WiACl-HNE FOR WHTERING PRINTERS RULES.

SPECIFICATION forming part of Letters Patent No. 718,837, dated January 20, 1903.

Application. filed December '7, 1901. Serial No. 85.017. (No model.)

To aZZ whom it may concern:

Be it known that I, HANS C. HANSEN, a citizen of the United States, residing at Newton, in the countyof Middlesex and State of Massachusetts, have invented an Improvement in Machines for Mitering Printers Rules, of which the following description, in connection with the accompanying drawings, is a specification,like characters on the drawings representing like parts.

This invention has for its object the production of a novel and simple machine for mitering printers rules.

In my invention the rule-holder is shaped externally to conform with a right-angled triangle or to present a corner of ninety degrees at that end thereof occupying a position in the plane of movement of the knife, and with a r'uleholder having its sides arranged to represent a right-angled triangle I may use one face of the rule-holder after the other to sustain the rule to be mitered at its ends, and without adjustment of the ruleholder on the segment I may place the rule against the opposite face of the rule-holder and miter the opposite end of the rule, so that both ends of the rule may be mitered to any desired angle without changing the position of the rule-holder. I have also provided one edge of the'rule-holder with a scale indicating picas, and said edge sustains an adjustable gage against which the outer end of the rule to be mitered is held while the knife is being actuated to out the final miter. The gage is made adjustable on the rule-holder, and I have provided the rule-holder with a gage-controller, and by a change of position of said controller the acting end of the gage may be adjusted to a determined nicety to thereby insure exactly the proper length of rule, as it will be understood that any diiference in length of the rules used to make up any form will result in imperfect printing.

Figure 1, in elevation, shows a machine of the class described embodying my improvements. Fig. 2 is a plan View thereof. Fig. 3 is a section in the line :15, Fig. 2. Fig. 4: is a section in the line 50, Figs. 1 and 2. Fig.

5, on an enlarged scale, shows part of one edge of the rule-holder with the gage and controller in position. Fig. 6 isa detail showing the stand 13 and the lug sustaining it, and

Fig. 7 shows a rear side view of the controller.

The framework consists, essentially, of a base A, having uprights A, provided with a suitable log or lugs A The inner edges of the uprights are grooved at a to receive side lugs ct, extended from a knife-carrier A (shown as provided with lugs 11. c that receive between them the convexed edges 2 2 of a handle 13, mounted on a stud B, fixed in a stand B having its shank fitted loosely in a hole in an ear A of the frame and held in said hole against vertical movement by a suitable nut 3, said stand being free to be turned in said car as the knife-carrier to be moved by said lever is making its several cuts. The handle B is offset at 5 to place it far enough from the rule-holder 0, when the arm 0 thereof is parallel with the edge of the knife, to thereby enable the hand of the operator to clear the rule-holder. The lug A receives a bolt D, that holds the segment D in position on the frame.

The parts so far described, with the exception of the shape of the handle B, are common to other machines of this nature.

The segment I) has a groove 6 cut in the arc of a circle, and said groove is entered by two like studs 7, one being shown by dotted lines, Fig. 2, extended from the bottom of the rule-holder, said studs in said groove insuring the movement of the rule-holder when being adjusted in a circular path. The segment D is slotted at 9, and the rule-holder C has a screw-threaded opening (see Fig. 3) to receive the threaded shank of a thumbscrew 10, passed through slot 9, by which to clamp said rule-holder in any position in which it may be adjusted according to the angle or direction of the miter to be out. The knife-holder has two slots 12, through which are passed two screws 13, that enter threaded openings in the knife B said screws clamping the knife in any position of adjustment thereof which may be made through the action of the screws 14. acting against the shanks of the screws 13. (See Fig. 4.) The rule-holder has its rule-sustaining faces arranged to represent a right-angled triangle,

or the rule-sustaining faces meet next the path of the knife and present a corner of substantially ninety degrees.

