FEEDING MECHANISM.

Specification of Letters Patent.

Patented Jan. 1, 1907.

T0 to whom it may concern.-

Be it known that I, ALFRED SHEDLooK, a citizen of the United States, residing at J ersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Feeding Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to feeding devices for feeding tobacco and other analogous material, and more especially to feeding devices for feeding tobacco to cigar-bunching machines.

Heretofore it has been proposed to feed tobacco to cigar-bunching machines through a chute, trough, or channel which is shaped generally to correspond with the outline of the bunch, the tobacco being caused to move through the channel either by rotating fingers or by reciprocating feeding-fingers which protrude into the channel,and in the construction in which it was proposed to employ the reciprocating feeding-lingers it was also proposed to introduce a spring between the feeding-fingers and their operating devices, so as to prevent the tobacco from being compressed too much in the feeding-chamber, the operating means for feeding devices being such as to give them what is ordinarily known as a four-motion feed.

In the machines which employ a sin le four-motion feeding device, which is yiel ingly operated in the manner before referred to, it has been found that amounts of tobacco for forming bunches of even density would not always be fed forward, because the amount of tobacco in the take of the feeding device would vary, so that sometimes too little tobacco would be fed forward by the feeding device and at other times too much would be fed forward, notwithstanding the yielding character of the connections.

It has been proposed to employ with feeding devices of the character before described a cutting mechanism by which successive amounts or charges of tobacco each sufficient to form a bunch would be severed from the mass and advanced by the feeding device or devices. In certain classes of work, however, it is deemed desirable that the tobacco should be broken from the mass rather than out therefrom.

It is the object of this invention to produce an improved feeding mechanism for tobacco or other analogous material which is of such a character that the material forwarded will be of substantially even density, so that the amounts or charges separated from the mass will be uniform.

' IVith this and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, Figure 1 is a side elevation of so much of a feeding mechanism as is necessary to an understanding of the invention. Fig. 2 is a plan view of the construction shown in Fig. 1. end view, and Fig. 4 is a sectional elevation on the line 4 4 of Fig. 1.

Referring to the drawings, 1 indicates a frame, which may be of any suitable coniiguration or construction. This frame serves to support a channel 2, through which the mass of tobacco is fed, said channel when the device is used for feeding a mass of tobacco from which charges which are to form bunches are separated being preferably given a concave shape, generally corresponding to the outline of the bunch. This channel may be formed in any suitable manner, but, as shown, is formed from a casting or plate having depending lugs 3, which are provided with projections engaging grooves 4 in the frame of the machine. In the preferredform of the construction the channel will be provided with a slotted top. As shown, this top consists of wires 5, said wires being connected to cross-bars 6, which are suitably secured to the frame of the machine. The ends of these wires in the preferred form of the construction are bent upwardly, as indicated at 7, to form a flaring mouth for the entrance end of the channel. I

The tobacco may be fed through the channel by mechanism varying widely in character. In the preferred form of the construction, however, two or more feeding devices will be employed, said feeding devices being arranged tandem. These feeding devices may be variously mounted and operated. In the construction shown, which illustrates a preferred form of the apparatus, there is pro- Fig. 3 is an I vided a guideway which comprises a pair of horizontal rods 8, extending along above the channel, these rods being mounted on standards 9, rising from the frame. On these rods are mounted carriages which may be of any suitable construction. As shown, they comprise plates 10, which extend across the machine, said plates having depending webs 11 and 12, which are perforated and through which the rods 8, which form the guideway, pass.

For reasons which will appear hereinafter it is desirable in some cases that there be con siderable friction between the carriages and the guideway. This friction may be provided for in any suitable manner. As shown, each carriage is provided with a pair of springs13, which bear upon therods 8, forming the guideway, the amount of pressure of the springs being regulated by means of setscrews 14 or in any other suitable manner.

The feeding devices proper may be, as has been before indicated, of widelydiffering constructions. As shown, they consist of a plurality of sets of fingers 15, there being one set of fingers for each carriage. These fingers are mounted in the construction illustrated on cross-bars 16, which move in guideways formed in the webs 11 before referred to, the construction being such that the bars can be reciprocated to cause the fingers to move into or out of the mass of tobacco or other material in the feeding-channel. The vertical movement of the fingers may be effected by any suitable construction. As shown, each carriage is provided with bearings 17, which serve to support shafts 18 extending across the machine from side to side. Each of these shafts 18 has secured to it a pair of arms 19, these arms having concave recesses in their ends which engage pins 20, carried on upward extensions of the cross bars 16.

