PROCESS FORPRESSING AND PACKING MANUFACTURED TOBACCO Fii ed Aug. 17, 1929 Patented Dec. 17, 1929 PATENT OFFICE HENRY LP. TAYLOR, OF WINSTON-SALEM, NORTH CAROLINA PROCESS FOR PBESSINGAND PACKING MANUFACTURED TOBACCO Application filed. August 17, 1929.

This invention relates to a method of pressing and packing manufactured tobacco such as plug and twist tobacco, and the object of p the invention is to provide a method and a means of pressing and packing tobacco so as to eliminate-the slick appearance of the end plugs which are prevalent in many forms of packing tobacco. 7

An object of my invention is to provide neans whereby plug and twist tobacco can be pressed in the conventional way with slick press heads in the powerful hydraulic press, and then the mass of pressed tobacco can be placed in a caddy and said caddy placed in 5 another press and the caddy is sealed under pressure with resilient fibrous spongy pads placed between the top and bottom members of the caddy or box and the tobacco and pressure applied so that a rough and ready '0 surface will be imparted to the end plugs of tobacco so that said end plugs will have not only the appearance but also the quality of the plugs taken from theinterior of the mass of pressed tobacco. Another object of my invention is to provide means for pressing and packing manufactured tobacco in caddies, boxes and the like which comprises partially pressing the mass of tobacco in one press and then plac- 6 ing a caddy or box in another press with a spongy, resilient, fibrous pad in the bottom of the caddy or box next to the bottom member of this caddy or box so that this pad will be between the bottom member of the caddy or 5 box and the bottom end plugs of the mass of partially pressed tobacco and then placing the mass of partially pressed tobacco in this caddy or box and then placing another spongy, resilient, fibrous pad on the top end 40' plugs ofthe mass of partially pressed tobacco and then placing the head member of the caddy or box on top of the second spongy, resilient, fibrous pad and then finishing the pressing operation in the second press and sealing this head member of the caddy or box so that even if the mass of tobacco is first partially pressedin a press which has slick heads, as are commonly used, that the final operation of pressing the tobacco in a caddy or box v and sealing the caddy or box, while under which-- Serial No. 386,519.

pressure with the spongy, resilient, fibrous pads next to the tobacco, will cause the end plugs of tobacco to have a rough and ready appearance and simulate the appearance of plugs taken from the interior of the mass of the tobacco.

Another object of my invention is to provide means whereby plug and twist tobacco can be pressed in the conventional way with slick press heads in the powerful hydraulic or power press and then the mass of pressed tobacco can be placed in a caddy, with resilient fibrous, spongy pads placed between the top and bottom members of the caddy or box and the pressed mass of tobacco, and the said caddy or box with the resilient fibrous, spongy pads and pressed mass of tobacco in it is then placed in another press and the head or top member of the caddy is sealed in place under pressure so that a-rough-and ready surface will be imparted in'the end plugs of tobacco resulting in said end plugs having not only the appearance, but also the quality of the plug taken from the interior of the mass of pressed tobacco. 7

Some of the obj ects of my invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in

Figure 1, is a cross-sectional view taken thru the front portion of a press, showing the first step in my process;

Figure 2 is a view of a slightly different form of press in which the tobacco is ready for the final pressing operation;

Figure 3 is a View similar to Figure 2, but showing the second pressing operation completed and the caddy sealed;

Figure 4 is an edge view showing in enlarged scale one of my spongy, resilient, fibrous pads after the same has been sealed in a caddy;

Figure '5 is a view of one of my spong resilient fibrous pads before the same has been used. y

Referring more specifically to the drawings, the numerals 10 and 11 indicate the supports of the press and shows only a portion thereof, and these supports have the projec- 100 tions 12 and 13 thereon on which the pro-- jections 14 and 15 on the press proper 16 are adapted to rest. The upper press head 17 is usually fixedin the conventional press, and the press head 18 is the movable one, this being propelled by hydraulic or other suitable power to compress the mass of plugs of tobacco, which mass of plugs of tobacco is indicated by the reference character 33. This is the conventional type of press in which tobacco is pressed prior to its being placed in another press for sealing, in which second press the caddy or box is placed and into this caddy or box the mass of tobacco 33 is placed for the sealing operation.

In Figure 2 I have shown a conventional type of press used for the sealing operation and into which the caddy is adapted to be placed, and in this type, the reference characters 20 and 21 indicate the supports for i the press, which supports have the projections 22 and 23 thereon on which the projec'tions 24 and25 on the press casing 26 are adapted to fit.

