LOCK.

SPECIFICATION forming part of Letters Patent No. 626,343, dated June 6, 1899.

Application filed December 29, 1898.. Serial No. 700,588. (No model.)

To all whom it may concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, county of King, State of Washington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to looks; and my ob ject is to improve the construction of the same.

In the accompanying drawings, showing the preferred embodimentof myinvention,Figure 1 shows a plan view, parts being in section, of my lock applied to the stile of a door. Fig. 2 showsahorizontalsectionalviewthereof. Fig. 3 shows a vertical sectional view on the line X X of Fig. 2 looking as the arrows fly. Fig. 4 shows the broad roll-back. Figs. 5 and 6 show details of the outer knob and spindle. Fig. 7 shows the frame of the lock in plan view. Fig. 8 shows a vertical section on the line' Y Y of Fig. 2 looking as the arrows fly. Fig. 9 shows a detail of the inside knob and spindle. Fig. 10 shows the locking-rod. Fig. 11 shows the connecting-rod between the lock in the outside knob and'the narrow roll-back. Fig. 12 shows the narrow roll'back. Fig. 13 shows a side elevation of the outer knob, the pintumbler lock therein being shown in dotted lines.

This embodiment of my invention is intended to be inserted in a notch in the stile of the door, following out the general lines in this respect of my former application, filed March 10, 1897, renewed December 5, 1898, Serial No. 698,371.

In regard to the present embodiment of my invention it will be observed that the knobs and spindles are offset. It often happens that the stile of a door is so narrow that a deep notch cannot be cut therein without materially weakening the same; but yet it is disadvantageous to bring the knobs very close to the edge of the door, because when the door is shut the outside knob would pass so close to the jamb that a persons hand on the knob would probably be caught between the knob and the jamb and injured. This objection is not present with respect to the inner knob, because said knob does not pass said jamb at any time. To give greater clearance between the knob and the jamb, and thereby avoid the of two parts, as shown.

danger of thus injuring the hand, I offset the outside knob, as shown.

Referring to the drawings, A represents a frame, preferably formed integral and having spindle-bearings B O and projecting faceplate a. Over these spindle bearings are slipped side plates or escutcheons Z) c, relatively adjustable toward each otherfor instance, by the screw b -so as to clasp the sides of the stile of the door, as set forth in my said former application.

D is a latch-bolt working in an aperture in the face-plate a and pivoted at (Z.

E is a shoe having a yoke e pivotally connected to the latch D by a connection d. This connection has a lug (1 between which and a lug a on the frame is a spiral spring a tending to press this latch connection and shoe outward, as shown in Figs. 1 and 2.

B is a knob, preferably having a hollow spindle attached to the inner side of the head thereof and rotatably supported in the spindle-bearing B. This knob may be formed To the inner end of this spindle b is fixed, by dowel-pins b, a roll-back b which has lugs b thereon which contact with lugs e on shoe E to retract the same, and consequently the bolt D. F is a second shoe narrower than said first shoe E, lying alongside the same and havinga slot f therein, into which projects a lo g e on shoe E. Shoe F has also a hole f therein opposite a hole a in the relatively stationary frame when said shoe is in its normal position of rest. Shoe E has an elongated slot (2 therein, extending, when said shoe is at its normal position of rest, over the holes f and (1 as shown in Fig. 2.

G is a second knob, preferably formed in two parts, the part g having the spindle g and the other part 9 forming a cap suitably attached to said part gforinstance, by screws, as shown-and hollowed out to inclose a look, if desired. The general features of this knob and inclosed-lock construction are claimed in my former application, Serial No. 699,891, filed DecemberfZl, 1898. This spindle g has a tongue on the end thereof, as shown in Fig. 6, over which fits a broad-face rollback II, which has a slot h and shoulders 72/ h. This roll-back may be fastened to the spinpreferably of the familiar pin-tumbler kind,

in which one part K constitutes the casing and which has an inner part 7c, which is normally locked to the casing by the pin-tumblers, but which may be rotated by the insertion of a suitable key, as in said former application. The casing of this look is fixed relatively to the knob G by projections as shown, so that it will rotate with said knob, but will be always in fixed relation thereto.

The part 70, which I designate the key-bar rel, has a key-slot 70 exposed by the opening g in the cap 9 By the insertion of the key into this key-barrel the pin-tumblers will be raised and the key-barrel may be rotated relative to the casing and knob, as is usual in this class of locks. This key-barrel may carry on the end thereof a lag W, to which'is attached a rod L, (shown in detail in Fig. 11,) reduced at its inner end Z to fit the hole in roll-back M andthreaded. Over this reduced inner end is slipped a narrow roll-back M, which is held to the end of this rod by any suitable fastening means, such as a nut Z. This roll-back is fixed to this rod, is rotatable therewith, and has the usual shoulders m thereon. The roll-backs H and M prefer-ably have their shoulders in alinement and contact at the same time with the yokes e and f on the shoesEand F, as shown in Figs. 3 and 8. It will be evident that both roll-backs will normally be operated when knob G,and consequentlyspindle g, is turned, and will therefore throw back both ,of the shoes, and consequently the latch-bolt D. The wide roll-back H extends from in contact with the narrow shoe F across into contact with the wide shoe E; but the roll-back M contacts only with the wide shoe E. The broad roll-back H is firmly fixed to spindle g and act-uates shoe F, which contacts at the rear ofslotftherein with lug e on shoe E. Rotating g therefore would throw back shoe E, and consequently latch D, even if rollback M were not present, and this construction of spindle g, roll-back H, and shoe F takes most of the strain off from rod L, rollback M, key-barrel k, and the pin-tumblers k when knob G and spindle g are rotated. This prevents the relatively weaker latchoperating meansnamely, key-barrel 7c, rod L, and roll-hack M-from being strained at every rotation of knob G and spindle g, and

consequently loosened.

N is a locking-rod held inside the hollow spindle b so as to be longitudinally movable therein and is pressed inwardly by the spiral spring 11 in said spindle. The locking-rod has a pin '11 projecti-n g laterally therefrom through a slot in bearing B and a slot n in spindle 12 as shown in Figs. 1, 7, and 9. O is a rotatable finger-cam preferably held outside this spindle b and bearing 13 and against shoulder 12 on thespindle-bearing, as shown. The finger-piece has a cam-face abutting hole a in the frame.

against the pin it. By the rotation of this finger-cam the pin it, and therefore the locking-rod, may be moved outward and allowed to be moved inward by the spring a. This locking-rod has a projection n in the inner end thereof, which preferably passes into a longitudinal slot 6 in the shoe E.

It will now be evident that when knob G is turned both roll-backs will be rotated and both shoeswill be retracted. When however, the finger-cam O is rotated, the spiral spring will press the locking-rod N inward or to the right in Fig. 2 and the projection 11 will pass through the hole f in shoef and pass into the This will lock shoe F from retraction; but the shoe E may still be drawn back, because the slot 6 therein allows a movement of said shoe in spite of projection 01 When the locking-rod thus locks the shoe F, the knob G and spindle g cannot be rotated, because the shoulders h on roll-back g abut against the lugs on the yokes f of the locked shoe. This results in locking the knob from rotation. By the insertion of a key, however, into the key-barrel the same may be rotated inside ofthe knob,which would rotate the rod L and roll-back M, which in turn will retract shoe E, and consequently latch D. In this way the door may be opened, although the outside knob G is fixed and the door locked in respect to it. The inner knob B can operate the shoe E, and consequently the latch D, at any time, as said shoe is preferably not at any time locked.

It will. be obvious that many changes may be made in my construction herein shown without departing'from the spirit of my invention.
