CATCH LOOK.
APPLICATION FILED SEPT. a, 1911.
Patented 001;. 28, 1913.
OLAF J. SUNDGAABD, OF ST. PAUL, MINNESOTA.
CATCH-LOCK.
Specification of Letters Patent.
Application filed September 5, 1911. Serial No. 647,680.
To all whom it may concern:
Be it known that ll, OLAF J SUNDGAARD, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Catch-Locks, of which the following is a specification.
My invention relates to improvements in catch locks and its object is to provide a lock that may be operated as an ordinary catch or friction lock under spring pressure and may be readily adjusted to act as a positive lock or be disconnected entirely, and to provide for such a look, a spring tension that may be readily adjusted from the outside to make the latch of the lock as stifi as desirable. My device is also adapted to be applied as a lock in a number of different positions without materially changing the make up of the parts or their action.
In the drawing with which I have illustrated my invention and which forms part.
of'my specification, Figure 1 is an elevation showing my device arranged to act as a simple catch lock; Fig. 2 is a sectional plan of the lock on the line X--X, Fig. 1; Fig. 3 is an elevation partly in section, showing my device in locked position; Fig. 4 is another elevation of the lock in the position shown in Fig. 3, and partly in section to show the operation of the stop; Fig. 5 is an elevation of the lock showing the latch held inoperative; Fig. 6 is an elevation of an alternative form of the lock, and Fig. 7 is another elevation of the same form of device.
In the above drawing I have shown a look A having a casing 2 on which is mounted a latch 3 pivoted on a rivet 4-. The latch 3 has a catch part 5 formed with an engaging face 6 diagonal to the line of movement of the locking parts. The catch part 5 is shown extending outside the casing 2 but may be formed within the casing if desired. The opposite end of the latch is formed with a transverse lug 8 having an aperture to re ceive an adjusting screw 9 which carries a spring 10 operating the latch 3. The screw 9 has a screw head 11 on the outside of the casing 2 for adjustment and turns in a nut 12 which is of irregular shape and adapted to be held from turning by the sides of the casing during the turning of the screw 9. The spring 10 is a coiled compresslon spring lying about the screw 9 and confined between the nut 12 and the lug 8 through which the screw passes, hold the lug 8 elevated as far as possible thus depressing the catch part 5 of the latch.
A cooperating locking member B is provlded which may be attached in suitable manner to a door C as illustrated while the lock A is attached to the door casing D. Either of the locking parts may be attached to the movable part D and the parts C and D may represent the parts of a box, window or other similar structure. The locking member 13 is formed with a shoulder 13 which has beveled faces 14 adapted to impinge on the catch part 5 of the latch 3 and tends to operate it in opening and closing the door C.
On the outside of the casing 2 is pivoted a stop 15 having a thumb piece 16 by which it may be operated rotatively upon the outside of the casing, and a lug 17 extending inward through an aperture 18 in the wall of the casing. The stop 15 is so positioned on the casing with relation to the latch 3 that it may be moved into a position with the lug 17 above the lug 8 of the latch 3 in its open position or below the lug 8 in the closed position of the latch and in these positions as illustrated in Figs. 3 and 5 is adapted to prevent the movement of the latch from one position to the other. Thus the step may be above the lug 8 locking the latch open as illustrated in Fig. 3 or may be below the lug 8 locking the latch in closed position as illustrated in Fig. 5. Lugs 30 are shown at the sides of the casing by which the casing 2 is fastened to the door casing-D.
In Fig. 6 I have shown an alternative form of my device adapted to a different mounting of the lock. Lugs 20 are shown at one edge of the casing of the lock E by which it may be attached and the casing has closed sides 32 and an open side 33. A latch 21 is shown similar in action to the latch 3 but in a reversed position with the catch part 22 turned upward and the coiiperating locking member F formed with a down turned shoulder part 23 adapted to engage the catch part as previously described. A lug 35 is formed below the latch 21 in which the adjusting screw 9 operates with a spring 10 identical in form and action with those shown in Figs. 1 to 5.
A stop 24 is hown similar in form and action to the stop 15 but it is pivoted on one edge of the casing E and rotates laterand is adapted to Patented Oct. 28, 1913.
ally on the casing into and out of engagement with the faces 25 and 26 on the extremity of the latch 21.
A stop 27 is formed integral with thecasing of the lock E and lies in the path of the end of the latch within the casing to limit its motion in the locking direction. On the lock A a stop 28 is used having the form and action, identical with the stop 27 in connection with the latch 3.
In operating my device, the lock A or E is attached to either the fixed or movable part, C or D and the corresponding cooperating members B or F are fixed to the other part. If the lock is to be used as a latch only the stop 15 or 24 is rotated out of connection with the latch of the lock and the door may be opened and closed at pleasure, being held by the friction of the catch part of the latch when in closed position. This friction may be adjusted as described by means of the screw 9. When the door has been closed, it may be locked closed by rotating the stop into engagement with the latch of the lock, holding the latch in engagement with the cooperating member. By placing the stop in the position illustrated in Fig. 5, above the lug 8 of the latch 8, the latch may be held out of engagement with the cooperatin member and permit the free movement of the door.
In accordance with the patent statutes I have described the principles of operation of my invention together with the appa-' .ratus which I now consider to represent the .best embodiment thereof but I desire to have it understood that the construction hown is only illustrative and that the invention can be carried out by'other means and applied to uses other than those above set forth within the scope of the following claims.
, tachably Having described my invention, what I claim as new and desire to protect by Letters Patent is 1. In a lock for a door, a pair of locking members adapted to engage each other dcto lock said doc-r, one of said memfixed rigid and the other pivota screw passing bers being ally mounted in a casing, freely through said casing and the inner extremity of said pivoted member, a nut threaded on said screw, and a spring mounted on said screw and interposed between said nut and the inner extremity of said pivoted member; whereby when said screw is turned said spring is compressed or released to vary the tension on said pivoted member, substantially as described.
2. In a lock for a door, a casing, a pair of locking members one of said members being fixed rigid and the other being pivot-- ally mounted in said casing, a screw passing freely through said casing and the inner extremity of said pivoted member, a .nut threaded on said screw having a projection which is adapted to engage said casing to hold said nut, a spring mounted on said screw and interposed between said nut and the inner extremity of said pivoted member and a stop pivoted on the outside of said casing having a lug projectlng into a slot formed therein, said lug being adapted to engage the inner end of said pivoted member to lock the same in two positions substantially as described.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
OLAF J. SUNDGAARD.
