MAQHl NE FOR IMPRESSING LETTERS OR MARKS l N CIGARS.

srncrrrcArron forming part of Letters Patent No. 402,467, dated April 30, 1889.

Application filed January 31, 1887. Serial No. 226,000. (No model.)

To all whom it may concern:

of this specification, in explaining its nature.

The object of the invention is to provide 7 means for .automatically presenting cigars to a device or mechanism for impressing in the substance thereof letters, names, trade-marks, or other marks or devices.

It. further relates toa machine having a device for imprinting in the substance of a cigar letters, names, trade-marks, or other figures or marks, and a cigar-feeding device for presenting cigars thereto in successive order.

It further relates to various features of construction and organization, all of which will hereinafter be described.

In the drawings, Figure 1 is a view in perspective of a machine having the features of our invention. Fig. 2 is a plan View thereof. Fig. 3 is a horizontal section thereof on the dotted line :r 00 of Fig. 4. ,Fig. 4: is a vertical section on the line y y of Fig. 2. Figs. 5, 6, 7, and 8 relate to the construction of the re,- lief-die which we prefer to use. Figs. 9 and 12 are detail views. Figs. 10 and 11 illustrate modifications.

The device or machine comprises, first, a cylinder, A, having mounted upon its surface a continuous row or line of impressing dies or molds, A", in relief, which may be of any desired character such, forinstance, as letters, figures, marks, and designs of any kind. These dies or molds are placed upon the cylinder at a. uniform distance apart, and are formed in any desired way, but preferably by means described in our application, Serial No. 226,002, for Letters Patent of even date herewith, and comprisean electrotype-plate having electrotype impression dies or molds formed integral therewith, and this plate is fitted or applied to the surface of the cylinder and its ends secured in the recess a therein by means of a clamping or binding plate, a, which is screwed to the cylinder. The cylinder has the hole a in its bottom and has small holes a in its upper end, and it is adapted to be heated by a lamp placed below it, as represented in the drawings, or by a gasjet, or in any other desired way.

In order that the heat may be brought into contact with the inner surface of the die-cylinder A, we have arranged within the cylinder a deflecting shell or casing, B, which is suspended by its upper end, I), in the chamber formed by the cylinder A, and which is shaped to provide an annular chamber, b between its outer surface and the inner surface of the cylinder A. The lugs 17 (see Fig. 4) hold it concentrically in relation to the inner wall of the cylinder. It will be seen that the heat from the lamp or gas-jet placed as represented in Fig. 1 will enter the annular chamber through the hole a and circulate upward through the same to the openings a and will thus heat the shell or wall. of the cylinder A, which acts as a heatconductor .to conduct heat to the relief-dies.

The cylinder A is mounted upon the hOll': zontal arms C 0'. '(See Figs. 1, 2, and 4.) Thearm C is represented in partly-dotted lines in Fig. 2 and in section in Fig. 4. It, eX tends from the lower flange, c, of the frame 0 to which it is pivoted so as to swing horizontally. Its inner end, or end which fur nishes the support for the cylinder, has an annular upward-extending bearing section, 0', (see Fig. 4,) and the bottom 0 of the cylinder A rests upon its upper edge, and a downwardly-extending annular section,'c surrounds this bearing-ring 0., as shown-in Fig. 4:, This bearing-piece c has a hole of the size of the opening a to the chamber of the cylinder A. The cylinder A is mounted upon this bearing-piece, so as to be rotated or turned thereon. The upper arm or support, 0, is pivoted at c to the upper flange, c of the frame C directly over the point where the lower arm, 0, is pivoted to the lower flange, c, and it is adapted to be moved or swung upon its center with the lower arm for the purpose of adjusting the position of the cylinder A, as will hereinafter appear. Its outer or supporting end, 0 is circular in shape and receives the circular boss or projection extending upward from the cylinder A. However the connection between the end of this arm C and the cylinderA is made it must be so organized as to permit the cylinder to be rotated. This rotation is accomplished by means of the bevel-gear D, which is made in .the form of an annular ring to slip upon the circular extension 0 to be fastened thereto or to the bottom of the cylinder A. There is arranged to mesh with this bevel- -gear D the bevel-gear (1 upon the shaft d,

(see Fig. 4,) which is adapted to be turned by the handle (1 or by power. In the drawingsahandle only is represented. The bevelgear (Z is represented as movable upon the shaft d, to enable it to maintain its connection with the bevel-gear D as the die-cylinder A is moved or adjusted, as hereinafter specified. This contact is maintained by means of a coiled spring, (1 which surrounds the shaft and bears against one surface of the wheel (1 to throw or move it inward toward the inner end of the shaft (1'. The wheel (Z is caused to rotate with the shaft (1 by means of the spline d.

