WINDOW-SASH LOCK.

Specification of Letters Patent.

Eatenteaiien. is, icio.

Application filed April 3, 1916. Serial No. 88,630.

device of this character for a window such as is shown in my Patent No. 1,138,392, in which the sa-shes are adapted for vertical travel, as usual within the sash-frame, and wherein the sashes may be readily swung in a horizontal plane 'to open position in the room, thus permitting free ventilation and the ready cleaning of the windows.

The

dow. as shown in Patent No. 1,138,392, grantn ed to me May 4, 1915.

Another object of my invention is to provide a novel fastener for holding` the sashes shown in my -aforesaid patent against turning movement on their horizontal pivots, which fastener permits the sash cord to pass through the same and is constructed to slide within the groove between the guide and parting strips of the window.

A further object of my invention is to produce a generally improved locking mechanism of this class which will be eXceedingly simple in construction, cheap to manufacture, eflicient in use, easily operated, and much better adapted for its intended purposes than any other devices of the same character.

With these and other objects in view 4my invention comprises the combination and arrangements of the after described, shown in the accompanied drawing and specilically pointed out in fthe claims.

ln the drawings:

Figure 1 is a detail horizontal section of a window embodying my invention.

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a detail vertical sectional view through a portion of a window frame and two sashes showing the pivotal mounting of the sash.

Fig. 4 is a sectional view of one of the primary object of my invention is to produce an improved sash lock for my win-l various details as hereinwindow sashes joint.

f Fig. 5 is an enlarged detail view of my lock inverted, the parts being separated.

The reference numeral 1 designates an ordinary window frame provided with the usual sash grooves 2 2, between the intermeshowing the weatherproong diatel vertical parting strip 3 and the inner andouter guide strips 4 and 5, respectively, which are tted to the window frame in the usual manner.

' The lower and upper spectively, being of the description of one will sash 6 is pivoted sashes 6 and 7, resame construction a suffice. The lower at the bottomrail to a slide 8 whereby it may, under proper conditions, be swung on its pivot into the room to facilitate the cleaning thereof, as shown in my aforesaid patent. i

In order that there may be a weatherproof joint between the sash and its slide 8 l secure to the slide a metal strip 9 having its outer marginal edge 10 rebent to form a socket into which the outer metal strip 11, secured to the side stiles of the sash, projects thereby forming a weather-` proof joint. Y

My improved lock 12 comprises two members 13 and 14 which are connected by a combined pintle and locking bolt 15 having a knob 16 secured thereon. The locking bolt consists of apintle 15 and a locking member 17 integrally formed therewith.

The member 13 is adapted to be secured to the upper rail of 'the lower sash 6 by means4 of screws 18 or the like, while the member 14 is constructed to overlie the slide 8 and extend into the groove 2 whereby the lower sash 6 is locked against swinging' movement. This member with a cutout portion 19 to accommodate the usual sash cord 20.

The member 14 is provided with two pintle eyes 2Oa and 21 which form partof the hinged fastener, the eye 20a being bent back upon itself -to form an eye to accom modate the pintle 15, while the eye 21 is bent back in a horizontal plane substantially par allel with the member 14, forining a slot or guide-way for the portion 23 of the locking bolt 15, as shown in Fig. 5,.

The upper sash 7 is provided with a recess 24 near its outer marginal edge which is adapted to receive the end portion 25 of the locking bolt 15, whereby both sashes are Enron.

edge of thel 14 is provided held against movement. This sash 7 may be provided with a series of recesses 24 in order that the same may be locked in either varied open or closed positions.

TheV parting strip 3 is provided with a recess 26 on its inner side thereof'which is adapted yto receivethe end portion 27 of the locking member'17, whereby the lower sash is locked against movement. It isunderstood that this parting strip may be provided with a series of recesses 26 corresponding to the recesses 24 in the upper sashl so that the sash maybe locked in any position desired. By this construction 1t will be seen that my locking bolt locks both the upper and lower sash in any position desired.

On the top rail of the upper sash I provide a hinged fastener 28 as shown in Fig. 1, which is similar to the locking member 12 except that the pintle is not removable. The member 29 of this fastener 28 is adapted to be secured to the sash by means of screws or the like, while the member 30 is constructed to overlie and cover the slide of the upper sash of the window, and project into the slide-way 2, whereby the sash is held. against movement on its pivot which is located at the bottom'rail, as shown in my Patent No. 1,138,392. The member 30 is provided with a cutout portion 31 to accommodate the usual sash cord 32.

When it is desiredto clean the lower sash the locking bolt 15 is pulled out of position, as shown in dotted lines in Fig. 2, thereby moving the locking member to a position under the member 1.4L, the shape of the member 21 permitting this movement', and then turned to the right as indicated by the arrow which turns the member 14 upwardly, whereby the sash may be swung inwardly into the room.

In order to open the fastener 28 of the upper sash so that the same may be cleaned I provide a key 33, asshown in Fig. 3, which is adapted to fit under the member 30 through the cutout portion 31 whereby the member 30 is raised to unlocked position and the sash may be swung inwardly in the usual manner.

I have provided another means for opening the fastener 28 of the upper sash instead of using the key 33, which consists of a small knob 34 secured to the upper face of the member 30, whereby the fastener can be opened more easily.

I claim:

1. A sash lock comprising two hinged members each having the usual pintle eyes, one of said eyes` being provided with a slot in one of its walls, a pintle securing said members together, and a locking member carried and operated by said pintle, said locking member being constructed to slide in the above mentioned slot.

2. A sash lock comprising two hinged members, each having pintle eyes, one of said eyes being provided with a slot in one of its walls, a pintle securing said members together, and a locking member comprising two arallel spaced bolts carried and operated y said pintle, said locking member being constructed to slide in the above men-v tioned slot.

3. A sash lock comprising two hinged members each having pintle eyes, a pintle securing said members together, one of said members having a cutout portion to accom modate a sash cord, and a locking member carried and operated by said pintle.

1. A sash lock comprising two hinged members each having pintle eyes, a pintle securing said members together, one of said eyes being provided with a slot in one of its walls, one of said members having a cut-out portion to accommodate a sash cord, and a locking member carried and operated by said pintle, said locking member beingconstructed to slide in the above mentioned slot.

5. A sash lock comprising two hinged members, a pintle securing said members together, and a sash locking member comprising two parallel spaced bolts carried and operated by said pintle.

6. A- sash lock comprising two hinged members each having pintle eyes, a pintle securing said members together, one of said members having a cutout portion to accommodate a sash cord, and a locking member comprising two parallel spaced bolts carried and operated by said pintle.

7 In a lock for a window sash which is pivotally mounted at its lower end to a slide in a window frame, said lock comprising two hinged members, one of which is adapted to project within the slideway of the window frame and is provided with a sash cord recess, the wall of one of the pintle eyes being provided with a slot, a pintle pin securing said hinged members together, and a plurality of parallel bolts projecting from one end and in the direction of the length of said pintle pin and beyond the hinged mem ber of said bolts and adapted to have locking engagement with a sliding sash and a stop bead.

In testimony whereof I affix my signature in the presence of two witnesses.
