page_text: I, TILLMAN PUETZ, Junior of the City of St. Louis, in the State of Missouri, one
of the United States of North America, Machinist do hereby declare the nature of
said 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 to certain improvements in plug tobacco machines; and my
invention consists in features of novelty hereinafter fully described and pointed out
in the claims.
Referring to the drawings A represents the frame of the machine, supporting a
main shaft B in journal boxes B¹. On the outer end of this shaft is a cog wheel B³,
engaged by a pinion B³ on a shaft B' journalled in brackets or boxes B' secured to
the frame of the machine. This latter shaft is provided with a driving pulley B6
through which motion is imparted to the machine.
On the shaft B is a drum C, carrying a number of cams on its outer periphery.
The charger D consists of side pieces D¹, front piece D³, and back piece D³. The
front piece has tongue and groove connection with and is carried by the side pieces
but the back piece is not attached to the side pieces, but moves independently
thereof.
D' are guides for the charger on the table A¹.
Secured to and projecting rearwardly from the back piece are rods E, screw
threaded on their outer ends to receive nuts El and E². These rods pass through a

page_text: cross bar F working on a sliding piece F that works beneath the front and back
pieces of the charger as shown in figures 3 and 6 and forms a bottom to the
charger and a discharging device.
Secured to the outer ends of the rods E by means of the nuts E³ is a cross
head G, having a sliding support G₁ dovetailed into the table of the machine as
shown in figures 4, 7 and 8 and provided with friction rollers G* that bear upon
the table as the charger is worked back and forth. Passing down through this
cross-head is a bolt H, on the lower end of which is a friction roller H¹, engaged
by a cam I, on the periphery of the drum C, to force the charger forward, and
engaged by a cam I, also on the periphery of the drum, to cause the charger to be
moved back.
Figure 5 shows the cam I about to engage the roller to force the charger
forward. Figure 3 shows the cam as it is about to leave the roller, and at this
point it has a portion I³ that is transverse of the drum, the office of which is to
held the charger a short time in its forward position before the cam leaves the
roller.
Figures 2 and 6 show the cam 1¹ before reaching the roller to cause the charger
to be carried back. There is a space I' between the releasing end of the cam I'
and the engaging end of cam I, as shown in Figures 2 and 6, for the passage of the
roller from the former to the latter. As the cam commences the forward move-
ment of the charger, as described, the rear part D³ of the charger is first carried
forward until the tobacco is sufficiently pressed (and the nuts E¹ come against the
cross bar F¹) to move the charger bodily, and when the charger has reached the
position shown in Figures 2, 3 and 6 the plunger J¹ is brought down against
the tobacco on a stationary bed or plate J, as shown in Figure 3. This plunger is
raised and lowered by the following means: L represents a sliding block dove-
tailed into a standard or bed plate L, and connected by means of links L³ to
toggle-bars L³. The upper toggle-bars L³ are pivotted at their upper ends to the
frame of the machine, as shown at L, and are connected at their lower ends to the
lower toggle-bars by a pin Le. The lower toggle-bars are connected at their lower
ends to a vertical sliding rod or beam L' working in slots L8 of the frame of the
machine, and they preferably have slots L'o, through which the rod or shaft passes,
these slots allowing for lost motion, in case lost motion is required.
The rod or beam L' is connected to the plunger by means of two vertical
rods L, passing through guides L1%, secured to the table of the machine, and it
will be seen that as the toggle-bars are forced forward the plunger will be pulled
down to press the tobacco, and as the toggle-bars are pulled rearward back again
from the position shown in Figure 2 to that shown in Figure 5, the plunger will
be elevated again.
M, represents the cam on the drum for forcing the plunger down. Figure 3.
shows the cam M engaging with the projection L¹s on the sliding block, and shows
the parts in the position they occupy just as the block has been forced back to the
limit of its movement to lower the plunger. From this point the cam extends
around the periphery in a line transverse of the drum, and when the drum is
turning the plunger is thus held in its position, giving time for the tobacco to be
thoroughly pressed. This cam ceases at M¹, Figures 2 and 5 and then a cam N
comes against the projection on the sliding block and forces the block and toggle-
bars from the position shown in Figure 2 to that shown in Figure 5 and this latter
cam has a portion. N¹ transverse of the drum, which holds the plunger in its
elevated position until the proper time comes for it again to be depressed, then
the projection will pass through a space O at the end of this cam and the end of
the compressing cam M. Just as the plunger starts to rise, the front end of the
charger is elevated by the following means. K represents a lever pivotted at K¹ to
the frame of the machine, and connected by its outer end to a rod K' made fast
to the lower end of a yoke-frame K³ passing through guides K* secured to the
frame of the machine, and engaged by lugs K on the front part of the charger
(see figure 1) when the charger is in its forward position. This front part of the

