To all whom it may concern: a

Be it known that I, PETER C. LIEBER, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and usefulBottle-Capping Machine; and I do hereby declare that the following is a full clear, and exact description thereof, reference being had to the accompanying draw ings, in which like letters refer tolike parts.

This invention relates to bottle capping machines for securing and clenching caps to bottles.

The particular feature of this invention consists of means associated with the plunger of the bottle cappingdevice for marking the cap of the bottle or otherwise aliixing to it some indicating mark.

This is accomplished by means of a peculiarly designed die on the end of the head of the plunger which will engage the metal cap and stamp an impression thereon. The object of identifying the cap of the bottle by some peculiar mark is to enable a particular bottle capping machine plunger to be identified as the plunger which capped a particular series of bottles. Where certain bottles are poorly cappedso that the contents of the bottles are liable to be damaged, it has, heretofore, been necessary to examine all plungers or machines to discover which one is improperly capping the bottles, while by means of this invention the defective plungeior machine may be readily identified.

The bottle capping machine shown herein is the same as that shown in my Patent No. 1,170,241 of February 1, 1916. However it should be understood that this invention is not limited to any particular kind of bottle capping machines.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

Figure 1 is an elevation of a bottle and the upper part of the bottle support and a central vertical section through the crowning head. Fig. 2 is a perspective View of the plunger and plunger head showing the indicating means thereon. Figs. 3, 4, nd 5, are plan views of the caps of bottles after having been capped by three separate capping plungers. Fig. 6 is a detail elevation, partly in section, of a bottle capping machine,

showing thereon. H

In the drawings there is a bottle 10 for which a support 11 is provided,.the upper. end of the bottle projecting into the rigid. crowning head,

tapering throat 12 of the plate. 13. As shown in Fig. 1, the bottle is in position to have a crown. 14 applied thereto, the :bottlesupport l1 and crownin head being relatively movable as is usual in this class of machines, as will be readily understood'b-y those skilled in the art. Aswill be seen from the drawing the spring encompassing sleeve on the plunger is in engagement with and stopped by the plug 19 to positively limit the upward movement of the plunger at the instant that the throat 12 of the capping plate 13 limits the upward movement of the cap' andmouth of the bottle 10. Within the casing15 extending upward from said head plate there is a cone trally located plunger 16. Said plunger has a shoulder near its lower endbelow which ra contracted portion or head 23 of the plunger projects through a vertical opening concentric with the throat 12, but of smaller diameter than said throat, as shown. Above the shoulder 17 a spiral spring 18 acts downward, said spring surrounding the plunger and engaging the lug 19 which screws into the upper end of t e casing 15. Therefore, said plug 19 is vertically adjustable and by it the tension of the spring 18 may be regulated and the upward movement stopped.

A sleeve or barrel 21 surrounds the spring 18 and lies between it and the casing 15 and rests upon the lower shoulder 17 of the plunger but stops at a point somewhat below the plug 19 near the upper end of the plunger so as to permit ample compression of the spring. A look nut 22 is screwed on the plug 19. The casing 15 and screw plug 19 are arranged so that the plunger will have only a slight movement and the upward movement is yieldingly limited by cooperation of the spring and the plug 19.

As the throat and plunger wear, the wear plurality. of capping plungers working surface of said head there is adie 24 which may be in the form of a letter or number or any other identifying mark. The

'die 'is adapted to mark or impress on the crown the figure or design thereof as shown in Figs. 3, 4 and 5.

In this manner the capping machine whose head is provided with the letter A will impress the mark 25 on the crown 14 so that all bottles having crowns with this mark thereon may be identified as having been crowned by the cappin plunger or machine with the letter A. Li ewise all bottles having themark 125 on the crown 11a may be identified as being capped or crowned by the plunger or machine having that particular die. And likewise the bottles having themark 225 on the crown 214. Therefore, as represented in the drawings shown herein, three difierent crowning plungers have capped'the bottles with the crowns, 14, 1-14:,an'd'214. If one of these crowns is defective it will beevident that the capping plunger having that particular die on its head will be the one which is out of order and it may therefore, be readily traced and repaired. Y

In Fig. 6 the material portion of a bottle capping machine is shown, having in it a plurality of plungers 15. There is shown the hopper 30, the upper portion being partly broken away. 31 is the main shaft revolving the crowning head, and 32 is a casing surrounding the vertically movable bottle supports 11.

The invention claimed is:

1. In bottle capping apparatus, a plural-ity of plungers for capping bottles, and

means on the capping head of each plunger for making an identifying mark on the caps operated on by such plunger, the identifying means on the various plungers being diflerent from each other.

2. A bottle capping machine including plungers for capping bottles, and means on the capping head of each plunger for making an identifying mark on the caps operated on by such plunger, the identifying means on the various plungers being different from each other.

3. A bottle capping machine including a plurality of plungers for capping bottles, and acapping head on each plunger having a specially shaped die on the capping face thereof for engaging and forcing inward parts of the cap marking each cap for identifying the plunger head operating on a cap, the plunger heads of the various plungers having different dies upon the capping faces "thereof.

In witness whereof, I have hereunto afiixed my signature.
