EMBOSSED-PRINTING MACHINE,

Application filed June 23, 1925. "Serial No. 39,084.

This invention relates to machines for producing printin to simulate engraving or embossing, and t e said invention has for an object the provision of novel means whereby multicolor printing may be done; the said printing while in a moist state being coated with a powder or granular material which is afterwards subjected to heat after the process well known in the art in which embossing machines are employed.

It is a further object of this invention-to produce a printin device of the character indicated in association with a supply of material to be printed, and in which the material is drawn through the printing apparatus in the form of a web; and the said device includes means for imparting motion to the web in a step by step travel, so timed as to permit the printing mechanism to operate successively on the web as it is passed through the printing machine so that multicolored plrinting can be done when desired, althoug of course, the same features may be employed where one color ink is being distributed or used.

Furthermore, it is an object of this invention to provide a coating means through which the web is drawn after it is printed, whereby the printed surface is provided with a deposit of any of the well known or special coatings that are melted or partially melted when subjected to heat, for the purpose of producing the raised or embossed" effect; and

it is furthermore an object to associate with.

the last mentioned means an agitator or tapping device which will be operative to dislodge excess deposits of the aforesald material from the web prior to the time it is subjected to heat, as will presently appear.

It is a still further object of the invention to provide a suitable guide and drawing rollers which pull the web through the printing apparatus and the coating applying means in order that the said web may be delivered to a cutter which will sever the web into appropriate lengths to produce cards of different sizes or sheets of material that have been treated.

It is a still further object of this invention to provide novel means for operating the cutter in time with the drawing rolls and the printing mechanism.

It is a further object of this invention to produce a conveyer and, furnace or oven effective to j ct the eie e a d t e t d. and

intense heat.

heat the cut sections of web and the de-' posits thereon so that the same will be hardened, as 15 done in machines of the character mentioned.

It is furthermore an object of this inventionto produce a heater or oven, through whlch a conveyer travels for carrying the printed and cut material, and in order that the deposit may be properly baked without in ury to the card, or the cardboard (the same to be hereinafter referred to as cards, the sald term being understood to mean any stock in the nature of cardboard, aper or the like bearing the deposits), it Has been found in practice that it is desirable to subect the said cards to the action of comparatively intense heat intermittently and to maintain the temperature of the cards in a heated state between the zones of the more By the arrangement just stated, the heat is not sufiiciently great to impalr the cards or scorch them, while at the same time, the deposits areproperly heated so that they set and remain hard.

It is astill further object of this inventron to produce novel means for regulating the temperature of the oven by the employment of sectional heaters which may be controlled in sections to produce the desired temperatures, and the said heating device, which is in the nature of electrical resistance coils, may be expeditiously and inexpensively repaired, since each resistance elementis of short length separately installed.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, ref-- erence will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation showing a printing device associated with a coating device;

n these drawings, 15 enotes a printing press having multicolor distr buting rolls 16, 17, 18 and 19 that operate in conventional manner with respect to the type, and other parts of a printing press wh1ch need not, it is thought, be described 1n detall.

A bracket 20 rotatably supports a roll 21 of material which is to be cut into appropriate lengths for producing cards after the web 22 has passed ,through'the printing press and through the coating means 23.

The coating device, in the present embodiment of the invention, comprises a box-hke structure rectangular in plan, whose end wall 27 is rotatably supported at one side of the 24 terminates above the bottom 25 to produce a slot or opening 26, through whlch the web is drawn, as will presently appear. A roller device slightly above the bottom in order that the printed web may be drawn through the coating means close to the bottom thereof and under the coating material. The web is then guided through a slot 29 in a guide 30 to the drawing rolls 31 and 32 between .which the web travels and from which the web is projected over the stationary knife 33. In order that excess deposits may be removed from the web, a tapper orknocker. 34 is oscillatable in the path of travel of the web and it strikes the web intermittently to jar or vibrate it so that excess deposits are removed and descend. into the receptacle through which the web has traveled.

