VERTICALLY-SLIDABLE INWARDLY-SWINGING WINDOW.

Application led July 5,

T o all 'whom z't may concern.'

Be it known that I, OWEN L. DAUTRICK, a citizen ofthe United Statcsresiding at Detroit, county of l/Vayne, State of VMichigan, have invented a certain new and useful Improvement in Vertically-Slidable Inwardly-Swinging indows'` and declare the following to bea full, clear, and exact de scription 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 convenience in cleaning the outer face of the glass, as shown in the accompanying drawings and more particularly described in the 'following specification and claims. i It is well known that inv large otlice or apartment buildings the problem of cleaning windows is one involving considerable an nual expense due to the time required and the hazardous nature of the work.

The primary object, therefore, of the present invention is to provide an attachment for vertically movable window sash whereby the glass may be quickly and readily cleaned from the inside of thebuilding, thereby greatly reducing the risk incurred by the party cleaning the windows and the time required to do the work. c

A further object of the invention is to provide suitable metallic guides attached to the window casings adapted to co-act with elements'carried upon the edge of the sash in order that the vertical movement of the sash may be facilitated and whereby the tendency and casing.

to bind, common to ordinary sash in which two wood surfaces lie in contiguous relation 'is overcome.

A further object of the invention is to provide a close fitting overlapping construction thereby preventing the entry of drafts incident to the use of the ordinary wood sash .embodiment of the invention herein dis- 1924. Serial No. 724,316.

closed without departing from the spirit of the same.

ln the drawings accompanying this speciication: A

Figurel is a fragmentary front elevation of a slidable channel member adapted for attachment to the usual sash cord connected with the lower detachable. end of said slidable channel member.

Figure 2 is a longitudinal sectional r)view taken on 'or about line 2--2 of Figure l showing the lower sash frame pivoted to the detachable end of the slidable channel member; the detachable end of the channel member being engaged by a latch carried by the body portion of said member. l.

Figure 3 is an enlarged4 view of an upper fragment of the channel member shown in Figpre 1, engaged to the loop of a sash cor Figure 4 is a' longitudinal sectional view through the slidable channel member, taken 0n or about line 4 4 of Figure 3,-connected with a sash cord.

Figure 5 is a cross-sectional View of the slidable channel member, and a co-acting guide or track plate secured to the window casingthe winldow casing and sash frame being shown in dotted lines.

Figure 6 is a fragmentary perspective View of one of the slidable channel members with parts broken away showing a fragment of the sash frame pivoted to the lower detachable end of the channel member.

Figure 7 is a fragmentary perspective view with parts broken away and in section showing the lower sash swung into locked alignment with the slidable channel member that it may move vertically therewith.

Figure 8 is a fragmentary perspective view showing the lower sash swung intoy a room for cleaning, and the upper sash and channel frame-to which the latter is pivoted, lowered that it may be swung below the ends ofthe detachable slidable channel members of the 'lower sash,-indicated by the dotted lines, the full lines showing the upper vsash vand upper channel members raised in order that the upper sash may tilt over the detachable lower end portions of the channel members supporting the lower sash, as it would appear when about to be laidl upon the lower sash.

Referring now to the letters of reference placed upon the drawings:

A denotes a lower sash frame to the side members of which are secured plates A pivoted at Aa to a relatively short channel member B carrying an upwardly projecting tongue Bb having a beveled end Bbb projecting into a. relatively long vertically movable abutting channel member C, that the detachable channel member B may be held in locked relation with the latter by a spring latch D, fitted with a stud Dd adapted to enter an aperture b1 provided in the tongue B1 riveted or otherwise secured te said lower detachable channel cmember/ B.

Projecting -inwardly from the channel member C is a tongue C1 adapted to receive :11.1 loop E attached to a weighted sash cord Pivoted to the upper end of the channel member C is a spring actuated latch F adapted to engage a latch plate G secured to the side members of the sash frame near their upper ends to lock the sash in alignment with the vertically` movable channel member. C2 indicates a second tongue struck up from the body of the vertically movable channel member C and extending laterally to overlap the latch plate G to assist t-he latch F in maintaining the sash in proper alignment with the vertically movable channel members z-the side members of the sash frame being cnt away to permit the tongue to pass beneath the latch plate as indicated at Figure A2.

H designates a guide rail secured to the side members of the window casing having iianged edges HHHa in spaced relation to the window casing to receive the inwardly directed edges Ca of the channel member C, forming a draft-tight joint with the flange ll of the guide rail. The channel member C is also provided with a projecting flange Cb adaptedto overlap the side member of the sash frame against which the sash is tightly held by the spring latches F.

Having now indicated the several parts by reference letters the construction and operation of the device will be readily understood:

lVhen it is desired to swing the lower sash inwardly to clean the outside of the glass,

the sash if raised is first lowered. the latches l" pivoted to the slidable channel members are then released to permit the lower sash to swing inwardly on the pivots A, projecting from the lower detachable channel members B, whereupon the outer face of the glass may be readily cleaned 'from the inside ot the building.

To clean the upper sash the channel members CC of the lower sash are first disconnected from the Ilower detachable channel members BB by releasing the stud Dd carried by the spring latches D from the apertures b1 in the tongues Bb.. The channel members CC are then lifted under Athe action of their respective counterpoised weights to the position indicated in Figure S. The upper sash is then lowered until it touches the sill-as indicated in dotted lines in said figure. The sash is then released from the control of the spring latches Fx, that it (the sash) may swing below the vertically Inovable channel members CC, as indicated in dotted lines in the figure. The upper sash is then raised slightly to the position shown in full lines in order that it may swing over thcl lower detachable channel member B",-

whereupon it may be lowered so as to rest. upon the lower sash that the outside of the glass may be readily cleaned.

After cleaning the windows the upper sash' is swung back into .its initialposition in alignment with the upper movable. channel members CXCx slidable on the guide rails Ilxthe sash being secured in alignment by the spring latches F". It will be understood that the construction of the channel members and cooperating parts of the upper sash are substantially similar to those of the lower sash.

Thechannel members CC of the lower sash are. then lowered into locking engagement' with the detachable lower ends B. The lower sash is then swung-back into its initial position in its channel members` to which it is again locked by the spring latches F. The sash frames are then in condition for operation as usual, or until the windows are to be cleaned again.

Having thus described my invention what I claim is:
