ESCAPE SCUTTLE Filed May s1, 194e Patented July 19, 1949 ESCAPE SCUTTLE Donald G. Wilson, Stratford, Conn., assignor The Wilson Manufacturing Company, Stratford, Conn., a partnership Application May 31, 1946, Serial No. 673,576

3 Claims. (Cl. 292-55) This invention relates to a quick opening escape scuttle to be used in water-tight doors or similar devices of ships and the like, and more particularly to a scuttle which may be opened from either side of the door, and has for its oblject to provide a simply operated means through which a person trapped behind a jammed watertight door or hatch could escape.

It has for its further object to provide an eslcape means which may be operated from either I have devised the construction illustrated in the accompanying drawing forming a part of this specification.V It is, however, to be understood the invention is not limited to the specic'details of construction and arrangement shown, but may embody various changes and modications within the scope of the invention.

' In the drawing:

Fig. 1 is a front elevation of an escape scuttle embodying my invention with a portion of the outer hand wheel thereof removed to show a detail;

Fig. 2 is a section taken substantially on line 2?-2 of Fig. 1, showing one clamp only, and

Fig. 3 is a section showing in detail a portion vof the device.

The invention as shown comprises a substantially circular shaped cover or lid assembly Il). vconstructed of any suitable material, preferably steel plate, clamped by a suitable means to a water-tight door II, or bulkhead, deck, or other wall, so that it covers a substantially circular opening I2 in said door or wall II'.

The cover or lid assembly I consists of a substantially circular flat cover or plate I3, provided at its edge with a rim bar or flange I4 fastened by a suitable means, such as welding, at substantially right angles to and circumscribing the plate I3. A second rim or flange I5 similar in construction to the rim vI 4 is fastened to the plate .I3 by a suitable means, such as welding, so that it is within and concentric to the rim I4. The rims I4 and I5 confine a Water-tight gasket I6 ,composed of rubber or other suitable material. v The circular opening I'2 is completely enclosed by a coamingor rim I'I, secured in place by welding I8 to the door, the opening being of such size that the edge of the coaming I1 will contact the rubber gasket I6, when the cover assembly III is vplaced to cover the opening I2. Thus, when the cover assembly I0 is clamped or held in this position by some suitable means, the coaming II will press into the rubber gasket I6 held in place by the retaining rims I4 and I5, forming a watertight Seal.

A suitable means for clamping the cover assembly Ill in the closed position heretofore described consists of a bushing I9 through the cover I'3 at substantially its center, and secured there by a suitable means such as welding 20. A series of ribs 2I, preferably three, are also welded to the bushing and to the cover I3 along its radii, terminating at and welded to the rim I5. These ribs 2| provide additional supporting means for the bushing I9 as well as provide stiffening to the cover I3 to prevent buckling and the like.

The bushing I9 supports a spindle or arbor 22, so that this spindle 22 may turnfreely in the bushing I9. A flange 23 on-the spindle 22 and a wheel 24 with a substantially square hole 25 at its center, which flts on a similarly shaped portion of the spindle 22, and which is held on the spindle 22 by a nut 26 threaded to the spindle 22, prevent the spindle 22 from moving longitudinally of the bushing I9. The wheel 24 and the flange 23 are separated from contact with the bushing I9 by washers 21 and 2B. A second wheel 29 is attached to the opposite end of the spindle 22 from the wheel 24 by means of a substantially square hole 30 which fits on a similarly shaped lportion of the spindle 22 and is vretained on the spindle by means of a nut 3|.

It is clear that because both

wheels

24 and 29 are attached to the spindle 22 by means of substantially square holes at their centers, and since the spindle 22 is free to turn in the bushing I9, either or both

wheels

24 and 29 may be turned by an operator to turn the spindle 22. Bronze bearing bushings I9a for the spindle or arbor 22 may be mounted in the bushing I'9 and separated by a suitable packing |911 to provide a Water-tight bearing.

The portion of the spindle between the flange 23 and the wheel 29 is threaded to receive a nut or traveler 32. The nut or traveler 32 is shaped to receive a ring member 33 which is held to the traveler by being clamped between a shoulder 34 on the traveler and a lock nut 35 threaded to the traveler and secured thereto by peening over the edge 36 of the .traveler 32.

A series of forked members or arms 31, preferably three, is fastened to the ring 33 by a suitable means, such as welding, and extends radially from the ring. The outer end of each of the members 37 is forked, as shown at 31a, to receive the end of a dog 38 in the form of a lever which is pivoted to the forked member 3'! by means of a nut and bolt assembly 39 through holes in the fork of member 31, and a longitudinal slot 40 in the dog 38. This dog is also pivoted between a pair of lugs 42, welded to the inner side of the cover I3, by means of a nut and bolt assembly 4I through the lugs'or ears 42 and the dog 38. Y

It is clear that when the

wheels

24 and 29 are turned, the nut or traveler 34 Vandthe forked members 31 attached thereto will travel longitudinally of the spindle 22, thus causing each Adog 38 to swing about the pivot 4 I, the inner end of the dog 38 pivoted to the bolt assembly 39 being slotted as shown at 40 to permit this end .of the dog 38 to swing in an arc. The other end 43 of the dog 38 also swings in an arc about its pivot 4I, the dog 38 being of such length that when it is swung to the locked or closed position, shown by dotted lines, Fig. 2, by means of turning the

wheels

24 or 29, the end 43 will press against the coaming I'I at the side opposite the cover I0, thus clamping the coaming I1 securely between the gasket I6 and the dog 38, causing the coaming II to press into the gasket forming a water-tight seal between the door II and the cover assembly I0. When the

wheels

24 or 29 are rotated in the opposite direction, the traveler will move along the slot to the other extreme position, shown by solid lines, Fig. 2, causing the end 43 of the dog 3B to swing in an arc about its pivot 4I, thereby leaving the coaming and pulling inwardly toward the center, permitting the end 43 of the dog 38 to clear the inside wall 44 of the coaming I1, allowing an operator to swing the cover I6 open.

The cover I3 is hinged to the door II by means of a pair of hinges 35, so that it may be swung to the open or closed position. The hinges comprise a hinge blade 45 fastened to the outer surface of the lid I3 by a suitable means, such as welding, and pivoted, by means of a nut and bolt 4 by inserting the toggle pin 53 through the

lugs

50 and 49, permitting the toggle 54 to assume a -position substantially perpendicular to the pin 53, thus preventing inadvertent removal. The scuttle may be closed by simply reversing the above outlined procedure.

It can be seen that I have constructed an escape scuttle which, through its simplicity, offers a maximum of reliability, and by being operable from either side of a door or wall to which it is attached provides a maximum of utility.

Having thus set forth the nature of my inven- Y .tion, I claim;

assembly 48, between two lugs or hinge pads llI4 l.

welded to the door Il.

A suitable means for holding the cover Aassembly I3 in the open position consists of a pair of lugs 49 welded to the door or wall II and spaced to receive a lug or blade 59 welded to the cover I3. A hole 5I is soplaced in the lug 50 that it will be aligned with holes 52 in the lugs 49. A toggle pin 53 provided with a pivoted toggle ythe closed position; that is, the cover assembly It covers the opening I2, as heretofore described.

The cover may be opened by an operator turning either

wheel

24 or 29, causing the traveler 34 to move longitudinally of the spindle 22. In this manner the dog 33 is caused to swing onits pivot 4|, thus causing the end 43 of the dog 38 to swing away from the coamingl'l in an arc, toward the center, thus permitting-.the cover to be swung open. The cover is heldin the open position 1.
