ICE SKATE CONSTRUCTION Filed Ma'r'ch 9, 1946 Patented Mar. 8, 1949 UNITED STATES ICE SKATE. CONSTRUCTION Application March 9, 1946, Serial No. 653,389

1 Claim. 1

This invention relates to improvements in ice skate construction.

The novel features of the invention are directed to the provision of ice skates characterized by rigidity and strength of construction, light wei ht, and relatively low manufacturing costs.

According to novel features of the invention the skate includes a blade to which are secured posts that support toe and heel supportin plates. The posts are constructed from secured together members providing a cross section which is considerably greater in dimension longitudinally of the skate than transversely thereof which not only provides the desired rigidity and strength but also offers relatively small resistance to ice particles, snow or the like when encountered by the skates.

As a special feature of the invention, the posts, being constructed from separate members, are readily and easily produced so as to result in economy of manufacture.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Fig. 1 is a side elevational view of a skate embodying the novel features of the invention;

Fig. 2 is a plan view of the heel plate of the skate shown in Fig. 1;

Figs. 3 and 4 are enlarged sectional elevational views on the lines 33 and 5-4 respectively of Fig. 1;

Fig. 5 is a perspective view of one of the post forming members; and

Fig. 6 is a sectional plan view on the line of Fig. 1.

Referring now to the drawings more in detail, the invention will be fully described.

A blade or runner 2 is provided which includes a vertically disposed part 4 having an ice engaging edge 6 at its lower side and a transverse flange or head part 8. The blade is in the form of a T to provide rigidity and strength.

A toe plate It is supported from the blade by a forward brace i2 and a toe post it. A heel plate [8 is integral with a post i8 which is secured to the blade 4. The toe and heel plate may be provided with openings I9 as shown in Fig. 2 adapted to receive screws or the like for securing the skate to a shoe.

The heel plate l6 and post it are made from preformed parts 2i] which are preferably formed from sheet metal by a suitable stamping or presslng operation. The parts 29 are secured together in back to back relation as by welding or the like.

As shown in Fig. 5 the post part 2B of which there are two has an upper heel plate forming portion 22 with a part 2% depending therefrom at the lower end of which is a rearwardly extending slot 26 and a depending flange 28.

The members it are secured together in back to back relation at opposite vertical edges 30 and upper horizontal edges 32 so as to provide a strong, rigid, unitary structure having at its lower end an upwardly extending slot for the blade i and a transverse slot for the flange or head 8 of the blade.

As stated, the post parts are secured together as by welding indicated by W.

The depending part of the members 2% are concaved as indicated by 24 so that when secured together they provide a vertical passageway and form a horizontal section having outer side faces that diverge from the forward vertical edge to a central point and then converge to a rear vertical edge. In this way, the post is of relatively less width than length and is streamlined or knife-like so as to be adapted to cut through and offer very little resistance to snow or the like which may be on the ice.

The blade and flange 8 thereof are received between the lower portions of the post member and the parts are constructed so that a snug fit is provided. The portions 28 may be secured to the lads by rivets if desired and preferably there will be a secure bond as by brazing, soldering or the like of contiguous surfaces of the blade and its flange with the lower portions of the members 23 thereby to rigidly and strongly secure the post to the blade.

The post id is formed from members 36 which are similar to those 20 already described and these are secured together in a manner similar thereto so as to provide a post having the characteristics of the post l8.

The lower portions 31 of the post M are secured to the blade after the manner of the post i8. At the upper side of the post Hi there are plate portions 38 to which one end of toe plate ill is secured.

The brace l2 has upper ear portions I3 which are secured to the forward portion of the toe plate in any suitable manner and lower portions i5 which are secured-to the flange 8 and the blade 4 similarly to the posts I4 and I8.

By forming the posts l4 and I8 from preformed parts they may be made from sheet metal thereby to result in economy of manufacture. At the same time, the posts are strong and rigid and are streamlined longitudinally of the skate so as to offer the minimum of resistance to snow and particles of ice which may be on the ice. Also the construction, while providing the desired strength and rigidity in a skate, is light in weight which is a desirable consideraton.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the United States is:

An ice skate comprising in combination, an elongated vertical blade having a horizontal T flange along the upper edge thereof extended outwardly from opposite longitudinal thereof, a heel post having a lower end secured to said blade adjacent the rear end thereof a toe post having a lower end secured to said blade sides forwardly of said heel post, each of said posts including a pair of similar upwardly extending sheet metal side plates having secured together forward and rear vertical edges curving inwardly relatively to one another with the side plates of the pairs thereof being relatively outwardly convexed between the vertical edges thereof forming posts which in horizontal cross section are substantially hollow ellipses having a transverse dimension which is less than that of the flange of said blade and a longitudinal dimension which is substantially greater than the transverse dimension, lower portions of the plates of the pairs thereof extending relatively outwardly on the flange of said blade and downwardly on the longitudinal edges of the flanges and then inwardly therebelow onto the sides of said blade, upper portions of the plates of the pairs thereof extending relatively outwardly providing supports, and a plate secured to the outwardly extending portions of the plates of said toe post.
