COIN-CONTROLLED APPARATUS.

SPECIFICATION forming part Of Letters Patent N0. 647,849, dated April 17, 1900.

Application filed October 19, 1899. Serial No. 734,044. (No model.) A

To all whom it may concern.

I Be it known that I, FRANK A. LANGVVITH, a citizen of the United States, residing at Newark, county of Essex, State of New Jersey, have invented an Improvement in Coin-Controlled Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates to a coin-controlled device; and the object of the invention is to provide an improved article of this character; and it involves, broadly, as one of its essential features an actuatorand a member adapted tobe operated thereby, a casing having a coin-receiving slot, a shutter governing the introduction of a coin through said slot, and a locker for said actuator controlled by the shutter, and these several parts may be of any suitable kind and employed with any type of coin-controlled apparatus, though they are represented in combination with a gas-prepayment attachment for meters of the kind illustrated in Letters Patent No. 637,730, granted to Charles Luke on October 24, 1899.

In the present case the actuator consists of a knob adapted to operate a shaft from which the gas-supply mechanism is controlled, and the shutter is in the nature of a slide movable across the coin-receiving opening and adapted to throw a looking-bolt into engaging relation with the knob, so that said knob, and

consequently the shaft, cannot be rotated or turned when the bolt is set. i

In the drawings, Figure 1 is a plan view of a coin-controlled apparatus constructed in accordance with my invention and showing the same in a simple embodiment thereof, and Fig. 2 is a vertical central sectional elevation of the same.

The improvements to be hereinafter described are not limited to their application to any sort of a dispensing apparatus; but for the purpose of illustrating their peculiar functions I have represented them as applied to a prepayment attachment for gas meters wherein a coin of a certain denomination is inserted to secure the supply of a proportionate amount of gas. I

I will now proceed to briefly describe the parts of the prepayment attachment illustrated and will afterward set forth the construction and peculiar advantages of my improved mechanism.

A prepayment attachment for meters involves in its organization a valve, which is not shown; but I have illustrated a portion of the controlling or operating mechanism for opening said valve, and the same involvesin 6o its organization a spirally-grooved shaft 12,

extending substantiallycentrally through the casing C. The'face-plate of said casing is denoted by 13, and it has a central opening to receive for turning movement the substantially-cylindrical portion 14 of the knob K. The casing C, which is of cylindrical form, extends perpendicularly from theboxing or housing 13, in which certain of the operating mechanism (not shown) is inclosed.. The lefthand end of the worm-shaft passes through the coupling-wheel 16, the hub 17 of which is journaled in the opening 18 in the boxing or housing 13. Said coupling-wheel is provided with a key 19, adapted to enter the groove 20, extending longitudinally along the wormshaft, so that by advancing the wheel the shaft 12 will berotated, and through the medium of a fixed pin (not shown) adapted to fit within the spiral groove 21 the shaft will be moved to the left, whereby through the agency of intermediate mechanism (not'shown) a valve or other device can be operated.

A money-carrier is shown at M, and it has a cylindrical body portion 22 loose upon the worm-shaft, said body portion being provided with a hub or boss 23, fitted within the inner end of the cylindrical portion 14; of the turning knob K, constituting an actuator.

The money-carrier M and the knob are adapted to turn in unison, and they are 0011- veniently secured together by means of the set-screw 24. The money-carrier is provided with a flange 25, adapted to fit against the inside face of the front plate or disk 13,which is tightly fitted within the front end of the casing. It will be understood, therefore, that the knob serves to operate or advance the coin-carrier, and said coin-carrier will be connected intermittently through the intervenmo tion of a coin with the coupling-wheel 16, whereby upon rotating the knob K the wheel .1 6 will be rotated to effect the rotation of the proper denomination, as 00, the coin represv sented being a quarter and serving when introduced into the groove 27 to actuate a pawl or like device to engage the teeth 28 upon the adjacent faceof the coupling-wheel 16. The

pawl may be of any kind. That represented" is denoted by 29, audit is of a gravity type, it being pivoted, as at 30, below and to the left of its center of gravity, so that it will normally fall away from engagement with the cooperating teeth upon'the coupling-wheel.

The pawl 30 is disposed in the path of a coin and is adapted to be operated thereby to cause its working portion to enter the space between two adjacent ratchet-teeth 28, When the pawl thus, engages the teeth,-the turning of the knob, as previously stated, will result in the rotation of the worm-shaft 12.

' In practice the apparatus will be provided with means for preventing back motion'of the money-carrier and of the wheel 16.

The casing C has upon its upper side a coin-receiving slot 31, through which a coin can be passed to be entered in the groove 27 in the money-carrier M, so as to force the pawl into engagement with the cooperating ratchetteeth. When this is done, the parts will be rotated until the coin can be discharged through the slot 32, located in the casing O at apoint substantially diametrically opposite to the coin-receiving slot. 7

The apparatus represented is provided with means for stopping the money-carrier in position to receive the coin and also to discharge the same; but as these features form no part of the present invention I have deemed it unnecessary to illustrate the same.

The admission of the coin to the money- 'carrier through the slot 31 is governed by a shutter, and thismay be of any suitable char- I acter. That represented consists of a slide S, movable across the slot to either open or close the same. The slide is'supported in suitable guideways upon the fixed casing C and is provided at ap'oint beyond the casing with the stud 35, passing through the same, the

. upper portion 36 of the studserving as a convenient finger-piece by which the slide can be moved back and forth as required. The

lower portion of the stud cooperates with astop device, hereinafter more particularly'described, cooperative with the knob K. When the, shutter or slide is drawn back, it is essentialthat the knob should be prevented from movement, and I have illustrated for this purpose a locker controlled by said slide, and the locker may be of anysuitahle type, though for quick action I prefer to employ a spring controlled bolt. The locker represented is denoted by L, and it is movable in a plane transverse to the axis of the shaft 12 This spring-controlled bolt is shown as passing through openings in the inturned flanges 40 and 41 upon the front plate or disk 13, and it is adapted to be thrust into the opening 43 "in the inner end of the cylindrical portion of the knob, as shown by dotted lines in Fig.2.

When the bolt is in engagement with the knob, the latter of course cannot be turned while the slide is open. The opening of the slide shoots .the bolt into the opening 43, and the spring controlling said bolt returns the same to its ineffective position when the slide is fully closed. The retracting-spring for the bolt is denoted by 44, and it is of the coiled type, it hearing at its lower end against the inturned flange 41 and at its upper end being connected to the small pin or projection 45 upon the bolt, the normal tendency of the spring beingito hold the bolt out of the opening 43 and with its upper end in contact with the straight under face 46 of the slide. The slide at a point back of the straightface 46 is provided with a diagonal face 47, extending downward therefrom and merging into the straight face 48 in parallelism with the straightfaee 46. As the slide is drawn out to'the dotted-line position the beveled or oblique cam-face 47 by engaging the upper'end of the bolt L will force the same downward and into the opening 43, and it will be evident that by reason of the pitch-of the face in question a very slight movement of the slide will be necessary to eifect the operation in question. After the oblique or beveled camface has passed off the upper end or head of the bolt the straight face 48 will ride in contact therewith and being in a lower plane than the face 46 will hold said bolt in its Working or set. position while the slide is .out. When the slide is pushed back after the insertion of a coin and when the lower end of the beveled cam-face is opposite the upper end of the bolt, the coiled spring 44, as the slide moves alongafter this point,will force the bolt upward or to its initial position, thereby to effect the release of the knob, so that it maybe freely turned, anda coin of the proper denomination being in the coin or money carrier M the money-carrier will be coupled to the shaft through the wheel 16, so that said shaft can be rotated. The knob K, which is held against longitudinal or endwise movement, is provided in proximity to the plate 13 with the annular flange 50, the distance between the inner face of the flange and the outer face of the plate slightly exceeding the diameter of the lower portionof the stud 35, and said flange cooperates with said stud in preventing the withdrawal of the slide the instant the knob is turned. The peripheral flange 50 has upon what might be. termed its upper side the opening 5l,the width of which is slightly more than the diameter of the lower end of the stud orprojection 35. Thisopening when the coincarrier is in its coin-receiving position is adapted to aline with the lower part of the stud,so that the slide S can be drawn back,and as this operation takes place the said stud will pass through the opening 50. This construction permits the free opening of the slide,and, as previously stated, the instant the slide moves the knob is locked from rotation. \Vhen, however, the slide is returned to its shut position, and after the stud 35 passes through the opening 51, the knob will be released, sothat it can be turned. As soon as the knob turns the stop or flange 50 will be disposed in the path of the stud 35, so that if any attempt is made to draw back the shutter the stud upon an almost-imperceptible movement of the slide will strike the flange, therebypreventing further movement of said slide,

so that the coin cannot possibly be removed afterithasbeenintroduced. When,however, the knob is returned to its initial position after the discharge of a coin, and with the groove 27 in vertical registration with the coin-receiving slot 31, the opening 51 will again be opposite the stud 35, so that the slide can be freely opened.

The construction hereinbefore specified is simple in operation and quick in action, and a double or interlocking mechanism is provided, so that neither the slide nor the knob can be moved until the other one is in its initial position.

The invention is not limited to the precise details previously set forth nor to their arrangement indicated, for these points may be variously modified within the spirit of the accompanying claims, and likewise, as before stated, it can be used in combination with many other styles of machines than those for dispensing gas.