The cylinder A is adjusted horizontally for the purpose of varying the position of its dies in relation to the cigar-holders, so that cigars varying in diameter or size may be treated or impressed by the same machine. This movement is a horizontal one, and is represented as obtained by means of the rod E, which is connected with the arm 0 by a ball-joint, e, and which has at its outer end a screw-thread,e, which enters anut, 6 formed in the arm 6 and extending downward from the frame of the machine. The outer end of this rod E has a thumb-piece, 6 by which it is adapted to be turned. This screw, it will be seen, not only serves to adjust the position of the cylinder A, but also to lock it in any desired place. p

The cigar-feeding mechanism comprises a cylinder, F, which is mounted in the frame C preferably by means of the anti-friction rolls f, fastened to posts f, andupon which a lip or flange, f extending from the outer surface of'the cylinder, is adapted to bear, and the horizontal anti-friction rolls f which are mounted upon the lower frame-flange, c, and are adapted to bear against the outer surface of the cylinder. (See Fig. 1.) This cylinder has upon or in its inner surface the cigar-holders F, (see Figs. 2, 3, and 4,) which are arranged therein at a uniform distance apart, and which preferably are of a size adapted to receive and hold more than half the cigar, taken from end to end, in order that they may properly support the same while they are in contact with the impressing-dies. The cylinder'F is also rotated, and we have represented this as accomplished by means of the bevel-gear G, formed in the lower edge of the cylinder, (see Fig. 4,) and the bevel-gear g upon the shaft d, and its rate of rotation is the same as that of the diecylinder A.

To hold the cigars in their holders after they have been placed therein and while the cylinder F is being turned, we have arranged about the inner surface of the cylinder the stationary holder or guard-plate H, which is concentric throughout its extent with the inner surface of the cylinder F, and which is fastened at its lower edge, h, (see Fig. 4,) to the section h of the frame C and preferably it is secured thereto in a manner to permit of its horizontal movement toward and from the cigar-holders F, in order to permit cigars of varying sizes to be inserted in the holders and be properly held therein while the cylinder is being rotated. This is accomplished by forming a horizontal extension, 7L2, from the lower edge, h, of the guard-plate and forming therein slots 7& for the reception of the fastr ening screws or bolts h. (See Fig. 9.)

The cigars are prevented from falling from their holders excepting at one point by the section or plate h of the frame 0 and the said plate may therefore very properly be termed a cigar-support, as it is beneath the cigar-holder, so that the ends of the cigars rest thereon.

The die-cylinder A and the cigar-feeding cylinder F are so arranged or located in relation to each other that when the machine is in full operation a number of cigars are being simultaneously impressed or acted upon by the impression -dies, (see Fig. 3;) that is, each cigar-holder has its separate die or impressing device, and they are brought together gradually, so that in the operation of the machine the full pressure of one die is upon one cigar while the next cigar in order is receiving an impression from its die, which, however, is not being forced into it with so great pressure, while the third cigar is coming in line with its die. (See Fig. 3.) From the instant that the impression-die and cigar come in contact the die is gradually forced into the substance of the cigar until it is under full pressure, and the cigar-die and cigar-holder continue to rotate until the die is removed from contact with the cigar, when the cigar is released and drops from its holder.

As there may be in some instances a tendency of the cigars to stick in their holders after the action of the impressing-dies, we have formed a device for freeing or stripping the holders from the cigars. This device is represented in Fig. 2 as a spring-arm, M, which is fastened at m by a screw and thumb nut, m, to the upper flange, o of the frame. The spring has an edge which is inclined relatively to the cigar-holder, so that as the cigar-holder is rotated the cigar is brought into contact with the surface of the arm and caused to be moved out of its holder. The position of this spring arm or stripper M is varied or adjusted by loosening the thumb-nut and turning the arm upon its holding-screw.

