SPECIFICATION forming part of Letters Patent No. 769,768, dated September 13, 1904. Application filed December 4, 1903. erial No. 183,818. (No model.)

To all whom it may concern:

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, King "county, Washington, have invented certain description.

My invention relates to locks and latches,

'and particularly to one which combines the features of a unit and a mortise lock.

Those locks which are assembled preparatory to being applied to a door and in which the lock mechanism need not be taken apart in making said application and which obviate the necessity of forming a mortise in the unitlocks. The usual way of'applying aunit-lock to a door is to saw a notch out of the stile thereof and set the lock in place bodily. A mortise-lock is not actually assembled until applied to a door. The lock mechanism is carried in a case which is introduced into a mortise formed in the edge of the door. Each type has its advantages. By my present invention I combine these advantages in one structure.

In the drawings, Figure l is a perspective view of a portion of a door, showing my lock partly in place and illustrating the method of cutting out the door to receive the lock. Fig. 2 is a vertical section of a door on the line a a, Fig. 4, showing my lock in place, a portion of the lock being also shown in section Fig. 3 is a plan view of a portion of a door with my lock partially in place, those parts of the lock within the door being shown in dotted outline. Fig. A is a plan view of the lock as it appears finally in place, the door being shown in horizontal section. Fig. 5 is a vertical sectional viewof a door fitted with my lock, the parts being shown in the position indicated in Fig.

4. Fig. 6 is a view similar to Fig. 5 excepting that the night-latch is applied to lock the outer knob against rotation. Fig. 7 is aver- Fig. 8 is a detail 'view partly in section. Fig.

9 is a side elevation of the night-latch-con- V trolling device. Fig. 10 is an end elevation of the inside of the outer knob. Fig. 11 is a perspective view of a detail of construction. Fig. 12 is a detail view showing the part illustrated in Fig. 11 in place; and Fig. 13 is a perspective view of the frame of my lock,

the various operating parts of the lock being detached therefrom. In this View a portion of an escutcheon-plate is shown as attached to the frame.

1 is a door in the edge of which is formed the usual mortise such as might be provided to receive an ordinary mortise-lock case. At the rear of this mortise and registering with the same is a vertically-elongated transverse opening extending through the door.

In applying my lock instead of introducing the same after the manner of introducing a mortise-lock, which is from the outside inwardly through the mortise, the lock-frame is introduced through the transverse opening with the bolt and the associated parts poised vertically. (See Fig. 1.) When the lockframe is in the proper plane to register with the mortise, the same is rolled to the hori- Zontal position. (Shown in 2.) In this position the forward extension supporting the latch bolt or head and the parts associated therewith stands in the mortise, while the main bearing or backbone of the lock stands within the transverse opening. This opening assembled ready for use.

One of the many advantages of locks of the unit type resides in the fact that the lock mechanism may be thoroughly tested before it is applied to a door. While in some respects my new lock possesses the ear-marks of a mortise-lock, nevertheless in the above respect it possesses the advantage of the unit construction. I

2 is the tubular bearing which constitutes the backbone of the lock.

3 4: are roll-backs which are located in a recess formed in this bearing 2, which recess is sufiiciently large to enable said roll-backs to be rocked. The roll-backs 3 4 are respectively held in place by the knob-shanks 5 6, the ends of which shanks are notched to receive the same.

51 is the knob for the inside of a door.

61 is the knob for the outside of the door.

7 is a key-controlled spindle, one end of which projects into a squared opening in the hub 72 of a cylinder-lock carried by the outer knob 61.

71 is a spring preferably located within the knob 51 and pressing against the end of the spindle7 adjacent thereto. The effect of this spring 71 is to cause the spindle 7 to normally move to the right as viewed in Fig. 5.

