SPECIFICATION forming part of Letters Patent No. 550,623, dated December 3, 1895. Application filed June 3, 1895. Serial No. 551,546. (N0 model.)

To LZZ whom it may concern:

Be it known that l, FRANK KRUPP, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Shutter-Fasteners and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in that class of shutter-fasteners which comprise a rod extending through the sill of a windowcasing and having a head at its outer end adapted to engage a keeper in the outer inember vof a pair of shutters or blinds; and its novelty and advantages will be fully understood from the following description and claim, when taken in conjunction with the accompanying drawings, in which- Figure 1 is a vertical section illustrating a portion of a window-casing and a shutter 0r blind equipped with my improvements. Fig. 2 is a section taken in the plane indicated by the line a: a; of Fig. l;Y Fig. 3 comprises detail perspective views of several parts hereinafter referred to.

Referring by numerals to the drawings, 1 indicates the sill, 2 the sub-sill, 3 the stool, and 4: the apron, of awindow-casing, all of which may be of the ordinary form and construction.

5 indicates a shutter or blind which has its free vertical edge rabbeted, as shown in Fig. 2, to form a portion 6, designed to rest in the rabbet 7 of its fellow shutter 8 when the shutters are closed, so that the shutterS cannot be swung open until after the shutter 5 is opened.

9 indicates a recess which is formed in the inner side of shutter 5, preferably at a point adjacent to the free vertical edge of the same.

10 indicates a countersink-plate which is secured by screws or the like in the shutter 5 over the recess 9, and is provided with an elongated slot 11 for a purpose presently described, and 12 indicates a passage which is bored or otherwise formed in the sill 1, subsill 2, and apron 3 of the window-casing and extends from the inner side of said apron to the outer edge of the sub-sill, as shown. The said passage 12 'is preferably pitched downwardly and inwardly, as shown in Fig. 1, so

as to bring its inner end below the stool 3, and it has the said inner end closed by an escutcheon 13, which preferably comprises two sections having their contiguous ends recessed, as indicated by 14, to form a square or round opening for a purpose presently pointed out, while its outer end is closed by the casting 15, having the vertical slot 16 and also having the recess 17 in its outer side, and the plate 18, which is countersunk in the outer edge of the sub-sill 2, and secured thereto, so as to rest in the recess 17 of the casing 15, and is provided with an elongated slot 19, which extends at right angles to that of the casting 15.

20 indicates the locking-bolt of my improved lock, which is preferably of a circular form in cross-section, and is provided at its inner end with a head 21, forming a convenient iinger-piece," through the medium of which it may be turned, and is also provided at its outer end with a T-head 22, which is preferably beveled, as shown, so as to facilitate its passage through the slot 11 of the shutter-plate 10.

` The heads 21 22 of the bolt 20 may be, and preferably are, formed integral with the body thereof, and for this reason and to avoid the necessity of forming a slot sufliciently large to permitthe passage of the head 22 the escutcheon is formed in two sections, as before described, with the small central opening which forms a tight-iitting bearing for the bolt and prevents lateral movement thereof. The casting 15 of the plate 18 at the outer end of the passage 12, is provided with slots 16 and 19 larger than the bolt-head 22, so as to permit of the said head being formed integral with the body of the bolt; but the disposition of the said slots at right angles to each other prevents lateral motion of the bolt--that is to say, the walls of the slot 16 in casting 15 prevent lateral motion of the boltbodyin the slot 19 of plate 18, while the walls of said slot 19 prevent lateral motion of the bolt-body vin the slot 16 of said casting 15.

In assembling the parts of the device the bolt 20 is first passed through the passage 12, after which the casting 15`is slipped over the head 22 of the bolt and adjusted to the position shown in Figs. 1 and 2. The plate 19 is then placed in the recess in the outer edge IOO of the sub-sill 2 and in the recess 17 of casting 15, after which the escutcheon 13 is secured to the apron in the manner described, so as to form a bearing for the bolt and limit the outward adjustment of the same.

In using the devicea person may with one hand rst shut the shutter 8 and then the shutter 5 and with the other hand first turn the bolt 20, so as to enable the head 22 to pass through the slot 11 of the shutter-plate, and then turn said bolt to the position shown in Fig. 1, so as to secure it in the shutter-recess 9, and consequently securely lock the shutters in their closed position. To unlock the shutters it is simply necessary to turn the bolt so as to bring its head 22 in alignment with the slot 11 in plate 10 and then draw said head through the plate 1l, when the shutters may be pushed open in the usual manner. Vhen the bolt-head 22 has been disengaged from the shutter, it may be drawn into the slot 19 of the plate 1S, which it iits snugly, and in this position it will exclude moisture from the interior of the passage 12, and will in consequence prevent corrosion of the parts of my improvements and rotting of the wood forming the window-casing. Vhen the bolthead 22 is drawn into the slot 19 of plate 18, the downward and inward pitch of the passage 12 and bolt 2O will prevent said head from casually workin g out of said slot 19 and interfering` with the closing of the shutters.

It will be readily appreciated that while cheap and simple and easy of application my improvements form a very strong and secure lock, and it will also be appreciated that such lock may be used to advantage in conjunction with those shutt-ers which are opened and closed through the medium of devices in a room without the necessity of raising the window.

Having described my invention, what I claim is- In the shutter fastener described, the combination of a window casin g havin g a passage extending through it, the bearing plate closing the inner end of said passage, the casting 15,r arranged in said passage adgacent to its outer end and having the elongated slot 16, and also having the recess 17, in its outer side, the plate 18, arranged in the sash and in the recess 17, of casting 15, and having the elongated slot 19, disposed at right angles to the slot 16, of casting 15, screws connecting said plate 18, and the sash, the endwise adjustable locking bolt having the body portion 1' arranged in the bearing plate and in the slots 1of casting 15, and plate 1S, and having the integral handle or head 21, at its inner end l and the integral T-head 22, at its outer end and a shutter having arecess in its inner side and a slotted plate covering said recess; said plate being designed to be engaged by the head 22 of the locking bolt, all as and for the purpose set forth.

In testimony whereof l affix my signature in presence of two witnesses.
