SASH LOCK AND LIFTER.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application led August 10, 1914. Serial No. 856,065.

To all whom t may concern.'

Be it known that I, JOHN A. JOHNSON, a citizen of the United States, residing at Lockport, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Sash Locks and Lifters, of which the following is a specification.

My invention is a combination sash lock and lifter and has for its object to provide an improved device for the locking of a window sash in position and for unlocking the same by the same movement which raises or lowers the sash.

A further object of my invention is to provide a new and improved structure and combination of parts to eiiect the object set forth.

In the accompanying drawings, Figure l is an elevation, partly sectional, of a window sash and frame showing my invention in place. Fig. 2 is a vertical section on the line 2-2 of Fig. l. Fig. 3 is a sectional view showing the movable parts of my improved device in the position which they occupy when the sash is locked. Fig. 4 is a similar view with the sash unlocked. Fig. 5 is a plan view of the parts in the position of Fig. 3. Fig. 6 is a similar View of the parts in the position of Fig. Ll. Fig. 7 shows an alternative construction of the locking bolt.

In the embodiment of my invention illustrated herein, bolts l are held in a locked position by a locking lever 2 operating through reciprocating rods 3 and actuated by a spring 4; and are released from a locked position by means of a pivoted linger bar 5 acting through pins `6 and 7. The linger bar serves also as a catch or handle by which to raise and lower the sash. The reciprocating rods 3 and the bolts l are contained in a suitable bore in the Window sash, and when in a locked position the bolts engage cam sockets 8-set at intervals in the stile or amb of the window casing. A suitable plate 9 is attached to the sash at or near the middle and opposite the bore containing the rods 3 and is provided with lugs l0 perforated near their inner extremities for receiving the ends of the said rods. Upon a standard l1, mounted on the plate 9, is pivotally mounted the locking lever 2 which is actuated by the torsion spring 4 to rotate in the direction of the arrow shown plates 9 as soon in Fig. 3. Compression springs l2 are connected with the heads of bolts l and bear against the lugs l0 so as to exert a constant outward pressure on the bolts l.

he nger bar 5 is provided with stop shoulders 13 adapted to contact with the as the locking lever 2 has released the rods 3 and bolts l.

In operation, assuming that the sash is closed in the position shown in Fig. l (when the lever 2 and pins 6 and 7 will be in the position shown in Fig. 3), the finger bar 5 is lifted, the immediate effect being to depress the pin 6 and rotate the lever 2, thus releasing both rods 3. The upper stop shoulder 13 then comes in contact with the plates 9, preventing further pivoting of the finger bar, and continued upward pressure on the linger bar serves to raise the sash` the bolts l being free to slip out of engagement with the curved sockets 8. When the sash has been raised to the desired height, the finger bar 5 is released. The bolts l are then held in engagement with a pair of the sockets 8, by the action of the compression spring l2, and the inner ends of the rods 3 are flush with the inner sides of the lugs 10, and the action of the spring 4 causes the lever 2 to rotate in the direction indicated by the arrow in Fig. 3 until stopped by the pins 6 and when the ends of the lever are respectively opposed to the ends of the rods 3, thus locking the bolts securely in position.

hen it is desired to lower the sash. the iinger bar 5 is depressed, and the pin 7 opcrates to rotate the lever 2 with the same eiect of releasing the rods 3 and permitting the withdrawal of the bolts l. The lower shoulder 13 then comes in contact with the plates 9, and continued pressure on the iinger bar 5 brings the sash down to the desired position, when the linger bar is released and the locking action takes place as before.

In Figs. l, 2 and 5, I have shown the locking bolts as made with a smooth rounded end. In the alternative construction shown in Fig. 7, a roller 14 is substituted for this construction, the operation being as above described. Other modifications of the structure may be made without departing from the spirit and scope of the invention.

I claim as my invention:

l. In a sash lock and lifter, spring-actuated bolts, a spring-actuated pivoted locking v MM lever, and a linger bar adapted to release said bolts by rotating said locking lever.

2. In a sash lock and lifter; springactilated bolts on opposite sides of tliesasli` spring-actuated locking means normally operating to hold saidbolts in a locked position, and a finger bar pivoted to said sash and operatively coactingwith said locking means to withdraw the latter.

3. Inl a sash lock and lifter, in combination, bolts, a spring-actuated locking lever adapted to hold said bolts in a locked position, and a `piveted finger bar adapted to rotate said lever out of a looking position when said downward.

l. In a sash lock and lifter, in combination, spring-actuated bolts, a spring-actuated pivoted locking lever adapted to hold said.

bolts in a looked position, and a finger bar having arms coacting respectively ,with the arms of said locking lever for rotating said lever out ofa locking position when said linger bar islifted or depressed.

,5. Inl a sash lock and lifter, a pair of spring-actuated opposed reciprocating bolts having their proximate ends spaced apart;

a locking lever adapted to be interposed 1n a direct line between said proximate ends; and

Copies bf this patent may be obtained for finger bar is tilted upward or a finger bar pivoted to the sash for raising or lowering lie-sash andlsiifiiiltaililsly to rotate said looking lever to release said bolts.

6, In asash lock and lifter, a plurality of cam sockets; a pair of spring-actuated bolts adapted to engage with said sockets a single pivoted spring controlled locking eveiadapted to Iloelr s aidloolts in place; a pivoted linger bar adapted to raise or lower the sash; and two pins extending from, said fingerbar and bearing respectively onopposite sides of said locking' lever, whereby said leveris held to an operative position when the n'ger bar is at rest and Nis rotated to. release the boltswhen the finger bar is either raised or depressed.

7. In a sash look and lifter, a paird'of springactuated bolts; a singlev p ivojted spring-controlledl locking lever 4for looking said bolts in place; and apivoted linger bar for raisins 01 lowerln's the Sash. sadrba'r having arms coaoting with said locking lever to unlock the same. In testimonywhereof, 1 hereunto set my hand in the presence of two witnessesa,
