When You Buy A Micrometer Buy A "Slocomb" The Reasons

Accuracy is the first and foremost requirement of a good micrometer—close accuracy that will stay close throughout the life of the tool. Slocomb Mi-crometers have been leaders for over twenty years, because they are positively accurate and there's ample provision for adjustment in case of wear. Moving one of the halves of the two-piece adjusting nut an amount equal to one division on thimble adjusts the screw 0.00025 inch surely and simply. The "Slocomb" is also the longest wearing micrometer on the market. On the 1-inch "Slocomb" the thread bearing is 5/8" long, twice the length of that provided on any other similar tool. The measuring screw is made in one piece from annealed tool steel. Decimal equivalents are stamped on the thimble. Catalogue 14-M gives further reasons why you should buy a "Slocomb." Send for one today—you need it on file if not for immediate use.

The Wear and Tear is Little and Maintenance is Low on The Gear Shaper
Every machine carries a maintenance cost ; but the lower it is, the better—for the machine, the man who built it, and the man who uses it. We are proud of the Gear Shaper maintenance record, the low cost and the little wear and tear involved in its operation. An instance of Gear Shaper durability is shown above, a machine which has been in constant use for over fifteen years in the factory of Wilson & Short, Detroit, Mich.

In a recent letter from this concern Mr. Wilson says : "You may be interested to know that the Fellows Gear Shaper which we purchased about fifteen years ago is still giving good satisfaction. "We use the machine for cutting internal gears for our automobile starters and we are sure there is no other practical way to produce these gears of the quality we require." The structural design of the Gear Shaper is such that cutting stresses are taken in direct tension and compression. On some types of gear-cutting machines the cutting stresses are carried through the feed gears, which puts all of the mechanism under strain while the machine is working. In the Gear Shaper the cutter and work are geared to rotate steadily together. There is no stopping or starting at high speed. Every movement is conducive to long life.

Let us send the Gear Shaper books and more information.

November, 1914 MACHINERY pg 79 Here's a Handy Machine for Finishing Castings Forgings and other Chuced Work. Have you a quantity of work in your shop such as finishing small castings, forgings, irregular shaped pieces or chucked work? If so, there is a field where a B. & S. Plain Screw Machine can be used to distinct advantage. These machines are particularly well adapted to producing this class of work which can be held in a chuck or collet or clamped on a faceplate. They are also suitable for manufacturing screws, studs and small parts from bar stock already cut into sections. Ample driving power enables them to easily handle all work within their capacity. Readily set up, they can be used to advantage on short jobs, and once set up require little attention. In addition, handy design makes for convenient operation. We build three sizes of these machines, the largest of which, the No. 6 Plain Screw Machine is shown below. Note how convenient and central is the full control. All working parts are within easy reach of the operator's hands. The front of the machine is free from gear cases and revolving driving shafts, all driving mechanism being at the back of the machine out of the operator's way. A careful consideration of the possibilities of this machine will doubt-less mean a substantial saving in your costs. Send for a descrip-tive circular giving full details.

Two Foote-Burt Cylinder Borers 900 Single Cylinder Engine Castings Time 10 Hours. THIS is a remarkable case of production, cylinder boring, in one of the big automobile shops. The machines are Foote-Burt Cylinder Borers. The cylinders are held four at a time in a special jig under each machine. The diameter of the bore is 41/2" and the depth 91/2". The amount of material removed from a side is 3/32" and 45 cylinders are turned out from each machine per -hour, or 900 from the two machines in 10 hours. It is a remarkable performance and shows the Foote-Burt Cylinder Borers at their best. The cut is a stiff one for four spindles to take simultane-ously, and shows the rigidity of Foote-Burt construction. These machines are built for service such as this, and give it. We claim nothing that cannot be accomplished. Let us show you what these machines will do on your own work. Detroit Office—

Broaching for Profit-LAPOINTE MACHINES
T. broach for accuracy alone is good, but to broach for accuracy plus profit is better. And this is what you secure when you broach with Lapointe Machines—the closest possible accuracy at the most

profitable production rates. We have proved this to many men. We'd like to prove it to you.

Here's one instance. A 15-point carbon steel sliding transmission gear with a 1 1-4" hole and 4 keyways b-16" wide by 2 1-8". Two cuts are taken, roughing and finishing, and production on the finishing cut is 200 gear blanks in nine hours. Fast work ! Good work !

LANDIS POINTS WORTH KNOWING
LOCALIZED MANIPULATION. All levers are operated from one central position within easy arm's reach--eliminates fatigue and steps.
VARIETY INDEPENDENT SPEEDS. Indi= vidual work and traverse speed change levers, quickly and easily shifted (one by left hand and the other by right) while machine is in operation. No excuse for incorrect combination of speeds.
SIMULTANEOUS START AND STOP LEVER. One lever starts the work and traverse simultaneously, and its reverse movement stops both instantly.
POSITIVE QUICK SETTING TRAVERSE REVERSING DOGS. Simply slide (one by each hand) dogs to approximate position and use screw adjustment for fine setting.
AUTOMATIC SIZING DEVICE. In connection with the automatic cross feed of the grinding wheel is an automatic device which can be set to disengage the feed at a determined diameter on the work. This, in duplicate work, permits the operator to prepare work, etc., while grinding, also avoids frequent calipering.
CONVENIENT LOCATION OF GRINDING WHEEL CROSS FEED. Standing erect the operator can watch the wheel approach the work while feeding by hand elimi= ates bending and interrupting the feeding. QUICKLY OPERATED FOOTSTOCK SPINDLE. By simply pulling the footstock spindle lever with the right hand releases the center and leaves the left hand free to remove the work.
REVERSING TRAVERSE BY HAND. A single central lever starts, stops or reverses the traverse of the grinding wheel carriage, also automatically disengages or engages the wheel for traversing the carriage by hand.
INTERCHANGEABLE WHEEL CENTERS facilitate in the use of different grades of wheels.
TRUING THE GRINDING WHEEL. The wheel can be trued in any position without removing the work. LIMIT STOPS ON THE WORK RESTS. For grinding duplicate work, stops on the work rest jaw screws can be quickly set for limiting their respective feeds.

The Barber-Coleman No. 12, AKA (12-12) Hobbing Machine

These Features Help Reduce Your Gear Production Costs
Machine is extra heavy and compact, with weight carefully and properly distributed. Bed and column are of rigid box section. Hob slide is close to the solid bed. Work sets close up to spindle bearings in the work slide. Control handles are on one side. Hob slide is mounted on horizontal ways. Work arbor is horizontal. You can readily see how these features give ease of operation and ability to take fast, heavy cuts and those are what increase your rate of production and so reduce production costs. If you produce spur or spiral gears in quantities, you can cut costs by installing a B-C No. 12 Machine. Send samples or blue prints for estimated rate of production.

The BECKER No. 6 A Heavy Manufacturing Milling Machine
Where high production on plain milling is an object the No. 6 Becker Vertical Milling Machine "fits." It is built for heavy milling on duplicate manufacturing work and does not require a skilled operator to secure best results. The Ritter Dental Manufacturing Company of Rochester, N. Y., makes high-grade dental chairs. The bearing surfaces to which the pumping mechanism of these chairs is attached are milled on a Becker No. 6, and 100 castings are completed every twenty-five hours, including the time required to handle the heavy pieces, which amounts to nearly as much as the milling operation. The longitudinal feed of 50" and cross feed of 20" permits the milling of large work, and the vertical movement of the head is actuated by a powerful worm gear. An automatic stop which throws out the feed at any point and the quick return motion makes this No. 6 Becker especially valuable for vertical boring.
Many other features. Send for catalog.
