page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex, for an
Invention of IMPROVEMENTS IN BALL AND SOCKET JOINTS A communi-
cation to him from abroad by Otis Converse White, of the State of Massa-
chusetts, United States of America.
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 23rd June 1882.
HERBERT JOHN HADDAN, of Kensington, Middlesex. "IMPROVEMENTS IN BALL
AND SOCKET JOINTS a communication to me from abroad by Otis Converse
White, of the State of Massachusetts, United States of America.
The improved ball and socket joint constituting the Invention is to give support
to and allow to slide lengthwise or to revolve or be turned laterally in various
directions, a rod arranged within and going through the ball-such ball being bored
diametrically to receive the rod and constructed in sections or made contractile to
admit of its being clamped on the rod. The socket or socket piece for holding the
ball is also contractile, and provided with means of contracting it upon the ball in
order to compress it or its sections on the rod. Furthermore, the socket is provided
with conical or flaring mouths, to allow of lateral movements of the rod.
The Invention consists more particularly
1. In the combination of the ball made contractile or in sections, with a
contractile socket piece provided with means of contracting or clamping it upon
the ball
2. In the ball contractile or made in sections and perforated diametrically, in
combination with the slide rod, extended through the ball and with the contractile
socket piece provided with means of contracting or clamping it on the ball.
3. In the ball socket provided with annular or belt shaped bearings to rest
against the ball and with an intervening annular space to be out of contact with
the ball.
4. In the ball contractile or made in sections and perforated diametrically to
receive the slide rod, in combination with the socket piece socketed to receive the
Ball

by the said Herbert John Haddan in the Great Seal Patent Office on the
23rd December 1882.
HERBERT JOHN HADDAN, of Kensington Middlesex. IMPROVEMENTS IN BALL
AND SOCKET JOINTS, a communication to me from abroad by Otis Converse
White, of the State of Massachusetts, United States of America.
In the accompanying drawings, which illustrate this Invention Fig 1 is a top
view. Fig 2 an end elevation. Fig 3 a side elovation. Fig 4 a transverse section,
and Fig 5 a horizontal section of one construction of a joint of the improved kind
with its slide bar. Fig G is a side view, and Fig 7 a longitudinal section of a joint
somewhat differently constructed but embracing this Invention, the nature of which
is defined in the claim or claims horeinafter presented.
This ball and socket joint is to give support to and allow to slide lengthwise or
to revolve, or be turned laterally in various directions, a rod arranged within and
going through the ball, such ball being bored diametrically to receive the rod and
constructed in sections or made contractile to admit of its being clamped on the
rod. The socket or socket piece for holding the ball is also contractile and
provided with means of contracting it upon the ball in order to compress it or its
sections on the rod. Furthermore the socket is provided with conical or flaring
mouths, to allow of lateral movements of the rod.
In the drawings, A denotes the slide rod, B the ball, and C its socket piece. The
rod AI usually make cylindrical, but it may be prismatic. It goes through the ball
diametrically thereof, which is properly perforated or bored to receive it. Besides
having the bore a, the ball is made in separate pieces or sections b, which extend
about the rod, and are arranged within a chamber c, of the socket piece C, such
chamber being spherical or of other proper form and provided with two conical or
flaring mouths de, arranged with it as represented. The socket piece is split
transversely or made in separate parts fand g.
In Figs 1 to 5, the said parts ƒ and g are represented as having flanges h, and
connected by screws i going through one flange and screwed into the other. The
part is also shown as having a portion of it projecting down from it into a
supporting stand from which the part g extends. Across and fastened to the
stand is a cap m, provided with a cammed lever n, which on being turned one way
within the cap acts against the portion , so as to force the socketed part toward
the socketed part g in order to contract the ball upon the rod. On the cammed
lever being turned the opposite way, the ball will be free to turn within its socket,.
in various directions, and the rod be free to be revolved on its axis, or to be turned
laterally with the ball in the socket, or to be slid lengthwise within the ball.
In Figs 6 and 7 the socketed piece, is represented as made in two parts f. g.
connected by two screws o. p, and a thumb nut 9 screwed upon one of them. The
screw o goes through the larger part fand screws into the lesser part g, while tho
screw ? goes through and has its head inserted in the lesser part. Its shank goes
through the larger part, and has the nut screwed on it the said shank.
Instead of making the socket to bear on its centre surface against the ball
sections, I usually so construct the socket, that each separate portion of it shall
have a narrow annular bearing or belt only to bear upon the ring sections. This
bearing is shown at 8 s in Figs 4 and 7.
By so constructing the bearings of the socket, advantage is obtained, as the
annular space t, between the annular bearing surfaces, will answer to hold oil or a
lubricating matter, and the clamping parts will act with better effect on the ball.

page_text: CLAIMS:
1. The combination of the ball made contractile or in sections, with a contractile
socket piece provided with means of contracting or clamping it upon the ball.
2. The ball contractile or made in sections and perforated diametrically, in
combination with the slide rod extended through the ball, and with the contractile
socket piece provided with means of contracting or clamping it on the ball.
3. The ball socket provided with annular or belt shaped bearings to rest against
the ball and with an intervening annular space to be out of contact with the ball.
4. The ball contractile or made in sections and perforated diametrically to
receive the slide rod, in combination with the socket piece socketed to receive the
ball and having to the socket flaring mouths.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this twenty-third day of December, A.D. 1882.
