To all wlw/mit may concern.'

Be it known that we, FRANK Hnnnnv FvANs, a subject of the King `of Great Britain and Ireland, and residing at Wilton (lottage, Beaconsfield, in the county of Buckingham, En land, and HAROLD AGUTTER EVANS, a su ject of the King of Great Britain and Ireland, and residing at 26 Maybank Avenue, South I-Iarrow, in the' county of Middlesex, England, have made a certain new and useful Invention in Fmibossing A paratus, of which the following is a speci cation.

'Ihis invention relates to embossing machines of the kind known as cutter crush machines such as are used for embossing let ters, numerals or designs on cardboard or the like, and at the same time cutting out and punching colored paper or the like into recesses in the cards formed by the dies which latter are necessarily formed with cutting edges. In this way, by using cards of one color and pieces of paper or the like, or one or more card colors, together with suitable dies, the machine can emboss words, letters, figures and designs in any desired color scheme on cards or the like, at one opera.- tion. 'Ihese machines, while adapted for many dihierent purposes, find particular application in the making of show cards, price tickets and the like, for use in shops, places of business and exhibitions.

rIhe object of the invention is to provide a cutter crush machine which is simple of construction, efficient in operation and economical of manufacture.

A further object of the invention is to provide a machine of this character which affords many advantages over machines of other structure designed for the saine or substantially the same purpose.

'further objects of the invention will appear more fully hereinafter.

rI`he invention consists in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawing and finally pointed out in the appended claims.

Referring to the drawing:

Figure 1 is a longitudinal sectional elevation.

Fig. 2 is a transverse sectional elevation. Fig. B is a plan view.

In order to give satisfactory results a a; a chine to be used for the purpose of t invention must be simple in construction and operation, and which should require but' one operator. It should be so veel that'the necessary pressure is in all cases applied with certainty and without due effort: We have found that diderent spes and sizes of dies are required to be impressed into the cards and that ifl the impression depthis insucient the resulting edect is unsatisfactory, while too great a rere will not only frequently spoil the e ect but also cause the dies to wear out very rapidly. Finally, the machine must be so arranged that the pressure is evenly dissipated no matter what the osition of the dies may he.

It is among t e special purposes vof our present invention to provide a machine which answers all of these requirements.

In accordance with our invention, we supply a machine consisting generally of al lower platen mounted on a table pivoted to the frame of a machine, an upper platen in fixed but adjustable relationship to the frame, and a cam shaft mounted in bearings in the frame and adapted to lift the table so that the work may be pressed between the two platens so adjusted that the maximum lift of the lower platen is parallel with the upper platen. We also provide means for adjusting the upper platen to any relationship relative to the frame to suit the thickness of the work or the desired depth of impression. Furthermore, we provide means whereby the dies may be readily changed and the parts requiring cleaning easily gotten to.

Referring to the drawings t atea the table which is pivoted to the bed pte a, asA shown, a convenient distance remote from the center of the pressure application, as will be more fully hereinafter set forth. The lower platen c rests on the table and ia movable backwards and forwards so as to facilitate the setting of the work. For t purpose a light metal frame d' which can be easily handled, is fastened to the platen and extends therefrom along the direction of sliding relative to the table. Any table stop may be employed to detee the position of the platen for the application of pressure. ardened steel p platea e nus, or

lldtl are fastened beneath the tabla and or mally rest on cams formed on the cam shaft f resting in bearings k on the bed plate. ein operating crank g is geared or otherwise suitably connected to the crank shaft.

The bed plate carries four columns to the upper ends of which fasten a brldge iece le adapted to carry the u per platen li 1n order to provide for the a justment of the up er platen, we mount the sameupon the brige piece by means'of springs m, and interpose between the platen and tie underside of the bridge plate, a wedge plate a which may be adjusted in position by a nut o on a stud p secured to the bridge piece, or by other suitable means.

In operation, the lower platen is slid along the table untilit is clear of the u per platen and the bridge piece, the card oard with colored paper, is laced thereon, and the punching and cuttin types are laced in position on the card oard, suita le stops, guides or the like, being provlded on the platen if desired, for the purpose of positioning the work. The lower platen is then slid along the table into its position for the application of the pressure.

The wedge plate n is adjusted so that when the table b has been lifted by the cams 4 into its highest position, the plane surfaces of the two platens c and Z between which the work is pressed, are exactly parallel. 1n order to afford a wide range of adjustment to suit different thicknesses of work, the distance of the bridge piece from the bed plate may be varied by means of suitable nuts 5 secured on the columns z', as shown.

The upper platen having been adjusted to suit the thickness of the work, and the lower platen with the work thereon having been slid into position, the operating` lever g is turned until the cams have lifted the table into its highest position. The cams A4 shown on the drawing are such that the operating lever would have to be moved at least 180 degrees. A suitable stop may be fixed to the fra-me to determine the position of the rest of the operating lever, if desired. The lever 'having ap lied the pressure to the work, thetable rops, the work is removed, and the shaft is then turned to its normal osition without effort. Alternatively, instea of turning the crank shaft towards and away from a stop, it may be made to make a complete revolution.

It will be apparent that it will be easy for a skilled operator to determine by one or two experimental operations what is the correct adjustment of the gap between the .two latens for the particular work and/or ies; the necessary adjustments being made to the wedge fn, by means of the screw o. When the machine has once been adjusted it remains correctly set for repetitions of the same or similar work.

It should be noted that the pivot for the table Z) on the base a and the shaft f are so arranged relative to each other that at the point of maximum lift of the cam the table b is always parallel to the upper platen Z. After the cam. has passed its maximum lift position the table drops which enables the work to be removed and the shaft to be returned to its inoperative position without eifort.

When a large number of cards or the like of the same kind are to be produced, instead of placing the dies on the cardboard. as above described, they may be replaced by a die or dies fastened to the lower surface of the u per platen. In this manner repetition wor is more quickly performed.

It will be readily appreciated by those skilled in the art that the machine forming the substance of our invention, and to which the foregoing description has been directed, possesses many advantages over other previously known machines for the same purpose. By correctly adjusting the gap between the platens the. (proper pressure is applied to the work provi ed the operating shaft is moved through its full distance as the cams must of necessity during this operation reach and pass the position of maximum lift. It is therefore not left to the operator to guess when the correct pressure has been applied. The machine also answers the various requirements above referred to. The wearing parts are quickly accessible. On removing the lower platen and lifting the table by hand towards the upper platen or bridge piece, the cam shaft can be instantly removed from the machine. The pressure plates can then be quickly removed and replaced when necessary.

Many other modiications and changes in details will readily occur to those skilled in the art without departing from the spirit and scope of our invention as defined in the claims, but having now set forth the objects and nature of our invention, and having shown and described a structure embodying the principles thereof, what we claim as new and useful and desire to secure by Letters Patent is:
