2 Claims.

Thisinvention relates to bottle capping maas an attachment for standard capping machine and to center a bottle for the capping operation, and to temporarily hold the cap in position accurately above the top of the bottle and below the '10 plunger in the operation.

This invention comprses a plunger chamber having the customary plunger therein arranged for vertical reciprocation, and in the path of the plunger carried by the Wall of the chamber are spaced levers pivotally attached and actuated only by the movements of the plunger in opposite directions whereby the bottom cap is tempo- ;rarily supported and the bottle is centered accurately beneath the plunger.

In the accompanying drawing there is illustrated the form of this invention believed to be best adapted for the purpose, and of such Simplicity ,of structure that the apparatus will not get out of order by continued or rapid'service.

Fig. 1 of the drawing is a vertical sectional view of a plunger chamber and a supporting member, showing this invention applied thereto. Fig. 2 is a cross section taken on the broken line 2-2 of Fig. 1. i

Throughout the drawing and description the same number is used to refer to the same part.

Considering the drawing, capping machines usually are provided with the member 1 arranged below the plunger devices and having an opening 5'; for receiving the top of the bottle 2. The caps are depositedone at a time from the cap magazine chamber 3 and are served upon the upper surface of the member 1 in the ordinary way. The cap serving mechanism constitutes no part 1 of this invention and is not shown. One after another upon and along the surface 4 the caps 5 are pushed into place below the plunger chamber 6 and plunger 7. The plunger is adapted for reciprocating movement in the chamber. In a suitable slot or slots in the wall of the chamber 6 are rocking levers 8 having the pivots '9 between their ends as illustrated. Any number of levers, as those designated 11 and 12 may be introduced, and this invention is not limited 9 to the particular positions illustrated in Fig. 2. It will be noted thatthe upper and lower surfaces of the levers presented to the plunger head are oppositely inclined, and in the operation of this invention the following condition of things 5 takes place repeatedly:-

' An upward movement of the plunger head into the position indicated by the broken lines in Fig.

1 Contacts with the upper inclin'es of the levers and moves the lower end thereof with the ledge or shoulder 10 into position to receive and tempo.- eo. rarily hold cap 5 exactly in the path of the plunger. 'As the plunger moves down it contacts with the lower inclines of the levers moving them away from the cap. It will be here 'noted that the same upward plunger movement that acts to hold the cap by actuating the levers, brings the lower ends of the levers against the top of the bottle, and as the levers are spaced apart the bottle islcentered in the opening of the member 1. The down ward or capping movement of the plunger re- 7 moves the shoulder 10 from beneath the cap and out of the way of the skirt of the cap 5, if as illustrated the cap is one of the so-called over-all pattern.

It is not intended to limit this invention to the precise shape and disposition of the levers or other parts, and itisvthought that the above explanation of the operation makes sufficiently. clear the fact that the levers are operated only by the movements of the plunger, and that no 30 springs are employed in this Construction.

Having now described this invention and the manner of its use, I claimz- 1. In a bottle centering and capping machine, the combination with a cap magazine, of a 5- plunger chamber adjacent thereto, a support i whereon caps may be served from the magazine to the plunger cylinder and having an opening 4 for the top of a bottle, a plunger adapted for reciprocating movement in said chamber, a plurality of spaced slots in the wall of said chamber, levers locatedin said slots and pvotally attached to said wall, each of said levers having above and below the pivot portions presented in the path of said plunger whereby the tops of the levers are moved outwardly by the plunger during its upward movement and inwardly by its downward movement, and each of said levers having at its lower end a portion formed and arranged to contact with and center a bottle in the opening of said support. g

' 2. In a bottle centering and capping machine; the combination with a cap magazine, of a plunger chamber adjacent thereto, a support whereon caps may be served from the magazine to the plunger chamber and having an opening to receive the top of a bott1e,` a plunger adapted for reciprocating movement in said chamber, a plurality of slots in the wall of said chamber, levers located in said slots and pivotally attached to said levers having at its lower end portons formed to contact With and center a bottle in said opening and a shoulder disposed to engage and position a cap during the upward movement of the plunger.