The rule to be mitered may be laid against one and then against the other face of the rule-holder while the knife is actuated in usual manner to cut the rule at its ends. In mitering the first end of the rule I may lay the flat side of the rule against the face a of the rule-holder, and, having mitered one end, I take the rule, turn it end for end, and lay the same side against the other face 0 of the rule-holder with its mitered end against the gage e, which may be held in its adjusted position by a suitable set-screw 15, the inner end of said gage being adjusted properly with relation to a pica scale formed on the face 0 of the rule-holder, as shown at the left in Fig. 2.

Sometimes the acting end of the gage e, to provide for a definite length of rule to be mitered, must be adjusted to occupy a position between the finest or shortest marks of the pica scale, and consequently I have provided the face 0 of the rule-holder with a series of holes 16, in any one of which I may enter the eccentrically-located shank 17 of a controller h. The pica scale on the edge of the side 0 of the rule-holder is divided by lines separated about one-sixth of an inch apart; but in setting type thejustification frequently requires that a rule be cut of a certain numher of picas in length and fractions thereof. I have provided the controller h, Which may be used expeditiously and to great advantage in defining the exact positions of the gage to provide for the manufacture of rules representing in their length picas and fractional portions thereof. The controller h is shown as ablock having its ends and sides of different lengths, and by turning said controller, the eccentrically-located shank 17 entering one of the holes 16, it is possible to adjust the gage accurately for fractional pica lengths. In the construction embodying my invention as I have herein chosen to illustrate it the 4 controller is provided with certain marks or numbers, and when the position of the controller is changed so as to bring the mark or number 1 on the controller uppermost it is possible to insure the placing of the acting end of the gage e on a line of the pica scale indicating an uneven number of picas, and when the number 2 is uppermost the end of said gage is positioned on aline indicating an even number of picas. When number 11 2' is uppermost, the end of the gage e is positioned to indicate an uneven number of picas and a fraction of a pica, and when the number 7% is uppermost the endof said gage is put in a position to indicate an even number of picas and a fraction thereof. By the use of this controller accurate measurements as to the length of the rules may be secured.

I have provided the segment 01 with a series of holes 18, which form part of a scale, and said holes are entered by a suitable pin 19, carried by the rule-holder, so that by changing the pin and making it enter one or the other of said holes the exact miter, angle, or bevel desired for the end of the rule may be determined absolutely-as, for instance, the adjustment of said pin in one or the other of said holes enables me to miter on the machine accurate angles for the production from said rules of a triangle, a square, or any quadrilateral, a pentagon, a hexagon, a heptagon, an octagon, or, in fact, any desired angle.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for mitering printers rules, a circularly-movable rule-holder having its edges arranged at right angles to each other, one of said edges carrying a pica index, a gage adjustable at the edge of said rule-holder, and a controllerindependent of the gage and sustained by the edge of the rule-holder and adapted by its change of position to change the position of the acting end of said gage.

2. In a machine for mitering printers rules, a circularly-movable rule-holder having at one of its edges a pica index, a gage adjustable at the edge of said rule-holder, and a controller independent of the gage and sustained wholly by the edge of the rule-holder and adapted by its change of position to change the position of the acting end of said gage.

3. In a machine for mitering the ends of printers rules, a rule-holder presenting a corner of ninety degrees and having one of its side edges provided With a series of holes, a gage adjustable on the edge of said ruleholder, a controller composed of a block having an eccentric stud, projecting from one face thereof and entering the holes in one edge of said rule-holder, the rotation of the controller bringing one or another face thereof in contact with the rear end of said gage and adjusting the same on the edge of the rule-holder.

4. In a machine for mitering printers rules, a knife-carrier having a slotted flange at the upper end, a knife, two clamping-screws extending through the slotted flange of the knife-carrier and entering threaded holes in said knife, and two adjusting-screws acting by their ends against said clamping-screws to adjust the cutting edge of the knife in operative position, said clamping-screws being thereafter turned to clamp and hold the knife in adjusted pdsition.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HANS O. HANSEN.
