ALPHONSE A. SEBASTIAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO ANDREW HOFFMAN MFG. 00., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

CASEMENT-WINDOW.

Application filed June 25, 1919.

To all whom it may concern:

Be it known that I, ALrHoNsn A. Snsas- TIAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Casement-VVindows, of which the following is a specification.

My invention has for its principal objects the provision of a sliding or casement window embodying certain structural features which make for efficiency in weather exclusion, ease of operation, sightliness, economy of construction, and accessibility for adjustment and repair or renewal of parts, concealment of hardware fittings, proof against binding due to settling of building, automatic adaptation of same to inequalities of casings, and capacity for installation in an ordinary boX window frame without the remodeling or the substitution of a special frame as is ordinarily required where a casement is substituted for double-hung windowsu These objects are attained, in general, (1st} by providing an upper suspending or guiding channel having vertlcal dimensions over all not exceeding the depth of the usual recess in the head between the parting strip and the stop, whereby 11o forming of a special groove in the head is required for the housing of the channel; (2nd) by suspending or grinding the hinged sash members from the channel by means of hanger brackets which are attached to the edge of the sash instead of the side face or the upper edge thereof, thus rendering the fastening screws readily accessible by partially opening the sash, as distinguished from the difficulty of access to such screws when the brackets are attached to the upper edge and especially when the top of the sash is close to the ceiling, and also entirely concealing the hardware fittings from view when the window is in closed position as distinguished from the undesirably conspicuous fittings where attached to the side face of the sash; (3rd) by providing a guiding connection between the ends of the sash and the track or guide, which connecting medium has a vertically adjustable and pivotal relation to the sash as well as provision for horizontal play, whereby continuity of and free engagement with the track is in no wise jeopardized by irregularities of vertical or horizontal dimensions of the opening, as when the upper Specification of Letters Patent.

Serial No. 306,602.

suspending track and the lower guiding track one or both sag, buckle or otherwise deviate from parallel right lines.

Other distinctive advantages of the new construction will be readily apparent to persons acquainted with the practical require ments of sliding window construction and the disadvantageous features of the prior art.

WVhile the present invention is illustrated and described as applied in a folding casement window composed of hinged units suspended from above, it will be obvious that it is also applicable to sliding windows composed of independent units, as also to folding and sliding doors; wherefore the accom panying drawing and the detailed description predicated thereon are to be taken in an illustrative and not in an unnecessarily limiting sense, reference being had to the claims as a measure of the scope of the invention.

In the drawings, a preferred embodiment of the invention in a casement window is illustrated, wherein s Figure 1 is a horizontal section through a casement window;

Fig. 2 is a transverse vertical section on an enlarged scale illustrating the invention as applied to a standard box window opening, such section being taken on the line of Fig. 3;

Flg. 8 is a front elevation of Fig. 2;

Fig. l is a fragmentary detail in perspective of the upper guiding track or channel;

Fig. 5 is a similar view of the hanging bracket;

Fig. 6 is a similar view of the pivot plate;

Fig. 7 is a similarview of the lower guiding block;

Fig. 8 is a fragmentary detail in perspective of a portion of the lower guiding track;

Fig. 9 is a fragmentary elevation of the window operating handle Fig. 10 is a detail of said handle; and

Fig. 11 is a fragmentary detail showing a slight modification of the sill fitting.

Having reference to Fig. 1 of the drawings, the left hand end of said figure represents a substantially medial longitudinal section through a casement window of the present invention while the right hand side of said figure representsa top plan view of a pair of the sash immediately below the lintel, the observer being on the outside of the window. At the right hand of said'figure the dotted lines indicate the position of the two sash when partly open. In said figure the window j amb isrepresented at 11, the sill at 12, a window screen at 13, and the window frame generally at 14. The inner pulley stile is shown as replaced by a filler strip 15 and the outer pulley stile as supplied with a filler strip 16. The parting strlp 17 forms the outer stop between which and the filler strip 15 seats the stile 18 of the easement window. The window in this figure is shown as composed of four sliding units 19 hingedly connected 'together by hinges 2O at their adjacent edges in pairs, the adjacent stiles 21 of the two pairs arranged to abut when in the closed position of the window, the line of juncture being covered by the astragal 22 or, the adjacent stiles 21 may be hinged together in the same manner as are the units of the two pairs by hinges 20.

In Figs.;2 and 3 the same construction is shown modified only to the extent necessary to show the adaptation of the invention to the mounting of the casement window in the standard box frame used in connection with double hung or doublesliding windows. Here the head of the window frame is repre sented at 23 and the sill at2t, the former provided on the inside with the stop 25 and the latter with the stop 26. Vhere it is desired to equip such standard window frame with the sliding or casement window of the present invention, the guide channel 27 is placed within the recess in the lower face of the head originally provided for the accommodation of the upper ends of the sliding sash. This guide channel being of limited vertical dimension is entirely received within said, recess without the necessity of forming a special groove or seat therefor. The guide channel held in position within the recess by'means of the screws 28 has its lower face substantially flush with the lower face ofthehead or slightly above the same. Th'efiller strip 29 is then placed in position between the said guide channel and the standard. parting strip 30 although this filler strip 29 may be omitted. A filler strip 31 is then preferably placed in the recess provided in the'lower face of. the head for the upper end of the outer sash so as to give an upper finish to the window opening. This filler strip 31 may beadvantageously'supplied with a drip groove to prevent moisture traveling inward along the filler strip. A finishing stop 25, previously referred to, provides additional security againstthc entrance 3 of the elements althoughit is not absolutely, necessary; The

