INTRODUCTION
Those who plan to use electric motors need information on types, characteristics, and efficiencies of motors and on advantages of each type. It is the purpose of this bulletin to give information that will enable us to make proper selection of electric motors for various purposes and to operate them properly. Regardless of type, the electric motor possesses certain advantages over other stationary power machines, particularly that of easy starting. Cold and [...]

Foreword This restoration was originally chronicled on the The Iron Giants: Matcher Resto Race of 2012! on the Old Woodworking Machines Forum. The Vance 2½ planer matcher was Keith Rucker’s entry into a completion to see who could restore their planer-matcher first. The Restoration Part 1 (2012) Jun 03, 2012
The matcher that I will be working on does not actually belong to me - it is in the collection of our local museum - the Georgia Museum of Agriculture (formally the Agrirama) [...]
Farm Motors-Electric Motors Principal Parts of Motors The principal parts of all dynamo electric machinery, whether they be generators of electricity or motors driven by electric current, are: 1. A magnetic field, commonly called a field, whose function it is to furnish magnetic lines. In the earlier machines this consisted of a two-pole magnet but the modern generators and motors are provided with four or more poles. The reason for this is that a more compact machine can be produced. A [...]

[...] the exhaust valve and allows a fresh charge to be drawn in. This company furnishes both hot-tube and electric igniter for all their engines, so that failures shall not occur by the disabling of one or the other of the igniting apparatus. The governor is of the horizontal centrifugal type, revolving on the main shaft, and by a lever connection produces a lateral movement of a rolling disc attached to the lever of the exhaust push-rod. The lateral motion of the governor-controlled disc rides the disc on to or off the exhaust cam on the reducing-gear [...]

The various types of gas tractors, to be described in another chapter, are usually started on gasoline and operate with kerosene or with solar oil, which is a heavier distillate than kerosene. In general, an engine running on petroleum fuel other than gasoline is more difficult to start and requires greater care and more frequent cleaning of valves and pistons. For small engines gasoline [...]

[...] and recurrence to the descriptions of engines already given in the preceding papers will show that electric ignition, flame ignition and ignition by incandescence all have found a share of favor in the eyes of gas engine builders. Electric ignition has been practiced either by the spark method, as in the early Lenoir engine, in which, at the proper times, an electric spark was made to pass between two electrodes within the cylinder, or by the incandescent wire method, in which an electric [...]

The governor is of the ball type, running direct from the secondary shaft by a bevel gear, and through a bell-crank lever and arm controls the gas-inlet valve. Fig. 69 shows the arrangement more in detail and also the great convenience in gas engines, a cap plug for quickly removing the valve and an inspection plug at the side of the valve [...]
[...] Ohio, many of whom have gone out of business or evolved with the times. My curiosity about Kneisley Electric Company began when I bought a Yager planer in March 2007. Publication reprints on the .com site and discussions here provided a little information. What was known was that these planers were sold or badged by at least four different companies, Kneisley Electric Company in Toledo, Foster Manufacturing Co. in Buffalo, NY, Montgomery Wards and Astro Wood Planer Co., Bristol Conn. Later I learned that Freeman Supply in Toledo sold the [...]
[...] are evidently built for hard service. Their proportions are such as will adapt them successfully to electric lighting and railroad service. In the way of foreign engines, an interesting type is shown by F. Schichau, of Ebling, Prussia. This engine is 22¾ x 37½, x 57¼ x 27½ inches vertical, triple-expansion condensing, with three cranks, and at 100 revolutions per minute is rated at 1000 horse-power. At a speed of 180 revolutions per minute the power runs up to 2500 horsepower. Steam is to be used at a pressure of about 180 pounds per square [...]
This page shows how the belt can be changed on a Walker-Turner 900 series drill press. These photos were taken during the process of a full restoration of a WT 936, which is a floor model drill press with a production table. The same process can be used on any 900-series machine. Walker-Turner 900 drill presses used at least two different designs for the upper bearing retainer that captures the bearing mounted on the top of the spindle pulley. One version uses a machined steel sleeve [...]

With so many different makes, models and machine types it would be nearly impossible to cover everything here. If you are looking for specific information please feel free to take part in the OWWM discussion group. In the mean time, this guide can act as your jumping off point and hopefully get you started. 1 - Getting Started The very first thing you will need to do is, find out the name, rank and serial number of the machine. This will aid you later when [...]

In 1886 the Westinghouse Electric Company was formed for the manufacture of lamps and electric lighting apparatus, Mr. Westinghouse having become interested in the subject. The business rapidly developed and in 1889 and 1890 this company absorbed the United States Electric Company and the Consolidated Electric Light Company. In 1891 all these properties were reorganized into the Westinghouse Electric [...]
[...] the 1939 but it's still a fine saw none the less. I have not paid much attention to the various Delta drill press lines as there were so many through the years it's darn near impossible to focus on one popular model. I also lack a number of catalogs making a drill press write up difficult. Similarly, lathes suffer the same fate. The Delta Specialty Company began business in 1919 in a one car garage at 969 Louis Avenue on Milwaukee's near northwest side. It was called the Delta Specialty Company until the early thirties. One of the co-owners, [...]
[...] ornate balustrades for stairways, and other rococo decorations. It must be remembered that in those days electric and gas power were not in practical use; you had to depend on steam, water or foot-power. While increasing production of their scroll saw, the Barnes brothers recognized the need in their own shop for other power tools - a circular saw, a foot-power wood lathe, a foot-power former and mortiser. These they proceeded to develop. And here again, machines designed to answer their own requirements were discovered to have a wide application, and so these new tools [...]

The owner of the land agreed to sell it to the Board of Trade for a cash price of $350. Within a few days, all of the necessary arrangements were made, and land was purchased on behalf of the Crescent Machine Company. In addition to purchasing the land, the Board of Trade agreed to do the necessary site preparation on the property where the plant would be built. The site preparation, consisting of fill work, was estimated to cost an additional [...]
By Roy Wall Here is photo of the PM 1150. A classic 15" drill press that is durable and serviceable. The following sequence is designed to help a new owner replace ALL bearings and thus give the drill press a "new life" for the next 20 + years, even more in a hobbyist shop-provided the motor is in good working order. This is a 1966 PM 1150. It has a Robbins & Myer 1 hp -1725rpm -1 ph motor; currently wired for 110v (a 220v wiring diagram is listed on the motor). A newer 2002 Sears 15" model is in the background for scale. This is an [...]

[...] certain quantity of this mixture had entered the cylinder, the slide valve shut off the supply and an electric spark from an induction coil kindled the gas and caused an explosion which drove the piston to the other end of its stroke. Arrived there, at the left end, a second slide allowed the products of combustion to escape while the fly wheel, by reason of its momentum, went on and moved the piston in the opposite direction, from left to right. While it moved in this direction, the explosive mixture again entered and was ignited as before, and the piston completed its [...]
[...] will look at Part B: Crescent Jointer Guard Part B with Drawing On this piece, you will need to drill two 3/8" holes and drill and tap a 1/2 x 13 hole. Also note that the top surface in the picture should be machined flat. While not noted above, it's mating surface on Part A should also be machined flat - they will rotate on each other. Part C

Fig. 25— The Foos Gas Engine, Igniting Electrodes The arrangement of these will be better understood from Fig. 25. When the two ends X and Y are brought together, as shown in this illustration, the electric current from the battery provided with the engine is closed, and when they are then quickly separated, [...]

The bearing were mounted back on saw and the wheels were installed. The upper bearing assembly installed and ready for the wheel Lower bearing assembly ready for wheel and pulleys (shot from pulley side) 1.2 - Installing New Tires The next step was to install new rubber tires on the wheels. Rubber tires are necessary so that the band saw blade does not ride directly on the cast iron wheels, which [...]
[...] the whole outfit. These circumstances have, in a great measure, helped to stimulate the improving of electric igniting devices, and several of them are now affording very satisfactory accounts of themselves. This much may already have been gathered from what has gone before. With the electric igniter there is, of course, to be considered the expense of the battery which furnishes the electric current, but this has been claimed, and with good reason, to be a very small proportion of the whole operating expense,—a [...]
