To alliuwm, it may concern:

Be it known that I, JOHN CLEMENT, a citizen of the United States, residing at Baraboo, l in the county of Sauk and State of Wisconsin; have invented certain new and useful `1inpro vements in Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'` others skilled in the art to which it apperj tains to make and use the same.

This invention relates to improvements inl locks, and especially to that class of locks disconnected therefrom.

My invention has for its objects to provide;

a novel means for connecting the handle or knob operatively with the bolt from a vkey or; device on the inside of the door and by a de-y tachable key adapted to be used from the out-j side of the door, to provide a novel guard to,` prevent the operation of the bolt except byv an authorized key, to provide a novel catch.' or device for connecting the knob-spindle or` shaft to the bolt, to so construct the lock that the minimum number of parts only are nec-v essary, so that the lock will occupy the least possible space, and'to generallyimprove and p catch Eis byits spring F normally forced-outsimplify the lock.

`With such and other objects in view the invention is embodied in the parts and the arrangement and combinations of parts herein-l after described, and particularly set forth in; A

partipular construction which for the sake of illustration 1 have therein delineated.

In said drawings, Figure 1 is a vertical lon-v gitudinal sectional view of the lock, showing Fig. 2 is a my invention applied thereto. horizontal sectional view showing parts 1n elevation. Fig. El is a transverse sectional shaft.

Fig. G is a. perspective view of the key-guard removed from Fig. 7 is an end elevation Fig. 8 is a plan view showing the guard with the key and its relation to the catch removed from the spindle. Fig. 9 is a perspective View of the key.

Referring to the drawings, wherein like reference characters refer to like parts throughout the several views, A indicates a lock-casing, Athe lock in the present instance being a mortise-lock, B a sliding bolt therein, and-C a .barrel or sleeve mounted in bearings c 4in the lock-casing and provided with operating-arms c', adapted when rotated in either direction to engage projections or lugs b on the bolt to retractthe same.

The details and novel parts of the lock will be hereinafter described.

Passing through the sleeve or barrel C and freely rotatable therein is a knob shaft or cylinder D, which, as shown, is tubular in form and contains the operating parts of the catch (indicated at E) for locking the shaft D and barrel C together, which catch projects through an opening e in the knob-spindle D, as shown, and is secured to a spring F, secured, as by a pinf, from longitudinal or rotary movement within the spindle D. The

ward and when brought in register by a turning of the knob-spindle with one of the holes or notches c2 in the barrel or sleeve C is forced by the spring into said hole or notch, thereby C,when the barrel can be rotated by the knobshaft to retract the bolt. The barrel shown has four such notches c2, two on one side and two on the other side thereof, so that the knob-shaft can be inserted in the barrel and cooperate therewith from either side of the lock.

G indicates an operator for the latch or catch E on the inside of the door, and consists in the present instance of a tube rotatably mounted within the spindle D and pro- IOO jecting at its endg sufficiently far beyond the knob or handle (indicated at D) to enable it to be grasped and rotated. This tube G has at g g at diametrically opposite points therein notches or slots through which the pin f passes. These notches are of su fiicient length to permit a partial rotation of the shaft or tube G, and each slot is provided at one end thereof with a longitudinal offset or enlargement of the slot g2, permitting a slight longitudinal movement ofthe tube G for a purpose hereinafter specified. At g the tube G is cut away to provide space for the free movement of the spring F. g3 indicates a cam or inclined lug on said shaft or tube G and adapted iu the rotation of said tube in one direction-to the right, in this instance-to engage a projection or lugf2 on the spring F and retract the latter, drawing the catch E out of the notches in the barrel C and into the hole c in the knob-shaft to permit a free rotation of the latter in the barrel. The operator just described for the catch E, it will be observed, is not intended for removal from the shaft, but is intended for the inside operator andremains in place at all times.

