APPARATUS FOR TREATING SKINS.

SPECIFICATION forming part of Letters Patent No. 673,125, dated April 30, 1901;

Application filed May 9,1899. Serial No. 716,135. (No model-) To all whom it pea/y concern:

Be it known that we, JOHN FREDERICK JONES, engineer, residing at 59 Haldon Road, Wandsworth, in the county of Surrey, and EDWARD SEYMOUR CLEGG, residing at 35 Drayton Gardens South, South Kensington,

.in the county of Middlesex, England, subjects of the Queen of Great Britain, have invented a certain new and useful Apparatus for the treatment of Hides and Skins, of which the following is a specification.

This invention relates to an apparatus for the treatment of hides and skins for use in the tanning, curing, or liming of the same and to apparatus for carrying out such treatment.

The chief object of our invention is to provide an apparatus in which may be treated a large number of skins in a thorough and efficient manner and in much less time than has heretofore been required, while the liability of the skins coming in contact with each other is avoided.

According to our invention we cause the tanning or other solution or liquid to flow in a constant stream over the surfaces of the hides or skins, which are arranged side by side at a suitable distance apart. We provide appropriate means for directing the solution or liquid over all parts of the surfaces to be treated and for reversing or changing the path of circulation of the solution, if desired.

In order that our invention may be clearly understood and readily carried into effect, we will proceed to describe the same more fully with reference to the accom panyingdrawings. It is to be understood that these drawings are by way of example only and that in practice the apparatus may be arranged to containa considerably larger number of hides than are here shown.

Figure 1 is a sectional elevation, and Fig. 2

a plan, of an apparatus constructed according to our invention. Fig. 3 is a view similar to Fig. 1, showing a modified-form of our invention.

Referring first to Figs. 1 and 2, a is a pit or tank constructed of suitable material. Near each end of the pit we arrange a partition d, inclosing with the false bottom 0 a space,within which the hides c are placed. The hides are suspended from a frame I), disposed over the pit. In the said partitions we provide two sets of aperturesfand g, three of each set being arranged, in the example shown, between adjacent hides and between the outside hides and the side walls of the pit. It is obvious, however,that any suitable number and arrangement of the said apertures may be employed. The apertures f are provided with funnels 71, having elongated flattened mouths, tubes, or other conduit-s for spreading the liquid forced therethrough. The apertures g are provided with valves, such as the clacks k, by which the passage of liquid from the outside to the inside of the partitions through such apertures may be prevented. In the space between the false bottom e and the actual bottom of the pit we form a channel m, in which We arrange a screw-propeller Z or a pump, paddle, or other means for compelling the liquid to pass through said channel in one or the other direction. It will be observed that the middle of this channel is of circular shape in cross-section, so as to fit the propeller, and that said channel is reduced in depth while being increased in width (as indicated by the dotted lines in Fig. 2) toward its ends, so as to distribute the liquid uniformly along the width of the channels or passages formed between the partitions (1 and the ends of the pit. Aperturesr are formed in the false bottom e, affording communication between the channel m and the receptacle for the hides. These apertures are provided with valves q, similar to the clacks 70, but disposed upon the receptacle side of the apertures. These valves qare preferably adapted to be maintained in a raised position by adjustable means, so that the quantityof liquid passing through the apertures r may be regulated. 'n is a heating or cooling coil for maintaining the liquid at any required temperature. The pit is adapted to be filled with liquid up to such a height as to nearly or completely submerge the hides suspended therein. The actuation of the propeller will then produce a circulation of the liquid, causing it to pass through the channel m-say from left to right -as indicated by the arrows in Fig. 1. The clacks is will the hides in such a manner as not only to be distributed over the whole surfaces thereof,

but also to maintain such hides in position and prevent their coming together or adhering at portions of their surfaces, and thereby hindering the action of the liquid upon such portions. The liquid will also pass up through the aperturesr, and thus serve to prevent the accumulation of sediment or layers of the liquid having increased density at the bottom of the receptacle. The liquid will not readily pass through the funnels in the opposite direction, and consequently the slacks over the apertures g in the partition at the leftby the liquid, as shown in Fig. 1, the liquid flowing through said apertures and being again drawn through the channel by' the propeller Z. We sometimes provide means for fixing the clacks 7c of those apertures 9 through which the liquid is flowing in any desired position, so as to check the flow of liquid through such ap rtures. We may, however, dispense with the apertures g and so form the funnels 77. that the liquid will readily pass through themin eitherdirec'tidn. If desired, the channels or assages formed between the partitions d and the' ends of the to enable the force or velocity of the circulating liquid to be increased. The how of liquid may also be regulated by adjustable valves disposed over the apertures f.

In the modification shown in Fig. 3'the artitions-d and their apertures are dispensed with, and instead thereof w snip-icy vortically-ar'ranged tubes or headers o, forming section. These tubesare closed or partially closed at the top and are perforated at the sides or surfaces adjacent to the hides, some or all of the apertures being preferably soarange-d as to direct the liquid delivered therefrom toward the center of the pit.

the example illustrated three such tubes, of different lengths or heights, are arranged on each side of the pit between adjacent hides and between the outside hides and the side Walls of the pit. The nungber of tubesand their lengths and arrangement may, however, be varied. The channel on is sitnilar in shape to that shown in Figs. 1 and 2. Apertures 1, provided with valves q, are provided in the false bottom in a manner similar to that described with reference to Figs. 1 and 2. In order that the shortest of thetu'beso that are toward the sideof the tank may receive a stream of liquid equal to that received by the other tubes, we may provide the lower end of such tubes with a flaring extension p, bent and directed towardthe cylindrical part of the channel in which the propellerl works, or We may effect this object by means of suitably-disposed baffle-plates.

It will be readily understood that when the propeller is actuated the liquid will be caused to flow past the same and rise in the tubes 0 at one end or side of the pit, from which tubes it will be projected through the apertures therein onto the surfaces of the hides. After traversing such surfaces the liquid will enter the tubes 0 at the opposite end of the pit and be again drawn through the channel m by the ropeller.- It will also be seen that in both of the forms of onr invention illustrated L the direction of the circulatidn (if the liquid j can be reversed by merely reversing the direction of rotation of the propeller.

hand end of thetank areautouiatically opened 5 It is obvious that instead of causing the liquid to now over the surfaces of the hides in a hor'izolital direction we sta so arrange the apparatus as to cause the liquid to flow vertically or at any inclination over' sdchsurfaces, either upward or downward.-

The circulationmay sometimes be effected partly by gravity, there being a reservoir above the pitto which liquid is-ptiniped from a channel or hollow at the bottom of the pit, thesaid reservoir-com inumoatingfwith spreadiiig channels, troughs, or funnels arranged above, at the side or end of, or between the 'j hides. pit may be closedat their upper ends, so as I Wear-o aware that the treatment of hides means have sometimes been used for agitating the tanning or other liquid to expedite the process by brir'rging'fre'sh portioi-isof the liquid into contact- With the surfaces; of the & hides. only partially effective, hecaiirse" the liquid }isonly disturbed and is not circulated and jdistributod through conduits, as in ouri npassages for the liquid, which tubes niay'conveniently be of circularo'r oval shape in orossi and is liable to bring them into contact with 3 each other, SO that they adhere 0V6! portions Such agitation, however,- is not or is proved method.
