' The-presentinvention pertains; to geographical globe construction; and more particularly to a geographical globe mounting'means.
It has been th'e' a'lmost universal practice to make geographical. globe. supporting. meridians of either. the full or. half type by slush casting, die casting, orothercasting-processes. Some of these processesrequired' the use of special materials such aszinc alloys which are expensive and also brittle. The brittleness resulted in. a high percentage ofbreakage, both during manufacture of the globe and afterward as in shipment' and in use.
The presentinvention has for itsprimary ob- J'ects the provisionoia new andimprovedmerid ian made of metallic wire. More specifically, the meridian of the present. invention is preferthe upper and lower globe mounting means, the view being taken along the, linel -J of"Fig. 6;-

Another object of. the present invention is. the
provision of a new and improvedm eridian of. the type. described with novel globe. mounting means which. is detachably held. in assembled relation to the. meridian by reason. of, the inward force exerted thereon by the latter...
A further object of the present invention is the provisionoi new and improved meansfor. securing. the meridian to a supporting base.

The. illustrated' base is .madefofspun metal but. it may be made of other material'and may take'various forms. It isprovided with a longitudinalslot 16 (see Fig. 4) of a. width to receive the, meridian and. also a sleeve-like meridian mounting, mem- \ber l8 partially. surrounding the meridian and adapted to be securedto both the meridian and, base. The sleeve I8 is provided with an arcuate generally, channel-shaped upper portion ,20 encircling the inner portion of the meridian and also with a pair of opposed-.,arcuate flanges 22,
. the. upper surfaces ofwhich restagainstthe under' side of the top portion of the base M. This sleeve is passed upwardly through the. slot.- I'B and thereafter securedjd'irectly to the base, preferably as by welding. the. flanges to the. base. at two places. on opposite. sides, as indicated by the crossed-linesin.Figs.i3,and 4.
One. of, the important features of. the present invention resides. inthe. construction of the. meridian, ring l2.v The meridianring. is preferably made. of fiat steel wire formed into ar'cuate shape as byrolling). It should; be understood; how- .ever,, that other typeset metals can, be utilized aslong asthe metal. possessesv sufficient resiliency to perform the. functions requiredof. it and which will" be, described in greater detail hereinafter.
Also, it is not necessary that. the ring be made of flat wire, although this. is the preferred form.
The curvatureof the meridian is such that the oppositely located ends of the halimeridian exert anv inward force, -i. e., a force tending to compress the globe, .thereby to hold both the, globe mounting means, indicated generally, by. thereference characters 24, andthe globe in assembled relation relative to the meridian.
The meridian has secured to its peripheral portion a beading or molding Zliof generally channel shape, the sides of which are bent inwardly slightly as best indicated in Figs. 2 and 3. The molding may be readily applied to the-meridian as by welding the same thereto after the meridian has been properly formed. A preferred method of securing the molding to the meridian is to take a straight strip of molding and bend it as it is spot welded directly to the periphery of the meridian.
The curvature of the meridian is dependent primarily upon the diameter of the globe and also the length of the globe mounting means 24. In the construction illustrated in Fig. 1, the curvature of the meridian, when in a relaxed state and prior to the mounting of the globe therein, is such that the upper end lies at a point approximately corresponding to the top of the globe after the globe has been inserted therein. The construction of the meridian in this manner provide not only a meridian that can be constructed economically and is durable, but one which facilitates greatly the assembly of the globe, as will be de scribed in greater detail shortly.
The globe mounting means 24 are of identical construction and they are adapted detachably to be mounted on the meridian and also detachably to receive the globe. Each of the mounting means comprises a short pin 28 adapted to enter the diametrically opposite apertures in the globe. A
pair of pin embracing member 30 are secured.
as by spot welding, to the pin. The inner portions of the members 30 are bent around the pin, as indicated by the reference characters 32, to provide a more secure and better appearing construction and as shown best in Figs. 2 and 4. The outer ing at the top of the globe. A time dial 40 may be located between the globe and the mounting means as readily ascertainable from Fig. l. The top of the globe is then swung toward the meridian and the upper end of the meridian is lifted by suitable means to expand it to an extent suificient for it to pass over the top of the upper mounting means 24. When the meridian is thus expanded, the globe is moved to a position to align the opening in the mounting means with the meridian and the latter is then released so that it may be received in this opening with the pin 28 in registry with the notch 36 in the meridian.
In expanding the meridian, care should be exercised to avoid injury to the globe. .A suitable arrangement for expanding the meridian may comprise means extending between the lower portion of the globe and the meridian and other means adapted to be inserted immediately below the top portion of the meridian to force the two ends of the meridian apart. This enables force to be applied to the meridian alone and avoids danger of injury to the globe.
After the meridian globe and mounting means which results from the curvature of the meridian portions of the members 30 are flattened as indicated by the reference characters 34 and spaced apart a distance substantially equal to the width of the meridian l2 in order that the meridian may be received therein. The spacing is also such as to leave exposed the outer end of the pin 28.
The meridian is securely held in the mounting means and properly located therein by providing it with opposed slots or notches 36 of a shape to fit over the outer ends of the pins. 7 The construction thus provides an arrangement wherein the resiliency of the meridian is utilized to hold the globe mounting means and the globe in assembled relation to the meridian and likewise an arrangement that greatly facilitates the assembly of the globe.
In assembling the globe, the sleeve I8 is first secured to the base I 4 in the manner hereinbefore described. Thecurved meridian is inserted into the opening defined by the sleeve and the slotted portion of the base and then secured to the sleeve in suitable manner, as by spot welding the same thereto near the ends of the sleeve as indicated by the crossed lines in Fig. 4. The lower mounting means 24 is thereafter placed-on the meridian with the pin 28 in registry with the notch 36 in the meridian. The mounting means is thus detachably .held in place by reason of the registry of the pin and slot and also by the partial encirclement of the meridian by the fiat spaced apart portions 34. A washer 38 may then be placed over the pin to provide a suitable lower bearing for the globe.
The next step in the assembly is the placing 'of the globe on the lower mounting means. This is accomplished readily by holding the upper end of the globe away from the top of the meridian. While the upper end of the globe is thus held away from the meridian, the upper mounting means 24 may be readily inserted into the open- I being different from the curvature of the globe. The curvature may, of course, be varied to suit the globe diameter and the mounting means, but
it is preferred that the force exerted by the meridian not exceed a value that will unduly restrain rotation of the globe on the pins 28.
While it is preferred that the globe mounting means be removably mounted relative to the meridian, this is not necessary as the mounting means may be permanently secured to the meridian. A construction of this nature is illustrated in Fig. 5 wherein the meridian I2 has secured to it, as by welding, a pair of pin embracing members AZ-of a construction similar to the members 30 of the first embodiment. These members are likewise secured to the outer ends of a pin M located in abutting relationship to the meridian. I
In constructing a globe with the mounting means of Fig. 5, the mounting means are first secured to the meridian, then the globe is inserted over the lower mounting means, and, finally, the meridian is expanded to an extent sufficient for the upper pin to enter the opening at the top of the globe. Here, again, the curvature of the meridian should be such that rotation of the globe is not unduly restricted after assembly.
A further modification of the present invention is illustrated in Figs. 6, 7, and 8 to which reference will now be had. According to this modification, the meridian l2, which is constructed in a manner similar to that previously, described, is secured to the top-of a base by a sleeve-like member 52. The upper end 54 of this member is configured closely to encircle the meridian so that the two can be welded together. The lower portion of the sleeve is widened somewhat, as indicated by the reference characters 55 (see Fig. 8) to receive the molding 26' secured to the periphery of the meridian. The sleeve is also pro vided with a pair of oppositely extending arcuate flanges 58 resting directly on top of and welded to the base.
In this modification, the globe is mounted on the meridian in a somewhat different manner by means including a rod 60 extending through the globe and having its opposite ends extending into aeoaeev diametrically" opposite-- aperturd channel-like mountingmembers 62. portions 6'4- welded directly to the meridian and have their inner portions widened somewhat, as indicated by reference character 66% to enable and constructed in the manner previously de scribed; The mounting means- 62 are thensecured thereto at diametrically opposite points.
The meridian receiving sleeve 52- is then secured.
to the meridian ring and the assembly secured to the topofthe' base; The next step in theassembly is the'insertion of the-rod 'fi'flthrough the These members have globe and the" location of the globe" onthe lower meridian expanded in the manner previously described to enabl the upper mounting means to be located above the upper end of the rod. Finally, the expanding force is removed to permit the upper end of the meridian to move toward the'globe to bring theupper-mounting means over the upper end of the rod; as illustrated best in Fig. 7.
It may be noted that in this modification, and also in the modification of Fig. 5, where the mounting means are permanently secured to the meridian, the meridian may be so curved that neither it nor the mountin means are biased sufliciently' to bring'both' the mounting means into contact with the globe. In other. words, the
like encircling member H1 by a cammember l2.
The member T is provided witha'pair of substantiallycentrally located. projections or extensions 14 extending below the base 1:5 through a longitudinal slot 18. The cam i rotatably supported upon the extensions 14 by means of a shaft 80. The member is likewise provided with four oppositely extending flanged portions 82 at both sides thereof and also at both sides of the extensions l4 (only two of the flanges are shown), whereby the sleeve is secured to the base by welding the flanges to the latter.
In mounting the meridian on the base with this construction, the meridian mounting sleeve 10 is first Welded to the base and then the meridian is inserted through and finally the cam is operated to force the meridian upwardly into and against the portion of the sleeve encircling the meridian.
The principles of the present invention, while particularly adapted to'the construction of globes of the half meridian type, may also be utilized in the construction of a globe of the full meridian type. A globe of this character is illustrated in fragmentary form in Fig. 9. In this construction, the globe mounting means are identical withthe globe mounting means 24 of the first described embodiment. The meridian ring, however, is formed into a substantially circular shape. The ring is provided with anotch 84 located substantially centrally of the ends of the meridian and the abutting free ends are provided with half notches 85, which cooperate to form a complete notch for receiving the pin 28 of the upper flu mounting means: The: flattened portions 34 of theuppermounting means serveto'hold the abutting ends of" the meridian inplace and also give the assembly the appearance of a complete circul'armeridian". 7 i
In: assemblinga globe of the full" meridian type; the method of assembly oi-, thefirst described embodiment maybe followed, i. e;, the free ends of the meridian are lifted above the upper mounting meansfl and then allowed to move into-the mounting means either individually or simultaneousl'yi a While the present invention has-been described in connection with the specific details of preferred embodiments thereof, itshould be understood that these" details are not to be construed as limi'tativeof the invention except in solar as set forth in the accompanying claims.
