and use the same, reference being had to the.

This invention relates to means for ap plying caps to bottles,'jars and the like and it consists in certain improvements, whereby the caps are made to be secured in sealing relation to the container in substantially the following way: lhe cap, in superim posed position on the container, is first so acted upon that spaced portions of the edge part of its fiangeare firstloent downwardly, said edge part initially standing more or less in a laterally projecting relation whereby to be conveniently impinged by the bending means under a vertical thrust whereupon the remaining or interinediate spaced portions are bent downwardly, the result being the inward displacement of the portions .firstbent down and their consequently suming a locking engagement .with the shoulder on the container; An advantage of this manner of applying caps to bottles and the likev is that the edge part, made sinuous after the first bending-down operati on, possesses resilience and elasticity so that, although the movement of the bending tool is constant and, particularly in the case of plain uneorrugated flanges, might othegwise break the heads of the containers or fail to secure a proper locking engagement of the caps therewithwher'e the heads varied appreciably in diameter, the yield thus afforded compensates for such irregularities of diameter in the" container heads and makes a substantial sealing, without danger of.

breaking the heads, possible.

My invention consists, briefly stfi ted, in a cap-bending head, or sealing-head. having an open cap contracting cavity ozt less nor} mal diameter than the portion of the cap to be thereby operated upon when forced thereint0,' the cap-surrounding portion of said cavity having its internal diameter in substantially its lowest part approximately as little as any relatively higher internal diameter thereof and being'composed 0t cap-edge bending devices spaced from each other. A sealing-head, thus constructed, is adapted to perform what I hereinafter term the first operation. in the attaching of a cap with such effect on the cap that'the portions of the edge of the latter first bent down e., by the spaced devices) may each assume a position approximating a right angle with relation to their original position; although it should be understood that such a sealing head would not be incomplete for performing not only the first but the second operation, since by properly adapting the spaced devices to'the purpose they may be made to ride over the portions of the cap not first bent down (and standing between them after the first operation) upon in'iparting rotary movement either to the sealing-head or to the bottle and cap, as will hereinafter appear.

The invention willv be found fully illustrated in the accompanying drawii'1gs wherein,

These bending devices are arranged in the slits existing be tween the ribs t in the manner shown in Fig. 2, their toes projecting inwardly; in their normal-positions they abut against the enlargement'p, as shown. I

plunger 1 is arranged to-slide vertically in the socket, its lower endortion having the annular groove2 and pro ectin into the sleeve; the groove receives the en -portions w" m" of the bending devices and has such width as to allow somevertical movement-of the plunger withoutits actuating the bending devices.

A spring'l pcoiled about. the plunger and interposed between the flange normal position of the parts. the lower face of theplunger is preferably so high above the lower faces of the projections that a cap placed in the recess produced will impinge against the plunger at its top and against the projections at its flange edgeportion. When the treadle is depressed, the

cap being already placed in position against the plunger lt) (the plunger being magnetizcd to hold it there), the bottle mouth impinges against the cap and raises it and the plunger; the first effect; of this is to draw downwardly the spaced portions B of the edgeportion of the cap flange, .the roundedfedges of the projections 15 allow ing the latter to slip freely over the portions B. lhe interrnediate portions 15' are left substantially in their original positions during; this part of the o eratioh, but as the pressure; on the treade 18 continued, the

faces 16 of the tool (existing between its project-ions) impinge againstthe portions l-i of the cap. flange and draw them downwardly; the flange edge-portion of the cap being, by this operation now contracted or turned in bodily, the cap is substantially wholly'received within the tool, its portions 15 being looked under the shoulder on the bottle. When the pressure is now relieved, the plunger presses downwardly and causes its capped head to clear the tool.

Figs. 9, 10 and 11 show constructions in \VlliClii-ll operation of turning-the flange edge-portion into locking engagement with the shoulder on the bottle bv a ulyinsz pressure'against the portions 13' of the cap flange is effected by means operating transi'erscly oit'said portions B.

.lnl ig. 9 the head I) of the pedestal has a bore in which slides the hollow stem 17 of a socket 18, the latter-being penetrated by a mandrel 1.) limited. against vertical movement in socket 18 by a thrust collar 20 bearing against the upper end of the stem and by a shoulder 21 abutting against "an anti-friction bearing device 29 located in a cavity 23 of the socket. The lowerend of the mandrel is concave to receive the cap. ,Head Z) has a 1111625 secured to it By screws 26, and to the nut is secured, by

screws 27, a dome 28. The mandrel has its upp r end threaded. at 29, and working in the nut 25 and it carries a stop-collar 30. A spring pressed cup 3t. having a hardened bearing-piece 32 engaging the mandrel, is arranged in the dome and normally forces the mandrel down; when the mandrel is raised. its threaded connection with the nut will-cause it to rotate, as will be obvious. Screwed to the socket is a cap 33 acting to hold in place radial arc-shaped segments 34 arranged in corrcspondiugly shaped grooves formed radially in socket S and each carrying a roll as. The rolls form the bending tool in this instance, and they normally stand in contact with the lower end of the mandrel, as shown, being held in this position by pins 37' penetrating the socket and the head I) and ha vino heads 38 arranged in countersinks 39 in the latter, the pins bcing pressed downwardly by springs ll) 111- terposed between them and adjusting screws el-l tapped into head (1. "The diameter of the circle outlined by the inner or acting portions .of the rolls approximately equals that of the body of the can-A. so that when the cap is placed ih position, its flange will abut against the nmler faces of the rolls, being there held by the rolls, which may be magnetized. In closing; a bottle with this type of mechanism, the first part of the operation is substantially the. same as in the first two types, the mandrel"resisting at first the upward pressure thereon of the cap,

whose flange, through the rolls, tends to displace it upwardly; spaced portions ii of the cap flange are therefore drawn downwardly, leaving intermediate spaced portions substantially as they "were. At the end of the operation of drawing downwardly the portions B the bottle and cap exert a pressure on the mandrel which is attirst sufficiently yielding, owing to the re =ilience of the disk (I, to bring the edge-portionof the cap flange in a plane below the shoub der on the bottle. but ultimately positively displaces the mandrel upwardly, which then rotates and rotates with it the bottle and cap one effect of this rotation is to cause the rolls to ride overthe portions B,, and, by turning them down, displace the edge-portion of the cap flange bodily inward into locking engagement with the shoulder on the bottle. A further client may be to augment the locking action between the ca'p and bottle head, because the upward movement of the socket 'following that of the inindrel increases the degree of compression of springs 40, with the result that the rolls spin the flange edge-portion into more or less continuous contact with the bottle head.

'In Figs-l0 and 11 the rolls have no move rnent except on their own axes, and cap holding'fingers are provided.
