To all whom zltjnay concern:

Be it known thatLARrHUR HERBERT ALEX ANDER, a subjectof the: Queen of Great Britain, and a resident of London, England, have invented an Improvement 'in Indexing-Machines, (for which I have secured patents in Great Britain, No. 15,067, dated August 10, 1895, and in Germany, No. 91,672, the date of application being July 8, 1896, and the date of issue being April 23, 1897,) of which the following description, in connection with the accompanying drawings, is a specification,

like letters on the drawings representing like parts.

My invention relates to improvements in indexing-machines, of machines for cutting through a plurality of thicknesses of paper, being particularly intended for use in properly indenting or cutting the edges of books that are to be lettered as indexes or otherwise marked for the purposes of accounts, memoranda, letter-copying, tables, or alphabetical or other arrangements of subject-matter.

My improvements relate to machines in which the book or material to be cutis clamped fixedly in position and the cutting-tool is made to travel step by step along the desired line of cutting and in which mechanism is provided to actuate the cutting-tool to make a cut at each step, my improvements being especially intended to simplify the mechanism and to render the step by-step movement accurate, expeditious, and capable of perfect adjustment with any degree of nicety and accuracy desired. In machines of this class as heretofore devised there has not only been a considerable complexity of mechanism, but also an attendant inaccuracy or uncertainty of operation, particularly with reference to the intermittent travel or forward movement of the cutting-tool. Accordingly with a view to obviating these objections I have invented a guide member or pattern-surface to cooper ate with the tool-carrier,'so as to make the step-by-step movement absolutely uniform and unvary-in g for a given index or succession of cuts.

My invention also includes a tool-carrier or slide, also various details of improvement,

including a width-gage and other cooperatof the tripping arrangement.

7 7, looking toward the left. 'spective view of the width-gage.

' ing gages for positioning the work, clamping mechanism to hold thework, positive operating devices to actuate the cutter, and improvements in gage-indicating attachments.

All these and other improvements of my invention, as well as the details of operation and advantagesarising therefrom, will be hereinafter more particularly set forth, and

the invention will be defined in the appended claims,formin g a part of this specification, reference being had to the accompanying drawings, illustrative of the preferred embodi 11161113 of my invention.

I11 the present embodiment of my invention, G designates a suitable standard or support, shown as consisting of end legs held together by tie-rods g and having brackets 7t projecting forward at its front side to support a worktable II.

A designates a casting or frame mounted on the standard G and provided with suitable parallel ways A A, between which the toolcarrier or slide 13 slides in its intermittent travel from left to right across the machine.

As herein shown, the upper way or guidesurface A is supported above the lower way A by means of blocks A one at either end thereof, secured by nuts a and studs a, the latter being screwed through the blocks A into the casting or frame A for convenience of manufacture and rigidity of construction.

The work-table is cut away at 7t (see Fig. o) to expose the slotted openings 71 formed in the upper ends of the brackets 71 to permit the required adjustment therein of the workclamp ll for properly positioning the work adjacent the cutting-tool. The means of adjustment for this clamp are best shown in Figs. 1 and 2, where it will be seen that I have mounted sleeves m in the slots 79, these sleeves being provided with flattened sides, as indicated in Fig. 3, and having llanges 7t at their lower ends and provided with clamping-n uts 7r at their upper ends, by means of which they may be fixedly positioned as desired in said slots. Through these sleeves bolts it are passed, prevented from turning by means of a transverse pin (not shown) entering a slot in the sleeve, the said bolts carrying at their upper ends the work-clamp ll by means of the nuts 7L and having quick-clamping attachment by means of cam-levers 7v, pivoted thereto at their lower ends.

13y reason of the attachment above described it will be evident that the work-clamping bar 11' may be accurately adjusted up or down and toward or from the cutting-tool, as required, for any variety of work, large or small, and may then be quickly opera-ted without further adjustment simply by turning the cam.

