IRUVIDIUNAL DE UIFICATION.
An Attachment or Addition to the Feed of Nail or Tack
Machines.
We, HERBERT STANLEY HARRIS and ARTHUR EDMUND GORSE both of the
Tower Manufacturing Co. Ltd. Nail Makers, Bromsgrove, Worcestershire do
hereby declare the nature of this invention to be as follows:-
The attachment consists of two pieces of steel or other metal so made and
arranged that they slide one within the other up to a certain point in each. A hole
is drilled or made through the whole length of these two pieces of metal. The use
of our invention is to keep enclosed, in the space between the feed and the machine
itself, the material that is being fed into the machine. One part of the said
attachment is fixed to the feed of the machine and moves with it and the other part
is fixed to the machine.

An Attachment or Addition to the Feed of Nail or Tack
Machines.
We, HERBERT STANLEY HARRIS and ARTHUR EDMUND GORSE both of the
Tower Manufacturing Company Limited, Nail Makers, Bromsgrove, in the County
of Worcestershire, do hereby declare the nature of our said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
Our invention has for its object an attachment or addition to the feed of nail or
tack machines which constitutes a guide which is equally effective at all portions,
of the stroke of the feed portion of the machine by which the material from which
the articles are made is kept true and accurately in its course from the feed to that
portion of the machine where it is operated upon to produce the nails, tacks or
other articles of a like nature.
The attachment consists of two pieces of steel or other metal so made and
arranged that they slide one within the other the other up to a certain point in each.
A hole is drilled or made through the whole length of these two pieces of metal.
The use of our invention is to keep enclosed in the space between the feed and the
machine itself, the material that is being fed into the machine. One part of the
said attachment is fixed to the feed of the machine and moves with it, and the other
part is fixed to the machine.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a double sized sheet of drawings
showing one form of our attachment and its connection to a machine which will
suffice to enable others not only to make the attachment as shown in this particular
connection but also modifications of the same to suit the varying conditions met
with in practice.

page_text: Figure 1. is a general perspective view of the attachment which is formed in two
distinct portions A and A'.
Figure 2 is a side elevation of the portion A.
Figure 3. is a side elevation of the portion A¹.
Figure 4 is an end elevation of A when drawn assunder from the portion A¹.
Figure 5. is a cross section of Figure 1.

Figure 6 is a part sectional elevation of a portion of a machine B showing
mode of connecting our attachment A, A' to the machine with the feeder F at the
outer end of its stroke.
Figure 7. shows the same machine and parts as Figure 6. but with the feeder F
at the inner portion of its stroke.
. Our attachment is composed of the two portions A and A¹ forged and shaped or
cast with three guide sliding pieces to each vis. :-to the left portion A of the guide
sliding pieces a², a3 and a* and to the right hand portion A' of a, a and a. It will
be clearly understood that the sliding pieces of A exactly fit between the sliding
pieces of A as clearly shown upon the drawings but more particularly by the cross
section Figure 5. A sufficient amount of the centre portions of each sliding piece
is cut away by boring a hole from end to end when both A and A' are together as
seen at Figures 6 and 7 or this portion may be shaped away so that the wire or
other material W being fed in lengths may be always accurately guided as fed by
the feeder F from left to right as shown by the arrows K. The left portion of the
attachment A is fastened to the feeder F by the set pins and reciprocates with
the feeder F which is operated in any convenient and well known manner in
machines, while the right hand portion A' remains stationary with the machine B.
By this means there is never any gap in the attachment guides, the wire W being
always secured in the desired line of travel while it can be seen inore or less as it is
brought along by the feeder F.
It will be obvious that a greater or less number of sliding pieces a¹ or a³ may
be used as two would do or four or more but I have shown three as meeting the
greatest number or widest range of cases with a minimum amount of fitting and
expense in production. And it will be seen and understood that the wire is
perfectly guided irrespective of gaps between the several lengths. In operating
the machine with our invention attached it is necessary to mount a gripper M which
is shown in action at Figure 7. at the left hand or feed end to hold the short piece
from travelling back with the feeder F. The front end is held in the usual
manner.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The attachment or guide consisting of such like pieces as A and A¹ sliding the
one into the other so as to leave a space at the centre for the wire W substantially
as and for the purpose herein set forth and as shown upon the drawings annexed
hereto.
