FASTENING FOR MEETING-RAILS OF SASHES.
' SPECIPECATION forming part of Letters Patent No. 319,887, dated June 9,1885,
(No model.)
To all whom it may concern:
Be it known that I, J OTHAM S. ORUMP, a citizen of the United States, residing at W'estfield, in Chautauqua county, and State of New York, have invented a certain new and useful Improved Sash-Lock, of which the following is a specification.
My invention provides a unique, simple, and inexpensive lock for the meeting-rails of window-sashes, which is absolutely proof against being opened from the outside of the window, and which requires the use of a special key or equivalent tool to open it from the inside; The moving parts, except this key, are entirely concealed within an inclosing case or shell.
Figure 1 of the accompanying drawings is a transverse section of the meeting-rails of a window provided with my lock, the section cutting the look through its center. Fig. 2 is a plan of the lock detached. Fig. 3 is an inverted plan thereof with its bottom plate removed and turned back. Fig. 4 is a section out along the line 4 4 in Fig. 3, looking in the direction of the arrow. Fig. 5 shows the bolt removed in edge view and plan, and Fig. 6 shows the key.
Let A designate the case of the lock, to be screwed to the meeting-rail of the lower sash, and B the keeper or boX,to be screwed to the rail of the upper sash. The case Ahas a bottom plate, a, fastened on it, and in the top and bottom plates are formed corresponding holes, which receive the journals 1) and c of a disk-bolt,O. (ShownbestinFig. 5.) Oneside of this bolt is cut off segmentally, so that when the bolt is turned to unlock the window this side is flush with the front side of the caseA, as shown in Fig. 3. To look the window, the bolt is turned,as shown in Fig. 2, and fills and closes the aperture in the face of the case, when its portion projecting beyond the case A takes under the keeper B, as shown in Fig. 1. In the construction shown the bolt 0 has a concentric groove, d, Fig. 5, (shown in section in Fig. 1,) and on the under side of the keeper B is a corresponding rib, e, Fig. 2, also shown in section in Fig. 1. XVhen the boltis turned, this groove and rib interlock and hold the sashes tightly together. This construction, however, is not essential. The bolt is turned by means of a key, D, (shown in Fig. 6,) having a shank, f, which enters a central hole or recess, 9, in the bolt, and ears h h,
which engagewith notches t i in the journal I). By inserting this key and turning the bolt the sashes may be either locked or unlocked, and by removing the key the lock cannot be operated without great difficulty. Thus, by hanging this key in some convenient place not readily visible, and known only to the occupants of the house, an intruder in the house wishing to escape through the window will be baffled in his efforts to open thelatter and his escape will be prevented or delayed, thus in many cases aiding in his detection or capture. The key, instead of projecting into the bolt,
may be made with a tubular shank fitting over a projecting arbor on the bolt, which it may engage by any interlocking parts. On the under side of the bolt are formedtwo diametrically-opposite notches, j j, (shown best in Figs. 3 and 4,) and to the plate a is fastened a stifi leaf-spring, k, the free end of which engages the notches, as shown in Fig. 4, and
serves as a pawl .to prevent the bolt being turned backward. Thusthe bolt may always be turned around to the right, and when the proper position is reached the spring will snap into the notch, and by bearing against the inclined side thereof will slightly resist the further turning of the bolt. This spring always generates sufficient friction against the bolt to prevent the latter being turned accidentally. One notch j will suffice,if it be the one designed to hold the bolt when unlocked. WVhen the sashes are locked and the key removed,no operative part of the lock is visible, except the journal I), and to turn the bolt without the key would require the use of a screwdriver or other similar tool. The bolt cannot possibly be turned from the outside by inserting a blade through the joint between the meeting-rails.
I am aware that mutilated disk-bolts have before been used in sash-locks; but invariably the mutilated disk has been made as the hub of a radial lever, which turns from side to side back and forth to lock or unlock the sashes.
I am also aware that piano-locks have been made with a segmentally-mutilated disk-bolt turned by a key, and having flanges engaging the keeper, after the manner of an oscillating hook, to resist the lifting of the piano-lid. These hook-bolts act in a direction at right angles to the bolt in my sash-fastener, are capable of executing only a slight oscillation back and forth, and when unlocked are incapable of wholly filling the aperture in the face of the case through which they work.
I claim as my invention- 1. The combination of an inclosing-case, a disk-bolt mounted rotatively in hearings in said case and cut away segmentally on one side flush with the face of the case when the bolt is in its unlocked position, a leaf-spring fixed within said case and arranged to press against said bolt and frictionally retard its movement, and a notch in said bolt arranged JOTHAM s. GRUMP.
