To ALL WHoM IT MAY GONCERN: y 4 n Beit known that -I, JOHN BARRON, of Cincinnati, inthe county-of Hamilton, and `State of Ohio, have linvented. an Improved Rocker for .Chair-s, Cribs,` RockingHorses, Sto.; and I do hereby declare that thefollowy t y n ing is a' full andexact description thereof, reference being had to the accompanying drawings, making part of M this specification-L- L i u Iligure` 1 being a side view of a rockerprovidedwith my improvement. t Figure 2, a central longitudinal vertical section thereof.f

Figure 3, a transverse vertical section of the same. l -V Like letters designate corresponding parts' in all of the figures.

I make an elastic rocker. The `elastic bottom B is of India rubbeigaudis constructed and applied to the i l rocker A substantially as follows:

vI takea piece of India-rubber'tub'eor pipe,ias`in ligs. 1, 2, and 3, ofthe properlength and diameter, and `l j l it `it in a. curved 'or nearlysemicircular groove, foi-.med longitudinallyin` thebottoui'ot`` the rocker, substantially i n as indicated in lig. 3. To secure this tubev to the rocker, a Wire, C,'ispassed `through it, the endsof'the wire y being extended beyond the tube, and through" caps a a fitted and fastened over the ends of tlievrocker. Screpvthreads areformed upon the ends of the-wire, so as to secure itin place by mits b Ab. -:By tightening these nuts the tube B can be drawn tightly and firmly intothe groove of the rocker, and, 'by unserewing thenuts, the tube ,n

isfreadily removed or replaced. i l Y y Any equivalent 'of the wire C maybe used, and any other suitable or convenient arrangement for fasten-lf ing may' be adopted. The peculiar yielding, ,but suciently firm elastcity,`prodi 1ced by the tube Bis superior, n i i and very'desirable for the purposes indicated, or for anyv analogous use.

Whatl claim as my invention, and desire to `secure'by Letters Patent, is- The employment of elastic tubes or pipes, in combination with chair and other rockers, substantially as and for the purpose herein specified.V 1 y The above specification of my improved elastic rockers for chairs, cribs, roekngfhorses, 8vo., signed by me t JOHN ,BARRON Witnesses:
