Specification of Letters Patent. Application filed December 17, 1908. Serial No.
Patented Nov. 9, i 1909. 467,969.
To all whom 'it may concern:
Be it known that I, JOHN C. DEGGIM, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification.
My invention relates to sash-locks, and the invention consists in a sash-lock constructed and adapted to operate substantially as shown and described and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a cross section of the meeting portion of two sashes with my improved sash-lock fixed upon the front sash and in engagement with the rear sash. Fig. 2 is a plan view of the lock itself, and Fig. 3 is a rear elevation thereof. Fig. 4 is a perspective View of the latch and its screw. Fig. 5 is a perspective view of the case of the lock and Fig. 6 is a perspective view of the locking member.
2 and 3 represent the respective front and rear meeting rails of the inner and outer sashes 4 and 5, respectively, and my improved lock is adapted to be placed upon the inner meeting rail 2 and to engage the outer sash frame directly or indirectly at the side thereof and preferably at intervals so that the sashes may be set to open the window more or less by raising the lower sash or lowering the upper or outer sash as may be preferred, the distance which either sash can be opened to be determined by the point of engagement by the look, as hereinafter described. The said lock is constructed of three leading parts, the casing 6, the lock proper or member 7 and the latch. The casing is flat with a hollow interior and has front and rear openings 8 and 9 respectively to receive the locking member 7 in a more or less pivoted or tilting working relation. Thus, the said member is somewhat peculiarly fashioned so as to adapt it to my manner of use, the same being constructed with a straight flat body portion 10 having a central hole 11 and adapted to lie inside against the bottom of the casing between the openings 8 and 9. The front end 12 of said member is bent upward at right angles and extends through opening 9 and has its immediate extremity 13 bent forward at right angles, which brings said extremity in a line parallel with said body but at a higher elevation, while the opposite end 14 projects through the opening 8 in the rear ber from full angle of the casing at an inclination at something less than forty five degrees and is adapted to engage with one or the other of the stops 15 on the rear sash. One or more of such stops may be used and they may be spaced apart as preferred. In this case I show two such stops formed on the same plate or strip of metal, and the said stops have more or less angular shoulders against which the lock 14 abuts and in which position it can be locked by the latch 16. The sashes are locked in respect to each other when this relation of the parts is sustained. That is, when the bolt engages the stop 15 and the latch is swung in beneath the lip or extremity 13 as in Fig. 1, the upper sash cannot be lowered nor the lower sash raised. The said outer locking portion 14 of the locking member has shoulders 18 at each side at its base adapted to rest upon the casing at the edges of openings 8 and form a brace thereon. In fact this makes a support of such strength that the lock cannot be overcome by any pressure less than is required to crush the sashes or break the looking parts, and picking is impossible. Nevertheless the said bolt is pivotally maintained on these shoulders within certain limits, by a headed stem 20 which is threaded at its extremity and screwed into the hole 11 in said member and has a) spiral spring 21 wound about the same and resting in the boss 22 on the casing, the said pin having its head high enough above the boss to afford a pivotal'swing or tilt of said locking memto dotted lines, Fig. 1.
The spring 21 is strong enough to hold the bolt up normally as seen in Fig. l which also is the normal position of the parts, and the dotted lines in said figure show the depressed position of the bolt, as when the sashes are changed to higher or lower positions relatively, in which case the front end is depressed and the brace 14 is swung forward out of the path of the stop 15. This adjustment of the locking member is made particularly when the front sash is raised or the rear one lowered, but when the front sash is lowered or the rear one raised the said member will automatically accommodate itself to such movement by sliding over any one of the stops 15. However, being locked, whether the sashes be open or closed, the locking member will hold its locking position at all times until changed by hand even if latch 16 be not inserted.
The latch 16 is hinged to swing horizontally from dotted lines, Fig. 2, to full lines in said figure, to Figs. 1 and 3, and when the latch is in this position the bolt is positively locked and cannot yield for any purpose. The screw 23 upon which the latch is mounted may be one of the screws which fastens the casing in position, provided it be long enough.
What I claim is 1. A sash-lock having a hollow casing adapted to be fixed on the top of the lower sash and provided with openings front and rear in its top, a locking member having a straight middle portion at its center confined in said easing and upturned ends projecting through said openings respectively, one of said ends being outwardly inclined and adapted to make locking engagement with the upper sash and the other end having a right angled extremity overhanging a portion of said casing, a headed stem sus pending said locking member in the sash and a spring about said stem resting on said casing.
2. A sashlock having a casing with front and rear openings in its top, a tilting locking member having ends extending through said openings and a pivot spring support engaging the middle of said member and adapted to hold the same against the inside of said casing, said spring being outside the casing.
3. A sash-lock having a casing with open ings front and rear in its top, a locking member having a spring supported pivot suspending the same in said casing and its ends extending through said openings and adapted to tilt within limits on its pivot, said spring adapted to lift said member in the casing and a locking member adapted to be interposed between the front end of said locking member and the top of said casing.
In testimony whereof I aflix my signature in presence of two witnesses.
JOHN C. DE iGlM.
