PARALLEL LINER.

Specification of Letters Patent.

Patented July 8, 1913.

Application filed September 12, 1910. Serial No. 581,515.

To all whom it may concern Be it known that I, LINN Born BENTON, a citizen of the United States, residing at llaintield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Parallel Liners, of which the following is a specification, reference being had to the accon'ipanying drawing, forming a part thereof.

This invention relates to instruments for cutting, drawing or n'iarking parallel lines at various predetermined intervals apart. I ts main object is to facilitate performing such work with accuracy and generally to improve the construction and operation of instruments of this class.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

.ln the accompanying drawing like characters designate the same parts in the several figures.

Figure l is a plan view of a device embodying the invention; Fig. 2 is a vertical cross section thereof on the line 2 2, Fig. 1; Fig. 3 a plan view, similar to Fig. 1, showing the device without the cover plates, index or spacing wheel and operating lever; Fig. l: is an enlarged cross section on the line et at, Fig. 1; Fig. 5 is a like section on the line 5 5, Fig. 1; Fig. 6 is an enlarged detail view, partly in section, of the device for adjusting the liner laterally with relation to the work or pattern support and Fig. 7 is an enlarged sectional detail.

For the purpose of illustration a lining device specially designed for use with engraving machines for cutting matrices for shaded letters or characters is herein shown and tlOSCl'lbOtl, but with little or no change the device may be used :for other purposes within the principle and scope of the invention.

Referring to the drawing and more particularly to Figs. 1, 2 and $3, a designates a horizontal pattern or work support, in the present case the bed of a matrix engraving machine on which the pattern to be traced is held. it is provided on the rear side with ears or lugs 7) in which cone pointed screws 0' are threaded in line with each other. A rod (2 is rotatably mounted at the ends on the points of these screws parallel with the adjacent side and upper face of the bed a, and

on this red is mounted by means of lugs or cars c as indicated by dotted lines in Fig. 3, a plate or block f, which forms a support for the lining mechanism. The rod (Z passing through the ears or lugs c on the underside of the plate or block f, also passes through a tubular adjusting screw which is threaded as shown in Fig. 6, in a lug or car 71. on the under side of the plate or block f, and is provided with a head i which has a swivel connection with a grooved collar y fastened on said rod (Z by a set screw 70.

A longitudinally channeled guide Z has a transverse plate or oll'set m, which is pivotally connected with the upper side of the plate or block f by a screw or pin n. The guide l, which is thus capable of angular adjustment on the plate or block f, is fastened in adjusted position by a screw 0 passing loosely through a hole in the plate or ol'lset m and provided at its upper end with a clamping nut 71 and at its lower end with a head working in an undercut curved groove in the plate or block concentric with the pivot screw or pin a.

A bar 7' preferably of square or rectangular form in cross ltjlllOll, is tilted to slide in the channel of the guide Z and provided at or near one end with a laterally projecting ruling arm 8, preferably at right angles thereto, as shown.

In a recess formed in the upper part of the plate or offset m and intersecting at one side the channel in the guide Z, is rotatably mounted a drum If which is connected by belts u and '11 winding in opposite directions thereon with the bar 1' adjacent to its ends. The bar r is formed on the side next to the drum t with a longitudinal groove or channel to receive the belts u and c, which are stretched near their ends as shown in l igs. 1 and 7 over raised bearings on the bar to hold them out of contact with said bar and the opposing walls of the guide I between said bearings and the drum and thus prevent friction and wear. A single belt n, leads from the drum 6 toward the end of the bar '1', which is provided with the arm s, while two belts a, lead from said drum on opposite sides of the belt it toward the opposite end of said bar, where they are adjustably fastened thereto by a sliding block in fitted into a recess in the bar and tlu'eadml on an adjusting screw in arranged lengthwise of the bar, said block being formed with one of the raised bearings above mentioned. By means of this screw the head of which is accessible through the adjacent end of the guide Z, the belts 2) are stretched and kept taut so as to avoid any play or lost motion between the laterally movable ruling or guiding arm 3 and the rotary winding drum 2?, which operates it and determines its position. i g

The rotation of the drum t, the circumference of which is somewhat greater than the full traverse of the bar is limited to less than a complete revolution, so that each of the three belts u and amakes but a single wrap in winding thereon, and as they wind and unwind they are kept constantly in the same plane parallel with the guide Z, tangent to the periphery of the drum and at right angles to its axis. This arr angement for. converting rotary into reciprocating or rectilinear movement, avoids not only lost motion, but also any variation in the relative rate of speed of the drum and of the ruling arm, and it also avoids any strain which would cause excessive or unequal wear on the moving parts.