The knob-shanks 5 6 receive their support in the tubular frame 2, and since the support for each knob-shank is a long one said knobs are prevented from becoming loose or rattling. Furthermore, by having a long bearing for each knob-shank the perfect alinement of each knob-shank is insured and the free action of the knob made certain. Each ofthe knob-shanks is held in place by means of a spring-pressed latch 8, pivoted at 81 on the frame 2. The latch 8 plays'ih a slot in said frame and is pressed by a suitable spring 9. Each latch 8 may have a rounded bearing-face arranged to project into an annular groove in its respective knob-shank to prevent the unintentional removal or disengagement of the knob. The side of each latch 8 adjacent to the entrance for the knob-shank may be beveled, as best seen in Fig. 8, so that while it will normally project into the path of the end of the shank it may be pressed back when said shank encounters it. In Fig. 2 the latch 8 is shown in its normal operative position and holding the knob-shank 5 in place. In Fig. 8 the latch is retracted and freed from the knob-shank, as it would appear were it lifted manually against the action of the spring 9. One convenient means for providing a spring-pressure against the rear of both latches 8 8 may comprise a single spring-steel strip 9, held in place intermediate in its length by means of a cotter-pin 91. To remove either knob. it is merely necessary to lift the free end of its respective latch 8 until it is withdrawn from the annular groove in said knob-shank, whereupon the knob may be withdrawn.

The key-controlled spindle 7 passes through both of the roll-backs 3 and 4, and both of said roll-backs are rotatable independently thereof. The roll-back 41 is, however, suitably held on the spindle 7 against independent longitudinal movement for the purpose hereinafter described. The spindle 7 is locked against independent rotation relatively to knob-shank 5 by means of a removable pin 73 standing in a suitable hole in said spindle 7 and projecting outwardly through a longitudinal slot in said spindle 5. This pin projectsoutside of the knob-shank and into the path of a night-latch-controlling device 10.

7 eaves 101 is a cam-surface on said controlling device 10, against which the side of said pin 73 bears. By rotating the controlling device the pin 73 moves back and forth longitudinally of the knob-shank. (See Figs. 5 and 6.) In Fig. 5 the pin is represented as resting in a notch in the high part of the cam-surface 101, and the spindle 7 is moved to the left. When the controllingdevice 10 is rotated, the spindle 7 under the influence of spring 71 is shifted to the right and into the position indicated in Fig. 6. ing means for shifting the spindle is to cause the roll-back 41 to shift from the position shown in Fig. 5 to that shown in Fig. 6, or vice versa. In Fig. 4 said roll-back is shown in a position wherein the latch-bolt 11 may be retracted by the turning of either knob 51 or 61. When, however, the roll-back 1 is shifted to the position indicated in Fig. 6, the same enters a notch 24 in the stationary frame 2 and is locked against rotation. This looking of the roll-back 4 prevents the rotation of the outside knob 61, and hence prevents any one from opening the door from outside excepting by the use of a key adapted to fit the cylinder-lock in the outer knob. With such a key the spindle 7 may be rotated, which in turn will rotate the knob-shank 5and rollback 3 through the medium of pin 73. The rotation of the roll-back 3 will of course retract the latch-bolt.

The connections between theroll backs 3 1 and the latch-bolt 11 comprise a latch-slide 12, which preferably makes a telescopic connection with the latch-bolt. The latch-slide 12 has hooked extensions 123 123, which project back of said roll-backs, so that when either of the latter are rocked the latch-slide will be retracted.

111 is a stem on the bolt 11. This stem passes through a tubular portion 121 of the latch-slide 12 and is prevented from withdrawal by means of a pin 112, Aspring 113 is located within the tube 121 and presses against a shouldered abutment on the stem 111 at one end and at its other end against the inner end of the tube 121. This spring causes said telescopic parts to assume nor-' mally the position shown in Fig. 1. The latchslide and the parts associated therewith are guided by a forward extension 21 on frame 2.

211 is an enlarged bearing on the extension 21, which may fit between shoulders 22 on the tubular frame 2 or escutcheon-plate 15, which latter is secured to the frame 2. A screw 23 may be employed to pass through said shoulders 22 and the bearing 211 to hold the said parts together.

