raErAYMENr GAS-METER.
25, 1916. Serial No. 80,814.
To all whom it may concern:
Be it known that I, NILS DAVID NIL-SON, a subject of the Kin of Sweden residing at Stockholm, in the kingdom of weden, have invented a new and useful Improvement in Prepayment Gas-Meters, of which the following is a specification.
This application is a division from my copending application Serial No. 808167, filed on December 22, 1913.
My present invention'refers to a prepay ment gas meter and has for its ob'ect to provide simple and effective means or moving a member of the gas valve operating mecha nism in one direction according to the number of coins deposited in a coin controlled apparatus cooperating with the same, and for gradually retrieving the said member as the gasis consumed.
The invention is broadly characterized by thisthat a, gear receiving intermittent ro- -tary.motion in one directlon from the. coin controlled apparatus, is formed as a nut for aserew journaled in a frame havmg an operative connection with the gas valve. On
the said screw a worm-wheel is slidingly but not rotatably mounted, which worm-wheel casing 1.
engages with a worm driven from .a shaft of the main gas meter.
The accompanying drawing illustrates one form of the invention.
Figure 1 is a front elevation of the appsratus, a portion of the cover being removed.
Fig. 2 is a sectional side view.
Fig. 3 is a top view of a horizontalsection.
and a portion of the gearing viewed from above. a
- All arts of the apparatus with the exception 0 the valve for the opening and closing of the gas-piping are arranged within the The gas valve 2 is located in a box-like section 3 at the rca r of the casing, mto wlnch section the main-pipe 4 opens and from.
which the pipe 5 leads to the main gasmeter, said pipe. bclng conlroll'cd by means of theralvc 2. The drlvmg mmrhanlsm of the main ,Q'flS lllllll is connected to the shaft 6 (Fig. 3). which in horcilnzftcr described manner is gcarcd to tho mechanism of the prepayment mcter.
Tho coin controlled mechanism for operelosing the gas valve 2 may suitably Fig. 4 shows the coin controlled apparatus ating the meter mechanism for openin and of the construction described and claimed in my co-pending U. S. Patent Application Sej rial N 0. 808,167, and which consists, mainly, of a cylindrical drum 7 adapted to turn by means of a pivot 8 in a stationary bottom plate 9 and provided with a cover or cross-- plece 9 to which is secured the spindle 10,
which estends through the casing 1 and on the pro ecting part carries a handle 11 of suitable shape b means of which thedrum 7 may be-turne To the under side of the cover or cross-piece 9 is ivoted one endof a lever 12, the other en of which is vided with a finger 13 which re ects through a slot 14 in' the drum.- W en the drum is in normal position as shown in Figs.
1, 2, and 3 the slot. 14 will be right oppos a similarly shaped slot 15 in the front side of the casing 1. The coin 16 can now be introduced mto the drum from outside through both openings. Whenthe drum'is turned b means of .the handl'e'll, the coin IS brou t along and remains standing on edge. n the pathv which the coin has to pass during the turning of the drum, are coated two arc-shaped and concentric ribs or guides 20projectin .from the bottom 9, Which increase in heig t from .the starting position ofthe coin, as shown in Fig.2, unto a radial lot 21 in the bottom 9. As the coin is in night along at the mo'vement of the drum 7, 1t slides on the two ribs 20, and is in this manner elevated as the ribs increase in height, and consequentl the end of the lever 12 provided with the 'nger 13 isjraised. The finger 13 is thereby brought in such position that during the last period of the turning of the drum it will engage with and turn an intermittent gear-22, of the shape shown in Fig. 4. This intermittent geal" Specification 01 r I Q E- Patented July 31., 1917. Original-application fi led December 22, 1918, Serial No. 808,167. 'Dividedand this application filed February :nnsm is arranged in the following manner;
The main part consists of a screw 23, the ends nl' winch are pivoted in a frame 24. From this latter extends a rigidly, secured arm 25 Willl'il slides up and down on a fixed gulde 26, and a rack 27 meshing with a pin- 'oe...-. f lon sumu to t n s in t of an index hand 25). The huh 2;! of the above mentioned intcrmitlrnl gear 212 is shaped as a nut, fitting gea i- 22Ione step, theg'ear, which also serves i force the screw to turn, on account of the near its lowerln into the main g' supported from a fixed bracket 30 (Fig. 2), and has above it a worm -wheel 31.
,This latter wheel which is supported from above by means of another bracket '32 (Figs.
1 and 2), does not mesh with the threads of the sgrrewflli, butgthe screw can slide-longs tiidihally throngh the worm-wheel 3 1.