A width-gage i to control the width of the indexingor, in other words, to regulate the depth of the cut into the edges of the book which is being indexed-is pivotally 1nounted by means of links I I at its respective ends to a projectingledge or base of the casting A, springs '11 i being provided, wound around the pivots, to automatically throw the width-gage out of the path of the tool as the latter is caused to descend. For this purpose a catch i pivoted on a pin i to the casting or frame A, is provided, adapted to engage an ear 't' of the link I to hold the same normally against the removing action of the springs t' and i, the tail end t of this catch beingengaged by an arm c fixedly mounted on a moving part of the tool-operating mechanism, so that when the tool is actuated its arm c will depress the tail end i of the catch '5' and thereby release the width-gage I" just before the cutting edge of the tool reaches it in its descent and permit the width-gage to be automatically removed by its springs out of the way of the said cutting-tool, the width-gage, however, is retained in its proper adjustment to hold the work as required until the tool begins to bear upon the latter in its cutting operation.

In addition to the work-clamp and widthgage already described I provide an end gage K, (shown in detail in Figs. 11 and 12,) against which one end of the book or other article to be operated upon is placed or registered preparatory to being clamped beneath the clamping-bar 11 on the work-table. This end gage is shown as consisting of a dovetailed slide /i:, provided with a fence 7.; and capable of ad justment along a rib 7& on the frame A, on which it can be clamped by a set-screw 7. preferably adjacent a suitable lead or stick J provided in the path of the cutting-tool and against which the latter may cut in its descent.

The eutting-tool may be of any configuration desired to form the required notch or other cutin the book or article being indexed, this tool being shown at Z in Fig. 1 as removably secured at the lower end of a head Z on a hollow tool-bar L, normally held in raised position by a contained spring bearing at its upper end against a retaining screw-plug Z and at its lower end against a shoulder Z, fixedly supported in aguidearm L by means of a bolt t", the tool-bar L moving freely up and down over the latter in the guide'arm L by means of vertical slots l", formed in its opposite side walls, as indicated in Fig. 13. The reciprocating or cutting movement of the tool and its toolbar is accomplished by the engagement with the latter of a transverse pressure-bar F, (see Figs. 1. and 2,) supported at the upper ends of rods E E, sliding vertically in suitable guides a at the base of the casting or frame A and guides (Z projecting from the blocks A the movement of the rods E E being limited by collars e a, secured thereon. The pressurebar F is reciprocated by means of a treadle E carried by a shaft E and having at its front end a treadle-board E and at its rear end counterbalance-weights E E the forward end of the treadle being connected by means of links F. to the vertically-sliding bars E E, so that when the operator depresses the front end of g the treadle he thereby brings the pressure-barF into engagement with the tool-bar L wherever the latter may be in its travel across the face of the machine beneath the pressure bar, and upon releasing the treadle the counterweights E E at once raise the pressure-bar and permit the tool and its tool-bar to be lifted from the work by the contained spring Z The guide-arm L constitutes a part of th tool-carrier to which I have already alluded and is mounted'on a sliding portion'B thereof, (indicated in side elevation in Fig. 1 and shown in further detail in Figs. 8, 9, and 10,) the details of this part of the tool-carrier being provided to enable the tool to be definitely moved forward step by step as required by a predetermined pattern D, the latter being shown in detail in Fig. 18, where it will be seen that it comprises inits preferred form a symmetrically-arranged divergentseries of grooves or ribs 01 these grooves being shown as diverging symmetrically on either side of a central, vertical, or transverse groove (1 The pattern-surface will preferably be in the form of a cylinder, as shown in Fig. 1, although it may equally well be in the form of a plate, as shown at D3 in- Figs. 24 to 26. The surface of the cylinder or roll D, Fig. 1, will be provided with a series of grooves at, one of which, preferably the central one, lies wholly in a plane at right angles to the axis of the roll D, while the other grooves d diverge at such angles as to equally divide lines drawn upon the surface of the roll parallel to its axis.

The slide B operates between the guideways A A, as before stated, being provided with retaining-flanges b, and has one or more pins operated transversely therethrough to engage the grooves 01 of the pattern-surface, two pins being herein shown, (marked, respeotively, B B so that in the preferred op eration thereof one or the other will be in engagementwith the pattern-surface, these pins having lateral movement relatively one to the other, as will presently be described, so that when the tool-carrier is released it may be intermittingly pulled forward by its weight 0, connected thereto by a chain c, passing over a pulley c and secured thereto at o In order to permit the relative lateral movement of the pins B B just alluded to I have mounted these pins in sliding portions, the pin B being mounted in a hollow plunger Z7 and the pin B being mounted in a plug b capable of longitudinal adjustment within the plungerb by means of athumb-screw b the latter having threaded engagement with a nut b mounted on the outer end of the plunger, a check-nut 12 serving to fix the parts in any desired adjustment, and the thumb-screw being held against removal from the plug b by means of a plate I), attached to the end of the plug and receiving in a recess therein a reduced portion or neck 12 of the screw, whereby the latter is free to rotate, but is prevented from moving longitudinally relatively to the plug.

The plunger 17 and its contained plug 19 are mounted to reciprocate from side to side within the slide B ina recess or bore 12 formed therein, and are held within this bore by means of a plate b permanently secured at one end thereof, and by a nut b also permanently secured at the other .end thereof, an adj ustment-screw Z7 being centrally mounted in the latter nut and fixed in its adjustment by a check-nut Z7 to limit the travel of the plunger to the left, viewing Fig. 8, a

spring 19 being provided normally tending to force the plunger 19 in an opposite direction against the plate I) at the other end of the bore 1).

A graduated scale Z2 is supported by a pin b" on the slide and cooperates with a diigided or graduated head 19 of the screw Z2 to enable the operator readily to adjust the stop accurately as required.

,By reason of the construction just described it will be evident that when the pin B is in engagement with a groove 01 the weight 0 will pull the slide over to the right until it is stopped by the stop-screw 12 the amount of this movement of course being capable of various degrees of adjustment simply by turning the screw forward or backward,

and it will be evident that when the pin B is out of engagement with a groove (1 and the pin 13 is in engagement with a groove 01 the weight 0 will pull the slide to the right until the plug 5, its thumb-screw b nut b and the plunger 19 are all in close relation in resisting engagement with the adj ustmentscrew 5, which regulates the amount of reciprocal action or lateral movement of the pins relatively to the slide 13 as the latter is intermittently pulled along by its way when once the machine has been set for the purpose of cutting a certain-sized step. The slide 19 plunger b and pins B B move as a whole in the slide B, but have no movement in relation to each other due to their said movement inslide B.

Referring to Fig. 19, a modified form of se-' cu ring the relative adj ustment above referred to may be seen, comprising abore 19 in which a plunger 1) and plug b are reciprocable, the latter carrying the pin B and being capable of adjustment by means of a thumbscrew Z9 and the former carrying the pin B and being limitqd in its movement by a screw Z7 as before.

Referring to Figs. 9., 10,, and 13, the preferred mechanism which I employ for operating the pins 13 3" is shown as consisting of flaps ff, centrally hinged to studs f and respectively engaging at their lower ends the pins 15 13 between the heads b and shoulders 11 of the latter, (see Fig. 13,) the flaps being actuated by springs f wound around their hinge-pins, which normally act to cause the flaps to insert the pins 13 1 into the grooves (1", these ilaps being engaged at their upper ends by the inclined end of a projection Z, carried by the tool-bar L, as the latter descends in its cutting operation, thereby turning the said flaps in an opposite direction to cause their lower edges to withdraw the pins l3 13 from the grooves (Z in opposition to the tendency of their springs to insert them therein.