212 is a bearing which may be turned up of the tubular portion 121 of the latch-slide which may be pressed toward said bearing by The purpose of rovid- IIO means of a spring 122, one end of which takes up against an abutment 213 on the extension 21.

To prevent the end of the spring becoming jammed between the abutment 213 and the slide and to prevent the end of the spring from getting under said abutment, I have provided a retaining device in the form of a U-shaped device 214, having upturned spurs 215. This U-shaped retaining device is placed in the position (see Fig. 12) on the abutment 213, the end of the spring 122 being temporarily held forward up. When the retaining device 214 is in place, the end of the spring is allowed to move down, care being taken to have the spurs 215 project within the spring. It will now be seen that when the parts are thus assembled the spring holds the device 214 in place and the abutment 213, plus the retaining device 214, forms a round guide-passage for the tubular portion 121 of the slide 12, and the spring 122 is held against dislodg ment.

The extreme ends 216 of the frame extension 21 may be upturned and provided with holes to receive screws by means of which the face-plate 13 may be held in place. The bolt 11 may project through the usual opening inthe faceplate 13. The roll-back 4 while mounted so as to be independently rotatable of the key controlled spindle 7 is nevertheless secured thereon (by any suitable means) against independent longitudinal movement for example, by a blocking device on each sideso that the same may be shifted from the position indicated in Fig. 5 to that indicated in Fig. 6, and vice versa, for the reason above stated.

14 and 15 are escutcheon-plates. The plate 15 is preferably fixedly secured to the frame 2.

The plate 14 is preferably slidable on the tubular portion of the frame 2 and may be adjusted to and fro tothe thickness of the door to which the lock is to be applied. When this is done, the plates 14 and 15 may be secured together by means of screws 141 141. The escutcheonplates may also be secured to the door 1 by means of ordinary wood-screws. (Not necessary to show.) Should it be desired to have more back-set to the knobs relatively to the edge of the door, this may be very easily accomplished by merely substituting a longer forward extension 21 and a latch-bolt having a longer stem 111. None of the other parts of the mechanism may be altered in any way, The spring 113 acts as an easy spring to permit the bolt 11 to recede independently of the latchslidefor example, when the door is being closed. The spring 122 is usually heavier than the spring 113, since its function is to re turn the roll-backs, knobs, and latch-slide to their normal position.

To apply my lock to a door, the knob 51, controller 10, and escutcheon-plate 14 are removed. This removal is effected by manever, the parts are in the position indicated in Fig. 3, the pin 73 may be readily removed,

whereupon the knob-shank 5 is free to be withdrawn entirely, after which the controlling device 10 and escutcheon-plate 14 may be removed. The lock may then be inserted through the transverse opening in the door and then rolled into the final position, whereupon said escutcheon-plate 14, controlling device 10, and knob 51 may be replaced. The face -plate 13 of course is applied finally. Either knob 51 or 61 may be inserted into its bearing in frame 2 without the necessity of manually operatingeither latch 8; but neither knob can bedetached until said latch is moved to the position indicated. in Fig. 8.-

The fact that the latch-stem is not held positively against rotation in the tubular portion 121 of the latch-slide permits the bolt to accommodate itself exactly to the hole in the face-place through which it passes, and this obviates any undue binding which might tend to impede its free action. By arranging the latch-stem 111 so that it acts telescopically with the latch-slide 12 a straight-line motion is attained, also assisting in the free action of the parts. By forming the extension 21 of sheet metal economies in manufacture-may be attained. When the. parts are assembled, it will be observed that the wood of the door is well removed from all working parts of the lock, and hence there is no danger of cramping or binding of said parts due to any warping or swelling of the door. The escutcheonplates 14 and 15 may be readily changed without in any manner modifying or changing the construction of the latch mechanism proper.

By this new method of fitting a lock to a door the mortise may be more readily formed than were the inner end of the mortise closed. The mortise necessary to receive my lock is obviously of less depth than that required for an ordinary mortise-lock.- There is no necessity of sawing into or removing any substantial portion of the stile of the door; but the same preserves the appearance usual-to a mortise-lock construction.
