CONVEYEB SYSTEM.

Applicationjled May 17, 1921. Serial No. 470,441.

To all whom concern: 9

Beit known that I, HENRY W Sroorma, a citizen of the United States, residing'm the borough of Brooklyn, county of Kings, and

State of New York, have invented certain new and useful Improvements-inponveyer Systems, of which the following sa specification.

My invention aims to provide an improved conveyer system by which the artlcles carried are easily certain stations.

The-accompanying drawings illustrate an embodiment of my invention.

Fig. 1 is a diagrammatic plan of the conveyer;-

Fig. 2 is a diagrammatic side elevat on thereof including the timing or controlling mechanism; I

Fig. 3 is' aside elevation of one of the timing devices;

Fig. 4 is a view of one of the timing devices in elevation and of part of another in section;

Fig. 5 is an enlarged plan of a deflector or removing device;

Fig. 6 is a front elevation thereof;

Figs. 7 and 8 are sections of the same on the correspondingly numbered lines of Flg 6.

Referring first to the diagrams, Figs. 1 and 2, the conveyer is illustrated as a belt 1 traveling in the direction of the arrow and carried on end rollers 2 and 3. Packages or other articles 4 to 14 are placed in turn on the belt at its left hand end and to be taken off at different stations indicated respectively at 15, 16 and 17 arranged below the belt; the first two at the sides and the latter at the end. The articles to be taken off at stations 15 and 16 are deflected from the line of travel of, the belt by removing devices or deflectors 18 and 19 respectively. Those which are not taken off at one of these points pass over the end of the belt to station 17. The system may be equipped with any desired number of stations, only three being shown for convenience.

The deflectors 18 and 19 are arranged to be moved out of the path. of the articles to permit themto pass to the last station, or .one or the other of the deflectors 18v and 19 is shifted to operative position just in addistributed and removed at" vance of the article or series of articles which is to be removed at the corresponding station. a

The operation of the deflectors is con trolled through a'timin device set at or near the starting point 0 the conveyer, say

to register with the position on the conveyer indicated by the dotted line .20, which may be marked in any suitable way on the apparatus. For each of the deflectors there is a pair-of push buttons or switches 21, 22. The switch 21 is closed when an article to be removed at station 16 arrives at the line 20. Suppose, for example, the article 7, when it arrived at the line 20 was found by the operator to be of the class described for station 16, and that the switch 21 had been closed at that time. The deflector 19 would be inoperative until the article 7 arrived at a point just in advance of the deflector, whereupon the latter would be shifted to operative position and would remove the article 7 and drop it at station 16., If the succeeding articles 8, 9 and 10 were to be taken off at the same station they would each have passed the line 20 without action by the operator and they would each in turn be deflected at station 16. If number 10 is the last of this lot, then when it passed the line 20 the operator wouldclose the switch 22 and after the article 10 had been deflected the deflector 19 would be moved to the inoperative position and subsequent articles would pass to the end of the conveyer and to station 17. Articles 4, 5 and 6, for example, will pass to the station 17 in this way. The deflector 19 being withdrawn article 11 will also pass. The classification of article 12 has already been determined and articles 13 and 14 will be classified as they arrive at the line 20.

The operation of the deflector is eifected .by means of solenoids 23 and 24, each of these being connected by a wire 25 passing to a battery 26 or other source of current connected by a wire 27 to thetiming device hereinafter described.

The other end of the solenoid coil 23 is connected by a wire 28 to a switch on the timing device adapted to be closed at a certain interval after the timing device has been set in operation. Similarly the oppois magnetized either permanently or by means of a coil 32 set in a groove in the periphery. These wheels are on a shaft 33 which is driven from a gear 34 driven by a pinion 35 on the shaft 36 which (Fig.-

4) is also driven from the conveyer. Thus the timing wheels 30 and 31 are synchronized with the conveyer Each'of the wheels, 30 and 31, is adapted to carry switch-operating devices which close a circuit through the corresponding deflector solenoid just as the article to be deflected arrives at the deflector. For the deflector 19 the switch-operating devices of the wheel 30 will be set in operative position at a point on its circumference which requires that the wheel turn through a distance corresponding to the distance from the starting line 20 to the deflector 19 before closing the circuit of the latter. For the deflector 18 the circuit closing devices will be set in operative position at a point farther advanced around the timing wheel so. as to require a correspondingly shorter time before it closes the circuit for this deflector; or the switch which closes the circuit may be located nearer the point at. which the switch-operatin device is fixed in operative position on the 'rim of the wheel. I

The wheel 30, for exam le, rotates in the direction of the arrow. T e wire 27 is connected with the wheel through a brush 3'7. Mounted'on a stationary segment 38 which surrounds apart of the wheel there is a switch arm 39 pivotally supported and held in an approximately horizontal position by the weight 40, the pivotal support being V connected to the wire 28; The switch arm 39 projects alongside the face of the Wheel. \Vhen the arm 39 is struck by a contact member 41 on the face of the wheel the wire 28 is electrically connected to the wheel which in turn is electrically connected, to the wire 27, so that the circuit is closed through the solenoid 23 which turns the deflector 19 to operative position. The con tact member 41 is one of a number of buttons or pins of magnetic material which'are used in turn, being held on the side of the wheel by magnetic attraction until they are forcibly removed therefrom. After the button passes the switch 39 which yields to permit such passage, it strikes a cam 42 which forces it out beyond the wheel and into a slot formed between the cam and an nmpsr outer ide 48. The buttons pass down the I slot, t e lower one restin on the end of'a plunger 44 ofthe solenoi 45, the opposite ends of the coil of which are connected by .wires 46 and 47 to the terminals of the switch 21 (through the battery 26). When this switch is closed .the plunger 44 of the solenoid is advanced and pushes the lowest an article on the conveyer to travel from the startin line 20 to the deflector 19.

On the opposite side of the wheel 30 the wire 29 is connected to a switch similar to that shown at 39 and there is a reservoir of contact buttons and a solenoid and lunger similar to those shown in Fi 3 and placed at the same angular distance from the switch which connects the line 29 with the wheel; this solenoid being connected by wires 49 and 50 to the terminals of the hand switch 22 (through the battery 26). When this switch is closed a button 41 is set on the wheel and in due time closes the circuit through the wire 29 and the solenoid 24 which moves the deflector 19 to inoperative position.

The deflectors may be of various designs arranged to swing on a horizontal or vertical axis or to slide into and out of position.

In Fig. 5 I have shown a deflector which operates with ease and certainty and which is locked in either position to which it may be thrown, until the operator unlocks 'it through the timing device. In this deflector, Figs. 5 to 8, the blade or deflector proper 19 is supported on trunnions51 above its center so that when released it will tend-to swing down quickly, the trunnions being carried in a frame 52 set obliquely to the conveyer. The solenoids 23 and 24 are mounted on this frame. The core 53 of the former is connected-by a pin and slot with a link 54 which is connected at its lower end with a bracket on the edge of the blade which is to be uppermost in the operative position of the blade. The core 55 of the solenoid 24 is similarly connected by a link 56 with the lower part of the blade, on the fare opposite the connection to the link 54. Now when the'solenoid 23 is energized its core will ull the blade to the upright position as shown in full lines, Fig. 7. The solenoid 24 being ino rative at the same time, its core 55 will rep and, by the play of the pin in the slot, it willcarry a lock 57 against the face of the blade. See Fig. 8. In this position the blade cannot move. When the blade is to be turned to the inoperative position the solenoid 24 is energized, the core 55 rises, first removing the lock 57 and then swinging the blade up to the horizontal position. inthis position, the core 53 is provided with a lock 58 which drops behind a stop 59 mounted on the upper face of the blade for;

this purpose.

Various-means may be provided for settin the timing deviceto, operate after the desired interval; and thesesetting devices may be actuatedeither by hand'as. described or by various automatic means cooperating with the articles as they are conveyed past the startin point. e

It will e seen that my improved apparatus can be worked by a sing e operator without confusion or loss of time in waiting for the articles to reach their discharging stations. .The contact memberson the timing wheel represent'in asense the articles on a belt. That is to say, the contact members become operative and start their: movement when the correspondin articles arrive at the starting line. An tween the travel of the first button (which at the .end of its travel renders a certain deflector operative) and the second button (which renders it inoperative) corresponds to a certain length of the belt carrying any number of articles in succession. 'If we assume that the switches 39 onopposite sides of the timing wheel are in register with each other and that the opposite solenoids 45 are likewise in register; then the arc of the timing wheel between the first switch-operating button 4:1 and the next button 41 on the opposite side will represent the length of belt which has passed the starting line in the interval between the bringing of these two buttons 41 to their operative positions. Thus the switch-operatlng buttons correspond to the first and last articleson a given belt, and the arc of the timing wheel between said buttons corresponds to the length of the belt carrying said articles and any number of articles between thefirst and last.

The conveyer is indicated as a single straight belt. ,But the invention may be ap plied to a great variety of conveyers other than belts, and to conveyers comprising a plurality of units and also toconveyers which carry the articles not only in a straight line but also in curved or broken lines. The controlling and deflecting mechanisms are not dependent on the type of cone veyer, except to the extent that the con-. trolling mechanism must be synchronized with the movement of the articles on the conveyer. I

Obviously a great variety of equivalents is possible for the contact members 41 which are shifted onto and off the face of the timing wheel. Any other. form of devices may be used which are set in operative position to control the electric circuit after a given period of time and any means for setting them in such operative positions and for To hold it locked ithe conveyer. p v v have described with great parthe difference be-' rendering them inoperative after the have acted on the electric circuit and until they are again set. v

Also instead of the timing wheel shown belts and various other devices may be use traveling at a rate proportional tothat of Though I ticularity of detail .an embodiment ofmy invention yet it is not to be understood therefrom thatthe invention is restricted to the particularcmbodiment disclosed. -Various modifications thereof in detail and in the arrangement of the parts may be made by those skilled in the art without departure from the invention as defined in the following claims. a I
