T all wil/)m it may concern: p

Be it known that I, JOHN B. CLERMONT, a 'citizen of the United States, and resident of Vthe borough and county of the Bronx, city and State of New York, have `invented certain new and useful Improvements 1n @perating Means for Sashes Having VSliding and Pivotal `Move1nents, of whichfthe following is a specification.

lvy invention relatesto windows andhas for its object 'to provide a means for readily operating windows which reasonof their position ,are not easily accessible or conveniently operated or which, owing `to their "surroundings, are purposely protected or made inaccessible. 'i i KA further object of my improvement fis t0 includea moans whereby rwindows located asabove set forth and which in addition to their vertical sliding movements have the sashes arranged so as tobe .capable ofpiv- (it-al movements relatively tothe window casing for Ventilating and vother purposes, may be readily manipulated `in the desired manner Without necessitating the removal o'l" lthe obstructing or protecting means or theu'se of ladders and .the like to bringjthe operator within reach of said sashes.

i Astill further Yobject of my invention is tov construct my improved mechanisms yin such a manner that the same are proof against intentional lor unintentional disarrangement through an unintended actuation thereof.

` @ther objects of Vmy invention will appear from the description hereinafter and theV features of novelty will be kpointed out in the appended claims.

Reference is to be had to the accompany-` ing drawings which illustrate an example of my improvement and Vin which- Figure 1 is a front elevation of awindow made inaccessible or protected by a'screen; Fig; 2 isa longitudinal section thereofV on the line 2-2 of Fig. `l; rFigB-is a horizfontal-section on the ',line33i of Fig. lgiFig. L

is a vertical section'on the line of Fig. 3; Fig. 5 is a 'detail-view partly in section of a `sash 'operating means; Figf'isfasectiona'lview on the line 6-6 of Fig. "5.; and Figs. 7,18 and 9 are "detail views of various parts of my improved construction. y

For the sakeof simplicityand ldescription I have illustrated and'will hereinatterdescribe my improvements in connection with Specificatcncf Letters Patent. Patented Aug, 1,7, 1915, Application filed December 4, 1314. Seria1 No. $75,426. i

aiwindow, the lower sash of which at F,least `is capable of a `pivotal movement relativelyfto the ywindow casing in. addition to its VertrV cal vsliding movements it being understood that this is only` an example and that said improvements, either entirely .or in'part, are capable of use in connection with windows of ordinary and other types.

Inthe drawings l0 represents the `Wall of a building having an opening in which ,a window casingjll islocated, said casing `accommodating the upper sash f12 and lower sash 13 in .the usual manner soV that said sashes are capable of a vertical sliding movement therein. ln the illustrated arrangement sash cords,` chains or thc like 14e .are connected at .one end with Seach sash 12 and 13 yand pil-.SSn pairsto opposite sides ofthe casing and haie Atheir opposite ends each connected with a single weight oi-with twin :weights 15 whereby each sash is counterbaflanced respectively by one or .more sash weights located at one side of the casing `and movable in suitable chambers Vtherein and .an arrangement commonly `fknown as -a double hung windowis secured.

4.lnthe villustrration vthe `window is protected onfth'e outside by-means ofrguards ,or hars 1G andV .on the inside by imeans of a grating or screen 17 lthe latter being located at a distance from said window and extending from the ceiling to the floor of ,the room or `terminating at .the level of the Window sill, the space .between .the lower end of .the screen 17 (and vthe window sill in the'latter case being closed in fany suitable .manner as by means of a horizontal screen L8.

The vertical screen 17 may lextend between vertical portionsl) .olf the building wall located adjacent to opposite vertical edges .of the window iiC the constructionpermits Vthis or the spaces between ,the vertical edges o'tsaid screen' and said window may be closed by additional vertical transverse screens or lthe-like Similarly, ,if the .screen 1.7 does not extendtofthe ceiling .the space between Ithe top `thereof and Vthe .window7V may be covered in any ldesined -manner .as .by means lof another 'horizontal ,screen or zthe like. .Hi the'screen 17 terminatesatthe level ofthe window sillV the space below the same maybe utilized to accommodatea radiator or other `heating device .which `may .either rest onthe Alicor or `"be seculiedto .theavall lip as shown. With this arrangement the window .is completely protected and ordinarily is inaccessible, it being understood that the vlower portion 17a or any other part of the screen 17 may be hinged or otherwise supported so as to be movable when access to lthe` window by authorized persons isv de'- slides 23 and 23a being arrangedV to travell along the faces of the members 17", and being preferably provided with operatingV f handles 24 and 24a respectively.

A`chain, wire cable or cord 25 has its one end securedl to the lower portion of the weight or weights 15 which counterbalance the lower sash 12 and passes over suitable pulleys' 26 suitably vlocated below the window, a similar cable 27 having its one end attached to the upper portion of the weight or weights 15 passing over suitable pulleys 28 suitably located above the said window. The opposite ends of the chains, wire cables orcords 25 and 27 are suitably secured to the web 22 of the slide 23 for instance by means of a clamping plate 29 so that an endless connection is formed in which the weight or weights 15 and the slide 23 is located. Similar chains, wire .cables or cords 25 and 27 pass over similar pulleys26 and 28 and have their opposite ends similarly connected respectively with the weight or weights 15 of the upper sash 13 and the A web 22 of the slide 23a.

When the window is fully closed, it will be seen that the slide 232L is located at the upperV end of the slot 21a while the slide 23 is positioned at the lower end of the slot 21. If it is now desired to lower the upper sash 12 a downward pull is exerted on the handle24a to cause said slide 23a to descend in the slot 21a and thus exert a pull on the cable or cord 27 which pull will be communicated to the weight or weights 15 and thus lift .the same. Owing to the fact that the upper sash 12 is in this manner relieved of the restraining influence of said weight or weights v15 the said sash 12 will descend bv gravity until the actuation of the slide 23 is discontinued or the lower end of `the slot 21 is reached. The chain, cord orwire cable 25 during this movement simply follows or is drawn along and in no way interferes with this operation as will be readily apparent. To again raise the upper sash 12 the slide 23 is lifted in the slot 21 throughV the medium of the handle 24 thus causing wire cable 25 which is transmitted to the weight or weights 15 and lowers the same and in consequence again'raises the sash 12, the chain, wire cable or -cord 25 meanwhile being simply drawn over its pulleys to permit this.4 If it is desired to raise the lower sash 13`the handle 24 is lifted to raise the y slide 23 in the slot 21 and cause the` chain,

wire cable or cord,25' to draw the weightV cord 0r wire cable 27 to return or raise'the said weight or weights 15'and permit the sash 13 to descend. It will be seen that in none of the operations ldescribed a-boveis it necessary to touch either sash, the manipulation of which as described is accomplished entirely by means ofthe hand-les'24 and 24a;` It will further be seen that with my imi proved arrangement the movement of the respective handles is at alltimes coincidentally in the same direction in which it is intended to move the particular sash thus doing away. with the necessity Vfor any specialthought being given to the operationof the mechanism when any particular actuation of a given sash is desired; Vln other K words the operation is the saine Aas it each sash were itself takenhold of .in the Vusual way and operated, the raising and lowering of the lower sash 13 being accomplished by corresponding movements of tliehandle 24 Y while the lowering andraising of the upper sash 12 is eiiective by similar movements of the handle 24a. Furthermore the location of tance away from the window and necessitates noA removal of said protecting screen or any part thereoi when an actuation of either or both sashes is desired, thus' doing away with the possibility of leaving the winl-V dow unintentionally unprotected. p

'i VInstead of utilizing my iinprovedarrangement as described above the same may be used for actuating bulky windowsor windows which are located beyond ordinary reach, and which are protected' as described or unprotected, theslots, slides and handles being in this case located, for instance, at:

opposite sides of the window-casing or the adjacent wall as the case may be and the cooperating chains, wire cables or cords being correspondingly located.

