Y
The window of the present invention, indicated generally by the reference numeral- I, includes a main window section -2, which in the presen-t embodiment is the lower section. This section, in the present embodiment, is similar to the window structure shown in the Rohman et al. Patent No. 1,962,328, June 12, 1934, except as modified in accordance with the present invention to pro- .vide for an upper section or transom il.V `it will be understood that the type of window of the patent has been chosen for use with the transom of the present invention merely because it lends itself readily to such adaptation, but it is contemplated that other types of windows may also be employed if desired, and other uses made of the window than as a ship window. y
The window structure is shown disposed in a deck house Vl of a ship. The deck house bulkhead ..5 is provided with an opening in which ts the lower part of a stationary window casing 6 for the window lower section, and the deck house roof 'l is provided with an opening l(a continuation of the bulkhead open-` ing), in which ts the upper part of the casing l, forming a frame for the upper window section or transom 3. The lower part of the casing is vertical and consists of a bottom horizontal member 8 and side members 9. The upper part of the casing or transom frame is inclined inwardly oi the deck house and consists of a top horizontal member Hl' and oblique side members H secured vat their bottom endsv tothe top ends of the side members 9. The casing 6 is built up forming a unitary' rigid structure.
The bottom member 8 consists of a horizontally extending flat bar l2 parallel to and secured to the bulkhead, a flange i3 extending out'- ward over the lower edge of Ythe bulkhead opening andA a larger grooved iiange ld extending inwardly toward the window section 2, in the groove of which is disposed a resilient rubber sealing member I5 against which the window section 2 is pressed when the window is in closed position. Y
Each side member 9 consists of a verticallyextending flat portion liV parallel to and-se'- cured to the bulkhead. A flange l1 extends outwardly from one side of the portion I6 over the adjacent edge of the bulkhead opening and a longer flange IBAextends inwardly toward the Window section 2. The inner end of the flange I8 is enlarged and provided with a wedge-shaped groove I9 in which is disposed a resilient rubber Other screws 23, but having their heads countersunk, secure the members 8 to to the deckv house. e
The iiange 2| is provided with three inclined slots 24, the slots slanting in an outward direcf tion from bottom to top. Each of the slots isprovided with a removable wedge member 25. Each wedge member includes an oblongplate 26 which is disposed on the deck house side of its respective flange 2| Vand secured thereto by screws 2'l and a slanting wedge piece 28 integrally formed on the side of the plate 26 engaging the iiange 2| and fitting into andextending through the yslot 24 for a purpose later to be described.
The members I3 and |'l of the transom'frainel are made of thev same frame section and therefore a description of onefside memberV as shown in'Fig. 5 alone will bevgiven. The'memf ber Il consists of parts 29, 39, 3|, 32;33, 34 and which are similar respectively. tothe parts I6 to 22 ofY themembers 9. The 'flange 3| is, however, longer than the flange .I8 as the transom 3 is spaced from the portion zfurther than the windowsection 2 is spacedfrom the portion I6.
There are three locking members indicated generally bythe reference numeral 36, secured to the transom frame, one on each side `and one at the top thereof. VEach has a body portion 31 seating on the strip 35. An operating handle 38 extends in one direction from the body portion and a finger 39 extends from the'body portion at right angles to the-handle. The body portion has an unthreadedoriiice 40 in line with a smaller' unthreaded oricer4| vformed in thestrip 35, a shoulder. 42 being formed bythe portion of the strip .extending from the periphery of the orince 4| to the peripheryof the orice 40. A boss 43 -isl formed integrallyfwith orwelded on the flange 34 opposite each body portion 31. and each boss contains athreaded orifice 44 in line with and thesame 'sizetas' the adjacent `orifice 4|. .A screw 45 secures the body portion tothe strip 35,- the screw having a head 46 engaging the inner side of the body portion, an'unthreadedrportion 41 extending through'the orice`40 and a smaller threaded portion 48 extending through the orifice 4| and screwed into the threaded orifice 44'. A
shoulder 49 is provided on the screw 4between the unthre'adedpportion K41'and the smaller threaded portion 48 and this shoulder 49 fits againstthe shoulder 42,. As the Unthreaded portion yl|`| is slightly longer than the unthreaded orifice 40 the body portion has workingclearance between the head 46 and thestrip 35 and can be turned readily from operative to inoperative position.
