An important object of the invention is to pro- Figure 141s a plan view of the same,

vide means to accurately set the pins upon the 8 5 an exploded perspective View of bed of the alley, raise the remaining standing the carrier and associatedelements, pins after the ball has been thrown. and then Figure 16 is a section taken on line accurately reset such pins in the, true, l6- lt, o.1ugure 8, I 55 I of the alley, Figures 1, 5 and 7, having the usual spots 2|. At the forward end of the bed 29 is the usual pit 22. The numeral 23 designates the usual partitions, one of which is provided with the ball return track or runway 24. The numeralv 25 designates the bowling pins.

The resetting apparatus for each alley comprises a pair of spacedvertical grooved tracks or guides 26, which are preferably U-shaped in cross-section. The upper ends of the vertical roller from the branch 3| into the branch 33.

tracks are rigidly connected with a horizontal frame or support 21. and their lower ends are rigidly attached to the partitions 23. I Each grooved track 26 is provided with a laterally extending portion 29, including an upperbranch 30 and a lower branch 3| connected by an intermediate curved portion 32. The upper and lower branches 30 and 3| are inclined vertically and diverge toward the vertical track 26. Each vertical grooved track 26 is also provided with a third laterally extending grooved branch 33, which leads into the grooved track 26 inwardly of and near the upper end of the branch 38 and leads into the portion 29 adjacent to the curved intermediate portion 32. The upper branch 30 also leads into the outer end of the branch 33, adjacent to the curved'portion 32, and a pivoted gate 35 is arranged to control the passage of the The gate 35 is pivoted at 36 adjacent'to its upper end. The gate 35 is forced inwardly by a spring 31. The gate has a stop shoulder 38 at its lower end. It is thus seen that a roller travelling downwardly through the branch 30 will depress the gate 35 and pass the same to enter the lower branch 3|, but when this roller travels upwardly through the branch 3|, it will engage the stop shoulder 38 and be deflected thereby into the branch 33. A gate 39 is pivoted at 48 and has astop shoulder 4| and is arranged adjacent to the union of the branch 33 and the track 26. This gate is springpressed and is similar to the gate 35 and will serve to permit the roller travelling upwardly through the branch 33 to enter the vertical track 26, but will prevent the roller entering the upper end of the branch 33 when it moves downwardly in the track 26. A second pivoted gate 42 is arrangedadjacent to the union of the upper end of the branch 30 with the track 26 and has a top shoulder 43. This gate jis spring-pressedand similar to the gate 35. This gate 42 will deflect the roller'from the grooved track 26 into the upper end of branch- 38- upon the downward movement of the roller. When the rollermoves upwardly in the track 26 beneath the gate 42,

it will depress the gate and move past it to the upper portion of the track 26. Arranged at the junction of the lower end of the branch 3| and the track 26 is a-two-way gate 44, pivoted at 44' and having a spring catch' 45' to, releasably hold the gate in the shifted position."

The apparatus embodies a carrier designated as a whole by the numeral 45.

This carrier com-.

prises an intermediate preferably rectangular frame 46, see particularly Figure 15, preferably formed of pipes. The frame 46 comprises sides 41 and ends 48, connected by tubular couplings The numeral 58 designates a triangular setting frame, preferably formed of pipes and including a base 5| and sides 52, which converge, as shown. The base 5| and sides 52 are connected by elbows 53, included in the couplings.

A tubular coupling 54 is connected in the base.

5| and has connection with a pipe 55, extending toward the converging ends of the sides 52 and connected with a tubular coupling. 56, also connected with the converging ends of the sides 52.

The tubular coupling 56 is formed integral with a tubular coupling 51 carried by. the end 48, as shown. The tubular coupling 54 is formed integral with a tubular coupling 58 carried by the other end 48, these couplings having communica- Arranged upon the opposite side of the frame 46 is a resetting triangular frame 59', preferably formed of pipes including a base 59, connected with converging sides 60 by tubular elbows 6|. The elbows 6| are preferably formed integral with the adjacent elbows 49 and communicate therewith. The sides 68 converge in one direction for connection with a tubular coupling 62, also connected with a pipe 63 extending to the base 59 and connected with a tubular coupling 64. The coupling 64 is formed integral with the coupling 51 and the coupling 56, and these tubular couplings are in communication with each other. The coupling 62 is formed integral with the coupling 58 and the coupling 54, and these tubular couplings are in communication with each other.

It is thus lar arrangement of the bowling pins, when placed in spotted position upon the bed of the bowling alley, except that the base of the group of suction devices before the carrier in inverted is posi- I tioned next tothe player, so that the number one suction device will be arranged next to the player when the carrier is inverted, ina manner to be described. Each suction device comprises a flexible suction cup 66, secured to a tubular nipple 61, in communication with the bore of the setting frame 50. The suction cup 66 is preferably formed of rubber and is of a suitable size to fit over the end portion of the head end of the'bowling pin 25. The nipple 61 has a passage 68 adapted to establish communication between the .bore of the frame 50 and the interior of the 'suctioncup, such communication being controlled by a spring actuated self closing valve 69, having a stem'lll, projecting into the suction cup 66,1-and adapted to be engaged and moved by thehead .end of the bowling pin, to unseat the valve element of the valve 69. It might be stated a at this point that before the head end of the bowling pin passes into the suction cup, that the valve 69 is closed, whereby the suction within thebore of the setting frame is not transmitted to the suction -cup, but as soon as the head end of the bowling pin enters the suction cup 66 sufli- -ciently so that the suction cup may have proper suction cup 88, which will have proper holding action'with the head end of the bowling pin. Each suction device is preferably provided with a wire guard or stabilizing device H, which is rigidly attached. to the setting frame adjacent to the 'sucetion device. This guard is tapered and increases in diameter outwardly and is preferably adapted to suitably engage with the intermediate or body portion of the bowling pin, to hold the same against any perceptible tilting action with respect to the suction cup, when the carrier is being inverted. The guard includes a ring 12 and resilient rods 13. The ring 12 is of a greater diameter than the head end of the pin but of a smaller-diameter thanthe largest diam;-

eter of the pin, and the ring will engage the pin inserted therein in an inverted position, at a .point above its center of gravity, whereby the pin will automatically assume a vertical position while its head end engages the suction cup.

The resetting frame. 58 carries resetting suction devices 14, also adapted to engage with the head end of the pins. These resetting devices arearranged in a spaced triangular group corresponding to the arrangement of the pins, when spotted for playing. The triangular groups of suction devices taper in opposite directions; and

the apex of one triangular group is at the base of the other triangular group, at a point equi distantly spaced from the opposite ends of the tubular nipple l8 and preferably has a coil spring 18 embedded therein, to impart to the shank a suitable'stiffness' against lateral movement. This spring 18 may also be arranged upon the interior of the shank 11', if desired. A valve device 18 is mounted in each tubular nipple and includes a spring pressed valve bodyyadapted to be opened by a stem 88, connected with the valve body and arranged within the suction cup I1; It might be stated at this point that before the suction cup is brought into engagement with or proximity to the head end of the pin, that the valve body of the valve device 18 is closed, therefore cutting off communication between the interior of the shell '15 and the interior of the suction cup. 11.- However, when the head'end of the pin'is moved into the suction cup ll, it engages and moves the stem 88, unseating the valve body, whereby suction is transmitted from the shell 15 to the suction cup I1. As before stated, the tubular nipples I8 are so arranged that they are also disposed in triangular groups of three over the' entire area of the shell 15. The suction cups 11 extend throughout substantially the entire area of the shell 18-, and the shell has a diameter considerably larger than the diameter of the head end of the pin. This is an important feature of the invention. If the pin is off-center with'respect to the spot on the bed of the bowling alley, when the shell II descends in resetting the pins, in a manner to be described, the shell 15 is concentric with respect to the corresponding spot, while the pin is eccentric with respect to the spot. However,

suction device iswconsiderably larger than the head end of the pin, it will properly engage-with the head end of the pin, if it is in the concentric or' eccentric position with respect to the spot. As the resetting suction device engages the head end of the pin, three suction cups will at 'all times engage therewith, and their valves will be unseated so that the three suction cups will have .holding engagement with the head end of the pin. This is true if the pin is concentric with its 10 spot or eccentric with relation thereto for only a slight distance, or for a considerable distance. In Figures 11 and 12 the suction cups II are shown as preferably separate and arranged in close relation, while the invention is not restricted 5 to this arrangement. In Figures 13 and 14, the suction cups ll are shown as connected at their lips with a web orsheet 8i and also at their stems 17' by webs 82. By having three suction cups always engaging the head end of the pin, the pin 20 will be suspended in a truly vertical position, when being moved from and toward the bed of the bowling alley, thus rendering it'possible to return the pin to the precise position on the bed that they occupied before being lifted therefrom, 5

regardless of whetherthe pin was concentric or eccentric with respect to the spot. The invention is not restricted to employing three cups H in a group, as any suitable number of cups may be used, when properly arranged in the group.

As more clearly shown in Figures 10 and 11, thesuction devices are of such shape and size that they receive the reduced extremity of the head ends of the pins. It is preferred that the suction cup be smaller than the maximum diam- 85 eter of the headend'of the pin, so that "it will only engage with the reduced extremity of the head end of the pin. Since. this reduced extremity iswell within the maximum diameter of the.

head end, it is protected to a considerable extent 4 against injury, such as dents and scars, due to the falling or movement of the pins when struck, with the result that such reduced extremity ordinarily retainsa smooth or unscarred surface,

thusassuring an air tight contact between the 45 reduced extremity and the suction device or cup. The carrier 45 is arranged between the-two tracks 28, as clearly shown in Figures .7 and 8.

The carrier is rigidly mounted upon horizontal rock shafts 84, Figures 8, 9, 15 and 18, which are 5 attached to the sides 4'! of' the frame 46. The rock shafts 84 extendinto couplings 85, and are clamped therein, as shown at 88. The rock shafts 84 are journalled in bearings 81, which are rigidly bolted to plates 88,. rigidly secured to vertically 5g movable carriages 88. These carriages travel upon the outer sides of the tracks 26 and have guide rollers 88. The carriages are raised by cables 8| extending upwardly to be passed about drums 82, rotated" by motors 88. or the like. go

against turning movement, and movable verti- 85 orally with the carriage 88. The disk 88 is provided upon its inner face 81 with a circularly curved elongatedgroove 88, concentric with the shaft-84, and extending throughout 180. v(Joacting with the stationary disk 88 is a companion disk 88, having a central opening through which the shaft 84 passes, and having a port I88 passing through itsinner face and in permanent com-- U munication with the groove 88. The port Hill has since the effective suction area of the resetting communication withthe hereof the frame 48. 15

' Rigidly connected with the outer ends of the rock shafts 84 are cranks IOI, carrying rollers Ij02 at their free ends, and these rollers are adapted to travel within the grooved tracks 26 and their several branches, in a manner to be described.

A suction pipe I03 is connected with each stationary disk 96 and is in permanent communication with the curved groove 98. This suction. pipe may be in the form of a flexible hose and is connected at its upper end with a pipe I04, which leads to a source of vacuum or suction, such as a suction pump I05. A two-way valve I06 is connected in each pipe I04, and is adapted to alternately place the hose I03 in communication with insuring a quick and uniform application.

In Figure 20, I have shown a slightly modified form of the invention, whereby the groove 98 is alternately placed in communication with the source of vacuum, or in communication with the atmosphere. This means comprises a valve which I preferably mount adjacent to each valve disk 96, and rigidly attach thereto. This valve comprises a casing I09, having oppositely arranged vacuum supply ports H0 and III. The port I I I is in permanent communication with the curved groove 98. The casing also has a vacuum breaking port H2, in permanent communication with the atmosphere. A valve body H3 is mounted to turn within the casing I09 and has a main'port II4, to connect ports H0 and ,III, and a branch port II5 also adapted to register with the port III, while the remote end of port II4 will register with port H2. The valve body means may be employed, in the form of a dash II 3 is turned by means of a lever II6, rigidly connected therewith. The downward movement of this lever is limited by a stationary stop I I1 carried by the casing I09. The lever is moved downwardly by a spring II8, so that port II4 will connect ports H0 and III. The valve body II3 preferably has suflicient frictional engagement within the casing I09 and the spring H8 is of such a strength that it will return the lever II6 to the lowered position, relatively slowly, for a purpose to be described. If desired, additional pot to retard the downward movement of the lever due to the actiorrof the spring II8. I The lever II6, when the carrier approaches its lower-- most position, engages a stop. II9, which is attached tothe adjacent track 26, swinging the outer end of the lever upwardly and turningthe valve-body II3 so that groove 98 is placed into communication with the atmosphere through the port H2 and at the same time is placed out of. communication with the suction pipe I03.

I also provide suction means to return the ball or balls to the return runway. This means is shown as embodying a preferably rigid tubular arm I20, provided at its forward end with a rubber suction cup I2I. The tubular arm has connection with a suction hose I22, connected with the source ofsuction. The numeral I23 designates a vertical shaft, which is capable of tuming upon its vertical axis, and this shaft is provided at its upper end with knuckles I24, to receive therebetween the knuckles I25 formed upon the tubular arm I20, the knuckles being pivotally connected by'a horizontal pin I26. The tubular arm I20 may therefore be swung'in a vertical with, and swung horizontally by a crank I26,

rigidly secured to the vertical shaft I23. Any

suitable means may be employed tomove the cranks I25 and I26.

The operation of the apparatus is as follows: The bed of the bowling alley having been raked and all pins removed therefrom, the carrier is 'in the uppermost position, and the pins 25 are introduced into the guards 'II, with their head ends down. The pins-25 may be fed'into the guards II by any suitable means, or they may be introduced therein-manually. When the carrier is thus in the uppermost position, the interior of the pipe or tubular frame 50 is connected with the source of suction, since port I00 is in permanent communication with the groove 98, and each valve body I06 is now in a position to place pipe I03 in communication with the source of vacuum I05; When the pins 25 are thus introduced into the guards 'II they are free to swing upon the upper rings I2 so that they will automatically assume true vertical positions, and when they descend into the guards II their head ends engage :the stems I0, opening the valves 69, and thereby supply suction to within the several suction cups 65. The suction cups now securely engage and hold the head ends of the pins. This suction remains supplied to the cups 65 and the carrier is started upon its descending movement by the operation of the motor 93, causing the cables 9| to pay out, the carrier descending by gravity. The movement of the carrier is at a proper speed to enable" the same to function correctly and should be relatively slow. As the carrier begins to descend, the setting frame 50 is arranged uppermost and the pins are held with their butt ends uppermost. When the carrier moves downwardly sufliciently, the roller I02 at each side of the carrier enters the inclined branch 30 and the 'arm' or crank IOI is accordingly shifted from its vertical position to an inclined position, which effects a tilting of the carrier upon its horizontal transverse axis as defined by the shafts 84. By the time the roller I02 reaches the curved portion 32 of 'the portion 29, the carrier has been tilted so that its weight tends to complete the tilting action, and the arm IN is now arranged above the setting-frame 50 instead. of below it, and as the carrier continues on its downward movement, the arm IOI continues to approach the vertical, until'the roller -I02 again .enters the track 26 below the branch 3I, at

