14 Claims.

Our invention relates an improvement in meters for measuring predetermined periods of time, and more particularly to coin controlled meters of this type which handle an inserted coin.

automatically, independent of the operator.

The objects of the invention are to provide a device of this class which will visibly measure the passing of a certain predetermined period of time; which is automatically rendered operable l0 aifterv the insertion of a coin of predetermined denomination, without theturning of a key'or the working of any other operably connected .exterior parts; which will allow theinsertion of more than one coin at a time and will measure the full predetermined period of time for each coin inserted; which will allow coins of smaller denomination to pass through the device freely without following the normal route of a coin of proper denomination, and without afiecting the mechanism; which will notify the inserter of a coin both audiblyand visibly when the device has commenced operation; which will visibly notify an observer when the predetermined period of time has elapsed; which will visiblynotify an observer when a slug or token, instead of a coin,

has been inserted to operate the device; which is new, novel; practical, and of utility; and, which will be efficient in accomplishing all the purposes for which it is intended. a

With these and other objects in view as will more fully appear hereinbelow, our invention consists in the construction, novel features, and combination of parts hereinafter more fully described, pointed out in the claims hereto ap- 35 pended, and illustrated in. the accompanying four-sheet drawing, of which,

Like characters of reference designate like 30 parts in all the figures.

It is understood that various changes in the form, proportion, size, shape, weight, material and other details of construction, within the scope of our invention may be resorted to without departing from the spirit or broad principle of our invention and without sacrificing any of the advantages thereof; and it is also understood that the drawings are to be interpreted as being i1lus-' trative and not restrictive.

The inventive idea involved is capable of receiv- .ing a variety of mechanical expressions only one of which, for the purpose of illustration, is shown in the accompanying drawings. Any suitable housing for the device may be provided, and we 'do not wish to limit ourselves to any particular housing. A housing I20 (Fig. 13) having two oppositely aligned windows l2l for visible display of a signal flag 28, and a small window I22 for visible display of the last coin inserted, is. preferable.

In Fig. 4 may be seen the front plate i of the gear train housing, the rear plate 2 being shown only in Fig. 5. These two plates are spaced apart 5 by spacers I, 4, 5, 6, and I, riveted to the front plate I and secured to the rear plate by nuts 6.

Still referring to Fig. 4, between the-front and rear platesare rotatably mounted: a primary drive gear 9 rotatable with a shaft I9; a gear I I rotatable with a shaft I2; a pinion II and a gear I4 both rotatable with a shaft I 6 when it turns in one direction, gear I4v being rotatable on the shaft l5 when it turns in the opposite direction; a pinion I6 and a gear I'I; both rotatable'with a shaft I 8; a pinion I9 and a gear 20 rotatable with a shaft 2|; a pinion 22 and a gear 23 rotatable with a shaft 24; and a pinion 25 and a fan 26 rotatable with a shaft 21. Theshafts are all journaled in perforations in the two main plates I and 2. These gears constitute the primary gear train the purpose of which is to provide the power to operate mechanism to be hereinafter described, which raises a flag 28 (Fig. 3) and sets an indicator 29, and performs other functions.

The power is transmitted from the primary drive gear 9 to the gears and pinions in the order named. A brake arm 52 has its inner end rigidly secured to a shaft 63 which is also journaled between the two main plates. The partial rotation of the shaft 69 raises the brake arm 52 and allows the fan 26 and all the gears in the primary train to start movement. The release of the shaft 53 allows the brake arm 52 to drop by gravity into contact with the fan 26, thus stopping the entire primary gear train. The shaft I2 limits the downward movement of brake arm 52.

A secondary gear train, the gears of which are mounted in a similar manner, operates entirely independent of the primary gear train and is composed of the following: a secondary drive gear 30 rotatable on the shaft ID; a gear 3| (Fig. 5) and a gear 32 (Fig. 4) rotatable with a shaft 33; a pinion 34 and a gear 35 rotatable with a shaft 36; a pinion 31 and a gear 39 rotatable with a shaft 39; a pinion 40 and a gear 4I rotatable with a shaft 42; a pinion 43 and an escapement wheel 44 rotatable with a shaft 46; an escapement arm 46 movable with a shaft 41; and a balance wheel 48 movable with a shaft (not shown). The power is transmitted from the main gear to each of the other gears and pinions in the order named.

Power is provided by a main spring 49 (Fig. 6) enclosed between the two drive gears 9 and 30 by by a cylindrical housing 50 which is secured to and rotates with gear 30. The outer end of the main spring 49 is attached to the housing 50 in a suitable manner and the inner end is secured to the shaft I0. The spring 49 drives these drive gears 9 and 30 in opposite directions, the gear 9 driving the primary gear train and the gear 30 driving the secondary gear train. The secondary gear train is similar to the gear train of an ordinary clock and moves the indicator 29 (Fig. 3) mounted on the shaft 33, at an average predetermined speed. .The usual hair spring 6| sur-' rounds and is attached to the balance wheel shaft (not shown) and regulates the speed of the gear train, and of the indicator 29. The secondary drive gear 30 continuously operates the secondary gear train as long as the main spring 49 is kept wound.

The winding mechanism will now be described. One end of shaft I2 (see Fig. 5) is threaded and carries a square lug 52 which fits a similar shaped recess in the end of a key, not shown. The tuming of the key rotates gear II, pinion I9, shaft I5, and ratchet gear I23 (Fig. 7) which gear is retatable with the shaft I! and is allowed to turn in one direction by the pawis 64 and II pivotally mounted on the gear I4. A spring" holds the pawls in contact with ratchet I23. Gear II is thereby allowed to rotate drive gear 9 without rota the primary gear train.

The propelling mechanism which we have described is one manner of providing power for driving the time indicator and the reset mechanism. Other power means may be used, and other arrangements of the gears in the gear train may be made, and we do not wish to be limited by this one disclosure.

The most important part of our invention will now be described. We refer to the reset mechanism, more clearly illustrated'in Fig. 3. The drive wheel 61 rotates with shaft 18 (driven by the primary gear train) which extends through plate I. The wheel 6! drives the eccentric link 68 one end of which is pivotally mounted in a suitable manner on the outside surface and near the rim of the wheel. The" other end of link 66 is pivotally attached adjacent the inner surface of the lower end 69 of a coin holder 66, which in turn is pivotally mounted near its center on the extended end of shaft I0. The upper end 6| of coin holder 69 pivotally mounts, adjacent its inner surface, one end of a connector link 92, the other end of which is pivotally mounted adjacent the inner surface and near one edge of 'a reset plate 63, which in turn is rotatable on an extension of shaft 33, and is spaced away from plate I by a spacer collar (not visible). The plate 63 and the coin holder 69 rotate in the same plane, as do the links 56 and 62.

The indicator 29 is mounted on shaft 88 outside the plate 63. It is normally moved-by the shaft 33, when it rotates, by the frictional engagement of two tri-pronged spring members 64 and 66 pressed lightly against each of its sides by nuts 66 and 61, adjustable on the threaded end of shaft 23. when the indicator is inoperative, however, the secondary gear train. continues' to rotate shaft 23 even though the indicator does not move. Thelightness of the frictional contact allows this movement of the shaft.

The indicator 29 has a short integral rearweardly extending lug 66 which is adapted to contact the lower surface of an arcuate flange 6| integral with a flag bracket II to which is secured the time measuring signal flag 26. The bracket I0 and flag 26 pivot same piece about a short shaft 12, one end of which is suitably secured to the front plate I and the other end of which is threaded to receive a nut 13, which holds the bracket in position. The bracket II also carries an integral forwardly extending flange 14 which is positioned to be contacted by the edge of plate 63 as it rotates, thus raising the flag 26 into a measuring position, as shown in Fig. 8.

A time stud I6 is threaded at one end and is adapted to be screwed into any one of a number of threaded perforations I6 located in an are near the outer edge of plate 62. The stud I6 rotates with plate 69 in the same plane as thatin which the indicator 29 rotates. The stud is adapted to contact the edge of and move the indicator 29 as the plate 62 moves, thus setting the indicator with relation to the flag 26. Fig. 3 shows the plate 63 at its maximum of clockwise movement. The stud I5 is in the 60 minute perforation and has therefore set the indicator to measure a full 60 minute period. If it is desired to measure only a minute period, the stud I6 is set in the 30 gear I4,oranyoftl'ieothergearsin minute perforation, in which case-the maximum clockwise movement of the plate 88 causes the stud 15 to move the indicator 28 to the 30 minute marking on the flag.

The reset mechanism is propelled, as previously mentioned, by the primary gear train. A starter. link H is securely fastened on the extended end of shaft 58 by a set screw 11. Its opposite end carries a trigger pin 18, the ends of which extend on either side of the link, the forwardly extending end adapted to be contacted by a coin, in a manner later to be described. and to thereby start the primary gear train by slightly raising the brake arm 52, thus allowing the brake fan 28 to rotate.

