'Specification forming partof I/etters Patent No. 8,291, dated Angus 'January To all u'hom tmcy con-cenni` Be it known that I, J oHN MGA'DAMS, of Bossaehusetts, have invented a new and useful Machine for Numbering the Pages of Account- Books and 'l do hereby declare that the fol- .lowing is a full, clean-and exact description of the same, reference being had to Athe accomparawings, forming part of this specication, in whieh-v Fignre'l is a side elevation of the machine. Fig. 2 is a plan of the same. Fig. Sisa longi` tudinal vertical section of the same, taken' in theplaneindicated by the line A B of Fig. 2. Sim ilar letters of reference indicate corresponding parts .in the several gures.'

rlhe object of my invention is to effect the paging o'i accountbooks in an expeditiousand accurate manner, so that the pile of sheets for a book of any number of pages may be passed each successive page printed in any colored ink in proper position in the upper cerner of euch margin of the sheet and on both sides.

A A A in the several views represent the frame-work of the machine. B B is the platform on which the sheets (represented by red lines in Fig. 3) are placed to.be fed into the machine. The types a a, with the various numbers on their faces for printing the sheets on one side,y are set' in the blocks b b, which are connected by links c c,- so that the said blocks and links form two parallel chains b b c c b b c c, containing two continuous lines of types. rI wo lines of types are used for the purpose of printing simultaneously ,two corners of one side of asheet, each side of a sheet forming two pages of the book when the sheet is folded. The links/e cof the two chains fit ever proper teeth en the peripheriesof circular lplates on each endof the imprinting-cylinder d, Figs. 1,2, 3, which cylinder prints the numbers on by means of the types a a, the types being so arranged in the two chains as to accommodate the folding of the sheets in the binding of the book andthe number of sheets used in a fold,

ot' the pages will follow each other in proper order, and the chains being stretched round the vcylinders d and C, as shown in the drawt12, 1851; Reissue No. 523, dated Fulcrum in ,theframe-work and is drawn up after' each impression by the spiral spring f.v (Shown in Fig. l.) rI his treadle acts upon the imprinting-cylinder through the agency of an elongated hooked pawl, g, which projects upward from the treadle, and whose hooked end engages with the teeth ofthe ratchet-wheelh on the imprinting cylinder. The :sheets are fed up separately from the table B B until their edges abut against the' edges of the two types which have just made impressonsl'lhe treadle is then-depressed and turns thegizfn-l Aprinting-cylinder d until the succeeding two types come into proper'position, when the sheet is fed along by hand and the impressions are produced vagainst'the'periphery of the roller/t', arranged just beneath thesaid imprinting-cylinder d.' The two pages of the upper side of the sheet having been printed in this way, the sheet passes to the lower imprint-` ing-cylinder, `k, round which and round a cylinder, m, both parallel with cylinders d C, there are stretched two type-chains, l l, carrying the types for printing the two corners of the lower sides ofthe sheets, said type-chains being similar to those before described for printing the upper sides of the sheets. The imprinting-cylinder k is turned at proper intervals by means of a chain-belt, O, which passes from the roller to it, said roller t' being turned by the'pressure on it of the upper type-chains as they are moved by the Aaction ofthe treadle. The second impression that is to say, the impression ou the under side of each sheetis produced by means of a roller, p, whose journals are Varranged in swinging boxes q q. (See Figs. 2 and 3..) Theseboxcs are connected by rods fr to the periphery ot a drum, S, as shown in'Figs.. l and 3, which has a rockin g motion rimparted to itfrom the treadle e by means ot the rod u, (see Fig. 1,) connecting its peripherywith the treadle.' The depression of the treadle draws down these boxes, and consequently the roller p, which is thus caused to press the sheet on the face of lthe types in the two 'typechains l l, and produces the iinl'iression on the under side of the sheet. After the under side of a sheet has been printed, as above described, the sheet is conveyed downward behind the cylinder k by means of studs or pins c', secured in wheels j' ings.. The imprinting-cylinder d is turned by f, which are iit-ted to turn loosely on the said cylinder. The manner in which this is eiected is niist'mtsdby the positional which um pins and the sheet are shown in red dotted outlines in Fig. 3 The wheelsff'are turned to' effect this afterthe' limpression'and'wh'en the tread'le 'rises,yby means-of rods b. b', which connect.

