SPEUIFIGATION forming part of Letters Patent'No. 701,966,` datedJ' une 1Q, 1902.
Application filed Tilly 12, 1901.
To all whom t may concern,.- u
Be it known that I, JAMEsH. THORNTON, a citizen of the United States,residingat-Evans ton, inthe county ofCook and State of Illinois, have invented certain new and useful Improvements in Sash-Locks; and I do dee clare the following to be a' full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which itpap pertains to make and use the samefreference being had to the accompanying drawings,and to the gures of referencemarked thereon,A` which form a part of thisvispecification.d I
This invention relatesto an improvement;` in sash-locks. Its object is to provide an improvedjsash-lock which will automatically lock the sashes of a window whenthey are c closed.
. cated at 6.
l p andthe upper rail thereof at 10.
A further object is to provide an improved sash-lock by which thesashes may be locked when partly open. p N
e The invention is hereinafter described, and is illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a window, partly .broken away, showing` my invention applied thereto. Fig. 2 is a vertical section ofthe. same. Fig. 3 is a longitudinal or verticall section of the lock detached, on a larger scale. Fig. 4 is a cross-section on the line 4 4 of Fig. 3. l
Referring more particularly to the drawings, the side of the Window-frame is indi- The stile of; the upper sash is indicated at 7 and the lowerrail thereof at 8. The stile of the lower s"ash is indicated ata` A vertical mortise inthe stile 7 of 'the upper sash contains the lockproper', comprising a casing 11, seated in the mortise and secured to thev stile vby screws 11?, theqouter face 11a of the casing being iu'sh with the face of the stile, and a tumbler or latch 12, which is pivoted to the casing by a pin 13.. The latch extends vertically and ispivoted to swing for- -wardly or outwardly beyond the face of the casing. Behind the latchwithin the casiugis a iiat spring 14, held between the latch and the Y casing, which spring acts to normally throw the latch out. The latch is adapted to be retained within the casing to avoid engagement with the lower sash by means of the verticallylocked.
Serial No. 68,030. (No models extending yieldingbolt-15,1the head ofI which is adapted to enter the socket 16 in thelower v end of the latch when it is pressed back into the casing. The'spiral spring17iswound around the vboltand is retained thereon be-` tween the pin 18 andthe'bottom ot'. the cas' push-'pin 19eXtending without the'casing, is
adapted to force the bolt out-of engagementwith the latch; The inner end of the pushi pin is bifurcated, as at 20, and thebifurcated portions are beveled on their lower1 sides or edges, as shown at 2l. The bolt 15 is cut away on each side, so as to pass between the spring 23is secured Within thecasing andl engages in a notch 24 in the push-pin, acting to normally force thepin outward. Upon the top rail of the lower sash'fis mounted'a block 25, faced lby a metal plate 25a to resist wear, and this block is adaptedto -be engaged by the latch when the sashes are To the outer face'of the stile 9 of the lower s ash is secured a beveledv rib ,26, which is adapted to slidinglycontact'with the pushi pin 1.9 whenever the lower sash is raised or the upper sash lowered. The action of this rib is to force thepin- 19 inwardlyand to release the latch. The rail Shas a vertical recess orgroove 8L to allow the passagel of the rib'26, and the rail lOha'sa groove 10a, to allowthe passage ofthe pin 19`^during the relative movements of the sashes.`
In operation whenth'ef'sashes are closed'the parts are in -the position .shown .in Fig. 2. When the lower sash is to be raised, the catch 12 is pressed in by hand untilit is flush with the face of the casing, when it will beengaged Vand retained by the headoff the bolt" 15,l as .shown in Fig. 3; This permits the sashes to be moved, when vthe rib126will comeiin con- Abifurcated portions of4 the push-pin, as shown ginjFig. 4, whereby shoulders 22' are formed,4 which bear against the bevel of the push-pin,
tact with the pin1'9 and force the same in,
causing the bolt 15 to be released from the latch and permitting the latter to be sprung outwardly into sliding contact with the outer face of the stile of the lower sash, in which position it remains until the sashes are closed, when it swings outwardly above the head of the block 25, thereby ellectually locking the sashes. It will be seen that whenever the window is opened the latch is automatically released and is in position to engage the lower sash whenever the sashes are closed again, the result being that whenever the sashes are closed they are locked and known to be locked by the fact of being,r closed. Vhen it is desired to lock the sashes in a partly-open position, as to lower the upper sash for ventilation, the latchis pushed in slightly, enough to avoid the block 25, but not enough to allow the bolt l5 to enter the socket 16, and so retained by the finger until lthe lower end of the latch passes below the plate 25. The latch will then engage the top of the rail in the recess 25", formed in the inner face of the block for that purpose.
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
In a sash-lock, in combination with a window frame and sashes, a casing in the upper sash, alocking-latch pivoted therein, a spring to project the latch to engage the lower sash, a yielding bolt to engage the latch and retain the same When retracted,a push-pin to actuate the bolt to release the latch, and a rib on the stile of the lower sash adapted to strike and pass the push-pin in either direction when either sash is moved and thereby disengage the bolt and release the latch.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES H. THORNTON.
