ROAD MAP HOLDER Filed Oct. 13, 1927 fiufen'ro; lf l'lZz'am M72227 Patented Sept. 17, 1929 UNITED STATES PATENT oFFlcE.

ROAD -1VIAP HOLDER Application filed October 13, 1927. Serial No. 225,904. i

This invention relates to improvements in road map holders and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The primary object of the invention is to provide a small compact device, easily secured in place in an automobile convenient for the driver thereof, to hold a strip like road map which may be readily withdrawn for inspection of any portion thereof and which when released is quickly rolled up in the device to be out of the way but ready at all times for future withdrawals and inspection.

A further object of the invention is to provide a device of this kind whereby different maps in strip form may be readily substituted the one for the other occasion demands.

Another object of the invention is to pro- 2 vide a device of the kind described which may be readily produced and sold at a reasonable price and which consists of but a few parts strong and rugged inthemselves, and which cannot readily get out of order.

In the drawing: 1

Fig. 1 is a perspective view of the device as when supported upon a part of an automobile.

Fig. 2 is a longitudinal sectional view through the device, on an enlarged scale as taken on the line 2-2 of Fig. 3.

tional views through the device as taken on the line 83 and i4 respectively of Fig; 2.

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawings, myimproved road map holder includes a hollow cylindrical non-rotative body member 1 preferably arranged in a horizontal plane with a frictional engaging cap or head 22 at each end and having a longitudinal slit 01' slot 3 extending the full length thereof along one side. Arranged concentrically within the hollow body is a nonrotative shaft 4, having threaded end extensions 55 which project through and beyond the respective caps or heads 2 to receive a knurled nut 6 by which the various parts are secured in the desired relation. As best shown in Fig. 2 and for the sake of lightness, I make the shaft 4 tubular and make the ex- Figs. 3 and 4 are transverse vertical sectensions 5-5 integral with plugs 7 which havea tight fit in the ends of thetube of said shaft. i

Fixed to one end of the shaft 4 and spaced a short distance from the associated cap or, head 2, is a collar 8 and journalled onthe other end of said shaft adjacent the associated cap or head 2 is a second collar9 which ineludes anannular shoulder 10 between its ends. A helicalspring 11 surrounds the shaft l and said spring is secured at one end to the collar 8 and at its otherendto thecollar 9. A tubular shell or sleeve 12 has a snug frictional fit at one end upon the annular shoulder 10 of the collar 9 and .carries'a spacing ring 13 at its other end which is journalled on the shaft 4 at a point between the collar 8 fixed; thereon and the associaflad cap or head 2. Frictionallyengagcd on said tubular shell but removable therefrom is a second tubular shell or sleeve 14 upon which a stripof flexiblematerial 15 hereinafter termed a map strip is wound, one end of said map strip being secured; to said sleeve'while the other end which extends through the slit 3 in the casing l has a reinforcedthickened portion 16 thereon to prevent it from being drawn into the casing in the winding up of the map strip. 1 H

The device above described may be attached in a number of different manners to a'lixed partof anautomobile convenient for the driver thereof. .I find one convenient mannor is to provide a holder comprising an elongated plate 17 having on one side thereof, U-shapech'Spring clamping arms 17 at its ends to receive theannular portions of the heads2 of the casing. andlhavingon the other side thereof, suction cups 18 by which the holder may be removably attached to the windshield orinstrumentboard of an automobile. .1 i 1 Assume that an automobile is travelling along a road whichis shown upon the map strip. Should the driver become confused as to his location upon this road, he grasps the thickened portion 16ofthe map strip and pulls upon the same until there is disclosed thereby, certain indicia by which he .determineshis position by comparison with strip fixed at one end to said second sleeve land marks along the road such as villages,

and having its other end pro ect1ng through bridges or certain buildings or the like. In pulling upon the map strip the sleeves 14 and 12 are rotated and as the shell 12 has a friction fit upon the collar 9 said collar is rotated. As one end of the spring 11 is fixed to said collar, it is apparent that said spring will be wound up from that end and placed under a tension so that as soon as a proper location has been determined from an inspection of the map strip, the same is released and the tension of the spring will immediately wind it up upon the sleeve 14.

Should it be desired to changethe map for another one as when in following trans-con tinental highways, the device is removed from the holder and the nuts 6 removed after which the caps or heads are removed. The sleeve 1 may now be slipped endwise of the sleeve 12 and another sleeve 14 containing another sectional map of the highway is substituted for the first, after which the parts removed are re-assembled as is apparent.

By making the sleeve 14: removable from the sleeve 12, it is apparent that it is not necessary to remove the sleeve 12 from the casing, which might result in a disarrangement of the spring and collars and besides much time and annoyance is saved in making the change.

While in describing my invention, I have referred in detail to the form, arrangement and construction of the various parts thereof, the same is to be considered as by way of illustration only except as may be pointed out in the appended claims.

I claim as my invention:

1. A device of the kind described emboc yin therein, an open ended tubular casing having aslit therein, caps closing the ends of said casing and one of which is removable therefrom, a non-rotative shaft in said casing having a part extending through said removable cap, means on said shaft part for securing the removable cap thereto, a sleeve surrounding said shaft and journalled with respect thereto, a spring arranged between andfixed at its ends to said shaft and sleeve respectively and a map strip operatively engaged at one end with said sleeve and at its other and projecting through said slit in the casing.

2. A device of the kind described embodying therein, an open ended tubular casing having a slit therein, caps closing the ends of said casing and one of which is removable therefrom, a non-rotative shaft in said casing having a part extending through said removable cap, meanson said shaft part for securing the removable cap thereto, a sleeve surrounding said shaft and journalled with respect thereto, a spring arranged between and fixed at its ends to said shaft and sleeve respectively, a second sleeve frictionally engaged with said first sleeve to be rotative with but removable therefrom and a map said slit in the casing.

In testimony whereof, I have hereunto set my hand, this 10th day of October, 1927.

WILLIAM WINTER.
