FILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 525,827, dated September 11, 1894.

Application filed December 22, 1893. Serial No. 494,466. (No model.)

To alZ whom it may concern:

Be it known that We, FRED WALLIS and GEORGE GALBRAITH, of Rochester, in the county of Monroe, in the State of New York, have lnvented new and useful Improvements in Filling-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact descripion.

Ourinvention relates to an improved filling machine, particularly applicable for inserting catsup and similar materials into bottles or other articles to be filled, and has for its obect the production of a device which firmly and practically supports the articles to be filled and practically and quickly inserts the material thereinto, without waste of the material or soiling of the outer face of the articles to be filled, andis so constructed as to unlformly and continuously fill said articles and permit them to automatically govern the flow of the material and to be readily and .quickly engaged or disengaged by the maconnected to one of the discharge tubes. Fig.

2 is an elevation of one of the detached spouts secured to the receiving receptacle for guiding the corresponding discharge tube. Fig. 3 is a vertical sectional view, taken on line 3-3, Fig. 2, and Fig. 4 is a vertical sectional View, taken on line 44, Fig. 3, the upper end of the discharge tube being shown in its normal position. A represents a supporting frame, which is of any desirable form, size, and construction, and is here illustrated as composed of upper and lower sections a a secured together by bolts or other suitable fastening means a B is a receptacle for receiving the material to be filled, and, as here illustrated, this receptacle is shown as cylindrical and as provided with a bottom wall I) inclining downwardly from its central portion.

In the preferable construction of our invention the receptacle B is rotary, and may evidently be actuated by any desirable form of mechanism.

At Fig. 1 we have illustrated a vertical shaft 0 extending lengthwise of the frame A and having its opposite extremities journaled in upper and lower bearings a a and its upper extremity extended beyond the bearing a and rigidly secured in any desired manner to the central portion of the receptable B. Near the lower end of the shaft 0 is a bevel gear 0 which meshes with a similar gear D upon a horizontal shaft D having one end journaled in a bearing a of the frame A and the other end, not illustrated, connected in any desired manner to suitable power mechanism, not necessary to herein illustrate and describe.

EE are a series of spouts arranged in a circle and depending at intervals from the depressed or outer portion of the lower wall I) of the receptacle B. Each of these frames or bodies is formed with a lengthwise guide E, and is provided at its upper end with an outlet chamber E opening from the receptacle B and communicating with the guide E, and at its lower end with a socket E communicating with the guide E and having its upper end extended above the lower end of said guide.

F-I represent a series of discharge tubes, each of which is supported by a corresponding spout E, and is movable in the guide-way E therein. Each of the discharge tubes F is formed with a closed top f and with an inlet opening or openings f in its side wall arranged normally beneath the bottom wall of the corresponding outlet chamber E and the lower end thereof is inclined outwardly from the lengthwise plane of the remaining portion of the tube, and is provided at its extremity with an outlet f Each of the spouts E is provided with a suitable valve G for normally closing the outlet f of the corresponding discharge tube F. As clearly seen at Fig. 3 each of the valves G is mounted upon the lower end of a stationary valve stem 9 passed longitudinally through the discharge tube F and having its upper end extended through the top fof said tube and secured to a cross bar a at the upper portion of the corresponding outlet chamber E The discharge tubes F are provided with engaging shoulders F guided longitudinally in the corresponding sockets E whereby, when the noses or upper ends of the articles or bottles 1 to be filled are inserted within said sockets, the shoulders F are engaged, and, by the upward movement of said articles to be filled, the discharge tubes F are forced longitudinally from their normal positions for connecting the openingf in their upper ends with the corresponding outlet chambers E and elevating their lower ends above the valves G for permitting egress from the outlets f of the materials to be filled.

When thearticles are filled their noses or upper ends are withdrawn from the sockets E and the discharge tubes F assume their normal positions, and effectually shut 0% the discharge of thematerial. This movement of the tubes F is facilitated'by springs F having their lower ends bearing against the shoulders F and their upper ends against shoulders e of the spouts E.