The window section 2 consists of a pane of glass 50 held within a frame 5| consisting of a tie bary or bottom member 52, top'member 53 and ,side members 54. The bottom member is merelyv a bar extending between and fastened to the side aaieyeo secured to the inner side lof themember 54 and a groove 59 facing in an opposite direction from `the channel 56 is formed adjacent the outer side of the member 54, the rack 58 and groove 59 being for a purpose later to be mentioned.
The top member 53 consists of a body portion Swhich contains Va channel 6| in which is disposed a rubberchannel 62 which firmly holds the upper edge of the pane 50. The upper face of the member 53 r'zontains a groove 63 in which is disposed a resilient rubber sealing member 64. Three spaced hinge lugs 65 are formed on the inner top portion of the member l53 Vfor av purpose later to be desc1ib`ed.`"f Y The upper section o'r transom 3`consists of a pane ofglass GGheldwithin a frame 6l fconsi'sting-of a topmember |i ,fbottom member -69 and side members-'HLy The sideand top members are made 'of simple channelirons, in the channels of which are disposed rubberchannels"||"securely holding the adjacent=`edges ofthe pane 66.*- On the ,centerof the inner side of -the side and'top members, at points adjacent thev locking members 36,.are formed or secured wedge vmembers 12 providingcam surfaces for a purposeiater towbe described.A The bottomV member Sii-consists ofv a members and engaging the Ibottom edge of the pane 50. It may of course, if desired, be channelchannelled body portion 13 :in the 'channel' of which is disposed a rubber channel14 securely holding the bottom edge of the'pane 65. f .Three spaced pairs of hinge members '|5 extend downwardly from the inner bottomfportion of the bottom member 69, one at each side'of each `lug to cooperate therewith tohinge `the transomto the window section 2 for swinging movement` relativeithereto. The hinge lugssand members are connected together by pins |6`. The bottom member-|9 also has a portion v'l'lwhich-functions to seal the, joint between the transom and section 2. Thisportion 11, describing'it whenthe tran` som is closed (the section-2 being then in its raised closed position), consists of a-rounded outwardly and downwardly extending memberxlS and a hor# izontal member 79 which extends/outwardly from the bottomof vthe member v'|8.' The member 19 is pressed against the resilient rubber sealing member 64 `when the transom isin closed position sothat no water or'airi. can leak through the joint between the'transom andsection 2. v'A portion of each `hingememberl 'l5 is formed by the` rounded member 'I8 and I each hingei'member -15 is strengthened by a reinforcing flange 80 `which' is connected at its .upperLend to the body-,portion '13, at its inner edge tothe member '18, andat its lower edge to the member '19.` s
The windowA comprises aV mechanism,:r indicated generally by the reference'numeral-'SL-for positively raising and lowering the window, and a window lateral movement mechanism indicated generally by the reference, numeral 82. v They are enclosed within acommonyhousing 83 Which'exf tends completelyacross thewidthof the window adjacent the bottom part thereof when-the win-y dow is fully raised. A sheet of vmetal 84 depends from lthe bottom of the. housing and, together-l with the housing, both of which arepspaeed from the inner side of the bmkheadg' form a pocket a5 in which the window section 2 and transom are disposed when in full lowered (window open) position.
The window raising and lowering mechanism comprises a horizontal shaft 86 extending longitudinally of the housing 83 and supported thereby by bearings 81- secured to the inner face of the housing. A worm wheel 83 is secured on the shaft and meshes with a worm. 89 formed on a shaft 90 which extends at right angles to the shaft 86 and extends through the housing 83 into the interior of the deck house. An operating handle 9| is secured to the inner end of the shaft 99. On either end of the shaft 86 is secured a pinion 92 in mesh with the lower end of the adjacent rack 58 when window section 2 is closed. By rotating the handle 9| in one direction or another, the window is raised or lowered by the operation of the pinions 92 and racks 58.
