PROVISIONAL SPECIFICATION left by William Stettinius. Clark and
Benjamin Moore at the Office of the Commissioners of Patents, with
their Petition, on the 22nd September 1857.-A communication.
We, WILLIAM STETTINIUS CLARK and .BENJAMIN MOORE, of No. 133, High
Holborn, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINES FOR CUTTING SPLINTS FOR
FRICTION MATCHES," (a communication) to be as follows:-
The nature of the Invention will fully appear by reference to the accompany-
ing Drawings, of which Fig. 1 is a front elevation; Fig. 2, plan view; Fig. 3.
section through A, B, exhibiting the position of the bolt; Fig. 4, arrangement
of the cutters; Fig. 5, view of plate, shewing the position of cutters and
plane; Figs. 6, 7, 8, section of the cutters enlarged; Fig. 9, an enlarged view
of the lever P.
A, A, A, in the various Figures represent the framework upon which other
portions of the machine rests; B, the main shaft carrying the fly wheel and
pulley; D, a plate secured to the main shaft B, to which one end of the con-
necting rod E is attached, and the other end to the sliding table F, which
receives its to-and-fro motion by a crank attached to the main shaft B, said
table sliding upon a fixed plate G; H, a box, in which the block of wood is
placed preparatory to cutting into the desired splints; I is a screw, the object
of which is to feed the block towards the cutters; J, the follower for carrying

page_text: the block of wood forward to the cutters by its connection with the screw and
ratchet wheel R and finger L; K is a ratchet wheel secured to the end of the
screw; L is a finger attached to the side of the table G by a stud, the object
of which is to give motion to the ratchet wheel R as the plate F slides to and
fro, and thereby giving motion to the screw, and with it advancing the block
of wood to the outters; M, a pawl for arresting the forward motion of the
ratchet wheel, and with it the screw and block of wood during the operation of
the cutters upon the block; N is a spring having one end secured to the slide
Fand carrying upon the other end a block O; this bolt working through a
slot in the upper end of the lever P, the end of which is raised by the bolt O
passing through; this bolt receives its motion by the advance of the block of
wood depressing the bolt in a recess; a further advance of the screw and block
beyond this bolt the action of the spring N returns it to its position, as seen in
dotted line in Fig. ; the object of this bolt is through its action upon the lever
P, intended to disengage the finger L from the ratchet wheel R,' thereby stop-
ping the forward motion of the screw and with it the advance of the block to
the cutters; Q, a piece of metal sliding in a vertical frame R; connected
therewith are two spiral springs S, S, for the purpose of more securely holding
the block while being cut; T is an upright plate attached to the table G, and
to which are secured the plane bit and cutters; U is a stationary plane.bit for
reducing any unevenness of the block before its advance to the tubular cutters;
V, a series of stationary cutters or dies for giving form to the splints (seen in
section, Fig. 4 and 5). (Figs. 6, 7, and 8 exhibit one of these cutters enlarged)
e, e, with the lateral wing knives or cutters; f.f, waste escapes for the passage
of shavings; W is a plate attached to the frame T immediately in the rear of
the cutters for the purpose of separating the shavings from the splints.
