THOMAS. HANLEY; OF CHICAGO, ILLINOIS cAsEimEN'r WINDOW AND HINGE 'rrrnnnron Application filed December 10, 1930. Serial lNo. 501,206. l

The invention has reference. to casement ."windows or like constructions embodying hinges adapted to permit of a dual movement of one constructional part relative to another. 1 w

An object of the invention is to provide a novel construction of this character in which a hinge of improved character guides the movement' of one part relative to the other in one directionandsubsequently supports said partduring further relative movement iii-another direction; 7 v I More specifically stated, an object of the invention resides in the provision of a casemer t window or similar construction in which what may be termed the movable closure member has a sliding movement relative t'oa frame tofr'ee the parts from an interengaging relationship'before a pivotal movement of the parts is-pos'si'ble said closure member beingsupported by hinges fashioned to permit 'ofsuch sliding movement only when the'parts are in their closed relationship,"and to guide andsupport the movable closure in all movements thereof relative to said frame. J I I A further object of the invention is to pro- 'vide a hingeimember of new and improved construction for use in connection with casemer t Windows or like structures. v

More particularly, another object is to -provide a novel hing-e construction embody ing two hinge memberslconnected by a pintle and curl arrangement including a projecting part on the pintle-carrying member adapted to engage :said curl to support the members in more, than'one position of relativepivotal movement, said members having one position in which said curl andsaid part'are not en- ;gaged to permit of a relative movement of said members ina direction paralleling the axis of said pintle. J 7

Other objects and advantageswill' become apparent in the following description and from the accompanying drawing, in which: Figure l is a front elevation of a casement window construction embodying thefeatures of the present invention.

Fig. 2 is a fragmentary front elevation, on an enlarged scale, showing a hinge-member.

Fig. 3 isa transverse section. of a hinge member showingthe parts in the position assumed-when the window is closed.

Fig. 4 is a front elevation of 'amodifiedform of hinge.

While the invention is susceptible of various modifications and alternative construc tions, I have shown in the. drawing and will herein describe in detail the preferred e1n-'1" bodiment, but it is to be understood that Ido not thereby intend to limit the invention to the specificform disclosed,, but intend to cover all modifications and alternative constructions falling within the spirit and scope', of"

the invention as expressed in the appended claims;

Referring more particularly to the drawring, a casement window is shown,ffor the purposes of illustration, which. comprises ail frame memberlO and. a closure or .window member 11 arranged to fit relatively snugly therein. In such constructions,the window llis' mounted-for swinging or pivotal movement relative to the frame and a common dis-,1-

advantage inherentthereto is due to thedifthe lower portion of: the window and the bottom portion of the frame to preventthe en'- trance of airand moisture. In the present;v-

tionof the window and on the side thereof toward which thewindowswings. The win- .dow-receiving recess in'the frame 10 is somewhat longer than the window to allow the windowftoslide with respect to the frame to carry the window free or clear, of the up- 0 per edge ofvthe stool. v This sliding movement precedes the. pivotal movement of the window in opening it and follows such movement in closing the window.

'Means is provided in the form of binge membersfor supporting said window in the a frame, which members arearranged to guide and support the window in its aforesald dual movement. With particularreference to Fig.

2, a preferred form of hinge is illustrated as Y comprising a pairof'hinge leaves orplates 13,

ficultyin adequatelysealing the gap between 14 apertured in the usual manner to permit of their being secured to the frame and window 11 respectively. One of the hinge plates, in this instance the plate 13, carries 5 laterally spaced, transversely extending bosses 15 between which a pintle 16 extends. The pintle preferably is. secured rigi'dly: to the bosses in any suitable manner as by upsetting the extending ends of the pintle; The

other hinge plate 141 carries. OHQDITIHOTG (in this instance two) transverselyextending,.

relatively narrow curls 17 which are located intermediate the ends-of the-iplateftowengage the pintle at spaced points between the 5 bosses 15.

The arrangement and disposition of. the

Parts .i 10. tha in... a di ion -to. relative pivotal move nentof'thehinge plates, a relative sliding movement thereof,,in;adirection paralleling the pintle axis is; permitted.

When such a hinge is usedin connection with casement window constructions of, 1the character described, the extent of such-{sliding movement is slightly greater than the length of movement necessary to cause the window to clear. the stool.

