1 Claim.

This invention relates to ruling machines for paper or the like and more particularly to the method of supporting and adjusting the pens of such machines.

An importantobject of the present invention is the provision of a ruling machine provided with an adjusting mechanism which may be readily operated to adjust the spacing of the pens.

- A further object of my invention is to provide a device of this character whichwill always maintain the even spacing and parallel arrangement of the pens.

Still another object of my invention is the provison of a device of this character which is of simple and'inexpensive construction,which maybe Other objects and advantages of my invention will be apparent during the course of the following description.

In the accompanying drawing which forms a part of this specification and wherein like characters of reference denote like parts throughout,

Figure 1 is a side elevation of a portion of a ruling machine embodying my invention,

Figure 2 is a top plan view thereof,

Figure 3 is a transverse sectional view through the machine on the line 3-3 of Figure 2,

Figure 4 is a similar View on the line 4-4 of Figure 2,

Figure 5 is a longitudinal sectional view on the line 5-5 of Figure 2,

Figure 6 is an enlarged fragmentary sectional view through one end of the adjusting mechanism, and,

Figure '7 is a longitudinal section taken on line I'l of Figure 2.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral Ii! designates the side rails of the frame of the machine between which the flexible belt II of fabric or the like moves to convey the sheets of paper past the pens. Upright standards I2 are bolted to the top of each rail III at diametrically opposite points to support the pen carrying mechanism. One side of each standard is provided with a fiat leaf spring I3 bolted to the standard at a point spaced a substantial distance below the top thereof, the springs I3 extending a substantial distance above the tops of the standards. Elongated bearing members or blocks I4 are spaced a slight distance above the standards I2 and secured at their ends by bolting or the like to the flat leaf springs 53. The bearing blocks I4 extend longitudinally of the rails It above the tops of standards I2 and spaced therefrom, being normally held in a sub stantially horizontal position by the tension of springs I3 but being capable of movement against 5 the tension of the springs I3.

A pair of guide shafts I5 are received in horizontal transverse bores arranged adjacent the ends of thebearing blocks M and are secured against rotation in the blocks I4 by means of 10 set screws I 5 or the like. The shafts are of substantial thickness having a smooth, preferably polished, surface and are arranged in normal horizontal alignment being supported by bloclcs'l l and movable therewith. Rectangular 15 pen supporting plates ii are provided with spaced openings to slidably receive the guide shafts I5. Pens it of any suitable construction are bolted to the top edges of plates I! and extend diagonally down to the belt II, being held in proximity to the belt and the paper thereon by tension of springs I3. The plates H are provided with aligned central openings l9 and a screw shaft 28 is journaled in one of the blocks I4 extending freely through the aligned openings I9, and through the other block I4. The screw shaft 28 terminates in an operating crank 2I and is held in position between the blocks I4 by means of a collar 22 secured to the shaft and abutting against the inner edge of the block I4 as seen I in Figures 2 and 3. The openings I9 are of greater diameter than screw shaft 20 and permit free rotation of the shaft. The end plate I'I, adjacent collar 22, abuts against collars 23 secured to the guide shafts l5 at points spaced from the block I4 while the opposite end plate abuts against, or may be secured to, a cross-head plate 24 slidably engaging the guide shafts I5 and having a screw-threaded engagement with screw shaft 20. The pen holding plates I! are maintained in even spaced relation by means of coil springs 25 of identical length and tension which surround shafts I5 between adjacent plates H.

The spacing springs 25 will maintain an even spacing of the plates I1 and due to the spaced relation of guide shafts I5 which have a bearing contact with the openings in the plates I1 and the action of the springs 25 at opposite ends of pen holder plates H, the plates I! will be held in their parallel longitudinal position relative to the machine.

. When it is desired to adjust the spacing of the pens I8, crank 2I is operated to rotate screw shaft 20 and move cross-head 24. The movement of the cross-head adjusts the position of the adjacent plate l1 and as the opposite end plate I! is held stationary by collars 23, the springs 25 will be compressed or expanded to move the intermediate plates II to provide a new even spacing of the plates and pens. By rotating crank 2| in the desired direction, the pens l8 may be moved farther apart or closer together under action of springs 25, always maintaining their even spacing and parallel relation. With this construction, only one set of pens is required for ruling lines of any desired spacing, and the desired adjustment may be easily and rapidly obtained. I

In order to move the pens l8 out of contact with the paper to provide heading space or whenever it is desired to stop the ruling of the paper, I provide a lift finger 2B whichmay be clamped to the guide shaft I farthest from leaf spring I 3 as shown in Figures 2 and 7, or secured in any other fashionto one of the blocks l4 or their connecting shafts. The finger 26 extends downwardly to a point adjacent the rail l0 and terminates in a normally horizontal extension through which an adjusting bolt 21 extends, A lock nut 28 engages the bolt 21to maintain its adjusted position. A push rod 29 is slidable vertically in a sleeve 30 carried by the rail of the machine and is arranged in vertical alignment with and directly below the adjusting bolt'21. The lower end of rod 29 extends below the sleeve 30 and carries a roller 3| which isadapted to engage the periphery of a rotating cam wheelr32 having a cam or cams 33 to engage the roller 3! and raise the push rod 29. The cam 33 is preferably removable so that cams of different sizes maybe employed. The cam wheel 32 is rotated during cated in Figure 7. While the pens are in their raised position, no lines are ruled on thepaper,

and as the roller leaves the cam 33 the pens are lowered into contact with the paper by springs l3. While I have shown and described the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claim. I

Having thus described my invention, what I claim and desire to protect by Letters Patent is: In a ruling machine, a pair'of end members supported by the machine, a pair of spaced par- .allel guide shafts carried by the end members,

a series of pen holders slidably supported on said guideshafts in spaced relation, a series of coil springs carried by each guide shaft and arranged between the pen holders to space the holders,-said springs being of equal length and'tension, stop members arranged adjacent one end of the shafts, adjusting means arranged between the guide shafts and engaging one of the pen holders to adjust the spacing of the pen holders, said adjusting means comprising a screw shaft rotatably supported by the end members and extending freely through openings in the pen ho1ders,'and means operatively connecting the screw shaft with the holder at the end of the series opposite to the stop members on the guide shafts.

LOUIS S; FORSYTHE.
