7 Claims. l

This invention relates to sliding windows, and has Vfor its object to provide a sliding window assemblage, more particularly, but of course, not exclusively, for use on shipboard, the window whereof may be readily raised or lowered by means of hand. pressure alone, is automatically rendered watertight after movement without the aid oi extraneous hand screws, or the like, and which, being of simple and robust construction, is relatively cheap to produce.

According to our invention, a sliding windowv assemblage comprises a frame `adapted for tting to a window aperture, and a counterbalanced sheet of glass or other appropriate material (hereinafter, for convenience of reference only, designated glass) associated with said frame and adapted to be raised or lowered by hand into and out of aperture-closing position, and said assemblage being characterised in that the combined weight of said glass and the means where by it is counterbalanced is utilized to effect, auto matically, the watertight seating or sealing and locking of said glass (after movement thereof) against the adjacent frame or frame portion. Our invention is further characterised in that seating or sealing and locking of said glass may be effected in any position of vertical adjust'- ment in which the glass may be placed.

in one embodiment, our invention comprises a frame to each side whereof is pivotally secured, by means of t'wo or more parallel links or shackles, a vertical housing; a pair of rack bars slidably located in each housing and in opposed engage ment with a pinion positioned therebetween and rotatably journalled in said housing; and a sheet of glass secured adjacent its edges to a rack bar of each housing, the co-operating rack bars being provided with individual balance weights, or alternatively a single weight common to both.

One or more oi the links or shackles is or are provided with a toothed quadrant in engagement with a hand-operable pinion, whereby the vglass and counterbalancing mechanism is pivoted about said shackles away from the frame to permit ready adjustment of said window by hand.

We will further describe our invention with the aid of the accompanying sheets of eiiplaiiartory drawings which illustrate, by lway of ex'- ample only, and not of limitation, one inode of embodying same.

In said drawings, in which like characters of reference denote like parts wherever they occur,

Fig. 1 is a front elevation of a window assemblage suitable for Ause `on shipboard,

Fig. 2 is a side elevation,

Fig. 3 is a section drawn to an enlarged scale as compared with the preceding views, taken as on line A-A, Fig. l,

Fig. 4 is a section of a rack bar housing, taken as on line B-B, Fig. 2, and drawn to an enlarged scale as compared with Fig. 3; and

Fig. 5 is a fragmentary elevation in part section.

Referring now to said drawings, I denotes a metal frame with securing bolt holes 2 and a spigot portion 3 adapted to enter the Window aperture ci a ships plating. Pivoted at each side of frame I on pins il, 4 are two connecting links 5, 5X which carry at their outer ends, means of cranked pins t, t, a vertical housing t; said cranked pins 6, 6 permit adjustment of the eiective length of links 5, 5x. Pins t are adjustably located at one end within bifurcated end portions 5e of links 5, tx by means of screws 5b, and. are provided with medial ats Kia whereby they may be turned to required positions of adjustment with the aid of an appropriate spanner. Links, 5, 5X are therefore capable oi being readily adjusted to permit the iitting of glass, and/'or resilient seating therefore, of various thicknesses. The other ends oi said pins ii are revolubly located in apertures provided for their reception in housing l', and thus said housing l is permitted a limited amount of arcuate movement at the end of links 5, 5X, and conse quently toward, or away from frame i, while maintaining its parallel relationship therewith.

Slide-bly located within each housing l are a pair of rack-bars t, it in opposed engagement with a pinion li free to rotate about a spindle I2 on ball races I3, I3. Said spindle i2 is secured within housing 'i by means of an enlarged head portion ia and a screw i213. A sheet of glass it, provided with ahandle I5, is secured in any convenient manner to rack bars 9, and a weight 8 is bolted to the lower extremities of co-operating rack bars lil, i5 in order to counterbalance the weight of rack bars 9, S! and attached glass I4. The rack-bar housings 'l andthe pinions ll are preferably formed of Bakalised linen, or synthetic resin board, in order that the movement may be self -lubrica'ting The two lower links 5X, 5X are each provided with a toothed quandrant Yand in operative engagement with Said quadrants are pinions I6, Iii, keyed to a shaft Il journalled in side brackets la, la of frame I. The length of shaft li may be adjusted by means of a pin-and-slee've joint I8.

One end I'Ia of shaft I'I is entered into a gear ture closing position.

box I9 secured to a bracket extension I b of frame I, and secured thereto is a bevel wheel 20 arranged to mesh with a pinion 2l secured to a spindle 22 which, being disposed at right angles to shaft Il, is journalled at each end in bushings I9EL screwed into the sides of gear box i9. An end 22a of spindle 22 projects exteriorly of gear box I9 and is adapted to be engaged by a handle 23 whereby pinion 2i, bevel wheel 2t, and so shaft Il is rotated. Other types of gearing may, of course, be utilized in place ci that described, and may be disposed on either side of frame I as desired: in some instances gearing may be omitted and suitable toggle or other linkage substituted therefor, or, handle 23 may be secured directly to shaft Il.

Normally, the combined weight of the counterbalanced assembly carried at the ends of links X, 5, 5X, causes glass it to bear against a sealing strip 2li of rubber, or other suitable resilient material, which is fitted around the window aperture of frame l, and, when the glass is ina lowered position, against vertical rubber seating strips 25 secured to frame I below the window aperture. Thus, an all round watertight joint is attained between glass and frame when the window is closed i. e. when glass le is in its uppermost position; and when said glass is partially or fully lowered, a watertight joint is still maintained between said glass and the adjacent portions of sealing strip 211;.

The abutment of glass It against strips 2e and 25 effectively prevents the raising or lowering of said glass until the assembly carried by links 5, 5X, 5, 5X is pivoted upward and so away from frame I. This latter operation is achieved by turning the handle 23 (as indicated by arrow in Fig. l) when pinions I 5 on shaft il are rotated to move toothed quadrants 5, 5C of links 5K, x upward. Housings l', l are thus pivoted upwards and glass it moves clear of sealing strips 24 and 25, and while in this latter state the position of glass Ill in relation to the window aperture may be readily changed by appropriate nnger-tip pressure on handle I5.

When frame I is fitted to a ships platingbeing secured thereto in watertight manner by bolts passed through apertures 2-the weight of housings 7, "l, and associated parts being supported by links 5, 5X, 5, 5X, causes the glass It (assuming it to be in its uppermost position) to press firmly against the rubber sealing strip 2i., thus forming a watertight joint and erectively sealing the window aperture, and automatically locking the glass in position. If it is desired to open the window, handle 23 is turned, thus rotating-through pinion 2! bevel wheel 25.3 and shaft i-the two co-acting pinions I5, which cooperate with quadrants 5 of links 5X to move glass Ill out of sealing abutment with strip 2li. It is to be noted that when released handle 23 will automatically return to its original position, and-by reason of the weight of housings l and associated parts acting on quadrants 5 and so pinions IB--the glass ld is locked in its new position.

To limit the upward travel of glass Id a rubber or other stop 26 is secured adjacent to the top of frame I as illustrated, and to limit upward movement of weight 8 and so downward movement of glass It, a rubber stop 2 is provided on the upper edge of the weight 8. Strips 25 positioned on either side of frame I ensure a parallel seating for glass I4 when it is in other than aper- With the object of preventing water passing between housing 'I and the adjacent sides of frame I when the window is partially or fully opened, angle strips 28 are secured-as by screws 22S-around the perimeter of frame I, and which strips are adapted to guide water seepage, into a conventional drip tray (not shown) fitted below the window and so outboard of the ship.

As said hand-lever is positioned on the inside of the window, unauthorized opening of same from the outside cannot be effected.

In an alternative method of securing the window assembly to the main frame, the pivotal shackles may be replaced by upwardly inclined and slotted members immovably secured to said main frame. Appropriately spaced pins fitted on either side of the rack and pinion housings are entered in said slots, and the inclinations thereof and the weight of the window and control mechanism effect the required water-tightness of the window.

The clearance necessary to raise or lower the window may be obtained in this instance, say, by lever-actuated cams adapted to urge the assembly upward, and therefore away, from the sealing material.

in a further embodiment, the rack and pinion gearing may be replaced by double-cut right and left hand screw-threaded rods of coarse pitch which cause a balancing weight or weights associated with nuts working on said rod to be moved in a direction opposite to that of the window as the latter is raised or lowered.

It will be apparent that windows constructed according to our invention may be utilized with advantage in all circumstances where sliding windows are required, and that the construction and arrangement of component parts may be varied without departing from the scope of the invention.
