sAsH-FASTENER.

` Application led J' une 22, 1917. SeriaINo. 176,440.

To all whom t 'may concern.'

Be it known that I, ALBIN I-I. HUToriiNcs, a citizen of the United States, residing at Buffalo', in the county of Erie and State of New York, have invented new and use ful Improvements in Sash-Fasteners, of which the follo-wing is a specification.

This invention relates to a sash fastener,

and has for its object the production of a de-V vice of this character which is simple and inexpensive in construction, easily operable,

and also capable of being readily applied to practically all windows as now generally constructed.

In the accompanying drawings: Figure l is lfragmentary elevation of a window, showing my improved sash fastener applied to the opposingvparts of its upper and lower sashes. Fig. 2 is a fragmentary vertical section, on an enlarged scale, taken on line 2 2, Fig. l. Fig. 3 is a rear end elevation of the sash fastener applied to the lower sash. V Figyis a top plan view of the same. Figs. Sand 6 are detached perspective views of the slide and base of the sash fastener. Fig. 7 is a top plan view of the blank fromwhich thebase of the fas# tener is constructed.

Similar characters of reference indicate corresponding parts'throughout the'several views.y

Although this inventionis applicable to windows of various kinds and also other forms of .closures for openings, the same is shown in the drawings, for example, applied toa window having a frame 1, a lower inner sash 2 and an upper outer sash 3,-these sashes being guided at the corresponding1 vertical edges ont-he frame in the usual an well known manner.

In its general organization, my -improved sash fastener which is associated with these two sashes, comprises a base mounted on the lower sash, a slide or carriage mounted on the base so as to be capable of movement toward and from the inner face on the side of the uppersash, and a pair 0f llned grip ping members pivotally mounted on the slide and adapted' to engage'the inner side of the upper sash. The base may be variously constructed,

-- Y but in its preferred' form the same is conj Specification of Letters Patent.

byv bending the adjacent edge portions of the plate upwardly and inwardly, and an upright abutment lug 6 arranged at the front or inner'end `of the plate andv formed by doubling the respective part of this platel upwardlyand downwardly and outwardly upon itself, as best shown in Figs. 2, a and 6.v .i i

This base isl preferably secured to the upper side of the lower sash adjacent to the frame by means of screws 7, 8, passing through openings formed in the rear and front parts of the base,r as shown in Fig. 2, the front screw openingbeing formed partly in the body of the plate 4 and partly in the folded: portion which forms the lug 6, so that the front screw 8 not vonly. serves to hold the.

plate down upon the inner sash butalso holds the lower portion 6 in its proper rela#l tive position against displacement.

Sliding transversely on top ofthe base plate l is a carriage or slide 9' which is guided in its movements by means of longitudinal guide flanges 10 arranged adjacent to its lower side and engagingwith the guideways 5 ofthe base. This slide or carf riagel may bemoved transversely in a variety ofpways,the means for this purpose shown in the drawings beingsuitable and `comprising an adjusting shaft or spindle 1l ar' ranged horizontally and transversely with reference to Vthe/sashes and having its rear or outer rend provided with an external screw thread 12 which rengages .withk an in; ternal screw threaded opening 13 in the carriage while its outer end is provided with ahandle or thumb piece 14 for manipulating the same and its central partis mounted on the lug 6,.so as to be capable of .turning therein but held against lengthwiseA or axial movement thereon. `v i i The connection betweenllthis adjusting spindle and the lug 6 is.- preferably effected byproviding-the lug with any upwardly opening notch' 15 in its central .part into which the adjusting spindleV may be introduced from above, and providing thisspinv` dle with front and rear shoulders or collars 16, 17, which engage withthe front and rear sides of the lug 6 and thereby confine the spindle against axial .movementin Athis lug although permittingthe same to beturiied freely. It yfollows from this construction that' when thespindle 11 is turned-byineans of its handle orthumb piecel4, the carriage 9 and the parts `mounted thereo'nwillbe moved horizontally iand' transversely lorr'tlfie iio upper edge of the lower sash and toward and from the inner faces ofthe` upper Y On the carriage are mounted a pair of gripping members which, when in the117`0p'' so as to prevent either of these sashes from being moved vertically relatively vto eah-' other so long as the parts remain in their operative position. f In the preferred' form' ofz these gripping k members they are con`v structed in the forni ,of levers or toggles 18, 19, which' arev arranged one abo-ve the other and arepivotally connected at their front ends by means of a horizontal pivot 20 to theiupper part of lthe carriage. For receiv-Vv ing these levers, the carriage is provided with a longitudinal groove 21 in its upper and rear part, andy in order topermit of these levers being arranged one above thev other and still obtain a Auniform series, one of these levers, preferably the upper one n18, has its hub made single and arranged on the central partof the pivot pin y20, While they hub of the lower gripping lever 19 is bifurcatedor made doubleand arranged on the pivot pin 20 so as to sti'addle the hub of the upper leveigas best shown in Figs. 2, 3 and 4. Normally, the gripping levers` diverge rearwardly from the pivot pin 20, the lower lever being arranged below a horizontal line drawn through its pivot andthe upper lever labove this line. At their outer or rear ends lowerlgripping levers or toggles 18, 19, en- Y gage with the inner side orsurface of the upper sash at points above :and below a horizontal line drawn through thel pivot pin 20, it will be impossible to raise or lower x either one of the sashesrelative tothe other. This' will be apparent ffrom the fact that upon attempting a downward movement of the outerl sash relative to the lower sash, the upper toggle lever 18 will resist such movef f nient by reason of its inabilityto move from its upwardly inclined position OH hO' zontal position in line with itsl pivot and by reason of the fact that'the lsashefs are held v'a'gainstY "separation in Y a direction transy versely=,'fo'f the sashes'infzthe' guideways [of the Vwindow yframe. *Upon attempting to raise the 'upper "sashfthismovement 'will be resisted the loc/kingatiou y.of .the lower lever 19,k which tends* .t'ofs'wing from its y downwardlyinolined positionto a position libriz'ontally'fin"line with its pivot.` 'The #ses risalta@ 11.113911; were:

i u VVh'env it' is`des`ird to render the sash j 'fastener inoperative from the inside of the erative position, produce a grip upon the.. v upper `sash .with a camor toggle-like action, v

building so as to permit of freely opening yandclosingthe window sashes forcleaning,

so as to disengagethe'sellevers from the upper sash. The A'downward -movenient' of-ft'he lower gripping lever 1'9`1i's -fli'mited by en# gagein'ent of theupperjs'ide of the base platel f 4, so that thefsanieis-always.inpositionto?A properly rengage'tlieiniier side ofithef npi/ per sash whenthe carriage'is 'mo-ved outwardlyinto its operative position. v'InasmuchV however, as the lupper gripping lever f T 18 would, in v'the Vvabsence of any provision to vprevent it,"ldrop^froni its upwardly iii-1 clined position into a nearly 'horizontalpoi sition when free, means are providedfor" yieldingly holding the same 'in 'its' elevated inclined vposition while V4the carriage is nioved into its operativeposition." Forl this purpose the 'carriage provided inftheb'ot-i tom part of its notch with' av detentA spring 25 *n which hasan upwardly-curved salient portion adapted to rloe engaged 'by a ldetent'nose 26 on theV underside'lof 'the upper lever and the latter is'a'lso provided'v with a' shifting finger 27 projecting' vinwardly therefrom.

When therefore itis' desired to render the 'if sash fastener inoperative and leave thefsai'ne in suchI conditionfthatfit v"can be promptly rendered operative, the 'attendant' first 'de` presses the finger'piece 27 sothat the nose 26 of the upper'gripping lever 18 springs from the inner side of the salient part of the detent spring 25 to the outer side thereof,- wherebyfthis lever will be yieldingly held in this position by this spring while per,v sash lintoV itslinop'erative' position.v When returning'.` the. sash -fasten'er to its operative position, the oarriageQ is ,first moved outwardly 'by means ofl 'its adjusting the carriage-9 is withdrawn from" the upi screw yuntil the jaw of thef'lower' lever'19 is in proper y'enga'gement with the" upper sash and then the shifting "ng'e'r 2'7i`s' raised for 'turning the'upp'erlever f18 downwardly un til its "jaw" alsofengfages' with the 'inner-*side 0f the Pref Sash; during which movement off this lever its nose ,2671 rides .over the salient` partA offtlie'detent springA 25 lfrein the front' toth'ef rearl Iside" thereoTf-,ilint'othe y 'po'siionshwnrnrFigi 2'; thereby returning the parts to their normal operative'positioii `f Takamine Qwhle, the 'sash *fastener-fis comparativelysimpleinfeonstructipnllcengid'eringth-yargas functionswhich-ieper; farms g a iicjan te app-nea to ma wisdom "VWitltioiit any iittin'g' i alte tion of arts, "'-fl and it can be very easily and conveniently operatedffor either lowering or releasing the windowsfand owing to its compactness, the same does not detract from the Vappearance of the window.
