PROVISIONAL SPECIFICATION.
Improvements in Cramps Applicable for Holding Metal Pipes or
like Articles.
I, BARNARD AKROYD of Crag Lane Top. Wilsden near Bingley in the County
of York, Plumber, do hereby declare the nature of this invention to be as follows,
that is to say :—
It relates to improvements in cramps applicable for holding metal pipes in position
while same are being joined properly together, and consists of forming said cramps
in such a manner that they may bo readily applied for such purposes and as readily
detached when said object of jointing has been finally performed.
This I attain by forming a screw crainp to have two, three or more arms, each of
which is to lay hold of one or other part of the pipe or pipes that are to be joined
together.
These several arms of the cramp are arranged in suitable relative positions and the
screw cramping parts in each arm are so formed that by turning thumb-and-finger
pieces they are released so as to be detachable from said arms, in this manner
liberating the whole cramp when the object of jointing the pipes has been
accomplished.
Dated this 2nd day of February 1889.

COMPLETE SPECIFICATION.
Improvements in Cramps Applicable for Holding Metal Pipes or
like Articles.
I, BARNARD AKROYD of Crag Lane Top, Wilslen near Bingley in the County of
York, Plumber, 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, that is to say :-
It relates to improvements in cramps applicable for holding metal pipes in position
while same are being joined together as by soldering etc., and consists of forming
said cramps in such a manner that they may be readily applied for such purposes and
as readily detached when said object of jointing has been finally performed.
In order that my said invention may be more readily understood I have hereunto
appended sheets of drawings illustrative thereof to which by figures and letters
reference is made in the following description.
Figs. 1 and 2 are front and end elevations respectively of a cramp made in
accordance with this invention.
Fig. 3 is a view of said cramp as seen from above.
The object of this invention is attained by making use of a suitable base plate a
having projections & through or in each of which a slot is made for the reception of
a bolt.
b
To each of the projections 6 are attached projecting jaws c or c'. The jaws c* are
made to open so that any article they have to grip (as the pipe d) may be readily
placed between and held by said hinged jaws being moved or operated by the winged
nut e so as to grip the article between it and its fixed jaw c.
The jaws c' are formed by having a sliding jaw c operated by the screw mounted
to move through the detachable piece g. This piece is made detachable by the
thumb-screws overlapping same in one position while when turned in the opposite

may
direction they fall within the slots gland so the piece together with its jaw may
be removed from the jaw by which means any article to be held by said jaw
be readily placed therein, same as is the tapk, and held thereby in suitable relative
position with the article to which it has to be attached, as with the pipe d. until the
proper attachment has been made, when the whole pipe and its tap or whatever else
may have been so joined together may be removed us will be seen.
"
The jaws and are made to suit the slotted projections so that same may be
moved or adjusted to meet the several requirements of bent pieces of pipes, curved
articles or the like, that may be required to be held in proximity with each other as is
from time to time found necessary.
The base plate is formed as shewn so that it affords room for weighting pieces to
hold the whole cramp in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is
1. The base plate a formed as shown, the jaws e and having moveable jaws e
and respectively, and means for operating said jaws in combination the same being
arranged to operate substantially as specified.
Duted this 2nd day of November 1889.
