4 Claims.

The present invention relates to parking meters and has for an object the provision of a simple coin controlled mechanism arranged for selective adaptation as regards resetting of the mechanisrn.

Another object of the invention is to provide a coin controlled, manually set mechanism wherein the handle is locked against movement except when a coin is properly positioned in the mechanlsm.

A further object of the invention is to provide a simple and direct intercontrol between an indicator, a violation signal, a release for a previously deposited coin, and a counter for coins to assure perfect functioning or these parts whenever the mechanism is manually set after deposit of a proper coin.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fi 1 is an elevational view or the mechanism of the invention mounted in the removable casing section, the violation signal raised and the escapement brake mechanism removed, said removal casing section being shown in position on the bottom portion of the complementary fixed, post-mounted casing section, the latter being shown in cross-section.

Fig. 2 is a view taken on line 2-2 of Fig. 1, the escapement brake mechanism being shown in dotted lines.

Fig. 3 is a fragmental elevational view of the parts of Fig. 1 with the mechanism in running position and the violation signal lowered.

Fig. 4 is an enlarged fragmental view taken on line 4-4 of Fig. 2.

Fig. 5 is a view taken on line 5-5 of Fig. 4'.

Fig. 6 is a view taken on line 6-6 of Fig. 4.

Fig. 7 is a view taken on line 1--1 of Fig. 4.

Fig. 8 is a perspective view of an adjustable hub forming a detail of the invention.

Fig. 9 is a view taken on line 9-9 of Fig. 5 showing the adjustable hub arranged to permit resetting of the mechanism at any time.

Fi 10 is a view similar to Fig. 9 but having the adjustable hub arranged to permit resetting of the mechanism only upon completion of the previously initiated cycle of operation.

Fig. 11 is a view taken on line lill of Fig. 10.

Fig. 12 is an enlarged fragmental view of the inside face of the fixed casing section with the locking screws in position and the control plate in inoperative position.

Fig. 13 is an enlarged rear elevational view showing the mechanism of the meter detached from the removable casing section.

The meter of the invention provides ready accessibility of the mechanism and simplicity of construction. The tubular top end of a suitable standard or post l5 has diametrically opposed bores it near the top thereof to provide for the simple, foolproof, and invisible connection of the parking meter casing thereto.

The casing for the meter comprises two sections i1 and i8 having a complementary tongue and groove joint. which forms a vertical parting line around the sides and top, as indicated at 19, in Fig. 2. Section II has a horizontal bottom edge I10 which seats on the top of a reduced portion I of the fixed casing section l8. Portion I89 terminates in an integral tubular sleeve 25 at its bottom. The portion I 80 is downwardly cut away for a distance from its top edge and has a hinged door 33 at its bottom which serves to close this cut-away opening. the top edge or the door 'meeting the bottom edge of casing section ll. The sleeve 20 serves to slidably receive the top or post IS. A spider 2! is fixed interiorly of sleeve 20 and has a bolt 22 extending loosely therethrough. A bar 23 has an overall length greater than the inside diameter of post I5 and less than the outside diameter thereof. The onposite ends of the bar may be entered in the opposed bores IS in post I 5, prior to seating the sleeve 20 of casing section l8 on the post, by diagonally inclining the bar 23 and passing one end thereof entirely through one of the bores I from the open top interior of the post. The other end oi! said bar 23 may then be lowered inside the post and the alignment with the opposite bore l6, whereupon said latter end of the bar is entered into the last mentioned bore It. The sleeve 20 of the fixed casing section I8 is then lowered over and seated on the post in the position shown ni Fig. 1 so that the perforations are concealed and the bar 23 is substantially centered on a diameter of the post and sleeve and cannot be removed when the parts are in this position. Bar 23 has a threaded perforation 24 on its longitudinal axis at one side of its longitudinal center (see Fig. 1) to receive bolt 22. When bolt 22 is drawn tight, the bar 23 being substantially centered an eccentric invisible strong connection is efiected between the post l5 and casing section i 8.

As shown best in Fig. 2, section I1 is removably secured to section l8 by a pair of tie bar assemblies 49 and 5| each consisting of a member 25 having an axial threaded bore at each end. Headless screws 26 each have one end engaged in the interior wall of easing section II and the top and restricted at the bottom (see especially I Fig. 12). When the plate 38 is pulled down, the

, angular shank section of each lock screw 21 may turn freely in the enlarged upper part of slot 32.

When the screws 21 are tightened and holding the casing sections together, the plate 80 is pushed up from the inside of the casing and the restricted lower part of slots 32 precludes turning of screws 21.

All access to plate 30 and also to the bolt 22 is by way of the openin ln reduced portion I80 controlled by hinged door 33 having a key controlled lock 34. Any suitable cup or coin box, such as 35, is removably seated on spider 2| within the portion I80 of casing section 18 and it is also accessible through door 33.

The casing sections l1 and I8 together form a restricted top in which are opposed windows W through which an indicator and a violation si nal are visible from either side of the casing. All of the operating mechanism of the invention is bodily supported on casing section II. The screws I 21 may be removed when plate 30 is in the posi-' are interchangeable on any others of the fixedly v mounted casing sections I8.

Referring now to the mechanism of the meter, removable casing section I! carries an operating handle 38 (see Fig. 5). A flanged hub 35 on casing section II houses a coil spring 3'! which has one of its ends anchored in said hub. Operatin handle 38 has an overhanging flange 39 which rides freely on the outside of hub 38, while a central stud 40 passes through the center of hub 38 and the spring 31 to the inside of the casing where the squared end 4| of the stud enters a complementary bore in hub 42 of a pusher segment 43. Spring 31 is anchored in hub 42 and urges the handle member in a counterclockwise direction. A countersunk screw 44 fixes pusher 43 on stud 40. The pusher segment has an armate flange 45 with an end 46 and a lug 41 on the free edge of said flange at the opposite end of The remainder of the operating mechanism is mounted on a back plate 48 removably secured to the inside face of easing section ll. Back plate 48 is secured by tie bars 49 and 5! and screw 50 entering suitably located tapped bosses 52, on the inner face of casing section [1, and'has an aperture 53 (see Fig. 13), so located and so shaped that. the arcuate flange'45 of pusher 43 may freely operate therein. A coin slot structure, which forms the subject matter of a co-pending application, Serial No. 282,646, flied of even date herewith but now abandoned, includes an exterior projection 54 on casing section I! through which coins are entered horizontally, and an interior chamber 55 wherein the inserted coin is turned to roll edgewise down a chute or tube 58 to a position within therange of the flange 45 of pusher 43.

' An odd shaped member 51 has on one face a pair of edge flanges 518 and 5'" which are brazed or otherwise suitably attached to the rear face of plate 48 (see Fi 18). The upper curved part of flange 510 defines part of a curved coin way 58, while the lower part of flange 510 and the flange 5H define between them a lower coin way 59 communicating with said way 58. Member 51 is cut out at 60 to render visible a coin which is retained in the way 59 by means hereinafter described. A glazed sight opening 8| is disposed in casing section l opposite said cut-out 50 (see- The-member 51 extends upwardly and partly across aperture 53 and has a bore 82 which is coaxial with stud 40 of the operating handle. Concentric to bore 62 is a slot 63' in member 51 which permits arcuate flange 45 of the pusher segment to be moved through slightly more than onefourth of a turn against a limit stop formed by a boss 64 on the inside of casing section II. The pusher segment is ncirmally spring-urged away from stop 84 and against a stop boss 65. On opposite sides of plate 48 is a pair of forwardly projecting spacer posts 61 which receive the notched corners of a leaf 88 that carries a suitably housed escapement brake mechanism 59. Pivoted on stud 10 which is 'flxed in the face of plate '48 is a lever H which serves as a latch and a coin arrester. I Lever H is longer and heavier below its pivot so that its top end 72 is normally urged into the path of flange 45 on the pusher segment to permit very little movement of handle 38 when there is no proper coin in place for setting the meter. I

A pin 13 on lever ll normally projects across the coin way so that a' coin entering the coin slot will come to rest thereon, as shown in dotted lines in Fig. 9. If the outside handle 38 is now turned, the end of flange 45 in the pusher segment presses on the coin which pushes pin 13 away,

. thus rocking the lever H on its pivot and allowing the coin to be pushed beyond the control of said pin '13.

A stop 14 limits the swing of lever II in one direction and also retains said lever in the position shown in Fig. 9 wherein a rearwardly turned extension 15 on the lever H engages the operating arm I6 of a coin counter 'Il whenever the lever is rocked by the passage of a coin. Secured on operating arm 15 is an L-shaped coin stop flnger 18 which supports the last coin opposite the sight opening and swings transversely aside to release the coin whenever the counter mechanism is actuated by the succeeding coin. It should be noted that one wall of vertical coin way 59 is notched out at '19 to permit the transverse swing of the end of coin stop finger l8.

A simple and inexpensive flat stamping, indicated generally as 8|), performs a number of vital functions in the meter of the present invention (see Fig. l). Stamping 80 and the hereinafter described parts connected thereto may be conveniently termed a rockable indicator unit. Member 80 has an indicator hand 8| formed at one end and at the opposite end there is formed a toothed gear segment 82. A cam finger 83 is formed by a lateral extension on the member 88 and inwardly therefrom are a plurality of threaded perforations 84 arranged concentrically with and opposite gear teeth 82. A stud shaft body 85 extends fixedly through member 88 concentrically or toothed segment 82 and perforations 84 and is supported rockably on the shouldered end 88 in the bore 82 in plate 51 (see Fi 11). An adjustable hub 81 (see Fig. 8) has adjacent its periphery two internally threaded bosses 88 and 88, either of which may be engaged by a screw 98 that passes througha fixed location in member 88 (set: also Figs. 4 and 5). Hub 8'! has a flange 8| which serves as a complement to the arcuate portion of coin way 58. The stud 85 between flange 9| and the member 51 defines an edge of the arcuate portion of the coin way of which the upper curved portion of flange 518 defines the opposed edge. An arcuate shoulder segment 82 on hub 81 may be arranged to block this curved portion of coin way 59 at times (see Figs. 5, 9, 10, 11 and 13). The shoulder segment 92 assumes a selected position which is determined by the attachment of hub 81 by screw 98 in one of the threadedly bored bosses 88 or 89. When the screw passes through stamping member 80 and into boss 88 of hub 81, the segment 92 which is disposed in the plane of coin way 58 does not move far enough during the limited rocking movement of member 88 to block the passage of coins from 58 into the arcuate coin way defined by member 58.

When screw 98 enters boss 88, the segment 92 is so related to the member 88 as to block such passage of coins except when the indicator 8| has reached the zero position as shown in Fig. 1, via, until the indicator has completed a cycle of operation. The foregoing adjustments thus determine whether the mechanism may be reset at any time or only after a previous cycle of operation is concluded. When the device is arranged to receive a plurality of coins at one time with the assured operation of the device through one complete cycle for each deposited coin. a motorist may deposit one or more coins and set the device in operation with the first coin. The traffic officer, or any other person, may reset the device after the parking period has expired if another coin remains available.

Parallel to the leaf plate Iili'is a transverse support 83 which is secured to the ends of posts 8'! and the auxiliary posts 94 by screws 85 and an extension post 88. A bore 8? serves to journal a reduced end 98 of stud shaft 85 upon the free projecting end of which is a hub or barrel 99 that supports the flat coiled power spring Hill. The free end of spring I88 is hooked over extension 88 and serves to at all times urge stud shaft 85 and the stamping 88 toward the zero position of indicator hand 8! as shown in Fig. l. A pinion E8! on the escapement brake mechanism 88 meshes with the toothed segment 82 of stamping 88 to provide for a regulated rate of return movement of the indicator 8i when said spring tilt is wound. a

From the foregoing description, it will be noted that when no proper coin is in position in the device, the setting handle 38 is locked against rotary movement by the abutment of the end 46 of flange 45 upon the top end 72 of lever II and the mechanism cannot be set. When the proper coin enters and rests on pin 33, the pusher segment 43 urges the coin against pin 73 so that the lever ll rocks on it pivot 78, removes pin 13 from the path of the coin and allows the pusher segment to operate under continued manual pressure on handle 38 and move the coin through the arcuate passage or coin way 5'! until pusher segment 43 reaches limit stop 84 and the coin drops into vertical way 58. During this rocking movement of lever 1|, the counter 11 was actuated and arm 18 moved out of notch 18 to drop the previously arrested coin and returned to its position to arrest the coin which Just served to enable operation of the handle 38.

As the pusher segment was turned, the finger 41 engaged the projecting screw stud I82 which is adjustably positionable in any of perforations 84 in member 88 and rocked said member on its axis and tensioned th power spring I88. It will be apparent from an inspection of Figs. 1, 4 and 6, that as stud I82 is moved to the right, as viewed in Fig. 1, or closer to the starting position of finger 41 on pusher segment 43, said stud is engaged sooner and the stamping 88 is rocked farther about its axis during the movement of said pusher segment 43 and requires a correspondingly longer time to return to zero position under the influence of spring I88 and the escapernentbrake 69. The desired parking period is thus selected by the adjustment of stud I82 in th proper perforation 84 before placing the meter into service and may be changed without difficulty by a relatively unskilled attendant.

The transverse support 83 has a vertical arm I83 upon which parallel levers I84 and I85 are pivoted as at I86. A link I87 pivoted at its end to said levers serves to retain them in parallelism, and this link has fixed thereto a violation signal I88 of suitable shape and color which is raised and lowered vertically between the windows W at the top or" the meter casing. Arm 685 has a weight member E89 fixed thereon which is raised by the weight of signal I88 whenever the weight is unrestrained. Lever E8 has a lug or pin M8 projecting into the path of cam finger 83 so that as the member 88 with its indicator 8% and said cam finger slowly returns to zero, the pin is de= pressed by said cam finger and the violation signal is caused to raise to a visible position. The arcuate lower edge of finger 8S cooperates with pin H8 in a very gradual cam action until the pin reaches the end of notch i l i whereupon continued movement of member 88 rapidly depresses the weighted end of the parallel lever and raises the violation signal Hi8 full and quickly.

The operation of the device is readily understood from the foregoing. "When a coin deposited in the coin chute comes to rest on pin 58, the edge of the coin is higher than end of lever ll hence, the pusher segment engages the coin when the exterior handle is turned. This serves to push pin it aside to permit further turning of the pusher segment which engages stud M2 in. member 88. The indicator hand 35 is thus moved away from zero and power spring E88 is simultaneously wound. The pressure of finger 83 on the weighted end'of the lever is relieved and the violation signal Hi8 lowers by gravity. The escapeinent brake 88 provides for the slow return of the indicator under the influence of the power spring and finger 83 engages the weighted end of the parallel lever system to supply the small amount of additional force required to again raise the violation signal at the completion of the cycle of operation.

What is claimed is: v

1. In a parking meter the combination of a manually rotatable pusher, a coin way disposed in part concentrically of said pusher, said coin way having a notched wall, below said concentrically curved part, the portion of the coin way opposite said notch defining a coin inspection station, an operating arm, a coin stop finger mounted on said arm swingable through said notch and normally disposed in said coin way for holding a coin in the coin way at said inspection station, a latch lever having one end normally blocking manual operation of said pusher,
