11 Claims.

My invention relates to roller skates and it has vfor its object the provision of a new and improved form and arrangement of parts by which a maximum of strength is provided by the use of a minis mum amount of metal and whereby the manufacture, plating and assembly of the parts may be eiected with the least trouble and expense.

Itis one of the objects of my invention to provide an improved resilient mounting for the axle l by which. the supporting wheels of the skate are connected with the framework,` and to provide an improved arrangement of connecting means between the frame and the outside sleeve forming a part of such resilient mounting. It is another object of my invention to provide an improved arrangement of extension bar and associated parts by which the toe plate and the heel plate of the framework are adjustably connected together, whereby an easy adjustment may be ef- 2 fected and whereby great strength shall be provided by the use of a comparatively small amount of metal. More speciiically, it is one of the objects of the invention to provide an improved arrangement of axle mounting means and its connection with the frame by means of brackets all arranged in combination with an extension bar which is adapted by cooperation with the brackets to serve effectively for extension purposes while so serving automatically to hold the front and rear portions of the framein the desired angular adjustment with respect toeach other. Y

It is another object of my invention to provide an improved arrangement of bracket means by which a downwardly open channel is formed, the sheet metal forming the top wall of the channel being curved l'downwardly so as to close one end of the channel and serving thus to give the channel a high degree of strength with respect to transverse pressure thereon. Another object is to provide a channel as above specified with the wall portions in angular relationship to each othersoastoenableanextensionbarofsimilar shape to provide substantial transverse reinforoe- 45 ment, strengthening ribs being provided in the upper portions of the brackets merging at theirlower ends into the walls of the channel.

' Referring now to the several gures of the drawings in which corresponding parts are indicated by the same reference characters, i5 indicates the heel plate forming a part of the' framey work of the skate. being provided with an upstanding flange Il as usual at its rear end portion and being provided with downwardly extending anges I1 along its side edges. as is clearly shown in Fig. 2. The heel plate Il is connected with supporting wheels Il of any approved type carried by an axle bolt Il bymeans of suitable connecting parts as hereinafter described cooperating with brackets 20 and-2 I, as is clearly shown in F18. 2.

The bracket 2l is shown. in Fig. 8, the other 40 bracket 2l being similar except that they are reversely formed for use at opposite sides. As shown in Fig. 8, the bracket 2l comprises a vertically disposed plate portion 22 having a transversely disposed ilange portion 2l` at itsupper 45 edge. The two brackets 24 and 2l are secured to the bottom face of the transverse frame or heel plate i8. being securely welded at several places to the plate Il and also to each other at points along the vertical plate or web portions 22v which 50 stand in face to face engagement with each other.

At a distance below the ilanges 23, each of the brackets lis oifset outwardly so as to provide a downwardly open channel portion 24 the top wall portions 2! at opposite sides of the channel pross viding outwardly facing shoulders, strengthening ribs 25 being pressed in the vertical plate or web portions 22 from the upper edges of such vertical I plate portions and extending downwardly atan angle so as to merge into the top wall portions as is clearly shown in Fig. 8. At their forward ends, the brackets are provided with overlapping lugs 21 and 28, see Fig. 9. which are effectively connected together as hereinafter described for reinforcing the structure. At their lower edges, each of the brackets 2l and 2|` is provided with a downwardly extending arm 23 which is provided with a collar formed integrally therewith, the two collars 30 of the two brackets being opposltely disposed in axially aligned position with respect to each other. Each of. the brackets is provided at its lower edge with an inwardly extending ange 3l which is continued downwardly along the front face of the arm 28 to a point adjacent the collar 38.

At the forward end o'f the skate, a toe plate 32 is provided having downwardly extending anges 33 along its side portions and a downwardly extending flange 34 across the front end. The transverse frame or toe plate 32 is supported by wheels 35 of any suitable type mounted upon an axle bolt 35 connected with the toe plate 32 by means as hereinafter described comprising brackets 31 and 38 as is best shown in Fig. 3.

7 5 together by means of a metal sleeve 41 which isy The brackets 31 and 38 are arranged in general similarity to the brackets 2li and 2|, the two brackets 31 and 38 being similar to each other except for reversed arrangement for enabling them to be used at opposite sides in cooperation with each other. As is best shown in Fig. 7, each of the brackets 31 and 3l comprises a vertically disposed plate portion 3l provided at its upper edge with a transversely disposed flange 4I, the two brackets 31 and 38 being secured to the toe plate by means of the anges 48 which are: securely welded at various points to the bottom face of said plate 32, the vertical plate portions 3l of the two brackets being firmly secured together at a plurality of points preferably by welding. Below the vertical plate portions 38, the two brackets are offset outwardly so as to provide a downwardly open channel. the top wall portion 4I of the channel at each side being disposed substantially parallel with the flange 4l and beingI braced strongly with respect thereto-by means of ribs 42 pressed in the vertical plate portions 38 extending downwardly therein from the upper edge of the vertical plate portions and merging at their lower ends into the top plate portions 4 I As is best shown in Fig. 7, the top plate portion 4| of each of the brackets is curved downwardly at the forward end of the bracket so as to close the front-end of the channel transversely serving thus to strengthen the channel formation greatly with respect to transverse pressure thereon, the curved shoulder portion by which the closure of the channel is effected being formed in a downwardly extending arm 43. At its lower end, the arm 43 of each of the brackets is provided with an outwardly extending collar 44 formed integrally with the arm, the collars 44 of the two brackets being oppositely disposed in axial augment with each other.- At their rear ends. the bracket members 31 and 38 are provided with overlapping lugs 45 and 45 which are rigidly connected together by means of a bolt as hereinafter described, lthe bracket members being thus strongly reinforced with respect to each other.

The brackets 20 and 2l are further connected inserted within the aligned collars 3l being secured ilrmly in position therein by means of spotwelding or in any other suitable manner. The sleeve 41 is preferably rolled out of at stock and is provided at .one end with an inwardly turned flange 48, as is clearly shown in Fig. 6, the opposite end of the sleeve 41 initially being left open in cylindrical form as shown in Fig. 6. In the formation of the skate, the transverse frame or heel plate I5, the brackets 2li and 2| and the sleeve 41 are ilrst rmly secured together by spot-I welding with the sleeve 41 in the condition shown in Fig. 6. .The transverse frame or toe plate 32, thebrackets 31 and 38, and a sleeve 41 such as that shown in Fig. 6 are likewise rmly secured together preferably by spot-welding with such sleeve 41 in position within the collars 44. The parts are then in condition for plating which is preferably effected at this stage of the assembly.

After"th'e two units comprising the end portions of the framework are plated, each of the sleeves 41 is provided with an assembly such as that shown in Fig. 5 comprising a rubber sleeve 48 having an axle member 50 mounted therein also in the form of a Vsleeve having its middle portion expanded into the form of a ball as indicated at 5|.'the conformation of the rubber of the sleeve 48 being such that the rubber when held against radial expansion serves enectively for preventing the withdrawal of the axle member 5t. The end portions of the sleeve 48 however are flared so as to enable the axle member 5l to have free swinging movement with respect to the sleeve 41 about the ball 5i as a fulcrum. 'I'he axle member 58 is preferably formed out of dat stock and is of a size to receive snugly the axle bolts Il for mounting the wheels I8 in position thereon. After the .sleeves 58 and 48 have vbeen inserted into position within the sleeves 41,

the end portions of the sleeves 41 are turned inwardly in the form of a flange 52 corr the sleeve 41.

For connecting the end portions of the framework of the skate, I have provided an extension bar 53 in the form of a downwardly open channel, the channel bar 53 being of a size and shape to t snugly within the downwardly open channels of the brackets so as to hold the end portions of the framework in the desired alignment independently of the extension bar being fastened so as to prevent sliding movement thereof with respect to the channels of the framework. As is clearly shown in Fig. 9, the lower edges of' the side portions of the channel bar 53 abut against the flanges 3i of thechannel 24. In like manner the side portions of the bar 53 abut against inwardly extending anges 31a formed on the lower edges of the brackets 31 and 38. The relation is such, by reason of the snug ilt of the extension bar 53 within the channels of the framework, that the extension bar reinforces the framework strongly with respect to lateral pressure on the channel portions of the framework..

vthe usualadjusting screw member 8i which has a bearing in notches l! formed in the lower edge portions of the vertically disposed plates I! of the brackets, as is clearly shown in Figs. l and 7. In the arrangement shown, the brackets are extended' forwardly beyond the notches 02, being' provided at their ends with outwardly extending ilange portions 63 which are welded or otherwise ilrmly secured to the bottom face of the toe plate 32 for strengthening the frame construction.

By the use of my improved arrangement, I am enabled to form the parts of my improved skate very readily upon automatic machinery and am enabled very readily and rapidly to assemble the parts into the nnal form. The arrangement is such that the various parts rein-f force each other so as to produce a maximum of strength by the use of a minimum amount of material whereby I am enabled to keep the weight of the nnished skate down to a reasonable limit.

While I p refer to employ the form and arrangement of parts as shown in my drawings and as above described, it is to be understood that my invention is not limited thereto except so far as the narrower claims may be so limited in terms, it being understood that changes might well be madel in the form and arrangement of the parts without departing from my invention.
