COMPLETE SPECIFICATION
Improvements in Clamps Employed in the Manufacture of Frames
I, JOHN BRIERLEY HOWARD, of the Firm of Brierley & Howard, Penny Bank
Chambers, Halifax, in the County of York, Patent Agents, do hereby declare the
nature of this invention, which has been communicated to me by Johann Schuler,
of Schwabach, Bavaria, in the Empire of Germany, Glazier, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement
This invention relates to an improved tool for pressing and holding together
portions of frames such as are used for pictures, windows, and the like, in the
process of joining them in the construction of a complete fiame By means of this
tool, frames bent at right or other angles may be finished
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig 118 a plan view of the improved tool designed for producing a simple
bend
Fig 2 is a plan view of the improved tool when used for a more complicated
bend or corner
Fig 3 illustrate elevations and plans of the presser plates detached
Fig 4 is a sectional end view of Fig 2
Fig 1 is a detail of Fig 1
According to this invention, the tool consists of a bed-plate a with two serrated
holding bars 6 and 62 placed at an angle of 90° to each other, and a slide h free
to move in the bed-plate a, and carrying a presser screw c, and a piesser plate
such as el or e (see Fig 3) Owing to the arrangement of the slide h, the screw c
may be so adjusted as to rest upon the angular point of both the bars 61, 62, or be
directed upon the face of either one of the two
The action is as follows -First apply the chamfered portion of the frame
border g' to the toothed on serrated bar of the bed plate a, and place the first
piece g at right angles upon the glued chamfered end of the portion gl The
presser plate e is then pressed to by means of the screw c, the point of which rests
in the hole f(see Fig 1^) Nails can now be driven in through the holes in the
presser plate e (see Fig 3) for the purpose of fixing the piece g² to the piece g¹
Having loosened the screw c, cover the free face of piece o2 with glue, and then
attach the next piece g³ to the piece 92 in the manner herein described, except that
the piesser plate e¹ is turned 45°, so that the point of screw c will now rest in
the hole (see Fig 1) The combination of two different angles is effected by
using a double presser plate e² consisting of two portions joined at right angles
The parts g2 g³ may be fixed by clinchers which are adjustable in the slits in the
plate h

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim 18
The bed plate a carrying two toothed or serrated bars 61 and 62 at right angles
and

portions of the frame, and the clinchers, all in combination as and for the purpose
herein described and substantially as illustrated by the annexed drawings
