Application AprifE, 1948, Serial No.18,963 f This invention r lates, to printers t ols. and more particularly relates to an accessory tool for a printers-saw to aid a type compositor in ar ranging various units in a printers chase to corn form to desired-angular relationships.

In the printing art,- particularly in connection with display advertising, it is common to have lay-outs of cuts and inserts which arexset-=at angles with respect to each" other and with respect to the borders of the page on which they are printed in order to be, 1110174: attractive or arresting to the eye. In following such lay-outs, a type compositoror printer arranges in a chase the cuts, blocks of type, borders, and like material which are to be printed, and fills in around and between them with members compositely forming a base and known according to size and shape as slugs, leads, rules, and base blocks. When the chase is filled, it may be clamped. in a printers form with the units forming the composition tightly wedged together. However, as the sizes and relative angles of the printing units. can not be foreseen, it is-the usual procedure to claims. (01. 29-69) take measurements of angles and sizes from the and base blocks from type metal, wood, or other suitable material on a .printers. saw. Drawing the outlines of the blocks and rules on a piece of type metal or the likeand then arranging and holding the material so as to cut accurately to the lines consumes a rfiatdeal of time and is not conducive to the required degree'of accu-. racy. Often a printer will judge the required sizes and angles by eye and trim his base mat rialby rial nd err r ntil it is n atisfactory form.

It is an objector this invention to provide an angle guide which will reduce the time and labor consumed in measuring. and cutting angulated base blocks and rules.

A further object of the invention is to provide an angle guide which may be applied directlyto lay-out copy and set-in conformity with a desired angle thereon without the necessity of scaling such angles, and which may then be applied to a printers saw to guide amargin of a piece of material to be cut at said angle to the saw.

Another object of the invention is to combine in an accessory'tool fora printer's saw an angle measuring device and a clamp for holding work at a measured anglewith relation to the saw.

Still another object Qf-. the invention is to provide a clampfor, holding Work at a desired angle to a saw. which will permit the cutting of very thin rules and base blo k at very acute angles to the saw;

The invention possesses-other objects and tea-e tures of advantage, some of which, with the tore-i going, will be set forth in the following descrips. tion of the preferred form of my inventionwhichv is illustrated in the drawings accompanying and-- forming part of the specification. It is to be understood that L-do not limit myself to the showing made by the said drawings and descrip-.- tion, as I may adoptyariationsofthe preferredform within the scopeof my invention as set forth in the claims. 1 7

Before entering on a description of the em: bodiment of my invention which has been chosen for illustration and description herein, a gen eralized description of ,a printer's saw .and its, method of operation will begivento aiiord a bets, ter understanding of the [manner in which. my angle guide is applied thereto. A printers saw, as shown in Figure 1, comprises a sawbed or table 6 having aguidevvay' or groove 1 .A cire c'ular saw 8 is mounted in a" slot, not shown, in an ofi'set margin of the guideway l, and parallel to the guideway, with the'upper margin ofthe" saw extending above the bed 6. The saw 8 may; be driven and may be vertically adjusted by any suitable means, usually located below the bed 6? A bar or key'9 slides in the guideway l and has: a right-angled arm Ill, generally termed a gauge, which slides upon the surface of the bed 6. A'- work guide H, with an arm l2 parallel to the guideway T, is slidablymounted'on the gauge Ill; so as to-be movable towards and away from the guideway "l. Thearm I21 may be secured at 'a' selected spacing from, thesaw 8 by mechanism" clamping the work guidell to'the gauge I0, such as a rack I3 and a'pawl and lever l4, and is also. movab pa l el to the sawb movement of th gauge and the key 9 along the ew y 1., The gauge I!) has a central ridge is which divid s its upper surface into benches l6 and I'I.. A clamp r 18 is moun e es d e h6 9 n. the guideway i so as to bemovable towards and: away'from the guage 1.53, dmay be amped-t9 the key 9 by lockingmechanism operated by-a lever l5). 1--

Slugs and leads-may eas b ip PF- l 3 saw by placing them on the bench I1 and clamping thembetween the clamping arm l8 and the ridge I5. They may then be cut squarely by moving the gauge l parallel to the saw 8, with the key 9 sliding in the guideway to guide the movement. But if it is desired to cut a base or rule at an angle other than ninety degrees, it is necessary to mark the block from which it is to be cut and then to hold the block on the arm I2 and the platform l6, bracing it against the ridge i so that the saw will pass along the mark.

My angle guide, as shown in detail in Figures 1 2 to 4, inclusive, comprises a protractor plate having a semicircular margin 2| marked with a scale 22 graduated in angular units. The zero or reference line is preferably at the mid-point of the semicircular margin 2|, which affords a range of ninety degrees on each side of the reference line. The plate 20 has a rectilinear margin provided with a bar or flange 23 which forms a straight edge perpendicular to the axis of the plate bisecting the margin 2|. A clamp hook 24 is secured, as by welding, to the upper margin of the flange 23 and has the form of a hooked finger bent outwardly and downwardly so as to fit-the arm H of the work guide I. A set screw 25 is threaded in the distal end of the clamp hook 24, and preferably at an angle to the horizontal, to allow space for and easy access to a knurledv head 26 by which the set screw may be operated to clamp the hook 24 to the arm |2.

vAn index arm 28 is pivotally secured to the plate 20 by a pivot pin 29 set at the center of radius of the scale 22, and may be clamped in any desired radial position by a wing nut 3|], the shaft of which extends through a curved slot 3| in the plate. Preferably the index arm 28 is secured to the lower side of the plate 20 and extends beyond the curved margin 2|. The outer end of the index arm 28 is provided with an upstanding column 32. The column 32 preferably has a shoulder portion 33 overlapping the margin 2| to provide an index in close association with the scale 22. Secured to the outer surface of the column 32 and at a right angle to the axis 01' the index arm 28, is a plate 34 which has a flange 35 along its lower edge. A stud 38 is adjustably threaded in the upper end of the column 32 and has a knurled knob 31 rigidly secured to its upper end. The knob 31 is provided with a wide lower face 33 which extends beyond the column 32 into peripheral alignment with the outer margin of the flange 35 so that the face 38 and flange 35 serve as opposed jaws between which a piece of work material.

such as a block of wood or metal, may be clamped.

The flange 35 serves as a ledge to support the work material and is tapered towards one end. to be substantially flush with the plate 34, as shown at 39. The tapered end 39 extends towards the gauge II! when the angle guide is secured by the clamp hook 24 to the arm l2.

With the above-described angle guide, the cutting of bases at angles other than right angles is greatly facilitated. It is not necessary to mark the block which is to form the base. or even to measure the required angle in degrees. The angle guide may-be. removed from the arm l2 and may be placed directly on the lay-out copy. Any line on the protractor plate 20 normal to the reference line thereof, such as the flange 23 or a line connecting graduations of equal magnitude on the scale 22, may be placed parallel to one border line of the required'base or .to lanyline 4 parallel thereto, and the index arm 28 may then be swung to bring the plate 34 parallel to another border line of the required base, the arm 28 then being clamped in position by the wing nut 30. The angle guide may then be clamped on the arm l2 by the set screw 25. A block or work piece of base material is placed with one side against the plate 34 and is clamped between the knob 31 and the flange 35.. The saw 8 will then be at the proper-angle to the side of the block which is against the plate 34, and the required base may be cut.

Alternatively, when the required angle of the base is known or may otherwise be measured, it

may be set 011' .on the scale 22. As the zero line of the scale is perpendicular to the saw 8, the plate 34 and the side of the work block clamped thereto will be at the required angle to the saw.

Because the knob 31 and flange 35 extend only a short distance beyond the plate 34 and grip the work block only by small portions of its upper and lower surfaces, very thin pieces may be cut from the block, and at very acute angles with the side of the block. It will be understood that the width of the piece cut from the block may be regulated by moving the work guide I one way or the other on the gauge Ill in the conventional manner.

The tapered end 39 of the flange 35 permits thin, acutely angled pieces to be cut with a minimum of splitting or chipping at'the apex of the cut pieces as it allows the saw 3 to be brought practically to the face of the plate 34 which backs the work piece.
