Improvements in Cigar Headers and Wrapper Stretchers.
I, JOHN BUNN, of Binghamton, in the County of Broome and State of New
York, United States of America, Machinist, 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:-
My invention relates particularly to that part of a cigar machine known as the
wrapper stretcher, and the header or tip former. The wrapper stretcher has
heretofore, so far as I am aware, consisted of a rigid plate convex on its upper
surface in cross section and tapering slightly in both directions from its longi-
tudinal center. It has been found in practice that on account of the gummy
matter in the wrapper, the wrapper leaf will some times adhere to the rigid plate
and be torn as it is drawn into the machine and around the cigar bunch. To
overcome this difficulty I have substituted for the rigid plate a roller journaled
in suitable bearings over which the wrapper is drawn. The roller is rotated by
the friction of the wrapper, and should it become gummed, the wrapper will
separate from it much more readily than it will from a rigid surface and the
liability to tare will be almost if not entirely obviated.
With regard to the head or tip former, in my invention I combine with the
header a conical roller, the periphery of which forms a movable portion of the
interior wall of the tip forming chamber and which is held yieldingly whereby the
chamber is adapted to receive and form different sized tips, and my invention
consists in the several parts hereinafter described and more particularly pointed
out in the claims.
Referring to the drawings:
Fig. 1 is a front elevation of my improved wrapper stretcher and cigar header,
the bunch shaping roller and a portion of the paste reservoir being shown in dotted
lines.
Fig. 2 is a top: and
Fig. 3 is a bottom plan view of the stretcher and header detached:
Fig. 4 is an end view of the header; and
Fig. 5 is a vertical section on the line - of Fig. 3.
Similar reference numerals indicate corresponding parts in each figure of the
drawing.
The bunch shaping rollers are indicated by 1 and the paste reservoir by 2.
The wrapper stretching roller is shown at 3 and the header at 4. The roller 3 is
journaled at each end in suitable bearings 5 and as clearly shown in Figs. 1, 2
and 3, the roller tapers slightly from its longitudinal center in each direction to
its ends, thus presenting at all times a contact surface for the wrapper conforming
in shape to that of the ordinary wrapper stretching plate.
The header 4 is provided with the usual tip forming chamber 6 and the side
opening 7 for the passage of the wrapper to the chamber.
A recess 8 is formed in the lower face of the header and communicates with the
tip forming chamber 6. In the recess 8 the conical roller 9 works and its
periphery forms a movable part of the interior wall of the chamber 6. In the

page_text: lower face of the header a slot 10 is formed extending from the recess 8 to the end
of the header. This slot has an inclined bottom surface the greater depth of the
slot being at its point of communication with the recess. Within this slot 10 is
seated a rectangular shank 11 on a pintle 12 and on the pintle the conical roller 9
is supported to have free rotation. The side 13 of the shank 11 which faces the
hottom of the slot 10, is also inclined in the same direction as the slot, but the
pitch of the incline is much sharper than that of the slot 10 so that while the end
of the shank adjacent to the pintle engages the bottom of the slot its outer end
is separate from it. In the bottom of the slot 10 a coiled spring 14 is seated and
bears against the shank 11 near its outer end. The shank is pivoted on a pin 15
which is secured in the header and passes through the shank at a point between
the pintle 12 and spring 14. It will be seen that the tendency of the spring 14
is to force the conical roller 9 inwardly into the chamber 6 but that the spring
will yield sufficiently to permit the roller to accommodate itself to cigars tips of
varying sizes.
16 represents a passage in the header through which paste is delivered upon the
conical roller 9, which in turn will distribute it over the head of the cigar. The
passage 16 in the header is connected to the paste reservoir by a tube 17.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a cigar machine having a stretcher plate, a wrapper stretcher consisting
of a tapering journaled roller on the inner edge of said plate, said roller being
rotated by frictional contact with the wrapper as the wrapper is fed over the
roller into the machine, substantially as and for the purpose set forth.
2. In a cigar machine, a wrapper stretcher consisting of a journaled roller
adapted to be rotated by friction with the wrapper, as the wrapper is fed over it
into the machine, said roller tapering in each direction from its longitudinal center,
substantially as and for the purpose set forth.
3. In a cigar machine, the combination with a cigar header having a tip forming
chamber and a recess communicating with said chamber, of a conical roller
journaled to rotate in said recess with its periphery forming a portion of the
interior wall of the chamber, said roller being yieldingly supported substantially
as and for the purpose set forth.
4. In a cigar machine, the combination with a cigar header having a tip forming
chamber and a recess communicating with said chamber, a pintle the shank of
which is pivoted to the header, a spring seated in the header and engaging
the outer portion of the shank beyond its pivot, a conical roller supported on the
pintle to rotate in said recess, the periphery of said roller forming a portion of the
interior wall of the tip forming chamber, substantially as and for the purpose set
forth.
