Application filed December 12. 1914. Serial No. 8.76,790.

To all whom t may concerm- Be it known that I, ALVAR K. TERNSTEDT, a subject of the King of Sweden, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanically-Operated Windows, of which the following is a specification. This invention relates to a construction 1G or means whereby a frameless plate of glass in a mechanically operated window may be quickly .and easily replaced when broken.

The object of the invention is to avoid the necessity of removing or disturbing the window operating mechanism in order tov get at the broken glass to remove and replace it. It is also the object to effect this result in a simple and practical manner. The invention consists in the improved construction and arrangement for accomplishing the desired result hereinafter more particularly described and then specified in the claims.

'Ihe invention will be herein shown and described as applied to a carriage window such as employed in automobiles in which the window is raised and lowered by mechanical means in contradistinction to the 40 door or wall in which the window is located.

In the accompanying drawings, F igure'l' is a vertical, central cross-section through a carriage wlndow construction 1n accordance with this invention, the same being shown as applied tothe door of an automobile.

Fig. 2 is a front elevation of the same, the

inside upholstery being removed to show vthe operating'mcchanism more clearly.

Fig. 3 is a transverse section through one `of the side pillars, the glass being removed. Fig. 4 is aview similar to Fig. 1 showing the parts in position for removing and re'- placing the glass.'

Fig. 5 is a perspective view of the lower part of the glass plate with the detachable plate for the operating mechanism connected thereto.

Fig. 6 'is a front elevationiof part-'vof the lower casing showing the operating means after being detached from the glass.

Fig. 7 is al vertical central cross-section through the door, the glassaand its operating mechanism being removed to show the ar. -rangement of the guiding channelsy (one side) in which the glass travels.

In the drawings, l indicates the outer weather rails, 2 the inner rail or top board of the lower casing 3 in which the operating vmeans are mounted. 4 indicates the head rail' ofthe door and 5 indicatesthe side pillars of the window. o ening.

6 indicates a plate of) glass formingthe closure. for the space between the head rail 4, weather rail 1 and pillars 5, the closure in this caso being of the framelcss glass type, that is, 'the glass plate is not surrounded by the usual'inclosing frame but its side edges.

are preferably rounded and work in velvet or. otherwise suitably lined guides formed in or attached to the pillars 5, the -linings for the guides, for clearness, not being shown in the drawings. According to this invention the guides are referably 'formed as U-shaped channels?. X guiding channel is provided for each side of the glass, but one being shown in the drawings. The guides run from directly beneath thehead rail 4 down into the casing 3 and are each divided intopreferably two parts, the upper par' 7 being of a length somewhat short of the height of the glass plate 6 and a space 8 is left betweenit and the beginning of the lower guide 7 (see Fig. 7 for purposes to be hereinafter described. Obviously, as

the glass 6 is caused to travel it will straddle the space 8. Thr guides 7 and 7 are suitably secured to the pillars 5, the upper part 7 being preferably fastened by means of lugs` 9 integral with or secured to the channel 7 and attached to the pillar by suitable screws. The upper end of the guide 7 enters a recess l() in the head rail 4 while the lower4 end is preferably concealedl beneath the up# peredge of the top board 2. y

The lower edge 'of the .glass plate 6 in a. U-shaped 'carrier 11 which is provided seats at or'about it's center with a short length of mounted within the lower casing 3 and is provided with` a plate 14 secured to the top board 2 so that itsupper edge will be posi tioned somewhat down from the upper edge of the opening 13, the object being to leave the openingl exposed. The plate 14 carvries and supports the upper part of the operating means, the lower part being suitably supported near the bottom of the `casing 3. Any suitable type of operating means may be employed but preferably l use the brief reference to the parts herein kis sufliplication type shown and described in my prior` aprialfhlo. 666,759, and it is thought that a cientA as the particular type of means employed. forms no part of my present inven` se;

tion.

A sprocket-wheel 15 mounted at the back of the plate 14 is provided with an operat- Sii.

ing handle 16 which projects beyond the inner face of the door. A casing 17 secured to the front of the plate 14 contains the automatic locking mechanism which holds the glass 6 in any desired position in its travel. 'A -driving chain 18 passes over the upper sprocket 15 and a lower sprocket 19 and is caused to' travel by turning the handle 16. The chain 18 carries a laterally projecting stud- 20` which engages a slot 21 in a depending plate 22. The plate 22 is detachably secured to the anglepiece 12 by means of screws 23. By rotating the handle 16 the A chain 18 travels and in its movement it raisesor lowers the glass 6v according to the direction of rotation by means of the pin iii? ' 20 working in the slot 21 of the :plate 22,

the plate 22 being normally secured to the glass 6 by means ofthe screws 23. y

The inner surface of the door is finished oil and the operating means concealed by applying the padding 24 and cloth 25'in a well-knownlmanner. r1`he fastening lugs 9 of the guides 7" are concealed by molding stripsy 26 or upholstery secured to the pillar 5. f 1

The operation of substituting 'a new glass asfollows:-Should the glass 6 become broken, the moldings 26 are removed to expose the fastening lugs 9. The upholstery 25 is laid back from above the casing 17 and the padding 24remnved as indicated in Fi 4. Normally the stud 20 stands in about ge for mechaniv forpatent filed Dec. 19, 1911, Se,

position shown in lig. 2 when the window is closed and if desired to substitute a new glass, the handle 16 is turned slightly to lower the glass 6 a trifle and cause the pin 20 to travel toward the left of the slot and beyond the center of the plate 22. The fastening screws 23 are then removed and the plate 22 and the operating means are free of the glass 6, the plate 22 falling lengthwise of the chain 1S and to, get it out of. the way the handle 16 is' turned to drop the plate 22 down to about the posi- `tion shown in Fig. 6. The object in first causing the stud 2O t0 travel toward the left of the slot 21 before detaching the plate is as follows z-It will be noted that in the righthand end of the slot 21 is an enlarged opening 30. AThis is for easer in assemblingthe operating mechanism, the stud 20 beingprovided with an enlarged head 31 to engage the back surface of the plate 22 and nor mally prevent it coming out',of the slot. 'lhe enlarged head 31 passes, when assembling fthe construction, through the enlarged opening 30 and to prevent the plate i removed and the glass and the guiding channels 7 are free to' drop down until the upper cess 10 in the head rail 4. -The glass with its carrier 11 and its channels 7 can then be swung `outwardly or transverse to the plane of the glass as indicated in Fig. 4, the posi tion of the operating mechanism remaining undisturbed.

After the glass has been replaced, the reverse operation takes place; to wit, the channels 7" and glass 6 are swung back into place and the lugs 9 fastened to the pillars. The plate 22 is brought up by rotating the handle 16 and again fastened to the carrier 11 by the fastening screws 23 after which the moldings and upholstery. are replaced.

In some cases, articularly in automobile doors the head rail 4 instead of being closed as herein shown is provided with an open slot through which the glass can be inserted. In this case it isnot necessary to swing` the channels in the manner shown in lfig. 4- after detaching the plate 22 from the glass. However, when a sealing device such as inends of the channels are free of the redicated at 35' (Figs. 1, 4 and 5) is employed,

it is necessary to swing the lower end of the glass slightly to allow; the sealing flange to clear the weather rail 1 in withdrawing and described except as may be set forth in the appended claims.
