that the sleeve 13 is mounted for free rotation on the shaft 1.

Lugs 13 and 13, integral parts of sleeve 13, are provided with openings to receive a horizontal pin or trunnion 15 extending from a hub portion intermediate the ends of an arm 16, which might briefly be described as a rocker arm. An idling roller 17 in constant contact with cam12 is loosely mounted upon a pin 18. The axisofroller 17 V and the upper portion of pin 18 is offset'from the vertical axis of arm 16 and the lower part of pinlS,

. thus providing an eccentric adjustment of the roller 17 relative to the arm 16. j The pin18 may be secured by set screw19 in any position of adjustment'in the arm 16, and thus serves to determine the relative position of the arm; A flat sp'ring20 is'provided to act outwardly a ainst arm 16 below its pivotal support 15, thus causing roller 17' to make constant contact with the cam 12 face 'and'a thin annular rim or bead as illustrated, and set at an angle from the axis of arm 16, although itmay be desirable to use other types of crimpingto'ols depending upon 7 v the work to be done, is provided for positively crimping down or closing over the edge of the cap. It is suitably mounted upon alball or roller bearing'formed between a hub 22 integral with or secured at an angle to the arm16 in any suitable way, and the enlarged head of a pin 21 fastened into the hub by a pinorset screw. Y

. A companion rotatable die 24,1toco-operate 'with crimpin tool 21 is formed preferably with an annularbead or rimat th'e'lower end as illustrated, though here also it maybe desirable to use other types ofdies'to co-operate with any suitable form' of'crimping tool 21,

is" provided for beading or expanding outwardly that annular portion of the vertical wall'ofthe'cap'near its bottom in a manner such aswhen the cap is secured in the openins the said expanded portion will be immediately below the insideof the top of the can. Die 24L is-mounted at the bottom of pin 23 fitted into hte end of shaft 1 and held in position by a cross pin or set screw.

.7 'In the normal position of the parts cam 12 co-operating with roller 17'; will act through arm16 to release crimping tool 21 and, with the aid of spring will cause it to assume an outward position as shown. in Figure 5, to permit the introduction of the die '24tinto a cap placed loosely over the opening in-the can. 7 I

7 With the necessary clearance thus provided between the crimping tool 21 and die 24, the

latter is inserted into the upper end of the .3 A: c e ing tool 21, formed preferably with a beveled cap then maintaining the necessary pressure upon handle 2, the crank 6 is turned at a suitable speed through a number of complete revolutions, for example five turns.

By the power transmitted through the system of gears, sleeve 13 is caused to rotate about the spindle 1, whereupon the rocker arm 16, roller 17, and crimping tool 21 will be revolved bodily about the axis of sleeve 13. Roller 17 will be acted-upon positively by cam 12 during a portion of the rotation which action through arm 16 will'bring the crimping tool 21 as close to die 24 as is necessary to establish their working relation for crimping in the flange on the cap and for expanding the vertical wall of the cap near its bottom. The proper spacing or working relation of crimping tool 21 and die 24 may be adjusted to suit working conditions by means of the adjustable eccentric mounting of roller 17 on the oflset portion of pin 18.

It will be observed that the cam 12 also rotates and in the same direction as the rocker arm 16 and sleeve 13 above mentioned, but

preferably at a slower rate of speed, although in some cases it may be rotated faster, due to the difference in the size of gears 10 and 12, cam 12 making only four revolutions while rocker arm 16 makes'five. Thus for every .five turns of the crank 6 a relative movement of one revolution between the arm 16 and cam 12*1takes place. By means of this differential gearing an automatic feature-is developed, that-is, by merelyrmaintaining the necessary pressure upon handle 2 and turning crank 6, the crimping tool 2 1 is brought into working co-operation with the die 24 and forcibly held in this position by the cam 12 acting upon roller 17 while the tool is being revolved about the fiangededge of the capso that the flange on the cap is positively crimped and the annular'portion of the vertical wall of the cap is expanded. Afterwar'ds by mere continuation of the turning of crank 6 the crimping tool 21 is automatically released by action of cam 12* and spring 20 to permit the removal of the tool and its application'to another cap. I v

No extra manual means is required for rocking the crimping tool into and out of position. It will be understood that if the cam 12 is so formed as to rock the arm 16 against the action of the spring 20 during one-half of the relative movement of these parts, then during five turns of the crank 6 and five corresponding rotations of the arm 16, the tool 21 will be active for two and onehalf turns aboutthe cap, thus insuring the full crimping of the cap flange and'the full expanding of the cap wall. Obviously the gearratio and cam formation mentioned are suggested for purposes 'of illustration only and may be varied to suit the'conditions. For example,-gears 8 and 9 in lieu of having the same number of teeth, may have a differi If deslred, the devlce may, with slight mod1-.-

,it'will be drawn toward the tool 21 against 'ingco-operation with the die and permitting speed than the rocker armQ ewe-3 ent number, and produce a different gear 'ratio over allof the same. 5

Due to the factthatthe die 24 isrso ne-- what smaller than the opening in the cap,

the inner vertical wall of thecap and will I be frictionally rotatedaboutthe.spindle 1 byv i virtue of the contact with the cap. This is] the reason for mounting the" die rotatably on V the spindle and for lubricating the bearing.
