SKEE-STIRRUR Specification of Letters Patent.

Patented June 23, 1908 i Application led March 9, 1908. Serial No.' 420,016.

To all whom 'it may concern:

Be it known that I, CARL NORDLANDER, asubject of the King .of Sweden, residing at Norway, in the county of Dickinson and State of Michigan, have invented certain new and useful Improvements in Skee-Stirrups; Y and I do declare the following to be a full,-

' clear, and exact description of the invention,

such as will enable others skilled in the-art to which it appertains to make and use the same. This invention relates to skee stirrups and especially to that class of devices shown in my Patent No. 870,741, of Nov. 12th, 1907.

The object of the present invention is to provide a device of this character which will prevent serious results from accidental falls, it being the articular object to release the user of the s ee. A further object of the invention is the provision of novel means for holding the ankle strap, to the heel yplate so as to allow disengagement thereof upon undue strain being exerted thereon, and means to accentuate the action when the foot of the user assumes such a position with relation to the runner that a fall is unavoidable.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts', as will be more fully described and partlcularly pointed out in the appended dirimir dr E n t e accom anying awings i e 1 is a perspective viiiw; Fig. 2 alo 'tudlarl section; Fig. 8 a top plan view part y in section; A

Fig. 4 is a fragmentary diagonal section taken on the line 4-4 of Fig. 1. i

Referring more especially to the drawings, 1 represents the skee runner upon the top of which adjacent its center is secured in any suitable manner Vthe stirrup plate 2. At the forward end of the stirrup plate I secure by rivets or otherwise thetoe plate 3 ha the toe strap 4 secured thereto by an a 'ary plate 5j arranged beneath the toe plate and aving pivoted thereto the rearwardly -extending shank plate 6. This plate extends rearwardly for some distance from thetoe plate and is provided with a spring arm 7 the hee plate to a point adjacent the counter plate 12 so that the heel plate and its associated Icounter may have side adjustment. with respect to the distance to or from the J toe plate and its associated toe strap. This is done in order to adapt the device for diierent sized shoes. Secured to the left hand ear 13 of the'plate 12 is the strap buckle 14 which holds the ankle stra 15 1n adjusted position. The opposite en of the strap has secured thereto a pair of plates 16 and 17 ex- 65 some distance beyond the strap paralle to each other so as t0 overlie the ten right ear 18 of the counter plate.y The lower or. lnncr plate is perfectly plane throughout its length but the upper plate 17 has stamped 70 up out of its body a curvilinear arm which forms a cam surface ada ted to be engaged by a conical stud 20 carried upon the ear 18.

:A stud clamping member 21 surrounds the l plates 16 and 17 and is adapted to slide there- 75 oversto increase their pressure upon the ear 18 and make the disengagement of the up er plate 17 with the conical lug more or ess dilicult as the case may require.

This device hassuihcient holdupon the counter plate t0 prevent any disengagement, except where extreme conditions occur and strains beyond the normal are brought to bear upon the strap.

. It will be seen that when the heel of the wearer is held upon the heel plate by the strap 15 that the shank late will be held in adjustable engagement t erewith by reason of thev heel engaging the spring arm and holding its contact stud in engagement with the a ertures 10 of the heel plate. The heel `prate being free of the mounting plate 2 is ce to move with the shank late as it pivots u (in its hinge connection with the auxiliary p a e 5. Y

When the operator or user of the, skee after a jump or a fall has the toe of the skee runner engage the ground rior to the rest of the runner, the heel of t e wearer leaves the runner and rises with the shank late on its I pivot. At this time it is almost impossible to avoid a fall and disengagement of the foot from the stirru is absolutely necessary. ln order to provi e for such accidents, I extend the heel of the toe plate 3 a suitable distance 105 beyond the hinge connection oii the shank late with the auxiliary plate so that it overies the same in position to engage an upstanding stud 22 which stops the upward movement of the shank plate and thereby quiring a more extendedexplanation.

throws additional strain u on the strap. This additional strain is su cient to disengage the plates from the ear 18 of the counter and thus releasing the operators foot therefrom. The foot readily sli s out of the toe strap when thus disengage and the user is free to take any movement he may see fit in respect to the position of the runners.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention Will be readily understood Without re- Varlous changes in the orm, proportion and the minor details of construction may be resorted to Without departing from the principle or sacricin any of the advantage .of the invention, as eined in the appen claims.

I claim as my invention:-. 1. In a skee stirrup a toe plate and a heel plate, bmeans to secure the foot to the toe plate, means disengageable from the heel plate upon an excess strainfor securing the heel to said heel plate and means to adjust said heel isecuring means.

2. In a skee stlrrup, a toe plate and a heel plate, a toe stra for securing the foot to the toe plate, 'a`hee plate and a pivoted shank plate adjustably connected to the heel plate.

3. In a skee stirrup, a front Iplate, means for securing the foot of the wearer thereto, an auxiliary plate secured to the other side of the toe plate, a heel plate, means for securing the Wearers foot to the heel plate said means being disengageable from the heel plate upon an excess strain being applied thereto, and means carried by the shank plate and acting in conjunction with the toe plate to accentuate the strain When said conditions ap ly.
