MEANS FOR PACKING SEMIFLUID SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 653,760, dated July 17, 1900. Application filed March 31, 1900. Serial No. 10,959. (No model.)

To all whom it may concern.-

Be it known that I, CHRISTIAN WEBJoRN- SEN, a citizen of the Kingdom of Norway, residing at Nedre Slotsgade 7, Ohristiania, Norway, have invented certain new and useful Improvements in Means for Packing Semifiuid Substances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to means for packing semifluid substances-snch as pomades, ointments, butter, and the like-in vessels.

The object of my invention is to provide means whereby such packing may be easily done and wherebyis avoided that air is mixed with the substances and inclosed with these within the vessel or box.

\Vith this object in view my invention consists in the combination, with a pipe leading from a receptacle containing the substance in question, of a plate fixed to or in suitable manner combined with the lower end of said pipe, said plate having a form corresponding with the cross-section of the vessel in which the substance is to be packed and a valve whereby the pipe may be closed or opened and whereby the space below the said plate may at will be connected with the atmosphere or shut off from the same. When using this apparatus, the said valve is set so that it shuts off for the pipe and opens for the atmosphere, whereupon the pipe, with the plate, may be carried to the bottom of the vessel or box, (or the latter carried upward over the plate,) whereby the air in the box escapes. Then the valve is set so that the air-passage is closed and the pipe opened, so that the substance in question may be pressed into the box from the receptacle or from a press. During this operation the plate, with the pipe, will be forced upwardly relatively to the box, (or the box downwardly,) the substance filling entirely the space underneath the plate, till the box is full. The box may be placed on a balance or on a table carried by a spring or springs, so that it may automatically give way for the pressure during the filling operation, or the pipe may be arranged to carry out an upward movement.

In Figure l I show one form of apparatus for carrying out my invention, the figure representing a vertical section through such an apparatus. Figs. 2 and 3 illustrate another modification. Referring to Fig. 1, A is the vessel or box, which is placed upon a table D, resting upon a spring B and guided by the rod 0. E is the feed-pipe leading from the receptacle. F is a valve shown in the form of a cock, and G is a plate the form of which corresponds to the cross-section of the box. The body of the valve is formed with two ways or passages viz., one inlet-passage H for the substance,and another passage T serving as an outlet for the air when the valve is turned ninety degrees. The latter of said passages corresponds with a passage K, formed in the valve-housing.

The substance in question is pressed into the box in the position of parts shown in the drawings, and when the box is full the valve is shifted to the position of the lever shown in dotted lines, after which the packed vessel may be replaced by an empty one. While the valve is in this shifted position, the air escapes from the box as the same is pressed upward by the action of the spring B.

Figs. 2 and 3 illustrate in sectional elevation and plan view, respectively, another modification of my invention, the valve being in this case constructed in the form of a tube pivoted between two plates,of which the lower is formed to fit the interior of the box, the apparatus being shown with the valve in its closed position. The plates a and b are rigidly connected together by means of stays c and are provided with central apertures d and e, respectively, whose diameters are equal to that of the tube f. This tube is interposed between said plates, being pivoted so as to turn on a counter-shaft g, journaled in the plates and capable of being shifted, by means of the lever it, between its extreme outer positions, (limited by the stops and it.) On said shaft and in connection with the tube is furthermore mounted immediately underneath the upper plate I) a disk Z, forming a closingdisk for the aperture of said upper plate. The feed pipe leading from the receptacle is screwed into this aperture, which in the position of parts shown in the drawings is closed toward-the box, while the aperture of the lower plate is open. When set in this position, the apparatus may be carried into the box in question,the lower plate being formed to accurately fit the interior of the same and the air escaping through the aperture of the lower plate. When the plate a has reached the bottom of the vessel, the lever h is shifted so as to bring the feed-opening, through the medium of the tube f, in communication with the aperture of the lower plate a. The substance to be packed may now be pressed into the box, this latter resting meanwhile upon a balance, or, as shown in Fig. 1, upon a spring-actuated table, so as to permit the parts to move relatively to each other during the filling operation. If the box be desired to remain stationary during the filling operation, the apparatus may be suspended and the pipe connecting the same with the receptacle adapted to be movable, (flexible or jointed pipes,) so as to cause the apparatus to move upward during the filling operation, the box remaining meanwhile stationary on the table. A red m, projecting to the levelof the lower face of the plate Ct, serves to indicate on the outer side of the box the progress of the filling operation. On shifting back the lever h the feed is stopped at once, after which the full box may be removed and replaced by an emptyone.

In many industries the packing of goods may be performed much more easily and accurately than hitherto by means of the apparatus above described.

1. In an apparatus for filling semifluid substances in boxes or vessels the combination with a pipe for carrying the substance to the box of a plate, having the same form as the cross-section of thebox to be filled and means serving to shut off the said pipe, said means being carried by the plate.

2. An apparatus for filling semifluid substances in boxes or vessels comprising the fol lowing instrumentalities, viz: a plate having the same form as the cross-section of the box, another plate, stays connecting these two plates rigidly together, said plates being the first name-d provided with a hole or passage, the last named with a similar hole to which a pipe may be connected, and a tube mounted between the said plates and carried by an axle by means of which the said tube may be carried in or out of correspondence with the said holes, the tube being at its upper-end provided with a disk serving as valve for the hole in the upper plate.

In witness whereof I have hereunto set my hand in presence of two witnesses.
