This invention isla novel improvement in folding skisn which the ski isvprovided with ihinged sections :which will permitA the ski to begreadily and conveniently folded insuchmanner'that the front and rear sections when foldedl will be disposed substantiallyvparallel, vand folded ski rbeing amoroximatelyv half the length of the normal ski.` Ordinary skis are 'generally'aboutlsevenfeet in length; and the inconvenienceV of.r transporting same because of their length is well known, said lengthlpreventing same from being carried inside the usual automobile body, and rendering Vsame inconvenient for shipping by train or thellike due to the fact that they require a special rack, or must be voratedy to prevent, breakage,

Theprincipal objects of my'. invention are to provide aski having a` hinge 4of minimum weight, and of inexpensive construction, which hinge isA simple to operate since the. necessity of using a wrench, screwdriver, or other 'tool' in order to make or break the lock in folding and 'unfolding the .ski isnot required; also a hinged ski inwhich` the two hinged sectionsV thereof cannot come apart .in that no parts of the hinge kitself mayv become disassembled; alsof to provide a hingefor -a sk'iwhich wllnot reduce the strength of theV ski, and 'a hinge which therefore maybedisposed at or near thecenter ofthe ski Without sacrificing the' strength of thejvski,v vthefvv'eakest partV ofthe normal sk'being` at a' point someidis tance ahead'of the center of the ski also topro-V vide a ski hinge and lock in which thepfront andl rear niembersof the hinge willbe held inrigid alignment wth`respect to eachother when the members are locked such position; to provide aski hinge in Awhich the lockjis adapted `to take up any playy or, looseness between-the members thereof which may arise due to wear orto 'inanui 'alcturingtolerance; Aandfurtlier to provide "a hinged ski in vvhioh'thefrunning surface thereofkv constantlyremainsmooth.` 1

I will explain the invention lwith reference to the accompanying drawings, which illustrate oney practical embodilnentthereofto .enable others familiar with the art toadopt and usethe same;`

and'vvill Vsummarize Yin the claims, the novel feav tures or construction, and novel combinations of parts, for `which'protection 4is desired` Insaid drawings: f

The inner end-sof thefwebs l3 and! are also beveledzas at 3a,4a lparallel withand opposite thelbeveied ends la, 2a of the.shann-elmemin anch theski provided 1 with a front section fF, and -a rear :sectionit,V which in normal position are in .abutting ,rela-gbeing perforated to receive bolts or rivets 6 and I in double shear which transiix the Webs of the channel members I and 2 and the additional Webs 3 and 4, thev endsof the bolts or rivets being enlarged to prevent same from dropping or backing out of their holes in the channels and webs. The

lower anges of channel members I and 2 are4 slotted inwardly as at 8 (Fig. 2) to points beyond the bolts or rivets 6 and I to permit link 5 to swing freely on its pivots 6 and .'I. `Link 5 thus permits the channel member luto be swung down-- wardly, around and under the ychannel member 2,.

as indicated in Fig. 4. Y,

If desired, an aligning tongue 9 may be secured between the web of channel "I and the additional web 3 thereof adjacent the upper ange of channel I, said tongue being adapted to enter between the web of channel 2 and its additional web 4 when the members I and 2 are in normal aligned position. However, the tongue 9 is not essential and may be omitted.

The upper flange of the channel member 2 adjacent the beveled end Zais somewhat widened as at 2c, and carries oniits upper surface a wedgeshaped plate I thickest at its outer end, said plate I Il having a'longitudinalslot Illa therein extending inwardly from its outer end. Welded on the additional web 3 of the channel member I is a bolt II, the axis of whichcrosses the line of bevel of theends Ia and 3a of channel member I, `said bolt extending above the upper ange of thechannel I and being adapted to enter the slot Illa. in beveled plate I0 of channel 2, said bolt II carrying a thumb or Wing nut I2 or the like, adapted when the parts are in normal position 'shown in Figs. land i to be screwed down without the aid of a wrench or other tool to seat upon the wedge plate I0 and thereby lock the channel members I, 2 in aligned position, the base of nut I2 seating squarely upon the top, ofthe bevel plate III. The outer end of boltfll is enlargedto prevent nut` I2 from'becoming disengaged with theI bolt. By the above construction', the bolt II welded to the additional web 3 and carrying the wing nut I2, and the slotted plate I0, constitute the lock of the hinge. v

' Eachhinge unit is secured onthe side edge of the ski sections F and R by screws rI3 or the like,- three being shown oneach member I and2, pass-V ingthrough holes provided therefor in the webs of the channels I "and 2 and through the additional webs 3 and l. The bosom ofthe channel members I and 2 snugly receive thesides ofthe ski sections F andf'R which-may beV recessed to receive the channel members I and 2, so that the outer faces of the; channel angesand web lie flush with'the tops, sides and bottoms of the ski sections;'and as previously stated the hinge members aresomounted that the beveled ends of the channels I .and 2. Vare disposed directly opposite the beveled eiidFf and R of skiisections F and R. In'order tofoldthe ski,'the wing nuts I2 must be `suflicientlvi unscrewed or loosened, and then the front sectionlF and channel' members of the hinge'are' free to rotate about rivet or pin 6. When thus rotated approximately 90 or into the position shown in dot-and-dash lines in Fig.'4, fui-ther rotation can take place about. pin. 1. or

into position shown in dotted lines in Fig. 4; and the corner of channel I will clear the bottom of channel 2. Correspondingly, when the hinge is straightened out, one quarter turn must first take place around pin 'I and then a second quarter turn about pin 6, or until the hinge is straight.

Y mits the ski to fold; and second, it makes the lock' possible, as that when the wing nut I2 is tightened, the front and rear halves of the ski andv hinge are pulled together, and the front halves tend to slide upwardly with respect to the rear valves until they are in contact along the full length of the diagonal cut, thus holding the front and rear halves in alignment at all times. Also, as the pinsA 6 and 'I vor links 5 may wear somewhat due to use, the play will be taken up by the front halves sliding up a little further than normally, but the correct alignment of the ski sections will still be maintained. Since the wing nut lock is disposed on the upper surface of the hinge, the lock does not interfere in any way with the installation of the ski boot binding.

I do not limit my invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.
