SPECIFICATION forming part of Letters Patent No. 294,474, dated March 4, 1884.
Application filed January 15, 1S`4. (No model.)
To a/ZZ whom, it may concern: l `Be it known that I, ELEAZER KEMPsHALL, of New Britain, in the county of Hartford and .State of Connecticut, have invented a certain new and useful Improvement in Sash-Fasten ers; and Ido hereby vdeclare that the following specification, taken in connection with the drawings furnished and forming a part of the same,is a clear, true, and complete description of my invention..
My said improvement relates exclusively to that class of sash-fasteners which embody a pivote( nsweep 7 for engaging with a keeper, and on the rear end of said sweep a pivoted gravity-latch operating in a vertical plane, so that by its own weight it will 'drop and engage laterally with either of two suitable shoulders on the bed-plate, on which the sweep is mounted, for holding it-in either its locked or unaddition thereto, it.contributes,'for the first locked position. g
rlhe object of my improvement 1s to so conv trol the gravity-latch that when the sweep is in its locked position it will be practically impossible for said latch to be so jolted out of its proper position that the sweep can be thrown around and unlocked, as by the use of a knifeblade applied in a manner well known. I accomplish this end by employing, for the first time, with the sweep, in a fastener of this class, a spring which so exerts its force as to throw said sweep from its locked to its unlocked position, and therefore, when it is in-its locked position, the gravity-latch, by the power ofthe spring, is held laterally against its shoulder so rmly that it cannot be jolted or thrown from its proper position. In other classes of sash fasteners pivoted sweeps have been provided with springs which throw them from` their locked to their unlocked positions; but they have always heretofore been employed either with rotating-spindle spring-latches or spring-latches which longitudinally reciprocate, and therefore in those fasteners the sweepsprings in no manner modify or affect the operation of said catches, whereas in my improved fastener said sweep-spring performs its usual and well-known functions, and, in
time, to the security of the fastener by controlling the gravity-latch.
the usual vertical side notch or shoulder, e,
with which the gravity-latch engages laterally for'holding the sweep in its locked position, as when in engagement with its keeper plate, and the similar notch or shoulder, f, usually provided in fasteners of this class may also be employed in my fastener, although itperforms no very important service, inasmuch as the sweep is maintained in its unlocked position, as indicated in dotted lines .in Fig. l, by reason of the spiral spring g, which encircles'the pivot h of the sweep, and is under sufficient tension to prevent said sweep from swinging toward the keeper, except when specially manipulated for that purpose. As hereinbefore stated, said sweep-spring in my fastener not only performs the old and well-known service of throwing the sweep away from the keeper when permitted so to do, 'but it also performs the novel service of forcing the grav ity-latch sidewise-into 'rm and reliable contact with the shoulder e whenever the sweep occupies its locked position, and therefore a blow-as with the hand or a cushioned hammer-delivered against the outer surface of a sash on which said fastener has been applied cannot jolt or throw said latch from its proper engagement with said shoulder. The gravitylatch, being thus firmly confined, renders it practically impossible for the sweep to be thrown away from the keeper, except said latch be specially manipulated, whereas if Havingthus described my invention, I claim against its shoulder when said sweep occupies as new and desire to secure by Letters Patentits locked position.
The combination ofthe notched or sl1onll ,1 f 4 y dered plate, the sweep pivotcd on said plate LLEDR KDMPSHALL' 5 and provided with :n gravitylatcli, and the XVit'nesses: sweep-spring, substantially as described, l LYMAN S. BURR, whereby the gravity-latch is firmly held i JOHN P. lmTLliT'i.