The'caddy'or box 27 is placed inthis press,

' said caddy having-the bottom 28 secured therein'by means of the conventional strips 29 and the fixed press head 30, which is smaller than the caddy is adapted to fit just inside these strips 29. The spongy, resilient fibrous pad 31 is then placedin the bottom of the box and the mass of pressed tobacco 33 is then placed in the caddy, then the second fibrous, resilient spongy pad 32 is placed on top of the massof tobacco, andthen the head member 35 is placed in position, and the movable head 34 of the press is driven down against the head member 35 and pressure is applied to cause the mass of tobacco to be further compressed to assume the condition shown in Figure 3, at which'time the strips 36 and 37 are nailed in place to hold the head member 35 in position, and after the caddy is removed from the press, the other two strips are nailed in position to securely seal the caddy.

The mass of tobacco 33, after beingvpressed in press 16 Figure 1, can be placed with the spongy, resilient fibrous pads 31 and 32, in the caddy or box 27, as shown in Figure 2 either before or'after the caddy or box 27 is placed in press for purpose of pressing and sealing into place head member 35 as shown in Figures 2 and'3.

, IVhi'le I have shown the press heads as being smooth in Figure 1, I desire it to be understood thatmy method can'be used with even better results where the press heads in Figure 1 are uneven, but I have shown the press heads as being smooth for the reason that this is the conventional structure in thousands of presses nowin use, and my in vention is adapted to be 'used in connection with these presses without the necessity of changing the structure of the presses, as this would entail great outlay of capital.

Also, I have shown the mass of tobacco not fully compressed in Figures 1 and 2, and I desire it to be understood that my invention and process can also be used where the tobacco is fully compressed, as when the pressure is relieved the back pressure-will cause the mass of plugs to soonassume the position shown in Figures 1 and 2, and then when the mass is placed in the caddy and the caddy press as shown in Figure 3, the tobacco can be given a greater pull which will cause the outer surfaces of the plugs of tobacco nextto the fibrous pads to impress their surfaces on the fibrous pads and the fibrous pads will in turn imfpress their surfaces on the proximate surfaces of the outer plugs of tobacco and in this way the fibrous pads will act similar 'to real plugs of tobacco, the main difference being in the cost of same, as the,

fibrous pads are made of ground vegetable material, exploded wood, and other suitable material which is very low in price and can be thrown away with little loss.

These layers of fibrous material are really dummy layers of material which act in the same manner :astobacco and may be composed of any suitable material other than tobacco. I

The dummy layers3l and'32 being between theplugs of tobacco and the head members of the'ca'ddy or box in which the tobacco is packed, receive, themselves on their outer sur faces the slick or unnatural finish of the head members in the caddy, and in this way'the dummy layers thoroughly protect, at all'times the outer surfaces of'the end or outside plugs of'tob'acco from having a slick or unnatural finishimpartedto them by the head members of the caddy or box.

In the drawings andspecification I-ha-ve set forth a preferred embodiment of my invention, and although specific terms are employed,tl1e y are used in a generic and descriptive senseonly, and not for purposes of limitation, the scope of my inventionfbeing set forth in tlieappende-d claims.

I claim: f

1. The process of pressing and packing tobacco which comprises placing a plurality of pieces of tobacco in a press and partially pressing the saidflpieces, then placing the partially pressed mass of tobacco in a container with fibrous resilient dummy layers next to the head members ofthe container, placing the container in another press and completing the pressing of the mass of tobacco and sealing the container while the tobacco is under pressure. M

2. The process of pressing. and packing manufactured tobacco which comprisesjprefss- 'nj series of pieces of tobacco in a "press, placing a. dummy layer in caddy, placing the pressed tobacco in the caddy, placing a' dummy layer on top of the tobacco, placing a head member on said last mentioned dummy layer, placing the caddy in a second press, applying pressure thereto, and sealing the caddy While the contents thereofare under pressure.

3. That process of pressing and packing manufactured tobacco Which comprises placing the tobacco in a press, applying pressure thereto, removing the mass of pressed tobacco from the press, placing a fibrous, resilient, dummy layer in the bottom of a caddy, placing the pressed tobacco in the caddy, placing the caddy in a second press, placing a fibrous, resilient, dummy layer on top of the tobacco, placing the head member of the caddy on the last mentioned dummy layer, further pressing the tobacco and dummy layers to a point where the caddy can be sealed by securing the head member in position in the caddy.

t. That process of pressing and packlng manufactured tobacco which comprises placing the tobacco in a press and applying pressure thereto, placing a caddy having a bottom member in a second press, placing a dummy layer of material other than tobacco in the bottom of the caddy, placing the tobacco which has been pressed, in the caddy, placing a second dummy layer of material other than tobacco on top of the tobacco, placing a head member for the caddy on the second dummy layer, applying pressure to the head member and the tobacco and the dummy layers and further pressing the same until the head membar can be secured in the caddy.

In testimony whereof I affix my signature.
