Be it known that l, Fnunnniolt CHARLES (lonnon, n citizen ot the lhiited Stategand a resident oft lll-lesttield, in the county of Union and Stute ot' New Jersey,l have invented a new and Improved llieather-Strip, ot which the following` is a full. clear, and exa'ct description.

This invention relates to weather strips tor use with windows and which muy also be used with doors. Prior to this invention many types ot weather strips were devised. The ordinary telt or rubber' strip beers on the sash makingl it ditiicult to open 4the window and causing rapid wear ot' ,both sash and strip. During damp went-her window sashes swell and it a rubber weatherstrip is used the sashes are likely to jam and nre operated only with great diliiculty, while in dry weather when .the sashes shrink the window not tight enough to keep out the wint. Some strips are objectionable on account ot the cost ol installation; others are unsatisfactory under certain weather conditions, Jfor instance, weather strips mounted on the outside ot windows otten freeze together in winter and prevent the opening ot the window; and many due to their construction continually get out of order duringl use.

The object of this invention is the provision oit a. simpleand durable weather strip that may be easily fitted on windows during; the construction otl the buildingfand that may be readily mounted on the windows oil any building;` alter construction to malte the windows practically airtight when closed but which permits them to open freely. p

Another object is to provide u weather strip that is not` prominent and presents a good appearance.

These objects are zuifcomplished by provid ing in conjunction with the lower window sash.y zt curved plate which engages with a bevel tace on the stool und serves to torce the sush against the parting stop. and mounting a narrow curved plate on the upper sash which contacts with a projection in the window casing' and forces the upper sash against the parting; stop, and means tor drawingthe lower portion oit the upper sash against the upper portion ot the lower sash.

These and other objects will be more clearly understood trom the following detalled description and accompanying` drawings.

Ateft-frringr to the al:ove-nientionerl figures, a window easing l() `has u stool li und a sill l2. ll/lounted in the sides and top ot the casingl() ere pai-tint` stops 13, Fitted into the casing' and held in position b v the stops two' sashes. an upper sash ls und a lower sash l5. letes ot 1G arc litted into the snshes and held in position by putty 1T.

Fixed to the lower .slush a spring metal plete .i8 which is pretcraibly inside ot brass but may be mede ot some other flexible materiel. This plate is somethini` the slinpe ot the letter S with the upper portion straightened, and it is this upper portion that lits against the sash sind ias'i'enci'i thereto by means ot nails or screws t9. 'The plete 1S extends across the window and bears against a bevel tace :'20 which muy' he cut in the stool 1l when the strip is bein;v installed during the construction ot the building.

The plate lil is so located ou tht` sash that the curved portion beurs against the bevel face 20, thus forcingl the sash :Against the parting` stop L23 when the window is closed. It the weather strip to be appliedv to u window after the building has been constructed it is more satis ectory to suppl): e strip 2l which has a bevel 'tace E22 and mount this strip on the stool ll. 'lhc plate 'i8 is then So located on the lower sash that it bears against the bevel 'tace 22 when the window is shut.

Mounted on the upper sash by inea-ns ot screws 24 is e plate 23 of similar cross section to the plate'lS but only a couple ot inches in length. This plate engages a screw 25 which is lixcd in the upper part of the casing and serves to Jforce the upper sash against the parting stop. A lock 26, which may be ot any ordinary type is provided to draw the upper part ot the lower sash and the lower part ot the upper sash together.

A modification ot the spring plate 18 is shown in Figure 8, in which case the upper straightened part ot the S-shaped spring plate is bent to continue the lines ot the upper part of the lower portion of the S, thus forming a spring plate a section of which resembles cane. In order to mount this spring plate on the window the straightened portion is driven into the sash and the curved portion co-operates with the bevel tace on the stool to torce the sash into contact with the parting stop. A number ot other modifications of this spring plate might be made. It is also possible to change the position of the spring plate and mount it on a `stool so that it co-oper ates withv the window sash to torce the sash into contact with the parting stop. In the case of the upper sash the narrow spring plate might be mounted on the window frame and the screw 25 litted in the sash.

' When the window is closed, the metal spring plate engages with the bevel face of the stool or on a strip fastened to the stool, and forces the sash against the parting stop. The spring plate on the upper sash or frame engages with the screw or other projection and forces the upper sash against the parting` stop. The lock mounted on the lower sash is then engaged with the catch on the upper sash and serves to draw the upper and the lower sashes together thus forming a practically air-tight window which may be easily opened as soon as the lock is disengaged.
