Application filed October 29, 1920. Serial No. 420,446..

T 0 all whom it may concern:

Be it known that we, EUGENE Gnrsonr and EnNns'r VON Bnon, a citizen of the United States and a subject of the King of Italy, respectively, and residing in New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Looking Devices, of which the following is a specifica- 'tion.

I from the outside of the inclosure, except by the use of a key to release the bolt; but with the device nevertheless capable of per mitting the bolt to be withdrawn, from the outside of the inclosnre, by hand without a key whenever desired;

A further object of the invention is to provide a locking device having a bolt which requires a key to enable it to be withdrawn,

from the outside of the inclosure when it has been projected the full distance to looking position; the bolt being then held by a retainer against return movement; the parts of the lock being nevertheless capable of permitting the bolt to move only part of the full distance; so that, while the door can then be held shut, no key to open the door, from without the inclosure, is needed.

Another object of this invention is to provide a locking device that is comparatively the shape, size and arrangement of the various parts wlthout departlng from the nature and spirit of the invention, to the full extent indicated by the general meanings of the terms in which the claims are expressed.

On the drawings E- I Flgure l'is an inside View of a locking device according to our invention showing the bolt or latch therefor, and the parts to actuate same, in a suitable casing, presented as having the top removed to show the interlor;

Fig. 2 is a horizontal section on the line 22, and Fig. 3 a vertical section on the line 3+3 of Fig. l;

Figs. 4 and 5 are viewssimilar to Fig. 1 of aniodified form of our lock with the parts in different operative positions; and Fig. 6 is a'section on line 6-6 of Fig. 4.

The same numerals identify the same parts throughout. r '1 On Figs. 1, 2 and 3, numeral 1 indicates a suitable casing consisting of a top and four sides; the bottom of this casing being open if preferred; and the casing being adapted to be secured by screws or any suitable fastening devices to. a door or other member'2 which is to be fastened by our locking device. When the casing containing the locking device is mounted upon the 2 and 3; this top. beingoomitted from Fig. i V

1 to give a clear view of all the parts of the locking device. As will be understood the frame of the door 2 may carry a striker plate having an opening through which the end of the bolt 3, which moves out of the casing 1 through the opening 4, can enter; and when the bolt 3 enters this striker plate the door is locked and cannot be openeduntil the bolt 2 is withdrawn. As striker plates of various kinds mayv be used the illustration of the striker plate is not thought to be necessary.

The top of the bolt is provided with a longitudinal row of teeth 5, constituting a rack to engage the teeth of a pinion or member 6.

This pinion is carried by a shaft or spindle 7 that extends through the door 2 and easing 1 and carries at each extremity a knob 8. When the shaft 7 is turned by either of these knobs the bolt 2 can be moved back and forth. When the shaft 7 is made to turn the pinion 6 to withdraw the bolt en tirely into the casing 1 the door can be opened; and when the pin 6 shoots the bolt in the opposite direction as far as it is designed to go the door will be held fast and cannot be opened from the outside of the inclosure except by means of a key; because when the bolt has been projected the full distance to locking position, the front end of the bolt being as far out of the casing as it will go, a retainer 9 in the casing 1 will engage the bolt and prevent it from being moved either outward or inward until the bolt is released. This retainer is shown as mounted upon a pivot 10 in the casing 1 below the bolt 3 and the end thereof is adapted to enter a recess 11 in the side of the bolt; a spring 12 in the casing pressing the retainer 9 toward the bolt so that as soon as the recess 11 comes into registry with the end of the retainer the end of the retainer will enter this recess. Obviously, then the bolt 3 cannot be pushed back into the casing to allow the door 2 to be opened until the retainer 9 is made to disengage the bolt.

