ing had to the accompanying drawing, and

to the numerals of reference marked thereon.

The invention relates to new and useful improvements in bottle capping heads, and more especiallyabottle-capping head of the type wherein the head remains in a fixed position and the bottle cap is crimped 01' secured to the bottle merely by inserting the bottle with the cap applied, into the head.

An object of the invention is to provide a bottle-capping head of the above type, where in the parts shall be of simple construction,

positive in operation, and wherein the cap may be tightly crimped on to the bottle neck regardless of any slight inequalities in thesize or shape of the neck.

A further object of the invention is to provide a bottle-capping head with a plurality of crimping aws, which are normally which are brou ht into held separated, and

of the crimping action by inserting the neo bottle into the crimping head.

'lhcse and other objects will in part be obvious, and will in part be hereinafter more fully descril'icd.

In the drawings,- Figure 1 is a sectional view through our improved-head, showing the parts in their expanded position ready to receive the bottle neck; Fig. 2 is a similar view with the spring also ln section, and

showing a bottle neck inserted in the crimping head and the parts in final crimping position; Fig. 3 is a bottom plan view of the crimping head; Fig. 4 is a horizontal sectional view through the head at the' point where the crinniing jaw engages the cap. Fig. 5 shows a bottle neck with the cap crimped thereon. Fig. (3 is a detail showing a cap prior to being crin'iped on the bottle.

in carrying out the invention. we provide a suitable shank 1, which may be mounted in any desired way, sous to hold the head in a stationary position. Said shank has an outwardly extending flange 2, and said flange carries the cylindrical body portion 3. The body portion 3 is provided with a shoulders 12.

plurality of radial slots 4, (see Fig. 4:). In each of the radial slots we have provided a wedge-shaped member 5, which to. ers from its upper end toward its lower on In the rear of each of the wedge shaped members 5 is an elastic backing 6, which may be of rubber or any other suitable substance.

Each of the radial rooves 4 also receives a crimping jaw 7. T e jaw has a tapered face 8, which is adapted to cooperate with the tapered face 9 on the wedge member 5. The jaw 7 at its upper end has a laterally projecting portion 10, and at a distance below said laterally projecting portion 10 is a laterally projecting shoulder 11.

Within the space formed by the projecting member 10 and the shoulder 11- is a spring ring 12, which enga es each one of t e jaws and normally ten s to press the jaws out-ward, so that as the jaws move up and down they will remain in contact with the wedging members 5, and move outwardly and inwardly, according to the direction of movement of the jaws, toward a center line passing through the crimping head.

- The jaws are cut away so as to provide The crimping head has at its lower end a cap 13, which cap is secured to the cylindrical body portion 3 and to the flange of the shank portion by suitable bolts 14. The cap 13 is cut away to form a central opening, and extends into the path of the shoulder 12' on the crimping jaws 7, so that said cap will limit the downward movement of the crimping jaws and retain the jaws within the crimping head.

The inner face of each of the crimping jaws 7 is cut away so as to form inwardly projecting ribs 145 (see Fig. 3). The jaws 7 are centered around a chuck 15, which is so shaped as to extend between the projecting member 10 and the shoulder 11. This chuck is, however, made of such diameter that the jaws may slide inward on the chuck to the extreme inner crimping position, as shown in Fig. 2.. The chuck in its lower face is provided with a pocket, shaped so as to receive a cap 16 placed on the neck of the bottle 17, and allow the crimping flange of the cap to extend beneath the chuck.

The chuck has a stem 18, which extends up into a cylindrical recess in the. shank 1 of the crimping head. A spring 19 is located in said recess and bears upon the upreduced at its lower end so as to form a 19 normally holds the chuck in its ower,

ledge or shoulder 22, which receives the collar 20, and may limit the downward move- 115 18119 of the spring 19.

In the operat'on of our device, the s ring position, as shown in F ig. 1, and in this position the jaws 7 are carried downward and the spring ring 12 has forced the jaws outwardradially, so as to open the crimping head ready to receive the neck-of a bottle. A cap 16 is placed on the neck of a bottle, such as shown in F ig. 6,.and the .cap and neck are together inserted in the crimping head. The pocket in the chuck will receive the cap, and as the bottle is forced upwardly into the crimping head, the cork or other flexible material in the cap will be crowded down into the mouth of the bottle by the pressure whichis necessary to overcome the tension of the 5 ring 19, before the chuck can move upwar ly. By increasing the tension on the spring 19, the pressure exerted upon the cork before the crimping action takes place may be varied.

As the chuck moves upwardly, the jaws 7 are carried therewith, compressing the spring rin 12 by reason of the fact that the tapere face of the jaw slides up the inclined face of the wedge members 5. This will cause an inward movement of the jaws, which will engage the fian e of the cap'and bend the same underneaththe re: taming rib at the upper end of the neck of the bottle. 4 The upward movement of the bottle may be continued until the cap has been properly crimped and secured to the bottle. The flexible backing located in the rear of each of the wedge members which control the ac.--

tion of the jaws, yields so that the jaws may conform to any irregularities in the shape of the mouth of the bottle.

Whilewe have described our crimping head as a stationary head into which the bottle may be moved, in order to perform the crimping action, it will be obvious that from certain aspects of the invention the.

crimping head may be moved vertically relative to the bottle, which may be held stationary, and said crimping head will operate in precisely the same way to crimp the bottle cap.

The lower ends of the jaws are tapered outwardly,-so as to properly guide the neck of the bottle and cap into the capping head. Inasmuch as the jaws are normally held in their extremeoutcr position, that is, with the head expanded there will be no crimpin action whatever applied to the flange o the cap until after the cap has been seated in the chuck and suflicient pressure up lied to the chuck to overcome the tension 0 the spring 19. Therefore,'the cap will be firmly seated in the mouth of the bottle before the crimping action takesplace.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is i 1. In a bottle capping head, the combina tion of a chuck, crimping jaws, each of said jaws having spaced projections for corrugat'-' 8c ng or crimping the cap, means for normally ho ding the jaws out of contact with the cap and an independently yielding means for each jaw, for positively forcing the same inwardly to crimp the cap, said jaws having their inner faces at their lower ends tapered outwardly so as to guide the cap and bottle head into the chuck.
