I TELLURIAN. No. 549,963. Patented Nov. 19, 1895.
UNITED STATES- :PATENT OFFICE.
CHARLES W. HOLBROOK, OF WINDSOR LOCKS, CONNECTICUT.
TELLURIIAN.
' SPECIFICATION forming part of Letters Patent N 0. 549,963, dated November 19, 1895.
Application filed March 9, 1893.
To all whom it may concern:
Be it known that I, CHARLES W. HOLBROOK, a citizen of the United States, and aresident of Windsor Looks, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Lunar Tellurians, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.-
My invention relates to apparatus to be used in connection with and as an aid to instruction in astronomy; and its object is to provide such an apparatus which shall embody means for illustrating in a graphic manner by means of globes the several phenomena attending the changes in the several positions of the earth and moon with reference to each other.
To this end my invention consists in the details of the several parts making up the apparatus as a whole, and in the combination of described, and pointed out in the claims.
Referring to the drawings, Figure 1 is a view in elevation of an apparatus embodying my improvement. Fig. 2 is atop or plan view of the same. Fig. 3 is a detail view in side elevation, showing a portion of one of the meridian rings with a globe mounted therein, a portion only of the globe being shown. Fig. 4 is a detail view of the opposite side of the ring. Fig. 5 is a detail view, in cross-section, through the ring. Fig. 6 is a detail view of the base and of a portion of the inner ends of the rotary arms and connected mechanism cut in vertical section.
In the accompanying drawings the letter a denotes a base, on which is mounted a sleeve a to which are secured the sections of a rotary arm'b. This arm extends on opposite sides of the sleeve a in the form shown herein, each arm having sleeves 19 arranged to rotate thereon, the sleeves being provided on their inner ends with cog-wheels b meshing with a fixed cog-wheel c on the base, and on their outer ends with cog-wheels b meshing with cog-wheels b 11 secured to vertical stems d at, this mechanism being used for astronomical purposes not herein set forth. A meridian ring 6 is borne on an upward extension secured to the base and projecting through the collar a and within this ring is supported an adjustable rin g f, to which is pivoted a ter- Serial No. 465,237. (No model.)
restrial globe. This construction is clearly shown in Figs. 3, 4, and 5 of the drawings.
On the base a is arranged a zodiacal circle a, and on this circle are designated the usual signs of the zodiac and periods of time, these being all properly marked, so that by referring to them to determine the position of the arm supporting the moon, to be hereinafter described, the proper relative position of the moon is shown-that is, for instance, when the arm overlies the sign at Virgo then the moon is shown in the opposite sign and in proper position as actually seen there by an observer from the surface of the earth.
Beneath the terrestrial globe, rigidly mounted on the central support secured to the base, is arranged a cam-plate j. The arm k, pivoted at its inner end to a collar is, attached to the standard that supports the globe, extends ra- 5 dially outward from the support, and by reasuch parts, as more particularly hereinafter son of its pivotal connection has a swinging movement up and down at the same time with the arm Z0 which engages cylinder b on the arm 17, causing the lunar arm 70 to be revolved about the central support with the arm I). The arm is has mounted thereon a roller 8, as shown in Fig. 3 of the drawings, this roller being in contact with the cam j and permitting a free movement of the arm is on said cam.
The moon Z, represented by a spherical body and secured to the outer end of the arm 10, not only revolves about the terrestrial globe, but rises up and down to a degree determined 'by the inclination and shape of the bearingsurface of the cam-plate j, preferably round, as shown in the drawings.
In order to properly show the phase of the moon, a hollow hemispherical cap m may be provided and tinted or colored black or otherwise marked to denote the shaded side of the moon. This cap is so made as to fit snugly upon the sphere representing the moon and is held thereon by frictional contact; but any desired means may be employed to hold it on the sphere while allowing a ready adjustment of the cap into any position needed to illustrate the lunar phenomena stated.
A further feature of the improvement is embodied in the particular construction of the supporting-ring, which contains within it an adjustable ring having a sliding motion within the supporting-ring and carrying the sockets for the poles of the globe, which is supported within the ring.
011 one side'of the ring there are graduations extending both ways from a horizontal plane to a vertical line passing through the support of the ring, usually numbered 0 at the sides and 90 at the top and bottom of the ring. This is the graduation of the ring; but 011 the other side is marked What I term a declination scale, which consists of graduations, the ninety-degree point of which is arranged twenty-three and onehalf degrees on one sideiof the ninety-degree mark on the opposite side of the ring, the object being to provide in this declination-ring a series of graduations that will enable the declination of any body supported away from the terrestrial globe to be at once determined by setting said globe with-its axes inclined to the horizontal plane.
I claim as my invention- 1. In combination with a base, a standard on the base, a terrestrial globe mounted on the standard, a cam plate secured to the base and overlying the rotary arm, the rotary arm supported by the standard, a lunar arm pivoted to a collar attached to the standard and overlying the cam plate, and having a downturned part in engagement with the rotary arm, and a globular body supported on the outer extremity of the lunar arm, all substantially as described.
2. In combination with abase, a standard on the base, a terrestrial globe mounted on the standard, a cam plate secured to the base and overlying the rotary arm, the rotary arm supported by the standard, a lunar arm pivoted to a collar attached to the standard and overlying the cam plate, and having a downturned part in engagement with the rotary arm, a roller supported on the lunar arm in contact with the cam plate, and a globular body supported on the outer extremity of the lunar arm, all substantially as described.
In combination with a base, a zodiacal circle delineated on the upper surface of the base, a standard on the base, a terrestrial globe mounted on the standard, a cam plate secured to the base and overlying a rotary arm,
the rotary arm supported by the standard, a
lunar arm pivotedto a collar attached to the standard and overlying the cam plate and having a downturned part in engagement with the rotary arm, and a globular body supported on the outer extremity of the arm, all substantially as described.
a. In combination with a base, a standard on the base, a zodiacal circle delineated on the base, a terrestrial globe mounted on the CHARLES \V. IIOTJBROOK.
