My invention relates to roller skates, and among the objects thereof are to provide a construction which will permit a max1mum range of adjustment between short and long sizes or lengths to fit the shoes of dlflerent 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 shank girder, as-well as the rear flange of the heel plate are made in one piece, thereby permltting the same to be stamped in a single blank with a cutting die and formed into proper shape in a simplemanner to give extraordinary strength and resistance to sag or looseness at the shank; to provide a shank girder of inverted channel or U-shaped cross-section soas to present a much neater and finished appearance and give better bracing effect as well as prevent-exposure of the edgesof the shank; to provide novel truss supports and truck hangers for the front and rear or heel and toe or foot plates and wheels thereof, which from the same stamping and forming dies for either rigid or oscillating cushion trucks for the Wheels, thus economizing in manufacturing costs; to so construct the front hangers as to frictionally receive the shank girder for sliding adjustment between the same and v the toe plate, as well as to avoid lay thereberween, andito provide means or rigidly clamping said parts together, whereby they will positively remain fixed in any adjusted position.

Other objects and advantages of the invention will be understood by reference to the following specification when considered in connection with the accompanying drawing, in which Fig. 1 is a side elevation of one form of skate construction in accordance with the invention.

Fig. 12 is a plan view of a blank from which the truck hanger shown in Figures 10 and 11 is roduced. eferring to the drawings in detail and especially to the construct-ions shown in Fi ures 1 to 5 inclusive in which the skate is illustrated as being of that type havin rigid truck hangers, 13 designates the hee plate 'which isproduced from a single blank of metal stamped from a sheet so as to produce a combined heel plate, rear flange, and shank girder, the rear flange being designated at 14 and the shank girder at 15. The heel plate 13 has its side edges turned downwardly to produce stiffening flanges 16 and the rear flange 14 is bent upwardly with a slight rearward inclination and is curved to conform to the rear edgeof the plate 13 and the heel whichit is adapted to-fit. The roesult is a flange of concavo-convex formation;

with a convex top edge 17 and frontedge f 18 which are convexly 'roundedoand slopedownwardly and rearwardly to doubled lower side portions 19 below the plane of the heel-plate 13 and which approach the plane. of the plate in an upward curve rearwardly at each side. a

so as to reinforce and sti doubled portions 19, ,as before stated, depend below the plane of the heel plate 13 with resultant inside depressions or grooves 20 which form continuations of the depending side flangeslfi of the heel plate,.

with the shank girder 15, at which point the f shank 'rder is slii tly depressed to bring it in a p ane beneat the toe plate 22 of the skate. The flanges 16 are continued along the sides of the shank girder 15 as indicated at 23, besides the flanges being preferably vertically disposed in parallel relation to each other so as to form a member which is narrower thanthe heel plate and of substantially inverted channel or U-shaped crosssection. The shank girder. 15 has a longitudinal slot 24 centrally of its top portion extending the greater portion of the length thereof equi-distantly between. the sides and terminating in spaced relation to the depressed portion 21 at its juncture with its heel plate and the forward extremity. The rear flange is provided with inclined slots 25 adapted to take a strap or strap sections 26 for tightening the skate around the ankle of the skater. The toe plate 22 is equipped with the usual toe clamps27 slidably mounted beneath the toe plate for adjustment toward and away from each other by means of an adjusting screw 28, as commonly employed. Both the heel and toe plates are provided with. op-

posed pairs of spaced slots 29 preferably disposed equi-distantly apart and parallel toeach other, four in number being preferably employed on each plate and those of the toe plate being preferably located nearer the rear end thereof than its forward end to which the toe clamps 27 are fastened.

This type of skate is-equipped with 171g1d truck hangers 30, which are of like construction at both front and rear except for slightv modification of the front truck hanger for co-operation with the shank girder 15 for permitting adjustment .of the length of the skate, as will be hereinafter more particularly pointed out. These modifications consist in treatment of the blank as'additio'nal" operations to those required for the stamping and formation of the rear hanger. There fore, both hangers are of the same orjduplicate construction and may be produced} by thesame. stamping and forming dies.

As shownmore particularly in Figures 4.

and'5, these truck hangers are p'i oducedfrom a blank having an intermediate-"portion:31:' with side extensions 32 turnedtof proylde( strap sections or axle receiv ngportio'nsof;

substantial tubular formation shown in-Fi ure 4, the intermediate, portion;'of, the.

vthe bottom of the heel and toe plates 3O produced'by p the extensions a ce'ntral intermediateportion47' of the part being stifl'ened longitudinally with bentnb 33 which, however, termmates short of the inner ends of each hanger, as designated at 34. The blank is also provided with side ceiving or transverse bi ht portion 32 is .formed and the interme 'ate parts 37 and 38 are bent upwardly at obtuse angles to each other slightly greater than a right angle. By this means, the recessed edges 39 of the side extensions 35 and 36 are brought together vertically above the axle-receiving portion 32, and the edges 40 which engage are provided with reduced extensions or lug-rivets 41 which are received in the slots 29 and upset to securely fasten the truck hangers in position.

The front and rear truck hangers are of similar construction so far as described, but they are disposed in reversed positions with the lon est inclined portions produced by the fol ing lines 42 between the portions 35 and 37 disposed innermost as compared to the folding lines 43 between the portions 36 and 38 WhlCll are disposed toward the ends of the skate. Each truck hanger receives a pin or axle 44in its axle-receiving portion or strap section 32 in which the axle is clamped in pos1tionand wheels 45 are journaled on the axles.

The shank girder 15 extends between the sides of the front truck hanger, these sides being parallel and substantially U-shaped cross section as disclosed more particularly in Figures 2 and 4 of the drawings, the purpose of which is to permit adjustment of the length of the skate the truck; hanger beingof by sliding the toe plate and its hanger with brace the connection between the shank girder and the toe plate and front truck hanger, the latter is provided withshoulders 46 facing upwardly on the inside to engage the bottom ed es of the flanges 23. These shoulders are s iown in the form of indented portions or lugs produced in the side exten sions 35 to tight-ly friction against the bottom edgesof the flanges 23 but with suflicient ;looseness to'permit sliding adjustment of the shank. girderv in the front truck hanger.

i The -flanges' 23" also fit, against .the inner faces of'the sidewalls of the truck hangers 35 and 36 and 37v is slit as at '48 and turnedup to engage the bottom face of the shank gir er 15' to addi ,of the rear flange 14 and, of course,

. unease which are only provided on the front hanger.

and that these parts may be otherwise stam ed and shaped from the same stamping and orming dies. 7

In the form shown in Fi res 6 to 12 inclusive, the construction is i entical with the construction previously described except that the strap 51 is shown encircling the gacg ot straps 26 and 51 have the usual buckle, known in the art. In lieu of the truck hangers 30,

- sc -truck; hangers 52 are provided, the same be- *'stamped from a single blank to provide an intermediate axle mounting or transverse bight portion 53 with dependin ends 54 and having" side extensions 55 ranching from the side edges of the intermediate part 53 and enlarged outwardly. These portions 55 are disposed in divergent relation so that when they are bent up at right angles they are disposed parallel with the top edges 56 horizontal. These edges have correspondingly reduced portions or lug rivets 57 which are passed through the slots 29 and upset.

The sides 55 are also oflset outwardly along lines parallel to the edges 56 as shown at 58 to provide stiffening means as well as to form shoulders facing upwardly at the inside as at 59. These shoulders are designed to receive the bottom edges of the flanges 23 tions 65,

' as not to give at connected by the cushion tread type.

of the shank girder in frictional contact therewith as seen more particularly in Figures 6 and 8 so as to brace the parts when bolt 49, as previously described. The portions 54 are apertured as at- 60 and receive therebetween the usual oscillating cushion truck supports 61 which have rubber inserts 62 and the portions 54 are connected by pins 63 to corresponding apertured upturned portions of strap secthis construction being such as to permit cushioning of the wheels and tilting of the trucks transversely of the skate.

The axles 64 are mounted in the strap sections or axle receiving portions 65 and take the wheels 66, which ma be of metal or front and rear truck girders may be produced from the same dies, although if desired the front truck may have its sides more widely spaced apart, but this is not essential. In each case a skate of pleasing appearance is provided which is very strong and rigid and effectively embraced intermediately so the joint or shank portion where the shank girder and toe plate connect.

While I have shown several means of acpending side portions being unite In this construction the.

complishin the objects of the invention, it is to be un erstood that other forms may be provided and that modifications may be resorted to in the construction and arrangement of the parts withoutdeparting from the spirit of my invention so long'a's the same do not depart from the scope of the device as claimed.
