` SKATE;

Appiication ined July as, 192e. semi NoQsrais.

To all whom t may concern: v

Be it known that I, WILLIAM G. LAnsiiN, a citizen of the United States, and a resident of Steger, in the county of Cook and State of Illinois, have. invented certain new and useful Improvements' in a Skate;` and I do hereby declare that the following is a full, clear, and exact description of the samerreference being had to the accompanying drawings and to the numerals of reference marked thereon, which form a part of this specification.

It isI an object of thisinvention to prepare a skate which may be securely fastened onto a shoe even when the sole of the shoe is very thin. i

It is afurther object of this invention to providea fastening means for the toe of the skate which may be readily changed to fit shoes of different size and shape.`

It is vafurther object of this invention to provide means for adjusting the length of the skate in a step by step way an-d to arrange the above-mentioned fastening means so that it shall cor-operate with the adjusting means. y

It is a further object of this invention to providey a lever for tightening the skate upon the shoe which `shall act by drawing the two end portions of the skate toward one another.

It isa further object of this invention to provide `a brace for the forward wheels of the skate in the case vof a roller skate, or

the forwardportion of the runner in the f case of `an ice skate, and to fasten this brace to the upper par-t of the skate without interfering with the adjusting o-r fastening means. mentioned above.

Other and further important objects of i this invention will be apparent from the disclosures in the accompanying drawings j and the following specification. f

`The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. y

' On the drawings: j

`Figure 3 is a longitudinal section on the line 3-8 of Fig. 2.

Figure 4 is a section upon the line 4 4 of Figure 2. j j

Figure 5 is a bottom plan view of a portion ofthe skate.

Figure 6 is a section upon the line 6-G of Figure 5.

As shown on the drawings:` j

The top or platform of the skate is made up of a forward plate 10 and a rear plate 11. In the front part of the skate the forward plate 10 is on top, but in the rear part of the skate the rear plate 11 is on top. The change is made as indicated at 12 by the front plate 10 being offset enough to permit the rear plate 11 to pass through a slot 13 in the front portion.

The forward plate10 of theskate is attached to the supports 17 in any usual or convenient manner, as indicated at 14.y

Thesev supports 17 go tothe front wheels in the` case of a roller skate or to the front part of the runner in the case of an ice skate. Theforward portion of the ruimer or the front wheels are further supported by meansof a brace 15 which extends upward and rearwardly and terminates in a horizontal portion'16 which contacts with a` flat part of the front plate 10 just to the rear of the plug 13. i i i A bolt 18 goes through both

plates

10 and 11 to secure the brace 15 in place. A nut 19 is threaded onto the under end of the bolt 18 and a squared portion 2O is provided just under the `head of the bolt `to afford a shoulder contacting with the upper face of the plate 10. i The sides of the squared portion `2O bear against the edges of a slot 21 which extends from the forward end of the plate 11 to a point near where this plate widens out to make the support for the heel of the shoe. The `edges of this slot guide the plate 11 in its tele-` scopic movement over and through the plate 10. j

.Further guidance is afforded by a bolt 23 Vwhich is positioned near the rear end of the slot 21. The position of the bolt 23 is fixed by means of abearing piece or washer `24 `which has a pair of ears 25, the outer i ends of which turn down as shown at 26 in Figure 6. i The turneddown ends of the ears 25 engage in a pair of holes belonging totherows of holes 27 provided in the plate-11. These rows are parallel to and on each side of theslot 21 so that the position of the bolt 23 may be varied along the slot 21 by placing the ears 25 so that their down-turned ends enter the pair of holes 27 which is at the selected point. Then the ends 26 have been placed in theholes 27 N Y, 1,535,422 UNITED `STATES PATENT oFFicr-i.j

the bolt 23 is held stationary relative to the part ll.

The portion of the shank of the bolt 23 immediately under the washer 24 serves as a guide for the plate ll by contacting with the edges of the slot 21. The portion of the bolt 23 immediately below this serves as a guide for the motion of the plate l() by projecting through a slot 2S in the plate l0. The slot 28 does not extend as far forward as the bolt 1S, but the threaded part of this bolt passes through a round hole in the plate l0 immediately under the squared portion 20, as may be seen in Figure 3. Thus the bolt 18 moves only with the plate l() and the bolt 23 moves only with the plate ll. Pivotally mounted upon the bolt 23 immediately below the plate l() is a lever 30, and immediately below the lever the bolt is provided with a shoulder so that a nut 81 screwed upon the end of the bolt will not clamp the lever 30, part l() and part ll together and thus introduce friction. At the rear end of the slot 28 some of the material of the part is bent downward to form a lug 32. The rear end of the lever is formed into a cam 33 to cooperate with this lug. The lever at its rear end is also supplied with 'a shoulder 34 to contact with one edge of the lug 32 and act as a stop. The forward end of the lever is provide-d with a downwardly projecting finger piece 34a by which the lever 'is manipulated.

The forward end of the part 10 is provided with a cap or receptacle l() to rece-ive the toe of the shoe. This receptacle may be of whatever shape is necessary to iit the paryticular style of shoe worn by the user of the skate. ln order that this cap may be easily changed to accommodate different shoes,` it is detachably secured to the part l0. The preferred form of detachable fastening` is illustrated but many other forms are available. As illustrated, the fastening consists of tongues 41 and l2 integral with the cap and projecting down through slots in the plate l0. The ends of these tongues are bent against the under side of the plate l0 to prevent the removal of the cap 40. Then it is desired to remove the cap, it is easy to straighten the tongues. The receptacle may be made of any suitable material. If the material is hard, for example if it is sheet metal, it is preferably lined with some soft material such as felt, as is shown at 43. Preferably provision is made for ventilation, as for example by means of holes 44 arranged in any desired pattern in the sheet metal cap 40.

In the operation of the device the nut 3l. is iirst loosened until the bolt 23 can be lifted far enough for the ends 26 of the ears 25 to be removed from the holes 27. The bolt 23 Wit/ll th@ nfaslier 2l is then moved lengthwise of the plate 1l until the ears 25 are opposite the selected pair of holes 27. The nut 3l is then again tightened and brings the ends 26 of these ears into said holes.

The lever 5l() is then placed at right angles to the position illustrated in Figure 5, with the result that the cam 33 presents its narrowest part to the lug 32. The shoe is then placed vou the skate. This is most conveniently done when the user is wearing the shoe. He puts his foot into the skate just as he would ordinarily into a shoe. The toe of the shoe enters the housing 40 and the heel of the shoe presses against the heel plate 50 and forces the part ll backward until the edge of the cam ib is brought lirmly against the lug The pair of holes 27 is so selected that this will occur when the shoe has become lirmly seated against the tlat top of the skate. Preferably there should be a very slight lost motion between the cap 40, the plate 50 and the shoe. When the shoe is thus in position the leve-r 30 is turned into the positionillustrated in Figure 5, with the result that the cam 33 forces the lug` 32 backward. This moves the part l() backward and so lessens the distance between the cap and the heel plate 50, with the result that the shoe is firmly clamped between the two. Thus the clamping upon the toe of the shoe is effected by the whole bearing surface of the housing 40 and does not depend upon clamps pressing against the edge of the sole.

Vertical motion of the parts relative to the shoe is prevented by means of a strap 5l. It is, however, understood that other fastening means for the heel may be used instead of this strap.

then the skate is to be removed, the lever 3() is turned through a right angle, the strap 5l released, and the shoe lifted out. ln order to remove the skate it is not necessary to loosen the nut 31. It need be loosened only when the length of the skate .is to be altered to fit a different shoe. It is not necessary to loosen the nut 19 even for such adjustment of length.

l am aware that numerous details of construction may be varied through a widerange without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than is necessitated by the prior art.

I claim as my invention:

l. ln a skate, a toe plate, a heel plate telescopically mounted on the toe plate, said heel plate having a row of holes, a pivot, a mounting for said pivot, said mounting including a. part adapted to project into one of said holes, means for securing said mounting in place with said part projecting into the selected one of said holes, a lever on said pivot. and means integral with one oll said plates co-operating with said lever to limit the telescopic motion of said plates.

2. In a skate, a heel plate, a toe plate telescopically adjustable with respectto the heel plate., means for guiding and maintaining said plates in telescopic relation comprising an adjustable iulcrum membel` upon said heel plate extending through said toe pla-te, and a cam lever pivoted upon said member, said toe plate having an abutment 'for engagement by said lever.

3. In a skate, a heel plate, a toe plate telescopically adjustable With respect to the heel plate, a fulcrum bolt adjustable longi-` tudinally with respect to the heel plate, and a cam lever mounted upon said fnlcrnm plate adapted for engaging and shifting said toe plate and locking the same in adjusted position.

4. In a. skate, a toe plate, a heel plate, said plates beingl telescopically supported and relatively7 adjustable, a depending fulcrum element adjustable longitudinally with respect to one of said` plates, and a cam lever-pivoted upon said fulcrum element, and adapted for engaging and shifting,l the other plate and locking the same with respect to j 'the lst plate.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing Witnesses.