The window lateral movement mechanism 82 comprises a shaft 93 above and parallel to the shaft 86, within the housing 83 and supported thereby by bearings 81 similar to the bearings 81. A handle 94 is secured to the shaft 93 and extends through the wall of the housing into the interior of the deck house. At each end of the shaft 93 is secured a gear segment 95 in mesh with an inclined toothed rack 96. Each rack 96 is inclined downwardly and inwardly and each segment 95 increases radially upwardly in order to permit coaction between the teeth of the segments and teeth of the racks.
The racks 96 are formed on vertical wedge bars 91, one of which is disposed at each side of the window section 2 between the adjacent flange 2| and side member 54. Each bar 91 has three inclined slots 98, each opposite one of the slots 24 and in each of which is disposed a wedge piece 28. A nange 99 extends from the outer side `of the bar 91 at right angles thereto into the groove 59 thereby co-nnecting the bars 91 each with the adjacent side member 54. The strip 22 encloses both the member 54 and bar 91.
The operation of the window lateral movement mechanism is as follows. When .the window is in its full upper position and it is desired to press the window section 2 against the sealing member 20, the handle 94 is pushed downward, which moves the racks 96 upward and outward, forcing the bars 91 upward and because of the wedge pieces 28, outward. Movement of the bars 91 outward is accompanied by outward movement of the members 54 because of the flange and groove connection therebetween, thereby forcing the window section 2 into tight engagement with the sealing member 20.
When the window section 2 is in full upper position and it is desired to lock the transom, the lock members 36 (the transom rst being closed) are each turned so that each iinger 39 engages the cam surface of the adjacent wedge member 12, forcing the transom into tight engagement with the sealing members 33 and 6A, the transom frame abutting the transom.
The advantages of the present invention are apparent from the foregoing description. With the window section 2 and transom in full raised position and forced into engagement with their respective rubber sealing members by the members 36 and mechanism 82, no water or air can enter the deck house from the exterior. Added overhead or Vertical visibility is afforded from the interior'of the deck house, due to the inclined transom. The transom can be lowered to a position abreast of the window section 2 without disturbing the window in any way or it may be moved to some partially open position (when the Window section is closed), as indicated in dot and dash lines in Fig. 2, and held Vthere by any suitable means such as a chain (not shown). Furthermore, the window section 2 and transom can be lowered, when the transom is abreast of the window section 2, to any desired position between full upper and full lowered window position and held in this position by the worms 88 and 89. Finally the transom may be moved to an out-of-the-way position in the pocket with the window section 2 when full window opening is desired.
It will be obvious that the increased overhead View attained by means of the inclined transom is important in modern day ship building, especially in the case of war vessels where visibility is necessary in order to sight air-planes passing overhead. However, the invention is not limited to an inclined transom for, from various aspects thereof, it may be applied to a vertical transom hinged to a vertically slidable window section.
While there has been hereinbefore described an approved embodiment of this invention, it will be understood that many and various fchanges and modifications in form, arrangement of parts and details of construction thereof may be made without departing from the spirit of the invention and that all such changes and modifications as fall within the scope of the appended claim are contemplated as a part of this invention.
The invention claimed and desired to be secured by Letters Patent is:
A window for a ship deck bulkhead and roof, each having an opening providing respectively for outward horizontal and vertical skyward vision, said openings being adjacent and in alignment, said window comprising a fixed lower frame for said bulkhead opening extending downwardly therebelow at the inboard side of said bulkhead; a lower sash slidahly engaged by said frame, in closed position when raised adjacent said bulkhead opening, and in open position when lowered opposite said bulkhead; a xed upper frame for said roof opening having its bottom adjacent the top of said lower frame and extending in an inboard direction therefrom; an upper sash hinged at its lower edge to the top edge of said lower sash, swingable about said hinge in an inboard direction to a position abreast of said lower sash whereby both said sashes will be opposite said bulkhead below said lower opening when said lower sash is in lowered window-open position, providing a clear View through said openings horizontally and skyward, said upper sash being swingable against said upper frame to closed position when said lower sash i-s in its said closed position; and releasable means for holding said sashes closed.
