ROBERT B. HUGUNIN, OF NEW HAVEN, CONNECTICUT.

SASH-LOCK AND STRIKER.

SPECIFICATION forming part of Letters Patent No. 763,980, dated. July 5, 1904.

Application filed February 19, 1904. Serial No. 194,451. (No model.)

To all whmn it may concern:

Be it known that I, ROBERT B. HUGUNIN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Lever Sash-Locks and Strikers Employed Therewith, of which the following is a specification.

My invention relates to improvements in that class of sash-locks applicable to the sashchannels of the frame and to strikers employed therewith. One look, with my improved striker, (constructively adapted for and employed in connection with weights or sashbalances,) for each sash enables the self-locking of each sash independently on closing, and when opened within the length of the striker for safe-locked ventilation the sash closing locked without unlocking cannot be unlocked or forced open from the outside without breaking the window. By removal of sash-stops the strikers are applied and removed without removing the sash from the frame. From above the rear sash when lowered and below the front sash when raised the locks are applied and removed without removing the sash or stops.

The objects of my invention are, first, through the rear-extended hook-formed pivotal bearings on each side near the front end of a locking-tongue lever, (see Figure 5,) in connection with corresponding bearings for same on sides of opening in face-plate, (see Fig. 3,) I prevent, by means of the hook, the lifting of front end of lever-plate and consequent disconnection of locking-tongue plate from faceplate of lock by pressure on the upper sash acting through striker and tongue of lock; second, through the construction of the upper and lower locking-surfaces of the lockingtongue with curves preferably radiating from pivotal center (see Fig. 5) the locking-tongue is held from disconnection with striker and upper sash from being unlocked by clownward pressure exerted through this sash and friction between the locking tongue and striker is prevented, as in looking and unlocking the sash; third, by the construction of stem of lock-handle on a forward angle, preferably of twenty-five degrees, from face-line of plate, extended to pass the sash-stop, (see Figs. 1, 2, and 6,) thence receding in opposite direction I avoid furnishing bearing-surface on the handle for the hooking of a wire and the unlocking of the sash from the outside between the meeting-rails, as when the sash is left open for safe-locked ventilation; fourth,by means of a striker employable with sash having weights or balances constructively adapted for mortising into the side edge of the sash having a face-plate of less width than and coverable by the regular half-inch stop when applied, the striker-plate having on one side preferably two locking tongue traversing bars and one butting-bar extending around the end of the plate, with openings between the bars to admit the locking-tongue the full width of the plate, (see Figs. 7 and 7,) I employ the full width of striker-plate and depth of mortise in the sash for the working of the locking-tongue and prevent through shrinkage or loose-fitting sash exposure of striker or mortise outside the stop covering same when applied. I attain these objects through the mechanism illustrated in the accompanying drawings, in which Figs. 1 and 2 are rear and front elevation views of my improved sash-lock embracing features of my invention-the hook-formed pivotal bearings B D, the radially-curved locking-surfaces of the tongue G, the angleprojecting handle-stem Ealso a view of a section of sash-frame M, showing lock applied to same, and stops NO. Figs. 3 and 4 are rear and front plan views of face-plate A and lock. Figs. 5 and 6 are elevation views of locking-tongue lever and lock having my improvements and showing handle-stem E projected from face-plate on a straight angle through stop N O instead of a curved, as shown in Figs. 1, 2, and 5. Figs. 7 and 7 are views of my improved strikers for sash with weights or balances. Figs. 8 8 are views of modifications of my improved strikers for sash without weights or balances; Fig. 9, a view of a modification of my improved striker for locking the sash from movement in either direction. Figs. 10, 10, and 11 are views of my modified forms of strikers applied to side edge of sash. Fig. 12 is a coiled compression-spring employed with lock. Fig. .13 is a right-hand side section view of a sash-frame, showing my improved locks applied to upper and lower sash-channels and stops N O. Fig. 14 is a side and sectional elevation view of upper and lower sash, showing my improved strikers applied to the side edge of same with reference to the tongues of the applied locks shown in Fig. 13, the dotted lines showing the connection between same as when the sash are closed locked, also shows position of sashcord R on the lower sash with reference to the applied striker on same sash.

Similar letters refer to similar parts in all the drawings.

