SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent N 0. 642,651, dated February 6, 1900. Application filed September 19, 1899. Serial No. 731,028. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANK E. WALTERS, a citizen of the United States,residing at Waterbury, in the county of New Haven and State of Connecticut, 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 to make and use the same.

My invention relates to that class of shutter-fasteners which are operated by means of a lever acting automatically in conjunction with a notched stud on the window-sill when closed and with a hook projecting from the building when open.

The objects of this invention are to secure an automatic shutter-fastener of the class above mentioned which may be manufactured more cheaply and at the same time provide greater security than those now in general use, which occupies the least possible space between the shutter and the window-sash, which operates easily, and which is not liable to get out of repair. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a portion of a window-sill and shutter, to which shutter is attached a fastener, also shown in perspective; Fig. 2, a side elevation of a retaining-hook; Fig. 3, a side elevation of a notched stud; Fig. 4., a front view of the fastener, together with a portion of a shutter and sill; Fig. 5, a ground plan of the fastener; Fig. 6, a section on the line w in Fig. 4.; Fig. 7, a front view of the fastener in modified form; Fig. 8, a ground plan of the fastener in said modified form, and Fig. 9 a front view of the fastener in a second modified form.

Similar letters refer to similar parts throughout the several views.

A is a plate which is secured to the shutter by the screws J and K through holes provided for that purpose and to which the operating-lever B is attached.

B is the lever, which is secured to the plate A by the rivet N and which engages the notch in the stud (shown by Fig. 3) when the shutter is closed and the hook (shown by Fig. 2) when the shutter is open.

D is a spring which is secured to the lever B by the rivet E.

F is a spring used in a modified form and is secured tothe lug H, which is bent from, riveted to, or cast upon the plate A.

I is a hole or slot cut through one of the an= gle planes of the recess formed in the plate A.

L is the lower part of a shutter, and M is a window-sill in which the notched stud (shown in Fig. 3) is driven.

N is the rivet by which the lever B is riv*- eted to the plate A.

The operation of the fastener is as follows: The angle-plate, recessed and pierced, as shown by the drawings, and having riveted to it the lever B, to which is secured the spring F, as shown by Fig. 7, is secured to the bot tom rail of the shutter, the shutter having been first mortised to admit the plate, so'that the front face of the plate is in the same plane as the inside face of the shutter. It will thus be seen that the fastener proper occupies no additional space. The notched stud (shown by Fig. 3) is driven into the window-sill, so that the long beveled side of its head engages the part a of the lever B as the shutter is closed. As the part a of the lever B commences to engage the beveled part of the head of the stud the lever is raised until the part a of the lever comes over the notch or slot 5, when the lever is forced into the said slot by the action of the spring or, when not used in combination with the spring, by its own weight. In like manner the lever operates in combination with the hook which projects from the building when the shutter is open. To release the lever from its secured position when either closed or open, the lever is raised by that portion thereof marked d. To secure the shutter in a closed position, the shutter is simply swung around to a closed position and the fastener acts automatically, asabove described. In like manner the shutteris secured in an open position by swinging the shutter to its proper position, the fastener likewise then acting automatically.

Of the advantages of this fastener over those now in general use it may be observed that the working parts of this device when attached to a shutter are concealed from view and exposure. I accomplish this by bending the plate'A in such a manner that a housing 6 is formed, two sides of which are practically at right angles to the face of the plate. The forward portion of the lever occupies this housing 6, the lever extending back through a slot or hole in the rearward side to said housing 6, so that the greater part thereof and the operating-spring are incased back of the plate A. There is no space between the shutter and the window required to operate this device, so that a screen may readily be placed between the window-sash and the sh u tter, while in the ordinary shutter-fastener so much of the space between the shutter and the window-sash is occupied by the fastener that it is impossible to place a screen between them. It will also be readily seen that by placing this device in the above-described position on the shutter to open the shutter from the outside is diflieult, the thumb-piece of the lever being out of reach, and that consisting of so few parts it is not likely to get out of repair.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A shutter-fastener comprising a faceplate which extends rearwardly to form a housing, the housing adapted to be mounted in a mortise of the shutter; and a latch pivoted to the rear surface of the plate and extending through a side wall of the housing, a downwardly-extending nosing and a handle formed on the latch and lying within the housing, the nosing of the latch being adapted to engage a keeper on the sill substantially as described.

2. A shutter-fastener comprising a faceplate which extends rearwardly to form a housing, the housing adapted to be mounted in a mortise of the shutter; a latch pivoted to the rear surface of the plate and extending through a side wall of the housing, a downwardly-exteu ding nosing and ahandle formed on the latch and lying within the housing, the nosing of the latch being adapted to engage a keeper on the sill; and a spring situated behind the rearsurface of the plate and arranged to exert a downward pressure upon the latch substantially as described.