It will be understood that at the same time that the tool-bar and its projection Z withdraw the pins from the pattern-grooves the pressurebar F by its pressing engagement on the end of the tool-bar firmly holds it and the tool-carrier against any lateral movement which would otherwise be occasioned by the weight 0, but although the tool-carrier itself cannot move the plunger Z) moves at once as soon as its pins are released from the patterngroove by reason of the pressure thereon toward the right of the compressed spring 11 this spring having been compressed and the adjustment screw Z) having been pulled against the plunger t by the weight 0 when the pin 13 was first engaged with its patterngroove and before the pressure-bar F operated the cutter-bar, and therefore this forward movement of the plunger within the slide of the tool-carrier carries the plunger and its contained plug, and hence the other pin 13 against the plateli and into position to permit the pin 13 to engage another pattern-groove as soon as the cutter-bar has been allowed to rise sufficiently to disengage its projection Z from the ilapf, further upward movement of the pressure-bar until the cutter-bar is released then permitting the tool-carrier to be moved a step to the right by its weight C,this movement again compressing the spring (1 The next downward movement of the pressure-bar holds the tool-carrier from lateral movement, as before, and at the same time disengages the pin B from its holding relation with the patternsurface, so that the compressed spring I) at once shifts the plunger Z) to the right, as before,bringing its pin 13 into alinement with another pattern-groove, into which it is inserted by its spring upon the release of its lap by the upward movement of the tool-bar, before, and, finally, upon the further upward movement thereof and of the pressure-bar F the tool-carrier is again free to slide forward a step to the right and again bring the pin 13 into alinement with another pattern-groove, the process being thus repeated step by step until the book or other article is fully notched as desired.

In Figs. 20 to 23 I have shown other means for accomplishing the desired movement of the pins B 13, comprising a flap f and a leverf pivoted on ears 1'', the former being actuated by the inclined end of the projection Z, as before, on the descent of the tool-bar, and the latter being actuated on the ascent thereof by a pin l extending from the projection Z and engaging the inclined upper end of the lever f*, as clearly shown in Fig. 21. The [lap f has a spring f wound around its l1inge-pinf ,which operates to insert the pin B into a groove (1" of the pattern-surface, while the pin B is forced into engagement with another groove of the pattern-surface by a spiral spring f, contained in a recess formed in the tool-bar guide L and bearing against the extended forward end of the pin B".

The arrangement just described permits one pin to enter a groove when the other pin is withdrawn from its groove of the patternsurface. The object of the second pin is to divide the step in half and so get smaller steps without making the grooves closer together, which would leave the ribs between too thin to be strong.

For steps from one-fourth of an inch to seven-eighths of an inch each in length (that is, books from six inches to twen ty-one inches long) I use the left-hand pin only, the other remaining held back by its cam-lever. This makes the setting considerably simpler for ordinary sizes.

In order to permit the pins above described to be held out of engagement with a patterngroove whenever desired, I have provided cam-levers f pivotally mounted adjacent to the pins or preferably adjacent to their actuating-flaps, these cam-levers having inclined lower faces f to engage a lugf on the flap, and thereby permanently tip the latter to withdrawits pin when the lovers are turned down and hold the pins in inoperative position until the said cam-levers are returned to their upright position, as shown in the drawings. The provision of these eam-levers permits my improved stepby-step mechanism to be operated when desired by means of one pin.

In order to indicate to the operator the progress that he is making in cutting the book or other article being notched or indexed, I have mounted 011 one side of the guide-arm L a flanged wheel at 011 a suitable pin m, and between this wheel and a shoulder m I place a ratchet-wheel m the flanged wheel on being tightly placed thereagainst by a spring-plate at", set up by a suitable nut m, the periphery of the wheel on being provided with letters, figures, or other indications corresponding to the index being cut, a space being preferably left by the side of each letter for the insertion of the number of pages that letter or character is to have in the index. A pawl m is pivoted on an arm m carried by the reciprocating tool-bar L, being adjustable thereon by means of a spring or rubber band m" and set-screw m so that each time the tool-bar descends it will turn the ratchet-wheel more orless, according to the adjustment of the pawl, and the rubber band or spring m will permit the pawl to yield in its upward movement and click over the ratchet without rotating it backward.

In Figs. 1, 2, and 3 I have shown the pattern-surface as cylindrical in shape, being cut away at 01 (see dotted lines, Fig. 1) for the purpose of making the pattern-cylinder lighter. This cylinder or roll is journaled in brackets 01, projecting in a rearward direction from the blocks A and is provided at one end with a suitable hand-wheel d, with which to turn it inits bearings, one of the latterbeing split and provided with ears d and a bolt d with which to clamp the roll in any desired position, the roll being provided with one or more graduated scales 01 which may be read over the edge of a reader-plate (1 secured to a fixed part of the frame, these scales being so arranged that the numeral or numerals alined with the-reader-plate indicate the data for the horizontal line across the pattern-grooves in alinement with the pins of the tool-carrier; I

In Figs. 24 to 26 I have shown the patternsurface in the form of a plate D movable up and down in guides D by means of a hand-wheel d' mounted to rotate in a perforated lug 11 and having threaded engagement at 01 with an ear d on the back of the pattern-plate, as clearly shown in Fig. 26, so that the pattern grooves, moving up and down in a vertical plane past the pins of the tool-carrier, cooperate with thelatterprecisely the same as the curved pattern-surface of the form thereof shown in Fig. l.

