COIN-CONTROLLED VENDING MACHINE.

Application filed November 5, 1925. Serial No. 67,078.

The invention relates to a Vending machine and relates more particularly to coin controlled vending machines of the selective type wherein the articles are contained in a plurality of compartments, any one of which may be selected by the prospective purchaser and moved into alignment or registry with a delivery opening normally closed by a sliding door, the opening of said door to permit the article selected to be removed from the machine being permitted and controlled by the insertion of a coin in a collection receptacle, thereby permitting the operating handle to be actuated.

An important object of the invention is to provide a coin controlled vending machine of the character described comprising a rotary drum having a plurality of radially disposed pockets or compartments adjacent its periphery, said compartments being 1n alignment with corresponding windows in the drum casing for inspection by prospective purchasers, said drum being freely rotatable by a centrally disposed handle to bring any desired radial compartment into registry with a single dispensing door aperture in the drum casing prior to the coin controlled operation of opening the door.

A further object of the invention is to provide a vending machine of the character described so constituted as to cooperate with a coin controlled mechanism to permit the dispensing door to be opened only after the insertion of the proper coin.

A further object of the invention is to provide a machine of the character described which is incapable of actuation except upon the insertion of the proper coin together with means for automatically returning to the purchaser any undesired coin of any size capable of being inserted in the reception slot provided for the purpose.

A further and important object is to provide a vending machine including a rotary drum having radial article receiving compartments any one of which may be freely moved into registration with a normally closed door, mechanism being provided to permit said drum to be freely rotated only 7 while the door is closed. The opening and closing of said door is controlled by suitable mechanism which is in turn controlled by the operating handle to move said door successively to open and closed position. It is contemplated in this regard that when the door is open the coin slot is obstructed to prevent the insertion ofa coin therein, said ohstruction being automatically removed when the door is closed.

A further object of the invention is to provide a machine of thecharactcr described in whichsimple and effective mechanism is provided to return the opened door to closed position by a reverse movement of the oper ating handle to render the machine in position fora succeeding sale. Vhile said door is open the drum is locked against rotation in either direction to bring a succeeding compartment into registry with the door aperture.

A further object of the invention is to provide machine of the character described in which the contents of the compartments of the drum may be clearly distinguished and readily selected with a minimum of effort on the part of the purchaser. I 7 Either letters,

numbers, colors, signs, trademarks or names may be used in conjunction with the present invention to designate the contents of the drum pockets. And if desired an index or list of the various articles may be printed or otherwise displayed on the front of the machine for the convenience of the purchaser to enable him to bring the desired article immediately into registration with the door aperture. It will be understood in this regard that the machine is designed to dispense various articles of widely varying and unrelated character. For instance one compartmentmay contain razor blades while another compartment may contain a tooth brush, while still another compartment may contain any other desired article. The machine is further designed to dispense san'dwiches, pie and cake which may be put up in convenient paper wrappers, the particular kind of sandwiches, pie or cake being indicated on the wrapper for the convenience of the purchaser. The radial compartments containing the different varieties of articles to be sold may have tabs or indicia thereon to visibly display to the purchaser the nature of the article contained in each compartment.

A further object of the invention is to provide a vending machine of the character described which may beeconomically manufactured and assembled, with most of the Working parts die-pressed, said parts being capable of being assembled rapidly and providing a machine which is extremely durable in'its nature, as well as adequately protected against pillage by unscrupulous and unauthorized persons.

With such objects in view, as well as other advantages which may be incident to the use of the improvements, the invention consists in the parts and combinations thereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of the invention.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical eflect, without limiting the improvements, in their useful applications, to the particular construction which, for the purpose of. explanation, have been made the subject of illustration.

Fig. '13 is an enlarged exploded perspective view looking toward the rear face of the casing, of certain of the mechanism illustrated in Fig. 4: and which provides for opening and closing the door locking the drum when the door is open. and permitting free rotation of the drum when the door is closed.

Referring to the drawings the machine comprises a support 1 which may be a frame or bracket formed preferably of cast metal. having a central hub portion 2 and radially extending legs or brace members 3. The support 1 is provided with a circumferential flange i to which is riveted or otherwise secured a circular housing or wall 5. Preferably integrally formed with the frame member or support are a plurality of cast metal bosses 6, one of which may be formed at the outer end of each of the radially extending brace members or legs 3, and said boss portions are centrally apertured to have rigidly secured therein a'corresponding number of forwardly extending bars or bracing elements 7. The latter project forwardly of the circumferential wall 5 and are formed with reduced for ward extensions 8 having enlarged headed portions 8 for a purpose to be described. The radially extending legs 3 are preferably provided on their rear faces with integrally formed cast metal bossportions 9 which are centrally apertured as at 10 and by means of which are frame member or support 1 may be removably secured against, the wall or counter or any desired location for the machine. The hub portion 2 of the frame member 1 is centrally apertured to have rigidly secured therein a forwardly projecting central hollow stud shaft 11.. One of the forwardly projecting members 8 on the ends of the radially extending legs 3is or maybe provided with an upwardly projecting apertured locking lug 12 which may be permanently secured to the arm member 8 as by rivets or by any desired securing means.

The rotary drum or container 13 consists of arear wall 1 1 centrally apertured as at 15 for the projection therethrough of the central stud shaft 11 of the frame member 1. The drum comprises further an outer peripheral wall 16, an intermediate peripheral wall 17 and a depressed outwardly flanged front wall 18 to which the intermediate peripheral wall 17 is soldered or otherwise secured. The space between the described outer and intermediate peripheral walls 16 and 17 is provided with a plurality of radially extending partition walls 19 of any desired number, forming radial compartments 19 and which partitions serve to reinforce and space the said peripheral walls; the radially extending walls being secured to the inner and outer peripheral walls by downturned ears or lugs 20 extending through corresponding slits or apertures in the inner and outer peripheral walls. V v

The depressed front wall is provided with an enlarged central aperture 21 corresponding to and in horizontal alignment with the central aperture 15 in the rear wall 14 of the drum. Means for providing a rigid rotary support for the drum are provided in the nature of aspider member 22 having radially extending legs 23 provided with centrally apertured bosses 24 at their ends. The spider member is further provided with an inwardly extending preferably integral hub portion 25 adapted to project through the central aperture 21 in the depressed front wall 18 of the drum. \Vhen the device is assembled the apertured ends of the radially projecting legs of the spider member are designed to coincide with a corresponding number of apertures in the depressed front wall of the drum, a suitable threaded nut 26 being welded to the rear side of the front wall 18 so that the spider may be rigidly secured to said front wall by means of screws 27 or other fastening means. A flat gear 28 having peripheral teeth 29 is provided and having countersunk apertures 30 near its periphery,'which latter coincide with the apertured legs of the spider member 22 to permit the gear to be rigidly secured to the drum with the spider, by means of the described screws 27 or other fastening means. The gear 28 is provided with a central aperture 31 and a second pair of diametrically opposed apertures 32 adapted to receive corresponding projections 33 formed on the spider member 22, and which arrangement insures that the gear 28 can only be assembled on the spider and drum in a single definite predetermined position. The fiat gear 28 is further provided on its forward side with a pawl 34 constituted of a bell crank lever and pivoted at 35 to the gear and having one end thereof normally pressed in contact against a stop 36 on said gear by means of a coil spring 37 secured to said pawl and having its other end secured to a projection 38 on said gear. This arrangement presents the opposite end 39 of the pawl in a certain predetermined position with respect to the central aperture 31 in said gear, and the pawl may be swung on its pivot against the tension of the coil spring 37 under conditions to be described during the operation of the machine.

The drum 13 is designed to be housed within the peripheral wall 5 of the frame 1 and the central hollow stud 11 of said frame is adapted to project through the centrally opposedapertures in the rear and front walls of the drum and through a central aperture 40 in the spider member 22 to provide a journal bearing support for the free rotation of the drum on the frame 1. The hubportion 2 of the frame 1 provides an abutment to limit the inward movement of the drum 13 on the central hollow spindle 11 of the frame 1.

The machine further comprises a front casing member .41 having an inwardly projecting preferably integrally formed peripheral flange 42 and a plurality of outwardly pro jecting integrally formed ears 43 which are suitably apertured as at 44 to receive the headed extensions 8 of the forwardly projecting arms 7 secured to the periphery of the frame 1. The construction of the apertures in the ears 43 of the casing is such that when the later is assembled on the frame to house the drum the casing is secured in position by a short rotary movement of the later which locks the headed extensions 8* in the reduced portions of the apertures 44'. One of the ears may be apertured to correspond with the apertured lug 12 secured on one of the forwardly projecting arms of the frame. The machine is locked in assembled position by means of the padlock 45 having its hasp projecting through the aligned apertures of the ear 43 of the casing and the lug 12 secured to said frame. The casing member 41 which is preferably of cast metal, is provided with a depressed door receiving por tion 46 apertured as at 47 to provide a door opening. The door aperture is designed to be normally closed by means of a sliding door 48 constituted of a door frame 49 having a transparent panel carried thereby. The door frame terminates in a depending extension 50 pivoted at 51 to the upper end of a main door operating lever 52, the later being pivotally secured as at 53 to the inner face of the casing. The main door operating lever is provided with an elongated recess 54in which is seated for limited lateral movement a pin or projection 55 on the lower end of the depending extension 50 of the door frame 49. Through the actuation of mechanism to be hereinafter described the door is designed to be swung on the pivot 53 to open and closed positions to expose and obstruct the door aperture 47 in the casing. Suitable guides 56 and 57 are provided and are secured to the casing by screws or fastening means 58 and 59 threaded into suitable projections 60 and 61 preferably formed integrally with the inner face of the casing. The upper guide member 56 is elongated and olfset to assist in maintaining in position one or more circular packing sections 62 to be described. The construction of the door lever is such that limited pivotal or swinging movement of the door and its extensions 50 relative to the main door operating lever 52, is obtained, thereby cushioning the door and insuring against possible damage to the mechanism of the machine when the door is swung to open and closed position. This constructionalso permits a snug fit between the top portion of the door frame and the inner peripheral flange 42 of the casing. The casing is further provided with a pluralitv of radially disposed window apertures '63 corresponding in number to the radial compartments 19 of the drum. The window apertures may be-elosed by means'of glass sections fitted between radially extending integrally formed webs 64 on the inner face of the eas-' ing; the outer edges of the glass sections may be further secured in place by means'of a peripheral inturned flange (55 secured to the inner peripheral wall of the casing. The inner ends of the glass sections are or may be secured in place by one or moreof the circular packing members 62 formed of rubber or 3 or closed position.

fabric covered wire, and fitting against the outer faces of a plurality of projections 66 integrally formed on the inner face of the casing, and the packing members are secured in place by a corresponding number of clips 67 secured as by screws 68 to said integrally formed projections.

A coin control housing 69 is preferably i11- te rally formed on the front face of thecasing and having an apertured boss portion 70 for the projection through said casing and said coin control housing of a central oper ating shaft 71 having an operating handle 72 rigidly secured on the front end of said shaft. The coin control housing 69 is provided with a removable cover portion 73 having a centrally disposed coin slot 74 and the cover portion is further provided at each end with a depending spring leg 75 apertured at their lower ends to receive therethrough corresponding locking projections 76 formed on the casing on the inner opposed walls of the coin control housing. The cover portion 78 is further provided with a sliding member 77 having an elongated aperture 78 to receive a pair of aligned projections 79 on the cover portion, and the slide member is further provided with a depending recessed portion 80 on an opposed portion or tab 81 to cooperate with the coin slot 74 in said cover. The re cessed portion of the sliding member is designed to cooperate with the door of the machine to alternately obstruct or clear the coin slot according to whether the door is in open The cover portion is further positioned on the top of the coin control housing by means of opposed projections 82 formed on the housing and which are designed to' enter corresponding apertures 83 in the cover portion. It will be apparent from the foregoing that spring locking means are provided for the cover of the coin control housing by means of which the former is normally locked in position by the depending spring legs 75, the cover however may be removed by releasing the spring legs from their projections on the interior of the easing, thereby exposing to View for repair or replacement, the interior of the coin control housing. The construction described permits the coin control to be easily accessible to authorized persons and renders it unnecessary to completely dismantle the machine in the event that repairs are necessary or that the coin slot and control mechanism becomes obstructed by a spurious coin.

The coin receptacle consists of a box 84 adapted to fit against the lower side of the coin control housing to receive the coins passing through the coin control during the operation of the machine. Means are provided to securely lock the coin receptacle in position on thefront of the machine, to permit the same to be removed and replacedby an empty receptacle by anauthorized person by means of the single key lock indicated at 85. These means consist of a cast rib or projection 86 on the front of the casing corresponding in shape but slightly larger than the periphery of the coin receptacle. The latter is adapted to nest or fit within said rib and the coin receptacle s4. is provided with preferably integrally formed projections 87 adapted to register with corresponding apertures or cutaway portions 88 in the casin The coin receptacle is locked in position by turning the key in the lock 85, and is removed in a like manner, The cooperation of the projections 87 with the recesses 88 prevents the coin receptacle from being tilted or otherwise removed from within the enclosing rib 86 by means other than by turning the key in the provided lock 85. The coin control housing is further provided with an aperture 89 communicating with the coin slot-74 in the top of the housing and by means of which improper or spurious coins are returned to the purchaser without affecting the operation of the machine.

If desired each radialcompartment of the drum may be provided with a tab 133 on which may be displayed the kind of article within the compartment, said tabs being visiblc through the transparent windows of the machine casing for the convenience of the purchasers. The tabs 133 may be suit-ably hinged within the several compartments so as not to obstruct the removal or insertion of an article within said compartment.

The coin controlled mechanism contained within the housing 69 of the casing, may be of any desired or suitable type andis designed to be operated by the main central shaft 71 and the operating handle 72 keyed to the outer end of said shaft. A coin mechanism may be utilized such as is fully described in my co-pending application, Serial No. 464,7 7 0, filed April 27, 1921 for coin controlled device. An examination of the coin controlled mechanism described in my said co-pending application will aid in a complete understanding of the present machine.

A drum locking lever 90 is pivoted at 91 to a suitable hub portion on the inner face of the casing and having its outer end normally maintained against a stop projection 92 secured to the casing, by means of a coil spring 93 secured at one end to said locking lever and having its other end secured to a pin or projection 94 on the inner face of the casing. The locking lever 90 is provided with an integral upstanding arm 95 having an inwardly extending locking projection 96 thereon, the

latter serving as a journal support for a friction roller 97 loosely mounted on said projection. The construction is such that when the casing is assembled over thedrum the locking projection 96 of the locking lever 90 engages the peripheral teeth 29 of the gear 28 secured to the front wall 18 of the drum.

When the drum is rotated in one direction in a manner to be hereinafter described to bring the desired compartment in registry with the door aperture of the casing, the projection 96 is permitted to ride over the peripheral teeth of the gear wheel by reason of the yielding nature of the coil sprin 93 secured to the outer end of the drum locking lever. A notch or recess 98 is provided near one end of the drum locking lever to permit the yielding engagement of the locking projection with the gear wheel only when the door is in closed position.

The door is normally maintained in closed position by means of a coil spring 99 engaging at one end an inwardly extending projection or lug 100 on the main door operating lever 52 said spring being secured at its other end to a lug or projection 101 on one arm of a rocking lever 102 pivoted at 103 to the inner face of the casing. The door lever and door are normally securely locked in closed position against movement by means of a locking lever 104 pivoted at 105 to the main door operating lever said lever 101 having its free end normally held by means of a spring 106 in contact with or adjacent to a lug or projection 107 preferably integrally formed on the inner face of the casing. The lower end of the tension spring 106 is secured to a projection 108 also formed on the inner face of the casing. The free end of the pivoted lever 104.- is further provided with a plurality of notches or recesses 109 designed for engagement with the projection107 on the casing. An inturned lug or projection 110 on the main door operating lever 52 serves as a stop to limit the inward movement of the pivoted lever 104 under the tension of the coil spring 106.

\Vhen the door is moved to open position upon the actuation of the machine, means are provided to lock said door in open position against the tension of the coil spring 99 the tendency of which is to close the door. These means comprise a rounded shoulder or notch 111 on the end of one of the arms 102' of the rocking lever 102 which shoulder drops down and engages a cooperating lug or projection 112 on the main door operating lever 52 when the door is moved to open position. The arm 102 of the rocking lever 102 is further provided with an inwardly extending lug or projection 113 the engagement of which causes the door to be automatically returned to closed position in a manner to be described.

