To ctZZ whom it may c0ncern.-'

Be it known that I, EDWARD CLIFF, of Newark, in the county of Essex, in the State of New Jersey, have invented new and useful Improvements in Car-Trucks, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates .to car trucks, particularly street car or motor trucks and the object is to provide an easier riding car and to prevent undue vibrations thereof.

To this end my invention consists in thecombination with a stationary or lower frame supported upon the running-gear, said frame having sections extending outwardly from the axle, of a movable or upper frame supported upon said truck, spiral springs located between the said upper and lower frames, a halfelliptic spring located between each extended 1 section of the said lower frame and the upper:

frame, the axle-boxes, pedestals or yokes in the lower frames, and springs between the said axle-boxes and yokesg and my invention consists in certain other combinations of parts.

hereinafter described and specifically set forth in the claims. r

In the drawings hereto annexed and formthe axle-box, takenon line a"; a: of Fig. 2; and

Fig. 4 shows a modified arrangement of the.

spiral springs on the pedestal and axle-box.

Referring specifically to the drawings, A represents the wheels; B, the axle-boxes; O, the upperor movable frame, and D the lower, or what is sometimes termed the stationary frame. The lower frame may have its sides in one piece but they are preferably made in three parts, that is, the end portions, D", are connected together by side-beams, D, bolted or riveted thereto, the side-beams, D, being connected together by transversely extending bars, d, d, bolted or riveted to the side beams. The pedestal or yoke for each.

axle-box is preferably integral with the extended end portions of the lower frame.

D" are the outwardly extending sections or parts of the sides of the lower frame which form the bed of the extended spring base,

said sections extending outward from the pedestal some distance. The end portions, D may be made of malleable or steel castings connected together by steel bars, D, lying and bolted in sockets.

The movable or upper frame upon which the car-body rests is preferably rectangular in form and longer than the lower frame. Spring platesor sockets, c, c, are secured to the lower side of the upper frame above the pedestals on the lower frame and corresponding spring sockets, c, c, are in the upper side of the pedestals to receive spiral springs, E, extending between the two frames of the truck. 'In Figs. land 4 I show a single spiral spring above each pedestal, or two spiral springs one within the other, but in Figs. 2

and 3 a pair of spiral springs are shown side Extending vertically through the center of the springs, F, F, and through the pedestal or yoke of the frame are bolts or spring-posts,f,f. F is a detachable retaining piece extending horizontally between the sides of a yoke and below the axle-box which can be detached for the purpose of removing the said box from the yoke or frame.

' b, b are spring-hangers depending from the upper frame of the truck to receive one end of each of the end semi-elliptic springs G. These springs are located between the extensions of the lower and upper frames and the lower parts of the elliptic springs are preferably used. Each of said springs is held at its center in a frame, g, having a projection on its lower side, which enters and lies in a socket, g, on the end of an extension, D so that the frame, g, may rock slightly therein. A bolt, 9 extends through the said projection and washers on each side of the extension, D" to hold the parts securely in place. The inner ends of these elliptic springs are coupled to the lower frame by links and the outer ends yokes above the side bars, D, are the upper parts of semi-elliptic springs H. Said springs are shackled at their ends to the yokes and the central parts are held in frames, h, having projections on their upper sides which lie in sockets, h, secured to the under side of the middle of the upper frame 0. p

The upper frame, 0, may be formed by the bottom of the car-body if desired, and the spring-hangers and sockets secured thereto.

Any matters shown or described herein relative to the truck-frames and springs are not dedicated to the public, but form'the subject matter of another application filed September 8, 1893, Serial No. 485,121.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1. In a car-truck, the combination with the. lower frame supported upon the running gear,

said frame having end sections extending outwardly from the yokes and integral with% the said yokes, bars extending between the said end sections and secured in sockets therein, an upper frame mounted onsaid truck, spiral springs between the two frames, a half-elliptic spring between the extended sections and the upperframe, one end of said spring being linked to the lower frame, and its opposite end being linked to the upper frame, and semi-elliptic springs between the yokes on each side between the two frames as set forth.

2. In a car-truck, the combination with the lower frame supported upon the running gear, said frame having end sections extending; outwardly from the yokes and integral with the said yokes, bars extending between the said end sections and secured in sockets therein, an upper frame mounted on said truck, spiral springs between the two frames, a half-elliptic spring between the extended sections and-the upper frame, one end of said springbeing linked to the lower frame, and its oppositeend being linked to the upper frame, and the upper part of an elliptic spring shackled to the yokes on each sideof .the

truck, and having its central bearing lying in a socket secured to the upper frame, as set forth.

3. In a car truck, the combination of the upper and lower frames mounted upon the running gear, lower halves of elliptic springs between the endportions of said frames and having their outer ends shackled to the upper frame and their inner ends shackledto the lower frame, central bearings for said springs, and sockets in the ends of the lower frame to receive the bearings, as set forth.

4. The combination with an axle-box, a pedestal having its vertical sides remote from said axle-box, and an upper frame of a truck, of a support fora spiral sprin'goneach side of the axle-box, spiral springs between the i said supports and the upper horizontal por- -.tion of the pedestal, and between the said vertical'sides and the sides of the axle-box, bolts passing through said supports and held stationary .in the pedestal and a spiral spring between the upper side of the pedestal and the upper frame.

5. The combination with an axle-box, a pedestal having its vertical sides remote from said axle-box, and an upper frame of a truck, of a socket for a spiral spring on each side. of and integral with the axle-box, sockets in the lower side of the pedestal directly above the first mentioned sockets, spiral springs excurely in position and stationary in the pedestal, springsockets in the upper side of the frame, and spiral springs extending between the pedestal andsaid upper frame and lying in the sockets, as set forth.

In testimony whereof I have hereunto signed my name.
