8 Claims.

The invention is coiioerned with a combined barrier and article dispensing means each of which is interrelated with and dependent upon the other for its control and operation. As specifically embodied in the machine hereof it comprises a turnstile which mas operation delivers a ticket or check in a position to be removed by a patron about to pass through the tuins'tile, the removal of the check being instrumental in unlocking the turnstile permitting passage therethrough, and operation of the turnstile by the person in passing through operating to feed forward another check where it is in a position to be taken by the next succeeding patron. A typical use is in connection withrestaurants of a character where a customer receives a* check upon entering upon which is subsequently punched the amount of the food purchased.

The invention comprises an improved machine of such general character and purpose which is compact in construction and dependable in operation, and aiiords a maximum of convenience and ease of operation to the customer. Various novel features are coordinated and so' related as to produce the improved" results. The character of these will appear more iull yiromthe detailed description of the illustrative machine disclosed herein but certain features will be noted in general as a preliminary matter.

The machine is particularly Well adapted to dispense checks from a continuous strip. When a patron approaches the device the leading end is exposed in a convenient position but is: intact with the strip. A light pull, however, on the end of the strip causes a spring urged knife to snap across the strip in a quick shearing operation which severs the forward end portion and it thereupon becomes a freely removable article. In the particular example this article is a check such as is used in restaurants. This same action positions certain parts whereby the pressure then applied to the turnstile arm by the" patron in his normal continued advance serves positively to withdraw a theret'ofore'efiective turnstile locking means.

The continued advance of theturnstile operates a mechanism for advancing the stripto present the endportion for the next patron. This mechanism is associated with a pressure member means for centering the turnstile in home position and takes advantage of the intermittent cyclic operation ofsu'ch me'mbeii topnoduce'intermittent movements or thejcheck ieedingand dispensi-ng elements in a as op'r'iattiined relatim to" each other andtotheturnstile; For ex- 2 ample, the arrangement is such as to ensure that the shearing knife is withdrawn and in latched position free of the path of the check strip prior to initiating the forward feed of the strip.

The arrangement of the machine and its functional parts are such that the patron may proceed through in a normal unbroken stride without being subjected to the annoyance of bumping against a locked turnstile; and at the same time the arrangement renders it impossible as a practical matter for the patron to obtain more than one check Without resorting to' conspicuous distorti'ons.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be exemplified in the construction hereinafter setforth, and the scope of the invention Wili be indicated in the claims. 7

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a view in perspective of the complete housing embodying the associated turnstile and check delivering means;

Fig. 2 is a top plan view thereof looking down on the internal mechanism with the main cover of the casing removed; 7

Fig. 3' is a view looking from the right inFi'g. 2, with most of the operating mechanism omitted, showing the rotatable turnstile head;

Fig. 411s also a view looking from the right in Fig. 2 taken on approximately the section: i 3';

Fig. 5 is a' view in elevation of the check strip feeding means;

Fig. 6 is a detail view of the check severing knifeand associated mechanism looking from the right in Fig.5; with the casing broken away; and

Fig. '7 is a detail View similar in general to Fig. i, but with various elements omitted and showing particularly the mechanism in a position torelea'se the turnstile lockingpawl.

As shown generally in Fig. 1, the mechanism is located'in a casing H3, having a removable top cover H, and a movable side plate I 2; giving access to'the check strip magazine" H3; The turnstile is of the type having three arms l5 rotatable about an axis at to the horizont'aland vertical. The armsare secured ina'hu'b l6 which in turn is fixed to a'shaft" I1, having bearings-in the lower plate I? and upper bracket l' as'shown particularly in Figs. 2 and 3; A rotatable" head 2c is alscsecuredtc theshaft' it. The turnstile aoispsi's 3 mechanism and check delivering means are of a character and are so associated as to form a generally compact arrangement requirin small space and adapted to present the leading check C in an appropriate and convenient position relative to the effective barrier arm l5a whereby the patron upon approaching naturally observes and picks up his check substantially in advance of contacting the barrier arm l5a. In this connection it will be noted that the arms of the turn-'- stile rotate downwardly and inwardly underneath the operating mechanism.

The turnstile is provided with suitable means for centering the arm mechanism in home position. As specifically shown this means comprises three studs 23, located on the upper surface of the plate and spaced at equal angles thereon corresponding to the spacing of the arms l5. Each stud carries a lower roller 24 and an upper roller 25. The lower rollers are adapted to be engaged by an arm 26 integral with a multiple arm member 21, the arm 28 of which has attached thereto a relatively strong tension spring 29 adapted to urge the member 21 and its arm 26 in a clockwise direction as shown in Fig. 2. A stud 30 fixed in the frame plate l8 provides a pivotal support for the member 21.

The turnstile head 20 is provided with a releasable locking pawl 3!, the operation of which will be later described more in detail, and also with a ratchet pawl 32 spring pressed into engagement with the lower notched portion 33 of the edge of the plate 20, adapted to prevent reverse movement of the turnstil and its plate 29, that is, to permit clockwise rotation in Fig. 2, but to prevent reverse rotation thereof.

Certain features of the invention are suited for association with check feeding means of different types as e. g. either from a stack of individual checks or from a continuous strip but the combination here employed of a continuous strip feeding means exhibits particular advantages as will appear. The check strip feeding means is shown generally in Fig. 2 at 35, the details appearing more in Fig. 5. In general this mechanism lies in a vertical plane, the axis of the turnstile mechanism being at an angle of thereto. As heretofore noted, the magazine l3 for the check strip is located in the bottom of the turnstile shell. The strip 36 may be of standard form such as that used in restaurants, each individual check having printed amounts thereon to be punched. The main supply may be on a reel or in accordion form as shown. The strip is provided with standard small openings 36a at regular intervals between the successive checks, which openings are employed in the feeding of the strip as will be described. The leading end of the strip 36 proceeds upwardly from the magazine through an arc shaped channel 31, comprising two spaced guide members 38 of sheet metal, U-shaped in cross-section, with the strip edges extending between the fingers of the respective U-sections as appears in Fig. 6. From the channel 31 the strip proceeds outwardly across the path of a knife 39 which operates adjacent the opening 4| in a bearing plate 42, underneath a freely rotatable roller 43, and out the opening 44.

The leading check C in normal position of the machine, extends a substantial distance beyond the face of the casing whereby it may be readily grasped by an entering'patron.

The knife 39 is provided with an upper slot 41 adapted to receive a stud 48, secured in the plate 42, the stud being provided with a block 48:: adapted to maintain the knife 39 against the surface of the plate 42. The lower end of the knife is similarly guided against the plate 42 by a screw bolt 59 secured in the plate 42, the knife 39 having a vertical slot 5| for receiving the bolt 50. The knife 39 is normally urged upwardly by a strong spring 52 hooked to a stud 53-, secured on the lower end of the knife, the opposite end of the spring 52 being connected to the fixed post 48. The knife 39 may comprise a single piece but the present form provides certain advantages in constructing the end blade portion 39a as a separate part whereby it may be removed from the body portion for sharpening or replacement, and if desired, may be of different material. The bottom edge of the removable blade portion has a notch to receive the spaced tongue portions 39b of the body section. The section 39a is secured to the body portion by spring strips 54 which are fastened to the body portion by screws 54a, the upper ends having detents or buttons 54b which snap into depressions in upper blade section 39a. Additional part length spring plies 540 may also be employed to give added spring tension, the spring effect serving to urge the blade against its complementary shearing plate 42. It will be noted that the shearing stroke of the knife is derived altogether from its spring 52, and is independent of the force applied to the turnstile arm, or the speed with which the arm moves. The knife always exerts the same force for cutting off the ticket.

A bell crank 55 is mounted on a stud 5G threaded into an ear 42a on plate 42, and is adapted to oscillate thereon in the plane of the paper in Fig. 5. The bell crank includes a short arm 55a provided with an upper hook end adapted to engage over a lug 51 on the knife, as shown particularly in Fig. 6. The other arm 55!) of the bell crank carries a slidable latch 53 provided with a finger 58a adapted to engage in a hole 36a of the check strip, the slidable latch being normally urged radially outward by a spring 59. The outer arm part 55b has a right angle offset with respect to the base part 55 so as to bring latch 58 in the plane of the strip openings 36a. The bell crank 55 is spring biased in a counter-clockwise direction by a spring 60 secured at one end thereto, the other end being secured to a post 6! located on the side plate 62 of the frame construction.

The cycle is initiated and the mechanism released by a patron grasping the exposed check C and pulling thereon, which requires but a very light force sufiicient to overcome the relatively light spring 60. Pulling outward the check a short distance to the point where the first opening 36a in the check strip is opposite the shearing edge of the knife 39 rocks the bell crank 55 a corresponding distance, which releases the arm 55a from engagement over the lug 51 of the knife 39, whereupon spring 52 snaps the knife 39 upwardly, shearing off the leading check C.

The same operation serves through further linkage which will now be described to unlock the turnstile. Integral with the knife 39 is a pin 65 which strikes a right angle lug 65 on the bell crank 61 mounted to oscillate about a pin 68 secured in the side plate 62 of the frame. Upward movement of the blade and its pin 65 accordingly rocks the bell crank 61 counter-clockwise, pulling connecting link 69 to the right. This link 69 is connected to a latch arm 10 pivoted on a fixed pin H as shown particularly in Fig. 2. The latch arm is normally spring urged in a counter-clockwise direction (in Fig. 2) by a coil spring on post H, and has a tooth 16a adapted to receive a complemental tooth on the lever I2 which is urged by a spring I3 in a clockwise direction but is normally held in the latched position shown by the lever I0. Mounted on an arm I6 of the member 2'1 is a pawl releasing member 11. The member 11 is. adapted to swing about its pivotal support I8 in a vertical plane, but is bodily carried on arm 1-6 as described. The lever I1 has an upstanding right angle lug part I9 which occupies a position in a notch 80 in the lever I2 and the lever I2 in normal latched position holds the outer end of the lever 11 in an elevated position as shown, for example, in Figs. 2 and 4. When, however, the arm I2 is released from the latch arm I0 permitting lever I2 to swing clockwise in Fig. 2, under the pressure of its spring, this permits the lever 11 to drop to a position as shown in the detail view of Fig. 7 where it is in a position, upon movement of the turnstile, to engage a pin 82 on the pawl 3I, rocking pawl 3! to swing it out of its notch 83 in the turnstile head plate 20, as will be shortly described in more detail.

Assuming now that the leading check C has been pulled and the knife 39 has chopped it off and the linkage connected thereto has been operated, including the release of the latch arm 7 I0 as described, the turnstile may now be operated by the patron, pushing on the arm Ilia. Referring back to Fig. 2 again, as the turnstile, including the plate 20, starts to rotate in the direction of the arrow 86, in Fig. 2, the right hand roller 24 engages the arm 26, rocking the member 21 in a counter-clockwise direction at a relatively rapid rate so that before the plate 23 has rotated more than a short angular distance, the lever 11 engages pin 82 on the locking pawl 3! swinging the pawl out of its notch 83. The notch 83 in the plate 2!] is of a length in the peripheral direction of plate 23, to provide a substantial clearance at the outer end of the pawl 3I, such as to permit sufiicient initial rotation of the plate 20, whereby the pawl is swung out of its notch, before it is engaged by the end shoulder of the notch 83. It will be observed that the force for actually withdrawing the locking pawl is supplied by the patron at the turnstile arm.

Continued rotation of the turnstile arm for the, necessary 120 serves to feed forwardly the check strip 36 through means which will shortly be described, but for the time being, the description will be confined to the further operation of the mechanism appearing in Fig. 2 and its restoration to the locked position there shown. As the plate 29 continues in its rotation under pressure applied by the patron, the upper roller 25 on the stud 23 at the right engages the cam arm 88 on the lever I2, rocking it counter-clockwise against the force of its spring which permits the .latch lever I0 to swing back into the position shown, wherein it holds the lever I2 in its latched position with the lever I! in its elevated position free of pin 82 on looking pawl 3I. A spring 89 leading from a fixed frame part to a pin 99, in-

tegral with the pawl 3 I., normally urges the pawl 3| in a counter-clockwise direction in Fig. 2, and when the arm 1! is in its elevated position and the turnstile has progressed to its next home position, the pawl 3| drops into locking engage- I ment with the next notch 83 in the plate 23. It

will be understood that when roller 2 I on the stud 23 at the right passes dead center position with respect to the pressure arm 26, the latter under the pressureof heavy spring 29, serves to urge the turnstile forward automatically and to center and bring it to rest at its next home position.

The turnstile mechanism will preferably have associated therewith a suitable shock absorber means adapted to ease it into home position without substantial shock or noise. Such mechanism. however, is not specifically disclosed herein since it forms no part of the present invention. Also, a suitable register or meter means will preferably be employed to indicate the number of operations of the turnstile and accordingly, the number of patrons passing therethrough.

Referring to Fig. 5, in particular, the means operated from the turnstile for advancing the check strip will now be described. This comprises an oscillatable arm 9| mounted on the main shaft 92 supported at one end in bearing bracket 93 and at the opposite end in the vertical frame plate 52. Integral with arm 9I is a short arm 94 arranged at an angle thereto to which is connected a link 95, the opposite end of the link being connected through a suitable eye member 96 to a pin 91 on the lower arm 98 of the oscillatable member 2?. The outer end of the arm 9! carries a feeding dog I03 provided with a projection IiH adapted to engage in a hole 36a of the check strip. The dog I03 is normally urged by tension sprin I82 in a counter-clockwise direction, in Fig. 5, to cause it releasably to engage in the hole of the check strip. The shape and pivotal support for the dog I03, however, is such that when the check strip is normally advanced the short distance heretofore described to release the cutting knife 33, the check strip is free to move forwardly and cam the dog I00 from the strip opening 33a and permit the free advance of the strip the necessary small distance. Assuming now that the turnstile is being rotated in the forward direction, this pulls rod 95 to the left, swinging the arm 9| downwardly to the position shown in dotted lines, in Fig. 5, and then, as the advancing roller 24 on the plate 23 passes its midpoint or dead-center position with respect to the arm 23, the member 21 rotates backwardly, that is, clockwise, in Fig. 2, to the position shown which returns rod 95 to the right, swinging the arm 3| upwardly from the position shown in dotted lines, the tooth Isl on the dog I03 engaging in a hole 36a in the check strip, advancing it the distance of substantially one check to the position shown in Fig. 5.

Prior to the advance of the strip in the manner just described, the latch 58a on arm 5512 has been released from its opening 36a in the strip by means of a small lever I04 pivoted on the projecting finger Ifla of the arm 5%. This is effected by the pin 65 fixed to the knife 39 in its upward shearing movement, engaging the lug 66 on the bell crank 67 and rocking it counter-clockwise in the manner heretofore described, which in additlon, causes the lug 66 to engage the right end of lever IIM, rocking it counter-clockwise on its pivot, which results in the opposite end of the lever engaging a right angle lug 581) on the silda'ble latch 58, pulling the latch radially inward with respect to the arm 55b, and releasing the tooth 53a from its opening 33a in the check strip.