The coin controlled mechanism within the h ousiug 69 includes a double faced rotary cam The loosely mounted tubular sleeve is dis-' posed immediately adjacent the disk member 115 and is provided on one end with a pair of diametrically opposed peripheral notches or recesses 121 adapted to be engaged by one end of a locking pawl 122 pivoted at 123 to the disk member, the other end of said pawl being yieldingly maintained in contact with the periphery of said tubular sleeve by means of a coil spring 124 secured to said pawl and secured at its other end to a projection 125 which may be integrally formed with the loosely mounted disk member 115. The other end of the loosely mounted tubular sleeve member 118 is provided with a cut-away portion 126 extending for substantially one half of the circumference of said member and forming a projecting shoulder 127 adapted to be engaged by the spring pressed pawl 34 pivotally mounted on the gear wheel 28 secured to the drum.

Vhen the machine is to be actuated, and assuming the door to be closed, the operator first visually selects through the windows 63, the article which he desires and then rotates the operating handle to the left or in a counter-clockwise direction as viewed in Fig. 1. In this direction the shoulder 127 on the tubular sleeve 118 engages the free end of the pawl 34 carried by the drum, and freely rotates the latter on its journal support 11 until the desired compartment is aligned with the door aperture, at this time obstructed by the closed door 48. During this reverse rotation in a counter-clockwise direction of the drum to select the article to be purchased, the projection 96 of drum locking lever 90 is permitted to ride over the peripheral teeth of the gear wheel carried by the drum by reason of the yielding nature of the spring 93. The notch 98 in the drum locking lever permits the latter to be intermittently elevated by the outward pressure of the gear wheel teeth, said notch being adapted to receive therein the projection 100 of the door operating lever 52, which projection in the absence of said notch would prevent the lever 90 from being elevated and consequently prevent the drum from being rotated to select the compartment desired. The proper coin is inserted in the slot 7 4: of the coin control housing and the operating handle secured to the main central shaft 71 is now turned to the right or in clockwise direction as viewed in Fig. 1. Failure to insert a coin results in the inabilit to rotate the operatinghandle 72 and sha t 71 by reason of the engagement of the locking pawl 122 carried by the disk member 115 with one of the peripheral recesses 121 of the tubularmember 118 looselyicarried by said shaft, it being understood that the tubular member one of the peripheral notches 121 carried by 'the tubular member after the latter is engaged and rotated by the transverse rod mem her 120. The insertion of the coin permits the disk member 115 to be thereafter rotated until the lowermost roller 117 carried by said disk engages the curved cam surface 128 of the door locking lever 104 pivoted to the main door operating lever 52. 'As the roller 117 moves upwardly against the said cam surface, the locking lever 104.- is moved outwardly against-the tension of the spring 106' and out of engagement with the locking projection 107 on the casing. Immediately thereafter the said roller 117 engages a corresponding curved cam surface 129 on the main door operating lever 52 thereby resulting in said lever and the door carried thereby being moved to open position against the tension of coil spring 99. This opening movement is continued by the rotation of the roller 117 until the depending extension 50 of the door frame engages an integral projection 130 on the casing, and the continued movement of the door lever results in the door and its extension frame 50 being swung quickly to open position on the auxiliary pivot 51. At precisely this moment the rounded shoulder 111 of rocking lever 102 engages the projection 112 ,on the door operating lever 52 thereby locking the door in open position. The purchaser may now obtain access through the open door to the contents of the compartment of the drum which he has moved into registrywith the door aperture. In this position of the machine and with the door open it will be observed that the projection 100 of the door operating lever 52 is disposed above and immediately adjacent the upper edge of the drum locking lever 90. This arrangement, due to the movement of projection 100 relative to the recess 98 in the drum locking lever, prevents the latter from being elevated to move a succeeding pocket into registry with :the door opening, and the drum is therefore securely locked by the locking projection 96 against movement in either direction. This is true while the door is open and also while the door is being moved to open and to closed position. It is only when the door-is closed and locked by lever 104 in closed position, that the drum 13 may be rotated, and this is due to the relation between projection 100 on the door operating lever and recess 98 in drum locking lever 90. These elements are only in alignment to permit yielding upward movement of the drum locking lever when the door is in closed position.

scrupulous persons.

