SASH-FASTEN ER.

fiPEGIFIGATI ON forming part of Letters Patent No. 540,149, dated May 28, 1895. Application filed December 29, 1894- Serial No. 533,325- (No model.)

To all whom it may concern.-

Be it known that 1, DAVID ARTHUR CRIOH- TON, a subject of the Queen of Great Britain and Ireland, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvementsin Looks or Fastenings for Window-Sashes and Sliding Doors, the

same being applicable to other purposes, of which the following is a full, clear, and exact description or specification, reference being had to the accompanying sheet of drawings, forming a part hereof.

My present invention relates to an appa ratus for fastening the sliding sashes of windows, or sliding doors, or other analogous sliding appliances.

The object of the invention is to provide an improved sash lock sure, positive and effective in action, and comprising a minimum number of partsto accomplish the ends in view.

The invention consists in certain novel features of construction and in combinations and arrangements of parts more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings, Figure l is an inside elevation of a portion of the window and window-casing, showing my improved locking apparatus applied thereto. Fig. 2 is a side elevation of the same, showing the window-sashes and glass in section. Fig. 3 is a horizontal section on the line a a, Figs. 1 and 2. Fig. 4 is a vertical section on the line b b, Fig. 6, of thecasing and lock shown in its place therein, the sliding bolt of the look, also the operatinglever, spring, and ratchet-bar, being shown in elevation. Fig. 5 is a front elevation of the lock, showing the interior operative parts in dotted lines. Fig. 6 is a section of two of the said locks, drawn full size, in the relative. positions which they occupy in the upper and lower sashes, also showing the key which passes through the holes in the levers of both locks simultaneously. Fig. 7 is a cross-section showing the shape of that part of the key which enters the holes in the levers of each of the locks. Fig. 8 is a front elevation of a portion of the ratchet-bar shown in side elevation, Fig. 4.

In Figs. 1, 2 and 3 the upper sash frame is marked A, and thelower sash frame is marked B. The sash frames are of ordinaryconstruction and fitted to slide in the casings O.

The lock for controlling the opening of the upper sash is marked D, and the lock for controlling the opening of the under sash is marked E. Both locks are of the same construction, which construction is shown more particularly in Figs. 4, 5 and 6. The lock which controls the upper sash is placed with its movable bolt F, uppermost and the. lock which controls the lower sash is placed with.

its movable bolt G, lowermost.

The look as shown in Figs. 4, 5 and 6 is constructed with one of its side plates removable and which is held to the body of thelock by the screws 0, passing through the side plate and entering the corresponding screw holes in the opposite side plate, after the manner of a common look.

In the upper part of the lock casing there is situated a rectangular transverse way or recess d, open at its outer end and under side, for receiving the bolt, which is one of the bolts marked respectively F, and G, Fig. 1. In Fig. 4 the bolt is marked F, and its outer end protrudes into and engages with the adjacent tooth of the ratchet bar H, as shown.

In the lower part of the lock casing shown in Figs. 4 and 5, a cylindrical barrel I is situated and carried in the bearings in the two sides of the lock casing. From this barrel there projects upward the lever .I, which onters the recess K, formed in the lower part of the bolt F, and around this barrel there is also fixed a coil of wire spring L, the upper part of which enters a notch also in the lower part of the bolt F. This spring L, hasin turn its lower part or tail resting against the bottom plate of the lock casing, so that the upper tail of the spring L, at all times forces the bolt F, into the ratchet tooth adjacent to it. The entire lock is fixed in the casing by the screws M, as shown.

Through the center of the barrel I, to which the lever J, and the spring L, are attached as hereinbefore described, there is formed a circular orifice with a notch or tooth 1 project ing inward from one side of it. The inner end of the key N, Fig. 6, is shaped semi-circularly so as to fit into this orifice, and one edge of itsrflaasid-ebearsvagainstrthe-said pro-j jectingpieceor notchq-so that whe-n thekey N, is turned in one direction, it operates the lever J, so as to withdraw the bolt F, from the ratchet notch in the bar H, wherein it is engaged and thereby unlocks the-lower sash,

thus enabling the sash to be lifted to any desired point. After having unlocked the lower sash, the turning of the key N, in the oppo. site direction then unlocks the upper sash,

thus enabling the upper sash. to be lowered to any required extent. By'allowing. the key"; N, to return to its normal position, the holes I, respectively in the locks of the upper and lower sashes which are situated in alignment with each other, admits of" the key N,*if desired to be Withdrawn from the locks-yer it may be allowed to *remain -therein permanently;

The ratchet bars H, 'Figs.-4 'and- Sffltted into-the wind'ow sa-shes are formed with-a flange O, projecting from one side thereof, as shown, the object'of which is to prevent a burglar or other pers'on'from' sliding in, or-in'-' sorting a piece of th'iniron or'otherinstr'u ment, which in looks of this class as hitherto 1 constructed, can beused to force back the bolts, thus enabling burglars to open' the windows farther and to pass-"through windows. By means of the flange O, such thin piece of metalor oth'ermaterial inserted between the sashframe and the window-casing, can only be forced-against the lo'wer or upper-sideofi.

the bolt .F, and 'thustheforcing endwiseofthe bolt by such act or "artifice is -renderedimpossible. The ratchetbars-"H may be formed without the flange" Og providihg the groove iirthe window casing is "ma'de -sufficiently deep to allow the' bar" H, to lie therein far enough away from the casing so as to enable'the bolt F, to pass thereinto, in the po sition corresponding to that shown in-Fig.4;

Although I have, on the annexed 'sheet of drawings, shown my sash or'slidingdoor look ing apparatusas applied forlocking an upper and under sash by means-of the said locks being fixed in the window casings and-the ratchet bars fix'edin the sash frames, yetrI desire it to =be-understood that the relative positions of the locks and the ratchet bars" maybereversed that is to say,;the-locks may each be placed respectively in the upper and under sash frames and the ratchet bars may be respectively fixed in the window casings, and in this case the teeth in the ratchet bars are by preference made after the manner of an ordinary square tooth 'rack,'while the sliding bolts of the locks are also made with their outer en'ds'so as to fit into the space between said teeth. When the locks are placed in the sash frames and the ratchet bars in the window casings,it follows that-the locks must be operated independently of each other, in place'of' simultaneously as hereinbcfore described when they are placed in alignment in the window casings. 1 It is also to be-understood that-in place of apply ing the two locks as' her'einbefore described for locking the two sashes of a-'wind'o'w or the two halves of a double sli-dingdoor, one of such locks, with its corresponding ratchet bar and operating key,'may be'used for locking such single sash or door.

Having now described the nature of my said invention-and tl1e mannerof carrying the sameinto practical-effect, whatl consider new and'original, and therefore claim as theinvention to be secured to me-by LettersPate'nt, isas follows-z The lock comprising a rack, in combination with a case having the transverseway near one end thereof open at the outer'end andinnerside, the reciprocating bolt in said way, th e rotary'barrel journal'ed in the opposite end-oh thecaseuto rock in a plane parallel with the throwof' the bolt and provided-with to an arm extending longitudinally of the case and loosely'engagingthe bolt to throw the sa-me,the interior of thebarrel formed to receive an operating key, and a spring-in =the caseyieldin'gly forcing the bolt outwardly, substantially as described.

, In testimony whereof I have hereunto set my signaturein presence of two subscribing witnesses;

DAVID ARTHUR (BRIGHTON.
