WATER-TIGHT BULKHEAD-DOOR.

$PECIF1GATION forming part of Letters Patent No. 539,953, dated May 28, 1895. Application filed November 21,1294. Serial No- 529,434. (No model.)

To all whom it may concern.

Be it known that I, LEOPOLD KATZENSTEIN,

a residentof the city, county, and State of New, York, have invented certain new and useful Improvements in Water-Tight Bulkhead- Doors and Mechanism for Operating the Same, of which the following is a full, clear, and exact description My invention'relates to water tight bulk head doors and mechanism for operating the same, and has for its object to produce a construction by which the water-tight bulk head doors in navigable vessels maybe readily closed either from a point in proximity to the door or from points more or less remote from the door; for instance, the upper deck of the vessel.

To this end my invention consists of a bulk head door combined with mechanism for opening the same and holding the same open, and mechanism for disconnecting the bulk head door from the mechanism which operates directly to open it, in order that the doors may be automatically closed.

My invention further consists in the construction and arrangement of devices hereinafter set forth and claimed.

It will be understood that in this specification I will make reference merely to those kinds of bulk head doors which are fitted in the bulk heads of navigablevessels and are adapted to slide in a plane parallel with and close to the bulk head and cover and uncover the aperture or doorway formed in said bulk head, and being of such weight as to cause them to close with more or less violence when disconnected from their supporting mechan-j ism; but I will have it particularly under stood that I do not mean to limit myself to this precise form of door, as doors which are otherwise operated may be adapted for use with the mechanism which forms this part of my invention. I would also have it understood that the mechanism for opening the doorand the mechanism for disconnecting the door from its opening mechanism may also My invention will be understood by reference to the accompanying drawings, showing several forms of my construction, wherein- Figure 1 is an elevation of a bulkhead and its door'and the operating mechanism therefor, the same being one form of myinvention.

Fig. 2 is a side elevation of the construction away detail view of anotherform of releasingmechanism. Fig. 8 is a sectional detail view of the upper part of the releasing-rod shown in Fig. 1; and Fig. 9 is a plan view partly in horizontal section and on an enlarged scale, the section being taken through the plate h, hereinfter referred to.

Similar lettersof reference indicate corresponding parts in all the views.

Referring particularly to Figs. 1 and 2, A is a bulk head or dividing partition of a vessel. This partition is pierced for a door-way, and on either side of the door-way are vertical guides Cl. a within which the bulk head door works. This bulk head dooris composed of two sections (1 5'. These sections have mounted thereon wedges b b which co-operate with loose wedges b I) mounted upon the guides and adjusted by bolts b These sectionsb I) work in the guides or 0.,and sliding toward each other abut one upon the other and close the opening, the meeting. edges of the sections being beveled, as shown at b b in Fig. 4, in order to make a secure watertight joint, the wedges serving to.hold the abutting edges firmly together.

Carried by the section b is an arm 0, through which passes a rod D on which are collars c c, againstwhich thearm bears. This rod D is free to rotate in the aperture in the arm 0. The lower section of this rod D passes loosely through a guide or bracket E mounted on the bulk head, and terminates in astirrup F carrying a roller g. The axis of this roller g is prolonged and projects'into a groove or guide amounted upon the bulk head. Pivoted upon the bulk head in the path of the ICO roller g on the end of the rod is an operating mechanism therefor consisting of a lever G, one end of which is slotted, as with a slot 9', through which passes a stud g carried by the door section b. The free end 9 of the lever G projects into the path of movement of the roller g. It will be observed that as the doorsection b descends, the roller g, carried by the rod D connected to and moving with said door-section, will abut against the free end 9 of thelever G, and the door-section b and its connected mechanism being of considerable weight, will rock the lever Gon its pivot, thus raising the lower door-section in the grooves by the heft or weight of the upper section and its connected mechanism, and raising the door-section b in the guides to meet the doorsection b. It will be observed, however, that there is a certain amount of lost motion between the parts, thatis to say, the door section b musthave descended a short distance before the roller 9 contacts with the free end g of the lever G. This distance may be variously spaced according to the room left aboard ship for the play of the lower door. In the drawings I show that the section I) must have moved through one half its total movement before the lower door-section b begins to move; but any other proportionate movement may be had, by regulating the distance between the rod D and lever G. I would have it understood, however, that while I have described vertically slidingdoors and have set forth that the lower door-section is moved to close the door by'the weight of the descending upper door-section, I do not mean to thereby limit. myself to such a structure, as, for the purposes of this specification, doors sliding on horizontal or inclined lines and impelled by independent weights or other forces besides the inherent weightof the upper door, are the full equivalents of my vertically sliding doors.

The two door sections 19 and b constitute the bulk head door, but it will be understood that the door may be made in a single section, if desired. It will also be observed that as the door section b is raised, the door-section I) will descend by its own weight and the two oppositely moving sections will uncover the aperture in the bulk head, the relative times of movements of the parts being the reverse of their relative movements when the sections are brought together, as before described.

I will now proceed to describe the mechanism for opening the doors, having, as before,-

particular reference to Figs. 1 and 2. This mechanism consists of the threaded rod D provided with a gear 01' through which the rod freely slides longitudinally but which is splined or feathered on the rod to cause the rod to turn therewith. The threaded portion D of the rod passes through a split-nut contained within the box H. This split-nut is made in two sections it h which embrace the rod and may be engaged therewith and disengaged therefrom. Hung in a stirrup or bracket J, mounted on the bulk head, is a gear j which meshes with the gear 01, and whose shaft 7' is adapted to co-operate with a handle K for turning the same.

The operation of the door opening mechanism just described is as follows: Supposing the nut-sections h h to be engaged with the rod D, the handle K is turned, turning also the gearj and its meshed gear d which also rotates the rod D. The rod D, turning and being as aforesaid threaded and embraced and engaged by the nut contained within the box H, screws upward in the nut and is elevated bodily, carrying also with itthe door section b and allowing the door section Z) to descend by its own weight. This is the position of the sections as shown in Fig. 1.

Referring particularly to Figs. 5 and 6, h and h are the sections of the nut contained within the box H and which embrace the threaded section D of the rod D. These sections h h are provided with pins or studs h h which are entered into cam slots h 71. of a disk 71., to which is connected a gear 7?, which is held in position by the hub h. The gear h and disk 71, are capable of rotation, which rotary movement serves the purpose of separating the sections 72 h of the splitnut, thereby releasing the rod D and doorsection b, which thereupon descends and by the interaction of the rod D andlever 0 cause the section b to be elevated. The rotation of the disk and gear may be effected in various ways, the most direct being by means of a lever L which can be inserted'in the aperture Z in the gear M. For this same purpose I also provide an operating rodMfreely' movable in guides N N, and to which is connected at intervals pivoted operating levers n n, to the lowermost of which is connected a float O. Carried upon the operating rod M is a rack m which meshes with the gear 7?. It will be quite obvious that a longitudinal movement of the operating rod M will cause the gear 71 to be rotated, thereby separating the sections of the split-nut and allowing the rod D and door-section b to descend, as before stated. The longitudinal movement of the operating rod N may be effected by the movement of any one of the pivoted operating levers n, which operating levers may be located upon different decks so that the door may be closed from numerous points more or less remote from the door. Itwill also be observed that the closing will be done automatically should the water rise beyond a predetermined height for, if the water should rise beyond a predetermined height, the float will be lifted, thereby rocking the pivoted operating lever n, to which it is attached, and moving the rod longitudinally.

It will, of course, be understood that the mechanism for opening the split-nut and releasing rod D may be variously constructed, and that the split-nut itself may be replaced by any other suitable two-part releasing mechanism. In the preferred form of my invention, shown in Fig. 3, the door section b, which moves in vertical guides a a, is provided with the usual bracket 0 and rod D, which rod works in a guide E, as before described, and terminates in the usual stirrup F and roller g. The door-section b which, as before, slides in the guides at a, is provided with the usual stud g which works in a slot g of the usual pivoted lever G, the free end 9 projecting into the path of movement of the roller g, the mutual operations of the door-sections and their respective times of movement being the same previously described. Now, in the present case the door opening mechanism consists of a gear P mounted upon a shaft'p which is carried in brackets p p on the guides a a.

Mounted also upon the shaft 29 is a bevel gear Q which meshes with a bevel gear R carried upon a shaft 1- mounted in the bracket'19 Mounted also upon the shaft 1" is a wheel or crank S. Mounted upon the door-section b is a rack T which meshes with the gear P on the shaft 19. The operation of this form of my door opening apparatus is as follows: The wheel or crank S is rotated, thereby rotating the gear R and its meshed gear Q, thereby rotating the gearP and raising the door section b with its rod D, the door-section b sliding down by its own weight as soon as the pressure is taken off the free end of the pivoted operating lever G. The door-section bis held in its elevated position by a two-part releasing mechanism, which, in this instance, is a clutch consisting of a member s mounted rigidly upon the shaft and the member 75 held firmly from rotation but slidable laterally upon the sleeve 11 upon which it is carried.

12 is a shaft carried in a bracket 1), and has mounted thereon a cam-wheel o co-operating with the movable clutch member t, and agear U3 which co-operates with a rack 0 carried upon the usual operating rod M which is movable longitudinally and operated by means of pivoted operating levers n (see Figs. 3 and 8), one of which levers is operated by means of a float 0, as in the preceding example. The

operation of this form-of my construction is will permit the shaftp to rotate freely, thus allowing the door-section b to descend and raise the door-section b, thereby closing the opening in the bulk head. When, now, it is desired to open the door, the wheel S is roin order to hold the door-section b in its elevated position.

In the construction shown in Fig. 7, the clutch member if is operated by means of pivoted levers t t and stirrup t which engages therewith. I may also operate this form of mechanism by a longitudinally moving operating rod M and pivoted levern and float 0.

It may sometimes happen that the aperture in the bulk head will become obstructed by some large body, and the door-sections will not close together tightly. In order to prevent this, I provide a shield consisting of a plate a: lying across the threshold of the doorv and pivoted at w. This plate may also be provided with shields m which serve the purpose of keeping coal and other small obstructions out of the guides at a. It will be observed that as the door-sections close together, the lower section b will as it rises abut against the shield 00 and will swing the same on its pivot, thus removing from the path of the door-sections any ordinary obstacle, such, for instance,as a man standing in the door-way.

Having described my invention, What I claim, and desire to secure by Letters Patent,

1. The combination of a water-tight bulk head door consisting of two sections movable one toward the other and one of the said door sections being actuated by the movement of the other, mechanism for separating the sections and holding the same separated, and a two-part releasing mechanism for releasing the sections to permit them to automatically come together to cover the opening in the bulk head, substantially as described.
