IMPROVEMENT IN SASH-.FASTENERS Specification forming part of Letters Patent'No. 217,313. dated .Iuly 8, 1879; application filed May 2, 1879.
To all whom it may concern: Be it known that I, ANDREW A. ARM- STRONG, of Milford, in the county of Pike and same section as Fig. 2, but showing a modiv cation.
Fig. 4 is a detail horizontal section of the lock, taken through the line y y, Fig. 5. Fig. 5 is a detail cross-section of the same, taken through the line z z, Fig. 4. Fig. 6 is a detail front View of the modified forni of the catch-bar. Fig. 7 is a detail side view of the lower part of the catch-bar.
Similar letters of reference indicato corresponding parts.
The object of this invention is to furnish an improved sash -1ock for windows which shall be simple in construction and convenient and reliable in use, being so constructed that itcannot be unfastened from outside the window, whether the sash be locked when closed or when partly raised, and which -will prevent all rattling. f
The invention consists in a sash-lock formed of thc case, the pivoted latch, the spring, and the notched catch-bar, whether the said catchbar be made short or long, as' hereinafter fully described. l
Arepresents the casing, B the lower sash, and C the upper sash, of a window, about the construction of which parts there is nothing new. Y
To the middle part of the upper side of the meeting-rail of the lower sash, B, is secured a metallic case, D, in the cavity of which is placed a latch, E.
The latch E is pivotednear one end to the end part of the bottom plate of the case D, and its other end projects through a slot in the end of the said case D, and is provided with a knob or other handle for convenience in operating it.
The'middle part of the forward edge of the latch E projects so as to pass over the rear or inner part of a hole through the forward part of the case D and engage with the catch-bar F, that passes through the said hole.
The. forward part of the case E projects beyond the edge of the meeting-rail of the lower sash, B, so as to overlap the forward part of the upper side of the meeting-rail of the upper sash, C, and bring the hole through the said case D over the joint between thesaid meeting-rails, to allow the barF, attached to and let into the. forward sideV of the meeting-rail of the upper sash, to pass through the said hole.
When the sashes require to be lockedonly when closed, the catch-bar F may bc made short, and may be provided with a single crossnotch in its forward side to receive the latch E, as shown in Figs. 3, 5, and 6; but when the sashes are required to be locked when closed and when opened more or less, the bar F may be made long, and may have several cross-notches formed in its forward side to receive the said latch, so that the said sashes may be locked in any desired position. `In the latter case the upper end of the bar F is attached to the top bar of the upper sash, G, as shown in Figs. 1 and 2.
rlhe latch E is held forward to engage with the catch-bar F by a spring, G, one end of which is attached to the said latch, and its other end rests against the side of the case D, as shown in Fig. 4.
I am aware that spring-catches have been attached to the upper rails of both sashes, so as to engage notched bars extending the whole length of the window or the length of the upper sash only; and I am also aware that a spring-catch attached to the upper sash and adapted to enter holes in the lower sash is not new; but
What I claim, and desire to secure by Letters Patent, is
A sash-lock formed of 'the case D, notched to receive the bar F, the pivoted latch E, the spring G, and the notched catch-bar F, whether the said catch-bar F be made short or long, substantially as herein shown and described.
ANDREW ADAMS ARMSTRONG.
