This invention relates particularly to mechanism for simplifying the work of indexing books. An object of the invention is to provide a means for assisting in the opera 5 tion of placing. index tabsfon thumb-index books by presenting them to the operator I presents the index tabs in proper order and one at a time, and which is fully' describedin the following specification, and-shown in the acompanying drawings in which vFigure 1 is a top "plan View of a table equippedwith the invention and showingithe stationary top partly broken away; H y

Figs. 2 and; 3 are enlarged vertical sections on the lines 22 ands-3 of Fig. 1;

Fig. 4 is a side elevation partlyin section; -Figs.i 5 and dare. enlarged details of the ratchet mechanism'jandl "Fig. 7 is a partial view of a book having a thumb index.

' The embodiment illustrated comprises a table 10 suitably mounted at a suitable'height above the floor (not shown) on supports f v V opposite the opening 15F-and places the book B to be indexed onlthetable in front of her.l

(not shown) ,1 before which the operator is preferably seated. Uponthe table 10 is mounted a casting 11 to which is secured a stub axle 12 upon which is journalled a rotat able member 13. This member has a series of openings 13Tand beneath eaoh'of these has asloping surface 1 1: terminating'in aflat horizontal portion 14c which preferably ex tends beyond the circular rotatable member 13 for a purpose laterv to be described.

Above the rotatable member 13 is a stationaryplate 15 having a-single opening 15 facing the operator, and which isadapted to register successively with the openings 13 as the member 13 is rotated.

The rotatable member 13 hasa circular ratchet 16 secured thereto on the under side and this hasa series of ratchet teeth, prefer-f 5 ably one for each of the pockets 14. A11

is secured a pocket 14 preferably of sheet metalsoldered or spot-welded to the member 13. The outer portion of the pocket 14,

operative leverflf is fulcrumed at '18 between "brackets 18 depending ,from the table 10 and steadied by a brace 18?. This leverhas a ?ratchet arm 19;pivotally mounted. at the supper end by means-0f a pin 20. fThis arm c'arries'a ratchet finger21which is urged to-- ward the ratchet by means 0f a spring 22,

whichis connected atone endto the lever17, and at the other to the outerend ofthe arm '19." This spring serves the double purpose of urging the finger 21 onthe outer end of the arm 19 into engagementwitl1;the teeth of the ratchet lh, and of-normallyreturning the operating lever 17 to the full line position shown in Fig. 4:. -Themovement of thelever 17 is regulatedby means. ofthe adjusting screws 24 and'25,the former serving to place the openings 1'3 in registration with the ,upperiopening s' l5i' 1 a I i y The tabs, as A markedFMathF, are located inone of the pockets,;ajs the one shown in the},

uncovered position Fig. 1. It will be noted, that the opening 15 is deeper than the opening 13 thereby providing aspace 13"" on the member 13 which can be labeled,-as by the term Mathfi', to indicate what tabs are containedin that-pocket; 1 1 a, I

The operator sits'gin -front of the table 10 bearingthe word Math. This tab is then drawn upthe inclined portion v14*" of the pocket by the moistened finger of the operator and turned to, the,proper position on the lip 1d; The gummed tab is then moistened as by means of a moist sponge (not-shown).

and pressed upon the top :leaf of the book B (Fig. 7 g at a point previously marke'd sothat it will register with the thumbindexopening previously cut in the edges of the'preceding Pages- The operator. thenactuates the lever 17 thereby bringing before'the opening 15 the next pocket 14 containing tabs; It may hap-.

pen all'of the pocketsarenotnsed, irr.

- ivliich case blank pockets are interspersed between the filled pockets. .lV hen it happens presented next, and places a finger upon the thumbopening of the book here the next that aiblank pocket'appears,;the operator actuates the rotatable member 13 once more, thereby bringing the next pocket into registrationrwith the opening 13. -Th-e'se pockets are filled with the appropriate tabs so that the] tabs are presented to the operator one after the other invva predetermined order 1 \vhich'is folloivedin openingliipzthe book so that the operator knows which tab vvill'be tab is to be inserted.

Thus it will beseen that a very simple yeti. effective means is provided *for presenting tlie tabs toaii operator in the order in which they are to be inserted in a book,so that the operator is no longer required'to cheese between different tabs in orderto find the cor-o rect one for any particular iiisertion.

While i have shown and a scribed bet a single embodiment of my invention, it is understood that it is capable of many modifications; Changes, therefore, in the constr'uc-- tion and arrangement may bemade 'which'do not depart from the spirit and scope of the invention as" disclosed the appended claims.
