attached, in any position, to tables, trees, vertical or horizontal planks, posts, and
the like, and readily detached again.
The clamping arrangement is shown in the annexed drawing:-
Fig. 1, being a side elevation.
Fig. 2, a back view, and
Fig. 3, a plan.
The mouth intended to receive the wood is formed by the two jaws a and b.
Jaw a can revolve on a pivot d arranged on the frame e, and can be shifted by
means of eccentric leverse (which aro pivoted on the fence-board f) and can be
set by means of the pawl g. Jaw b is arranged on a jack or trestle which slides
along the frame c, being shifted by means of screw i which is adjustable within
the slot c', and the eccentric lever which is pivoted on an eye at the head of the
screw, by which means it can be fixed in position with the aid of the serrations
or notches arranged at the upper edge of frame c. The back part of frame c
is L-shaped, the two sides of the angle 7 and m being made square to the same
width as the front part. Both the outer surfaces of the sides of the angle, and on
of their lateral surfaces, are provided throughout their whole length with serrated
notches .
On these two sides of the angle 2 and m a box or a slide o can be
shifted, and fixed with its upper surface, according to the position, in one or the
other of the four surfaces provided with serrated notches. This slide which may
therefore be brought into four different positions with regard to the "mouth,"
serves for fixing the appliance to any suitable object, whether horizontal or ver-
tical. In either case the position of the mouth of the clamp is independent of
that of the object to which it is fixed, and the piece of wood fixed in it can there-
fore always be brought into the most advantageous position for its being con-
veniently worked. This constitutes the novelty and peculiarity of the whole
arrangement. The slide box o has, at the inside surface of its top-part, a catch t,
by means of which, with the aid of spring p, it can be fixed in any position on
the two sides of the angle. The eccentric lever r, arranged with liberty to oscillate
between the checks and the axles of the slide box o, serves for fixing the whole
appliance to the object to which it is to be fastened, and which should be brought
between the inner surface of the respective leg of the angle and the serrated
eccentric surface. In order to have a support in the event of the upper side of
.

angle (that is to say, particularly if the apparatus is fastened to vertical objects,
such as trees, posts, and the like) an L piece u is arranged on the frame s.
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;-
-
An improved clamp for wood workers consisting of a frame the back part of
which is angular in shape and with the slides and m thereof provided both on their
outer and upon one of their lateral surfaces with serrations or notches and capable
of being fixed in position upon a bench or other object by means of an eccentric
lever r, carried by a slide box o capable of adjustment on the members of the
aforesaid angle in such a manner as to bring the object to be operated upon in a
convenient position for the operator.
