Considering Fig. 1, there will be noted a vertical groove 26 in the plunger 2, and arranged to slightly enter the groove is the lesser end of a rocker piece 27, and a pivoted pawl 29 has a circular head engaging the rocker piece movably. A spring 28yieldingly holds the rocker piece in the position substantially as set out in Fig. 1. It will be observed in Figs. 1 and 5, that a the pivots of the rocker 27 and pawl 29 arein substantially vertical alignment one above anv other. When the rocker is moved by the plunger from the normal position in Fig. 1 into the-raised position in Fig. 5, the engagement of the rounded head of the pawl with its seat in the rockerturns the pawl and causes its point to enter below the cap next to the lowest and tilt the same so that the lowest cap is no longer nested and may be pushed into capping position I v In' the operation of this invention it "is desired to serve caps 30 'into positions's'uch as illustrolling spring, and free the nose of the locking .5 plate from the patch of the stationary notched plate secured t'o'the casing; The cap serving mechanism now-operates, but the 'lowerendof the plunger has been raised well out of the :way of the served cap. On its downward movement the angular lever is moved "by the plunger and the sliding lock'plate again engages the notch. Thus,'-during' the actual capping action the cap serving inechanism is' held against accidental movement, and ready. toserve another cap. As the plunger lifts the lower end of thelongitudinal, groove therein is reached and the rocker piece is rocked so that the end of the pawl slightly tilts; the pile ofacaps above the lowest cap. The end of the plunge'rrises-above the end' of the rocker piece:.whichmay-"again assume the position in Fig. 1. .But whenthe plunger descends the rocker piece rocked downwardly until the groove is again presented to .its end as before. It is believed to be now made apparent that in the operation the plunger is raised out of the path of the served cap, and the overlying caps of the pile in the magazine are tilted to clear any nested condition and permit free service of the lowest cap into the desired capping position.

I claim as my invention:- v

1.-'In a bottle capping appliance, -a casing, in combination with a plunger movable in the casn a cap magazine for containing a pile of caps, cap, serving mechanism actuated by the plunger,

a pivoted pawl for temporarily tilting the pile of caps; above the lowest cap, a rocker piece arranged tooperatethe pawl, and the said rocker piece being operated by the plunger.

2. In a, bottle capping appliance, a casing, in combination with a'plunger movable in the easing, a cap magazine for containing a pile of caps,

cap serving mechanism actuated by the said plunger, a pivoted 'pawl 'for temporarily tilting the pile of capsabovethe lowest cap,-a rocking piece arranged-to operate the pawl, aspring for holding said rocker pieceyieldinglyin a predetermined position; I and the said rocker piece being operated by the plunger." 1

3. In a hand capper; the combination with a casing, of a hand operated capping plunger in the casing, cap serving m'echanism actuated by the plunger, said mechanism=comprising an angular lever having a downwardly extending arm, a cap'feeding slide connectedwith said arm, said lever having an upper arm provided with aslotted end, a sliding lockin the end of said upper arm, a spring controllingsaid lock, a lock plate carried by the casing and-arranged toenage the slidinglock. said casing having'a vertical slot, and a pin carried by the plunger and projecting through said slot and adapted tomove the said sliding lo'ck and the said angular lever.

4. a handcapper, the combination with a casing, of a hand operated capping'plungerin the casing, capserving mechanism actuated by the plungen said mechanism comprising an angular lever having an-upper arm providedwith a sliding spring controlled'lock', said casing hav ing a lock plate arranged to engage-the sliding lock, means carried by the plunger for releasing thelock and angular lever, and the said locking devices being constructed and arranged to hold the said cap serving mechanism inoperative during a part' of the plunger movement.