Within the knob-shaft at the outer end or end opposite the operator G is at guard-plug H, which at its inner end is ot' substantially the diameter of the bore of the knob-shaft and is at its outer end and for the greater portion of its length of reduced diameter, leaving an annular space between the plug and the inner wall of the knob-shaft, as indicated at h, for the introduction of an annular key or operating-sleeve, (indicated at I.) .The guard-plug H is held fixedly in the knob-shaft in any suitable manner,as by a pin 71, passing through the large end thereof and through the knob-shaft. The guard-plug at its enlarged end is cut away at h2 or slotted to receive and permit the rotation therein of a longitudinally-extending finger h3 on the operator G. This finger h3 is adapted to be engaged by a suitable part, as i' on the key I, to rotate the operator G after the latter has been turned to retract the catch E from the barrel C, so that after the knob-shaft has been disconnected from the barrel on the inside of the door by rotation of the operator to the right the engagement of the key with the finger h3 will upon turning the key I to the left turn said operator G to the left and permit the spring F to throw the catch into one of the notches in the barrel and lock the knob-shaft to the same, thereby permitting the throwing or retraction of the bolt by the operation of the outside knob or handle, (indicated at CZ'.) Any suitable arrangement of guards to prevent the introduction of an unauthorized key may be provided, that shown being very efficient and comprising a projection h4 on the guard-plug opposite the end of the slot h2 and a sufficient distance therefrom to permit the introduction and rotation of the part t' of the key. A second projection h5,

out of alinement with the projection h4, is also provided, these two projections requiring a key of novel construction, such as indicated, to be used. The key shown is provided with the longitudinal slot 2, having the lateral olfset portions 'lf3 and i4 to permit of the key being turned after it has been inserted. h is a lug on the guard-plug, adapted to engage the rear end of the part on the key to prevent rotation in the opposite direction. The construction of the guard and key,it will be observed,constitutes a very efficient means for preventing the insertion of an implement other than the properly-fashioned key to engage and operate the finger 71.3. It will beobserved that by means of the longitudinal extension g of the slots g in the operator Gthe latter can be moved longitudinally to bring the finger h3 o ut of the path of the part 'L' of the key, and thus effectually prevent the operation of the catch E from the outside by the key or other means.

The knobs or handles d d may be secured to the knob-shaft in any desirable or suitable manner, they being shown screwed onto the ends of the shaft and held from rotation thereon by means of keys d2 d3.

My lock proper is also of novel construction in the following particulars: The bolt B is practically of the same width as the casing A, but is sufficiently shorter than the casing to permit of its sliding longitudinally therein. The bolt is reduced in thickness, as indicated atb', for the provision of space for the operating-sprin g, (indicated at K.) This spring is heldin place between the wall b2 of the bolt and a bar L, movably supported on the reduced portion of the bolt and prevented from backward movement thereon beyond a certain point by the lugs or projections b4. On one part of the lock-casing A, which is shown as being made in two parts a and a', are lugs or projections a2, adapted when the parts of the casing are together to engage behind the bar L at the sides of the lugs or projections b4 and prevent the rearward movement of the bar L when the bolt is retracted, thereby placing the spring K under tension, which will tend to force the bolt outward into engagement with the bolt-strike. It will thus be observed that the lock is constructed in a very compact and simple manner and that when the parts of the lock-casing are separated the spring is relieved from tension, thus avoiding the usual objections to a lock in -which the springs are held between a part of the casing and the bolt and are liable when the casing is opened to spring out of place, thereby causing great annoyance and trouble in replacing the spring.

M indicates an edge plate suitably fashioned to engage the end of the lock-casing and provided with suitable screw-openings mm for the securing-screw. The plate M,

as shown, is detached from the casing A. As will be seen from the drawings, the bolt is IOO IIO

IIS

made with parallel sides, andthe lock-strike' (indicated at N) is provided with a suitable projecting inclined portion n to be engaged by the bolt in the closing of the door. This, however, is immaterial, as the bolt can be, as is common, provided with a beveled face to engage the straight lock-strike.

In order that the operating-key and operator G may not project so far beyond the operating handles or knobs to disligure the same and at the same time to provide sufficient space for grasping and operating the key and operator, I have shown each knob provided with a concavity or cup-shaped recess, (indicated at d21 and dil, respectively.) y

From the foregoing description it is believed the operation of the lock will be readily understood, it simply remaining to say that when the catch E is by its spring thrown out into engagemant with th'e barrel the operator simply turns the operator G to the right, retracting the catch E by the engagement of the cam-lug on the operator with the projection f2 on the spring F, and that after the catch has been so retracted the operator G can be turned to the left to permit the spring F to again throw the catch into engagement with the barrel by the insertion of the key I and the turning thereof to the left, when the part t' of the key will engage the finger 71,3 of the operator and turn the latter.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-,
