llclaims.
My invention relates to globe chronometers. Important objects of the invention are: to provide an accurate timepiece whereby the various times throughout the globe may be readily ascertained; to provide means whereby the face of the globe is not marred or obstructed; to provide means whereby there are no moving parts within the globe, leaving its surface free for perfect and unobstructed illumination from the interior;
to provide means whereby the globe may be readily removed from its support for access to the bulb therein; to provide means whereby the globe may be turned for adJusting the same with respect to a given pointer; to provide means whereby the traveling time indicating element may be manually adjusted with respect to the globe and pointer; to provide means whereby the globe is supported upon its axis of rotation having the proper inclination; toprovide means for 2 driving the time indicating element, which driving means is positioned exteriorly of the globe for convenient access in adjustments; and to provide apparatus of the above mentioned character which is extremely simple in construction and reliable in operation.
In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a perspective view of a globe chronometer embodying my invention,
Figure 2 is a side elevation of the same,
Figure 3 is a central vertical section through the same,
Figure 4 is an exploded perspective view of the various elements of the device,
Figure 5 is a fragmentary plan view of the globe and pointer, and
Figure 6 is a diagrammatic view of the circuit included in the device.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of 'my invention, the numeral I. designates a hollow base, having a chamber II, the lower open end of which is covered by a removable plate i2. Mounted within this chamber II is clock works I3, preferably electrically operated. Current is supplied to this electrically operated clock works by wires l4 and I4, and a switch it, of
the oil and on type is connected in the circuit, and is opened and clowd by a rotary knob ll, arranged exteriorly of the base Ill. The wire it is connected with a wire a, having the switch It connected therein, and the wire Ila is connected with one terminal of the electric bulb socket II, the other terminal of which is connected with a wire 2|, connected with the wire it. A wire II is connected with the pole of a motor I! of the clock works and the opposite end of the wire it is connected with the wire 5- i. The opposite pole of this motor is connected with a wire 21', connected with wire ll. Arranged above and centrally of the top of the base II is a curved bracket or support 20, which is rigidly attached to the base by a screw 2i or 10 the like, arranged centrally of the top of the base. The socket I! is rigidly attached to the lower end portion of the curved bracket or support 20, and the wires a and 20' pass through an' opening 22 in this bracket or support. The 1:; socket I8 is elongated, cylindrical, and its outer surface is preferably smooth. The socket I8 is inclined with respect to the perpendicular, corresponding to the inclination of the axis of the The numeral 23 designates a globe, having an accurate map of the world formed thereon embodying the various continents, oceans, etc., and the meridian lines 24 which are designated in the usual manner. This globe is preferably light 25 transmitting and may be translucent or transparent. The globe is preferably provided at its north pole with a knob 25, for convenience of handling. Arranged within the globe 23, at its south pole, is a cylindrical sleeve 20, rigidly attached thereto, and this sleeve is removably mounted upon the socket II and is free to turn thereon. The downward movement of the sleeve 28 is limited by the base or projection 21 of the socket ii. The sleeve 26 is also adapted to be 35 passed over an electric bulb 28, mounted within the socket II, with its terminals in contact with the terminals of the sockets, as is well known. The diameter of this bulb does not exceed the diameter of the socket ll, so that the sleeve may 40 be passed over the bulb, as stated. The longitudinal axis of the socket II is in alignment with the north and south poles of the globe and this longitudinal axis is inclined to coincide with the axis of rotation of the globe, which is inclined to 45 correspond to the actual inclination of the axis of rotation of, the earth. Particular attention is called to the fact that there are no operating or driving parts within the globe 23, whereby the globe may be illuminated interiorly, in the uniso form and proper manner. The ready removal of the globe from the socket ll renders it convenient to have access to the bulb 20, to renew the same, when desired.
Preferably arranged at the equator of the globe it is arace band or stationary supporting element 29, which is preferably annular and slightly larger in diameter than the globe at the equator, so that there is a space between the same. This race band has its plane parallel with the plane of the globe at the equator, and the plane oi" the race band 2d ls perpendicular to the central longitudinal axis of the socket it. race band has its upper surface grooved to term an annular recess tt, receiving an ular rotatable equatorial ring gear hi, or te. indicating element. This ring gear is provided with gear teeth ti upon its outer side or periphery and the ring gear is free to turn within the recess tit and is guided by the race hand. The interior diameter of the ring gear it is also slightly larger than the diameter of the globe at the equator, to provide a space between the same. The ring gear rests upon horizontally rotating rollers dd, rotatably mounted upon pins til, fixed to the race band and arranged within the recess til. .ilny other suitable form of anti-friction means may be employed for supporting the'ring gear ti, if desired. at the high end of the race band "it is a bracket die, rigidly secured thereto, having a horizontal arm til, which overhangs the ring gear ti. "this bracket carries'an upwardly pro- ,iecting pointer M. a bracket th is arranged at the low portion of the ring gear ti and has a horizontal lip tt overhanging the ring gear, and the bracket db, curved support or bracket tilt, and race band iii are all rigidly connected by means oi screws d'i. These screws extend through openings tit and it and have screw threaded engagement within openings lit. The race band iii engages within a recess ti providing a shoulder it, engaging the bottom of the race hand. The brackets Etta and it are diametrically oppositely arranged and hold the ring gear against upward displment.
The ring gear is therefore rotatably supported at the equator oi the globe in a plane parallel with the plane ofthe equator and the plane of the ring gear is at a right angle to the central longitudinal axis oi the socket it. lit is thus seen that the globe may be turned with relation to the race hand it and the ring gear may be turned with relation to the race hand and also with relation to the globe. The ring gear or time indicating element is provided with two sets oi pins or points ltach set of pins or points carry numerals the running from i to 12 inclusive and increasing in value in the same direction and the l of one set of nerals being arranged neat to the "12 ot the other set. One set oi numerals is black to designate the P. M. time and the other set of numerals white to designate the A. ill. time. the l of the ll. numerah is arranged next to the i2 oi the P. M. numerals, and vice versa. The nerals in each set are oi course equi-distantly spaced and designate hours and they divide the ring gear into 2d hour spaces of equal length. The spaces between each pair of numerals are further divided by pins 36, designating time intervals of 15 minutes, each hour being divided into four it minute inmrvals, although other time intervals may be used for each hour. The pointer t l is arrangedto coact with the numerals the and points 36, as is obvious.
The numeral M designates a small pinion or gear, operating beneath the lip db and within recesses 45 and 46, Figure d, and this pinion is in permanent mesh with the gear teeth lit. the
pinion or gear M; is rigidly mounted upon the notable upper end of an upwardly projecting inclined drive shaft til, which is parallel with the central longitudinal axis ofthe socket iii. The upper portion of this drive shaft is iournaled in a hearing tt formed in the upper end of the support 20.
the clock works, the shaft may be turned by cans of a wheel or knob hi rigidly secured thereto, without driving the clock works. The ratio oi the gear it with respect to the ring gear di, and the speed oi rotation of the rotatable part tilt of the clock works are so adjusted that the gear M will turn. the ring gear ti for a complete rotation for each 2d hours.
".lhe operation of the apparatus is as follows.
if the apparatus is being used in New York city, the globe would he turned until the '75 W. meridian was near the pointer, since New York city has a longitude of 7d W. lihe correct time at New York being for example 3:00 P. M., the
operator would turn the knob hi to bring the ring gear to such aposition that the white 3 carried by the ring gear would be opposite the pointer, and as the clock works continue to operate, the ring gear would turn clockwise indicating the change in time in New York city. To ascertain the time at any other place in the world, the longitude of such Place is located and then the black or white number tile next to the meridian line which is adjacent to such ascertained place, will indicate the time at such place. For instance, if it is 3:00 P. M. in New York city it will be found to be about t:l5 P. M. at Paris, France, and about 62th A. M. at Sydney, Australia.
It is to be understood that the dorm oi my invention herewith shown and described is to be taken as a preferred embodiment of the same and the various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