The means for restoring the knife to its retracted latched position comprises a second bell crank I35 mounted on the main shaft 92 having anupper arm with a finger I 06 operable in a notch I31 in the lower left edge of the knife 39. as itappears in Fig. '6, and a downward-1y extending arm I08, to which is secured a rod I09, the opposite end of the rod having an eye adapted to be received on the pin 91 on the arm 98 of the oscillatable multiple arm member 21, the rod 95 being also secured on the same pin as heretofore described (see Figs. 4 and '7). In the initial movement of the turnstile from the home position, both rods are moved to the left. The rod 95 as heretofore described initially swings downwardly the strip feeding arm as on an idle stroke. During this same initial period, the movement of rod I09 to the left to its broken line position indicated in Fig. rocks the bell crank I05 clockwise and the finger I06 engages against the shoulder IOIa of the notch I01 of the blade 39 (Fig. 6) moving the blade downwardly which permits the finger on the arm 55a of the bell crank 55 to move clockwise into latching engagement with the lug 51 on the knife 39 and to restrain it in such locked position. This retraction of the blade, it will be observed, occurs prior to the upward feeding stroke of the strip advancing arm BI so that the knife is withdrawn and there is no obstruction to the advance of the check strip.

The connection of the rod I09 through pin IIO to the lower arm I08 of bell crank I05 preferably includes an elongated slot in the end of the rod whereby one part may have a little extra travel with respect to the other if required at some point in the cycle, depending on the timing, and relation of the different elements. In this connection it may be noted that the upper arm having the finger I00 is connected by a tension spring I I I to a fixed part of the frame, such as the post 60. As the parts are arranged, when knife 39 is released, the finger I06 is free to travel a small distance upwardly if and when it is engaged by the shoulder I0'Ia on the knife by reason of the above described lost motion connection between the rod I09 and its pin I I0 fixed on the crank I05.

A suitable means is preferably embodied to prevent the check strip from moving reversely as for example under the frictional drag of the arm 9|, in its downward swing. The means here provided comprises a small blade II3 shown in the upper part of Fig. 5 mounted on the stub shaft H4 and urged against the strip in the counterclockwise direction by spring II5 connected to a finger I I6 integral with blade I I3. The outer end of the blade I13 is provided With saw teeth II! and the angular position and character of the blade I I3 are such as to permit the check strip to advance freely in the forward feeding direction but to clamp against the strip upon any tendency of the strip to move in the reverse direction.

A brief rsum of the operation is as follows: an approaching patron, in moving forward grasps the check C, giving it a slight pull which swings forward the arm 55b, releasing arm 55a from the lug 51 on the knife 39, permitting the latter to snap upwardly under the force of its spring 52 and the end portion C of the strip is severed through one of the openings 36a and is immediately freed and the patron proceeds without hesitation forwardly against the arm I5a, of the turnstile, advancing it. As the knife snapped upwardly it operated through pin 65 thereon to rock bell crank 61 and pull latch arm 10 to the right, releasing pivoted lever I2 which permitted arm I! to drop to its lowered position. As the patron continues advancing through the turnstile, the rocking of the multiple arm member 21 through the pressure arm causes the arm 11 to engage pin 82, rocking pawl 3I from its notch in the turnstile head plate 20, permitting continued rotation of the turnstile to the nexthoni position as determined by the pressure bar 26 and the locking pawl 3|.

In the meantime, the rocking of the member 21 in the initially counter-clockwise direction pulls rod I09 to the left, which causes finger I06 on the bell crank I05 to lower the blade 39, and the spring 60 causes the bell crank 55 to rock counter-clockwise and the arm 55a to latch over the lug 51 on the knife, holding it in its latch retracted position. During this operation the feeding arm 9| has swung downwardly in Fig. 5 and in the continued rotation of the turnstile when the multiple arm 2'! moves clockwise into the position shown, rod will move back to the right, swinging upwardly arm 9|, advancing the strip 36 the distance of approximately one check. At the termination of these operations the turnstile is again in its locked position and another check is presented at the opening 44 ready to be pulled out and taken by the next succeeding patron.

It will be understood that when the term check is employed in the specification and claims, it is not limited to the articles employed in restaurants for indicating the amount of a meal purchased, but may comprise any form of ticket or article which is capable of being dispensed in the manner described:

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