In order that the cigars may automatically leave their holders after they have been impressed, we have cut away or removed a section of the supporting-plate h, (see Fig. 3,) so that the cigars may drop freely from the machine after the action of the dies and stripper upon them.

In operation the cigars are placed in the holders F one by one, and the holders are moved to present themin successive order to the dies or impressing devices.

It will be observed that the movable cylinder F, with its recesses or holders F for the reception of the cigars, constitutes a movable cigar-carrier to present the cigars to the action ofthe impressing-dies. The cylinder A, on which are mounted the impressing dies of molds, also serves as a movable support for said dies or molds.

In the operation of a machine of this character it is necessary that the impression dies or molds should be heated,because they then act upon the cigar to better advantage, and in some cases, to produce certain elfects, it is even desirable that they should be hot enough to form or produce the design in the cigars by burning or branding as well as by pressure. We have also formed the dies of copper and lead or type-metal, as described in our'said application, Serial No. 226,002, in order that the heat may bereadily conducted to them from the heated cylindrical shell or cylinder which supports them. These dies are shown in detail in Figs. 5 to 8; but as they are not claimed in this application they need not be herein particularly described. It is also desirable that the cigars should be impressed with the intaglio letters, 850., while in temper, and in an application, Serial No. 226,001, of even date herewith, we have described and claimed a process or method which involves this treatment of the cigars.

It is usually necessary for the best results that the impression die or mold should rise or extend from acomparativelyflat 'surface that is, the surface upon either side of the die or mold should be so shaped as not to produce a wedging or splitting action upon the sides of the cigar as the mold or die enters it. The cigar must also be supported practically upon all sides which are submitted to any strain because of the pressure of the die, and this is more than half its circumferencein fact, very nearly two-thirds of its circumference should thus be supported, leaving only a sufficient section exposed to receive the die or mold and the section of the die-plateon each side of the die, sothat upon the application of the die to theexposed surface of the cigar the cigar shall be properly supported against the strain or pressure, which is then necessary-for embedding the die in the substance of the cigar, and is thereby held in perfect shape and prevented from being extended or expanded laterally by the pressure; and where this form of construction or an analogous form for producing the same effect is not employed the pressure is very likely to destroy the cigar by fracturing or splitting the wrapper. I

It will be seen that by making the dies as herein indicated--that is, integral with their This, of course, is very essential,

necessary to quickly substitute dies of one character for dies of another.

It is very essential that the die, shall have not only the letters or marks which it is desired to impress in the substance of the cigar in relief, but that there should be on each side of the die a surface extending therefrom, preferably flat, although it may be slightly curved in, one direction or the other, and which shall hear such relation to the cigarholder that it shall cause the substance of the cigar to be pressed or crowded inward toward the die as it enters the cigar. This action of the die-plate is caused because the cigar is supported by the cigar-holder and prevented from being extended laterally, and

also because fully one-third of the cigar extends beyond the surface of the holder, so that when the surface of the die-plate upon each side of the die comes in contact with the cigar the tendency is to throw or move the substance of the cigar toward the reliefdie rather than toward each surface of the holder, near the opening thereto, and this crowds the substance of the cigar up against the die, so that itis caused to make sharp and well-defined impressionstherein. In Fig. 12 this operation of the die is well shown, and represents the coacting surface upon each side of the relief-die. I

In Figs. 10 and 11 we show a slight modification of the invention, the die-cylinder being represented as separate from the cylin-. drical cigar-feeder in that it is not confined within it, but is placed alongside it, and it is preferably of the same size as the cylindrical feeder. With this modified form the cigarholders will be in the exterior of the feed-cylinder instead of upon the interior, and the guard-plate will of course be upon theouts ide instead of upon the inside of said cylinder. They are also geared somewhat differently,

the shaft of the die-cylinder having a bevelgear which connects it with the operatingshaft, and the shaft of'the feed-cylinder is rotated by means of a bevel-gear, saidoperat' ing-shaft, and a handle. When this form of construction is employed, the surface of the die-block upon each side of the relief-die may be curved to a limited extent.

Having thus fully de'scribed'ou'r invention,
