The reference numeral 9 what may be referred to as e key plug which is designates diametrically opposite grooves which adapted to be removed when not in use, extend longitudinally in the bore 'l and which Other objects of the invention are to provide a communicate with the counterbore 8. Fixed on look of the character described which will be the inner end 0f the barrel 6 is a metallic plate 15 comparatively simple in construction, Strong, I0 which is recessed in the inner face of the meetdurable, highly efficient and reliable in use, coming rail 5 and Secured illeleO by SCI'eWS llpaet and which may be manufactured ai; 10W The plate I0 has formed therein an opening I2 cost, which is aligned with the bore 'I of the barrel 6 A11 of the foregoing and stili further objects and into which anees I3 extend, said flanges 20 and advantages of the invention will become ClOSing the inner ends 0f the gIOOVeS 9.

Projecting from the head 24 is a outer end portion of the plug, taken substanpin 25 which is engageable in the sleeve I4. tially on the line Il-II oi Fig. 9. It is thought that the manner of using the lock 55 'i will be readily apparent from a consideration of the foregoing. As hereinbefore stated, when the doors 2 and 3 of the show case I are in closed position, the barrel 6 and the sleeve I 4 are aligned. To retract the tumblers I 9, the key 2U is inserted in the cylinder Il of the plug I 6. The plug I6,V

using the key 20 as a handle, is then inserted in the barrel 6 in such a position that the segmental head 24 thereon will pass between the anges I3 and enter the enlarged portion I5 of the sleeve I4, the pin 25 entering said sleeve I4. The plug I6 is then rotated to the position shown in Fig. 3

of the drawing to prevent withdrawal of the segmental head 24 between the ilangesI I3 and bring'v the tumblers I9 into registry with the grooves 9. The key 20 is then removed from the plug I6 and the tumblers IS engage in the grooves 9 for securing said plug against rotation in the barrel 6. It will thus be seen that the plug I6 is secured against both rotary and longitudinal movement in the barrel 6. With the pin 25 engaged in the sleeve I4 the doors 2 and 3 are, of course, locked together. The foregoing operation is substantially reversed to remove the plug I'I for unlocking the doors 2 and 3. The latch or detent 2I secures the,key 2U in the cylinder Il sulciently to permit said key to be used as a handle for withdrawing the plug I6 from the barrel 6.

It is believed that the many advantages of a.

lock constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:-

A lock for a pair of sliding doors, comprising a plate secured on one of said doors, a barrel xed on said plate and extending through said one door, the plate having an opening therein aligned with the bore of the barrel, said bore of the barrel having longitudinal grooves therein, diametrically opposite flanges in the opening in the plate at one end of the grooves, a removable plugiinsertable in the barrel and including a cylinder, a neck on one end of said cylinder, a substantially segmental head on said neck adapted to pass between the flanges and engageable therebehind upon rotation of the cylinder for preventing withdrawal of said cylinder from the barrel, key operated tumblers mounted in the cylinder and engageable in the grooves for securing said cylinder against rotation in the barrel, and a pin projecting from the head and engageable in the other door for securing the doors together.
