WILLIAM L. BROWN, 0F LANSDOWNE, PENNSYLVANIA, ASSIGNOB. T0 HELME & MGILHENNY, OF PHILADELPHIA, PENNSYLVANIA, A FIRM.
PREPAYMENT-METER MECHANISM.
Specification of Letters Patent.
Application filed October 25, 1911 Serial No. 656,746.
To all whom it may concern Be it known that I, WILLIAM L. BRowN, of Lansdowne, in the county of Delaware and State of Pennsylvania, have invented a certain new and useful Improvement in Prepayment-Meter Mechanism, whereof the following is a specification, reference being had to the accompanying drawings.
' My improvement relates to coin controlled vending machines, and is particularly applicable to a gas meter to permit a valve to be manually opened upon the insertion of a coin; said valve being automatically closed by the operation of the gas meter after delivery of a quantity of gas predetermined by the number of coins inserted.
As hereinafter described, my invention "includes the combination with a valve congears; a crank arranged to open valve in open position,
trolling the passage of gas through the meter and having an operating lever with a radial slot; of a valve closing shaft, having a sun gear tight thereon, operatively connected with the meter mechanism; a valve opening shaft, in axial alinement with said valve closing shaft, operatively connected with coin controlled operating means and having another sun gear tight thereon; a planetary gear frame, loose on said valve closing shaft and carrying a screw worm; a counter shaft .journaled in said frame, having two planetary gears tight thereon and respectively engaged with said two sun and close said valve by engagement in the slot of said lever, having a gear engaging said worm, and, a cam arranged to support said when said lever is releasedby said crank; whereby opposite rotary movements of said first two shafts turn said worm in respectively opposite directions to open and close said valve, and, said index and graduations indicate the extent of movement of said valve.
My invention also includes the various novel features of construction and arrange ment hereinafter specified.
In the drawings :Figure I is a fragmentary plan sectional view of a gas meter of ordinary construction embodying my 1nvention, only the top plate of said meter being removed. Fig. II is a fragmentary vertical sectional view, taken on the line II, II, in Figs. I and III; showing the planetary gearing in position to hold said gas valve closed. Fig. IIIis a fragmentary vertical sectional view, taken on the line III, III, in Figs. I and II. .Fig'IV is a fragmentary sectional view similar to Fig. II but showing the planetary gearing in position to hold said gas valve open.
In said figures; the gas meter 1 has the v inlet 2 by which the gas enters the valve chamber 4:, from which it may pass through the meter only by way of the port 5 under control of the valve 6 carried by the arm 7 on the rock shaft 8. Said shaft projects through the stuiiing box 9 into the chamber 1 10, from which the gas is excluded, and has in the chamber 10 the lever 11 by which it may be operated. The meter mechanism beneath the floor 14 of said chamber 10 is of ordinaryconstruction, including diaphragms operatively connected with the. rock shafts 15 respectively carrying the lever arms 16 pivotally connected by the links 17 with the adjustable wrist pin 18 on the crank20.
Said crank 20 is carried on the rotary shaft 21 provided with the worm 22 engaging the worm gear 23 on the dial arbor 24, and the latter is operatively connected with suitable 'is loose on said valve closing shaft 30 and.
carries the screw worm 42, by the sleeve 43. The two counter shafts 15 which are journaled in said frame 40'each have two planetary gears 47 and 18 tight thereon and respectively engaged with said two sun gears 39 and 86. As shown in Fig. IV said valve opening shaft 38 has the gear 50 for operative connnection with the coin controlled mechanism in the casing 51, and, said sun gear 89 on said shaft 38 being held stationary during the valve closing movement ef fected by rotation of said shaft 30 by the meter mechanism, which turns the sun gear 36 in the direction of the arrow marked thereon in Fig. IV; said temporarily stationary sun gear 39 is traversed, as a rack, by
'mechanism in the dial box 26 to indicate said planetary gears 47 which thus turn said planetary gears 48 in the direction of the arrows marked thereon in Fig. II. Said worm 42 being thus turned in the direction of the arrow marked thereon in Fig. II in engagement with the gear 53 on the crank shaft 54 carrying the wrist plate 55 having the crank pin 56 engaged in the slot 57 of said valve lever 11, said valve 6 is thus closed from the position shown in Fig. IV to the position shown in Fig. II. It may be ob served that the cam 58 concentric with said shaft 54 and carried by said wrist plate 55 is cut away, as best shown in Fig. IV, so as to permit said lever 11 to approach said shaft 54 to the extent indicated in Fig. II. However, when said cam is turned in the opposite direction by the valve opening movement of said train of gearing, the surface of said cam concentric with said crank shaft 54 supports said valve lever 11 in open position, when released by said crank pin 56, as shown in Fig. IV.
The valve opening movement of the planetary gearing abovedescribed, is eflected by the coin controlled operating means in said casing 51 including the rotary coin carrier 60 having the handle 61 with the lug 62 arranged to encounter the stops 63 and 64 on said casing. Said casing 51 has the coin inlet slot 66 in which may be dropped a suitable-coin, a quarter of a dollar, when the gate bar 67 which normally closes said slot is withdrawn through the notch 68 in the flange 69 on said handle 61. When a proper coin is inserted in said slot 66 to operatively connect said valve opening shaft 38 with said handle 61, movement of said handle in the direction of the arrow marked thereon, approximately one half revolution, rotates said shaft 38 in the direction of the arrows marked thereon, so that the sun gear 39 on said shaft, turning the planetary gears 47 and 48 in the direction of the arrows marked thereon in Fig. IV, while said sun gear 36 is held relatively stationary, said gear frame 40 and the worm 42 are thus turned in the direction of the arrow marked thereon in Fig. IV toopen said valve 6. Thereupon, additional coins may be successively insorted in said slot 66 and said wrist plate 55 be thereby successively turned in the direction of the arrow marked thereon in Fig. IV until the valve 6 is opened from the position shown in Fig. II to the position shown in Fig. IV. Each prepayment for gas, for which the consumer should be credited, and dispensation of gas, for which the consumer should be debited, being manifested by respectively opposite turning movements of said shaft 54; I provide the latter with the index 7 0 tight thereon, which in the initial position of the mechanism coincides with the-stationary. radial mark 71 in the indicator casing 72, so that the amount of money or gas to the credit of the consumer at any instant may be ascertained by reference to the extent of angular displacement of said index with respect to said mark 71, which is on the dial 73.
It may be observed that although the valve opening shaft 38 and sun gear 39 are normally stationary during the rotation of the valve closing shaft 30 and its sun gear 36; the construction of the planetary gearing above described is such as to permit of the simultaneous rotation of said shafts 30 and 38 which are respectively arranged to shift the valve in opposite directions.
It is to be understood that I do not desire to limit myself to the specific type of coin controlled operating means above described or to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.
