l Application inea January 13, 1925.
My invention is an improvement in sash fasteners, and it consists in the combinations, constructions and arrangements herein described and claimed.
An object ot'the invention is `the provi sion in a window having vertically slidable sashes ot' means whereby the sashes will be held releasably in the various positions to which they can be moved without thense ot the usual sash weight, pulley and cord arrangements.
`A further object ot the invention is the provision in a window ot latching means acting automatically to hold the lower sash releasably against vertical movement trom any position to which it has been moved in its slideway and other latching means actto hold the upper sash releasably against vertical movement downward in its slideway,` the latching means be-` ing operable only from the inner side of the Window, whereby the window can not be `ofthe upper sash vand through opened fromthe outer side thereof.
.Other objects and advantages of Vthe `invention, considered in conjunction with the y accompanying drawings, forming a part ot this application, in which Figure 1, is an elevation ot' the inner side of a window, equipped with a practical embodiment ot the invention.
Figure Q, is a horizontal section through the window, the view being taken through the upper rail of the upper sash and through the lowerrail o't' the lower sash. u

Figure 7, is an enlarged horizontal section through the middle kportion of the top rail y the-latch mechanism which is mounted therein. y
lFigure S, is a perspective viewotl a portion of the ratchet'bar tor the upper sash, and
Figure 6, isfa view tace view ot' arportion of the .verse opening 15 trom ving .rocher arms 16 and 17,
the portion thereof which is received within seriai No. 2,205. i
Figure 9, is a view similar to Figure 8, showing a portion ot the ratchet bar for the lower sash.
A window equipped with comprises the usual vertically slidalole upper and lower sashes land 2, respectively. The upper' sash 1 is retained between the vertical the invention side members or stiles 3 ofthe window trame by the usual vertical outer stop strips 4: and the parting strips' 5, the vertical Vedge portions eXtending into vertical guideways which are defined by the outer stop strips L'tand the parting strips 5 in conjunction with the portions ot the side trameinembers 3 which entend between adjacent strips lit--5.
The lower sash 2 has the vertical edge portions thereof received in guidewayswhich are defined by the parting strips 5 in conjunction with inner portions ot the side traine members which extend between adjacent strips 5-6.
The upper sash is the outer sash of the window while the lower sash is the inner sash, as is usual. y
The vertical side barsfofthe lower sash has channels 7 formed in the side 'faces thereof midway between the planes ot vthe outer and inner faces ot the side bars. Each channel extendsltrom the upper end ot the side bar. in which it is formedy nearly to the lower end ot the latter `and then is merged into a deeper channel S which extends for the remainder o't the length of the side bar of the lower sash. The bottom rail of thel lower sash is pi'ovidedwvith channels 9 and 10, respectively, which extend in the bottom stopstrips G andthe tace ot the hottomruil ot the lower sash and are merged at their outer ends into the channels 8 and at their inner ends into a vertically enlarged recess 11 which opens through the bottom wall ot the bottom rail of the lower sash midway oit the length oit said bottoni rail.y A plate 12 is secured by screws 13 to the'inner tace ot the bottom rail ot the lower sash so that a roclr shatt- 111 which is journalled in a central opening in theV plate 12 will extend through aV trans y the inner tace ot' the bottom rail into the-recess 11. 'The rock sha'tt 14 carries a pair `oit oppositely extendrespectively, in
the recess 11, the arm 16 extending obliquely upward from the rock shaft and the arm 17 extending obliquely downward from its ]unc titl ture with the rock shaft. An axially movable latch bolt 18 has an imwardly oli'set inner end portion 19 pivotallv attached at Q0 to the upper' end of the rocker arm 1G and extends in the channel 9 through an opening in a guiding' and retaining' plate 2l which is secured b v screws Q2 against the bottoni wall ot' the channel S at the outer end ot the channel t). it second latch bolt Q3 is pivotallv attached at 2l to the lower end ot' the arm 1T and extends in the channel l() through an opening in a guiding; and retaining plate 25 which secured to the bottom of the channel S at the outer end ol the channel lt). The outer ends ol' the latch bolts 1S and 23 are in sliding contact with the inner faces oi vertical hars 2G which are secured to the iimer t'aces oi'A the side niembers of the window 'traine in position to extend into the channels i', each ol the bars 2G being provided with vertically spaced rockets or notches 2T in its inner tace which the outer end ol the adjacent latch bolt will enter as the low u' sash is slid vertically. the latching bolts being urged continuall)v toward out shot or locking positions bv a tension spring which is disposed in the channel ltl and is attached at one ot its ends to the lower end ol the arm li' and at itsv other 'l to a wall of the channel lt). lt thu:-l will be manifest that the latching' bolts will engage with the sockets or notches 2i' in the bars 26 to hold the lower sash in an v one of a plurality oi' vertically spaced positions and that the lower sash can be moved troni any one ot' such verticall)v spaced positions onlvv when the latch bolts` itl-23 have been withdrawn ironi the particular notches or sock ets 2T with which they were engaged. This is accomplished by manipulation ot a laterally turned handle Q9 which is ric-id with the rock shaft M at the inner `side ol the bottom rail oi the lowei sash and is adapted to be operated nianuallyY to turn the rock sha'l't il so that the arms lG-l will be swung' toward vertical position in the recess ll and the latch bolts 18H23 will be moved axiall'v inward in the channels 5)-10 until the said latch bolts have been withdrawn Vfrom the particular notches or sockets 2T with which the)v were engaged at a given time.