page_text: charger has vertical movement from the position shown in Figure 3 to that shown
in Figure 6, by means of its tongue and groove connection with the sides of the
charger. The inner end of the lever K. fits in a cam groove 04 in the front part of
the drum C (see Figures 1, 3 and 6) the groove being annular until it reaches an
offset of and as the inner end of the lever enters this offset its outer end is elevated,
causing the upward movement of the front part of the charger, thus permitting the
plug to be removed from beneath the plunger, which has, as stated, just started to
rise. As soon as the plug has been ejected, the front part of the charger is pulled
down again by the end of the lever emerging from this offset O' in the annular cam
groove.
The plug is ejected by the sliding plate F, which is forced forward and backward
by means of cams P, against which fits a friction roller F10 depending from the
plate. While the plate is in its normal position, the roller fits against the parallel
part of the cam, and when it is to be forced forward the roller comes against a
cam P10, and when the plate F is to be forced back the roller comes against a pro-
jection P of the cam P. (see Figures 2, 3 and 6). The cam P10 is made quite
acute, so that the movement of the plate is rapid, being forced forward just at the
time the front of the charger is elevated, and then being pulled back immediately
before the front part of the charger is again lowered to its normal position. When
the plate is pulled back and the front part of the charger pulled down to its normal
position, the charger is moved back to receive another quantity of tobacco, when
the operation above described is repeated.
It will we seen that the charger, the plunger, the sliding plate for ejecting the
plugs, and the moveable front end of the charger are all operated from a single cam
drum, and as this drum can be cast in one piece at one operation it can be quickly
and cheaply produced, and the form of the drum permits the compressing cam M to
have a long surface that will hold the plunger in its lower position, to give time
for the tobacco to be rendered compact before the pressure is removed. The cams I
and I are made higher than cams M and N, so that the roller H¹ will not have to
be placed so low as to strike these latter cams, yet it is low enough to strike its
own cams I and I¹.
To assist the toggle-bars L³ in lifting, the plunger if required, I pivot two
levers T to the frame of the machine, connected at one end to the sliding block L,
by two links T, and at the other end they extend beneath the rod or beam L'. As
the block is moved from the position shown in Figure 6 to that shown in Figure 5,
the free ends of the levers press against the rod L' as shown.
As a means for stopping the drum at each revolution, to give time for the
charger to be filled, I have shown as part of my said invention a sliding collar U.
on the shaft B which engages with teeth U¹ on the drum C, see Figures 2 and 5.
To the collar U is connected an arm Us pivotted at U³ to the frame of the
machine and connected by its other end to a rod U₁ connected to a lever or
handle U pivotted at Ue to the frame of the machine (see Figures 2, 4, 5 and 9.)
To the lever or handle is also secured a short rod U' that engages a hole Us (see
Figures 2 and 6) in the drum C. The drum is loose on the shaft B and only turns
when the collar or clutch U engages the teeth of the drum. The collar is made to
engage the teeth on the drum by pulling outward on the lever U' compressing a
spring Us that surrounds the rod U between a projection U¹º on the rod and
projection U on the frame A. When the collar is thus made to engage the teeth
on the drum the rod U' is drawn out of the hole U8 in the drum, and the drum
then turns. The handle is then released and the rod U', bearing against the end
of the drum, prevents the spring U from disengaging the collar from the notches
on the drum until the hole Us comes round and then the rod U7 will enter it
stopping the rotation of the drum and the collar is at the same time disengaged
from the teeth on the drum by the action of the spring U°. A positive stop is
thus given to the drum.
To make small plugs, I may provide the plate J with short knives V that will
enter holes or slots V₁ in bottom of the plunger when the latter descends, thus

page_text: cutting the tobacco and making a number of small plugs of one large one, see
figures 10 and 11. The holes V₁ would preferably be provided with rubber or
other elastic material V₁ for the knives to cut against to assist in severing the
threads or fibres of the tobacco. When these cutters are used the plate F should
be slotted to receive them, as shewn in figure 11.
