CAN-GAPPING MACHINE. v

Application filed April 3-, 1926. Serial No. 99,650.

This invention relates to acan capping machine, the general object of the invention being to provide means for placing friction caps on cans, with means whereby the device can be used with different sizes eral views, and in which Figure 1 is an elevation, with parts in section, of the device. 7 v

Figure 2 is a view of the piston, with parts insection.

c Figure 3 is a view of the split-spring ring usedwith the piston.

In thse views,l indicates the base of thc device and 2 indicates the upright connected with thebase and having a horizontal part 2 which is provided with the vertically ar ranged bore 3 which is of two diameters to receive the stem 4 of the piston 5 and the spring 6 which surrounds the upper part of thestem. An arm 7 extends upwardly from the upper partof the upright and has a tapered hole 8 therein which receives thetapered end of a handle 9 which has a hole therein to receive the upper end of the stem 4, the stem being pivotally arranged in the hole by means of the pin 10. The piston 5 is formed with the reduced lower part which is provided with the annular groove 11 in which fits a split spring ring 12. This reduced part enters the cap, shown at B', with the upper edge of the cap engaging the under face of the large part of the piston so that this part tends to force the edge against the top of the can. The spring ring 12 will engage the cap and hold it in place on the piston, and by making this ring of spring metal, it will act to hold caps of different sizes on the piston so that the machine can be usedfor capping cans of different sizes.

The can A to be capped is placed on the base 1 in front of the upright, 2 and under the piston, 'thecap B having been placed on the piston, as shown in dotted lines in Figure 1. Then the handle isdepressed. which forces the piston downwardly so that the cap 1s pushed into the can top and thus the can will be sealed. The spring will return-the i parts to raised position as soon as pressure is removed from the handle. ring will hold the cover squarely on the piston, so that it'will not tilt'when being forced into the mouth of the ca The device will insert the cap without injuring either the can or the cap.

. It is thought from the foregoing description-that the advantages and novel features 7 of my invention will be readily apparent. i I deslre it to be understood that I may make changes in the construction and in the combination and arrangement of the sev-' eral parts, provided that such changes fall within the scope of the appended claims. ,l Vhat I claim is r p I 1. A can capping machine comprising a base, an upright thereon having a horizontal upper part which has a vertically arranged hole therein, a stem passing through the hole, a piston on the lower. end of the stem formed with a lower reduced part to receive a can cap, an upwardly extending arm on the upright having a tapered horizontal hole therein, a handlehaving a tapered end fitting in the hole for movably connecting the handle with'the arm, means for pivoting 6O The spring the handle to the stem and a spring onthe stem betweenthe handle and a part of the upright for holding the piston in raised position. i

2. In a can capping machine, a piston or chuck having a reduced part for entering a 1 can cap, said part having an annular groove therein and a split spring'ring seated inthe groove for causing the said piston or chuck to fit can caps'of different sizes.

' In testimony whereof I afiix my signature. SILVIO PETREGCA.
