1, BENJAMIN HAGUE of Roden Street Robin Hood Street, in the Town and County
of the Town of Nottingham Hosiery Machine Builder do hereby declare the nature
of this invention to be as follows:-
My Invention consists in providing a new means for effecting the racking of the
cylinder, or that part which carries the goods to be seamed.
In carrying my Invention into effect I fix ou the end of the back shaft of such
machine a small toothed wheel, which is made to gear with another supported in a
suitable bracket; This second toothed wheel is also provided with a crank pin, which
takes one end of the lever used for racking the cylinder, the opposite end terminating
in the shape of a clawker or pawl: the said lever is provided with a guide and
suitable spring for bringing the same down. By this means I am enabled to run such.
machines at a greater speed than heretofore, where the said pawl or clawker was
caused to rise by means of a weighted lever operated by a cam, such motion being
uncertain at high speeds.

COMPLETE SPECIFICATION.
Improvements in Machines Commonly known as Point Seaming
Machines.
1, BENJAMIN HAGUE of Coopers Factory Roden Street, Robin Hood Street in
the Town and County of the Town of Nottingham Machine Builder 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:-
My Invention consists in providing a new means for effecting the racking of the
cylinder or that part which carries the goods to be seamed.
In carrying my Invention into effect I fix on the end of the back shaft of such
machine a small toothed wheel which is made to gear with another or intermediate
wheel. This intermediate or toothed wheel is provided with a crank pin which takes
one end of the lever used for racking the said cylinder, the opposite end terminating
in a pawl or clawker: the said lever is provided with a guide and a suitable spring to
keep the same down.
Or, instead of employing the aformentioned intermediate wheel I fix on the end of
the back shaft a small disc and at a suitable distance from the centre of the said disc
I secure a pin which takes one end of the lever used for racking the cylinder, a
suitable guide, catch, and check spring also being provided the effect of this latter
arrangement is identical to the first described means.
:
Of course it will be understood that instead of using the disc with the eccentric
pin, a crank arm provided with a pin could be employed to effect the same object,
but I prefer the disc as described.
By the aforedescribed means 1 am enabled to run such machines at a greater speed
and certainty than heretofore whereas, in the old system the pawl or clawker was
caused to rise by means of a weight fixed on the opposite end and operated by a
suitably shaped cam, such motion being uncertain at high speeds.

page_text: Again, in the old system the clawker was connected with the front shaft and
consequently moved with each revolution of the same, whereas by ny improvements
the said clawker is connected with the back shaft or supplementary wheel which only
makes one revolution to two of 'the front shaft thus enabling me to impart a steadier
and more reliable action to the said chawker. Whereas the old systein only clawked
once same as now-but was put through two motions.
And in order that my Invention may be fully understood I will now proceed to
describe the Drawing hereto annexed, which principally illustrate the parts of point-
seaming machines to which my Invention particularly refers.

DESCRIPTION OF THE DRAWINGS.
Fig. 1. is a side view showing the means for racking the cylinder from a supplementary
or intermediate wheel.
Fig. 2. (Sheet 2) is a side view showing the means of racking the cylinder from the
back shaft.
Fig. 3 (Sheet 2) is a section thro' the line a. b. (Fig. 2).
A is toothed wheel on front shaft. B toothed wheel gearing with A on back shaft.
C' disc fixed on back shaft and D the eccentric pin fixed on the disc C.
E is the clawker lever, F the guide and G the check spring. H is a bracket fixed
to stationary ring or cylinder, padded with leather for preventing clawker bouncing
on ratchet, and I a lug cast on clawker for resting in said bracket H.
J is the ratchet wheel for racking the said cylinder, K a small toothed wheel on
the same shaft, and L the cylinder which carries the points.
In Fig. 1 it will be seen that instead of a spring check I employ a drop check M.
N is the intermediate or supplementary wheel driven. in this instance from the
back shaft.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The use of an intermediate or supplementary wheel provided with a crank pin
connecting with one end of the pawl for the purpose of racking the cylinder of a
point seaming machine all substantially as described and illustrated by the
accompanying Drawings.
2nd. The employment of a disc or crank arm fixed to the back shaft of a point-
seaming machine provided with a crank pin connecting with one end of the lever
or pawl for the purpose of racking the cylinder of such machine all substantially as
described and illustrated in the accompanying Drawings.
3rd. The means of imparting one motion only to the clawker of a point-seaming
machine while the front shaft of the same makes two revolutions all substantially as
described.
