TIME-PIECE SPECIFICATION forming part of Letters Patent No. 309,306, dated December 16, 1884.
Application filed January 15, 1884.
To all whom it may concern.-
Be it known that I, Josnrn Lrnnxnnn, of the city, county, and State of N ew York, have invented certain new and useful Improvements in Time-Pieces, of which the following is a specification.
My improvements relate to a new method of indicating time. Heretofore it has been universally indicated by means of a dial or face plate with figures representing the hours placed radially thereon, and a hand or hands for pointing to such figures. Nearly always, when written or printed, the time is expressed in figures in one lineas seen, for instance, in railroad and steamboat time-tables, in the newspaper advertisements, &c. A timepiece, to express the hours and minutes on its dial or face plate, so that it can be read the same way, is the result of my invention. To effect this, mechanism has been devised by DH, and placed in combination with a dial or face plate containing, instead of a circle of figures with hands or pointers, as before referred to, a series of openings, in which the hours and minutes are at proper intervals exposed to View. The new division of time into hour-belts over the country can by my invent-ion be efficiently registered, and the change easily computed when passing from one belt to another. In case such computation and division of time is made universalthat is, extended around the world, doing away with the a. 1n. and p. m. distinctionmy invention would be equally applicable to such system, as it will only be nec essary to continue to expose the hours in one of the dial-openings up to 24, instead of stop ping at 12. Thus, for illustration, half-past ten oclock p. 111. would be indicated 22.30, (twenty-two oclock and thirty minutes.)
I will now proceed to describe a mechanism by which I have worked out the continuous indication of time by hours and minutes on a dialor face plate without the aid of figures permanently attached thereto, and hands or pointers in connection therewith.
In the drawings, Figure 1 is a dial or face plate, to be used in connection with the operative mechanism of a time-piece, exposing thereon the correct time in hours and minutes by figures. Fig. 2 is a front view showing one (No model.)
arrangement of disks for carrying out my invention, each containing a series of figures thereon,in this particular instance, for indicating hours from 1 up to 12, and minutes from 1 up to 59, inclusive. Fig. 3 is a view of the interior mechanism of a time-piece employed for operating these disks, constructed according to my invention, the frontpillar-plate and said disks being removed. Fig. 4 is a horizontal cross-section of said mechanism, taken in the line 00 a." of Fig. 1. Fig. 5 is a detachedview of the ratchet-wheel mechanism for the mainspring. Fig. 6 is area-r view of the whole mechanism of the time-piece, a part of the rear pillar-plate being shown broken away to exhibit some of the more novel elements comprised within my invention. The older and wellknown elements, such as the trains of wheels, escapement, &c., are represented by dotted lines. Fig. 7 is avertical cross-section taken through the line y g of Fig. 6. Figs. 8 to 13, inclusive, are detached views of some of the novel elements comprised within my invention.
Old elements, such as mainspring, the train controlled by the escapemcnt, &c., will not be described with unnecessary detail, as such are well known in the art, and can be modified or rearranged without affecting the character or nature of my invention.
1 is the front pillar-plate, 2 is the rear pillar -plate. 3 is the arbor, upon which the mainspring is placed, pivoted in the rear pillar-plate, its front end extending through the front pillar-plate and the dial or face plate, for conveniencein winding. 4 is a mainspringbarrel having the outer end of the spring connected to its inner periphery. 5 is the greatwheel rigidly attached to the end of this barrel, but moving freely on the arbor 3. The other end of the mainspring is connected to this arbor by the hook 6. Another greatwheel, 7, turns with the arbor 3 in the running down of the time-piece, but does not its pawls acting 011 a ratchet-wheel, which is rigidly connected to such arbor. (See Fig. 5.)
The object of the great-wheel 5 is to move the train of wheels which is controlled by the scape-wheel, and by means of which the mim turn with it in the winding up by reason of IOO ' its pinion 13 gearing with wheel 10.
ute let-oft is directly, and the hour let-off indirectly, timed. The great-wheel 7 moves a train of wheels which furnishes the power to move the figure-disks at the change of the minutes and hours, as the same are continuously and timely let off through the time-train of wheels and its eseapement above referred to.
The time-train of wheels controlled by the escapement is constituted as follows: 8 is the first wheel, its pinion 9 gearing with the greatwheel 5. 10 is the second wheel, its pinion ll gearing with wheel 8. 1.2 is the third wheel, 14.- is the fourth wheel, its pinion gearing with wheel 12. The escapewheel 16 has on its arbor a pinion, 17, which gears with the fourth wheel, 14. The kind of escapement here used does not require any description in detail. Its form and kind can be varied for different styles or sizes of timepieces embodying my invention.
