To all whom t may concern.-

Beit known that I,ANrHo1\;Y HARRIS, a subject of the Queen of Great Britain, residing at Middlesborough, in the county of York, in the Kingdom of England, have invented certain new and useful Improvements in Coin Freed or Actuated Machines, (for which pro-I visional protection has been obtained in Greaty Britain, No. 8,098, dated Junet, 1888,) of which the following is a specification.

Thisinvention relates, broadly, to that class of machines 0r appliances in Which'the Whole or a portion of the mechanism is freed or actuated by the insertion of a coin into an opening provided therefor.

More particularly the invention relates to the construction and arrangement of certain mechanismsin connection with the coin oriiice or chute, With the object of preventing the insertion into the machine of, first, disks, coins, rings, or other similar articles of lead, card-board, or other soft material, hereinafter called leaden disks, and, second, disks, rings, Sac., of iron, steel, or other magnetic material, hereinafter styled iron disks.

The invention may be understood by reference to the accompanying drawings, in Which- Figure 1 is asection through the coin orifice and chute, showing an arrangement for preventing the insertion of leaden disks. Fig. 2. is a similar view illustrating a Way in which the arrangement shown in Fig. 1 may be fraudulently circumvented.

chute being shown in section. Fig. 19 is a sectional plan on the line l6 G, Fig. 18, of the under side of the mechanism shown in said figure.

B is the coin-orifice of a machine such as described.

Leaden disks are prevented from being introduced into the machine by the following device: A pair of movable blades, strips, or

arms (hereinafter"called gripping-arms are mounted Within the inclosing-cabinet of the machine in proximity to the coin-orifice B', and are each provided at or near one end with a knife-edge or a series of points, such edges or points being hereinafter callec gripping-edges. The said arms are mounted with their gri pping-edges opposite each other, one on each side of the path of the coin, in such a manner that a hard coinor disk inserted at the coin-orifice B will bear Wit-h its periphery against the gripping-edges and will under slight pressure thrust apart the gripping-arms, so that the said coin or disk' may pass fart-her through the coinforice, whereas a leaden disk, when inserted into the orifice and pressed against the gripping-edges, will have its periphery indented by the latter, so that the arms will not move apart and the further progress of the said disk will be prevented. In combination with the grippingarms I also employ a suitable stop device,

` same or a similar stop device.

which. is so arranged that should the resistance of the gripping-arms be insufficient to prevent the entry of a leaden disk thrust forcibly into the coin-orifice the increased pressure required to overcome such resistance shall be the means of so changing the position of said stop device relative to the path pursued by the disk that the forward edge of the disk shall come in contact with the said stop device, which effectually prevents the disk from being thrust farther through the coin-orifice. To prevent iron disks from beingintroduced into the machine, I employ the In this case, however, an abnormal pressure on the gripping-edges being an unavailable source of power, on account of the hardness of the iron disk, I employ one or more permanentor electro magnets, which are so located and arranged in proximity to the coin-orifice that the mutual attraction between them and an iron disk inserted into the orice becomes the means of changing the position of the stop device relative to the path pursued by the disk, and thus, as before, preventing the farther progress of the disk through the orilice.

The gripping-arms may be formed of flexible strips C, Figs. 1, 2, and 3, which are attached to opposite sides of the coin-chute B or other convenient part, and are provided upon their converging extremities with gripping-edges A, located as above described; or the gripping-arms may be mounted in a flexible manner one on each side of the coin-chute,

, as at C', Figs. 5, 6, 18, and 19, their grippingedges A being located upon the edges of the arms at or near their outer ends, as shown; or they may take the form of pivoted arms C2 with gripping-edgesA upon their edges at or near their ends, as in Figs. 7, 8, and 9, or of pivoted arms C5 with their gri pping-edges A at their extreme ends, as in Figs. 10, 11, 12, 14, 15, 1 6, and 17, or of sliding arms C3, as in Fig. 15, having 'their gripping-edges located upon their extreme ends. In cases where the arms are not in 'themselves flexible, I provide' them with returning-springs or their equivalent, as hereinafter set forth, whereby they are returned to their normal positions after havin g been thrust apart by the passage of a coin. In each case, however, the gripping-edges are located, as above described, with respect to the coin-orilice and coin-path so that a coin can readily thrust the grippingarms apart and pass into the coin-chute, whereas a leaden disk is arrested by them at v.the entrance tothe chute and prevented at the same time pressed inward, it will be found that the gripping-arms C are thrust apart, and in this way a leaden disk may be inserted into the machine in spite ofthe gripping-edges A; The above class of fraudmay be prevented by the arrangement shown in Figs. 3 and 4. The coin-orifice is provided, preferably, beyond the outer wall B2 of the machine, with a mouth-piece B3, which is cut away at the sides, as at b, to enable the fingers of the operator to push thecoin to a sufcient distance into the coin-chute B. The mouth-piece is provided with two tumblers E, pivoted at or about their centers, as at e. The opposing edges c of the tumblers are curved, as shown, the curve being an arc of a circle having' a radius equal to or slightly larger than that of the predetermined coin by which the machine is to be operated. The upper ends of the tumblers may, if desired, be held normally apart, as shown in dotted lines in Fig. 3, by springs e2, so that a coin can always be inserted between them. These springs may, however, in some instances be dispensed with, the tumblers being simply held `normally in their parallel position, as in Fig. 3. In this case when the edge of a coin D or iron disk is inserted into the mouthpieceit forces the upper ends of the tumblers apart, passes down between them, and thrusts apart their lower ends, being afterward pressed between the liexible gripping-arms C, as in Fig. 1. Aleaden disk might possibly be got in between the tumblers; but it could not be forced past their lower ends and into the coin-chute B by reason of the arms C. If a wire or similar article were fraudulently inserted into the coin-orifice, as described with reference to Fig. 2, it would be impossible to get a leaden disk of the proper size past the tumblers, as the space between the latter is only just large enough to admit the said disk.

/Vhen the gripping-arms are employed in combination with a stop device, as hereinafter set forth, such stop device is located in proximity to the coin-path behind the coinorifice and preferably at such adistance from said orifice that it is impossible to force more than about a half or three-quarters of the leaden disk into the coin-chute.

The above combined stop and gripping device may be arranged in a variety of ways, of which the following will serve as examles. p In the arrangement shown in Figs. 5 and 6 the flexible gripping-arms C are carried by a frame F, which is pivoted at f, and is provided with an arm f adapted to engage a sliding spring-stop G Gf. Vhen a leaden disk is inserted at B and pressed against the grippingedges A, the latter grip the edge of the disk andthe arms will not open. If sufficient pressure be applied,the frame F is turned upon its pivots so that the spring-stop G G is engaged by the arm f and is thrust forward across the money-chute B. On withdrawing the disk the frame and stop are returned to TOO IIO

. the frame F.

- their normal position by the spring G. This' spring and the equivalent springs described hereinafter in reference to modified forms of the mechanism are of sufficient strength to prevent the frame from moving under th'e slight pressure due to the insertion of a coin or iron disk into the coin-orifice.

In Figs. 7, 7n, 8, and 9 the gripping-arms C2 are mounted upon pivots c2, which are carried by a rocking frame F pivoted at f and provided with coiled returning-springs G3, each located between the free ends of the arms constituting a portion of the rocking frame F and the under side of the casing of the machine. The springs are compressed when the frame F is rocked on the pivots f to project the stop G4, and react and restore the frame to its normal position. The stop GL is mounted upon a iiexible or counterbal? anced arm G2, and is adapted to be engaged by one arm of an angle-lever f2, the other arm of which is connected by a link f3 to one end of the frame F. Then aleaden disk is inserted into the mouth-piece B3 and pressed against the gripping-edges A, the arms C2 will not open,but are pushed against The latter turns upon its pivots f and carries with it the link f3, thus causing the lever f2 to be moved so as to insert the stop G4 into the money-chute B. On withdrawing the disk the frame is returned to its original position by its springs G3 or by abalance-weight G5, attached to the magnetvJ, and the stop is withdrawn from the chute.v A warning-bell II may also be provided. The hammer hof the bell is mounted upon a flexible arm, or in other suitable manner, in proximity to the bell. A tappet h on the rocking frame F is arranged to press the said arm outward, and to suddenly release it each time the frame is depressed. The' tappet is preferably spring-jointed, as shown, so that it may return to its normal position on the return of the frame. Instead of the above arrangement of bell, the tappet h may be the means ot' causing an electric or other bell to sound either within the machine or otherwise.

