PROVISIONAL SPECIFICATION.
Improvements in Knitting Machines.
JAMES HIGHAM 127 Stretford Road Hulme Manchester Manager do hereby
declare the nature of this invention to be as follows:-
Improved bearings in rails for knitting machines in or on which the cam plates
or short carriages slide to prevent the cam plates or carriages from lifting &
rocking as is generally or usually the case with short cam plates or carriage
machines, also improved method of connecting the short cam plates or carriages
together.
or
These bearings are formed by grooving and tonguing the rails in a vertical &
horizontal direction the short cam plates or carriages being correspondingly fitted
to slide in same.
To connect the short cam plates or carriages together I use a bolt passing
through bearings upon the short cam plates or carriages.

COMPLETE SPECIFICATION.
Improvements in Knitting Machines.
I, JAMES HIGHAM of 127 Stretford Road, Hulme, Manchester, in the County
of Lancaster, Manager, 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 the bearings in rails in knitting machines, in or on
which the cam plates or short carriages slide, and also to the means for uniting
said cam plates or carriages. The objects of this invention are to prevent the cam
carriages from lifting or rocking which occurs to a greater or less extent in
machines of the ordinary construction when working, and to permit the cam
carriages to be disconnected if either of said carriages requires to be removed for
any purpose.
I attain these objects by the means hereinafter described and as illustrated in the
accompanying sheet of drawings, in which
Fig. 1 is a plan view of a parallel bed knitting machine with my invention
applied;
Fig. 2 is a sectional view of the same through line A. A.
Figs. 3 and 4 are longitudinal and sectional views drawn to an enlarged scale, of
the rails upon or in which the cam carriages slide.
In these views similar letters refer to similar parts.
In this invention, I construct the rails with grooves c and d formed therein
as in Fig. 4, said grooves being arranged so that each groove may be planed
and finished true without requiring the rail to be built up or constructed of two
or more parts in order to obtain access to either of the grooves for this purpose.
1 construct the lower edges e¹ of the cam carriages e or other moving parts that
fit in said rails, of a shape corresponding to the form of the aforesaid grooves c
and d as shown in Fig. 2.

page_text: By these means, the effects of vertical and horizontal thrusts are neutralized,
and the cam carriages may be worked either quickly or slowly with perfect
⚫steadiness.
I connect the cam carriages e on each side of the machine, by constructing said
cam carriages with a boss as g, through which to pass a bolt h, the intermediate
space being preferably filled with a ferrule as j.
By these means the cam carriages are rigidly connected but may be readily
.disconnected.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
:
1st. In the rails of knitting machines on or in which the cam carriages slide,
the construction of said rails with grooves as c and d for the purpose and in the
manner substantially as herein before described and as shown in Fig. 4 on the
drawings.
2nd. In knitting machines, the use of a bolt as passing through a boss as g
formed on or attached to the cam carriage, for connecting said cam carriages in the
.manner substantially as herein before described.
Dated this 15th day of May 1894.
