RICHARD WARD COIN-CONTROLLED ELECTRICITY mn'rnn'.

Application filed December 8, 1926, Serial No. 153 -,418, and 1:n Great Britain February '6, 1926.

This invention relates to coin-operated mechanisms, more particularly for use in connection with prepayment meters for electricity and the like.

The present invention consists in the coincontrolled electricity meter hereinafter de scribed and more particularly pointed out in the claims.

Referring to the accompanying draw- .1ngs:

Figure 1 is a front view with removed;

Figure 2 is a side view with a portion of the frame removed; v

Figure 8 is a view of Figure 2 looking in the direction of arrow;

Figure 4 is a detail.

In carrying the invention into effect aca portion cording to the form illustrated'by way of designed to be operated. The price plate is locked in varying angular positions, according to the price ruling of the commodity in question, by means of a stop, hprovided on the frame, 1, which engages with indentations or teeth on the periphery of the price plate. This stop, 41, can be removed and the plate rotated, or conversely the price plate can be lifted up so that the teeth clear the stop, rotated and replaced with the stop engaging another tooth. The price plate, 2, is held from being disengaged from the stop by means of ring, 5, fastened to the frame, 1, by suitable bolts or the like secured so that no unauthorized person can change the plate. Mounted rotatably on the price plate is another plate, 6, having a slot, 7, for the coin of the same size as or larger than the slot, 3, in the price plate.

The price plate is provided in the centre with a hole through which passes the handle or knob, 8, which is securely fixed to the plate, 6. The knob, 8, is provided with a flange so that it cannot pass through the hole in the price plate. The plate, 6, can thus be rotated relatively to the price plate. A projecting portion, 9, is provided in the plate, 6, which comes in contact with a stop, 10, on the back of the price plate in which position the slots, 3

insertion of the coin. Immediatelybehind the slot, 7, is provided a pocket, 11, for the coin consisting of a U-shaped metal chamber, 12, the'ends of the arms being flanged 'over to form feet, 13,-which are secured to the plate, 6. The coin pocket'may be attached by any other suitable means to the plate, 6..

Over the end of the coin pocket, which is open, a catch, 14, is provided to prevent the coin from escaping consisting of a right angled or L-shaped piece of sheet metal,- the short end of which covers'theopening and the long end of which is securedto' a Hat spring, 15, fastened to the side of the coin'pocket to keep the coin pocket losed. This catch is operated .in'the extreme position of travel by a stop, 16, against which it comes in contact so as to open thejpbcket' and allow the coin to be ejected'while the projection, 17, makes contact with the coin pocket itself and prevents further rotation. This stop, 16, is mounted in a fixed upon the frame of the mechanism.

In the coin pocket ismounted a lever, 18, (Figure 4) the pivotal point of which is formed by the projection, 19, which slides between two pins, 20, 20,in said pocket in a radialdirection either at right-angles or slightly inclined to the axis'of rotation of said pocket and pivots about the pln 20. The pivotal point may be situated'at the bottom of the U-shaped pocket or in any other suitable position. The free'endof the, lever projects through the open end of the pocket awayfrom the end in which the coin is placed and is provided "with a projection, 21, which s adapted to engage in a toothed or notched wheel, 22, when the coin is inserted. A pawl (not shown) is provided to prevent the wheel, 22, from rotatingin one direction. The projection, 21, on the'lever may be so arranged that rotation of the lever about its pivotal point brings the projection up against the toothed or notched wheel at a d stance less than the bottom of the teeth from the centre of said wheel. In this manner the projection on the lever will not enter the teeth or notches in any position unless a radial motion is given to said projection which then allows it to enter the notch or tooth corresponding to its position.

On or near the projection, 21, of the lever is mounted a pin, 23, to which is attached a. spring, 24. The other endof the spring is attached to a suitable pin, 25, or the like. This pin is situated so as to be out of alignment with the line joining the end of the lever and the point about which the lever pivots. In this manner the spring tends always to pull the lever towards the end in which the coin is inserted and also rotates the lever about its pivotal point so that the projection is held out of engagement with the teeth or notches in the wheel, 22, when a coin is not in position in the coin pocket.

This s ring also acts upon the lever, 18, so that irectly the catch, 14, at the end of the coin pocket is displaced the spring presses the coin and thus positively ejects it from the pocket.

The end of the lever in contact with the coin is provided with a rojection, 26, of such a shape that on insertion of the coin the leveris made first to rotate about its pivotal point against the force of the spring and afterwards to slide in a radial direction lever to engage in the teeth or notches, until the coin has been inserted a sufficient amount when the lever sprin s back and draws the coinicompletely into the pocket by means of the inclined edge, 27.

The price plate, 2, may be so arranged that the projection, 21, on the lever will not enter a tooth or notch on the plate, 22, when the coin is inserted until the handle has been turned sufiiciently to completely close the slot, 7, through which the coin has been inserted.

When the end, 21, of the lever is opposite a tooth the rotary motion continues, due to the spring, 24, and the projection enters the slot or tooth in the wheel.

The centre of the coin pocket may be provided with a small trunnion, 28, which fits into the centre of the toothed or notched wheel, 22, so as to form a bearing about which the coin pocket rotates.

The toothed or notched wheel is attached to the usual differential mechanism or the like which controls the supply and may cut it off after the predetermined amount has been supplied.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a coin-controlled electric meter, the combination comprising a frame, a pricechange plate rotatably mounted on said frame and having a coin insertion slot therein, means for securing said plate in varying angular positions with respect to said frame, a coin pocket rotatably mounted upon said price-change plate, a lever rotatably mounted within said coin pocket and having a projection thereon, two pin members mounted upon said coin pocket and 'co-acting with said projection so as to allow said lever to slide and rotate, and means attached to said coin pocket for retaining the coin in the pocket during the required rotation of said pocket, as set forth.

2. In a coin-controlled electric meter, the combination comprising a frame, a pricechange plate rotatably mounted on said frame, and having a coin insertion slot therein, means for securing said plate in varying angular positions with respect to said frame, a coin pocket rotatably mounted upon said price-change plate, a lever slidably mounted within said coin pocket and having two projections thereon, two pin members mounted upon said coin pocket and co-acting with-one of said projections so as to allow said lever to slide and rotate, the other said projection co-acting with the coin to draw it through the said slot, and means attached to said coin pocket for retaining the coin in the pocket during the required rotation of the said pocket, as set forth.

In testimony whereof I have signed my name to this specification.

RICHARD WARD JOLLY.
