SIIDABLE WINDOW R THE LIKE Application led September 7, 192,9, Serial No. 390,972, and` in Great Britain September-15, 1928.

This invention relates to Vslidable'windows or the like, particularl but not exclusively for use on ships and has special reference to the type of slidable window wherein a glass holder is adapted to be slidably moved in a fixed frame by hand operated gearing and is provided with projections or cams that enable it to be moved away from its seating in the fixed frame so that it can then be slidably moved without friction and its seating face which is usually provided with a rubber ring that can be pressed against the fixed frame to provide a water-tightjoint. A

The chief object of the present invention is to simplify the construction of the slidable window and to enable the glass to be readily removed from the glass holder in the case of breakage f'orfinstance, and replaced Without completely dismantling the window. A

According to this invention the fixed frame is provided projections on the slidable glass holder which at its inner part or face is provided with means, for example, projections or cams such as those aforesaid, to enable the glass holder to be moved and held away from its seating when it is slidably moved. The said projection or cams which engage with recesses or 30 grooves on the inner face of fixed frame when the window is closed, may be provided on a retaining ring, which in conjunction with a flange on the glass holder serves to retain the glass in the holder. When it is desired to open the window, for example by operating gearing such as that aforesaid, the

glass holder, as. it tends to be drawn downA` wardly, is first moved away from its seating by the projections or cams engaging with bevelled or curved ends of the said recesses or grooves and after the projections or cams have moved out ofthe recesses they bear against the inner faces of the fixed frame and thus maintain the glass holder with its.

rubber seating ring out of engagement with the seating in the fixed' fra-me, at the same time providing a metal to metal contact which facilitates the sliding movement of the glass-holder. The said retaining ring maybe secured to the glass holder in a readily dewith side grooves to receive lateral tachable manner so that after removing the same, the glass can be quickly taken out of the glass holder.

In order that the said invention may be clearly understood and readily carried into eect, the same will now be described more fully with reference to the accompanying drawings, in which Figure l is a front view of one construction of the improved sliding window for use on ships. j Y

Figures 7 and 8 are enlarged fragmentary side views showing the glass holder in the positions shown in Figures 5 and 6.

Figures 9 and 10 are enlarged cross sectional views also showing the glass holder in the positions shown in Figures 5 and 6.

A represents the main or fixed frame which may befof any usual or suitable construction and which is provided with side' grooves A1 in the. part that receives the glass holder. B represents the glass holder which is provided at its sides with projections B1 that are disposed in the l"aforesaid side grooves A1 in the frame A. The glass plate B2 is retained in the glass holder against a flange B3 by means of a retaining ring C whichis detachably secured fto the glass holder by anumber of screws C1 (see Figures l and 2) andwhich extends beyond the inner face or sides of `the fixed rame as shown. VAround the outer surface of the glass holder a rubber seating rin `D is provided and this'V is. adapted to ie. pressed against a seating face A2 on the fixed frame so as to make a water-tight closure, by means of retaining screws E that are mounted in lugs Ellandare adapted to bear on the inner surface of the glass holder. f The construction is such that limited movement.V of

the glass holder B with its seating ring D towards andaway from the seating A2 on the frame A is permitted. The retaining ring C extends outwardly beyond the glass holder and the extending portions are provided with a number of projections or cams F whichrfit in recesses' or grooves G in the sides of the fixed'frame when the glass holder is in the. closed position, the projections or cams being such that they can be moved out of the recesses or grooves G when the glass holder is moved away from its seating A2 in the fixed frame. At the lower part of the frame A gearing is provided for slidably moving the glass holder, which latter is loosely connected by a pin and slot H to a nut or block I threaded on a main operating screw J that can be rotated by hand operated bevel gearing K. In order to enable the sliding window to be opened, the aforesaid retaining screws E are first manipulated to release the pressure on the glass holder B and the rubber seating ring D. The main operating screw'J isthen rotated by the bevel gearing K so as to cause the nut or block I to be axially moved. Owing to the projections or cams F on the retaining ring C of the glass holder, engaging with bevelled or rounded surfaces at the lower ends of the aforesaid recesses or grooves C they are positively moved out of the recesses so asv to travel on the inner faces of the sides of the fixed frame. This movement results in the rubber seating ring D being moved definitely out of Contact with the seating A2 on the fixedframe to eliminate friction so that the sliding movement of theglass holder can be effected whilst it is maintained in this position by the projections or cams engaging with the inner faces of the fixed frame, and providing a metal to metal contact that facilitates the sliding movement. The glass holder ma be secured in any desired open position lily means of the aforesaid retaining screws E bearing against the outer surface of the retaining ring so as to clamp the glass holder against the fixed frame. When it is desired to close the window the aforesaid gearing is operated in the reverse direction in order to raise the glass holder, which on being fully raised can be pressed by the retaining screws E so that its rubber seating ring bears against the seating A2 in the fixed frame, this being permitted by the projection of cams F fitting in the recesses or grooves G. In order to enable the glass to be taken out of the glass holder, it is merely necessaryl to remove or displace the lugs El carrying the retaining screws E and to take off the retaining ringV after unscrewing the screws C1 thus leaving the glass free to be removed. A new glass plate can then be placed in the glass holder and held ytherein by screwing the retaining frame into position, whereupon the lugs E1 carrying the retaining screws E can be positioned for enabling the latter to bear on the glass holder as required.

What I claim and desire to secure by Let- 1 ters Patent of the United States is 1. A slidable window of the type referred to, comprising a fixed frame having interior side grooves, a glass holder having lateral flanges fitted to slide in said grooves, means for slidably moving the holder in said grooves, and projectionson the holder cooperating with the fixed frame while moving thereover, as the holderl slides in the grooves, for positively moving the holder away from the fixed frame.

2. A slidable window of the type referred to, comprising a xed frame having interior side grooves, a glass holder having lateral flanges fitting in said grooves, means for slidably moving the holder in the grooves of the fixed frame, a retaining rim on the holder for holding a glass in position therein, said rim extending laterally beyond the sides of the holder and having means projecting from one face and engaging inboard surfaces of the fixed frame while moving thereover during said sliding movement, to positively move the holder from the fixed frame.

3. A slidable window of the type referred to, comprising a fixed frame having interior .side grooves, a glass holder fitting in said grooves, a rubber seating ring between the glass holder and said frame, means for slidably moving the holder in said grooves, and cam members on said holder cooperating with recessed walls of the grooves of the fixed frame to force the holder away from the frame and relieve the pressure on the rubber seating ring as said holder slides in the frame.
