Each slide plate 38 maybe attached to the corresponding uper or lower head as by screws 43. With t is construction each head upon the guide bars 35.

the arms and heads. Y

Eachof the lower heads 37 is provided at its upper edge with a curved flange 53 through which are adjustably mounted the fingers 54 he upper heads 36 may each be provided r g with a depending curved springar1n55 at eachend, to the lower inturned ends of which are connected 0 'posite ends of a flexible ehaln -or the like 56, tie central portion ofwhich is q connected to a bolt 57 flexibly connected to the lower edgeportiou ofthe head 36.

Certain of'the' fingers 54 ofthe lower head may be provided at their ends with reduced -pins 58 adapted to be received throughthe usual apertures formed in the "spring leaves 60.; r r

A plurality ofuprightsGl is located around the oil tank and supports the spaced upper and lower tracks 62 and 63 respectively which extend slightly morethan half-way around the tank; i i

The upper track 62 is arranged to be engaged, uponits under edge by the roller 48 carried by each-upper head 36 whilethe up till er edge ofthe lower'track 63'is arranged to e engaged by the roller 45 carried by each lowerhead37. a i a In this positionthe heads are held together in the position shown in Figs, 4 and and at B in Fig.1, clamping the springleaf, in cambered position, between the heads.

At theopening point the lower track 63 is movable inclined upward, at a slight angle, as shown at 63 and then extended horizontally, for a distance at the charging and discharging point, at a higher level than the remaining portion of the track 63, as shown at 63.

Beyond the charging anddischarging point the lower track descends at a sharper angle, at the closing point,-a.sshown at 63, again joining the lower level of the track 63.

The upper track 62 terminates atthe opening point at which is located a tapered section of track 62, the under edge of which is parallel with the section 63 of the lower track while the upper edge thereof is in elined upward at an angle thereto.

This section of track is joined to the hori zontally disposed-section 62?, at the charging distance substantiallyequal to the diameter of the roller 48, is a downwardly inclined section 62 joining the horizontal portion 62 of the up er track. i p i In t e operation of the machine, assuming the motor to beoperating and the magnetic brake released, when the magnetic clutch 19 is thrown in, the ring car 31 will be con tinuously or intermittent? rotated, through the gearing above describe rotating the arms and the headscarried thereby in the direction of the arrows shown upon the drawings. As each head approaches the opening point, the roller 48 of the up er head will. ride up- Ward upon the upper e ge of the tapered section 62 of the upper track while the roller of the lowerhead will ride between this tapered section 62 and the inclined section 63 of the lower track, thus separating the heads spring leaf may be removed from the heads and a red hot leaf ma be inserted therein, be

ing placed upon the ngers of the lower head in the position shown at- 60 in Fig. 1.

If desired, the magnetic clutch 19 and brake 20 may be operated to stop the movement of the machine during this discharging and charging operation, after which the move ment may be continued.

As the headsreach the end of the section 62", the lower head will be carried downward,

at a sharp incline, by means of theroller 45 passing down the inclined section63" of the lower track, while the upper head will move down to meet the same, the roller 48 thereof passing down between the inclined end 62.
