page_text: We JAMES CONNOLLY and THOMAS CONNOLLY both of 65 Wharfdale Road, Kings
Cross, London N. Tyresmiths 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 :-
Our Invention has reference to the type of moulding machines usually employed for
cutting or shaping mouldings for picture frames and the like, and has for its object to
provide means for overcoming the disadvantages caused by the uneven wear of the
vertical spindle or shaft-to which would be attached the cutter-due to the raising
and lowering of said spindle, so as to bring the cutter to the height required by the
special work in hand.
In order that our invention may be the better understood, we have appended the
accompanying sheet of drawings, in which Figure 1 is a sectional elevational view of
the improved moulding machine according to our invention, and Figure 2 is a plan of
same.
In accordance with our invention we employ an enclosing case A, flanged at its
upper end A' to allow of the attachment of same to a corresponding flange on the
under surface of the moulding table C, said enclosing case being secured to the base c
of the frame of the table by suitable legs or supports b. Within the enclosing
case A above mentioned, moves vertically a second inner case D, the lower part d'
of which is bored or otherwise recessed to serve as a socket for the reception of a
cutter shaft or spindle d". Upon the upper part of the inner case D, is cast, or
otherwise formed a bearing d for the support of the shaft or spindle d" aforesaid. In
the lower part of the enclosing case A are formed two tapped holes in which takes a
vertical screw e provided with a hand wheel e', by means of which the inner case D
may be raised and lowered as may be desired.
Upon the frame C of the moulding table are bolted or otherwise secured thereto
two standards or brackets G, upon which is mounted, in suitable bearings, a horizontal
driving shaft E (Figure 2), carrying the central pulley f, and outer pulleys and f",
the latter being preferably a loose pulley to allow of the stoppage of the cutter by the
shifting of the driving belt from the fixed to the loose pulley. A belt B, riding upon

page_text: the pulley, and passing through vertical openings in the frame of the table and
corresponding openings a in the enclosing case A and inner case D, actuates a vertical
pulley e secured upon the spindle or shaft d".
In operation, motion is imparted to the driving shaft E from any convenient source
of power, whence it is transmitted by means of the pulley and belt B to the vertical
pulley e, whereby the cutter is rotated at the desired speed; and, in order to vary
the height of the cutter to suit any special work, the inner case D, and with it the
shaft and vertical pulley ell are raised or lowered (as the case may be) by means
of the screw e actuated by the hand wheel e'.
By the arrangement above described, it will be observed that instead of varying
the height of the cutter by raising the "cutter shaft" in its bearings,-under which
circumstances it would be impossible to maintain even wear of the bearing surfaces-
we are enabled to raise or lower the inner case D, and in conjunction therewith the
bearings and shaft or spindle d"; the latter, by this means always retaining its initial
position in the bearings, and thus ensure to the bearings and also to the bearing
surfaces of the shaft or spindle du even and regular wear.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
1°. In the improved moulding machine herein described, the adaptation thereto of a
cutter shaft or spindle revolving in bearings capable of vertical motion within an
enclosing case, substantially as herein set forth and shown in the accompanying
drawings.
20. In the improved moulding machine referred to in the preceding claim, the
employment of an inner case D, to which vertical motion is imparted by means of a
screw e and wheel handle e', substantially as and for the purpose herein set forth.
30. The improved moulding machine substantially as herein described and illustrated
in the accompanying drawings.
