DOOR-FASTENER.
SPECIFICATION forming part of Letters Patent No. 781,743, dated February 7, 1905. Application filed May 9,1904. Serial No. 206,974.
To (1, who/It if 'II'MLZ/ concern.-
Be it known that I, MARVIN 0. Korea, a citizen of the United States, and a resident of Somerville, in the Commonwealth of Massachusetts, have invented an Improvement in Door-Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
It is often convenient to have means to secure a door partially open and yet permit the door to be locked when closed or opened freely, as may be desired.
Accordingly my present invention has for its object the provision of such means in compact, ornamental, and simple form, my mechanism including a stud which is fixed permanently on one of the relatively moving parts and a movable member of special shape, as explained later, fastened to the other part, (the said parts being the door and the doorcasing,) and in its preferred form the stud is mounted on the door and the movable member is mounted on the casing and is preferably pivoted so that it will swing down or up or horizontally, according as the door is to be locked, closed, or unlocked or locked partly open.
The constructional details of my invention will be further pointed out in the course of the following description, reference being had to the accompanying drawings, in which I have shown a preferred embodiment of my invention.
In the drawings, Figures 1 and 2 show in front elevation the two members or parts of my invention. Figs. 3 and 4 are views thereof in side elevation. Fig. 5 is a top plan view showing the parts in proper position for permitting the door to stand ajar. Fig. 6 is a view on a reduced scale showing the parts in position to lock the door closed, said figure being taken looking at Fig. 5 toward the right, the movable member being swung downward. Fig. 7 is a similar view to Fig. 6, showing the parts in position to permit the door to open freely. Fig. 8 is an end elevation looking at Fig. 4 toward the right.
As hereln shown, a stud (1, preferably having a head u, pro ects rigidly from the baseplate a? and is adapted to be screwed adjacent to the front edge of the door A, as indicated in Fig. 5. Cooperating with the stud u is a movablemember, preferably pivoted, said member being herein shown as comprising a plate or disk a, mounted on a bearing-plate a, secured by screws (1 to the door-casing a, as clearly shown in Fig. 5, said plate (1 being firmly pivoted by a heavy screw 11 and carrying at its front a loop a, of wire, one leg of which is fastened at a" to said base-plate short of the center and the other leg at a beyond the center for purposes presently to be described. A resistance-post o projects from the plate a to strengthen the long leg of the loop, as shown in Figs. 2 and 6. This loopu, of wire, constitutes a longitudinal way for interlocking with the stud u, and the wire projects from the plate 11 sufliciently to permit the head a of the stud to engage beneath the opposite parallel and overhanging sides of the loop and be retained thereby, as clearly shown in Fig. 5, and to permit the head of the stud to enter freely I offset the end a of the loop, as clearly shown at a in Fig. 8. The plate (L3 is pivoted with its center directly opposite the stud (L when the door is closed, and therefore when the member a is moved horizontally, as shown in Fig. 5, the stud is in accurate alinement for moving outwardly therein. By permitting the member a to fall or swing from said horizontal position downward to the position shown in Fig. 6 it brings the long leg of the loop directly across the path of the stud, thereby constituting a barrier which positively locks the door closed. On the other hand, when the retaining device or pivoted member is swung upwardly into the position shown in Fig. 7 the short leg of the loop is out of the way of the stud, thereby affording a release-passage permitting the door to freely open.
In use if it is desired to lock the door the retainer ('68 is simply permitted to fall, thereby automatically assuming the position shown in Fig. 6 and interposing the barrier formed by the long leg of the loop against the stud a, securely locking the door closed. If the door is not quite closed when it is desired to lock it, the retainer a may he pulled forcibly downward, thereby exerting a strong leverage for tightly shutting and locking the door. Vhen the door-bell rings, the person responding thereto simply raises the loop a from the position shown in Fig. 6 to a horizontal position, thereby bringing the loop into horizontal alinement with the stud, permitting the door to be opened to the extent indicated in dotted lines, Fig. 5, and no farther. Thisgives the person a sense of security and yet permits conversation and observation through the partly-opened door. If it is desired to open the door entirely, the retainer is simply moved to the position shown in Fig. 7, thereby bringing the release-passage opposite the stud, so that there is nothing to interfere with the swinging of the door, and the latter can therefore be freely opened. By placing the long leg of the loop on the other side of the pivot or when the retainer, as shown, is used on a door opening the other way the unlocked position will be down instead of up. The retaining member is secured to the doorcasing to swing in a plane at right angles to the stud a, and the loop a extends parallel to the disk a excepting at its inner end, where said loop is bent perpendicularly toward said disk and rigidly secured thereto, one leg of said loop projecting in the length of the loop beyond the pivot-point to constitute a barrier for exerting the strong leverage and locking the door, as explained above, and the other leg of the loop terminating short of the pivotpoint, so as to permit the door to open freely when theloop is swung into the position shown in Fig. 7 v
I am aware that various devices have been proposed in which studs or bolts and loops have been used; but in my device the loop is rigid with the pivoted disk and can only swing in the vertical plane transversely of said stud, and the stud is immovably held in the baseplate (6 which is rigidly secured to the door, so that the stud extends in longitudinal alinement with the pivot of the retainer-disk.
i/Vhat I claim as new, and desire to secure by Letters Patent of the United States, is
1. A door-fastener,comprising a fixed member secured to a door and having a horizontal stud projecting immovably therefrom, and a retaining member pivoted to the door-casing to swing vertically in a plane transversely of said stud, the pivot thereof being in longitudinal alinement with said stud when the door is closed, said retaining member having means cooperating with said stud to lock the door closed when extending vertically in one direction and means permitting the door to open when extending vertically in the opposite direction.
2. A door-fastener, comprising a fixed stud, and a retainer, the latter consisting of a disk centrally mounted on a horizontal pivot in longitudinal alinement with said stud, said disk having a stud-receiving way projecting rigidly therefrom, said way having a lateral opening opposite the center of the disk for permitting the door to open freely, the way being closed at its outer end to limit the sliding movement therein of said stud when the way is turned into horizontal position, and having its side opposite said lateral opening extended approximately across the disk to constitute a barrier to engage the stud for forcing the door tightly closed as the retainer is turned on its pivot into door-closing vertical position. 3. A door-fastener, comprising a stud, and a retainer cooperating therewith, consisting of a disk centrally pivoted and an oblong loop extending in a plane parallel to said disk excepting at the disk where the ends of the loop are bent inwardly and secured rigidly to said. disk, one of the sides of said loop extending beyond the pivotcenter and the other terminating short thereof.
4:. A door-fastener, comprising a stud, and a retainer cooperating therewith, consisting of a disk centrally pivoted and an oblong loop extending in a plane parallel to said disk excepting at the disk where the ends of the loop are bent inwardly and secured rigidly to said disk, one of the sides of said loop extending beyond the pivotcenter and the other termi- MARVIN O.
