CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 784,837, dated March 14, 1905.

Application filed November 7,1904. Serial No. 231,659.

To all whom it may concern.-

Be it known that I, EDWARD CLIFF, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

The invention relates to improvements in car-trucks, and pertains more particularly to the bolsters and means for connecting the ends of same to the side frames of the truck; and the said invention consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of the invention is to improve the truck as a whole and to provide a highlyeflicient truck-bolster with means for securing the ends of the same to the side frames in such manner that the latter may not shift laterally from the bolster or even become loose due to the effect of curving, one object of the invention being to preserve the squareness of the truck and secure the many benefits consequent to that condition.

The nature and objects of the invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a top view, partly broken away, of a truck constructed in accordance with and embodying the invention. Fig. 2 is a transverse section of same on the dotted line 2 2 of Fig. 1. Fig. 3 is a side elevation of same, the wheels, axle-boxes, and like parts being omitted. Fig. d is a vertical section on the dotted line 4 4 of Fig. 2. Fig. 5 is a bottom view of a portion of the body-bolster with the side-bearing rub-iron in position thereon. Fig. 6 is an edge view of same. Fig. 7 is a detached perspective view of one end portion of the bolster. Fig. 8 is a sectional view of same on the dotted line 8 8 of Fig. 7, and Fig. 9 is a top view of same.

In the drawings, 10 designates the sideframe of the truck, and in the present instance this frame is of the usual diamond type, comprising an upper arch-bar 11, alower arch-bar 12,

and a tie-bar 13, these bars being of wellknown form and construction.

The bolster is designated by the numeral 1 1 and is in one integral casting, having heads at its ends adapted to engage and be secured by the column-bolts 16 to the side frames 10. The bolster 1 1 comprises the bottom 17, sides 18, and transverse partitions 19, which connect said sides and are integral with the bottom 17. The partitions 19 subdivide the bolster into a series of compartments 20, 21, and 22, all of which are normally open at their upper ends, by reason of which the bolster in respect of said compartments may be easily cast and withdrawn from the sand, thereby avoiding in respect of the said compartments coring and like operations. The compartment 21 is rectangular in outline and has a raised seat 23 surrounding the opening 2A for the king-bolt, and upon this seat 23 are placed the four coiled springs 25, upon which is placed the cap 26, whose upper surface afl'ords the center-bearing 27 and whose sides are of rectangular box-like form and guide within the vertical walls of the compartment 21, the said sides being extended downwardly along the outer sides of the springs and being normally free of said walls.

The compartments 20 are adjacent to the side frames 10, and they also are rectangularin outline and formed with seats 28 to receive the sets of coiled springs 29, there being four springs in each of the compartments 20, corresponding with the springs in the compartment 21. Upon the sets of springs 29 are placed the caps 30, whose sides are of box-like form and extend downwardly along the outer sides of the springs 29 and guide within but are normally free of the vertical walls of the compartments 20. Upon the upper ends of the caps 30 are formed the segmental raised side bearings 31, which cooperate with the rub-irons 82, carried by the body-bolster 33, these rub-irons 32 being of segmental outline adapted to the side bearings 31 and having at their opposite edges the downwardly-extending segmental flanges 3A to pass downwardly upon the opposite edges of the side bearings 31, as shown in Fig. 2, so as to preserve the proper relation of said side bearings and rubirons to each other. During the swiveling action of the body-bolster 33 the rub-irons will move upon the arc of a circle upon the side bearings 31, but will be prevented by the flanges 34: from moving laterally off of said side bearings.

The compartments 22 are also of rectangular outline and are open at their upper ends, and they are provided with openings 35 in their bottom for the escape of dust and water.

