Application filed August 5, 1919. Serial No. 315,373.
' rim cylinder lock for thepurpose of holding the cylinder against bodily rotation when mounted. Cylinders of this type are generally placed within a circular recess formed therefor in the supporting door or other member and secured in position by engagement with the lock of screws or the like which pass through the back plate.
The back plate is intended by its frictional engagement with the back plate of the lock to hold the cylinder against bodily rotation. It is a fact, however, that such securing means are not entirely eflective. The present invention contemplates the provision of locking devices which may be readily applied to the cylinder of the lock and engage the door .or other member in such manner as to positively hold the cylinder against rotative movement. In the illustrated embodiment the improved devices are shown in the form of two segments so shaped as to lie in snug engagement against the cylinder of the lock and each formed with an ear or the like intended to engage a groove or recess cut in the door or other member along the periphery of the opening in which the cylinder is mounted. In the drawings- Fi re 1 is a view in front elevation showing a standard type of cylinder in position in the door or other member.
Fig. 2 is a view in elevation of the reverse side of the cylinder shown in Fig. 1, the back plate being omitted. V
Fig. 3 is a view partly in vertical section and partly in elevation of the cylinder shown in Figs. 1 and 2, with the back plate in position.
Fig. 4 is a detail View of the improved locking segments.
While the invention is not to be limited to the particular type of cylinder with which the improved devices are useful, it is true that these devices are designed for rim cyl- V inder locks of such form as indicated by a I reference to character a'fin the drawing. Such a lock is mounted in a cylindrical channel a which is bored in the-door b or other member towhich the lock isapplied, the cylinder of the lock resting rather snugly within the channel a. 'Ordinarily the cylinder a would be' maintained in position by some 7 such attaching means as are illustrated by the small bolts '0 which pass through a back plate a} and are threaded into lugs a formed with the cylinder The usual front plate a of the cylinderis drawn into snug 'engagement wi'th the wall of the door b by the action of the bolt 0, through the back plated. Such a means of attachment is not always satisfactory, since it is foundjthat the cylinder has a tendency to rotate aboutits own axis within the channela under the pressure imposed on it by the key. The improved devices for holding the cylinder against such rotation comprise, as an arti-' cle of manufacture, generally semi-cylindrical segments 6 which areso shaped as to conform to the configuration of the cylin der and bear snugly thereagainst at opposite sides.
also be of generally semi-cylindrical outline, these ears being adapted to rest snugly within grooves or recesses I) cut, as at diametrical points, along the periphery of the channel a in which the cylinder is placed. The segments e bear against the cylinder of the On the outer edge of each of the. segments 6 is formed an ear 6 which may lock or against any irregular portions on its surface in such manner as to constitute essentially clutch elements interposed between the door 12 and the cylinder. Any tendency of the cylinder to rotate bodily is counteracted completely by the engagement of the ear 6 with the walls of the grooves I) in the 7 door.
It will be understood from the description given that the inventionis not limited to the precise'shape of the segments 6, 'nor to the shape of the ears 6 thereon, nor to the channels in the door with which these ears cooperate. Nor is the invention limited as to the number ofsuch segments employed, since all of the features mentioned may depend somewhat upon the particular shape of the exterior of the cylinder of the lock or upon the particular conditions under which the cylinder is mounted. Generally speaking, however, it Will be found that segments of the type illustrated in Fig. l may be made up as an article of manufacture and sold for use on many of the standard types of rim cylinders now on the market.
Reference is to be had to the accompanyvided With a channel to receive the cylinder,
and said channel Wall being provided with a recess, a segment engaged With the exterior of the cylinder of the lock, and an ear carried with the segment and adapted to ,rest in said recess to hold the cylinder 7 against rotation.
2. In combination with a rim cylinder lock and a supporting member therefor provided With a channel to receive the cylinder snugly, said channel Wall being provided with diametrically opposed recesses, two genermounted.
ally semi-cylindrical segments having their inner edges curved to iit snugly the cylinder of the lock and their outer edges curved to conform to the Wall'of the channel and each provided With an ear 'to engage one of the said recesses.
3. As an article of manufacture, a segment formed to engage snuglyithe exterior of the cylinder of a rim cylinder lock and provided 'With an ear to engage the supporting member in which the cylinder is 4. As an article of manufacture, a generally semi-cylindrical segment having its inner edge curved to fit snugly the cylinder of 1 a rim cylinder lock and having its outeredge curved to conform to the Wall of the channel in Which the cylinder is mounted and provided With an ear to engage the Wall of the channel. p r K c This specification signed this 29th day of July, A. D. 1919. 1
