My invention relates to skates and ore especially to a novel construction of roller skate which may Without diiiiculty be interchangeably made into and used as an ice skate by the user, and among the other objects of the invention are to provide a construction which will permit a maximum range of adj ustment'bctween short and long lengths or sizes to fit the shoes of different skaters; to provide a skate of rigid and durable construction which may be economically produced in quantities; to provide a novel construction in which the heel plate and rear flange, as well as foot plate, are each made in l# one piece, and to reinforce the same in a novel manner to provide extraordinary rigidity and strength against the same sagging andlooseness at the shank; to provide a shank girder of inverted channel or U-shaped cross section so as to present a much neater and more finished appearance by obviating the exposure of the edges of the shank; to pro,- vide novel truss supports and truck hangers for the front and rear or heel and toe plates and wheels thereof, which may be produced from novel blanks for connection with the foot plates and adapted to receive oscillating cushion trucks for the wheels or sled runners of novel construction, thus economizing in manufacturing costs; to provide means for. rigidly clamping said parts'in position when adjusted by sliding one on the other whereby they will positively remain inl the desired adjusted position.

With the above and other objects in view,

the invention consists in certainenovel structurev and arrangement of parts to be hereinafter more particularly specied and pointed out in the claims.

Referring to the drawings in detail, and more especially to Figures 1 to 5 inclusive, 9 designates the heel plate of the skate which is stamped from sheet metal in a single blank and formed with an integral rear or heel iange 10 directed upwardly therefrom. At the juncture of the heel plate and flange, the blank is convexly rounded and slopes downwardly and rearwardly and then forwardly to a pointbeneath the heel plate at the sides where the metal is doubled on itself,y as indiL cated at l1, the forward portions of the curved heel flange l() preferably tapering and having their upper edges sloping downwardly in convex formation and curved rearwardly at the bottom or juncture. of the sides of Vthe rear flange with the side edges of the heel plate as shown.

The rear flange has inclined slots l2 at each side adapted to take a strap 13 which is equipped with a suitable adjustable buckle connection y14 for securing the skate around' the ankle of the skater. The forward portion of the heel plate is tapered, the sideedges beyond the doubled portions 1l being turned A or curved downwardly as indicated at 15 to prevent exposure of the sharp edges as well as to stiifen the heel plate. These downturned portions or curved flanges extend around into the front edge of the heel plate vas indicated at 16 to provide-shoulders 17 with a recess therebetween for accommodating and bracingthe shank girder 18 which `fitsI therebetween. This shank girder may be a solid flat bar of spring stiffness, or nearly,r

so, but is preferably of inverted channel or U-shapedcross section,` having side ianges 19 and a longitudinal slot 20 in the web portion thereof for receiving a clamping bolt 21 disposed through an opening' in the front portion of the heel plate'so as to clamp the heel plate an adjusted position on the shank 1 00 girder by the tightening of the nut 22 on the O lt 2l.

The toe or foot plate is designated at 23 and carries a clamping bolt 24 through an 5 aperture therein near its rear end which enthe plain. The remaining ortions of thesi es of 20 lthe toe late are provlded with downturned curved anges 28 similar to the flanges 15 and 16 and terminatin at the' points 29 to provide shoulders facing inwardly toward each' other in opposite directions for engagin the opposite sides or flanges 19 of the shank girder 18 in the same manner as the shoulders 17. f

This construction serves to align the heel and toe plates while the flangesstrengthen plates from shifting or pivoting on the shank girder. At the forward portion of the toe plate the latter .is equipped with the usual toe clamp 30 slidably mounted therebeneath 5 for adjustment toward and away from each 4, plate being shown other by means of an adjusting screw 31,'as

commonly employed. In addition, both the toe and heel plates are provided with opposed -pairs of spaced slots 32, the slots Ain the .toe

aced apart a greater distance than the slots 1n the heel plate and preferably disposed in parallel relation and four 55 swin plate to which the toe clam 1n number on each plate and located nearer '45 the inner ends of the heel and toe plates than their outerends,that is, the rear end of the heel plate and the forward end of the toe 30 are fastened. The front and rear truckv angers are designated at 33 and 34, each being stamped from ora single section of sheet metal to provide an intermediate transverse bight or mollrtnut portion 35 with depending-:ends 36 ape to provide parallel ears w 'ch form 1n a housing for a rubber bumper 37 having a Abracket 38 ivoted thereto as4 by means o a pin 39. e bracket 38 consists of a section of metal" rebent to provide the 'axle or spindle portion 40 and upturned ends 41 whichl are apertured to form 'ears for-receiving the pivot 39. These ends are also tapered as shown. A retainer plate 42 has slots 43 for receiving the ears 36 and fits upon .therubber bumper 37 and has down- 35 bumper from turned vside portions 44 which prevent the unduly oscillating. The sides om the slot 20, and is similar-` terchangeably of the hangers 33 and 3 4 are disposed in di vergent relation in the blank and then bent at right angles to the intermediate portions 35 in opposite directions and parallel to each other. The sides of the hangers are referred to as being parallel, but the same results could be obtained by reducing the width of the shoulder atthe top of the hanger and forming the brackets so that the sides at the top are wider apart than at the bottom. This would act. as a brace, preventing the side thrust that under severe conditions might causevthe bracket to buckle. When so bent upwardly, they are arranged with their top -edges horizontal and formed with projec:

tions 45 to engage the slots 32 and are riveted -or upset to secure the hangers to the heel and .footplates I -These hangers have their upper portions offset outwardly as indicated at 46 to provide upwardly facing shoulders 47 at the Iinner sides of the hangers which engage the bottom edges .of the flanges 19 of the extension bar or shank member 18 which serves as a connection between the heel and foot plates by reason of the clamping members or bolts heretofore described. In the preferred construction, the front hanger 33 is 'made con- 'vsiderable longer than the rear hanger 34. 0 the same, aswell asv to keep the heel and toe The axles or spindles 48 are received in the bearings or spindle-receiving portions 40 and take wheels 49 which may be of metal or cushion tread type. These .spindles are generally in the form of'bolts"- having a head 50 at one end and a nut 51 at the other end which'adapt them to be readily detached in case it is desired to replace the rollers to in- 52 are employed consisting of members of U- shaped cross section having openings 53 in the'top portions 54 thereof conforming to the hangers and openings in the side portions which receive the axles. The bottom portions or runners are flanged outwardly, as

at 55, whichilang'es are continued upwardly 3at the curved front portions', as shown in 'Figure 6 of the drawings.

In Figures 7 and 8, the extension bar or shank 18 is shown reinforced with a bar 56 which is similarly slotted to receive 4he clamping means 20 and 24. This bar 56 fits within the inverted channel-shaped member 18 between the side ilanges`19 thereof so as to give additional strength to the shank portion. Otherwise, this construction is the same as heretofore described.-

roduce a rollerI or an ice skate. In making an 1ce skate sled runners tom faces 'of the heel and toe or foot plates will provide a very neat construction of pleasing appearance which is very strong and rigid and which will not sag or become loose.
