This invention relates to a method and means for pressing manufactured tobacco wherein a plurality of pieces of manufactured tobacco such as plugs, twists, etc., can be pressed at one time in a press and then the mass of pressed tobacco can be easily separated into predetermined batches for packing in boxes ready for shipment.

This is accomplished by providing the press heads with a surface which is a reproduction of the surface of a layer of tobacco taken from the inside of a batch of pressed tobacco and also having suitable dividing members for placing between the sections of the tobacco during the pressing operation with both surfaces of the dividng members being provided with a surface which is a reproduction similar to the surface on the press heads.

By carrying out the above described pressing operation the parcels of tobacco appearing between the dividers can be packed in pasteboard boxes if desired.

When the tobacco is to be packed in pasteboard boxes which are unable to withstand back pressure, it is necessary to transfer the batch of pressed tobacco to a second container or hand press such as shown in Figure 3 where it is held under pressure for several days to allow the back pressure to expend itself before the mass is torn down into parcels of tobacco defined by the dividers.

Some of the objects of my invention having been stated other objects will appear as the description proceeds, when taken in connection 2 with the accompanying drawing, in which- Figura l is a side elevation partially in crosssection showing a press in which my improved press heads are used and with my improved dividing members in operation;

Figure 2 is a face View of one of the auxiliary ti@ press heads;

Figure S is a View similar to Figure 1 but showing the container into which the mass of pressed tobacco is placed until the back pressure has spent itself;

Figure 4 is a side elevation of one of the dividing members or members next to the ends of the mass of tobacco in Figura 3;

Figure 5 is an edge View of one of the top or bottom members next to the outer edges of the GL mass of tobacco in Figure 3;

Figure 6 is an edge View of one of the dividing members shown in Figures 1 and 3;

Referring more specifically to the drawing the numerals 10 and 11 indicate the supporting members for the press compartment 12 which compartment has the projections 13 and 14 thereon which are adapted to rest normally on the projections 15 and 16 and the press chamber 12 is a conventional design and has the head members 18 and 19 therein with one of said members 13 and 19 being movable ordinarily and the other of said members being fixed in position, so it is evident that both of the same could be movable if desired. Heretofore it has been the practice to have these members 18 and 19 provided on their inner surface against which the tobacco presses or the plates placed in the press, with a smooth surface, but in my invention I provide the members 20 and 21 which are Secured to the heads 18 and 19 by means of bolts 22 if desired or if desired the members 26 and 21 may be left unsecured to the press heads 13 and 19 and these auxiliary press heads 20 and 21 have moulded on the surface thereof which goes next to the mass of tobacco as shown at 24 the exact reproduction 5 of the surface of an inside layer of plugs of tobacco after the same has been pressed and allowed to remain in a caddy for some time. This surface 24 on the members 20 and 21 is produced by taking an impresson of the surface of an 0 inside layer of tobacco taken from a caddy or pressed tobacco after the same has been coni-ained within the caddy for an appreciable length of time until all back pressure has been spent. In addition to the press heads 20 and 21 I pro- Vide the dividors 25, 26, 27 and 28 to divide the various masses of tobacco, A, B, C, D and E from each other, as it is sometime necessary to pack small quantities of tobacco in small paper boxes and in this way a plurality of these batches of tobacco can be pressed in a press at one time and by having the dividing members 25, 26 and 27 and. 28 between there is imparted to the surfaces of the batch of tobacco a natural rough and ready finish as these members 25 to 23 inclusive have on each side thereof the rough and ready finish 24 which is apparent in Figure 2. This imparts to the outer layers of each of the batches of tobacco A, B, C, D and E the natural rough and ready finish. When the tobacco is pressed in this manner it can be taken from the press which has just been described and. placed into a container 30 which has the bottom member 31 therein which is removably Secured by means of lugs 32 and 33 or any other suitable means and this container 30 has a movable pr ss head 34, and a screw threaded member 35 extending upwardly therefrcm with a handle 36, which screw threaded member 35 penetrates the cross' member 37 which is secured as at 38 and 39 to the side walls of the ccntainer 30, and in addition to the division mem ers 25, 26, 27 and there is also placed in the bottom of this member 30 a member which has impressed on the surface thei-cof which goes next to the tobacco the reproduction of the suriace of an inside layer of pressed tobacco as previousiy described, and also this member being indicated by the reference character 40, and at the top of this mass of tobacco is placed a similar member 41 and When the tobacco is confined within this press 30 for a sufficient length of time to allow the back pressure to be expended then this mass of tohacco is taken from this press and packed in paste board boxes and if desired members similar to to and 41 can be placed in the bottom and top of said paste board boxes 'to insure that the batches of tobacco Will not assume the slick appea'ance roin being packed in the paste board boxes, although after being packed in the paste board boxes it Will have no back pressure as this will aii be expended before it is removed froni the container 30.

In the dra' ing and speoication I have set forth a pret embed cnt of my invention and although specific terms are employed they are used in a generic and descriptive sense only, and not for purposes of limitaticn, the scope of the invention being set forth in the appended ciaiins.

I claim:

1. The method of pressing blocks of manufactured piece tobacco, which comprises placing a plurality of blocks, each block includin a piurclity of pieces, one on top of another With a piate having on one face representaticn of a tobacco leaf at the top and bottom of the pile of blocls and a plate between each two blccks having such representations on both sides therecf, confining and pressing tie entire pile of biocls and plates and subsequently separating the piie Q of blocks into separate block units.

2. That method of pressing pieces of manufactured tobacco which comprises simultaneously pressing pluraiity of batches of tobacco separated froni each other and impressing on the outer surfaces of the batches the surface finish of a layer of pieccs of tobacco taken from the inside of a batch of pressed manufactured tobacco, then placine said batches, undisturbed With relation to each other, in another press and confining the batches in said second press until substantially all back pressure in the batches is spent.

3. That method of pressing and packing pieces of manuactured tobacco which comprises simultaneousiy pressing a piuralityof batches of tobaceo separated froni each other and impressing on the outer surfaces of the batches the surface finish of a layer of pieces of tobacco taken from the inside of a batch of pressed manufactured tobacco, then placing said batches, undisturbed With relation to each other, in another press and confining the batches in said second press until substantially all back pressure in the batches is spent and then separating the batches from each other and paching each batch in a ncn-p'essure applying container.

4. T iat method of pressing and packing pieces manufactured tobacco which comprises the forming of a mass of pieces of tobacco into a plurality of layers and pressing all of said layers simultaneously and at the same time formng on the outer sui-faces of the layers, with suitable dies placed between the iayers, the reproduction of the surface finish of an inside layer of pressed manuiactured tobacco, then separating the layers and packing the layers in suitable non-presapplying containers.

5. method of pressing a mass of pieces of manufactured tobacco which comprises placing in the r ass at spaced intervals dividing members to divide the mass into a piurality of laycrs, applying pressure on the mass to impress on the outer suriaces of the layers the surface finish simuiating the surface finish of an inside layer of pressed manufactured tobacco.

6. That method of pressing manufactured pieces of tobacco which comprises dividing the mass into a piurality of superposed layers and si muitaneousiy pressing the layers to impress on the outside surfaces of the layers a finish simulating the finish of an inside layer of pressed manufactured tobacco.
