ROLLER, SKATE..

applicati@ mea october ia, was. sensi No. creta My invention relates to roller skates and particularly to the class of skates known as rink skates which are used by professional skaters orhigh speed hd exhibit skating.

t One of the objects of my invention is to provide a cheap, simple and elicient orm of roller skate, which, by the elimination of unnecessary parts will include only those parts absolutely necessary for the proper function- I" ing of the skate and limit the number of parts which are liable to get out of order and which will therefore-be -a skate which will give the vskater the fullest amount ofpleasure with the elimination of many l5 dangers attendant upon the roller skates as now manufactured and sold.

Another object of m invention is to provide a roller skate w ich will permit the bodv of the skater to assume any angular position, while the four rollers on the skate will always maintainy a contact with the floor. of the rink. This positive action caused by the weight of the skater upon the oot platev of the skate and which will tend to place the footplate in an angular position will always adjust' itself when the foot is lifted romthe Hoor or the inclination of the body changes Cto an upright position by means of the recoil mechanism hereinafter described.

A still. further object of my invention is to combine theseveral diHerent parts of the skate, eliminatin casting,` and insuring strength and dura ilit by making the com- 35. bined structure lby drop forging., so that the number of cooperating parts will be materially decreased.; l

Still another object of my invention is to eliminate a resilient member such as rubber, t0 etc., which in time deteriorate and become unsuitable for the purpose for which they are intended, by replacing the same with a spring which is so mounted as to always cause the,

footplate to return to a osition arallel 15 with the floor regardless o the osition it has .been caused to assume by .t e skater.

It is a well kndwn fact thatwhen rubber resilient means has been used for returning the footplate of the skate to its original position after bein angularly depressed by the skater, the ru ber loses a great -part of its resiliency and the footplat'e will, after a short usage, refuse to return to the position parallel with the floor. This, of course, is

Y aused byu-weighty skater all the lite out of one side of the rubber resilient part, so that one cannot hope to maintain the relative positions between the toot plate and the rollers. lin my invention ll use a coil spring which 1s never bent to a point near the modulus et elasticity so that the recoil of the spring is so positive that regardless of the weight of the skater the footplate will always return to its original position with relation to the rollers of the skate.

Other obects and advantages of my inventionwi be readily appreciated as the same becomesbetter understood by reference to the following description when considered in connection. -wth the accompanying .drawing, in which,

Like symbols of reference herein indicate like parts in each of the gures-ot the drawing.

As illustrated in the drawing, my im` proved roller skate has the ordinary jfootlate @extending across the top of the same 'or forming a resting place for the toot ot the skater vand is provided at the rear end thereof with a pair of upwardly extending wings 7 tor limiting the position of the heel which have-the usual holes 8 through the same for permitting a strap 10 to be passed therethrough for bucklingmaround t e instep of the skater. At a point near the iront4 of the ootplate, the same is provided with a pair of clamping members 9 connected by means of screw 11, and these clam ing members extend through the doveta ed recesses 12 in the lugs 13, while an upright forked portion 14 is adapted to position the screw bef tween said 1u and prevent any lon tudnal movement o 4the screw therein. lachof the clamping members have inclined faces in the r in the 5 is a cross sectional view of my ima right and lef-t hand threaded y lil-5 hanging of the rollers lugs 13 and have a downwardly rojectin the footplate 6 and forms a pivotal connecmember 16 which is threaded and adapte tion therewith. At a position beyond where to cooperatel with the threads on the opthe leaf or r1b 29 extends outwardly from posite ends of the screw 11. The screw 11 is provided with a square portion or shank 17 at each end of the same for receiving a key (not shown) for adjusting the clamping members into any position, such as for attachment and removal from the shoe of the skater.

The footplate 6 is provided with a reinforcing rib 18 which extends substantially the full length of the saine and is provided at a point near the rear of the same with a small lug 19 having a recess 2l therein, as later explained. At a point slightly to the rear of thevforked portion 14 is a recess l22 which will be later explained. At a point near the heel end of the footplate is a downwardly extended rojection commonly called a hanger 23, w ile another hanger 24 extends downward from that portion of the footplate 6 'usually covered by the ball of the foot or immediately beyond the metatarsal bones of the foot.

It has been the custom in manufacturing skates of this kind to rivet the footplate 6 to the supporting rib 18 and the heads of the'rivet extending above the `footplate often cause unusual calli and sore places on the foot of the wearer, andu to prevent and eliminate such conditions, I form the footplate, the supporting rib, the hangers, the clamping dovetailed portions, and the fork shaped portion of one piece by drop forging, so that the entire upper part of the skate for the has no parts to come out of adjustment and this elimination of cooperating parts will prevent accidents and' the laying u The skate is rollers 25 and of the skate for repairs.

provided with two pairs of 26, and in this particular instance wherein I am 'describing a rink skate, I prefer to use composition rollers which are light, durable, and will not discolor the skating rink on account of the lack of carbon in the same, although for street use, metal or wooden rollers m be used and my invention is not designed to include any particular material for the formation of said rollers. The rollersare provided with an axle 27 extending through each pair of same and are provided with the usual ball bearings and casings and plates for taking the end thrust, all 'of which is well known 'in the art and which I do not claim as any part of my invention except in so far as it may.- relate to the combination of parts herein described and claimed.` That portion of the axle 27 between the inner edges of each of the pairs of wheels is provided with a supporting member 28 which'has, at a position near t e center of the saine, an upwardly extending rib or leaf 29 which has a pivo'tal end 31 which fits into the reess 21 0n age of parts.,

the body portion 28 is a leaf or ear 32 which is provided at the center of the same with a semi-circular depression or concave portion V33, while a screw or bolt 34 is adapted to pass through a central opening 35 in the saine and extend upward and into a threaded hole 36 in the rear hanger 23. This bolt 34 has the under face of its head 37 shaped to fit the concave or semi-circular portion 33 of the ear 32 and a spiral spring 38 fits immediately around the outside of the concave portion 33 and extends upwardly into a spring cup 41 surrounding said bolt, while a lock nut 42 immediately at the bottom of said spring cup 41 and hanger 23 is adapted to lock the said bolt in any desired osition. It will therefore be apparent t at the amount of,tension between the footplate 6 and the roller members 26 can be very nicely adjusted by means of the slotted head 43 in the bolt 34 by adjusting the tension on the spring 381 The spring 38 tapers towards its upper end, that is the portion'i lying within the spring cup 41 is smaller in diameter than that portlon surrounding the semi-circular portion 33. The spring 44 cooperates with the leaf 45 and spring portion 46 connected with the hanger 47 in exactly the same manner as the corresponding parts in the rear truck of the skate, while the rib or leaf 48 has a pivotal end 49 which enters into and engages with the recess 22 in order to form a ivotal connection therewith.

Ehe operation of my improved roller skate is very easily described, as the shoe ofA the skater is clamped into the skate by having the heel of the shoe rest against the upwardly extending wings 7 and firmly secured therein by means of the strap 10 being attached through the buckle 2() across the instep of the skater while the sole of the shoe is attached to said footplate 6 by means of turning the shank or square portion 17 of the screw 11 which causes the upwardly extending members 15 of the attaching

members

12 and 13 to engage by their serrated faces with the solel of the shoe and thus firmly secure the same between said attaching members.

rollers

25 and 26 are pivoted through the pivotal ends 21 and 41 with their corresponding recesses so that the footplate 6 may be turned over to anangle o f at least 33, while still keepin both rollers of each truck on the floor of t e rink. This is accomplished bymeans of the compression of the sprin s 38v and 44 whichare depressed to one si e of the skater inclines.

In order to reventdislocation and breakhave found it advisable to The trucks or pairs of lsaine as the body of the spirit and purview of l under side of its bil incassa construct the member 28, the upwardly extending leaf or rib 29, and theear shaped portion 32 of a single piece and this can readily be accomplished by drop forgin which is thel most substantial method an will positively prevent the breakage 'of any .of the arts of the combination, sothat this, in com ination with the foot plate and the elements composing that combination, kwill form a skate comprising practically three major parts, that is the footplate and the two carriage or roller portions.

While l have shown and described a preferred embodiment of the invention, it should be understood that the details ofconstruction are capable of wide modification and variation without departing .from the spirit of the invention or sacrifcin anyvof the advantages thereof. Hence, reserve all such variations and modifications and mechanical equivalents as fall vwithin the the appended claims. l claim: j
