T0 all fao/tom t may concern.'

Be it known that we, SAMUEL NEWMAN, a citizen of the United States, and HENRY R. BoTHwELL, a subject of the King of Great Britain, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Ticket-Choppers, of which the following is a specification.

Our invention relates to deposit and collection receptacles; and itsy object is to receive tickets such as are used for fare oi' admission, especially the latter, and not only to prevent access of the attendant to the tickets after they are deposited, but also to cancel the tickets to prevent their use again after they have been removed from the receptacles.

Our invention consists in the combination of parts and in the details of construction and arrangement of parts as will herein be more fully` described and claimed.

In the drawings: p

Figure 1 is a vertical cross section through the upper part of a ticket chopper embodying our invention; F ig. 2 is a detail side elevation of adjacent parts of the canceling rollers; Fig. 3 is an illustration of one of the canceled tickets; Fig. 4 is a detail plan view of the mechanism; and Fig. 5 is a side elevation of the same.

As we prefer to construct our invention, it is incorporated in a receptacle of the usual design, which comprises an upright rectangular casing 1, having an op'entop 2, below which are barriers 3 and 4 inclined in opposite directions downwardly toward the middle of the casing, the barrier 4 underlapping` the lower end of the barrier 3 some distance therebelow, thus leaving a passage 5 for the tickets deposited through the open top 2. The tickets fall in'to a hopper 6 some distance below the barriers 3 and 4, and the barriers 3 and 4 are preferably made' transparent as shown to allow a clear view into the hopper G, while as is well known, the opposite sides, of which one side 7 is shown, may also be transparent to allow a clear view into the hopper 6. As ordinarily constructed, these devices have in their bot` toms suitable receptacles, such as the receptacle 8, onlythe top of which is here shown, and the tickets are allowed to pass from the hopper into the receptacle under the control of some rotatable device, operated by an attendant, who thus can cause the tickets to disappear from the view of the depositor as they are deposited, yet cannot have ready access to the tickets, the lower part of the casing having a door, such as the door 9, for removal of the receptacle, such as the receptacle 8, and this door being provided with a lock, the key to which is carried by the person who is responsible for the tickets after they have been used. As here shown, the casing has handles 10 at its opposite sides which are pivoted in brackets 11 lto drop down out of the way, but which may be raised for carrying the device about.

From the foregoing it will be seen that misuse of the tickets is guarded against, so long as no access is had to the receptacle 8. However, it being desirable to guard against misuse of the tickets by anyone who would have access to them in the receptacle 8, or after they have been removed therefrom, we provide means for effectively canceling the tickets incident to the operation of feeding them from the hopper 6 down to the receptacle 8. I

Our improved canceling mechanism com* prises a cylindrical roll 12, having annular grooves 13 in it at intervals from one end to the other, and another cylindrical roll 14 made up of disks 14, having teeth 15 around its periphery and collars 14 interposed bctween the disks, (Fig. 4,) spacing the disks apart, so that the teeth of the disks enter the grooves 13 of the roll 12. The formation of these teeth 15 is novel, and they have an improved action, in that they not only mutilate the ticket by punching through it as it drawn between the rolls, but they completely separate small pieces from the ticket,-in fact, making a complete perforation rather than merely an incision, and acting virtually in the same inanner as a punch and die, but without the necessity of careful relative arrangement of the male and female elements, as would be necessary to provide punches and dies `on rolls to actin this manner. Each tooth acts as ai punch, and the grooved roll acts as a die, but the grooves 13, being continuous around the roll, are capable of cooperating with the teeth or punches without any necessity of maintaining any exact relative arrangement of the two rolls. This action 1s rendered possible by forming each tooth with two distinct initial cutting edges l5 and (Fig. 2) which enter the material of the ticket successively and make incisions which will mark the ends a and a of the slots that are to be cut in the ticket A (Fig. 3). Between these cutting edges 15 and 15 the top of the tooth has parts 15a and 15b adjacent to the above two cutting points, respectively. The part 15 inclines slightly inward from the circle of the edges 15f of the teeth, while the part 15b inclines slightly away from a radial line through the edge 15 over toward the edge 15', thus meeting the part 15a slightly in advance of the edge 15 and forming an angle or crotch. This angle or crotch or radially innermost part of the advance side ot' the top of the tooth is adapted to enter slightly into the groove 13 of the roll 12 at the nearest approach of the tooth in the roll 12. From the edge 15 to the rear of the tooth, the top slopes down at a decided incline, merely leaving enough material in the rear of the tooth to al'l'ord the requisite strength to the part that has the cutting edge 15. Preferably, the several disks do not have their teeth alined transversely of the roll, but are so displaced relative to each otherl that the teeth are arranged helically on the roll, taken in transverse series, the pitch of the helix being relatively high.

With the teeth thus formed and thus positioned relative to the grooves of the roll 12, the ticket A will first be pierced by the advance cutting edge 15 and then by the next cutting edge 15, before the lateral edges of the parts 15a and 15b have advanced tar into the ticket, so that the material that is to be separated from the ticket will be held in place until the second cutting edge 15 has completely severed this end ot the material from the ticket. Then, with the tooth passing around onto the cen ter line of the two rolls, the lateral edges of the parts 15 and 15b will cut through the ticket.

The final action ofl the tooth on the ticket is for the inclined back part of the top of the tooth to extend the lateral incisions a short distance from the back end 1, of the slot, forcing out a short tongue a. This further mutilation of the ticket is not necessary, but at tlie same time is not undesirable. It is a consequence of the material left in the tooth to the rear of the cutting edge 15 which, as before stated, is to afford the proper strength to this part of the tooth.

To cause the two rolls 12 and 14` to turn together in opposite directions they are provided with spur gears 19 and 20, respectively, meshing with each other, and fixed to the respective rolls next to one of the side plates 18. There is a guard plate 21 on the inner side of the side plate 1S over these gears, and on the inner side of the other side plate 18 there is a small guard plate 22 covering the slight space between the ends of the rolls 12 and 14 and this side plate. The device is mounted in the casing 1, and the hopper G is so designed that the lower edges of its sides come over these guard plates and the lower edges of its ends come substantially over the center lines of the respective rolls or cylinders 12 and 14, and very close to the extreme outer surfaces of these cylinders. To prevent turning of these rolls or cylinders in opposite directions, one of the rolls has a ratchet means which, as here shown, consists of a pocket 23 fixed on the inner side of the side plate 18 adjacent to the periphery of and slightly below the horizontal center line of the gear of the roll 14, with the pocket opening toward the teeth of the gear, and having confined in this pocket a thick disk or very short cylinder 24 that may engage between the teeth of the gear 20. The interior of the pocket is so shaped that, when the rolls are turning toward each other and this disk or detent is carried up toward the top of the pocket, the disk may rotate, and ride over the successive teeth of the gear; but if attempt is made to rotatey the rolls in opposite direction, after this disk or detent 24 drops down to the bottom of the pocket it will bind between the toothof the gear and bottom of pocket and prevent rotation of the rolls.

For turning the rolls, a hand wheel 25 with radial arms 26 is fixed on a shaft 27 that extends in through the side of the casing 1 into a central bore 2S in the roll 14l and is screwed into a threaded part 29 of the bore 28 near the inner end of said bore. The threads'are pitched in such a direction that the shaft 27 will be screwed tightly into the roll 14 when the wheel 25 is turned to rotate the rolls toward each other, but will be unscrewed from the roll 14 when the hand wheel is turned in the other direction.

In order to insure that the tickets will be released from the rolls, and especially from the toothed roll 14 after they have passed between the rolls and be made to drop into the receptacle 8, fenders 30 and 31 are mounted in inclined positions on bars 32 and 33, respectively, extending across between the lower parts of the side plates 1S. The fender 30 extends up to within a short distance of the bottom of the grooved roll 12, and here has tines 34 projecting into the grooves 13 in the roll. The other fender 31 extends up to the bottom of the roll 14 and here has slots 35 through which pass the teeth 15 of the roll 14. The most important function of the tines 34 is to remove small pieces from the grooves 13, which pieces have been punched out of the tickets by the teeth 15, The canceled tickets and these small pieces or punchings will all fall into the receptacle 8.

On account of the arrangement above described, it'will be impossible for any ticket to pass from the hopper 6 into the receptacle 8 without passing between the rolls, and the shape of the teeth 15 will generally insure the engagement of a single ticket between the rolls so as to be drawn therebetween. However, since tickets may be deposited in strips of two or more, which may lodge across the open bottom of the hopper 6, or since, through inattention on the part of the operator, the tickets may accumulate above the rolls in such number that the entire mass of tickets could not be forced' between the rolls by the engagement of the teeth 15 therewith, we may provide a feed bar 36 which is provided with fingers 37 extending down from it at intervals `alonfr its lenoth and comino' between the disks 14 of the roll 14 if the feed bar is moved downward. To move thisfeed bar up and down at regular intervals, it is mounted on side arms 38 outside the side plates 18, each side arm having a fulcrum pivot 39 onthe outside of the adjacent side plate 18 near one of its upper corners. To allow this feed bar to work up and down. the sides of the hopper 6 are provided with slots 40 and the side arms 38 are curved along arcs struck from the centers of the pivots 39 for a distance somewhat greater' than the required swinging of the feed bar 36 around said pivots. Lugs 39 fixed on the side plates 18 near their tops, guide the arms 38 at these points. From the lower termination of this arc-shaped part the arm extends substantially radially upward to the pivot 39; however, being as here shown, slightly curved to avoid striking one of the screws 41 that hold the mechanism in the casing 1 at opposite ends of the side plates 18 at both sides, and also having` an upward projection 4Q with a slot 43 therein to afford means for connecting the arm to a pitman 44 which lies in between the arm 38 and the adjacent side plate 18 as permitted by a collar 45 interposed between .the arm 38 and the side plate to space the arm 38 outward. This pitman 44 has a pin 46 eX- tending out through the slot 43 in the upward projection 42 of the arm 38, and near its other end there is a pin 47 projecting into this pitman and mounted in the journal stud 16 of the roll 12' outward from the center of the stud. Thus the pitman has a short stroke upon the rotation of the roll 12, by which it communicates motion to the arm 38.

An S-shaped spring 48 has one of its ends looped around the pin 46 between the arm 38 and the pitman 44, and its other end is around a screw 49 in the outside of the arm 38, some distance down from the slot 43.

This spring normally holds the arm 38 in such position relative to the pitman 44 that the pin 46 occupies the upper end of the slot 43, so that the feed bar 36 with its lingers 37 will be pulled down amply far to cause the fingers to force the tickets between the rolls, and this spring 48 is strong enough to hold the arm in this position relative to the pitman under any ordinary resistance of the tickets. However, should a considerable mass of the tickets accumulate as before alluded to, the spring 48 will yield, and the arm will simply press down on the mass of tickets under the pressure of this spring, and hold the mass of tickets down against the teeth, allowing the teeth to disengage the tickets from the mass singly or in such small numbers as the teeth are able to pass the tickets between the rolls, thereby avoiding clogging of the machine under all conditions.

lVhen any per 6 which between the larticle is dropped into the hop- 1t is desired shall not be passed rolls, but which should be removed therefrom, it is highly desirable to afford convenient access to out removing the barriers 3 and 4 or otherwise disassembling the device. Therefore, to permit this, we provide an opening 50 in one side of the casing 1 which is normally closed by a door 51, provided with a lock 52, opened by a key This key 53 should not be inthe possession of the attendant, since a primary purpose of the device .is to prevent access of the attendant to the tickets deposited; although, of course, it will be understood that it is not so convenient for the attendant to remove the tickets from the hopper 6, because such action would be liable to be noticed by the depositors of the tickets, among whom it is generally understood that the tickets should be made to disappear from the hopper down into the lower end of the device as fast as they are deposited. This key may be in the possession of a person responsible for the tickets, who may furnish the key when required to remove any article from the device. 0f course, such incidents are of rare occurrence,
