  • FIG. 28 ROYAL L. BARROWS BY OLIVER-A.LANDRY 6m x m ATTOR N EYS Sept. 13, 1966 H DQWD ETAL 3,272,508
  • This invention relates to an automatic bowling pinsetting machine. More particularly it relates to an automatic pinsetting machine intended for use with free standing bowling pins, a conventional bowling alley; a machine which has a suificient degree of flexibility and adaptability in its mode of operation to be useful in connection with the European bowling game known as Kegeln (more familiarly known in the United States as German Nine Pins).
  • bowling games have developed trom a common ancestry into two broad groups.
  • One group as illustrated by bocce or bowls involves rolling a weighted ball across a prepared surface toward a target.
  • the object of such games is to make the ball stop as near to the target as possible.
  • Such games are played out of doors on greens or courts.
  • the target is an arrangement of upstanding clubs or pins
  • the object of the game is to cause a weighted ball to knock over as many of the pins as possible.
  • Such games are for the most part played indoors on lanes or alleys. While there is a variety of games in this second group there have developed over the years rather stringent rules and regulations with respect to each such game governing, among other things, the size, shape and weight of the pins, the arrangement of the pins in the target, the size and weight of the ball and the manner in which the game is played and the score tallied.
  • pinsetting machines should be compact enough to fit in the space available in a 3,272,508 Patented Sept. 13, 1966 standard alley; should operate quickly and efficiently with a minimum of supervision and maintenance; should handle and reset the pins and balls in strict accordance with the rules of the particular game; and should not interfere with the normal interaction between the ball and the pins during the playing of the game.
  • Bowling pins normally have an irregular shape and as a result are diflicult to handle.
  • the early pinsetting machines were of the tethered pin variety wherein the top of each pin was connected by a string to an apparatus arranged directly above the target area. With such a machine the pins are reset merely by pulling on the strings thereby restoring the pin to its upstanding position.
  • Such machines have never really been satisfactory since the string interferes with the free movement of the pin thus interfering with the normal interaction between the balls and the pins and, on occasion, the several strings become entangled and intertwined, thereby interfering with the pin resetting cycle.
  • pinsetting machines have been developed and introduced commercially for automatically resetting free standing (as contrasted to tethered) pins in connection with the standard United States bowling games, such as ten pins, candle pins, duck pins and rubber duck pins. Such machines duplicate with remarkable precision the desired activities of a pin boy which they replaced.
  • these machines are provided with sweep means for removing the pins from the alley and depositing these pins in the pit normally provided at the rear of the alley; means for separating the pins from the balls; means for elevating the balls and depositing them in the ball-return track normally provided; means for lifting the pins to a position above the end of the alley; means for orienting the pins and distributing them to a reciprocal pinsetting mechanism; means including the reciprocating pinsetting mechanism for placing the pins in the exact desired position on the alley; means including the reciprocating pinsetting mechanism for lifting the still standing pins after a ball has been bowled to permit the fallen pins (the deadwood) to be swept into the pit when the rules so require, and control means for causing the machine to operate upon detecting the passage of a ball or upon command of the bowler.
  • German nine pin bowling according to the regulations established by the German Bowling Association (Deutscher Kegler Bund) the target is of a diamond shape with eight common pins arranged in the form of a square having two opposing corners paralled with the longitudinal axis of the alley on the center line thereof.
  • a common pin is located on each of the corners of the square and at the mid-point of each side.
  • a king pin is located at the center of the square.
  • the layer of pins in the target is symmetrical and the pins as viewed by the bowler are arranged in five equally spaced parallel rows with three pins including the king pin arranged along the center line of the alley, a row of two pins on each side of the center row, and a row consisting of one pin each on the outside at each side.
  • the pins are turned from hard wood with the common pin having a height above the base of 40 cm., a maximum diameter of 10 cm. with a generally barrel-shaped lower section and a necked in upper section. More specifically the diameter of the pin at the base is 6.5 cm. and the thickness of the pin increases on a smooth curve above the base until at a point cm. above the base the diameter is cm. The 10 cm. diameter continues to a point 16 cm. above the base at which point the pin is necked in to a minimum diameter of 5 cm. at a point 26.5 cm. above the base. Above this point the pin widens out again terminating in a semi-hemispherical cap having a diameter 8.6 cm. with the top of the pin located as stated above at a point 40 cm.
  • the king pin is identical with the common pin except that its semihemispherical cap is further provided with an upstanding arm having a minimum diameter of 3 cm. and a height of 40 cm. above the base, a maximum diameter of 4.5 cm. at 41.5 cm. and a flat top at 43 cm. above the base.
  • Pins of both varieties are provided with a ball having a diameter of 17.5 mm. which protrudes from the bottom of the base at the center line of the pin for a distance of 6 mm. This ball fits into a corresponding socket provided in the alley floor at the exact position prescribed for the desired array. This ball which protrudes from the base serves two functions to ensure that the pin is exactly located in the array and to prevent the pin from sliding out of position. The distance that the inset ball protrudes is such that the pin is substantially out of balance unless that ball is located in a corresponding socket.
  • the ordinary bowling ball used for German nine pin bowling has a substantially larger diameter than the maximum diameter of the pin being about 19 cm. in diameter as compared to 10 cm. For comparison it is somewhat larger than the small balls used for such United States games as candle pins, but are substantially smaller than a full size ten pin ball.
  • any combination of any numbers of the nine pins may be selected.
  • the preselected combination of pins are reset after each roll of the ball until such time as a new selection is desired.
  • any combination of any number of the nine pins may be selected.
  • the ball may be rolled as often as desired and the fallen pins (the deadwood) are removed after each roll of the ball.
  • the pins are reset at the bowlers request, and upon being reset the bowler may again select any combination of pins.
  • Abraemenin this game a full array of nine pins are used and the ball is rolled as often as necessary to fell all of the pins. The deadwood is removed after each roll of the ball and the entire array is replaced after the last pin is felled.
  • Autom-spick-this game is the same as Abraemen except that the full array is replaced not only when the last pin is felled but also when all of the pins other than the king pin have been felled.

  • the overall machine is shown schematically in FIG. 1 in which the bowling alley is indicated at A, the conventional pit area at the rear of the alley at B, and the wall conventionally located at the edge of the alley alongside the pit and target area at C.
  • the machine generally consists of a sweep mechanism D, a rotating pin and ball separator or turntable E, a ball elevator F, a pin elevator G, a king pin conveyor H, a common pin conveyor I, a common pin distributor J, a pin storage rack K, a reciprocating pinsetting mechanism L, and a sweep and pinsetting mechanism drive means M.
  • the switches and relays for controlling the apparatus are contained in the box indicated at N.
  • the pins are indicated at Fe for common pins and at Pk for king pins.
  • the turntable E and the elevators F and G are designed to fit into a conventional pit B and the remainder of the pinsetting mechanism is designed to rest on the top of the pair of conventional pit walls C.
  • Sweep mechanism D and the pinsetting mechanism L operate together in the manner described in detail in Dowd and Barrows Patent No. 3,063,716, issued November 13, 1962.
  • This portion of the mechanism is actuated by the passage of a ball down the alley by means of a ball detecting switch (not shown).
  • This switch preferably comprises a photoelectric cell and a corresponding light source arranged on opposite sides of the alley at a height whereby the light beam is broken by the passage of a ball and about one and one-half feet in front of the front pin.
  • the ball detector switch may comprise an inertia switch mounted on the padded bumper which is normally pivotally mounted above pit B beyond the end of alley A for the purpose of deflecting flying balls and pins into the pit. In this latter instance the switch is actuated by the sudden movement of the padded bumper.
  • Sweep D and pinsetting mechanism L have two alternate sequences or cycles, a setting cycle and a deadwood cycle.
  • the setting cycle the sweep D moves downwardly and rearwardly as soon as its drive mechanism is actuated by the ball detector switch, to the level of the alley and then moves along the level of the alley to the pit pushing any pins that may be located, whether fallen or standing, in the target area into the pit.
  • sweep D reaches the pit it reverses its direction and returns to a position still next to the alley just in front of the pinsetting mechanism where it stops and acts as a ball guard to prevent the pinsetting mechanism L, the pie, from being damaged if a ball is rolled While pie L is depressed.
  • common control means M is so arranged that sweep D and pie L can be driven through either the resetting cycle or the deadwood cycle interchangeably in any sequence, the selection of the cycle being possible until the actual start of the cycle. Since none of the regular German games is played with deadwood ( fallen pins) on the alley one cycle or the other is initiated every time the ball detector switch is actuated. In addition to other controls the bowlers position is provided with a pin setting switch which switch will initiate the setting cycle at the bowl-ers command.
  • the floor of the pit B is provided with a constantly rotating turntable E which, in connection with bafiies overlying turntable E, separate the pins from the balls and direct the pins to pin elevator G and the balls to ball elevator F.
  • Both turntable E and ball elevator F move continuously and ball elevator F lifts the balls from the floor of the pit B and dumps them one by one into the conventional ball return track (not shown) for return by gravity to the bowlers position.
  • Pins Fe and Pk are lifted one by one by pin elevator G past a king pin separator which deflects the king pins Pk from the elevator. Upon being separated from the elevator pins Pk fall through a pin orienter onto king pin conveyor II. Common pins Pc pass through the king pin separator to the top of pin elevator G where they are deflected from elevator G through a pin orienter onto common pin conveyor I. In both instances the pin orienter causes the pin to fall base first onto the pin conveyor so that the pin travels along the conveyor base first.
  • King pin conveyor H carries successive king pins Pk directly to the king pin position in the pin storage rack K.
  • King pin conveyor H is provided with a feed section and a delivery section and appropriate drive means are provided to feed successive king pins Pk one by one into the storage rack K when such a pin is needed, and to stop the conveyors and especially the delivery portion when the king pin position in rack K contains a king pin or when the king pin is not required in the particular game.
  • the feed section of conveyor H is driven from pin elevator G and the delivery section from sweep mechanism D.
  • Common pin conveyor I delivers common pins Pc one by one to rotary common pin distributor I where the pins are deposited upright in separate common pin receiving pockets.
  • the drive of the pin distributor I is so arranged that the pin distributor advances one pocket each time a pin is fed into a pocket or when the pocket coming under the end of conveyor I already contains a pin.
  • Conveyor I is driven by elevator G and switches activated by distributor I are provided to stop both elevator G and conveyor I when additional pins are not required by distributor I.
  • Pins P are transferred by gravity from distributor I into storage rack K and from storage rack K onto pinsetting mechanism L. Alternate means are provided whereby pins may be released from distributor I into rack K one by one or as a unit depending on whether the selective bowling game has been selected or not. Interlock means are provided to prevent the pins from being released from distributor J into storage rack K until storage rack K is empty ready to receive the pins. Other interlock means are provided to prevent the discharge of pins P from storage rack K onto pinsetting mechanism L until pinsetting mechanism L is in its pin receiving position, is empty of pins, and the sweep and pinsetting control means M calls for the next cycle to be a pinsetting cycle.
  • the bowling pinsetting machine of the present: invention obtains an extreme degree of flexibility of operation primarily by simplifying the component parts.
  • each portion of the machine is designed to perform a single function and to perform that function with a high degree of precision and dependability.
  • Each portion carries out its own function automatically and independently of any other portion of the machine controlled primarily by the presence or absence of a pin or ball in a certain control position at a certain time.
  • the machine has the inherent capability of an almost unlimited number of sequences of operation. Five are normally provided to correspond to the five standard games as established by the German Bowling Association.
  • Turntable E As shown in FIG. 2 the floor of pit B is replaced by a turntable 41.
  • Turntable 41 is circular in shape, oriented generally horizontally, but with an outward downward slope toward the edges from a crown at the center and is mounted at its center on a vertical shaft.
  • a circular friction surface, such as a piece of carpeting, indicated at 42 is mounted on the surface of turntable 41 preferably off center as shown.
  • the diameter of turntable 41 is as large as may be conveniently located in the standard pit B and is surrounded by a stationary masking structure 43 which extends to the wall 44 of pit B.
  • Masking structure 43 in each portion slopes from wall 44 towards turntable 41 sufliciently that pins or balls falling onto mask 43 will tend to roll towards turntable 41.
  • Ramps 45 and 46 are provided at the corners of pin B adjacent alley A with a sharper slope toward turntable 41, than the slope of mask 43 to prevent pins from jamming into these corners.
  • a similar ramp 47 is provided along the side wall 44 adjacent pin elevator G for the same purpose. Pin elevator G is mounted in one rear corner of pit B and wall elevator F in the other.
  • Turntable 41 is rotated continuously by a drive which consists of motor 48, drive belt 49, pulleys 51 and 52 mounted on a vertical shaft 53, second drive belt 54, pulley 55, mounted on vertical shaft 56 which in turn through a pulley (not shown) drives belt 57 which drives pulley 58 mounted on the mounting shaft for turntable 41.
  • the drive for ball elevator F is taken from a second pulley 59 mounted on the top end of shaft 56 by means of belt 61 which passes around pulleys 62 and 63 and passes around a pulley mounted at the top end of ball elevator F. It will be noted that the several pulley combinations all serve as speed reducers in order to keep the rotation of turntable 41 and the greater advance of ball elevator F at a reasonably low rate.
  • motor 48 in normal operation is powered continuously while the machine is in operation.
  • a separate cut-off switch is provided if, for any reason it is desired to stop turntable 41 or elevator F.
  • Both pin elevator G and ball elevator F comprise a parallel pair of chain belts which run vertically over two pairs of horizontally separated sprockets, one such pair being located below the level of turntable 41 in each case, the other at the top of the respective elevator.
  • the parallel chains are connected at intervals by horizontal rods.
  • the chain belts and rods of ball elevator F are indicated at 64 and 65 respectively, and of the pin elevator G at 66 and 67 respectively.
  • the lateral distance between chains 64 of ball elevator F is slightly greater than the diameter of the ball, and the lateral distance between chains 6 of elevator G is slightly greater than the over-all height of the king pins. Both elevators are run so that the cross rods 65 and 67 move upward in the front and downward in the rear.
  • the front and rear are separated by vertical walls indicated at 68 in the case of ball elevator F, and indicated at 69 in the case of pin elevator G, located sufficiently behind the plane of upward movement of cross bar 65 in the case of ball elevator F, and cross bar 67 in the case of pin elevator G, that the center of gravity of a ball or of a pin as the case may be is just slightly behind the respective cross bar toward the aforesaid vertical wall.
  • Tapered internal vertical guides 71 and 72 are further provided for ball elevator F at the sides between the plane of cross rods 65 and rear wall 68 to steady the ball in its upward movement on the elevator.
  • Exterior guides '73 and 74 for elevator F, and 75 and 76 for elevator G are provided outside of both sides of the upward side of both elevators with slots to receive the conveyor chains, and to maintain the respective chains at a fixed clearance from the rear Wall.
  • a transverse bafile 78 is provided across turntable 41 above and behind the center thereof.
  • the clearance between turntable 41 and the bottom of baffle 78 is at all places sufficient to clear a pin lying on its side on the turntable.
  • the clearance is insufficient to clear a ball except on the left hand side (turntable 41 as shown rotates clockwise) so that a ball once it passes into the rear section is trapped and cannot pass out.
  • a supplemental baffle 79 is provided in front of the entrance to the pin elevator G, and has an insufiioient clearance to pass a ball.
  • a second supplementary bathe 81 is provided on the rear of baffle 78 near the center of the right side to deflect ball 77 towards the entrance 82 to ball elevator F.
  • Entrance 82 to ball elevator F comprises two elements located slightly above the plane of turntable 41 separated by a distance slightly greater than the diameter of ball '77.
  • Inner element 83 extends out over turntable 41 and acts to deflect pins away from the entrance.
  • Outer element 84 extends to a point adjacent the periphery of turntable 41 at the rear of bafile 78.
  • the floor of entrance 82 slopes toward elevator P so that once a ball 77 passes into the entrance it will roll into elevator F.
  • the pins P0 and Pk landing at pit B land on a roll to turntable 41 where they are carried around and around beneath the bafi le. Because of the tilt of turntable 41 the pins tend to roll toward the edge.
  • the inner portion 83 of ball entrance S2 acts as a pin selector pushing the pins toward the center of the turntable 41 thereby re-orienting the pins continuously.
  • the pins go around and around and are re-oriented they eventually, one by one, orient themselves so that the leading end (top or bottom) of successive pins lies at the periphery of turntable 41 along a tangent thereto in a position to enter entrance 185 of pin feed 86.
  • Pin feed 86 which is separated from turntable 41 by wall 87 has a floor that slopes toward pin elevator G and is generally parallel to the cross bars thereof.
  • the floor of pin feed 86 lies a. substantial distance below the level of turntable 41.
  • the width is substantially the same as the Width of the cross bar.
  • next cross bar 67 comes up beneath the pin next adjacent the elevator and tends to pick up this pin. If the center of the gravity of the pin is between the plane of bar 67 and wall 69 the pin will stay on the elevator and will reorient itself (if necessary) so that its axis is parallel laterally to both the plane of bars 67 and of wall 69. If it so happens that the particular pin is sufficiently cocked that its center of gravity is outside of the plane of cross bar 67 that pin will fall off the elevator and back into pin feed 86.
  • Chain guides 75 and 76 are mounted on the face of side walls 91 and 92 of elevator G respectively, and rear wall 69 is mounted between two side walls between the upward and downward flights of conveyor chains 66, 66.
  • Chain 66, 66 pass between a pair of sprockets mounted on roller 93 rotatably mounted at the base of conveyor G between side walls 91 and 92 and a pair of sprockets mounted on drive shaft 94 which in turn is rotatably mounted between the side walls 91 and 92 at the top of the conveyor.
  • a pair of adjustable sprockets 95 and fixed sprockets 96 are provided at the top rear of elevator G to adjust tension of chains 66.
  • Elevator G is driven by motor 97 which is connected by drive chain 98 to reduction gear 99 which in turn is connected by drive chain 101 to drive sprocket 102 mounted on drive shaft 94.
  • An idle sprocket 103 is provided to adjust the tension of drive chain 101.
  • Motor 97 and reduction gear 99 are mounted on bracket 104 which is mounted to the outside of side wall 92 near its upper end.
  • Means are provided associated with pin elevator G for detecting and removing the king pins Pk from the elevator, for orienting the king pins and delivering the oriented pins to king pin conveyor H. Means are also provided for removing the common pins Pc from elevator G for orienting the common pins and delivering the oriented pins to common pins conveyor I. Since the king pins are transferred to pin storage rack K, and the common pins are transferred first to common pin distributor J, from which they are released and fall into storage rack K, the king pin separating and orienting means are at an appropriate lower level relative to pin elevator G than the common pin separating and orienting means.
  • Elevator G and associated means are so arranged that when this happens the pin falls through the pin orienting means indicated generally at 106 onto tapered sloping pin slide 107 and down slide 107 to the common pin conveyor 1.
  • Pin orienting means 106 and pin slide 107 are both mounted on brackets indicated generally 103 mounted on the side walls 91 and 92 of elevator G in a position forward of the moving portion of elevator G.
  • Pin orientor 106 It will be recognized that pin feed 86 merely acts to line the pins P up along an axis generally parallel to the cross rods 67 of elevator G, and that no means are provided to control the orientation of the pins on the elevator. Thus the pins lie on the elevator in random orientation, some with their head toward the right, some with their base toward the right. It is necessary however that all of the common pins Pc be fed to common pin distributor I in a base down condition. This means that the pins Pc must lie on conveyor I in a base forward position. A means indicated generally at 106 for orienting the randomly oriented pins is provided between the point where the pins are discharged from elevator G and slide 107.
  • pin orienting means 106 includes a transverse bracket 109 which is fastened horizontally between side walls 91 and 92 in pin elevator G, and passes across the front of elevator G with sufiicient clearance therefrom to permit pins to pass up the elevator freely.
  • Two deflector pin pieces 111 and 112 each comprising an upwardly extending pin portion 113 and 114 and a base portion 115 and 116 respectively are pivotally mounted on the outer surface of bracket 109 and 117 and 118 respectively.
  • Pin portions 113 and 114 extend well above the top of bracket 109 and, as shown in FIG. 7, are bent out at a substantial angle in a direction away from the conveyor.
  • Pin pieces 111 and 112 are connected by a connecting rod 119 pivotally mounted at one end to base portion 115 as indicated at 121, and at the other end as indicated at 122 to base portion 116, thereby causing the two deflected pin pieces 111 and 112 to reciprocate in unison.
  • the length of connecting rod 119 is adjustable by means indicated at 123 and 124 and is so adjusted that when one deflector pin is vertically oriented the other is oriented outwardly.
  • Pin pieces 111 and 112 are located on bracket 109 in such manner that when oriented vertically pin portions 113 or 114 will be in line with the neck portion of the bowling pin at a point slightly below the knob of the top of the bowling pin, and the length of connecting rod 119 is adjusted such that when one of the pin portions 113 or 114 is oriented vertically the other pin portion 113 or 114 will clear the base of the pin.
  • Bracket 109 is so located on conveyor G that if pins are discharged from the conveyor they will fall past and through the upwardly extending pin portion in such manner that either pin portion 113 or 114 will contact the bowling pin.
  • a stop 125 and 126 respectively is provided at the lower outer corner of base portions 115 and 116.

  • the left and right deflector pin pieces 111 and 112 operate in unison and reciprocate as a unit over a limited path of travel between a position where one or the other is in the path of the upper end of a bowling pin, and where the one which is not in such a position is so located as to permit the base of the bowling pin to pass without interference.
  • Actuating means 127 includes a bracket 128 mounted on and depending from bracket 109, and a cross rod 129 mounted transversely on the bottom of bracket 128 and extending below and parallel to bracket 109.

  • the geometry of the pins is such that when one of wheels 148 or 149, coincides with the path of travel of the thinnest portion of the neck of the pin the other of wheels 148 or 149 will coincide with a portion of the body of the pin.
  • pin orienting mechanism 106 are so related to conveyor G and to each other that when the body portion of a pin passing upward on the elevator contacts one of wheels 148 or 149 it will raise that wheel a suflicient distance along its path of travel to cause the corresponding deflector pin piece 111 or 112 to swing to its outermost position, and the other of pin pieces 111 or 112 to assume its vertical position with stop 125 or 126 as the case may be in contact with bracket 109.
  • Slide 107 is bent at such an angle that the pins will slide down the slide readily. It is provided with upstanding side walls 153 and 154 of sufficient height to prevent the pins from jumping out.
  • the upper end of the slide 107 is in such position as to receive the pin as it falls out of the pin elevator, and the lower end is in such position :as to dump the pin directly onto pin conveyor I.
  • the upper or receiving portion of slide 107 is wide enough to receive a pin oriented horizontally. The width of the slide decreases towards its lower end so that the bottom or exit portion is narrow enough that it will not pass a pin unless the pin is generally oriented in an up and down direction relative to the slide.
  • pin orientor 106 causes the pins to enter slide 107 with their base first so that it is the base of the pin that comes into contact with conveyor I first, and the pin therefore is necessarily carried up conveyor I with its base forward. Since, as will be explained later, a common drive is provided for elevator G and conveyor I no more than one pin at a time can be delivered to conveyor I. The pins, therefore, proceed up conveyor I in a single file base first.
  • the primary advantages of elevator G and pin orientor 106 lie in the fact that both are simple, direct and foolproof. There is no possibility that they can jam, that the parts can become bent, or the like.
  • the elevator accepts pins one at a time but only if the pin is oriented parallel to cross rods 67. If a second pin tries to rise in a single position, or if the pin is not properly oriented, the second pin or the improperly oriented pin, falls out of the elevator. As the pin rides up elevator G past Wheels 148 or 149 of pin orientor 106 the pin either clears these Wheels or it doesnt.
  • Pin orienting mechanism 155 and slide 156 is provided at an appropriate lower level of elevator G for the purpose of orienting king pins Plc and delivering such king pins base first to king pin conveyor H.
  • Pin orienting mechanism 155 and slide 156 are supported by bracket 157 which is mounted on the side walls 91 and 92 of elevator G.
