PROVISIONAL SPECIFICATION.
An Improved Holder or Tool for use in Making Screwed Nipples.
I, DANIEL ALOYSIUS HOLLAND, of 47 Paul Street, Boston, in the County
of Suffolk and State of Massachusetts, United States of America, Brass Moulder,
do hereby declare the nature of this invention to be as follows:
My invention relates to an improvement in nipple holders, and has for its object
to provide a means whereby the length of pipe from which the nipple is to be cut
may be firmly held while the completion of the nipple is being effected.
A further
object of the invention is to so construct the device that the nipple, when finished,
may be conveniently removed in perfect shape.
The nipple holder comprises a tubular body screwed upon a mandrel and
adjustable thereon to receive a nipple having long or short threaded extremities.
Within the body are two loosely fitting discs connected by bolts and separated by
a wedge or key passing through slots in the head and through a bevelled key-way
in one of the discs, these discs and key acting in conjunction to wedge against the
end of the nipple, as hereafter described. Within the outer end of the body of
the head a chuck plate is fitted provided with a central threaded opening adapted
to receive one threaded end of the nipple and with lugs which when the plate is
secured in position by set screws fit into corresponding recesses in the body whereby
the plate is prevented from turning. A number of chuck plates are used in con-
nection with the head, each provided with a threaded opening of different diameter,
to accommodate pipe of different sizes.
In using the tool, a proper chuck plate having been inserted in the body and the
body having been adjusted upon the mandrel to take the proposed length of the
nipple thread, the threaded end of the pipe from which the nipple is to be made is
screwed into the chuck plate until it bears against the outer disc, the key is then
driven in, and the said disc is forced tightly against the pipe end so that the latter
is effectually prevented from turning while the length of the nipple is being cut
off and the other end threaded. When the nipple is completed, the key is driven
out and the nipple thereby released from the pressure of the disc which enables the
nipple to be readily removed in perfect shape.

COMPLETE SPECIFICATION.
An Improved Holder or Tool for use in Making Screwed Nipples.
I, DANIEL ALOYSIUS HOLLAND of 47, Paul Street, Boston, in the County
of Suffolk, and State of Massachusetts, United States of America, Brass Moulder,
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 relates to an improvement in nipple holders and has for its object to
provide a means whereby the length of pipe from which the nipple is to be cut may
be firmly held while the completion of the nipple is being effected. A further object
of the invention is to so construct the device that the nipple when finished may be
conveniently removed in perfect shape.

page_text: The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which Figure 1 is a central longitudinal section through the
device; Figure 2 is a plan view of the same; and Figure 3 is a front elevation.
Similar figures and letters of reference indicate corresponding parts in all the
views.
In carrying out the invention, the head A consists of a tubular body 10 interiorly
threaded on its inner end to screw upon the exteriorly threaded end of a supporting
stem 11 which may be solid or tubular and when tubular the end extending into
the head is closed by an attached or integral cap 12. The head is provided with
'à lock nut 13 also screwed upon the stem and the threaded surface of the stem is
of such length that the head may be manipulated thereon to receive a nipple
having long or short threaded extremities. The body is provided with a slot 14
in its upper face a comparatively short distance from its forward end extending
through to the interior and a diametrically-aligning similar, but preferably shorter,
slot 15 in its under face and in opposite sides of its forward or outer end aligning
recesses 16 are produced. Within the body, in front of the cap 12 of the stem, two
loosely fitting discs 17 and 18 are introduced, which discs are preferably connected
by bolts 19 located at opposite sides of the centre and provided with nuts 20
outside of the outer disc, as shewn in Figures 1 and 3, the heads of the bolts being
countersunk in the inner face of the inner disc. The apertures through which the
bolts pass are of sufficient size to permit of the free movement of the discs on both
sides. In the forward or outer face of the inner disc, a central vertical channel 21
is cut, the base wall of which is bevelled or inclined from the top outwardly to the
bottom, as illustrated in Figure 1. A wedge-shaped key 22 is employed in con-
nection with the head, which key is passed through the upper head slot, the channel
in the inner disc, and likewise the lower head slot, and the key is of sufficient
length to project beyond the top and bottom of the head, being provided near its
lower end with a transverse pin 23 to prevent it being drawn entirely from its seat.
Within the forward or outer end of the body of the head a chuck plate 24 is fitted
provided with a central threaded opening 25 adapted to receive one threaded end
of the nipple and with opposed peripheral lugs 26 which, when the plate is placed
in position, fit neatly into the side recesses 16 of the body, as shewn in Figure 3,
whereby the plate is prevented from turning and the danger of the plate falling
from the head is avoided by passing through the head into the plate preferably two
screws or pins 27 likewise illustrated in Figure 3. A. number of chuck plates are
used in connection with the head, each provided with a central threaded opening
of different diameter, to accommodate pipe of different sizes.
In operation, a proper chuck plate having been inserted in the head and the head
having been adjusted upon the stem to take the proposed length of the nipple
thread the threaded end of the pipe from which the nipple is to be made is screwed
into the chuck plate until the inner end contacts with the outer face of the outer
disc 18 and when this occurs the key is driven down and the said disc 18 is forced
to such a firm and positive contact with the pipe that the latter is effectually pre-
vented from turning while the length of the nipple is being cut off and the outer
end threaded. When the nipple is completed, the key is driven up and the nipple
thereby released from the pressure of the disc 18 which enables the nipple to be
readily removed from the head in perfect shape.
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:
1. In a nipple holder, the combination, with a stem, of a head screwed upon the
stem, consisting of a tubular body provided with an upper and a lower slot, discs
Inaal- ftted in the hady a wodna kov edanted to pass through the body openings

page_text: between and in contact with the discs and a chuck plate attached to said head,
substantially as specified.
2. In a nipple holder, the combination, with a stem, of a head screwed upon the
stem, consisting of a tubular body provided with an upper and a lower opening and
two adjustably-connected discs loosely fitted in the body, the face of one disc being
provided with an inclined channel a wedge shaped key adapted to pass through
the body openings between the discs and through the channel thereof and a.
detachable chuck plate fitted in the outer end of the body, substantially as
specified.
3. In a nipple holder, the combination, with a stem provided with a closed end
and a head screwed upon the stem consisting of a tubular body provided with au
upper and a lower opening and side recesses and adjustably connected discs loosely
fitted in the body, one of which is provided with an inclined channelled face, of a
wedge key adapted to pass through the head openings and between the discs, and
a chuck plate having peripheral lugs capable of fitting in the head recesses,
substantially as specified.
