and i Fig. 9 is a view corresponding to Fig. 2 but showing the parts as positioned in Fig..8.

While the present invention is shown applied to a commercial bottleV filling machine in place of its twin bottle capping head, it will be understood that the same may be designed as an in` upper end of the shaft 11.

held against endwise movement in the bearing 21= by a collar 22below said bearing bracket, and

and pair of lfixed upright guide posts 12. These guide posts 12 extend upward through the feed table 10 andare connected thereabove by upper and

lower tie'members

13 and 14, respectively. The upper tie member 13 is vertically adjustable onthe guide posts 112, for a purposethat will hereinafter appear, and rigidly .secured where adjusted on said posts by hand-screws which have threaded engagement with thetiefmember` 13 and impinge against the guide posts l2. The

table 10 and is rigidly secured to the guide posts 12 by split clamping `collars 16 formed with said.:

tie member. The shaft 11,V which is `midwaybetween the two guide postsl `12 and parallel there-,-V g to, is mounted for endwise reciprocatory movement in bearings formed with the

tie members

13 and 14. For the purpose `of vthiscase .it is lower tiemember 14 rests on the top of the feed not thought necessary to illustrate the' driving Y connections for reciprocating the shaft 11.

A cross-head 17 is 'slidably mounted on the'4 guide posts l2 vand. has a recessed seat V18 for a twingcapping head, not shown, secured by' a pair. of nut-equipped bolts 19 to said cross-head. ThisV cross-head 17 is connected to the shaft 11 for relative longitudinal adjustment by a long screw- Y' rod 20 which has threaded engagementwith'said cross-head.` The upper end of the screw-rod' 20 .l

is turnably mounted in a bearing 21 fixed .on the Said screw-rod 20 is the hubV of aA hand-crank`23V above said `bearing bracket and bywhich' hand-crank the screw-rod the hand-crank 23 are ,secured by pins to ,the`-`V` screW-rod' 20. By operating the screw-rod 20 the capping lhead may be raised or lowered and the cross-tie member 13 adjusted on the guide for instance,

of thiscase, it will not be' necessary to illustrate. f

From a broad view point the bottles X may be placed on the feed table 10 in bottle capping positions by hand or otherwise.

Referring n'owin detail to the invention which includes twin capping heads that are laterally spaced from eachother and each thereof includes a base 24 on which a blockk25 issecured by screws. 4The ltwin capping heads are individually and detachably'secured to the'cross-head 17 by having formed therewith bearing brackets 26 mounted in the cross-head seat 18 and rigidly secured by the bolts 19 to the cross-head 17. These bolts 19 extend through horizontal slots [51 in the bearing brackets 26 which permit common horizontal adjustment of the twin capping heads on the cross-head 17. A long'tie-bolt .27, which f extends:throughv apertured lugs ionthe bear-ing brackets 26, -clamps said bearing brackets together and prevents lateral separationu thereof.

Formed in each block 25 is an Youter cylindrical magazine 28, a center or intermediatedie a stop that limits the lifting movement of the cylinder 29, and an inner cap-apply-ing'lcylinderi :the'idie'ring 39 center the blanks Y as they are 30. The axes of the magazine28 and the two

Y

The upper` die'38 is in thegform Voi a `plunger mounted .in thediecylinder 29. i or reciprocatory .movement and comprises an outer sleeve 44 "and central .core`45 which have a limited'relative axial sliding movement. Said...die .core 45A normally extends completely thrc'ughthe sleeve 44 .and arranged to. enter. the ring 39, .depresstheY l.la-tion." `The purposeof this loose connection be- #tween the die 'sleeve 44 and '.die core' i45 is'to cause the die sleeve 44 to move downwardwith rthe die-core 45 andA permit an' initialreturn 'or upward movementiof.. said core in respect to the -die sleeve 44 and cause. said core to act asV astripper to remove aformed cap' Z from the die38. .During the return movement of the .die `33 :the

'asndateof"itsrends; San inter-'nal' annular-Stop ledge 53. The walls of? the passageway 52 from the outer edgeof the stop ledge 53 diverge outwardlyand downwardly 'and afford a bottle centering surface 54. The passageway 52, above the stop ledge 53, is of the same diameter as `the cap-applying cylinder 30. 1

Within the cap-applying cylinder 30 is a reciprocatory bottle-aligning and clamping sleeve 55 held against rotation in said cylinder by a key and keyway 56. The sleeve 55 normally rests on the stop ledge 53 "and is yieldingly held by a coiled spring 57 compressed between the top of the sleeve 55 and a screw-cap 58 which closes the upper end ofthe cylinder 30. In the lower end of the sleeve 55l is an internal bottle-aligning and holding seat 59 arranged to receive the outer top portion of a bottle and align the same with said sleeve and hold the bottle against lateral movement in respect thereto.

Withinthe sleeve 55 is a'reciprocatory plunger 60 having at its axis an upwardly projecting stem 6l which works in -a seat therefore inthe cap 58. A coiled spring 62, encircling the stem 61, is compressed between the cap 58 and plunger 60, normally and yieldingly holds said plunger projected.l A nut 63 applied to the stem 61 outward of the cap 58 is arranged to engage said `cap as a base of resistance and limit the projecting movement of the plunger 60. The lower end portion of the plunger 60 is shaped to'enter the depressed central portion of the cap Z and engage the entire upper surface of the cap and press the same into the neck of a bottle on the seat therefore in said neck and also press its sanitary flange onto the top of a bottle.

The caps Zas they are formed and stripped from the dies 37 and 38 are successively moved edgewise from theV cap-forming cylinder 29 through a passageway 64"in the wall of the block 25 between the cylinders 29 vand 30, through a passageway 65 in the sleeve 55 and into said sleeve. When the sleeve 55 is resting on the stop shoulder 53` its passageway 65 is in nal diameter same as the of the sleeve 55 is substantially the external diameter of the sanitary fiange of the'cap vZ and the engagement of said flange with the internal wall of the sleeve 55 centers the cap in said sleeve and in respect to the bottle X.

An ejector bar 66 is cap Z from the cap-forming cylinder 29 to the ycap-applying cylinderv 30. This ejector bar 66 extendstransversely over .the base 24 and'slidably rests thereon `for reciprocatory movement. The under side of the ejector. bar65 intermex4 diate of its endsis provided with a notch ofv such size as to permit said bar to pass'over the posi'- tioning pins 43. This ejectorbar 66 above its notch is arranged to engage a cap Z at the edge of its sanitary flange and move the same in ad- Vance thereof. l

Referring nowto the connections for reciprocating the ejector slide 33, the same'includes a pair of bell-cranks 67 pivoted at their elbows to a pair of brackets 68 secured one to each side ofthe block 25. bell-cranks 67 extend vertically downward, are relativelylong and connected by a pair of horizontal links 69 to the sides of the cross-head The other arms of thebell-cranks 67 are very short, extend horizontally away fromthe ejector slide 33, are bifurcated and have formed on the upper prongs thereof, substantially verti- `,cal cam 4surfaces 70 and on the lower prongs provided forfmoving theV manner.

The depending arms of` theA thereof substantially horizontal cam surfaces 71,. Cooperating with each pair of cam surifaces .70 and 71 is a cam roller 72. The two cam` rollers 72 are journaled on a pair of axially aligned trunnions on the -lower end portions of the legs of a yoke 73 that transversely straddles the block 25. This yoke 73 is carried by the stem 61 which extends through a bore at the center of the transverse portion of said yoke.

A nut 74 applied to the stern 61 ,outward of the yoke 73 is arranged to engage said yoke and limit the upward movement of the yoke thereon. The stem 61 above the nut 63 is reduced .in diameter to form a shoulder 75v and a coiled spring 76 encircling the stem 61 is compressed between said shoulder and the under side of the transverse portion of the yoke 73.. The purpose of the spring 76 is to cushion the action between the cam rollers 72 and the bell-cranks f 67. The legs of the reciprocatoryyoke 73 are held by anti-friction guide rollers 77 against the action of the cam rollers 72 on the cam the brackets 68 may beradjusted on the block 100 25 toward or from the guide rollers 77. Ob-

viously, thevengagement of the cam rollers 72 with the cam surfaces 70 and` 71 oscillates the bell-cranks 67 which, in turnpreciprocate the ejector slide 33. l

The die 38 is reciprocated` by the following connections, actuated by the capping head during its reciprocatory movement by the shaft 80. A vertical link A81-ispivoted at its upper v v l end to and between the'levers 78 for horizontal ahgnment with the passageway 64.Y The 1nterswinging movement parallel to saidzlevers and its lower end ispivoted to a short heavy stem 82 on the die core 45. This stemV 82 has on its lower end a screw stud 83 which is screwed into the top,v of the die core 45 at the axis thereof to connect the same. i

The'ejector bar 66 is reciprocated from the connectionswhich reciprocate the die 38 by'a pair of cam rollers 84:` and a pair of bell-cranks 85. VSaid cam rollers 84 are journaled on the outer ends of a horizontal shaft 86 kwhich eX- tends transversely over said die. `This shaft 130 bellecranks 85 are substantially identical withn135 the bell-cranks 67 and arranged inthe samej Shortlinks 88 connect the lowerends` of the long arms of the bell-'cranks 85 to the ends of the ejector bar 66. In the bifurcated short arms of the bell-cranks 85 are'upper cam surfaces 89V and lower earn surfaces 90. The bell` cranks 85 arekpivoted to` bearing brackets 91 similar to the bearing brackets 62 and secured tothe sides of the block25 in the same manner. From the above description `it is evident that it is necessary to placea bottle under lthe' cap.- ping head and cause the sameto functionand when there is no bottleunder the capping head `the ejector slide is not ;operatedto feedacap'l@ i145 r which center. the same'. y
