SPECIFICATION forming part of Letters Patent No. 443,418, dated December 23, 1890.

Application filed September 6, 1890. Serial No. 364,135. (No model.)

To all whom it may concern.-

Be it known that I, FRANK W. WALLACE, of Utica, in the county of Hinds and State of Mississippi, have invented new and useful Improvements in Bolt-Operating Devices for Doors and Vt indow Shutters or Blinds, of which the following is a full, clear, and exact description.

This invention is more particularly designed. to be applied to double or half doors which meet in the middle, such as used in stores, halls, and other places; also to double or divided window shutters or blinds.

'It relates to double bolts for such structures arranged, say, at top and bottom thereof; and it consists in novel means, substantially as hereinafter described, and more particularly pointed out in the claims, for simultaneously operating or drawing said bolts instead of, as is sometimes'done, pulling on a hanging chain with one hand to draw back the top bolt and stooping to pull on the other or lower bolt with the other hand.

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 all the figures.

Figure 1 represents a view in perspective of a double or divided door and door-frame with my invention applied; Fig. 2, a vertical section of the same, upon a larger scale, on the line 2 2 in Fig. 1; and Fig. 3, a longitudinal section upon the line 3 3 in Fig; 2.

AA indicate two half or single doors hinged at b b to the door-frame and meeting, when closed one after another, in the middle, and

usually provided with a lock applied to the door that shuts last, made to engage by its latch or bolt with the other door.

B B are the bolts applied to the doorA that shuts first. These bolts are used both on the top and bottom of said door, and are arranged to slide up and down, so as to engage with and disengage from keepers C C in the upper portion of the door-frame and door sill. Said bolts are spring ones that is, they are fitted within their cases D D with springs c c, which, although here shown as spiral ones, may be of any other suitable kind, and which serve to shoot the bolts into and hold them in engagement with their keepers O 0. Furthermore, the bolts B B are preferably latch ones that is, are made with beveled noses-and the keepers with which they engage also made beveling on the engaging ends of their faces to provide for the bolts automatically drawing inward when shutting the door, after which they engage themselves with their keepers.

I To open the door to which the bolts B B are applied, a lever G, pivoted horizontally, as at (l, to a carrier II and arranged intermediatel y of said bolts, is used, and this lever is connected on opposite sides of its fulcrum d by wires or rods 6 e with the bolts B B, so that .by working said lever on its fulcrum (Z both the top and bottom bolts will simultaneously and by'the same motion be drawn out of engagement with their keepers O 0, when the door may be opened. The carrier H, to which the lever Gr is pivoted, is united by a vertical 7o hinge f with the door back of the inner end of the lever, whereby the lever G may be moved outward or away from the door, as shown in Fig. 3, to conveniently manipulate it on its fulcrum (7. to operate or disengage the bolts from their keepers, as described; but when the lever is not being used the hinged carrier H serves to allow of said lever shutting up against the door and out of the way, as shown in Fig. 1. The carrier H is or may be provided with a stop g, that when the lever G with its hinged carrier II is swung outward,

as in Fig. 3, serves to arrest the same in such position for the purpose of more conveniently manipulating and operating the lever. The same combination of bolt-operating devices may be applied to double or divided window shutters or blinds; but in this case the bolts should be on the shutter or blind which closes last, and which usually holds the other shutter or blind shut by overlapping it at the meeting edges of the two blinds or shutters.

By hinging the operating-lever, as do scribed, to a carrier secured to the door, so that said lever when required to operate the bolts can be swung out to a position at right angles to the plane of the door, a person facing the door can operate the lever to greater advantage without any risk of chafing his hand by contact with the door than if said lever 10o were operative in the plane of the door and close up to it, yet; said lever when not being operated can shut close down against; the door, so as to be out of the way.

Having thus described my invention, I elann as new and desire to secure by Letters Patent 1. In bolt-operating deviees for doors and window shutters or blinds, the combination,

IO with spring-actuated bolts oppositely arranged, of a carrier hinged to swing; in a horizontal plane, a lever pivoted to the carrier to swing in a vertical plane, and wires or rods connected to the bolts and to the lever on [5 opposite sides of its fulcrum, substzuitiullyas described.