A coin ejector 18 is secured to one end of a shaft 88 which is journaled in perforations in the two main plates I and 2, and whose opposite end extends beyond the rear plate 2 and carries a bell clapper 8I (see Fig. 5) adjustable on the shaft witha set screw 82. The ejector 18 (Fi 3) is spaced away from the plate I by an integral spacer collar H8, which surrounds the shaft 88 between the ejector 18 and the front plate I. A coil spring 83 surrounds the spacer collar and has one of its ends anchored to a post 88 and its other end anchored to the lower end of the elector 18. The spring tends to hold the ejector 18 in the position shown in Fig. 3. The elector 18 has a rearwardly extending lug 88 which extends almost to the wheel 51 and is adapted to be contacted bythe link 58 as it is moved by the wheel. The ejector 18also has an integral forwardly extending lug 85, the edge of which is adapted to contact a coin in a manner later to be described. The post 88 limits the counterclockwise movement of the ejector 18.

For guiding the coin to its operative pos tion with relation to the mechanism we prov de an inner guide plate 88 (Figs. 1, 2. 9. l8 and 11) to i which is riveted an edge guide plate 81. which also serves as a spacer to space an outer gu de plate 88 (Fig. 1 only) away from plate 88 so that a coin. Ild may pass freely therebetween. Hollow spacer posts 88. 9| and 92 (Figs. 1. 2. and 3) fit suitably located perforations (not numbered) in the guide plate and serve to space the plate away from the reset mechanism.,allowing it free movement. The inner ends of said spacer posts screw into the front plate I. The spacer p sts 88 and SI also extend through the outer plate 88. and screws 83 and 84 (Fig. 1) screw into the ends of posts 88 and Si to firmly hold the two plates in position. Screw (Fig. 1) likewise screws down tightly on plate 88. A secondary screw 88 screws into aligned threaded perforations in the plates 88, 81 and 85.

A plurality of spaced guide lugs 81. 88. 88. I88, I8I, I82, and I83 all secured to plate 88, as well as the inner edge of plate 81, serve to guide the downward travel of a coin. The plate 88 has an inwardly flared portion I88 (Figs. 1, 2 and 12) which is adapted to be positioned adjacent a coin slot in the housing I28 which completely houses the device. This flared edge I84 serves to guide a coin from the outer coin slot to the space between the two plates 86 and 88.

The plate 88 when in operative position lies in the same plane as that in which the trigger pin 18, the lug 85, and a forwardly extending coin pin I I1,.carried by the coin holder 68, move. To provide for free movement of pin 18 and pin II1 an arcuate through slot I85 and a smaller through cross slot I88 are provided in the plate 88. To accommodate the free movement of lug 85 an arcuate notch I81 is provided in the lower edge of plate 88. The pins 18 and III and the lug 85 extend practically to the inner surface of plate 88.

so that a coin between the two plates 88 and 88 would necessarily have to be contacted by these members.

Referring to Fig. 5. a gong H8 is removably secured to the rear plate 2 and encloses the clapper 8|, which is adapted to normally contact the outer rim of the gong.

Referring to Fig. 12 we disclose one method of preventing a coin from passing into operative relation with the reset mechanism, while the time measuring mechanism is still operating due to the action of a previously inserted coin. A member I88 has an arcuate slot I88 to accommodate the movement of" a pin II8 which is secured to and travels with the indicator 28. It also has a slot III which accommodates a pin II2 which is secured to the plate 88. The slot III limits the longitudinal movement of the member I88 in either direction. A spring 8 suitably mounted on the plate 88 normally holds the member I88 at its limit of movement toward the plate 81. In this position the end of member I88 is sumciently near the plate 81 to prevent a coin from passing edgewise between the two. As the indicator 28 nears its inoperative position (as in Fig. 2) the pin II8 contacts the end of the slot I88 and moves the member I88 away from plate 81 allowing the coin to pass downward by gravity. The member I88 is held in this position against the tension of spring II8 until the mechanism is again set in operation by the passing of another coin into operative relation with the mechanism.

