ARNOLD WV. ZIMMERMAN, OF WASHINGTON HEIGHTS, ILLINOIS.
DOOR-BOLT.
SPECIFICATION forming part of Letters Patent No. 444,869, dated January 20, 1891.
Application filed February 28, 1890. Serial No. 342,093. (ModeL) To all whom it may concern:
Be it known that'I, ARNOLD IV. ZIMMER- MAN, a citizen of the United States, residing at YVashingt-on Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refrigerator-Door Fasteners, of which the following is a specification.
My invention relates to fasteners for doors or other closures which are designed to be air or liquid tight, and it is particularly applicable to the fastening of doors of refrigeratorcars. Such doors are usually provided with a flexible packing around their margins and between their abutting edges, and when first constructed it is exceedingly difficult to open or close them,and the same trouble is experienced when the swelling of the doors under the influence of moisture occurs. Devices have therefore been proposed for rendering the opening and closing of these doors more easy and for locking them when closed, and my invention relates to improved means of this character.
In carrying out my invention I provide keepers near the edge of one of the double doors, within which keepers is movably confined a reciprocating-bar having its ends projected beyond the ends of the door and bent at an angle to the body of the bar to provide en gaging-catches, bothof which incline preferably in the same direction. Apertures are provided in the door-frame at each end of the door to receive these catches, and a catchplate is secured on the door near its midheight and having an inclined slot to receive a stud projecting from the side of the reciprocating bar. A lever is pivotally connected to the bar below the catch and a link eonnects said lever between its ends with one of the keepers.
In the accompanying drawings, Figu rel is a perspective view of a frame having set therein doors to which are applied my fastening devices. Fig. 2 is an elevation of the edge of the door which carries the fastening-bar, the frame being shown in section. Fig. 3 is 'a View similar to Fig. 1, with the door partially open; and Fig. i is a view similar to Fig. 2, but with the door partially open. Fig. 5 isa transverse section through the doors and through the reciprocating bar above the central catch, which with other part shows in plan.
In the drawings, A indicates the door-framing, which is provided at the ends of the opening with the mortised seats B B, which will be adapted to receive therein the catches. I prefer to provide these seats on one of their sides with plates 6, inclined so as to furnish a surface against which the catches may act in opening or closing the doors.
0 0 represent the doors, which will be hinged to the frame in the usual manner, and which close with their free margins against each other, their edges being beveled, as shown in Fig. 5, and to these meeting surfaces will be applied the packing c. On the outer surface of the door 0 a locking plate or catch D is secured, having a flange projecting at an angle to the surface of the door, and in this flanged projection is provided the inclined locking-slot d.
E represents keepers secured to the door 0 near its inner edge, toward its ends, respectively, and within these keepers slide the reciprocating bar F, the upper end of which is bent, as at f, to enter the mortise at the top of the door; The lower end of bar F is bent into hook form, by preference, as show-n at f. The bar carries opposite the slot in the catch-plate d the stud F, which is adapted when the bar is reciprocated to enter the slot in the locking-plate, riding on the upper wallthereof in the operation of closing the door and on the lower wall in opening the door.
G is an operating-lever, which is pivoted at one end to the bar F, and is pivotally connected between its ends to the link H. As shown in the drawings, the lever G is pivotally connected to timing g, projecting from the side of the bar F, and the inner end of the link II is pivotally connected by a pin It, passed through the ears 1' of a keeper I, secured to the door opposite the plate E and inclosing the bar F on three sides and forming the guide therefor. The inner wall or side of this keeper I is slotted at t", and through this slot the locking-stud F projects.
In operation, if it be desired to fasten the door, it may be brought to the condition shown in Fig. 3, and then the lever G will be grasped at its outer end and pulled down, moving itin the arc of a circle, the effect of which will be to cause the reciprocation of the bar F, the outer end of the link H forming a movable fulcrum over which the strain is exerted. As the bar reciprocates, its bent ends will be guided into the mortise-seats and the fixed pin on its edge will enterthe slot in the locking-plate. As soon as these locking projections enter their respective seats the operator hasthe aid of three inclined planes, one at either end of the door and one near the middle thereof, supplemented by the lever to aid in completely closing the door, and it will be apparent therefore that a door which could scarcely be driven shut with a hammer, owing ,to the resiliency of the packing, can be readily closed by myimprovements without great exertion. \Vhen the door is closed, the lever will have been brought intoline with the link and both will lie against the side of the bar F, thus obviating the accidental unlocking of the door even without the aid of additional locking devices. When the door is to be opened, the lever will be moved back to its original position and the cam-faces of the locking ends of the bar and of the lockingcatch will assist to open the door readily.
I have shown and described a pair of doors whose edges close in contact; but it is evident that my improvements are equally applicable to a single door, and that modifications may also be made in the structural features.
I claim-- 1. A fastening for doors, comprising, in combination, an endwise-movable bar having a sliding connection with the door and projecting bent ends, seats in the frame to receive said ends, and an operatinglever pivotally connected with the bar and with the door, said bar having a fixed stud adapted to engage a catch secured at the side of the door,
.substantially as described.
2. A fastening for doors, comprising an endwise-movable bar having a sliding connection with the door and its ends terminating in pro jecting catches, seats in the frame at the ends of the door to receive said catches, an operating-lever pivotally connected with the bar, a swinging link having oneof its ends connected with the door and its other end with the operating-lever, whereby to provide a movable fulcrum, a locking pin or stud secured upon the bar, and a locking-plate secured at the edge of the door and having an inclined slot to receive said locking-pin,substantially as described.
3. A fastening for doors, comprising, in combination, an endwise-movable bar having its ends bent to provide engaging-catches whose surfaces are inclined planes, a locking-stud secured upon the bar, seats adapted to receive the ends of the bar and the locking-stud, an operating-lever pivotall y connected at one of its ends to the bar, and a swinging lever pivotally connected at one end to the bar and at the other to the door, whereby to provide a movable fulcrum, substantially as described.
4. A door-fastening comprising. in combination with a pair of doors whose edges are to be closed in cont-act, an endwise-movable .bar mounted to slide in keepers secured to one of the doors, said bar havingits ends bent downwardly and in the same direction to provide locking-catches whose bearing-faces are inclined planes, seats to receive said catches, a locking-stud secured with the bar near its center, alocking-plate secured on the other door and having an inclined slot therein to receive the locking-stud, an operating-lever pivotally connected at its inner end to the bar below the central catch, and a swinging link having one of its ends pivotally connected to the door opposite the central locking-catch and its other end pivotally connected to the operating-lever, all substantially as described.