which time, the carrier willhave been inverted and will be in a true horizontal position. When the roller passes through the branch 30, as explained, it is deflected by the. gate 42 into the branch 30 and passes the gate 35 and passes the gate 43 shifting it to aposition to cover the adjacent portion of the track 26 and enters the track 26 belowv the gate 43. *The carrier now continues to move downwardly until the. butt ends of the pins are placed upon the bed, directly over the spots and are -in concentric relation thereto, at which time the motor is stopped and rier starts to move upwardly, the valves I are operated to place the interior of the tubular spotting frame 50 in communication with the 5, atmosphere through the ports I01, "and cutting on communication with the source of suction or vacuum whereby the suction withincups Iii is completely broken. The pins being properly spotted and released, the motor is started to raise the carrier so that it will be out of the way when the player throws the first ball. As the carrier moves upwardly, the roller I02 will. travel in the track 26 until it engages the gate 03, previously shifted to the left, and the roller will is therefore travel throughv branch 3I, curved portion 32 and branch 33, and will pass gate 30 and reenter the vertical track 26 near and'beneath the gate 34. The arm IOI will thus turn the carrier in an opposite direction for one-half of 20,, a revolution to completely again invert the same, whereby the resetting frame 46 will be in the lowermost position and the setting frame 52 in the uppermost position. The motor is stopped and the carrier brought to rest at this point.'

- With the carrier held at this elevation, the player rolls the first ball, and if some of the pins remain standing, they must be raised, 'the bed raked to remove the knocked down pins, and the raised pins reset. Assuming that all. of the pins have not been knocked down, the motor is again started and the carrier descends to bring the resetting suction devices I0 into proper,- engagement with the head ends of the pins. -When each suction device I4 is brought into 86 proximity to the head end of the pin, three of the suction cups 11 will engage the head end of thepin and the valve stems 80 will contact with the head end of the pin, opening the valves 19, whereby the suction cups 11 are placed in communication with the source of suction, the valves 806 being now in a position to connect the pipe I03 with the source of'suction I05 and to cover the ports I 01. After this occurs the motor is stopped and the carrier is brought to rest, and the motor is reversed and the carrier raised.

. When the carrier was lowered, to bring the suction devices 14 into engagement with the head 1 ends of the pins, roller I02 travelled through the vertical track 26 and swung gate 43 to the right,

50 and upon the upward'movement of the carrier,"

last referred to, the roller I02 will. not enter branch 3|, but travels vertically through track 26 and will stop near and beneath the gate 34,

' as stated. While the carrier is thus elevated, 55 the bed is raked to remove the knocked down pins. This raking may be done by any suitable means or may be enacted manually. After the .bed is thus raked,- the motor is again started and the carrier is lowered, the roller continuing to v 60 travel in the vertical track 20 and passing gate 43 which is now at the right, Figure 5; The downward vmovement of the carrier continues .,until the pins have their butt ends set upon the When this occurs the carrieris stopped, valves I06 are manipulated to place the interior of the cups I1 into communication with the atmosphere and to break their communication withthesource of suction I05, whereby the vac,-

-uum or suction in the cups ,I'Lis completely the playing of duckpins, the carried-would again move down so that the-suction cups 11 would engage the remaining upstanding pins aud elevate the same permitting of the raking of the bed, and again reset these pins. The carrier would then move upwardly after resetting the 5 last pins and would continue its upward movement, the roller I 02 passing the gate 42, until the carrier reached its uppermost starting position,-

Figure 1, at which .point the pins would again be introduced into the guards I2. If only two 10 balls are employed, when the carrier was elevated aft'er resetting the pins for the first time, the

upward movement of the carrier'would be continued 'until the uppermost position were reached, for reloading with the pins. rier is now returned to the initial-starting posi; tion and the cycle of operation would be repeated.

The operation of the motor and the movement of the valves I06 may be manually effected, or 20 any suitable automatic means may be employed 5 to actuate the same, in. proper timed order.

' In Figure 20, I have shown the automatically operated valve to be substituted for the valve I06. When the carrier approaches its lowermost 25 position, to spot the pins, the lever II6 engages the stop I I9, and valve body I I3 is turned thereby 'normalposition. In a similar manner the suetion is automatically broken after the suction devices I! have reset the pins, and before the 40 cups I'I disengage the pins and remain unbroken until these cups have moved out'of engagement with the head ends of the pins.
