VERTICALLY-SLIDAIBLE INWARDLY SWINGING WINDOW.

Application filed April 27,1925; Serial No. 26,010.

To all whom it may concern:

Be it known that I, OWEN L. DAUTRICK, acitizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Vertically-Slidable Inwardly Swinging Windows, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an attachment for vertically slidable window sash, whereby the sash may be swung inwardly for cleaning the outer face of the glass and that it may also be inclined and secured rigidly for ventilating purposes, as shown in the accompanying drawings and more particularly described in the following specification and claims. 7

It is well known that in large ofiices or apartment buildings the problem of cleaning windows is one involving considerableannual expense due to the time required and hazardous nature of the work.

It is also well known that when vertically movable windows are raised for ventillation that the current of air passin directly through the opening creates a draft which is unpleasant and may cause occupants of the room to suffer from colds.

The primary object of the present invention is to provide an attachment forvertically movable window sash whereby the glass may be quickly and readily cleaned from the inside of the building, thereby greatly reducing the risk incurred by the party cleaning the windows and time required to do thework. A further object of the invention is to provide means whereby the window sash may be tilted and secured at any desired angle for ventilating purposes in order that a1r currents may be directed upwardly above the heads of occupants of the room.

A further object of the invention is to provide suitable metallic guides attached to the window casing coordinating with elements carried upon the edge of the sash to facilitate the ready vertical movement of the latter, thus overcoming any tendency to bind a d al o to teams a dose j in harvest the window casing and the sash frame to prevent the entry of drafts common to the ordinary wood sash and easing.

A further object of the invention is to provide detachable means adapted to be connected with the sash frame and casing to sup-v port one of the sash frames in an approximately horizontal position for cleaning and upon which the other sash frame may rest when cleaning the latter.

A-further object of the invention is to provide means whereby the sash frame may be automatically locked when swung into alignment with the vertically slidable members to which it is pivoted, and which coordinates with the member secured to the window casing.

A further object of the invention is to provide means whereby the sash may be readily removed from the window casing when re quired to make repairs-there being no stop head to remove or replace.

With the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes maybe made in the precise embodiment of the invention herein disclosed without departing from the spiritof the same. In the drawings accompanying this specification:

Figure 1 is a perspective view showing both sections of the window sash lowered and tilted inwardly in a horizontal positionthe lower sash being supported by suitable detachable bracket arms connected with the casingthe upper sash restin on the lower sash frame-the dotted lines indicating the sash frames tilted and secured at an angle for ventilating purposes.

Figure 2 is a fragmentary perspective view with parts broken away and in sec-. tion, showing the lower sash frame supported in a horizontal position to a vert cally slidable member to which it is pivoted-showing also in dotted lines one of the hooks engaging a pivot pin carried by the vertically slidable member which when disconnected therefrom permits the removal at the sh has the ad a "f detachabl'y g g ng the were the channel showing a fragment of a detachable bar for supporting the sash in a horizontal position Figure 6 is a cross-sectional view through one of the sash rails and. a fragment ofthe wind-ow casingtaken on or about line 66 of Figure -2the sash'how'ever being a.

Figure 7 is a fragmentary elevation ofthe vertically slidable element supported in the window casing and the swinging element detachably pivoted to the vertically slidable element by a swinging latch hook carried by the swinging projecting from. the vertically slidable element-the latch hook being raised-as when removing the sash-not shown:the view' also shows a fragment of a detachable bar for supporting the sash in a horizontal position-the parts attached to the sash being raised to free it from a weather-strip secured to the sill that the sash frame may be swung horizontally for cleaning the glass. Referring now to the letters of reference placed upon the drawings bers of which are secured L-shaped sheet metal strips B spaced from the edge of the frame by a relatively narrow interlaying strip' C, one side for securi'ngthe L-shaped and interlaying thereby providing a groove C at strip to the sash rail.

D designates the stile of a window easing to which is nailed or otherwise secured an L-shaped strip Eits outer projecting edge E extending between return bends of a vertically slidable sheet metal member F, ofchannel-like form. .One of the channel walls of the member F. is provided with an L-shaped return bend with one of its flanges f spaced from the back of the channel that it may slide in the groove C, between the L-shaped member B and the edge of the sash rail. p I

G denotes a flat spring secured by a gromi met g-to the channel member F, fitted with a Wedge-shaped detent G, designed to enter a slot B in the L-shaped strip B,the reby element engaging a pin denotes a'sash frameto the side mem-' of the sash rail. B indicates screws' hooks M member. To provide for readily detaching the channel member F from locked relation with the L-shaped m'emberB, the chancord hook H at its upper end secured to of the channel member F h, by grommetsor eyelets, thus prothe inner wall at h, viding at its upper end an aperture to receive the studs of a supporting bar I, engagedat its lower end with the sash, through an opening provided in ber B.

The bars I, are designed to support the sash frame in an inwardly directed horizontal position, whereby the outer face of the glass inside ofa room.

- Secured to the hook H at the' upper end of the plate H, is the-usual sash cord J, in turn attached to the usual sash weightnot shownfor dow.

K denotes a spring actuated hook which is adapted to engage screws the pockets formed by the channel members-the purpose being to lock the verticall; slidable members F and B against the liftmg action ofthe sashweights when the sash 1s swung into a horizontal position as indicated in Figure 2for cleaning.

Carried by the spring latch K and pro-.

jecting through an arc-shaped slot in the channel member. F is a pin K which is adapted to be acted upon by the end wallof a slotted recess B formed in the L-shaped strips Bthe strip upon contact- K out of locking relation withthe screw L when the sash is returned to its normal the L-shaped mom-- may be readily cleaned from the L projecting from thestiles D of the window easing into y p yr counterbalanc'ing the winmg with the pin K serves to.- force the latch vertical positionin alignment with the channel members F.

Pivoted to the L-shaped members B at the lower end of the sash are swinging hooks M adapted to engage a pin F projecting from the wall of the channel memher at and detaching the supporting. bars I, the sashmay be readilyremoved from the window casing forrepairs, without the necessity of removing or replacing the usual stop beads.

N denotes an upwardly projecting sheet metal weather strip secured to the sill adapted to enter a slot-not shown-provided in the lower .edge'of the sash and corresponding with the slot F at the lower end of the channel member.

'Vifiheait is to gthe sash into.

its lower end. By releasing the' junction with the aperture formed by vthe grommets g, connecting the spring .latch with the channel member F-are designed w to receive studs projecting from each end of a relatively short pair of supporting bars P, to maintain the sash at an angle for ventilating purposesas indicated in dotted lines in Figure 1.

ing members of the upper sash are similar to those of the lower sash, and it is not considered necessary to duplicate either the drawings or description of same to convey W a complete understanding of the invention.

the glass, the spring latches are released Having now indicated the several partsby reference letters the construction and operation of the device will be readily understood.

The sash when in normal position is in alignment with the vertically slidable channel members F, and is secured thereto by the spring latches G, carried by the channel member entering the. slots B in ,the rL-shaped strips B, secured to the edges of the sash.

When it is desired to swing the sash into a horizontal position-as indicated in Figure 2for cleaning the outer surface of by pressure upon the upper ends of the springs G. The sash is then swung inwardly to the position shown, whereupon the latches Kdue to the action of their springsengage the screws L, projecting from the window casings into the space provided between the walls of the channel members. The channel: members F are thus held against upward movement due to action. of the counterweights. M The supporting bars I, with theirprojecting studs at each end, are now engaged through the apertures provided in the re" spective channel members F, and L-shaped bars B, secured to the edges of the window sash- To clean-the outer face of the ,upper sash, the latter is lowered and swung inwardly, the respective latches 1K of the upper sash engaging screws L, as in the case of the lower sash. The upper sash however rests directly upon the lower s ash, as indicatedin Figure 1., without the n i of additional supporting bars I.

If it is necessary to remove the sash from the vertically slidable channel members F It will be understood that the coordinat-,

The sash may then be removed from the window casing.

Upon returning the sash to its normal vertical position the supporting bars I, I, are first removed and the sash swung into alignment with the channel members-the end wall of the recess B in the L-shaped strips B forcing the pins K of the spring controlled latches K out of engagement with the screws L-the spring latches G simultaneously entering the slot B in the strips B,

thereby automatically locking the sash in icertical alignment with the channel members If it is desired to tilt the windows at an angle for ventilating purposes a pair of relatively short supporting bars P fitted at each end with studs are employed to connect the upper ends of the sash with the channel member by inserting the studs in the respective apertures provided to receive.

-them"the sash isthus supported at an angle so as to direct the air currents upwardly to avoid drafts.

It will be apparent that the angle or L- shaped strips'E, secured to the stile of the window casing serves not only as a guide for the channel members F but insures a tight joint between the parts.

Having thus described my invention what I claim is: i

1. -In a device of the class described, a

pair ofvertically movable channel members provided with horizontally projecting pivot studs, a vertically slidable sash provided with metal strips secured to the sash and having bearing recesses receiving the pivot studs and a pa r of swinging hooks provided with recesses intersecting the recesses of the said strips and receiving the pivot studs for confining the said pivot studs in the recesses of the said strips.

2. In a device of the class described, a pair of vertically movable channel strips provided adjacent their lower ends with horizontally projectinghead studs,-a vertically movable sash provided at its side edges with sheet metal strips extending longitudinally of the sash and provided at their lower ends with vertical recesses extending upwardly from the lower edges of the said strips and receiving the said studs, a ,pair of laterally swinging hooks pivoted to the sash and provided with recesses arranged to intersect the recesses of the said strips and receiving the studs to confine the latter in the said recesses.

3. in a device of the class described, a pair of vertically movable channel members, a

sash pivoted to the channel members and adapted. to swing inwardly therefrom and means for automatically locking the channel members against upward movement when the sash is swung inwardly, said means comprising, a horizontal pin-fixed with relation to the vertically movable'members and a spring actuated catch arranged vertically and pivoted at its upper endand having its lower end beveled and provided with a recess for engaging the said fixed pin, and a projection carried by the catch and extending into 'the path of the sash and arranged to be engaged by the same whereby the catch is disengagedfrom the pin when the sash is returned to its normal vertical position. 10

In testimony whereof, I sign this specification. i
