ToIaZZ whom t mag/concern.'

Be it known that I, WILLIS A. WEAvER, a citizen of the United States, and resident of Detroit, in .the -county of Wayne and ,State of Michigan, have invented a new and useful Improvement in Sandwich-Vending Machines, of which the following is a speciy interior package receptacle; and also a fication. l

This invention relates to sandwich vending devices adapted to be installed in public and other convenient places for'dispensingv sandwich lunch packages and other desirable articles for which the device may be adapted and employed.

The object of my invention is to provide a simple and practically useful device that is conveniently accessible at all times for the purpose of supplying persons desiring sanitary, economic, quick and light ready lunch service. Y

A further object is to provide a coin controlled device whereby a coin of the required denomination must first be dropped in the machine in order to complete the successful operation of the mechanism thereof; and 'also,fa package discharged into the pocket receptacle of the delivery door of the cabinet, which' automatically unlocks same for. its removal. This .-mode of construction renders the machine closed, auto- 'rnatically locked and unlocked, and 'more completely sanitary by obviating any susceptibility of the interior of the cabinet or any of the packages contained therein to the collection of, or contact with dust, 'or contamination with other particles of unsanitary matter.

The e objects andpurposes I attain by the evice illustrated in the accompanying drawings, in which Figure 1 represents a front view of the exterior of the cabinet' Figure 2 islan enlargedsectional view of Fig. 1, on line 2 2,'looking to the left, showing in part the incased mechanism employed to operate the device; Figure 3' is a transverse cross sectional view on line 3 3, Fig.l 2,

' looking down, showing the front and rear metal angle lates which form the rectangular hollow s ape oflthe package receptacle, with the lower ends of their front panels bent and inclined forward, and alsoa side.

sectional view of the swinging-plate 6, which controls the opening and closing of the outlet for packages passing through the re-V ceptacle channel at this point; Figure 41s Ia detail view of Fig. 2, in' section on lineV -4 4,*looking to the right, showing a cross glass D in the front panel of the delivery door 5, rendering the visibility of packages when deposited into the' pocket receptacle on the interior side thereof; Figure 6 i-s a sectional view-of Fig. 5, on line 6 6, showing in'perspective the interior compartment of the package delivery door 5, and also the swinging or oscillating latch attachment 24,

employed for automatically .-'locking said door; Figure 7 is a broken transverse view of the front panel ofcabinet 1, on line 7 7, 6, .showmg a plan view of the interior si e of the package delivery door 5, and also the automatic oscillatin swing locking attachment 24,` with their upper arm extensions 24', pivotally attached at 24A, to the interior lside of the front panel of cabinet 1, one on each side of, and directly .above the door casingyof said door 5, and

provided with guide plates 25, attached tol the interior side of the front panel of the cabinet, for holdingthe latch plates 24 in li-ne when they swing' outward or inward,

and with the lower integral free arm exl tensions 24 curved so as to slightly extend, one on each side of, and into the pocket receptacle of the delivery door 5; Figure 8l is a detail view in pers ective of the pack- Vage delivery door 6, s owing the interior' pocket constructionvvthereon formed by the side flanges 5,and with the bottom flange bent upward forming 'the rear panel 5;

also the slots 27 -in the upper portion of the 'side flanges 5'; and Figure 9 illustrates the rearl package supply door 21 in a side view, inclined and partly open with dotted positions of packages as they appear arranged in the holder or receptacle 3, attached to the interior side thereof.

Referring to the drawings, 'similari nu-n m'erals and letters of reference refer to similar parts throughout the several views. The cabinet 1, provided with a delivery door 5, for the removal of purchased pack- I ages, hinged or ivoted, preferably at the bottom of the ooi` casing in the front panel of the cabinet so as to swing and open outward; a slot.10 for the movement of an operating lever l; a depositing coin slot 17' registering with the perpendicular receptive end 17B, of the coin channel member 17 of the interior mechanism of work of the device, and shown in Figs. 1, 2,

slightly 5 and 9.

The interior mechanism and construction of the device inclosed in cabinet 1, consists of a package receptacle formed by the two semi-rectangular shape metal plates 2 and 3; the former being attached to the interior up er side ot the front panel of the cabinet. 1', y means of brackets 2", while the latter is similarly attached by brackets 3' to the opposite interior side of theesupply door panel 21, with the lower front panel ends of both similarly flared or bent forward in parallel inclines 2' and 3', respectively, and which extend upward from the bottom, also from the turn-plate 6, a little more than the thickness of a package contained in the o.

receptacle, as indicated in Fig. 2.

` It will be seen that the arrangement of the two semi-rectangular shaped metal plates 2, 3, in this manner, with their channel chambers facing and contiguous to each other, :torm a repository and receptacle for the packages or articles vended by the machine. And for controlling and discharging articles from the outlet at the bo-ttom or lower end of this package receptacle, a turn-plate 6, is pivotally attached to the side iian es ot the rear channel plate 3, ack oity the incline projection 3', thereof, and which is provided with rear arm extensions E, terminating in a for ward upper curve engaging the slot-openings 6', provided :tor same in the incline projecting flange 3' ot the rear channel plate 3. These arm extensions E, are adapted to move forward through the slot openings 6' under the package directly above the one supported on pivotal plate 6, when said plate is turned downward to the inclined dotted position indicated in Fig. 1, and which causes a package thereon to slide oli' throughv the channel of a metal guide 4,

.into the receptacle of the delivery door 5, thus permitting the swing-plate 6 to be returned to its horizontal closed position by means of a spiral coiled spring 7, attached to one of the arm extensions E and the interior side of the rear panel of the cabinet, as shown in Fig 2. j

The coin channel member 17, with which the machine is provided, is attached, pref erably, to one of the interior side panels of The horse-shoe magnet 16, controlling al slot opening 16- provided in the rear end ot the coin channel member v17, and employed for the removal of slugs that may be dropped in the machine, is integrally attached to the leverfarm 15, which is pivotally attached to the interior side of the cabinet at 15', the short arm of which is -pi'votally connected to the operating lever 10, by means of a short connecting rod 14.

lLever 9, pivotally attached at one end to the `interior side of the front panel of the cabinet at 9', the movement of which is controlled by a connecting-rod 8, pivotally attached to it and to the drop-plate 6, 'is employed and arranged so that the free end thereof will control the slot opening 9" at the lower bottom end of the coin channel member directly under the plunger 12, and which is provided for the outlet of coins deposited in the machine for the purchase of a package, and through which. coins are Jforced-under the ressure of and contact with the sliding p unger 12, in its downward movement, as indicated by dotted positions in Fig 2.

To render the sanitary condition of the cabinet more complete, the delivery door 5, is provided and placed in the front panel of the cabinet with the fia-nge extensions as indicated in Fig. 8, which over-lap and con,- tact closely the front panel .casing of theexterior cabinet, as shown in Figs. 1 and 5, and in section in Figs. 2, and 6. This arrange ment obviates the tendency of dust or other particles of contaminating matter collecting in the interior pocket receptacle of the delivery door 5, or the interior of the machine from the outside.

The delivery door 5, is also shown in Figs. 6 and 7 provided with two swing-latches 24, having their `upper arm extensions 24' pivotally attached to the interior side of the front panel of the cabinet 1, one each side of, and over the door casing at 24A, and with their free arm-extensions 24" curved so as to extend insidey of the door pocket andflanges 5', Which-form the sides thereof, and in contacting position with packages discharged from the drop-plate 6, through the guide channel 4, into the pocket receptacle of said door 5, and which in'their movement contact with and force the said swinging latch plates 24 to swing outward a suiiicient distance to disengage them from the slot openings 27 in the side-flanges 5' of the delivery 'door 5, tlius permitting the same to be opened and the packageremoved from the pocket thereof, and when the door is released, by freeing the hold of the knobfor handle thereon, it automatically closes by means of the spiral coiled spring 5v at- Y terminating in a'fiared incline rearward, so

that the swinging endofthemdrop `plate 6, will contact therewith at .its extreme open position, similarly as indicated in dotted` position in Fig. 2.

The metal guide plates 25,-with' recessed flange extension bent at right-angle to the base thereof, and in which the latch-plates 24 are free to move, `are attached to theinterior side of the front panel of the cabinet, are employed for the purp-ose of obviating any lateral motion ,of said plates and to retain them in proper and positive positions of alignment with the slots 27 when the delivery door 5 is closed; and the beveled edge 26 of the latches 24 enable said latches to move outward more easily when contacting with the flange sides 5 on` the return of said door to its normal closed position, illus-y trated in Figs. 1,5 2, 5, 6 and 7.

In Figure 1 is shown a view of the exterior of the cabinet 1, in which the packages vvended are invisible, while in Fig. 5 shows the cabinet provided with a glass C in the front panel thereof which renders some of the packages contained in the supply'` receptacle or holder, Visible, and also a glass D in the panel of the deliverydoor 5, to render a package visible when `dropped into the pocket receptacle thereof. ,Either of these methods may be employed without affecting the operation of the device/or the spirit of my invention.

In the operation of Jmy device, the supply receptacle is first' filled with packages of uniform size, and preferably, one upon and Y lnation is inserted in slot 17 above the other, similarly as illustratedy in Fig. 5, and also in dotted position in] Figs. 2 and 9. The lower bottom package in the perpendicular supply channel, by virtue of its own weight, and whichv is augmented bythe weight of the packages above it, will move down and forward into the incline channel chamber at the base of said supply `receptacle and rest on the drop-plate 6, and

in which osition it becomes partly relieved of the weight of the packages above, which becomes checked by the next lowerpacka e `resting on theincline projection 3', simila y as indicated in Fig. 2.

And when a coin of the required denomiit will drop into the rece tive end 17 B, of the coin channel member 1 and rolll to the rear .end thereof, directly under the sliding plunger 12,

and into the slot 9" and rest on the free end of the lever 9, controlling-the opening and closing of said slot; and With a part of its .periphery contacting with the magnet 16 in the slot opening 16', as indicated in .dotted position in Fig. 2; then by pressing closing movement of the lever 9, will like- Wise cause a similar andl simultaneous movey ment of the swing-plate 6, as both are piv-l otally connected by rod 8, shown in Fig. 2; and lalso by the downward and open movement of drop platev 6, a package thereon Will be discharged through the guide channel 4, into the pocket recept-acle of the delivery door 5, and lin this movement of .package transference, the said package contacts with the free ends 24 of the swing latch plates 24, moving them back and' from disengagement in the slots 27, thus, unlocking and permitting the delivery door 5 to be opened and the package removed from I the pocket thereof.

The magnet 16 is employed to reduce the loss of packages in case where metal slugs are dropped into the machine for the purposeof defrauding same; and especlally when said slugs are made of such metals as may be affected and attracted by a vmagnet. In myv device the polar ends' of a horse-shoe magnet 16, close and control the opening, slot 16. for the removal of `slugs in the coin channel member 17, and which swings outward and upward" to the dotted position indicated in Fig. 2 wheny the oper- 1 ating lever 10 is pressed down, and by means of the .ivotal lever 15 integral therewith being` pivotally'connected tothe said operating lever 10 by the short lever 14, the said magnet 16 will simultaneously move outward drawing any metal slug affected thereby through the slot opening 16', whence it then drops to the bottom of the cabinet 1, without operating the delivery and drop plate 6, or causing a package to be ydischarged or delivered.

I-Iavin thus described my invention, what I c aim is v 1. In a coin controlled mechanism, a coin channel member having bottom and` end outlets, and also provided with a plunger guide above the bottom outlet; a plunger -mounted in said -plunger guide, an operating lever connected to said'plunger, a second lever operatively connected to the said vfirst lever, a magnet carried by the said second lever and normally located at the end opening, and a member below said bottom opening adapted to operate a vending machine. 2. In a coin controlled mechanism, a coin channel member having bottom and end outlets, and also provided With a plunger guide above the bottom outlet; a plunger mounted in said guide, an operating lever connected to said plunger, v'a second lever lever operatively connected to the first lever, a magnet carried by the second lever and normally located at the end opening.

3. ln a device of the character described, the combination comprising a coih channel member having botto-m and end outlets, and also provided with a plunger guide above the bottom outlet, a plunger mounted in said plunger guide, an operating lever connected to said plunger, a spring connected to said character described, consisting of a co-inchannel member having, bottom and end outlets, and also provided `vvith a plunger guide above the bottom opening; a plunger mountedin said plunger guide, `an o-perating lever connected to said plunger, av spring connected to said lever for retaining it in normal position, a second leveroperatively connected to the iirst lever, and a magnet carried by "said second lever and normally .located at the end outlet, and a member below said bottom opening adapted to operate a vending machine. v