"When an article is being filled the lower end of the discharge tube is inserted within the same, as clearly seen at Fig. 3, to a plane separated a greater distance from the upper end of said article than the outlet f of said tube is separated from the valve G for closin g the same, and consequently, as the article is withdrawn, the corresponding spring F moves the tube F lengthwisely and engages the sides of its outlet opening f with the valve G before said article is withdrawn from the tube F, and the flow of the material to be filled is positively and efiectively cut off before the withdrawal of the discharge tube from the article to be filled. Moreover, as previously stated, the egress of the material from the discharge tubes is effected automatically upon placing the article to be filled in position on the machine, as thelengthwise movement of said article to such position moves the corresponding discharge tube F against the action of the spring F for holding the same in its normal position, and elevates the outlet j above the valve G. It is evident, however, that the elevation of the outlet f 2 above the valve G takes place only after the discharge tube is within the article to be filled, and consequently there is no liability whatever of the discharge, of the material to be filled, upon the outer face of the article for receiving the same.

In the foregoing description of our invention we have stated that the shoulders F of the tubes F are directly engaged by the article to be filled and the springs for forcing said tubes to their normal positions, but, in practice, we prefer, as shown at Fig. 3, to provide said shoulders F with yielding faces or washers F F which reduces to a minimum the noise incidental to the engagement and removal of the articles to be filled.

As previously stated, and as clearly seen at Fig. 3, the lower ends of the discharge tubes F are inclined outwardly from the lengthwise plane of the remaining portions of the tubes. This inclination of the lower ends of the discharge tubes serves to conduct the material to be filled directly against the side of the article to be filled and causes said material to flow down said side and permits the same to enter said article continuously and uniformly without the formation of bubbles and also permits the air to escape more practically and effectively than would otherwise be possible. The escape of air is also facilitated by drip or vent tubes H having their inner ends opening from the lower faces of the shoulders F and their lower yielding faces F and the central portions guided through slots or apertures e in the spouts E and having downturned ends h. material conducted therein into a receptacle I provided with upwardly extending arms 1 detachably engaged with a ring or other suit able support B having arms B attached to the lower wall I) of the receptacle B.

It will be readily apparent to one skilled in the art that, instead of providing the spouts E with outlet chambers E into which the outlet tubes E project, said chambers may be omitted and the outlet tubes may then project into the receptacle B, but this is not the preferable form of our invention, as we desire to prevent obstruction of the flow in the receptacle B by parts projecting above its lower wall.

J J are clamps for holding in position the articles to be filled, and, as preferably constructed, these clamps consist of levers pivoted at j to the spouts E and provided at their lower ends with shoulders or engaging ends j for engaging shoulders 2 upon the upper end of the articles or bottles 1 to be filled. The upper ends of the clamps or leversJ are provided with apertures j guided longitudinally along arms e projecting from the spouts E. These arms e are encircled by spiral springs J having'their inner ends bearing against movable shoulders e upon the inner ends of said arms, and their outer ends hearing against the upper ends of the clamps or levers J for forcing the lower ends of said clamps or levers to operative position.

As clearly seen at Fig. 2, the arms e are provided at their outer ends with movable shoulders e, which bear against the outer faces of the upper ends of the clamps J J. These shoulders e and the shoulders 6 previously mentioned, serve to both govern the movement of the clampsJ and adjust the tension of the springs J.

As clearly seen at Fig. 2 the lower ends of thelevers or clampsJ J are inclinedinwardly, and, in the practical operation of our machine, are readily forced outwardly by the upward movement along the corresponding tube The ends it discharge any.

F of a bottle or other article to be filled, and, as the shoulder 2 of said article passes above the shoulders or ends j, the springs J operatively engage said shoulders j with the shoulder 2, and said article is securely and of the shoulder 2.

In the practical operation of our machine the time of a portion ofthe revolution of the receptacle B is equal to the time required for the filling of an article byadischarge tube F, and consequently an operator stands at one portion of the machine and feeds unfilled bottles thereto, and another operator stands at a second portion of the machine and removes the articles when filled.

The operation of our invention will be readily perceived from the foregoing description and upon reference to the drawings, and it is evident that the same is simple in construction, is readily assembled in operative position, is easily and quickly cleaned, firmly and practically supports the article to be filled, inserts the catsup or other material uniformly thereinto without waste or soiling of the outer face of said article, and is so constructed as to fill the material rapidly and continuously, and to permit automatic control of the flow of the material by the engagement or disengagement by our machine of the article to be filled, and to enable ready and quick operation of the clamps for holding the same in position.

As the detail construction and arrangement of the partsof our machine may be readily varied without departing from the spirit of our invention we do not herein specifically limit ourselves thereto.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