The train of wheels which furnishes the power to turn the minute and hour disks is constituted as follows: 18 is the first wheel, its pinion 1.) gearing with the greatwheel 7. 20 is the second wheel, its pinion 21 gearing with wheel 13. 22 is the third wheel, its pinion 23 gearing with wheel 20. To the second wheel, 20, is geared a pinion, 24, rigidly fixed on a sleeve, This sleeve and pinion work loosely on a shaft, 26, such shaft having one end pivoted in the rear pillar-plate and the other extending through the front pillar-plate, so as to obtain its other bearing in the dial or face plate. The sleeve 25 extends through the front pillar-plate, and has attached to it between such plate and the dial-plate the disk 27. On the outer edge of its surface facing the dial-plate are placed at equal distances the units of the minutes in thehour-namely, 1 to 9, inclusivewith a zero (0) to aid in indicating the minutes above nine in connec tion with another disk, hereinafter explained.
On the shaft 26, upon which. this sleeve 25 and disk 27 have free motion, and between such disk and the dialplate is rigidly attached another, but smaller, disk, 23, placed within a dished portion of the disk 27, and so that the exterior surfaces of the two disks shall be flush with each other. Upon the outer edge ofthis disk 28 and facing the dial-plate are placed at equal distances the figures 1 2 3 1 5 0, so as to obtain the tens of units of the minutes up tothe even hour. From thelast min ute of the hour (59) we go for the time to the hour-disk, which will be presentlydescribed, the disks 27 and 28 then each exhibitiugzero, thus 0 0. 29 is an opening in the dial-plate, which brings into View simply those portions of the surfaces of the two referred-to disks, containing the units and tens of units of the minutes indicated by the run of the timepiece.
1 will now proceed to explain how these minute-disks are operated to properly determine the faction of the hour. To the third wheel, 22, is geared a pinion, 30. The shaft 31, carrying the pinion 30, extends through the rear pillar-plate. To such end of the shaft is attached aletoff bar, 32. The bar makes but half a revolution at the end of every minute by reason of its being controlled by the time-train of wheels. This periodic semi-rotation of the let-off bar is accomplished by means of a mechanism operating between the timetrain and the train giving power to oper ate the figure-disks. There is an opening made in the rear pillar-plate above the let-off bar and about midway between it and the rear pivot of the fourth wheel, 14, of the time train. 33 is a small block hinged at 34 on the inner side of the rear pillar-plate. 35 is a cook or bridge attached to this hinged block, so as to project through the said opening and to hold pivoted between it and the block an axle, 36. This axle carries an enlargement or spool, 37, to which is rigidly attached abarconsisting of two arms, 38 and 39, one, 38, extending upward inside of the pillar-plate bifurcated at its end, so as to grasp a cam, 40, rigidly attached to the arbor of the fourth wheel, 1%, between such wheel and the pillarplate, and the other, 39, extending downward on the outside of the pillar-plate, having at its end a circular enlargement carrying two short pins, 41 and 42, proj eeting horizontally outward and obliquely arranged with reference to each other, so that one shall be a littlehigher than the other. This bar, cousistingof two arms, 38 and 39, is shown in Figs. 12 and 13, in the extreme right and left position assumed by it through the throw of the cam on the arbor of wheel 1i, that shown in Fig. 12 being the throw of the bar by the eccentric 40 to the extreme left having reference to the lower arm, 39, and so as to arrest the let-off bar 32 after its complete let-off, in order to indicate the next minute. The let-off bar is now shown with one ofits ends resting on a pin, 41, Figs. 7 and 12, at the commencement of the minute, and as the cam 40 moves in the direction of the arrow, the arm 53$) moves off to the right, and between the thirtieth and forty-fifth sec ond the end of the lct-otf bar drops from off the pin 11 onto the pin 42, thus performing the partial letoff. The cam 10 has now assumed the position shown in Fig. 13, and the arm 3.) moves to the left during the remainder of the minute, (fifteen seconds,) which causes the pin 12 to move away from the end of the letoff bar 32, so that a projecting stud on the end of the let-off bar can now pass freely between the pins 41 42, allowing the bar to turn, so as to bring its other end up to be arrested by the pin etl, which is now placed in its path, thus causing the completelet off and the turn ing of the minute dial to the next minute to be indicated. Thus is the connection made between the time-train and the minute and hour disk train, and the minutes expressed consecutively.
The operation of the complete let-off of the arm 32 is as follows: The pinion 30 011 the arbor of the let-off arm 32 is turned by the third TIO wheel, 22, of the train driving the disks. On the arbor of the third wheel is the pinion 23, which is turned by the second wheel, 20. The
second wheel, 20, also turns at same time the pinion 2i, as before stated, a sut'ficent distance to change the unit of the number of minutes. The pinion 21 on the arbor of the second wheel, 20, is turned by the iii-st wheel, 18. The great-wheel 7 drives the pinion 19, which latter is situated on arbor of first wheel, 18, as h'ereinbefore explained.
