COMPLETE SPECIFICATION.
Improved Apparatus for Fluting Picture Frame and other
Mouldings.
I, JULIUS GOLDBERG, of Garden Street, Radford, Nottingham, White prepared
moulding manufacturer, 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side view of the frame I employ for carrying a knife when fluting
the concave members of mouldings.
Figure 2 is a plan of the same showing portions of the fixed bed and mould carrying
bed hereafter referred to.
Figure 3 shows a side view of the frame carrying the knife when fluting
O, G, mouldings.
Figure 4 is a plan of the same.
And Figures 5 and 6 show respectively an end view and a front view of one of the
fluting knives I employ.
To the fixed bed A upon which the mould carrying bed A' slides see Figures 1
and 2 near its front edge I secure a vertically slotted bracket B, in which the front
end of a frame is free to rise and fall, the back end of the frame is hinged to
bearings which are capable of adjustment on each side of a vertically slotted
pillar B secured near the back edge of the fixed bed. When adjusted the bearings are
secured in position by a nut on the screw threaded end of a bolt passed through them
and the vertical slot of the pillar, the frame is provided with two bearings C in which

page_text: a spindle 3 is free to turn, between the sides of the frame the bearings form a
cylinder which lies and slides upon the concave part of the moulding to be fluted, the
spindle near its left end is slotted to receive a fluting knife D which is secured in
position by a set screw passing through the end of the spindle, and shown only at
Figure 2. At Figure 1 the lower end of the outer bearing C2 is broken off to show
the fluting knife in the spindle slot, the right end of the spindle is formed square to
receive a hand lever (4 for the use of the attendant, by which the partial revolution
of the fluting knife is effected, the length of the flutes cut are regulated by two
adjustable stop plates C which are secured to one side of the frame, one at the front
of the hand lever, and the other at the back.
The frame and all it carries is counterbalanced by one end of a cord being attached
to its front end, the other end to a spring conveniently placed above the frame, or
the cord may be passed over a grooved pulley and have its outer end attached to a
weight. The cord pulley and spring or weight being those usually employed are not
shown in the Drawings.
The above described apparatus I employ for fluting the concave members of
mouldings, in the following manner.
The attendant having secured a length of moulding E to the sliding bed A¹ he
lowers the frame Cuntil the bearing cylinder rests upon the concave part of the
moulding with the handle from him, as shown at Figure 1, he then pulls it towards
him into the position shown by the dotted lines and after returning it to its backward
position he allows the spring or weight to lift the frame for the fluting knife to clear
the moulding, and then racks the sliding bed the distance of the width of the fluting
knife, which is of the same length as one tooth of the rack F which is held up to a
stop F which rises and falls in a block secured near the front edge of the fixed bed
in the usual way. The above described movements being repeated after the sliding
bed has been racked one tooth at a time until the whole length of the moulding has
been fluted as shown at E¹.
The fluting knife shown at Figures 5 and 6 will cut ten flutes, each time the bed A¹
is racked one tooth, but I do not confine myself to that number, but when narrower
fluting is required, I employ a knife having more teeth and when wider fluting is
required I employ a knife having fewer teeth.
And for fluting O. G. mouldings I employ a fixed bed A see Figures 3 and 4, on
which a mould carrying bed A' slides as before described together with a spindle and
cylinder B carrying a fluting knife D of the size required which rocks in a bearing
bracket D, from each side of which studs project. these studs slide in semicircular
grooves E¹ on the inside of a fixed frame E. At Figure 3 the left side of this frame
is broken away to show the left side of the bearing bracket D¹ and the semicircular
groove E at its right end. The frame E is capable of adjustment vertically by
means of screws and lock nuts on a pillar 3 secured near the front edge of the fixed
bed A, the upper end of the bearing bracket has a hand lever D² hinged to it, the
lower end of which is connected by a bent link D³ to a stud D₁ which projects from
the spindle or cylinder, the bearing bracket D' and grooved bracket E, are counter-
balanced by a cord and weight or spring as before described, and to the right side of
the frame E, a template block E2 is adjusted, the block is the reverse shape to the
moulding to be fluted, and rests and slides upon it.
The fluting is effected as follows:-The attendant having secured a length
of O, G, moulding F3 in its proper position to the sliding bed A', he lowers the
frame E until the template rests upon the moulding the underside of the template
being the reverse shape to the O G moulding to be fluted lies upon the moulding,
and prevents the knife cutting too deep, the moulding sliding under the template each
time it is traversed for the next set of flutings, then the handle D2 being towards him
he firmly holds the frame towards him to prevent it sliding in the groove E then by
pushing the upper end of the hand lever from him to H see Figure 3 the knife will
Alute the concave part of the OG moulding beyond which the fluting knife cannot
be turned but pressure upon the hand lever being continued the bracket will slide in
the groove E to H' and the fluting knife will be traversed the portion of a circle

page_text: required and flute the convex part of the moulding after each such movement the
attendant allows the spring or weight to lift the frame for the fluting knife to clear
the moulding, and then racks the sliding bed the length of one tooth of the rack F
and holds it up to a stop F1 repeating such movements until the whole length of the
moulding has been fluted as shown at F4.
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 is
1st. The construction and employment of a fluting knife and apparatus for fluting
concave moulding substantially as described and shown by Figures 1. 2. 5 and 6.
2nd. The construction and employment of a fluting knife and apparatus for fluting
O. G mouldings substantially as described and shown by Figures 3. 4. 5 and 6.
