LOCK
Filed June 12, 1940 5%wnegas Patented Dec. 24, 1940 LOCK 4 George Hofmann, Boston, Mass, assignor to American Locker Company, Inc., Boston, Mass., a corporation of Delaware I I Application June 12, 1940, Serial No. 340,082
5 Claims.
This invention relates to locks and more particularly to a lock especially adapted for use in connection with coin controlled locking mechanism as disclosed in my Patent No. 1,933,263. As illustrated therein, a coin controlled locking mechanism is carried by a plate adapted to be mounted on and cover an opening in a vending cabinet, a lock l6 also carried by the plate being adapted to secure the plate to the cabinet. One object of the invention is to produce an improved lock of the nature of this look l6.
My improved lock employs a locking bolt of the swinging type and this bolt is located adjacent to the front end of the lock where it can swing into locking engagement with the rear face of the front wall of the cabinet on which the lock supporting plate is mounted. A further ob ject of the invention resides in the production of a relatively simple and novel assembly comprisn a centrally disposed post extending through the lock and supportingthe locking bolt and other parts thereon in very compact relation, the post and other parts being anchored against rotation and the locking bolt being rotatable thereon and adapted to be held in locked position by plungers housed within the assembly.
These and other features of the invention will be best understood and appreciated from the following description of a. preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawing in which,
Fig. 1 is a fragmentary front elevation of a vending or checking cabinet employing my lock,
Fig; 2 is a plan sectional view taken on the line 2--2 of Fig. 1,
Fig. 3 is an elevational sectional view taken on line 33 of Fig. 2,
Fig. 4 is a vertical sectional view taken on line 44 of Fig. 2 and showing the lock in locked position,
Fig. 5 is a front elevation of the lock,
Fig. 6 is a sectional view taken on line 66 of Fi 4,
Fig. '7 is a sectional plan view through the lock in unlocked position, together with the key,
Figs. 8 and 9 are perspective views of the two parts from which the key is assembled,
Fig. 10 is a perspective view of a sleeve,
Fig. 11 is a sectional view taken on line I l| l of Fig. 4 and showing the lock in rear elevation.
In the drawing I have illustrated my improved lock as used to secure coin controlled locking mechanism on a checking or vending cabinet. The coin controlled locking mechanism is carried on a plate I!) adapted to be received within an opening in a cabinet I2 having a door l3. The plate carries a lip M on its bottom end engaging the inner face of the cabinet and the lock I5 mounted on the top end of the plate has a looking bolt I 6 which can be swung upwardly into engagement with the inner face of the cabinet front wall, the bolt cooperating with the top end ll of the plate to grip the cabinet therebetween. The coin controlled unit, all parts of which are carried by the plate, can be removed merely by unlocking the lock l5. My improved lock is disposed on and about a centrally located post l8 having a flange 20 on and extending laterally outward of its front end. A sleeve 22 mounted for rotation on the 15 post abuts against the flange and has an enlarged boss 24 intermediate its ends. Fitted to the boss and extending over the front end of the sleeve is a cap-like member 26 carrying the locking bolt 16 rotatable therewith and projecting laterally outward therefrom. The member is secured to the sleeve by a pin 30 extending through the bolt and into the boss.
Mounted on the sleeve 22 rearwardly'of and in end engagement with the boss is a housing or second sleeve 32. A plate 34 non-rotatably engages a stud 35 on the rear end of the post and has end portions engaging within notches 36 in the sleeve 32. The outer end of the stud is riveted over to hold the plate thereon, and the plate holds the parts assembled on the post and prevents rotation of the sleeve 32 relative to the post. An arm 38 extending outwardly from the plate is adapted to be engaged with supporting abutments to hold the post against rotation.
The sleeve 32 is bored to receive a plurality of locking plungers 40 normally forced forwardly by springs 42, and a plurality of corresponding bores having pins 44 therein are provided in the boss 24, the two sets of bores being respectively in alignment when the lock is in the locked and key-inserting position. The springs normally force the plungers 40 to the locking position shown in Fig. 4 wherein the pins abut against a flange 46 on the member 26.
