aymywwk QFF .oHAnL s w. MEADowonornsn, or P ILADELPHI PENNSYLVANIA, ASSIGNORTO MILLER LOCK COMPANY, or PHILADELPHIA; PENNSYLVANIA, A CORPORATION or PENNSYLVANIA. A
To all whom it may concern:
Be it known that I, CHARLEs MEADow CRO FT,SeIllOI, a citizen of the United States,
residing in :Philadelphia, Pennsylvania,
have invented certain Improvements in Key- 18 asp'ecification. 1 My invention relates to certain improvements in key-"bearings of locks of the type known as cupboard. ordrawer locks.
r These locks are usually made with along barrel projecting. from thecasin'grthrou h the woodwork-of the door, or. drawer, t e
end of this barrel being exposed through the outside of th'e idoor, while: the casingof the lock issecure'd-on the inside; A. I One obj ect'df my inventionis to provide a key bearing -j wh'ich' is adapted to rotate in thisbarrel and to support the'key' so that it will properly actuate the mechanism of the lock. A A A A, A
A further object of the invention is to manufacture the key bearing from" sheet metal bent into shape.
In the accompanying drawings: Figure 1* is a. face view of a cupboard lockto which -my invention is applied; Fig. 2 is a rear view of the casing; Fig. 3 is a transverse sectional view on the line 3-3, Fig. l, the mechanism within the casing, with the exception of the key bearing being omitted. 1
g. 4: is a perspective view of the key bearing; I
Fig. 5 is a plan view; Fig. 6 is a side view; Fig. 7 is a front view; Fig. 8 is a rear end view;
Fig 9 is a perspective view of a portionof the1 key which is adapted to the key bearing; an A Fig. 10 is a view of the blank from which A the key bearing is formed.
has
The casing of the lock has a body portion 1 and a cover plate 2 to which is secured the barrel 3. This barrel is of difierent lengths, according to the thickness of the woodwork of the door, or drawer, so that while the lock is secured to the inner side of the door, or drawer, the outer end of the barrel is flush with the outer surface thereof.
Mounted within the barrel is a key hearing 4, made as shown in Fig. 4, havinga cylindrical end portion 5, which is of the same diameter as the interior'of the barrel and Specification or as I'atent. Application filed July 10, 1918. Serial No. 244,267.

( PatentedDec.3,1918.
fits against the internal flange 6 at the outer end of the barrel, the flange holding it against outward movement.
7 is a key slot formed in the end portion 5 and this end portionhas a depression 8,
as shown, forming a guide for the key. The slot conforms to the notch 9 in the flange 6 of thebarrel. 10 is a downwardly project'- ing bottom support for the key, bent, as
shown in Fig. 6, so as to be in line with the ment in the casing Projecting beyond the A shoulders is-a bearing portion 12 having upturned flanges 1 3, which are spaced apart inform the. rearkeywayj This portion is rounded so as to' fit the circular opening in the body portion, as clearly shown in Fig. 2.
I In orderg to form a guide for the key in addition tothe guide to the end portion 5, I provide armsl l, which are" bent inward, as shownin Fig. '5, and arespaced apart sufficiently to allow for the passage of the key. 30
These arms are preferably bent outward A so that their ends'15 will fit against the interior of the barrel 3 and will act to steady the key support in the barrel and will also A act to-hold. the key bearing in theposition in which the key leaves it.
My improvedkey bearing is made from sheet metal cut in the form shown in Fig. 10 and the parts are bent on the dotted lines to form the bearings shown in Figs. 4, 5 and 6. 90.
From the above description it will be seen that I can make a'key bearing for a lock from sheetmetal bent into shape which will be comparatively cheap as very little metal A is employed and which will provide means for properly guiding the key and will be firmly supported in the lock casing.
- I claim:
1. The combination in a lock, of a casing having a barrel; a key center mounted in the barrel and having a slotted end section adapted to close the end of the barrel; and having a rearwardly extending bottom support terminating in a shoulder fitting against the body portion of the casing and also having a flanged extension fitting an A opening in the said body portion.
