The present invention relates to a liquidseal closure device for vertical,distillation re- `torts, consisting ot' a trough or gutter of quadrangular, shape, delimiting the discharge 5 opening and enclosing Water constituting the liquid seal,into Which there dips the downwardly-directed flange of a basin adapted to move in the manneroi a slide valve with horip Zontal movement under exerted upon one of its the action of a pull beine able to travel at its other end over in- I n `clined planes so as to be raised progressively,

to be freed from the trough or' gutter, to take up a horizontal position and to uncover| the discharge opening` by its further horizontal dis lacement. i y

hopper, delivering in front of this discharge opening, is continued downwardly,

upon the side Where the slide valve `is to lift,`

0 by a door adapte-cl to oscillate and to slide rial, such as curved,A bottomvvhich shape ofa circular arc of the saine centre as verticallyfvvhen the slide valve is lifted in order to comeinto a horizontal position, in such a Wayas to close the gap formed at the base ofthe hopper and necessary for the lifting movement ofthe slide valve. Y -This liquid-seal closure device may be combined with a device for retaining the material contained in vertical retorts for the distillation of coal or other combustible matelignite, peat, bituminous shales, etc." This device has for its object to reduce toI the minimum the force necessary for its operation and to econoinize the material by preventing any crushing during itsclosure. For this purpose the distillation chamber is extended at its lower end vby a gullet which comprises upon one of its sides a curved Wall presenting in section theshape or' a circular aro, While it isV open upon the other side, fa`cing Which there is pivoted, upon the supporting base of, the distillation chamber, a flap having the shape ot a basket, comprising a presents in section the that of the/opposite end Wall of the distillation chamber-this bottom of the flap being adaptedtoplaoe itself in prolongation of the curved surface constituting this Wall for a distance such that the material rests upon this Wall and upon this flap according toits natproduce its partial or ends, this slide valve Y that the material sliding over ural angle of slope7 Whilst in order to effect the discharge from the distillation chamber, it suices to tilt this flap in such a Way as to total effacement behind the end Wall of the gullet.

vThe accompanying drawings represent by Way of example one form of carrying out the material-retainingI device and the liquidseal closure device. l Y

Figure l is a vievv in vertical section, along the line l-l of Figure 2, and

`Figure 2 is a vieW in vertical section` at 90o with reference to the foregoing that is to say along the line 2%2 of Figure 1.

lEach of the chambers a of the distillation chamber is extended, at its base, by a gullet comprising upon one of its sides a curved Wall 1, which presents in section the shape of, a circular arc; the other side of this gullet' is open, the plane `of this opening b2 slightly inclined to the vertical, in such a Way the curved Wall has a tendency to escape from the gullet through this opening under the action of gravity.-

Upon the supporting traine c of the distillation chamber, facing this opening ,b2 of the gullet, there is pivoted at Z2 a skip or flap Z presenting the shape oitl a basket, of Which the bottom d? is curved and presents in section the shape of a circular arc having the saine centre the curved Wall b1 of the gullet; the pivot or axis of articulation (Z2 of this Hap is arranged laterally with regard to the chamber a of the distillation chamber, in such a Way as not to prevent its clearing at the moment of opening. The lateral cheek plates l of this tlap are arranged parallel to and externally of the corresponding Walls b of the gullet. A lever e, keyed upon one being l of the ends of the axis of articulation Z2 of rests, according to its natural angle of slope,

upon the surface of the curved wall o1 of the gullet and upon the bottom Z1 of the skip or basket; the latter must be raised more or less 5 considerably, according to the angle of this slope. l

In order to effect a more or less partial discharge of the distillation chamber' a, it sufices to move backthe flap l L1 more or less behind the gullet b, the bottom Z1 of this basket thus placing itself beneath the curved wall 121-, by actuating the operating lever e by hand.

The latter might likewise be actuated mechanically. This retaining device is preferably placed in the direction of the largest dimension of the distillation chamber, that is to say that the axis of articulation Z2 of the basket or skip cl (Z1 is arranged along a direction parallel to the direction of length of the distillation chamber.

It is easy to understand that the flap, during its movement for returnino` to the position for retaining the material irom its position of effacement, cannot grind or crush the material to be discharged, because this movement serves only to create a surface for supporting the material according toits natural slope, that is to say without the flap striking against a surface of any kind.

"The material, passing through the opening b of the gullet uncovered by the bottom Z1 of the basket d, falls into a hopper f g below a' box or caisson g provided at its lower part with a trough or gutter g1 of rectangular shape which defines an opening in the bottom of the box, containing up to a certain level, water intended to provide a liquid seal. This Atroughor gutterdelimits the discharge opening. Into this gutter g1 there dips the downwardly directed flange /tl of an inverted basin it; the latter comprises, along its longer sides, cheek plates ft2 directed upwardly, upon 'which are journaled, externally of the basin It, two pairs of rollers a', these rollers can run upon rails l fixed to the walls of the caisson g, above the gutter g1, along the longer sides of the latter. These rails are horizontal for the greater part of their length; near one of their ends, above the small sides of the gutter g1, they comprise inclined planes 2.

The basin It is connected, at the opposite end, to a rod h3, having a handle h4; when, by means of the latter, a pull is exerted upon the. basin 7L, the latter can travel in the manner of a slide valve; at the start of its movement, the rollers a' rising` upon the inclined parts 2 of the rails il, will produce at rst a gradual lifting of the slide valve basin 71 until the flange /tl is lifted completely above `the upper edge of the gutter g1 and the slide valve basin 7L comes to occupy a horizontal r position. By continuing to pull by the han- 6 dle h4 upon the slide valve 71 the latter is disand externally of the latter, there is arranged placed horizontally by means of the rollers 'l upon the rails l until the slide valve completely uncovers the discharge opening dclimited by the trough or rectangular gutter g1; the slide valve it takes up a position in the lateral prolongation g2 of the caisson g, which possesses dimensions suiiicient to receive the slide valve in its open position.

At the base of the hopper f, facing the lower extremity of the slide valve basin in the closed position, there is arranged a door la, suspended in such a way as to be able to oscil- 'late upon a horizontal spindle cl in guides 702 fixed to the lower part of the hopper f; this door c can oscillate and travel vertically in these guides when the slide valve 7L lifts in rising upon its rollers z over the inclined planes 2 of the rails 1. This door prevents the fall of material beyond the basin it, while allowing the vertical movement of the latter, forA kthe height necessary to free from the gutter g1 forming the hydraulic seal; this door 7c falls again by its own weight when the slide valve 7L is pushed back, by means of the rod 7a3 tt, into the closed position'in which the slide valve basin returns to engage in the interior of the gutter g1, descending by means of the rollers i along the inclined planes Water is brought into the gutter, forming a liquid seal, by a fitting g3 connected to the water pipe; drain pipes g4, connected to the base of the caisson g, g1, g2, allow the cleaning of thel latter.

y rihis arrangement of liquid seal insures a very gas-tight closure preventing any entrance of air, which is a condition difficult to fulfil for vertical distillation retort-s, generally of great height.

What I claim is:

l. In a liquid seal closure device for a vertical retort having'an open bottom for the distillation of combustible material, the combination of a casing having an open bottom, fixed in spaced relation under and adjacent the opening in the bottom of the retort and communicating with the latter by means of the open top of said casing, a/trough of quadrangular shape provided around the open bottom of lsaid casing so as to provide a container for a body of water, a basin constituting a slide Valve mounted for sliding horizontal movement within said casing and said basin having portionsprojecting into said trough adapted to be seated in said Water to form a liquid seal.
