It is known that, in combination locksof the type here shown, it hasheen necessary to have two marks the lock-from, andTthe other to serve as a'guide'when' 1 Thisnecessityhasarisen from the fact that slotted fall, must be operated in looking and unlocking from" a point wherethe slots; of the wheels may be placed point is thetop of' :thefwheels and immediately under the dog; and the mark on the dial for} this purpose has usually, forconvenience, been placed at the top IIf' it was attempted change the-combination from ventthe separate movement of the wheels.

sustaining-the dog out of the slots of the wheels while the combination is being changed.

Description of the Accompanying Drawing.

Figure 1 is a plan of the inside of the lock, the permutation-wheels being removed, and part of the disk which operates the dog-lever B broken away, sh owing the mechanism above referred to when in position not to afifect the dog,

Figure 2 is a similar view, except that the said mechanism is in position to sustain the dog.

General Description. i As there is no part of the mechanism shown in the drawing except that used for sustaining the dog, that is new, or upon which I desire to make any c1aim,it is notdeemed necessary todescribe the construction or operation of other parts of the lock, which, it is believed, is sufiiciently described in the specification attached to Letters Pat'ht No. 106,472, granted to Charles Diebold and Jacob Kienzle, dated August 16, 1870. l

In the drawing- A represents a lever, pivoted so that its upper end shall rest under the bar or lever to which. the dog is attached, so that by operating this leverA the dog shall be raised out of the gate or notches in the wheels and held up while the combination is changed.

For thepurpos'e of operating this lever A I provide acam or arm, A, which is fitted in a recess on the inner face of the outsidecase of the lock, immediately opposite the hole on the inner case of the lock, which is intended as the point of entrance for the key, by,

which the permutation-wheels are made fast and loose. When the wheels are arranged with their slots in line under the dog, which is done by the mark on the dial by which the lock is operated, the key is inserted through the appropriate hole on the inner face of the lock-case, and through the permutation-wheels,

jthe end of it passing into the hole shown in A, it is turned half a circle to the right, sufiicient to loosen the wheels, wh'ich will, by the operation of lever A,

cause in the permutation-wheels the key requires to be turned half a circle in order that the wheels may move freely while the change is being made; but it is self-evident that this lever may he so adjusted as to raise the dog by turning the cam any portion of a circle that will be sufiicient to loosen the permutationwheels.

It is also evident that one lever, or three or more levers, could be substituted in place of the one shown, without varying from the invention described, and that their forms might be varied indefinitely.

C laims.

I claim as my invention- 1; Thelever A and cam A, arranged to operate JACOB OBERNESSER.
