The object of the present invention is a device for hermetically closing from a distance openings in the walls of ships, such as hatches, doors and windows.

The device includes a closing means intended to cover the opening to be closed and which will hereafter be designated by the general term of panel; this panel which is provided with a frame the movable sides of ywhich can be pressed beyond the edges ofthe A. panel and be drawn back within these edges,

is combined with a piston adapted to be operated by fluid under pressure, the pisrection'moves the panel before the opening to be closed, then presses this panel against the edges of the opening, and finally acts upon the sides of the frame pushing them beyond the edges of the panel, in order to press them (the sides of the frame) against the j walls framing the opening to be closed by the edges of the panel, so as to produce hermetic closing of the opening. By its movement in the other direction, the piston rod i Vcauses the withdrawal of the sides of the 'i way of illustrating the manner of carrying out the object of the invention, a device for closing a hatchway.

Figure 1 is a plan View of the hatchway shown in longitudinal section. Fig. 2 is a section through the line A B of Fig. 1 with the closing device in sight. Fig. 3 represents a plan View the frame of the panel on a larger scale. Fig. 4 is a detail, of the frame on a'larger scale. Figs. 5 and 6 are partial sectional views of the closing device showing the panel in two diiferent positions. Fig. 7 shows a detail partly in elevation and partly in section through the line C D of Fig. 5. Fig. 8 is a transverse section of the panel and the guides therefor.

luis the opening to be closed,such as ahatchway, and 2*L the panel intended to cover this opening; this panel 2aruns in the guides 19 which grasp the panel on two opposite edges (Figs. 1 and 8). In the portion of the guides which are situated opposite the opening 1, the flanges thereof facing the opening are discontinued (Fig. 2) so as to permit of pressing the panel against the edges of the opening when once it has been carried in front of the same.

Within the panel is set a frame Separately shown in Fig. 3; the sides a, b, c, l of which are movable in such a manner that they can be pushed beyond the edges of the panel 2, that is to say so as to project beyond these edges as is shown in Fig. 6, and be drawn back from these edges (Fig. 5). The side .A of the frame is rigid with a rod l having in its middle part notches 6 and 7 one of the edges of each of which is sloping; at its extremity the rod bears an articulated hook 8. The sides and (l adjacent to the side a are rigid with the posts 2 and 3 the feet of which engage with the notches 6 and 7, these feet presenting a slanting edge corresponding to the sloping edges of the notches; the rods 4 and 5 are articulated on one end with the rod 1 `and on the other end with the posts 2 and 3, while other rods 30 and 31 are ar ticulated at one end with the posts 2 and 3 and at the other end with the posts 40 and 41 rigid with the side c; the extremities of these posts 40 and 41 engage with notches in the posts 2 and 3; these extremities and these notches have, the same as posts 2 and 3 and notches 6 and 7, corresponding sloping and slanting edges. Rods 34 and 35 rigid with the rod 1 engage at their extremities in the notches of the rods 2 and 3, which notches have sloping edges to which are applied the extremities of the rods 34 and 35, in a similar manner the extremities of rods 37 and 38 rigid with the posts 2 and 3 engage in the notches 38 and 39 provided in the posts 40 and 41. By pushing the rod 1 from right to left (Fig. 3) the side a and simultaneously the other sides b, c and d are moved outward, the rod 1 acting on the posts 2 and 3 of the sides Y) and l by the rods 4 and 5, and on the extremities of these posts by the sloping edges of the notches 6 and 7, while the posts 2 and 3 for their part acting on the posts 40 and 41 of the side o through the rods 30 and 31 and on the extremities of these posts through the sloping edges of the notches, which these extremities engage. By pulling the rod 1 from left to right, the sides b,0and cl are simultaneously with the side a, brought back by the tractive action of the rods 4, 5, 30 and 31 on the posts 2, 3, 40 and 41, and the pressure of the extremities of the rods 34, 35, 36 and 37 on the sloping sides of the notches of the posts 4, 5, 30 and 31, in which these extremities engage. (See Fig. 4.)

The corners of the frame a, c, and al are fitted with triangular caps 32, which are impelled forward by the sides a, Z9, 0, and al when the latte-r are moved outward and are drawn back with the sides of the frame by the action of these sides on the gudgeons 33. To the panel 2a is affixed a button 11 which engages in a slit 11a of a metallic strip 12, fastened to a wedge 13 secured to the extremity of the piston rod 10 which is operated by fluid under tension. On the sides of this wedge 13 are arranged sloping grooves 22 in which engage the hooks 21 attached to the panel 2a (Fig. 7). A toothed hook 23 is attached to the wedge 13.

Communicating with the ends of the cylinder 27 are conduits 2G and 28 for the admission of the fluid under pressure, and also communicating with the ends of the cylinder are conduits 26a and 2S2L for the exhaust of the fluid.

To close the hatchway the fluid under pressure is allowed to enter the cylinder-27 through the conduit 26. The piston together with its rod will be pushed toward the left (Fig. 1) and the wedge 13 secured to the piston rod 10, by acting on the panel 2a, which is prevented by the guides 19, from moving in a direction perpendicular to the guides, will push this panel before it, and will finally place it in front of the opening 1a (its position in Fig. 5) in that part where the guides of the panel are eliminated on the side toward the opening; the piston continuing to advance, the panel can then move under the action of the wedge 13 in a direction perpendicular to the guides and will be pressed against the edges of the opening 1a (Fig. 6) during this movement the hook 8 enters into engagement with the hook 9, the tooth 23 of which, during the last part of the movement of the wedge 13, by its action on the hook 8, will push before it the rod 1, as the result of which there will be an outward movement of the sides a, b, c and d of the frame. By reason of this movement the sides a, b, c and CZ which were within the edges of the panel (Fig. 5) are pushed beyond these edges and pressed against the walls 24aL inclosing the opening 1a, opposite the edges of the panel. In order to Vassure a perfectly hermetic closing, grooves 24 are provided in these walls into which grooves the sides b, c and d enter in y their outward movement or expansion.

is a movement of the piston and its rod` from left to right (Fig. 1). During the first part of this movement the hook 9 by its action on the hook 8 with which it engages,

the first part of the movement of the wedge 13 from left to right, the same as in the corresponding part at the end of the movement of the wedge from right to left, has played freely from one extremity to the other of the slot. During the subsequent movement of the piston, the metal strip 12 will, by means of the button 11, exert a pull on the panel and will draw it from in front of the opening 1fL into the position shown in Fig. 1.
