casnivrnn'r FASTENER.
Application filed. March 26, 1928. Serial No. 5364;359.
My invention relates to devices for fastention in its window frame, so as to maintain the same in tlght weather-proof relation ex- 5 ceptwhen said device is released to permit tinually tend to loosen the'rivet holding the the sash to be swung open, and my device, is
of what is known to the trade as the earn handle class, i. e., including means for effecting a cam action whereby the sash is drawn into tight relation with the window frame.
7 Ordinary devices for the purpose aforesaid, include a handle pivoted upon a. rivet WlllCh-IS mtended to be a fixture 111 a base plate pr1-.
marily separate and distinct from both the sash frame and the window frame but having openings, in said plate, .through which the plate may be connected with the sash frame by screws or rivets. In all such devices, the stresses incident to closing the sash and holding it in closed position are such as to conhandle to the plate, and the screws or rivets holding the plate to the sashfra'me. More'- over, the movement of the handle is only lim ited by a projection on said plate, which'is independent of both the sash and the handle" and does not prevent the handle from being turned into such position that it interferes with the opening movement of the sash when the handle is unfastened and the sash otherwise free to be opened. Ordinarily,'such devices are unyielding and are so constructed and arranged that although primarily firmly operative, they rapidly d-eteriorate'until they are loose and practically inoperative.
Therefore, it is the purposeand effect of my invention to provide a fastening device for the purpose above described adapted to maintain the sash frame closed in its window frame under resilient pressure and to maintain itself continuously in operative relation.
As hereinafter described, my invention is so constructed and arranged that the handle pivot is carried by the handle and extends between parallel leaves on the handle which resiliently embrace between them a pivotal support which is in unitary or integral relation with the sash frame; so that the stresses incident to closing the sash and holding it closed are resiliently borne by the pivot member of the sash without tendency to loosen the pivot in the handle. Moreover, the bightbetween said handle leaves is so shaped in relation to the pivot member on the sash frame as to limit the movement of the handle to and from operative position; without requirement of the projection or other means for that purpose as in the old devices aforesaid; so that it is. impossibleto place the handlein position to interfere with the opening movement of the sash, when it is released.
1,10 ,560 T: QFF ICE-J- My invention includes the various novel features of construction and arrangement hereinafter, more definite-1y specified.
In said drawlngs; Fig. I is an inside eleva tion of a casement's ash, and window frame,
embodying my invention.
F ig. II is a fragmentary plan sectional View of the sashframe and window frame,
taken on the line II, II in Fig. I, and showing a plan view of the fastener in closed position.
FigIII is a fragmentary elevation of the sash, with the handle insect-ion, taken on the line III inFig. II.
Fig. IV is a sectionalview of a w-indow frame and sash frame showinga modified form of pivot member on the latter.
-Fig. V is a fragmentary elevation of the structure shown in Fig-IV. 3
. Fig. VI isa fragmentary verticalsectional I view taken on the lineVIin Fig. IIv and. showing the closed relation of the movable cam arm on the sashv frame with the stationary cam bloclron the windowframe.
In said figures; 1 :is the window frame which is rigidly set in the building wan in any convenient manner, and'is provided with r V hinges 3' by which it is pivotally. connected with the sash frame 2 which isthus mounted thereon to swing outwardly.
In the form of my invention shown II and III, both the windowframel and sash frame 2 are formed of rolled steel bars 1 of the same cross section, including centralness as the flange 9 on said frame 2 and offset. inwardly, with respect to the window frame, in integral relation with th'e -'i-'riner edge-of said flange 9. Such abearing member ,8 is conveniently formed from a primarily se'pa substantially water-tight, at I rate plate whichis fitted'inthe frame 2 where l a portion of the flange '9 has been removed, and is welded in flush-relation with the flange 9 atthe places indicated by the dotted lines in Fig. III. j i
As shown in Figs. IV and V, the pivot hearing member 8 on the sash frame 2 is formed.
I of a primarily separate plate which is fitted in place of a portion of the flange 9 of the frame 2 which is cut to receive it and is welded in flush relation with said flange 9at the oints indicated by the dotted lines 11 in Fig. V. However,the outer end of such plate is bent I parallel with the web ofthe frame 2 as indicated at 12 in Fig. IV and may be welded,
riveted or otherwise rigidly connected therewith. 1 w
In eaclrforn i of my invention above clescribed, the inner edge 1410f the pivot bearing nected by the bight 20 and have the primarily plane recess 21 between them, conveniently formed by a millingcutter so as to fit easily upon said pivot plate 8 However, the pivot screw. 23 which extends between said primarily parallel leaves 18v and19 and is the fulcrum pivot for said lever, extends through the smooth bearing 24 in the leaf 18 but is in screw I threaded engagement with thebearing 25 in the leaf 19 and is screwed tight enough to frictionally engage said. pivot bearing member, 8 on the sash frame 2 and prevent rattlingof the handle 17 in connection therewith. I find it convenient to lock said pivot screw 23 in adjusted position in .thehandle by j, means of the lock washer 26beneath the head of the screw which engages the latter and the opposite surface of the handle. leaf'or aw 18; However, saidlocl: washer 26 may be omitted if the screw 23 tightly engages the thread in the bearing 2*. In any case, the pivot screw 23 normally remainsiin stationary relation with the handle 17 and its adjustn'ientis not disturbed by any of the. stresses incident to the use of the fastening device.
Said handle jaw 18 carries the radially extendingcam arm 28 which may be prin'larily.
bent toward the window frauie 1 at an angle of about five degrees to the plane of said frame, and hasa rounded'surfac'e presented toward the window frame 1, as indicated at 29 in Fig. VI, so as to ride easily upon the cam block 30 which is conveniently formed of a bronze casting having rivet lugs 31 with V which it is rigidly connected with the window frame 1. 1
It is to beunderst'opd that the construction and: arrangement above described aresuch that when'the cam handle'17 is turned to the position indicated in dotted lines in Fig. I, the sash frame 2 may be swung upon its hinges 3 to open the casement; but, when the sash frame 2 is swung into closed position with respect to the window frame 1, as indicated in Fig. II; the handle 17 may be turned to the position shown in full lines in Fig. I and, in so turning, encounters the inclined surface 32 of the cam block 30 before it reaches the position shown in Fi VI and is only brought into that position by resilient flexure of the entire fastening structure including the pivot bearing flange 8; so that, in the positionshown in Fig. II, the two frames are resiliently clamped together in" water-tight relation.
Although I have shown the handle 17 asa f straight cylindrical bar; it may be made of any convenient form and be ornamented, and althoughI have found it convenient to make such handles of wrought steel, they may be made of other material, for instance, cast bronze, and although I have found it convenient to form the recess 21 by milling operation; it may be formed by drop forging or die casting operation, or otherwise.
Therefore, I do not desire to limit myself to the precise details of construction and ar-.
rangement herein set forth, it is obvious that various modificationsmay bemade therein without departing frointhe essential features of my invention, as defined'in the appended claims. T I l 1.
