Improvements in the Feed Mechanism for Logs or Deals in Vertical
Saw Frames.
I, WILLIAM GRAHAM BUCHANAN of 11 Dempster Street, Greenock, in the County
of Renfrew, Manager of Saw Mills do hereby declare the nature of this invention to
be as follows:-
:-
The object of my invention is to provide a continuous or nearly continuous automatic
feed for logs or deals in vertical saw frames in place of the reciprocating motion now
in common use therefor. For this purpose I provide an extra bar or rod fixed to the
feed regulator of an ordinary vertical saw frame, and attached also at a suitable position
on the feed wheel of the frame. This arm is extended, bent, and clamped in a suitable
position on the feed wheel, so as to clear the rod for reciprocating feed. An attachment
is made by the ordinary method of clamps governed by screw adjustments of the rods
to the feed wheel. The rocking lever for the reciprocating movement is made with
two adjustable attachments for carrying the ends of the levers or rods. These can be
moved nearer or farther from the centre as may be required, by screws affixed at the
end of the rocking gear. At every movement of the eccentric fixed on the crank
shaft, the rods are actuated and a continuous motion is thus automatically produced,
and the logs or deals are fed regularly and continuously on to the saws in the vertical
saw frames.

I WILLIAM GRAHAM BUCHANAN 11 Dempster Street Greenock in the County of
Renfrew Manager of saw-mills, 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 my invention is to provide a continuous or nearly continuous automatic

understood I append drawings in which A is the extra rod or lever attached at one
end to the rocking motion B by adjustable screws and to the wheel at C by clamps
and screws. Similar letters refer to similar parts in figures 1 and 2 which represent
side and end elevation respectively.
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 I am aware of Law's
patent No. 891086 and I wish it to be understood that I do not claim anything covered
thereby and that what I claim is :—
I. An attachment of extra rod or lover fitted by adjustable screws to the rocking
lever of a vertical saw-frame and attached also to the wheel of the feed mechanism of
ordinary vertical saw-frames as described and illustrated.
