MACHINE FOR THE MANUFACTURE OF CHOCO LATE CIGARETTES.

Application filed March 19, 1926, Serial No. 95,939, and in Germany July 15, 1925.

This invention relates to machines for the manufacture of chocolate cigarettes coinprising a paper casing having a chocolate filling and has for its object to provide an improved machine of this character. According to the invention, rod-shaped pieces of chocolate filling are supplied from a reservoir to recesses formed in the periphery of an intermittently rotated cylinder, each recess being adapted to accommodate one piece of filling, and are then thrust by a rammer, adapted to move longitudinally. from the recesses into paper casings carried by a ladle, the rod shaped fillings before entering the ladle being caused to traverse a cutting member adapted to remove any irregularities from the rod-shaped fillings. It has been ascertained by experience that rodshaped fillings, as supplied from the reservoir are irregular in form, being thicker in parts than in others and occasionally of too great a diameter and even crooked, and it is to overcome this difficulty that the cutting member, through which the fillings are thrust, before arriving at the ladle, is provided. The cutting member removes any irregularities and reduces the fillings to the required diameter. The ladle itself is, according to the invention, composed of a number of thin tongues adapted to be pressed apart by the rod-shaped filling. It is clearly desirable that the filling, should conform, as closely as possible, to the shape of the paper casing, and that this filling should be prevented from sticking as it is liable to, for example, at comparatively high temperatures. Sticking of the filling could readily occur if a rigid ladle were utilized, but this is prevented by using the ladle constructed according to the invention. Furthermore, as a casing could not otherwise be made sufiiciently thin-walled for this purpose and provide a suitably firmseating of the filling in the paper casing, the ladle is so guided as to enter the casing, the rod shaped filling then being thrust into the casing.

In order that the nature of the invention may be more clearly understood it will now be described with reference to the accompanying drawings, in which Figure 1 is a side elevational view in section on the line 1-1 of Figure 2, of an embodiment of the invention, Figure 2 being a plan view in partial section. Figures 3 to 5 are somewhat enlarged views of portions of the mechanism illustrated in Figures 1 and 2. Figures 6 to 8 are enlarged views of the filling ladle.

Referring now to the drawings itwill be seen that the machine constructed in accordance with invention is used in conjunction wlth a casing drawing machine, constructed in a known manner, which supplies a length of easing 1. provided, if desired, with mouth-piece strips, a piece the length of a cigarette being cut off from the length of casing at intervals by shears 2. The empty casings are received by a cylinder 3 which is provided at its periphery with a number of recesses 4, each of these recesses beingadapted to hold one casing (Figures 2 to 5), and the cylinder 3 is rotated intermittently so that the length of easing 1 approaching the cylinder is always coaxial with one of the recesses 4. The casings accommodated in the recesses 4 are'now ready to receive a rod-shaped chocolate filling. which is inserted therein at one end, while the casing in question is held fast by a finger 5 carried by a lever 6, which is actuated by a cam disc 8, secured to a driving shaft 10. through a crank lever 7. The filled chocolate cigarettes are carried downwards by the intermittently rotating cylinder, and prevented by a guard plate 11 in a known manner from falling. out of the recesses 4. finally fall on to an endless moving band 12, upon which they are carried away.

The filling consists of pieces K (see especially Figures 1 and 5 to 8) of chocolate rod of circular cross-section which are located in a reservoir 13, whence they pass out through a passage 14. A cylinder 15 adapted to be rotated continuously by means of pulleys 16 and 17 from the driving shaft 10, is provided, in close proximity tothis passage, for effecting a continuous rotary motion of the rod shaped pieces K of filling so as to prevent the passage 14 from becoming blocked. From the passage 14 the pieces K of filling pass on to a cylin-. der 18 or rather into recesses 19 provided at the periphery of this cylinder. The cylinder 18 is rotated intermittently by means of a thrust rod 20 carrying at one end a roller 21 which engages in the cam vgroove 22 of a cam disc 23 secured to the shaft 10. The thrust rod 20 see Figures 1- and 2) is guided at one end by a member 24 and engages at its other end with an arm 28 of a ratchet wheel and pawl 26 which while preventing any unintentional reverse rotation of the cylinder 18 constitutes a device whereby rotary motion is transmitted to this cylinder.

The rod-shaped pieces K of chocolate filling disposed in the recesses 19 of the cylinder 18 are each inserted by a rammer 27 located in a slider 28 which is adapted to be moved longitudinally on a rod 29, intoits appropriate paper casing. The longitudinal movement of the slider 28 is effected by a thrust rod 30 which is actuated by a crank 31, secured to a crank shaft 32, the latter of which is driven through the pair of toothed wheels 33 and 34 by the driving shaft 10.

A member 35 located between the cylinder 18 and the cylinder 3 and disposed coaxially to the rammer 27 serves to guide the chocolate filling, a cutting device 36' bein attached to the member 35. The rammer 2% thrusts the pieces K of chocolate filling through the member 35 to the cutting member 36, which removesany irregularities from the surface of these pieces and thus reduces them to the required diameter, the chocolate fillin onl entering the casing which may be orme of tissue paper, after it has been thus prepared. During the filling process each tissue paper casing is maintained in its appropriate recess 4 in the cylinder 3 by the finger 5.

Between the cylinder 3 and the cuttigng member 36 is a ladle 37, which is illustrated on an enlarged scale in Figures 6 to.8, and which is carried on an arm 38 of a sliding member 39, the latter of which is adapt-- ed to be moved horizontally on a guide member 40 on the frame of the machine, a lever 41, adapted-to be actuated by a cam disc 42, engaging with the member 39. The ladle 37 is therefore adapted to be moved to and fro in a direction along the axis of the cylinder 3, thus projecting into one of the recesses 4 on the periphery of this cylinder and bein withdrawn from this recess alternately. TVhen the ladle projects into a recess 4 one end of the casing accommodated in this recess is caused to run up on the ladle 37, the other end being pressed against a plane surface 43 which prevents longitudinal movement of the casing.

The ladle itself comprises a base plate having a plate 44 secured thereto, spring tongues 45, of which in the example illustrated there are four, extending through a central aperture in the base plate 37, and being secured to the late 44. The ladle 37 approaches the cylin er 3 and the rammer 27 then thrusts a piece K of chocolate filling through the central aperture in .the base plate ofthe ladle 37. The piece K of filling presses the spring tongues 45 apart (see especially Figures 8- and 7) and enters the tissue pa er casing, the insertion of the pieces of lling into the casing 2 being facilitated by the tongues 45 which are arranged to be sufficiently thin and weak. (dare should be taken that the tongues 45 do not constitute an appreciable obstacle to the motion of the pieces of filling which, consisting as it does of chocolate, has a tendency to stick when thrust through an aperture.

After each casing is filled, the finger 5 is raised and the cylinder 3 continues to rotate intermittently, the filled casings being delivered on to the endless band 12.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what Iclaim is:
