The framework of the ski binding'includes a .jl

pair of toe irons, generallyindicated at 24 and 25 (Figures 1, 3 and 4), and a base plate, 4generally indicated at 26. Toeirons 24 and 25 include base portions 13,4@ and 25a and vertical -flange portions. 24h and 25h. The base portions 24a and 25a. overlie the ski 21 and extendbeneath base -plate 26 to which they are connected o byy screws 28 and 29 (Figures 3 and 5). Screws 28 and 29 extend through transverse slots 30 #and v3I in base plate 2B, thus permitting movelirnent of toe irons 24 and 25 transversely with respect to the base plate. Toe irons 24 and 25 are connected to the ski 21 by two pairs of screws 32l and 33v which extend-through holes in base plate 26 and openings 34 and A35 in the base portions 24a and l250i kof the toe irons. These openings are of substantially greater width than *..the diameter of the shank of screws 32 and33 and thus permit angular as well as transverseadjustment of the toe irons with respect tol the -base plate 26.` Thus the` vertical ange portions 24h and 25h of the toe irons may be adjusted vto ,-iit bootswof different widths and shapes.

VWhen the toe irons-have been adjusted to iit the tapered toe portions .of the ski boots with l, which theyl are to beused, then screws 28, 29, 32, and 33- are tightened`,holding the toe irons ,.ingtheir adjusted positions.

To aid `in maintaining the toe irons intheir .-adjustedpositions, the front and rear corners 36,. 31, 38, and 39.(Figures 3 and 5)A of the base .w portions of each Vtoe iron areturned down vand `...sharpened ..Thus, .when screws32 -and 33,are

tightened, 'these lcorners are embedded into ski 21 'and prevent movement of the'toe ironswith r'e-y (Aspect vto theski.4

Baseplate 26 extends longitudinally of ski 21 thro'ughout thelength o f the ski. binding and is positioned over the base portions of toey irons 24 and I25 and a catch plate, generally indicated at 40.. .Catch 23 (Figures 1 and 3) is secured to catch plate 40 and extends upwardly through a., slot 26a in base plate 26 extendinglongitudinally thereof.A Catch plate 4I) has slots 42, 4,3,

, .44, and 45, therein extending longitudinally 1 thereof in alignment withholes in base plate 26 through which the screws 46 pass which connect .the rear end of the baseplate'to the ski. This rpermits plate ,4,0 and thus catch 23 to bead- ,justed longitudinally of the base plate 26 when screws 46 are` loosened so that catch 23 may be l- ,'adjusted to engage heel cable ZI when the ski "minding is unfastened (Figure 2). In addition toscrews 32 and 33, the center and forward j portions of baseplate 26 are connected to ski '26 `byscrews 41, 48 and 49 v(Figures and 4). Screws. aid in maintaining toe irons 24 and 25 lirr their adjusted positions by'creating tension tagainst the toetirons because there is a space between base plate 26 Vand the top of ski 2,1

feng-ages the upper leg `spring I 5.A` The lower leg Ib of spring I5 exforwardly and rearwardly of the base/ portions of the toe irons. This permits base plate 26 to be drawn downwardly with respect to the base portions of the toe irons so that it clamps the toe irons in their adjusted positions.

The toe of boot I 8 (Figure 1) is connected to the ski binding and thus to the ski by locking plates I and II which act through springs I5 and I6 toengage the weltof the `boot.` As locking platesY IIJ and I I are similar in construction, details of construction will be limited to locking "plate Ill (Figures 4 and 7). This locking plate ispivotally mounted upon the flange portion 24h of toe iron 24 by pivot pin I2 and. its lower edge I5a of U-shaped iiat ...ski boot. vWhen' the locking vplate IU is in a plate rIl! (Figure '7). locking position, corner I Ill)` (Figure/i) presses .locked position, corner Ic is positioned nearer the ski than corner Ib and thus the majorgripping action is .attained between cornerv IDc and `,thebaseportion 24b of toeiron 24. The rear end of the upper leg of spring I5 curves .upwardly to engage the rear portion of locking Thus, when plate I0 isv in downwardlyupon the rear -portion of spring leg y15a, causing the spring to press downwardly upon welts having a substantial variation in thickness.

lReferring to'Figure '1, it will be noted that the forward end 50a of serrated strip 50 curves uptom of the welt. To supplement the action of wardlyand that the strip is secured to toe iron 24 adjacent its rear end. As strip 50 is resilient, when locking plate I0 :presses the welt I1 of` the .ski bootagainst the strip, the forward end of the stripreacts to drive its teeth into the .bot-

the platev I0 and spring I5 in gripping the welt of the boot, the teeth on strip 50 slant forwardly,

`and thus,: when the locking plate is in locked `position-prevent the welt from moving rearwardly with respect to the ski.

