SASH LOCK.
APPLICATION FILED 001124, 1917.
WILLIAM FREMONT BARGER, OF NORWOOD, OHIO.
sA'sH-Loox.
Specification of Letters Patent.
Patented Feb.l24, 1920.
Application filed October 24, 1917. Serial No. 198,208.
To all wLof/a it may concer/n: v
Be 1t known that I, WILLIAM F. BARGER,
a citizen of the United States of America,
and a resident of Norwood, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Sash-Locks, of which the following is a specication. I
This invention relates to sash-locks in which provision is made to not only normally lock both sashes of a window when completely closed but to couple and securely lock both of them when in partly open position or relation, although not sufficiently open to permit undue entrance of an intruder from without, and it relates, as well as consists, more particularly, to and in an improvement on the lock couplingor link device for which United States Letters- Patent No. 1,171,016 was granted to me February 8, 1916, such improvement being but one carrier-hook member and a sectioned rod that may be folded into small compass and thus not so .noticeable as the rod of said patent.
In the accompanying sheet of drawings Figure 1 is an outside elevation showing the lock closed in connection with a fragmentary portion of the alined or closed meeting-rails, and with the glass shown in the lower sash only; Fig. 2, a plan view of the same; Fig. 3, ak cross-section taken on the dotted-line m, of Fig. 2; Fig. 4,' a rear elevation, omitting the glass from the upper sash, and showing the lock-proper released but with its folding or expansive, multiplelink coupling device partly extended so as to allow for the partialv opening of the lower sash but still locked against further undue opening from the outside; Fig. 5, a plan view of the lock-member that is mounted on the meeting-rail of the upper sash` showing my improved multiple-link coupling with the detent or latch swung open ready for the expansion of the said coupling and the partial raising of the lower sash; and Fig. 6, a detached perspective view of the vertical multiple-hook carrier-member of the extensible or sectioned lock-coupling in normal position at the outer end of the uppermost link of the three links that form said extensible lock-coupling.
1 indicates the lower sash and 2 the upper sash of a window, fragmentary portions only of each being shown, and 3 indicating the lower cross-bar or meeting-rail of the upper sash having a sheet of glass 4, and 5 further indicating the upper meeting-rail of the lower -sash and also supplied with the usual sheet of glass 6.
The lock-proper for the said meetingrails, when they are in full locking-alinement and bothsashcs closed, is composed of a pair of interlocking-members, the one on the meeting-rail of the lower sash l having a base 7 a spring-controlled latch-member 8 pivotally-mounted on said base 7, said latch-member 8 having an inclined rib or raised cam-edge 9, an upper'overhangingarm 10, and a manipulating-handle 11, and the other one of said interlocking-members being provided on the meeting-rail of the upper sash 2, duly alining with the firstnarned member and having a base or block 12 secured on the meeting-rail' of the upper sash 2 to aline with the base 7 on the adjacent meeting-rail, an overhanging or lateral ylatch-arm 13v projecting from the upright arm 13b of an eccentric or cam base 14 that, in turn, turns horizontally on a pivot or pin 15 on the elevated portion 16 of said base or block 12, all as best shown in Figs. 1. 2 and 3. An upright pin 17 extends from the said elevated portion 16 of the block 12 t0 form a stop for limiting the back stroke or turning movement of the cam 14 that carries` the latch arm 13.
A multiple-link, extensible connection or sectional coupling device is used by me inv providing for the partial opening of the sashes and still remain locked against intrusion from the outside. This extensible coupling device is composed of alower link y18 pivotally-mounted at 19 at its lower end in the base or block 12 on the meeting-rail 3 ofthe upper sash 2 and having a horizontal stop 18a (Figs. 2, 4 and 5) projecting from the elevated portion 16 of the block 12; a main or long middle link 20 pivotally connected at 21 at its lower end to the upper end of the link 18 and provided at its upper end with a lug or stop 23 (the latter as best seen in Fig. 4) an upper link 24 pivotally-connected at 25 to the upper end of said main link 2O and limited in movement to a slanting position by means of said stop 23, (to avoid dead-center) and provided at its upper end with a horizontal stop 26 on its inner face, and a lateral hook-arm 27; and an upright auxiliary-arm 28 that is pivotally connected or swiveled at 29 to the upper or outer-end of said uppermost link 24 and is the releasing of the latch-membergS' fromVV the double-hook carrier-member Q8A is sufli- Y cient and the Jfolded links of the eXtensible further provided with vertical oppositelyextending hook-arms the lower one 30 of which hook arms is adapted to engage the raised cam-edge 9 of the latch-member 8 on the inner meeting-rail 5 when the sashes are locked, entirely closed or partially open, and the other or upper one 31 of which hookarms is adapted to engage the upper edge of the overhanging-arm 10. The auxiliaryarm 28 is shown in section inFigs. 3 and 5,
and forms a double-hook carrier-member for use 1n v'musing the multiple-link couplingrod to extended position i'or the partially open window and, also, to return said mul-r end of the lowermost link 18, the latch-arn'i 13 of the eccentric 14 is swung forward into engagement with the -upper face of said hook-arm 27 to prevent the yurifoldinu of the links and to maintain the sashes in closed and locked position. A horizontal auxiliaryarm 13a is provided on the eccentric lll in and serves to rest'on the mainlink .20 to prevent its rising when the sashes are closed and locked by means of the latch-member 8 on the meeting-rail 5v of the lower sash.
The horizontal kstop 26 onvthe upper link 24 forms a barrieragainst which the doublehook carrier-member 28 rests in upright position, secure against .further backward movement whenfthe sashes are closed and locked and, also, holds said member 28 iirin when the inclined rib or vraised cam-edge 9 of the latch-member 8 is turned'into locking engagement.
If the sashes are yto `loe thrown wide open coupling rest normally on the meeting-rail L3 of the upper sash, with thelatch-arm 13v in engagement-with the hook-arm 2T, ready for locking when the sashes are partly or wholly closed.
I claim A locking device for window-sashes, to
hold them in either full locked condition or partly open and the latter condition still locked against intrusion from the outside, and comprising a pivotal latch-member mounted on the meeting-rail of the lowersash and having an upper overhanging lateral-arm, a block on the meeting-rail of the upper-sash alining with the said latch-member and piovided'with a horizontally turning or swinging overhanging lateral-arm orlatch-member projectingfrom an eccentric or cam base, a stop on` said block for limiting-the rea-r or` outer moifement of the said last-named latch-member, an extensible multiple-link couplingpivotally vconnected at one end to the said block on the meetingrail of the upper-sash and havinga horizontal limiting-stop on the inner face of said block for the upward swinging or extending movement of the lowermost link of the coupling, a stop at the upper end of the middle orma-in 'link of the .coupling for limiting the upward swinging or extending movement of the uppermost link, a pivotalarm mounted at the outer ,end oi' the said y. uppermost link'and providednvith oppovertical alinement with the latch-arm 13' adapted to limittlie movement thereof and --normally support it perpendicularly, and a lat-eral hook-arm or stop provided on the outerend of thesaid uppermost link eXte-nding toward thefblock on the meeting-rail of the upper-sash to aid in lowering the main -link in closing the coupling and the window-sashes and, also, vto present a 'bearingvsurface for the engagement of the said horizontally-turning lateral-arm on Vthe said block to prevent saidsashes parting out of locked condition when closed.
VVILDIAM` FREMONT BARGER.
