`CUSHION-WHREL FOR VEHICLES.

To all fr0/wm t may concern;

Be it known that I, AUGUSTJ. MEYER, a citizen of the Unitedy States, residing at Chicago, in the county of Cook and State of Illinois, -have invented certain new and useful Improvements in CushionlVheels for Vehicles, of which the following is a speciiication. i

My invention relates to a construction of cushion wheels for vehicles which is an improvement on the construction shown in my pending application Serial Number 715717, filed August 19, 1912, and in my present construction all-of the practical advantages secured by my earlier construction are retained and improved devices `are provided for mounting and housing the cushions.

and given any desired degree of initial com# pression.

ySimilar numerals refer to similar parts throughout the several views.

sists of a rim 15 provided with a tire 16 preferably of resilient material, this rim beingvsecured to4 a ring 17 preferably of cast metal by sectors 18 riveted or bolted at 19V to flanges 20 projecting outwardly lfrom the ring 17. A felly 15a made in sections is preferably employed between the outer edges of the sectors 18 and the rim 15, all

by a sleeve 22 which carries bearings for rotatively mounting the wheel on kits support. The sleeve 22 can of course if desired be rigidly securedto the axle instead of being rotatively lmounted thereon. y

The casting 21 has formed thereon at four equi-,distant points .cylindrical bosses 23, which form the supports for the inner cushion housing members 24, each of which members surrounds the rmajor portion of two.` sides of a resilient cushion 25. Each member24 is provided with a `concave seat engaging the corresponding cylindrical boss 23 so that said member is positively heldin place by said boss and yet permitted to rock.

somewhat thereon,l there beinga sliding ac-v tion between the member and the boss for such rocking motion. The other two walls of each cushion compartmenty are formed by means of a member l26 resting against the inner surface of the ring 17 and also at one end against an arm 27 projecting axially from the/plate 28 forming one of the vside walls of the hub construction. There are four of these arms 27 and their faces adjacent the members26 are disposed so that two adjacent arms constitutek in ef-y fect a wedge'ca'rried by the casting 21 with which ther plate 2S. is integrally formed so that motion of vthe casting 21 relativelyto. thering 17 in a direction to move the armsv away from (said ring separates the adjacent members 26 somewhat and this exerts com- 27 through which an inwardly extending arm 29 projects radially from the' ring I1"( to engage a cushion bumper 80 supported Patented May 7, 191s'.

Application Ied May 6, 1916. Serial N o. 95,950.

- As shown in Figs. 1 and 2 the wheelcon `which is a metal casting supported in partv by the casting 21 between adjacent ones of the members 24. The ring 17 is also provided withinwardly projecting bosses 30a equidistant from the arms 29, which bosses are sufliciently large to have formed in them clearance openings 31 around the studs 32 projecting axially from the plate 28. An inclosing plate 33 is secured to the ends of the arms 27 and the ends of the studs y32 by'cap'sc- rews 34 and 35 as indicated. Besides the bumpers 30 the casting 21 also carries a second pair-'of bumpers 36, each of which is indicated at the innerr end of a boss 30a. As a result ofthe construction described it will appear that there are four bumpers employedl which are equidistant from each other and spaced angula'rly at equal distances between the center radial lines of the cushions, these bumpers being provided to limit the amount of radial motion that the ring 17 may have relatively to the casting 21. Any desired amount off clearance may be provided between the bumpers and coperating bosses carried by the ring 17 or if preferred no clearance at all may be used and the bumpers may be made of such material as to properly limit the radial motion referred to without said clearance. A

rlhe construction ofthe casting 21 and the relation of the disk or plate thereto, as well as the manner in which the arms 27 are formed thereon is best seen by reference to Figs. 8 and 9 which are similar to the construction shown in Figs. 1, 2 and 4 with the exception that the supporting tube 22a is formed integrally with the casting and provided with inwardly extending angular flanges 37 which may readily be bored to lit and be rigidly secured to the axle of the vehicle. In this construction a brake drum 38 is also shown' as formed integrally with the casting 21a.

At the base of each of the arms 29 an axial hole 39 is made through the ring 17 to be engaged by circular plugs 40 as shown in Fig. 2, which plugs are rigidly secured to wearing plates 41 mounted upon and secured to the ring 17 between it and the plates 28 and 33. These wearing plates are provided with clearance openings around the tube 22 and around the arms 27 and the studs 32 so that the casting 21 and the parts carried thereby may move radially and angularly relatively to said plates. Recesses 42 are formed in the inner faces of the plates 28 and 33 to contain lubricant to facilitate the free movement of the wearing plates relatively to the inclosing plates 28 and 33. Each` of the arms 29 may have holes 43 formed partly` or wholly through its inner end if desired to somewhat lighten the construction.

It will be observed that the outwardly extending ends of the members 24 diverge outwardly from the radial line through the center of the adjacent boss 30a, with which boss the' outwardly diverging surfaces are in contact, as a result of which the boss 30a acts as a wedge between the adjacent members 24 so that motion inwardly of the boss 30a relatively to the casting 21 separates the members 24, causing them to rock somewhat upon the casting 21 and compress the corresponding cushions 25. It will be also observed that angular motion of the casting 21 relatively to the ring 17 places alternate ones of the cushions 25 in compression so that the resultant of a load upon the -axle and a turning movement thereon produces e a displacement of the axle relatively to the ring 17, which is more nearly in a horizontal plane lthan in a vertical plane, and thus any tendency of the wheel to rebound when striking inequalities in the roadbed is largely or wholly overcome, since the displacement of the wheel relatively to the `axle is, as referred to, nearly in a horizontal direction.

Each of the bumpers 30 is preferably composed as indicated in Fig. 2 of av plurality of thicknesses of resilient material, such, for example, as rubber belting, and the cushions 25 are preferably made up in the same manner, although both the bumpers and cushions may be made of solid resilient material if preferred. The manner of mounting the races for the roller bearings of the wheel in the casting 21 will be best understood by reference to Fig. 4. As shown in this figure, the left hand end yof the casting 21 is bored to fit the outwardly projecting lugs formed ony ring 22, and this ring is in turn bored to'receive and support the roller race 70. The ring 2,2 has formed on it an outwardly projecting sleeve .71 surrounding the race 70, which sleeve is threaded on its outer end to engage a cap for inclosing the end of the axle. The other end of the casting 21 is bored, preferably to a somewhat larger diameter, to receive the outwardly extending lugs of a second ring 22a similar tothe ring 22, with the eXception that it has no outwardly extending flange, and this ring 22e1 yis in turn bored to receive the race 72 for the other roller bearing of the wheel. The two roller bearings ofa wheel of the kind under consideration are usually of different diameter, 'which accounts for the different diameters of the rings 22 and 22a. lt will also be noted that the boss 23 shown in Fig. 4 projecting outwardly from the casting 21 is inclined somewhat to the axis of the wheel, and that the inner surface of the corresponding cushion retaining inember24 is similarly inclined. This is to facilitate placing the cushions in position and removing them from the hub when necessary, since by this construction it is necessary to' move the member 24 but a `arms and bosses 29a and 30b being similar to the corresponding arms and bosses 29 and 30a shown in Fig. 1, the principal difference being that the inner ends o-f the bosses 30b are beveled instead lof being rounded as shown in Fig. 1. In the construction shown in Figs. 5, 6 and 7 the spokes 44 are formed as shown in Fig. 7 with outwardly anged ends so that in constructing the wheel the inner end of each spoke restsupon and around a projecting lug 46 formed on the ounter surface of thering 17a and the outer,

end of each spoke rests around an inwardlyy formed` proj ection 47 formed in the rim. The rim is preferably put in place by heating it so that it will be expanded somewhat, and for this condition the spokes are placed as indicated in Figs; 5 and 6, and then the ends of the spokes are secured to the rim and ring by some form ofV welding, preferably by means of the Oxy-acetylene flame. As 1 shown in Fig. 10, `it is advisable in practice to provide protecting shoes 48`between the members 24a and 26@ and the cushions 25SL to inclose the otherwise open corners of the cushion. These shoes, it will be understood,` retain the cushion in place and prevent it being squeezed out through the corners referred to without in any way interfering with the cushioning action referred to above. The edges of the shoes are preferably thinned down toa sharp edge as indicated to afford no opposition to the slight motion` of the cushion relatively to .them during the cushio-ning operation. These protecting shoes are not shown in Fig. 1 for the sake of clearness, and yet it will be understood it is desirable-to use them in, connection with that construction. i

In the m'odiied construction shown in Fig. 3 springs are employed instead ofthe cushions abovedescribed. In this construe tion the casting 21b is provided with recesses for receiving the inner ends of the springs 49, which serve as bumpers between the casting 21b and the arms 29? extendinginwardly from the ring 17?, the ends of these springs beingso conformed that they are normally subjectedto torsion tending` to rotate the casting 211 in a direction counter clockwise to the ring 17h. Similar bumper springs 5() kare disposed between the casting 21b `and the bosses 3()C extending inwardly from the ring 171. Betweeny each pair of bumper springs 49 and 50 aseat is formed on the casting 21b for receiving a sliding member 51 provided with outwardly extending arms 52 and 53 having lugs 54 and 55 for-engaging and holding in place one of the cushion springs 56 and 57 respectively, the other ends of these springs being engaged and retained by lugs 58 and 59 carried by the sliding member 26b mounted inside of the ring 17b and in sliding engagement therewith, andheld in place by the arm 27` projecting from the casting 21b in a manner `similar to the construction described above for the casting 21' and the arms 27. The springs 56 and 57, be-

sides having a suitable initial compression to support the load, are also subjected initially to a torsional stress tending to move the sliding member 51 radially away from the ring 17h to assist in the cushioning operation.- ' Ihe sliding members 51 and 26b operate when the axle is subjected either to a load or a turning movement, or both, in substantially the manner that the members 24 and 26 operate as described above, the principal difference being that springs of the kind describedl are employed instead of` the cushions 25. The member 51 is provided with a lug 60 extending into a recess 61 formed in the outer surface of the casting 21h, the edge of this recess and said. lug cooperating to limit the sliding motion that may be imparted t0 the member 51. While but one complete cushioning construction is shown in Fig. 3, it will be unden stood that four of said combinations are employed in connection with the complete wheel, and that two of each of the bumper springs 49 and 50 are employed in said com- `plete construction.

provided with four seats for receiving the inner ends of the bumpers 30e and-36, the outer ends of which are engaged by the inner ends of the arms 29 and 7 3, respectively. rIhe spaces between the resilient bumpers 30e and 36c are filled with triangular blocks 74 of resilient material which are provided with protecting metallic shoes 75. The bumpers 30e and 36c are provided with metallic protecting shoes 76 and 77, respectively. The-outer` surfaces of the shoes 7 5v are engaged by the inner supporting members 24?, forming the cushion compartments which .compartments are completed by the outer members 26". The spaces between the ends of the inner and outer members 24 and 26c are incased lby the protecting shoes 48, which serve to holdin place in the cushion compartments the resilient cushions 25.

The axial arms 27, which, as above described for the construction shown in Figs. 1 and 9, are rigidly secured to the central casting, engage the outer surfaces of the inwardly extending converging walls of the outer members y26e and these arms serve as wedge members for moving the members 26 from each other when the inner member of the hub is moved relatively to the outer` member in a radial direction along the vertical axis, as shown in Fig. 11. The arms 73, of which but one is shown in Fig. 11, are provided near their inner ends with wedge shaped surfaces for engaging the outwardlyextending diverging walls of the inner members 24k@ of the cushion supports so that radial motion of the members of the hub construction relatively to each other along the horizontal axis shown in Fig. 11 separates the members 24Cc from each other. Any displacement of the members of the hub construction relatively to each other, it will be observed from the above description, produces a compression upon the cushions 25C, which in turn is communicated to the resilient blocks V741, and by them in turn to the lateral faces of the resilient bumpers 30e and 36, which bumpers are also subjected to radial compression by the arms 29c and 73. I nd in many cases that this combined action of the resilient bumpers is effectively produced by the resilient cushions by the interposition of the resilient triangular blocks referred to. The arms 7 3 are provided with clearance openings 31 through which the studs 32c extend for holding the side plates of the hub in place substantially as described above in connection with Fig. 1. i

In the construction shown in Fig. 12, the operation is in a general way similar to that produced by the construction shown in Fig.y

11, the difference being that the triangular blocks 74 of resilient material are omitted and instead the resilient cushions 25d yare extended so as to occupy the combined space of the resilient cushions and triangular blocks shown in Fig. 11. In the construction shown in Fig. 12, the outer cushion supports 26d are extended from just inside the ring 17d inwardly toward each other and, when in close proximity to the bumpers 30d, they extend parallel to eachother to form the inclosing lateral walls of the bumper construction. Similarly, the inner supports 24d are continued from their outwardly diverging ends inwardly parallel to each other to form the lateral supports for the resilient bumpers 36d. The axial arms 27d and the inwardly extending arms and bosses 29d and 7 8 are substantially of the same construction and operate in substantially the same manner as do the corresponding parts found in the construction shown in Fig. 11. As a result of constructing the cushions as shown in Fig. 12, it will be observed that :any compression of any one of the cushions exerts lateral thrusts upon the adjacent resilient bumpers which tend to equalize al1 shocks to the greatest' possible degree. 'lhe protecting shoes 48d and the studs 32d are of substantially the same construction and for the same purpose as the corresponding parts shown and described vin connection with Fig. 11. In Fig. 12 there isalso shown a modified construction for securing spokes 14d to the ring 17d. In this construction, outwardly extending hollow studs 46d are secured to the ring 17d and these studs 'are provided with i'ianges 7 9 of larger diameter than the outer diameter of the body portion of the studs, which body portion is of a diameter substantially the same as the inner diameter of the spokes 44d. The flanges 79 are of substantially the thickness of 'the wall of the spokes i4-d, so that as a result of the parts having substantially the same heat conductivity-the fusing of the parts together by the Oxy-acetylene flame is facilitated. It will be understood that but one spokefis shown in Fig. 12 for the sake of clearness, but that it practice a plurality of regularly spaced spokes is employed in substantially the manner shown in Fig. 5.

In Fig. 13 there is shown a construction to facilitate assembling the cushions in place, which construction permits giving the cushions any desired degree of initial compression. In this construction the end plates S0 and 81 are supported from the sleeve 82, which sleeve may be rotatably mounted upon a stationary axle or rigidly secured to a rotary axle in `any desired manner not shown. The outer surface ofthe sleeve 82 is threaded, as indicated, to receive a taper nut 83 having'a conical outer surface which ts the inner surface of the cushion supports 84. The outer surfaces of the cushion sup-ports 84 may be formed substantially as indicated in Figs. 1 and 6 and provided with end walls for engaging the ends of the cushions in substantially the manner shown and described in connectionwith said figures. I do not limit kmyself to constructing thesupp'orts 84 in this manner, however, as the mechanism yshown in connection with this construction for holding the cushion supports in place may be employed for other forms of cushion supports. Sliding'plates S5 and 86 are located between the end plates 80 and 81 and the cushions to inclose the cushion compartments, and the outer surfaces ofthe cushions yare supported by the cushion supports 87 resting on the inner surface of the'hub ring 88 in substantially the manner above described. As a result, the cushions 89 are properl heldin place and the inner supports may lie moved outwardly to any desired degree by screwing the conical nut 83 into the supports upon the sleeve ing the holes 90 provided for that purpose.

When it isdesired to take up any lost mof tion that may result from wear, it issimply necessary to screw the conical nut 83 somewhat farther into the cushion supports 84, and a key 91 .is provided engaging suitable keyways in the outer surface of the sleeve 82 and the inner surface of the nut 83 to hold the nut in desired adjustment. When it is desired to remove the cushions and replace them, the conical nut 83 is un material having a proper degreeof elasticity and resilience and that the cushions and bumpers may either be formed in solid blocks or built up as desired.

It will ybe understood that I do not limit myself to the specific construction described above in carrying out my invention; for example, the supports for the cushions may be somewhat differently formed if preferred,

and the shape of the cushions may be correy spondingly changed as long as the supports, the axial arms and inwardly extending bosses coperate in substantially the manner described to compress the cushions when there is a displacement of the inner and outer members relatively to each other. Throughout the claims I refer to the inner and outer supports each constituting two adjacent walls of the cushion receptacle since the receptacles are shown in the drawings yas having four walls, but it will be understood that this phraseology includes other constructions of supports aslong as the inner and outer supports together substantially inclose the edges of the cushions. Similarly changes may be made in the other features of my construction without departf 4ing from the spirit of my invention.