In the preferred form of the construction the feeding devices will be first moved into engagement with the mass of tobacco or other material in the channel and will then be given a forward movement. After they have completed their forward movement they will be withdrawn and returned for a fresh take. The forwarding movement of the feeding devices will furthermore be effected in such a manner that this movement will cease when ever the tobacco or other material in the feeding-channel has been compacted to a certain predetermined degree.

The described feeding movements of the feeding-fingers or other feeding devices may be effected by mechanism of any suitable character; but in the construction shown they are effected by interposing a yielding connection between the carriages which carry the fingers and the operating means therefor. The operating means referred to may be of any desired character. As shown,

there is provided a slide which comprises two horizontal bars 21, which move in ways in the standards 9 before referred to. These bars 21 in the construction shown are connected by links 22 to operating-arms 23', mounted on a shaft 24, suitably supported in bearings in the frame of the machine and ex tending across the frame from side to side. One of these arms 23 is provided with an eX- tension 25, to which is pivoted a link 26, said link being connected at its other end to a crank-pin 27. This crank-pin 27 is carried on a crank 28, said crank being mounted on a shaft 29, suitably supported in the frame. This shaft 29 is provided with a gear 30, which meshes with a ear 31, mounted on a shaft 32, which will behereinafter referred to.

The connection by which the feed-slide 21 moves the carriages in the manner heretofore referred to may be ofany desired construction. As shown, each bar 21 is provided with apair of links 33, which are connected to arms 34, loosely journaled on the shaft 18, before referred to as mounted on the carriages. The movements of the slide-bar roduced by the mechanism before described are of course positive, and in order that the carriages may be stopped in their feeding movement Whenever required by the density of the mass in the feeding-channel without affecting the movements of the slide the connection between the arms 34 and the shafts is a yielding connection. As shown, each shaft is provided with two springs, the springs 0n the shaftnearest the delivery end of the channel being marked 35 and the springs on the other shaft being marked 36. The springs 35 are wound around their shaft and are connected at one end to collars 37, which are fast on the shaft. The springs 36 are similarly wound about their shaft and are fast to collars 38, secured on the shaft. The ends of the springs 35 which are not fast to the collars are carried upward and over pins 39 on the arms 34 with which they cooperate, and the ends of the springs 36 are similarly secured to pins 40 011 the arms 34 with which they cooperate. Each arm 34 is provided with a forwardly-extending toe 41, which takes under pins 42, mounted on the arms 19 before described. With this construction it is apparent that as the arms 34 begin to move under the action of the slide the springs will rock the shafts 18 and cause the feeding-fingers through the connections described to engage the mass of material in the feeding-channel, the carriages at this time remaining stationary through their own inerti a, assisted by the operation of the springs 13 before described. WVhen the feedingfingers have become fully engaged with the mass in the channel, the shafts 18 will cease to rotate, and the further movement of the slide will cause the carriages to be advanced. This advancing movement of the carriages will however, stop whenever the density of the mass in the channel is sufiicient to overcome the tension of the s rings and 36, at which time the slide Wlll continue its forward movement, although the carriages remain stationary.

It will be furthermore seen that although the forward carriage may cease its feeding movement the rear carriage may continue its movement. This insures a ractically uniform density of the mass in t e channel behind the forward feedingfingers, so that these fingers when they are retracted for a fresh take will be sure to receive a full charge.

In the preferred form of the construction the springs 35 will be made slightly stronger than the springs 36, so that the compacting action of the two sets of feeding-fingers is progressive.

The tobacco may be placed in the channel and within the range of action of the feedingfingers in any desired manner. As shown,

there is provided afeeding-belt 43, said belt passing over a drum 44 on the shaft 32 before described. In the construction shown this belt not only serves to forward the tobacco, but also drives the shaft 32.

In order to insure that the mass of material completely fills the feeding-channel from side to side and at the same time does not extend beyond it, there is preferably provided a suitable cutting mechanism, which, as shown, cooperates with both sides of the channel. This cutting mechanism in the construction illustrated consists of a pair of rotating knives 45, said knives being fast on a shaft 46, which is driven by means of a belt 47 from a belt-wheel 48, mounted on the end of the shaft 29 which is opposite to that which carries the crank.