.As pointed out hereinabove, locking plate II is substantially similar in` construction to locking plate I0. This plate is pivotally connected to flange 25h of toe iron 25 by pivot pin I3 (Figures l land 3) This plate coacts with a spring I6 similar in construction to spring I5 and a serrated 1strip 5I (Figure 5) to grip the welt on the lefthand side of the ski boot.l v

Plates I0 and II are moved into and outof v.locking position by resilientlever I4(Figure 4).

lLever I4 is lmade of spring -rod and the ends `of its rear portion, which are U-shaped, extend .downwardly into verticalV holes Id and II d (Figures 3, 4 and 5) in platesl I0 and II. The rear cured therein in any suitable manner, such as 'by punching a portion of each plate into annular recesses I4e and IIJ` (Figure 5) `formed in the *portions of lever I 4 extending downwardly in 'holes Ind and IId. This permits the rearends of lever i4 'to turn in the holes'in plates I0 and ll as the lever is raised and lowered and-th`us accommodate itself to `different angular positionsf` of theloc'king plates. Referring 'to Figure 4, the legs Maand I wardly andupwardly 4from plate Il! whenitisiin a closed position (Figure 4) toclear thetoeIpor-f tionpi the ski boot and thence extend downwardly toithe "foot of the U-shaped portionoi4 the" lever. The two Asidesoflever M then extend `forwardly to a juncturepoint` (Figure 3)-at theforward endof lever-I4. *Intermediate between the foot of the U-shaped portion oi lever wand"itsiorward end, a rod "52 yestends transverse'ly across the lever between `the 'two 'sides thereof* and is securedfthereto'- man3/suitable l1 manner, `such as by welding.

`liever I4 isso shaped longitudinally that when s thevlower edges of lockingpla'tes .Ill and -llenl gage" 'the welt of the boot, l.its forward end is still'pos'itioned a substantial distancezabove fthe ski. @Thus when it is moved downwardly so that bari52` is engaged by catch 2.2, lever I4 'exerts `a i resilient downward pressure in acounterclockwise direction, as viewed in Figure 4 upon plates` I0 and H and thus upon 'the welt oi the `ski boot. .i

Lever I4 is so constructed 'that itgives in two directions afterthe `locking plates' -engage the wel/trof the boot. The two portions of the lever which A"substantially parallel the ski (Figure d) i bend Vlongitudinally loft-the ski `and the `downso wardl-y vextending' sections of the U-shaped portion of the lever give toward the toe of theski boot.

of the ski boot. i

Catch" 22 is `pivotally Amounted by .a pivot `pin 54 which" extends transversely across and is con ne'cted to `apair of flanges 25o `and`26c (Figures 3 and e) extending upwardly from fthe sides of This results inachieving the resiliency of a lever of much greater overall length thanflever I4` `which is of `material aid in 'gripping the'welt e the forward end of base plate 26. With welts of` differentthicknesses, the `effective.length of le- Ver lli` becomes shorter Ior longer depending `on the"thickness of the welt being gripped and` thus bari 52 moves longitudinally/with respect `to Itho skrwhenit moves into latching positionwith .rew spect to catch 22. Thusto properly position catch 22, pivotpin 54 isadjustable longitudinallywith respect to flange portions Eib and28c. To imure that pivot pin 54 retains its adjusted position; it' is preferably :nadeln the formof a bolt having a square neck 554D. `The bolt extends through aligned longitudinal slots in ilanges 2819 and Zlicl The upper and lower edges of vone `or these slots areprovided with teeth55 ando@ (Figuresl and 8), opposed notches between these 'teeth being spaced'froin each other a distance equalto dia metrically opposed corners" on the neckportion 54h of pivot pin 54 (Figure 8). pivot pin 54 `is passed through the slots, the `neel:

Thus, `when the I portion of the pivot pinengages teeth, thus preiventing longitudinalinovement of the pivot pin with respect to the slots. The pivotfpinis pref erably held in positionV by a nut' 51 which" bears against a lock washer 5S andbase plate `ilange 2te.

