- This invention relates to n. movable slide placed under ,the lifter or liftcrs, in such o, manner that a fresh supply of blanxsenn be introduced under the-lifters atfany moment whenever the lifters begin to rise, without atopping the machine; also, to n pcculinr arrangement of the lifter und table which supports thegum-box, und under which theblnnks are conveyed to the creasing-box in such n manner that thc table itself pulls off the. blanks from the lifters und retains them in n correct posi-tion for the plunger to uct upon; further, to ce1-lain improvements in 'the mechanism employed to impart the desired motion to the gum-box in rolzition to tbc lifter-s, to counterbalancethc corivcyr to creuse, `fold, und press the'envelopemnnd to discharge thcxzjl from the machine wbelrfinishcd To cnnblc others skilled in the nrt tomnke and use this invention, we will proceed to describe it` A represents a frame mnd@ of iron or any other suitable muterinlhnhiohsupports tho working parts of our mnchie. This frame is provided with a. platform, B, and on the top of this platform, nnd supported by small columns, a, is thc tnblc Coiwhieh supports. the gum-box. D. The blanks, u'hich are indicated. in red outlines in lllc various figures, are pliziced or n. Slide or carrier, E, whichinay be provided*withprojeoting lugs 7i, to retnin the suine in the propel' position, and-which can be lno'redin under the gum-box und out from under the suine nt pleasure. lvhen moved out s :xirl slide or carrier is vclear O thc table C, and in such ,a position thnt n fisnii supply of blanks een be introduced without diiiculty. The carrier with the blanks is then pushed buck under the table, nml in tho proper position to beneted upon by the lifters E. These liften nrc Secured in an angular 'psjtion to the cross-head Fl, which is secured to the upper ends of' rising and falling rods, F2. The lower furlced ends of the rolls F cat-eh over o, bar, f, `which is supported by arms, j", which are loosely attached tO n. shilft or rod,f`, and to ywhich un oscillating motion lis'ii|ip:no|l by :icnmfl*, on the main driving-shaft G. As the baif rises by the notion of thc arlnSf,-it cmirios up with itself` the vertical rods F2, :1nd the lil'tois F, and when the bnr with the arms descends the lifters sink down, until they strike either the gum-box or the pile of blsinks en the slide E, or, ifboth the slide and the gum-box are out of thc wiz/ty, thc liftern sink do'wn as fur as the motion of the nrmsflwillllow. vIl: will thus be seen that the litters not upon the blnnks entirely hy their,

own grzn'itygmd consequently they willcomo,` flown upon the blzinks uith the sumo force, no mutter what the thickness Or height oli the -pilc oi`"blnn ksj upon the slidc, cnrrier,'or platform E. The gumlhox l) is plneod loosely upon thc tnblcC, nnditis provided with two gmlguons,icll, which extend into slotted arms, These arms nrc rigidly-,connectedt-O n. rock-Shaft, d", which 'h'isfitsv bearings innlmngors, d, under. the platform B, und to which-nn oscillatingv1-notion is imported from the, mnin driving-Shaft bythe fiction ofo com, d, on :i rising nud falling rod, di',whichconnects.with n-n'urm, d", extcndingfrom tho rock-shaft. L Spiml spring, d", round round said rock-shuftfhas n tendency tocar-ry lthc gum-box buck to its origineLpos-ition as soonas tic action of theL cum-dif? onthe rod da ceases. .The cnui 012-* is; so shaped that the gnm-bo is corrieri forward just when the liflers have reached their highest point, und it is retained under the lifterS until thelntter como down,

tolse up norms nun-nud rise again, to lot the guubbox go'hack. I The lifters thuscharged uilh gam descend, end, by'heing pressed 'einen the blanks, carry one of them up and holdit close under ythe trible C, ready to be teiten eil" 'by the conveyor H. The lil'ters nre slotted, and they pass down through slots'in the table, which leave n. bar, cl, 5to Werl: up and down in the slots of the liftezs. It' a blanlcis carried nlp by theliftcrs, it strikes the lower surface or" timetable, sind it is readily detached from the'liftcrsv and deposited on vthe conveyor. The hor in the slots of the table' materially assists in dctucliing the blanks, and prevents thc-.sumebecoming wrinkled und uneven. The conveyor is provided lwith hooks, la, which catch over thc edge ,of the blanl: und curry theenmc in us vtheconveyor is moved ocrossthe platform B. Small weights, c2, u'hic'h nrc hinged to thc rontredge el' the table C, bear down upon the cndso-Y- euch -blank :is the sume is raised by the litters, und hold the sume il.: such e. position that it will be caught by the hoolisof the conveyor, whether the paper be even or rpefl. Without these wcightsfzznd if the blank is warped, the hooks, or one of the hooks of the eonv'cycl orc. liable to slip under the blank ivithont catching over its edge, and the pape!` is wasted. `rllic conveyor coneiste .ein sonorefmme whichmovesbociiwurd and forward in slides, h, that crc rigidly cttochcdto lthe platform l?. by means of standards or vbreek/ets, lli'.y Motion is imparted to it by the notion of an crm, L, which rises from the rochelmftfi This roclcshrtft receives Ls motion by nn :li-m, h2, which cxtchds from thefsmneovenn com, Il?, on the innindriring-shoit, and which is held in Contact u'ith said com by o. spring, lz, applied under the platform l. The amr/tl* Connects with the couvyer H by u. link, and this link is4 provided with af lnxlnofzenveight, il, which servos to counteract the weight of the conveyor as the some reaches lts extreme position, nml prevents the seine from assuming :i vibrating motion when the machine is worked rapidly. By the action o the conv'ejf'er the hlnnlc is moved forward over" the creasing-box I, and under the plhngel' J, und in order to keep mid blank in the proper position while it lies on the box, und -bffore the plunger hns come down uilen it, two nrnis,'c**, are applied in such a. position that they'cxtend parallel to the edges of the box. The lower edges ol those arms nro intended to be level with, or rather below, the top edge 3f thc gum-bo so that they beer donn upon the ends of the blnnks and hold them in position, :1s shown in lig. 4, yof the druning, :1nd scid. orme may either be secured to the table C, or to, any other fixed p'zirt of the machine. -Thc creasing-box l, consists ol'n an oblong square frame, open at top und bottoni, sons to form two creasing edges, i iii, one :it-thc top and the other :it the bottom. The sides ol' the box are cut open to give access to thc foldingdiagers K. The blank which has been brought over the box I by the conveyor H, is carried down by the plunger J, which is seemed. to :t roflh, suspended from a eross-head,.j*, and which is carried up by the action of a czun,j, on the central stem or rod f2. vrl'lie eross-hea.d, with the plunger, descends by its own inherent gravity. On being carried through thc box I thepblnnk is creased, and it is carried down by thc plunger a little below the lower creasing edge, when the plunger uscendo again, ready for a new move. -In the menu time the bed L moves up from below to support thc envelope, and the folding fingers turn in one after lthe other, so as tocarry thc 'llups the envelope down to their final position. 'The plunger J carries down a second blank, the lingers K are drawn.' back, und tbc envelope lying on the bed is pressed by the descending plunger. The bell L recedes, the inished envelope drops down, and the second blank which had been carried dou-n by the plunger romains in the lower creasing edge, while the plunger rccedes to admit a new one.l From this description it will he seen the plunger does not ineke any unnecessary motions; on cach descent it creases o blzmlt, and at the same time the finished envelope receives if. final pressing before it is pushed out below. The pressing of the nishcd envelope lo ellected by a crank, lll, which carries a cani, m, that'cctsvupon astud or roller, m*, secured to the central 4stem ,52, which carries the cross-heed und plunger, (see l". 7.) The comv m is adjustable in u, slot in the crunk, so that it can be made to net on the roller m* with more or less `poivrer, according to the desired pressure. The bed L is secured to a. roll, l, which is raised up by the action of u. com, Z*, on the main drivingshaftpund 'the foldingingers'l: nre also moved by the action of cams 7: on the main .lrivingshaft. The cams k arc made to uct on rods lf, :he upper ends of which form toothed racks to gem' in pinions k, on rock-shafts fc3, to which the fingers are secured. Spiral springs securedl to those shafts hold the rods k* down 'upon or in Contact with the cams k. The fingers l :irc provided with hinge-joints, k3, whereby they ore enabled to accommodate themselves more readily to their wow-lc, and to be withdrawn from betvv'een the plunger J, und hed L, without causing any part to hind or to` become injured. It must be remarked thut these lingers are not intended to creasc the blanks before folding, nor to press the flaps after they have been folded. Their function is simply to turn the flaps of the envelopes down after they have been creased by the notion of th plunger und creasing-box, and to hold them in thu-t 'position `until the plunger descends again and gives to the envelopes lthe'fimtl pressing. .In order to give to thocnvelopesthe proper finish, and to press them on those parts where it is particularly needed, the edge ol' the plunger is raised all round on its foce, und',` it is provided with tworibs or ledges, (see (ig, 5,) which are ol' equal height to the outside edge, end which are so situated that they press that portion of the cove-leccate which the pasto has been applied. y ,There are three ythicl'c'ljrcssv,es of paper on that place where the envelope posted, and only two on 'theedges .consequently the l pas*,tseu/is.v pressed more than the edge, and the edge is 'left round and fullns desired. We have new described thef'e'onstruction and operation of one-half of our much-inc; the other hull.' is precisely the sume, and both plungers are attached to the same crossLhoa-ds, so that for cach revolution of the mnin'drivingshsft two envelopes are finished.

what we clcui es new, and desire to secure by Letters Patent, is-

l. The employment cf o movable carrier E, in combination with the rising und falling liftcrs F, constructed and operating in the mnner and for the purpose substantially as herein specified.

2. he arrangement of the table C ovcr'the conveyer H, substimtially in the manner herein described, so time the blanks are held even :md in place by the table while being carried by the conveyor to the creasing-box.
