Show b THE MODERN AUTOMOBILE By George Bcrgstrom, Instructor Auto-Mechanics. Ogden High Schoul. Written especially for The Standard Kxuiuiner. s : win i LA I The wheels, a very Important part of automobile construction, have had considerable attention from the manufacturers man-ufacturers of mod.-rn automobiles-iThese automobiles-iThese once were divided Into two i clashes, pleasure cars and trucks. Iatc-ly Iatc-ly they have been ilividej into further i divisions wood, wire, sheet stecK I pressed steel, dlSC, and spring wheels. These wheels used In combination I with tires, makes a cushion or a yielding yield-ing contact with the surface of tho Irond, assuring ease and comfort for those riding In the car. It is obvious that the larger the wheel the cafh-r 'riding the car. because of Its greater , surface In passing over objects In tho road or over ruts and depressions. Still tho tendency Is to decrease the !siz of the wheel and make the tires 'larger 'n circumference. I ! i -1 I ; t CAR W 1 1 1 i I -It used to be that the wood wheel 'was almost universal In this country I for pleasure cars Now we can get wire wheels for nearly any car that Is sold on the market Wonden wheels are usually made In the artillery typ. Iwlth an even number of spokes which I are tapered at the hub end, rounded Op with a small t ml that fits In the 'felloe The tapered or the wedge end I usually fits into the hub through which I Is placed a number f bolls which are ! drawn up tight so as to make the In-'i.er In-'i.er part of the wheel rigid. There are four distinct parts to the wheel: tho hub. Into which fits the beantngl axles or spindles; the spokes, which connect the hub and felloe: the felloe, which holds .n the fuel rlrn. an.l the rim. on which is mounted the tiro with Its rim. It is necessary sometimes some-times to tighten the spokes by driving wedtfes betWM n them where the spokes go into the hub. These may also have ; to be changed according to the w ear or the looseness of the wheel WIR1 w in. I L8, Many parts of th automobile were taken from the bicycle Wire wheels are one. M ID1 i; 1T The first type of wire wheel that came Into use In America was not successful suc-cessful because It did not have very many good points about It, practically practical-ly nothing but Its lightweight. Tho spokeg were set Into a casting which formed the hub and had adjustable ! nipples which came through the steel. The spokes were kept tight by these : threaded sleeves; In fact. o tight that the wheels were not capable of taking or receiving any side stresses Then camj a rapid change back to the wooden wheels, but the manufacturers i knew their faults and weaknesses and set out from a different viewpoint to make wire wheels England and' France were the first to adopt them I and make them successful. This was! done by doing away with the cast hub. I and making another of drawn or pressed press-ed sie.-i .if a high grade- Lighter spokes and more of them, which make the wire wheels lighter In weight, and-stronger and-stronger in construction, lower first! cost and superior strength In direction at rlRht angles to the plane of the wheels. Tho nw successful design of wlre( wheels have double and triple spokes. On the heavier cars thry use a quadruple quad-ruple type. The additional row of . 'spokes In the triple type acts as a slrengthenor and stlffener like the diagonal di-agonal stavs on a bridge These wheels are much stronger than the former type of wheel. Greater attention has been paid to the manufacture, assembly assem-bly and use Since 1914 they have gained In popularity, so much so that (now you can purchase them for nearly j every car made H 1 1 E i t m EI i WHBBLS. This Is really another form of the wire spoke wheel, except that an in-Iflnlte in-Iflnlte number of spokes are Joined to-igether. to-igether. It has strength, low cost, lightness and . 1 -anllness. There Is Htrengih In the triangular form of the sheet steel plates, an unusually strong connection at the top and bottom Is similar to a box girder, having great resisting, strength In all directions, its I low cost is brought about by Its slm-ipllclty slm-ipllclty and little machine work nenes-.s-ary. Its rigidity of construction and few parts, its lightness comes from the thin steel plates and the thin connecting con-necting members. Tho felloe Is done i.iwav with, and many other parts are simplified, its cleanliness Is apparent for all that is necessary Is to turn the hose on the outside for there Is no place for the dirt to collect.