- In the arrangement shown in Figs. 18 and 19 the iiexible arms C', bearing the grippingedges A, form part of the sides of a rocking frame F2, which is pivoted at f, and is provided at one end with a returning-spring Gi or its equivalent. The other end of the frame gibs-connected by a cross-piece f and anglelever f2 with a slidiu g stop G, -which is adapted to be inserted into the coin-chute B. The connection between the cross-piece f4 and the angle-lever f2 is of such a nature that the arms C can move freely apart, as above described, when a coin or iron disk is inserted at the oriiice B and pressed against the gripping-edges A. To this end the cross-piece f4 may be made in two lengths, the outer ends of which are attached to the arms C', while their inner or adjacent ends are provided with lugs f5, through which a pin f6, fixed on the angle-lever f2, passes loosely. The action of this mechanism is precisely the same as that of the mechanism described in reference to Figs. 7 to 9.

Vhen a magnet or magnets is or are employed in combination with a stop device, as hereinbe'fore set fortlnfor the purpose of preventing the introduction of iron disks into the machine, the said magnet or magnets is or are arranged with its or their poles behind the coin-orifice in proximity to the coin-path and so connected with or arranged with respect to said stop device that the mutual attraction between the poles and an iron disk inserted into the orifice becomes the means of changing the position of the stop device relative to the path pursued by such disk in such a manner that the forward edge of the latter comes in contact with the stop device and its further progress through the coin-orilice is prevented. The magnet or magnets'maybe either fixed or movable, and when more than one is employed a part of them may be fixed and the remainder movable. Vhen a 'movable magnet is employed, it may be hinged, pivoted, or otherwise mounted in such a manner that it will be easily moved either by its attraction for an iron disk fraudulently intro-- disks into the machine, although either arrangement might be used separately. Vhen either one or both of the movable grippingarms may serve as an armature or armatures for one or more of the magnets, the contact of the Said armature or armatures with the poles of the magnet being thus broken each time an iron disk or a coin is inserted into the coin-orifice. It will be obvious that the said magnets and stops and their connections can be arranged in a variety of ways. The following examples will, however, sutlice to explain the scope of theinvention. A

In Figs. 5 and v6 the magnet J, which may, it' desirable, be composed vof two or more IIO magnets laid side by side, is pivotally mounted The poles of the magnet are preferably and its forwardmovement assisted by a spring K. The armatures L of the magnet are formed upon or attached to the ends of the grippingarms C in such a manner that they are removed from the'l magnet -each time the said arms are thrust apart by a coin or iron disk inserted into the coin-orifice. A projection 32, carried or actuated by the magnet, is arranged to engage the arm f of the grippingarm frame F each time the magnet moves towardl the coin-chute.

The mode of action ofthe above mechanism is as follows: Vhen a coin or au iron disk is inserted. into the coin-orifice B', it forces the gripping-arms C apart and removes the armatures L from the magnet without operating the frame F by reasonof the resistance of the spring G, as before set forth. A coin is then free to fall down the coin-chute B Without operating the magnet. An iron disk, however, will, as soon as the armatures are removed from the magnet, be attracted to the side of the coin-chute nearest the magnet, and the latterwill move forward bodily toward the said disk, carrying with it or actuating the projection 72. The latter engages the frame-arm f and causes the stop G to be thrust across the coin-chute, so as to prevent the further passage of the disk. As soon as -the coin has passed'ndown the chute or the iron disk is withdrawn therefrom the armatures are again attracted to the magnet, and

` -the spring G returns the frame F and the magnet to their normal positions.

.will operate the stop G, as before described in reference to the figures under consideration.

In the arrangement shown in Figs. 7, 7, 8, and 9 the magnet J is mounted upon trunnions ja, so that its poles are capable of moving in a line approximately parallel to 'the coin-chute B, which is preferably open just opposite the said poles. The rear end of the magnet is connected by a link K with a double rocking arm K2 in such a manner that each oscillation of the magnet causes a double stop k, carried by the said arm, to be inserted into or withdrawn from the coin-chute. Then the magnet is at rest, its poles are held in an elevated position, as shown, and the stop 7c is withdrawn from the chute by the spring G7 aforesaid orits equivalent, such as the weight G5, attached to the magnet. The armatures L are, as in Figs. 5 and 6, carried by the extremities of the gripping-arms C2. Springs or stops C prevent the armatures being forced apart beyond the magnetic infiuence. The action of a coin in this apparatus is identical with that described with reference to Figs. 5 and G. An iron disk, however, instead of drawing forward the magnet bodily when the armatures are thrust apart, is attracted to- ^ward and adheres to the poles of the magnet. Any further inward pressure upon the iron disk causes the magnet to turn upon its trunnionsj,and(throughthemedium of thelinkK lbefore described.

l and arm K2) to thrust the double stop 7.: in front the disk by the spring G7 and the attraction of the magnet. The action of a leaden disk on the apparatus has already been set forth. It will be seen, however, from Fig. 9 that the gripping-arms C2 are held normally at a short distance from the frame F by a light spring c2. When, therefore, a leaden disk is pressed against the gripping-edges A, the arms C2 will slideon their pivots for some distance before depressing the frame F. During this first movement of the arms the magnet J is also depressed by reason of its contact with the armatures L, carried by the said arms, and it moves the double stop 7c across the coin-chute. On the depression of the frame F the stop G4 is inserted between the double stop 7s, and the leaden disk has thus three stops opposed to it.

In Figs. l0 to 13 an arrangement is shown in which two magnets J 2 J 3 are employed, one on each side of the coin-orifice. The magnets are preferably so placed that their edges adjacent to the coin-orifice are nearer together than their edges remote from the said orifice. One magnet J2 is hinged, as at jt, by its upper edge to the wall B2 of the machine, and the other J 2 is located in a similar position, but is a fixture. The magnets are held normally apart by a light spring j or its equivalent, or they may be so mounted as to fall apart by their own weight. armature L f or both magnets is identical with one of Vthe pivoted gripping-arms C5, hereinbefore mentioned, and is hinged to the magnets at l, its gripping-edge A being located behind one end of the coin-orifice, as

The other pivoted gripping-arm C5- has its gripping-edge A located behind the opposite end of the coin-orifice, as shown, and the arm is held inlits normal position bya spring C4, orby a weight C7; or the latter arm may be a ieXible one, as in Fig. l. One or more stops G2G8 are provided on each magnet. The mode of action is as follows: Then a coin D is inserted into the coin-orifice B between the magnets and pressed 'against the gripping-edges A, it thrusts aside the pivoted gripping-arm C5 and the armature-arm C5 L into the position shownin Fig. 12, the outward movement of the armature being controlled by a stop Z. freely down into the machine between the stops G8 G8, as may be understood by reference to Figs. 1l and l2, in the former of which the armature-arm is not shown. D2 be inserted into the coin-ori [ice and pressed against the gripping-edges, the arln C5 and armature-arm O5 L will be thrust apart, as in Fig. 12; but the disk will be attracted to one or other of the magnets, as shown in Fig. 13, so that when pushed farther in it will catch upon one of the stops G8. If the disk is adhering to thehinged magnet J2 and an at- The d IOO IIO

The coin then drops 4 If an iron disk I tempt be made to shake it over toward the fixed mag'net J 3, the magnet J 2 will be drawn over in spite of the spring j, and the stops Gs will be brought together, themagnets being retained in this position by their mutual attraction for the iron disk. This may be understood from Fig. 13, in which the armature-arm is not shown. When the magnets are in the position shown, the iron disk D? cannot be forced past the stops G8. As soon as the disk is withdrawn the magnet J2 is moved backward by the spring j, the armature-arm C5 L falls against the poles, and the gripping-arm C5 is returned to its normal position by the spring O4. Should an attempt be made to insert a leaden disk D', Fig. 10,

into the machine, the edges A will grip the disk, as before. By dint of great pressure the armature-arm C? L might be forced off the magnets, as seen in dotted lines but the opposite gripping-arm C5 would take up another position within the coin-path, also shown in dotted lines, and would effectually debar any further progress ot the disk.

In Fig. 14 two fixed magnets J 3 J 3 are shown, each provided with a stop GrS on each side of a groove C, down which the good coins are able to pass. The power of the magnets is, however, too great to permit of an iron disk being passed centrally down the groove between the stops, and the disk is consequently attracted to one or other of the magnets, so that itcomes in contact with one of the stops G8 and is prevented from being inserted farther into the machine.

The mechanism shown in Fig. l5 is arranged in a similar manner to that described in reference to Figs. 10 to 13. One of the grippingarms is, however, in the form of a sliding arm C3, provided with a returningspring C8, the other gripping-arm being apivoted armature-arm C5 L, similar to thatshown in Fig. 10. The magnet J2 is hinged atj4 in such a manner as to fall away from the fixed magnet by its own weight, and it is provided with two stops GS, which interlock with a stop or stops on the fixed magnet. The mode of action is the same as described with reference to Figs. 10 to 13.

In Figs. 16 and 17 two small magnets J4are shown hung by their polar ends upon the pivots j ateach side of the coin-orifice. The lower ends of the magnets are held normally apart by two light springs g', or their equivalent. The stops GS, which preferably interlock, are carried by the small magnets J 4. B4 is the coin-chute. The coin is guided centrally, so as to fall clear of the stops G8, by a mouth-piece B. An iron disk inserted into the mouth-piece causes the magnets J 4 to be attracted to it, so that they approach each other and place the stops GS across the path of the disk. The small magnets may be accelerated in their closing movements, and may be held more firmly closed by the-aid of two larger fixed magnets J 5, which are placed outside the smaller magnets and in a similar position thereto, and have their poles so arranged with respect to the polesof the smaller magnets that as soon as the armature-arm C5 L is removed a repelling action takes place between the smaller and larger magnet-s, p

whereby the former are quickly brought together and held in their closed position. The

power of the larger magnets is not, however, suflicient to repelthe smaller ones unless the movement of the latter is also assisted by' their attraction for an iron disk inserted between them. The armature-arms C5 L are thrust apart, as before, by the pressure of a coin or iron disk upon the gripping-edges A.

IThe armatures are pivoted a considerable distance outside their centers of gravity, as at Z2, so that their weight assists the pull of the magnets; or the large magnets J5 may be placed horizontally, as in Figs. 10 to 13. In this case only one gripping armature-arm C5 L is employed, the other gripping-arm being simply a flexible sliding or pivoted arm, as before described; or the larger magnetsmay be dispensed with and the gripping amaturearms arranged to act in conjunction with the magnets J4.

Instead of permanent magnets, such as shown in the drawings, I may employ an electro-magnet, (or magnets,) which I may so arrange that an iron disk, on'being inserted into the coin-orifice, willremovean armature from the ends of the already polarized core, or will complete the circuit round the core, either directly through itself or indirectly by actuating a suitable contact or contacts connected with the circuit-wire.

I claim as my invention- 1.
