' 1929. Serial This application is a division of a certain pending application heretofore filedby me, entitled Safety railway trucks, filed Apri 11, 1928, Serial Number 269,133. r

V This application relates to the following United States patents which have been granted me: railway roadbed and track construction, issued" December 11, 1928, No. 1,694,811, and to my'patent issued December 28, 1926, No.- 1,612,271. This application alsorelates to the following applications filed by me and now pending-in the United States Patent-Office :a 'switchingdevice, Se. rial Number 184,685, filed April '18, 1927; a railway switch, SerialNumber 184,687, filed April 18, 1927; railway roadbed' and track construction; Serial Number 184,686, filed April 18, 1927 and a railway crossover, Serial Number 2 l0,164, filed December 15,1927.

The primary object of'my invention consists in the prevention ofderailment of railway vehicles, especially when cars are moving athigh speeds, and I attain this object by the employment of safety wheels secure- .ly attached to thetrucks of such cars and operating on the under surface of a special tread. 7

Referring to the drawings:

. Fi ure 1 shows m T invention bein utilized n V p 3 7 .upon one or the common types of' freigh-ttrucks. in this instance the, truck is provided withthe common-and well knownmembers constituting a part thereof, such as wheels 1- which rest upon track rails '10, the

' o urnal boxes 6 side frame 3 bolster s r'i-n "s 15', side frame truss 5,'and pedestal tie bar 4. In this instance, the tie bar 4: is provided with a'downwardly projecting integrally formed member or bracket 7. Viewed from the side, the bracket is seen to be. atria-ngular or V- shaped member provided with a substantial reinforcing rib 17. Added strength is given the bracket 7 by means of the brace 22 which extends between: thebracket 7 and a. cross beam 23 of the truck. Fastening means for securing brace 22 to the bracket and cross beam are indicated by the numeralQ l, and thesemeans may be bolts, rive-ts, set screws or any other means found suitable for the purpose. if i The bracket 7 is intended-for carrying a guard or safetywheehsuch as the wheel 2,

Similar reference numerals indicatesimie which jtravelsalong an; under surfacetread.

It-is, of course, necessary to provide a special tread for guard-wheel 2, which in this case forms a partof the r-ails 10. RailshlO have 1 the usual web 12 and base flanges, the outer- V base flange 11' being widened sufficiently to provide-a tread for whe'el2 on'its, or the outer portion of its, under surface. To allow'wheel '2 to clear ties 14E, rail 10is elevated on sleepers such as the I-beams 13. It will be seen that the vertical alignment of the inner sideof bracket 7 is such that itclears the flange 11.

Fig. 7 is an enlarged cross section of a The bottom or point of the bracket is pro- [vided with a. bore or socket which is occupied by the shaft or spindle 18. Shaft 18 has a shoulder 25 which bears against the inner face described.

of the bracket. A nut 19 threaded upon the threaded end 29 of the shaft holds it in position. p

Two forms'of safety wheels arehcre shown. That shown in Figure 3 being formed of two complementary members 2A held together by the bolts QT'eXtending through theweb 2B of the wheel 2. shaft 18, and balls 36 are provided within the hub thereof to secure an anti-friction bearwheel to be taken from snaft 18 when such shaft is. free of its supporting bracket or frame.

7 It may not always be advantageous to pro vide brackets upon the tie bars 4, especially in those instanceswhe'rein the trucks are provided with equalizing bars. In'such an event a bracket 9 shown in Figures 8 and 9 may be provided. purposes similar to bracket 7 save that it is attachable or detachable. It will. be seen that this type of bracket readily lends itself to attachment to trucks without the necessity of making any radical changes in such trucks.

Figure 5 and its derivatives show modifications of my invention to enable it to be used in connection with trucks provided with equalizing bars, to the extent that the bracket or its equivalent, a frame or arms, performs the same function as the bracket-7. In this instance the truck has the usual elements going into its construction, such as wheels 1, journal boxes 6, equalizing bars 33, 33A, side frame 3, truss 5, pedestal tie'bar 4: and equalizer springs 16, all .well known in the art. The equalizing bars are in spaced pairs 33 and 33A respectively. Extending downwardly from each equalizing bar j are two arms, 8 and 8A. for'the respective equalizing; bars, which join-and form a'v shaped structure. Correspondingly directedarms on the equalizing bars are spaced apart and so held by spacing blocks 85 which are positioned midway their length, such blocks being held in position by the bolts 26. At the base or point of the arms is another spacingblock 34 through which the shaft 18 extends. The shaft 18 is secured to the arms and block 34: in the manner heretofore described, and carries rasafety'wheel as previously described.-

The wheel 2 is mounted on.

This bracket is to all intents and I Having described the several features of my invention, what I'claim as novel is 1. In combination'wit-h a railway truck, a downwardlydirected frame composed of inclined arms to provide a V shaped bracket, said arms beingin like directed pairs spaced apart, spacing blocks extending between the midportion of each pair of arms, a spacing block at the point of said bracket, said bracket and the last mentioned spacing block having a corresponding bore, a spindle provided with a shoulder intermediate its ends, said spindle said arms being in like directed pairs spaced apart, spacin blocks extending between the midportion of each'pair'of arms, a'spacing block at the baseof said arms, said bracket and the last mentioned spacing block having acorresponding bore, a spindle seated in said bore, and agsa-fety wheel, designed for travel on the undersurface of a suitable tread, jourv naled upon said spindle.

3. The combination with a railway truck,

.of a downwardly directed frame, said frame being'composed of two V-shaped members each provided with correspondingly inclined arms and being so arrangedfthat the arms of one memberare spaced from the like arms of the other, fastening members extending between corresponding arms and between the bases of the two members, a spindlemounted to the bases of said members, and a safety wheel, designed for travel on a guard rail, journaled on said spindle;