Thus pivot pin 54 may be readily adjusted'lomgitudinally of the base plate to properly position catch 22 so that it engages bar 52.

vCatch 22 includes a forwardly extending tongue portion 22a which when the catch is in open position when it is unlatched because Iits rear end portion 22h is heavier thanthe forward portion ofthe catchmovin'g it inf aclockwise ."0 an open position is engaged by bar 52 (Figure 2) 1 as it moves downwardly. Catch 22 is held in an l direction, asv viewed in?` Figure 2,1, to the" position it occupies in Figure 2. When lever Ill` is moved" downwardly, bar l52 strikes the upper surface of; tongue portion 22a and throws catch 22 in fa catch` 22 pivots it in a clockwisev direction (Figure l4)` moving hook 22o out of the path of bar 52. Thus when pressure on the forward end of lever `I4 is released, bar 52 does not catch upon hook22c.

'as it does so, assisted by the action of springs I5 and I 6 on locking plates It and Il, the welt" is released. i

Punch platev 53 is so formed that the user may fasten or unfasten his ski bindings by using the end of his ski pole. Thus, the user does not haveto bend down on his knees in wet snow or slush 'whenever he desires to putv on or take off his skis. Referring to Figure 3, it will be noted that' there is a recess 22d (Figures 3 and 4) in *the rear portion 22h of catch 22.

This is pro-'- vided so that 'if snow orice prevents the catch from operating7 the user may open the catch by pressing downwardly on the rear portion of the `catch with his Vski pole thus freeing the bindingi" -Thus,` the user can` at all times remove his skis without touching his bindings with his hand, and

at times this is ofmaior importance such asafter an accident when it is not possible for theA skier to reach his bindings with his hands.

A pairof recesses Hic and I Ieare formed intheV forward upper portions of each of plates I0 and I The leg portions I lia and Iflo of lever I4' bridge these recesses and then extend through notches Illf and Ilf (Figures 3 and 4) formed in the upper surface of the forward portion of plates It and Il. Recesses Hic and IIe form openingsto permit atoe strap (it (Figures 2 and 3) tov bey mounted upon the legs Ita and Ido of levery I4.' It will be noted that strap 5t is moved downwardly `bylever It, and thus grips the toe of the When 'lever I4i (Figures 1 and 2) is moved3E downwardly -to a latched position, it acts throughY plates II) and Iland plates I9 and 20 (Figures 1 and 3)"tomove heel cable 2| forwardly into engagement with the heel Illa (Figure l) of bootI lfmlates I'S and"2 are pivotally connected to locking plates It and II by pivot pins 6I and 52 (Figures 2 and 7),

and`l25 by rivets 63 and (i4 which extend through arcuate slots 65 and 56 in toe iron fiange portions24lb rand 25o. lSlots 65 and 52 are embossed i outwardly and the head portions of pivot pins 53 anid suchas head portion Sila (Figure l0), of

these pins are flanged to lit the slots. A pair of linksllil' and 68 (Figures 2, 5 andi') are piv-W otal'ly connected to flange portions 24o and 25h (Figures 2 and 4|7) by pivotpins 5S and l!! which fare radially positioned with respect to arcuate slotsft `and 68. The other ends of links til' and are pivotally connected by pivot pinst and i 64 to plates L9 and 25%. Whenleverjifi ismoved towarda locked position, the? points B25 andffiS at which locking" plates `l t and |11 are `coniaetaii When pressure i is Lever Id is thus free to move up and` Plates I9 and 20 are also connected `to `the iiange portions of toe irons `2d to plates I9 and 20 move forwardly and downwardly as plates IU and II are pivotally connected to the toe irons 24 and 25 below the points ofvconnection 4between the two pairs of plates. At the same time because the heads of pivot pins 63 and 64 are following slots 65 and 66 which curve forwardly and downwardly and because of links 61 and 68, pivot pins 63 and 64 are moving forwardly. As pivot pins 6| and 63 are pivotally connected to plate I9 and pivot pins 62 and `6ft are pivotally connected to plate 20, plates I9 and 20 move forwardly with respect to ski 21 when lever I4 is moved to a locking position.

The heel cable 2l consists of a pair of rods 1I and 12 which are pivotally connected to plates I9 andZii. The forward end of each of these rods preferably extends outwardly (Figure 3) and is shaped to form wing portions lla and 12a (Figures 1 and '1). Holes 18 and 19 are provided in plates I9 and 20 which have upwardly and downwardly extending slots opening thereinto. When it is desired to attach a rod to a plate, it is vertically positioned with respect to the plate to which it is to be connected, the wing portions are passed through the slots, and then the rod is moved rearwardly and downwardly. When it is in a downward position, the wing portions 12a and 12b prevent the ends of therod from being drawn inwardly through the holes in the plate to which they are pivotally connected. 'Slots 18 and 19 are positioned adjacent the rear ends of the ange portions 24h and 25D of the toe irons and also slant forwardly (Figures 1 and 7), and the wing portions on rods 1I and 12 are longitudinally aligned with the rods. Thus to attach the heel cable, the plates I9 and 20 must be moved rearwardly or to an unfastened position as otherwise the heel cable cannot be slanted forwardly to align the wing portions of the rods with slots 18 and 19 because the rods 1I and 12 would strike the toe irons and locking plates I and II. Thus when the skis are removed, if the binding is placed in a fastened position, the heel cablev cannot become accidentally disconnected from the binding'.

The rear portion of the heel cable is in the form of a coil spring 13 to which rods 1I' and 12 are connected by a pair of metal fittings 14 and 15 (Figures 3 and 6). These metal fittings are similar in construction and each is threaded on its Vexterior surface so that each fitting may be threaded into an end of spring 13. A thread hole, similar to hole 15a (Figure 6), extends through each of ttings 14 and 15 and the rear ends of rods 1| and 12 are threaded into these holes. When it is desired to adjust the heel cable with respect to the heel of a boot, spring 13 is adjusted toward and fromA the heel by disconnecting rods 1I and 12 from plates I9 and 2|) and then turning rods 1I and 12 into or out of ttings 14 and 15. After the adjustment is made, rods 1I and 12 are again connected to plates I9 and 2B as described hereinabove.

To permit the heel cable to exert a downward pressure upon the heel, if such pressure is desired, plates I9 and 20 have holes 1B and 11 (Fig-v ures 1 and '1) therein positioned rearwardly and downwardly from holes 18 and 19 (Figures 2 and 7). Rods 1I and 12 may be connected to holes 16 and 11, and then when lever I4 is moved to a latched position, the heel cable 2| exerts a downward pull upon the heel of the boot.

When the lever I4 moves upwardly, it moves plates I9 and 20 rearwardly. Because of the rigidity of rods 1I and 12 the spring portion 13 of cable 2| is moved beneath catch 23 (Figure 2). When the heel cable is so positioned as the grip upon the welt of the boot has been released, theV heel may be raised and then the boot withdrawn rearwardly out of the ski binding.

Thus, in operation, when it is desired to fasten l the ski binding, the toe is inserted into the binding so that the upper legs of springs I5 and I'G overlie the welt on the opposite sides of the toe of the boot (Figure 5). Next the heel portion of the boot is placed down in contact with base plate 26 and then lever I4 is moved downwardly.

As the lever moves downwardly the heel cable A iirst moves the ski boot forwardly into proper position between the toe irons and then locking plates I0 and I I exert a pressure downwardly upon the upper legs of springs I5 and IS rmly gripping the welt between the springs and serrated strips 5c and-5|. It will be noted that the hook portion i 23a of catch 23 is positioned above the ski, and thus when the cable leaves catch 23, it moves into engagement with the groove in the heel of the ski boot. This eliminates the necessity of Y raising the heel cable by hand each time thel binding' is fastened and together with catch 22 makes a binding whichrnay be operated simply Y by `pressing downwardly on punch plate 53 with a skipole. At the same time heel cable 2| moves forwardly (Figure 1) sothat coil spring 13 resiliently engages the heel 18a of the ski boot. Then lever I4 is bent downwardly so that bar 52 (Figure 4) actuates catch 22 to latch lever I4 in a downward position. v

To release a ski boot from the ski binding, punch 53 is pressed downwardly. This permits catch 22 to pivot to an unlatched position so that lever I4 is free to move upwardly.v As lever I4 moves upwardly, it moves plates I I) and I'I in a clockwise direction releasing pressure on the upper legs of springs I5 and I6 and acting through plates I9 and 29 to move the heel cable 2| rearwardly into engagement with catch 23. At'this time the ski boot may be removed from the ski binding. It will be noted that punch plate 53 (Figures 2 and 4) has a downwardly extending portion 53a. which protects catch 22 so that snow or other objects cannot pass beneath the forward end of lever I4 to move catch 22 to an unlatched position. It also prevents any foreign objects, such as the ring of a ski pole or a branch of a tree from being caught under the end of lever I4. f

The ski binding shown is so constructed that it may be adjusted to fit any size ski boot. As described hereinabove, toe irons 24 and 25 (Figure 3) may be moved transversely with respect to the ski and their angular position may also be varied so that they iit the toe portion of the boot. As

springs I5 and I6 and all of the other mechanism l Vout of the metal fittings 14 and 15 secured to the forward ends of coil spring 13. After they have been adjusted, they are again connected to plates I9 and 20 in the high or low position depending on the directionV the user prefers to have pull exerted upon the heel of his ski boot.
