r rock 7 Edwin v. Statia, sr., Detroit, Mich. Application November 7, 1955, Serial No. 545,201 2 4 Claims, c1. 70-276 This invention relates to dispensers and, in particuadapted to unlock the still further modified magnetic equipped with a lock 26. The money container 20 also lar, to money dispensers for paying delivering tradesmen.

One object of this invention is to provide a money dispenser for paying delivering tradesmen, suchas' milkmen, bakers, newspaperboys, postmen and the like, wherein the dispenser is provided with amagnetically-actuated lock which is unlocked with a magnetic key.

Another object is to provide a money dispenser of the foregoing character wherein magnetic keys of different configurations are provided in order to prevent'unlo'cking, the dispenser with the key of an unauthorized person.

Another object is to provide a money dispenser of the foregoing character wherein the magnetic lock is incapable of being unlocked by an ordinary magnet, but can only be unlocked by a magnetickey .with a speciallyshaped recess inthe end thereof.

Another object is tov provide a money dispenser having an indicating .device: thereon which is selectively movable into positions which indicate the particular tradesman whom it is desired to pay. .g

Other objects and advantages of the invention will hecome apparent during the course of the following description of the accompanying drawings, wherein:

Figure 10 is a cross-section similar to Figures 4 and 7, through a magnetic lock unlocked with a further modified key;

Figures 11 and 12 are respectivelyan end elevation 10, through a magnetic lock unlocked with a still fur-- ther modified key; and

Figures 14 and 15 are respectively an end elevation and a side elevation partly in section of a magnetic key has a lower portion 28 carrying a tradesmen-indicating device, generally designated 30. The bracket 24 is drilled as at 32 to receive fasteners by which it is secured to a suitable upright, such as the side of a house, and is secured by fasteners 34 to the upper portion 22 The latter is cup-shaped and preferably provided with a slot 36 through which money can be inserted in the container 20.

The upper end of the lower portion 28 is provided with an external surface 38 of reduced diameter which telescopes with the inner surface 39 of the upper portion 22 (Figure l) and which is provided with circumferentially-spaced lock bolt keeper holes 40, the upper edges 'of which coincide with a half-V-shaped bolt-locating outer part of theflock 26 and having a bore 46 therein 7 in which a lock bolt 48 of magnetic material is reciprocably mounted. The lock bolt 48 at its inner or forward end'Stl is configured to extend into the keeper hole 40 in locking engagement with one edge thereof, whereas the outer or rearward end of the bolt 48 is provided with a recess 52 in which is mounted a stop pin or stem 54 of non-magnetic material, such as synthetic plastic, brass or the like, with its outer end 56 preferably pointed and adapted to pass loosely through a hole 58 in the rear wall 60 of the housing 44. The bolt housing 44 is preferably upwardly inclined relatively to the side wall 42 of the upper portion 22 of the container 20.

cooperatively usable with the lock 26 is a magnetic aluminum-nickel-cobalt type and having in one ,end

thereof a' recess 64 of cross-section similar to that of the stem 54 and of a depth sufficient toreceive the projecting portion of the stem 54 when the bolt 48 is retracted'by the magnetic key 62. In order to prevent rotation of the bolt 48 within the housing 44, it is preferable to make both of them of non-circular outline, as shown in Figure 4.

The side wall 66 of the lower portion 2 8 of the money container 20 is drilled as at 68 to receive a pin 70 having heads '72 and 74 at its rearward and forward ends respectively, one of the heads 74 being conveniently formed by upsetting the end of the pin'either by itself or with the intermediate use of a washer (not shown). Rotatably mounted on the pin 70 for independent swinging relatively thereto are the inner ends of several indicator figurines 76, 78 and 8%! respectively, with friction Washers 82 and 84 between them. In order to indicate the kindfof tradesman, the figurine 76 representing the a baker is provided with the representation of a loaf of bread 7'7; the figurine 78 representing the milkman is pro vided with the representation of a milk bottle 79; and the figurine 8lltrepresenting a newsboy is provided with the representation of a newspaper 81. A compression coil spring 86 urges all of these figurines and washers into frictional engagement with one another. The reara ward end of the spring 86 engages an abutment disc or washer 88 which in turn engages the side wall 66 of the lower portion 28.

Figures 7, 10 and 13 show modified locks, the bolts ,48 of which are similar to the bolt 48 of Figures 1 and 4, but the non-magnetic stems 54a, 54b and 540 respectively are of different cross-sectional shapes adapted to enter the correspondingly-shaped recesses 64a, 6417 or 640 of the magnetic keys, generally designated 62a, 62b and 62c respectively.

In the operation of the invention, let it be assumed that each of the tradesmen to whom money is to be paid has a magnetic key 62 with a recess 64 therein of cross-section corresponding to the cross-section of the non-magnetic stem 54, and that the householder desires to pay the baker, for instance, for bread to be delivered. Accordingly, the householder moves the figurine 76 indicating the baker, into the uppermost position and inserts the money through the slot 36 or, alternatively, places it directly in the lower portion 26 of the container 20 before pushing it into the upper portion 22 thereof and locking it by means of the bolt 48. When the user pushes the telescoping portion 38 into the upper portion 22, the upper edge of the portion 38 engages the inclined end 50 of the bolt 48 and pushes it aside in the upwardly-inclined bore 46 against the opposing force of gravity thereon, the bolt end 50 dropping through the keeper hole 40 under the influence of the force of gravity when the hole 40 arrives opposite the bolt end 50. When the tradesman arives, for example, the baker, he sees that the vertical position of the figurine 76 indicates that money is in the container 20 of the dispenser 18 for him. Accordingly, he takes his magnetic key 62 from his pocket and applies the end containing the recess 64 to the end 60 of the bolt housing 44, with the recess 64 aligned with the hole 58 therein. The magnetic force of the magnet 62 magnetically attracts the bolt 48 and moves it upward within the housing 44, retracting the bolt end 50 from the keeper hole 40, so that the tradesmen can pull downward upon the lower portion 28 of the container 20 and i remove it from the upper portion 22, the recess 64 in the magnetic key 62 having received the rearwardlymoving stem 54. After removing the money from the lower portion 28 of the container 20, he replaces the lower half 28 within the upper half 22, whereupon the bolt 48 slides down the inclined bore 46 under the influence of gravity so that its inner or forward end reengages the edge of the keeper hole 40 and again locks the upper and lower portions 22 and 28 together.

In order to provide security and selectivity, the manufacturer of the dispenser 18 provides stems 54a, 54b and 540 of different cross-sections and with them magnetic keys 62a, 62b or 62c with recesses 64a, 64b and 640 of cross-section corresponding to the stem 54a, 545 or 540 respectively. The operation in each case is the same as that described above.

What I claim is:

1. In combination, an outer tubular member, an inner tubular member separably and telescopingly engageable with said outer tubular member, a lock bolt housing connected to said outer tubular member and having a guide bore therethrough, said inner tubular member having a lock keeper aperture aligned with said guide bore, a lock bolt of magnetically-attracted material reciprocably mounted in said guide bore for motion into and out of locking engagement with said keeper aperture in response to reciprocation of said lock bolt, said lock bolt having thereon a stop member of non-magnetic material projecting outwardly therefrom beyond said guide bore in the outwardly-reciprocated position of said lock bolt, and a magnetic key having a recess therein configured to receive said stop member in said outwardly-reciprocated position of said lock bolt.

2. The combination set forth in claim 1, wherein said stop member has a shape of predetermined cross-section and wherein said recess has a shape of corresponding predetermined cross-section telescopingly engageable therewith.