l/Vhen the purchaser or a succeeding purchaser desires to again operate. the machine it is first necessary to close the door, thereby permitting the drum to be again rotated to select the contents of its desired compartment. The operation of closing the door is effected by a reverse movement of the operating handle in the same manner in which the drum is freely rotated when the door is closed. The door being open, there is no movement of the drum for the reasons described, and the adjacent end of the transverse rod 120 engages the projecting lug 113 of rocking lever 102 as the handle is turned in a reverse direction. Continued movement of the handle through the engagement described lifts rocking lever 102 until the rounded portion of its shoulder 111 is brought adjacent the upper portion of the locking projection 112 on the door operating lever 52. Thereafter the door is swung suddenly to closed position by the tension of the coil spring 9 which releases the rounded shoulder 111 from the projection 112 on the door lever. It will be observed in this connection that as main door operating lev-eris moved toward closed position, the lower end of door carrying member or extension 50 strikes a'second projection 131 integrally formed on the inner face of the casing, which serves to swing the door frame 49 and door sharply to closed position on auxiliary pivot 51, relative to the main door operating lever. In this manner a relatively small movement of the main operating, lever is caused to produce a greater range of movement of the door frame and door. This movement also permits the door locking lever 104 to be again swung by spring 106 into alignment with the projection 107 on the casing, to prevent the door from being again opened except only when the main operating shaft is turned in a clockwise direction to engage the other roller 116 of the loosely mounted disk member 115 with the curved cam surface of locking lever 104 and main door operating lever 52. As this operation can only be obtained upon the insertion of the proper coin, the machine is effectively locked against pilfering by unauthorized or un- WVhen the main shaft is being rotated in a clockwise direction to open the door, the pawl 34 carried by the gear wheel 28 slips loosely by the shoulder 127 of the tubular sleeve 118 as will be understood, thereby resulting in no movement of the drum when the operating shaft is being turned to open the door. The engagement described of the pawl 34 with the drum only take place when the door is closed and when the shaft is being rotated in a reverse direction. There cannot be any rotation of the shaft in a clockwise or forward direction when the door is closed except by the insertion of the proper coin, and this coin can not be inserted in this slot when the door is open because of the slidment of the shaft while the drum is locked stationary, to again swing the door to closed position. The manner of operating the machine by succeeding purchasers is exactly the same manner as has been described above for both opening and closing the door, the opening of the latter being permitted only by the insertion of a coin in the control housing slot 74.

Referring to Fig. 10 means are provided to protect the machine against damage in the event that the machine becomes temporarily out of order or in the event that unscrupulous persons attempt to operate the machine without first inserting the required coin in the coin control housing. The operating handle 72 is frictionally secured by suitable clutch mechanism to the transverse central shaft 71. Diametrically opposed resilient clutch members are carried by the handle and cooperate with the shaft 71 to permit the latter to be operated ,by the handle 72 after the desired coin has been inserted in the machine. As illustrated the handle 72 is provided with opposed boss portions 185 which are centrall apertured as at 136. The shaft is providec with opposed recesses or depressions adapted to coincide with the apertures 136. A pin or plunger 137 is loosely seated within each aperture 136 and is normally pressed into engagement with the opposed recesses of the shaft 71 by means of a coil spring 138. The opposite end of each coil spring 138 bears against a set screw 139 which is threaded into the aperture 136. A lock nut 140 is provided and threaded into each aperture 136 to bear against the outer end of the set screw 139. It will be apparent that any desired tension of the springs 138 may be obtained by removing the lock nuts 140 and adjusting the set screws 139. The adjusted ten sion is such that the plunger 137 bears with sufficient force against the shaft 71 to permit the latter and the handle 72 to be turned as a unit during normal operation of the machine. Should the machine become damaged or should an attempt be made to operate the same without first inserting the required coin, the plungers 137 will be forced out of their engagement with the shaft 71 against the tension of the springs 138 and the handle 72 will be rotated independently of and without corresponding movement of the shaft 71. In this manner all of the mechanism of the machine controlled by the shaft 71, is protected against undue damage or breakage during the operation of the machine.

As best seen in Fig. 4 means are provided to insure the proper positioning of the disk member 115 with the rollers 116, 117 in substantial vertical alignment on each actuation of the machine. A lever 141 is pivoted at 142 to the casing and is provided at its free end with a roller 143. A tension spring 144 is secured at one end to the lever 141 and is secured at its other end as at 145 to the casing. The spring 145 maintains the roller 143 in engagement with the cam surface 146 of the double face rotary cam member 114 loosely mounted on the shaft 71.
