CAR SPRING.
N0.95,49'7. Patented Oct-5,1869, I
itluitul tstes pawl can,
Letters Patent N 95,497, dated October 5,1869;
mmov'nn CAR-SPRING.
. The Schedule rezoned to in these Letters Patent and making part of the lame.
To all whom it may concern:
Be it known that I, JAMES R. Mlvrnnws, of the town and county of New ,London, State of Connecticut, have invented a new and useful Improvement in Gar-Springs; and I do hereby declare that the'following is a fnll,'clear, and exactdescription of the same, reference bein g had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a vertical half plan and section.
Figure 2 is a horizontal 'plan,with hall of first plate rcmoveih Like letters refer to like parts.
M y invention relates to that class of springs in which corrugated metal'sprin'gs are used, and consists of a combination of plain andicorrugated plates, arranged and formed as hereinafter described.
inthe accompanying drawings- A A A" represent any number of plain, flat, circular. plates. Between these are interposed radiallyeorrugated plates, B B B the corrugates being formed so that their top and bottom surfaces of contaet are parallel with each other, or so that the entire length of the --corrugate is in contact with the interposed plain plate A.
These plates are held from turning by the projection D, in a groove formed in the bolt 0. The plain plates are allowed to turn freely on the bolt 0.
The spring is formed by a bolt, 0, provided with a groove or.key- -ivay. On this bolt is placed, first, a
'B",having their top and bottom surfaces of contact a corrugated plate, B, next, 2. until the spring reaches the being plain plate, A, next, plain plate A, and so on, required thickness, the top of one-cormgate immediately under the one 'above it, as shown.
I am awarethat springs have been made with cormgated plates, and that the-same are of various forms, and-that India rubber has been interposed between them. v I do not claimany of these features, but rest my claim on the formation of the conngates, so as to render their use, in combination with plain plates,
practicable, my invention requiring. the use of corrugated plates, in which the top andbottom surfaces of contact are parallel, and remain 'so throughout the entire period of compression, and having a plain plate interposed to allow each spring to act iudependently/sf of the others. Having thus described my invention,
What I claim, is
A spring, formed of radially-corrugated plates B B parallel to each other, and arranged alternately with plain, flat plates A A A*, substantially as herein described.
' JAMES R. MATHEWS.
