PROVISIONAL SPECIFICATION.
An Improved Mitre Block and Joint Oramp.
I, HENRY SMOLINSKI, of 21 Trumpet Road, Cleator, in the County of
Cumberland, Painter, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved mitre block and joint cramp which consists
of a metallic frame with mitre blocks enclosing two loose pieces of hard wood with
a saw cut in the centre for cutting a mitre in mouldings of various sizes. Adjoining
the mitre blocks at right angles I provide face plates working in grooves or between
guide bars attached to square cut screws with knurled heads operating to or fro in
blocks situated in any suitable position on the frame.
When it is desired to use the apparatus as a joint cramp the mitre blocks and
loose pieces of hard wood are removed for the purpose of placing the angle of the
joint in between the face plates of the cramp, the said cramp being fixed by means
of the screws hereinbefore mentioned.

COMPLETE SPECIFICATION.
An Improved Mitre Block and Joint Cramp.
I, HENRY SMOLINSKI, of 21 Trumpet Road, Cleator, in the County of
Cumberland, Painter, 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 improved mitre block and joint cramp which consists
of a metallic frame with mitre blocks enclosing one or two loose pieces of hard
wood with a saw cut in the centre for cutting a mitre in mouldings of various
sizes.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a plan of the top of the apparatus.
Fig. 2, is a side elevation.
This invention is constructed with an open metallic frame a with mitre blocks b
enclosing one or two loose pieces of hard wood c with a saw cut d in the centre for
cutting a mitre in mouldings of various sizes. Adjoining the mitre blocks b at
right angles I provide face plates e working in grooves or between guide bars f
attached to square cut screws 9 with knurled heads or wheels operating to or fro
in blocks situated in any suitable position on the frame.
Soft metal if preferable may be inserted in the hard wood c.
To use the apparatus as a joint cramp 1 place the angle of the joint in between
the face plates of the cramp and the loose pieces of hard wood as indicated by
dotted lines in Fig. 1, the said cramp being fixed by means of the screws g herein-
before mentioned.
When cutting or joining the mitres of mouldings, the said mouldings are placed
on the top of the machine with the inside edge of moulding or mouldings resting
on the top of the mitre blocks so as to save the inner edge, by this means the
[Price Rd 1

screwing up.
It will be understood that the shapes, materials and proportions of the parts, with
such modifications as found necessary, may be varied in many ways within the
scope of my invention.
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. In a mitre block and joint cramp, the combination of the open frame a, initre
blocks b hard wood c and saw cut d, with the face plates e, screw g and wheel h, for
cutting mitres to mouldings by means of a saw, substantially as herein described
and according to the accompanying drawing.
2. In a mitre block and joint cramp, the combination of the frame a, mitre
blocks b, loose pieces of wood i, with the face plates e, guide bars f, square cut
screwe g and wheels h, for cramping together mouldings where a mitre is formed,
substantially as herein described and according to the accompanying drawing.
3. In a mitre block and joint cramp, the combination of the soft metal j in one
or more pieces and the loose piece or pieces of hard wood c with the saw cut d,
substantially as herein described and according to the accompanying drawing.