The heads are wider than the main body of the bolster, and they extend from the ends of the bolster proper between the upper and lower arch-bars 11 12, the said heads 15 at their opposite side edges (looking at the side of the truck) being cored out for lightness, as shown by the dotted lines in Fig. 3 and solid lines in Fig. 2, and affording the upper and lower horizontal sections 36, in contact with the upper and lower arch-bars 11 12 and adapted to receive the column-bolts 16, which pass through said sections 36 and also through the bars 11 12 13 of the side frames. The opposite side portions or columns of the heads 15 (looking at the side of the track) are designated by the numeral 37, and these portions 37 are only open at their outer ends, being closed at their inner and upper and lower ends and outer and inner sides, and the said portions 37 are connected at their outer and inner sides with each other by the webs 38 39 and outwardly-extending section 40 of the bolster, the section 10 being about on a level with the bottom of the ends of the bolster and being integral with the webs 38 39. The webs 38 39 below the sections 40 are arched, as shown in Figs. 2 and 3, and the said webs above the said sections 420 are recessed or concave, as at 41 12, Fig. 2, these recesses extending downwardly from the upper arch-bar 11 and the recess 12 being deeper than the recess 41. The sides of the caps 30 adjacent to the recesses 12 are also recessed, as at 13, and these recesses 11 12 13 are provided to enable the convenient inspection from the outer side of the side frames of the springs 29 below said caps 30. Below the springs 29 the seat 28 therefor contains vertical openings 14 (indicated by dotted lines in Fig. 2,) and these openings,while permitting water and dust to escape, also admit of the introduction of atorch up through them when it is desired to inspect the springs 29 through the openings or recesses 41 42 13. The torch may be introduced to the compartment through the arched opening at the lower portion of the webs 38 39 while at the same time the inspector is observing the springs 29 through the aforesaid openings 11 42 13. The portions or columns 37 are inte gral with the webs 38 and 39 and with the body of the bolster, the body of the bolster and the heads 15 on the ends thereof being one integral casting. The portions or columnposts 37 of the heads 15 have upon their upper and lower ends the gibs or flanges 45, which engage the opposite side edges of the arch-bars 11 12 and prevent any lateral movement of the bolster or any shifting of the side frames therefrom.

The bolster is preferably cast with suitable lugs 46 for the brake-hangers.

In the drawings the springs 29 are shown as being under the pressure of the car-body and its load, and the purpose is to cause each of the sets of springs to take about one-third of the load at each truck in lieu of locating the load on the center plate. The caps 26 somewhat loosely lit the compartments 21 20, so as to allow sufficient lateral thrust when necessary, and I deem it of special advantage that the said caps and compartments are of rectangular outline and that the springs 25 29 are of about equal strength and arranged in rectangular sets and to take about equally the car-body and its load.

The bolster above described is adapted for application to any of the usual diamond trucks, and it will be observed that the heads on the ends of the bolster strengthen the side frames, that the truck-frame is held rigid and square by the bolster and its heads, and that the column-bolts secure the side frames, bolster, and heads together.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a ear-truck, the side frames having upper and lower bars, the bolster having on its ends the heads extending between said bars, and means rigidly securing said heads to said bars, said bolster being formed with the vertical compartments at its center and adjacent to its ends, combined with the springs seated in said compartments, and the caps mounted on said springs and affording the center and side bearing seats, said springs and caps being arranged to receive the car-body and its load about equally; substantially as set forth.

2. In a car-truck, the side frames having upper and lower bars, combined with the integral cast bolster having on its ends the heads adapt-ed to said bars and affording columnposts through which the column-bolts pass, said posts having on their upper and lower ends the gibs or flanges extending on opposite sides of said bars; substantially as set forth.

3. In a car-truck, the side frames having upper and lower bars, combined with the integral cast bolster having on its ends the heads extending between said bars and secured thereto, said heads comprising the columnposts connected together by webs and adapted to receive the column-bolts; substantially as set forth.

1. In acar-truck, the side frames having upper and lower bars, combined with the integral cast bolster having on its ends the heads extending between said bars and secured thereto, said heads comprising the columnposts connected together by the inner and outer webs which are themselves connected together by the transverse integral sections; substantially as set forth.

5. In a car-truck, the side frames having-upper and lower bars, combined with the bolster having on its ends the heads extending between said bars and secured thereto, the springs seated within said bolster at its center and adjacent to its end portions, and the caps on said springs and affording the center and side bearing seats, said heads and the sidebearing caps being recessed to permit inspection of the springs below said caps from the outelr side of the truck; substantially as set fort 1.

6. In a car-truck, the bolster extending between and secured to the side frames, said bolster being an integral casting having compartments formed therein at its center and adjacent to the side frames of the truck, springs within said compartments, and caps on said springs and affording the center and side bearing seats, said caps having freedom for lateral play endwise of the bolster and said springs being adapted to receive the load about equally; substantially as set forth.

7 In a car-truck, the integral cast bolster having the rectangular compartments formed therein at its center and adjacent to its ends, the sets of rectangularly -arranged coiled springs seated in said compartments, and the rectangular caps mounted on said springs and affording the center and side bearing seats, said springs and caps being arranged to receive the car-body and its load about equally; substantially as set forth.
