DOOR FOR BULK-HEADS OR CO'MPARTMENTS OF SHIPS.

SPECIFICATION forming part of Letters Patent No. 549,843, dated November 12, 1895. Application fil d November 7, 1892. Renewed A rfl 10, 1895. Serial No. 545,151. (No model.)

To all whom it may concern.-

Be it known that I, FRANK W. CROSS, a citi- Zen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Doors for Bulk-Heads or Compartmentsof Ships; 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 appertainsto make and use the same. 7

This invention relates to improvements in adjustable water-tight doors for the bulk heads of ships; and it has for its object to so construct the door and the closing and fastening devices that the same maybe applied to the bulk-head without cutting or defacing the framing thereof, provide for securing the water-tight packing which closes the joint between the door and the opening at the bulkhead in such manner that an effective closure may be made with less clamping pressum and with less wear upon the packing than heretofore, and also to provide simple and efiective clamping mechanism for fastening the doors to the edges of the bulk-head openings, and, further, to provide for locking the clamping-dogs positively when the door is open and holding them in position to fall properly into place when the door is closed, as more fully hereinafter described.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which-- Figure 1 represents a plan view of a portion of a bulk-head door, showing my invention. Fig. 2 represents a View, partly in section and partly in elevation, of a portion of the door and one of the hinges, showing the means of adjusting the same. Fig. 3 repre- Fig. 4: represents a portion of the door and a sectional view of the end of one of the clampingdogs and a spring-detent by'which it is held when the door is open. Fig. 5 represents an elevation of said dog and detent, taken at right angles to the view shown in Fig. 4. Fig. 6 represents a side elevation of a portion of the bulk-head, a cam-plate secured thereto, and the clamping-do g bearing against said cam-plate. Fig. 7 represents an elevation of a portion of a bulk-head and door, showing one of the clamping-dogs and the cam plate against which one end thereof bears to tighten the'door; and Fig. 8 represents a View, partly in elevation and partly in longitudinal vertical section, of a portion of the door and the clamping devices.

Referring to the drawings, the numeral 1 indicates a portion of one of the bulk-heads of a ship, around the opening of which extends a metallic frame having a flange 2, which is attached to the bulk-head, and a flange 3, at right angles thereto, against which the packing of the door is broughtto bear to secure a water-tight joint when the door is closed and clamped.

The numeral a indicates the door, which is' preferably constructed of metal, as usual, and

which has secured to it by bolts or rivets 5 or otherwise the members 6 of the hinges upon which it swings, the other members 8 of which are fastened to the bulk-head in any suitable manner. The members 8 are each provided with a lug 9, which has an elongated opening through it, and the members 6 are bifurcated at one end, so as to straddle said lugs, and provided with pintles 10, Figs. 2 and 3, which pass through the elongated opening and serve to connect the two members of the hinge. The pintles are headed at one end and at the other are slotted, and through the slots are passed the usual split pins 11 to confine them in place. Through suitable screw-threaded openings in the lugs 9 are passed externallythreaded pins 12, which bear against the pintle and which may be adjustably set in or out to adjust the hinges, so as to give the packing around. the door (to be hereinafter described) a square bearing against the angular flange 3 of the frame surrounding the opening of the bulkhead. At suitable points around the edges the door is provided with clamping devices. (Shown in detail, particularly in the view represented in Fig. 8 of the drawings.)

7 Referring to Fig. 8, the numeral 14 inclicates an externally-threaded sleeve, which passes through an internally-tapped aperture in the door and which is provided with lock IOO or binding-nuts 15, which bear against the door and serve to hold the sleeve against turning when in a properly-adjusted position. Through the sleeve extends a bolt 16, which fits snugly but is adapted to turn freely therein. At suitable points the bolt is annularly grooved, as indicated by the numeral 17, and the grooves are fitted with packing rings of leather or other suitable material to make water-tight joints between the inside of the sleeve and the bolt. The ends of the bolt project beyond the sleeve at each end, and on the outer end is secured, by means of a setserew, feather, or otherwise, one end of alever 18, which sets above a shoulder 19 on the bolt, the shoulder bearing against the flanged outer end of the sleeve before mentioned. The inner end of the bolt passes through an openin g near one end of a dog 20, which is confined thereonby means of a nut 2l, which fits upon the inner .end of the bolt, the same being screw-threaded for the purpose.

The door near its edge is provided with a channel-iron or frame 22, which is provided with an outwardly-flaring continuous recess, in which is cemented or otherwise secured the packing .23, of rubber or other material. The said packing consists of a continuous piece of material rectangular in cross-section and of such width as not to; entirely fill the recess in the channel-iron,-so thatwhen compressed, when the door is closed, against the flange of the angle-frame around the bulkhead opening it will readily expand and bear tightly against said flange.

011 one side of the blllk-rhOfld, at suitable points corresponding to the position of the dogs 20, are located cam-plates 2i, against which. the short arms of the dogs may be brought to bear to draw the door inwardly and press the packing against the flange 3 to make a water-tight joint.

To the one surface of the door, in a suitable position, is secured a series of fastening devices 25, (shown inidetail in Figs. .4 and 5 of the drawings,) which consistof a movable bolt set in a chamber in the device and-pressed normally outward by a spring 26. The outer end of said bolt is recessed, so as to engage the end of the dog 20 when the dooris opened, and hold it in position until. the door is closed.

It will be observed that in the present invention the clamping devices are on the door instead of on the bulk-head framing, which permits said devices to be more conveniently applied and renders it unnecessary to cut or otherwise deface the said framing to apply them.

The operation of my invention is as follows: The door being properly hung upon the hinges, the parts are adjusted so that the packing will bear uniformly upon the flange 3 at all points. \Vhen closed, the pressure is put upon the door by turning the dogs so as to engage the canrpla tes, distcndingthe packing, so as to fill the groove in the channel-iron and make a perfectly water-tight joint.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with the door and the flanged frame secured to the bulkhead, of the channel iron having a flaring groove, and packing secured therein, and mechanism for clamping the door to the bulkhead, substantially as specified, whereby the packin is allowed to expand when compressed.

2. The combination with the bulkhead framing, provided with a flanged frame surrounding the opening, of an adjustable hinged door having adjustable fastening devices, and a channel iron and packing, the said channel iron being formed with an outwardly flaring groove, whereby the packing is allowed to ex pand when compressed, substantially as and for the purpose specified.

The combination with bulkhead door and framing, of an adjustable threaded sleeve extending through a threaded aperture in the door, the an nul arly grooved bolt and packing,

the lever secured to one end of the bolt, and

the dog secured to the other, the am plate secured to the framing, the channel iron and packing, and the flanged f rame against which the packing bears whenthe door is closed, substantially specified.

a. The combination with the pivoted dogs, of the spring fastening devices secured to the door and adapted to en gage and hold the dogs when'the door is open, substantially as specified.

5. The combination with the door and its adjustable hinges, of the fastening devices, consisting of an externally threaded sleeve passing-through the door, the bolt passing through the sleeve and provided with a lever at one end and a dog atthe other, the latter being adapted to engage a cam plate on the bulk-head framing to clamp the door and its packing to its seat, substantially as specified.

(i. A locking dog forbulkhead doors pivoted upon a bolt adjustable laterally withrelation to the door substantially as shown and dc scribed whereby the dog may be adjusted to or from the face of said door.

7. The combination with a bulkhead door, of an adjustable threaded sleeve extending through a threaded aperture in said door, a bolt extending through the sleeve and having secured to one end a locking dog substantially as shown and described, whereby the dog may be adjusted to or from the face of the door.

In testimonywhereof I affix my signz'ii'ure in presence of two witi'lesses.