Means is provided; for positively, supporting the hinge plates for pivotal movement .in various of their relativeaxialpositions,

o which means is automatically engaged orfdisengaged as said plates move relatively out of or into ,one position. In this instanc e,.this means comprises .one or more lugs18'formed, integrally" with the pintle-carrying plate 13 J toextend toward the pintle'into a position wherethe curls'17 may be engaged thereby. Herein two such lugs'are shown as being located substantially centrally of one side .of the hinge plate 13 and spaced'from each other 1 a, distance slightly greater than the width of one of the curls. '-Moreover,1ithe' lugs are so proportioned that in. one position of the plates 18, '14 the lugs may enter the space betweenthe curls 17. The curls, as may be seen .1 in'Figs'Q and 3, are not completely closed,

thereby providing gaps or recesses 19. therein througlrwhi ch tlie'lugs '18 may slide when the faces ,of the hingejplates are abutting.

Inoperation, the hinge plates. are first J properly secured to thefra'ine and window 5 such movement, acting as guides.

(see Fig. 1) so..that the faces of theplates will be in[abutment when the window is closed. ,As a resu'lt, the window is "free to movevertically of the frame, the hinges, in As .the window approximates the top limit of its ve tica lm rem' n t cl ar the. tO lL Z, th relative axial movement of the hinge plates disposes one of the curls 1'7 opposite the space between the lugs 18. .Uponjsubsequentpiv- Otalmovement ofthe win dow', s aid opposed lug is turned to enter saidspaceand restupon the lower lug forsupportingthe window for swingingjin 'its elevated position. It will be iden that, in thi jposi on, relative axia movement of the hinge plates is positively prevented and the window is held out of contact with the stool to prevent injury thereto.

When the window is closed, the interengagement between the lugs and curl is maintained until the window is completely closed,

whereupon the recesses-19 allowthe curls to side of the window.v It is, of course, obvious .tha'toone or more than two lugs, or curls, or

both, .may be employed without materially altering the structure.

"Figure; 4 illustrates a. somewhat modified formof hinge structure. In thisi'form, the

general arrangement of. hinge plates 13,: 14, bosses 15, pintle 16, and curls 17isunchanged except that each curl. .has anxintermediate, .arcuately formed recess 20 therein extending from the. free endofthe curl. A single-centrally located lug21 is carried bytheihinge plate. 13and is shapedand. disposed to enter one. or the. other of, said recesses- 20ldepending upon the axial relation of. the hinge plates.

The operation of this. formis substantially 'similarpto that of. the hingeshown in Figs-2.

.From .theIforegoing, it will bezapparent that anovel. construction for a casement window or the like has been provided which embodies an' improved .form of :hinge device adapted to guide a movement of thehwindow in the plane thereofand.subsequently to sup- ;port the window forpivotal movement inone V ofits .varlous. positions. Furthermore, such operation of the device isent1relyautomat1c.

.The structure involved is exceedingly sim ple and the hinge parts maybe formed by a die-casting operation wherebythe hinge may be manufactured and sold at a low cost. I cla1m as myinventionz .1. A hlnge compr1s1ng,.in combination, a

-,pair of hingeplates, a pintle rigid with one of said plates, apair of spaced-curlsonthe other of said plates engaging said pintle intermediate the -ends thereof .to permit of .axial movement of said curls along said pintle, and a pair of lugs on said gpintlecarrying plate extending. therefrom intothe path of axial movement of said curls,-said curls having recessestherein arranged in one relative plvotal position of said .plates to permit sald curls topass said lugs, said lugs being spaced apart a distance greater than the width of one of said curls'to receive one of said curls .therebetween upon pivotal movement of said plates out of the position in which the curls may pass the lugs.

2. A hinge comprising, in combination, a pair of hinge plates, a pintle rigid with one of said plates, pintle-engaging curls carried by the other of said plates and disposed for axial sliding and pivotal movement relative to the pintle, projecting means on the pintle-carrying plate arranged to engage said curls to prevent said axial movement and to support said plates in several relative axially shifted positions, said curls having recesses therein to permit passage thereof past said projecting means as the plates are shifted from one to another of said positions.

3. A hinge comprising, in combination, a pair of hingeplates, a pintle rigid with one of said plates, pintle-engaging curls carried by the other of said plates and disposed for axial sliding and pivotal movement relative to the pintle, projecting means on the pintlecarrying plate arranged to engage said curls to prevent said axial movement when the plates are in one of several relative axially shifted positions, said curls being partially open to provide a recess therein through which said projecting means may pass when said plates are shifted axially while in faceabutting relation.

4. A hinge comprising, in combination, a pair of hinge plates, a pintle rigid with one of said plates, a curl carried by said other plate and embracing said pintle, said curl being arranged to slide axially of said pintle and having an arcuate recess therein, and a projection on said pintle-carrying plate fashioned to engage said recess to prevent said axial movement, said curl having a second and transversely extending recess communieating with the first mentioned recess to permit disengagement of said projection from said arcuate recess in one relative pivotal position of the plates.

In testimony whereof, I have hereunto alfixed my signature.

THERON T. CHAMBERLAIN.
