THOMAS BELL MACKEY, OF DALLAS, TEXAS.

RUNNING-GEAR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 309,067, dated December 9. 1884.

Application filed September 20,1884. (No model.)

To on whom, it may concern- Be it known that I, T. B. MAOKEY, of Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Running-Gear for Street and Railway Cars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a top View of my improved run hing-gear for street or other railway cars. Fig. 2 is a bottom view of the same. Fig. 3 is a side view, and Fig. 4: is a perspective view, of the running-gear, showing it used for a common wagon or similar vehicle.

Similar letters of reference indicate corre sponding parts in all thefigures.

My invent-ion has relation to running-gear for vehicles, especially adapted for street or other railway cars; and it consists in the 1111 proved construction and combination of parts of the same,ashereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate two parallel bars or sills,connected by crossbars B, and forming a frame upon which the vehicle bed or box is supported, and to the forward end of which the draft is applied, a single-tree, 0, being shown in the place for attaching the draft. The rear ends of the longitudinal sills project beyond the rear cross-piece, and a sliding cross-bar, D, fits and slides with two slots, E E, upon the said ends of the sills,and has two flanged rollers, F F, journaled at its ends,which rollers are adapted to bear against the peripheries of the hind wheels. The wheels G are mounted upon the axles H, which revolve in boxes I, of the same construction as shown in the patent granted to me on the 30th day of January, 1883, No. 271,487, and which are provided with antifriction rollers, which bear against anti-friction tables or disks in the same manner as in the aforesaid patent. the said rollers and disks being shown at J and K in the drawings.

L L are the rear hounds, which are secured near their rear ends to the rear bolster, M,

and the forward ends of these hounds are slotted longitudinally at N, while a cross-bar, O, connects the hounds near their forward ends. The forward hounds, P P, are secured near their forward ends to the forward bolster, Q, and their rear ends are connected by means of cross-bars R R, secured at their ends to the upper and under sides of the hounds,and connected by means of vertical bolts S S, which project through the slots in the rear hounds, the said hounds sliding with their slots upon these bolts. Connecting-rods TT are attached to the ends of the cross-bar O,which connects the forward portions of the rear hounds, and at their forward ends the said connectingrods are attached to two levers, U, pivoted upon the forward bolster; and it will be seen that by tilting eitherof the levers the corresponding end of the cross-bar of the rear hounds and the hind wheel at that side will be drawn forward, thus enabling the truck or running-gear to turn a curve with ease. Springs V V are secured at one end to the forward ends of the rear hounds, and at their rear ends to the cross-piece connecting the rear ends of the forward hounds, and the said springs serve to force the rear hounds rearward when either of them or both have been drawn forward by the levers U. Two pairs of rollers, W WV, are mounted upon the ends of two rods, X X, and travel upon the rear ends of the rear hounds and upon the middles of the forward hounds, having the longitudinal sills A A traveling upon them, and springs Y Y serve to connect the sills and the bounds, preventing the sills from sliding off from their position upon the rollers. Springs Z Z are attached to the cross-bar connecting the rear portions of the longitudinal sills and to the cross-bar D, sliding upon the rear ends of the said sills, and serve to draw the said crossbar and its rollers against the hind wheels when draft is applied to the frame formed by the sills, and at the same time prevent the rollers upon the sliding cross-bar from bearing too hard against the rims of the wheels. It will thus be seen that the draft is neither applied to the running-gear directly nor to the vehicle bed or box, but to a frame sliding between both, thus easing the pull for the team; and it will also be seen that asthe draft becomes harder, and consequently the frame is drawn farther forward, the rollers will bear against the hind wheels and apply the draft directly against their rims, which will relieve the draft upon the forward portion of the truck, and place the greater portion of the same upon the rear portion of the truck and upon the hind wheels, which will cause the draft for the animals to be comparatively easier than where the draft is directly upon the forward portion of the running-gear or vehicle bed or box. It will also be seen that where the running-gear is used for street or other railway cars the distance between the front and hind wheels may be made comparatively longer than between the wheels in the usual construction of trucks, on account of the hind wheels being capable of being drawn closer toward the front wheels at either side of the truck, which will allow the truck to pass around curves, which a truck having the same distance between the wheels and having the axles secured rigidly would not be able to pass; and by making the distance between the front and hind wheels greater the car mounted upon the truck or running-gear will have a longer support and be less liable to bob up and down at the ends, as they are liable to where the trucks have to be constructed with short space between the front and hind wheels, on account of the sharpness of the curves of the road. All disagreeable and uncomforta ble motion is thus avoided in this construction, as well as jars in starting or stopping the vehicle, the sliding frame traveling between the body and the running-gear of the vehicle preventing them, the runninggear thus making an agreeable and easy addition to a vehicle for the passengers as well as for the draftanimals.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination of the running-gear of a vehicle and a frame traveling longitudinally above the running-gear, having the draft attached to its forward end, and having rollers at its rear end adapted to bear against the rims of the hind wheels, as and for the purposeshown and set forth.

2. The combination of the running-gear of a vehicle, having longitudinal hounds, a frame having longitudinal sills and having the draft attached to its forward end, rollers traveling between the sills of the frame and the hounds, and a cross-piece attached to the rear end of the frame, and having rollers upon its ends adapted to bear against the rims of the hind wheels, as and for the purpose shown and set forth.

4.. The combination of the rear portion of the running-gear of a vehicle, having longitudinal hounds provided with longitudinal slots at their forward ends, and the forward portion of the runninggear having longitudinal hounds connected at their rear ends by cross-bars having vertical bolts projecting through the slots in the rear hounds, as and for the purpose shown and set forth.'

5. The combination'of the rear portion of the running-gear of a vehicle, having longitudinal hounds provided with longitudinal slots at their forward ends, the forward portion of the running-gear having longitudinal hounds connected at their rear ends by crosspieces, and having bolts projecting through the said slots, springs attached to the forward ends of the rear hounds and to the said crosspieces, and means for drawing either or both of the rear hounds forward, as and for the pur pose shown and set forth.

6. The combination of the rear portion of the running-gear of a vehicle, having longitudinal hounds provided with longitudinal slots at their forward ends, and connected at the said ends by means of a cross-bar, the forward portion of a running-gear having longitudinal hounds connected at their rear ends by cross-bars secured to their upper and un der sides, and having vertical bolts projecting through the slots, spring s attached to the forward ends of the rear hounds and to the cross pieces of the forward hounds, connecting-rods attached to the cross-bar of the rear hounds at both ends of the same, and levers'pivoted upon the forward portion of the running-gear and having the forward ends of the connecting-rods attached to them, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

THOMAS BELL M AGKEY.
