To all 'whom 'it may concern: A

Be it known that I, Ross B. YERBY, a citizen -of the United States, and residing at Brooklyn, in the county of Kings and State a of New York, have invented certain new and useful Improvements in Bottle-Capping Machines, of which the following is a specication, such as will enable those skilled in the A art to which it appertains to make and use the same. This invention relates to machines for capping or'closing bottles and similar vessels or lreceptacles in which operation a flexible sheet metal cap is employed; and the object of the construction being in section, Eig. 2'

a view similar to Fig. lof that part of the construction shown in section but on an lenlarged scale and omitting some of the parts, the parts shown being in a different position, Fig. 3 a view similar to Fig. 1 of theparts shown in section but showing a modification, a transverse section on the line 4 4 o ig. 3, and ;Fig. 5 a side and face view'.

of a spring ring which I employ.,

In the practice of my invention, I provide a suitable support comprising a base a hav ing van upright orstandard a2 in whichv is mo nted a vertically movable plunger rod b.

The bottom ortion of the upright or standard -a2 is `ho low, and pivoted at the back thereof as shown at a3 is a -pedal lever b2 which passes through the bottom part of the upright or standard a2 and is connected with the lower end of the plunger rod b as shown at b, and a spiral spring b* is'connected ,with the outer end of the with the upright or stan ard a2 at b and normally holds the pedal lever b2 in a'raised position.

`Rigidly connected with the upper end of the unger rod b is an arm c having a ver- 55 tica y ,arranged pylindrical head o1' holder thereof is to provide 'an improved machine j of this class which is simple in construction are edal lever b2 and c2 with which is connected a tubular casing c3 this connection, in the form of construction shown, being made by reducing the lower endA of the head orholder o2 and provding'the reduced portion and the end of 60 the tubular casing with screw threads 'as shown at c4.

Placedl in-,the lower end of the `tubular casing 03 is a thimble-sliaped supplemental casing d the lower end of which is open, and

the casing d abuts at its upper end against lugs or projections c5 in the tubular casing' c3 and 1s h eld in said casing lby a7; ring Lor band c6 screwed thereinto.

a plunger e, the upper end of which is conical in form and provided with astem e2 which passesv upwardly through the top of the thimblfe-s'haped casing d and 'into a socket or recess e3 inthe-head or holder c2, 75

and placed on the stem e2 ofthe plunger e is a spiral spring'eIt which rests on a washer e5 secured to the stem'e2 of the plunger e vand which normally serves to depress said plunger,

Arranged ar und the plunger e within the casing d are rock aws f, twelve of which are preferably employed, and the rock jaws f are provided with inwardly and upwardly directed arms f2 and with downwardly and 85 inwardly directed heads f3 havino` inwardly directed noses f4, and the backs 0I saidjaws rovided with lugs or projections f5 whic enter corresponding recesses in the inner walls Aof the casing d, and placed around the upwardly and inwardly directed arms f2 of said jaws is a contractile spring ring or bandf, said ring or bland being shown .-in detail in Fig; 5, but this ring or band may bevmade in any desired manner. The -backs of the heads f3 of the jaws f are also provided with sockets or recesses j", and secured inthe ca sin al are pins or plugs f? which enter said soc etsor recesses, and while the jaws f are free to rotate on the lugs or. projections f5 the pins fsaid inholding said jaws-in position and retaining them in proper condition at all times. f

The upri ht or standard a2 is provided with a shel or support a? on which a bottle 105 gunay be placed, and in y improved bottle capping-machine is designed particularly .Y

for use in connection with a bottle cap h of well known forni and constructiomsaid ca i being provided with an outwardly an Placed in the thimbleshaped casingd is 70 downwardly directed flange or rim k2 pro-k scribed and claimed in an application for Letters Patent of the United States filed by me on the 20th day of October, 1908, N o. 458,598.-

