Beit known that I, JUL'IUs BRENZING'ER,

-a citizen of the United States, residing at Mount Vernon, Westchester county, State of y New York, have invented new and use v"linrovements in Machineslfor Lining Covers or Cansvand Jars, specification.

A This invention relates. to a machine forf' ro placing a lining or liquid packing into the e groove of a cover for cans and jars', such lin- Y Ing subsequentlyserving to form an air-tightK joint between cover andcan.

The machine is so constructed that itwill simultaneously line a large number of covers,

'so that acorrespondingl large output is insured. Briely stated, the machineis composed of a rotatable table carrying a number of glue-delivery nozzles. The covers are sucL 2o cessively -placed upon the table and held thereto beneath the nozzles by means which also rotate the covers around their own axes. Thus as the table is rotated the covers will successively be lined to be finally discharged from achute.

In the accompan g drawings,`Fig1p1re is a front view, part 1n section, of my improved 4machine for ining covers for cans and jars; Fig. 2, a lan thereof; Fig. 3, a horiz-om 3o 'tal section on lne 3 3, Fig. 1, with lsome of the arts omitted; Fig. 4, a detail front view of t e cover holding and lining mechanism;

v Fig. 5,' a side view, artly in, section, thereof, showing a cover in p ace Fig. 6, a plan ofthe v cover-holding mechanism, and Fig. 7 a longitudinal section through the lining-cylinder.

The letter 'a indicates'the frame of the machine, in which al vertical shaft b is rotatably mounted. 4.Sha't 4I) receives motion from a 4o power-shaft, c by belt c', counter-shaft c2, ear-wheelscSi c, shaft c5, and ear-wheels cG l To shaftb 1s secured a ta le b2, that in y turn lsupports a pot (Z, containin f the glue orv .other lining. T is' lining is .supplied from the pot simultaneously to al suitable number of lcovers A, the drawings showing a machine adapted for the "simultaneous treatment of six covers. The glue contained in pot d may be agitated by a suitable stirrer (not shown) 5o attached to a spindle d, that receives motion by an endless rope d. In order 4to insure a proper discharge ofthe glue through the no'z' ales hereinafter described, the glue is kept unof which the following is a i 'ner hereinafter der a certain pressure by a pressure-pipe d?, .entering ot d and havinv cock d4. This pipe supplies the pot d with compressed an' or other pressure medium from a 'suitable pressure-tank. (Not shown.) The pot d is provided with a serres of hollow plu s d5, each of which 'communicates by a pipev with a separat-e cylinder e, secured topot d by bracket d. Each cylinder e is provided with a' discharge-nozzle e', the disl charge-opening ot'4 which is controlled by a vertically-reciprocating plunger, e2. In order to prevent any clogging of thea nozzle, the plunger e3 isl rovided with alneedle e3, that passes throng the reduced bore oi the` dis.

charge-o ening when the to close t e nozzle. .y

The plunger e2 is o erated in the following manner: Each cylin er.'e is provlded w1th an upright c, having-a horizontal arm e5, through an opening of which the upper endv of plunger e2 passes. To'plunger ,e2 1s clamped a crosspiece c", having a pin e7, whlch. 1s guided Withln a corresponding .openlng of arm e5. A spring es intermediate cross-piece c and arm e5 tends to hold plunger e2 in Its lowerniost or closed position. To cross-piece e.1s plvoted at e9 a two-arm lever f, one end of Whlchcarplunger -is lowered ries a rolllerf,while its other end is provided l i and i 4 sctsjr2 constitute a fulcrum for lever f, so

that when roller is raised by a cam in manescr'bed the l also be raised a` ainsi the action o springes to open nozzle e When, on the-otherl hand, roller f is out -of engagement with sald cam, s ring e"v will tilt lever f vdownward to lower p unger e2 and close nozzle e. .l I i The cam; hereinabove referred .to consists of anumber of curved' cam-sections g', removably mounted upon aiixedrall g, which, is secured tovrame aby brackets c. The rollers j" areadapted to ride upon the cam- 'sections g so as to raise lever f and open noz zles e. By removing one or more o f the cam-,sections the Working lengthof the cam .is correspondingly changed to regulatethe timeduringwhich -the -glue is supplied to covers A. The -.cover' "A, which'may be of 4 square, oblong, round, or other shape, is pro-l plunger ev2 `will y IOO frictionally en aged by the roughened edge of afeed-disk fast ona rotatin and vertically-reciprocating s indle h. `he number of disks h correspon s to the number of nozzles and covers 'to 'be simultaneously lined. Each spindle h is mounted in a guide or support i, secured to table b2, vand in a bracket c, depending `from such guide. In this way disks h and spindles h will be revolved by table b2 while theyjreceive an independent rotatory movement in the following manner: The lower end of each spindle h is (provided with a pinion h2, engaging a toothe wheel j, loosely mounted upon shaft b. To the hub j of wheel j is secured a toothedwheel jZ, that meshes into a gear-wheel c7, fast on shaft c5. While the inner flange A2 is-enga ed by disk h, the cuter ilange A3 of groove A is adapted to be en aged by a'pair of counter-rollers 7c 7c, mounted upon a slide 1c Figs. 5 and 6. The latter is movable within a corresponding way o'f'guide i. Aspring k2 is suspended between a pair of lugs i 7c3 of guide 'i and slide lc', res ectively, and tends to draw rollers lc toward isk h. It will thus be seen that when the grooved-edge of a cover A is inter osed be tween the rotating disk 7i and rol ers 7c thev groove A will travel around disk h for its entire length at each rotation of the cover. yThe nozzle e is arranged laterally beyond'the disk h and midway between rollers 7c above the point marked Xin Fig. 6. The distance between this loint and the disk h should be such that 'elle nozzle is .centered above the groove A. y An up er guard Z prevents the cover from being isplaced vertically while being rotated.

In order to permit lthe insertion of an unlined cover and the removal of the lined cover, disks h, as Well as rollers lo, are made displaceable in the' following manner: Each dis is "free to enter a corres ending recess 'i3 of guide "i 'when spindle h is lowered. To lower the spindle, the hub of pinion h2 is rovided with a collar h3, having pins h4, w ich engage perforations m' of a shippin -lever m. The latter is pivoted'at ni2 to a s i er n, fast on and rotating with shaft b. "he free end of lever m is provided with a roller m3, ada 'tcd to engage the lower side of a curved rai or f arc-sha ed cam o, secured to frame a. A

spring 5, interposed between bracket i and a `collar h6 of spindle h tendsto raise the latter, so that pinion h is normally proj ectedjbe- For this pur ose.

yond the upper face di guide e', 'Fig'. 5. When roller mB is engaged by cam o, shipping-lever mi-'Will ibe Elowered to correspondingly lower Yspindle h and pinion h. In this lowered position vpinion h is. countersunk by being received by recess t3, so that the to of disk 7L is iiush withthe face of. guide e. hile disk 7L is lowered its coperating rollers k are pushed away from the disk in 'the yfollowing manner: From each slide k depends a pin lc, carrying a ro'ller c, adapted to engage a curved rail or arc-shaped cam p, secured to frame a. When the -roler'ksengages rail.I slide' c is pushed toward the ycenter `of t e .machina so that rollers 7c are AmovedA way from -disk h. As will be seen ffroin Fig. '8, cams o and p lare s arranged relativdlyto each other that they arev enga edahout simiile taneously by rdllersj'n'i3 and s, respectively. In this way the diskh'is lowered while the rollers lc are moved inward, so thatthe coverflanges A2 A3 are simultaneously liberated. The lined covers A aredis'charged iii-0in the machine by a 'fixed deiiector ,that'conveys them to an iiiclineddeliverym rute g. In order to prevent the `plunger 'e2 from opening nozzle e when'a cover is notinserted lintollhe holding device, there is attachedto slide'lca'n arm 7c, which is adapted Vtelen age with its upper horizontal shank k7 the uwer end'fo' lever f3, Fig. 5. Arm le `is so shaped lthat when a cover is introduced *between ldisk-'i1 and rollers lc "leverf3 `will 'not be'engaged lb T shank k7; but if a Icover is not 'inserte spring k2 will draw slide lc" out-ward, so that shank k7 engages leverfaand itilts lthe same in such a manner that its offset jf* willolear oisetf2 of lever f. lflrcllerf is iiewrased by engaging cam-pieces g,lever f will loosely turn onpivot e withoutliitingphinger'e so that nozzle e remains closed.

The operation is as follows: Talile-'b'2,ito gether with nozzles e and guides 'f, =is sloavlar rotated in the directioirdf arrow B,.'Fig. 2, by the train of gears above described, and'iis'ks h are simultaneously rotated by the engagement of pinions h2 and toothed wheel j.
