To all whom 'it may concern:

.Beit known that we, SYLvnsrun F. WinsoN and WILLIAM L. FIELD, citizens ofthe United States, residing at Los Angeles,

Athe county of Los Angeles and State of California, have invented-a new and useful Ohronometric Bab -Tender, .oi which the following is a s ecl cation.

The object o this invention is to provide improved means `for soothing children and putting them to sleep by Aconstantly-recurrin movements in measured time.

1 he object is to mount a baby-crib and apply power to the baby-.crib so that .it will have a softly-swaing motion in every direction in measur time.; and my invention includes an open rectangular frame, a babycrib., a series of springs for suspending the crib loosely with-m the .frame, a series of springs for centralizing the .crib within .the frame, a motor, and a universally-yielding, adjustable connection between the motor and the crib.

This invention relates to a tender having a resiliently-.supported carriage that may move down and up and laterally with an easy freedom of movement, and consists in novel meansv and combinations whereby the movement of the occupant of the babytender ma be effected in a su erior manner Without jollss or j ars, and whio is 4adjustable for tending babies of ydHerent We' hts and for changes from 'heavy to light bed and vice versa, as the changes of the seasons occur.

The invention includes the novel appliance and various parts and combinations of arts hereinafter particularly .described an claimed.

The invention may be embodied in various forms, and we do not lpropose to limit the same to any. specic construction.

The accompanying vdrawings illustrate the invention in the form at :present deemed most desirable.

gs. land. Figis -a section on line Flg. 4, showing motormechamism from same side as in 1. Fig. 9 is an fend elevation of the motorrnechanism from linear, Fig. 8.

1 is` a. suspended crib carriage or basket resiliently he d by supporting s rings 2 and sta. -springs 3 which are carrie by a frame 4 t at surrounds the carriage l, and within which frame the carriage `1 may move u and down and may also swing sldewise an. endwise.4

5 designates -a motor which4 may be of any suitable construction and may be operated by electric or other power determined upon by the constructor. In the drawings a spring motor is shown, the same constituting a part of this invention, for the purpose of applying the broad idea of means-in 'the simplest and most' economical and convenient form for general use. I

tion from the left of Fi and 36 having casters 37 at .their lower :ends .to travel lon the floor; the 'upper side rails 38 and 39 connecting the posts 33, 3.4, and 35, 36, respectively; the upper'end rails 40 and 41 Aconnecting the posts 33, 35, and 34, 36, respectively, and forming a rectangular open .frame to receive the crib. The lower side rails 42 and .the lower .end rails 43 connect the este intermediate of their ends `and serve as races, and rounds 44 are inserted vertically between the u per rails `and .the lower rails. The frame time constructed is adptcd to run upon the loor so as to `be ea y moved from lace to place. Sills 45 and 46 are inserte erosswise of the lower side rails 42 to support :the motor 5.

The crib 1 lcomprises the rectangular metal base 47 corres yending in shape to the rectangular frame 4 uit foomsiderablysmaller in size; the rectangular wooden bottom 48 placed the base 47 and secured there- .to the metallic rounds 49 extending upwardly trom the base 47; the rectangular .inner .edge wire 50 secured to the upper ends of the rounds 49; the braces 51 extending outwardly .and upwardly from near the l u per Aends of some lof the rounds 49; vand rihe frame 4 comprises posts 33, 34, 35

the Way around the base 47 so as to form a complete inclosure consisting of a bottom and a vertical wall or fence and open at the top to receive the baby.

Said motor is arranged to turn a crank 6 which is Connected by a rod 7 with a resllient walking-beam 8 pivoted on a fulcrum- 111 a, carried by the frame of the motor 5 an adjustably connected with the bottom of the carriage or basket l.- The connecting means between said walking-beam and the basket is preferably adjustable in order to facilitate the regulation of the device for operation with different loads in the carriage or basket.

