UNITED STATES PATENT OFFICE.
IVILLIAM KOEDDING, OF ST. LOUIS, MISSOURI.
CAR-TRUCK.
SPECIFICATION forming part of Letters Patent No. 495,894, dated April 18, 1893.
Application filed July 6,1892. Serial No.439,l67. (No model.)
To all whom it may concern;
Be it known that I, WILLIAM KOEDDING, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Oar-Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to certain improvements in car trucks, intended more particularly for use on street-cars; and my invention consists in features of novelty hereinafter fully described and pointed out in the claims.
Figure I is a top or plan view of my improved truck. Fig. l[ isa side elevation, showing part of the car body broken away. Fig. III is a vertical, detail section of the track brake, taken on line III-III, Fig. IV. Fig. IV is a similar view, taken on line IVIV, Fig. III. Fig. V is a view similar in all respects to Fig. IV, but showing the parts in a different position. Fig. VI is a perspective view of the track brake head which'holds the shoe that bears upon the brake. Fig. VII is a transverse section taken on line VIIVII, Fig. VIII, and showing my invention as ap plied to a pivotal truck. Fig. VIII is a Iongitudinal section, taken on line VIIIVIII, Fig. VII. Fig. IX is a bottom view of the upper member of the fifth wheel of a pivotal truck; and Fig. X is a top view of the lower member of the fifth wheel.
Referring to the drawings, 1 represents part of a car body. 2 represents the track wheels; 3 are the axles of the track wheels, and which are journaled in the usual boxes 4. 5 represents a truck frame, to which my invention in part relates. The frame is composed of an upper chord or member 5, and a lower chord or member 5 on each side of the car; the upper and lower chords on each side of the truck are connected together by vertical end portions 5, by vertical, central portions 5, and by vertical axle box portions 5. The axle boxes fit between the vertical connecting portions 5 and are thus held in the frame, as shown clearly in Fig. II. 5 represents strips or bars secured to the lower chord 5 beneath the axle boxes. Projecting from each end of the lower chord is an arm 5 to which the usual guard of street cars may be secured.
I have described one side of the truck frame,
the other side being a duplicate of it. Each side is cast with all of the parts which I have enumerated in one piece, so that there is no danger of the parts becoming loose, and so that the frame is perfectly strong and durable. The two side parts which thus constitute the frame are connected by cross bolts or rods 6, of which there may be any suitable number, and from which the wheel brake mechanism is suspended, as hereinafter explained.
The car body is supported on the truck frame 5 by means of bolts 7 secured to the body or to plates 8 which are made fast to the body; said bolts passing down through the upperand lower chords of the frame and surrounded by springs 9 between the upper and lower chord, and upon which bear disks or washers 10 secured to, or formed upon the bolts 7, so that the depression of the bolts will cause the compression of the springs.
To prevent oscillation of the car body, I connect the body to the upper chord of the frame by means of bolts 11,which pass down through the upper chord of the frame, and which are surrounded by springs 12 located between nuts or washers on the lower ends of the bolts, and the upper chord of the frame, as shown clearly in Fig. II.
13 represents the removable shoe or die of the track brake supported in a head 14, (see Figs. II, III, IV, V and VI.) The head of the shoe is pivoted at 15 to a vertically moving block 16, held in a sleeve or cylinder 17, which is made fast, as shown at 18 to the lower chord of the frame 5, and to an extension 19 on the lower chord of the frame.
20 represents a rock shaft journaled to the upper ends of the sleeves or cylinders 17, (there being a sleeve or cylinder 17 on each side of the truck frame,) and to this rock shaft is secured an arm 21 to which the brake rod 22 is made fast. On the rock shaft are projections 23 connected by links 24 to the block 16 of each brake-shoe, as shown at 25, Figs. IV and V. The lower ends of the links 24 are slotted to receive the pin 25, and it will be understood that when the shaft 20 is rocked in one direction, the brake-shoe will be forced downwardly upon the truck by one of the links 24, and when the rock shaft is moved in the other direction, the brake shoe will be forced down by the other link 24; the slot in the link which is not being used to produce the pressure, simply moving on the pin 25 so that this link does not interfere with the movement of the brake shoe by the other link.
