TO ALL WHOM IT MAY CONCERN;
Be it known that I, IRA N. BEVANS, of Terryville, in the county of Litchfield, and State of Connecticut, have invented a new and useful Improvement in Apparatus for Tempering Steel Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1 represents a longitudinal vertical section of this invention, taken in the plane indicated by the iine a: :v, fig. 2.
Figure 2 is a plan or top view of the same.
Similar letters of reference indicate like parts.
This invention relates to an apparatus in which steel springs are tempered by drawing-them through a vessel containing melted lead. In ordinary apparatus of this kind the spring on leaving this vessel is wound on a drum which receives a positive revolving motion by gear-Wheels or-belts, and as the spring Winds on this drum it is drawn through the melted lead. By this operation the operation of tempering the springs is not uniform, because the diameter of the drum increases and the spring is drawn through the lead quicker and quicker, so that it becomes too soft at the beginning and remains too hard at the end of the operation. This difiiculty is obviated by this present improvement, which consists in the arrangement of two feed-rollers in combination with the vessel containing the melted lead, in such a manner that by said feed-rollers the spring is drawn through the melted lead with uniform velocity, the reversing-drum being driven by friction or other indirect means, so that ittakes up what is delivered by the feed-rollers and not more, and the temper of the spring is drawn uniform from beginning to end.
A represents a vessel containing melted lead or other suitable material by which the temper can be drawn from a steel spring. The spring is taken .i'rom the drum B and passed through the vesseLA by the action of the feed-rollers C, which clamp the same tight and cause it to travel with uniform velocity. After leaving-the feed-rollers the spring is wound upon the drum D, which is revolved by friction or other indirect means so that it takes up what is delivered by the feed-rollers and not more. By this means a spring of uniform hardness is obtained.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent-- The feed-rollers C, in combination with the vessel A'and receiving-drum D, substantially as and for the purpose set forth.
The above specification of my invention signed by me this 2d day of February, 1866.
' IRA N. BEVANS.
