The Adams Milling Machine for Planers
consists of a number of units which transform a planer into a tool of multiple uses.
It takes up no additional floor space and does not interfere with normal planing operations. At a small investment, it provides many of the advantages of a planer type miller and will perform many operations that cannot be handled on the ordinary type of milling machine.
It can be used to drive plain or formed milling cutters, singly or in gangs, keyway cutters, face mills, slab mills, T-slot cutters, circular saws, end mills, boring heads, and gangs of cutters to finish racks at a single pass.
Cutters can be operated on horizontal, vertical or angular surfaces, the head being quickly set by means of the graduated scale on the saddle.
Fig. I—Milling a keyway in a long shaft.
Planing, milling and boring operations can frequently be combined at a single setting of the casting and at a considerable saving in time.
The large surface of the planer table permits handling long or bulky work. Smaller parts can be clamped over the entire length of the table, finished parts being removed during operation, thus affording practically continuous milling.
Hundreds of installations throughout the world have demonstrated the usefulness of the Adams Milling Machine for Planers. It can be profitably employed in any shop having planer equipment.
WHAT IT DOES
WHAT
IT IS
Milling Heads
The Adams Milling Head is a rigid, compact and powerful unit for driving the milling cutters.
It is in all respects a precision tool, built for long and efficient service. It is effectively sealed against entrance of dust and leakage of oil, and it requires no attention beyond the occasional addition of lubricant.
THE DRIVE consists of a hardened steel worm and a phosphor bronze worm gear.
THE SPINDLE is hardened and accurately ground. Both ends of the spindle have standard B. & S. taper, with a clutch recess for engaging cutters or arbors.
TIMKEN BEARINGS (Precision type) are used on both spindle and worm shaft to adequately take care of both radial and thrust loads.
PRECISION OIL SEALS effectively retain lubricant at all positions of the milling head.
Fig. 2—No. 3 Adams Milling Head mounted on saddle for direct motor drive.
THE MOUNTING of the head on the saddle is accomplished by means of a circular T-slot, permitting the head to be swiveled for horizontal, vertical or angular milling.
The center of the swivel is in line with the center of the worm shaft, so that driving centers remain constant regardless of the position of the head.
THREE SIZES are available, selection of which is dependent upon the size and rigidity of the planer and the class of work to be accomplished.

*For head in horizontal position. When spindle is vertical, larger cutters will pass under the planer rail. Page 3
Saddles
THE SADDLE is in all cases supplied to fit the planer rail, conforming with a templet furnished by the purchaser.
A GRADUATED SCALE, to degrees, is applied to each saddle for setting the head to any desired angle.
I—THE PLAIN SADDLE is the type used in connection with belt driven heads.
2—THE SADDLE FOR MOTOR DRIVE (see Fig. 2). This saddle has an integral bracket for supporting the
driving motor. Connection from the motor to the worm shaft is usually made with sprockets and silent chain.
Fig. 3—Milling Head applied to saddle with vertical adjustment.
3—THE SADDLE WITH VERTICAL ADJUSTMENT (see Fig. 3). This is a double sliding saddle, permitting vertical adjustment of
the head independently of the planer rail. The amount of adjustment provided is as follows:
No. 1, 8 inches; No. 2, 10½ inches; No. 3, 12 inches.
4—THE SADDLE FOR MOTOR DRIVE, INCLUDING VERTICAL ADJUSTMENT. This is a combination of saddles Nos. 2 and 3. In this design, the crank is brought out to the side of the saddle, in convenient operating position.
SPECIAL SADDLES are available to bring the spindle
center below the rail or farther out than standard. Right angle saddles with or without head swivel can also be furnished.
Outer Bracket
THE OUTER BRACKET is a necessity when using long horizontal arbors (see Fig. 1). It incorporates a Hyatt bearing with special closure and, like the saddle, it is furnished to fit the planer rail.
Belt Tightener
THE BELT TIGHTENER (Fig. 4) is almost invariably required with the countershaft. It serves to keep the belt tight at all positions of the milling head and enables the head to be fed vertically or transversely into the work while in motion.
and Belt Tightener.
Countershafts
COUNTERSHAFT EQUIPMENT (Fig. 4) includes a shaft 7 feet long to permit driving from a convenient place on the lineshaft; also two
hangers, two friction clutch pulleys, a driving pulley and three pulleys for the milling head. Specifications are as follows:
| NO. I | NO. 2 | NO. 3 | |
|---|---|---|---|
| Shaft diameter, inches | 11/16 | | |5/|6 | 1 15/16 |
| Clutch pulley diameter, inches | 10 | 12 | 12 |
| Clutch pulley face, inches | 5 % | 61/8 | 8 5/16 |
| Drive pulley diameter, inches | 14 | 16 | 1.6 |
| 8 | 10 | 10 | |
| Pulleys for milling head, diameter, inches | 10 | 14 | 14 |
| 14 | 16 | 18 | |
| Pulleys for milling head, face, inches | 3¼ | 5 3 /8 | 6¼ |
Feed Mechanisms
For milling operations, it is, of course, essential that the normal planing speeds be reduced materially. This is easily taken care of by the feed mechanisms we are prepared to furnish.
FEED MECHANISMS FOR BELT DRIVEN PLANERS (Fig. 5). This device operates in conjunction with the planer countershaft. It consists essentially of a split worm gear bolted to the planer countershaft and engaging a worm which is driven by a frction disc through a leather friction wheel.
The friction disc is belted to the lineshaft, and a crank rod is used to shift the friction wheel on the disc to change speed. Table speeds of from 0 to 6 inches per minute in either direction are available.
The worm can be shifted out of engagement with the worm gear by a convenient lever,
making it a simple matter to change from milling to planing and vice versa.

Fig. 7—Traversing Head
THE TRAVERSING HEAD is a very useful tool when applied to the vertical spindle milling head. It saves considerable time on various boring and turning operations.
FEED MECHANISM FOR MOTOR DRIVEN PLANERS (Fig. 6). This device is a special form of variable speed gear box, to be interposed between the driving motor and the planer.
It incorporates a direct clutch connection for planing purposes and a variety of reduced speeds for milling.
Timken bearings are used throughout and the entire mechanism operates in oil.
Fig. 8—Inserted Tooth Face Mill
ADAMS FACE MILLING CUTTERS are made in diameters from 6 inches up. Cutting tools are of the finest grade high speed steel, mounted in an angular position in the forged steel body. Cutting rake is most efficient, and ample chip clearance is provided.

Fig. 9—The traversing head being used for boring and circular T-slot cutting. Here is an outstanding example of how planing, milling and boring operations can be performed at a single setting of the work.
- Fig. 10—Machining the edges of two castings simultaneously with a large diameter side milling cutter. The operation is nearly continuous, for while one casting is being milled, another is being chucked and a finished one removed.
- Fig. 11 A gang milling operation on small parts. Practically continuous milling is obtained by using a special false table which can be turned end for end. While the cutters are operating on one set of castings, the finished lot is removed and a new lot is placed in the fixture.
