SASH-FASTENER.
SPECIFICATION forming part ofLetters Patent No. 277,591, dated May 15, 1883.
i Application tiledDecenl)er1S,1S8 2. (Nonodel.)
To all whom it may concern:
Be it known that I, WILLIAM LAw'soN Mc- KELVEY, a citizen of' the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented new and useful Irnprovements in Sash-Locks, of which the following is a specificat'ron.
The style of sash-fastener which I have improved is adapted to lock both the upper and the lower sash of a window together and to the casing at the same tirne in any desired position by a locking device secured upon the top of the upper bar of the lower sash, having two bolts arranged at right angles to each other and operated together, so, as to engage both the upper sash and the window-casing, and to be unbolted therefrom.
The specific natter ofimprovenent consists ofa combination of devices, and in details ot' construction hereinalter described, and cmbraced in the clairns.
Referring to the acconpanying drawings, Figure l represents a horizontal section of the window-sash taken above the meetingrail, showing both sashes locked together and to the window-casin g; Fig. 2, a similar view, the top plate of the locking device being removed to show the bolts locked by a turning cranked stem; Fig. 3, a similar view, showing the bolts unlocked; Fig. 4, a cross-section taken through the cranked stem, by which the bolts are locked when engaged with the sash and the window-casing; Fig. 5, a side view of the lock, and Fig. 6 the tubular notched key.
As stated, the bolts are arranged at right angles to "each other, and the case for containing them is suited to such arrangement. It is carved out at the end next the window-frame, so as to clear the parting-strip of the windowcasing and the sash-cord. It is screwed to the top rail of the lower sash, so that one of its bolts, a, will enter a corresponding hole in the window-casing, and the other bolt, b, will enter a'hole in the uppe'r sash, the said boltspro- 45 jectingthrough holes in their confiniug-case and maintained in position therein by suitable guide-strips, cc', cast with the case. The bolt a, which locks with the window-casing, is forked or divided at its inner end, one branch, a', sliding within the notched guide-strip c, and the other, az, serving to receive the action of a locking cranked stern, d, secured in suitable bearings, c, in the case, and adapted to be turned by a key to abut against the end ot' the bolt-branch, e2, to lock it, as will be more fully presently7 stated. The bolts are corinected by abell-crank lever pivoted to astud,f,, in the case, its longorhandle end,g,extending through a slot, h, in the front side of the case, and connected by a notch, s, to the bolt a, and having its inner or short end connected by a notch, 82, to the bolt b, by which both bolts can be projected and withdrawn simultareously. The slot h islong enough to allow the bolts to have the proper throw in the movernents of the lever. The bolt a has a projection, i, on the side next the lock-case, and a 'plate-spring, o, is arranged to bear against the side of the bolt to receive the action ofits side projection, i, in such rnanner as to hold the bolts within the case when withdrawn, and thus keep tlem free of the sash and the casing in raising and lowering the windows. The bolt projection 'fi rides over the bearing part of the spring, and the pressure of the latter against the bolt holds it firrn in being moved ir and out, and prevents rattling of the bolt parts. The locking cranked stern (Z is secured in a bearing, c, across the bottom ofthe case, behind the inner end of the bolt n., and eX- tends into or through an opening, m, in the front side ofthe case, which opening is made larger than the stern, so thata tubular key, u,can be inserted through said opening over 'the end d of the stern to operate it. The bearing and the free ends of the stern are cylindrical, and the crank part d is flat, and it can he turned over through halfa circle on the inner side ofthe guide-strip cto allow the boltato be withdrawn within the case; or the crank part can be turned over against the inner end of' the bolt to lock the bolts, so that they cannotbe withdrawn by the bell-crank lever. The key u has a notch, rr, in the side of its tu bular end adapted to fit over lthe crank part d of the stern, and for this purpose a key rnust be inserted through an opening in the guide-strip c, so
that the locking-crank part cannot be reached` except by a tubular notched key passed through the outer and inneropenings through which the stern part d' of the crank passes, and then overthe flat crank part d ofthe stem.
- side projection, i, the bolt b, having the notch 82, the bell-crank lever connecting with the The key is only used when it is desired to lock and to unlock the bolts. The bolt a locks both sashes to the window-casing, and the bolt blocks both sashes together. The window-casing and the npper sash have holes corresponding with the respective bolts, and they are so placed that the lower sash may be raised to any desired position and be locked to the casing and the upper sash; or the upper sash may be lowered to any desired point and secured; or the lower sash may be raised and the upper sasl lowered, and both locked at any desired point, so that both sashes may be left in open locked position day or night. The sashes may be hung by weights in the usual manner.
I claim- 1. The sash-lock lerein described, consisting of the bolt a, having the notcl s, and the notches of the bolts, and the plate-spring n, arranged to bear against the bolt projection,
the several parts constructed and 'arranged as shown and described. X*
2. The combination of the bolts a b, the bell-crank lever conneetin g them, as described, and the lock-case with the cranked stem d, adapted to be turned by a key over in position to lock the bolts when engaged with the sash and the window-casing, and to release such lock, substantial] y as described.
3. The turning cranked stem d, having the stem part d' cylindrical, the lock-case having the opening m, and the guide-strip c, combined with the bolt a, having the divided inner end, the bolt b, and the bell-crank lever, substantially as shown and described.
In testimony Whereof I have hereunto set my hand in the vpresence of two subscribing witnesses.