Y It will be obvious that myimprovements as so far described may be used in connection rae atively to the c'asingparticularly for ventilating purposes.; In the illustrations VI have shown such a V'window in which the` sash cords or chains v14, counterbalanced as de-` scribed, have ltheir one end pivotally' lconnected preferably with the lower portions of the sashes 12 and 13 respectively. Vith thisv arrangement as carriedout by way of eX- ample in the ldrawings the. upper sash 12 is pivotally movable and reversible inthe casing under certain conditions mainly for the purpose of cleaning 'and as this specific idea forms no part ofthe present Vinvention `itis not believed necessary to describe the same morefully herein. `The lower sash 13 is,I

however, provided with'anysuitable type' of automatic Ventilating device for instance of thekind forming the 'subject matter of' my co-pendirug.4 .application Serial "Nd 864,230 for limiting its swinging movement under' normal conditions sothat vsaid sash 13 may be adjusted for instance forventilating purposes when desired. With windows protected or made inaccessible as described it would ordinarilybe im-4 possible to swing the sash'asdescribed with# out first disturbing the protecting means or first otherwise rendering the window 'accessible and thus liable to unauthorized iiuterference. To avoid `these contingencies and to provide for the ready manipulation of said sash 13, I have provided the means shown best by way of example, in Figs.` 7-8f9 it being understood that, in protected windows of. the swinging type as herein shown, .the usual movable stop beads or lock` ing strips for normally locking the lower sash against a pivotal swinging movement Y supported in suitable journals between they Aso are omitted As illustrated my improved operating means comprises a rock shaft l30 window and the `screen 17 and 'carrying de` pending arms orlevers`31 one of which may be continued to form an operating handle 32 projecting in any desired manner eXteriorly of the screen 17 withinreach of a per-V son in the room of which the Window forms a part, it being understood that vboth arms or that the handle maybe otherwise operae tively connected .with the shaft V30, if desired.

In the example illustrated the said arms 31 at'their lower ends are' provided with upwardly open recesses 33 adapted to receive and accommodate pins 341:` which'are preferably removably secured as by screw-threading Vin brackets 35 secured to the lower sash 13 at intermediate points of its vertical side members and extending forwardly there-` from, said pins being preferably vformed in the nature of thumb-screws with operating heads 36 to facilitate their attachment with and removal from said brackets. Instead of detachably connecting the pins 31with the brackets 35 `by screwfthreads, other means such as for instance a bayonet fastening may be employed for this purpose. f

In the normalpposition of the parts the recesses 33 are located in the vertical path traversed by the pins 34:V as the sash13 is raised and lowered and being upwardly with the coperating pins 34, the said braclc.

ets 35 may be formed with downwardly open recesses and the cooperating pins 34 located' on-the levers 31 if this. should be, desired. Inother words the arrangement of pins and slots asfshown may be reversed relativelylto the brackets and levers without in any way changing the operation of the parts. In this lowered position,.the sash 13 owing to the absence of the usual stop beads or locking strips is at all times capable of being swung inwardly on its pivots, thisinward movementbeing normally arrested by the automatic4 Ventilating device above men# tionedor by any othersuitable arrangement adapted to maintain said sash in an inwardly inclined position for Ventilating purf poses. To actuate or swing the said sash as mentioned above the handle 32 is moved upwardly thus bringing about a rocking movement of the shaft 30 and causing both arms or levers 31 to swing in a direction away from `said window. The actuation of the arms or levers 31 will exert a pressure in the same direction on the pins 34C and in consequence'will swing said sash 13 on its pivots so that the said sash will incline inwardly at the termination of the said operation and its upper'portion will be spaced from'the lower edge of the upper 'sash to form a space through which air may enter into the room.

vTo return the sash to its norma-l position the handle 32 is moved downwardly to bring about a reverse operation of the parts, it being'understood that the upper sash may be 4 freely movedin a Vertical path without interference during the above described swinging ofthe lower sash. Any suitable means may be provided for preventing the said lower sash from raccidentally or uninten-` tionally swinging on its pivots, a contingency which otherwise might be occasioned by wind pressure or otherA canses ,owing Vto the absence of the customary lockingstrips.

