T0 all 011/1. om. 'it may com/'ern 13e 1t known that I, (lou'rLANn CaimroN, a citizen ol` the United States', residing at lola',

in the county of Allen and State of Kansas,

have invented certain new and useful Improvements in Time-Cookers; and I do dcclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which forni a part of this specification.

My invention relates to a time cooker, and more particularly to an apparatus including time controlled mechanism for automatically terminating a cooking period, and which may be set for operation at the termination of any desired period of time.

One of the principal uses for which the apparatus is adapted is that for automatically terminating the period during which eggs, or the like, are to be boiled, and for removing the boiled articles from the water within which they are immersed during the boiling operation in order to completely terminatethe boiling operation.

It is a well known fact that the specilic period for which the eggs are to be boiled varies according to personal tastes, andl for that reason the apparatus includes a setting mechanism whereby a desired period may be set on the time controlled-mechanism and the operating parts released at the termination of thel fixed period.

In constructing an apparatus embodying the special features mentioned, I have provided improved dctails of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein Figure I is a perspective view of a time cooker embodying the features of my invention. Fig. II is a. sectional view of the same, taken immediately in front of theI clock mechanism, parts being, broken away for -better illustration. FigrdII is an enlarged detailed perspective of the time shaft and ratchet disk; showing the disk locking pawl.

Referring moreA in detail to the parts 1 designates a base upon which the operating elements of the apparatus are mounted, and which comprises a standard 2 carrying a clock mechanism 3 of any suitable type, and which is merely indicated by the casing,

as the details of structure of such clock mechanism may be of any suitable type and, therefore, form no part of the present invention. Also'supported on the base 1, and rising along the front face of the casing 3, is a standard 5, having an aperture (3 therein forming a bearing for the extended shaft 7 of the clock mechanism; which shaft corresponds to a second hand shaft, in that it makes one complete revolution per minute.

lievolubly mounted on a stub shaft i), that is carried by the standard 5, is a disk 10 having ratchet teeth 11 on its periphery adapted for travel beneath, and in proximity to, the clock shaft 7, and having a cam incline l2 at one end of the set of ratchet teeth whereby the rise from the base of the first teeth of the circumference of the disk is made gradual, for the purpose presently described.

'lhe disk carries a weight 14, preferably in the form of a radial projection, which is arranged to center over the shaft i) when the disk is set to initial position, but is adapted to overbalance the disk when moved olf center. in order to carry said disk around to a striking position; the weight when made in this forni'also serving as a striking arm, as presently described.

The clock shaft 7 carries a tooth 15 which is adapted for engagement with. the ratchet teeth on the disk when the parts are in operation, in order to move the disk forwardly one toothed space at each revolution of the clock shaft; it being apparent that when the disk is set back of center, the tooth on the clock shaft will lift the weight of the disk and striking arm, and eventually push same forwardly off center in order that it may automatically operate.

In order to hold the disk to a set position back of its center, and to determine the.

cooking periods, I provide a latch 17 comprising a pawl which is pivotally mounted i on a stub shaft 18 carried by the standard 5, and is adapted for engagement with any from one upwardly to any desired number te indicate the minutes the cooking operation is to continue; it being apparent that when the disk is set for a one minute period,

noz

the tooth 17 may be set behind the first ratchet'tooth to dragvover the Atace l2,

until the weight passes ed genterand -carries the disk around. L Q As the clock shaft 7 must .perform some.

work to carry the disk around, it is ap arent. that when relieved from its contact with the disk, it will travel idly until. it again contactsthe disk, and thereby' adord fluctuation, unless some means isprovided ferretarding its'travel. For this purpose'l pivot a Weight 20 on the upper 'endfbfl 'standard y5 above the shaft, and provide .the #Weight .with av de'- f pending lip l2l, which is adapted 'for engagement by the clock shaft tooth, so that the tooth must lift the Weight `during; its tra-vel above the disk, and thereby afford a Working substitute for the driving contact with the ratchet disk. f'

'ln order thatthe 'clock'shait tooth may take up' the Work immediately on engage.-4 ment'vvith the lip' 2l, l prdject a pin' 22 'from the side of the standard 5,'"to holdthe Weight in a slightly inclinedy positionba'ck o-its pendant center, so that' its lifting process beginsasfsoon as the'clock shaft tooth en gagesthelip, and in e'rder'to insure proper contact with 'thelip 'and tooth, llprovlde the Weight .vtith'aniarm23 which projects'over,

A spring 70 is wound on the shaft 67 with its opposite cnds engaging the base 1 and trip (39 respectively, to yieldingly support the trip in operative position, so that when the lever 3:2 is set, the trip automatically rises to functional position and returns the bracket G4 to position for engaging the holding or weighted arm Gl.

In using the device, presuming the parts to be constructed and assembled as described, the pan 36 may be set over a stove burner, with the pan 88 adjacent its forward edge, and both of the pans filled with water. The lever 32 is then connected with the chain 34 leading to the pivotally mounted vessel 35, and the weighted end of the lever placed in the notched seat of the trip bracket 42. The ratchet disk is then revolved until the tooth designation, corresponding with the number of minutes which the cooking operation is to continue, overlies the setting point. lVhen the disk is revolved backwardly to set the parts, the clock shaft is freed from the locking leaf 35 and the clock mechanism immediately starts its` operation, the clock shaft, revolving once during each minute, pushes the disk forwardly one notch` for each revolution, until when the proper time has elapsed and the clock shaft is turned the required number of revolutions, the disk is pushed forwardly until the weighted striking arm is off center and carries the pivotally mounted disk about under the influence of the eccentric weight. The revolution of the disk brings the striking arm into engagement with the beveled head of the trip bracket 43, pushing the l bracket laterally on its pivotal mounting and releasing the weighted end of the lever 32, which, overbalancing the cooking vessel and its contents, descends and lifts the tip end of the cooking vessel until the vessel is removed from the water-within the pan and its contents caused to travel down the inclined base and over the edge of the vessel into the pan 38 of colder Water, thereby immediately discontinuing the cooking operation. The weighted end of the lever when descending also rocks the hanger 50 to strike the bell and notify the cook that the. cooking operation has been completed, and after rocking the hanger, engages the trip G9 to release the weighted burner valve arm, so that the valve rod may be turned to shut off the supply of fuel. When the ratchet disk has turned sufficiently to cause engagement of the pin 26 with the leaf 25, the leaf is moved on its .pivotal mounting into position for engaging'the tooth on the clock shaft, when the tooth is brought into .striking arm for engaging the inclined tion of said bracket and rocking said position for en agement therewith, so that operation of tie clock mechanism is interrupted to save idle travel and extend the winding periods.

Having thus described my invention, what l claim as new therein, and desire to secure by Letters-Patent, is:-