The operation of my machine is as follows: The pattern-surface is first set, and todo this the pins are withdrawn and the slide moved to the extreme right of the machine and afterward brought up to the left-hand groove. The machine-is first set to cut the desiredsized index by moving the tool-carrier to the extreme left ofthe machine, so as to engage its pin B with the last pattern-groove d, the spring Z9 being compressed by the action of the weight 0, so as to hold the stop Z9 in contact with the plunger W. The tool-carrier is then held against movement, the pin B being released from its groove by hand, and the thumb-screw b and adjustment-screw f are properly adjusted to bring the pin B in front of the next pattern-groove-that is to say, the

adjustment is so made that when the pin B is in a groove and the plunger is at the same time against the stop 11 and thereafter the pin B is withdraw-n from its groove, so as to be projected to the right by its spring Z9 the pin B will be brought directly in front of another groove. This is the method of adj ustment for short books.

To set the machine to cut an index of a given length of book or article of six inches or over, the pin 13 only is used, the other one being rendered inoperative by turning its flap-lifting cam-leverf downward, and then, the pattern-surface having been adjusted until the graduated scale registers the desired size against the reader d the tool-carrier is slidover to the extreme left of the machine, as before, until its pin B enters the last groove dflwhen the adjustable stop 12 is then set by its graduated scale 1) 19 to the same adjustment as was indicated by the reader d The pin will then be withdrawn from the pattern-grooves each time the tool descends, and the spring b will move it along to the next groove, while the pressure-bar holds the toolcarrier against lateral movement in a manner which will be readily understood.

I have arranged and described my machine to cut twenty-four steps-that is, the cutting is arranged to correspond to the usual alphabetical indexes; but of course it will be understood that any other number or arrangement can be readily substituted or added.

The machine having been properly set to provide the requisite step-by-step movement when it is being operated, the book is clamped beneath the clamping-bar I-l' simply by turning .the cam-levers it the said bar having been adjusted to the correct thickness by means of the nuts 77/ and the width-gage l is swung by hand against the front edges of the book, being moved until its ear 7? is engaged and held by the catch i to properly position the same for the cutter-tool, the book being also alined at its end acccurately with the end gage K. Having thus properly positioned and secured the book, the operator depresses the end E of the treadle, thereby causing the pressure-bar F to descend on the upper end of the tool-bar L, the bracket 6 in the meantime having engaged the end of the catch i thereby releasing the widthgage and permitting itto be moved out of the way of the tool by its actuating-springs. The tool descends and cuts the required notch or perforation, the projection Z meanwhile having released the pin or pins 13 B -from the pattern-surface, so that just before the tool reaches the bottom of its stroke the said pins will be moved along to the right the required distance to cooperate with the patternsurface in permitting the tool-carrier to be moved by its weight 0 as soon as it is released by its pressure-bar and permitted to do so. The first out having been made, the last section in the index will be lifted out ofthe way of the tool by the operator and the second cut will be made. The next section of the index will then be raised or turned out of the path of the tool and the third cut will be made, and so onwith the successive cuts, the entire indexing being quickly accomplished in progressive order with absolute evenness and precision of cut and of spacing without the possibility ofany mistake or inaccuracy.

While I have herein described the preferred embodiments of my invention and ICC have explained all the details of construction thereof in order that the same might be clearly apprehended, yet I wish it understood that I do not limit myself in any way to the precise details of construction herein set forth, inasmuch as many changes therein may be resorted to and the combinations and arrangements thereof may be considerably varied within the spirit and scope of my invention.
