To (ZZZ whom it may concern:

Be it known that I, SAMUEL LIiesIUs, a

citizen of the United States, and residing at 105 John street, New York,"in the county of New York and State of New York, have This invention deals with a unitary self-'- contained" apparatus in the nature of an embossographer', adapted automatically to produce ,so-called raised, 'printing""' in simu lation of engraving. I

The primary object of this invention is to create and render commercially available an apparatus'which will enable printers to produce imitation embossed Work so rapidly cheaply and easily as to enable large quantities of material to be turned out at a cost only slightly exceeding that of ordinary printing.

-' Heretofore, raised printing in imitation of embossed or engraved work has been acmany disturbing influences and are quite incapable of effecting si'lbstantial economies in handling large orders, because of the fact that the expense cannot be materially reduced in proportion to the volume of work features of construction, combinations of to be turned out. This invention, however,

by'reason of its automatic character and.

its nicety of control, enables the output to be greatly speeded up whenhandling a large order of the same printedmatter, and consequently this invention further improves and the annexed drawings and in part indicated in connection therewith by-the following analysis of this invention.

This invention accordingly consists in the parts, and in the unique relations of the erence denote corresponding shown in sectional elevation.

and disposition thereof; all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention,

drawings depicting a preferred form have V been annexed as a part of this disclosure, and in such drawings, like characters ofrefparts throughout all the views of which Figure 1 is a side view of my combined printer, powderer, excess-remover, conveyer and fuser', parts; being broken away and i Fig. 2 is a vertical sectional elevation, drawn on an enlarged scale, of the powder-er for containing and distributing an excess of the powder on theprinted portions of'a sheet. Fig.3 is across-sectional view taken on the line 33 of Fig. 2. Fig. dis a perspective view illustrating one of the minor details of construction. Fig. 5 is aperspective view'of one form of sheet-feeder. Fig.6 is a' side view illustrating certain details of construetionthereof. Y I v In the accompanying drawings, I have shown how a printing press of the Gordon variety may be embodied as one of the elements of my combination; enough onlyof the press and the other elemental mechanisms being shown to illustrate a fair example of a complete practical application of the invention. In these drawings, 10 indicates the frame of the press; 12 is the main driving-shaft: 13 is the prank-Wheel to which the pitman 15 is connected by means of a wrist pin 14. This pitman 15 engages the shaft 16 which is adapted to actuate the swinging-frame 17, and it extends trans.

versely between the arms of the oscillating frame 22, which supports the type. The

frame 17 ,is provided with an. offshoot 18 having a wrist-pin 19, to which is connected alink 20. This link is pivoted to the frame 10,by means of the wrist-pin 21, and is I 23, having anaperture 24 for reeeiving bolts 25,, which are employed as a means for ad- .justably connecting the resilient arms 26 to the swinging frame; these arms, are respectively provided with a slot 27,'Whereby they may be adjusted to suit requirements.

Of the printed-sheet outwardly and away from it and its supporting quads 32,-and

Each arm 26 is provided at its free end with a gripper A, comprising a resilient aw I '28 (see Fig. 5) having a stud 29, which passes through an opening through the end of the resilient arm 26, wherebysaid aw is normally-closed againstthe free end of said resilient arm. Pivotally attached to the arm 26, by means of a pin 31, is a tapered gunle or pawl 30, adapted for lifting the lower end guidingit between the-jaws of the gripper A. The platen 11 is provided with recesses 33 for accommodating thefgrippers A, the surface of said recesses contacting with the studs 29,,iasthe grippers enter for the purpose of' opening the jaws. 28, whereby the printed'sheet may readily enterthe grippers and be carried away thereby, as will be here-- inafter described:

. As a means for holding and distributing the powder, -I employ a receptacle B, em.

