BYRON PHELPS, OF SEATTLE, WASHINGTON.

LOCK.

SPECIFICATION forming part of Letters Patent No. 722,621, dated March 10, 1903.

Application filed September 23, 1901. Serial No. 761312. (No model.)

T0 at whom it may concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, inthe county of King and State of Washiugton,have invented a new and useful Look, of which the following is a specification.

My invention relates to looks, and particularly to a lock having a frame which carries all of the mechanism and which is adapted to be inserted in a notch in the stile of a door.

Particularly it relates to improvements in the mechanism for locking the outer knob from the face of the lock and in providing a simple and elfective device for holding the spindle in place.

Figure l is a plan view. Fig. 2 is an end View of a portion of the lock, partly in section. Fig. 3 is a view of the face, on a reduced scale. Figs. 4. 5, 6, 7, and 8 modetails.

A is a frame. B B are extensions therefrom in the form of sleeves, which provide suitable bearings for an inner spindle O and an outer spindle 0. Attached to spindle O is an inner knob D, while attached to spindle C is an outer knob D.

E is-a latch-bolt pivotally secured to the frame A.

F is a yoke one end of which is connected with the latch-bolt E, while its other end straddles the inner ends of the spindles O O. The end of spindle C is notched, and fitted therein is a roll-back G. (See Fig. 5.) The inner end of spindle O is likewise notched and carries a roll-back G.

The outer knob D is hollow and houses a key mechanism H. This key mechanism may be of the well-known pin-tumbler type and will not be particularly described.

J is a key-rod passing through the center of spindle C, one end being attached to the key mechanism, while its other end is fitted to a square hole in roll-back G. The rollback G has a central opening sufficiently large to allow rodJ to turn freely. When either spindle is rotated, its attached rollback bearsagainst and moves the yoke F, thereby retracting the latch-bolt E.

K is a spring for returning and holding the latch-bolt E in its extended position.

The spindle C has a hole L near one end.

M is a pin slidably mounted in the frame A and adapted to enter the hole L, and thus lock the spindle C from rotation.

N is a finger-lever pivoted to the frame A and lying in an opening in the face of the frame.

0 is a strap connecting the finger-lever N and the pin M.

.When it is desired to lock the outer knob, the finger or thumb is pressed against the flush end of the lever N, which rocks the same, thereby moving the strap 0 and pushing the pin M into the hole L. The parts then take the position shown in dotted lines in Fig. 1. The inner knob D is free to be turned by any one on the inside of the door, the outer knob being locked obviously.

In order to retract the latch-ebolt-from-the outside, a key must be inserted in the mecheffii'sTrTHand then turned. The roll-back G being rocked by the rotation of rod J, movement is imparted to yoke F and the latch bolt E retract-ed I P is a flat spring which takes into notches R R in the strap 0 and prevents the pin from being jarred from position.

The spindle O has a segmental slot near one end, as shown.

T is a pin one end of which is flattened, as shown in Fig. 7, and is carried in the frame A, the flattened portion projecting into the slot and its flat face bearing against the innor edge of the slot, thus holding the spindle C in longitudinal position. The opposite spindle 0 has a similar slot S and pin T.

One method of holding the pins T T, I have shown in Fig. 8.

U U are light springs which may be fastened to the frame, their free ends lying in notches in pins T T. This construction allows of the ready removal of the spindles and knobs. A further advantage is that should a pin or slot become worn a new pin may be fitted to take up the wear.

It is obvious that many changes might be made in the construction herein shown without departing from the spirit ofthe invention. For instance, the lever N might lie inside the frame and have a push-button for each end extend through and lie fiush'with the face. Other changes will readily sug- ICO gest themselves to one skilled in the art, and Ido not, therefore, li-mit myself to this specific construction.

What I claim is 1. In a look, a frame, a latch-bolt, a spindle, aconnection between said spindle and said latch-bolt, a finger-lever in the face of the said frame and a connection from said lever to said spindle, said connection being in detachable engagement with said spindle.

2. A frame, a latch-bolt, a spindle, a connection between said spindle and said latchbolt, a finger-lever pivoted in the face of said frame, a slidable pin adjacent said spindle, a strap connecting said lever and said pin, and means carried by said spindle which cooperate with said pin to hold said spindle from rotation.

3. A frame, a latch-bolt, an outer and an inner spindle, means connecting said outer spindle with said latch-bolt, means connecting said inner spindle with said latch-bolt, a finger-lever in the face of said frame, a connection from said lever to said outer spindle, key operated means passing through said outer spindle and engaging with said secondnamed means whereby said latch may be operated by said key-operated means.

4. A frame, a latch-bolt, an outer and an inner spindle, means connecting said outer spindle with said latch, means connecting said inner spindle with said latch, a fingerlever in the face of said frame, a'slidable pin adjacent said outer spindle, a strap connecting said lever and said pin, means carried by said outer spindle which cooperate with said pin to hold said outer spindle from rotation, and key operated means passing through said outer spindle and engaging with said second named means, whereby said latch may be operated by said key-operated means.

5. A frame, a spindle having a transverse slot therein, a pin carried by said frame and projecting into said slot, said pin having one bearing-face lying against one edge of said slot to hold said spindle from longitudinal play, and a shoulder on said pin forming another bearing-face which rests upon the outer surface of said spindle, to hold said spindle from lateral vibration. I

6. A frame, a spindle having a transverse slot therein, a pin removably carried by said frame and projecting into said slot, said pin having one bearing-face lying against one edge of said slot to hold said spindle from longitudinal play, and a shoulder on said pin forming another bearing -face which rests upon the outer surface of said spindle, to hold said spindle from lateral vibration.

7. A frame, a spindle having a segmental slot therein, a pin removably carried by said frame and projecting into said slot, and a spring carried by said frame and bearing against said pin.

8. A frame, a spindle having a segmental slot therein, a pin removably carried by said frame and projecting into said slot, and a spring one end of which is attached to said frame the other end engaging a notch in said in. p 9. A frame, alatch-bolt and latch mechanism for operating said latch-bolt, a fingerlever in the face of said frame, said fingerlever having two exposed faces, the plane of one face being inclined to the plane of the other face, and means connected to said finger-lever, movable into engagement with said latch mechanism.
