Car Truck.
No. 49,400. r Patented Aug, 15, 1865.
y, y UNITED STATES PATENT OFFICE.
c. E. HALL, or NEW YORK, n. Y.
IMPRovr-:D CAR-TRUCK.
To all whom it may concern:
Be it known that l, G. H. HALL, of New York, in the county and State of New York, have ivented a new and useful Improvement in Oar-Trucks 5 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, forming a part of this specilication, in Which- Figure lis a plan. Fig. 2 is a side elevation. Fig. 3 is a transverse vertical section through one of the wheels in the line a' ofFig. 2. Fig. 4 is avertical section through one of the wheels in the line y y of Fig. 1 and Fig. 5 is a transverse central section through one of thewheels in the line w w of Fig. 2.
Like parts are indicated by the same letters in all the drawings.
The nature of my invention consists, first, in attaching the front and rear wheels in pairs to bars 1), pivoted to and arranged parallelwith the sides of the frame, so that the said wheels may be free to move independently of each other, either verticallyr or progressively, to accommod ate themselves to the irregularities, undulations, or windings of the track second, in casting the iron frame A B C E, upon which the car rests, in one piece, as hereinafterdescribed, so as to be not only cheap in construction, but also very stift and durable; third, in constructing the truck-wheels with au annular groove each side of a central partition, O, for the reception of two sets of anti-friction balls, to receive the vertical pressure or the weight of the car, and also the lateral pressure of the wheels, said balls rolling in the grooves on an enlarged fixed axis or drum and against a washer on the outer side of the wheel and the expanded surface of the said bars D D on the opposite side; and,fourth,in making each alternate ball ofthe series of friction -balls atrifle smaller, so that when the smaller ball, placed between two larger ones, comes in contact with them, there will be no sliding friction on the pointsof contact, (the smaller ball movin gfreely in the opposite direction to the two larger ones, asshown by the arrows in Fig. 4,) whereas if all the ballswere of the same diameter (as hitherto employed Where a series oi' anti-friction rolls `have been` used) the surfaces of any two coniing in contact would move in opposite directions, and consequently produce a great amount of sliding friction.
To enable others skilled in the art to make and use my invention, I will now proceed to describe the construction and operation of the same.
The truck-frame I make of iron, cast in one piece, as shown in Figi, consisting of two side pieces, C C, united by the curved ribs B B, A being the center, provided with a hole for the reception of the kin gbo1t, and E Etwo central arms, the ends of which are provided with sockets for the reception ot rubber springs ff, on which the center of the body of the car is supported.
D D are the two bars or plates, of cast or malleable iron or othersuitable metal, the shape of which is clearly shown in Figs. l and 2, being attached to the sides CG of the frame by means ot strong bolts or pivots G G, or their equivalents, the inner ends ot which are provided with? screws and nuts h. i
I I are cylindrical sockets for the reception of rubber springs to support the two sides of the car body, said sockets being attached to the bars I) I) by means of the pivots G G, as shown in Figs. 1 and 2, so as to be susceptible., ot a slight vibration in casethesaid bars conforming to the irregularities or undula of the track, move out of parallel with th ,y tom of the car. .l
L L L L are the four wheels of the truc which are attached in pairs, one at thelfro and one at the rear ot' each of the bars D D, on fixed axles, so as to turn independentlyiof each other. These iixed'axles I constructeither as represented in Figs. 3 or 5. In Figgli` the axle consists of a cylindrical cup, of castirou or other suitable metal, permanently attached` to the side of the barD by means of thescrei` bolt J and nut a, a being a ange, `wh ,f answers the purpose of a washer to keepfthe wheel from coming oli'. InFig. 3 onehal of the hub consists of a hollow drum,K, castiupoii; the side of the bar D and extendinglfnear half-way through the wheel, or to thel partition O, the other half of said drum beinglreiinovat ble,and consisting of an external disk orwaslier, M, and hollow cylinder N. rIhrough the center of the disk or washer M and partition O is a roundhole for the reception of the bolt J, by means of which and the nuts P and a the disk M and the wheel itself are prevented from coming o".
The wheels L L L L are made ot' cast-iron, with a smooth annular groove or rabbet each side of the central partition, O, as shown in Figs. 3, 4, and 5, for the reception of the hard metallic balls R and r, the relative size and arrangementofwliich I have already described. The rollers R are a trifle larger than the rollers r, as represented in Fig. 4, and for the object specied above. By thus substituting rolling friction for rubbing, both to support the Weight and to resist all lateral pressure,I effect a very considerable saving of power required to draw the car, as well as the expense of lubrication.
Having thus described the nature of my invention, what I claim as new, and desire to secure by Letters Patent., is-
1. Attaching the front and rear wheels in pairs to the bars D D, arranged parallel with and pivoted to the sides ot' the truck-fraine, substantially as set forth, and for the purpose described.
`2. The iron frame A B C E, on which the carrests, cast in a single piece, substantially as and for the purpose described.
3. A truck-wheel with an annular groove each side of the central partition, 0, in combination with two sets of anti-friction balls, a fixed axle, and side Washers, and the ironframe A B C E, substantially as and for the p described.
4. In a series of friction-balls, the arrangement alternately of larger and smaller balls when combined with a truck-frame, substarr tially as and for the purpose described.
5. The hollow axle S, provided With an outer ilange, n, in combination with the bars D, truckwheels, and an ti-friction balls and truckframe, substantially as and for the purpose described.
6. The removable part N of the axle and the Washer M, cast in one piece, in combination With the truck-Wheel L and antifriction balls and truck-frame, substantially' as and for the purpose described.
