7 Claims.

My application is a division of my copending application Serial No. 585,152, filed March 2'7, 1945, now Patent 2,580,400, issued January 1, 1952, and entitled Parking Meter and Coin Slot Therefor, and the invention relates to parking meters, for use along streets, roadways and in conjunction with vehicle stalls and parking areas for example.

An object of my invention is the provision of a simple, practical and inexpensive parking meter of rugged construction having a cam feed means, forming an integral and essential part of the same, which is adapted for setting timing mecha-- nism of the apparatus to initiated position while feeding a coin.

Another object is to provide a device of the character indicated wherein driving energy for included set-initiated timing means is stored as an incident to the time-setting operation and in which energy imparted to coin feeding means of the meter is stored for driving the meter timing means.

Another object of my invention is the provision, in a device of the character indicated, of timing apparatus for selective setting to measure any one of several differing periods of time corresponding to different coin values payable to the meter.

A further object is to provide coin feed means in a parking meter, by which an inserted coin is automatically fed to effect the setting of associated timing mechanism only after external control over the feed means is relinquished; also the provision of a simple arrangement for encasing or housing the timing and coin feed mechanism; and coin receiver means for passing coins through the meter casing, which while either active or inactive, precludes tampering with the inner workings of the meter through the coin passage.

Another object of my invention is the provision in coin feed means of the character indicated of a coin receiver for passing genuine coins through the meter housing and for arresting spurious coins for return to the receiver outlet all while affording protection against external tampering.

A further object of the invention is to provide a device of the character indicated wherein the receipts that have accumulated incident to use are collected within the meter casing in a coin box characterized by certain advantageous features for emptying the same.

Other objects in part will be obvious and in part referred to hereinafter.

The invention accordingly consists in the combination of elements, features of construction and 2 arrangement of parts as described herein and particularly set forth in the claims at the end of this specification.

In the accompanying drawings, in which like reference characters denote like parts throughout the several views, there is illustrated a parking meter embodyin certain features of my invention.

Figure 1 is a front elevation view of a preferred form of my parking meter;

Figure 2 is a partial sectional view in elevation along the line 22 of the meter housing with the meter operating mechanism removed;

Figure 3 is a fragmentary sectional side elevation view of the meter coin deposit box along a line 33 of Figure 1, showing the coin box door closed;

Figure 4 is a view similar to Figure 3 showing the coin box door open;

Figure 5 is a schematic isometric exploded view of meter operating mechanism in which the interaction of certain movable parts are illustrated;

Figure 6 is a front elevation view of the meter mechanism;

Figure '7 is a plan view corresponding to Figure 6;

Figure 8 is an exploded isometric view of a pre ferred coin receiver and its mechanism.

Referring now, more particularly, to the practice of my invention, attention is directed to the drawings, notably Figures 1 and 2. The meter will be seen to comprise an external housing [0 (Fig. 1) into which is seated a housing door II. The door is held in place by a screw type lock [2 which engages with post l3 fixed into the housing as best illustrated in Figure 2. The upper part of the door is cut away to provide a glass window I4 for revealing a time indicator and signal plate which is to be discussed in detail later. A similar Window for revealing a like time indicator and signal plate is provided in the back of the housing. In the housing door I I there is a coin window H5 which displays, from inside, the last coin which has served to set the meter. A coin receiver 33 for manipulation in setting the meter extends through the right hand side of the housing (Fig. l). The lower portion of the housing comprises a coin deposit chamber is for receiving coins after display of the same at window [6. The housing is sturdily reinforced with reinforcing ribs l9 and on inside walls is shaped to conform with the curvular edges of face plates 20, 20a and. 20b (shown in Fig. 6) so that the meter mechanism is firmly held in place in the housing without necessity for bolting and yet is easily removed.

After the coins have enabled setting of the meter for a paid-for parking period, which operation will be discussed later, they are released into coin chamber 2I enclosed by coin retaining wall 22 and coin chamber door 23. Door 23 is firmly locked by key 24 and latch 25. Attached to door 23 are

lever arms

26 and 21 which restrict outward movement of the door within limits of rotation about

hinges

28 and 29. The lever arms 23 are held in position shown in Figure 3 by means of spring 29. When key 24 is turned in a clockwise direction, latch 25 is rotated clear of latchstop 33. Following this the operator can open the coin chamber door with one hand and with the other hand collect coins which are now free to slide (see Fig. 4) from coin retaining wall or bottom 22 and down between seating elements 3I located one on each side of the bottom of the door for the purpose of seating the door in position when closed and for supporting the door (when the door is in open position) on ledge 3Ia of the meter housing. In Wide open position, the door extends lever arms 2! and 28 on each side to their full run which prohibits complete removal of the door. By this hinged action, the door can be pulled free bodily with one hand without danger of dropping and when released slides back under action of spring 23 and guided by seating elements 3 I, to closed position. I

In Figure 5, substantially all frame work, face plates, housings, and the like, of the meter have been omitted tofacilitate a clearer understanding .of certain features of my invention. The mechanism illustrated is adapted for receiving a coin, for example a nickel or apenny, which is inserted in outside end of slot 32 of coin receiver 33;. The receiver then is pushed in (counterclockwise) for delivering and depositing the coin to a cooperating carrier or slide for a feeding the coin in a manner more particularly discussed hereinafter. This motion of the receiver istransmitted along shaft 34 to sector gear 35 which in turn causes gear 33 and pinion 31.130 rotate clockwise driving rack 33 to the right as indicated by arrow in Figure 5. The rack 38 is guided during movement by guide rod 39 whose position is fixed. y

The ,coin carrier or slide 43, composed of two parallel plates M connected by

lugs

42 and 43 moving in slot 44 (Fig. 6) provided in parallel faced fplates20a and 2% (Fig. is rigidly attached to rack 3'8 by connecting plate I25. The plates 20a and 2% form the walls of a compartment for the actuating coin as appears more fully hereinafter. A bottom plate 200 between the plates 20a and 23?) adjacent slot 44 (see Fig. 6) forms a floor or track for supportin the coin during the carrying action. As the rack is driven to the right, so is the slide such that when coin receiver 33 has moved down through the entire path of its arc, the coin slide has moved in synchronism toits extreme right hand position. At this point, the coin is discharged from the receiver (this will be described in detail later) and drops between platesZUa and 23b and onto bottom plate or track 230 to seat just in front of lugs 43. v r I The coin receiver 33 referred to hereinbefore, in a preferred form (as illustrated in exploded view in Fig. 8), is movable between fixed side housing members H3 and H4 and through fixed front housing member "5 which in the drawing have been exploded out for better revealing certain parts of the receiver. It will be understood that the housing -members just mentioned form a part of the meter housing III. The receiver proper includes a casing made of chambered portion 33a having an open side and easing plate 33b for covering the open side. The casing is mounted on connecting arms H6 and II! which are attached to shaft 34 for rocking motion with the shaft as an axis. By this arrangement, the receiver casing is free to reciprocate through the meter housing, that is, through front housing member H5.

Coin entrance slot I I3 and coin exit slot I I9 located in opposite faces of the coin receiver casing are obliquely situated With respect to each other, such as illustrated in Figure 8. A coin passage assembly I20 fits into interior chamber I2I of the receiver casing against coil spring I22. The coin passage assembly I20 consists of a front face plate I23, back face plate I24, two separated coin passage plates I25 one of which has a slotted opening I23, upper and lower follower posts I2I, a slot I28 in the front face plate and a slot I29 in the back face plate. Between the plates I25 and preferably in the same plane with the bottoms of slots I28 and I29, is a coin passage bottom enabl'ingfree feed of a coin in either direction through the passage assembly. Slots I28 and I29, although on the oblique with respect to each other, are positioned on the vertical to enable sequential alignment thereof with the space between the coin passage plates I25.

The casing plate 33bencloses the coin passage assembly in chamber I2I, and has upper and lower holes I3I therein in such position as to permit entry of the follower posts I21. The plate is shown cut away to reveal a permanent magnet I32 attached thereto on the inside face in such position that when the coin receiver is assembled the magnet protrudes through slotted opening I26; the plate being securely mounted, as by means of screws, to close off the open side of chambered portion 33a of the casing.

Considering now that these parts are assembled as explained above, the operation is as follows: When a coin (either a penny or 'a nickel) is inserted in com entrance slot II8 of coin receiver 33, it passes through slot I28 in the front face plate of coin passage assembly I20 and then into the slot between coin passage plates I25. These are maintained directly in line in the following manner: The follower posts I21 which are attached to the coin passage assembly I20 and protrude through holes I3I in casing plate 33b are riding against the inside wall of the housing member IM. This wall is machined to provide a cam surface I33 (the housing member is cut away in Fig. '8 to illustrate this). Whenthe coin is first inserted, the follower posts 121 are riding against an upper section of the cam surface I33 which projects inwards so that the coin passage assembly is forced well back into interior 'cham. ber I2I of coin receiver 33, in which position coin entrance slot I I8 and the slot between 'coin passage plates I25 are lined up (note however that at this point the coin exit slot H9 is not lined up with 'the "slot between the coin passage plates I25 so that the coin cannot pass out of the exit end of the coinreceiver 33). With the 'coin lodged in the slots between the coin passage plates I25, the person depositing the coin pushes receiver 33 forward rotating it about shaft 34. As it moves forward the follower posts I21 being guided down cam surface [33 begin to mo've outwards forced by spring I22 as the follower posts I2'I enter the bevelled portion of the 'cam surface 133a. when the follower posts have v .5 reached the end of the bevelled portion of the cam surface which occurs at least before com-- pletion of the in stroke of the receiver reciprocating movement, the coin passage assembly has shifted so that the slot I29 in the back face plate of the coin passage assembly is now lined up with the coin exit slot H9. The coin is now free to drop out of the coin receiver by gravity onto the coin slide 40. The movement of the coin passage assembly, therefore, is so designed that when the coin is first deposited it will not pass through the receiver and is held in the coin passage assembly until the coin receiver has been pushed all the way in. Once the receiver is pushed in no tampering can be brought to bear upon the coin for alignment no longer exists with the inlet opening.

In the event that a slug is deposited, the slug is rejected preferably in the following manner: As the slug enters the coin entrance slot and then into the slot between the coin passage plates I25 the permanent magnet I32 on the rear face of the coin receiver plate I36 is held away from the slug because the coin passage assembly I is held back away from it by follower posts I2! being depressed by cam surface I33. As the coin receiver 33 rotates forward, however, coin passage assembly I20 moves forward in chamber 33a so that now the slug is directly adjacent to magnet I32. Since slugs, as distinguished from genuine coins, are generally of a ferrous base alloy and are therefore magnetic, the magnet I 32 grasps the slug and now that the slot I29 in the back face plate of the coin passage assembly I20 is in line with the coin exit slot II9, instead of passing through into the mechanism the, slug is held firmly against the magnet to initiate return of the same to the inlet opening. As the coin receiver retracts in a clockwise direction when pressure against it is released, the coin passage mechanism is again depressed by action against cam surface I33 so that the slug carried in. the slot between the coin passage plates I is moved back and away from the magnet. After the coin receiver 33 returns with shaft 34 to normal position, at Which slot I28 in front face plate I23 once more is aligned with coin entrance slot II8, the slug is discharged from the coin receiver 33 through the latter slot. The gravity discharge of slugs through slot H0 and of genuine coins through slot I I9 conveniently is achieved by construction of the meter to ensure that the coin passage fioor between plates I25 is carried to neutral gravity feeding position somewhere intermediate normal and fully depressed positions of the tiltable receiver, yet is tilted toward slot H8 in normal position of the receiver and toward slot IIS when the receiver is in fully depressed position. When nickels or pennies are deposited, being non-ferrous, they are not held by magnet I32 on the feed stroke and thus are allowed to pass through coin exit slot I I9 into the coin slide to set the meter timing mechanism.