For this pur ose said connecting means comprises a resi ient link 9 connected to the resilient walking-beam on the other side of the fulcrum a from the connecting rod, and a temper-screw 10 connected with the bottom of the carriage or basket b a universal joint 11 and connected with the ink 9 by a pivotal nut 12- Said temper-screw l0 is provided with a handle 13 by which the screw may be turned, thus raising and lowering the nut 12 and thereby increasing or decreasing the tension of the spring that forms the walkingbeam 8. Preferably, said Walking-beam is formed of a fiat sheet-spring capable of being deliected from its normal resistance to stop the motor in case the opposite end of the walking-beam is held stationary by the cari riage or basket. Other forms of spring may be used, but the flat form is at present deemed preferable. The resiliency of the walking-beam is suflicient to move the carriage or basket up and down when the Walking-beam is Worked by the crank 6. When power is applied whereby the crank may be rotated and the carriage or basket is free to respond to the impulse of the Walking-beam, the ap liance may be started into operation by pusiing up or down on the carnage and then releasing the same so that it will be freely carried by the spring. The force of the motor will then be suiicient to maintain the up-and-down motion of the carriage so long as the carriage is free to respond to the forces at work. The eriod of the u -anddown movement of the carriage very much depend upon the load in the carriage. The heavier the load the slower will be the movement; and it is important that` the impulse of the Walking-beam be given at the lntermediate position of such beam in order that the momentum of the load will operate tocarry the crank past the dead center. By adjusting the temper-screw 10 to bring the Walking-beam to such intermediate position: that is to say, a level position when the carriage is at rest, the appliance Will be made to operate freely whenever the carriage is starte to move up and down.

In order that the appliance may be operated with the utmost convenience and smallest expense, a spring motor is provided in which the spring shaft 14 that is driven by the spring 15, carries the driving wheel 16 which is constantly'in mesh with the Winding pinion 17 that is fixed to the Winding shaft 187 and with the ratchet driving pinion 19 that 70 drives the ratchet 20 which is carried by a wheel of a train 21 that drives the crankpinion 22 mounted on a shaft 23 on which the crank 6 is fixed. 24 is a detachable crank for the winding-shaft 18. The motor may be wound by the crank 24 in the socket 25 on'the winding shaft 18. As the spring 15 is wound, the drivin Wheel 16 rotates in a direction reverse to tat indicated by the arrow in Fig. 8. When the winding has been so accomplished the crank 24 may be Withdrawn, thus leaving the spring free to drive the driving-Wheel 16 in the direction of the arrow shown in Fig. 8, thus setting the train in motion to drive the crank-shaft 23 when- 85 ever vertical oscillation of the carria e is set up. Such oscillation may be initiate by the movement of a child in the carriage, or it may be initiated by the attendant. In either case, the motor operates to keep u the oscillation until stopped by externa force, or until the motor runs down or becomes ino erative. The crank and the resilient walliing-beam o erate as an escapement, and the weight of t e carriage in the nature of a pendulum to cause a chronometric movement of the .carriage so long as the motor is operative or until the carriage is stopped by some external force.

The swivel nut 12 is connected with the link 9 by universal joint 26 so that the operation ofthe device will not be interfered with by deections of the carriage from vertical position. The centralizing stay or springs 3 are pivotally connected with the carriage at screws 27 to the intermediate rounds 49 of the sides and at the eyes 28 secured to the rounds 49 of the ends of the carriage, and with eyes 29 at the corners of the frame so that a limited endwisel and side- 110 Wise movement of the carriage will be allov'ed. v d v e suspen sp s 2 are fastened to the upper side irlfiixls SngQ, and to the upper end ralls 40, 41, of the frame, cured to the bottom of the crib or carriage, by the rods 53 having eyes at their outer ends to receive (tihe (lirpos iat tlhe (finds dof the springs; sai ro e' ace un er the bottom -board 48 anduslcupi'ed to the board 120 by screws, rivets `or nails 54; said rods 53 extending outwardly from, the bottom all the wayaround so as to centralize the crib 1 relative'to the frame 4. ATwo sets of centralstay or guy springs are arranged at dif- 125 ferent levels, one set, 3,'being rovided at. the top of the frame, and fastene to the carriage about midway between its top and bottom, and the other set 3 being connected at 31- with the bottom of the carriage and at 32 130 and are se- Y Y ducing the load in the carriage.

The crib or carriage 1 is suspended in the frame 4 by a series of springs extending all the way around so as to cushion the crib and allow it to move yieldingly in eve direction. The universal joint 11 shoul be a plied to the bottom 48 as near as practicable to its center so that when the power is ap plied the tendency will be to move the cr1b almost straight up and down, or so that power will be'. app ied equally to all parts of the crib. The connecting-rod 9 and the resilient w -beam 8 provide-a cheap and sim le ylelding connection betweenthe power evice and the crib thatis peculiarly adapted 1 to transmit the motion to the crib gently and that aiords readyand convenient means for mterposing between the walking-beam and the crib, an adjusting device forincreasing andI decreasing the tension of the s ring through which the power is transmitte' I claim.:-
