An Improved Machine for Stabbing Holes in Pattern Sets, or

Papers.
We ALFRED BLADES SMITH of 8 Hague Street, Whitfeld, Glossop, in the
County of Derbyshire, Accountant, and EDWIN BLAKE SMITH, of Barcicroft,
Burnage, Withington, near Manchester, in the County of Lancaster, Mechanical
Draughtsman, do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of an improved machine for stabbing
holes in pattern sets viz. a number of sample pieces of cotton, silk worsted mixed
goods or papers placed on top. of each other & hereafter called the pattern set
or set.
This invention consists principally of a frame with a base which is secured to a
suitable support. Part of this frame consists of a long boss in which, at the
lower end, a sleeve will slide. A spindle, the top end of which is fastened by
means of links to the lever, & the bottom of which is prepared to receive the
stabbing needle, will slide inside the sleeve when the spring, holding apart the
collar on the spindle & the sleeve, is compressed by the lever being pulled down &
the bottom of the sleeve touching the pattern set. By pulling down the lever the
spindle & sleeve slide down the boss until the sleeve touches the pattern set, then
the pattern set offering a resistance to the motion of the sleeve, the spring is
compressed by the collar on the spindle travelling down; & so a pressure is put
on the set before the needle reaches it.
The pattern set is also held in position by the sleeve.
When the spring has been compressed through a certain space, the needle enters
the pattern set, & stabs a hole in it; & at the same time a constantly increasing
pressure is being put on the pattern set by the compressing of the spring.
On releasing the lever handle the needle quickly retreats into the sleeve, which
therefore, also serves the purpose of preventing the needle from raising the set
from the table. We also use a combined set-screw & guide.
As a set-screw we use it to secure the needle in position ; & as a guide we use
it to slide up & down in slots in the boss of the aforesaid frame & in the sleeve.
We also cut a small piece out of the sleeve at the bottom so as to miss the gauge,
by which we regulate the distance from the edge of the set at which the hole will
be stabbed.
We prefer to make the gauge-movable by means of a slide & thumb screw.
We also adopt an indiarubber stop into which the needle plunges. A counter-
balance is also placed on the lever.
We prefer also to put a small piece of leather over the hole at the bottom of the
sleeve, to carry grease, so that the needle may be greased automatically.

We ALFRED BLADES SMITH of 8 Hague Street Whitfield Glossop in the
County of Derbyshire, Accountant, and EDWIN BLAKE SMITH of Barcicroft
Burnage Withington Manchester in the County of Lancaster, Mechanical
Draughtsman 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 construction of an improved machine for stabbing
holes in pattern sets, namely small pieces of the following placed on top of each
other, of cotton, silk worsted mixed goods or papers.
The nature of our invention & the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the sheet
of drawings annexed & the following explanation thereof.
Fig. 1 is a sectional elevation & Fig. 2 a plan of our improved machine.
This invention consists principally of a frame A part of which frame is composed
of a long boss B having a slot V cut in the front of it. The spindle D & the
sleeve C, which are held apart by a spring H, slide inside the aforesaid boss. B.
The sleeve C has a hole S in the bottom to allow the needle G to pass through
& has also a slot T cut in the front to allow it to move a certain distance up &
down the set-screw M. The lever F, connected to the spindle D by the links E,
is pulled in the direction of the boss B by hand or other mechanical means.
weight R is a counterbalance. Attached to the aforesaid spindle D, by means of a
set screw M, is a stabbing needle G which can be readily taken out to be sharpened
by releasing the set-screw M.
The
The stabbing of the hole in the pattern set K denoted on the annexed drawing
can be readily effected by the following means.
When the spindle D is caused to slide inside the boss B the distance between
the sleeve C & the spindle D remains constant due to the force exerted by the
spring H until the sleeve C comes in contact with the pattern set K; as soon as
this contact takes place the motion of the sleeve C is arrested but the motion of
the spindle D being continued, the stabbing needle G, connected to the spindle D
as before mentioned, slides down the sleeve C & through the pattern set K, the
pressure of the sleeve C on the pattern set K meanwhile being continually increased
due to the compression of the spring H. When the spindle D is raised the stabbing
needle G is withdrawn from the pattern set K & retreats inside the sleeve C. The
compressed spring H keeps the sleeve C on the pattern set K until the needle G
has retreated inside the sleeve C which retreat goes on until the top of the slot T
in the sleeve C comes in contact with the set-screw M, then all three, namely
spindle D, sleeve C & stabbing needle G are drawn up clear of the pattern set K
at the same rate.
We adopt an india rubber plug P in the base of the frame A for the needle G to
plunge into after passing through the pattern set K.
We also employ a gauge N adjusted by means of a thumb screw O to regulate
the distance of the hole from the edge of the pattern set.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is :-
:-
First. The combination of a spindle with a needle attached, & a sliding sleeve
held apart from the spindle by a spring in such a manuer as to enable a pressure

page_text: to be put on the pattern set before & whilst a hole is being stabbed in the pattern
set, & also to enable such pressure to remain on until the needle is withdrawn.
Second. The combination of a spindle & a sliding sleeve, having a slot, & a set
screw working in the slots in the sleeve & in the boss of the frame holding the
needle in a fixed position in the spindle & yet allowing the sleeve & spindle to
have different rates of motion in the same plane substantially as hereinbefore
described & illustrated by the drawings annexed.
