LABELING PLUG-TOBACCO.

SPECIFICATION forming part of Letters Patent No. 254,285, dated February 28, '1882.

Application filed December 19, 1881. (No model.)

To all whom tt may concern:

Be it known that I, DAvID W. DE FOREST, a citizen of the United States, residing in the city ofBrooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Labeling Plug-Tobacco, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of my invention is to overcome certain objections current in various tobaccomarkers in present use, andA to enable the manufacturer to use either metal or non-metallic substances for the purpose of marking plug or other styles of tobacco, and to be known as the Riveting process.7 When a flat piece of metal is used as a label, with projections at right angles with its surface, they perforate the wrapper of tobacco, and the fluid orjuice of the tobaccofiller is lia-ble to ooze out when under pressure and injure the appearance of the plu-g. Should a flat piece of metal be used with designs upon its surface, they do not adhere to the plug reliably without prongs or projections. When cardboard or other materials are used as labels they are liable to be displaced during the. process unless tacked in is aplanview of a plate either of metal or other material, with a hole or aperture through it, as represented at A.

Fig. 2 is a sectional side view through line a w of Fig. l.-

Fig. 3 represents the plate B with plug-tobacco C after pressure, showing the elevation D of tobacco C, having receded or raised into the recess A of plate B by the pressure, and which will be called the rivet.77

Fig. et represents the plug as prepared for the label.

Fig. 5 represents the label F, of any stift' material, provided with a hole, E, of a diameter to pass over rivet D in plug O of Fig. 4.

Fig. 6 represents plug O, with label F over rivet D, and showing rivet D as elevated slightly above the surface of label F and ready for the pressure for completing the affIXing of the label.

Fig. 7 is a plate without hole A of Fig. 1.

Fig. 8 represents plate B of Fig. 7 resting on rivet D, with label Fin position on plugtobacco O for completion by pressure.

' Fig. 9 represents plug O,label F, and plate B after pressure.

Fig. 10 represents the plug of tobacco completely labeled, with label imbedded in the same. y

Fig. l1 is a partial longitudinal sectional view of a finished plug, showing the tobacco overlapping the upper surface of the edges of the label to hold or rivet it.

It will be readily observed that as the rivet D of tobacco is pressed by plate B, Fig. 9, so firmly against the inner circle of the label F, and even overlaps the surface of lhelabel to some extent, as at points Gr, the label is affixed rigidly to the plug without perforating the wrapper.

The process of applying the labels is preferably done in the finishing-pots familiar to all manufacturers of tobacco.

Having described my invention, what l claim 1. A plug of tobacco having a tlat label riveted thereto by a rivet formed of and integral with the body of the plug, substantially as shown and described.

2. The method of attaching labels to plugtobacco which consists in forming a projection on the 4surface of a plug of tobacco, then plac ing a flat perforated label of less thickness than the height ot' the projection over said projection, and then subjecting the plug` to pressure, sov that the label will be riveted to the plug, and so that the outer surface of label,

rivet,'and plug will all be inthe saine plane,`