To cause the retainer to release the bolt we make use of an ordinary tumbler lock 13 which may be of any well known construction and comprises the usual cylinder which can be mounted in an opening in the door 2 so that the inner end of the cylinder of the tumbler lock will be located in the interior of the casing 1. This tumbler lock may be mounted by boring a hole in the door 2 and the inner end thereof made to project into the casing 1, or may terminate flush with the surface of the door to which the casing 1 is fastened. The casing of this look encircles a barrel which is usually held in rigid relation with the said cylinder by means of tumblers which must be moved to proper position by means of a key indicated by the numeral 14 before the barrel can be turned in the cylinder of the tumbler lock 13. To the inner end of this barrel is secured an extension 15 which be polygonal in crosssection and pass into a correspondingly sha ed bore of a rotatabl mounted bushin P Y n or element 16 carried by this extension in the casing 1. On the inside of the bushing is an arm 17 and the retainer 9 may have a recess 18, through which the ends of the arm 17 may pass. When the retainer 9 engages the recess 11, the retainer can be made to release the bolt 3 upon the insertion of the key 14% into the tumbler lock 13 and the turning of the key to revolve the extension 15 and the element 16; whereupon the arm 17 will force the retainer 9 to withdraw the end thereof from the recess 11. Then, the bolt 3 can be moved back into the casing lrby rotation of the knob 8. Hence anyone on the outside of the inclosure can open the look if he has a key to fit the tumbler lock 13.

From the inside of the inclosure the bolt 3 can be withdrawn without a key by the rotation: of the knob 8 at the opposite end of the shaft 7. A head 19 on the outside of the casing 1, is secured to the retainer 9 by a shank which passes through an opening in the casing; therefore when the bolt is shot to full projecting distance and the end of the retainer 9 is forced into the recess 11, one on the inside of the inclosure need only pull on-the head 19 to disengage the bolt, then rotate the knob 8 on the inside of the inclosure to move the bolt back.

The belt is also provided in one side with another recess 20 in advance of the recess 11 and the top of the casing carries on the outside of the same a resilient strip 21 hearing a head 22 with a projection 23. In line with this projection the top of the casing 1 has an opening 2 1 and when the projection 23 is in line with the opening 24: the spring 21 tends to force the projection 23 through this opening into contact with the bolt 3. Tf, therefore, the bolt be moved into the casing to bring the recess 20 and the aperture 24 into registry, the projection 23 will pass through the opening 2 1 into this recess and restrict the morementof the bolt to a distance equal to the width of this recess 20. Under such circumstances the bolt cannot move to its full projecting distance and the terminal portion thereof which will stick out of the casing 1 into the opening 1 will be beveled from the edge of the door toward the top of the easing 1. This beveled face, when the door is shut. will be engaged by the striker plate on the frame of the door-and cause the bolt to be pushed back into the casing until the door is shut. Then, as the bolt comes into alinement with the aperture through the striker plate it shoots out of the casing as far as the projection will allow and passes into the aperture of the striker plate to hold the door closed until the bolt is again moved back. A spring 25 on the inside of the casing engages the inner end of the bolt when the projection 23 has entered the recess 20 and tends to move the bolt outward. The beveled end of the bolt is indicated by the numeral 26. The strip 21 may be. of any resilient metal or other substance and it will be fixed to the top of the casing by a rivet whichv will enable it to'be swung about on its riveted end as a pivot. Therefore when the bolt is allowed to project to its full distance as indicated in Fig. 1, the head 22 is pulled to make the proj ection 23 clear the recess 20 and the opening 24; and the arm 21 is then swung to carry the projection 23 out of line with the opening 24. Then there will be nothing to engage the recess 20 and the bolt can move out as far as required.

The operation and utility of the invention will now be clear. When a person on the inside of the inclosure wishes to lock the door 2 so that no one can open it from the outside of the inclosure, except with the properkey, he first makes sure that the projection does not extend through the opening 7 24, then he opens the door and goes out, pushing the bolt 3 back far enough to enable the beveled end 26 to engage the striker plate on the frame so that the bolt will snap through the striker plate when the door is completely shut. From the outside of the inclosure then, he turns the knob 8 to move the bolt 3 out of the casing 1 far enough to bring the recess 11 to the end of the retainer 9. 'The'retainer then enters this recess and secures the bolt. Then no one from the outside can open the door 2, except by inserting the key 14 and turning the knob 8. On the other hand the door can be opened from the interior of the inclosure Without a key simply by pulling down upon the head 19 and turning the inside knob 8; Whenever one wishes to adjust the locking device so that the door can be opened from either the inside or the outside of the inclosure without a key, he manipulates the head 22 to make the projection 23 engage the recess 20. Then the lock cannot move far enough to enable the retaining element to take effect.