  • King pin detector and deflector 158 As mentioned above, :means are provided for detecting and removing king pins Pk from elevator G. These means which are indicated generally at 158 and consist of a pair of elements 159 and 160 inset into guides 75 and 76 of elevator G between rear wall 69 and the paths of conveyor drive chains 66 are shown in detail in FIGS. 8, 9 and 10.
  • Each element 159 and 160 consists of a king pin detector plate 162 and a king pin deflector plate 163 mounted in a common housing 164.
  • Housing 164 is generally U- shaped with a rear wall portion 165, a side wall portion 166, and a front wall portion 167.
  • Rear wall portion 165 is adapted to be mounted in rear wall 69, front wall portion 167 extends inwardly for a sutficient distance as to serve as a continuation of guide 75 or 76 as the case may be.
  • King pin detector plate 162 is pivotally mounted at its bottom end on support shaft 168 which in turn is mounted between front wall 167 and rear Wall 165 near the lower end of element 158 or 159 in such manner that the free end of plate 162 is free to move toward and away from side wall 166.
  • King pin deflector plate 163 is similarly mounted on support shaft 169 which is mounted between front wall 167 and rear wall 165 of element 158 or 159 near its upper end.
  • Detector plate 162 is connected to deflector plate 163 by a linkage which includes bracket 171 mounted on the rear of plate 162, a shaft 172 pivotally mounted on bracket 173 which in turn is mounted on the inner side of side wall 166, bracket 174 mounted on the rear of plate 163, swinging link 175 which joins bracket 171 with one end of shaft 172 and swinging link 176 which joins the other end of shaft 172 with bracket 174.
  • a compression spring 177 of substantial strength mounted between the rear of plate 162 and the inner portion of side wall 166 tends to normally urge plate 162 away from side wall 166.
  • the action of the linkage is such that if plate 162 is pushed toward side wall 166, plate 163 is forced outwardly from side wall 166.
  • bracket 173 By locating bracket 173 in an appropriate position relative to the ends of shaft 172 the magnitude of the relative motion of the two plates can be suitably regulated. For example, as shown, bracket 173 is closer to the bottom end of shaft 172 than it is to the upper end, thus magnifying the response of plate 162 to any motion of plate 163.
  • the free end of the king pin deflector plate 163 is formed on a taper with the intersection between the free edge and the rear side in an acute angle.
  • An abutting portion 178 depending inwardly from the free edge is provided and acts as a contacting surface against the pins when deflector pin 163 is extended.
  • the free edge of detector plate 162 is also tapered, but with an acute angle at the intersection between the free edge of the front side so that there is no interference between the two plates and the king pin will remain in contact with the detector plate 162 until the pin has been removed from the conveyor.
  • a stop is provided conveniently by having bracket 174 contact shaft 172 so that in the normal position deflector plate 163 is oriented parallel to side wall 166.
  • Detector plate 162 is so shaped and the linkage is so arranged that its free end is parallel to, and in the same plane as deflector plate 163, when the deflector plate is in its normal position.
  • the lower portion of detector plate 162 (that portion adjacent pivot 168) slopes towards the side wall 13 166 with its lower or pivot edge within the limits of front wall 167.
  • the elements 159 and 160 of king pin separator 158 are dimensioned and located as follows:
  • the outer edge of front wall 167 is in the same vertical plane as the outer edge of front Wall 167 is in the same vertical plane as the outer edge of guides 75 and 76 and serves as a continuation thereof.
  • Guides 75 and 76 are separated by a distance substantially equal to the overall length of a king pin Pk.
  • the plane of deflector plate 163 and of the free end of detector plate 162 is parallel to the plane of the inner edges of guides 75 and 76, but the horizontal distance between these elements in the normal position is substantially equal to the overall length of a common pin Pc.
  • king pin separator 158 serves as a centering device for common pins Pc assuring that they will be in the proper position laterally for contact with pin orienting means 106.
  • king pin Pk will fall out of the elevator through king pin orienting means 155 onto king pin slide 156, and then in a base down orientation due to the action of king pin orienting mechanism 155 onto king pin conveyor H.
  • the relative positions of the various parts of king pin detector and separator 158 as the king pin Pk is passing through is shown in FIG. 8.
