Description

Patented Aug. 3, 1925.
UNITE@ STATES LOUIS J'. HUGUES, OF ToPEKA, KANSAS.
- DOORLOCK.
Application filed September 25, 1925. Serial No. 58,628.
This invention relates to a combination lock for doors and the like, the general object ot the invention being to provide a lock bolt in the knob of the lock` for holding the latch bolt in locking position, with com bination means in the knob tor controlling the lock bolt.
Another object of the invention is to provide means actuated by the turning ot the knob for moving the lock bolt into operative and inoperative position.
A further object of the invention is to provide improved means tor moving the latch bolt by a turning movement of the knob. Y
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specii'ically pointed out in the appended claims.
In describing my invention in detail, rer"- erenc-e will be had to the accompanying f drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Y Figure 1 is a sectional View through the improved lock and the barrier on which it is used.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a vertical sectional view through Figure 1, showing the sliding members in elevation.
Figure i `is a view of the latch bolt.
Figure 5 is a view of the small sliding member.
Figure 6 is a view ot the large sliding member.
In these views, A indicates a door or other barrier and B the frame thereof which carries the keeper C Jfor the latch bolt 1 which is slidably mounted in the lock casing 2 which is secured to the barrier. This latch bolt is provided with a recess 3 and a spring 4 tends to hold the bolt in locking position. A cam 5 on the stem 6 of a knob 7 operates in the recess and acts to retract the bolt from the inside ot the building when the knob is turned. The boltis provided with a groove 8 tor receiving a part ot a sliding block 9 which is provided with a projection 10 and a second sliding block 11 is arranged between the bolt and a part of the casing and has a cut-away portion for receiving a portion ot the block 9.. This block 11 is also provided with a projection 12 which abuts the projection 10 and the bolt is provided with a lateral projection 13 which is engaged by an end portion ot the block 9. The bolt land the blocks 9 and 11 are guided in their sliding movement by the parts 14e and 15 ot the casing, which are held to the casingby the screws 16. It will be seen that the spring 4t will tend to hold ,the bolt in projected position and that when the bolt is moved to projected position, its projection 13,v striking the rear vof the block 9, will carry said block with the bolt, though the bolt can be retracted by the knob 7 and its cam 5 without movement of the blocks 9 f,
and 11. I
The combination part of the lock is similar to the combination lock forming the subject matter ot an application filed by me on September 25, 1925, Serial No. 58,630, though the `barrel of the lock is made in the 'form ot a knob in this case.
This barrel is shown at 17 and lis rotatably mounted on the extension 18 ot the lock casing in which the bolt 19 isslidably arranged, the bolt being adapted to engage a recess 2O in the block 11 Jiorholding said block in projected position. rThe knob or barrel 17 is provided witha cam recess 21 into which the projections 10 and 12 extend. When the knob is turned to the right, one end of the recess will strike the projection 12 and project the blocks 9 and 11 to the right. When the knob is turned to the left, the other end of the recess will strike the projection 1() and move the blocks to the lett, and in this movement the block 9 engaging the projection 13 will also retract the latch bolt 1. Thus the knob is used for retracting the bolt 1, but when the bolt 19 occupies the recess 20, the block 11 cannot be moved by the knob, so that the bolt 1 cannot be retracted from the exterior of the door though it can still be retracted by the knob 7 on the interior of the door. By omitting this knob 7 and its associated parts, the bolt can be used as a dead bolt. The end of the knob occupies a recess 22 in the casing and the screws 23 which hold the casing on the door are covered by the knob.
The bolt 19 has the block 24 sliding thereon and is held against the head 25 or" of the recess 28 in the block. A lighter spring 29 acts to project the bolt when the spring 26 is contracted. The combination rings are shown at 30 With their screws 31 engaging the annular grooves 32 and the longitudinal groove 83 in the bolt 19, the char acters on the rings being seen through the Windows 84 formed in the knob and the extension. The bolt 19 is held against turning movement by the screw 85 and a spring plunger 36 holds the knob on the extension, While the parts are in locked position.
In order to permit the rings to be changed so `as to change the combination, a depression 37 having a curved bottom is formed in the block 11 for receiving the end of the bolt 19, this construction preventing an unauthorized person from reading the right combination of the lock.
From the foregoing, it Will be seen that I have provided a knob for retracting the latch bolt with means in the knob, operated by combination rings, for preventing the knob from retracting the latch bolt, with means on the interior part of the door for retracting the bolt with the knob in either its locked or unlocked position.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
l desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall WithinV the scope of the appended claims.
fha-t I claim is 1. A lock of the class described, comprising a casing, a spring pressed latch bolt therein, an inside knob, means associated therewith for retracting the bolt, an outside knob, means for retraeting the bolt by the rotary movement of the outside knob, a bolt carried by the outside knob for locking the latch bolt in locking position, means for actuating the bolt in the knob by the turning movement of the knob and combination means for controlling` the movement of the bolt in the knob.
2. A lock of the class described, comprising a casing, a spring pressed latch bolt'therein, a pair of sliding blocks, abutting projections on the blocks, a projection on the bolt rotatably connected with the casing and havf ing portions engaging the projections for moving the blocks, a bolt in the knob and actuated by the turning movement of the saine for locking thev blocksagainst movement by the knob and combination means tor controlling the movement of' the bolt in the knob.
3. A lock of the class described, compristherein, a pair of sliding blocks, abutting projections on the blocks, a projection on the bolt engaged by one Vof the blocks, a knob ro'- tatably connected with the casing and having portions engaging the projections for moving the blocks, a bolt in the knob and actuated by the turning movement of thev saine for locking the blocks against movement by the knob, combination means for controlling the movement of the Vbolt in the knob and means `for preventing' an unauthorized person from gaining the proper manipulation ot the parts. V
In testimony whereof I affix my signature.