- ,bodying the upper compartment 35 and the lower compartment 39, the former having outlet openings in its bottom which are normally closed by the sliding door 36. This.

door is maintained in closed position by means of suitable springs 37. The sliding door 36-:moves on guides 38, and it is provided with depending pins 36 for engagement with trips 34 projecting from the resilient arms 26. These trips open the sliding door during therearward stroke of the arms 26, by means of their shoulders 1; their tapered edgeparts 2 riding over said pins 36 on the forward stroke.

The compartment 39 is hopper-shaped and its outletleads .into a tube 41, which dis-- charges into the upper compartment 35. Said tube, immediately below the outlet of the hopper 39, is provided with an injector nozzle 40 which leads from a suitable source printed sheets to shake the superfluouspowder therefrom.

Passing longitudinally between the upper and

lower compartments

35 and 39, areendless belts composed of flexible fabric, such as coarse wire-mesh, so that they need not lmpede'the powder from droppinginto the lower compartment 39. The belts 45 pass around rollers 46 and 47,.and the conveying movement is imparted thereto by meansof a suitable source of power, such as a pulley 48 driven by means of a belt 49 which is, in

turn, driven from the main-driving shaft 12.

The roller .46 is journaled between suitable 76 uprights 50 mounted in fixed relation to the main frame; and the roller 47 is journaled to the. main' frame 10. 'An offset constituting a trip 50 extends 'from a suitable support 52 and is adaptedto engage ,the' studs 29 ,ofthe grippers A to open the'jaws-28, at the end of the stroke of the swinging frame 17 whereby the sheet isreleased an allowed to drop on to the-belts'45. I

As a meansfor heating the sheets to fuse the fusible powder into the ink, an elongated bOX CI 1s em loyed This box'is'heated to the require degree by any suitable heating agent, and it has wire-mesh endlessbelts I. 53 extended longitudinally "'therethrough for slowly carrying the sheets through the fusion zone of thebox. The sheets, as theyare discharged from the belts 45, are fed on to the tilted table 54 and slide therefrom through an opening-55 into the heating receptacle C; within which they-are received by' thebelts53 and carried through the compartment. Movement is transmitted to the belts 53by means of pulleys 57, 58 and a belt 59. I have only shown one end of the heating receptacle,.as' I believethat to suflice for lllustrative purposes.

-During the operation of this invention," the compartment 35 will be charged with a,

suitable fusible powder and, as soon as a sheet 1s printed in a conventional manner, it

' is intermittentlygrasped at its lower edge by the grippers and carried beneath the compartment 35 of the powderer. Meanwhile, the powderer automatically sprinkles powder on thesheet; this being done by the rear:

ward movement of the, resilient arms 26 which open the sliding door 36 by means of their trips 34. The sheet thus receives an abundantor excess coating of fusible pow- 'der on its printed surface. As soon as the sheet has been coated (and preferably just before itis released from the grippers), the rotating shaft 43 comes into on the paper, whereby its paddles 44 strike and agitate the,.sheet, thereby causing its superfluous powder to slide ofl' the non-tacky unprinted portions of the sheet and discharge into the lower compartment 39. The I 5 trip 51 then opens the jaws 28 of the grippers. and allows the sheet to drop on to the belts 45, from whence it is automatically fed to the heating and fusion chamber. During its passage therethrough, the fusible powder wh chadheres to the tacky ink now melts effective action and amalgamates with the ink, thereby pro- 'ducing raised printed matter.

The door 36- may be so timed in its movements as to either coat-the entire sheet or only parts thereof when it is desirable to produce printed matterwhaving' parts 30m,-

posed of raised letters andi kparts: fiatembodying ordinary printing. All partsof the operation and improved'amethodiof production, however, require zthe employment of purely automatic mechanical means only,

, wherebythe process is-hastened, the'cost of production is {*lOWGIGCl, and. operatives "around thepress are shielded from the deleterious effects of the, powde1' andthe fumes engendered thereby;

*Without further analysis, the foregoing will so fully reveal the gist of-this invention that others can by applying current knowlconstitute essential characteristics of the "'genericor specific aspects'of this invention,

and therefore such adaptationsshould and are intendedto be comprehendedwithin the meaning and range of equivalency of the following claims.
