principal office at No. 45, Broadway, in the City of New York, State of New
York, United States of America.]
I, PHILIP ARTHUR NEWTON, of The Office for Patents, 6, Bream's Buildings,
Chancery Lane, in the County of London, Patent Agent, 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:.
This invention relates to a chain link, with the object in view of providing a link
of such structure that it may be formed from a sheet of metal by stamping or
swaging, and having bearing cars or projections formed integral with its sides,
and extended in planes at an angle to said sides.
The bearing ears or projections, which are formed integral with the sides, may
be located at the free ends of the sides, for the reception of a cross pin, or at a
distance back from the ends of the sides, for the attachment of a cross slat or
bucket, or they may be formed both at the ends, and at a distance back from the
ends, as occasion may require.
In the accompanying drawings,
Fig. 1 is a plan view of a link provided with bearing ears or projections formed
both at the extremities of its sides and at a distance back from the extremities;
Fig. 2 is a view of the same in side elevation;
Fig. 3 is a view of the same in end elevation ;
Fig. 4 is a plan view of a link, in which the sides are provided with bearing
ears at a distance back from their ends only;
Fig. 5 is a view of the same in side elevation;
Fig. 6 is a view of the same in end elevation,
Fig. 7 is a plan view of a link, showing the bearing ears for the cross slat or
bucket turned in a plane at right angles to those shown in Figs. 1 to 6, inclusive ;'
Fig. 8 is a view of the same in side elevation ;
Fig. 9 is a view of the same in end elevation;
Figs. 10, 11, 12, 13, 14, and 15, represent views of a modified form, in which
the support for the cross slat or bucket is made independently of the sides of the
link, and clamped thereto;
Figs. 16, 17, 18, 19, and 20, represent views of a modified form of slat or bucket
support clamped to the sides of the link; and
Figs. 21, 22, 23, and 24, represent views of still another modified form of slat
or bucket support clamped to one side only of the link.
The sides of the link, in Fig. 1, are denoted by A. They are connected at one

page_text: At
end, by an open hook portion B, of well-known or approved form, the portion B
being an integral part of the sheet of metal from which the sides A are cut.
their opposite or free ends, the sides A terminate in bearing ears or projections a, a¹,
formed by twisting the ends of the sides A a quarter turn, thereby causing the ears
or projections a, a, to assume a position at right angles to the plane of the sides A.
The ears a, a, are provided with perforations a², through which a cross pin C
extends, the cross pin being conveniently locked in its position by means of a
key c. On the cross pin C, a sleeve 1) is supported, the sleeve D serving to space
the free ends of the sides A of the link apart, and at the same time forming the
bearing pivot for the adjacent link, not shown.
The sleeve D is held in fixed position by means of a nose ³ struck inwardly
from the wall of the perforation a², through one of the ears, into a notch a* in
the end of the sleeve.
The sides A are further provided, at a distance from their free ends, with bearing
ears or projections b, 61, which are turned into a plane transverse to the plane of
the sides A, by first turning their neck portions 62 at an angle to the plane of
the sides, and then further twisting the necks of the ears, to bring the ears b, b¹,
into a plane at an angle to the plane of the necks 62. The ears b, b', are provided
with perforations 63 for the reception of a suitable fastening device, of any well-
known or approved form, for securing, to the ears, a cross slat or bucket, according
to the purpose for which the chain is to be used.
The ears b, b, are an integral part of the sides A of the link, so that the structure,
exclusive of the cross pin C and bearing sleeve for connecting the link to an
adjacent link, may be stamped from a single sheet of steel or other suitable metal,
and, by further manipulation, developed into the completed form represented in
Fig. 1, 2, and 3.
In the form shown in Figs 4, 5, and 6, the sides A¹ of the link are connected, at
one end, by an open hook portion B, and at the opposite end by a cross bar B¹
the parts B, B1, being both formed integral with the side bars A2, the cars a, a³,
for the reception of the cross pin being, in this instance, omitted, and the perforated
cars b, b, for the reception of the cross slat or bucket, being formed in all respects
. similar to those shown in Fig. 1, 2, and 3, hereinabove referred to.
In the form shown in Figs. 7, 8, and 9, the sides A² of the link are connected
by the open hook B at one end, by the cross bar B1 at the opposite end, and the
ears c, c¹, for the reception of the cross slat or bucket, are offset from, and turned
into, a plane parallel with the plane of the sides a², the final twist, which in the
forms hereinabove referred to turn the slat or bucket supporting ears into a plane
transverse to the plane of the link, being, in this instance, omitted.
In Figs. 10 to 15, inclusive, the support for the cross slat or bucket is denoted
by C, and is faced to receive the cross slat or bucket in the plane of the body of
the link, its opposite edges being articulated, and certain of the articulations bent
around the sides of the link in one direction, and other articulations extended in
opposite directions into engagement with the face of the side of the link. In
this instance, in order to prevent the support C from shifting its position either
longitudinally or laterally of the link, it is found desirable to provide the inner
face of the side of the link with a recess a³, and extend the middle articulation
of the three prongs or articulations shown in the said recess, while the remaining
prongs or articulations 2, 4, are bent around the remaining three faces of each
of the sides.
The support C, in Figs. 16 to 20, inclusive, is secured to the opposite sides of
the link in a manner quite similar to that shown in Figs. 10 to 15, inclusive, but
the face of the support C¹ is turned into a plane transverse to the plane of the body
of the link.
In Figs. 21 to 24, inclusive, the slat or bucket support C2 is faced away from the
side of the link, and is secured by a clip 1 to the sides of the link, the face of
the branches of the clip being turned over on the face of the support, as shown
at dd

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
from abroad, I declare that what I claim is :-
-
1. A chain link formed of sheet metal, and having its sides provided with ears
turned at an angle thereto, in combination with a cross pin supported by said ears,
for connecting the link with an adjacent link, substantially as set forth.
2. A chain link formed of sheet metal, and having ears projected from its sides,
for securing a cross slat or bucket to the link, and means for connecting the
opposite ends of the link with adjacent links, substantially as set forth.
3. A chain link formed of sheet metal, and having its sides provided with
supporting ears at their ends, and at a distance back from their ends, the said ears
being integral with the sides of the link, and means for connecting the bearing
cars at the ends of the sides with an adjacent link, substantially as set forth.
4. A chain link formed of sheet metal, and having perforated bearing ears at
the extremities of its sides, a cross pin adapted to engage said ears, and a spacing
and bearing sleeve supported on the cross pin, the said sleeve and ear at the end
of the sleeve being provided, the one with a recess, and the other with a projection
adapted to enter the recess, to lock the sleeve against a rotary movement, sub-
stantially as set forth.
5. A chain link combined with a support for a slat or bucket, in which the slat
or bucket support is formed independently of the link, and secured to one or both
of the opposite sides of the link, substantially as set forth.
