To all whom it may concern:

Be it known that I, lVILsoN E. PORTER, a citizen of the United Haven, in the county of New Haven and tate of Connecticut, have invented a new and useful. Improvement in Key-less Clocks; and 'I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked. thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

' manufacture, a simple,

' Figure 1 a. view in side elevation of an automobile clock constructed in accordance with my invention. Fig. 2a view thereof in rear elevation with a portion of the finger-button broken away. Fig. 3 a broken View thereof in central vertical section, on an. enlarged scale. Fig. 4 a perspective view of the clock proper, showing it detached from the supporting-disk and bracket upon which it is rotatably mounted. Fig. 5 a detached view in inside elevation of the supporting-disl'c on which the clock-proper is rotatably mounted.

.My invention relates to an improvement in keyless clocks of that class commonly known today as automobile clocks, though not limited to use on automobiles, the object-being to produce at a low cost for convenient and durahle keyless clock constructed with particular reference to fcwncss of parts, non-liability Auction to derangement and smoothness of winding With these ends in view, my invention consists 1n 2 keyless clock having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a cylindrical case 2 having its forward end externally threaded for the reception of an internally threaded bezel 3 formed with an ornamental bead {l and with an integral mat or reflector 5. A crystalti mounted in the bezel 3 protects the dial 7, which is applied to the outer face of a dialplate 8 carrying shortspacing-pillars9 by,

States, residing at Newthe said case-back which it is secured by nuts 10 to the front plate 11 of the clockanovement which also comprises intermediate movement-plates 12 and 13 and a rear movement-plate 14:, the said movement-plates being secured together in proper relative positions in any suitable manner as by pillars 15. The clock-mov ment may be of any approved construction as to its train which it has seemed suflicient to designate by a single reference numeral 15.

Near its rear'end the case 2 is provided with a disk-shaped fixed back 16 soldered or otherwise secured in place and having the clock-movement secured to it by short spacing-pillars 17 which are riveted in the rear movement-plate 14 which receives screws 18 passing from rear to front through Fig. 3, whereby the clockrmovement is fastened to or organized-with the case 2 so as to rotate therewith. The short spacing-pit lars l7 establish betweenthe re'armovemenh plate. 14- and the case-back 16, a narrow space 19 for the reception of the main yiinding-ratchet 20 of the clock-movement, this ratchet being fixed upon the main windingarbor 21 which extends forward through the rear movement-plate 14: in which it has bearing and through the spring-barrel 22 and is formed at its forward end with a trunnion 23 hearing in the middle of-the intermediate movement-plate 13. The said arbor 21 is formed with a hub 24- to which the inner end of the main-spring .25 is socured in the ordinary manner, the outer end of the said spring being attached to the periphery of the said spring-barrel. Near its extreme forward end the arbor 21 is formed with a shoulder 26 forming a bearing for the main-wheel 27 to which the s1nfing-barrel 22 is secured, the said wheel 2'? rotating upon the shoulder 26 which remains at rest. The arbor isv also formed with a shoulder 28 passing through the center of a diskshaped plate 29 employed to close the springbarrel A pawl 20 pivotally mounted upon the rear face of the roar movementplate 1-1 and provided with a spring 30 and located Within the space 19 aforesaid, en-

the said disk Set and are located in a plane 2 and therefore the clock morement are normally held against rotation by means of a coupling-gin 3t provided at its rear end with a knurled finger-button and mounted for rotatable and longitudinal movement in a 1 lb 533 titted in a supportingatislt or plate ill fitting within the rear edge. of the case 2, and attached by screws to a bracket 36 too perforated cars 23? of which project beyond the edge of at. an angle to the plane thereof so that the clock will he supported in an inclined position as shown .in Figs. 1 and when it to he used as an automobile clock. it course the construction of the bracket 36 will depend upon the use to which the clock to be put. The said plate 3% and bracket lt' .stitute the clock-base or clock-supporting means and remain fixed while the clock s being rotated tor the winding of its spring. At its extreme forward end the coupiinwpin lit is reduced in diameter to form a nose lo adapted to enter a corre sponding hole All in the outer face of the casebuch it). When the nose 3S entered into the hole 39, the case 2 will be coupled to the plate ll and the case and movement held against rotation. A spring to encircling the inner end of the pin 33L exerts a constant eti'ort to hold the. nose in the hole lth this spring being interposed be tween a stoprollar ll nuainted upon the pin 31 near the forward end thcreot' and an ahutmcnt h] within the hub 33. For titling the n so 219 out of the hole Ill) and holding it in its rctrartcd position, the outer end oi the hub m is formed with a liftingcam which is engaged by a lilting-pin it mount d in the coupling-pin ill ainlriding upoir the surface of the cam l t-l. lreparator to winding the main-spring 25; the tingei'lutton 32 is grasped and turned from let: to right. whereby thelit'ting-pin ll rides rer the ti ling-cam ill with the cited; oi" retracting the coupling-pin 31. against the tension ot the spr ng it) and withdraw ing the eouplingnose :lov from the hole 39, leaving the cloclt-movement; and the case 2 tree to be bodil rotated with respect to the main windingairhor 2i and they clockbase. consisting. as shown, of the plate 3i and the bracket no. the pin 31 being niainiained in its retracted position by the lid ing oi the lifting-pin 4A up over the cam 4:?) out onto th level outer edge of the hub 33. After the inaiinspring 25 has been wound, the tingerbutton 32 is turned in either direction until the lifting-pin it is brought into registration with. some part of the cam l3. Now, when in the rotation of the casehaek it) with the case 2, the hole 39 is brought into registration with the nose 2-58, the spring it) Will at once act to push the coupling-pin 231 forward and enter its nose 38 into the hole 3'3, whereby the clock-case 2 will be again coupled with the clock-base and held against rotation.

Inasmuch as in my improved construction, the clock-movement itself rotated, its dial 7 must also be rotated with it. This makes it necessar to provide for resetting the dial, so to speak in an upright position after the spring has been wound, that is, with the 12 on the dial, uppermost. For this purpose I employ, as herein shown, a dial-reset ting ratchet l5 located within a narrow space it) formed between the case-hack 1t) and the supporting-plate 23lb r the interposition between them of a f-rpacing-ring 47 or some equivalent thereof the said ratchet being formed with a shoulder 48 hearing in an opening it) in the center of the supporting-plate 25%. The said ratchet 45 is formed with a square central opening 50 for the reception ot-the squared outer end of the mainwinding arbor 21 with which the ratchet rotates from right to left when the dial being reset but at no other time. A pawl 51 pirotally mounted upon the front face ofthe supporting plate Siand provided with a spring 52 enacts with the ratchet-t5 and prevents the arbor '21 from turning from lett to right.

When the clock-ease and the clock-movement; are being bodily turned from left to right for the purpose of winding the mainspring '35, the main-arbor 2t and the ratchetwheols 20 and 15 remain at rest the arbor being held against rotation by means of the en gagement ot the pawl 51. with the ratchetwlh, while the pawl :H o t the main-ratchet- 20 is being trailed over the teeth of the same, since the said pawl '29 is carried by the rear move- -ment- )late it which revolved as a part of the clock-movement. This provides for the winding of the clock. Vhen the clock has been wound, it still remains necessary to reset the dial 7 so as to properly position its figure 12, since the chance of the figure '32 on the dial being in its proper uppermost p0-' sition atthe conclusion of the operation of winding the clock, would be only a remote chance. The resetting of the dial. is doneby bodily turning the clock tronrright to left for the required distance which will always be. less than one entire revolution. During this reverse movement of the clock for the purpose of resetting the dial, the arbor 2t will rotate from right. to left, and turn both.

of the ratchet wheels 20 and l5, .the pawl iz) of the ratchet-Wheel 20 being engaged w th the same while the ratchet-wheel ton-ides under the pawl 51 carried by the supporting plate 34. The turning of the clock proper from left to right for the pur ose of winding the main-spring 25, is 0? course done against the tension of the main-spring, but theturmng of the clock from right to left for resetting the dial, is done only against the tension of the pawl-spring 52.

The organization of parts forming the clock proper, (the clock-case 2 and the clockmovement), are coupled to the clock-base (the plate 44 and the bracket 36) by the passage of the rear end of the main windingarbor 21 throu h awasher 53 set intoan opening 54 in the bracket 36, the projecting rear end of the arbor receivin a fasteningpin 55 the removal of whic enables the clock proper to be removed as shown in Fig. 4.

It will be seen from the foregoing that in my improved keyless clock, the clock-movement and its case'are bodil rotated for winding the main-spring, w ile the main winding arbor remains at rest, whereby I dispense with the use of the ears necessary in keyless clocks employing ezels or shells for winding the spring.

I claim 1. In a keyless'clock, the combination with a clock-base or supporting means, of a clockmovement bodil rotatable in either direction, and a winc ing-arbor coupling the said movement to the said base or supporting means, and held against rotation when the movement is rotated for winding the clock but rotatable with the movement when the Zan'ie is reversely rotated for resetting the 2.
