To all whom it may concern: sides,thereby moldingor reducing itto square Be it known that I, ROBERT HARDIE, a citiform in cross section. In the construction 'zen of the United States, residing at Brooklyn, shown in Figs. 1 to 7, the mold consists of four Kings county, New York, have invented cerparts, namely, first, a bed 1, upon which the 55 5 tain new and useful Improvements in Cigarrows of loose tobacco are fed in succession by ette-Machines, of which the following is a any suitable conveying or feeding appliances; specification. second, a parallel vertically reciprocating com- My invention relates to machines for makpressor 2, which is moved upward from the ing cigarettes and especially to certain imbed 1, to permit the tobacco to be fed upon 60 to provements in the machine for which Letters the latter, and then moves toward the bed,to Patent were granted to me May 27, 1890, No. compress the mass thereon to the desired 429,031, and my invention consists of certain thickness in one direction; third, a vertical details of construction fully set forth hereinplunger 3, at right angles to the bed 1, and after and illustrated in the accompanying compressor 2, and immediately beyond the 65 I 5 drawings,in whichend of the latter which plunger 3 serves to Figure 1, is a part sectional elevation of sufclose the side of the mold in one direction; ficient of a cigarette machine to illustrate my and fourth, a horizontal plunger 4, movable improvements.

is a top plan view of the folding bars and the To insure the discharge of the rod in proper intermediate pasting disk, showing their relaposition into the receptacle, I prefer to make tive arrangement in the machine. Figs. 14, use of the vertical plunger 3, to carry the rod 15, 16 and 17 are cross sections on the lines downward after it has been pushed from be- 5 14, 15, 16 and 17, respectively of Fig. 13,1ooktween the bed 1 and compressor 2, so as to ing in the direction of the arrows Fig. 18, positively carry down the rod,and to prevent shows a modification of the filler forming the turning of the rod in its descent, I armechanism. range a guard plate 5, opposite the end of the The tobacco compressing means or mold A, bed 1, and extending upward, against which I00 5 maybe constructed in different ways so as to guard plate the rod of tobacco bears as it is compress a row of loose tobacco upon four carried downward by the plunger 3.

The receptacle B, is arranged below the molding devices, in the preferred construction shown in Figs. 1 to 7, in position to receive the rods of tobacco forced downward from the mold, and said receptacle is provided with a channel 00, preferably rounded at the under side, while the edge of the vertical plunger 3, is grooved so that a slight pressure upon the rod when it is in the receptacle, by the action of the plunger 3, will tend to impart a rounded form transversely t0 the rod,but without materially compressing it, the rod in fact expanding slightly when released from the mold,for which reason the channel at, is preferably wider than the cross-section of the rod when in the mold. The rod after being deposited in the receptacle B, is carried longitudinally by the movement of the receptacle, and the succeeding rod is deposited in the latter in such manner that its end overlaps that of the rod first deposited, and the descent of the plunger 3, compresses the overlapping ends of the rods together whereby the succession of rods are connected to form one continuous rod constituting the filler.

The successive rods may be deposited in the channel a", in direct contact with the face of the latter, the wrapper being subsequently applied, but I prefer to convey the wrapper to the receptacle B, folding the wrapper to a U- shape corresponding to the channel :17, and depositing the rods in succession in the wrapper.

The filler or the filler and wrapper together may be conveyed alongthe channel 00, by means of a belt traveling through the channel, in connection with the molding devices above described, but I prefer to dispense with a belt and to employ a continuous traveling receptacle B,in the form of an endless chain, or series of connected links 6, 6, each of which is recessed to form a part of the channel when the links are in line wheels 7, 7, supporting the continuous receptacle and a guide 8, arranged between the wheels maintaining the upper portion of the receptacle in a straight line for a sufficient distance to allow for the folding and pasting of the wrapper as described hereinafter.

The strip of paper 3 constituting the wrapper passes through or beneath a suitable former 9, whereby the strip is folded transversely to a U-shape before or as it enters the channel 0c, the edges of the paper standing above the sides of the channel, as shown in Figs. 3 to 7, and the traveling receptacle to which motion is imparted from any suitable driving shaft carrying with it the wrapper and the filler.

To prevent the tobacco rods from bending down the edges of the wrapper as they are deposit-ed within the latter I provide guards 10, 10, parallel to the channel 00, and extending with their lower edges slightly below the top of the receptacle B, and opposite the sides thereof, so that each rod will be carried down between the guards 10, 10, and will not make contact with the wrapper untilit is below the edges thereof. The guards 10, 10, are supported by brackets 12, attached to the sides of the guide 8.

The links 6, of the continuous receptacle may be of hard material, as metal, or they may be of vulcanized rubber, or the connections may be of metal and the channel portions of rubber vulcanized to. a sufficient degree of hardness to preserve their shape but yielding to asufficient extent to prevent the wounding of the paper wrapper and serving better than metal to maintain such ahold upon the paper as will prevent the latter from slipping.

After the tobacco filler or rod has been deposited in the wrapper one edge of the latter is folded down upon the filler by means of a stationary folding bar 15. This folding bar extends over the top of the channel and has a grooved or concaved under surface 20, inclined downward in the direction of the feed, (Fig. 12) the said bar tapering or being beveled laterally at one side or edge face 61 to a point at the end toward which the wrapper is carried so that the inclined or beveled side orface cl, gradually turns in one standing edge of the paper strip until the same approaches a horizontal position and the paper is gradually carried beneath the lower grooved or recessed and inclined face 10, which latter completes the folding down of the paper upon the -filler leaving the opposite edge standing vertically. The vertical edge now travels past a pastor of any suitable character as for instance a pasting disk 16, Fig. 9 which applies a line of paste upon the inner face of the standing edge after which the latter is brought against the laterally inclined or beveled side or edge face (1', of a second folding bar 17, which face (1 is inclined in the opposite direction from the face (I of the bar 15, and folds down the pasted edge of the paper-strip toward a horizontal position after which a grooved or channeled face to, at the under side of the second will turn the edge of the paper strip completely over upon the infolded edge beneath, and will hold the same in contact therewith as the filler and wrapper travel together until the paste is set and the edges of the wrapper thereby connected together. It will be noticed that the outer lower edge of each of these folding bars has a greater degree of inclination than the corresponding opposite edge owing to the inclined edge or side face d or d, and at the forward end of the bar the said edge gradually vanishes into said side face, while at the rear portion of each bar the two edges of the lower grooved face occupy substantially the same horizontal plane.

The folding bars above described may be used in other classes of machines where there are stationary channels, receptacles or guides and carrying belts. In such case where the belt is employed it will be folded over by the inclined faces and around the wrapper as indicated in'Fig. 10.

It is very desirable and often necessary to IIO remove the folding bars to permit the wrapper to be introduced into the channel or to obtain access in case of the fracture of the paper or other injury and in order to permit this to be done and yet avoid the necessity of repeatedly readj usting and testing the adj ustment of the bars I provide the latter with detachable connections and bearings that absolutely define the position of the bar as soon as it is put in place'so that after it is once adjusted it may be removed and when again placed on its support will occupy exactly the same position it had before. Different ad justing and guiding and securing means may be employed, that shown in the drawings having proved very effective. Thus, each folding bar is secured to an arm 18, projecting from a block 19, provided with a pin 20, having a flat face 12, at one side.

In the frame or guide 8, is a circular socket for the reception of the pin 20, and a set screw 21, which may be brought to bear against the face 1), to fasten the pin in place, and there is also a vertical adjusting screw 22, which atfords a bearing for the end of the pin 20, and determines the vertical position of the latter and of the bar. To prevent the screw 22 from being thrown out of adjustment by the vibration of the machine the bearing or nut 23, through which said screw passes is split Fig. 11 forming t-wo fingers which tend to clamp the screw with a spring pressure and prevent it from readily turning.

The lateral adjustment of the folding bar is effected by securing the arm 18, to the block 19, so as to be adjustable in anysuitable manner, as for instance by screws 24, passing through slots 25, in the arm.

In the modification shown in Fig. 18, the mold A, is constructed substantially as above described, consisting of the bed 1*, the vertically reciprocating compressor the horizontal plunger 3 and the vertical plunger 48. In this instance, however, the open side of the channel 00, of the receptacle B, is ar-' ranged opposite to and in line with the horizontal plunger 3 of the mold, instead of below the latter, the plunger 3*, serving, in addition to its other function, to discharge the tobacco rod from the mold and force it into said channel.

By the use of a continuous traveling, receiver receptacle or conductor I am enabled to dispense with the use of the usual conducting tape or belt, and of the guides which must necessarily be employed in such cases and to this extent can simplify and reduce the cost of the machine as well as simplify the operations of filling, folding and pasting the wrapper. After the filled wrapper passes from the belt or traveling receptacle it is sheared at intervals to form cigarettes by means of any.

suitable shearing appliances not necessary to be here described.

\Vhile any suitable means may be employed for depositing rows of loose tobacco in succession upon the bed 1, of the molding and compressing device I prefer to make use of feeding and separating blades 30, 31, 32, operating above a belt orplatform 33, substantially as described in my aforesaid Letters Patent. The platform 33, may be stationary or it may be as shown, in the form of an endless belt which aids in feeding the material and which belt maybe operated continuously or intermittingly as may be found advantageous.

It will be evident that the improved features above described may be used in connection with each other as set forth,or they may be used separately in connection with other appliances in other forms of cigarette machines. It will also be evident'thatvarious appliances maybe employed for imparting the desired traveling movement to the feeding belt, the channeled receptacle and conveyer and for reciprocating the parts, 2, 3, 4, of the molding and compressing device and as I make no claim to any particular form of actuating devices I do not here illustrate the same.
