ALFRED L. WVEISSENTHANNER, OF NEW YORK, N. Y., ASSIGNOR TO THE PHOENIX CAP COMPANY, OF NEW YORK.

MACHINE FOR CLOSING JAR S.

SPECIFICATION forming part of Letters Patent N 0. 620,624, dated March '7, 1899.

Application filed November 10, 1898. Serial No. 696,093. (No model.)

To all whom. it may concern:

Be it known that I, ALFRED L. WEIssEN- THANNER, of New York, State of New York, have invented a new and useful Improvement in Machines for Closing Jars, which improvement is fully set forth in the following specification.

This invention has reference to machines or apparatus for closing jars, bottles, and similar receptacles of the general type illustrated in United States Letters Patent No. 590,196, granted to me September 14, 1897. In said patent the rowel or part for bending the lower edge of the holding-band under the shoulder on the neck of the vessel was reciprocated in a radial direction to follow the outline of a vessel of oval,rectan gular,or irregular outline by connection with a chain passing around a gage-plate, the rowel being in the form of a circular roller of proper peripheral contour. V

In accordance with my present invention I dispense with the use of the chain and gageplate for the purpose above indicated,employing instead a rowel of cam shape corresponding to the oval, rectangular, or other outline of the vessel, said rowel being mounted to rotate on a pivot fixed against movement in a radial direction and following the outline of the vessel by reason of its cam-shape, whereas in my patent above referred to the rowel was enabled to follow the outline of the vessel by reason of its radial movement. As in my former apparatus, the rowel of my present machine is flexibly mounted, so that it'can yield both in horizontal and vertical directions to allow for imperfections in the outline of the receptacle being sealed and avoid breaking the same.

Other differences in the construction of my present machine will be more fully underpart of the machine, and Fig. 5 an elevation of the complete machine.

Referring first to Fig. 5, A is the frame of the machine, and D is the supporting-plate, upon which the vessel or receptacle to be closed rests and which is movable to clamp said receptacle tightly in place by means of mechanism similar to that described in my patent already referred to, and which description need not here be repeated.

Referring now to Figs. 1 and 2, A is a depending shaft adapted to be secured in the overhanging arm of frame A by means of a set-screw a. On the lower end of the shaft is secured a plate 0 of a configuration con forming to the configuration of the vessel to be closed. Keyed on the shaft above said plate is a gear-wheel B, and loose on the shaft above said gear-wheel, a washer I) being interposed, is an arm E, having a sleeve 6 projecting upwardly therefrom around the shaft A. At one end arm E is provided with a depending handle F, by which it may be moved on its axis A, and at its other end it carries a slide 0, normally occupying the position shown in Fig. 1 by reason of the action of spring 01 around bolt 1), occupying a recess in the end of arm E, said bolt being screwed into the slide at one end and at its other end passing loosely through an opening in the arm E. Gisashaft passing upwardly through slide 0 and through a slot 1) in the arm E and being secured to the slide, so as to move and be movable with the same. Said shaft has a handle K. at its lowerextremity and carries a pinion H and a rowel J, rotatably mounted thereon and so connected as to rotate together. Pinion H meshes with gear-wheel B, and the latter being fixed, when arm E is moved around its axis, the pinion H, and consequently the rowel J, is rotated. I

In order to permit the insertion of the vessel to be closed between the plates D and C, it is desirable that the rowel J should be moved to the right from the position shown in Fig. 1 and retained in this position until the vessel has been securelyclamped in place. To that end I provide a lever L, pivotally mounted about the sleeve'e on arm E and held in place by a. bushing e around collar e.

One end f of said lever tapers to a point, which latter bears against an inclined surface h at the end of slide 0. As shown in Fig. 2, the lever is in position to allow the rowel to assume its innermost or operative position. By operating the lever to move the slide to the right the rowel may be moved outwardly and out of its operative position.

The parts of the machine illustrated in'Figs. 3 to 5 are the same as the corresponding parts in Figs. 1 and 2, except that the rowel is of such outline as to correspond to the rectangular outline of the vessel to be closed, and a plate M is secured to rowel J, so as to overhang part of the edge thereof and engage over the top of the plate 0, being particularly useful to prevent the dropping or drawing down of the rowel-plate (against the tensionof spring '6) in its action against the long straight sides of the receptacle.

The operation of the machine is as follows: The vessel having been clamped into place between the plates D and O and the lever L moved to the position shown in Fig. 2, the spring d, moving slide 0 and with it shaft G, throws rowel J into contact with the edge of the securingband on the receptacle to be closed. The operator now grips handles F and K and rotates arm E, in turnvrotating pinion H and rowel J, the latter by reason of its special contour following closely the outline of the receptacle and bending the holding-band under the shoulder of the same.

It is of course understood that various forms of rowels are to be used in accordance with the particular outline of the vessel to be closed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a machine for closing jars or other vessels of oval, rectangular and irregular outline, the combination with means for clamping the vessel in position, of a rowel, a carrier for the rowel rotatable about the axis of the vessel, and gearing for positively rotating the rowel as it revolves about. the vessel, substantially as described.

, 2. In a machine for closing jars or other vessels of oval, rectangular or irregular form, the combination with means for clamping the vessel in position, of a rowel, a carrier for the rowel rotatable about the axis of the vessel, and gearing for positively rotating the rowel as it revolves about the vessel, the rowel being of such shape that its periphery will closely follow the outline of the vessel without bodily movement toward or from the axis of the latter, substantially as described.

3. In a machine of the kind described, the combination with means for holding the vessel, a rowel, a carrier on which the rowel is rotatably mounted, the axis of rotation of the rowel remaining substantially fixed during the operation of closing the vessel, said carrier being mounted to rotate about the axis of the vessel, and the rowel being of such shape that its periphery will closely follow the outline of said vessel, and means for positively rotating the rowel during its movement about the vessel, substantially as described.

4. In a machine of the kind described, the combination with means for holding the vessel, of a fixed gear-wheel, a rowel-carrier rotatable about an axis coincident with the axis of the gear-wheel, a pinion rotatable on an axle carried by said carrier and meshing with the gear-wheel, and a rowel connected with said pinion so as to rotate and revolve therewith, substantially as described.

5. The combination with means for holding the vessel to be closed, of a carrier rotatable about the vessel, a fixed gear-wheel having its axis coincident with the axis of rotation of the carrier, a slide on one end of the carrier, a pinion meshing with the gear-wheel.

and a rowel connected to and rotatable with said pini0n,,b0th said pinion and rowel being mounted on an axle carried by the slide, a spring against which the rowel rests and which permits movement thereof in a vertical direction, a second spring pressing the slide toward the axis of rotation of the carrier, and a lever for moving the slide-in the Witnesses:
