.Let-ters Patent No. 97,705, dated December 7, 1869.
I IMPROVE!) COIL-SPRING- AN'D ITS ATTACHMENTS.
The Schedule referred to in these' Letters Patent and making part of the same.
l 'We, TIMOTHY Rosa, of Cortland, Cortland county, .in the State of N ew York, and PLATT S. BUEILL, ot' `Windsor,'in the county of Broome, `and State aforesaid, have invented certain Improvements in Coil- Springs and iheir Attachments, of which the following is a specification.
The nature and objects of our` invention are to provide a coil-sprin g forbeds, car and wagon-seats, chairs,
and the like, which, in a given'space, will give/more elasticity than the ordinary coil-spring, and is combined with a cavity underneath the spring in the form of a concave, into which the spring may be pressed,
the successive coils resting upon the concave vwhen pressed down. 4
The accompanying drawing represents a perspective view o f the spring and attachments.
-The wire is coiled upon a form, the llower part, say for one-half the height of the spring, is made conical,
4andthe upper half or portion is cylindrical, as shown in the drawings `by the parts `marked A and B, respectively.
The spring is then placed upon a block or other base, F, which 4is hollowed out beneath the spring, iu the form of a concave, G O, corresponding in size to the `conical port-ionhof the coil, but' the depth of the con'- cave is not quite equal tothe height of the conical portion of the coil.
In the cylindrical part of vthe coil is inserted, from the top, a movable plug or standard, I, reaching down` to the conical portion of the spring, or nearly so,
This standard may have a button, D, or flange upon the top, projecting over the wire lto prevent the plug working down, and also-furnishing a base for the support of any weight, and to which to attach slats, canvas, or webbing. ,l p
At 4the bottom of the concavel is a hole, through which the lower end of the plug or standard may pass when the spring is pressed down.
The operation ofi-his spring land. attachments is as follows:
As the spring is pressed down, its differentA coils` in its conical portion successively come into the concave, and rest upon its sides, and when the last coil of such conicalportio'n `comes toits rest in the concave, there -is then left, and in use, the cylindricalportion of the spring, its base resting upon lthe lower portion of the concave.
As the conical part of the spring has the larger diameter, it will, of course, be the more elastic, and will be pressed down 4into the concave beneath, before the cylindrical portion is much compressed, `the strongest part of the spring is thus used last. l
\ What we claim, andv desire to secure by Letters Patent, isf- 1. The coil-spring A B, in the form described, that is, with the lower part in a conical form, and the upper part in a'cylindrical form, for the uses and purposes setforth.
2. The combination of a conical coil-spring, (whether with or without thecylindrical part,)witl 1 the concave l depression underneath said spring, when made in the manner described, fonthe uses and purposes set forth.
3. The combination of the spxingAB, the concave depression GC, andL the plug or standard I, for the uses and purposes described.
In testimony whereof, we have signed our names to `this specification, in the presence of two subscribing witnesses. i