The key for the lock comprises two pieces 48 and 50 in the assembled relation shown in Fig. 7. The stem 48 has recesses 52 of different depths on its front end for receiving the pins 44 and the piece 50 has a bit 54 extending inwardly of the stem. The flange 20 and sleeve 22 are notched at 56 and 58 to receive the bit 54. Pressure of the key against the pins 44 forces the pins rearwardly and the plungers 40 to the flush position shown in Fig. '7, whereupon the key can rotate the sleeve 22 and the locking bolt to an adjacent locking or unlocking position. The notch 58 is arranged to be in alignment with the notch 56 when the bolt '28 is in the locking position of Fig. 1 at which position the key can be removed. Engagement of the bit with the flange prevents removal of the key from any other position.
The cylindrical portion 32 of the lock is adapted to rest in the lower half 60 of a cradle formed on the top end of a frame 62 carried on the rear face of the plate it. The upper half 64 of the cradle is an independent piece and has a sliding dovetailed fit into the member 6!] at 65. The piece 6 1 is recessed to receive at -88 the arm 38 of the lock whereby to hold the post I8 and thecylinder 32 from rotation. The piece 64 is held in forward position by bolts Hi and a spring 72 keeps I the lock pressed forwardly with its locking bolt 23 in contact with the rear face of the cabinet front wall. Pressure of the key in the lock first compresses the spring 12 whereby forcing the lock rearwardly and continued pressure forces the plungers d0 rearwardly to the flush position of Fig. '7 whereby permitting the locking bolt to be rotated on the post.
Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is,
1. A look comprising an inner centrally disposed post, a member mounted for rotation on the post and carrying a locking bolt rotatable therewith and projecting laterally outward therefrom, a housing concentric with the post rearwardly of and in end to end relation with the member, means supporting the housing against rotation about the longitudinal axis of the post, the housing and member having a pluraility of pairs of longitudinal bores therein respectively arranged to be in alignment when the member is in one rotary position relative to the housing, a plurality of plungers respectively in the bores in the housing, springs for forcing the plungers longitudinally into the corresponding bores in the member, and cooperating key-receiving pins in the bores in the member.
2. The lock defined in claim 1 plus a sleeve mounted for rotation on the post, said member being fixed to the sleeve and the housing being a second sleeve mounted on the first-named sleeve.
3. A lock comprising an inner centrally disposed post, a sleeve mounted for rotation on the post and carrying a member having a locking bolt projecting laterally outward therefrom, a second sleeve on the first sleeve rearwardly of and in end to end relation with a portion of the first sleeve, a plate carried nonrctatably on the inner end of the post and engaging the second sleeve to prevent rotation and rearward movement thereof relative to the post, an arm extending outwardly of the plate laterally beyond the second sleeve for engagement with an abutment to anchor the plate and post against rotation, and a plurality of locking plungers carried by the second sleeve for cooperating with bores in the first sleeve.
4. A look comprising an inner centrally disposed post having a flange integral therewith at its front end and extending laterally outward therefrom, a sleeve rotatably mounted on the post adjacent to the flange, a cap-like member mounted on and over the front end portion of the sleeve and having a locking bolt rotatable therewith and projecting laterally outward therefrom, the flange and adjacent portion of the sleeve being notched to permit passage of a key bit, the key being held from withdrawal when rotated to a position locating the bit behind the flange, a housing rearwardly of and in end to end engagement with a portion of the sleeve, means supporting the housing against rotation about the longitudinal axis of the post, and a plurality of locking plungers carried by the housing for cooperating with bores in said portion of the sleeve.
5. A lock-comprising a post, a member mounted for rotation on the post and carrying a locking bolt rotatable therewith and projecting outward therefrom, a housing on the post adjacent to the member, means on the ends of the post for holding the member and housing assembled thereon and including means preventing relative rotation of the post and housing, locking plungers carried bythe housing for cooperating with bores in the member, and cooperating key-receiving pins in the bores in the member.
