SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 485,799, dated September 2, 1890.

Application tiled May 14, 1890. Serial No. 351,763. (No model.)

To all whom, it may concern:

Be it known that we, RlcHEARD CONNER and ROBERT WALLBILLICH, of New Orleans, in the parish ot' Orleans and State of Louisiana, have invented a new and improved Shutter- Fastener, of which the following is a full, clear, and exact description.

Our invention relates to improvements in shutter-fastening devices; and the object of our invention is to provide means whereby the various shutters on a building may be simultaneously locked or unlocked.

To this end our invention consists in certain features of construction and combinations of parts, which will be hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a broken inside elevation of a building provided with the usual shutters and with the locking mechanism embodying our invention, the shutters ci one window bcing partially open and the shutters of the other window being locked; and Fig. 2 is a horizontal section on the line cc .x of Fig. l.

The building A is provided with shutters B,which are of the usual construction and are hinged to the frames H of the Windows C.

The windows are provided with cross-bars D, of the usual construction, having a central perforation d therein, and the shutters interlock in the usual manner, and one of them is provided with an imvardly-extending staple l), which projects through the perforation d ot' the cross-bar when the shutters are closed. The shutters are provided on the outside with suitable rings l', by which they may be opened, if desired. A pin e projects through the staple l) when the shutters are closed, and thus prevents the withdrawal of the staple and holds the shutters in a locked position. The pin e is fixed to the end of a bolt c,which is held upon the inside ot the cross-bar D in a horizontal position by the keepers e2 and is longitudinally movable in said keepers. 'lhe bolt c is curved inwardly at one end and is attached to a chain f, which extends over a pulley f adjacent to the window-frame H,

and which has at its lower end a weight f2. It will thus be seen that the weightf2 will hold the pin e from engagement with the staple b, thus permitting the shutters to be freely opened. A rope E is iixed at one end at the point Z to the building above the windows C and extends horizontally above a row of windows over a pulley g and thence t-o the lower door of the building. Branch ropes E are attached to the main rope E adjacent to each window C, said branch ropes extending over pulleys 71, near the upper ends of the windows, so as to fall beside the windowframe. The branch ropes E are provided at their lower ends withhooks E2, adapted to engage the staple of the weight f2, and thus suspend the weight and prevent it from operating the sliding bolt e and unlocking the shutters. A pin E3 is fixed in the wallof the Ibuilding adjacent to each window, upon which the hook E2 is hung when not in engagcment with the weight f 2.

The device operates as follows: The parts being in the positions shown at the lett of Fig. l, the hooks E2 of the branch ropes are hooked to the weights f2, and the main rope E is then tightened, so as to raise the weights and have them suspended by the branch ropes E. Then the shutters are closed, they are locked by the bolt e and pin e, as shown at the right in Fig. l. The hooks E2 of the branch ropes E', being connected with the weights f2, prevent the weights from opening or unlocking the shutters. To unlock the shutters, the main rope E is slackened, thus permitting the weights f2 to drop and operate the shutter-bolts, as described. It will be seen that either shutter may be opened by unhooking the branch rope from the shutterweight. From the foregoing description it will be seen that the shutters may be simultaneously locked or unlocked in case of tire or whenever desired, and that if a tire should break out near the main rope and should burn the rope oit the weights to the various Windows would drop and simultaneously unlock all the window-shutters, thereby alording easy access to or from the building. It will be readily seen that the main vropes E may be extended horizontally above the windows on each floor of the building and attached to the shutter-Weights on the various floors in the manner described, so that the shutters on the entire side of the building may be simultaneously operated. It Will be seen, too, that on that class of shutters that are not provided with cross-bars the sliding bolts e may be attached directly to the shutters and operated by the weights, as described, the bolts moving in keepers on the shutters,

vas indicated by dotted lines in Fig. l.

Having thus fully described our invention,

Y We claim as new and desire to secure by Letters Patentdq l. A shutter-fastener consisting in a horizontal bolt to lock the shutters, a pulley f beyond the rear end of the bolt., a chain passing from the said rear end of the bolt over said pulley and provided with a weight to hold the bolt retracted, a pulley h above the pulley f', and a cord or chain passed over said pulley and connected at its lower end to the said weight or its chain to support the Weight and relieve the bolt thereof and perl mit said bolt to rcinain in its locked position, whereby upon slackening said cord or chain I l engage saidl Weights or their chains and hold the Weights elevated to prevent them from retracting the bolts, the pulley g, and the 'main rope E, passedover saidl pulley above the Windows and secured atl to the building, the cords or chains E E being secured to the rope E at their upper ends, whereby by slackening the rope E the Weights Willl be aflL -loWed to fall and retract the bolts, substantially as set forth.
