UNITED STATES PATENT OFFICE.

CLARENCE VERNER GREENAMYER, OF LOS ANGELES, CALIFORNIA, AS- SIGNOR OF ONE-HALF TO ALBERT P. GROSS, OF SAME PLACE.

CAR-BEARING ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 594,359, dated November 23, 1897. Application filed July 16, 1897. Serial No. 644,837. (No model.)

To aZZ whom it may concern.-

. Be it known that I, CLARENCE VERNER GREENAMYER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful General Oar-Bearing Adjuster, of which the following is a specification. I

This invention includes an attachment for railway passenger-coaches, sleepers, and any and all other vehicles riding on a truck and equalizing-bars.

The equalizing-bars above referred to are in pairs, one upon each side of the truck in the case of four-wheeled trucks and two upon each side of the truck in the case of six- Wheeled trucks, and the ends of each equalizing-bar rests upon journal-boxes and are carried by the brasses of such boxes. The equalizing-bars bow downward between their ends below the level of the brasses, and the springs which sustain the car rest upon the intermediate or lower portion of the equalizing-bars. It is important that the equalizingbars shall move independent of each other to prevent racking by low joints in the track. A difficulty heretofore experienced with the brasses of trucks having equalizing-bars, is the tendency of the brasses and the journals to wear unequally. The portions of the faces of the brass and journal which are nearestthe wheel wear more rapidly than the portions which are nearest the ends of the axle. This unequal wearing soon causes the journals to heat, so that the brasses have to be renewed as often as every four or five days of steady run and the axles have to be renewed quite frequently, though not so frequently. as the brasses. This involves a very great expense, and the object of my invention is to avoid this wearing and consequent expense. This I accomplish by tying the equalizing-bars together by a connecting device which allows independent movement of the bars, but me vents them from spreading apart under the pressure of the springs. The equalizing-bars may be tied together by various means and in various ways without departing from the spirit of my invention, and I will not attempt to illustrate all of the forms in which this invention may be carried out.

My invention also includes a tie for equalizing-bars of car-trucks adjustable both as to length and position of attachment to the equalizing-bars and torsionally automatically adjustable to the independent rocking action of either equalizing-bar.

The accompanying drawings illustrate my invention in several modes of its application.

Figure 1 is a perspective view of portions of a car-truck provided with my invention. The ends of the boxes are broken to show the brasses. Fig. 2 is a cross-section of the same. Fig. 2" is an enlarged sectional detail showing the set-screw in the countersunk hole. Fig. 3 is a detail of another form of tie. Fig. 4 shows another form of tie. Figs. 5 and 6 show other forms of tie which I deem less desirable than the forms shown in the other views.

My invention comprises the combination, with the brasses A and the equalizing-bars B B of a tie to prevent the bars from spreading apart under the pressure of the carsprings.

C O, &c., indicate different forms of ties. Preferably the tie is adjustable as to length and is also swiveled. The purpose of adjusting the tie as to length is to enable the mechanic to bring the equalizing-bars into a perfectly plumb position and hold them in that position, so that the pressure upon the brasses will hold the brasses with their faces true to the bearing. The purpose of swiveling the tie is to allow enough twisting of the tie to give freedom for independent motion of the equalizing-bars, so that the ends may rise and fall independently. The tie is also preferably adjustable along the length of the equalizingbars, so that the tie can be attached exactly at the middle of the equalizing-bars, for the reason that the tie is most eflective and is subjected to the least strain when attached to the bars at the middle thereof.

The tie O, which is shown in Figs. 1 and 2,

is swiveled, is adjustable as to length, and is also adjustable along the equalizing-bars. Said tie is also connected to the equalizingbars by a non-rigid connection-that is to say, the connection is made by akind of hook with set-screws, whereby the bars are prevented from spreading apart, but are allowed in some degree an independent motion.

2 indicate two rods connected by a turnbuckle or half-turn buckle 3.

1 indicates a head on one of the rods to hold it in the turnbuckle, or, more properly, the half-turn buckle 3, through one end of which the rod 1 is passed. The rod 2 is screwed into the other end'of the turnbuckle and is held in position lengthwise the bar by the jamnut 2.

c 0 indicate two stirrups fastened to the outer ends of the rods 1 and 2, respectively, and adapted to clutch over the opposite equalizing-bars B B.

4 indicates a pointed set-screw to set into a countersunk hole I) in the equalizing-bar to hold the stirrup in proper position on the equalizing-bar.

In constructing this form the rod 1 will first be inserted through the hole in the end of the half-turnbuckle 3, with the head of the rod inside the turnbuckle, and the stirrup c is then welded on the end of the rod. The rod 2 is welded to the stirrup c and is screwthreaded at its opposite end and the jam-nut 2'screwed thereon. Then the rod is screwed into the end of the turnbuckle 3. Then the stirrups are placed in position on their respective equalizing-bars and the turnbuckle turned to draw them against the bars. The set-screws 4 are then screwed into their seats in the bars and the turnbuckle tightened to bring the bars into a plumb position, so that the brasses are true to the axle. Then the jam-nut is screwed against the turnbuckle.

In the form shown in Fig. 6 the stirrups c are U-shaped, and the tie-bar 5 is a single rod, which is passed through the free ends of the stirrups and fastened with nuts 6. This form is liable to break just inside the equalizing-bars. Adjustment can be made by screwing the nuts.

In the form shown in Fig. 4: the tie is composed of a rod 7, connected by eyebolts 8 with stirrups on the equalizing-bars. In the form shown in Fig. 5 the tie is formed of two rods 9 9, connected at the center by eyes 10 on the ends of the rods.

Fig. 3 shows two rods 11 11 connected by a swivel 12. t

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

1. A car-bearin g adjuster comprisinga pair of equalizing-bars tied together by a connecting device which allows independent movement of the bars, but prevents them from spreading apart under the pressure of the springs.

2. The combination with the brasses and the equalizing-bars of a tie connecting the equalizing-bars at the middle thereof to prevent the bars from spreading apart under the pressure of the car-springs.

8. The combination of the equalizing-bars and an adjustable tie connecting the bars.

4. The combination with the equalizingbars of a swiveled tie connecting the bars.

5. The combination with the equalizingbars of a swiveled and adjustable tie connecting the bars.

6. The combination of the equalizing-bars; stirrups, one on each of the bars and adjustable, therealong; means for fixing the stirrups in place on the bars; and a tie connecting the stirrups together.

7. The combination of the equalizing-bars on the brasses of a truck; a swiveled tie and means for adjustably fastening the ends of the tie to the bars.

8. A tie for equalizing-bars of car-trucks adjustable both as to length and position of adjustment to the equalizing-bars and torsionally automatically adjustable to the independent rocking action of either equalizing-bar.
