Specification of Letters Patent.

Patented June 4,1907.

Application filed September 7, 1906. Serial No. 333,675`

To all whom, it may concern:

Be it' known that I, WILSON E. SYMoNs, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented a'i'new and useful Car- 'l `ruck, of which the following is a specification.

This invention relates to cartrucks of that general type disclosed in my former patents N 0s. 649,183, dated May s, 1900, and 700,992, dated May 2,7, 1902. The -truck possesses, in common with the former constructions, extraordinary .strength and durability, notwithstanding its extreme simplicity of conf struction and light weight.

The object of the present. invention is to produce a truck possessing all of the desirable characteristics of my former constructions, but .having greater elasticity in the connection between the side frames, so that torsional and other strains due to undulating or imperfect track Awill be absorbed by the objects, and others subordinate thereto, the` connection without injury to either the side or cross memberso the truck frame.

A further object of the invention is to veliminate from the truck the r'igid cast steel transom heretofore extended between and keyed to the side frames, and to substitute in `lieu thereof one or more comparatively' elastic cross members and two metal end members extended through the side members and interlocked with the side and cross members, the side, cross and end members being combined and related in a manner to facilitate the assembling of the truck structure or the disorganization thereof for purposes of repair.

A further object is to so construct the end members that they will serve not'onlyvas retaining` devices for the cross members, but also as combined supports for the brakebeam-hangers and seats for the bolster supporting springs. i

A further object of the invention is to combine with theel'astic connection between the bottom portions of the side members, a hold'- in means engaging the upper portions of the si e members to prevent spreading thereof and serving to assist in guiding the bolster 1n its vertical movement.

To the accomplishmentof the foregoing present embodiment of the invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and succinctly deined in the appended claims.

Fig. 8 is an outer end view of one of the end members. Fig. 9 is a side elevation thereof. Fig. 10 is a top planview of the end member. Fig.` 11 is a sectional View of the bolster. Fig. 12 is an inverted plan view of one end of the bolster. Fig. 13 is a plan view of one of the cross members. f Fig. 14'is a side elevation of the middle portion of one of the side members, showing a modified arrangement of the cross and end members.

Fi 15 is a section of the arrangement shown in ig. 14. Fig. 16 is a sectional view of the same subject-matter taken on a line at right angles to the line in Fig. 15, and Fig. 17 is a getail view of the end portion of a cross mem- Each part is indicated by the same reference character in all of the views.

The side frames 1 are generally similar to those shown in my Patent No. 700,992, being steel castings each having a central opening 2, and open jaws 3 atits opposite ends, the latter being adapted for the reception of the journal boxes 4 ofthe axles 5, supportedby the truck wheels 6 in the usual manner. The boxes 4 areA retained in the 'aws 3 by keys 7 having semicircular outer aces and passed vertically through the outer ends of the upper and lower members of the side frame between which the jaws are defined.

A Each side frame comprises an upper member or arch bar 8, a lowermember or binder 9, central struts 10, and end struts 11, which elements, being in an integral structure, combine to form a strong, rigid, light-weight side member of comparatively inexpensive construction. The side frames differ somewhat IOC indicated in Fig. 7.

from those shownin the patent above iden- 1 and through the central openings thereinv and comprising horizontal flanges 14 the ends of which rest upon the widened portions l2 of l the binders 9 and vertical flanges 15 opposed to the inner faces of the central struts 10`and extended, like the flanges 14, to the outer edges of the side members. An interlocked connection between the cross members 13 and the side members 1 is effected by dowels 16 preferably cast integral with the bottom members of the side frames and engaged in openings in the horizontal flanges 14' of the cross members, as shown in Figs. 5, 6 and 7. v It will be noted, by reference to Figs. 3 and 7, that that portion of the side-member constituting the bottom or sill of the opening 22 is not only widened, but is formed at the inner side of the member with a material extension 9a forming an extended bearing or support for the cross members 13 which, in addition to being interloclred with the side membersv through the medium of the dowels, may be additionally secured, if desired, by riveting the flanges 14 of 'the cross members to the extensions 9a of the side membersas lt should be understood, however, that while certain conditions of service make it desirable to utilize the extensions 9*l and to rivet these extensions to the cross members, both of these features may be omitted under someconditions and under others the extensions may be emn ployed but the rivets omitted.

