Y The. machine includes suitable' end ports l0 and ll and a lovver plat-1t which carries electric inotcr l .vh ich power is transmitted by a o a sheave wheel or pulley7 lvvhich inav e called the drive wheel of the machine. "Upon said supporting means the'rnac-hine proper rests and is secured/consisting o side plates 1G and 17, see Fig. 8. which extends longitudinally of the machine for entire length tliereo,'as seen infigs. l and and cross frames 1S, i9 and :20 are seycured between and to said 'side frames 'to make a rigid frame. The cross frame 2G is at the discharge end ot the machine and has an opening 21 through which the envelops discharge. see Fig. l. Atilio extreme righthand end of the machine. as shown in Figs. l' and 3, the crossplate 1S ing onljv7 for a portion of total frame. The side plates i6 and l? are cut anav at their upper right-hand corners, as shown in Fig. 7 so that there is lovver t e. side plate 1G doivn to a level with said lower extension. as seen in Fig. 3. and has slot Q in the lower portion thereof through which the envelops enter 'the mac i There are tivo intermediate 'plates 73 :2% in said traine which extend lon ,nally and horizontally thereof, as shov-'n in lig. l to thele-ft-hand end thereof. that end said upper plate 2l is tspaced lpartici the lower extension of the frame Fig. 6 is a side elevation of :cart

is located extend the height oi the shown in Figs. 2 and, and the. f

are located above and below said 23 and 24,1 as will hereafter be explained At the right-hand end ofthe machine an envelop holder is mounted, consisting of a E. pair of transverse bars 25, see Fig. 3, which are secured to the underside of the inwardly tui-ned flanges of the

side walls

16 and 17 of the machine frame, and longitudinal bars 27,three beingshown in Fig. 1, are secured on said cross bars 25,.as shown in Fig. 3, and on each side of the cross bar 25 said bars 27 are bowed upward, as shown in Fig. 3, and have free projecting ends, although said bars 27 are stitf. There is a pair of ver- 15 ltical rods 28 secured rigidly to arms 29 which are secured to the top of thel side frame 16, as shown in Fig. 1, anda pair of "Yertical rods.30 is secured to arms 31 ad-V justably mounted on a short plate 32 which is secured 'side of -the machine, as appears in Fig. 1. The arms 29 and 3l are arranged so that v'they can be adjusted and, therefore, the povtition of the

rods

28 and 30 canbe adjusted to suit envelops of different. sizes, for the envelops 33, indicated by dotted lines in Fi 3, are placed Ibetween said two pairs of and longitudinally of the machine with* the flaps located on the'side nekt tot e rodsi v30 301 or rear side of the machine', as vie ed'in Fig. 1. One envelop is' shown by dotted p, lines in Fig. 1, after 1t has been started into .l

lvthe machine and that illustrates where the $5 asa pears in Fig. 3, that the lower envelop vt 'ofthe pack will be fed to the left into the guicleway of the machine. "l The means for feeding the lower envelop v from the pack into the machinewis shown in -f A F ig. 3, and consists of a wood roller secured on a shaft 36 and a rubber covering 3701i said roller with a.pair of radial seg- "mental projections 38 thereon. TheseA segmental projections wlien revolved project 4Q up between the lon itudinal bars 27 and into` "'.;,engagemcnt with tie lower envelop so as to feed it from under the igroup lof `envelops finto the -fguideway L,The upper envelopsare prevented from ftlseing fed by 4a fixed bar 40 which is secured if to the end plate 19 and in connection with said fixed b'ar there is a vertical tube 41 iwhich is square in cross section so thats. rubber piece 42 can be inserted and' held `th guideway erein and extend downto the .below to prevent any but the lowest envelop being pressed. The lower end ofthe frubberjpiece 42 is beveled so4 as .to make it '-"sensitive to the action of the envelops.

5.5 fSoon after the envelop enters the guidevay lthrough the vmachine it passes between the pairof feed rol-ls. which grip it and-feed .it on tbi'oi'ghl the guideway. There are two series othese feed rolls, one series 44 above iii* 'and"ne'sc1ies 45 below the guideway. All

guide platesof these feed rolls ma 'the guideway,

through a slot way are mounted at one end in' the sidewall 416 of the frame and cari-yon said ends pinions 52. The other ends of saidvshafts 48 are mounted in arms 53 which extend in-y ward from the inner` surface of the side plate 17 of the main frame as shown in Fig. 7. Therefore,- the lower series of feed rolls 45 are not vertically adjustable. The upper shafts 47 for the upper rollers 44 are mounted so as to be vertically .adjustable, as shown in Fig. 7 that is, they are mounted at one end in a bearing 55 vertically slidable between guides 60 and by a spring 57 adjustably mounted in a lug 58 extending from the inner surfaeeof the frame plate 17. At the'other end said shafts 47 are mounted' inV a similar bearing 55 vertically slidable be vtween guides 60 on the plate 17 and similarly spring controlled. Hence, 'the uper' rolls 444 are spring pressed downwar `on the lower rolls for feeding purposes.

,guideway. The shafts 48 below the guidedriving wheel 15 is mounted on one of the l shafts 48 and power is transmitted from the pinion l52 on the driving oneof the shafts 48 to the pinions-57 on the other shafts 48 by a series of three. intermediate gears 61, 62 and 63. In all of the groups of said wheels61, 62 and 63 they areV arranged in a stri ht' transverseline excepting at the rightnd end where the wheel 62 is .abovel in order to bring the two right-hand shafts 48 closer to ether than any-other pair of hese gcars'l, 62l andy '63 are also a the rig t-hand end and -driven bythe piiiion v52 on the right-hand' shaft v48 andlit transmits ower to a pinion 65 on the shaftI 36 which' eeds theenvelops in the machine. The means for feeding the circulars or letters in the machine and into the envelops is as follows: There is la horizontal side frame secured to-the .outer side ofthe frame plate 17, as shownfin Fig. 7, and extending as shown in Fig. 1, and this side ,framec'onsists ofy a series of brackets orplates 6,7 exf tending transversely away'fromfth'e plate 17 `inal bar 68 secure d to the outer ends thereof.` rllhere'is onebracket or plate 67 opposite each lsetof feed "rolls, see Fig. 1, and between each air of brack' uponithebar '120 for a portion of the length of the machlne,

etter holding' i Iand the inner ends of the arms 170 are turned downward. as shown in Fig. 7. To Ahold the circulars 73, shown by dotted lines in Fig. 7, in place on said frame 70, there 1s on the outer side a pair of vertical arms 7l with the lower ends turned inward and longitudinally and provided with longitudinal Slots 75, see Fig. 7, to which the screws 71 extend so that the posts 7% can be adjusted :and clamped in position. At the end of each lframe 7G there is a U-shaped frame consistling of a lug 7G secured by a screw 'i l' on the bracket T and having a horizontal portion 78 andtwo posts orr fingers T9 which extend upward therefrom, see Figs'rl and 7. The lug' 7G is slotted so that the posts 79 may be adjusted to suit the length of the circulars er letters.

The circulars or letters are fed transrersely ot1 the machine into the machine and envelops by the feeding segments 80 on 'a rubber sleeve 81 surrounding and secured to Wooden rolls 82 which are secured to a ,Shaft 83, as shown in Fig..7, and which is ,mounted in bearings. not shown. secured to -ihe underside of the brackets 67. see Fig. 1, and also in the arms 84 extending'from the -pl'ate 17. Saidshaft 83 is driren by a beveled gear 85 on the shaft 3,6 and gear 86 en the shaft 83. The reason for the seg'- mcntal .arrangement of the envelop feeding .means 38 and the circular feeding means 80 to cause them to feed intermittentlvand at the right time. The envelops do not enter 'in close succession, nor vdo the circulars as they are fed one at a time only when an envelop is in place to receive the circular. Therefore, one envelop and one circular is tied during each revolution of the shaft 3G or 83 and these shafts are geared to the same speed. More than one letter or circular is prevented from beingl fed into the -niechine at a time by raibber lingers or pieces 140, see Fig. 7, which are held in ,guides or holders 141 secured to the outer surface of the frame plate 11T and having a .post 142 projecting upward therefrom. There are two of these pieces of rubber and tricot said posts 'for each holder and said posts coperate with the other posts 74 and 's Q9 in holding the circulars or letters. The

posts 142 are not essential. but flexible means like the rubber finger 110 are essential'for the purposes stated.

