All units are made up of subunits and are assembled in oil-sealed housings. All shafts have integral keys bobbed from the solid, either four or. six keys ; and parts fitting on same are broached with Multiple Broaches. All shafts are supported on each end by high-grade Anti Friction Bearings. Shafts and gears are of heat treated alloy steel and gears have ground or shaved teeth. All Ball Bearings and moving parts are sealed against dirt, and are automatically oiled. pushed along the arm without using power traverse or hand traverse. Balance is not only essential on the Head Unit but is also maintained by having the face of the arm in line with the center of the column and having the center of the spindle and counterweight as near the face of the arm as possible. Perfect alignment and balance allows the arm to swing 360 degrees with the ease of fingertip pressure. The Carlton Head is in Perfect Balance LUBRICATION From a lubrication standpoint, the design and construction of Carlton Heavy Duty Radial Drills embody improved features which make increased production possible by reducing friction, wear, power losses, shut down, and renewals. Each unit has its own oil gauge which can be seen at a glance so that the foreman or operator can readily determine that the machine is receiving proper lubrication. All gears, shafts and bearings are enclosed in oiltight housings and run continuously in a bath of oil. Wherever horizontal or vertical shafts extend from the various units, oil leakage is prevented by centrifugal action. The oil is thrown off by oil slingers and then returned by oil grooves into the body of the unit, where it is then recirculated. There are n o packing glands which require constant attention to prevent oil leaks. BALANCE Balance in a machine tool produces ease of operation and perfect alignment. This is highly essential in making a day's work easy for the operator and increases production. A CARLTON Head Unit balances on the arm ways and can be pulled or Page 3

4 SPINDLE LOW-HUNG DRIVE The spindle is made of chrome nickel steel, hardened and ground. Large spindle anti-friction bearings to carry excessive loads and shock are used. Anti-Friction Thrust Bearings are used to take the thrust on the spindle, up or down, under drilling or backfacing pressure. Every part is lubricated with constant flowing oil, and is absolutely guaranteed not to leak oil. A continuous bearing is maintained on the spindle as the spindle feeds out of the Head. The spindle sleeve bearing extends to the extreme bottom of the Head maintaining bearing on the spindle as close to the cutting tool as possible. The Low Hung Drive permits an exceptionally large diameter spindle to be used, and the drive is applied on this large diam<!ter. Ti1e spiffu1e feed rack sleeve is at the top of the spindle and is always enclosed where it cannot carry dirt, chips, and water up in the Head Unit. The spindle is driven by an exceptionally large sleeve which revolves on large anti-friction bearings and the spindle slides in and out of this sleeve. The spindle drive gear is at the extreme lower part of the Head and drives on the largest diameter of the spindle as close as possible to the cutting tool. The spindle sleeve and counterweight have generated teeth and are balanced on a hardened pinion gear mounted on ball bearings enclosed in an oil tight case. HEAD The Head contains mechanical spindle speed changes and a neutral position of the spindle. Shafts and gears are of heat treated alloy steel and gears have ground teeth. An oil filter is provided to cleanse the oil of foreign matter. An oil pump submerged in oil at the bottom of the Head is provided for forcing the oil to all gears and bearings, and the flow of oil is indicated by a sight gauge near the top of the Head. On the side of the Head a second gauge is provided for indicating the correct oil level in the reservoir. The Head is mounted on Ball Bearings and rolls along the arm on a hardened and ground steel Armway. FEED The feed unit provides p o w e r feed changes. These are controlled by levers and are indicated by a direct reading dial. A positive drive clutch is used to engage and disengage the feed. REVERSE Forward and reverse of the spindle is accomplished through multiple disc clutches running in oil. A brake automatically stops the spindle when in a neutral position. QUICK RETURN Spindle has automatic safety stop, both up and down at its maximum travel, also depth dial for setting to any predetermined depth f o r drilling. HEAD CLAMP A positive fool proof head clamp is provided. By fingertip control the head is clamped to the arm absolutely tight. Page 4

5 BASE The base is heavily ribbed to its full depth. Heavy longitudinal and transverse ribs run the full length and width of the base. These are closely spaced and form a series of box sections, and give great strength and rigidity to same. Spacious oil channels are provided to drain the coolant back through strainers into the reservoir. The reservoir is cast in the rear of the base behind the column where it does not weaken the base. This also makes the reservoir easy to clean. Heavy bosses to receive the column screws are cast integral with the ribs in the base. These extend the full depth of the base. COLUMN The inner and outer columns are close grained semi-steel castings. The inner column is heavily ribbed down to the bottom where the ribs extend directly to the bolt holes which attached the column to the base. The inner column has an exceptionally large thick flange. Both inner and outer columns are designed and proportioned to give the greatest possible resistance to drilling strains. The outer column revolves on anti-friction bearings. The arm swings so easily it can be moved by fingertip pressure. The outer column is of the split skirt type and has an exceptionally large clamping area. ARM The arm is a close grained semi-steel casting which has a large, ribbed, full box section above the arm ways. This is made possible only by the Carlton Low Hung Drive type of Head. Dove tails at the top and bottom of the arm ways locate the head and keep it in perfect alignment at all times. HEAD TRAVERSE The power traverse is an individual unit, operated by a push button, for traversing the head along the arm. A safety stop automatically disconnects the motor which operates the unit, when the head reaches the maximum travel on arm. A safety stop automatically disconnects the traverse unit when the head is clamped to the arm. This unit springs instantly into motion when contact is made with the controlling push button; and when contact is broken, by releasing the push button, the entire unit is at rest. ELECTRO-HYD RAU Ll C COLUMN CLAMP The electro hydraulic column clamp unit is an independent self-contained unit mounted under the back of the arm in a protected position. The unit will clamp or unclamp the column instantaneously and is at rest after the cycle is completed. No pressure or current is required to keep the column clamped or undamped. ELECTRICAL EQUIPMENT The electrical equipment is wired with a high factor of safety conformir,g to all sp.::cifications of the National Electrical Code. The electric swivel unit is mounted in the column in a totally enclosed and protected place. This unit allows the arm to be revolved continuously 360 degrees. There are no wires which can be twisted or broken by revolving the arm. SPECIAL BASES Carlton Radial Drills can be furnished with any type of Special Base, such as Double-End, Right Angle, 3-Way, 4-Way, Half-Round and Round. Portable or Track Type bases also available.

6 ADJUSTABLE SPEED D. C. MOTORS Controlling Epindle speed changes by a Rheostat allows the operator to change or select the proper RPM of the spindle while the cutting tool is at work, thus obtaining the correct peripheral speed to the cutting tool at all times. The variation of spindle speeds controlled by a Rheostat are smaller and more selective than change gears where the spindle speeds obtained by gears being in Geometric progression. In geometric progression each succeeding speed is multiplied by a constant ratio and when the higher range of speeds are reached the difference between each speed becomes greater and greater. The use of an adjustable speed driving motor replaces many mechanical speed changes necessary with a constant speed driving motor. The adjustable speed motor eliminates many gears, shafts, bearings, and reduces friction. Clc~e graduation of spindle speeds are obtained by this motor drive. Correct peripheral spee<i for any diameter cutting tool is available. Spindle speed is adjusted correctly while the cutting tool is at work. It is not necessary to disengage the feed, stop the spindle, shift the gears, start the spindle and re-engage the feed to change the RPM of the cutting tool. Machines can be furnished with adjustable speed motor or constant speed motor. 8' Arm, 19" Column Carlton Radial Drill Above: Front View - Below: Rear View Universal Table Page 6
