TO WHOM IT MAY CONCERN:

Beit known that I, DAVID COX, of- Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Cradles; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

The rst part of my invention relates to rocking devices.' The second part of my invention relates to an improved folding tester. I i

Figure 1 is a perspective view of a cradle embodying my improvements. i

Figure 2 is a transverse section thereof.

Figure 3 shows the body ofl the cradle turned upside dowir.

The body A has two customary rockers B B', which both rest upon and are confined to the convcxheads c c of the two stands or tres'tles- C C united iu one 4frame by two rails -D D. In order to soften the action and deaden sound, the convex surface of each rocker and trestle is padded with a strip, E E", c e', of leather caoutchouc, or other suitable cushion, and is further provided with two bands or straps, F F', fj", of steel, which, being attached by one extremity to a rocker, and the other extremity to thet'urther end of its supporting trestle, prevent any displacement of the body, while allowing it to rock freely from side to side, and cvenassisting said rocking by its elasticity. The rocking is eil'ected by means of a treadle, G, pvoted, y, to one ot' the trestles,

and having hinged to it a rod, H, whose sum-nit has a cushion of caoutchouc, or other suitable substance, and, A

by impinging against one of the rochers, sets the body in motion.4 It will be seen that, in order to enable the body to be niade rigid, I have provided a bar, I, which, being joui-nailed, z', at its mid-length to the rail D, is

susceptible of being turned so as to extend athwart the frame, with its ends supporting the respective sides of.,

the body, and el'eetually stop auf,I oscillation of the latter. J are stops, which limit thevibration of the bar I in both directions. Inclined planes K K abilitate the turningof the' bar and prevent. it catching against the longitudinal portions of `the body. In its inost complete form the body has .hinged to its respective endsv brackets L L', having pivoted lo their free ends hars M M,'a dowel m, on one of which enters n. sock'en l, in the other. The two bars thus engaged are made fast by means of a hook, N, and staple n. When not required for use, the two members of "iiiis tester may he folded down snugly outside of the body, shown by dotted lines in fig. 1, and by strong lines in iig. 3. A marked advantage of the above overthe common form ot' rocker isl found in the non-liability to shift and slip about the iloor inthe action of rocking. O O are blocks, placed at the ends of the upper rail-D', so :1s .to prevent the longitudinal displacement of the cradle-body; and l" is'a cushion or pad attached to the 'treadleg and said cushion rests upon astud, which projects from the inner side of one of the trestles C. VThis arrangement otl the eushond prevents any noise when the treadle is dropped.

I claim as new, and of my inrentionv I. The combination of the cushions Ec with the rockers B u and 'straps l" j', as and for' the purposes explained.

2. The combination ofthe treadle G and cushioned rod H h with the cradle A B and convex rocking surfacesE, substantially' as and for the purposes speciiied. v

3. The combination of the turn-bar I, cradle A B, and trestleC D E, as and for the purposes specitied.

4. The combination of the inclined planes K K with the turn-bar-I, cradle A-B, and supporting trestlc C D E, for thepurpose described.

In testimony ot' which invention I hereunto set my\hand.

DAVID COX. i
