COlN-ACTUATED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,507, dated April 5, 1892. Application filed November 11,1891. Serial No. 411,626. No model.)

To all whom it may concern.-

Be it known that 1, ROBERT MORAN, a citizen of the United States,residing at Seattle, King county, State of Washington, have invented an Improvement in Coin Actuated Vending-Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of coinactuated machines for vending various articles of merchandise, and particularly for disposing of newspapers, pamphlets, cards, and other similar articles.

My invention consists of the constructions and combinations of devices which I shall hereinafter fully describe and claim.

The object of my invention is to provide a simple, perfectly operating, and accuratelydelivering machine for vending various articles of merchandise, particularly newspapers.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of my machine, the front being broken away to show the interior mechanism. Fig. 2 is a vertical section of the case, showing the interior parts in side elevation. Fig. 3 is a horizontal section through the coin slot. Fig. 4 is a rear view.

A is a suitable case having in its front lower portion a discharge-slot a,which will be more particularly described hereinafter.

In the lower portion of the case are mounted horizontally the feed-screws B B, one on each side. These screws may be made of any suitable material and pitch of thread. For the present purpose they are preferably made of a core or center and a spirally-wound flange, forming a thread of sufficient depth to permit and insure a firm engagement of the papers therewith. In the upper central portion of the case is mounted a screw 13, corresponding in size and pitch to those below.

In the back of the case are three shafts or hubs C, the forward ends of which are connected with the rear ends of the three screws, respectively. Upon these shafts or hubs are the sprocket-wheels D, around which passes an endless chain E, whereby the screws are connected and are revolved in unison.

Upon one of the shaftsC is a winding-drum F, and upon this is wound a cord G, which passes upwardly over suitable pulleys g and suspends a weight WV.

H is a pivoted trip-lever, having a catchshoulder h and cont-rolled by a light spring h. The outer end of this lever lies under the lower end of the coin-chute I, whereby the coin dropping upon it will tilt it momentarily.

Upon shaft 0 is secured a stop J, and in the path of rotation of this stop the-catchshoulder h of the trip-lever H lies.

K is a follower-plate. This has its bottom and top fitted into the threads of the screws B B and lies at a slight backward angle.

L L are fixed rests located beside the feedscrews B.

The operation of the machine is as follows: The papers P are placed with their lower edges supported on rests L L and titted in the threads of the lower screws B. The body of papers rests against the follower-plate K. The parts are all in a state of rest by reason of the engagement of the stop J with the catchshoulder h of trip-lever H. Now when a coin is dropped through chute I it falls on the end of lever H and tilts it. This relieves the engagement of its shoulder with stop J, and the weight WV will then turn all the shafts O and the screws B B will be revolved. The papers will thus be fed forward, the plate K following them up, and the foremost paper will be dropped off the end of screws B into discharge-slot a. Only one paper is thus dropped, for by this time the stop J will have come to fresh engagement with the catchshoulders h of trip-lever H, which has returned to position under the influence of its spring 77.. The parts are then again in a state of rest and ready for a repetition of the operation. The winding-drum F is of advantage in the connection, because as the cord winds on it its diameter is increased, and therefore the weights act more powerfully at first and gradually decrease in power. This is proper, for then the last paper is discharged with no more force than the first. The weight when run down may be wound up again by a crank M applied to the end of the top screw 0. In thus reversing the screws the follower-plate K will be run back to initial posit-ion, ready for the reloading of the machine.

Instead of a weight as the actuating power, I may use a spring-controlled drum or barrel for a power device, and in small or single machines this is to be preferred.

The slot-entrance '1: to the coin-chute is adapted to be automatically closed when the machine is exhausted, as follows: Behind this slot and located in the chute is an oscillatory slotted plug N, having a side-projecting controlling catch-arm n. The plug is normally held by a spring a in such a position that its slot will be out of line with entrance-slot 2', and the latter will therefore be closed.

0 is a pivoted lever controlled by a spring 0. Its upper end is adapted to engage the catcharm n of plug N and to hold said plug in a position with its slot in line with entranceslot 2', and the latter is then open. The lower end of the lever O is in the path of a side arm 7; ofthe follower-plate K. Now when the follower-plate reaches its forward limit and the last paper has been discharged its arm 79 comes in contact with lever O and swings said lever, so that its upper end releases itself from the catch-arm n of plug N, whereupon said plug is turned by its spring a to a closed position and no more coins can be deposited in the machine.

The discharge-slot a of the case is guarded as follows: Behind this slot is a shallow receptacle a',with a depression a in its front wall for permitting the buyer to insert his fingers and reach the bottom edge of the paper after it has been dropped into the receptacle. To the top of the back wall of the receptacle is pivoted a guard plate or shutter a which is held up to a closed position by a weighted arm a but can move downwardly under the weight of a paper. The shutter closes against a flange a having a downwardly-projecting lip a, which protects its edge and prevents the insertion of an instrument with a view to pulling the shutter down.

In order to readily insert and remove the follower-plate K from the threads of the screws 13 and B, I cut a recess or notch 7a in its top edge. In this is fitted a swinging plate k having a pivoted handle it adapted to be engaged between two small studs k Upon inserting the follower the plate k is lowered, and when the follower has reached its proper position with relation to the threads of the upper screw B the plate k is raised to engagement with said threads and held therein by its handle is", fitting between studs 7r.

In order to prevent any of the papers from getting down into the same thread of screws 1) in which the follower-plate K is fitted, I have a spring-plate fitted to the back of the lower portion of the follower-plate and passing forwardly through an opening therein. The lower edge of this spring-plate fits in and fills up the thread in which the follower-plate rests.

In order to provide for the ready removal of the screws and the substitution of others ofdif'ferent pitch for different sizes of articles to be vended I have the following construction: The shafts (J of the several sprocketpnlleys I) in practice constitute their hubs. These hubs on their outer ends are supported upon pointed bearing pins or bolts q, mounted in brackets Q. Theinner ends of these hubs are made conical and hollow and fit freely in sockets in the inner sides of the brackets. The pointed pins pass through into the hollow inner ends of the hubs. The inner ends of the screws are provided with key'pins b, which engage key-slots c in the inner ends'of hubs O, and said inner ends of the screws onter the hollow innerends of the hubs and are supported upon the pointed ends of pins q. The effect of this construction is to connect the screws with the sprocket-pulley hubs, and both are journaled and supported upon the pins (1 and not directly upon the brackets Q. This redueesthe friction and at the same time furnishes a support for the sprocket-pulleys when the screws are removed. The outer ends of the screws are supported and journaled upon conieally-pointed bearings 7', formed on brackets R, having slotted feet 7", which fit over set-screws 0' By tightening these screws the brackets are held in place. 3y loosening them the brackets may be readily withdrawn, thus freeing the outer ends ofthe feed-screws, which may then be removed from their inner end bearings. The tops of brackets Rare downwardly inclined, as shown at r, to facilitate the drop of the foremost paper, and the front ends of the rests L L are likewise inclined for the same purpose.

S is a side guard-rail for the ends of the papers to hold them well in position. It consists of a removable bail providing for the substitution of another of different width for dilterent papers. It is merely dropped into perforated bearingss, from which it can easily be removed.

T is the lower plate upon which the lower screws and connected parts aren1ounted,and T is the upper plate for the upper screw and connections.

In order to prevent the jar of the contact of stop J with catch-shoulder 7L, I make the stop of a springycharacter and back it up by a butter or cushionj, which receives and modifies the shock.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a coin-actuated vending-machine, the combination of upper and lower horizontallydisposed revoluble screws, between which the articles to be vended are supported and by which said articles are held in an upright posit-ion, and a mechanism depending for its operation upon the deposit of a coin in the machine for revolving said screws, whereby the articles are advanced to their discharge, substantially as herein described.