'the' said wheels with the periphery of the drum. S.. There.shouldbebands'of moleskin, brother sui-t'able'soft substance, as shown at e! e.,'-passinground the roller p, against which' the-iguresprmted onthe vupper side of the sheet come, and-:ion which a little ol the ink is :tak-embutthis iis .carried along on :the baud after leach i-mpressiomanddoes not comeback again until it 'is' dry. .A

' By the use of t pe-ch'ains it will .be appar-r .enti am enabled to employ imprinting-cylin ders of small' diameter, so that the arrange ment can be made conveniently for paging or printing on both sides of the sheets in lone machine; but in lieu of theseehains plates of large diameter may be fixed on each end of the imprintingcylinders, with socketsfor the types.

In they machine above-described' an essential feature consists in a new principle or mode ot' arran gi ngand operating num'eral types for the paging ot books-that is to say, arranging ,the types, of which there is. a separate one for leach of the vseveral numbers froml to the highest number required to include all the .pages'ot' a book, in a serial order, in continu ous lilies one belnnd another, and bringing f them successlvely and separately to a fixed position at the point of impression, where each meets lts sheet and performs its work and then. passes on out of the way, no more tobe employed in the paging of the same book.

The serial order in which the types are ar,

ranged may be varied according to the num-- ber of sheetsl used in 'a fold or section ofa book. In printed books a "si gnature,. as it is termed,- mals a section. of a bookin binding, but in account-books there are no signatures, and the number of `sheets or leaves ina -sec i tion' or fold'may be varied to lsuit the Ithickness of the paper -or. any of the other conditions of the' manufacture, and the succession ber ot' sheets, and is inea great measure arbitrary,-as is welllknown to practical book-bind A ers and printers.

Before the invention of my principle orinode of arran ging and operating the numeral types, l,the mechanical means used .for paging accountlbooks consisted mainly of a number of plates with numbers cut,- molded, or engraved -upon them, arranged side` by side and. operated by a system ofpermutation, to print Y the higher numbers, when they are wanted.

above the 9 digits or 'above the number 99'.

The lnecessityfor this permutation system,

-as itis technically termed, is entirely obviated by my improved arrangement, and the types' of the several` numbers are 'brought successively, each independently of all others, to the numbering of their specific sides or pages of the leaves ofthe book, as liereinbefore specified, and bythisimeans I am enabled to number two pages at a time on the saine side of the sheet and to number the two sides of the. sheet while itis passing once through the machine.

What Iclaim as my invention, and-'desire to secure by Letters vIat.ent,.is' v 1 The mode of arranging and operatin the numeral types for printing the pages of the Awhole book substantially as herein describedto wit, arranging the types of 'the several numbers fromyl to. the highest number required in a serial order, in one'ormore continy nous lines, one behind another', and bringing them upsiiccessively and separately to the pointot impression-` so that the Vtype of each number is independent ofall others and usedalone and but once inthe paging of the whole hook, and all othersl areout ot' the way, and this I claim whether said types are fixed in a chain or chains or in any othermanner by which the same system of .operation is obtained. L

2. Arranging two type-chains, or continuous lines of type'parallel with `each other, at a proper distance apart,and with the' types in proper serial order and operatingy the same simultaneously, substantially as'described, to print-the numbers of two pages simultaneously on two opposite corners ofthe same side of a sheet. 1

3; 'Ihe` arrangement of two'pairs of type.v chains or continuous lines of type, substantially as described, to` print the .numbers ot two pages on each side of a sheet while the ,sheet is passingoce through the' machine.. of types must be varied according to the num JOHN MGADAMS..
