T 0 all whom t may concern.'

Be it known that I, LoUIs S. GRUnn, a citizen of the United States, and a resident of Arnold, in the county of lVest-moreland and State of Pennsylvania, have invented a new and useful Improvement in W'indows, of which the following is a specification.

The objects of the invent-ion are to provide a window construction which will be durable, compact, convenient to clean and easy to operate; which can be easily repaired whenever necessary; and which can be swung to a position to permit thefull space occupied by the window to be utilized.

. Further objects are to provide convenient means for balancing the sashes and for locking themv into any desired position; to provide screens forming a part of the window construction proper which can be easily attached to or released from the Sashes and which will be completely hidden when not in use; to prevent the leakage of rain or melted snow, which trickles down the exterior of the window, into the interior of the lower sill; and to produce a window in which .all of the operating mechanism therefor is protected and is out of sight so as to present a pleasing appearance.

The window illustrated as the preferred embodiment of the invention is constructed entirely of metal, the outer casing, the main frame and sash frames being formed of suitably shaped pieces of sheet metal attached together by any well known means. These parts which are' exposed are preferably made of some lmetal which is capable of resisting the elements as for example, sheet copper. The particular material used, however, forms no part of the invention as any suitable material may be used and it is not intended to limit the invention beyond that particularly pointed out in subsequent claims. l

In the accompanying drawings forming a part of this specification, 'the same reference characters denote corresponding elements through the several views in which Fig. 1 is an elevation showing the window completely assembled, lthe screens and operating mechanism being indicated in dotted lines; Fig. 2 a vertical sectional view on line I'L-II, Fig. 1; Fig. 3 a transverse vertical "sectional view with parts shown in elevation on linel III-III of Fig. 1; Figs.

4 and 'fragnientary sectional views with partsy in elevation showing` details, Fig. 6 a ltransverse horizontal sectional view on line Vl-Vl of Fig. 1; Fig. 7 an enlargedy f to Fig. 7 showing a modified-form of 'the actuating mechanism; Fig. 9 a section" also showing theoperating mechanism taken on line I'x-JX'of'Fig. 7; and Fig. 10 is a fragmentarydetail view showing therelative positioning of the partsof the locking device illustrated inv Fig. 4 when operatively engaged. l

The window comprises the'ou'ter casing 1 so shaped as toprovide a recess 2 in which is hingedly supported at 3 and 8 the. main frame 4, in which the vertically slidable sashesV and 6 vof a well .knowntype are mounted.l The outer casing 1 is formed at its top with a depending portion7 and' atl its sides with inwardly projecting portions 8 ywhich act to form a limiting abutment or stop for the frame 4 when said frame ,occuf pies its normal position as illustrated lin Fig. 1, and `in full lines` in Fig. 6. The

frame 4, however, may be 'swung outwardly to the position indicated by 'thev dotted lines in Fig. 6 so as to render it possible yto utilize the entire opening through the casing 1. rl`his is found to be of particular importance in oiiice buildings and similar structures fory the admission of large safes or pieces of furniture. The window is also swung to its.

dotted line position for the purpose of cleaning the exterior thereof.

At one side of frame 4 are mounted the spirally grooved shafts 9 -and 10 journalled at their upper ends in a bearing Vbracket 11 and at their lower ends in a pair of spaced bearing blocks 12 and 13, respectively. l The shafts have'attached n ear their lower ends y pinions 14, 14 meshing with the respective pinions 15, 15', both of the latter encircling a rod 16 slidable in an aperture 17 in block 12 and a recess 18 in block 13. intermediate Y its ends, the rod 16 carries a pin 19 which is adapted to lit into the grooves 20, 21y in the adjacent faces of the respective pinions 15, 15 for a purpose to be presently explained. l In Fig. 7, the pinions lyand l5 are shown as positioned adjacent each other leaving but a small space between their abutting faces, while in Fig. 8 is illustrated a modified form in which the pinions are spaced apart by the abutting arcuate bosses the Width ot the open space indicated at 19 being slightly greater than the Width ot the pin 19. The length of the pin 19 in this form is less than the distance betvveen diametrica-lly opposed portions of the bosses so as to freely rotate Within the space 19 Without touching the same. rEhe construction in Fig. 8 permits the shitting of the rod and pin 19 to engage either pinion without first bringing the grooves in the faces of the same into aligninenhthe pin 19 being simply projected into the space 19 and turned therein until it comes into a position to align with the groove into which it is to be itorced.

The bearing block 12 is equipped with a pin 22 provided with a round-ed end springpressed into either of tivo series ot shallow impressi-ons 23 formed on the rod 16 and a similar pin 24 fits into the depressions 25 in the tace of pinion 15, the bloclr 13 also being similarly equipped as shovvnat 25 tor the purpose of slightly retarding free rotation of the pinions. The end oi" rod 16 has a handle 2T attached thereto to which access inay be had through lthe closure Q8 in the trame rlhe open position ot closure 28 is indicated by dotted lines in Figs. T3y and 7.

Sliding upon the shafts 9 and 19 are the respective nuts Q9, BO, each nut being provided with an internal tongue or similar device 'for engaging the spiral groove-ot the shaft. The nut 29 is connected to the loiver sash and the nut 30 to the upper sh by an extension 30 or 31 which is pre ably tached adjacent the upper end oi the sash. These extensions project through slots provided in the sash guiding grooves.

Rotatably mounted in the upper and loiver ends oi the trame 4 spring rollers 83 and 34. Upon each roller is -Wound a flexible screen 55 such as is comin-only used for excluding insects from doors and ivindoivs, Whose width is slightly greater than the Width oi the Window sash so that the edges thereof project Within slots provided in the sash grooves, the right hand edge viewed in Fig. 1 riding in the same slot through which the extension attached to nut 30 or 31 projects as previously discribe'd. The rollers normally Wind and retract the screens into the position illustrated in Fig. 1, the roller 33 cooperating yvvith the upper sash and the roller 34 with the lower sash in a manner to be presently described.

Each ot the rollers is removably mounted and since the construction used for this purpose is substantially the saine Jrior both rollers only that used in connection 'vvitn one need be described in detail. Si pintle on one end of the roller rides in an aperture in the bracket 37 rvhilethe squared exten sion 88 at its other end is retained in the slot 39 in bracket 11 by a latch 40 pivoted at 41 and locked as shown at 42. he means for retaining the squared extension on the lower roller differs from that of the upper one merely in extending the slot or recess in the bracket upwardly and providing an angular offset adjacent its upper extremity, and in pivoting the latch so that the normal position of its axis is vertical instead ot horizontal, as clearly shown in Fig. 3.

The screens are prevented from being completely Wound upon the spring rollers by catches 43 fastened to the tree end of each screen which projects through a slot in the sill or lintel for that purpose, the catches being of such dimensions as to prevent their passing through the said slot. The catch acts as a limiting means for the screen and is held iirmly in position by the tension of the roller for engagement with the of the spring-pressed sliding bolt 44 located in the sash of the Window.

For the purpose of locking the sashes in various positions as may bedesired, several means are employed. n the form illustrated in Fig. 3, shafts 9 and 10 `are provided with a series of recesses 45 With which the catches 46 carried by the nuts 29 and 30 co act. The main body ot the catch 46 is Jfornied of spring metal and its bent end eX- tends through an opening in the sliding nut so as to enter one of the several recesses 45 to lock the saine at any desired height. ln the normal operation of the device, the end of the catch is Withdrawn and the catch moved about its point of attachment k47 as a pivot out ot register with the opening through the nut.

in Fig. 4, the nut 29 is held at any desired position by the sliding lock 48, the` lock being pivotally and .slidably mounted upon a rod 49 located at the side of the shaft 9. rlihe main body of the lock 48 is provided with a pair of spaced fingers 50 Iadapted to straddle the nut Q9 and to be swung into the position indicated in Fig. 4, the lock being pivotally swung disengaging the `nut when not desired. By sliding the lock up or down upon the rod 49, the saine may be positioned to lock the nut and attached sash :in any desired position. Due to the loose #lit of the lock upon the rod any pressure upon either linger 5() tends to torce the lock askeiv resulting in a binding action eiectively holding the saine againstvertical movement.

In some instances, it has been found highly desirable to equip the Window rwith means for preventing the entrance of unauthorized persons such as burglars. Such means as shown in Fig. 5, 51 being a series oi spaced metal rods or bars projectingupivardly -through the lower sill which are attached to the lower end of the sash 6 thus forming a barrier when the sash-is raised.

In order to prevent therain-or melted snow which trickles down the exterior of the panes from entering the hollow sill construction and causing damage, and also to prevent the same collecting upon the sill, the sill 52 is inclined as clearly shown in Fig. 2 so t-hat any liquid co-llecting thereon will be readily discharged, the grooves 53 being provided to facilitate such action.

For holding the window frame 4 in its operative position in the outer casing a combination latch and lock 54 is provided as shown in Fig. 1, the portion 55 coacting with the portion 56 mounted upon the casing 1 in the usual manner. If it is desired to prevent opening of the frame 4, the catch 54 may be locked by inserting a key through the key slot 57.

The operation of the device is -as follows: Vith the form of actuating mechanism shown in Fig. 7, in order to shift the pin 19 from the grooves in either pinion 15, 15, it is first necessary to bring the oppositely facing grooves 20 and 21 into alignment, in which position of the parts, the pin 19 may be selectively engaged with either pinion by longitudinally. moving the rod 16. Subsequent rotation of the rod will rotate the pinion. The turning of pinion 15 or 15 results in the rotation of the corresponding shaft 9 or 10 and the sliding nut and its sash will be moved due to the cooperation between the nut and spiral groove in the shaft. Turning in one direction will cause the sash to ascend while turning in the opposite direction will obviously cause it to descend. By positioning the pin 19 so as to partially project into both grooves 20 and 21 both sashes may be moved simultaneously if desired, or a single'v sash may be moved at a time by projecting the pin 19 entirely within the groove of a single pinion, the disengaged pinion being prevented from turning, and allowing the sash to lower under the iniiuence of gravity, by the spring pressed pins 24 or 26 as the case may be, the tension of the latter means not being sufficient, however, to prevent the sash being moved by force, if desired.

1With the form shown in Fig. 8, the pin 19 may be projected into the grooves in either pinion, as desired, as previously described, and although this form is not capable of causing simultaneous actuation of the sashes, it makes possible the shifting of said pin from engagement with one pinion into engagement with the other regardless of the relative position of the other and without first bringing the opposite grooves of the two pinions 15 and 15 into alignment.

When the sashes have been moved to the positions desired, they may be securely locked at such points by releasing the catch 54, swinging the frame 4 inwardly on its hinges to the dotted line position in Fig. 6 and setting the locking means 46-47 Fig. 3,

or 48-50 Fig. 4, as previously explained,

when the frame is again swung into and locked in the position shown in full lines in Fig. 6 or in Fig. 1.

At night, it is intended to position and ing the bolt 44 from the catch 43. When the sash is moved to its full closed position, and the bolt 44 is spring-pressed to the left, Fig. 1, so as to bring its end into position to be contacted by the curved portion 43 of the catch, the bolt will engage the slot of the catch thus locking the screen to the window sash. Either a raising or lowering'of the sash when the screen i-s thus attached will cause the screen to be moved therewith thus closing the space between the sash and frame. The screen may be released regardless of the position of the sa-sh by simply drawing the bolt 44 to the right so as to disengage the catch 43 when the tension of the spring roller will retract the screen to the position indicated in Fig. 1.
