10 Claims.
This invention relates to locks and refers particularly to cylinder locks of the type wherein the locking bolt is given a rotary motion.
In locks of this type, the locking bolt generally has a ninety degree travel between locked and unlocked positions, and as cylinder locks are now generally so constructed that the key can be inserted and withdrawn only when the cylinder is in one position of rotation, some form of lost motion connection must be provided between the cylinder and the bolt if it is desired,
to permit the key to be withdrawn and inserted in both the locked and unlocked positions.
While previous constructions did provide this lost motion connection between the cylinder and the locking bolt, they entailed the use of many parts which were difficult to assemble, and in general proved unsatisfactory.
It is therefore an object of this invention to improve the construction of locks of this character especially with respect to the manner in which the lost motion connection is established between the lock cylinder and the locking bolt. Another object of this invention is to provide 5 an improved construction'for the purpose described which reduces the number of parts re-- quired, and thus, effects a simpler and cheaper design.
With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as some within the scope of the claims. The accompanying drawing illustrates one complete example of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application of the principles thereof, and in which: Figure 1 is a side view of a lock constructed in accordance with this invention, having parts thereof broken away and in section;
Figure 2 is a cross sectional View through Figure 1 on the plane of the line 22;
Figure 3 is across sectional view taken on the same plane as Figure 2, but showing the locking bolt in its opposite position; and
Figure 4 is a perspective view of the inner end portion of the lock'casing.
Referring now particularly to the accompanying drawing in which like numerals indicate like parts, the numeral 5 designates the casing of the lock which is mounted in a support 6 and is bored as at l to rotatably receive a lock cylinder 8. The lock cylinder 8 is provided with the customary tumblers (not shown) to efiect a locking interengagement between the cylinder 5 and casing to secure the cylinder against rotation. Insertion of a proper key 9 into the keyway of the cylinder, the front end of which is exposed at the front of the support 6, retracts the tumblers and frees the cylinder for rota- 10 tion. The construction of these locking parts is such that the key can be inserted and withdrawn only when the cylinder is in one position of rotation.
The inner end of the casing has a counter- 15 bore ID to receive an enlarged inner end portion I! of the lock cylinder. The cylinder is inserted into the casing from itsinner end and is secured against longitudinal motion by an insert 12 driven into a transverse slot I3 in the 20 top of the casing at a short distance rearwardly of the bottom of the counterbore so that the insert I2 projects into an annular groove l4 encircling the enlarged inner end portion I I of the cylinder at this point. 25
At its extreme inner end, the cylinder has an enlarged head l5 and immediately forward of this head is an annular groove l6 interrupted at one point by a radial outwardly projecting lug IT. The groove I6 of the cylinder is in trans- 30 verse alignment with a round pilot bearing l8 concentric to the counterbore I0 and extending through slightly more than one hundred and eighty degrees of its circumference, the ends [9 and 20 of this round pilot bearing l8 providing 35 stops for a purpose to be hereinafter described.
Rotatably mounted on the bearing I8 is a locking bolt 2|. The bolt 2| is stamped from stiff sheet metal and has a round hole 22 centrally located with a lug 23 projecting radially in from 40' the periphery of the hole 22. The opposite ends of the bolt form locking ears and preferably have two diagonal corners 24 bent rearwardly to provide cam surfaces for engagement with keeper parts (not shown). 45
With the bolt properly positioned on the bearing I8, the lug 23 projects into the annular groove 16 in the cylinder to be engageable by the lug I! as the cylinder is turned, and inasmuch as the lug 23 enters the counterbore of 50 the casing through the cut-away portion of the bearing l8, it is also engageable with the stops formed by the ends l9 and 20 of the hearing.
The circumferential length of the lugs l1 and 23 and the distance between the stops I9 and 20 56 is such that when the cylinder makes one coming the counterbore between the edges of the pilot plete turn of three hundred and sixty degrees, the bolt is carried through ninety degrees of rotation, both limits of movement being accurately defined by the engagement of the lug 23 with either the stop l9 or 20, as clearly shown in Figures 2 and 3.
To hold the parts against rattling, a spring washer 25 provided with undulations circumferentially spaced is confined between the bolt and the enlarged head I5 of the cylinder.
In assembling the structure, the spring washer is first slipped over the front end of the cylinder and brought up against the head I5 on its inner end. Next, the locking bolt is eccentrically positioned over the front end of the cylinder and moved back into engagement with the spring washer, at which time its radial lug 23 is in line with the annular groove 16. With the bolt on the cylinder, the cylinder is then inserted into the bore of the casing, the pilot bearing I8 entering the round hole of the bolt. The parts are then secured against disassembly by driving the insert into the slot l3.
From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art, that this invention improves the construction 01 locks of this character, and that it particularly reduces the number of parts required to provide the desired lost motion connection between the cylinder and the rotating bolt.
