Application led March 18, 1926, Serial No. 95,743, and in" Great Britain March 23, 1825.

This invention hasreference to improvements in or connected with coin freed delivery mechanism and relates particularly,

to such mechanism vvherein'the packages or articles to be delivered` are alternately arranged and supported in a column, the lowermost package restingon a plurality ofpins projecting from the ends of rods adapted to be rotated through an arc of 90 degrees at a time' for the purpose of releasing a packet Vthe rotation of the said rods being effected through mechanism set in operation by the insertion of a coin. The present invention has for its object the provision of mechanism for eifecting the rotation oi the supporting means 'and for eii'ecting the operation thereof upon the insertion of a coin. n

The invention consists of an improved coin freed delivery mechanism of the kind rerovision of a coiled springfor effecting tie rotation of the said supporting means, the requisite m0- tion eifected by the said coiled spring being r'governed by an escapement mechanism adapted to be controlled through a trip` mechanism actuated by the coin. The invention will Inow be described with particular reference to the accompanying sheet of dravvings,'vvherein:- Figure lis ,a front elevation vof a, coin yfreed mechanism in accordance with the inventionv for delivering packetsof cigarettes. Figure 2 is a side elevation of Fi ure 1. Figure 3 is a vertical section of t eupper portion of the mechanismseen inuFiguresl'. v W

Figure 4 is a plan of Figure 1, andf y"Figure 5jis a sectional plan on the line 5-5 of Figure 1. i -The-packets 6 are arranged alternately in v a column and supported by means of pins 7 which project equally oneither side of the lower ends oiffeed rods 8. These rods 8 are 'rotatably mounted at their upper and lower ends Within bearings formed in

plates

9 and 10 respectivelyl said plates 9 4and 10 being maintained apart by means of a distance` piece 11 secured to eachof the said plates 9.and 10. In addition, the plate 9 is vadapted to embrace a pairl of oppositely dise Vplate 14 which constitutes the bottom housing plate for the actuating mechanism.

`a common spur Wheel 17' secured to a casing 18 adapted to contain a clock spring 19. One" end of the clock spring 19 is anchored to ashaft 20 rotatably mounted in the bottom plate 14 andin a plate 21 forming the top plate ofthe housing for the actuating mechanism, thespring 19 being adapted to be tensioned by means-of rotation of the vshaft 20 by a knob 22 secured thereon.

,'Secured to the lower section of the main shaft 20 and rotatable therewith is a cylin- Vsaid numerical markings being observable through a Window disposed at the front of ythe casingor housingvvithin which the apparatusis normally located and serving to denote the number of packets remaining in the machine. Secured totheupper surface of thenplates 9y are four cqui-'distantly 'spacedleaf springs 24 the free ends whereof are adapted to co-operate with a plurality of correspondinglyspaced'angle brackets 25 se curedk to "the undersurface of the bottom housing plate 14 said springs 24 andangle brackets--2`5 cooperating tolsecure the container unit to the actuating mechanism.

Thepinions 16 are also provided with upwardly projecting bosses 16a the upper ends whereofy are rotatably mounted in bearings formed-fin :the top housing plate 21. Secured'to one of these bosses 16'n1 is an escapement Wheel 26 carrying four stops 26L Which Vare' arranged at 90 degrees apart the escapementwh'eel 26 being disposed above the top housing plate21.

\ Adapted-to 4engage With this escapement wheel is a yforked es'capement lever 27 the arms 27a whereof engage with the stops 26l onV the escapement wheel 26 said lever 27 being pivotally mounted on a spindle 28 projecting from the top 'housing plate 21. The lever 27 is pivotally connected at itsother end to a link 29 said link having" at the end "drical 'drum' 23 provided with numerical markings around the periphery" thereof thereof a pin 29b adapted to engage within a notch 30a formed in a quadrant 30 secured at the upper end of a rod 3l which is rotatably mounted in a sleeve 3l" secured to the iousing platesv lat and 2l. The lower end mounted on a pin 33 secured to a bracket carrie-d by a 'Hired rod 34. The other arm ot' this trip lever 32 is provided with a cranked Section 32" which is adapted. to project withinthe coin chute 35 and to be depressed by the coin during its tall a spring 36 anchored at one end to the trip lever 32 and at the otherend to a pin 37 project-ing Yfrom the bracket 38 being provided for returning the trip lever 32 to its nornial position.

The escapement lever 27V is connected to the piston rod 38 ot a double acting dashpot 39 tor regularizing the action of the mechanism.

Secured at the lower end of a rod ll() is a shutter il adapted to close the coin slot 35a when the word empty appears on the drum 23 suitable gearing .being provided to ensure synchrony between the drum 28 and the shutter al.

The escapenient lever 27 is also provided with a pin 27C adapted to have connection with a cranked arm vll2 adapted to actuate a counting mechanism 43 said counting mechanism beingsecured to the bot-tom housing plate by means ot a bracket 44- the indications oi the counting ymechanism :being visible through a window formed in the case or housing within which the mechanism is located.

The operation of the mechanism is :as vfollows: Upon the insertion of a coin in the slot the said coin traverses the chute 35 and in its passage strikes the cranked arm 32h oit the trip lever32 which projects within the said chute. This lever 32 is depressed by vthe weight ot the coin and thereupon raises the other arm whereby the arm 3la of the rod 3l is `treed tromengagement with the stop 82 on the :upper jaw ot .the trip lever 32 and allows the said-arm 3la tomove in an anti-clockwise direction. The rotation ot the .arm 3l however is temporarily arrested by a stop 32C on thelower jawot the trip lever '32, `the initial .motion however thus permitted admits of the partial disengagement ot the pin 29b on the link 29 in connect-ion with the escapeinent lever 27 from within its notch 30a in the quadrant 30. Upon the release ot the coin from kthe chute the trip lever 32 rises and permits of the disengagement ot the arm 3la from the stop 3J on the lower jaw of the-trip lever 32 and admits ot the arm 3l continuing its anticlockwise motion. This continued motion admits ot' the complete disengagement of 4ends .thereof whereby the lowerinost packet G is treed and allowed to tall into the 'delivery chute. Simultaneous with the lpartial release ot the escapement wheel 2G two of .the stops 26 on the said wheel icome into engagement with the forked arms 27El of the .escapement lever 27 .and return the :same to its initial position. rllhe gquadrant :30 and link 29 are also returned totheir initial position `by means et springs vand 46 crespectively .connected therewith, Ia stop if? being` provided to limit the return motion ot' the quadrant 30. The motion of theescapeinent lever 2? is retarded by means vof the dashpot 39 whereby a sufficient period-of time elapses between the successive operations of the trip mechanism to `admit .of the rde-livery of ythe t.

packet without causing any jamming of the several parts of the mechanism.

A coin treed delivery mechanism constructed as hereinbefore .described admits of the whole of the mechanism .being enclosed :ing a dispensing mea-ns, ayspur wheelradapted to be driven from said shaft, an escapement wheel adapted to be driven yfrom said spurv wheel, stops .arranged kat .90 :degrees apart on said escapement wheel, an escapement Jever adapted Ito cio-.operate '.Withsaid escapement wheel for Aeti'ecting the release ot the said lever subsequent :to 'the insertion ot a coin .and ,trip `mechanism Iadapted for actuation :by the coin for controlling the operation of said lever.
