This invention relates to new and useful improvements in skates and has particular relation to skates of the type mounted on vwheels or rollers.

The principal object of the invention is to provide a skate as set forth having novel features of construction permitting the person skating thereon to describe curves of substantially small radii.

Another object of the invention is to provide a skate as set forth having novel features of construction permitting pivoting of the forward rollers of the skate with respect to the latter.

Another object of the invention is to provide a skate of the character set forth being provided with a double bearing for the pivotable spindle or pin of the front roller assembly.

Another object of the invention is to provide a skate of the character set forth having novel means for centering the front axle transversely with respect to the longitudinal axis of said skate.

Another object of the invention is to provide a skate of the character set forth including toe and heel supporting plates adjustably connected one to the other by means of a novel structural member.

A more specic object of the invention is to provide a skate of the character set forth having novel means including bearings fixed in a false axle together with a split sleeve arrangement for mounting the front axle in its supporting structure.

Other features and details of the invention and the construction thereof are set forth hereinafter and disclosed in the accompanying drawings, in which:

Fig. 9 is a detached view in perspective of the spindle control elements and their relationship to each other and said spindle.

Referring now more particularly to the drawings, a skate made in accordance with this invention comprises front and rear top or shoe plates I and 2, respectively. In the present instance the front plate I is provided with the cus- 5 tomary shoe cleat elements 3 adjacent each side thereof, which may be adjusted by means of the threaded element 4 to meet the needs of the particular skater. 'I'he rear top plate 2 is provided with the customary back plates 5 having l0 slots 6 therein through which pass the customary ankle straps (not shown).

The aforementioned top plates I and 2 are mounted upon longitudinally extending channel members 1 and 8, respectively, and these l5 channel members are of such cross sectional shape and size as to permit the former to fit within the rear channel member 8 in the man-V ner of a telescopic joint. It will be noticed that these channel members 'I and 8, which are posi- 20 tioned with the opening facing downward, are provided at their lower or flange edges with inwardly extending flanges Ia and 8a. A washer 9 is disposed within the channel member I and rests upon the upper surfaces of the inwardly 25 extending flanges Ia thereof, the Washer in the present instance being provided with an aperture I0 therein through which extends a bolt II, said bolt II also extending through an aperture I2 formed in a plate I3 having a transverse cross- 30 section shape permitting said plate I3 to snugly embrace the external surface of the outer channel member 8 as shown in Fig. 3. 'I'he longitudinal extremities of the plate I3 are turned up as at I4 and these bent up portions are intend- 35 ed to engage suitably positioned slots I5 formed' in the bottom Webs 8a of the channel 8 as shown in Fig. 4. A nut I6 is tightened on the bolt Il as illustrated in the drawings, and precludes relative longitudinal movement of the overlapping 40 channel members 'I and 8. In the present instance the web of the inner channel 1 is split axially adjacent the forward end and the inwardly projecting flanges thus formed by the cut are turned and bent outwardly such as shown at 1h45 in Fig. 6 and these outwardly turned flange portions 'Ib of the channel member 1 are secured to the underside of the forward plate I by means of rivets I'I, which project upwardly through said flanges Ib and top plate I. The rivets I1 are 50 an integral part of plates I8, which extend rearwardly with respect to the skate from the spindle supporting bracket which is designated generally as I9.

More in detail the spindle supporting bracket 55 I9 includes upper and lower flanges 20 and 2|, connected by a web 22 from which the aforementioned plates I8 project. The forward portion of the lower` Web 2I of the bracket is upturned as yat 2Ia to form a tongue the purpose for which will be set forth in detail hereinafter. The anges and 2| of the bracket I9 are provided with aligned apertures 23 and 24 respectively, and a spindle 26 is rotatably mounted therein as shown in Fig. 5 of the drawings. In the present instance' the spindle 26 is provided with a shoulder 21, which is disposed in co-planar relation with the lower face of the bottom flange 2| of the spindle bracket I9 and this shoulder and the surrounding surface of said flange 2I rest upon the annular surface formed about the opening 28 in a plate 29. The front end 29a of the plate 29 is bent upwardly parallel with respect to the axis of the spindle 26 and the rear end 29b'of which is bent in the opposite direction also parallel to the axis of said spindle 26. The portion 29h is permanently connected to the projecting flanges 30 and 3l of a split sleeve member 32 as at 33. The sleeve 32 has a portion cut therefrom as at 34 and an aperture is formed in the top portion of said sleeve in alignment with the apertures 23 and 24 in the spindle bracket I9. The spindle 26 extends through the aperture in the plate 32 and the latter is secured to said spindle by means of an arcuately shaped plate 35 disposed Within the sleeve 32 and permanently retained on the spindle by distorting or attening the head thereof as at 36.

In the present instance the bottom flange 2I of the pivot spindle bracket I9 has two segments cut therefrom as indicated at 31--31 leaving a central portion 2 I a which is bent upwardly parallel to the axis of the spindle 26. The angularly disposed edges 31--31 of the cut out portions constitute stops which are engaged by the projecting tongue 29a of the plate 29 to limit rotation of the latter, the spindle 26 and the sleeve 32 secured thereto. A pair of annular elements 39 loosely embrace the spindle 26 and these members 39 are provided with forwardly projecting portions 40, which engage undercuts 4I in the projecting tongue 29ak of the plate 29. An upstanding lug 42 is formed along the outer edge of each of the parallel arms 4I) and these lugs are provided with notches 43 in the inner edge thereof, which slots are arranged for engagement by the extremities of a spring 44 which is coiled about the spindle 26 as shown in Figs. 5 and 7 of the drawings. The spring 44 functions to yieldingly maintain the spindle 26, plate 29 and sleeve 32 in the relative positions shown in the drawings and yet permit the pivoting of these elements with respect to the bracket I9 in a direction and degree depending upon the location and amount of pressureapplied to the top plate I by the skater, the extent or degree of pivot of the aforementioned elements being positively limited by the projecting edges 3'I of the flange 2I of the bracket I9. The upwardly projecting tongue of the plate 2I extends between 'the arms and functions as a centering means for the relative pivotable elements of the front wheel assembly when in normal position and when these latter elements pivot in 'either direction the tongue 2Ia maintains the opposite arm 49 in its normal position axially with-respect to the skate, while the other arm is actuated by means of the tongue 29a of the plate 29, which rotates with the spindle 26. Obviously this rotation occurs against the action of the spring 44 and by maintaining the other arm 40 in its normal position, the extent of compression of the spring 44 is increased and affords an increased spring action to return the pivoted elements of the assembly to their normal position axially of the skate. 5

41 is formed centrally in the concave portion of 15 each of the cup-like members 45 and these apertures are of such diameter as to loosely embrace a sleeve 48, which is in turn mounted upon but not secured to a shaft 49 constituting the front axle of the skate. The cup-like members 45 20 constitute in each instance one member of a race for ball bearings 59 which are retained therein by means of a diverging curved element 5I, the inner edge of which is intended to abut the edges of the sleeve 48. It is pointed out that with the 25 edges of the diverging members 5I and the sleeve 43 in contact as shown, the curvature of said members 5I bears such relation with respect to the curvature of the cup-like members 45 that the ball bearings 5D will not be bound between the 30 latter two members but will be free to move about the race formed thereby.

A split sleeve 52 embraces a portion of the axle 49 adjacent each end thereof and the inner end of each of said sleeves 52 engages the convex sur- 35 face of the curved bearing retaining elements 45. Each end portion of the axle 49 is threaded as at 53 and retaining nuts 54 are tightened thereon and engage the outer ends of the split sleeve members 52, forcing into successive contact the 40 sleeve member 43, the bearing retaining elements 45 and the split sleeves 52 just described. definitely center the axle 49 of the front roller assembly transversely with respect to the longitudinal axis of the skate and axially with respect to the sleeve 45 32.

A wheel designated generally as 55 is mounted upon each of the split sleeves 52 as shown and these wheels are each provided with a hub 56 in the form of a sleeve movably mounted upon said 50 sleeves 52 for rotation circumferentially thereof as well as movement axially between the limits afforded by the ball bearing retaining elements 45 and the nuts 54. In the present instance the body of the wheel 51 is composed of wood, hard 55 rubber or other composition and this body member is out down as at 58 to receive circular angle members 59--59 as shown in Fig. 6, said cutout 58 being of such dimensions that the outer surface of the circular angle members 59 form a con- 60 tinuous smooth surface with the remaining surface of the body member 51. The circular angle members 59 are detachably secured to each wheel by means of bolts 60 which extend completely through the wheel and threadably engage the radial leg of the inner angle member as at 6I By arrangement of the spindle bracket I9 at an angle with respect to the top shoe plate I, the moment the skater applied pressure to the right or left side thereof, the spindle 26 will pivot In 70 said bracket and dispose the axle 49 and wheels 55 at an angle with respect to the transverse position in which they are normally maintained, the wheels 55 remaining in the turned position only'so long as the pressure is applied to the plate 75 I', and-when this pressure ceases or is lessened the spring willV return the spindle 2Q and wheels 5U to normal Vtransverse position or positions corresponding to the degree of pressure yetexisting on the plate I. s

In' using the skate which is the subject' of this invention, the skater may describe fancy figures and other courses that have heretofore been im- Lpossible withthe customary type of skate. The
