THOMAS J. DANIEL, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-HALF TO LOUIS C. DIEKIWIANN, OF SAME PLACE.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 459,676, dated September 15, 1891.

' Application filed February 13, 1891. Serial No. 381,304- -(No model.)

To all whom it may concern:

Be it known that I. THOMAS J. DANIEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in IVindow-Sash Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This is a device for locking the sashes by the actof closing them. A combination-tumbler device is used to prevent the unlocking 0f the sashes by any one unacquainted with the device.

The novel features are set forth in the claims.

Figure I is a front view of the device. Fig. II is a top view. Fig. III is a front view of the inner side of the outer meeting-bar. Fig. IV is a transverse section taken at IV IV, Fig. II. Fig. V is a transverse section taken at V V, Fig. II. Fig. VI is a longitudinal horizontal section taken at VI VI, Fig. I. Fig. VII is a longitudinal vertical section taken at VII VII, Fig. II. Fig. VIII is a longitudinal vertical sectiontaken at VIII, VIII, Fig. II. Fig. IX is a side view of the locking-pin.

1 is the outer meeting-rail, forming the lower bar of the upper sash.

2 is the inner meeting-rail, forming the upper bar of the lower sash.

3 is a metal plate let into the inner face of the bar 1 and secured in place by screws 4.

The plate has inclined recesses 5, down the inclined sides of which the ends of the springbolts pass as the sashes are closed. Directly below the inclined recesses are the bolt-holes 6, entered by the ends of the bolts as the sashes close. (See Figs. III and IV.)

The bolts 7 work in sockets 8, extending through the rail 2, the sockets being preferably lined with a metal bushing 9.

10 is the face-plate. sunk in the front of the rail. Thebolts have reduced shanks 7, extending through holes in the face-plate. S rrounding the shanks of the bolts are spiral springs 11, whose ends bear, respectively, against the heads of the bolts and the inner side of the face-plate and whose oflice is to push the bolts forward. The bolts are connected outside the face-plate by a cross-head 12, through which passes a spindle 13, that is between the bolts and parallel with them.

The spindle works in a socket 14, and is drawn inward by a spring 15, which surrounds it, and whose inner end bears against a cross-pin 16 at the inner end of the spindle. The outer end of the spring bears against the inner side of the face-plate. The spindle 13 has a cross pin that engages the cross-head as the spindle 13 is drawn outward and draws out with it the cross-head and the bolts to withdraw the heads of the latter from the holes 6 and allow the opening of the sashes.

18 is a tumbler-wheel, which turns on the spindle 13 as an axis and which is held to the face-plate by hooked lugs 19, that engage the edges of the tumbler, so as to hold it to the face-plate while all'owin g its free rotary movement. The tumbler has slots 20, extending radially from its central orifice, through which the ends of the cross-pin 17 may be passed when the pin and tumbler are in the proper relative position. The face-plate has similar slots 21 to allow the pin 17 to pass. The spindle has a head 22, that may turn freely thereon, but which may be locked thereto by a spring-catch 23, that is pivoted to the head and which is adapted to occupy a diametric recess 24 in the end of the spindle. The top of the face-plate has a mark or marks 25, and the head 22 and tumbler 18 have also marks by which the spindle and tumbler may be set in the position to allow the pin 17 to pass through the slots 21 and 20 of the face-plate and the tumbler, in which case the spindle cross-head and bolts may be drawn outward into the position seen in Fig. VI, in which case the sashes are unlocked. When the sashes are looked together, the cross-pin 17 is inside the face-plate and the spindle cannot be drawn outward unless the pin 17 is in line with the slots 21 and also the slots 20 of the tumbler.

The spindle and tumbler may be left in the position they have when the bolts are thrown forward in the actof locking the sashes. In this case the bolts may be drawn outward by a simple pull upon the head 22; but when it is desired to make the fastening more secure either the spindle or tumbler is turned, or both of them, and then the bolts cannot be retracted until the parts are returned to proper position, as set forth. lVhen the spindle is out of position for retraction, the spring-catch 23 may be lifted from its recess 25 in the end of the spindle and turned to one side, as shown by dotted lines in Fig. I, and then the head will turn freely on the spindle and the latter Will remain-at rest and cannot be set in position for retract-ion until the spring-catch has been again placed in the re;

cess of the spindle.

I claim as my invention 1. In a sash-lock, two spring-bolts '7, connected by a cross-head 12, a spindle 3, passing through the cross-head and turning therein, a face-plate traversed by the spindle and slotted at 21, and a pin 17, )rojecting, from the spindle and adapted to pass through the slot 21 only in certain positions of the spindle, substantially as set forth.

2. The combination of spring-bolts 7, working in one sash and engaging in both holes 6 in the othersash, a cross-head connecting the bolts, and a spindle turningin the cross-head and adapted to lock the bolts, substantially as and for the purpose set forth.

3. The combination, in a sash-lock, of bolts 7 and spindle 13, working in one sash and entering the other, the bolts being rigidly attached to a cross-head 12 and the spindle turning therein, the face-plate 10, traversed by the spindle and having slots 21, the tumbler 18, turning on the spindle and in bearings on the face-plate and having slots 20, pin 17 on the spindle, and springs 11 on the bolts, substantially as and for the purpose set forth.

4:. The combinatiomin a sash-lock, of the plate 3, secured to one sash and having the inclines 5 and bolt-holes 6, the face-plate 10, secured to the other sash and traversed by bolts 7, and a spindle 13, connected, as de scribed, to the cross-head 12, tumbler turning on the spindle and in bearings 19 on the faceplate, pin 17 on the spindle, the face-plate and tumbler being slotted at 2 1 and 20 for the passage of the pin, and springs 11 and 15, adapted to force the bolts and spindle inward, substantially as and for the purposes set forth.

5. The combination, in a sash-lock, of the plate 3, with inclines 5 and bolt-holes 6, the face-plate 10, the spring-bolts 7, the cross-head 12, with slot 21, the spindle 13, with head 22 and locking-spring 23, the spindle provided with a recess 24 and a pin 17, the tumbler having slot 20 and turning on the spindle and in bearings 19 on the face-plate, and springs 11 on the bolts, all constructed and adapted to operate substantially as set forth.
