PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Oil Grooves or Key
Grooves in Metal Frames and Wheels.
I JOSEPH BOYLAN of South Holme Liversedge in the County of York
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
For aforesaid purposes I employ at one end of a suitable screw threaded spindle
one or more adjustable cutters projecting beyond the surface of the spindle, also,
a nut the periphery of which is cut so as to form a ratchet wheel. On a portion
of the said wheel I place a bent lever on which I mount a paul which operates
within the teeth of the ratchet wheel and gives motion to the same.
To prevent
the screw spindle from rotating when apparatus is in motion I cut a groove on one
side of the spindle into which I fix a key mounted on a lever. On the cutter end
of the spindle I fix suitable adjustable bosses or runners to suit the various sizes
of holes to be grooved so as to keep the cutter or cutters in contact with the metal
to be cut. Provision is made for making the screw in two parts where the grooves
to be cut are required to be of more than the ordinary length.

Grooves in Metal Frames and Wheels.
JOSEPH BOYLAN, of South Holme Liversedge in the County of York,
Engineer, 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 :-
Apparatus constructed according to my invention is for the purpose of cutting
oil grooves and key grooves in metal frames and wheels.
In order that my invention may be fully understood I have hereunto annexed a
sheet of drawings.
Fig. 1. is a side view of the screw spindle shewing adjustable cutters 2 & 3. also
groove 4. Fig. 2 is the end view of same.
Figs. 3 & 4. are views of the bent lever this having a ratchet motion fixed at the
end. The hole 5 is threaded to suit spindle Fig. 1.
Figs. 5 & 6 are views of the lever which prevents spindle Fig. 1 from rotating,
when nut 5 is in motion by key 7 sliding in groove 4. Space 8 enables the
cutters 2 & 3 to be drawn clear through any hole to be grooved.
Figs. 7 & 8 are suitable adjustable bosses or runners; for the different sizes of
holes, upon which are two nipples which fit freely into holes A & B in Fig. 1; and
can be drawn clear through the hole by passing into space 11.
The Mode of Cutting.-Fix the cutters in the proper position.
screw end first, through the hole to be grooved.
Then put on the lever Figs. 5 & 6, next the lever Figs. 3 & 4.
the latter draws the cutters through the hole.
