units s'uch,'for example, as that shown anddescribed in my U. S. Letters Patent Numb er 1,120,714, granted December 15, 1911.
Units of this class areusefu'l'in many different situations where it is desired "to provide a yielding orelastic connection between two parts or members which is both extensible and contractible lengthwise, but such units are primarily intended and particularly adapted for incorporation in a resilient wheel structure where a plurality thereof is employed to connect the hub section'of the wheel with the rim section of the latter so as to yieldingly hold the "hub section at the center of the rim section.
The unit of the patent referred to comprises aplurality of slidebars disposedside by side and longitudinally vslida'ble relatively, a coiled spring surrounding and beingconnected through a pair of abutments with said bars which serves to normally hold them in intermediate positions from which they are movable endwise in'either direction against the resistance of the spring when force is applied to the unit in a "direction to extend or contract the latter. In the operation of the unit of this patent there was a tendency for the slide bars 'to cant or swing sidewise relatively, particularly when the unit was condensed or contracted. This canting or relative swinging movement or tendency resulted in the slide barsfb-in'ding against the abutment menlbersfthereby cans: 'ing injurious wear and improperaction of parts. A
The main object of my present invention is to improve the construction of units of the character indicated, and particularly to obviate the undesirable feature just pointed out. i g
In the accompanying drawings;

Fig. 8 is a side elevation, partly in section, showing the unit fully contracted.
Fig. 9 is a section on line 9-9 of Fig. 8.
Fig. 10 shows one of the split washers hereinafter described. 7
Fig. 11 is a section on line 1l 11 of Fig. 1. My improved unit, as herein shown, fcomprises a middle or intermediate slide bar and a pair of outer slide bars 2, '2 arranged one at each side oftheintermediatefbar 1.-
The intermediate. slide bar 1' is made. with a shank portion 3 substant ally rectangular in OIOSSSGCtlOIl, at the lnner end of whlchis a 7 is a section "on line 7+7 of Fig. 8.
pair of 'oppositely'disposed lugs 4"which 7 provide a pair of shoulders :5 at theinner end of the shank. At the outer end of the shank portion 3 said intermediate slide'bar is made with a pair of oppositely disposed shoulders 6. The inner portion of each outer slide bar'is made with a shank portion/7 which isalso substantially rectangular in cross-section,. said shank portion being made 'at its inner end with a segmental flange 8 which provides a segmental shoulder 9, and at its outer end with a segmental shoulder 10. g
The lengths of the shanks 3iand 7 are the same so that when the three slide bars are asseniblec'l side by side as shown inFigs. 1
and 2, the segmental shoulders 10 of the outer bars 2 are in the same transverse plane with "the shoulderso of the intermediatebar while the segmental shoulders '9 of the'outer bars are in the same transv erse plane with the shoulders 6 of said intermediate bar.
Surrounding the shanks?) and 7 of the assembled bars, and slidable longitudinally thereon, are two tubular abutment members 11, 11, each made at its inner end with an inwardly projecting 'flange or. wall 12 formed with a pair of oppositelydi'sposed rectangular notches l3,' Fig."13, receivlng thesh'anks 7 of the two outer bars 2, and
with a pair of oppositely disposednotches 131 for usein assembling theparts' Each abutment member 11 contains a split washer .14, Fig. .10, ,seatedagainstone side of the wall or flange 12. Each split washer is made up of two separate half sections 15 formed with rectangular notches l6 snugly fitting the shanks 8 and 7 but freely slidable thereon. At the outer end of each'tu'bula-r abutment 11 in an outwardly projecting flange 17, and between the flanges 17 of 'the two abutments 11 is arranged a coiled spring 18' .whose oppositeends are occupied by said a'butments so that the spring is held out of with the other member or part. In the case of a resilient wheel one of these members or parts would vbe the'rim section of the 'vwheel and the other would bethe hub section thereof. 7 I t When the slide bars 1 and 2 are forced togetherflinto, or toward, the v condition shown in Fig. 8, the spring 18 tends to twist or cant the abutment members 11 and, acting through the latter, to swing or can't the bars' l'and 2 relatively'in a" direction paralv lel w th the planes of the joints between said ,bars. I To prevent such relative swinging displacement of the slide bars which has heretofore, caused binding and undue wear of the parts, I make the intermediatebar 1 with two longitudinal grooves .20, one at each side thereof, intohwhich fit tongues 21 provided upon the inner sides of the outer slide bars 2. In this waythe severalbars are all "splined or keyed together so as to mutually ,hold each other against being swungor canted sidewise in the manner re ferred to, anda't the same timesaid bars are 40v free to slide longitudinally in either direction under the influence of the load borneby the unit.
I As heretofore, the shoulders 5 and"? act through the splitwashers 14:,ai1d tubular abutments 11 to compress the spring 18 when the bars" 1 and 2 are-pulled outwardly while the shoulders 6 and '10 7 act through said washers and abut'ments to also compress said inwardly. V
WhatIclaimis: i 1. A yielding unit of the character despring 18 when the bars 1 and are forced scribed, comprising overlapping relatively and longitudinally slidable members; a pair of abutment members slid-ably connected with said, slidable members; a spring act- .ing injopposite directions upon said abutment members, and means for holding said slidable'me'mbers parallel independently of said abutment members. r
