Improvements in "Fournisseurs for Circular Hosiery Looms.

Loonis.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, in the County of Lancaster, and
323, High Holborn, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of this invention to be as follows:-
"
The object of the present invention is to effect the working of the "fournisseur
of circular hosiery looms in a more secure and simple manner than has been done
hitherto, and to obtain besides a quieter and more uniform working. These results
are mainly secured by avoiding the use of the usual train of wheels and the consequent
loss of power attendant upon the friction these develope.
The toothed wheel which acts as a driver in the well known "fournisseur," does
not in these improvements engage (eingreift) the needles as is usual, but the toothed
crown or rack of the circular loom, that is to say, when the loom and consequently
the toothed rack is in motion, the toothed driving wheel begins to revolve with it.
The driving wheel is provided either with pins projecting from its surface so as to
form teeth, or with the inside teeth into which a toothed pinion on a second axis,
gears. A toothed wheel on the same axis and firmly connected with the pinion,
transmits through another toothed pinion on a third axis, the motion to the
"fournisseur" working in the well known manner. The driving wheel and its pinion
are carried in a secure manner by means of a nave and socket. To obtain a different
speed of rotation, the pinion which gears into the driving wheel can be changed,
and one of a different diameter inserted. For this purpose the driving wheel can be
adjusted as regards the distance of its centre from the centre of the pinion by means
of a slot provided in the frame, and fixed by means of a screw.
By the arrangement of the driving wheel and its pinion connected with the wheels
heretofore described, a device working safely and quietly for driving the "fournisseur"
is obtained in a simple and practical manner. By changing the aforesaid pinion a
different speed of rotation is conveniently produced, which could not. hitherto be done
without requiring lengthy manipulations, and entailing a great loss of time.

Improvements in Fournisseurs" for Circular Hosiery Looms.
A communication from abroad by Wilhelm HeideLMANN, of No. 1, Hauptstrasse,
Stuttgart, in the Empire of Germany, Manufacturer of Circular Hosiery
Looms.
1, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, in the County of Lancaster, and
323, High Holborn, in the County of Middlesex, Civil Engineer 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 :-
"
The object of the present invention is to effect the working of the "fournisseur
of circular hosiery looms in a more secure and simple manner than has been done
hitherto, and to obtain besides a quieter and more uniform working. These results
are mainly secured by avoiding the use of the usual train of wheels, and the
consequent loss of power attendant upon the friction these develop.
In the drawing,
Figure 1 is a section of the improved apparatus on line x-x, Figure 2.
Figure 2 a side view of same.
Figures 3 and 4 show details hereinafter explained.
The toothed wheel A which acts as a driver in the well known "fournisseur," does
not in these improvements engage the needles N as is usual, but the toothed crown
or rack of the circular loom, that is to say, when the loom and consequently the
toothed rack D is in motion, the toothed driving wheel A begins to revolve with it.
The driving wheel A is provided either with pins C, C, projecting from its surface
so as to form teeth (as in Figures 1 and 2), or with an internally toothed wheel K,
Figure 3, into which gears a toothed pinion B mounted on a separate axis. A toothed
wheel Jon the same axis, and firmly connected with the pinion B, transmits the
motion to the fournisseur" F through another toothed pinion L working in the
well known manner. The driving wheel A and its pinion B are carried in a secure
manner by means of a nave H, and a socket H'. To obtain a different speed of
rotation, the pinion B can be changed, and one of a different diameter inserted. For
this purpose the driving wheel A can be adjusted as regards the distance of its centre
from the centre of the pinion B, by means of a slot & provided in the bracket E,
and it can then be fixed by means of a screw S (see Figure 4).
By this arrangement of the driving wheel A, and its pinion B connected with the
wheels J and L, a safe and quietly working driving device for the "fournisseur" is
obtained in a simple and practical manner. By changing the aforesaid pinion B, a
different speed of rotation is conveniently produced, which could not hitherto be done
without necessitating lengthy manipulations, and entailing a great loss of time.

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
by my foreign correspondent, I declare that what I claim is :-
In a "fournisseur" for circular hosiery looms, a driving gear consisting essentially
of a toothed wheel A provided with pins C, C, or with an internally toothed wheel K,
and capable of being adjusted and connected with wheels J and L through a change
wheel B, substantially as described.
