To @ZZ whom t may concert/t:

Be it known that l, ARIE DE Vos, a citizen of the United Stetes, residing at Des Moines,

. in the county of Polk and State oi Iowa, have I the construction, errangement, end. combina-- invented a certain new d hereinafter more inllyrset ally-Wound Clock, of which the following is a specirloetion.v f

The obiedts of my invention are tovprovide 1a c-loelr of this class of simple,y durable, and

inexpensive contruetion.

` Referring to the accompanyind drawings, I have used the reference-numeral cate that part of thev clockframeshown The numeral 11 indicates'one of a train of pinions eonstituting the clockwork mechanlsm. itis to be understood that any ordinary clockwork mechanism may 1oe used in connection with i my improved electrical winding mechanism. lience'it is not neces sary to show and describeany specific hind of cloclmvorlnk l The means Jfor Winding the clockwork mechanism comprises a short arbor 12, secured to the front of the clocleframe to support a hubl, which is vrotatablymounted thereon end winch is formed with a pinionv .1 4, in mesh with the pinioni 1 of the train of pin- The numeral 16 indicates a and useful Electriom 4freine adjacent to 18 moves downwardly,

hub 16 is a lever 18, provided at one end with v e Weight 19. Mounted on the lever 18 is e. sprinog-ectnatedv pawl 2() to en age the ratchet-wheel 15, andvpivoted to t e clocks evity-pawl 21. rlhese pawls o crate as iollows: When the weighted end o the lever the spring-actuated pwl`20 rotates the' retchet-wheel 15, the .other pawl droppingirom one notch to the the ratchetheel the ratchet-wheel 15 iss' froni moving baclrwardly. ,Then when the weighted end of -the lever moves upwardly the pawl 21`holds the ratchetwheel 1 5 against rotation and the -pnwl moves Jfrom one notch 'to the other thereof. indicates a. sto fixed to the front of the clock-frame to limit the upward movement of the weighted lever.

The weighted lever .1s loperated as follows:

en armature pivoted at 25 to swingvfrom a. position in engagement with the armature up-v wardly to aV stop 26, which limits its upward movement. Fixed to the armature 24 is a lug 27, to whcha dicates e link pivoted to the weighted lever 18 and provided with a slot 30', through which a screw 31 'is passed, which screw is seated in the upper end of the link 28, thus providing a slidin connection between the links 28 and Viren the armature is moved toward its magnet,l the weighted end of Vthelever is elevated, and then when the magnet no' longer attracts 'the' armature the weighted end of the lever slowly descends and rotates the pinion 14, which winds thetrain of pinions of the clock, YWhen the armature is drawn toward its magnet it moveswith great speed, vand since the screw 31 is at the bottom of the slot 'the weighted lever is thrown upwardly with considerable force,

and its momentum carries it farther than it between the armature and weighted lever. Hence the pawl 20 passes over a number of The numeral 22 The numeral 23 indicates -an electromagnet Y' ",Inounted in the clockfirame, and 24 indicates link 28 is pivot'ed. 29 inv the 'teeth and the weighted lever held by the pawl at the highest point it reaches, thus achubirotatebly tuating the 'clockwork mechanism for a roo would go if there were no sliding'connection longer time than ii its upv-fard movement were limited by the movement of the armam ture.

l have provided means for autometio-ally closing an electric circuit thro ugh the electromagnet just before the weighted end of the lever reaches its lower limit of movement as follows: The numeral 32 indicates the bottery, und indicates e conductor leadingl from the battery to a metal bracket Se. Pivoted to the bracket 3e is a circuit-breaker 35, having an arm 36 engaging the top of the bracket to limit the pivoti l movement of the circuit-breaker in hoth dicctions. Extending downwardly from tl circuit-breaker 35 is e metal arm 37, and ecent to it is an erin y38, made of a non-conductor of lelectri'city.

The numeral 39 indicates a coi'itractible coilspring connected at it@ ivith'the 1oracket Se,

assed acrossthe pivotal point of the circuitreaker 35 and attached to en arm el on the circuitlbreaker. By means of the spring the circuit-breaker is automatically moved to its 'limit in both directions when the erm el thereof has passed a oint in alineznent from the point 40 througlli the `ivotal Vcenter oi the circuit-breaker. Fixedpto the armature 2li is an erin 42, having a projection on its upper end projecting between the arms 37 and 380i' the circuit-breaker. A. conductor 4-3 leads Afrom the bracket 440i the'arniature to the electromagnet, and e. conductor i5 leeds from the electromagnet to the battery 32. In the practical operation of this part ol the device and assuming the circuitbreaker to be in the position shown in solid lines in Fig. l, the spring 39 is above the pivotal center of the circuit-breaker and yieldiiily holds the insulated arm of the crcuitreaker against the erm 42 of the nrmature. As the armature nieves upwardly it 'forces the erin 38 of the circuit-breaker with it until the s )ringr 39 passes below the center of the cucuit-breekei'- Then thespring quickly tl'u'oivs the circuit-breaker to position, with the arm 37' thereof in Contact with the arm e2, thus establishing a circuit through the electroni agnet. The position of the circuit-breaker as required to establish a circuit is shown in Fig. 5. ln this connection it is to be noted that ii for any reason the electromagnet should fail to attract the armature when the arm 37 thereof lirst strikes the arm 42 of the armature then the arm 42 continues tovmove sway from the arm 37 to position out of contact therewith, i as clearly shown by dotted lines in Fig. 5.

The advantage of this feature is that it for any reason the ermature should fail to move tov/ord the magnet when a circuit is estabhshed then the weighted lever will continue the upward movement of the armcture until the circuit is broken, thus preventing the but to be et upper limit of movement the'circuit-breaker is held in position witli'its insulated arm 38 in engagement with the erm Then as the Weighted lever slowly descends it operates the clockwork 'mechanism and elevates the armature. 'When the armature is neer its upper limit spring 39 quickly raWs the 'circuit-breaker to position with the arm 42 'thus establishing circuit. As soon as n circwit is established the armature ettre cted toward 4its thus causing the arm l2 to push nagainstthe arm 37 of the circuit-breaker and'niove it to position with the springr 39 above the `center of the circuit-breaker, tllus'ceusing; the :Boring- 'to throw the circuithrefiker to oneiliniit of its movement, with its insulated -arnil in engagement with the arm 42, and et the time elevatingf the Weight.

Having'thus described my invention, what l claim, and desire to secure by'lxetteisi'ntent of the United States therefor, 'isA The combination of a clockwork inechnn ism, an electric circuit, an clectroniegrnet'ineluded in the circuit, a movable nrmeture'lior the magnet, a yielding pressure device ranged to have power stored in bythe movement of the armature toward 'the intagnet and also arranged to operete'the-clock- Work mechanism by its own power, a 'con- 'tact-point movable by the arrnaure-andin eluded in the circuit, a second contactspoint in the circuit to he engaged bytlieiirst, e contact-arm attached to vthe armature and included in the circuit, a second pivoterlcon- 4tct-arm included in thel circuit and in posi tion to be engaged by th'e'itinst ture approaches its limit ci mo". e. from the magnet, and a limitingh :l ranged to stop the pivoted contar-crm'bcfore the armature reaches its limit of move- 'ment away form the magnet to permit said contact-arm on the 'ain'iature to possv out of engagement with the pivoted contact-arm 'at the end of its movement away from the ermature, in the event that the magnet should fail to attract the armatiu'e.
