Specification of Letters Patent.
' Patented Sept. 19, 191
I Application filed ane 10, 1916. a Serial No. 102,835..
To all whom it may concern:
Be it known that 1, JOHN J. MoCoRMAoK, a citizenof the United States,'residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Window-Latches, of which the following is a full, clear, and exact specification.
This invention relates to sash locks for fastening together the meeting rails of upper and lower window sashes, and has for its object to provide an automatic lock of improved construction which may be so arranged as to automatically lock when the meeting rails are brought together, or so adjusted as to permit the meetingirails to come together without looking the sashes together.
Another object is to provide improved means for automatically lockingthe sashes together when brought into horizontal aline- Y ment, and especially to improve the-,means for releasing the locking bolt at the proper time. v j
Other objects will appear as the description proceeds. r Y
Theinvention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.
In the accompanying drawings, wherein similar reference characters designate corresponding parts throughout the several views: Figure 1 is a vertical section through the lock mounted on the meeting rails of window sashes, showing the bolt retracted and in position to be released when the meeting rails are brought into horizontal alinement. Fig. 2 is a similar view showing the meeting rails in horizontal alinement and the bolt in looking position. Fig. 3 is a detailed perspective view of the bolt carrying member of the lock, and Fig. 4 is a similar view of the keeper.
Referring more particularly to the drawings, 1 and 2 designate the meeting rails of the upper and lower sashes, respectively. The bolt carrying member 3 of the lock is suitably fastened to the meeting rail 2 of the lower sash, and the bolt 4 extends through a chambered portion 7 of said member and is normally arranged in a substantially horizontal position. The rear end of the bolt 4 projects from the member 3 and is formed with a. handle or knob 5'. The other end or the bolt is rounded or beveled, as at 6 and projects through an opening 12 in an upright bracket 13 rigidly fastened to the member 3 and arranged substantially in line with the meeting edges of the rails 1 and 2.
WVithin the chamber 7 of the member 3, a spring 9 is coiled about the bolt 4 and presses against a pin 8 carried by the bolt for normally holding said bolt in looking position. The inner end of the bolt has vertically alined notches 10 and ll formed in its upper and loweriaces, respectively, for engagement with the upper and lower edges of the, opening .12 in the upright bracket 13 when the bolt is retracted lhe other end portion of the bolt is provided with similar notches l4; and 15 for-engaging the upper and lower edges of an opening 16 in the chambered portion of the member 3 when the notches 10 or 11 are engaged with the edgesv of the opening .12. As illustrated a in Fig. 1, when the bolt is retracted, :the
handle 5 may be depressed vfor engaging the notch 10 with the upper edge of the opening 12 and the notch 15 with the lower edge of the opening 16, or the handle may be raised for engaging the notch 11 with the lower edge of the opening 12 and the notch 14 with the upper edge of the opening 16.
In either of these positions, the bolt will be held retracted, but when theinner end of the bolt is raised and the outer or handle carrying end thereof 'is lowered, as shown in solid lines in Fig. 1, said bolt is in position to be automatically released when the meeting rails of the two sashes are brought into horizontal alinement, while the bolt when arranged as shown in dotted lines in Fig. 1 will remain in retracted position when the meeting rails are brought together. It will be found very convenient to arrange the bolt in the latter position when the sashes are to be frequently raised or lowered.
The upper end of the bracket 13 is made flat, as at 17 or otherwise formed as a stop for engaging the top of the window frame when the lower sash is fully raised.
Said bracket 13 is provided with an opening 18 above the opening 12 therein, and in said opening 18 a bolt releasing lever 19 is pivoted at 20. The outer end of said lever is bent downward, as at 21 to engage the upper face of the bolt, while the inner end of said lever is provided with a T-shaped head pun 22 projecting beyond the bracket and into the path of oppositely arranged grooves or ways 26 in the upright portion-'24; of the keeper 23 which is secured to the meeting rail 1 of the upper sash. The groovesor ways 26 terminate at the bottom in shoulders 27, while the upper ends of said grooves are open to receive the T-shaped head 22 of the lever 19 when the meeting rails are brought together, as illustrated'in Fig. 1. hen the meeting rails are moved fully into horizontal alinement, the extremities of the oppositely extending portions of the T shaped head 22 of the lever 19-Will engage the shoulders '27 at the bases of the grooves 26 and cause the downwardly turnedend 21 of said lever to press against the upper face of the bolt 4: and release the notch 10 from the upper edge of the opening 12 and the notchlofrom the lower edge of the opening 16 thus permitting the spring 9 to shoot the bolt into an opening 28 in the keeper, as shown in Fig. 2. The central portion of the upper end of the keeper is preferably rounded or beveled, as at 25, to permit the beveled end 6 of the bolt to more easily ridedown to the locking opening 28. As illustrated, the upright portion of the bracket 13 may project slightly beyond the meeting rail 2 of the lower sash, and the base portion ofthe keeper 28 be provided with'a notch 29 to provide clearance for the bottom of this projecting upright portion of the bracket.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
-1. In a sash lock, the combination with a spring pressed bolt-having a notch adapted to engage a fixture when the bolt is retracted for retaining the same in that position, of
a keeper having a shoulder, and a lever having a projection to engage said shoulder when the meeting rails are brought together for automatically releasing the bolt.
' In a sash lock, the combination with a spring pressed bolt having notches in its upper and lower faces adapted to engagea fixture for retaining the bolt in retracted different parts of a ,fixture for retaining the bolt in retracted position, of a keeper having ashoulder, and a lever intermediately pivoted andshaving one end extending into the path of the shoulder onthe keeper and its other end adaptedtoengage the upper face ofzthe bolt for automatically releasing said .bolt when; its upper notch is engagedwith the fixture andthe meeting rails are. brought together, the lever being out of range of the ,bolt whenits lowerj notch-is engaged with thefixture.
.4. In acsashlock, the combination with a spring pressed bolt having a notch .to engage a fixture for holding said bolt in retracted position, of a keeper having oppositely ar- -range d shoulders, and' a lever 'having a T- shaped head to engage said shouldersfor revleasing the bolt when the meeting rails are r brought together.
.In testimony whereof I have signed my nameto this specification.
JOHN J. MOCORMAOK.
