Improvements in Wood and like Moulding Machines.
I, JOHANN GEORG SEEBERGER, of Hechtstrasse 23, Dresden, in the Empire
of Germany, Joiner, 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 this invention is to provide a protection device for moulding
machines whereby injury to the hand of the machine attendant through the
rotating knife is entirely obviated.
The invention is illustrated by the accompanying drawings, Figure 1 being
a front view of a moulding machine with the protection device applied,
Figure 2 a plan of same, Figure 3 an end view, and Figure 4 a detail to a larger
scale.
On the bed plate a is secured a spindle 6 whose object is to adjust the height of
the bearing d in which the axle c is journalled. The axle e carries on one end the
driving pulley e and on the other end of the axle, the knife head f is secured..
The knife head flies parallel to dove-tailed grooves in the axle c, in which grooves
the knives g, are fastened by screws to the knife head f. To protect the fingers
of the operator of the machine from injury by the knife g a hood h is provided
which covers the working parts and also the knife towards the attendant is by
this means entirely shut off. This hood is completely closed on one side by a
cover plate so that the knife revolves within a casing, the hood being attached to.
a lever k which turns about a pivot i, so that the hood may be raised at will. The
hood his continually pressed down upon the piece of work, and in order that this.
pressure may be regulated an adjustable sliding weight is secured on the lever k.
A set screw n is provided which enters a nut on the lever k and permits of the
adjustment of the hood as close to the working parts as is practicable, and also of
regulating the pressure of the hood upon the piece of work without changing the
load, the lower end of said set screw bearing on the bed plate a of the machine for
this purpose.
Bearing on the work piece in the machine are rollers n carried by brackets o
from the side of the bed plate a, and the piece of work is thus kept by downward
pressure on the work table. These bed rollers are removable to suit the thickness.
of the work piece.
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 moulding machine the combination of a hood attached to a lever k on
which is an adjustable weight and a set screw m said hood being closed in the
direction of the operator, a knife g adjustable in the relation to the work table
by means of the spindle b and rollers n No carried as to exert a downward
pressure on the work, substantially as described with reference to the drawings
annexed.

to a weighted lever and operating as described with reference to the drawings
