UNITED STATES PATENT OFFICE.
CHARLES COPPIN HEARLE, OF MONTREAL, QUEBEC, CANADA.
SPRING.
' JEEGIFICATION forming part of Letters Patent No. 338,267, dated March 23, 1886.
Application filed October 19, 1885. Serial No. 180,382.
To @ZZ whom it may concern:
' Be it known that I, CHARLES CoPrIN HEARLE, a subject of the Queen of Great Britain, and a resident of Montreal, in the district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Springs; and I do hereby declare that the following is a full, clear, and exact description thereof.
The object of my invention is to produce a spiral spring which is so constructed that it will carry with elasticity either alight or heavy load, and that it will withstand the requisite amount of resistance, thus accommodating itself to any given weight that may be placed upon it and at the same time retain its elasticity.
Referring to the drawings, Figure l is a front viewofmyimproved spiral spring. Fig. 2 is a sectional view of the same. Fig. 3 is a plan view of the rod or bar of steel or other metal before rolled up into a spiral spring, as shown in Fig. 1.
Similarletters referto similar parts throughout the several views.
A is a rod or bar of steel or other metal, and which can bc made round, square, or of any other shape, and of any desired length necessary to make any required size of coil. rlhis bar or rod of metal is made thick and straight from a to b. From b toc it is tapered and made gradually thinner. From c to d it is straight and thin. Vhen the spiral spring is formed out of the rod or bar A, the part from a to b forms the lower coils. The part from Z to c (No model.) Patented in Canalla November 26, 1885, No. 22,885.
forms the threeother coils, and the part from c to d forms the upper coils.
Although I show this mode of constructing the coil, I am aware the same result may be accomplished by forming the coil with the heavy part on top and the thin at the bottom.
Vith a light load or empty car or Vehicle the thinner metal of the spiral spring carries the weight. As the load increases, these coils become compressed. Then these coils are compressed or closed downward or upward, or vice versa, no further or greater strain comes on them. The load then presses down or up the tapered part unt-il it is also closed down or raised, and the heavier part of the spring carries the maximum load. I can by this construction make a spring which will be elastic under all conditions up to its full capacity.
The spring constructed as described may be used on railroad-cars, vehicles, and for lany other purposes where springs are required.
Having thus described my invention, I desire to claim- A spiral spring formed out of a bar or rod of iron or steel or other metal, A, which is straight and thick from a to b, tapered and thin from b to c, and thin and straight from c to d, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand.
CHARLES COPPIN HEARLE.
