Application led January 13,1894.- Serial No. 496,720- (No model.)

` is a full, clear, and exact description, refervzo ence being had to the accompanying drawings, forming part of this specification.

This invention relates to a device for over coming or largely reducing theconcussion of cars, and carriages incident to the passage'vof the wheels over rough or uneven tracks, or obstructions thereon, which vertical movement, and consequent concussion is thus reduced by means of supplemental laterally projected bearings to those of the axles, which in combination with a bell-crank lever lthat connects said laterally projected bearings with the truck frame above and a coupling beam and tube tension coupling that connect the forward and rear running gear, largely transfers the now injurious vertical lconcussion of the running` gears, into an innocuous lateral spring vibration; and the invention consists in features of novelty hereinafter fullydescribed and pointed out inthe claims. Figure I is a top view of the running gears of a motor or other railway truck, with my anti-concussion spring bearing attachment. Fig. II is an end View of the same, and Fig. III is a side view of the same part in detail section and shows the tubular tie tension jointed main coupling beam of the running gears, and their lateral supplemental spring bearings, connected by the bell-crank with the surmounting truck. x

Referring to the drawings:-1 represents the rail track. 2 are the car truck wheels, that run thereon. 3 are the axles on which said wheels are fast mounted and which axles have their bearings in the brasses within the pedestals of the spring bearer boxes 4, in which the vertical springs 5 are housed and play.

6 represents the tubular bases of the compound pedestal angle frames 7, which compound or double pedestal frames are cast integralA and carry the spring bearer boxes 4. The upper corners of said compound pedestal frames have projecting circular bosses 8 cast thereon, to strengthen them at the points levers most subject to fracture, and through those of said bosses located at the inner corners of said compound pedestal frames, and through said frames are bolt holes 9, which correspond with the journal bearer holes, which in consequence are alike numbered 9 through the elbows 10 of each of the four bell-cranklevers 11, and through the inner bosses 8,'inside said inner upper corners of thecompound pedestal frames, which inner bosses serve for side bearings to` the elbows of said bell-crank levers.

y 82 are the lugs thatyproject inwardly from the outer upper corners of said compound pedestal frames, and which lugs serve as vertical guides to the bell-crank levers as they vibrate vertically on the spring cushions 16, and during the transposition in a measure ofthe obnoxious vertical concussion into the innocuous horizontal vibration, that is aided by the inliuence of the horizontal springs 33 and 35 'on the pendent arms of lthe bell-crank levers. 12 are the journal boltsthat occupy their perforate bearerseats 9,-and constitute the journals on which said bell-crank levers work, and which journal bearings of said bell-crank leversare each respectively about one quarter way concentrically removed toward the midway point between the forward and rear axle bearings, and thus tov arelative extent is re' duced the obnoxious concussion from the respective rise and fall ofthe surmounting car;

Aattachment ends 13 of the bell-crank levers,

through the perforate rubber spring cushion blocks 16 and the washers 17, where` they are securely fastened by the screw nuts 18. The 95 upper ends of said guide bolts pass through one of the perforate ends of the upper ball housing plates 19, and through their bolt holes20, in said truck or car sills 14, and their upper screw tips are there secured by the roo screw nuts 21, which tightly draw the swell shoulder bars or nuts 22 that integrally pro-` ject from said guide bolts against said upper ball housing plates 19'. The reverse perforate Y end of said plates are secured to said sills by the bolts 23 that pass through said sills, and said plates and their screw tips are secured by the screw nuts 24. 25 represent the lower ball bearer seats that surmount the terminal ends of said bell-crank levers. 27 are cup ball housings that are bedded in said seats in which the bearer balls 28 are housed and Work, correspondingly in their movements in their cup housings 29 in the upper ball housing plates 19. As said bellerank lever rises and falls, the said bearer balls 28 work within their housing cups and steady the movement of said bell-crank levers, in corrective response to the concussion of the wheels in their passage over slight obstructions or inequalities on the tracks, said vertical movement of the long, nearly horizontal arms 30 of said bellbrank levers, on their guide bolts l5, being readjusted by said perforate V rubber spring blocks 16 to`bring said arms of the bell-crank lever back to their normal position.

31 represents the short nearly vertical arms of the bell-crank levers, the lower ends of which are connected to spring valve reels 32, that run within the aforesaid tubular bases 6 of the compound pedestal angle frames 7. 33 are spiral springs that lie and work horizontally within said tube bases between the outer ends of said reels and the disk stopper ends 34 of said tube bases. 35 represents volute springs that lie and work within said tubular bases 6 between the inner ends of said reels 32 and the adjacent ends of the tubular tension beams 36.

The said tubular tie beams constitute another element of the invention. Their respective tension ends 37 are inserted by machine pressure within the correspondingr tubeholder ends 38 of the respectively projecting ends of the aforesaid tube bases 6 of the compound pedestal 7. The said tubular tie beams have integral disk closures 39 at their ends, which greatly strengthen said ends of the tie tubes to resist fracture when being inserted by extreme machine pressure Within said tube holder ends 38 of said tube bases 6 of the compound pedestal frames, so as to maintain a reliable tension hold, without being pierced by bolt holes and tie bolts that constitute points of Weak ness, and starting points for fracture under adverse strains on said tubular ties. Itis therefore claimed that said tubular tension ties 36, within their tubular tension holds 38, which holds are reinforced by the peripheral beading 38', add greatly to the strength and to the stiffness ofthe combination and its tie, with the same amount of metal as used in the usual solid tie beams, but more advantageously disposed to brace itself and to brace its tie connection.

40 represents cross spring bearer bars that integrally' connect the respective sides of the compound pedestal frames at their outer ends at somewhat lower levels than that reached by the lowest dip of the long arm 30 of the bell-crank lever, and 41 are the rubber or other suitable spring cushions that are seated on said cross connecting bars, and in cases of extreme concussione said spring cushions arrest the too extreme depression of the long arms 3U of the bell-crank lever, under the weight of the loaded truck or car.

42 represents the lower and 42 the upper clutches of the grip holder clamps that embrace around said tubular tie beams 36.

43 are the base bars and 44 the surmounting bars of the angle motor carrier frame 49, the conjoint double perforate ends 45 of which bars are secured by the screw bolts 46 and nuts 47 to the perforate duplicate flanges 48 ou each side of said grip holders through which they pass.

50 represents wing fianges that surmount the grip holders 42 and 42', and which wings have raised square edged shoulder blades 5l that firmly brace against the upper bars 44 of said motor carrier frame 4). 54 are the central vertical tie bolts which are seated in the perforate centers of said respective base and upper bars of the motor carrier frame 44 and are there secured by the screw nuts 56.

57 represents the life guards that are secured together at theirangle fronts by rivets 58 to the perforate overlap tie plate 59 and at their rear ends are secured by rivets 60 to the perforate angle bent attachment bars 61, that are themselves secured by rivets or bolts 62 to the curved end oars 63 of the running gear frame.

64 represents upper tie bars the screw attachment ends 65 of which pass through the perforate corresponding bail shaped coupling inner ends 66 at the upper angle corners of the compound pedestal frames 7, where said tie bars are stayed by the shoulder nuts 67 and are secured in their seats by the screw nuts 68.

The general combination and functions of the invention have been nearly sutciently described during the introductory description of its several parts, but it may be further stated that by means of the laterally diverted bearings of the journal bolts 12 of the supporting bell-crank levers toward the midway centers in the running gears from that of the axle bearings to any desired proportionate distance from said axle bearings, (it being shown see Fig. III located at about one fourth of the distance,) just in the same relative proportion will the elevation of said bearings of said bell-crank lever be reduced as compared to that ot' the axle and wheel, when the latterruns over any impediment on the track; but I do not confine myself to said gain of one fourth as it affects concussion in the respective positions of the axle and supporting nell-crank lever bearings, for it is evident that the bearings of said bell-crank lever for either passenger cars or trucks that carry easily destructible freight may be placed as near as desired to the common center of the running gears, and to the same relative degree still further reduce the con- ICO IZO

35 in their elastic induence on the'bell-crank lever very materially amelioratesthe concussion.
