The foot plate 5 is of any cross section designed for lightness and strength and has its forward end 24 raised to the general level of the cover plate 6 of the foundation housing 2 and its rear ward end is equipped with a heel plate 25, adjustably mounted thereon in a manner to be explained, for longitudinal adjustment, and this plate is of the same level as the forwardend 5 24 of the foot plate and foundation, all of which forms a support for the foot of the skier.

Attached to the rear or raised portion of the heel plate 25, by a rivet B or other suitable means, not shown, is a strap 26 (represented in part by the diagonally positioned and parallel dotted lines) to provide means for holding the foot of the skier back against the raised portion, which raised portion provides a stop 21 against which the heel 28 will rest. The heel plate 25 terminates forwardly in a channel C in which adjustable heel irons 29 are secured to the heel plate 25, in a manner to be explained, in Fig. 10, and may be of any usual construction or as shown in Fig. 2, and in part in the perspective views in Figs. 6 and '7, that shown in Figs. 6 and 2 corresponding in part. The heel irons consist of opposed horizontal channel sections 30 provided with a slot extended to the inner end thereof, represented as at 3!, and these sections are slidably mounted in the chan nel C and secured by a bar 32 mounted in and filling said sections 39 to be rigidly tightened against the sections by the screws 33 which pass through the bar and the slot 3! of the channel sections for frictional securenient by a nut D against the inner side of the channel C. A third and centrally disposed screw 34 assists to bind thesections 39 in the channel C of the heel plate 25 by passing through the slot A to adjustably '45 secure the whole to the longitudinal piece 35 of the foot plate, in the usual manner of such construction, thereby providing, with the screw 36 similarly mounted to the rear of and in line with the last mentioned screw 36, to maintain the, heel plate in positive longitudinal alignment with the foot plate and with the heel irons perpendicular to the longitudinal axis thereof. The heel irons are also provided with the usual vertical and oppositely positioned jaws 3'! with which to engage the sides of the heel.

In the forward raised portion 24 of the foot plate side irons with similarly positioned and constructed jaws 39 are provided, with the exception that these jaws have an inwardly directed horizontal portion 40 having a lip 40 designed to seat on top of the sole ill of the shoe and the 'slot or groove 38' in the iron, shown in Fig. 6, is designed to facilitate vertical adjustments secured by the screw 42 to accommodate soles of different thickness between the lip 40' and the horizontal portion 24.

It is now apparent that when the side irons are secured to the sole of the shoe and with the heel iron brought against the heel thereof that 7 0 when the strap is brought over the instep the foot plate will positively respond to the slightest transverse movement of the foot.

The forward portion 43 of the footplate is extended and is preferably drilled to receive a steel 75 'or hardened hinge pin 44 which is extended transversely to substantially the outer edge of the binder and is secured in that position by the set screws represented by the circles 45.

Obviously different methods may be used to provide the hinge pin. The methods shown however are my preferred form as absolute rigidity is thus obtained and which rigidity in a hori- Zontal plane is highly essential in the binder.

Centrally disposed on the pin 44 is a cam 46 Whose position with respect to the foot plate is maintained absolute by a set screw 45' wherewith to secure the cam rigidly in a selected position on the pin it, and consequently with respect to the foot plate 3.

From the above it is obvious that by raising the heel plate 25lof the foot plate to the position indicated in Fig. 8, the releasing bar ll will be automatically forced forward by the cam, as shown in Fig. 5, against the tension of the spring thus uncovering the hinge sockets and permitting the pin to be withdrawn.

It is now apparent that to assemble the two parts, i. e. the foot plate and the foundation housing, that with the foot plate secured to the shoe, and the projecting ends of the pin 54 placed in registerable position with respect to the sockets of the securing plate, that by withdrawing the releasing bar manually the pin will seat in the sockets to be secured therein when the releasing bar is released for the purpose.

It is also apparent that any rotative movement of the foot will impart the same movement to the ski and any twist of the ankle or any movement required, as to provide say for edging, will also be communicated promptly to the ski. The end of the interior projection of the releasing bar is preferably rounded as shown and rests at all times against the face of the cam being held in contact therewith by the resiliency of the spring; therefore, with the cam face properly designed movement of the foot plate in a vertical arc about the pin will move the releasing bar automatically as the heel is raised, and movement of this bar will withdraw the locking bar to uncover the said sockets and by setting the cam properly the foot plate will be automatically released from the foundation house when a predetermined angle of one part ,(the'foot plate) with another part (the housing) is attained, and simultaneous pressure forward of the toe against the curve of cover plate, or toe rest, and the resiliency of the sole of the shoe will force the separation of the two parts the moment the lock is released.

It is now obvious that by transversely positioning the sockets and pins which go to form the hinge joining the two parts of the binder, and constructing that hinge in the substantial manner shown, that I have provided what might be termed a flexible-rigid binding, the flexibility enabling the Telemark positions to be readily accomplished without fear of separation of the parts until such a movement of the foot, as might be caused by a fall, would be reached; then and then only would separation occur.

In hill climbing, or side stepping, or herring boning, or in the kick turn, or even in landings and the jump, the toe is never bent to an angle that would release the foot from the ski. At the same time the transverse rigidity is so positive that the ski is under more'positive control than when thefoot is secure to the ski by a binding formed chiefly of leather straps. This is true in traversing, in the side step, in stemming, and the stem break. The device, therefore, is highly efficient in operation, and in addition when separation occurs the foot plate remains secured to the shoe and will thus provide a non-slipping adjunct that will materially assist the act of walking over the snow, should such act be necessary.

Having thus described my invention, I claim 1. A separable ski binder, consisting of a foundation housing securable to a ski, and a foot plate attached to said housing and arranged therewith for automatic release therefrom when a predetermined angle of one with the other is attained.