'Villien a'circular or letter is fed in through the slot T2, see Fig. 7., its advancing edge asses -b'etw'een lower rubber feed rolls 90 endll. See'Fig. 8, which extend longitudinally of the machine and their meeting edges lie altlileft aboutxone-sixteenth of aninch lower thanthe upper surface of the lower guide plate Q3, see Fig. 8. Said guide plate 223 has its right-hand edge, as shown in Fig.

k8, turned down to form a lip 92 for the entire length.- of the machine, as shown in Figs. 1 and 8. The purpose oi" this will be explained later. The feed rolls and 91 are mounted on a pair of parallel shafts .94 and 95 which extend almost through the machine. rl`he lower shaft 95 is mounted in arms 96 extending inward from the plate 1l. rl`he upper shaft 94 is mounted in bearings 9i' which are vertically slidable in the lower arm of the bracket 56 and which are pressed downward by springs 98 which are i adjustably mounted at their upper 'ends in the arm in said bracket 56, see Fig. 7. T here is any desired number ot' the rolls 90 and 91` there being a pair on each

shaft

94 and 95 opposite each circular or letter bolder, see Fig. 1. The lower shaft 95 is driven by a A beveled gear 99, see the left-hand end of lfig. 1, which meshes with a beveled gear 10() on a stub shaft 101 mounted in thc plate 1T and carryinu a pinion 102 on its -outer end which meshes Vith a pinion 103 on a shaft 101 extending through the machine, see Figs. -land (i, and carrying on its other end a pinion 105 which engages. a gear 10G on the left-hand shaft 48. The stub anlc 101, see Fig. 4, is held in place by an arm 108 secured to the plate 17. As the envelop enters the guideway through the machine and moves to the dotted line position shown in Fig. 1, the flap of the envelop is opened by a plate 110 which is 'seen in Fig. 1. l'he plate 110 ,is integral with or secured'to the top guide plate E24 and it is spirally disposed 4 or inthe form of a plow share or flange of `corner of Fig. 1, is made of spring metal.

and projects to the right-hand end of the plate 110 and is at that point sprung up somewhat higher than said end of plate 110 so as to bc sure to hold the llap ot' the envolop high enough to insureit passing above the left-hand end ot' plate 110 instead of below it. As the envelop goes through the machine, the flap is held down .in its open position by a bar 111 which extends longitudinally ot' the machine/just below the inner edges of the lower series of feed rolls 91 and is held in place by arms 112 secured to the inner surface' ol said frame plate 17, as shown in Figs. 7 and 8. This leaves the mouth of the envelop open to receive acir-A cular or letter. As the em'elopr isfed on through the machine after the flap has kbeen opened by the camplate 110, it vis'sto'pped temporarily in frontof the first .circular or letter holder. The meansor stopping. the

envelop in such position :so a'kto receive-o uit" circular or letter consists of two stops 115 projecting downward through openings 116 1n the top guide plate`24, see Fig, 1. These stops project through the guideway 1n the 5 path 'of the envelop and they are divergent arms of a lever formed of a slotted hollow portionl117 and another portion 118 pro jecting into ,the hollow portion and held in .adjusted position by a set screw 119, where- 1'0 vby the length of the lever and the position of the stops can be predetermined. The lever is rigidly secured on a shaft 120 mounted in bearings 121 extending up from the guide plate 24 and on said shalt 120 there is an arm 1'22 rigidly secured, the freeend of' which rides upon a -cam 123 mounted on a shaft 124, which extends transversely through the machine and has bearings in the

side vframe plates

16 and 17 and is driven 20 from the gearing heretofore described and shown in Fig. 2, through wheels 125. There is one of these shafts 124 opposite the middle portion of each holder for circulars and envelops. The cam 123 is illustrated bijll 2'5 dotted lines in Fig. 9, and it is formed wit one cam projection adapted by acting on the arm. 122 to raise the stops 115 and permit the hnvelop to be'moved on its way, but during nearly the whole rotation of the i shaft124 the stops 115 arev down in position to stop an envelop, ashowninFig. 9. The Fenvelop is stoppech et'ween pairsof .feed