The recess 11 is made deeper than the recess 20 so that the end of the retainer cannot enter the recess 20. Guide members 27 may be secured to the door and the inner face of the top of the casing 1 for the bolt 3 and this bolt may be provided with teeth not only on the top but on the bottom also, and the recesses 11 and 20 on one face may be duplicated on the opposite face, so that the bolt can be used on a door which opens in a different direction simply by turning the bolt on its longitudinal aXis through onehalf of a circle, particularly when we wish to mount the looks upon doors that do not all open in the same direction.

The casing 1 may be provided with a plate to close the bottom as well as the top. Of course when the projection 23 is not in the opening 24, the projection simply rests on the outside of the casing beside this opening.

In Figs. 4, 5 and 6 we illustrate a lock which is similar to the lock described above; with the exception of certain minor alterations. Instead of having the teeth 5, as already set forth, we make a deep recess 28 in the rear end of the bolt and put the.

teeth 5 in the upper and lower part of this recess thus locating the teeth in the top and bottom of the bolt as before; but the pinion 6 turns in the recess 28 and enables the bolt to be moved to project at one end through the casing through the opening 4 and to be withdrawn into the casing; By this device we canuse a smaller casing because the shaft the retainer to engage the bolt. Instead of the recess for the retainer being on the in side of the bolt we make a recess which is indicated at 11 in Figs. 4: and 5 in the bot-' tom of the bolt, duplicating this recess in the top the same as the teeth 5.

We also dispense with the recess 20 in the bolt, the strip 21, the head 22 and the open ing 24 and instead of these parts we employ a stop 29 on the top of the bolt to cooperate with the spring 30 secured inside'of the casing 1. The stop 29 may be simply a screw plug and the bolt may have an opening in the bottom" to enable the position of thisv plug to be changed when the bolt isto be used upon a door opening in a different direction. Normally this spring 80 acts as a part to' engage the stop 29 and arrest the bolt before it has moved to project far enough through the opening 4'to enablethe retainer 9 to enter the recess 11. Therefore, when one goes out and shuts the door after him, he must turn the pinion 6 to force the bolt to project far enough through the opening 4 to make the stop 29 push against the springBO until the bolt has carried the recess 11 into alinement with the end of, the retainer. Then the retainer engages the bolt and the door can not be opened from without except by the use of a key to turn the tongue 15 and push down the retainer9. When the retainer is thus pushed down the spring .30 acts to push the bolt back far enough tomove the recess 11 out of line with the retainer and then by turning the outside knob 8 the pinion 6 can be made to withdraw the bolt entirely and allow the door to be opened. Of course this retainer can be disengaged from the inside of the room by pulling down on the'head 19. V

To enable the lock to be used so that the bolt 3 can be withdrawn from without the inclosure by one having no key, the bolt 3 is simply pushed back until only the beveled portion26 projects from the casing 2, then the door can be snapped shut and opened from without, simply by turning the knob 8 and pinion 6; the spring30 then acting as a 1. The combination of bolt, a retainer to engage the bolt when projected toi'ull operative position, a keybperated element to disengage the retainer from the belt, a member independent of the retainer to project or Withdraw the bolt when disengaged from the retainer, and a part to limit the projection of the bolt to prevent the retainer from engaging same, rendering the retainer inefi ective and perniittii'ig the Withdrawal of the bolt by said member, said part being operable to release the bolt to permit it, Whenever desired, to move into position to been gaged by said retainer.

The combinationol' a bolt, teeth carried thereby, a retainer to engage the bolt When projected to full operative position, a keyoperated element to disengage the retainer from the bolt, a pinion to be then actuated to Withdraw the bolt, and a part to limit the projection of the bolt to prevent the retainer from engaging same, rendering the retainer ineffective and permitting the Withdrawal of the bolt by said member, said part being operable to release the bolt to permit it, Whenever desired, to move into position to be engaged by said retainer.

3. The combination of a belt, a retainer to engage the bolt when projected to full operative position, a. key-operated element to disengage the retainer from the belt, a member independent of the retainer-to be actoated to project or Withdraw the bolt, a f xed spring, and a stop on the bolt to be engaged by the spring to limit the pro ection of the bolt short or thepoint at which the'retainer en 'a 'es the bolt IBDClQ-YHI the retainer ill- U Q b effective and permitting the bolt to be wlthdrai'vn by said member, the spring being capable of: distension at will to allow the bolt to move into position for the retainer to engage it.
