Volume Governed Engines

Built in 3, 5, 8, 10, 14, 18 and 25 hp sizes

Volume Governing means regulating the force of the impulse by controlling the amount of each charge. This does not mean reducing or regulating the number of explosions in the cylinder. Where power is wanted for work requiring close speed regulation, constant or custom service, with maximum reliability, the R&V Volume Governing Engines should be sold. This type is unequaled for use in electric lighting plants, machine shops, creameries, cotton gins, custom shelling, grinding or feed cutting.

The "R & V" Horizontal Engine, volume governing, is of the four cycle type, especially designed to meet the requirements of those wanting a strictly high-grade machine. We offer this engine as an exceedingly reliable and durable motor for all power purposes. It is now generally conceded that oil engines in small and medium powers are more economical, convenient, and safer. They require less attention, and in other respects are superior to steam power.

Bed: The bed is of the center crank - box
type, with unusually heavy housings between cylinder and bearings. There are no exposed ribs thus giving a very smooth outline. The top surface of the housings are well above the center line of the engine, thus insuring a very rigid frame. The massive proportions of this bed are shown in the above illustration.
Main Journals: These journals are of the quarter box type, lined with genuine Babbitt,
penned, bored and hand-scraped to size.
The cheeks which receive the thrust are adjustable to compensate for wear, and thus preserve original alignments. The journal caps are notched over the frame, forming a rigid tie between housing and journal support, as clearly shown. Under the journals are cored chambers, which contain the lubricant for automatically oiling the main journals by means of a chain oiler.

Igniter: Of the two forms of ignition in present-day use, the jump spark and make-and-break, we have adopted the make-and break system, as it possesses numerous advantages over the jump spark. It requires no high-tension current, hence is not liable to trouble from short circuits, requires no finely adjusted coil, makes a larger, fatter spark and has proven itself generally more reliable and free from trouble or break-downs than the jump spark. The term "make-and-break" has been applied to this system because when the igniter is tripped, the two electrodes are first brought together inside of the cylinder and make or close the electric circuit. Immediately following, these two points are suddenly drawn apart, breaking the circuit and producing the spark, it being an electrical fact that on closing a circuit there is no spark and upon breaking it a spark is produced. Current is being used only while the electrodes are in contact which is a very short space of time. Hence the igniter is economical in current consumption. The igniter is placed in the center of the cylinder head. All parts are made from drop forgings except the trip, which is of tool steel. The electrodes are of the hammer type, capped with special points that are extremely durable, thus assuring a good, strong spark for over a year's continuous use. The igniter trip is very simple, positive in action, not f liable to get out of order, requires no r delicate adjustment, and is practically noiseless. When desired, a device for advancing the spark is furnished with these engines as an extra.
Volatilizer: During exceptionally cold weather, gasolene will not readily gasify, which under ordinary conditions causes more or less trouble in getting engine to start. To overcome this, we now furnish a volatilizer screwed to the exhaust box cap on all Horizontal Volume Governing Engines of 5hp and larger. In addition we furnish a heater tray attached underneath the inlet air pipe, thus making it possible to start all sizes of engines under any conditions of weather and in all temperatures.

Batteries: We furnish each of our engines with the best and most approved type of battery that the market affords, as so many engine failures are traced to a poor quality battery.

Fittings: These are of the best quality we can buy. All small details of construction receive the most exact and careful attention.

Accessories: One set of Edison-Lalande batteries, consisting of five type"RR" cells with spark coil and switch all substantially boxed, or a magneto. Gasolene tank with pipe and fittings. Muffler, exhaust pipe. Oil can. One monkey wrench and two connecting-rod wrenches. Also an instruction book for setting up. starting and taking care of engine.

Edison Spark Coil

In order to obtain a bright, hot spark, which will unfailingly ignite the explosive mixtures in the combustion chamber, a good spark coil must be used in connection with a battery.

Type "RR" Cell: For stationary engines. Large gas engine model. Capacity 300 ampere-hours. We recommend five of these cells for stationary engines, as it develops a strong, constant current continuously, no attention being necessary until the entire charge is exhausted. They do not waste while idle, are simple in construction. Complete Cell with porcelain jar, $5.80.

Crankshaft.

The crankshaft is turned from a solid steel forging and counter-balanced with weighted discs securely bolted to the webs of the crank, thus counter-weighting the crank and reciprocating parts at the crank rather than in the rim of the balance wheel, as is common gas engine practice. We consider this system of counter-weighting the most correct method as it brings the strains directly on the crank rather than through the shaft, and in high speed work assures a much smoother running engine. The construction of the crank shaft is clearly shown in the illustration.

A group of Horizontal Volume Governed Engines.

This is a later version of the Volume Governing Engine using a detachable water hopper.. It came in hopper or tank cooled.

While this style of engine is higher in price than the Triumph and similar engines, the volume governing engines is practically in a class by itself and possesses a distinct individuality because few manufacturers of engines make anything of the kind.


As found

The finished job

This particular engine, above, uses a high tension magneto (Bosch) and spark plug, possibly used on export models for better reliability away from the ready availability of factory spare parts. The USA version, from factory photographs, show low tension ignitor and battery setup, although a magneto is mentioned. Batteries of the day, made with glass cases, would have been fragile to transport overseas.
