SPECIFICATION.
Improved Tool or Apparatus for Holding or Clamping Objects while.
being Operated Upon.
I, FREDERICK LINDLEY, of Royston, near Barnsley, in the County of York,
Plumber, Electrician, Gas Fitter, and Sanitary Engineer, 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 :-
The object of my invention is to provide simple and efficient apparatus for holding
articles while being worked at by the operative, such as the joining of an union
and pipe together by a plumber, and the like operations, the said apparatus being
so arranged that it and its clamps or jaws can be readily placed at any angle
required by the situation of the work.
Fig. 1, is a view showing clamps or jaws in side elevation.
Fig. 2, is a viow showing clamps or jaws in front elevation.
Fig. 3, is a side elevation of modification.
Fig. 4, is a plan of Fig. 3.
Fig. 3, is a side elevation of modification of jaws or clamps.
In carrying out my invention 1 employ a spindle A, the lower end of which
can be loosely slid into a footstep or bearing B (and held therein by a thumb
Screw B) upon a wood block C when it is desired to give a support to the
apparatus or tool when the nature of the work will not admit of the tool being
clamped thereon independent of any other support.
The said step or bearing B has boles through it at right angles to each other by
which the position of the spindle A can be changed therein according to the
angle or position it is required to place the tool at through the position of the
work. Carried upon the said spindle A, are bosses D, carrying arms, fingers, or
studs E upon which are secured the clamps or jaws F, by means of bosses G
engaging on the arms, fingers, or studs and set screws I screwing through
the said bosses and against the arms, fingers or studs E.
The jaws or clamps F are strengthened by webs F¹.
The said bosses D have holes at right angles to each other by which the clamps
or jaws F may be altered upon the arms, fingers or studs E and secured thereon as
before set forth. The said clamps or jaws Fare opened or closed to the size of the
object to be gripped or heid, by the screws J pivotted to the top jaw, and passing
through a slot in the lower jaw and having wing-nuts K upon them, by which the
jaws may be regulated as required.
On the top of the spindle A is a screw A¹ with wing nut A' and a cup A'.
By screwing up the said cup A' so that it acts against the top boss, the top jaw
or clamp can be adjusted to a nicety relatively to the lower one, for this purpose
the thumb screw of the top boss is left slack until the adjustment has been effected.
In Figs. 3 and 4, the clamps or jaws are carried by compound arms composed
of arms E and G', and may be changed to any angle required.
The action of this construction is the same as that previously described.
In Fig. 5. The jaws or clamps F are provided with quadrant pieces F* which
are pivotted on the jaws or clamps F, and can be adjusted by means of set screw F³,
and screw F¹

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A tool or apparatus of the kind referred to having a spindle A, carrying arms
provided with jaws or clamps, which said arms can be adjusted or altered relatively
to the spindle A, whereby the position of the jaws or clamps can be altered at
will, substantially as shown and described.
2. The construction and arrangement of parts forming my invention for clamping
objects substantially as shown and described.