The mechanism for separating the successive charges from the mass of material fed through the feeding-channel may be of any desired description. In the preferred form of the construction, however, this mechanism will operate to break the charges of tobacco from the mass as distinguished from cutting them therefrom. The breaking mechanism for separating the successive charges may be widely varied in construction. As shown there is provided a breaker which consists of a comb 49, said comb being carried by a plate 50, which is fast on a shaft 51, suitably supported in the frame. This shaft 51 has connected to it an arm 52, which is in turn connected to a link 53. This link 53, is provided with a cam-roll 54, which works in a cam-groove in the face of the wheel 48 before referred to. The extreme end of this link 53 is provided with ayoke 55, which takes over the end of the shaft 29, so that the link is suitably supported.

To assist the breaker-comb in its action, a suitable holding mechanism is preferably provided. This mechanism may be of any able character.

its rearward movement.

suitable description. As shown, it consists of a series of holding-fingers 56, carried on a suitable cross-bar 57. This cross-bar 57 is carried by the arms 58 of two two-armed levers 58 59, which are loosely pivoted on the shaft 51 before referred to. In the construction shown these two-armed levers are operated through suitable connections from the slide before referred to. The connections by which the movement of the two twoarmed levers is effected may be of any suit- As shown, each of the bars 21 which comprise the slide has connected to it a link 60, said links being provided with slots 61, which engage pins 62 on the arms 59 of the two-armed levers.

The movements given the slide in the construction shown in order to enable it to operate the carriages are greater than is necessary to produce the necessary operations of the holding-fingers. ment of the fingers may be interrupted without interfering with the movements of the slide, each of the links 60 is provided with a tappet 63, pivoted at 64 and having operating-faces 65 and 66. The tappets are held in operative position by means of spring-operated blocks 67, which bear on the tappets, said blocks being carried, on standards 68, rising from the links. There is also pro vided a stop-pin 69, which in the construction shown extends from the forward standard 9; With the construction described as the slide begins its movement (see Fig. 1) the two-armed levers 58 59 will be operated by the tappets, the faces 65 ofwhichbear against the pins 62. Then, however, the bar 57 strikes the pin 69, the tappets will be rocked and allow the slide to continue its movement without moving the fingers. When the slide has completed its forward or feeding movement, the faces 66 of the tappets will be in engagement with the pins 62. On the return movement of the slide the levers 58 59 will be operated to throw the holding-fingers down into the mass which has been forwarded by the feeding-fingers, and after the holding-fingers have become fully engaged with the mass the tappets will again be rocked, thus permitting the slide to continue The movement of the breaking-comb is of course so timed that it comes into action after the holding-fingers have become fully engagedwith the mass.

There is preferably provided a deliverychute, through which the breaker comb forces the charge which has been torn from the mass. This delivery-chute may be constructed in any suitable manner. As shown, the front wall of this chute is formed by bending down the forward ends of the wires 5, said downwardly-bent ends being marked 70. The rear wall of the chute is or may be formed by wires 71, which are or may be fast to the frame.

In order that the move- IOC In order to support the forward end of the mass of tobacco as it is fed forward by the feeding-fingers, so that the charge torn from it by the breaker may descend the deliverychute in a comparatively compact condition, there is preferably provided a gate, which may be of any suitable construction. As shown, this gate consists of a series of fingers 72, which are carried on a cross-bar 73. This cross-bar 73 is carried by arms 74, which are loosely mounted on the shaft 24. The arms 7 4 are held up, so that the gate will be in operative position by means of a spring 75, which surrounds the arms 7 4, one end of said spring being secured to one of the arms 74 and the other end being secured to a pin 76, which is fast on the inside of the frame. In order to prevent the arms 74 from rising too far, one arm is provided with a toe 77, (see dotted lines in Fig. 1,) said toe being so arranged as to strike the pin 76 when the arms and gate are at the limit of their upward movement.

While the machine which has been described illustrates a preferred form for carrying the invention into effect, it is to be understood that the invention may be em.- bodied in constructions which differ widely therefrom. The invention is not therefore to be limited to the exact construction herein shown and described.
