To all whom t may concern.'

Be it known that l, VERNON ROYLE, a citizen of the United States, and resident of Pat erson, in the county of Passaic and Stateof New Jersey, have invented a new and useful l-landliiner for Photo-Engraved Plates, of which the following is a specification.

My invention relates to a hand liner for photo-engraved plates, the object being to provide a simple, durable and effective hand arrangement for forming a line at the desired distance fromthe edge of the plate within the limits of the apparatus.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a top plan view showing the parts in the position which they assume at or just before the beginning of a cut, Fig. 2 is a partial transverse vertical section in the plane of the line A-A of Fig. 1, Fig. 3 is a view of the same in end elevation, Fig. 4 is a view of the same in front elevation broken away through the center, Fig. 5 is a view in a longitudinal vertical section broken away through the center and looking toward the front, Fig. is a view in detail showing in elevation partly in section the gage supporting bar, and Fig. 7 is a view in detail of the stock for holding the plate against movement in one direction during the cutting operation.

The base of the apparatus comprises a table 1 recessed at its end toward the operator to form a tool tray 2, the table being conveniently supported upon three legs denoted, respectively, by 3, 4 and 5, by means of which the base may be fastened to the top of a table or other suitable support.

The several parts of the base, including the legs, may be conveniently cast in one piece, the extension of the body portion which forms the vplate supporting table 1 to form the tool tray 2 being resorted to for the purpose of utilizing a space which would otherwise be blank since the structure requires the extension of the base along its front a distance past the plate sup orting table proper to afford a rearwardly siding movement of the tool-carrying sleeve into a position to begin a line at or near the end or side of the plate as the case may be.

At the front the base is supplied with a pair of brackets 6 and 7 terminating in bearings 8 and 9 respectively for the reception of the ends of a guide, in the present instance a rock shaft 10 which extends along the front edge of the base. The bearing 8 is split and its two parts are forced together by means of a screw 11 operated by a lever 12 for the purpose of clamping the shaft 10 in such rotary i adjustment as may be desired. The said shaft 1() is provided'at its end farthest from the operator with a screw thread 13 on which a nut 14 isv placed for the purpose of determining the point at which the tool shall stop :i

its advance movement as will hereinafter appear. The shaft 1() is provided on its opposite ends with pins 15 and 16 set in alinement and eccentric to its axis, the-said pins being connected by links 17, 18, with the opposite ends of a gage supporting bar 19. The gage supporting bar 19, has its ends 20 and 21 reduced and screw threaded to pass through the links 17 and 18 and the said bar 19 is firmly held between the links by nuts 22, 23, screwed onto the said screw threaded ends of the bar snugly against the outer faces of the links 17 and 18.

The bar 19 is flattened throughout a p0rtion of its length corresponding to the length of the plate to be lined, as shown at 24 (see Fig. 6) and this attened portion receives the outer edge of the gage 25, the latter resting flatly on the flattened surface 24 and having a swinging adjustment in a horizontal plane on the said flattened surface 24 of the bar 19 as follows :-The screw 26 which passes through the gage 25 into the bar serves, when slightly loosened, as a pivot on which the gage may be rocked in a horizontal plane by means of a screw 27 having its head lset eccentrically with the head of its stem and called, for short, an eccentric headed screw, the head of said screw working in a longitudinally elongated slot 28 in the gage plate. Screws 29, 30, at intervals apart pass through transversely elongated openings 31, 32, in the plate to permit the latter a slight swinging movement in a horizontal plane under the impulse of the eccentric headed screw 27. This horizontally swinging adjustment of the gage 25 serves to adjust its edge toward the plate in exact alinement with the path of the'cutting tool so that the plate, when resting against its edge will have the line Icut by the tool located at exactly the same distance from the edge throughout its length.

On the rock shaft 10 there isv located a sleeve 33, the length of which is intended to be sufficient to afford a convenient seat for the operators hand, the said sleeve being conveniently provided with an annular bead 34 near its rear end to keep the hand from slipping back from the sleeve and a horn 35 near its forward end to form an abutment t0 keep the hand from slipping in forcing the tool forward to do its cutting work. The horn 35 also serves to assist in rocking the sleeve 3 on the shaft 10 for purposes which will hereinafter appear.

The sleeve 33 carries the operating'tool and for this purpose it is provided with a transverse socket-piece 36. The said socketpiece has a reduced cylindrical portion 37 at its end toward the plate-supporting table. A through bolt 38 extends longitudinally through the socket piece 36 and its reduced portion 37 and is provided at its outer end with a screw thread for the reception of a tail nut 39.

