CAR-TRUCK.

PECFICATON forming part of Letters Patent No. 350,923l dated October 19,1886.

Application filed May 4, 1886. Serial No. 201,079. (o model.)

.T0 all whom, it 72mg/ concern:

Be it known that I, DANIEL W. Francs, a citizen of the United States, residing at Constableville, in 'the county of Lewis and State of New York, have invented certain new and useful Improvements in Car-Trucks, of which theA following is a specification, reference being had therein to the accompanying drawings.

rIhis invention relates to certain new and useful improvements in car-trucks; and it has for its'tobjects, first, to provide an improved arrangement of wheels, whereby displacement from the rails shall be precluded, and yet of such a nature that the wheels may follow the curvature ofthe track; second, to provide for supporting the cars at both sides, so as to prevent lthe lateral sway incident to the present construction and connection ofthe trucks with the cars, and, third, to provide an improved rail peculiarly adal'ited to the arrangement of the truck-wheels.

In the accompanying drawings, forming a part of this specification, and on which similar letters of reference indicate the same or corresponding features, Figure I represents a plan view of the frame-work of a car, mounted upon two of my improved trucks; Fig. 2, a front view ofthe same; Fig. 3, a detached sectional view of a pair of wheels, and Fig. 4, a sectional view ot' a portion of a frame and of a rail, showing the brake mechanism in elevation.

The letter A 4designates the side and intermediate beams of a car-frame, and the letters B and B lcrossbeams thereof, the several beams being connected together in any approved manner.

To the beams B are pivotally connected by a king-bolt, C, the side beams, D, of the trucki'rames, which consist, preferably, of timbers of sufficient length and measurement in crosssection to withstand the strain incident to their functions. It will be observed that these side beams of the trucks are connected with the car-frame near the sides of the latter, as distinguished from being connected at the longitudinal center of the frame. The result of this construction is,that the cars are support` ed at each side, and the swaying tendency overcome, since by this construction the body cannot be rocked from side to side. The nanse ating effects of this objectionable action ofrail- Waycoaches is well known, and I overcome this objection by my construction. Suitable springs, of course, may be employed.

The truck-beams of each truck are connected together by the transverse bars E by apivotal connection, so as to keep them in proper relative position, yet to admit of their turning on their respective king-bolts. To each beam is fitted a yoke, F, consisting of a strong iron structure,through which the beam passes, and t0 which it fits snugly on the upper and under sides, while a space is left at either side to admit of the yoke being turned without regard to a movement of the beam. Each yoke is secured to the beam by a king-bolt, G. Projecting from either side of each yoke is an axle-spindle, the direction of which is at an angle ot' about twenty-five degrees. Upon these spindles I mount wheels H with regular faces, as distinguished from flanged wheels, the angle ofthe wheels being about sixty-tive degrees. They are prevented `from slipping ott' the spindles in any convenient manner-in the present instance by a pin, I, with a washer, J, interposed between it and the hub-and a cap, K, is secured to each hub with an oil-space between its interior and the pin and washer. The caps are screwed or otherwise secured, and a quantity of oil placed therein is found to work its way gradually to the interior of the hub and keep the spindle in a lubricated condition.

The rails are of peculiar construction, as shown clearly in Figs. 2 and 4, and consist of three wings, L, two of which rest upon the ties and form the bearing -surl'aces for the wheels on their upper faces,while the third or upper wing serves to guide the wheels and prevent their dislodgment from the rails. The distance between the wheels at their nearest point is slightly greater than the thickness ofthe wings L at their thinnest point, and the increased thickness of the wings at the edges acts to positively prevent the wheels from j u mping the track. The wheels,by reason of their angular position with respect to each other and to the upper wing, are prevented from engaging or impingi ng against the upper edge of t hat winO. It is also noticeable tha-t the rails may be turned so as to present different wearing-surfaces to IOO pendent of the trucks.

the wheels as occasion may require, which effects a saving in the keeping of the road-bed in order. l

In connection with this peculiar rail I have designed a brake, which consists of two levers, M, pivotally connected to abracket extending from one ofthe truck-beaxns,and having shoes at their lower ends, which engage and bind against the sides ofthe upper wing of the rails when their upper ends are separated by the action of a pivoted lever, N, and a connectingrope or chain, O. A'movement of the lever N in the direction of the arrow draws the portions I and P of the rope in the opposite direction, the portion P passing over ash eave, Q,-and acting to draw the adjacent lever in that direction. The lever VNis designed to be actuated by any of the known brake appliances, which are not illustrated, as they form no part of this invention.

I desire to observe that this invention is an improvement over Letters Patent granted to D. WV. Eames, July 1, 1851, No. 8,197. In this patent trucks are shown having sets ofwheels obliquely disposed to the rails; but the axles of the wheels do not have a movement inde- Having thus fully descr1bed my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a truck secured rigidly to the car-frame,of wheels placed at opposite`sides of each rail and mounted at an angle to the rails, movably connected with the truck, and adapted to change their positions with`respect to the truck to accommodate themselves to curvatures.

2. The combination, with a car -truck, of

Wheels placed at opposite sides of each rail l and mounted at an angle thereto, and connected with the trucks so as to vary their positie with respect thereto.

3. rIhe combination, with a cartruck,ofwheels mounted in pairs, one of each pair being placed -at opposite sides of each rail and connected with the truck so as to change their position with respect thereto.

4. The combination, with the truclbbeam,

of a yoke which embraces the beam and is piv-v otally connected therewith,and provided with spindles at its opposite sides and placed at an angle to each other, and wheels mounted upon said spindles and standing at an angle to each other.

5. The combina-tion, with a car-frame, of a truck providedfwith wheels placed at an angle to the rail, the truck having its side beams connected to the outer portions of the frame.`

'6. The combination, with a car-frame, of a truck provided with Wheels placed at an angle to the rail, the truck having its side beams pivotally connected with the frame and with -each other.

7. The combination, .with a ear-frame, ot' the truck, the outer beams of which are pivotally connected with said frame, and truckwheelsmounted at an angle to the rails and adaptedto have a movement independently of the truck.

8. The combination, with the wheels mounted at an angle, of arail having two treading-surfaces and a portion disposed between the wheels 9. The combination, with wheels associated in pairs and mounted at an angle to each other and having Hat surfaces, of rails having a surface for the tread of each wheel and an intermediate portion.

In testimony whereof I aiix my signaturein presence of two witnesses.
