ROAD MAP.

Application ined June 30,

The present inventionrelates to improvements in highway maps which are adapted for use by drivers of motor vehicles. v'Ihe Construction of highway maps Aheretofore proposed does not lend itself to easy consultation Vof these -maps by the driver while the vehicle is under way. p `When occasion required the imfolding of these maps, either wholly orA in part, in order to examine the whole or a desired portion of the road ahead,

quired to manipulate the map. Obviously this requirement could be complied with only while the vehicle was'at a standstill and, therefore, involvedvr loss of considerable travel time. v v

Coming now to the present invention, the general object thereof isthe provision of a highway map having the general characteristics of Van end opening book of a size to be readily grasped by one hand and conveniently heldthereby, while in open position, so that thev various leaves may be manipullated to turn by the thumby ofthe hand in which the map is held.

` The above vand* vother objectsv are accomplished by instrumentalities pointed out in the following specification. f 1 defined in the claim. v l A satisfactory*embodiment of the invention is illustrated in the accompanying drawings formingpart ofthe specification and in which- Figure lis a in use.

Figure 2 is a detail side elevation of the same with one of the sides swung outwardly.

Figure 3 is a contracted plan view ofk the strip forming the subject matter of the present invention, but on a scale reduced from that shown in Figure 1.

Figure l is an edge view of the strip after the same has been folded and the sidesithereof fol-ded to provide the zigzag portions.

Figure 5 is aV vertical section through a portion of the map showingY a slightly modified form of the invention.

In carrying out'thepresent invention I provide an oblong strip 5 of paper or .any

other material that may be found suitable for the purpose of printing or otherwise impressing the characteristics of a map thereon. The width of sheety 5 is such that when the same is folded transversely, it is of a size to per- `strip 45.,

the inap is relatively large. Although I have 'shown an indication for one main highway on strip 6, it is obvious that insoine cases other indications of highways paralleling thel highway shown and in relatively close proxiinityv thereto may also be printed upon the Ity is to be noted that the printing of the'map is disposed on one surface only ofthe strip 5, and in order that any portion of the map may be readily inspected to the exclusion of other portions or sections, I

make 'use of a novel method of folding the strip. r f

In proceeding to fold the strip, I crease the same transversely along a line substantially midway between the opposite ends ofthe strip. This .resultsin providing side por- 'tion's 7 and 8.l Each side portion is then crease-d transversely along lines 9 spaced apart for equal distances throughout the `length of the side portion. The intervening port-ions between adjacent creases 9 constitute lsections l0. 'Ihe first formed or intermediate crease line isindicated by 11, and the subsequent crease lines 9 in each of the side portions 7 are so formed as to allow the outer surfaces of the adjacent sections 10 of each side portion to fold one upon the other.

Vith this construction the sections 10 of each side portion willextend along 'zigzag lines when the sections are extended. With f this construction it is also to be noted that when the sections l0 are folded along the lines 9 so that the outer faces of the sections bear one upon the other, the strip 5 is thereby folded into a size corresponding in area to any one of the sections 10 and, in this position of the parts, the folded sections function as the leaves of a book in that they may be successively turned. The free end portions of the :strip 5 are permanently joined together in any preferred manner as by an adhesive, and when so joined, constitutevone of the outer sides of the folded map.

`In that the present invention requires printing of the inap only on one face of the strip and the folding permits of observing successive portions of the mapsimply by" whole may be constructed as cheaply as any infill map having' only one surface thereof printed, and yet have the advantages of expensive method of printing successive sections of a map upon opposite pages of leaves and combininp` these into a book.

In thatI the device when folded is such as will readily lit within the pocket of a garment, it may be readily removed from the pocket by the use of one hand and when held upright and grasped between the lingers and the thumb, the leaves may be successively turned by the thumb until the required section of the map is visible. This property on the part of the inap is highly desirable in that the inap may be consulted from time to time to examine the route being followed by the motor vehicle and this without requiring that the vehicle be brought to a standstill, it being obvious that the driver may practically, under` all conditions, successfully control the steering wheel of the car by the use of one hand.

'lhe essential feature of the invention is the manner of folding the strip 5 and bringA ing)` the free ends together in the manner aforementioned, but it shall be understood that I am not to be limited to the printing upon one side only of the strip, as there are cases where the method of folding might be as set forth although the printing` may be performed upon both sides of the strip to render the map reversible. The form shown in Figure 5 of the drawing is an illustration of this slight modification.

In Figure 5 and in order that the strip shown thereincan be reversed, the ends 7 and 8EL are relatively free or in other Words, not gummed together. These ends and 8a are formed with holes 11 which register with each other. A case or holder is illustrated at 12 and same consists of a single piece of leather or other suitable well known material provided with spaced apart leads 13 and 14 and a cover lead or portion 15, the latter having a resilient fastening 16 to engage with a resilient liastcninfr 17 on the lead lll after the map strip is folded to come against the adjacent side of the lead 13. 'lhe lead 13 carries a resilient instelling;l 18 adapted to pass through the openings 11 and to engage with a mating;` fasteningon the inner face of the lead 'l-l. rlfhe case or holder 12 serves to permitthe map to be displayed when desired and when folded, said map is protected against being` unduly soiled when handled or carried in the por-liet and suine forms a neat and attractive means much resembling a card case for pocket use7 whereby the map is normally held in a very conipact manner where it will not be over bulky in the pocket of the user. l have described that a map constructed as set forth herein is desirable for pocket useA` but it shall be lurther understood that l do not wish to be limited in this respect because it can he made in any sizes and in view of the many advantages herein set forth, same may be made in sizes for wall purposes and parts thereof exposed for use in the marmer stated and yet same will be more ornamental than the well known normally exposed wall map employed heretofore. .ln dotted lines in Figure d, ll show how the case 12 can be adapted to the forni of map therein illustrated.

l claim:

A map comprising` a strip of flexible 1naterial havingl a route designated on one side thereof, .said strip being` equi-distantly creased crosswise alternately in opposite direct-ions to divide the strip into sections, adjacent pairs of sections being folded back to` baclr for constituting` leaves, the end seetions having their back surfaces secured to each other for conliningr one set of the allernate creases between the hinged edges of the two outermost leaves, said confined creases constituting` the back of the inap about which all of the leaves may be swung'.
