With the key thus positioned and shoved all the way into the keyway, the key can be turned in the casing, and since the drive pins in effect constitute torque transmitting splines, rotation of the key is imparted to the spindle. With these and other objects in mind, the manner in which the invention achieves its purpose will be appreciated from the following description and the accompanying drawings. 9, the dome or cup-shaped protective collar has a plurality of lugs or tangs 50 on its peripheral edge, which are bent down over the inner face of the iiange 9' to hold the collar in place, but this assembly cannot be effected until after the spindle has been assembled with the casing. The inner cylinder assembly further includes the locking mechanism which comprises an outer sleeve, a plug or barrel within the sleeve, said plug including biased axial tumblers in tumbler passages, and a rotatable spindle with axially slidable tumblers mounted in axial passageways in the spindle. Briefly, the present invention comprises an axial pin tumbler lock with a removable core. The cross bore 43 is large enough to accept the balls 42 which, however, are yieldingly urged out of the bore by a spring 44 confined between the two balls. said ball being of a diameter greater than the distance between the wall of the counterbore in the casing and the surface of the central part of the spindle head portion which defines the inner wall of the annular keyway. A tubular lock and key A tubular pin tumbler lock, also known as a circle pin tumbler lock, radial lock, or the trademark Ace lock popularized by manufacturer Chicago Lock Company since 1933, is a variety of pin tumbler lock in which a number of pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape. The Series 65 Cam Lock houses our patented, manipulation-resistant AXIAL Pin Tumbler mechanism in a resilient hardened steel shell. Another feature of this invention resides in the provision of detent means to hold the key in its fully inserted psition against the thrust of the tumbler springs thereon, to thus obviate the need for holding the key in manually as it is turned. With such alignment the spindle will be freed for rotation. 4, 1952, illustrates a lock of this type. 8, the protective collar 47' is dome or cup-shaped to afford even greater protection.
