CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 471,912, dated March 29,1892.

Application filed December 6, 1891. Serial No. 414,162. (No model.)

To all whom it may concern:

Be itknown that I, JOHN TAYLOR, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Oar-Trucks; and I do hereby declare that the following is a full, clear,

and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a half side elevation and half centrallongitudinal section of acar-truck embodying my improvements. Fig. 2 is a half end elevation and a half transverse section of the truck. Fig. 3 is a plan view of the truck. Figs. 4, 5, and 6 are detail views of the cornercastings detached. Fig. 7 is a detail of the motor-bar hanger. Figs. 8, 9, and 10 are details of the bottomjaw-stays. Fig. 11 is a detail sectional view of the corner jaw-braces. Figs. 12 and 13 are detail views of a modification of the end bars. Fig. 14 is an enlarged side View showing the body supporting springs. Fig. 15 is a detail of the motor-bar hanger.

The objects of thisinvention are toimprov the car-truck for which Letters Patent No. 437,167 were granted to me on thev23d day of September, 1890; and the present invention consists in simplifying and strengthening the main frame, improving the construction of the jaw stays and braces, the springs, and motor-suspending devices, and in certain other novel details of construction and combination of parts, as will be clearly understood from the following description and claims.

In the drawings the side beams A of the truck-frame are each composed of two parallel metal bars a a, set vertically edgewise and,

securely united by bolts or rivets, being kept apart by interposed sleeves on the bolts or castings, substantially as in my patent referred to above. The jaws B B, which'embrace the boxes, are securely bolted to said beams, as shown.

0 represents the corner-castings, secured to theextremities of beams A. Said castingshave rabbeted c c in their sides to receive the ends of bars a a, and the upper edges of said bars are rabbeted, as a a, to accommodate the upper flanges of castings 0, so that when fitted .together the outer side and top faces of the it and hereinafter referred to.

beams and castings are flush. The castings are secured in place by bolts A, which transfix the same and bars a a. The castings have extensions 0' on their inner extremities, lying between the bars and terminating in an inclined socket G the top of which is closed, but has an adj usting-bolt G tapped through Above socket O is formed a transverse sleeve 0 which lies between bars a a and through which is passed a bolt A securing the same rigidly to the beam. The castings in turn form a connection between the component bars of the beam. The extensions 0 have side flanges O on their lower edges, which underlie the lower edges of bars a a, as shown in Figs. 1 and 2. The castings also have depensions O at their outer edges,in which are two transversely-inclined openings 0 O for the reception of the ends of transverse truss-rods F, and below these openings are bolted the fender-hangers c c, as shown.

The end bars D D of the truck-frame are preferably of flat metal and are rigidly united to the corner-castings O C of opposite side beams, as shown, the ends of bars D being fitted into the angles formed at the junction of depensions C with the main body of the casting, which may also be slightly rabbeted, as at O to receive the extremities of the bars, and being secured to the castings by bolts D D, which pass through vertical openings in the castings O, as shown at each side of bolts A. v

O are webs uniting depensions C with the main body of the castings. By this construction a strong and stiff framing is produced.

E E are the body-supporting springs, as shown, of elliptical form, mounted transversely of and upon barsD near the side beams A, being bolted thereto, and underneath these springs are double-truss-rod chairs f f, which are clipped or bolted to the under surface of bars D, and the bolts that secure the chairs may be utilized for securing the springs to the bars, if desired.

F F are truss-rods lying beneath bars D andupholding chairs f,the ends of said rods passing through openings 0 in depensions O of the castings C, as shown, thus forming strong transverse trusses for the bars D and an additional connection between the beams.

ICO

G G designate the body-bars or bolsters, lying above bars D and supported on springs E E. I preferably make these bolsters of wood when the trucks are used with electric motors, as 'an additional insulation between ear-body and truck-frame is maintained thereby, and rubber or otherinsulation may be interposed between the bolsters G and ironwork of the truck, as indicated at g g. When the wood bolsters G are employed, should the springs E E vary in height the car can be leveled by cutting it out for the reception of the springs where necessary, and as few springs are of exactly similar height this enables an easier fitting of the car-body on truck'springs to be made than where metal body-bars are used.

