Application led August 23, 1922. Serial No. 583,750.

To all whom t may concern.'

Be it known that l, LoUis LANE, a citi- Zen of the United States, and a resident of Habana, Cuba, have invented a new and 1mproved vWindow, of which the following is a description.

My invention relates to windows employingv sliding sashes and the present invention is intended more particularly asi an improvement on the invention forming the subject matter of United States Letters Patent No. 1,392,183, granted to me September 27, 1921.

The general object of the present invention is to improve the window frame jamb elements and the sash jainb elements or vertical side rails to effect line contact with each other as referred to in my patent above mentioned as well as to provide a form of frame jamb elements well adapted to coact with a novel weight box forming part of the present invention in association with a novel mode of hanging and arranging counterweights of the two sashes, the said sash weight box and the mode and means for 'hanging the weights being hereinafter fully referred to. 4 4

The nature of the invention and itsdistinguishing features and advantages will more clearly appear as the description proceeds. f

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 3 is adetail in side elevation with parts broken away and others in section showing the window structure adjacent the juncture of the sash weight box with the sill;

Figure 4 is a horizontal section on the line 4 4, Figure 3; I

Figure 5 is a trz-uisverse vertical section on the line 5--5,Figure 3;

Figure 6 is a horizontal section of a modilie'd form of sash weight boX and the adjacent window frame jamb element. 4 p

In the illustrated example the window -frame includes a top bar or frame head 10, l 'a sill 11 andwindow frame jamb elements 12. The window frame jamb yelements 12 are of channel form with transverse flanges 13 as in' my patented construction above referred to but in the present construction the members-13 are in the form of intermediate members, there being formed on the jamb elements l2 terminal portions or flanges 14 directed outwardly in the general plane of the window, that is to say, toward the'sash weight boxes `hereinafter referred to.

Guter stops 15 as in my patented construction referred to are Z-sha-ped in cross section 'and secured by screws 16 or their equivalent. Similarly, inner stops 17 Z- shaped in cross section are employed and one. fla-nge thereof secured by screws 18 or the like to the member 13 of frame jamb element 12. from the sides or main flanges of the jamb elements 12 to form with said sides channels 19 to receive the longer flanges 2O of sash jamb elements or vertical side rails 21 of the sashes A as fully described in my mentioned patent.

In the present construction, however, the flanges of the sash j amb `elements 12 instead o-f extending in a direct line into the channels 19 are formed with oblique intermediate portions 2()a the arrangement serving to effect proper contact of the flanges 20 of thesash frame j amb elements with the frame jambs 12 and'stops-15', 17." To vincrease the weather tight character of the structure vertical strips 22 may be applied to the members 13 of the frame jamb elements 12 between the same and the stops 15, 17 said strips 22 extending into the `channels 19 and being returned for effective contact with the edges of the flanges 2O .of the sash j amb elements 2.1.

both weight' pulleys near the top of the window frame so that the` weights by this arrangement travel up and' down' in their respective portions of the4 weight-box Apassing each other as the'sashes move up and The stops 15, 17 are spaced down, with each weight using onlya part of thel vertical height of its compartment of theweiglit-box and with the result that a largeV part of the total weight space provided in the box always vremaining unused,

Such liollbwy portions affilier weightF box have many objectionable features and While in wooden frames there is very little objection to such form of con'structiony as to cost, owin to the nat-ure of the material employed 1n the construction of the boxes, in metal windows suolrboxes so made with dongle weight space area in cross section, qnite` .expeni'vejand-f it is .one prpOse off' my. invention' toasecre al substantial savinig" 'I'nthis respect by' using'. only a `single coni' Ltment weight-box having anl interlriji'ediatiefcross sectional` area that theweights arfefdispolseih ini said"y boxi ini tandemL or one abovefthe. other in` the same axial line and soi that in which single box each weight travels only: .itspredetermilned portion ,of 'the vertical height of! the weight box which is preferably [extended downbelow the sill level olitle window aj short distancein order to ai suiei'ent-- weight travel distance and' permit. that` the lower sash'. may be raised the heightvv required. to aiford the greatest pr'acticafl, utility in ventilationx in the Window.

Y i

Thesasli weightl b'o-x shown is threesided' and at the openi side, thereofl presents terminal portions overlapping the terfianges 114 of the frame: jomb elements 12 t* which they are suitably fastened. Eajcl. weight 23' at' that side dist'owaid'tlre interior of the room or f inner side of the windowhas doors or removable panels 261i fianged to fit ini channels 25 formed on the said box 23. Said doors are detachably secured as by screws 27. The box 23 isI continued below the sill 11 as indicated at 123. To coordinate said box 23 and sill 11 the web or top of the sill (which lsill is chan-nel form in cross section) is cut'.

near the ends to conform to the cross section of the frame jamb element-412, the latter being continued as indicated at 112 throu h and belowsaid sill. That portion of `te web ofv the sill 11 lying `outward of the frame jamb ele-ment 12 is out as indicated by dotted lines, Figure 4, and turned downwardly against the sides or flanges of the sill as at 284 and secured by bolts or rivets 29, thereby leaving a clear opening through. the sill 11 to the box extension 123 for the movement ofthe lower sash weight below the' sill as will appear. Angle pieces 30 are laidv against the weight oi the sill 11 at the under side as clearly seen in Figure 4 and riveted or otherwise fastened thereto. Said angle pieces have ribs 31 overlapping the sides oi the frame jfamb 12 and secured by bolts 32 or the like thereto.` Similarly, other ribs 33 are formed on angle pieces 30 and overlap the terminal flanges 14 of the frame jamb elements 12 and are secured to said terminal portions 14 and to the terminal portions 24 of the box 23 by bolts 34 or the like.

'Phe provision of the angle pieces 3() fastened as described, strengthen the window frame at the juncture of the sill and ja1nbs.-

The sash pulleys 35 as will. be clear from Figure 2 are disposed in planes oblique to the medial plane of the window and converge toward a point approximately central of the box 232 so that the sash chains 36 will hang pendent on a line nearly central of the sash weight boxes. The weights 37 of the respective sashes are disposed one above au other in vertical aliuement or tandem, the al-ining weights having movement in one box 23 which therefore has an area only slightly larger than that of a. single weight. Each of the two aliniug sash weights in a bor` 23 has movement at a point from a horizontal line adjacent the sash to a point below the sash. v

It is to be understood that in connecting the head 10 with the weight boxes 23 substantially the same construction is provided as' with respect to the sill` 11, the downturned portion 28y being formed from the web of the head similarly to the formation of these members from the web of the sill and the described angle pieces 30 being employed at the head as well as at the sill.

The pulley pins 38 are passedthrou h brackets 39, 39 secured respectively to t intermediate members 13 of the frame jamb elements 12 and to the central web of said Y claim l.
