' vided With means for stretching a paper gore 1 along the meridian lines so that all meridians will be of substantially the same length to cause the finished paper gore to be 0f substantially theshape of thesector of the sphericalsurface to which it is to be applied.

In the specific form shown, I form numerous, closely-adj acentgrogves 6 along lines at right; angles to the meridian "lines; and, in order to have the lands or raised portionsbetween the .closelyi iadjacenti' grooves lower at theke dges.

than 'at the 'central portion, I preferably 12 j grind OK 'or otherwise remove the lands toward the edges as indicated-at' 7.-? This re--y inoval of the lands is preferablysubstantially progressively uniform fronithe central meridi'an toward '7 the edges so that along "the 1 -edge o'fthe, diemeinber le'the lands will-prac-r tically disappear; It shouldjbe' understood that the V lands 7 between adjacent grooves should be rather close together and of'but slightsdepth inorder' to avoidundue concentrated stretching 'ofthe paper 'gores;

Now, when the die'inember. 4 which is preferably made of metal has been provided with.

. the grooves' above described itis mounted on a press preferablyas the movablev member the complementary member :of' the press; The die member 2 may be made of heavy vcard- I board,jbakelite orvother substan'cei-nto'which thereof andia .coacting die memben 2. having a preferably smooth surface is mountediupon the ridges .on the die- 4 mayslightIy. force th paper'of the gores', and whichiwillpermit I the shaping of-thepaper gores to he efiee,

' tively accomplished. Itwouldbe possibleto form the-complementary :diememberZ with grooves-and lands complementary toi'those-of the die member 4;, but dueto the difficulty of always registering the die member's in eoin 'memial M -s e] flb 'i 'thati imy "One grooved 119 815; 4 is p t rable iwah -suoh=a single. formed die, I fhave' secured h h y s fe y re l t p i r is placed" upon one of the. die -memhers, and the tyvo thenf brought together withf the requisite foree; The grain of'thep'ap'er pref erably extends crosswise of thegorenthat V to say, along lines substantially at. right angles to the meridian-lines so that thellands' v 7 Ion the die member fl may separate toa very lsjlig htiextent the fibersofthe paper gore with: .outinjuriously stretchingthei fibers so as to mater-ially weaken the finished gore. "D'u efto the close' proximity of the lands on the diehf papeigoreis yeryslightly stretchedat a great' number, of closely adj ae'ent sections g which preferably extend substantially from 1 v end to end of the gore jandas soon as the dies. 2:"and 14 are separated,.the paper gore will curl "longitudinally substantially. into a 7 :sector of a sphere of intowhat may be termed orange peel formation substantiallyas shown inir igs. [With a properly "madefdie. all of the meridians of the, gore will be of substanwi l urth rmore beiseen, that tially the same length. The gores may then be very readily placed upon a base globe of the proper curvature to which they will substantiallyoonform and may be'sec'ured there- I 'to by an adhesive, 1

5. The method of forming pre-shaped paper gores for geographical globes and the i like, which comprises forming numerous, small, closely adjacent projections ona die member with the height of the projections decreasing gradually from the central zone thereof toward the edges, and then impressingthe die on a flat paper gore so as to cause the projections to stretch the paper gore and cause the inner meridian lines to be of substantially the same length and of substantially the same length as the edge meridian lines.

6. Apparatus for pre-shaping the paper sectors or gores for geographical globes and the like, which includes a die member having numerous, closely adj acent projections on one of the gore engaging surfaces thereof, the height of said projections being progressively greater along the inner meridian lines than along the outer meridian lines of the die.

7. Apparatus for pre-shaping paper gores or sectors for geographical globes andthe like, which includes a die member having numerous transverse'lands upon one of the gore engaging surfaces thereof, the height of said lands being progressively less toward the edges than at the center.

8. The method of pre-shaping a gore for a geographical globe or thelike, which consists in forminga sector/shaped flat strip of paper having oppositely curved edges to form the edge meridian lines of a. finished gore,

then applying pressure to that part of the sector between said meridian lines to form a large number of fine, closely arranged lnden- V tations on one surface of the sector to displace the fibers and to stretch said inner part lengthwise, thereby giving tothe finished gore an orange peel formation. 4 Y
