IMPROVEMENT IN MACHINES FOR MAKING CIGAR-BUNCHES.

Specification forming part of Letters Patent No. 140,860, dated July 15, 1873; application filed July 8, 1872. I v

To all whom it may concern.-

Be it known that I, DANIEL A. WIGHTMAN, of East Greenwich, in the county of Kent and State of Rhode Island, have invented an Improvement in Machines for Making Gigar- Bunches, of which the following is a specification:

The nature of my invention consists in so controlling the movements of two or more separatelyacting feeding devices arranged to force the tobacco forward to the knife and sizing-chamber of a cigar-machine, that the action of one of the independent feeding devices will not so affect the movement of the one next in succession toward the knife as to prevent the desired uniform action upon the tobacco in the sizingchamber. My invention also includes an improved mode of constructing and operating the receiving and discharging chamber for sizing the fillers. It also consists in a tobacco-feeding device composed of spur-disks arranged alternately with the necessary intervening bars upon the same shaft, the said combination constituting a desirable feed-roll, and in addition thereto providing for one side of the throat or passage through which the tobacco is forced into the sizing-chamber. I,

Figure 1 is a sectional side view of a cigarmachine as arranged to illustrate my improvements. Fig. 2 is a front view of the same. Fig. 3 is a side view. Fig. 4: is a partial view of the side opposite toFig. 3. Fig. 5 is a partial longitudinal section and top view of the combined spur roll and bars. Figs. 6 and 7 are side views of one of the bars and a spurdisk, of which the combined spur roll is formed.

In the drawing, A A is the frame of the machine. B is a hopper, into which the loose tobacco may be first placed. 0 (l O are spur-rolls made to revolve by means of the weights D and D operating through the ratchets E and E to produce a uniform pressure in a sizing-chamber from a variable movement in the feeding device, as set forth and claimed by me in an application for a patent filed November 21, 1872. The weights 1) and D may be raised preparatory to their action upon the rolls by means of the slotted bars F and F? connected to the outer end of the rocking-arm Gr. To the slide J is attached the knife j used to cut off the required quantity of tobacco to form a cigar, and also to retain the tobacco in the throat or passage H while the chamber I is being thrown open in order to remove the inclosed filler. The slide J may be operated'by means of the connecting-bars K K, cranks L L and L upon the shaft M and the bar N with a pin, a, operating in the groove of the cam o placed upon the-shaft P, or by other suitably-arranged de-' vices.

The machine shown for rolling on the binders is similar in construction to those hereto- .fore used by others for this purpose, and its operating-jaw Q may be closed upon the filler by the action of a suitably-arranged spring or weight. I

The opening of the machine against the closing action of the above-mentioned spring or weight for the purpose of discharging the finished bunch and receiving a fresh filler, as

represented in Fig.3, may be readily effected by means of the bar S connecting with the rocking-lever T, which is operated by meansv of the barUand pin a, in connection with the cam V, upon the shaft P. The slides W W arranged upon opposite sides of the machine within the frame A A are connected to each other by the bar X, which forms the top of the chamber I, and also by the rod Y. To the slides W W is also hinged the jaw Z forming two other sides of the chamber 1, and to which is attached the arm a provided with a pin, b, engaging with the cam-slide 0. Upon sliding back the chamber I, as shown in Fig. 3, and thus allowing the pin 1) to come in contact with the cam surface a, the jaw Z will be thrown open and the inclosed filler dropped from thence into the binding-machine.

By the employment of a chamber, I, an ranged to draw directly back from the knife in opening to release the tiller, there is great danger of dropping some of the smaller pieces of tobacco on the way to the binding-machine I therefore arrange a cam-surface, c, which Frrcn.

will operate to cause the jaws of the chamber to be more tightly closed upon the tobacco to retain it as soon as the chamber has been started from the knife, the pressure being continued until the jaws are thrown open by the action of the cam-surface 0 upon the pin 1).

The sizing-chamber I maybe held to its seat against the knife, as shown in Fig. 1, by means of a spring or weight arranged to exert its force in the direction of the arrow 6, or by a suitable cam, and may be thrown back to discharge its load in timely relation to the action of the knife or gate j, by means of the bar f forming a connection between the rocking arm T and the rocking-lever h, which is pivoted upon the shaft P, the outer end of the lever operating to move the slides W W against the action of the before-menijsifoned spring or weight by striking the rod As preferably arranged, and as shown in the drawing, the jaws of the binding-machine will be about half opened at the time the chamber I first commences to receive its backward movement, for the purpose of discharging the inclosed filler.

The spur-rolls O O and O are formed of separate disks 0 O, which, with the intervening bars k k, are held upon a shaft, m, as

.shown in Fig. 5, the bars 70 70 being held loosely, while the disks 0 (J are secured so as to turn with the shaft, by means of the pins 11 v, which enter the slots 10 w. Fig. 6 shows a side view of one of the intervening bars k, when made in suitable form, to be used for the top of the throat or passage H. The thickness of the bars and disks may be from one-eighth to one-quarter of an inch, as deemed most desirable.

When the throat or passage H is filled with tobacco, which is acted upon by several rolls at the same time, a difficulty is experienced, in causing the rolls to turn properly, from the fact that the spurs do not sink into the mass in the direction of their points, but more in the direction of their sides, the previously-compacted tobacco exerting a considerable resistance to such penetration; I therefore arrange to prevent the action of each alternate roll, in a series, by means of suitable devices operated in timely relation to the opening and closing movement of the knife or gate j, and thus the roll 0 nearest the knife, will not be crowded or obstructed in its proper movement by the action of the roll 0 which would be the case were they both allowed to act upon the tobacco simultaneously.

When the knife or gate j is down, as shown in Fig. 3, the pawl o, engaging with the ratchet 19, will prevent the forward movement of the roll 0 but the pawl 0 being at the same time raised by the pin q of the bar K out of contact with the teeth of the ratchet 0 allows the roll 0 to turn so as to force the filling along the curved portion of the passage H into the space between the rolls 0 and 0 but, when the gate j is afterward raised, the pin q will strike the pawl 0, disengaging it from the teeth of the ratchet p, and the corresponding upward movement of the pin q will allow the pawl o to strike down into the teeth of the ratchet p. The operating movement of the roll G being thus effectually checked during the time that the gate j is raised will allow the forward roll 0 to draw the tobacco from a state of rest in the passage H, thus permitting the spurs to act freely without being subject to the crowding action of the roll 0 as heretofore experienced. The tobacco in the sizingchamber will therefore be influenced only by the weight D, which operates the the roll 0 producing the uniform pressure in the sizingchamber desired.

The same object may also be attained by means of pawls placed between each roll of the series, and operating directly upon the tobacco in the passage H. Such an arrangement is shown in Fig. 1, where the gate j will operate as a sufficient stop for the roll 0 and the pawl r for'the roll 0, it being attached to the lever s, and so controlled by the pins t it, upon the slide J, that whenever the knife is raised, so that the roll 0 can be allowed to turn, the pawl 1' will be thrown down into the tobacco between the rolls 0 and 0 thus preventing the movement of the roll 0 and the consequent crowding or choking of the roll 0 The principle above illustrated, for securing a uniform pressure in the sizing-chamber of a cigar-machine, is capable of application to a variety of devices'for feeding tobacco; I do not therefore restrict myself to the use of spur-rolls in this connection, but include in my claim its application to control the action of any series of feeding devices, whose joint and simultaneous action may, when unrestricted, produce a greater pressure in the sizing-chamber than when such action is limited to a single one of the series. I am thus enabled to guard the tobacco in the sizingchamber from undue pressure in extending the system of variable separately-driven rolls, or other feeding devices, to the full extent desired in any case.

The chamber I, instead of being attached to the slides W W, may be arranged to swing in the arc of a circle, the cam-slide 0 being in such case correspondingly curved. The movable jaw Z may also be hinged at the point y instead of the point no, and thus form but one side of the chamber 1 instead of two, as represented in the drawing.

I claim as my invention- 1. The feeding-rolls G and G or any equivalent feeding devices, in combination with-a throat or passage, H, and knife or gate, 3', when the said feeding devices are controlled in their forward movements in such a mannerlthat one of them will be caused to oper= ate when the gate is raised, and the other when it is down, substantially as described.

2. The sizing-chamber I, with .a hinged lower jaw, in combination with the arm a, pin b, and the cam-slide 0, or their equivalent, operating substantially as described.

3. A throat or passage, H, when formed either on one or both sides by the bars k k, arranged between the spur-disks C 0 upon a a shaft, m, substantially as described.