In practice, the bottle g is placed directly under the head or holder c2 as shown in Fig. 1 and the cap/L is placed thereon. The neck of the bottle is provided at the top g2 with an annular bead, and with the parts in position as shown in Fig. l, the cap h being placed on the neck of the bottle, the pedal lever b2 is depressed. This operation forces the head -or holder c2 downwardly and the neck of the bottle with the capr L thereon passes into the bottom of the casing c?. In

this operation the top surface of the cap h5 bears on the lower end of the plunger e, and g said plunger moves upwardly slightly under the pressure of the spring e* and at the same time the heads f3 of the rock jaws f are forced 'outwardly and downwardly, and

as the pressure on the pedal lever b2 continues the plunger e movesinto the position 1, shown in Fig. 2, the upper ends f2 of the rock jaws f are forced outwardly and the' noses f* of the heads f3 of said rock aws are forced inwardly and the rim h2 of the cap is crimped or compressed around the bead g2 at the top ofthe neck of the bottle and the ears h3 of the cap are forced downwardly against the neck of the bottle as shown 'in Fig. 2. In this operation the bottle is securely closed, and when thepressure is re# moved from the pedal lever b2 the spring b4 j forces said lever and the plunger rod b -together with the head or holder c2 upwardly, and these parts return to the position shown in Fig. 1, and this operation may be repeated as often as desired, vand at each repetition thereof a bottle is capped.

In Figs. 3 and 4 I have shown a modification of the construction of the parts in or supported by the head or holder c2, and in this form of construction `the plunger e is slightly shorter than the plunger e shown in Figs. 1 and 2. With this construction four of the jaws f are provided with springs z' which are placed in recesses in the casing d l through which the pins f8 pass, and these springs normally serve toforce the heads of the jaws back of which they are placed inwardly as shown in Fig. 4. 4lNith this form of construction the caps L are first inserted into the holder as shown in Fig. 3, and the bottle g is supported as shown in Fig. 1. The noses f4 of the jaws f back of which the springs z' are placed hold the cap h in the position shown in Fig. 3 when said cap has once been inserted, and lwhen the'pedal lever b2 is operated or forcedudownwardly the head or holder c2 descends, and the top of the neck of the bottle enters the cap la; As

which -a number of bottles may be capped at a single operation; and my invention is not limited to the details of construction herein shown 'and described, and various changes therein` and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of'my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, isz- 1. In a `bottle capping machine, a vertically movableplunger head the lower end of which is provided with a tubular casing, a vertically movable spring depressed plunger mounted in said casing and the top portion of which is conical in form, a 'plurality of rock jaws mounted around said plunger and provided with inwardly directed upper endportions adapted to bear on the conlcal part. of the plunger and downwardly andY inwardly directed heads having inwardly directed noses, and a spring band placed around the upper parts of said rock jaws.

2. In a bottle capping machine, a vertically movable plunger head the lower end of which is provided with a tubular casing, a vertically movable spring depressed plunger mounted in said casing and thel top portion of which is conical in form, a plurality of rock jaws mounted around said plunger 'and provided with inwardly directed upper v end portions adapted to bear on the conical part of the plunger and downwardly and inwardly directed hea-ds having inwardly directed noses, and a spring band placed around the upper parts of said rock jaws, said rock jaws being also provided with lugs or projections which fit in the walls of said caslng I 3. In a bottle capping machine, a vertically movable plunger head the lower end of which Vis provided with a tubular casing, a`

vertically movable spring depressed plunger mounted in said casing and the top portion of which is conical in form, a plurality of rock jaws mounted around said plunger and provided with inwardly directed upper end portions adapted -to bear on the .conical part of the plunger and downwardly and inwardly directed heads having inwardly dii rected noses, and a spring band placed around the upper parts of said rock jaws,

said casing being alsoprovided with lugs or projections which fit 1n recesses formed in the backs of the heads of the rock j aws* 4. In a bottle capping machine, a vertically movable plunger head the lower end' of which is provided with a tubular casing,'a
