IMPROVED DBVIGE FOR PREPARING PLATES FOR SPRINGS.

TO ALL WHOM IT MAY CONCERN:
Be it known that I, JAMES B. CLEVELAND, of Hackensaek, in the county of Bergen, and State of New Jersey, have invented a new and improved Device for Preparing Spring-Pletes, and that the following description, taken inconnection with the nccompanying drawings, hereinafter refet-red to, forms a, full and exact specication of the same, wherein I have set ferth the nature and principlcs of my said improvements, by which my invention may be distinguished from all others of a similarclass, together with such parte as I claim, and desire to have secured to me by Letters Patent. i
.This invention relates to a new and improved devce for preparing pl'ates for vehicle and other springs.
The object of the invention is to avoid the labor now necessarily expended in rendering the plates smooth, or giving them :n even or true surface, work now performed by means of a grindstone.
The invention consist in subjectng the plates, previous to the operation of rolling, to the action of dies, whercby they are reduced to the proper thickuess throughout their entire length, and consequently will admit of bcing roilcd perfectly smooth and true. In the accompanying sheet of drawings Figure 1 is' a side sectional view of my invention, taken in the line x x, fig. 2.
Figure 2', a front view of the same.

A A' rep resent two rollers which are placed one above the other in the same axial plane, and have their bearings in standards B B. On one of the journals of the lower roller A' there is keyed a wheel, C, having a pin, a, projeeting from it et some distance from its centre, and fitting inan oblong slot, b, in one end ofe lever, D, the fulcrum-pin c of which passes through u block, E, on the base F of the dcvice, (see fig. 1.) The pin a of the wheel C, fitting in the oblong 'slot b, operates the lever D when the machine is at work, and to the front end of lever D there is Secured a die-block, G, having two dies, c e', made in it, of the shape, but of diiferent sizes, to suit difi`erent-sized plates. These dies e c' are directly over similar but fixed dies, d d', which are secured on the base F. All of these dies are simply grooves having parellel sides and a curved bottom, the latter being designeted by the dotted lines in fig. 1, the curved bottoms corresponding to the form designed for the eurved sidcs of the plates from their centi-es; outwa-rd to their ends. These dies perform a. very important function, as
they reduce the plates to he rolled to the proper thickness required, and give them the desired width and curveture at their sides. The plates are properly heted and placed in the lower died or d', and when the upper die e or c' is forced down by the operation of the lever D, the plote (one-half) will be compressed between the upper and lowcr'die and brought to a uniform width. The plate is reversed, the other halfplaced in the lower dic while the upper one is rising, and when the upper die descends is subjccted to a. like action. The plate is then rolled out even and true by the rollers A A', iu consequence of this previous swaging'between the dies. I
Having thus described my invention, I claim as new, end desire to secureby Letters Patent- The combination of the' dies C C', hlocks G, fixed dies dd in the block E, slotted lever D, wheel C, and r'ollers A A, as herein set forth for the purpose specified. i
The above specificetion of my invention signed by me this 18th day of May, 1867.