26 represents springs for lifting the brake shoe from the track when the rock shaft is brought to a position of rest; the lower ends of these springs bearing against the bottom of the projections 19, and their upper ends bearing against the projecting ends of the pins or against blocks 25 fitted on the projecting ends'of the pins 25, (see Fig. III.)
27 represents the shoes of the wheel brakes. These shoes are suspended by links 28 from the upper connecting rods 6 of the truck frame.
29 are the beams of the brake shoes 27, (see Fig. VIII.)
30 is a lever pivoted at 31, and to which the pull rod 32 of the wheel brakes is connected.
33 is a rod connecting the far beam 29 to the lever 30, and 34 are links connecting the lower end of the lever 30 to the near beam 29.
35 is an arm secured to the pivot 31, and which is provided with a spring 36 for holding the shoes from the wheels when the brakes are not applied.
In Figs. VII to X, I have shown the invention applied to a pivotal truck, in which 40 represents the bolster, upon which rests a disk 41 having an annular groove 42 to receive friction balls 43. 44 represents a disk secured to the car body, and which rests upon the balls 43. 45 represents the king or connecting bolt. The pivotal point between the truck and the car body is thus constituted of a ball bearing.
The bolster 40 is preferably composed of an inverted angle iron, as shown clearly in Fig. VIII, which fits over a lower beam 46 secured to the car truck by means of bolts 47 passing down through the upper chords of the truck frame, and provided with springs 48 which fit between nuts or washers on the lower ends of the bolts and disks 49 made fast or secured to the bolts 47 directly beneath the upper chord of the frame.
For the purpose of preventing lateral oscillation of the car body, in the use of the pivotal truck, I connect the outer ends of the beams 40 and 46 by means of bolts 50, surrounded by springs 51, and to guard against end vibration of the car with the piv-v otal truck, I provide the bolster 40 with lateral extensions 52 from which depend bolts 53 that extend down through the truck frame, and are provided with springs 54 between washers 55 fitting respectively against the inner surfaces of the upper and lower chords of the frame, and which are made fast to the bolts 53.
If desired, the shaft 20 may be provided with a sleeve 20 surrounding itbetween the two sides of the truck frame, and to which the levers or arms of the brake rods may be secured, as shown in Figs. II and III.
I claim as my invention- 1. A car truck frame having side members, each consisting of an upper and lower chord, having connecting portions and guard extensions cast integral; substantially as set forth.
2. The combination, in a car truck, of the side members, bolts connecting the side members, a track brake, a block to which the shoe of the track brake is pivoted, a rock shaft, means for moving the rock shaft, slotted links connecting the rock shaft to said block, and a housing or cylinder in which said block moves; substantially as set forth.
3. The combination in atrnck frame, of the brake shoes 14, a block 16 to which the shoes are pivoted, a rock shaft, arms 23 on the rock shaft, and slotted links 24 connecting said arms to said block;substantially as set forth.
4. In a pivotal car truck, the combination of a truck frame, a bolster 40, a grooved disk secured to said bolster, a disk secured to the car body, friction balls adapted to fit between said disks, a beam 46, and spring bolts connecting said beam 46 to the truck frame; substantially as and for the purpose set forth.
5. In a car truck, the combination of a truck frame, bolster 40 secured to the car body, spring bolts 51, a beam 46 secured to the truck frame, and spring bolt 53 connecting the bolster 40 to the truck frame; substantially as and for the purpose set forth.
6. In a car truck, a frame composed of an upper and lower chord, axle box, portions 5 cast integral with the upper and lower chords, said upper and lower chords having seatscast upon them for springs 9 and 12; substantially as and for the purpose set forth.
