AN IMPROVED CORD HOLDER FOR GRAIN BINDERS
Year: 1885

page_text: I GEORGE FREDERICK REDFERN of the General Patent Office, N° 4, South
Street, Finsbury, in the County of Middlesex, Patent Agent, do hereby declare
the nature of the said invention for "AN IMPROVED CORD HOLDER FOR GRAIN
BINDERS a commuication from abroad by Byron Eugene Huntley, of Brockport,
State of New York, United States of America, Manufacturer, to be as follows:-
"
The invention communicated to me relates to cord holders for grain binders, and
it consists of the devices and combination of devices hereinafter described.
The objects of the invention are to provide simple and effective means for
positively operating the cord clamping disc, and retaining it in place, and to reduce
friction by dispensing with a number of parts heretofore used in connection with
cord holding-devices.
A cast-iron frame carries the knotter, the holder, and co-operating parts; a
breast plate is secured to the said frame. On the knotter-driving-shaft is a cam
and gear wheel provided with a segment gear which at the proper time meshes,
with the pinion of the knotter for driving the latter; a notched clamping-disc
is pivoted on a plate, and a grooved holding-jaw co-operates with the disc to hold
the cord.
The jaw is pivoted to the frame and is pressed towards the said disc by a
spring. So far the construction is well known in the "Appleby" type of machines.
According to these improvements the clamping disc is provided with a pinion;
two gear wheels mesh together, and one of the gear wheels meshes with the
pinion of the clamping disc. The other gear wheel is partly rotated at the proper
time to actuate the wheel meshing with the pinion, and the clamping disc by the
following means; a plate or disc is provided secured to the knotter-driving-shaft ;
a cam-disc-wheel is mounted loosely on the said shaft and is adjustably secured to
the said plate by means of bolts passing through the latter plate, and through slots
in the cam disc wheel. These bolts are provided with nuts whereby the plate and
wheel may be clamped together in different relative positions. This adjustable
feature is for a purpose hereinafter described. On the side of the cam disc wheel
at its periphery is formed a rib or flange. This rib is not continuous, but is divided

page_text: at one place, and its end portions lap by each other with a space between them
equal to the thickness of one of the teeth of one of the herein before described gear
wheels. For the greater portion of its length the rib is concentric with the wheel,
but its end portions are eccentric therewith, one of the portions being brought
nearer the centre. The rib thus forms a helical or scroll like cam.
The thickness of the rib corresponds with the space between the adjacent teeth
of the said gear-wheel, with which wheel the said rib is always engaged.
By this means, when, by the rotation of the cam-wheel, the eccentric portions
of the rib become engaged with the gear-wheel, the latter will be partly rotated
and, by means of the other gear-wheel and the pinion, the clamping disc will be
moved the distance from one notch to the next for each revolution of the cam-
wheel, and while the concentric portion of the said rib is engaged, the gear wheels
and consequently the clamping disc will be retained in a fixed position.
The adjustable feature of the scroll-cam above described is for the purpose of
taking up wear of the parts, and adjusting the movement of the clamping disc.

page_text: I, GEORGE FREDERICK REDFERN, of the General Patent Office, N° 4, South
Street, Finsbury, in the County of Middlesex, Patent Agent, do hereby declare the
nature of this Invention (a communication from abroad by Byron Eugene Huntley,
of Brockport, State of New York, United States of America, Manufacturer) 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 Cord holders for Grain Binders, and it consists of the
devices and combination of devices hereinafter described.
The objects of this invention are to provide a simple and effective means for
positively operating the cord clamping disk, and retaining it in place, and to reduce
friction by dispensing with a number of parts heretofore used in connection with
cord-holding devices.
In order to enable the invention to be fully understood, I will describe the same
by reference to the accompanying drawing, in which figure 1 is an inverted plan
or outer side-view of a portion of a Grain-Binder, showing these improvements
applied thereto: figure 2 is a plan or inner side-view of the same, partly in section;
and figure 3 is an elevation of part of the mechanism. Similar letters refer to
similar parts in all the figures.
As the improvement relates only to the manner of operating the cord clamping
disk a description of the other portions of the binding mechanism will not be
necessary; further than to indicate some of the co-operating parts.
B is a cast iron frame carrying the knotter, the holder and co-operating parts;
C, is a breast plate secured to the said frame; E, is the knotter-driving shaft; A is
a cam and gear wheel fixed on the said shaft, and provided with a segment gear
which, at the proper time, meshes with the pinions a of the knotter for driving the
latter; G, is a notched clamping-disk pivoted on a plate I, H, is a grooved holding
jaw co-operating with the disk G, to hold the cord.
The jaw is pivoted to the frame, and is pressed towards the said disk, by a
spring h. So far the construction is well known in the "Appleby" type of
machines.
According to these improvements the clamping disk G, is provided with a
pinion g.
F, F, are gear wheels, meshing together, the former also meshing with the
pinion g of the clamping disk.
The wheel F¹, is partly rotated at the proper time to actuate the wheel F, and
the clamping disk by the following means. D¹, is a plate, or disk, secured to the
knotter-driving shaft E; D, is a cam disk wheel shewn detached in elevation at
figure 3, mounted loosely on the said shaft, and is adjustably secured to the
plate D¹, by means of bolts K passing through the latter plate, and through
slots K¹, in the wheel D.
These bolts are provided with nuts whereby the plate and wheel may be clamped
together in different relative positions.

page_text: This adjustable feature is for a purpose hereinafter described. On the side of
the wheel D, at its periphery, is formed a rib, or flange d. This rib is not con-
tinuous, but is divided at one place, and its end portions dd, lap by each other
as shown, with a space between them equal to the thickness of one of the teeth on
the wheel F, For the greater portion of its length, the rib is concentric with
the wheel, but its end portions are eccentric therewith, the portion d³, being
brought nearer the centre. The rib thus forms a helical, or scroll-like cam.
The thickness of the rib corresponds with the space between the adjacent teeth
of the gear-wheel F¹, with which wheel the said rib is always engaged.
By this means, when, by the rotation of the cam-wheel D, the eccentric portion d'
of the rib becomes engaged with the gear-wheel, the latter will be partly rotated,
and, by means of the wheel F and pinion g the clamping disk G, will be moved
the distance from one notch to the next for each revolution of the cam wheel D,
and while the concentric portion of the said rib is engaged, the gear wheels, and
consequently the clamping disk will be retained in a fixed position.
The adjustable feature of the scroll-cam, above described, is for the purpose of
taking up wear of the parts and adjusting the movement of the clamping-disk.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
:
1. In a grain-binder, the combination of the notched clamping disk G, provided
with the pinion g, the wheel D, provided with the rib, or scroll cam d, and the
gear wheels F, F, substantially as, and for the purpose hereinbefore described and
represented in the accompanying drawing.
2. In combination with the notched clamping-disk and intermediate gear-wheels,
the wheel D, having the scroll-like rib d, as described whereby the said disk is
moved one notch for each revolution of the said wheel D, and is there retained in
position substantially as herein before described and represented in the accompanying
drawing.
3. In combination with the clamping disk and gear wheels, the plate D₁, the
ribbed wheel or scroll cam plate D, having the slots K¹, and the securing bolts K,
substantially as and for the purpose hereinbefore described and represented in the
accompanying drawing.
4. The improved Cord holder for grain' binders herein before described and
represented in the accompanying drawing.