' .The tapper, in the present embodiment of the invention, has a rounded inner end which strikes the web and a tail piece 35 which extends outwardly into the path of rotation of the shoulders 36 of the shaft 37. L

The roll 31 has peripheral flanges at its ends in order that the flanges will engage the cards at the edges and straddle the printed surfaces of the cards, whereas the periphery of the roll 32 is plane and supports the card throughout its surface.

The rolls 31 and 32, as well as the shaft 37, are geared together by a train 38 in order that they will operate in unison, the roll 32 being positively driven through the pinion 39 and gear wheel 40, which gear wheel 40 is secured on a shaft 41 journaled on a post 42 in any suitable manner. The gear wheel 40 is engaged by a dog 43 that is pivoted on an arm 44' carried by a sleeve 45 that is rotatable on a shaft 46, and the action of the dog is controlled by a segmental shield 47 having a hub 48 adjustable on the shaft on gage a tooth of the wheel 40 and impart rotary motion to the said wheel. If the shield 47 is positioned to release the dog to engage the wheel early in its movement, the degree of rotation of the wheel 40' will be greater than that when the'shield is set to prevent the dog from engaging the wheel 40 so early in its movement, and it is by this arrangement that the degree of movement imparted to the web at each operation of the drawing and cutting mechanism and the size '.of the card severed from the web is determined, as it will control the length of the feed of the drawing rolls. The hub 48 may be secured to the shaft at different positions of adjustment by any suitable means such as a set screw, as those skilled in the art will understand. 'L

As has been stated, the web is drawn in a step by step motion overthe knife 33 and a. movable knife 48 operates in conjunction with the stationary knife for cutting the cards. The knife is oscillatable on the shaft 46 in conjunctlon with a frame which is also oscillatable, and the said frame, in the present embodiment of the invention, consists of arms 49 and 50 which are conneeted'together by a rod 51, and the knife '48 1s-also connected to the said rod 51. The knife 48 and the arm 49 have projecting trunnions 52 constituting wrist pins on which pitmans or connecting rods 53 operate. The arm 49 has a hub 54 rotatable on the shaft 46 and the arm 50 has the sleeve or hub 45 on its end, the said sleeve 45 and its function having been described, and the knife is carried into an operative relation to the knife 3321s the frame oscillates.

A power shaft 56 is provided with a drive wheel 57 that may have power transmitted to it in any appropriate way, as by a belt, and the said shaft 56 has a pinion 57 secured to it which meshes with a gear wheel 58 on the shaft 59. The shafts 56 and 59 are ro- I located a suitable distance rearwardly of the printing mechanism and parts associated with it. The gear wheel 58 has a wrist pin 62 to which an end of a pitman 53 is connected, the wrist pin, of course, being eccentric to the shaft. The shaft 59 also has a wheel 63 on the end opposite the wheel '58 and it has a wrist pin 64 to which a pitman 53' is connected in order that power may be applied to both ends of the frame for imparting oscillatory motion to the said frame.

From the foregoing description and by reference to the drawing, it wi 1 be apparent that a web of material to be treated or printed is drawn from the roll 21 through the printing press or mechanism and threaded through the coatin means under the roller-27 and through t e slot of the guide 30, the relation of parts being such that the web will pass in such juxtaposition tothe tapper as to be intermittently struck by the tapper as the tapper oscillates, it being understood that the tapper is oscillated by reason of its tail piece being struck by the shoulders 36 as the web is being drawn. The web is inter osed between the feed rolls 31 and 32, w lich latter is mounted on the shaft 41 in order thatit may be positively driven. The shafts of the rolls 31 and 32 and the tapper are geared together so that they operate positive in unison, and as power is imparted to t e drive shaft 56, the frame, through the, connections described, will be oscillated and as the frame is oscillated, the dog 43 will impart motion to the web to project a finished card beyond the knives, it being understood that the card will have reached the limit of its outward movement at the time the movable. knife is approaching the stationary knife, this timing of the feed and the movement of the cutting mechanism being one that will be understood by those skilled in the art.

After the card is severed from the 'web in its coated state, it is subjected to a bak ing process through the em 10 mentof a conveyer and an oven, w ic conveyer should be located in such relation to ,the cuttin device as to receive cards which drop rom the web as they are severed.

The conveyer and baking device or oven of the present invention includes any suitable frame 63 having drums 64 and 65 journaled at its ends, over which a wire mesh conveyer belt 66 is operated. It has been found in practice that owing to the character of the wire mesh, the belt does not run straight at all times, but has a tendency cased, but which preferably has a structure comprising a lurality of side posts 69 and upper and ower transversely disposed plates 70 and 71, respectively, that constitute supports or anchorages for the top and bottom walls 72 and 7 3, respectively. The top and bottom walls may be of any heat resisting or refractory. material such as asbestos and they constitute bases on which the heating elements are installed.

belt 0 erates' through an oven which may be suita 1y en- It has been found in practice that the degree of heat effective to produce the best results in fusing, melting or' otherwise'treating the deposits used in embossed printingis a t to scorch the card when subjected to the mat for the desired length of time to produce the best results, and therefore, the

applicant has providedan oven having zones o and 73 constitute bases on which appropriate fittings orlterminal plates 74 may be secured the same being arranged as separate units on each side of the bases and having suitable terminals to which resistance elements 7 5,-in the nature of vire, may be connected in a manner to permit current to be supplied to the group of resistance elements at one end of'the furnace, or to the group at the other and of the furnace, or to the groups simultaneously. Furthermore, each resistance element is a unit of comparatively short length extending from one plate to-the other, and if any one of the short lengths becomes'impaired, it can be renewed without excessive cost.

The wiring diagram is shown in Fig. 6 and a description of the same is believed to be unnecessary to an understanding of the arrangement, it being sufficient to say that suitable switches 76are provided for controlling the circuits.

As the upper and lower walls of the furnace carry heating units, the cards will be subjected to heat from above and beneath and such heating also adds to the efficiency of an oven intended to treat deposits for embossed printing. but in order to maintain the conveyer in such relation to the heating devices as will cause a uniform action on the cards, the conveyer is guided within the furnace on cross-bars 77- which are somewhat similar to the cross plates 70 and 71, except that the cross bars have convex upper surfaces to minimize the friction between the conveyer belt and the said bars. Preferably the space between the conveyer and the upper heating elements is slightly greater than the distance between the conveyer and the lower heating elements, as this will allow for any distortion of the card or material as it is being carried by the conveyer. When cards and the like are heated, they have a tendency to .curl or bend, so that by the relation of parts just indicated, a greater clearance will be above the conveyer in order that even if they become distorted, they will not come in contact with the heating elements. The presence of the lower heating element minimizes the curlin action or distortionof the cards in order t at'if the heat is properly regulated, there is little danger of undue misshaping of the cards.

Power may be applied for operating the drums in any convenient manner, but as here shown, a. shaft 78 has ,a pulley 79 secured on it, which may be engaged b a belt or other driving means, the said s aft '78 having a pinion 80 engaging a gear wheel 81 on a stub shaft 82. The gear wheel. 81 is connected to a pinion 83 on the stub shaft for the purpose of driving the same, and the pinion .83 meshes with a gear wheel 84 on the shaft 85 of the drum '65. Of course, other means may be provided for operating the conveyer, and the inventor does not wish to be limited with respect to the same.

It is the purpose of the inventor to have the arrangement such that his switches will deliver current to the heating agents in a manner to produce heat at the upper and lower zones of the furnace at high and low temperatures or when the heat is increased or diminished and, of course, in the event that other heating a encies are employed, he would provide for heating both the upper and lower zones at about or approximately the same temperature in order that the heat through which the web is moved for r'eceiv-' prlate engths from the web.
