shock or jar is transmitted to the occupant of the cradle.
These and other objects, which will become more fully apparent as the description progresses, are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure l is an end elevational view showing a cradle made in accordance with the invention, parts being removed so as to disclose the construction.

view taken on line 55 of Fig. 1.
Referring to the drawings in-detail, the
Mounted in each of the bars 15 are vertical sleeves 23, and slidably engaged therein are plungers 24, encircled at their upper ends by coiled compression springs 25, the plunger being provided with extending heads 26, contactable with outstanding lugs 27, secured upon the ends 18 of the cradle,
near its edges, by which the plungers may be depressed.-
Formed in the lower ends of the plungers 24 are forks 28 in which, carried by the pins 23, are slotted levers 30, these levers being pivoted to swing freely in the projections 31, the same extending down from the terminals of the arcuate elements 16, the inner ends of the levers 30, being formed into hooks 32, adapted to engage with projections 33, extending from each end of a guard-like element 34, fixed upon a pinion 35, mounted upon a spindle 36, supported by a bar 37,
having bracket like feet 38, fixed to the inner surface of the end walls '12. The teeth of the pinion 35 are engaged with the teeth of a spur gear 39, rigidly secured upon the spindles 17, which support the cradle body on the arcuate elements, the springs '25 being depressed by the bumper. lugs 27 and the levers'30 caused to make yielding but forcible contact with the projections 35, causing the cradle body to oscillate.
Secured upon the'side' of the'gear 39 is a lever bar 40, its lower, offset'end extending to a distance below the cradle bottom and engaging between a pair of pins 41 and 42, fixed in the sides of a-bar 43, slidably engaged over the flooring 13, transversely of the cradle at one end, one end of the bar being provided with rack teeth 43, engageable with a pinion 45, forming one of the gears of a clock-work train and actuated by a coiled flat spring 46, another gear 47,
having secured upon it an operating handle 48, by proper manipulationof which the cradle may be rocked due tothe oscillations caused in the bar 43 by the pins in engage-- ment with the lever bar 40.
Actuated by an extending pin 49, set in the inner side of the rack bar 43, is a sliding bar 50, guided by brackets 51, fixed upon 56, journaled in brackets 57 below the floorecured uponthe spindle 56 is an extending crank arm 58 pivotally engaged with a connecting bar' 59, attached at its lower opposite end to the longer arm 60 of a bell-crank lever, the shorter arm 62 of which is pivotally engaged w1th a pro ection 63, extending downward from a curved brake element 64, normally drawn downward, due to the pull of a pair of tension springs 65, while the upper surface of the element 64, carries a friction plate 66 adapted to make contact with the curved exterior of the cradle body when rocked to the limit of its movement.
This brake is ordinarily drawn downward by the springs 65 except when pressed upward, due to the movement communicated by the rack bar 43 through the slides, levers and hooked pins of the wheel 55, and connections therebetween to the bell-crank lever, which serves to draw the brake elements away from or out of contact with the surfaces of the cradle body.
In operation, the handle 48 upon being oscillated transmits movement to the rackbar and then through the bar fixed upon the end of the cradle, causing the same to rock, while the effect of the springs 25, in addition to the clock spring 46 is to render the operation of the cradle relatively easy, cushioning its motion at each end of its oscillation in such manner as will be clearly ap arent.
aving thus described my invention What I claim as new and desire to secure by Letters Patent, is
1. In an oscillating cradle, the combination with a frame, a cradle pivoted therein, a braking means for said cradle body, a clock work mechanism adapted to be manually operated whereby motion is transmitted to said cradle body, and means combined therewith for actuating said brake mechanism at one end of the oscillation of said body.
2. In an oscillating cradle, the combination with a frame, a cradle having an arcuate body pivotally mounted in said frame, means for manually causing the cradle to oscillate, cushioning devices operable upon the extremity of action of said body, and
a brake device operable at one end of the limit of motion of said cradle body.
3. In an oscillating cradle, the combina tion with a rigid frame, an arcuate cradle body pivotally mounted therein, lugs extending outward at the ends of said cradle 4. In an oscillating cradle,'the combilia -60 arcuate bodypivotally mounted therein, a 1
tion with a rigidrectangular frame, an-
pinion mounted on a plane below the 'piv otal point of said body, agear fixed on the pivots of said cradle engageable with said pinion, a. ard bar secured to said inion,
said guar bar having oppositely disposed extensions, levers engageable with said extensions, spring operated plungers connected with the opposite ends of said levers, and In s extending from the ends of said cradle fiody adapted to actuate said spring plungers whereby a reversal of direction of oscillation is ment.
In testimony whereof I have afiixed my signature.
obtained at the end of its move- JOHN LOPATKA.
