rollers 7, 7a and 7b described above, and they
turn in a recess 11C in the face of the cylin-
der. The rollers 11, 113 and 11b are used in
making the second fold, and the paper is par-
5 tially doubled and pushed between the roll-
ers 11 and 11, by a blade 12 on the cylinder
3, this blade being like the folding blade 8
above described.
The roller 3 turns opposite the roller 2 and
io consequently this roller is provided with a
groove 13 to receive the blade 12 of the roller
3 and permit the blade to turn without injury.
On the back side of the lower and last roller 4
is a chute 14 into which the paper is deliv-
15 ered after being twice folded and it is carried
forward against an abutment 15, the paper
being supported on the usual parallel rods
and pushed down between the rods in the
customary manner, so that the final fold, at
20o right angles to the folds made by my folder,
may be given it in the usual manner.
The rollers 7, 73 and 7b and the rollers 11,
11 and 11" are turned so as to give a contin-
uous forward movement to the paper and
25 they may be turned in any suitable way,but
are preferably turned by the gear mechanism
illustrated in Figs. 4 and 5. Here one of the
roller shafts connects by means of a pinion
17 with a fixed gear 18 which is held in a sta-
30 tionary position by supports 19, and the sev-
eral roller shafts are connected together by
gears 173. Consequently as the cylinder 2 or 4,
as the case may be, revolves, the pinion 17
travels around on the periphery of the gear
35 18, and movement is thus imparted to the
several rollers.
Any suitable guiding mechanism can be
employed for leading the paper web between
the several cylinders, and I lay no claim to
40 any mechanism of this kind, but a simple
form of guiding mechanism is illustrated in
Fig. 1. Here the roller 17, which is a common
friction roller, turns close to the lower portion
of the cylinder 2, so that the paper web 16
45 will be fed forward between the said roller
and cylinder. Above the cylinder 2 are ar-
ranged curved finger rods 18, which prevent
the paper from rising from the roller; and be-
neath the cylinders 2 and 3, and immediately
50 above the cylinder 4, is a spring guide 19,one
arm of which presses the paper web against
the cylinder 3. Beneath the cylinder 3 is ar-
ranged a guide 20, which may be composed
of a series of fingers or of a single sheet, and
55 it will be seen that the several guiding de-
vices hold the web snugly against the faces
of the cylinders. As above remarked, how-
ever, any guiding mechanism suitable for the
purpose may be used to direct the course of
6o the web.
The course of the web through the machineis as follows:-The web 16 enters between the
rollers 1 and 2, and when it has traversed the
distance corresponding to the length of a
newspaper, the knife 5 registers with the 65
groove 6 and cuts off the web. The severed
paper is guided between the rollers 2 and 3
and the blade 8 strikes the severed sheet in
the center and pushes its middle portion be-
tween the rollers 7 and 7 which flatten the 70
fold, and the doubled portion is now carried
forward over the guide roller 7b and is caught
by the grippers 10 and carried forward with
the roller 4, and the paper which has been
once folded is made to lie over the rollers 11, 75
11a and 11b and is pushed between the rollers
11 and 1 by the folding blade 12 and it
passes behind the roller 11" and over the face
of the guide roller 11b into the chute14, where
it is taken care of in the inanner already 80o
specified.
Having thus described my invention, 1,
claim as new and desire to secure by Letters
Patent-
1. A paper folder, comprising "a series of 85
three revoluble cylinders arranged to turn in
parallel positions and with their faces adja-
cent to each other, parallel revoluble folding
rollers held to turn in recesses in two of the
cylinders, folding blades carried by the third 90o
cylinder and adapted to project between the
rollers of the other two cylinders, and a cut-
ting cylinder arranged in advance of the first
folding cylinder and having a projecting
blade to enter a groove in the said cylinder, 95
substantially as described.
2. A paper folder, comprising three revolu-
ble parallel folding cylinders arranged in a
substantially triangular position, revoluble
rollers held in the faces of two of the cylin- 1oo
ders, projecting folding blades arranged on
the second cylinder of the series and adapted
to enter between the rollers of the other two
cylinders, and grippers arranged on the third
cylinder of the series and adapted to engage io5
and carry forward a paper delivered from the
first two rollers, substantially as described.
3. In a paper folder, the combination of a
folding cylinder having a recessed face, revo-
luble rollers held to turn in the said recess i o
and'arranged to lie within the face of the cyl-
inder, the inner wall of the recess lying close
to the inner faces of the rollers and serving
as guides for the paper web, the rollers being
adapted to feed a web of paper between them, I r5
and a second folding cylinder having a fold-
ing blade adapted to project between the fold-
ing rollers, substantially as described.