vrolls 44 and 45.and,out of engagement with them.` While .the .envelop is held for its vperiodof time, `a. circular or letteris fed laterally by `the \means heretofore described and shoved' into the envelop. At that timethere is nothing pressing downy on the en-4 velop and the flap is held turned downward 4() ajs'heretofore explained, so that` the mouth ofthe envelop gaps and permits a circular vorjlet'tr to enterthe envelop. Of course, y for rapid `operation the letter or circular v .should'jbe/small enough' to readilyenter the 45 envelop without catching on the ends thereof.. ,After the circular or letter has entered the envelopit is necessary that the envelop 'be'.,fed-to 'the next set of feed rolls 44 and 45.'

This is doneby a rubber cam-like projection :91% thev feed rollsv 131 secured on the shats .124'and 1,32.- v'l.`lie'lattcr shaftsl132 ',arelolc'ated'below the guideway and mountedgy-transversely of the machine in the side" fraline'plates 1G and, 17 and are driven by ;.'lall Iofhtliefzgears 62 heretofore described ex- L,yospiti-ing;,the one near the righthand end of'v Uthe lil-indusse Figs. 1 and 2.` These .projectidgnspill() from the feeding rolls 131 op- Icratethrough-openings 134 in the guideway `

effect .ny'rfrictidpalengagement with the Ienve'lop "'andfeed 1t to the next feed rolls 44 and 45 vThis operation can berepeatedfor any desired number of holders, frm one up. As here shown only two such holders appear, but in the machine heretofore built by me there are four such holders for circulars and 79 letters so that with such machine, four different kinds ofcirculars or letters can be inserted in the sameenvelop and cards can `be inserted in the envelops as well as flexible circulars and. letters. Of course, when circulars and letters are to be inserted in envelo s, they 'must be folded-before they are put inthe holders -and preferably folded so that each one will be as compact as possible so as to ,be stiff enough to feed straight into 8o the envelop. Thep'rojection' on thev cam 123 extends in a direction opposite to the projection 130 on the feed rolls'181, as shown inV Eig. 9, and they are vso arranged that the cam 123 will lift'the stops 115 just before 85 the projection' 130 cornesy into feeding en- {gagement with the envelop and, as is obvious from the drawingthe cam 123 permits the stop soon, however, to drop, but it merely rides on the envelop without interfering with its feeding'movement. The vmachine operates at rather considerable speed so that the envelop is fed rather rapidly and as it plish their feeding in advance'of'the projections on the other rolls referred to and afterthe feeding projections for the circulars'have' done their worin-'then the feeding projections on the other rolls engage the envelops andstart them throughtlie regular feeding

rollsY

44 and 45. The means forl feeding the envelops from the envelop holder, the means for feedingthe circulars and letters from the circular holder, and the 'meansQfor starting the, envelops afterthe circulars have been putin them,` all are geared to operate'at the same speed,` and their rotation is coterminous. The feed" 12o j rolls 44 and 45 and also the `littlefeed rolls .90 and `911`operate continuously and in fact all of the feed rolls operate oo inuosly, but those for feeding the envelope and circulars from their holders and foi starting: the envelops afterfthe vcirculars are in them, have projections which meet only for ashort portion ofthe revolution of the ,feed rolls on which-they are located. and, therefore, these feed rolls act intermittentlyl while the-feed A i "w 'will maniere i rolls se and 45, and 90 and 9i operate so neto act at any time if there'is an envelop or circular in position to be acted/ upon by them.

To enable the machine to operate satisfactorily on envelope of varying widths, the pests 28, see the right-hand end of Fig. l, can be adjusted toward or away from the other posts 30 by altering the position of the arms 29. There is also a guide 150 secured onthe inside of the frame plate 16 for guidin the edges of the envelops after they have le t the posts 28 and until they get into the guideway of the machine, and this plate 150 is adjusted by set screws ll. For varying 'lengths of envelops the onlyv adjustment required is that of the lever elements l1? and 118 so as to change the position of the stops 115 and enable them to stop the envelops at the right `positions beside the circular holders.