The channel in the guide Z in which the sliding bar 1" works, and the recess in the plate or offset m containing the drum t, are covered as shown in Figs. 1, 4t and 5, by removable plates y, 2 and 2. That part of the guide Z traversed by the endhof' the bar 1" to'which the arm 3 is attached by an offset shank 3, as shown in Figs. 3 and 5, is cut away on one side of the channel and the cap plate a is formed with a depending flange 4 extending downwardly over that side of the channel and of the bar. The spindle 5 of the drum 2?, which is journaled in the plate or ofiset m and the cap plate 2, is reduced and threaded at its upper end, on which are removably fitted interchangeable index or spacing wheels 6 and a nut 7 for fastening said wheels thereon. Index or spacing wheels, having different numbers of notches in their peripheries for cutting,

drawing or marking lines different distances apart, are furnished with each machine according to the nature and variety of the work to be done therewith. To prevent these wheels from turning on the spindle of the winding drum t, the shoulder or hub of the spindle'is provided as shown in Figs. 2 and 3, with a pin 8, which fits into a corresponding hole in each of said wheels.

A lever 9 is pivoted or fulcrumed on the spindle 5 below the spacing wheel 6 and next to the cap plate 2 and is provided with a pivoted dog 10 adapted when oscillated to engage with the notches in said wheel one after another, and to turn the wheel forward step by step predetermined intervals corresponding with the distance between the notches and the throw of the lever. The dog 10 is held in yielding engagement with the spacing wheel by a spring 11. To prevent overthrow of the spacing wheel and backward movement thereof with the Operating lever 9, a dog 12 is pivotally mounted on the cap plate 2 and is held by a spring 13 in yielding engage ment with said wheel. projection'l i which is adapted by engagement with the heel of the dog 12 to hold said dog in engagement with a notch in the spacing wheel and prevent overthrow of said wheel as the lever is brought to the limit of its advance movement. This projection with the dog 12 serves as a stop to limit the advance movement of the lever and of the spacing wheel. spring 15 connecting the lever9 with the plate 2, tends to turn said lever forward and hold the projection 14 in engagement with the dog 12, as shown in Fig. 1. stop 16 adjustably attached to the plate or offset m limits the backward movement of the lever 9 according to the spacing of the notches of the index or spacing wheel 6. The dogs 10 and 12 are provided with pins or projections 17 for throwing them by hand out of engagement with the index or spacing wheel 6, in order to move the arm 8 back to its initial or starting position toward the plate or offset m.

The lateral movement of the guiding or ruling arm s is limited by stop screws 18, threaded in the end plates 19 of the guide Z in position to engage with the ends of the sliding bar r. i

The device when used in connection with a matrix engraving machine is adjusted and operates as follows: A raised pattern defining the outline of the shaded character or design to be cut in the matrix is fastened in place on the bed a, the liner being turned up on the hinge rod cl to readily admit of this, The liner is then turned down into place with the guide Z and arm 8 in a plane parallel with the pattern and shifted later-, ally lengthwise of the rod (Z into approximately the proper position relative'to the pattern by loosening the set screw and sliding the instrument with the adjusting screw 9 on said rod, the guide Z and arm .9 having been turned on the pivot screw or pin 7t and locked by the thumb nut 29 in the desired angular position on the supporting plate or block f, for cutting or tracing lines at the desired angle or in the desired direction across the face of the matrix or design. The set screw is being tightened to lock the collar on the rod (Z, the liner is adjusted laterally to exact position by turning the adjusting screw g.

The liner being provided with an index or spacing wheel 6 having the required number of notches to produce the desired spacing of the lines to-be cut orv traced and the arin 8 being set with the parts in posi- The lever 9 has a isq.

tion as shown in Fig. 1, to make the first cut or line, the tracing tool or follower of the engraving machine is moved along and in constant contact with the front edge of said arm from one side of the pattern to the other, its movement being limited by the raised shoulders or ribs of the pattern defining the outline of the character or design. This movement of the tracing tool or follower causes a corresponding movement of the cutting tool of the engraving machine across the face of the matrix in which the grooves for shaded lines are to be cut. The lever 9 is then drawn by the operator back against the stop 16 which has been adjusted to correspond with the spacing of the notches in the wheel 6. During thls operatlon the wheel 6 is held in place by the dog 12 while the dog 10 is carried back into engagement with the next notch. The lever being released by the operator, is thrown forward by the spring 15 turning the spacing wheel 6 an interval exactly corresponding with the distance between adjacent notches in its periphery, and the arm 8 is moved laterally a corresponding distance forward or away from the plate or ofi'set m by the belts o winding on the drum t. The tracing tool or follower is then moved back along the working edge of the arm 8 between the outline defining shoulders or ribs of the pattern, causing the cutting tool to make another groove in the matrix parallel with the first. These operations are repeated until the work is completed.

For cutting the shaded face of a matrix of a smaller size than another with a given pattern, the same pattern being employed for cutting various sizes, an index or spacing wheel 6 having fewer notches, spaced farther apart, is used, while for cutting the shaded face of a matrix or design of larger size than another with the same pattern, an index or spacing wheel having a greater number of notches closer together, is used.

The device may be used for cutting, drawing or tracing with any kind of instrument, parallel, vertical, horizontal or oblique, continuous, broken, straight, curved or zigzag lines, directly or indirectly, on paper or other material placed on the bed a or other suitable support.

Various changes in the details of construction and arrangement of parts of the device may be made to adapt it to the various uses and kinds of work to which it is applicable, without departure from the principle and scope of the invention.
