Patented Sept. 6, 1932 UNITED/STATES PATENT OFFICE] wAIxrEr. R. SCI-ILAGE, OF SAN rRAN IsCO,1 CALIFORNIA, ASSIGNOR 'ro SCHLAGE LOCK C0., or sA FRANCISCO, CALIFORNIA, A CORPOR TION OF CALIFORNIA I' N TUMBLER CYLINDER MOUNTING Application filed ma 14,
1-. In the manufacture of pin tumbler cylinders, castings of difierent slze and shape are usually made to fitvarying types of locks and installations, for instance, a pin tumbler cylinder may be installed in a door knob or 10 it may be installed in an auxiliary lock such as a night latch or the like. In each installation diiierent conditions are encountered and change in the shape and size of the casting is accordingly necessary in all installations. The pin tumbler cylinder should be made readily removable and interchangeable for repairs and also to permit changing of the combination and the cylinder must be rigidly supported when installed.
provide a mounting or housing for pin tumbler cylinders of the character described which permits the use of a standardized pin tumbler cylinder; to provide a housing'in 25 the form of a cylinder or shell which may be pressed or formed from sheet metal or the like; to provide ajhousi'ng which is readily adaptable for installation in varying sizes and forms of locks; to provide a housing which permits ready insertion or removal of a pin tumbler cylinder; to provide a housf ing in which. the pin tumbler cylinder'may be rigidly supported and secured; to provide a housing which permits insertion of stand ardized 'pin tumbler cylinders of varying lengths, for instance, cylinders containing four, five or more pin tumblers; and further, to provide a housing which may be readily anchored, connected or secured with relation to a door or the mechanism to be actuated thereby.
A standardized form ofpin tumbler cylinder together with the housingprovided for its reception is shown by way of illustration in the accompanying drawing,in which Fig. 1 is a perspective View of a standardized form of pin tumbler cylinder,

Referring to the drawing in detail and particularly Figs. 2 to 6, inclusive, A indicates a cylindrical shaped housing provided with an integral bottom or'end section B at one end and an outwardly turned annular flange C at the opposite end. The housing is prefs erably formed of sheet metal or the like and as such may be stamped, pressed, or otherwise formed. The housing is designed for the reception and support of a pin tumbler cylinder such as shown in Fig. 1. This pin tumbler cylinder consists of a cylinder or body-portion 2 which is provided with a plate like .extensiOnB. The cylinder body 2 and the extension 3 encl0se a plug and pins or tum blers of the usual construction and the plug is secured against endwise removal by an end plate or cam-4', the end opposite to the cam or plate 4 indicated at 5 being the end throng which the key is inserted.
The type of pin tumbler cylinder shown in Fig. l is being manufactured by applicant and it .may contain three, four, five, or more pin tumblers as the case may be so as to obtain numerous combinations. All pin tumbler cylinders are uniform in diameterand the dimension of the extension shown at 3 is maintained uniform, hence all pin tumbler cylinders are standardlzed as far as cross sectional shape is concerned but they may be increased or decreased in length in proportion to the number of pin tumblers provided.
The housing indicated at A is particularly designed for the reception and support of a standardized type of pin tumbler lock such as shown in Fig. 1. The bottom or inner end of the housing is accordingly provided with a round opening 2a to receive the body 2 of the pin tumbler cylinder and the bottom is also at 7 in Fig. 6. The face plate, together with the reinforcing plate 6, is provided with a round opening such as shown at 8, this opening being provided for the reception of the front or key end 5 of the pin tumbler cylinder when it is inserted in the housing. The openings-Qa and 8 formed at the respective ends of the housing form seats and supports for the pin tumbler cylinder while the radially extending slot 3a receives the body extension 3 of the pin tumbler cylinder. This slot'engages the sides of the extension 3 and as such secures the pin tumbler cylinder against rotation when supported in the seats provided by the openings 2a and 8.
Means must also be'provided for'securing the pin tumbler cylinder against endwise removal when inserted in the housing. This is accomplished by providing a U-shaped clip 9 such as shown in Figs. 2, 4, and 5; The clip isprovided with a pair of outwardly extending lugs 10 and the slot 3a is cut away as shown at 3?) to receive the lugs 10 of the clip. The clip when applied straddles the inner end of the body extension 3 and the lugs '10 pass through the enlarged portions 36 of the slot 3a. The clip isthen pushed inwardly towards the body portion 2 of the pin tumbler cylinder and as such passes in underlugs 10?) formed by the bottom section of the housing at a point just below the enlarged portions 36 of the slot. The clip'when thus applied secures the pin tumbler cylinder against endwise removal and it may here be stated that clips of varying length are provided. In the present instance afive pin tumbler cylinder lock is shown. A five pin tumbler cylinderv lock extends a short dis tance beyond the bottom end B ofthe housing and the legs of the clip are accordingly made of a length which will just straddle the end of the cylinder body and thereby secure it with relation to the housing. If a four pin tumbler cylinder lock is employed the distance the end of the pin tumbler cyl- The forward end of inder projects will be proportionately de creased and a shorter clip such as shown in Fig. 2 will be employed. On the other hand if a six pin tumbler cylinder lock is employed it will project a greater distance as shown in Figs. 4 and 5 and a clip with longer legs will be employed.
From the foregoing it should be clear: First, that a housing constructed as here shown is capable of receiving a standardized type of pin tumbler cylinder lock such as shown in Fig. 1; Secondly, it will be noted that pin tumbler cylinder locks of varying lengths may be inserted; Third, by merely removing the clip 9 the cylinder lock may be quickly and easily removed for inspection, repair, change, or otherwise, and a new pin tumbler cylinder may just as easily be inserted, hence it is a simplematter to change the combination in a lock provided with a housing or mounting such as here shown.
The present application illustrates two methods of connecting the housing A with relation to the latch or bolt mechanism of a lock. In Fig. 9, the housing A is shown as having a thread formed on the exterior thereof as indicated at 12. The housing A may thus be screwed into the housin D of a mortise type of lock and it may theredoe secured by a screw or look such as indicated at 13.
In Fig. 8 another form of anchorage or securing means is shown. In this instance the housing A isprovided with apair of posts such as shown at 14. These may be riveted or-otherwise secured to the bottom end B of the housing and the outer ends are preferably drilled and threaded as shown at 15. The posts 14:, as shown in Fig. 8, pass through an anchor plate 16 and in this manner secure the bolt housing 17 against removal, the housing A, together with the post 14:, being in turn secured against endwise removal by screws 18 which pass through an escutcheon plate 19 and which enter the threaded ends of the post. Such a connection, by the way, is also adjustable as the posts may be shortened or lengthened or the screws 18 may be shortened or lengthened thus taking care of doors of different thickness. The lock housing is accordingly adapted for ready installation and connection with locks of different types and sizes and when so attached is rigidly secured against removal; the hous ing A being provided with means either in the form of posts 14 or a screw thread connection 12 whereby it may be connected and secured with relation to other lock mechanisms or mechanisms actuated thereby; and furthermore being provided with means for retaining, supporting and securing a pin tumbler cylinder.
The housing is simple and substantial in construction and it is cheap to manufacture as it may be stamped, pressed, or otherwise formed, and as the outer face thereof may be reinforced with an inner plate such as shown at 6 a rather cheap or inexpensive face plate 7 may be employed.
While certain features of the'present invention are more or less specifically described, I wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finishes of the several parts employed may be such as the manufacturer may decide, or varying conditions or uses may demand.
Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A pin tumbler cylinder lock mounting comprising a cylindrical shaped elongated housing, an integral bottom member on the housing, said bottom member having an opening formed therein conforming to the cross sectional shape of the pin tumbler cylinder lock, a face plate secured to the opposite end of the housing and having an opening formed therein to receive the key end of the pin tumbler cylinder lock, said bottom and face plate openings permitting endwise insertion of a pin tumbler cylinder lock, a'U-shaped clip adapted to straddle the inner end of a pin tumbler cylinder when inserted in the housing, and lugs on theclip engageable with the bottom member of the housing to secure the pin tumbler cylinder lock against endwise removal from the housing.
2. A pin tumbler cylinder lock mounting comprising a. housing having openings formed at opposite ends through which a pin tumbler cylinder lock is insertable, means engaging one end of the housing and the adjacent end of the pin tumbler cylinder lock to secure the pin tumbler cylinder lock against endwise removal with relation to the housing, and a pair of posts carried by the housing whereby it is adapted to be secured with relation to a mechanism actuated by the pin tumbler cylinder lock.
3. A structure of the character described comprising a cylindrical shaped housing having an integral bottom member, said housing being open at the opposite end and provided with an annular flange, a face plate adapted to be secured to said flange, and a pair 7 of posts secured to the bottom member;
