SIX-WHEEL TRUCK.
Patented Feb, 12, 13113.
so that the weight is distributed substan 'tially equally on the outside and middle Wheels, whereby the riding qualities of the car are greatly improved and the amount I of repair work greatly reduced.
To these ends my invention comprises the'novel features hereinafter set forth and claimed.
In the accompanying drawing, Figure 1 is a plan view of a portion of a six-Wheel truck, partly broken away, showing my 1nvention applied thereto; Fig. 2 is a part longitudinal section of same; Fig. 3 is a section on the line 3-3, Fig. 1; Fig. 4 is a modified form of my invention; and Fig. 5 is a section on the line 5-5, Fig. 1.
In the drawing, T have illustrated my invention" in connection with a well-known form of passenger car truck-frame of the six-wheel type, said frame consisting of the wheel-pieces 2, the end-rails 3, the transoms 4, and wheel-pieces 5. The wheel-piece 2, as shown, is substantially box-shapein cross [section and comprises a top plate 10, an
inner-wall 11, an 'outer walll2f, and a bottom-plate 13. The front-wall or outer wall 12 is provided with the opening 14, which is closed ordinarily Toy-the plate 15 secured in lace by bolts 16. v
- he bottom-plate 13 is provided with the openings 17 registering with the journal- "boxesll. Supported on the journal-boxes 18 are theblocks 19, which form the supports for the ends of the equalizer-bars 20. The blocks 19 may be slightly concaved as at 21 to receive the curved end-portions 22 of the equalizer-bars.
A bolt or hanger 23 is suspended from the equalizer-bar at one side of the mid-' point of said bar. This hanger is suspended from a pin 24, which passes through a clevis 25 on the upper end of the hanger, as clearly indicated in Fig. 3. The opening 26 in the clevis 25 is slightly larger than the pin 24 to allow for a certain amount of play for the reason more fully hereinafter set forth.
The hanger 23 passes down. through-a suitable opening 27 formed in the bottompiece 13 of the wheel-piece 2, said opening being large enough to permit of a certain amount of movement of said hanger herein. A bearing-plate 28 bears against the seat 29 around the opening 27, said bearingplate having the neck-portion 30, which enters said opening. The bearing-plate 28 is provided with the opening 31 for the passage of the hanger. Surrounding the hanger is the springplate 32 held. in place by the nut 33 engaging the threaded portion 34 of the hanger. Springs 35 are interposed between the bearing-plate 28 and the spring-plate 32, the tension of said springs being controlled by the position of the nut 33 on thehanger. The springs 35 act normally to hold the equalizer-bars 20 down on the journal-boxes and by the use of said springs a'yielding' riding quality of'the car. The suspended hanger "ermits of the swinging of the same due to t is raising or lowering of the ends of the equalizer-bar; and furthermore, the equalizer-bar is contained within the truckframe, which reduces the size and weight of the equalizerrbar while, at thesarne time, it is out of the road for removal and application of brake-shoes.
,Another point of advantage of a yieldingfulcrulnof this type in the riding of the truck consists of the breaking up of the vibrations; that is, the fulcrum spring being a spring of short period of vibrationand the elliptic springs 36 under the truckbolstersbeing of long period oscillation.
In Fig. 4:, I have illustrated a modified form of my invention in which the hanger instead of having the elevis-end 25 has simply a straight end-portion through which the connecting pin passes. This construction permits of the use of an inner-plate 37 acting to strengthen or brace the wheel piece 2.
What Iclaim is: p
1. The combination with a truck-frame and its journal-boxes, of an equalizer-bar supported at its ends on said journal boxes, a hanger suspended from said equalizer-bar, and a spring interposed between an abutment on said hanger and said frame, where by a yielding-fulcrum is formed between the truck-frame and said equalizer-bar.
2. The combination with a truck-frame and its journal-boxes, of an equalizer-bar supported at its ends on said journal-boxes, a hanger suspended from said equalizerbar; an abutment on said hanger, a bearing-plate surrounding said hanger bearing against said frame, and a spring interposed between said abutment and said bearingplate, whereby a yielding-fulcrum is formed between said frame and said equalizer-bar.
3. The combination of a truck frame having a hollow wheel-piece, journal-boxes, an equalizer-bar contained within said hollow wheel-piece and its ends bearing on. said journal-boxes, and a spring-controlled hanger depending from sald equalizer-bar and forming a yielding fulcrum between said frame and said equalizer-bar.
In testimony whereof, I the said ANDREW OHRISTIANSON, have hereunto set my hand.
