UAR'fSPRING.

To ALL WHoM Ir MAY coNcERN:

Be it known that I, WILLIAM F. RAY, of Fort Wayne, in the county of Allen, and State of Indiana, have invented certain new and useful Improvements` in Engine, Car, and Carriage-Springs, or for other purposes; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. In the drawingsi Y Figure 1 is a side elevation.

Figure 2 is a plan view sectioned in line ma', iig. 1.

The nature of my invention consists in the arrangement and constructiouof metallic springs for cars, Snc., ttc., which, although light and exceedingly elastic, possesspgreatstrength' and resistance. By the peculiar arrangement and combination ofthe parts the springs maybe so adjusted that the power'or resistance may4 lbe increased or decreased to an'almost unlimited extent.

To enable others skilled'in the arts to make and use my invention,`I willrclescribe its construction and loperation.

A represents metallic bars, of a suitable length, width, and thickness. 'These bars are bent at intervals alternately in opposite directions, as seen in iig. 1, so that the curve of each bend forms a semicircle. The straightV portion of the bars which extend from curve to curve, run parallel and fit snugly together. 'As many bonds as the requirements of the case may justify may be melde. B B `represent clamps, which are constructed in the manner shon'n in the drawings, and are adjusted to the respective ends of the springs, in such a manner as to secure them in position. These clamps may be either secured by means of boltsor otherwise. C C represent stops, which may be made of metal or other material. They are so construetedthat they'till or lit into the space formed by the'bending ot the springs. It will be observed that, as the bars 'are of equal length whenV they are bent, the outside bar falls short of extending to the same point reached bythe inside bar; hence the necessity of the use of stops C C. -fllieir particular-functions are to give a permanent bearing to the end of the respective hars, and thus enable them more effectually to counteract the resistance and necessary vibrations to which they are constantly submitted. The stopsA C G may be made of any length to suit any desired adjustment of the spring. It will be readily understood that springs made-inv this 4form maybe easily adjusted bysliding the respective bars out, as seen infig. l, or in, so thattbsir curved portions come in direct contact. The effect of this adjustment is, in the latter case, to render the spring much less capable of resistance, thus adapting it to lighter Weights without in the least changing its ilexibility or'elastici'ty, while in the first case'the strength or power of resistance .is increased just in proportion t-o'- the distance they are, separated, without in the least impairrng their elasticity, thus, by a new adjustment, easily effected, adapting this spring to the contingency of the case. I use one or more bars in the construction of these springs, which may be dat, round, square, tubular, oval, or in any other form. i I also use those-me Vspring with or without packing of rubber, or cork, or other elastic substance. Said packingto be inserted between the folds of the springs in such u. manner as to add strength or elasticity to the same.

What I claim as new, and desire to secure by Letters Patent, is- A series of reiiexed springs, so constructed that the bows slide into each other, the VWhole being adjustable so as to regulate .the amount of elasticity, as described.
