshire, Builder, do hereby declare the nature
of this invention to be as follows:-
My invention has for its object the production of metallic (or other suitable
material) swivel joints or bearings for swing looking-glasses for supporting the
frames of looking-glasses to the stand, pedestals or pillars which swivel joint there.
is great strength lightness and simplicity of construction. I will describe my,
invention as applied to a swing looking-glass, it being understood that the
description blind rollers. My method of forming or making the swivel joint or
bearing is as follows;-I take a piece of sheet steel, metal, brass, copper, iron, or
any other metallic substance, or any other suitable material for making the swivel
joint or bearing in two or more parts oval or round shape and somewhat larger
than the swivel joint is required. I then have pierced two or more holes across.
the blank as may be required, I then have formed round the edge or on one side
a ridge or angle by means of a stamp press machine or any other suitable method
forming a cup shape, the sides being bent to an angle forming a dovetail shape
on the half circle. I then have a smaller blank cut out of an oval or round shape,
I then have two or more holes pierced across the blank as may be required. I
then have the edges bent to an angular shape so as to fit inside the first cup shape
blank for the purpose of forming a swivel or movable joint and connecting the
frame of a swing looking-glass to the stand pedestals or pillars of the glass. The
larger part of the swivel is attached in a most effectual manner to the stand
pedestals or pillars by means of screws, nails, rivetts, cotters, pins or bolts and
nuts. The smaller part of swivel is attached by the same means as the larger part
but fixed to the frame of the swing glass then the frame is placed in between the
stand, pedestals or pillars and the smaller part of swivel joint fits into the larger
part, thus making a firm ridged swivel joint by which the swing glass can be
easily moved or adjusted to any angle or position and remain perfectly rigid in
the position placed. The glass can be taken out of the stand, pedestals or pillars
instantaneously thus saving considerable waste of time over and above the pre-
sent method adopted in swing looking glasses.

CHARLES DOUGLAS NORTON, of "Lamoni," Harcourt Road, Boscombe Park,
Bournemouth, Hampshire, letired Builder, 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:.
Improvements in swivel joints or bearings for mounting looking glasses window
blind rollers and for analogous purposes of which the following is a full and
complete specification such as will enable those skilled in the art to which it
appertains to make and use the same.
This invention relates to swivel joints or bearings such as are adapted to be
used for swinging looking glasses the rollers of window blinds and for analogous
purposes and it has for its object to provide a simple and improved device of this
character which will be inexpensive in construction and which can be con-
veniently applied in operative position.
The invention is fully disclosed in the following specification of which the
accompaning drawing forms a part, in which the separate parts of my improve-
ment are designated by the same letters of reference in each of the views and in
which: :―
Fig. 1 is an elevation, partly in section showing a looking glass mounted
upon a frame or pedestal by means of my improved swivel joints or bearings.
Fig. 2 is a detail perspective view of the cup-shaped member of the joint
device and
Fig. 3 is a detail perspective view of the socket member of the joint device.
My invention is herein illustrated as applied to a swinging looking glass, and
is described in this relation, but it will be understood that it may be employed
for divers purposes and in any position or relation to which it is adapted.
In carrying out my invention blanks of a circular shape are first cut from a
plate or piece of sheet steel brass, copper, iron, or any suitable or adapted material,
the blank being somewhat larger in diameter or dimensions than the joint
member which is to be formed therefrom.
Two or more perforations are then pierced in said blank, and the edge of the
same at one side is bent up by means of any suitable stamping or pressing
machine or other method to form a flange extending around one side of the base
portion this flange being cup-shape so that it forms a dove-tail contour in cross
section.
A similar smaller blank of circular or round shape is cut from a sheet metal
plate and similarly pierced with perforations, when the edges are bent up to form
a curved or cup-shaped circumferential flange adapted to fit within the similar
flange on the base member and dove-tail therewith, the inner member being
adapted to have a swivel or rotary motion with respect to the base member, when
the members are respectively connected to the looking glass frame and the stand
or pedestal therefor by means of screws or in any other suitable manner.
preference the larger or base member is secured in fixed position, and the smaller
or inner member is secured to the movable object and by means of the improved
construction and arrangement in which one member fits and turns within the
By

adjustment of the movable object in position at any desired angle.
I will now proceed to describe my invention more specifically with relation to
its structural details and referring to the drawings.

A designates the pedestal or stand having the posts or uprights a a.
nates the looking glass which comprises the frame bb. C. designates the base
or larger member of the swivel joints which comprises the circular base plate or
disc having perforations or openings cc through which securing screws
adapted to be passed, and carrying the projecting curved or angular flange c2
extending part way round its circumference and adapted to form a dove-tail con-
nection, as shown. The flange c2 preferably extends half way around the cir-
cumference of the base plate. The member C is secured to the inner face of the
posts or uprights a a.
D designates the smaller or inner member of the swivel joint which comprises
a base plate or disc having openings or perforations dd through which securing
screws are adapted to be passed, and the edge of said plate is surrounded by a
circumferential projecting curved or angular flange d2 which is adapted to form
a dove-tail connection with the base member C. The member D is secured to
the edges of the frame bb of the looking glass.
It will be understood that the circumferential flange of the member D is
received within the part 2 circumferential flange of the member C so that the
smaller or inner member is adapted to be turned within the larger or base
member, and the engagement of the respective flanges is such that they will
impinge at any point of adjustment and thus retain the looking glass or other
movable object in any position to which it is set, and at the same time the swivel
joint may be readily and conveniently operated to adjust or change the position
of the looking glass or movable object. To provide for the separation or discon-
nection of the members of the swivel joint; the base plate c2 of the member C is
provided at the centre of the edge of its open side opposite the flange with a project-
ing lip or point c3 and a corresponding notch or recess d3 is provided in the edge
of the flange d2 of the member D. This construction enables the member 1) to
be slid laterally within the member C but the former will always be locked in
connection with the latter at every point of its operation except at the one point
where the recess or notch d3 registers with the lip or projection c3.
Having fully described my invention I claim as new and desire to secure by
Letters Patent:―

mately relatively cup-shaped and the flange of the inner or movable member
being received by the corresponding flange of the base member, substantially as
and for the purpose set forth.

projecting part way around its circumference, said base member being also pro-
vided with a lip or projection at its edge opposite said flange and an inner or
movable member embodying the plate or disc and having a circumferential
