ALLENAIR ROTARY INDEX TABLES are precision indexing mechanisms . . . unsurpassed in accuracy, perormance anddollar value. We know o no other Tables o equal accuracy and quality available at comparable prices.

Every detail o construction is designed to increase durability and eciency, and provide or long, trouble-ree lie. Allparts susceptible to wear are careully hardened. Bronze and roller bearings are incorporated. Working parts completelyenclosed to protect against dust, dirt, and chips.

The Tables eect substantial savings in time and money in a wide variety o applications. For example, the Tables permitast, automatic eeding o parts to tools in machine and assembly operations. Parts can be loaded and unloaded whilemachining operations continue. Other applications include cleaning and positioning operations, as well as use in con-junction with conveyor drive units.

ALLENAIR ROTARY INDEX TABLES are available in a COMPLETE PRODUCT RANGE o our basic models, and eachmodel can be supplied with any one o the ollowing operating options.

1) As a basic Table with no operating valves. A 2-way or 3-way valve can be mounted on the rear o the drive cylinderas an option. (See Basic Table Illustration, Page 100).

2) As a basic Table with a Pilot Timer Valve (PTV4), a 2-way valve (V2), and piped with fexible air hose ready orcontinuous automatic indexing. (See Pilot-Timer Control Circuit Illustration, Page 100).

3) As a basic Table with a Single Solenoid Bleed Pilot 4-way Valve (VSESA-AAS-1/4), a 2-way valve (V2), and piped withfexible air hose ready or use. (See Solenoid Bleed Pilot Control Circuit Illustration, Page 100).

4) As a basic Table with a Single Solenoid Pressure Pilot 4-way Valve (VSSAP-AAS-1/4), a 3-way valve (V23), and pipedwith fexible air hose ready or use. (See Solenoid Pressure Pilot Control Circuit Illustration, Page 100).

5) As a basic Table with a Double Pressure Pilot 4-way Valve (VAP-1/4), a 3-way valve (V23), and piped with fexible airhose ready or use. (See Double Pressure Pilot Control Circuit Illustration, Page 100).

6) As a basic Table with a Double Bleed Pilot 4-way Valve (VSA-1/4), a 2-way valve (V2), and piped with a fexible airhose ready or use. (See Double Bleed Pilot Control Circuit Illustration, Page 100).

For Allenair TIME-A-VALVE see Page 87. A solid state Electronic Timer, integral with Allenair Solenoid Operators.The standard 24 notch index plate can be set by means o bafe plates to allow 4, 6, 8, 12 or 24 indexes. Special indexesrom 5 to 100 are available. A Flow Control Valve is also urnished on all models to control indexing speeds. Standard andoptional Top Plates, o mild steel, are readily workable, and are precision ground, fat and parallel, to within .002 T.I.R.

INDEX PLATE

The standard table can be set to index90 (4 index), 60 (6 index), 45(8 index), 30 (12 index), or 15 (24index). Since the standard index plate

has 24 teeth, bafes are used toprevent loss o index, that is, toprevent the pawl rom engagingimproper teeth When less than 24index is required. These bafes arevery reasonably priced and alwaysavailable rom stock. The changeoverrom one index setup to another canbe made rom the top o the indextable, usually in less than 15 minutes.

NOTE: For clarity and explanation this illustration is shown without top plate and rider plate.

GEAR AND RACK CONSTRUCTIONA rack attached to the stainless steel pistonrod drives a gear which carries a pawl toactuate the index plate. Only a rack and geardrive can transmit the straight line motion othe air cylinder to the necessary rotary motionwith ull power throughout its cycle. Therack is supported against thrust by two roller

bearings independently o the piston rod.Rack, gear, pawl and index plate are allcareully hardened.

MODELS 725:These models are designed or rapid indexing under rather light load conditions, the maximumindexing load being 60 Ibs. with either the standard 7-1/4 or optional 10 dia. Top Plate. Two styles are available. Model 725-G permits piping o airto the top o the Center Stud, or actuation o small air operated devices such as air chucks, collets or clamps, while Model 725-E does not. Both mod-els have spring tension on the Feed Pawl, which insures constant and proper engagement with the Indexing Plate. A dual purpose Mounting Baseenables horizontal or vertical mounting, and both styles are available in clockwise or counterclockwise rotation. A hole through the Center Stud (9/16dia. only) is available as an option on Model 725-E.

MODEL 11-E:This model, being larger and heavier than Model 725, is designed or more rugged operations. The maximum indexing load is 100Ibs. with the standard 11 dia. Top Plate and 80 Ibs. with the optional 16 dia. Top Plate. Spring tension on the Feed Pawl insures constant and properengagement with the Indexing Plate. Both clockwise or counterclockwise models are available. A hole through the Center Stud (9/16 dia. only), isavailable as an option.

MODEL 11-F:This is the heaviest duty model in the line, the maximum indexing load being 180 Ibs. with either the standard 11 or optional 16dia. Top Plate, and 100 Ibs. with the optional 20 dia. Top Plate. One o its outstanding eatures is the Positive Locking Device, which securely lockstheFeedPawltotheIndexingPlatebyaninternalover-centerlatchingmechanism.Thisdesign,togetherwiththeoptionalHydraulicCheck,allowstheTabletoperformatthehighloadlimitsspecied.TheHydraulicCheck(CODETHC),whichisadjustable,cushionsapproximatelythelast5ofrotation and helps to control the shock o heavier loads.Twoadditionaldriveoptionscanbeaddedtothismodel.OneistheTandem-in-LineCyl-CheckDrive(T-2-1/2x4-CHTFLH-5,CODECHD)whichgives hydraulic control and provides precise, constant, smooth indexing. The second optional drive employs a Tandem Cylinder (ETT-2-1/2 x 4, CODE

TCD). This provides higher torque (as dierentiated rom index load) than the standard drive cylinder. A hole through the Center Stud (9/16 dia. only)is also available as an option.

MODEL 11-EF:This model is almost identical to Model 11-F The basic dierence is that on Model 11-EF we use the Model 11-E Index Plate, andincorporatethePositiveLockDeviceofModel11-FThisallowsforslightlyfasterindexing,butthetwooptionaldrivesandHydraulicCheck(aslistedor Model 11-F) are not available.