A is a face-plate (see Fig. 3) showing leveropening a, lever-bearing b, spring-seat e, screw-holes (Z (Z, and hook-holding bearingpivots B B on each side of opening a; B B, my improved rounded locking-lever pivots on each side of lever-opening a in plate A; C, locking lever plate provided with my improved rear and downward projecting hookformed pivotal bearings D D, by means of which and the bearings for same on plate A the locking-tongue lever is movably and removably connected and secured from lifting disconnection through downward pressure exerted on same through locking connection with upper sash, acting through the striker and locking-tongue to lift outwardly the upper or pivot end of the lever-plate; .E, stem of the lock-handle, constructed on the plate C and projecting therefrom at an angle, preferably of twenty-five degrees, from face-line of plate through the sash-stop N or division-strip O, (see Figs. 1, 2 and 6,) thence receding in an opposite direction at a sufficient angle to prevent the unlocking of the sash from the outside between the meeting-rails with a wire, as when the sash are left opened for safelocked ventilation. This angular construction of lock stem and handle enables the location of handle near the longitudinal center of the face-plate A, thereby giving the least radial curve from the pivotal center for the movements of the handle in operating the tongue of the lock.

F is a lock-handle extended rearwardly at an angle with handle-stem E, as and for the purposes before stated; G, the lockingtongue of the lock, operated by hand and spring pressure, having radially-curved front and rear locking sides, the curves having, preferably, a radius extending from center of pivotal bearings B D, (see Fig. 5,) by means of which the tongue is pressed back free from friction contact with striker in locking and unlocking the sash, and by means of the curve on the front or upper side of the tongue the latter connot be forced back and disconnected from the striker and the upper sash become unlocked by a downward pressure exerted through this sash. The upper front or sashtraversing surface of the tongue 1 preferably f extending around the plate 72 f" extending around the end of plate.

construct nearly flat, for a short distance following the upper curve radius-line, (see Fig. 5,) enabling the tongue when pressed back, as on closing or opening the window, to freely traverse the sash.

H is a coiled compression-spring employed with lock-handle in operating the tongue of the lock; 1, stop projection on rear end of locking lever C, employed in connection with the stop on plate A; J, spring-arm extending from plate C, having spring-seatc, between which and spring-seat e on plate A is interposed the spring H, by means of which and pressure from the hand on 'the lock-handle F the locking connection and disconnection with my improved striker is obtained, as in locking and unlocking the sash.

K K are my improved self-locking tonguetraversing locked ventilating strikers for lower and upper sash, with weights or sashbalances, in construction consisting of a faceplate ]t, having on one side, preferably, three locking-bars g g 9", two traversing barsff, and one end pressureresisting or butting bar (See Figs. 7 and 7; same applied, see Fig. 14.)

g is the locking-bar when the sash is closed; 9, when the sash is left open for safe ventilation; 9, for extreme safe-locked ventilation. The traversing bars are necessarily constructed thin to provide space for the securingscrews between same and edge of the plate. This location of the fastening-screws insures greater strength to the necessarily-narrow face-plate 72/ than would be the case if located between the bars. The arrangement of the bars permits the closing of the sash, hung with weights or balances, locked, the tongue of the lock freely traversing same in closing without unlocking. The butting-bar end of the striker f, resting against the wood at end of mortise, while effectually resisting pressure to force locked sash open from the outside, also enables the sash to furnish a traverse over this bar in closing if opened beyond the striker-plate. (See Fig. 14:.) To facilitate the adjustment between the closed lockingbar 9 and the tongue of the applied lock, a screw-slot is provided in striker-plate 71/.

L L L are modifications of my improved striker for holding and locking sash without weights or balances, are applied to the side edge of the sash by mortising, (see Figs. 10, 10, and 11,) and covered when applied by the sash-stops. In construction the L L form consists of a face-plate h, one tongue-traversing bar f and one locking-bar g, the traversing bar f not being employed for locking purposes (see Figs. 8 and 8) and the butting-bar The L modification consists of a face-plate it,

two locking-bars g g, and two butting endbars f f and is applied as above stated. This modified form of strlker locks the sash from movement in elther direction and is especially adapted to application to lower sash to secure same when opened for safe ventilation.

M is a right-hand section of a sash-frame, Fig. 13, showing my improved locks applied to sash-channels for upper and lower sash; also sash-stops N and 0, lower sash-channel N, upper sash-channel O; P P, sections of upper and lower sash, showing my improved strikers applied to side edge of same with reference to the tongues of the applied locks, shown in Fig. 13 connected by dotted lines, as when the sash are closed locked; R, sashcord of lower sash.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In combination with a sash-lock, having a face-plate and locking-tongue lever pivoted thereto, operated by hand and spring pressure, the locking-tongue lever-plate provided on each side near the upper end, with con cave, hook-formed pivotal bearing-surfaces, embracing on the rear side, more than the vertical or longitudinal halves of the pivots, employed in connection therewith, to prevent the disconnection of the pivotal parts, through the workings of the lock, substantially as herein set forth.
