=My invention relates to improvements in park ing meters.

important object of the invention i510 provide means to automatically reset the indi oator' to the zero or starting position, when the parked vehicle leaves the space protected by the meter,- i nth'e event that the entire parking period hasnot been consumed.

A further object of the invention is to provide 'a vehicle actuated device of the abovemen tioned character which may be applied to the conventional parking meter now in use, without materially altering the construction of the same.

"Aiurther object of the invention is to'p'ro vide resetting means which will shift the indicater slowly to avoid injury to the'mecha-nism.

other objects and advantages of the invention willbe apparent during the course of the following desoription.

In the accompanying drawings'forming a part of this application and in which like numerals are employed to designate like parts throughout same:

Figure 1 is a side elevation of a parking meter embodying myinvention,

Figure 2 is a transverse section taken on line 2-2 of Figure 6,

Figure Sis a horizontal section taken on line 3-=-3 of Figure 6,

Figure 4 is a longitudinal section taken on line 4-4 of Figure 3,

Figure 5 is a plan View ofa modified form of wheel-engaging compression element, and,

Figure 6 is a side elevation of the resetting mechanism, parts in section.

In the drawings, the numeral l9 designates a vertical casing of the parking meter, and the back platell may beremovable. Themeter casing Ill is mountedupon atubular post l2, secured to a base l3, mounted upon'the curb M.

"The operating mechanismcf the meter comrises a large gear 15, rigidly mo'uhtedhpbh a horizontal shaft 16, mounted in'suitable bearings carried by the casing, andextending ou't wardly beyond the casing front H. An indicator or" timer is iss'e'ou'red to the gear l5, Figured and travels in proximity to a stationary dial H, which is-graduated in units of time, ordinarily from- 2cm to sixty minutes. The dial I5 is held stationary within the casing and is visible through anopening in the front I 1.

-'The numeral designates 'a coin controlled disc, "mounted upon the-shaft l6 and. spacedaxi ally from the'gear l5, and connected with' the gear to turn therewith-by pins ZL'carryingspacers22. The disc 20 is equipped with the usual teeth for' coac'tion with the coin control element orelements. When the pointer is is in the starting or zero position, disc 25 is locked against turning movement, and upon the insertion of a proper coin, disc 20 is released and the pointer l8 manually turned clockwise, Figure 6, to bring it to the sixty minute position, This maybe effected by turning a handle 23 manually, and this handle is arranged exterially of the casing front I? and is secured to the shaft l6, to turn it.

When the indicator I8 is at the sixty minute position, clock works acts upon the gear 5 5 to turn it counter-clockwise, Figure 6, so that the indicator is is returned to the zero or starting position. In order that this may be accomplished, a small gear 24 engages the largegear l 5: and is mounted upon a horizontal shaft 25, journaled insuitable bearings carried by the casing I0, and held against longitudinal mcve ment upon the shaft 25. A companion gear 26 is slidable upon the shaft 25 to turn and move longitudinally with relation thereto, and a fric tion clutch element 21 is arranged between the adjacent ends of the gears 2:2 and 26. A coil spring 28 shifts the gear 25 toward the gear 24. Thegear-24 drives the gear 5 5 and gears 22 and 26 turn as a unit to move the indicator i8 toward the zero position, when the gear 26 is driven by the clock works. The clock works may include a train of gears including gear 29, a spring motor and escapement mechanism. When the indicator lBis to be shifted from the zero position to the sixty minute position, the handle 23 and shaft I6 is turned clockwise, Figure 6, and slip page will occur between the gearsZd and the gear 24 turning with respect to the gear 25, which is held-against an considerable turning movement by the clock works. When the indicator I8 is "shifted by my resetting device from the sixty minute position to the zero position, slippage also occurs at the friction clutch element 21, between the gears 24 and 23.

I have not described nor shown the coin control mechanism nor the clock works in detail, as it is unnecessary for a proper understanding of the present invention. The parking meter thu'sfar described is substantially conventional.

I provide means actuated by the wheel of the automobile to turn the gear [5 and reset the indicator l-8 to the zero position when moved therefrom. This means comprises a flexible element or cable 30 attached to the disc 20 by any suitable means. This flexible element 30 be 'arranged between the gear l5 and disc 20' and se cured to one of the pins 2|, and engaging over the other pins 2|. This flexible element extends downwardly and is attached to a vertical reciprocatory rod 3|, operating through an opening in a head 32, carried by a vertical cylinder 33, included in a dash-pot. A plunger 34 is secured to the lower end of the rod 3|, and has a large opening 35 extending through opposite ends thereof. This large opening is covered and uncovered by a flap valve 36, arranged beneath the plunger 34 and pivoted thereto at 31. This flap valve seats upwardly and has a restricted opening 38. The cylinder 33 is filled with a fluid,

of a straight length when parallel parking is permitted and will be at right angles to the curb 14. The hose 58, pipe 51 and chamber 45 are filled with a fluid, such as air, or they may be filled with a liquid, such as oil. It is thus seen that when the automobile wheel runs over the hose 58 it will be compressed and the air or fluid forced up into the chamber 45, to move the diaphragm 48 to the right, Figure 6. When diagonal parking is permitted, the L-shaped hose 59, Figure 5, will be used.

such as oil. When the plunger 34 moves upwardly,

flap valve 36 opens and the liquid may pass free- 1y through the large opening 35. When the plunger 34 moves downwardly, flap valve 35 covers large opening 35 and the liquid must then pass through the restricted opening 38 which will cause the plunger 34 to travel downwardly slowly. The cylinder 33 is held stationary by any suitable means and may be secured to the bracket 33, attached to the casing 60. The cylinder is arranged within the casing It, as shown.

The rod 3| is moved downwardly when released by a retractile coil spring 46, the upper end of which is secured to an arm 4| rigidly mounted upon the rod 3|, and its lower end secured to a lug 42, attached to the lower end of a cylinder 33.

The numeral 43 designates a stationar casing of a fluid pressure operated element, including a flexible or resilient diaphragm 44, forming a chamber 45 behind it. This diaphragm is connected with a reciprocatory plunger 45, engaging the lower end of the vertical arm 4'! of a. bellcrank lever 48, having a horizontal arm 53. The vertical arm is pivoted at 56 to swing in a vertical plane upon a support which may be mounted upon the casing 43. The resilient diaphragm 44 will bias the plunger 46 to the left or inwardly, and the bell-crank lever 43 is biased clockwise, Figure 6, by a spring 52.

Formed integral with the horizontal arm 49 is a loop 53, including a curved end 54, and sides 55, which diverge toward the curved end 54. The loop 53 is inclined upwardl toward the large or curved end 54. A stop element or ball 55 is rigidly mounted upon the rod 3|, and is adapted to be arranged above the loop 53, to engage with the diverging sides 55, and hence held against downward movement through the loop 53. When the loop 53 is swung counter-clockwise, Figures 3, 4 and 6, the large or curved end 54 is shifted toward the ball 56 and the ball will disengage diverging sides 55 and pass through the loop, so that the spring 43 may shift the rod downwardly. When the ball 56 is held above the inclined diverging sides, the downward pull upon the rod 3| tends to swing the bell-crank lever 53 clockwise, Figure 6, more securely locking the ball to the sides 55. When the ball 56 is beneath the inclined diverging sides 55, the upward movement of the ball 56 will swing the bell-crank lever counter-clockwise, and hence the diverging sides 55 will move from the ball 55 and the ball may pass through the loop to assume a position above the loop. This occurs when the handle 23 is turned clockwise to shift the indicator is to the sixty minute position.

Leading into the chamber 35 is a copper pipe 51, which may extend down through the tubular post 12, and be connected with a compressible element 58, which may be a section of rubber hose having its opposite end closed. This hose will be The operation of the apparatus is as follows: With the parts arranged as indicated in Figure '6, the indicator I8 has been shifted to the sixty minute position and the car parked in the parking space. The clock works is now turning the gear |5 counter-clockwise, Figure 6, while the rod 3| is held raised. Slack will now occur in the flexible element 30. Assuming that the automobile is driven from the parking space when the indicator l8 reaches the thirty-five minute position, as an illustration, then the wheel of the automobile will compress the hose l8 and the compressed air or fluid will be forced into the chamber 55, and the bell-crank lever 48 will be swung counter-clockwise. Ball 55 can now pass downwardl through the loop and the spring '54 will move the plunger 34 downwardly, but this movement will be slow due to the action of the dash-pot. The downward movement of the rod 3| will first take up the slack in the flexible element and then pull the flexible element to turn the wheel l5 and indicator l8 counter-clockwise, Figure 6, to bring the indicator to the zero position. This counter-clockwise turning movement is rendered possible by the friction clutch cone nection between the gears 24 and 26, and the spring is sufficiently strong to cause the clutch to slip. The plunger 35 will remain in the lowered position until the handle 23 and shaft i6 is turned clockwise, Figure 6, at which time the flexible element raises the rod 3| and the ball passes upwardly through the loop 53 and again becomes looked upon the sides above the loop.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