upper guide 'channel27, as best shown in 'F1g.-4:,- has its side walls lnturned along theirlower'ed'ges, said edges being arranged to oppose each'other at a slight.v distance apart as indicatedat 33 (Figut) so as to constitute of said channel a guide housing provided along the lower face with the slot 34 between the edges 33.. The guide channel 27 is arranged to accommodate the rollers 35 which rollers are rotatably mount ed upon the spindle 36 which is fixed in the arm 37 of an L-shaped bracket 38, the other arm 39 of which extends at right angles to the arm 37 and is provided at 40 with screw holes for attachment by means of the screws 41 to the edge ofthe sash. The spindle 36 has sufiicient length between the plate 37 and the roller 35 to allow for the edges 33 of the guide channel the spindle itself being accommodated within the slot at.

Upon the sill 2d of the window frame is secured a sill plate 42, upwardly flanged along its inner edge as indicated at as to provide a guiding rib for the lower edge of the sash. This rib 43 is spaced slightly outward from the sill stool andthe aforementioned stop 26. Upon the lower edge of the sash adjacent its outer edge is secured a pivot plate at having an upturned positioning flange 45 to engage the outer edge of the sash. This pivot plate carries a pivot t6 downwardly projecting. Upon this pivot 46 is loosely mounted an elongated guide block 47 by meansof an aperture 48 which engages over the pivot pin 46 whereby to permit a rotary pivotal movement of the pin with reference to the block and also a relative axial or vertical movement of the block on said pin. The lower face of the block is grooved at one side of the pivot as indicated at 49, said groove arranged to re lower corners of the sash one directly above the other, the axis of the pivot pin 46 corresponding substantially with that of the roller spindle 36, the. opposite edge of the sash being hinged at 20 to the corresponding edge of the next adjacent sash unit of the pair so that'as the two rollers 35 of thepair are moved toward each other the continuity of the pair of sash willbe broken at the hinge as indicated in dotted lines at the right hand end of Fig. 1, thus permitting the windows to open. At the hinged edges of the sash; is provided a handle 50'pivoted on the leaf 52. for attachment by means of the screw holes 53 to the edge of the sash intermediate the regular hinges, this form of construction being illustrated in'de tailinl ig. 10. r i

'An explanationlof the 'methodgof installing the window of the present application will make clear many of its advantages over previously devised constructions. The suspending channel 27 and the sill plate 42 having been placed in position at the top and bottom respectively of the window opening, after the requisite number of hangers 38 have been associated with the channel 27, their rollers being within the same, two of the closure units are connected together at their adjacent edges by means of the hinges 20 and the handles 50 are placed in position. One of the hinged pairs of sash memhers is then positioned at the bottom with its guide block 47 taking over the rib 43 and with its pivot pin 46 in the opening 48. The pair of sash is then brought to a vertical position with the upper edge of each embraced between the arms 37 and 39 of one bracket 38. WVhen properly positioned a line is drawn around the arm 39 of the bracket and a proper mortise prepared for the reception of the said arm 39 to render the same flush with the edge of the sash. The screws 41 are then driven home and the mounting of the sash unit is completed. The casement window is now completely installed. It will be observed that the mounting of all the hardware fittings is accomplished without having to work from the confined space above the sash and that when the windows are closed the hanging brackets are entirely concealed from View, the only hardware visible being the butts of the hinges and the handle 50 provided for the operation of the sash. It will likewise be observed that when the windows are wholly or partially opened, the brackets are exposed to view and the screws 41 accessible in the event it is desired to remove any one of the sash for replacement or repair. The provision for vertical play of the pivot pin 46 in the hole 48 of the block 47 insures that said block may travel back and forth along the guide rib 43 without any danger of disengagement therefrom even though said guide may be sagged in the central portion, the said block remaining in constant relation to the guide and the pivot pin 46 playing up and down within the hole 48 to take care of any variations in vertical dimensions of the space separating the suspending channel 27 and the sill plate 42. This vertical play taken in connection with the pivotal mounting of the elongated block 47 on the pivot pin 46 and the off-set disposition of the groove insures against binding or disassociation of the parts.

It will be observed that I have provided a sliding casement window which is especially adapted for ready association with the standard window frames without requiring the taking out of the same and the substitution of a special frame for the purpose; that the hardware fittings are concealed from view except when the window is open, and are readily accessible to the workman when mounting and dismounting the sash; that binding and all danger of disassociation of the parts is avoided by the provision for vertical, pivotal and lateral play between the sash and the guiding block 47, rendering the window practically immune from difficulties arising after installation to which windows of this type have been peculiarly susceptible.

l/Vhere, as show in Fig. 11, the flange of the sill plate 42 underlies the stool 26, the installation is advantageously accomplished by placing the required number of blocks 47 in position on the plate with their grooves 49 over the flange 43 and the sill plate is then shoved with the blocks beneath the overhanging edge of the stool, after which the sill plate is fixed in position by means of the screws. In this form of construction, the overhang of the stool provides an additional safeguard against accidental disengagement of the block from the guiding rib where the sill may have sagged in any portion of its length.
