To @Z5 iff-imm, it may erinnern.:

Be it known that I MILTON C. Ellison, e citizen of thelinited States, residing et St. Paul, in the county of Ramsey and State of Minnesota, have invented certein new and useful Improvements in Filled-SackSe\sfing Machines and I do hereby declare the following to be a. full, clear, and exact description oi the invention, such es will enable others skilled in the art to which it apportnins to ineke and use the seme.

My present invention relates to Whet are known es iilled-seck-sewing machines, and has for its object to improve the seine in the several particulars hereinafter noted.

The invention consists of the novel devises end combinations of devices hereinafter described, sind defined in the claims.

This invention is designed especially as an improvement on the niechine set forth end claimed in iny Letters Patent No. 773,631 issued oi date November 1, 1904, entitled l*"illed-l3egsewing machine.

in the accompanying drawings, Which illus! trete rey invention, like characters indioete like ports throughout the several views.

Figure 1 shows the complete sewing-mechine in side elevation. Fig. 2 is e transverse vertical section on the line x2 x* ol Fig. i.V Fig. 3 is a. detail in transverse vertieel seotion epproxiinateiyon the line x3 x73 of Fig. 4. 4 is n horizontal section on the line :r4 m4 of l*s ig. 2. Fig. 5 is e detail approximately on the line r :c5 of Fig. 3. Fi 6 is a. horizontal seetion on the line of i 2, some arts Fig. 7 is e orizonta section nteken approximately on the line mi m7 of Fig. 2, Sonie parte being broken away; and Fig. 8 is a detail in pien illustrating the nienner in which the needle-holder is ivotelly etteehed to the needle-operating pinger, some parte being broken away.

The freine of the machine is, es shown, inode up of a box-like housing 1` which is rigidly sup orted in any suitable wey and is providedp at one side with en outwardly and downwardly turned hollow supportingbracket 2, having at" itsV depending end a transversely-elongated bearing-heed 3, in

which is mounted a reciprocating needle-serYV Y rying plunger 4. Mounted in suitable been ings within the freine or easing 1 is e vertically-disposed counter-shaft 5, which at its upwardly-projecting end above seid easing is provided with o initer-gear 6 and e hendwheel 7. The initer-geer 6 meshes with e reiter-gear 8, the hub of which is loosely journeled in e hearing on the upper ortion of the freine 1 end is provided wit i e heli'- eluteh 10. A driving-'shaft 11 is -ournnled in the hub of the gear 8 and in ot er suitable bearings. (Not shown.) On the shaft 1 1 is e sliding lialelotch 12, which cooperates with the half-clutch 10, being held to rotate with seid shaft by e key 1.3i The sliding helfoluteh 12 is subject to o shipper-lover '14, Whieh lever, Yes shown, is pivoted et one end to e. lug 15 end is edn. ted to be looked et its free end to e lug 16 y ineens of a. springlstoh 1PZ. The tivo lugs 15 and 16 are shown es esst integral with the casing 1. The coun'- ter-sheft 5 carries two peripheral @eine 1S end 19 sind s. Worin 20, the purposes of which will presently ap ear. At its extreme lower end the shaft 5 is provided with e short throwerenli 21, the crank-pin of which Works in e longitudinal slot 22 of en oscillating loop or bar 23, which loop or ber is, es shown, pivoted et one end to e lug 24 on the interior of the lensing 1, as best shown in Figs. 1, 2, and Ei'. rl`he loop or ber 23 oseille-tes in e horizontel piene and, es shown, carries e supplementel pivotally-attaohed bei' (more fully shown in my seid Letters Patent le. 173,631, of date November 1, 1904,) Vwhich et its Yfree i endnis provided with a depending foot 26, in "which is secured the laterally bent shank of a loo er 27. (See Figs. 2 3, end 6.) The free enY Y Qftheloop oriier' rests upon sind vibretesever e restlate 24a.

The thread whic passes through the looper 27 on its wey from the spool to said loo or passes between the clamping-disks 28 o e tension device 2Q; which tension device is, as shown, supported by a. lug 30 on the eosin i' I. This tension device may be of any suite le construction, het is shown end preferred in States Pet-ent No. ''gliili ofdeteetoberi 1 g, i904, entitled Thread and twine tension device. Furthermore, the thread on its wey to the loo Ver 27 posses through an eye 3l in the free end) of en oscillating sleek-erm 32, which, es shown,is l.riveted to e. bearing 33 Within the easing i' en is subject to the com i9, carried hy the slieft. Y

The needle 34 is direetlyseoured, es shown, by ineens of e set-screw 85 to a heed 36, which in turn is pivoted et 37 to the forward end oi' the needle-carrying plunger 4, as best shown in Figs. 2, 3, 4, and 8. The needle heed or holder 36 is adapted to be pivotelly turned the form set' forth and claimed in my United' IOO upward into a vertical position, as shown by dotted lines in Fig. 3, thereby throwing the needle into a position in which it may be easily threaded. This feature is therefore important. The downward pivotal movement of the head 36 is limited to a straight line with the plunger 4 by cooperating stop-shoulders 36 on the said head and plunger. The plun- Urer 4 at its extreme forward end and at its lower portion is formed with a lip 4, which underlies the free end ofthe head 36,0perates as a stop therefor, and prevents the thread from sagging or dropping down too low when the machine is in action, (see Figs. 2 and 3,) at which time the needle is turned. down, as best shown in said Fig. To lock the head or holder 36 in an operative position, a springlatch 38 is secured at the forward end to the plunger 4 and at its free end is provided with a lock-lip 38, that normally overlies the free end ot said head 36. The numeral 39 indicates a guard-clip on the forward end of the 11eedle-plunger 4, which ovcrlics the springd latch 38. In the plunger 4, just at the rear of the rear end ofthe head 3G, is a vertical thread-guiding perforation or passage 4t), through which the thread is passed. (See Figs. 2, 3, and 8.)

The thread which. passes through the eye of the needle 34 is indicated by the dotted lines marked z. This thread, as shown, )asses through guide-eyes 4l on the supportlng-bracket 2 and between the clampingdisks 28 of a tension. device 2Q, shown as supported by a lug 30 on the head 3 ot the bearing-bracket 2. This tension device is preferably of the.` same character as the one previously described and designated by the numerals 28 29. Then the head 3G and the needle 34 are in operative `iositions, they are below the upper plate of the hollow bearinghead 3, and to permit the said parts to be moved pivotally upward a small hinged plate or trap-door 42 is provided. in the upper wall of said bearing-head 3, just above the said needle and itsiholder. Under its outward movement the needle 34 works through a erforation 43 ol a work-guiding flange 44, w lich flange, as shown, is cast integral with a plate 45. The plate 45 spaced apart from a lower plate 46 by spacing-thimbles 47 and the said two plates are rigidly connsfeted to and supported from the lower plate of the casing l by nutted bolts 4S, passed through said three plates and said thimbles. (See Figs. 2, 3, and The needle-plunger 4 receives its reciprocating movements through a bell-crank lever 4Q, the elbow of which'is pivoted at 5() to the bearing-braclwt 2 and one arm ot which is provided with a rollerequipped stud 51, that works in the groove ot' the cam 18. .The depending end of the bellcrank 4), as shown, works between a pair of studs 52 on the needle-plunger 4.

The gathered ends ol' the filled sacks are ,Figs 3 and 4.

'fed to the stitching mechanism by a feedchain, presently to be described, and they are caused to travel through a straight and very narrow guide-channel formed between. the guide flange or plate 44 and an opposing yielding presser-bar made up of a plurality of sections or blocks 53, located with their ends in close contact and mounted in suitable seats formed in a bar 3, which bar is mounted in the inner edge of the hollow bearing -head 3. (See particularly Figs. 2, 3, 4, and 5.,) rFliese sections 53 are Jformed with stop-lugs 54, (see Figs 3 and 4,) which engage with the bar 3 tolimit their outward movements. The bar 3 is, as shown, formed in two parts, said parts being rigidly united by screws 3l. The sections 53 are yieldingly )resscd outward by curved springs 55, which are seated at one end in the bar 3 and at their outer ends )ress against the said. sections and overlap the joints bctween the same, as best shown in Fig. 5. Each section 53 is provided with a pin 53, so positioned as to be engaged by the free end of the spring 55. As each section of the chain is pressed inward against the spring by the travel. of the sack the free end of said spring will engage the pin in the next adjacent section, thereby moving said section inward, so that the chain will always )resent a smooth surface to the sack. The )ar 3 is ada ted to be adjusted transversely of the guirlh-channel formed between the guidev(lange 44 and. the yielding bar made up of the sections 53 under the action ot screws 56, which work through and are clamped to bearings 57 on the lower plate of the bcaring-hezul 3 by means of lock-nuts 58. At its central portion the bar 3 is eut away to alford elearance lor the needle 34 and the end of the needie-plunger 4, as best shown in Fig. 4, and one of the sections 53 is perforated at 53 (see Fig. 3) to ali'ord a passage for the needle 34.