The upper sash also is formed with vertical channels 3() extendingl in the outer 'laces ot' its side rails from the lower ends oit said side rails nearly7 to the upper ends thereof: the channels 3() being mere'ed at their upper ends into relativelY deep channels 3i which extend tor the remainder ot' the length ot the side bars ot the upper sash. Channels 32-33 respectivetv extend in the upper side ot' the top rail ot' the upper sash troni a relatively deep recess 3l to the. upper end portions of the respective channels 31.. The recess 3i also opens through the inner 'lace of the top rail of the upper sash as indicated at 35 for the reception ot a bracket plate Btl havinga marginal i'lange secured to the top rail in eountersunk relation to the inner tace ol' tluI top rail. it rocli shalft il? is ionrnalled in a central hearing '38 l'ornied in the brat-liet plate7 one end portion ol the rochV shalt il? extending into the rece; i while the oppolsite end liortion ol the roel; shalt c \.;tend-1 within the opening 35 hut terminatesl short ol the plane olf thc inner lace ol' tlul top rail ot the upper sash. il. latch bolt Il!) which is siinilar to the latch holt ffii pivolallv attached at its inner cnil to the. upper end otI a rocker arm .ltl which extendsv ohliipielv upward within the recess l-'l l'rom tluA roel: shalt and extends through the ehaune land through an opening in a guiding' and retaiuinl;l platey `rll which is secured lo the bottoni ot the channel ill at thc outer end ol' the channe l. A latch holt l2 which is similar to the latch holt it has a ilo\\ne.'ardl`\.' oilsel inner end portion lll pivotallv at'ached lo the lower end ol a roclfer arm ll which extends ohliquclv downwardlv in the reccs-1 Il! from the rock shalt il? and extends throuffh the channel .U2 and through an opening` inY a c'uidinry and retaining' plate l5 which is secured to the bottoni oil the channel il al the outer end oitE the channel 32. The portion oi the rock shalt 37 that is received within the opening,r carries a handle etti. A tension spring` t7 is attached at one end to the upper end ol" the arm et() and atits opposite end to a wall of the channel 33 and acts` to urge the latch bolts 39ml@ axially outward toward out shot: or locking positions. lVhen the latch bolts 39--t2 are in out shot posi tions, the outer ends thereof are in contact with teeth -l8 on the inner faces ot vertical ratchet bars e9 which are secured to the inner faces of the side members of the window traine in position to extend into the channels 30. Each tooth 48 has a horizontal upper face and a sloping)r or inclined lower tace and the latching bolts 39 and ft2 have the outer end portions thereot lormcd as shown to engage with the tlat upper sides of corresponding teeth to prevent downward movement ot the upper sash until the handle 1lb has been manipulated to cause axial inward movement ot the latch bolts 39 and 112. l'l'owever. when the upper .sash has been moved downward lroni closed or raised position, it' can he returned toward closed or raised position without there being any neces` sit7 ot operating' the handle t3 to retract the latch bolts since the latch bolts will slide along the inclined lower laces ot the teeth 48.
Frein the foregoing it will be obvious that in v invention provides a window havincr vertically adjustable sashes which will beheld in vertically adjusted positions without the use of sash rope, pulleys and weights, and that the window cannot be opened trom the outer side unless the latching mechanism Itri! llo lill) ri c Withvvhich it is provided is broken. A Win dow of ordinary construction can be equipped with the invention at slight cost and Without any extensive changes in the usual construction of such Window.
Obviously the invent-ion is susceptible of embodiment in forms other than that which is illustrated in the accompanying drawings and I therefore consider as my own all such modifications and adaptations thereof as fairly fall Within the scope of the appended claims.
