,BOTTLE-CAPPING' MACHINE.

Application med January 27, 1'9'26. serial Np. 84,088.

My invention relates, more particularly, to machines for applying caps, such as metal caps required to be bent into place, to the mouths of bottles to seal them; primary object being to provide a novel', simple, sturdy and inexpensive type of bottle capping machinekwhich will be highly eii'ective in operation. l

`Referring to the 'accompanying ingzj Figure 1 is a view in side elevation of a bottle1-capp1ng machine embodying my im-` provements. Figure 2 is. a section taken at the line-2 2 on Fig. 1 and viewed in the directionE of the arrows; and Figure 3, a section talrenfat the. line 3 on Fig.- 1 and viewed in the direction of the arrow. l

Referring to the particular illustrated embodiment ot' my invention, the machine comprises a base member 4 shown asy adapted to be secured, as by bolts 5, to a' table or other support upon which the bottles to` be capped rest, it being understood` that, if desired, the base member 4 may be provided with a plate' extension to overlie. the'v support. and serve as the meansl for directly supporting the bottle tofbefcapped. RisingY from theA base 4fis anupright 6' formed of a rod which, by preference, extends atits f lower end into an.V upwardly openingsocket (not shown.) in theA base- 4 and in whichl the upright 6 is securely. positioned by ascrew 7 vtl-ireadedin' the base. 4y andengagingY the side of the upright,the upright 6. beingI o-circular shape in cross section through'- out its length-except at the flattened Side portion thereofrepresented atrS;

The. uprightf 6 forms.- a support Jfor a vertically adjustable capping-head 9 shown as of a form presenting a plate portion 10 carrying rearward-ly extending vertically. spaced apart lugs 11V containingv circular vertically aligned openings therethrough` through which the upright 6. extends, this l head having slidin-gfit on the upright. The

opposite edge portion of the Vplate portion 10 isv provided with vertically spaced apart lugs- 12, and: 13 which containv vertically aligned apertures in which al capping-elefis verticallyv re:- c-iprcca-ble; The capping-elementi is-Ormed off a, rod, in the openings in the lugsl12'anc'l13, and al cup 16 secured to th-e lower end of the rod below; thelug'li a'nd'p'rovided for enor stein, portion 15y which slidesv to, the lug 12, and between this stop pin and the bottom wal-lof an upwardly-opening socket 18 in the lug1j3, a coil spring 19 surrounding, the rod 15 is interposed.

The means shown for depressingthe cap* ping-element14 comprise a lever 20 having a Ablfurcated portion 21l at which it straddles the head 9 and to which latter it is ypivotally secured as by the pivot pin 22,

the arms ofthe bifurcated portion 2l of the lever v bearing against the. ends of` the cross pin 17', whereby when the lever 20 is depressed, it forces the capping-element downwardly againstv the resistance of the spring 19.` Y

The means employed for holding the head 9 in vertically adjusted position o n the upright 6, to adapt the machine for applying. capsto bottles` of ld itlterent heights, comprises a friction-plate device formed of a pair of plate`s-23 and' 24 containingapertures 25 through which the upright 6 eX- tends, these apertures being of thev same shape as the cross-sectional contour ofA the upright 8, but of slightly larger size than the crosssectional area of the lupright, whereby these plates are adapted for slight tilting movement relative to the upright'` The.4 inner ends of the plates v23- and 24, whicharelocated in the space between the lug-s 11, arefbifurcated asrepresented atv125,`

toy provide the1 spacedV lugportions 26 `and plates, .andfthus theentirehead 9, to the up-v fight kand thereby holdy the heed Securely against: ver-tical displacement' 0n' the. upright: daring' the caprins! Operation The y Plates -yond the lugs lltherebyrendering them ac.

cessible to be grasped and pressed together by the operator, against the tension ofthe spring 30 to release the frictional grip between them and the uprightand thereby permit the head 9 to be slid up or down on the upright to any desired position of adjustment, the friction-plate structure just described operating automatically, when the operator releases his grasp on the plates, to securely grip the head to the upright.

In the-particular construction shown, and in accordance with the preferred embodiment of my invention,'the

plates

23 and 24 serve to prevent rotation of the head 9 on the upright, Vdue Vto the shaping of the openings 25 therein to generally conform with the cross-sectional contour of the upright G.

It will be understood from the foregoing that a capping machineconstructed in accordance with my invention is not only of simple and durable construction, and adapte ed for ready and positive operation, but also is of relatively inexpensive construction, one of the features thereof rendering the machine of relatively inexpensive construction being that of providing the upright 6 of noncircular shape in cross-section and providing means Von the head for preventing the head from turning on the upright preferably by so shaping the openings in the

plates

23 and 24 that turning thereof on the upright is prevented. In this connection it will be noted that the necessity of forming the openings through the lugs 1l of non-circular form with attendant expense is avoided.

Vhile l have illustrated and described a particular construction embodying iny in-v vention, I do not wish to be understood as intending to limit it thereto, as the same may be variously modified andaltered without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

l. A. capping machine comprising an upright of non-circular cross-section, a capping head slidable along said upright, and friction clutch means on said head and engaging said upright for holding said head in vertically adjusted position comprising friction plates having openings therethrough through which said upright extends, said openings being so shaped as to prevent turning of said plates on said upright.

2. A capping machine comprising an upright of a cross-sectional shape partially circular and presenting a fiat side surface, a capping head slidable along said upright, and friction clutch means on said head and engaging said upright for holding said head in verticallyl adjusted position comprising friction plates having openings therethrough through which said upright extends, said openings being so shaped as to provide porv tions which cooperate with the flat side surfaceV of said, upright to prevent turning of said plates on said upright.

3.. capping machine comprising anY upright, a capping head slidable along said upright, and a clutch device on said head for holding the latter in adj usted position on said'upright comprising a shoulder on said head, a plate lapping at one end with said shoulder to fulcrum thereon and having a portion which engages said vupright and a spring for tilting said ,plate into clutching position'relative to said upright.

'4; 'A capping machine comprising an upright, a capping head slidable along said upright, and a clutch deviceon said head for holding the latter in adjusted position on said upright comprising' shoulders on said head, a plate presenting a recess in one end flanked by spaced apart lugs, said lugs lapping said shoulders to fulcrum thereon and having portions which engage said upright and a spring for tilting said plate into clutching position relative to said upright.

5. A capping Amachine comprising an upright, a capping-head slidable along said upright, and a clutch` device on said head for holding the latter in adjusted position on said upright comprising spaced Vapart sets of shoulders on said head, plates each presenting a recess in one end flanked by spaced apart lugs, said lugs lapping said sets of shoulners, respectively, to fulcrum thereon and having portions which engage said upright and a'spring for tilting said plates in opposite directions -into lclutching position relative to said upright.

6. A capping machine comprising an up'- right of a cross-sectional shape partially circular and presenting a flat side portion, a cappingV head having spaced apart bosses containing circular openings therethrough through which said upright extends, said head being provided at its opposite edge with sets of shoulders spaced apart, and means on said head engaging' said' upright and preventing turning of said head thereon Vcomprising plates containing' vopenings therethrough through which said upright extends, said plates being located in the space between said bosses, the inner ends of said plates containing recesses flanked by spaced apart lugs, said lugs lapping said sets of shoulders. respectively,` to fulcrum thereon, and a spring interposed between said plates and yieldingly forcing the latter in opposite directions, the openings in said plates being of a shape corresponding substantially to the cross-sectional shape of said upright thereby *forming an interlock between said plates `and said upright preventing said plates, and therefore said head, from turning on said upright;