Operation In Fig. 2 the various parts are shown in their inoperative positions. A coin Ill dropped into.

the outer coin slot in the housing I28 is guided by flange I88 to the space between the two plates 88 and 88, whence it travels by gravity along the path defined by lugs 81, 88, 88 and I88 and the inner edge of plate 81 to the position shown by the heavy dotted lines in Fig. 1, where it contacts the trigger pin 18 and the pin 1. The weight of the coin causes it to act as a wedge between the inner edge of plate 81 and the pin", thus moving the pin 18 and the starter link 1I. Shaft 88 (not visible in Flgs. 1 and 2) is partially rotated by this movement, and raises arm 52, allowing the fan 28 to rotate, which in turn allows the primary gear train to begin operation. Shaft I8 rotates wheel 51 which in turn moves link 58. Link 58 contacts lug 88 and moves ejector 18 from the position in Fig. 2 to the position shown in Fig. 1 (dotted lines). Ejector 18 rotates shaft 88 which moves the clapper 8| (Fig. 5) from-the position indicated by the letter A to the position indicated by the letter B.

The link 58 (Fig. 2) partially rotates the coin holder 88 until its arcuate edge passes the inwardly extending end of the pin 18. The pin 18 'is thereby preventedfrom returning to its normal inoperative position until the coin holder 88 returns to its normal position, as in Fig. 2, at which time the pin 18 seats in the notch in the coin The rotation of the coin holder 88 moves the connector link 82, which in turn rotates plate 83; the forward portion of its arcuate edge contacts the flange" moving the bracket and flag from As the plate OI rotates, the stud II eontactsthe edge of indicator 2! moving it in a clockwise direction and into a position of visibility thrown said windows (III). The lug ll passesunden neath the flange it in a position to support the bracket and flag.

, As the reset mechanism continues in its movement the various parts move to the positions shown in Fig. 8 which is the-limit of their movement in one direction. The stud II has moved the indicatorto the 60 minute mark'on the ilag. As the rotation of wheel ll continues all the other parts return to their inoperative positions (Fig. 2) at which time the brake arm I! contacts the Ian 28 and stops the primary gear train. The bracket II and flag 2! are held'in the position shown in Fig. 3 by the lug It. The frictional contact of the flange I on lug I is so small that the movemerit of the indicator II is not affected.

The secondary gear train (which runs continually) now moves the indicator counterclockwise across the marked face of the flag, and an ob-' server can tell at a glance the proportion o! the predetermined time which has elapsed. Needless to say, the secondary gear train is so timed as to move the indicator from the point indicated by the numeral 60 on the flag to the point indicated by the numeral in a period oi 60 minutes.

As the wheel 51 rotates (Fig. 1), the lug 84 is released from its contact with link II and the spring 83 returns the ejector II to its position shown in Fig. 2. This return movement is rapid, and causes the clapper II (Fig. 5) to move rapidly from its position B tothe posltion A'-, and to strike the gong II8 sharply, ringing the gong, and thus audibly notifying the operator that the device is in operation. The movingotthe flag indicator into indicating position serves as a visible signal that the device is in operati since in this position they are both visible through the windows I2I of said housing.

when the predetermined time has elapsed, the lug 68 passes out from under the flag It, and allows the bracket 10 and flag 28 to drop away from the windows III in said housing to the position shown in Fig. 2. This movement is limited by the flange 6! contacting a spacer collar (not visible in the drawings) integral with the starter v link II. and into which the set screw 11 screws (Fig. 3). The counterclockwise movement of the indicator 29 is limited by contact with the shaft 12, on which the flag bracket I0 pivots.

Now reierring'more particularly to Figs. 9, l0 and 11, we will trace the travel of the coin I II and of the previously inserted coin Hi. We have already traced the movement of the coin to the position shown in Fig; 9, at which point its movement is stopped by coin pin I I1 carried by the coin holder 6!. At this point the edge of the coin has contacted trigger pin It and has moved starter link II, allowing the primary gear train to start. As the reset mechanism moves, coin pin III moves to the position shown in Fig. 10, the trigger -II being held away from the edge of the coin by the arcuate edge of coin holder 60, as previously described. From this point the pin IIl moves to the position shown in Fig. 11 and the coin Ill passes by gravity downward past the pin I8 until its lower edge strikes the guide lug I03. As the pin I I1 returns to its .normal position (Fig. 9) it"pushes the coin past the lug III, and

the coin edge contacts the ejector lug ll. The coin is heldbetween the lug II and the lug I, as inHgJLandlnthlspositionlsvisibletin'oug'ha small suitably located window'ln the housing (not shown).
