HARRY L. VAUGHAN, or CHICAGO, ILLINOIS.

THROAT FOB, BOTTLING-MACHINES.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed December 19, 1910. Serial No. 598,002.

To all whom it may concern Be it known that I, HARRY L. VAUGHAN, a citizen of the United States, residing at Chicago, in the county of Cook and State .5 of Illinois, have invented certain new and useful Improvements in Throats for Botfling-Machines, of which the following is a description. I

My invention belongs to that class of devices known as throats for bottling machines for clamping crown caps on the necks of the bottles, and relates particularly to an improved throat and spring actuated dogs for retaining the crown in position, being in the nature of an improvement over the device shown in my pending application, filed January 15, 1910, Serial No. 538,184.

My invention has among its objects the production of a throat and its parts that is simple, durable, efficient. and satisfactory,

that may be used wherever found applicable.

To this end my invention consists in the novel construction, arrangement and combi- 2-5 nation of parts herein shown and described. In the drawings, wherein like reference characters indicate like, or corresponding parts, Figure 1 is a sectional view of a throat embodying my improved construction. Fig. 2 is a cross sectional view of the same, taken substantially on line 22 of Fig. 1. Fig. 3 is a cross sectional view taken substantially on line 33 of Fig. 1. Fig. 4 is an enlarged sectional view taken substantially on line 44 of Fig. 3. Fig. 5 is a perspective view of one of the resilient members. Fig. 6 is an enlarged sectional view, showing a modified construction.

Referring to the drawings, 1 represents a tubular casing of suitable material provided with an inwardly extending flange 2 at one end, and extended as at 2 at the opposite end, this end being preferably threaded to afford engagement with a re movable cap 5, which is provided with an inwardly extending flange 4. The throat comprises two annular rings, preferably of a hard or enduring material, arranged with in the casing 1 and provided with, a shoulder 7 and tapering bore for forcing the edges of the cap or crown C inwardly to engage the bottle neck. The throat rings or pieces 5 and 6 are retained within the casing by the flanges 2 and 4. Any suitable means may be employed for preventing movement Fig. 1. plurality of balls 12 of hard or enduring of the throat rings within the casing. As shown, I provide one or more pins or screws 8 in the casing, which engage with the ring 5. These pins, or their equivalents, may be arranged to engage the ring 6, if desired. A more satisfactory construction, however, for preventing movement of the ring 6 is to provide lugs or extensions 9 on one ring, as shown on the ring 6, adapted to fit in depressions or recesses 10 in the other ring. The throat pieces may be replaced when worn by removing the cap 3, and replacing one or both of the rings as desired.

To maintain the crown cap 0 in position when fed to the throat, before the same is forced upon the bottle neck, I provide suitable dogs, or their equivalents, arranged to support the cap substantially as shown in The dogs preferably comprise a material. They are positioned in recesses 11 in the extended end 2 of the tubular casing,'the ring 6 being provided with openings or holes opposite, or mating with the recesses 11. The openings in the ring 6 are of slightly less diameter than the diameter of the balls or spherical dogs 12, so that the balls will extend into the bore, or into the interior of the ring, but not pass or escape through the holes. The balls are preferably resiliently maintained in operative position, so that they will give to permit the insertion of the cap, and then spring out to support the same.

In the construction shown in Figs. 1 to 5, I show two springs, each arranged to control a pair of dogs, it being understood that .there may be any number of dogs desired.

The springs comprise the ends 14 connected by shanks 14 and are positioned in the recesses 11, a portion of part of the extensions 2 being cut away as at 15 to receive the shanks 14 The springs are provided with holes 19 in the ends, through which the balls 12 partially extend, so that the balls are maintained in position. They are also preferably offset or bent as at 16, so as to engage the notch 17 in the extended end 2 which prevents them from slipping endwise into" the recesses, but permits them to be readily removed after the cap 3 is unscrewed from the casing 1. The cap 3 may be locked on the tubular casing 1 by a set screw 18, or equivalent means, so that if openings or holes 28 for the admission or escape of fluids are provided in the cap and" dogs inserted as desired. With the construc tion shown, one or both throat pieces may be replacedwhen worn, as may the balls 12. By using ball dogs they may be made very hard and wear uniformly, giving greater efliciency.

In the modified form illustrated in Fig. 6, the lining or throat pieces 21 and 21 are provided, same being formed so that there is a shoulder 21 The balls 12 aremaintained in position by means of coiled springs 24:, which bear against plates 22, which contact with the balls. 'lhe opposite end of each of the springs contacts with the removable plug 24 in the cap. In this construction the balls and springs may be removed at any time by removing the plugs 23, or by varying the position of the plugs, the pressure upon the balls may be varied as desired. The plate 22 in this construction maintains the ball in. alinement with the hole in the throat piece, and aii'ords a very satisfactory Y bearing for the spring 24-.

Having thus described my invent on, 1t sobvious. that various immaterial modifications may be made in the same w1thout departing from the spirit of my invention,

hence it do not wish to be understood as limi'ting'myselt to the exact form, arrangement, construction or combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is chines comprising a tubular casing, provided with an inwardly extending flange at one end thereof, a removable lining fitting within the casing comprising a plurality of annular abutting rings fitting within said casing and seated againstsaid flange, the uppermost ring being provided with a tapered bore, and the lowermost ring being provided with a bore of greater diameter than the bore of said tapered ring and with an open ing extending therethrough, a movable detent' carried by the casing, and projecting through the opening in said lowermost ring,

and means carried by the casing and underlying said'lowermcst ring to normally'hold the lining within the casing.
