Application October 13, 1947, Serial No. 779,476
Claims.
My invention relates to a lock and key, more particularly to a combination lock and key therefor, and the objects of my invention are:
First, to provide a lock and key of this class which are very simple and easy to operate;
Second, to provide a lock and key of this class in which the lock thereof is very diflicult to pick;
Third, to provide a lock of this class which may be partially locked and readily opened by a pin or the like when it is desired to latch a door or truck lift in certain position temporarily;
Fourth, to provide lock of this class having a tumbler operated in combination with a pivoted latch whereby both said pivoted latch and said tumbler must be in certain position before the lock may be opened;
Fifth, to provide a lock of this class in which a pivoted latch may be readily operated in combination with a slide plate which prevents one end of said latch from becoming locked while the other end is being pivoted out of locked position, providing sufficient complexity of the lock in order to prevent unskilled persons from opening the same;
Sixth, to provide a lock of this class employing an intricate combination of locking operations which must be well known in order to open the lock;
Seventh, to provide a lock of this class which is very strong; and
Eighth, to provide a lock of this class which is very simple and economical of construction, efiicient in operation, and which will not-readily deteriorate or get out of order.
With these and other objects in View, as will appear hereinafter, my invention consists of certain novel features of construction. combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference be ing had to the accompanying drawing and to the characters of reference thereon forming a part of this application in which:
Figure 1 is a vertical sectional view of my lock; Fig. 2 is a rear elevational view thereof taken from the line ,22 of Fig. 1 showing portions broken away and in section; Fig. 3 is a front elevational view of my lock; Fig. 4 is a front elevational view of the dial thereof; Fig. 5 is a side elevational view of the key for my lock; Fig. 6 is a similar view taken 90 to that as shown in Fig. 5; and Fig. '7 is a longitudinal sectional view taken from the line T! of Fig. 6.
Similar characters of reference refer to similar parts and portions throughout the several views of the drawing.
The frame plate I, separable members 2 and 3, latch latch bar 5, tumbler 6, tumbler shaft I, face plates 8 and 9, spring Ill, slide plate I I, strap I2, dial I3, key frame I4, key plunger I5, and the back plate I6 constitute the principal parts and portions of my lock andkey.
The frame I is normally secured to the inner side of the separable member 2 which may be a door or a door frame, or the separable members 2 and 3 may be the body and lid of a trunk, or the like, as desired. The frame I is provided with a fulcrum la thereon projecting from the rear thereof over which the latch 4 is pivoted. This latch 4 is a resilient plate spring latch having latch pins 411 and 4b projecting through openings Ib and la in the frame plate I. Corresponding openings 2a and 2b in the separable member 2 are provided through which the latch pins 4a and 4b respectively are adapted to extend. The spring I0 surrounds the latch pin 4b and bears against the inner side of the frame plate I tending to hold the latch pin 4a in the position as shown in Fig. 1 of the drawing. On the upper end of the frame plate I is a projecting latch pin Id adapted to pass through the slot 6a in the drum shaped tumbler 6. This tumbler 6 is fixed on the shaft I which is journaled in the separable member 3 and back plate I6, as shown best in Fig. 1 of the drawing. The shaft 7 is provided with a bore la having internally opposed slotted portions Ib therein adapted to be engaged by projecting pins I l-a of the key plunger I5, as shown best in Figs. 5 and 7 of the drawing. On the other end of the shaft I is a dial I3 having numerical designations as shown best in Fig. 4, which may be viewed through the opening 9a in the face plate 9. This face plate 9 is provided with a central opening 9b therein, through which the key, as shown in Figs. 5, 6 and 7 may be inserted to extend. into the bore lb of the shaft 1. The latch bar 5 is provided with a hinge portion 5a intermediate its ends, and is secured to the face and back plates 9 and I6 respectively at its upper end, and this latch bar 5 is vertically movable out of the strap I2 when the lock is unlocked for separating the separable members 2 and 3. The strap I2 is provided with a central opening I20. therein for the insertion of a pin to depress the latch pin 4a and remove it from interfering relation with the opening 5b in the latch bar 5 through which it is adapted to extend. The latch bar 5 is provided with a similar opening 50 in alignment with the latch pin 412 over which the slide plate II may be slidably shifted by means of the button Ila projecting at the front of the face plate 8. This button Ila extends through an elongated slotted portion Ba, and a correspondingly elongated slotted opening Ed in the latch bar 5. At the inner side of the lock I have provided a cover I'I, not shown in Fig. 2 of the drawing which prevents the intricate mechanism of my lock from being tampered with, or damaged. It will be noted that this cover I! is separated at Ila on a common. line with the joinder of the separable members 2 and 3.
The operation of my lock and key is substan# tially as follows: I
In order to open the look, as shown in Fig. 1 of the drawing, the slide plate II is first forced upwardly into interfering relationship with the pin 41) on the latch 4 in order to prevent the same from passing into the opening 50 when the lower pin 4a is pushed backWa-rdly by means of a nail or other object inserted through the opening I2a of the strap I2. The small diameter of the opening IZa accommodates only a small member so that when the latch pin 4a is forced backwardly out of interference with the opening 51) of the latch bar 5, the latch bar 5 may be slid upwardly into interfering relationship with the end of the latch pin 4a, thus permitting the latch bar 5 to be readily slidably separated from the separable member 2. When a person not versed in the use of my lock attempts to insert a pin through the opening In and pivot the latch member 4, he neglects to shift the slide plate II and in such a condition the latch pin 42) projects through the opening 50 of the latch bar 5, preventing slidable removal of said latch bar 5 from the strap I2. It will be noted that the slotted portion 6a of the tumbler 6 must be in alignment with the pin Id on the frame I in order to separate the separable members 2 and 3. If the tumbler 6 is turned so that the slotted portion 6a is out of alignment with the pin Id, the lock cannot be opened. In order to completely lock my lock, the slide plate II must be shifted downwardly, as shown in Fig. l, permitting the spring ID to force the latch pin 4a through the openings 2a and 5b in the separable member 2 and latch plate 5 respectively. Then the tumbler 6 must be turned so that the slot 6a is past the pin Id providing double locking of the separable members 2 and 3 as desired. In order to turn the tumbler 5, the key as shown in Figs. 5 to '7, is forced into the bore Ia of the shaft I, then the plunger I5 is forced downwardly as indicated by solid lines in Fig. 5, extending the pins Ida of the key frame I4 which are then extended into the slotted portion 1b in the side wall of the shaft I. This places the pins I la in shear, permitting the operator to turn the handle portion Ib of the key frame I4 for rotating the tumbler 6 as desired. It will be noted that the dial I3 provides an indexing means visible through the window 912 of the front plate 9 for identifying the original location of the dial in order to precisely set the slotted portion 6a of the tumbler 6 adjacent the pin Id so that the tumbler, 6 may be removed over the pin Id when the latch bar 5 is released by the latch member 4. The hinge 5a of the latch bar 5 accommodates arcuate travel of one of the separable membersZ or 3 when they are forced apart.
Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope and arrangement substantially as set forth in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patcut is:
