5th to 22nd July, 1911. Open to the World, at Winnipeg.
The following rules and conditions will be strictly adhered to :
CLASSIFICATION.
1. The entries shall be classified as follows : (a) Gasoline engines whose piston displacement is 300 cubic ft. per minute and under. (b) Gasoline engines whose piston displacement is over 300 and under 500 cubic ft. per minute. (c) Gasoline engines whose piston displacement is 500 'cubic ft. per minute and over.
(d) Kerosene engines, all sizes.
(The piston displacement to be calculated on a basis of a piston speed of 700 ft. per minute and to be equal to the total piston area in square ft. multiplied by 700.) Where A -= Piston area in sq. ft. P = Boiler pressure and 450 is taken as a standard speed. A x 450 X P
(e) = 60 or under. 500 A x 450 x P (f) over 60 and under 100. 500 A x 450 X P
(g) 100 or over.
500 Prizes shall consist of :-1st prize, gold medal ; 2nd prize, silver medal ; 3rd prize, bronze medal.
ENTRIES.
2. All entries must be made on or before 1st. June, 1911, and must be made on the official entry form, with all data filled in accurately and accompanied with an entry fee of $25.00 for each entry.
All entries must be accompanied by an affidavit that the information therein is true and that the engine in question is from their regular stock, not being built, specially for competition. A blue print, or photograph of blue print, of the boiler, with the approval stamp of the Alberta inspector thereon, must also accompany the entry.
Each entry shall be allotted an official number, which shall be displayed during the competition. 3. Any firm or individual shall not enter more than. one engine in each class unless the engines be radically different in construction.
In all classes where there is no 'competition a. diploma of award only may be given, upon which will be set forth, together with the number of points scored, that it was the only entry in the class.
Should the judges find the entry data inaccurate in any particular, they may at their discretion rule the engine out of the contest.
CONDITIONS.
4. The fuel shall be that furnished by the Exhibition. Association at current prices at Winnipeg, 'approximately :— Gasoline 20c per gallon of 277 cubic in.
Kerosene ... 12c. )7 • 71 !I
Soft coal ... $8.50 per ton of 2,000 lb.
Wood I.50 per Cord.
5. Each competitor must have sufficient staff for the' care and running of his Own entry. Two men only, except observers, will be allowed on the steam engines during a test ; one an engineer and one a fireman.
Two men will be allowed to start the internal-combustion engines ; after starting, one man only, except observers, will be permitted on the engine. If more men are needed the engine will be penalized 10 points for each man.
No other petson to be allowed near the engine.
The names of the operators to be furnished the judges at commencement, of test, and the same operators to handle the engines during all tests. One man only will be allowed on the ploughs.
6. All motors must be on the grounds not later than 5th July, 1911.
7. Each motor shall be allotted a certain space on the grounds, where the motors shall be exhibited at all times except when being tested.
TESTS.
8. Test to comprise brake test, ploughing test, and such other tests as the judges deem essential.
9. The ploughs, belts, chains, water-tanks, a. two
hour recording dynamometer of capacity sufficient for their engines, with sufficient charts and such other things as may be required during the tests, must be supplied by the contestants.
10. The judges may test the engines in any order that may to them seem desirable. The contestants will be given one hour's notice when to be ready.
11. The rules of the Province of Alberta with regard to boilers and engines shan govern the pressures, etc. 12. All instruments, including dynamometers, shall be deposited with the judges on the arrival of the engines on the exhibition grounds, for testing, and shall remain in their possession until all tests are completed.
Provision shall be made so that a standard steam gauge can be applied to all boilers during the test.
13. Any engine failing to complete any test shall be disqualified. 14. Contestants shall be prepared to assist the judges and their observers in taking dimensions, removing parts for inspection, etc.
15. Each competitor is asked to appoint one observer, whose duty shall be to check the fuel, water and other data taken by the official observers.
No observer will be appointed to check the data taken on the engine entered by the firm he represents,
but will be chosen by lot to check the data on other engines. His duties will be merely to ascertain that the data is correct and to certify to that effect by his signature on the official observer's card.
16. The brake test shall consist of a two-hour economy test. During this test the engines are to run at their greatest load consistent with economy. Competitors will be allowed 15 minutes after they have lined up to the brake to try out their engines, and to state the amount of load they wish to carry. After the competitor has stated the load he wishes to carry, the operators will keep the brake as near that load as possible for two hours, and no change will be made. Careful measurements of the fuel and water used will be taken, and the condition of the engine noted. Also the mean effective pressure developed in the cylinder will also be taken into account.
After the two hours' run a test will be made of the maximum horse-power the engine will develop for 30 min. ; careful measurements again being taken of all the fuel and water.
Ploughing test shall extend over a period of five hours or longer, if deemed necessary by the judges. The contestants may use any kind of plough they wish.
The depth of ploughing to be uniform, and as directed by the judges. A recording dynamometer will be placed between the engine and the plough, which will accurately record the pull. Careful measurements will be taken of the fuel and water used ; the acres
ploughed ; the drawbar pull ; the fuel per acre ; the distance travelled without replenishing, and such other data as the judges deem essential. At least one two-hour chart must be made by each engine.
DESIGN AND CONSTRUCTION.
Under this head will be considered the protection of the working parts from mud and dust ; dust-proof hearings; accessibility of all parts, such as valves, igniters, bearings, fuel and water tanks ; facilities for washing out the boiler ; cleaning grates and tubes ; ease of manipulation, such as starting and stopping, reversing and the general handling of the engine ; the clearance of working parts from the ground ; the proportion of the various working parts of the machine and the materials of construction, etc.
GENERAL.
It is to be expressly understood and agreed by the manufacturer that the engines entered in the competition are of the same material and construction as those he is selling in the open market. Only such pressures andspeeds will be allowed during the tests as are used under ordinary working conditions. The judges may limit the speed or pressure of any engine when they deem it necessary to a fair test. Contestants must submit their dynamometer, steam gauges, etc., to such tests as the judges deem necessary to assure them of their accuracy.
The competitors, upon being given notice of the testing of their engines, are to make all arrangements for water, belts, etc., so that as little delay as possible will result.
The following are points upon which the awards will be made :-