To the center of bolsters G are secured depending sockets G, which telescope with smaller sockets G secured centrally to bars D below, and through these pieces pass the bodysecurin g king-bolts G on thelower ends of which are retaining-nuts G coiled springs (l being interposed between the nuts, washer, and bars D to make a cushioned connection between the body and truck. The lower ends 7 of bolts G and the springs thereon have free play between the pairs of truss-rods F F, as indicated in Fig. 1, so that thebolts can be readily removed or adjusted without interfering with the trusses. The car-sills g are connected to bolsters G by hanger-straps g".

The jaws B B are of ordinary construction, except that opposite upwardly-inclined sockets B are formed at their lower outside corners to receive oppositely-inclined braces B as shown. Braces B" are exterior, and their upper ends enter the sockets O of castings (J, respectively, and may be adjusted by bolts C or by bolts B, tapped through the bottoms of sockets 13 as shown in Fig. 11. It is not necessary to have adj Listing-screws in both sockets B or C and hence when bolt 13 is used bolt C may be omitted. In Fig. 11 the latter is used. The upper ends of braces B enter sockets 7), formed in the ends of castings b b, bolted between bars a, a, and may be adjusted by bolts 11 tapped therethrough, as shown.

The car-axle boxes H II are fitted in jaws I3, as usual, and the lower ends of the jaws are closed and united by stay-castings I I, which have shoulders I 1 fitting against the inner edges of and between the legs of the jaws, and are secured thereto by bolts 1 which pass through horizontal flanges on the jaws behind sockets 13 B On the inner ends of stay-castings I are formed Sockets 1 1 which receive the ends of horizontal stays J J, which thus form a connection between the jaws. One or both ends of stays J J are threaded and nuts J are screwed thereon, and after the stays are in place these nuts are unscrewed, thereby abutting against the sockets and bind it between the jaws and keep the latter properly separated. Preferably I employ tubular rods or pipes for stays J.

K K are transverse metal straps bolted to collars K K on stays J and lying transversely of the truck near to the jaws. These straps prevent the lateral spreading apart of the op posite jaws when the truck is thrown violently to one side, as in rounding curves, and they also answer as supports for the pan or hood, protecting the motors from dust, 850., when motors are suspended on the trucks.

L L designate transverse bars suspended centrally from and between beams A A and designed to uphold an electric motor. These bars are suspended by loops or U-bolts L, which embrace the bars and pass through openings in castings M, bolted between the members of beams A, as shown in Fig.7, said castings having top lips M, which catch on the upper edges of bars a a. Bolts L engage notches L in the loweredges of the bars L, and thus longitudinal movement of said bars is prevented, while castings M prevent lateral vibration thereof. (See Fig. 7.)

O designates the motor-suspending plate, which is attached to the centers of the bars L by L-shaped clip-bolts O, which are riveted or bolted to the bars L, as at 0.

In order to lower the truck frame, if desired, and where roller-bearin gs are employed in the axle-boxes, I form thesprings as shown in Figs. 1 and 14ca half-elliptic spring P, bent into approximately Cupids-bow shape, the shorter leaf 1) being lowermost and its ends curving down. The superimposed leaves are bent at center to correspond with the lowest leaf; but their extended extremities are gradually and successively given an upward bend, so that the ends of the topmost leaf 1) rise above the center thereof and are formed into eyes 19 19 which are connected to the hangers Q Q by bolts 13 The springs are thus kept below the tops of beams A. and play between the members thereof. I-Iangers Q Q depend between bars a a and have rocking nuts q on their lower ends,which coact against washerplates q, clipped to the beams, and by which means the beams and truck-frames are suspended on the axle-boxes. When the ordinary aXle-bearings are used, the ordinary semi-elliptic springs may be employed.

In Fig. 13 I have illustrated the end bar as formed of channel-iron, substantially as in my patent referred to, and trussed up by rods like the flat end bars hereinbefore described. The ends of the truss-rods in this instance pass through the depensions on the castings and through the ends of fender-hangers, so that their nuts confine the latter in place. These truss-rods greatly stiffen the end bars and enable them to be made much lighter than would be practical if they were not trussed.

Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is-

1. The combination of the side beams, the end bars connected to the extremity of said beams, and the double parallel truss-rods underlying said bars and connected to thebeams,

and the chairs interposed between said rods and bars, substantially as described.