The gathered ends of the filled sack are fed to the stitching mechanism and through the shallow guidechannel already noted by vn'leans of endless feed-chains 59, to the links of which are secured serrated feed-clips 6U. This chain runs over three sprockets 61 (i2, and 63, and it is passed between the plates 45 and 46, heretofore noted, as clearly shown in Figs. and 3. The feed-cli )s `)reject at their serrated. edges into the guidIc-c iannel formed between the guide-Bange 44 and the yielding sectional presser-bar 53, as best shown in i That portion of the chain which is running from the sprocket 62 to the sprocket G1 bears at its back against a guidebar 64, which works between the plates 45 and 46 and is adapted to be adjusted trans versely of the chain by screws 65, swiveled thereto and working through bearingblocks GG on the lower plate ol' the casing] and locked to said blocks by nuts 67. Said bar 64 is provided with transverse slots 64, through IOO ruiter-gear 70, that meshes With e ruiter-gear .Y

Y l oi' a short horizontally-disposed she'it T2,

(see Figs. 4 and 7,) which shaft has ay large worin-getti' 73, that meshes With the Worin 20 on the vertical shaft 5. In this vvaiT motion is iniperted from the driving-shaft 1i to the vertie el shaft- 5 and from thence throught-he connections just desoribed to the feed-chain 59, The sprocket 62 is ioosely journeled on the lower late of the easing 1. The s rocket 63 ioose y ourneled in en edjustab e beering Whieh, as shown, has a threaded stern El-ta, (see Figs. 2 and 4,) that Works through e. fixed bearing on the bese-Harige of the eesing 1 end is locked thereto by nut-s 7 5a. By adjustments of the sprocket 63 the sleek of the chain 59 may be teken up.

The gathering device, which is very similar to that set forth sind claimed in my seid Let# terel Patent No. 7 7 3,631, of date November 1, 1904, but Which involves novel features of improvement, is constructed as follows: A pair of vertically-disposed shafts 76 and 7 7 ere mounted the former in internel bearings on the casing 1 and the latter in bearings within the vertical portion of the bearingbreoket 2. At their upper ends these shafts ere provided with reiter-gears 7 S, (see Figs. 2 and 7 that mesh with ruiter-gears 79 on e horizontal counter-shaft 80, mounted in suitable bearings on the easing 1 and bearing-bracket 2. One end of the shaft 8() projects through the easing l and is rovided with spur-gear 81, that meshes Wit e spurpinion 82, Carried by the driving-shaft 1l. At their extreme lower ends the vertical shafts 76 end 77 are rovided with shortthrow eeoontrios S3. (i ee Figs. 2, 4, and {5.} These .entries operate ou the ends of soeeef gethering-pewls S, which pewls et their intermediate portions are slotted at and are ulorurned on pins 86, carried by fuleruin-bloeks S7, which hiloruni-l'ilooks, as shown, have threaded stems 8S, that Work through bearings S9 on the lower iienge of the bearing-heed 3 and are clamped thereto by nuts 83a. The gatherin pewls 84 are provided with suppementa spring-extensions U0, which at their free ends Gerry gathering-heads 91. The spring-sections 99 are adjustebly secured to the bodies of the pewls 84 b v set-screws 92, and eeeh pewl is provided with e tooth 93, thet engages With teeth or serretions 94 on the corresponding peWl 84. The set-screws 92 Work through slots 95 in the said s ring-seotions 90 and ere screwed into the en s of the pewls 84. As is evident, under the rotary movements of the eceentries rotary movements will be imparted to the ends of the gathering-heads Qi, end the two heads Will act simultaneously to gather the mouth of the seek and to feed the seine into the guide-channel bet-Ween the W,Quide-tlenge '14 and yielding ber where the seme will be taken up end eeted upon by Vthe".serreted clips of the feed-(drinn.V hinder the shove gathering action the seo- Ytions 9D of the athering-psiris yieidingiy ress the engaged portion of the seek, the ongitudinal adjustments of the spring-sec tions 91 on the psud-bodies The pewlheads 91 may be set for eetio i on the Work et the proper points, end by shifting the fuleruni-bloeks 87 the are of operative movementof the seid heeds 91 may be changed so as to vary the amount of gather Whirh Will be given to the mouth of the seek. When the gathered portion of the seek is fed through the guide-channel by the serrated clips of the feed-chain, theseotions of the yielding presser'- bar 53 Will yield to adept themselves to the varying thielrness et the gathered mouth of the sack, end it is importent to note that this yielding action does not move laterally the i feed-chain, end hence does not decrease or vary the bite which the serrated edges of the clips normally have upon the gethered portion of the'seok. Otherwise stated, the serrated edges el' the feed-clips elwaLxv's have a inexiinuni bite on the seek, Which is due to the fast that the presser-bar instead of the feed-oheinis mounted to yield. The pressure under which the yielding sectioned presserbar 53 will engage the sack muy be varied by adjustments of the bearing-ber 3a, end the normal projection of the serrated edges of the eed=elips of the feed-chain into the guideehennel iney be varied by adjustments of the ber 64.

It xviii et course be understood that the mechanism ebove described is eepshle of merry modifications Within the. seope of my invention es herein sot forth and eieinied.
