17 Claims.

' My invention relates particularly to an improved'type of roller skates.

f The object of my invention is to provide roller skates with which roller skating may be carried out more effectively and with a greater smoothness due to the further elimination of the efiect of unevenness of the skating floor upon the skater. My invention is an improvement upon the subject matter of my copending applications Ser. No. 572,867, upon Skates, filed January 15, 1945, now Patent No. 2,542,829, granted February 20, 1951, Ser. No. 634,238, upon Roller Skates, filed December 11, 1945, now Patent No. 2,533,740, granted December 12, 1950, and Ser. No. 690,050, upon Skates for Roller Skating, filed August 12, 1946. A further object is to provide an elastic suspension for the skater from the chassis while at the same time, however, introducing sufficient rigidity into the suspending means so as to maintain effectively the assumed relative positions of ,the parts of the skates while at the same time preserving the necessary elasticity of the suspensions. A further object is to provide skates of this character in which metal contacts are eliminated between the chassis and the parts of the fskate'attached to the foot of the wearer. Fur- Ith'er objects of my invention will appear from the detailed description of the same hereinafter. While myinvention is capable of being carried out in many different ways, for the purpose of illustration I have shown only certain embodiinents' thereof in the accompanying drawings, in which f Fig. 1 is a side elevation of a skate partly in section, made in accordance with my invention, showing the same attached to a skating shoe and showing, also, thereon two alternative forms of elastic suspension on the front and rear of the skate, respectively, it being understood, of course, that both of these forms as shown can be on the same skate or either one of these forms of suspension may be adopted on both the frontand itherear of the skate if desired;

Fig. 13 is a rear fragmental elevation of the .same rear portion thereof; and

Fig. 14 is a vertical cross-section looking towards the end of the rear skate chassis shown in Fig. 13.

In the drawings, referring first to the suspensions shown in Figs. 1, 2 and 3, I have shown a skate shoe I of any desired character, but which may be similar to the shoe shown in my copending application Ser. No. 690,050 referred to above, or which may be a shoe made to conform to the contours of the foot of the wearer, preferably as shown in my U. S. PatentNo. 2,332,000, granted October 19, 1943, upon Method of Manufacturing Shoes. This shoe, if desired, may have a front lacing 2 and a side lacing 3, and may have at "the base of the shoe a pad 4 of any desired character, forming the sole of the shoe, which may be attached to a skate plate 5 of wood or of .any other material in any desired manner, by screws or otherwise, not shown. Attachedto the shoe plate 5 there is provided a front chassis 6 comprised of an aluminum alloy chassis plate 1 secured by screws 8 and 9 to the plate 5. The plate I may have depending therefrom, a front standard I0 provided witha centrally located longitudinal cylindrical screw-threaded rod [2 held within the standard I9 by nuts [3 and I4'. .In front of the nut l4 there are five compressed rubber discs l5 through which the rod l2 passes, and which are held in place by an end nut l6 screw-threaded on the end of the rod l2. The discs l5 provide a relatively rigid means to supplement, elastically, an elastic rubber suspension {oi -the chassis referred tomore in .detail herein diameter, or of any other desired size, and

which pass, alternately, upwardly over-the axle housing 11 adjacent the roller [9, then. down.- wardly beneath the discs l5 and upwardly over the axle housing I! adjacent the otherroller-2ll 4 by screws 55 and 56 tothe wooden plate 5, passing through adjusting slots 51 and 58 in the chassis plate 54. In this instance there is provided, furthermore, a hook 59 screw-threaded into the wooden plate 5 over which there are two forwardly directed sets of rubber cord windings 60 and GI and a set of windings 62 passing from the hook 59 downwardly. over. the. axle housing H, alternately, {on eitherside of the neck 29. It will be understood, of course, that in this inv stance the ring 22 may be of any desired size, so

as to give suflieient lateral breadth to provide lateral-stability for the suspension and support until a number of such windings are provided on either side of a ring 22 formed on the upper side of. the axle, housing H. The said ring, is inclined towards the front of'the skate; and its. upper endis'then connected by a pluralityof windings of a rubber. cord 2|, respectivelypassing'through the ring 22" and over the front' of a. screw-threaded hook 23 which is, screwthre'a'ded into the wooden plate 5, as well as, similarly', over' two lateral hooks 24 and 25, also screw-threaded into the plate. 5; so as to provide a plurality of such windings 26, 21 "and 28. The saidjring 2T, furthermore, has a neck 29 around which a;series of similar windings 30 of rubber cord pass upwardly over a rearwardly directed hook 3i ,screw-threaded into the wooden plate 5'. 'Allof these windings, furthermore, are applied withsome degree of'tension and'in such amanner. asjto providethe correctdesired alignment' ofthe rollers 19 and with regard to the skate plate 5.

- At the rear of Fig. 1 I have shown the rear end of the rod" I2 passing through a rear chassis standard 3.2 constructed and supported like the standard l0. Also, said rod IZ'has nuts. 33 and 34 holding between them fivecompressed'rubber discs,35; as on the front ofthe rod: II, which rest against the underside of a rear axle housing 36 with the aid ofrubber cord suspension windings 31, as' in the'case ofthe front. axle l8. "In this instance, however, the housing 3.6; which is lo cated on a rear axle:38, has a rearwardly directed hook'39. This hook 39.: has three sets of "windings 40,41: and42", as shown in Fig. 3, connecting it, respectively, to a rear'hookf4'4 an'd side hooks" 45.. and; '46; as. in the. .casewof the. ring 22 of the axlehousing I! from the skate plate 5 by 15 means of the ring and the screw 59. Iii Fig. 6 I have shown a slightly modified form! of the suspension illustrated in Fig. 4. In this'instan'ce, however, the axle !8 has an axle housing 53 provided with an upwardly and for-v wardly inclined "rod-64 havingweld'ecr thereto rings 65 and 66 whichcooperate;respetiyely} witha forward ring 61 and a rearwardlydocated ring 68 bothof which are 'welded one chassis plateG'Q connected by'screws '10 and -'H aspre'vi ouslyjdescribed; tothe wooden skateplate 5. n: this" instance, furthermore; there area-plrn-ality of'iru'bber' cord windings- 12 and 13*between the ring "65 and the" ring 51- and' between the ring 66' and the ring 68; respectively; the-suspension in thisinstancebeingotherwise'the same as' in Fig;4

Accordingly, this comprisesthe standard [mas-shownin-Figl, having the nuts l3 and I4 as well-as-the'nut I6 holding in" place the five'rubber discs'l5f and therubber cord'windings '21 for supporting; as

shown in the front portion of Fig. 1, the axle housing I! provided with the ring 2'2. Inthis instance; however, the ring 22, whichmaybe made as large as desired, "is connected bya; series threaded'into an angle bracket 53', said bracket '53 being formed on' a chassis" plate 5 connected inderT5 rests. Onthetopof the rubbencylind'er 15 there is a; retainerring-83 'to' compresstlie rubber cylinder 15 with, the aid of a nutfli'on the screw 16'', the-upper end'of the screw 16' being screw threaded into an inclined socket 85jonf a Fig. 8'-is somewhat similar 'to thatshown in 31i chassisplate 86' connectedby screws 81 88 to the" skate'plate 5." "The inclined socket" '85 carries around the outside thereof. a plrira-lityof windings of rubber cord "89Whi0h .passt'throug h a hooki fl' resting in'a'recess 91 carrying'asheet of rubber- 92" to, prevent?metal-to metai'. contact.

"It Willi be understoodthat thescrew hook" se n the front chassis plate tit-may-haveagscrewsl'eeve coupling 93, with reverse screw-threads 9'4fl'andi 95 therein, so" as to adjustablycouple the hook 9 0 with a similar screw hookt ficonnectedto arear skate chassis "(not shown), constructed 'in ithe same mannenas the front skate; chassis shown in t fl ef a Themodifiedflfornrof"chassis'bracket shownm :4, but can be used to advantage, for-instance, on

the foremost portion of the axle housing shown in Fig. 7. That is to say, in this instance, instead of the neck '29 and 'ring'22 being connected-to the axle housing I1, there is an upwardly and forwardly inclined rod 91 having its upper end 98 extending-through a hole 99 over a rubber sheet or disc I00, which projects throughthe hole 99, located in an inclined plate IOI brazed to the face of a chassis plate I02 and connected by screws I03 and I04 to the skate plate 5 so that the upper end 98 of the rod9I rests against, and supported from the face of the chassis plate I02 by the rubber sheet or disc I00.

--1n the modification of my invention shown in Figs, 9 and 10, I have provided the same type of rollers I9 and 20 on an axle I05 having thereon an axle housing I06, the two ends of which are connected together by an arched support I! provided with an upwardly directed hook I08.

The arched support I0! is provided in order to bridge over the rod I2 in the standard I0, as previously described, said rod I2 carrying thereon the-compressed rubber discs I as well as the nuts I4 and I6. In this instance, however, it will'be noted that the rubber discs I5 rest on the axle housing I06 beneath the arched support I01, a plurality of windings I09 of rubber cordbeing provided, extending beneath the housing I06 alternately to the front and rear thereof over the rubber discs I5. The hook I03 is supported from the plate 5 by means of the .four hooks 45, 46, 44 and 41 with rubber cord windings the same as shown at the rear of Fig. 1. "The modification of my invention shown in Figs. 11 to' 14 is a modified form of the skate chassis shown at the rear of the skate inFig. 1, having the same rod I2 and standards I0 and 32 carrying the same, said rod I2 having the same nuts I6, I4, I3, 33 and 34 as well as the compressed- Neoprene or natural rubber rings I5 and 35, all of which are mounted on the wooden plate 5, preferably made of plywood. On the plate 5 there is fastened in any desired manner a leather sole IIO forming a part of a'skate shoe III made in any desired manner. rings I5 and 35 are located, respectively, below the axle housings I1 and 36 for the axles I8 and 38-, said axle housings having, respectively, thereon upwardly-directed inclined hooks H2 and H3, providing for the steering or turning movement in skating. Projecting from the latter portion of the wooden plate 5, at the front thereof, there'is a large screw-eye II4 inclined forwardly near the front of the plate 5, in which it is carried, by a screw-threaded shank II5 ex-' tending through the plate 5. This screw-eye H4 acts as a stop, when brought into contact with the floor, by tipping the skate forwardly. It can also act as a brake, and for this purpose increased friction can be obtained by means of windings II! of a rawhide strip wound through the middle of the eye H4 and around the periphery thereof. The front hook H2 is elastically suspended from a pair of front hooks H8 and I I9 having their shanks screw-threaded into the wooden plate 5 of the leather sole IIO. Simi larly, the rear hook H3 is elastically fastened in the same manner to a pair of rear hooks I and I2I, also having their shanks screw-threaded through the wooden plate 5. Inasmuch as the elastic suspension of the hook II3 from the hooks I20 and I2I is substantially the same as the suspensionof the hook II2 from the hook IIBand II9, only the elastic suspension of the hook 'II3 willbehere described in detail. For

The rubber 6. this purpose, at the rear of the skate, a first set of about 20windings I22, forming a suspension, of rubber cord of the kindhereinabove referred to is provided, passing downwardly over one side of the axle .housing 36 beneath the rubber discs 35 and over the other side of the housing 36, as shown for instancein Fig. 13, these windings being-made so as to repeatedly cross one another, as shown in Fig. 11, owing to the fact that the windings pass downwardly from the front of oneside of the. housing 36 upwardly over the rear portion of the other side of the housing 36. It will be understood, of course. that all the windings of rubber cord applied in these Figs. 11 to 14 are all the same, except as herein specifically'otherwise -provided,are applied under a dis tinct tension, and are of Neoprene .or some other artificial rubber, though they may be of natural rubber. Then there is applied a second set I23. of windings of said cord which extend around the hook I20 through the hook II3, then around-the hook I2I, through the hook II3, again. around the hook 23 until there are about 10 of these windings. Thereafter, there is applied a third set of about 10 windings I24, going aroundthe hook I20 and through the hook II3. Thereafter, there is applied a fourth set of about 10 windings I25, going around the hook I2I and through the hook H3. The second, third and fourth sets of windingsform, in fact, an inclined pivot for the chassis. Next, there is applied a fifth set of about 10 windings I26 of said rubber cord, which may be denominated opposition windings to the suspension windings above referred to, going around the hook I20 beneath the axle housing 36. Then I apply a sixth set of about 10 windings I2I of said cord, which maybe called, also, opposition windings, going around the hook I2I and around the axle housing 36. As will'be seen in Fig. 14, these two sets of opposition windings I29 and I2! cross over each other at the rear of the axle housing 36. Thereupon, I apply from 10 to 30 choke windings I28, forming a seventh set thereof, which are wrapped approximately horizontally around the opposition windings I26 and I2! and around the outside of the hook II3 between the latter and the two hooks I20 and I2I. These choke windings take out any remaining free play or uncontrolled defiective movement between the axle housing-36 and the axle 38 therein as well as the rollers mounted on the said. axle 38. The

- axlefihousing 36 on the skate plate 35 while permittinglelastic deflection of said housing 36 on an axis I29 which, of course, is inclined up-' wardly in the direction of the angularity 'of the hook II3. At the front of Fig. 11 there is shown a variation of the modification just described, in that instead of the central rubber rings 35 I substitute a series of about 20 windings I29a of natural rubber cord which, of course, because of its great resiliency, does not become permanently deformed, and instead of the 20 windings I22 I may provide 10 inner suspension windings I29b-ofnatural rubber and 10 outer suspension windings I 290 of a rubber substitute, .as for instance Neoprene, which are each applied as in the case of the windings I22.

In the operation of my invention, referring first to Figs. 1 and 2, on account of theelastic suspension from the tightly wound rubber cord windings 2I, 26, 27, 28 and 30 the skater will besuspended between the respective windings due -.-to: his .weighmwhfletskatingn eliminate ing-anyitransmissiomofthe IIIiIllliiSiUllEl/TBIIJIIIOYE as to givesacconding-ly asehsationof smoothness:
