SKATE.

SPECIFICATION forming part of Letters Patent No. 489,088, dated January 3, 1893.

Application filed May 26, 1892.

T0 all whom iv may concern:

Be it known that I, CARL PACK, a subject of the Emperor of Germany. residing at Barmen, in the Province of Rhenish Prussia, Germany, have invented a new and useful Mechanism for Fixing the Sole and 1Ieel Cramps of Skates, of which the following isa specification.

My invention relates to improvements in skates in which a preliminary adjnstment of the sole and heel cramps is effected by hand and the final firm fixing is then done without the use of any screws by means of a rack and pinion motion pressing the heel cramp carrier and the sole cramp guide or the cramps respectively both at the same time or either of them alone-one being already driven fastfirmly against the heel and the soles respectively. I attain this object by the meehanism illustrated in the accompanying drawings,in which:

Figure 1 is a longitudinal section of the skate; Fig. 2 is a plan of the same showing the pinion lever set out of gear; Fig. 3 is a similar view showing the pinion in gear With a single rack and the lever in its closed position; Fig. 4: is a similar view, showing the pinion in gear with a double rack; Figs. 5 and 6 are cross sections along line II and II-1I of Figs. 1 and 4 respectively.

The sole cramps B are carried in depressions made into the soleplate A and they are adjusted crosswise in the well known manner by being joined by rivets to slide C having oblique slots cut therein in which the rivets are guided. This slide however is shifted forward and backward for preliminary ad justment at first by hand and then for securing the skate firmly the final adjustmentand fixing is done mechanically by means of a rack and pinion motion. In a similar manner the adjusting and fixing of theheel cramp is efi?ected. The said pinion which is only partly provided with teeth, either on one quarter side only or on two opposite sides forming a single or double quadrant is connected to a lever by means of which it can be turned round and also shifted lengthwise for the purposes mentioned. The slide C is provided With a pin E going through a slot F in the sole plate and being connected to the Serial No. 434,524. (No model.)

lever G. The pin E is firmly fixed to the lever G but it can be turned in the slide C and to it is also fastened the pinion or quadraut H which therefore can also be shifted lengthwise with the lever G and slide C. The rack K which forms a sort of a strap surrounding the pinion lies in the same level with the pinion between the sole plate and the lever and is provided at the back end with a bolt passing through the sole plate where the heel oramp Dis riveted to it. Now according to the position given to the lever G or to the quadrant H the rack may be shifted lengthwise without influencing the lever G and this may be shitted lengthwise together with the pinion and the slide C without interfering With the rack K. As will be seen from Fg. 2 this is the case when the lever G stands at rightangle to the skate and now the preliminary adjustment of the sole cramps and of the heel cramp may be done.- When then the lever is turned backward the teeth of the quadrant H gear into the teeth of the rack and by bringing the lever into the position shown in Fig. 3 either the rack with the heel cramp is forced backward firmly against the heel, the slide C carrying the pinion standing fast or, the rack being fast against the heel, the pinion rolls along the rack forcing the slide C forward and pressing the sole cramps firmly against the soles, or, What Will be the likeliest result, both, the sole cramps and the heeloramp will be alternately driveu fast and the skate will be held firm and sure to the shoe or boot. It is self evident that the pinion may be provided 011 two opposite sides with teeth and that then the rack also may have teeth on both sides and instead of being made in form of a single toothed Strap it will be formed as two racks, the one M being joined to the heeloramp (D), the other (N) together with the lever(G) and pinion (H') being fastened to the slide (C) (Fig. 4) and the action is then the same: by turning the lever and pinion M and N are shifted lengthwise in opposite directions together or one of them alone securing firmly the respective cramps. The ditterence in both cases being merely matter of design.

Having now described the nature of my invention and in what manner the same is to IOO be performed, I declare that what I claim as to and fr0, in combination With a rack (K) my invention, and desire to secure by Letters carrying the hee1 cramp (D) the teeth of the ro Patent, is: rack engaging With the teeth of the quadrant In a skate a 1ever (G) a pinion or a. quad- (H) in turning the lever (G) backward.
