FASTENER FOR KEY CYLINDERS Filed Aug. 6, 1929 Patented Dec. 29, 1931 UNITED STATES 'A EN 0mm:

ELMER B. STONE, or new BRITAIN, CONNECTICUT, assrenon 'ro THE AMERICAN Hann- WAR-E conroaarion, G1 NE BRITAEIJ, CONNECTICUT, A CORPORATION OF CON- NECTICUT V I I rasmn snn non KEY CYLINDERS Application filed August 6, was. 'SeriaL'No. ssaeas,

My invention relates more particularly to means for securing a key cylinder in a wooden structure as, for instance, in a drawer or similar device, and an object of my inyention, among others, is the production of a fastener for such structures that shall be particularly effective for securing the key cylinder or barrel in place.

Forms of devices embodying myi'nvention and in the construction and use of whichthe objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view of the inner surface of the front of a drawer or similar device showing my improved fastening means for attaching a key cylinder in place.

Figure 2 is a view in section on a plane denoted by the dotted line 2-2 of Figure 1.

Figure 3 is a view in cross section on a plane denoted by the dotted line 33 ofFigure 1.

Figure 1 is a View of the inner surface of the front of a drawer or similar device, illustrating a little difierent means for attaching the key cylinder or barrel in place and embodying my invention.

Figure 5 is a view insection on a plane denoted by the dotted line 55 of Figure 1.

Figure 6 is a view illustrating still another method of securing the barrel in place.

Figure 7 is a view in section on a plane denoted by the dotted line 77 of Figure 6.

In the accompanying drawings the numeral 8 indicates the front of a drawer or similar device that is formed of wood or other fibrous material and that is provided with a hole 9 in which a key cylinder or barrel 10 is rigidly fixed, this cylinder being of any ordinary'form and construction. The inner end of the key cylinder is threaded, as at 11, for the purpose of receiving my improved fastening means.

This fastening means comprises a plate 12, in the form of a disk, having a hole through which the cylinder extends, this holebeing shaped, in connection with the cylinder, to prevent the latter from'turning independently of the plate. In the structure, "herein shown the cylinder is cut away on one side forming a flat portion 18 that is received against a flat portion on one side of the hole through the plate. Prongs 1a are projected from the inner side of the plate at suitable intervals apart andare shaped to pierce the materialof which the drawer is formed.

-A nut 15 fits the screw-threaded end of the cylinder orbarrel 10, and when this nut is screwed in place, as by means of a wrench or other tool, the prongs 14 will be forced into thematerial of the drawer 8, the shoulder under the escutcheon on the face of the cylinder will be drawn tightly against the face of the drawer front, and by reason of the fact thatthe plate is secured against turning movement by the prongs piercing the drawer V materialthe cylinder is held against rotation by reason of the flat portion 13 fitting the flat portion of the hole through the plate. Any suitable means, as a tongue 16, may be secured to the back end of a plug 17 as a means for operating a locking mechanism for securing a drawer.

In that form of the device shown in Figures 4 and 5 the, cylinder or barrel 10 is cut away or flattened on one side at 13 as described with respect to the other structure. A plate 18 has a hole flattened on one side to fit the end of the cylinder, and this plate is secured to the back surface of the drawer front as by means of screws. A nut 19 fits the screw-threaded end of the cylinder to draw the later firmly to its seat in the same manner as 111 the device heremabove described. In that form of the device shown in Figures 6 and 7 the cylinder is of the same form as hereinabove described, with the exception of the fiattene'dportion. As a substitute for this flattened portion a groove 20 is formed lengthwise in the outer surface of the cylinder and a key 21 is located partially in said groove and partially in agroove 22 in the wall of the hole'in the drawer in which the cylinder is located. A. nut 23 is secured to v the screw-threaded end of the cylinder in the same manner asjshown with respect to the device of Figures 1- and 5., thenutcovering the end of the key 21 and thereby retaining the latter in place.

In accordance With the provisions of the patent statutes, I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim- 1. In combination with the key cylinder of a lock and a part within which said cylinder projecting to the back thereof, a holder e11- gaged with the projecting end of the cylinder at the back of said part to prevent rotation of said cylinder, and means movable independently of said holder for securing said cylinder and for preventing disengage ment of said holder from said part.

2. In combination With the key cylinder of a lock and a part within which said cylinder is located, a holder to prevent rotation of said cylinder, and a screw threaded member engaging a screw threaded end of said cylinder to secure the latter in place and to prevent disengagement of said holder from said part.

3. In combination with the key cylinder of a lock and a part within which said cylinder is located, a holder having an opening of non-circular shape fitting said cylinder to prevent it from rotation, and means in engagement with said cylinder and said holder for securing said cylinder and for preventing disengagement of said holder from said part.

4;. In combination with the key cylinder of a lock and a part within which said cylinder is located, said cylinder having a screw threaded end flattened on one side, a holding member fitting the flattened portion of the cylinder to prevent rotation thereof, and a screw threaded member engaged with said cylinder to secure it in place and rest against said holding member to support it. i

5. In combination with the key cylinder of a lock and a part within which said cylinder is located, a holding plate fitting over the end of the cylinder and engaged therewith to prevent independent rotation of said plate and cylinder, prongs projecting from said plate, and a nut engaged with the screw threaded end of the cylinder and adapted to press against said plate.

6. In combination with the key cylinder of a lock and a part within which said cylinder is located, said cylinder being threaded on its end and having a flattened side, a plate having an opening to fit the end of the cylinder to prevent independent rotation of said cylinder and plate, prongs integrally formed on said plate, and a nut secured to the threaded end of the cylinder and pressed against said plate.
