SASH-FASTENER.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed ltovemberl 30, 1920. Serial No. 427,435.

f( 1o all whom it' may concern.'

e it known that l, STEFAN llIoJoiii, a citizen of Poland, residing at Detroit, in the coi'lnty of llVayne and State of Michigan, have invented certain new and useful lmprovements in Sash-Fasteners, of which the following is a specification.

rhis invention relates to certain new and useful improvements in sash fasteners` and has particular reference to a fastener supported on a window casing and carrying tensioned bolts for engagement with `upper and lower window sashes to hold the same in closed locked positions.

A further object of the invention resides in the provision of a sash fastener supported on a window frame and carrying a pair of independently operable tensioned bolts adapted for reception in sockets provided in the adjacent edges of the upper and lower window sashes to hold the sashes either in closed locked position or in various open immovable positions, thus permitting the window to be partially opened and so retained against unauthorized movements.

lith the above general objects in View and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accom panying drawings and claimed` In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a fragmentary horizontal sectional view through a portion of a window frame showing a latch casing supported.

thereon with projecting bolts holding the upper and lower sashes immovable,

Fig. 2 is a fragmentary side elevational view of a portion of the window frame showing the locking bolts for the sashes projecting from the frame,

Fig. 3 is a fragmentary view of the window frame showing the plun ger heads for shifting the locking bolts,

Fig. 4 is a detail sectional view showing the latch casing supported on the window frame with the tensioned bolts carried thereby extending into sockets formed in the edges of the upper and lower window sashes,

Fig. 5 is a fragmentary side elevational view of the upper Aand lower sashes with apertured face plates secured thereto,

front elevational Fig. 6 is a detail sectional view of the latch casing showing the tensioned sash engaging bolts and one of the plunger rods for .shifting one of the bolts, i`

Fig. 7 is a perspective view of one :of the sash base plates, and

Fig. 8 is a fragmentary perspective `view of the locking bolt and a portion off-the operating mechanism therefor.

Referring more in detail to the accompanying drawings there is illustrated `a sash fastener construction associated with a window framel supported in the wall .2, the frame 1 including a side wall 3 with the adjacent edges ot upper and lower sashes 4 and 5 slidably associated therewith and separated by the parti-ngstrip -6 with the, forward molding 7 holding the lower sash 4 in position. As shown in Fig. 5 the lower and upper sashes `4 and 5 have meeting rails Sadapted for engagement when the sashes are in their closed positions.

The edges of the sashes 4 and 5 adjacent the side wall 3 of the Window frame are slightly out away for the counter-sunk face plates 9 secured thereto by fastening devices 10 and having vertically alined oper ings 11 formed therein with overlyingflanges 12, the openings 11 in the face plates 9 registering with socketsl in the edges of the window sashes 4 and 5, into which openings sliding latch bolts are adapted to be projected to hold the windows in operative closed locked positions or partially open.

A latch casing 14 is disposed within the hollow window frame 1 and is secured to the side wall 3 of the frame by the fastening device 15. A pair of tensioned bolts 16 having tapered nose ends 17 projecting through the side of the casing 14 and through openings 18 in the frame wall 3 and through the openings 11 in the face plates 9 for projection into the sockets 13 in the window sashes. The detail latch construction is shown more clearly in Figs. 4,

6 and 8, a vertical pin 19 supported in the To retract the tension bolts from engage- 'ment with the window sashes 1 and 5, a

bell crank is associated with each vbolt 16, the bell crank being pivotally mounted with- 'in the casing as at 24; and having thel end of the leg biurcated as at 26 for inclosing the pins 27 projecting from the bolt 16, the other leg 28 having an operatingl rod 29 attached thereto with a press button BO'upon the outer end whereof, the two rods 29 of the Operating-devices tor the two bolts 16 slidably projecting through the front wall of the window frame 1 with the push button positioned exterior-ly of the window frame as shown in Figs. 1 and 2 while a iace plate 31 carried by the outer 'faceof the window frame provides a sliding guide for the push buttons.` y Y From an inspection of Fig. 2 it will be notedy that the tensioned bolts 1G are laterally disposedffor engagement with the upper and lower sashes respectively. VWhenv it is desired to release either 4of the window sashes, the desired push button 30 is operatedA to cause the rod 29 to move the bell crank and retract the bolt 16 through the casing against the tension of the adjacent spring arm 22 to remove the tapered end 17 of the bolt from the socket 13 in the window sash and the opening 11 in the sash plate'9.

By the' provision of this device, the window sashes may either be locked in closed positions or partiall opened and so retained against unauthorized movements.

While there is herein shown and described .the preferred embodiment of the present ing at their ends one side wall of the casing and said bolts to normally hold the bolts projected into sashv sockets, a bell crank pivotally mounted within the casing for each bolt and having a loose connection therewith, and independently operable devices for operating the bell cranks to shift the bolts. against the tension thereon to remove the same from the sashy sockets.

In testimony whereof I aihx my signature.

STEFAN WOJCIK.
