COMPLETE SPECIFICATION.
Improvements in Automatic Cigar-tip Cutters.
We, EDWARD BRUNHOFF, Manager and Manufacturer, and CHARLES LEHMAN,
Manufacturer, both of 126 East Court Street, Cincinnati, Ohio, in the United
States of America, 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, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say :-
Our invention relates to improvements in automatic cigar tip cutters.
One of its objects is to provide an improved cutter operated by a spring or other
suitable driving mechanism to automatically cut off cigar tips.
Another object is to provide suitable tripping and stop mechanism for the
same.
The features of our invention will be more fully set forth in the description of
the accompanying drawings forming a part of this specification, in which :-
Fig. 1, is a central vertical section through the cigar tip cutter and operative
mechanism located therein.
Fig. 2, is a side elevation of the operative mechanism and its supporting frame.
Fig. 3, is a top plan view of the same.
Fig. 4, is a perspective view of the wheel carrying the cutter knives.
Fig. 5, is an enlarged central vertical section through the same.
Fig. 6, is a bottom plan view of the plate and lugs against which the stop
mechanism engages.
A represents the cutter wheel armed with one or more knives a and journaled
by means of a shaft B in a frame C. D represents a shaft likewise journaled in
frame C and carrying-a-spur-gear-E-which engages and drives a spur gear F on
the shaft B, in order to rotate the cutter wheel.
G represents a spiral spring one end of which is looped over the stud g, while
the other end is secured to shaft D. d represents a wrench or key seat by means
of which shaft D is turned to wind up the spring.
H represents the tripping boss, which seats in a recess in the cutter wheel
and is held in position by means of a spiral spring h seating in a socket at its
inner end.
I represents cross arms extending from opposite sides of boss H and seating in
slots i, cut in the opposite faces of the cutter wheel. The rear end of the knife is
cut out in a semicircle around the boss H, and its rearwardly projecting arms form
bridges across the slots i, to limit the outward movement of the boss H and cross
arms I.
J represents lugs or stops projecting downwardly from the under face of
plate K, upon opposite sides of the cutter wheel and against which the cross arms [
strike or engage to stop the rotation of the cutter wheel.
The operative parts are secured in the case in the following manner: The top
plate L is secured to the plate K by means of screws passing through lugs 1. The
shell M is secured to the frame C by means of screws passing through lugs m.

page_text: cut off a cigar tip, the tip is pressed upon the head of boss H through the
opening N. As the cigar tip is pressed against the boss H, the boss yields
compressing the spring h, and carrying arms I downwardly until they are free of
the lugs J when the wheel A revolves rapidly bringing the knife around to cut off
that part of the cigar tip projecting through the opening N, after which the arms I
which follow the knife engage with lugs J and stops the wheel with the boss H,
closing the opening N, after which it may again be released in the same manner.
I have shown two knives and sets of tripping mechanism upon the cutter wheel,
but a less or greater number may be employed if desired.
a¹ represent grooves cut in the face of the cutter wheel behind the bosses H,
into which the cigar tip projects as the cutter wheel commences to revolve.
It will be observed that centrifical force as well as the spring h tends to hold
the boss H in its outward position causing it to act reliably and quickly, and the
cross arms I simultaneously engaging lugs upon opposite sides of the wheel, relieve
it of any tendency to torsional strain which would occur if a stop were used upon
one side of the wheel only.
It will also be observed that the wheel A being made in one piece and having
the bosses H inserted in the body thereof makes the device stronger and better
able to resist the strain.
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 a cigar tip cutter, the combination with a case baving an opening for the
insertion of the cigar tip, of stop lugs arranged upon the opposite sides of said
opening, a power driven cutter wheel journaled in fixed bearings and provided with
a radial recess, said cutter wheel being adapted to rotate beneath said opening, a
radially movable spring actuated tripping boss seated in said recess, laterally
projecting arms on the opposite sides of said tripping boss operating to simul-
taneously engage the said stop lugs, and a knife fixed on the cutter wheel in front
of the tripping boss and provided with rearwardly extending arms projecting
across the said recess and operating to limit the outward movement of the tripping
boss, substantially as described.
2. In an automatic cigar tip cutter, the combination with a case having an
opening for the admission of the cigar tip, of stop lugs arranged upon opposite
sides of said opening, a solid power driven cutter wheel, a radial recess in the
body of said wheel, a spring arranged in said recess, a tripping boss seated in said
recess on said spring, laterally projecting arms on opposite sides of said tripping
bose, said arms projecting through radial slots formed in the cutter wheel and
operating to simultaneously engage said stop lugs, substantially as described.
