SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 459,292, dated September 8, 1891.

Application filed January 8, 1891. Serial No. 377,111. (No model.)

T0 all whom-it may concern.-

Be it known that I, EDWIN T. KEENER, of Moberly, in the county of Randolph and State of Missouri, have invented a new and useful Shutter-Fastener, of which the following is a full, clear, and exact description.

My invention relates to improvements in shutter-fasteners of the latch-hook type, and has for its objects to produce a simple, inexpensive, and practical device of the class indicated which will afford means to securely lock a pair of shutters in closed adjustment and release them from within the apartment without raising the sash. Y

To these ends myinvention consists in the construction and combination of parts, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.l

Figure l is a broken transverse section of a window-frame, the lower sash closed and one shutter with its fastener in cross-section indicating alocked condition,the improved shutter-fastener being represented in the initial stage of adjustment necessary7 for a subsequent release of the shutter. Fig. 2 is an enlarged view of the shutter-fastener in crosssection, a closed shutter broken, and the subsill of a window-frame, also broken, the parts of the fastening device being represented in a locked condition. Fig. 3 is an enlarged plan viewof the shutter-fasten er, the releasing-rod being shown broken and the shutter-hooks in Fig. 4 is an enlarged detached reversed plan view of the rocking latch-plate,

which is part of the improved device. Fig. 5

is a plan view of the base-plate and securingscrews therefor. Fig. 6 is a modified form for a locking and releasing device that is an important feature of the invention, embraced between the terminals of the line (i 6 in Fig. 3 and viewed in the direction of an adjacent arrow. Figs. 7 and 8 are plan and side views, respectively, of the device shown in Fig. 6; and Fig. 9 represents another modiiication for the device that operates the rocking latchplate.

In the drawings, A represents the sub-sill; B, the window-frame stile broken; C, the lower part of a lower sash, and D the lower portion of a shutter hinged to swing on the Windowframe.

The shutter-fastener mechanism is mainly contained in or supported on a casing that yconsists of a base-plate E and a cap-plate F,

said casing, when in position, being mounted upon and secured to the sub-sill A at a proper point to permit its internal latching device to be engaged removablywith two shutter-hooks, preferably, or one hook if a single shutter is to be secured. Y

The construction of the vfastener is as follows: The base-plate E is substantially rectangular on its edges, of a suitable length and width, and at each end has vertical ledges a formed on it of a proper height, each ledge being oppositely grooved on its top edge to receive the trunnion ends b of a rocking latchplate G, the baseplate having screw-holes provided at proper points to receive the screws c, whereby it is secured on the snb-sillA, one of the edges of the base-plate being notched, as at d, for the free movement of another part of the device, which will be explained in its order. The rocking latch-plate G is of such a length proportioned to that of the base-plate E between its ledges a that it will rock freely thereon when its trunnions h are seated in the grooves of the ledges a. On the upper face of the rocking latch-plate G ltwo hooks e of similar shape are formed at the edge, which is forward of the trunnions h and near the ends ofthe latchplate, so as to adapt said hooks for an engagement with the shutterhooks I, that are securedat proper points upon the shutters D and project therefrom rigidly, the cap-plate F having its face adjacent to the shutters cut away to afford freedoin for the insertion of the hooks I above the hooks on the plate G, as shown by dotted lines in Fig. 3. Near the longitudinal center of the rocking latch-plate G a depending limb f is formed thereon substantially at a right angle to the general surface of said plate on its lower side, which limb is preferably constructed as shown in Figs. 2 and et, the first figure indicating the si de and the latter named the bottom of the limb, which is notched at g for the engagement therewith of an end of a wire spring, which will be further explained. A notch 71.2 is cut' in the limb f opposite the notch g and above it, there being a dange- ICO wall h permitted to stand integral with the' body of said limb and a shorter projection formed on the limb, so as to afford a detentear 7L', the notch h2 separating the ear and flange-wall, as shown in Fig. 4. The rod J is made of such a proportionate length that it will extend from the inner face of the subsill A through a perforation made in said sill transversely and project within the incasement of the shutter-fastener, there being a lateral lip t' formed on its inserted end, either of solid metal or in loop form, which is of a proper thickness and breadth as well aslength to adapt it to rock within the case of the fastener and enter the notch h2 when the rod is longitudinally adjusted to effect such an engagement of parts, the body of the limb f having a perforation of proper size formed in it at a point which will allow the rod] to pass loosely through the limb and the latter named to vibrate without binding upon said rod. There is an aperture 7c cut in the vertical Wall of the cap-plate F oppositethe notch d in the base-plate E, through which the rod J is inserted, and upon said rod, adjacent to I the limbf of the latch-plate G, a washer is preferably located, whereon one end coil of a spiral spring m impinges, the other end coil of said spring being in contact with a collar m', that radially projects from the rod J at such a point as will permit the reciprocal movement of said rod and the proper vibration of the rocking latch-plate G. As represented in Figs. 2 and 4, the spring m has one terminal end n inter-locked with the notch g of the limb f, as before mentioned, this extended depending end portion being curved toward the limb, so as to adapt it to exert pressure upon the freelower extremity of the Same and when the parts are properly adj usted rock the plate G upwardly. Below the ear h on the limb f said limb is cut away to produce a shoulder on the advanced portion of the same, as shown in Fig. l, so that the partial rotation of the rod J in a proper direction orA away from the flange-Wall 7i, when released from the notch h2, will carry the edge of the lip t' below the ear h', as shown by dotted lines in Fig. 4, and thus adapt the latchplate G to rock on its trunnions b in a downward direction, so as to release the shutterhooks I Awhen the rod J is pulled by its thumb-knob p sufliciently to effect such a rocking movement of the plate G.

As shown in Figs. 2 and 5, the cap-plate F of the casing of the shutter fastener and contained parts is screwed fast by the screws r to the sub-sill A, and, if necessary, there may be a slight excavation made in the latter to facilitate the freedom of action of the parts, as represented in the figure named, ob long holes being made in the latch-plate G for the insertion of the screws r and free movement of said plate. In use the lip t' is turned by the rod J and knob p thereon so as to give it a Vertical position, the spring m causing the plate G to rock upwardly and engage the hooks I and simultaneously inter-v lock its notch h2 with the adjacent end of the lip,I as shown in Fig. 4. The engagement of parts just described will afford a support for the horizontally-extended portion of the latch-plate G, which, when hooked to the shutter-hooks I and thus braced, will retain the shutters closed and locked untilaproper manipulation of the rod J is effected to release them.

In Figs. 6, 7, and 8 a slightly-modified form of the locking device for the rocking latchplate G is shown, which consists in the cutting away of the flange-Wall h, so as to produce two similar detent-ears h. The rod J is also provided with two lips i', extended oppositely, the lower portion of the depending limbf being formed to permit a half-revolution of the rod J and said lips, so that the rod may be moved to the right or left when pushed in so as to release the engaged hp from the notch between the ears h the horizontal adjustment of the lips permitting the latch-plate G to rock on its trunnions and release the shutter-hooks I, as before explained.

In Fig. 9 there is another modification of the device shown, which consists in providing the cap-plate F with a chambered projection F', that is so located as to afford a receiv ing-case for the spring fm, which spring has one end in contact with the inner surface of the end wall of the spring-case, the other terminal end bearing upon the limbf, which latter is perforated to receive the rod J and its head o. In use-an inward draft upon the rod J, effected by pulling the knob p,.(shownfin Fig. 1,) will rock the plate G downward and release the hook I, the release of the rod permitting the spring m to restore the latch-plate IDO Gto its normal position, as represented in Fig. 9.

Having thus described my invention, I

claim as new and desire to secure by Letters Patentl.