Between the head of the bolt 38 and the end of the reduced portion 37 there is located a disk 40 which is drawn tightly toward the end of the reduced portion 37 by the nut 39 on the end of the bolt and serves to clamp, between it and the end of the part 37 a cutting tool 4l. The disk 40 is prevented from displacement in a rotary direction by means of a projection 42 on its face which enters asocket 43 in the end of the part 37. The disk 40 also has an arm 44 (see Fig. 5) projecting toward the operator from the disk and forming a support for a forwardly depending link 45 which supports the rear end of a shoe 46 through which the cutter 41 projects, the said shoe 46 being intended to bear on the plate and determine the depth of cut by the relation between the plane 'of its lower face andthe plane of the point of the cutter. The forward end of the shoe 46 is supported by an arm 47 projecting obliquely downward from a sleeve 48 mounted with a close rocking fit on the reduced part 37 of the socket piece, the line between the axis about which the sleeve 48 rocks and the center of the connection of the arm 47 with the forward end of the shoe 46 being parallel and of equal length with the link 45 measured from center to center so that any raising or lowering of the forward end of the shoe 46 by the arm 47 will cause the entire shoe 46 to be bodily raised or lowered with its lower or bearing face parallel to the surface of the plate. The adjusting of the sleeve 48 in a rotary direction'on its bearing is accomplished by means of an adjusting screw 49 which extends downwardly through a tail piece 50 projecting toward the operator from the sleeve 487 the said screw having a screw threaded engagement with the said tail piece and bearing at its lower end on a lug 51 fixed with relation to and preferably integral with the socket piece 36. To the under side of the lug 5l there is secured the end of a bar spring 52, the said spring projecting forwardly and its free end forming a support for a forwardly projecting arm 53 fixed with relation to and preferably integral with the aforesaid sleeve 48. -The said arm 53 is conveniently providedwith a laterally projecting pin 54 which bears on the s ring 52.

From this structure it flbllows that when 'the adjustingscrew 49 is turned downwardly it will lift the tail piece 50 'and rock the sleeve 48 in a direction that will depress the free end of the spring 52 and at the same time will swing the links which support the bearing shoe 46 into a direction nearer the vertical and so will lower the shoe with respect to the cutting edge of the cutter and thereby lessen the depth of cut. On the other hand, when the screw 49 is turned in a direction to raise it, the bar spring 52 will rock the sleeve 48 in the opposite direction tending thereby to lift the bearing shoe 46 with respect to the cutting edge ofthe cutter and thereby increase the depth of cut.

The sleeve 48 is further provided with a thumb piece 55 projecting toward the op# erator and so located -with respect to the hand of the o erator when the latter is grasping the hand e or sleeve 33 that the operator may press his thumb on the piece 55 and so force the cutter down to its work as it is pushed along by means of the sleeve or handle 33.

By rocking the handle 33 on its support 10, the cutter may be caused to gradually enter to its full depth of cut at the beginning of the line and by rocking the sleeve in the opposite direction may be caused to gradually recede from its full depth of cut at the end of the line thereby carrying the line at its end out to a very fine finish and this is accomplished without any hindrance to the continuous advance movement of the cutter.

The plate to be operated upon is adjusted on the table l by means of the gage 25 so far as the direction of the line of cut is concerned as has hereinbefore been particularly pointed out and it is prevented from slipping in the direction in which the cutter is advanced by means of a stop pin 56 which is seated in a shouldered socket 57 in the table as clearly shown in Fig. 7 and is permitted a 'freedom of rotary movement which will permit the pin to automatically adjust itself with its V-shaped opening 58 directed toward embracing the edge of the plate by the pressure of the edge of the plate against the walls of the said opening.

In addition to the stop 56 I find it convenient to provide the plate supporting table 1 with a laterally swinging stop 59 pivotally secured to the table at 60 and its free end provided with a slot 61 through which a set screw 62 extends, the latter being tapped into the table to lock the stop 59 in the desired position to correspond to the direction of the advance edge of the plate. When the a paratus is used in connection with large p ates the stop 59 is found convenient but when used in connection with small plates the self adjusting stop 56 is found to be practical and entirely satisfactory.

The apparatus as a Whole 1s so arranged as i to enable the operator to expend his strength in a very advantageous manner in forcing the cutter along the plate and the adjustment of the depth of cut may be made withgreat facility to give the desired prominence to the line while, at the same time, the adjusting of the gage by its eccentric ins provides for a universal adjustment to t ie finest degree of accuracy at all points within the limits of the range of the eccentric so that'one or more lines may be formed along the edge of the plate at any distance within the range of the apparatus that may be desired.
