Weston, Box 146, Klamath, Calif. Filed Sept. 13, 1963, Ser. No. 308,788 4 Claims. (Cl. 104-119) The present invention relates to rolling equipment generally and in .particular to a wheel assembly for -a monorail.
An object of the present invention is to provide a `"wheel assembly which is useful for railroads, overhead or surface, or for such overhead supports as doo-r hangers, `amusement devices, roller coasters, and the like.
Another object of the present invention is to provide a wheel assembly for a monorail [which is sturdy in construction, one having ya minimum of friction when rolling, p
and one which is highly effective in action.
A Yfurther object of the present invention is to provide a wheel assembly for a monorail which lends itself to ease lof maintenance, one which has long life characteristics, and one which is economically feasible. These and other objects and advantages of t'he present invention will be fully apparent vfrom the following description when taken in connection with the annexed drawings, in which:
FIGURE 1 is an elevational View partially in section of a first embodiment of the present invention, portions being shown broken away,
lFIGURE 2 is a view taken on the lline 2-2 of FIG- URE 1,
iFIGURE 3 is a side elevational view of the locomotive portion of -a train employing the wheel of the present invention, the dotted line showing indicating the wheel assembly and the related driving mechanism,
FIGURE 4 is a view on an enlarged scale, taken on the line 4-4 of FIGURE 3,
FIGURE 5 is an elevational view of a modified form of the invention, .shown on a rail, the rail being shown in section,
FIGUR-E 6 is a View similar to FIGURE 5 of a further modiiioa-tion of the present invention,
FIGURE 7 is a View similar to FIGURE 5 and FIG- URE 6 of a still further modification of the present invention,
lFIGURE 8 .is an elevational view of a still further modiiication of the pre-sent invention, and
FIGURE 9 is a view in section yof an overhead monorail railway car showing how any one of the forms of the invention may be employed to support the railroad car.
Referring in detail to the drawings in which like numerals indicate like parts throughout the several views, in FIGURES 1 and 2, the numeral A10 designates generally Ia rail having a substantially cylindrical head 12 and a truncated web 14 supporting the head 12.
The device of the .present invention, in a iirst embod'- ment, consists in a pair of driving wheels 16 and 18 mounted on the lower ends of vertical shafts 2i) and 22, respectively. The .wheels 16 and 18 are identical and will be described with reference to the whee'l 16.
The wheel 16 is provided with an upper portion .24 contormably shaped to a portion of the rail ihead 12 and has a ilower portion 26 conical and shaped to tit against :the Iweb 14 adjacent the junction of the web l14 with the head 12. The shafts 20 and 2-2 are supported in bearing `blocks 28 which are slidably movable on a support plate 30 so that the wheels 16 and 18 may be moved toward and away from the rail 10.
A bearing .block 32 projects upwardly and is secured to each end of the support plate 30 and is provide-d with internal threads for threadablly engaging an adjusting bolt 34 which has its lfree end keyed to t-he `adjacent block 28 by means of a removable key 36 as` shown in FIGUR-E l. i
A frame (not shown) supports a motor 38 of which the shaft 20 is the motor shaft and another motor 40 of which the shaft 22 is the motor shaft.
Depending from the support plate 30 on each side of a slot 42 are bearings 44 in which is journaled a shaft 46. Mid-length of the shaft 46 is a roller 48 having its `1nid-portion conformably shaped to t-he upper portion of the rail head 12 as shown most clearly in FIG- URE 1.
One roller 48 and its support components is positioned forwardly of the driving wheels 16 and 18 and another one, as shown in FIGURE 2, is positioned rearwardly of the driving wheels 16 and 18.
In FIGURE 3 there is shown and designated generally by the reference numeral 50 a locomotive which might employ the wheel assembly above describedbut in which, for purposes of illustration, there is a modified form of the invention 4as shown in FIGURE 4.
In FIGURE 4 the numeral 52 designates generally` the driving mechanism for the locomotive 50 and it is seen to include driving lwheels 16 and 18 as previously described with Areference to wheels 16 and 18 and which are drivably engageable with a rail 10. The roller 48 is omitted in this `version of the invention and a suitable gear train, as at 54, drivably connects the Wheels 16 and 18' to a source of motor power 56 such as an engine or the like.
In FIGURES 5 to 8, inclusive, other Wheel and rail assemblies .are shown which may be substituted for the previously described zwheel assemblies and the associated rails. 'In -FIGURE 5, the rail 10 is provided with a substantially square head 58 and the drive wheels 60 have an upper portion 62 conformably shaped to tit the head 58 and a lower portion 64 conformably shaped to tit the adjacent part of the web 66 of the rail 10".
In FIGURE 6 the -rail 10 is shown having a square vhead 68 against which a mid-portion 70 of the driving ywheel 72 bears. Flanges 74 and 76 overlie the head 68 and the ilange 74 bears against the adjacent port-ion of the web 78 of the rai-l 10".
In FIGURE 7 a further modified form of the invention is shown in which the rail 10 is identical to the rail described ywith reference to FIGURE 1 and FIGURE 2 and in W-hich the wheel assembly comprises identical Wheels 80 having mid-portions 82 conformably shaped to iit the yhead of the rail 10 and cylindrically walled portions 84 designed to bear against the adjacent portion of the web of the rail 10. Because the cylindrically walled portions 84 bear tl-atly against the web of the rail 10 the wheels 80 are canted at .an angle so that their upper ends converge toward each other. The wheels 80 are mounted in -frame members 86 in any conventional manner.
In FIGURE `8, another assembly is shown in which wheels 88 have an upper portion 90 conformably shapedto tit the head of the rail 10 below the mid-line thereof.
Each wheel 88 has a lower portion 92 engageable with the adjacent part of the web of a rail 10.
This form of the invention includes a roller 94 supported on a shaft 96, the roller 94 engaging the upper portion of the head of the rail 10 for support of the frame 98 in the conventional manner.
In FIGURE 9, t-he reference numeral .100 designates generally a monorail railway car employing a wheel assembly 102 of one of the types or similar to that illustrated above. Additionally, each of t'he Wheel assemblies heretofore described may be employed with overhead doors, monorail systems where the rail is laid upon the ground, roller coasters, or in any mechanism requiring support of a carriage on a rail.
3 While only preferred forms or embodiments of the in- -vention have been shown and described, other embodiments of the invention may be made and practiced andl numerous changes -and modifications may .be made in the invention Without departing from the spirit thereof as set forth in the appended claim-s.
