will bring the tubes to a break joint relation. n

It is the object of my present invention to so arrange such a lock as to permit of operation of a latching element by means of a rotary key. As incidental objects are theV provision of an economical structure formed of pressed steel or brass parts which can be readily assembled, and are to a large degree resistant to tampering.

my invention, but it will be understood that there are numerous ways in which the principles illustrated in my drawings, and in detail described, can be applied inthe construction of locks. In theory the principle of construction isv to employ an outer shell and inner shell in which is contained a revolving ele- -ment that carries a suitable projection that will operate the lock. Within this revolving element is an eccentric member containing one of the sets of tubular plungers. This member is held against rotation however by the shell structure of the device sothat it will only slide. The shell structure also acts as a stop for the rotation of the revolving element.

In another chamber in the revolving element is a set of plungers or tumblers,`cooperating with the eccentrically arranged set atV the two ends of movement of the lock, but oft center with the eccentrically arranged set at other times.

The key is applied to the second set of tumblers bringing out of break joint relation with the eccentric set, and the nt of the key into the revolving element, results in the imparting of revolution thereto.

As a result the key is universal to the eX- tent that it can be made symmetrical and be inserted with either side up, when locking or unlocking whatever latch element is being employed. v

It is a mere shift of parts to have both tumbler arrangements eccentric, to the lock I have illustrated but one embodiment of` 1927. Serial No. 199,600.

casing, and to use a key which is not symmetrical.

Also the revolving member can be made differently, and the mode of operation essen-` tially as just above described, maintained.

I accomplish my invention by that certain construction and arrangement of parts to be hereinafter more 'specifically pointed out and claimed. v y

In the drawings:

Fig. 1 is a central longitudinal section taken through the illustrated form of my lock showing it in locked position.

Fig. 2 is a like view showing the lock in the process of being revolved. 65 Fig. 3 is an inner end elevation of the lock n in the position shown in Fig. l. Y

Fig. 4t is a like view to Fig. 3 showing the lock in the condition illustrated in Fig. 2.

Fig. 5 is an end elevation of the outer face ofthe lock.

Fig. 5a is a view of a key.

The lock as illustrated is formed with an outer shellvl, which has the key hole plate 2 therein, the key holek 5 being circular with two branch slots extending therefrom. Within this outer shell, which is of pressed steel, is the inner bushing or plug 3. The shell l is closed at the inner face as at 4;, and the inner member 3 is closed, acts as a sleeve for the revoluble member. This plug 3 with the parts contained therein, is properly located withinthe shell, and the edge 6 of the shell is spun over the key hole plate, the fit and turning in of the edge over the key hole plate serving to hold the inner shell rigidly in place.

Within the shell and bushing or plug is the revolving member 7, which has an eccentric bore 8j, and a concentric bore 9. A key hole guard plate as at l0, may be set inside of the dished key hole plate.

The face tof the shell is formed with a semi-circular slot ll,.through which projects a pin l2 that is on the revolving member. The slot thus defines the limit of movement of the revolving member, and the pin is used to operate whatever latch is desired.

The face 4 of the shell also has a slot 13 therein, which acts to guide and maintain the position of the eccentric tumbler member. This member is formed with an oval outer shape as indicated at 14, within which is a' the-hole. The body 14 has a rib 17 thereon which lies'within the slot 13 in the shell.

The member 14 lies within the bore 8 which is of a size to fit its lengthwisel dimension and the tubular tumblers when normally in position will project into the circular central bore 9 of the revolving member@l ,(Fig.4 l), from the member 14.

Also locatedwithin.thebore9, which projects to theouter face of the revolving member,` arethematching set yot tubular tumblersiwln i The-bore` 9.,h,as two slots 19 in its outer portion'fwhich engages the sides of the key, indieatedjbydottedlinesat 20 in Fig. 2. I

As now, vdescrifbefd the Q lockv is operated as follows, beginning with the parts as shown in,V Figs. 1 and 3. The key is inserted through the key hole slot (Fig. 5) with which the slotin the ykeyhole guard` plate isl aligned,v and is pressed inwardly sufficiently to cause the tumblers 18,., to pressinwardly on the tuniblers 15a, until a line of cleavage is establis'hedljandl thebrealfjoint relation oi' the tumblrs is overcome. The key will when insertedrfind itsside edges within :the grooves withinthebore l9 of the revolving member,

f andwlientlie key has been pressed inwardly suiiicientlylto break the locked tumbler arrangement, it can then be revolved to turn the revolving member.,

Thelact of imparting the thrusting movementgwilly bev toizforce all of the plungers in the eccentric'al member within the confines of said member, sothat as the revolving member startsiteA move they will feed across the inner 1face'oifI the bore 9andv the thrust pressure on the `key neednot be maintained because theitumble'rs. will be 4out of line with the bore 9,

Als`the revolving memberI moves the eccentricmember will stay in the same plane but will slide'as to the ridge thereon, lengthwise of the slotin the inner shell. rAt the end of one 'fourth revolution of the key, the ridge willbe as far down in the slot as it will go, as shown in Fig.' 4, and it will then rise again, the `point being that the eccentric casing, at the endof the locking operation will be back in its exact starting position, i. e. the end of a half revolution of the key.

VVhen'thfrevolving memberis moved in opening directionJ as far as itwill go, the key may be removed, and theV lock will stay open until an insertion off the key, and areversal of the moveinentofopening, Upon the withdrawal of thekey the tumbleijsv will snap back into breakjoint 'relation'` inj'both open and closed po's'iti'on. i
