GEORGE M. BRILL, OF PHILADELPHIA, PENNSYLVANIA.

RUNNING-G EAR FOR RAILWAY-CARS.

EBPECIPICATION f rming part of Letters Patent No. 357,811, dated February 15, 1887.

Application filed July 9,1886.

T ctZZ whom it may concern:

Be it known that I, GEORGE M. BRILL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Running- Gears for RailwayOars, of which the following is a specification, reference being had therein to the accompanying drawings, wherein-- Figure l is a side elevation of the lower part or sill-pieces of a car and its running-gear embodying my invention. Fig. 2 is a detail section on line 1 1, Fig. 1. Fig. 3 is a like view on line 2 2, Fig. 1. Fig. 4 is an end view of Fig. 1, partly broken away; and Fig. 5 is a section on line 3 3, Fig. 1, drawn to an enlarged scale.

My invention has relation to the runninggear and brace or truss rods for streetrailway or other cars of the form having a brace or truss rod for the axle-boxes, springs, and pedestals, which brace or truss rod connects with or has its ends fastened to the sill or other timbers of the car-body; and it has for its objects to make the brace or truss rod in sec tions bolted or otherwise secured together, so that one or more sections, or those between the pedestals, are removable from the other sections, to provide for displacing or taking an axlebox, car-wheels, and axle, or any other of its appurtenant parts, off of the car-body for repairs or replacement, or for other purposes, without removing the entire truss or brace rods.

My invention consists of the combination, construction, and arrangement of parts, as hereinafter described and claimed, having reference particularly to a sectional brace or truss bar connecting the pedestals with and having its ends secured to the sill pieces or timbers of the car'body, and to an axle-box having fixed depending yokes straddling or embracing the trussrod adjacent to stops or projections on each side of the brace or truss rod, for said yokes to abut against and prevent side movement of the axle-box.

In the drawings, A. represents the lower or sill timbers of a car-body; B, the wheels; 0, the axle-boxes; D, the pedestals or upright rods connecting the brace or truss rod E with the sill-timbers, all of which, except the truss Serial No. 207,552. (No model.)

or brace rod, may be constructed and put together in any desired way.

The truss-rod E is made in sections, and

one end are bolted at c to the central section, e,

and at the other end are bolted at e to bent sections or rods 6, fastened to the sill-pieces of the car body. The sections 6* may be a single rod or end for the truss or brace rod E, as indicated by dotted lines, Fig. 1, or it may be a double, forked, or similarly-formed section, one part, 6, of which aligns with the brace or trussrod E and fastens to the longitudinal sills, and the other part, a bends at right angles to truss-rod E and fastens to the crosstimbers of the car-body, as shown more plainly in Fig. 4. By unscrewing the bolts or fastening devices e and thepedestals or rods D, the sections 6 ofrods E fall or may be taken out to remove an axle box or boxes, a car-axle, and wheels without disturbing the connections of the remaining parts or sections of the trussrods E.

The truss-rod sections 0 may be provided, if desired, with suitable upright stay bolts or braces, Gr, connected to or abutting against the sill-pieces for firmness and strength, and for supporting section 6 when either or both sections e are removed.

Any suitable arrangement of springs H for the car between it and its axle-boxes may be employed; but I prefer to use a combinat-ion of rubber and spiral springs, h h, respectively, as shown more plainly in Fig. 5,wherein the rubber springs it rest upon side platforms or brackets, c, on the axle-box, and have upper caps, c, supporting the spiral springs h, the tops of which are held in place or enter caps 13, between which and the sill-plates 73 are other rubber blocks or springs, '5 the pedestals or bolts D passing down through central or axial openings in said springs and caps when said bolts are used.

The caps 0' have downwardly-projecting tubular sleeves or plungers c slightly taperin g on the outside. These plungers pass down.

through the rubber spring or block openings, and bolts D pass through the sleeve or plunger opening. The openings 0 in axle-box brackets c are' made large enough to receive the lower ends of the plungers 0 which ends therefore terminate below the bottom of the rubber springs h, and do not come in contact with the latter as the car vibrates or sways in its travel, and all chafing, wearing, or other deterioration of the rubber springs h by the plungers or sleeves c is avoided. The springsupporting pins or studs 0* on caps 0, being central or within the mandrel-holes of the springs h, prevent accumulation ofdirt or dust on the lower bearings of said springs as the dirt works out over the top edges of the caps. The relative arrangement of the rubber blocks or springs and spiral springs gives a soft and easy motion for the carbody.

If desired, small rubber blocks a may be placed between the truss-rod E and axle-brackets c, to take up the wear and shocks of the axle-box against the truss-rod.

To prevent side -thrust of the axle-boxes, they are formed with depending yokes or lugs k, which embrace the truss-rods between side stops or lugs, it, formed on said rods. The latter form stop-pieces for the axle-box yokes 7c and stop any side motion of the boxes.

The truss-rod lugs may be outside of the axle-box yokes k, as shown to the right of Fig. l and in Fig. 2, or they may be between the yokes, as indicated to the left of Fig. 1 and in Fig. 3.

As the detailed improvements above described are susceptible of use in connection with or on any sorm of axle-box and arrangement of spring-supports for the car, and with various configurations of pedestals, I do not confine myself to the form and arrangement of said parts as shown. So, too, the side braces, e may be used with a non-sectional truss-rod E.

What I claim is- 1. A sectional truss-rod, E, substantially as and for the purpose set forth.

2. A sectional truss-rod, E, having axle-box or pedestal sections bolted to the remaining sections of the rod, so as to be removable from one another without disturbing the fastenings for said last-named sections, substantially as Set forth.

3. The truss-rod E, composed of sections removable from one another and having side braces, 6 substantially as set forth.

4. The truss-rod E, having side braces, 6 substantially as set forth.

5. The sectional truss E, having stay bolts or bars G for its central section, 6 substanor bearings between the spiral and end springs,

substantially as set forth.

8. The combination, with a car-axle box, of truss-rod E and rubber blocks a between the box and rod, as and for the purpose set forth.

9. The combination of truss-rod E, having on each side lugsk, andaxle-box 0, having depending yokes 7c, straddling or embracing the truss-rod adjacent to its lugs, substantially as set forth.

10. The combination of asectional trussrod, E, having side lugs, 7t, and axle-box O, having depending yok'es 7c, straddling or embracing the truss-rod adjacent to its lugs, substantially as set forth.

11. In combination with a car-axle box having a bearing or plate, 0, with central aperture, c stay bolt or rod D, of less diameter than aperture 0 cap 0, having a tubular plunger, 0 depending into aperture 0 and spring h between said bearing and plate, substantially as set forth.

12. In combination with a car-axle box, a plate or bearing, 0, rubber block or spring on said plate, and a cap, 0, having plunger 0 passing through said spring and plate, as and for the purpose set forth.

13. In combination with axle -box 0, the bearings 0, cap 0, having plunger 0", rubber block or spring h, spiral spring H, cap i, sillplatei, and rubber block or spring i substantially as set forth.

14. In combination with a car-sill plate and axle-box, a spring-support comprising a lower and an upper rubber block, an intermediate spiral spring, and caps or plates between the spiral and rubber springs, substantially as set forth.

15. In combination witha car-axle box and a rubber block or spring supported by the box, a cap for. the rubber block having a plunger passing through the block and into the boxsupport for the block, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
