This invention relates to hand-operated cigarette-making machines of the kind employing an endless apron passing around two rollers mounted one in each of the halves of a hinged frame or book like casing, the clgarette being formed in the sagging portlon or trough of the endless apron, when such apron is given a to and fro movement around the rollers. t

' In this kind of machine, when the frame is opened or unclosed (like a partly open book), the lateral edges of the endless apron are exposed so that the charge of tobacco cannot be spread evenly in correct form in the trough in the upper run of the apron and especially at the ends of thetrough; the tobacco is in fact liable to fall out from the open ends' of the apron trough and to interfere with the shutting or closing of the frame or book.- Moreover, it is subsequently necessary to cut or trim the ends of the roll of tobacco formed in the apron-trough after the cigarette paper has in turn been rolled around the charge. Further, it has sometimes been found that the endless apron .is damaged if the halves of the frame or casing are-opened out to too great an extent.

According to the present invention, I provide, in a hand-operated-machine with endless apron and of the above mentioned kind, two cover plates or cheek-plates, one at each end of the hinged or pivoted frame or booklike casing. these cover plates bein mounted in such a way that they are substantially at right anglesto thehinge-axis of the frame or casing and that'the cover plates remain in position, adjacent to the lateral edges of the endless apron. whether the frame be closed or open. When the frame or casing is opened out to expose the trough in the endles apron between the,rollers,these cover plates or cheek-plates still protect, or act as closures for, the extremities of the trough in the apron, so that during the rolling oper- 'ation, the ends of the roll of tobacco in the Over the liltemliedges apron adjacent to the ends of the trough when. the charge is. being inserted or rolled or withdrawn.

By means of these cover plates 1 can alsoj limit the outward movement of therollers when .thexcasing is being opened,'-and likewise prevent the. rollers from pressing one against theother when the casing is closed up.

The invention is hereafter described with reference to the accompanying drawin .in

which :Fig. 1 is an. 'endelevation o the machine with the hinged'halves ofthe frame in .the opened position. 'rFi 2 is (a similar 7 view showing the hingedha ves'in the closed osition. Fig. 3 is a planof Fig. 1-' while ig. 4. is a side. view. of the machlner Fig. 5 shows this formof the cover plate detached.

Fig. 6 is an end viewgsimilary-to Fig. 2, but showing a modified form of cover plate. Fig.

he frame of the machine is-shown of rectangular shape and formed. of halvesor members a b hinged to ether at c. Thememspindle d journaled i'rithe end walls a d,

her a is providedwit a roller d'havingna and the member I), is provided. with a roller e having a spindle 'e cjournaled in the end walls b b; and over. these rollers d e which are parallel to 1 one another, rovide an endless apronfof flexible material such as rubberized canvas or. the: like. This apron f, the upper and lower runs of whichware shown in dotted lines in Figures 1 and 2, is

in the trough between the parallel rollers d e, and the charge of tobacco rolledxto' a cylindrical shape by a to-and-fro motion of the endless apron f whengthe frame has been closed up (Fig. '2). The cigarette papeiyin which the cylindrical charge is to bev wrapped, is then introduced into. the casing and this outer paper covering is secured in position in the well knownmanner.

The end walls a a b b are shown in cover plates or'cheek plates su'ch'as h 72 In Figs. 1 to 4, thesev cover plates h h (one of which is shown separately in Fig. 5) areloose m mbers mounted upon the pins or axles d e of the rollers around which the endless apron f passes, and as clearly shown in Figs. 1 and 3, these cover plates h h are located inside the frame itself. Each cover plate is provided with ended slots h for the pins or axles d e at the end of the framehalves, and these two slots k h in .each cover plate h are curved to the centre of the hinge c in the frame or casing. Thus the pins or axles d eat each end of the hinged or pivoted frame a b can travel freely along the curved slots h b in the cover plate It at that end.

The cover plate It may at. its upper edge extend flush with the edges or the frame a 6 remote from the hinges when the frame is closed,-andat the lower edge extend almost to the hinge c, as will be clear from Fig. 2.

The pins d (2 move freely in. the slots h h and the cover plates h '7 remain substantially at right angles to the hinge-axis o of the frame a b, so as to prevent the charge of tobacco from escaping over the lateral edges of the apron f.

An additional advantage provided by these cover plates is that the machine is not limited to shredded tobacco but can work quite satisfactorily with a proportion of tobacco dust, or with tobacco of the kind which is poured from a packet.

The slots 7L h 'also act to limit the outward movement of the hinged halves of the frame or casing. a b so that no undue strain can be put on the endless apron f and a shallow trough or a deeper trough is at all times maintained,whether the frame or casing be open or closed.

The slots 7:. in the cover-plates or endpieces h are so arranged that the movement of the spindles d e therein is limited in order that therollers d 0 cannot come so close together, when the casing is closed, that they exert pressure against one another. If the two rollers could be pressed against each other to such an extent that one bears against the other (even with the interposed apron), the rollers would rotate in opposite directions whereas in the rolling of a cigarette in the apron-trough, the rollers should rotate in the same direction. The slots h h are therefore cut of such alength at their inner "with means for preventing the ro lers from being pressed one against the other when the casing is closed up.

In another form, see Figures 6 and 7, each of the cover plates or cheek plates h is connected integrally with one of the' halves a or b of the hinged frame or casing so as to move therewith and to overlapthe end wall on the other half of the frame or casing upon the inner side. These two integral cover plates are arranged toproject in opposite directions, as shown in Fig. 7. Where the cover plate overlapsthe end wall on theother half of the frame, it may be slotted with a curved :-;lot k1 in which travels the pin or axis of the roller in that half of the frame or casing, so that the opening movement of the casing or frame, is limited in extent. The slots hl are of such a length that theyprevent-the rollers d e from pressing against one another when the casing is closed up, for the reason above explained. V v

The longer walls of the frame or, casing carrying these cover plates for the roll-forming trough maybe ribbed, as shown at iin Figure 4, to stiffen the walls and to prevent the said walls from being dented or crushed when, for instance, the machine is carried in the pocket. 7 It will also be noted from Fig. 4.- that the endwalls a b carrying the hinge pin 0 extend below the side walls of the frame or casing and act as feet or supports when iii: frame is to be placed upon a table or the A cigarette rolled in this machine provided with cover'plates is evenly packed right up to the ends, as if the ends had been neatly trimmed. There is a saving'in tobacco because losses due to an open end of the trough are avoided. Further by reason of the limiting slots in the cover plates, the halves a 6.

cannot be opened so far apart as to strain the endless apron f, and on the other handthe rollers d e are prevented from pressing one against the other when the casing is closed up.

What I claim is: i 1. A hand operated cigarette-making machine, comprising, a casing with two hinged halves, a roller journalled in each ofsaid halves of the casing, an endless apron passing around said rollers and adaptedto form a trough between the rollers for the rolling of the cigarette, and closure members, slidably connected with at least one of said halves at either end of said casing substantially at right angles to the hinge axis thereof adja cent the edges of, the endless apron, for the purpose described.