Inthe illustrati) n this means isshownin the nature of a segment 37 `rigidly secured in po-l sition adjacent to the handle 32 for instance on one of the angle irons 1 7 and provided along its freeV edge ,Wth'teeth adapted to coperaterwith a Vpawl 39 carried by -Sad f Y handleu32.. 'The pawlf39 is provided with an operatinglever and is maintained in operative position lby means of a svp-.ring '41 it being understoodthat the teeth 3S and pawl 39 ,cooperate to prevent an npward movement of saidhandlel 32, the teeth'33 and 'pawl 39 being shaped so 4as ,to permit thelatter to readily ride or slideA over'saidteeth is prevented becauseot the connection fbee .25

'Y gaging the sa'idpawl 39 with any one'of-'lthe during'a downward movement of said 'handlef 'VVhenthe sash 13vis in its normal Vpor-ii'- tionin the sash llthe pawl'g39 is inlock-ing engagement with a-lowerftooth38 so `that an`V actuation of the handle 32 in an upward di-t Y rection 'is impossible and ,an "unintentional inward swinging movementofthe said sash tween the pins 34 and recesses By ,en-V

other lteeth 38 Wthesaid ySash maybe loclgedin any intermediate inwardly inclinedv position Y against a similar unintentional movemenhit being apparent that this vconst ru ctionY in some cases may permit the omission of the automaticI Ventilating ldevice hereinbe'fore referred to. Vlhen itis desired Vto in tentiori-` ally swing the sash 13 onits pivots the pawl 39vis iirst disengaged from ,the particular tooth 3,8 by exerting a' pressure on the lever 40 against the tension ofthe spring 41 after which the handle 32 is free to be moved upward/ly as described above. vIn the absence of anyv provision against thesame it would be possible for aperson to'iirstiraisethe sash 13 in the casing 11 to removefthe pins34 from the recesses 33 and then swing the levers 31 away from ,the window throughvan actuation of 'the handle 32 thereby moving the recesses 33 out of the path of said pins 34 and thus completely disarrange v the mechanism. To ,guaid'againstsuch a contingency I have provided a 'dog 42 pivoted at 43 upon aV stationary element of the construction 'in close proximity 4to the lower end ofone of said levers or alims 3l and weighted at one end as indicated at 44, the end v of said being arrangedv to cooperate with a projection or pin '46 carried by a lever 371 'aswill hereinafter more fully apliiear.l The said dog 42 is provided at the end 45 with a member 47 extending below the lower edge 48 and terminating in a horizontal flange @arranged t0 ,project alongside olf .enefloi the recesses 33and 'into the Vpath'o'foneof the pins 34. The pivotal movement of said dog is preferably limited `by any suitable means as for instance through 'the medium of a stationary pinl'O extending into a sloty if 'With the partsfin proper :ce

My .improvements @alge particularly adapt-Y or'nse `1n conneetionwith windows,ofy

other institutions in which theinmates are intended to be confined and permits the use of any type of window, swinging or otherwise with perfect safety and without danger that the same willbe misused or the" operating mechanism disarranged or its `utility destroyed.' Access to the windows by authorized persons for cleaning or other purposes may be provided for in any desired way.

By connecting the weights 15l with the slides 23 and 23:L as described the latter with `their operating handles 24 and 24a ymay be located at any distance tromthe sashes and upwardlyV inthe casing in an even and level manner no matter at what point of the sash the force necessary tobringabout such aYY reversal is exerted. 'During' such reversing operation the handles 24 and l24a may further be .utilized to retard .the speed with which said lower edges travel upwardly in the casing thus making it absolutely certain that the reversing-operation may be accoms plished in safety and in a maximumly conf venient manner. It willfofcourse, be evident. that instead of providing the dog 42 with a weighted end 44, the same may be controlled in other ways as by means of a spring exerting a tension tending to move the end 45 at all times into the pathV of the projection or pin 46.

Various changes in the specific forms shown and described may be made within the scopeof'the claims without departing from the spirit of my invention.
