Application June 1,

8 Claims.

This invention relates to parking meters for timing and indicating the duration of parking and related periods which may be prescribed by ordinances androther regulations, and in some 5 respects is an improvement over the parking meter disclosed in copending application for United States Letters Patent, Serial No. 71,088, flied March 27, 1936.

The invention includes among its objects the m provision of a novel and an improved parking meter of the token or coin controlledtype; the

provision of such a meter which will discourage the use of spurious or counterfeit tokens or coins for the actuation of the meter; the provision of means in such a meter for holding the last controlling token or coin in view from outside the meter until another token or coin is employed for controlling the meter; for thereupon releasing the held token or coin, and for arresting N the last controlling token or coin in the exposed position; and the provision of such token or com arresting, holding, and releasing apparatus which is operable from the token or coin freed apparatus of the meter.

Other objects of the invention will become apparent from the following description which, with the accompanying drawing, exemplifies a preferred embodiment of the invention. In the drawing:

go Fig. l is a fragmentary, vertical, cross section through a parking meter embodying the features of the invention;

Fig. 2 is a fragmentary elevation of the token or coin handling apparatus, showing the novel as token or coin arrester in assembled relation to the depositing guideway;

Hg. 3 is a perspective view of the token or coin arrester and the support therefor; and

Fig. 4 is a fragmentary plan view of certain ap- 40 paratus shown in Pig. 2.

Illustrative of the invention, the drawing shows a token or coin controlled parking meter comprising a token or coin controlled clock or other timing means shown diagrammatically at I i, indi- 45 cator means l2 driven from the timing means, manually operable token or coin freed apparatus II for energizing or winding the timing means and for setting the indicator means, and a suitable casing' il in which the above mentioned 50 means and apparatus are operatively assembled as more fully described in the above identified application. It will be understood that the invention is not limited to any particular type of timing means,- indicator means, token or coin 55 freed apparatus, or casing, respectively, those shown being for convenience of illustration. 'lliey are not, therefore. described in detail. By way of explanation, it might be well to point out in connection with the illustrated parking meter that a token or coin may be inserted in an 1936, Serial No. 82,864

appropriately located receiving aperture or slot in the casing H which may be of two-part, weather resisting construction held closed by a key-operable lock i5 and having a pair of aligned sight windows it in opposite casing sides. Such an inserted token or coin will pass into a receiving guideway ll in the casing for guiding the token or coin to an operative position with respect to the token or coin freed apparatus l3.

It will be observed by reference to Fig. 2 that normally before a token or coin is delivered to the apparatus i3, one of a pair of diametrically opposite slots i8 therein cooperates with a pin or detent l9 intermediate the ends on an arm 2 i, pivoted as at 22 on a stationary guide member 22 of the apparatus i3, and with a ratchet 24 engaged by a spring urged pawl 25, for holding the apparatus it against rotation in a clockwise direction. Each slot ll being wider than the pin ii, the apparatus I3 is normally capable of limited movement in a counterclockwise direction as viewed in Fig. 2, but if no token or coin is in the apparatus it during such limited movement, the assembly is automatically returned to its normal position by the spring urged pawl 25 acting against one of a pair of enlarged teeth 2' of the ratchet '24.

When a token or coin is in the manually operable token or coin freed apparatus i3, rotation thereof in a counterclockwise direction as viewed in Fig. 2 causes the token or coin to be transferred from the outlet of the receiving guideway II to the entrance of a depositing guideway 21 at the opposite side of the apparatus II for delivery to a suitable token or coin receptacle 28. The first portion of the transferring movement of the apparatus i! as just described causes the token or coin to cam the pin I! out of the slot II to engagement on an arcute or peripheral surface 2! of the apparatus l3, whereby to free that apparatus for further rotation in the same direction. Such further rotation of the token or coin freed apparatus i3 may be continued until the next slot ll registers with the pin i9, whereupon the arm 2i moves the pin into that slot to stop the rotation of the apparatus, the spring urged pawl 25 cooperating with the next enlarged tooth 28 to position the apparatus I! for receiving another token or coin from the receiving guideway ll. At that position of the apparatus I3, the token or coin which last actuated the pin i9, drops from the apparatus into the depositing guideway 21.

, During the transfer of the token or coin from the receiving to the depositing guideway as just described, the token or coin, or some other member movable with the token or coin freed apparatus ll, engages a pin or projection Si in any one of its sockets or positions "on a gear member 33 for rotating that gear member a distance depending upon the location of the pin 2|. That gear member 33 is drivingly connected with the winding or energizing and setting means of the clock or timing means ll through a gear 34 meshing with the gear member 33 and with a gear 25. R- tation of the gear 35 winds or energizes the clock, and rotates a timing shaft 36 of the clock a variable distance depending upon the location of the pin 3| whereupon the clock is adapted to rotate the timing shaft 36 in the opposite direction for measuring time.

As shown in Fig. 1, the indicator means l2 comprises an indicator disc or other means 31 for indicating parking and related periods, visible through the sight windows 16, and a shutter or other means 38 cooperating therewith for indicating the proper and improper settings of the,

parking meter. As in the aforesaid application, the disc 31 is fixed on to rotate with the timing shaft 36, and the shutter 38 is operatively connected to the arm 2| by a link or arm 39.

Thus, when the shaft 36 is rotated by the token or coin freed apparatus I3 through the pin 3| and the gears 33, 34, and 35, the disc 31 will be rotated to a set or starting position corresponding to the particular socket 32 carrying the pin Ii. During that movement of the gears 33, 34, and 35 the clock I! is energized for driving the disc in the opposite direction for indicating the elapsed time of and the time remaining in the parking period, The token or coin in operating the pin it to free the apparatus l3 moves the pin out of the slot 18 to engagement on the surface 28, thus operating the shutter 28 through the arms 2| and 39 to conceal the faces of the disc 31 facing the respective sight windows It. The engagement between the pin l9 and the surface 29 serves to hold the shutter in that position until the disc 31 is properly set, whereupon the pin l9 registers with the other slot I8 and the shutter is lowered by any suitable means, such as that disclosed in my copending application, Serial No. 82,863, filed of even date herewith, including, as described more fully in that application, a spring 4| for yieldably urging the arm 2| in a direction to lower the shutter, and a finger 42 on the arm 2| for successive engagement by diametrically opposite pins 43 on the apparatus I 3 to move the arm 2! in a. direction for lowering the shutter upon each complete setting of the disc 31.

In token or coin controlled parking meters, it is important to prevent or at least to discourage the use of counterfeit or spurious tokens or coins. To accomplish that purpose in accordance with the objects of the invention, I provide means for exposing to view the token-or coin last employed to release the token or coin freed apparatus, means for arresting that token or coin in the exposed position after it has freed the apparatus 12, means for holding the token or coin in that arrested position until another token or coin has freed the token or coin freed apparatus [3, means for positively moving the token or coin arresting and holding means to release the token or coin when a subsequent token or coin is employedto free the apparatus l3, and means for positively returning the arresting'means to itsarresting position in time to arrest the subsequent token orcoin in its exposed position. Thus each token or coin employed to free the apparatus I3 is exposed to view from outside the casing until thenext token or coin functions to free that apparatus.

Accordingly, the opposite walls of the depositing guideway 21 are provided with aligned apertures 44 which are aligned with a pair of sight windows 45 in opposite walls of the casing l4. Hie

rear wall of the guideway 21, as shown in Fig. 3, is preferably in the form of a plate 44 having the aperture 44 at its lower end and having an aperture 41 at its upper end to facilitate mounting the plate 46 on a hub portion 44 of the apparatus I 3. The plate is secured in that position by screws or other means 44, as shown in Fig. 2, and has at its upper end a transverse slot or groove II which may be covered by an angle or plate member [2 having a portion extending over the slot II and adapted to be held in that position by a screw or other attaching means54.

A rod or strip of metal, as shown in Fig. 4, is formed with a laterally extending portion 44 which is receivable in the transverse slot II and is rockable therein. From one end of the laterally extending portion 55 the rod extends downwardly along a longitudinal edge of the plate 44 and at its lower end is provided with an arcuate portion 58 extending toward the longitudinal center of the plate at a position below the aperture 44, where the rod is reformed to provide a token or coin arresting, holding, and releasing finger 51 which is I reciprocable transversely of thedepositing guideway 21 in a pair of aligned slots II in opposite walls thereof.

For moving the finger 51 in a token or coin releasing direction, the rod is formed to provide a forwardly extending portion 59 between the laterally extending portion 55 and the arcuate portion 58. From the other end of the laterally extending portion 55, the rod extends upwardly beyond the upper end of the plate 44 where it is formed laterally and forwardly to provide a portion ii for moving the finger 51 in a token or coin. arresting and holding position.

With'the plate 46 carrying the above described rod assembled as shown in Figs. 1 and 2, the laterally extending portion 55 in the slot II provides a pivot intermediate the ends of the rod, and the forwardly extending operating portions 58 and 6| are adjacent the rotatable token or coin freed apparatus I! which is provided with a pair of diametrically opposite cam surfaces 42 for operating the forwardly extending portions 58 and 6| to reciprocate the finger 41.

When the apparatus 13 is freed by a token or coin it is manually rotatable, as already described, to transfer the token or coin to the depositing guideway 21, to energize the clock H, and to set the indicator means I2. During the first portion of the rotating movement of the apparatus ll, one of the cam surfaces "engages the forwardly extending portion 5! and cams the rod about the pivot 55 in a direction to move the finger 51 outwardly of the guideway 21 whereby 'to release the token or coin previously employed to free the apparatus IS. The released token or coin is guided into the receptacle 2. by the guideway 21.

Just before the token or coin being transferred by the apparatus l3 reaches the entrance to the depositing guideway 21, the same cam surface 62 which last operated the forwardly extendinl portion 59, as just described, engages the forwardly extending portion 6| and earns the rod when the token or coin freed apparatus I3 is next released by a token or coin.

Thus the token or coin arresting, holding, and

releasing apparatus is positively operated by the token or coin freed apparatus to arrest and tohold in view the token or coin last employed for procuring the measuring and indicating of the desire to avail myself of all changes within the scope of the appended claims.
