Description

Patented Aug. 18, 1953 [UNITED STATES PATENT OFFICE LOCKING DEVICE FOR wiNnoW LA'rcHEs Neil 0. Holmsten, new Rochelle, N. Y. Application December 1949, Serial No. 134,576
6 Claims.
This invention relates to locking devices for rotatable latches of the type used for hinged windows and the like and has for an object to provide a built-in, unitary latch and lock which is compact and dependable and is suited to commercial production methods.
Other objects and advantages will be apparent as the nature of the invention is more fully disclosed.
The novel features which are characteristic of this invention will be better understood from the following description, taken in connection with the accompanying drawing, in which a specific embodiment has been set forth for purposes of illustration.
In the drawing:
Fig. 1 is a front elevation of a latch and lock embodying the invention as applied to a window frame;
Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1;
Fig. 3 is a horizontal section taken on the line 33 of Fig. 1;
Fig. 4 is a rear elevation of the latch;
Fig. 5 is a section taken on the line 5-5 of Fig. 3; and
Fig. 6 is a section taken on the line 6-6 of Fig. 4.
Referring to the drawing more in detail the invention is shown as applied to a latch for a window or the like having a sash I closing against a fixed frame II. The latch comprises a base plate I2 attached to the sash HI closing against a fixed frame II. The latch comprises a base plate 12 attached to the sash H) by suitable means such as non-removable screws [3 and carrying a cylindrical support M. A hub I carrying a latch finger l6 and a handle I! is journalled on the support [4 for rotation. The latch finger I6 is adapted to engage a keeper which is attached to the fixed frame II.
A lock barrel 2! is secured in the support [4. The barrel 2! has a key 22 which prevents rotation thereof. A key actuated lock cylinder 23 is journalled to rotate in the barrel 2i and is secured against rotation therein by removal of the key. The lock cylinder and barrel are of standard construction and may be of any type actuated by a key for securing or releasing the cylinder for rotation. The cylinder is eccentrically mounted in the barrel 2| and the barrel 2| is eccentrically positioned in the support I4 in such a manner that the cylinder 23 is centered in the support M.
The base plate 12 is formed with a recess 24 in its under surface in which a disc 25 is seated. Screws 26, extending through arcuate slots 21 in the base plate [2 secure the disc 25 to the hub l5 for rotation therewith. The slots 2'! limit the rotation to about as shown. The screws 26 are formed with shoulders 28 and cylindrical surfaces 29 to provide smooth surfaces sliding in the arcuate slots 21. A rectangular tongue 30 on the end of the cylinder 23 is seated in a slot 3| in the disc 25 to cause the disc and cylinder to rotate as a unit.
In the latch and lock above described a standard lock barrel and the latch hub are concentrically mounted, one on the inside and the other on the outside of a fixed cylindrical support and are joined by a disc which is entirely concealed in the base plate and cannot be removed after the base plate is attached to the sash. The size of the hub is not appreciably greater than that of a standard latch without locking means.
The latch as above described is applicable to various uses such as swinging windows or doors, automobile doors, or the like. The latch finger and handle are illustrative only and may take any of the usual latch forms such for example as a sash latch for sliding windows. Various adaptations will be apparent to a person skilled in the art.
What is claimed is:
1. A locking device comprising a base plate to be attached to a member to be locked, a cylindrical support carried by said base plate and extending outwardly therefrom, a hub carrying a latch member journalled on said cylindrical support for rotation thereon, a lock barrel fixed in said cylindrical support, a key actuated lock cylinder rotatable in said barrel and adapted to be locked thereto against rotation, said base plate having an opening registering with said cylnider and an arcuate slot registering with said hub, a securing member disposed on the under side of said base plate attached to said cylinder to rotate therewith and securing means extending through said slot to secure said member to said hub to cause the cylinder and hub to rotate in unison.
2. A locking device, as set forth in claim 1, in which said cylinder is eccentric with respect to said barrel, but concentric with said hub.
3. A locking device, as set forth in claim 1, in which said securing means comprises a pin attached to said securing member and extending through said slot to secure the same to said hub.
4. In a locking device, as set forth in claim 3, a tongue on the end of said cylinder securing the same to said disk.
3 5. A locking device, as set forth in claim 1, in which said slot has ends positioned to form stops to limit the rotation of said hub.
6. A locking device comprising a base plate to be attached to a member to be looked, a cylindrical support carried by said base plate and extending outwardly therefrom, a hub carrying a latch member for. .rotation therewith. and being journalled on the outside of said cylindrical support, a key-actuated lock cylinder rotatably mounted inside of said support and adapted to 4 References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 450,220 Crady Apr. 14, 1891 916,826 Baldwin Mar. 30, 1909 V, 1 1,339,721 Shaw May 11, 1920 1,424,686 7 V S ommers Aug. 1, 1922 1,515,611 iQfConnor 1 N0v.118, 1924 2,475,951 Floraday July 12, 1949 FOREIGN PATENTS Number Country Date 1 2,405 Great Britain Feb. 7, 1905 483,934 Germany Oct. 7, 1929
