a T14E MIC1416AN -DAILY' Engineering Department Gets New Chalmers High-speed Moto ENGINEERHS TO GET CHALMERHS MOTOR Department Secures Machine Through Efforts of Men on Company's Selling Division The bill of lading has just been re- ceived by the Automobile Engineering Department from the Chalmers Motor Car Company of Detroit for one of their latest complete motors, model 35. This presentation to the depart- ment has been made through the ef- forts of Mr. Malcolm McCormick and Mr. Paul Smith, Vice-President of the selling division of the Chalmers. The motor is the same as the one used in their master six, running at 3400 R. P. M. and delivering 35 horse- power at 2400 R. P. M. It is the first extremely high speed motor presented to the laboratory and will thus make a very valuable addition to the al- ready complete laboratory equipment. The remarkable co-operation of au- tomobile manufacturers with the de- partment is well indicated by the fact -that equipment has been presented for use in laboratory courses by the fol- lowing :automobile manufacturers: Studebaker--Complete show chassis and engine section to show interior. Cadillac -1916 8-cylinder motor WORTH WHILE FACS OF MOTORINGWORLD A recent article in Popular Mechan- ics exploits the invention of an electric windshield cleaner. A coil of wire, oval in shape, and perhaps six or eight inches in the largest inside di- mension, is clamped against the glass of the windshield by means of springs attached to the frame. Current from a storage battery is sent through the coil, the latter having enough resis- tance to produce considerable heat. This heat is said to be sufficient to melt frost and snow from the shield, thus permitting a clear view ahead under the most adverse conditions. ---o- EELEPHONE LINE FOR SAFETY On a steep winding grade near Hood River, Oregon, where the road is too narrow to permit the passing of two automobiles, a telephone line has been installed to enable the motorist to as- certain whether or not the road is clear. Before the system was installed there were frequent tie-ups caused by the meeting of two cars on the hill, which invariably caused the up-bound machine to back down the perilous grade. ---0------ DESIGN AUTO LIGHT DIFFUSER A light diffuser designed to be car- ried on the windshield of an automo- bile is the latest means of counteract- ing the glare from the headlight of an approaching car, as Al as pre- venting the eye strain caused by the glare of the sunlight on the roadway. The device consists of a square of special amber glass mounted in a framework of brass rods, and so ar- ranged that the glass can be placed in any position to suit the line of vision of the driver. CLASSIFY ALL ROAD SURFACES It is not generally known how many different kinds of road surfaces there are in use in this country. The Unit- ed States department of agriculture has classified them under the fol- lowing heads: Brick paved, concrete, (Continued on Page Seven) The Question of Horse Power and Cir Fe(lonly 'akei . Up by Two Comitt ees IIMPOlITA NT TO BUYI N PUITA( 'Iw o unusually important question w from the standpoint of the automobile buying public, are now being consid- ered by two committees of the.Soci- ety of Automobile Engineers, on both of which Prof. w. T. PFishleigh is a member. The Engine and Transmission divi- sion, organized for the consideration of all questions of design and stan- dardization of the motor, transmission, clutch, and rear azle units, has un- dertaken the collection and interpreta- tion of motor characteristic curves, and in connection with this work has given much consideration to the ques- tion of Horse Power rating. At the present time many manufacturers rate their mtors by the so-called A. L. A. M. or S. A. E. formula: Horse Power NoI bore x bore x number of cylinders divided by 2.5. This formula gives an approximate value of the horse power of amotor at 1,000 feet per minute piston speed, which for a motor of 6-inch stroke would be at 1,000 R. P. M. It thus appears that for a motor, this formu- la gives the approximate maximum horse power output at a motor speed which is not far from average road operating speeds. While this figure is important and desirable, the maximum horse power output of a motor at high speed is also of great interest and importance to both engineer and operator. Some manufacturers, indeed, neglect the S. A. E. rating entirely and proceed to rate their motors by this maximum figure. 'thus it is that the engineer and the prospective automobile owner is' confronted with a most disconcert- ing mix-up in rating which makes a reliable comparative study difficult, if not impossible. The public and the automobile en- gineer is taking a decided interest in this matter. All recognize that the present state of affairs is far from satisfactory. In this connection, Pro- fessor Fishleigh, as chairman of the Engine and Transmission committee, has suggested a simple, yet adequate (Continued on Page Eight) silET-Up IOR i)ETEIMI N INi' E I.R( G )I lI5tT 1.

TESTS SHOW LOSS OF ENERGY W. H. FAUST, 1421 Hill St. The automobile squad is at present engaged in determining by the most refined laboratory methods just what becomes of the energy which is fur- nished to the motor in the gasoline. Although several investigators have accounted for causes responsible for a small portion of the total energy used up, no tests as com- plete as those carried out by the local squad have as yet been undertaken by anyone.- 1 The energy furnished the motor is partially re- covered in ubrake horse power, while the remain- der is consumed by fric- tional horse power, ex- haust, cooling water, and some energy, in the form r of heat, is carried by the air draft past the motor. The squad is actu- ally measuring all these quantities, and from the results of their tests they are determining a complete heat balance. The tests have been carried out on a very elaborate setup, the only one of its kind in the country. The preliminary runs have just been completed and indications point to an accuracy of 95 to 97%, a remarkable figure for automobile work of this magnitude. Approximate figures for two preliminary runs, the first with motor developing 4.5 horse power, the second developing 16 horse power, both at 640 R. P. M., are as follows. The motor tested is a Hudson six-54.

Car-Body Srings Need Care Many motorists do not give the attention to the car-body springs necessary to keep them in good condition. These springs need oil the same as any other bearing on the car. Many cheap devices are on the market for opening the springs so that oil or graphite can be inserted. This attention should be given at least every six months if the car is used regularly.
