Collins & Greenwood saw All eight pictured examples have legs bolted to the beds. All eight of these saws have cast iron wheels. Patent dates are recorded as being cast into six of these eight saws. Neither the Collins and Greenwood saw or the Rogers saw has a record of a patent. Indeed, the C.B. Rogers company—active from around 1841 to 1897- held no patents on band saws. The Collins and [...]
[...] the correct heater for your motor, based on the motor’s current and the contactor’s NEMA size. For example, the N-38 heater is rated at 23.6 Amps with a NEMA size 3 contactor, but only 19.1 Amps with a NEMA size 1 contactor. Also, different series within a single manufacturer have different ratings for the same numbered heaters. For example, an A-B N38 has a different rating that an A-B W38. Different tables are used for heaters in an open starter vs one in an enclosure. Even the type of enclosure can have an effect. Some heaters are relatively [...]
[...] machine, Q is the quarter of the year of manufacture, and V notes variation from the standard model. For example, 52DA2A is a standard (52DA2 A ) single-spindle (52D A 2A) 15" drill press (52 D A2A) that was built in the 2nd quarter (52DA 2 A) of 1952 ( 52 DA2A).

[...] Miller
Another machine made by the same company is shown in Fig. 6. This is a good example of the class of machines which are commonly known as " slab millers." It is now generally conceded that the limiting factor of milling operations is determined by the strength and durability of the cutter. These are greatly extended by having a thoroughly rigid frame and a powerful driving train for the feed of the machine.
There is no class of milling that meets with failure so often as the apparently simple operation of slabbing. The immense [...]
[...] Certain types of loads require motors with high starting torque. A deep-well plunger pump is an example of this type of load. When the water column is high the motor must not only overcome its own inertia but that of the pump mechanism and the water as well. It must really start more than its full load. The same thing may be said of any positive-action pump but not of the centrifugal pump. The centrifugal pump assumes its full load as operating speed is approached. Machines possessing high inertia, like the cream separator, require a high starting [...]

[...] larger amount of nitrogen. Fuels — Different fuels have different heating values. For example, a pound of coal will heat more water than a pound of wood, and a pound of wood more than a pound of straw. The heat value of a fuel is based on the amount of water it will heat and is expressed in what is called heat units. A heat unit is the amount of heat necessary to heat one pound of water through one degree. Measured on this basis, pure carbon would, if all its heat could be utilized, raise 14,650 pounds of water one degree, Fahrenheit. [...]
[...] in the format of serial numbers over the years along with the order that the series occurred. For example, for the Crescent Machine Company, there are five currently known series of serial numbers as follows: The "Crescent" Series. A serial number up to five digits long. Used from the beginning of company until the early 1940's. Example “12345” The "CA-" Series. A serial number up to four digits long prefixed by the letters "CA-". Used after Crescent was sold to Rockwell in the early 1940's. Example: [...]
[...] where friction must be reduced to a minimum, very true hard bearings and journals are used, as for example, the jeweled bearings in watches. In ordinary machinery such bearings would not give good satisfaction for several reasons. They would have to be made perfectly true and would hence be very expensive. They would be more easily broken and more difficult to repair, while with ordinary steel shafting and soft boxes all these difficulties are obviated. A good bearing for farm machinery should be easy to repair or renew in the field at slight expense. It should also [...]
[...] grease gun is all (about 2 teaspoons). Once a year greasing is way more than most applications need. Example, for new motors, Baldor recommends greasing motor bearings every 5,000 hours of operation (3600rpm) or 12,000 hours (1800rpm). At work, a belt driven, 15hp blower motor that runs 24/7 is greased just once a year. Motor has been in service 6+ years now no failure (~48,000 hours of use). I disagree with adding grease until it comes out when greasing a
motor. Bob is right about removing the drain plug but, most (including maint. crew at work) don't bother to remove [...]
[...] understand if the amount of out-of-flat is acceptable in the context of how the machine is to be used.
For example, crowning on a tablesaw top is generally considered to be less of a problem than dishing. Bringing other tolerances in the machine back into spec may do more to improve the machine’s operation than a regrind would. Shims can often be successfully used to slightly raise a ‘droopy’ corner. Lifting up or weighing down a corner to try and ‘spring’ it back into shape can also be tried. Care must be exercised to avoid cracking the cast iron however, and the table may [...]
[...] by Messrs. Fraser & Chalmers of Chicago, and described further on, the engine being a representative example of a modern, triple-expansion engine of the Corliss slow-speed type. The Buckeye triple expansion engine, described in the May number of this magazine, would also be tested as an example of a two-valve engine with a shaft governor. Further, the German engine exhibited by E. Schichau , also previously described, and belonging to the vertical, triple-expansion [...]

These machines were examined by members of His Majesty's Administration, and received official notice and commendation in the House of Commons in 1794. Sir Samuel Bentham was next commissioned to visit different dockyards, and to detemine how far his machines [...]

[...] measure the thickness of the existing shim remains and make new shims of the same thickness out of, for example heavy card stock. It’s not rocket science. Alternatively, try placing the cap back over the bearing. Press down by hand firmly to make good contact against the bearing and measure gap between the bearing
cap and the frame with a feeler gauge. Use shim stock of that measured thickness to make new shims. Remember the bearings don't turn in the babbit, it only holds them in place.
The rest of the disassembly is straightforward and will likely go quickly. Cleanup [...]
[...] rated horsepower gives the actual horsepower the motor could operate at for a short period of time. For example; a 10 HP motor with a SF of 1.15 could actually provide service for a short time up to 11.5 HP. A motor with a high service factor is used on applications where the load may vary and may occasionally be confronted with an unexpected overload in horsepower. Air conditioning systems often use motors with the SF rating of 1.15. The service factor can also be multiplied times the FLA of the motor to give the absolute highest operating amperage the motor should be [...]
[...] of heating the working fluid in their cylinders proper. Compared with the steam engine as a familiar example, and with most hot air engines, we thus find in the gas engine relative simplicity in so far as no separate furnace is necessary in which to burn the fuel from which the energy is primarily derived; furthermore, the energy is available at exactly the moment needed, and there is no storing up of heat in the same sense as in the steam engine and boiler combination. Hence, it will be seen that the gas engine also has a special applicability in all cases where continuous [...]

The Malleable Iron Company is a notable example, He was in fact the life and soul of industrial Marion, and when not directly associated or interested was the inspiring example that gave life to those institutions which have grown up to emphasize the worth of the works he wrought. He had a sincere interest in the welfare of hundreds of workingmen to whom his shops gave employment, and he encouraged and assisted them in getting homes. Every movement for civic good [...]
[...] possibly when the machine was shipped from the factory. Our reasoning for this is that at least one example has shown up where multiple machines which were ordered in a bulk order all were assigned sequential serial numbers. Since the machines were different types of machines which would have most certainly been completed in the factory at different times, it is only logical that serial numbers were assigned as orders were received. Another case, in which we have been able to examine the official Crescent Machine Record, indicates that the serial number was assigned [...]
[...] 1/8 .018 wire that is available from on-line sources such as McMaster-Carr ( www.mcmaster.com, this example was $4.00 plus s/h for a 36" length ). The 1/32 difference in outside diameter (OD) should not matter for purposes of this part. Because the old spring was deformed and stretched, the new first piece that was cut for this project was about 1/2" shorter total length (7.5") than the original spring. After completing the spring (described below) and reassembling the motor, however, the motor was inconsistent on start-up. Sometimes it fired right up, other times [...]
[...] for bearing volatiles and can greatly shorten the life of your bearings by drying up the lube. For example, Oliver 299 type one planers use grease zerks for lubricating the bearings. In this case, it’s unreasonable to have oilers in all those bearings with the bed rollers, section infeed rollers, outfeed rollers etc. On type two machines, Oliver switched to sealed for life bearings. They are expensive and require much more rebuild effort than a zerk greaser or a full bath oiler. Jointers are also a natural for this type of bearing and it works great.

Example: 83B01234 The date code consisted of the two-digit fiscal year of production followed by a letter which designated the month of production according to the following code: A = October G = April B = November H = May C = December I = June D = January J = July E = February K = August F = March L = September This sequence reflected Rockwell's fiscal year of October through September. In the example, the date code (83B) indicated [...]
[...] ends meet, they spent a considerable amount of their time catering to the needs of the community. For example, one account says that much of the work done during the early years was mainly odd jobs– anything from dressing a cross cut saw to making custom iron castings.{Reference:John S. Worman, letter written to Dick Downing on February 13, 1987, regarding the history of the Crescent Machine Company, 1.} To provide extra income in 1896, at the height of the bicycle craze of the day, an ad in the Leetonia Reporter indicates that Crescent was even selling “Stormer” bicycles.{Reference:The [...]
[...] may be present, which builds up a thin film according to the laws governing the flow of fluids. As an example of how this works, when the shaft is still and not rotating, the entire load of the shaft is making contact with the bearing surface. Ideally, at this point, there will be oil in the bearing, which will be surrounding the shaft on either side of the contact point. As the shaft begins to turn, oil from around the bearing will be pulled under the rotating shaft until there is a wedged-shaped film of oil completely around the shaft. If conditions are right and adequate [...]
[...] Fastenings — There are several different ways to fasten the ends of a leather belt together; as for example, lacing, gluing, and by the use of metallic fasteners. All of these methods are in common use and all of them are satisfactory under certain conditions. Lacing is used more widely than any other method, principally for the reason that it is the most convenient and easiest method that we have. There are quite a good many ways of lacing a belt to make a satisfactory fastening. There are, evidently, judging from the appearances of many belts in [...]

[...] tank naturally are done away with, and the engine assumes a somewhat simpler appearance, as shown, for example, in the illustration of the double-cylinder motor. The single cylinder design is followed for sizes up to one horse-power; beyond that, two and four cylinders are employed. In the four-cylinder engines, and also in some of the two-cylinder engines as built in Germany, the cam-groove exhaust valve gear as here described is not used, but in its place a separate cam shaft, driven by gearing from the main shaft is employed. The general features of design and the manner [...]
