LOCK.

SPECIFICATION forming part of Letters Patent No. 297,660, dated April 29, 1884.

I Application filed October 22, 1883. (No model.)

To all w/wm it may concern/.e

Be it known that I, FREDERICK BALLIN, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Im- 5 provements in Door-Locks;` and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which forma part of this specication.

This invention relates toy certain new and useful improvements in door-locks; and the invention consists in the peculiar construction f a hollow spindle which carries the lockingtumblers, said tumblers being actuated by means of a key inserted throughthe spindle,

and in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter set forth.

Figure l is lan elevation of a rim-lock detached from the door and withspindle broken offv close above the tumblers. Fig. 2 is a secr tion of the line x y, Fig. l. Fig. 3 is a Vertical section through the lock and door on the axis of the spindle. Fig. 4'is an elevation of the spindle detached from the lock, showing the spring by which the tumblers are held in their position and to prevent accidental displacement. Fig. 4" -is a sectionV through the spindle, showing how the tumblers are held iu Fig. 5 is a longitudinal central section through tumblers adapted to be actuated from either side. Figs. 6 and 7 are views of two different keys-the keyv 6 for the tumblers shown in Fig. 5, and the key 7 for the tum- 3 5 blers shown in Fig. 3. Fig. 8 shows two crosssections on the line a o and o w, respectively, in Fig. 4, Fig. 9 is a cross-section on line r s in Fig. 4". Fig. 10 is a cross-section on line t u, Fig. 5. Fig. l1 is an end View of the Fig. 12 shows arrangement of lock-case wherein my invention is applied in the construction of a mortise-lock.

In the accompanying drawings, which form a part of this specieation, W represents the lock-case, and W the back plate thereof, which inclose the operating parts of the lock. A represents the bolt, which is kept in-Lits eX- tended position bythe spring S, as in the or- This bolt A is provided with a leg or arm, A', which operates in conjunction with the tumblers to prevent the turn ing ofthe spindle, as hereinafter described.

T represents the spindle of my lock, and is hollow its entire length, and receives upon each end a knob, K, to which they are remov- .ably secured in any convenient manner, and

adapted to turn the spindle when the latter is notlocked, as hereinafter stated.

Upon the spindle I secure the tumbler-lever B, by Ameans of which the bolt A is retracted upon the turning of the spindle. C C are the locking-tumblers, which project through a slot, a, in the spindle. The tumbler C is provided with a solid pintle, C, which fits loosely in the spindle, and has its end so formed as to register in the ,end of the key. This pintle carries a pin, C, which ts loosely in the hollow pintle CW of the tumbler C'. The ends of this pin and pintle are likewise made to register conjointly with the key. s

In order to keepA the locking-tumblers in their adjusted positions and to prevent their accidental displacement, I place a spring, O, in a longitudinal channel on the outer face of the spindle, and between it and the tumbler B. 1 The ends of this spring are bent inwardly and project through holes in the pintle, so as to engage with yrecesses or notches in the respective pintles of the tumblers.

In the end of each knob I secure aislotted disk, U, through which the key is inserted in the spindle.

In the construction above described, by inserting the key from the inside, (or lock side fand in consequence both pintles and theirv respective tumblers will in turning the key be partially rotated, bringing the free ends ofthe tumblers in rear of the arm orleg A'l ofthe bolt, being held to suchV position by the spring'O, and thus prevent the turning of the spindle and a retraction of the bolt. `hen so locked, it cannot be unlocked from the outside, as the key inserted from that end operatesV but one pintle and tumbler,leavin g the other stillin its locked position; but, on the other hand, if locked from the outside, it can be unlocked from the inside. y

If desired, but one tumbler may be used,

IOO

each end of its pintle being adapted to register with the key; or both tumblers may be so formed as to be operated from either side,one form of so doing being shown in Fig. 5, wherein the pintle of the tumbler C is provided with a leg or spur, which projects back and registers,in connection with the corresponding end of the pintlc C, with the key.

To adapt this construction toa mortise-lock provision must be madefor insert-ing the spindle and tumblers, .after the lock has been secured to place, in the door; and this I accomplish by cutting away a portion of the back plate of the lock and making a proper opening in the corresponding side of the door, through which the tumblers and spindle may be inserted, being retained in place by a cap, I, as shown in Fig. I2, while the opening in the door is covered by the rose.

In Fig. I I show a spring, Y, for retaining the locking-tumblers in their adjusted posi'- tions, which may be used instead of the spring O, if desired.

To insert the pintles, with their tumblers, into the spindle of the lock, I cut away aportion of the spindle,leaving an oriice sufficiently large through which to insert the pintles, with their tumblers projecting downward. After this has been done, I solder the piece again to place, leaving the s lot hereinbefore described, through which the tumblers project and have an easy movement, to be operated by the key; and in this construction I avoid al1 possible danger of the pintles and tumblers becoming lost or detached.

In Fig. 3 I show guards It as projecting into the spindle upon the outside ofthe door, which is designed to register with the edges of the iat key employed, and thus give greater security against the picking of the lock by the insertion of a wrong key, even should such key register with the pintles upon its end.

rlhe method of securing the knobs, particularly in mortise-loeks, that I prefer is to form the channel in which the spring O rests the entire length of the spindle, the knobs being secured to the roses, as shown in Fig. 3, so that they can turn readily without imparting any movement orstrain upon the roses, while upon the inside of the shanks of the knobs I form o1' rigidly secure a feather, which is designed to fit into this recess, the knob being held to place upon the spindle merely by the screws which secure it to the door; hence in pulling upon the knob to forcibly open the door suoli strain is brought entirely upon the door and rose without bringing any strain whatever upon the spindle and the operating parts of the lock.

I am aware of the Patent No. 258,986, and make no claim to the construction showll therein.

Vhat I claim as my invention is- 1. In a lock provided with a hollow spindle, two tumblers, the pintles of which are inelosed within said spindle, and constructed and arranged substantially as specified,where by the insertion of a key into one end of said spindle actuates both of said tumblers, while by inserting the same in the other or opposite end only one of such tuinblers can be operated, substantially as and for the purpose set forth.

2. In a lock, and in combination with the hollow spindle thereof, the tumblers C C, the latter being provided with a solid pintle upon one side anda pin upon the other, said pin passing through the hollow pintle of the tumbler C', substantially as set forth.

3. In combination with the two tumblers C C, provided with pintles having depressions or indentations, and hollow spindle T, having openings coincident with said depressions in said pintles, and provided with a longitudinal groove on its outer face, the spring O, seated in said groove, with its ends projecting through said openings in the spindle and engaging with said pintles to prevent their displacement, as set forth.

4. In combination with the hollow spindle T, having a longitudinal groove and openings, as described, and tumblers C C, provided with pintles having depressions coincident with said openings, the spring O, seated in the said groove and held therein by the tuinbler sleeved 011 said spindle, the ends of said spring being in engagement with the said pintles, substantially as and for the purpose specified.
