SPECIFICATIN forming part of Letters Patent No. 307,287, dated October 28, 1884:.

Application filed April 23, 1884. (No model.)

,To ri-ZZ 207mm, it 71mg/ concern:

Be it known that I, WILLIAM F. GARDNER, a citizen of the United States, residing at Washington, in the District of Columbia., have invented certain new and useful Improvements in Time Controlling and Correcting Systems, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a system for automatically controlling clocks and sendingtimesignals, and is an improvement on the system granted to me in Letters Patent No. 287,015, October 23, 1883.

The invention consists, iirst, in a clock controlled by a transmitting control-clock in an observatory or other main-line circuit, with means for controlling a series of clocks from a main line and on lines used for telegraphic, telephonie, and other purposes.

It further consists in an adjustable frictional control for the second, minute, and hour hands of said clocks.

It further consists in an adjustable push-bar for actuating the cams on the arbors of the several hands of the clocks; and finally consists in details'of construction and operation of the several parts, as will be hereina'l'ter more fully set forth in the specification, and pointed out in the accompanying drawings, in which- Figure l is front elevation of the controlling-clock, showing the hand-train, adjustable cam-actuating bar, the controlling-,magnet and its armature-lever, and a controlled clock. Fig. llL is a perspective View of the adjustable cam-actuating bar, the cams, adjustable friction-springs on the dial or hands arbors, and the dial-train. Fig. 2 is a longitudinal section through the minute-hand arbor and the adjustable friction-spring; Fig. 3, a longitudinal section through the seconds hand arbor and the adjustable friction-spring; Fig. 4, a plan view ofthe seconds hand friction-spring; Fig. 5, a vertical section through one of the cams and the cam push-point; Fig. 6, a detail perspective view of the lower part oi' one of the cam push-points; Fig. 7 a front elevation of the cam-actuating bar and cams with the hands train removed; Figs. 8 and 9, detail plan view of the cams and modiiications of the adjustable friction-springs; Fig. 10, aperspective view of one form of adjustable friction-spring, the hand-arbor being shown in section; Fig. Il, a section on the lineman, Fig. 10; Fig. 12, a transverse section through the minute-hand arbor and sleeve,showing another form of friction-spring.

rI he object of the invention is to provide a time controlling and correcting system in which any corrected and controlled clock may be used as a central transmitting-clock 'for a series of clocks in a local circuit, and thus avoidthe use of an expensive primary transmitter.

The clocks herein described are not electric clocks, but are actuated by an independent dial-train entirely free from electric currents, so that no matter whether the daily correction is made or not the clocks continue to run. This system, like the one referred to in my former patent, is applicable to cities, railways, Steamship-lines, factories, Ste.

I will now proceed to describe the cam-actuating mechanism. rIhe i'ront plate, K, of the clock forms a support for said mechanism.. The cam-actuating bar, which in my former patent was made in one piece, is now made in two pieces or sections, I I', vertically adjustable with relation to each other. The upper section, I, projects above the top of plate K, and is provided with two arms, fi, which receive the free end of the armature-lever A and prevent any side movement or slipping of said lever from positive contact with the bar. This upper Vsection is slotted, as at z3, to receive a guide-screw, z2, which passes into a bloclz, e, attached to plate K. This guidescrew and slot insure a positive vertical movement and prevent any slipping 'or side movement of said bar. A spring, s, engages with a hook, s2, on the cani-bar and returns the bar to its normal position. At a point about midway the length of the piece I said section is enlarged so as to form a circular or rectangular opening, I, within which the cam moves when the bar is actuated. Said section `is then continued downward in a straight form until it unites with the lower piece, l@ which overlaps it, and is slotted at ci, in which the adjust- ICO able set-screws .c enter, and said Screws enter the piece i. 3y means el" this slot and eeteerewe the adjustment ot' the bar is ett'ected, as it only necessary to unloose said screws and Slip the lowciI section np or down and then tighten np the screws. This adjustment is valuable and important, in that a cam-actuating bar can be adjusted to clocks ot' diil'ercnt size, (by lengthening or shortening the ban) and thus il aroid the necessity ol" making; a particular nii/.e cian-bar l'or each partieulareize oloeli. lhia lower Section also has an opening, l, like the one just described, and its lower end parties through a guideiblocl, e. The alot e in the upper `Section ot' the bar and the bloei( a limit the Stroke ot' the cambar, and tlnneby check all undue strain on pivote or any part oi' the movement. A55 the eambar ia raised above the plate l by means ol' the bloelio e a', there is no friction ol" the bar on said plate. Each section ot' the bar is provided with a detachable puslrpoint, I), to engage with the cams. These push-pointe are Secured to the bar by pinej', (or in any other suitablemannen) andare cutaway at the end and on their inner i'acc, ae shown in Fir. t3. eo as to leave the outer and lower portion, Z, tlat. The inner part just above is curved, as at o', to tit the groove at the top ot' the cam, the point o centeringY with the center ot' the cam. The tlat part i ot' course extends Slightly beyond the outer lace of the cam, and ie intended to etrilie a ledge or lip7 i', on the cam, (oido Fig. 5.) ao that when the cam has been struck by the puslrpoints the ilat part i will rest squarely against the lip ot ledge Z, the center o centering.;l in the cusp oi" thc groove. Thie prevents any forwarder backward movement ot' the cams, and therefore ot' the hands. The top ol' the cam may be dat and the part o ot' the bar fiat, so that the cam may be struck squarely. l prefer, however7 the construe tion above described, lt. is prei'crrcd to have the push-points detachable. eo that it' they become worn they can be rclilaced without the necessity ol' making` a. new :a-mbar. `With the exeeption ol' the ledge or lip Z/ on the cams, said cama are plain, and are substantially the the saine and operate the saine ae in my 'former patent.

