Fig. 4. Plan.
In carrying out the invention I construct the block or base A. with a groove or
slot B one face b of the slot being vertical and the face b' opposite thereto inclined.
In the slot B is fitted a wedge shaped strip or piece C of corresponding shape
and size.
The hackle pins D are placed in the groove B between the vertical face b of
the block A and the face c of the wedge C which form a clamp to hold the lower
ends of the steel pins D. The faces and care preferably both lined or coated
with a sheet of lead or other soft metal or material into which under pressure the
pins D will embed themselves.
The wedge or clamping piece C is drawn down by screws E preferably passing
through the bottom of the block or otherwise arranged such as by passing down
from the top or through lugs or plates. And in addition to or instead of the
inclined side to the slot B screws may be employed horizontally or otherwise to
give the desired pressure to the clamping block. Further the inclined side of
the slot may be made if desired with a loose adjusting plate held in position by
screws.
At one or both ends of the block A 1 place an auxiliary clamp G with a
thin blade H attached by screws or bolts by which the pins D are pressed
together before they are finally clamped in position. When one end clamp only is
used a shoulder pin or the like is employed at the other end against which the
pins D can be pressed. The end clamp may if desired be removed when the main
clamp B is fastened.
The pins can be arranged in rows to be placed in the base by inserting their
sharp ends into holes in a block of wood or other material at the desired distances
apart. While thus held by their sharp ends the base ends may be placed in a

page_text: mould or bath and coated with an electro deposit of copper or other metal which
will hold them in sets of say 6 to 12 or thereabouts and render them capable of
being handled in this form instead of singly as heretofore. This method may also
be applied where it is desired to solder pins to the face of a block or holder
where no clamping device could be applied and even to the old plan of inserting
them in a slot and affixing by soldering, and is applicable also to gill stocks for
preparing machinery.
To remove and replace one or more pins when damaged the screws which hold
the clamping piece are loosened when such of the pins as are desired can be
withdrawn and others substituted and the whole reclamped again.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
11
1. A holder for hackle or gill pins comprising a base A provided with a slot
or groove a clamping piece of corresponding shape fitting therein and held in
position by screws or bolts substantially as described.
2. The method of securing hackle or gill pins for insertion in stocks which
consists in attaching the base ends of the pins together by an electric deposit of
copper or other metal coated upon them substantially as described.
3. A holder or stock for hackle or gill pins constructed substantially as described
and shown.