The tens of minutes are changed as follows: The shaft 26 has a small hexagonal-sided block, 43, rigidly fixed onto it about midway between 11 (pillar-plates. Upon one face thereof are placed six pins at equal distances from each other, virtually torming a six-leaf pinion. Upon the arbor of the second wheel, 20, underneath this pinion, are two disks. ti and t5, rigidly connected to each other and to the arbor. The periphery of disk 44 is immediately underneath the block 43, and has at six equal intervals depressions 46, so deep and wide that when a depression coincides with a side of the block 43, the block can be turned on the periphery of the disk it within such depression. On the disk at equal distances from each other, are six projections or teeth, 46, for gearing with the leaves of the block 43, one of each of such teeth 1-7 being opposite to one of the depressions 445, so that it will at on one of the leaves of block 43 and give the said block one turn, while one of its sides coincides with and is within one ol:- such depressions to. This being at the sixth of the hour (every ten minutes) permits the shal't 24; to be turned sul'iiciently to exhibit a ligure representing the tens oi minutes in the openin 2.) of the dial or face plate. The lastfinovemcnt after the live will be-O, or a space merely, be-
cause of the exhibition of the full hour at that interval. As soon as the block 43 is so turned on its edge, the iixed disks at and .5 move away, and its adjacent hexagonal. edge rides on the smooth periphery left between each two depressions {to of disk it (see Fig. 8) air til another sixth of the periphery is moved along and it reaches the next depression #lti, representing ten minutes, or the sixth of an hour, when the same operation of the partial rotation of block a3 is repeated. The hexago nal block 43 is retained in lixed position against such periphery by the gentle action of a spring, 47, the freed end of which rests against one of its edges, the other end of the spring being affixed to the upper left-hand pillar. As this shalt 2o makes a who e revolution once an hour, I place on it. between these fixed disks 44 45 and the rear pillar-plate, a snail, 48, by which will be let ot'i' the hour mechanism at each completion of the hour by the units and tens of units of minutedials through the shaft 26 and sleeve 25.
The mechanism controlling the hour-dial is as follows: At the left end of the pillar-plates is ashaft, 49, one end being pivoted in the rear pillar-plate and the other end passing through plate.
the front pillar-plate, and having keyed thereto between the front pillar-plate and the dial or face plate a disk, 50, on which are-placed the hours consecutively in a circle from one upward. An opening, 51, is made in the dialplate, so that the hour indicated by the operation of the trains may be observed. 52 "s a disk on this shatt lt), containing in its periphery as many notches 53 as there are hours represented on the hour-disk, such number being twelve in the timepiece herein described. 5st is a shalt pivoted in the pillar-plates, containing an arm, 55, which has a pin, 56, projecting out horizontally from its free end,which drops into one of these notches 53, to keep in aiixed position the hour-disk, except while the disk is being moved to exhibit the next succeeding hour, when it is elevated out of such notch in manner as hereinafter explained. A spring, 57, impinging upon the top of this arm 55, extends horizontally out from the inner face of the front pillar-plate and serves to give the required gentle pressure on the arm 55, so that its pin 56 will always drop promptly into a notch at the proper instant and remain there until removed therefrom. On the shalt 49, between this notched disk 52 and the rear pillar-plate, is ahollow arbor, 58, carrying a disk, 59, which latter abuts close up against the notched disk 52. At (30 on disk 59 is a short projecting arm, carrying a pawl, (it, having a spring connected to such arm, and impinging on the back of such pawl in the usual manner, which pawl. will at the proper interval of time take into one of the notches of disk 52 and carry forward such disk the dis tance 01' one noteh-that is, until the pin 56 of arm 55, which has in meantime been withdrawn from the notched wheel, again engages with I the next adjoining notch in it.
In order to withdraw the pin 5o irom out of the notch,
there is hinged at we a loose block, 63, carrying a pin, (it, which projects toward and overlaps the pin 56 up to the side of the notched disk The pin (32 rides on the periphery of disk 5t), which periphery is nearly flush with the bottom portions of the notches of disk At a n'ojection, (55, on disk 59 is hinged an arm, (5o, bifurcated at its other end, 67, so as to embrace the arbor of the second wheel, 20, between the snail l8 and the rear pillar- Contact between this arm 66 and the periphery of the snail is made by means ol the pin (55. At (39 on disk 58 is riveted an arm. 70, Carrying a weight, 71, serving from its po sition to keep the pin 68 in close contact with the snail, and so that as the snail rotates, bringing its greater diameter out in the direction of the hourdisk mechanism, the arm 66 will be moved in same direction, carrying up the weight 71, also the pin 64, which is beveled, Figs. 10 and 11, so that as it approaches the reduced end of pin 56 projecting over periphery of disk 59, which is correspondingly beveled, it will ride up over and take a position on the other side of such pin 56, and so position itself that itslower orknife ill edge will at the proper instant of time raise up pin 56 out of the notch it rests in, and during this movement the pawl 61 is brought into position, in order to be ready to drop into one of the notches of disk 52, for the purpose of carrying forward the disk 52 and relocking it in position to show the next succeeding hour.
The operation is as follows: The snail 48 having pressed outward the arm 66, and such arm having rotated the disk 59 in direction shown by arrow in Fig. 10, the weight will be gradually raised, and the pin 6 1 be caused to assume a position on inner side of the pin 56, ready to elevate the latter by passing under it. The pawl 61 will also by this movement have been withdrawn from its notch and positioned so as to drop into the next succeeding notch, as bel'ore stated. As soon as the pin 68 drops off the largest diameter of snail ib the weight 71 will be caused to rotate the disk 59, (in direction of arrow on Fig. 11,) and the pin (Set will at same time elevate the locking pin 56 out of its notch, and allow the pawl 61. to drop into the notch. on disk 59, which it is positioned a little in advance of at that in stant, and thereby rotate the disk 52 the distance of one notch, at which point the lock pin 56 will arrest and lock it by dropping into the first notch rotated to a position under neath it. Such rotation will bring up to and expose in the opening 51 on the dial or faceplate the next consecutive hour-number of the disk-plate, which latter is rotated by the shalt 19, as before stated.
Fig. 10 represents the position of the parts last described j ust before the pin 64.- has passed to the inner side of locking-pin 56, and just before the end of pawl 61 has reached its position opposite the appropriate notch to engage with, when pin 56 is elevated and disengaged from its notch.
Fig. 11 shows the pin 61 as having just dis engaged the pin 56 from the notch, while the pawl 61 has dropped into the notch it has been rotated opposite to, which movements are practically simultaneous, to secure the rotation of the disk 52, so that the locking-pin 56 (the pin 6% having now passed away from its under side) shall take into the next succeeding notch, the pawl 61 carrying the disk 52 along until it is arrested and the hour-disk securely locked, the change of the hour being thereby indicated. The block 33 is pivoted to the pillar-plate 34,-, so that by depressing its rear arm, 72, it will draw to one side the arm 39, and permit one end of the letol'f bar 32 to pass between the pins 41 and 12, so as to change the figures representing the minutes and hours in the dial-openings. The block 83is,al"tersuch movement, returned to its normal position by the flat spring 73, one end of which is attached at its rear portion, and the other end presses against a pin, 74-, on the inner face of the rear pillar-plate. The tension put on the spring by depressing the arm 7 2 will automatically bring the block 38 into its normal position again on releasing such arm, a stud, 7:), acting as a limit to the upward movement of arm '72. The fractions of a minute, or the seconds, may be indicated by a secondhand, 76, which is placed on the end of the arbor of the fourth wheel, 1-1, of the time-train projecting through to the front of the dial or 'l'ace plate.
lily improvements are equally applicable to a movement in which it is desired to embody a striking mechanism or chimes mechanism, or both, as such features can be readily added thereto by means of appropriate trains of wheels in manner well known to those skilled in the art.
I claim 1. The combination, with a mainspriug or its equivalent, of two trains of wheels, one train controlled by the cscapenicnt and the other train for driving the minute and hour disks, with an intermediate minute let-oi'f bar, and vibrating cam-bar between said trains for letting oil" the last-named train at the proper intervals to drive around the minute and hour disks.
The combination, with the mainspring or its equivalent, ol" two trains of wheels, an intermediate minute let-oit' bar connecting such trains, minute let-oft disks, hour let-oll disk, and mechanism connected with and controlling the let-ol't of said disks.
The con'ibination, with the maii'ispring or its equivalent, ol two trains of wheels, an intermediate minute letoil" bar connecting such trains, minute let-oil" disks, hour let-ol't' disk, mechanism connected with and controlling the letoil" of said disks, and a dial or face plate in which are openings to expose at the proper interval of time figures indicating each minute of the hour and the full hour.
The arrangement of the arms 88 and 89 between the arbor of the fourth or last wheel of the tin'ie-train and the let-oil bar, the arm being constructed with abit'urcatcd end to grasp and be operated by a cam on such arbor, and the arm 39 constructed with. two pins, 11 and 42, on which the let-olt bar acts to let olt'i ntermittently the train driving the minutedisks, and thereby turn the said disks, so as to exhibit the number of minutes during the hour the time-piece has run.
