6, an enlarged perspective view ofthe ignates the plates frames which serve of a pair of yoke plates or to maintain the desired operative relationship between the other parts of the capper. Said plates 1 each have a long vertical slot 2 and preferably have their lower portions approximately from the lower ends of their respective slots laterally spread or offset to accommodate between said plates 1 the wider portions of the stirrup-shape jaw members 4 which are pivotally mounted on and connected to the respective plates 1 by means of headed pivot pins 3, each of said jaws 4 thus serving as a connecting element between the plates 1 to thus connect said plates 1 together.

The jaws 4 will preferably be connected to each of the plates 1 by pivot pins 3 at points equidistant, or approximately equidistant, from the longitudinal central line of said slots 2 of the respective plates 1 as illustrated.

A pair of operating levers 11 and 12, preferably having their outer ends of loop form and their shanks or bodies of two spaced plates, and preferably with said plates disposed in interleaved relation, have their lower end portions preferably interleaved with, and pivotally connected to, the upper end portions of the jaws 4 by means of pins 5.

A vertically extending preferably elongated U-shape thrust bar or post '6 has the hood 8 mounted thereon by means of the rivet 9 or any other usual and suitable means or method of attachment or may be welded thereto, and has its sides or legs disposed upward preferably parallel to each other and preferably straddling the interleaved levers 11 and 12.

While it is not essential that the thrust bar or post 6 shall straddle the levers 11 and 12, or that said levers 11 and 12 shall be interleaved with each other or with the ends of their respective jaws 4, this construction is preferred. 7 In any event the levers 11 and 12 are to be pivotally or otherwise connected together in such manner that their movement toward and from each other will cause equal swinging movement of the jaws 4 about their pivots 3 toward and from each other, and the said levers 11 and 12 are to be so related to the thrust bar or post 6 and to at least one plate o other part functioning similarly to plates 1 as to cause relative endwise movement between said plate 1 and thrust bar or post 6 as the levers are swung toward and from each other.

A construction whereby the foregoing relative movements may be obtained is shown in the several embodiments illustrated wherein a pin 10 having its end portions respectively disposed in the respective slots 2 of the respective plates 1 and having its extreme end portions upset or spread to engage the outer faces of the respective plates 1 passes through the legs of the thrust bar 6 and through the interleaved plates of the levers 11 and 12 disposed between said thrust bar legs 6 at a point equidistant from the axes of the pivot pins 5, so slidably and pivotally connecting said levers 11 and 12 and the thrust bar 6 with the plates 1 and pivotally connecting said levers 11 and 12 with each other and with the thrust bar 6.

Each plate 1 will preferably be formed with two guide lugs 'I bent or presented inwardly at right angles from its side edges adjacent the lower end of its slot 2 and so spaced and presented as to slidably engage with the adjacent edge face of the adjacent leg of the thrust bar 6, and so serving to center said thrust bar 6 and. the hood.

8 carried thereby with relation to the plates 1, and hence with relation to the jaws at all times.

The jaws 4 will have their opposed lower transverse bar edge faces notched out in registry to define between them when closed an opening to receive the neck of the bottle being capped. Said jaws 4 will preferably be of relatively heavy resilient or springy sheet metal so that they may spring or yield without being deformed when gripping bottle necks of slightly greater diameter than usual or which may have some slight imperfection, it being recognized that there will be some variations, within a limited range, in the diameter of the necks of bottles to be capped.

The capping hood 8 will be of usual construction with a cushioning element, such as a pad of rubber 13, disposed in the upper part of its interior so as to be interposed between a bottle cap A and the opposed face of said hood 8 to cushion the thrust of the latter in the final capping operation. I

Also a cap-retaining spring device 14 will preferably be provided for said hood, said device 14 being, in the embodiment illustrated, a U- shape resilient member or spring straddling the hood 8, secured between the same and the thrust bar 6 by the rivet 9, and having legs extending below the lower edge of the hood 8 and having inwardly presented outwardly curved extreme lower end portions extending below the lower edge of said hood 8 and adapted to be forced apart by a cap A during the insertion thereof in the hood 8 and to snap inward toward each other as the lower edge of the cap A is moved upward so as to extend slightly inward over the edge of said cap A and thus retain it in the hood 8 preparatory to application to a bottle.

The levers l1 and 12 will preferably have their lower end portions slightly downwardly offset as illustrated so as to conveniently space the handles 11 and 12 from each other when they have been swung upward to their extremeupward positions, thus giving more room for conveniently gripping and holding said levers 11 and 12 as moved to and from such position without risk of the operators hands being pinched or bruised. However, this risk is small and,- while the offset construction is preferred, it is not essential.

In operation, the levers 1'1 and 12 are moved so as to move all parts tothe position shown in Fig. 1 wherein shoulders 4 of jaws 4 strike opposite edge faces of thrust bar 6, thus preventing further movement of the levers 11 and 12 toward each other, a cap A is inserted in the hood 8, said cap first spreading the legs of the holder 14 and then being held by the same in hood 8, all as illustrated in Fig. 8.

The cap A as held in hood 8 is then fitted on the top of a bottle B extending upward between the jaws '4, when the levers 11 and 12 are swung downward, causing the plates 1 to move upward, and the jaws 4 to move upward toward the hood 8 and 'to simultaneously swing inward toward each other until they firmly grip between them the bottle neck B as the end of the swinging movement of said jaws 4 is reached, as illustrated in Fig. 2. V

Continued movement of the levers 11 and 12 thereafter results in a slight downward final capping movement of the thrust bar 6 with its hood 8 as illustrated in Fig. 3, at which time the lower edges of the levers l1 and 12 strike against the shou ders 4' and 4 of jaws 4, effectively preventtive pivot pins 3' essential that they should be made connected to the upper end ing further spreading movement of s'aidlevers 11 and 12. I p

Obviously, since, as illustrated'in- Figs. 3' and 5, all portions of the gripping jaws 4 lie below the plane of the portions of the handles normally gripped by the operator, the tool may be employed to cap bottlesin a case without obstruction by, or injury from, adjacent bottles in the same case. In the modification illustrated'in Figs. 9 and 10 the construction and operation are the same as in the preferred form except that-instead of the guidelugs '7 integral with the plates '1, plates '7' having inwardly presented guiding lugs bent up along the'edges of the respective plates 1' are secured respectively to plates 1' by rivets or any other suitable means.

In the modification illustrated in Figs. 11 and 12 the construction and operation are the same as in the preferred form except that only one plate 1 with its slot 2 receiving pin 10 is used, and instead of the guide lugs 7 the staggered outer ends 4' and i of the respective jaws 4 engaging the adjacent edges of the respective legs of the thrust bar 6 serve to center the same with its hood 8 in the extreme upper position of the levers 11 and 12; that is, in the initial position of all parts of the tool preparatory to applying a cap A to a bottle B, the thrust bar 6 being otherwise unguided throughout the capping operation and I being maintained in centered position by the bo tle B as gripped between the jaws 4 after the downward movement of the levers 11 and 12 has begun. In this said modification, instead of using two plates 1 with slots 2, one said plate 1 sufiices for guiding the pin 10 and equalizing the movement of the jaws 4; which, however, will have their opposite side tied together by a lint; 1 having its respective end'portions pivotally connected to said jaws 1 by pivot pins 3', the respecand the respective pivot pins 3 having common axes.

In all embodiments all elements, excepting the rivets and pivot pins, are so designed and con-' structed as to be capable of production by sheet metal stamping operations, as illustrated.

Also, the levers 11 and 12 are formed with rounded edges to avoid sharp corners or cutting edges and may well be formed from suitable lengths of metal strap that'is available on the market in varying widths and with smoothlyv rounded edges.

Said levers 11 and 12 are preferably made of loop form to give awide hand grip, but it is not of loop form, or that they should be interleaved, or that there should be two distinct levers extending beyond the point of their pivotal connection by the pivot pin 10.