l will now proceed to describe the frictionsprings on the minute and secondnhande arbor, and which Aform an important and essential eleinent ot' my device. The cams are mounted on the seconde and minute hande` arbore and are turned by the pnslrpointe. Thin` action, which centers the ctms, also turns the hande to a'predetermined Zerovpoint, as explained i in Patent No. 207,015, and thie` movement carries the hands with them. lt ifi essential that an adjustable friction be placed on said arbore, eo as to prevent the hande being carried beyond the zeropoint, or, in other words, to bring1 about exact coincidence ol' the hande, and prevent the came and hands moving,` too far either te the right or leit't, aceordiiiigas the clock ie fast or slow. To accomplish this result l have coiniit-incted the cams, puelr pointe, and i'riei'ionfspringeJ aeehownin theaccompanying drawinge.

ln Fig. 3 the lrietion-Springv ior the seconds hand coneielii o t'a piece oi" metal. lil, peri'orated centrally and passing over the arbor n ot eaid hand, and its curved, ae there AShown, and has at one extrel'nily a slot, in. The plate lll is ilat, and has a pin, in, which entera the slotm ofthe aprilie. This engagement ot theepring and Slot causes the parte` to more in unison, and Serves another pnrpoae. ol preventinel the Spring M l'rom becoming',disengaged antislipping` oil' the llat plate M4 lt will be understood that the Spring and came` move with the hands arbore. The curved part .lil ahnte agai het a collar, c, integral with theeleevep. through which the arbor n passes. The outer extremity oi' the arbor n isScrew-threaded to receive a nut, g, which is in contact with a washer, 7i, at the end ot'sleevep. Il" it is desired at any time to increase the friction ol' the eprintr on the arbor, and therefore against. the collar c, it is only necessary to tighten np nut g, which presses lorward waeher Il, and thie in turn presses forward Sleeve p and collar c against Spring` M and expands said Spring, cantine" a greater degree ot' friction to be exerted by it and plate M on the arbor. this leesens the friction. Thie` adjustment is ol" course very slight, the turning ol' nut y the hundredth part ot' an inch gli/'infr all the adjustinent neually necessary. This friction made Vnecessary by changea ot temperature and power employed. The spring iii on the min` ntevhand arbor i passes through the plate K. @ne end abnts against the bridge-plate ii', the opposite end beingsecnred to a collar. i, made integral with or attached to the cam li". The outer end ot' arbor r screw-tlireadcd to receive a nut, q", and washer Qi. This waehcr reste aoainst the square shoulder i" ot' the sleeve if of wheel ik?, so that when the nut gf is tightened the washer preteen against ehonlderr, and this presses inward the sleeve r2, cam F', and collar t, thus compressine` Spring S, and therefore incrcafiiing` the friction on the arbor.

Havingl now described the cam bars, the cams, and friction-springe, I will describe the The reverse ot' I OO auxiliary transmitting and controlling mechanism. I will premise by stating that the cambar is acted upon by an armature-lever, A', of magnet B, as in my former patent. The arm A2, Fig. 1, which supports this magnet B, is a part of the metal frame on which the clock-movement is mounted, although it may form a part or outward projection of plate K. Secured to the horizontal arm A2 is a vertical bar, A, to which the armature-lever A' is pivoted at a'. Secured to the standard A is a bar of vulcanite, C, to which an upper and lower contact-spring, b b', are fastened by screws or otherwise, as desired. The spring b has two projecting pins or arms, il', which pass aroundy the lever A and hold the bar evenly in position. This spring has also a platinum contact-point, b2, near the extremity of its free end. The lower spring", b', is provided with a platinum contact-plate, b3, in a local circuit of a corrected clock or series of clocks, but one of which, T, is here shown. These springs are placed immediately below and in the path of the armature-lever A', so that when said lever is depressed the springs are brought into metallic contact and a local circut closed through clock T, or series of clocks, and these clocks are simultaneously controlled at the same time and in the same manner.

It is a desired feature in time-controlling and clock-correctin g systems that any primary controlled clock may be a controlling-clock for a series of clocks in a local circuit, thus avoiding the use of a large number of expensive primary transmittingclocks. It will be seen from the foregoing that this has been attained by my device, and that any controlled clock outside of an observatory may be a transmittin g-cloclr for a series, or may be used as a central transmitter, and all the clocks for hundreds of miles be corrected in one second, as is accomplished in my former patent.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
