SPECIFICATION forming part of Letters Patent No. 497,829, dated May 23, 1893. Application Iiled October l0, 1892. Serial No. 448,373. (No model.)
T all whom t may concern:
Be it known that I, THOMAS K. SHEA, a citizen of the United States, residing at Cincinnati, in the county of IIamilton and State of Ohio, have invented certain new and useful Improvements in Cars; and I do declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to improvements in cars for streetrailway and similar purposes and the object is to support and carry the body of such cars in a new manner whereby its jolting and jarring is greatly lessened and they are caused to ride more easy on their wheels or trucks and afford greater comfort to the passengers therein. This is substantially accomplished by interposing additional springs between the running gear or trucks and the body and by disposing the former near the top of the body which latter is swung or hung on these springs.
In the following specification is found a full description of my invention, the same being also particularly pointed out in the claims at the end thereof and its construction illustrated in the accompanying drawings, in which- Figure 1, is a side-elevation of a car provided with my improvements, parts of one of its sides broken out. Fig. 2, is a vertical crosssection of the same, the plane of said section passing through a line fyy on the near side of the car and through a line oc-x on the far side of the car. Fig. 3, is a perspective view of a part of the frame which supports the car-body, showing the springs connected in a modified manner.
6, are suitable wheels secured upon axles 7, which carry bearings or boxes 8, at their outer ends. Braces 9, secure these boxes to a rail 10, which connects all the wheels or trucks.
11, are customary springs resting on the trucks and supporting the super-structure of the car in the well known manner.
I do not limit myself to the construction of the trucks as described thus far and desire the same to be regarded merely as a type for many others which are adaptable for this purpose.
Supported by truck-sprin gs 11, are uprights 5 5 12, held in position thereon in any suitable manner but preferably as shown, which is by passing them loosely through a slot in rail 10, and by providing thexn with a base 13, which t-s over boxes S. free to vert-ical vibration and adjustment on springs 11.
14, is an oblong frame, corresponding substantially in its dimensions with the length and width of the car and 12, to which it is rigidly secured. This frame sustains the roof of the car and also the top of the sides which consist of an inner and outer casing 15, and 1G, respectively.
17, are rods extending downwardly frame 14, and are provided at their lower ends with round plates 1S, which form rests for coil-springs 19. 20, are other plates resting on top of these springs and connected to the Thus said uprights are 6o from 7o bifurcated ends of rods 2l, which support 75 the floor-sills 22. These sills support the door 23, of the car and also the lower part of the sides which consist of an inner casing 24, and an outer one 25, which with their upper ends reach between casings frame 14.
It will be observed that all jars and jolts to which the wheels are subject will pass through the modifying action of two springs 15, and 16, affixed to 8o before reaching that part of the car which di- 8 5 rectly supports the passengers. Whatever of the jarring motion of the wheels is notbroken by springs 11, before it reaches uprights 12, will be almost neutralized by springs 19, be-
fore it reaches the lower part of the car which 9o hangs on these latter springs. During these vibrations the lower part of the car swings independently on the upper part and the lower part of the sides 24., 25, slide or telescope resting on uprights""6`5` within the upper part 15, 1G, so that at all 95 y,
times the sides of the body are completely connected and closed.
In Fig. 3. the skeleton or frame which supports the two parts of the car is shown. Ob-
long frame 14, is the part which sustains the roo top and upper parts 15, 16, of the sides and rods 21, and sills 22, are the parts which sup- Y.the omission of port the car-floor and the lower parts 24, 25, of the sides. The inner part or casing24, passes to and meets floor 23, while the outer part 25, for the sake of better appearance passes pref-V erably below the floor-sills 22, so as to cover their ends. In this latter figure theeonnection of the springs 19, has been modified by the spring-rests 18, and 20, and the two ends of the springs connect directly to rods 17, and 21, or to trame 14, and rods 21. Y
Having explained my invention, Irclaim as new- 1. An improved construction for cars, oonsistingof the combination of wheels or trucks, uprights restilng thereon, an independent upper part ofthe car supported on these uprights, and consisting of the oar root and upper parts of sides an independent lower part of the car, consisting of floor and lower parts of sides elastic or spring-supports interposed between upper and lower parts for sustaining these lower parts, the two parts of the car slidingr or telescoping within each other, all as substantially shown and described.
2. An improved construction for cars, consisting ot' the combination of wheels or trucks, uprights resting thereon, a frame 14, snpported by them, an independent upper part of the car resting on said frame, rods or supports which sustain an independent lower part of the car and the floor of the same and springs interposed between the two parts of the car, all as substantially shown and described.
3. An improved construction for cars, consisting of the combination ot' wheels or trucks,
uprights resting thereon, a frame 14, supported by them, an independent upper part of the car resting on said frame, rods 17, and 21, secured to frame 14, an independent lower part of the car supported by said rods and springs interposed between these rods, all as substantially shown and described.
4. An improved construction for cars, consistingof the combination of wheels ortrucks, uprights resting thereon, a frame 14, supported by them, an independent upper part of the car resting on said frame, rods 17, having rests 18, depending from said frame, springs 19, supported on rods 17, bifurcated rods 21, having a rest 20, which rests on springs 19, and an independent lower part of the car including its Hoor, supported by rods 21, all as substantially shown and'described.
5. An improved construction for cars, consisting of the combination of wheels or trucks, uprights resting on them,a frame 14, resting on these uprights and having secured to it the upper part of the sides of the car which consist of a double casing 15, 16, elastic supports depending from frame 14, an independent lower part of the sides sustained by said supports and also consisting of a double oasing 24, 25, which in conjunction with the upper part of the sides incloses and hides all parts of the frame and construction, all as substantially shown and described.
6. An improved construction for cars, oonsistingot` the combination of wheels or trucks, rails 10, connecting them, springs 11, resting on the trucks, uprights 12, supported on springs 11, and guided by rails 10, an independent upper part of the car resting on uprights 12, an independent lower part of the car supported on the upper part and springs interposed between the two parts of the car, all as substantially shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
