"It is one of the objects of the invention to provide an improved arrangement of parts by the use of which the leading edge of the closure member upon an opening operation is given first an oblique movement edgewise and outwardly away from the window frame so as .to cut down to a minimum the frictional engagement of the movable .closure member on the stationary frame parts. In the preferred construction, the closure member is provided with weatherestrips along its side edges in position to engage suitable portions of the window frame assembly, the are rangement being such that the oblique movement of the closure member at the start of .opening operation carries the Weather-strips out of position for operative engagement with the frame so that the closure member moves easily and smoothly and the wear on the weather-strips is kept to a minimum. In the arrangementasillustrated, W ther-strips are provided both .alon the side edges of the closure member and along the side bars of the window frame, one of such sets of weather-strips being inchannel ortgroove form so as to receive a rib or tongue portion of the cooperating strip therein :for making a tight joint at each edge of the closure :member. In this arrangement, the oblique movement of the closuremember at the start of the opening operation is particularly helpful, since 1it;assu r es the benefit of a highly effective joint when the window is closed while at thesame time permitting the closure member to be moved easily out prove arrangements of this type in sundry ,de-

tails hereinafter pointed out. The preferred means by which the severalobjects have been attained are illustrated in the accompanying drawings and are hereinafter ;specifically described. That which Ibelieve to. be new; and de sire to cover by this application :is set forth in the claims.

For.closin :thewiudow-oneni aa p eceofnl-ate lass 32-9 i employed provided-se its lower :edge

mounted on the rods 26. Just above the collars 34, other collars 35 are slidably mounted on the rods 25, coiled springs 35 being interposed between the collars for holding the collars 35 normally raised to the limit of their motion with respect to the collars 34. Links 31 are pivotally connected at their forward ends with the collars 35 and at their rear ends with the downward extension 3|, the pivotal connection with said extension being effected by means comprising lugs 38. The arrangement is such that when the collars 35 are moved downwardly toward the collars 34 from the position shown in Fig. 4 to the position shown in Fig. 2, the downward exten-, p

sion 3| and the plate glass 29 connected therewith are moved backwardly toward the right in;

said figures.

As is best shown in Fig. 2, the lower edge of the plate glass 29 is provided with a rubber gasket 39 which is secured in position by screws 40 taking into a cross bar 4|. The arrangement is such that when the plate glass is moved to the upward limit of its motion the gasket 39 has tight engagement with the frame bar I9 so as to seal the joint between the glass and the bar.

The means for moving the glass 29 upwardly. and downwardly with respect to the frame bar l5 comprises a spiral pinion 42, fixedly connected with the screw 28 and meshing with a spiral gear 43 fixedly connected with a spur pinion 44 which in turn meshes with a spur gear 45 driven by a crank handle 46 positioned at the front face of the housing 23. When the gear 45 is driven by means of the crank, the screw 28 is rotated, serving to move upwardly or downwardly a nut 41 having a threaded connection with the screw, the direction of movement of-the nut depending of course upon the direction of rotation of the 1 wardly toward the right in Fig. 2 for bringing the gasket 39 into sealing engagement with the bar I9 at the end of the upwardmovement of the glass. -When the glass thereafter is moved downwardly again by a reverse rotation of the screw 28, the springs 36 insure thatthe links 31 shall be biased to the limit of their motion as soon as the pressure on the collars 35 is relieved so as to cause the downward extension 3| and the glass definitely to move forwardly for carrying the gasket 39 out of engagement with th bar I9.

' The means for sealing the Window at its upper edge comprises a strip of sponge rubber 49 held in position by a sheet metal member 59. At opposite sides of the window, the side bars I1 and I8' are provided with channel members 5| opening inwardly, with a grooved sealing member 52 mounted at one side of each of the channels in position for engagement with a cooperativesealing'member 53 mounted on the glass in the form :7

of a rib or tongue. In the arrangement shown, the grooved sealing member is formed largely of felt, while the ribbed member 53 is bent. into form from sheet metal so as to grip the edge of ,the glass for presentation of the rib effectively to the groove. In the construction illustrated, the upper end portion of the front flange portion 54 of each of the channel members 5| is obliquely disposed so as to cooperate with the links 31 for moving the glass backwardly toward the frame member l5 when the glass approaches the upper limit of its movement.

By the use of my improvements, I have provided a highly useful arrangement. When the window is closed, the opening is completely sealed so as to prevent the entrance of water, for example, when employed in connection with a boat. I he weather strips are arranged so as to resist a high degree of pressure without danger of any water seeping through any of the joints about the closure member. When, however, the closure member is moved edgewise out of closure position, the closure member is given an initial movement facewise for carrying the weatherstrips out of engagement with each other so as to permit easy movement of the closure member and so as to keep to a minimum the wear and tear on the weather-strips and the operating parts.

While I prefer to employ the form and arrangement of parts as shown by the drawings and as above described, my invention is not to be limited to such arrangement except so far as the claims may be so limited, it being understood that changes might well be made in the form and arrangement of the parts without departing from the spirit of the invention.-