rlhe engagement of the cross members with the dowels 16 and the Aabutment of the end" portions of the flanges 15 with the struts 10 insures a rigid connection of theside and cross members, but facilitates their disconnection by the simple act of lifting the crossl V cross members 13 constitute in elect a sand board or spring plank, since they perform the functions of the lower portion of the transom eliminated from this construction. These cross members or angle bars 13 are suflciently elastic to absorb the torsional strains due to undulating track without danger of injury to any portion of the truck structu re .i In order to secure the greatest possible elasticity consistent with strength and durability, said bars are constructed of wrought iron or'mild steel, preferably the latter, and it will of course be understood that the exact form and dimensions of these bars may be varied in acsedili cordancewith the type and capacity the truck in which this particular feature of the invention is incorporated.

Extended through the central opening 2 of each side member 1 is an end member 17 constructed as shown in Figs. 6, 7, 8, 9 and 10, and formed in va single casting, preferably of steel or malleable iron. These end members assist in the retention of the cross members 13 and constitute combined spring seats and brake-beam-hanger supports, since they are constructed, in a manner to be described, to be interlocked with the side and cross mem-` bers, and are provided with seats for the bolster supporting springs and with lugs or ears for the attachment of the brake beam hangers.

As best shown in Figs. 8 to -10 inclusive,

each end member 17 comprises side walls 18 of considerably greater width than the. side member, but having their outer edges coincident with the outer edges of the side meinbers, so that the major portions of said walls extend inwardly from they side members, as shown in Fig. 7. The walls 18 are connected by a top member 19, which is disposed below the upper member of the side frame, being substantially the same width as said .member and provided at its -front edge with an abutment flange 20 abutted against the inner face of the side member, as shown in Fig. 7, and extended upon the side walls 18, as shown in Fig. 8. The bottoms of the side walls 18 are widened, as best shown in Fig. 9, and are connected by vertical walls 21, 22 and 23 of inconsiderable height and by bottom walls 24 and 25, which latter rest upon the hori' zontal flanges 14 of the cross members. The wall 25 extends between the vertical walls 22 and 23 and is preferably cut out for lightness,

as shown in Fig. 10, while the bottom wall 24 is in the form of a narrow plate disposed lon- 21 and 22 and provided With openings for the. reception of the dowelsl, 'see Figs. 6 and`7. The lower portion of the end member extends beyond the outer side of the, widened portion 12 of the side member, see Fig. 7, and the bottom 26 of this extended portion is dropped below the plane of the bottom Walls 24 and 25 to bring it in abutting relation with theend faces of the cross members 13. It

gitudinally of the truck-midway of' the walls ITO will thus be seen that a rigid interlocked rey dowels thereof, while the end member extends through lthe side member, engages the `central struts and dowelsthereof, and imoses its weight upon the cross members and is disposed in abutting relation with the outer ends of said members, which assemblage and relation of parts efiectually resists the strains in all directions.

` members 17 is secured by providing horizontal projections or dowels 16a extending from the opposite side walls of the end members, see Fig. 9, and arranged to engage notches 16b formed in the upper edges of the vertical flanges 1 5 of the cross members, see Figs. 5 and 13, these notches being cut out of line with the openings which receive 'the dowels 16 to minimize the liability of a transverse con-v necting fracture. It will also be noted, by reference to Figs. 6 and 7, that while the lower portion of each end member is widened transversely of the truck, such portion is somewhat narrowed longitudinally of the truck in order to permit such portion to fit between the vertical fianges 15.0f the cross members. Attention is further directed to the fact that the lower ends of the openings 2 in the side members 1 are slightl narrower than the upper ends thereof for t e urpose of bringing the vertical flanges of t e cross members in proper relation to the bolster 27, which must be of such Width as to permit its ends to pass between the side walls of the end member, as will be presently described.

As an additional security, the inner faces of the central struts 10 of each side member are formed, either during the casting of the member or subsequently, with notches or key seatsV 28 into which are extended from the side walls of the end member a pair. of lugs 29 preferably having their outer faces inclined, as shown, and formed for the sake of lightness by casting a rectangular flange or ribV on each side of the end member. The key seats 28 are of sufficient length to permit the end member to b e passed into the side member at a suicient height to clear the dowels 16 and to be then dropped down'into engagement with the dowels and retained in such position by the insertion of keys 30 through the key seats 28 above the lugs 29 and through key openings 31 the side portions of the abutment flange 20 of the end member, see Figs. 3, 6 and 8. The ke, s 30 may be of any suitable form or materia but are preferably headed, as indicated at 32, see Fig, 3, to engage the outer edge of the adjacent strut, and are provided at their inner ends with removable pins 33 passed through the key adjacent to the inner face of the flange 20.

. As heretofore stated, each member 17, in addition to its function as a retainer for the cross members, also affords a seat for the bolster supporting springs. To this end the end casting is 'formed with a horizontal wall or spring seat 34 extending between the side walls 18 and also between the short vertical walls 21 and 22 adjacent to the-upper edges of the latter, as shown in Fig. 7. The seat 34 is thus elevated somewhat above the bot` tom of the end member, and its upper sur- 9 and 10.

face is formed to receive four sets of bolster supporting springs 35. The seat 34 is also provided with sand holes 36, as usual. Since .the weight of the bolster and the car structure supported thereby is sustained by the spring seats 34, the latter are preferably stiffened by vertical walls or webs 37 disposed below the seat and extendin between the walls 21 and 22 in spaced re ation to each other and to the side walls 18, and formed integral with the walls 21 and 22 and with the spring seat 34 and the bottom wall 24 of the end casting.

The bolster 27, see Figs. 2 and 7, is of sufficient length to be extended through the end members, so as to dispose the spring seats 38 of the bolster above the seats 34 of the end members, it being understood that the seats 38 rest upon the springs 35 and are formed by diaphragms cast as integral parts of the bolster structurev and extended between the side Walls thereof in a plane above the lower edges of said walls, the construction being similar to that disclosed in my former patent. The bolster is also provided with the usual thrust flanges 39, which, however, instead of being opposed to the side member of the truck in the ordinary manner, are, opposed to the abutment flanges 20 of the adjacent end members, as shown in Fig. 7. By reason of this relation' the end thrust of the bolster is sustained by the end mem-` bers and it follows as the inverse of this proposition that the thrust flanges 39 of the bolster furnish additional resistance to any IOO tendency of the end members to move inwardly. It is also intended that the bolster shall constitute means for resisting any tendency of the end members or side frames to move outwardly. To this end headed keys 40 are passedhorizontally through the outer ends of the bolster just beyond the outer ed es of the end and side members, as shown inigs. 1, 2, and 7, and retained by pins 41. It will be obvious that these keys 4() not only constitute outer guides orathrust members for the bolster, but that they alsol serve to hold the upper portions of the side frames and end members in proper position, since they resist any tendency of the upper portions of the side and end members to spread.

We have now seen that the end members 17 assist in retaining the cross members 13 and that they constitute seats for the bolster supporting springs 35. They also serve, as heretofore stated, as supports for the hangers 41u of the brake beams 42, each end member being formed with lugs or ears/43 extending outwardly .from the side walls thereof at points between the side frames for the attachment of the hangers 41, see Figs. 1, 8,

In Figs. 14 to 16 I have illustrated., a somewhat modified construction. In this form of the invention the end members 17, in-

stead of being in the form of open frames inclosingthe ends of the bolster, are in the form of comparatively lightspring-seat castings or pressed steel forms which rest upon the cross members and engage the dowels, as

seen that by this arrangement vertical movement of the cross members in the side frames is prevented by the walls of the seats or cutout portions of the latter, while the interposition of the end members between the cross members prevent the latter from moving inwardly. Under some conditions the side walls ot' the spring seat castings or end members 17aL are provided withextensions 17b secured to the vertical iianges 15 ol the cross members in any suitable manner7 as for instance by rivets 17, see Fig. 16.

It is thought that from the foregoing, the novel vconstruction and arrangement of the elements of my truck will be clearly comprehended, but while the illustrated embodiment of the invention is thought Aat this time to be preferable, I desire to reserve the right to make such changes, modifications, and variations oi the illustrated structure as may come fairly within the scope of the protection prayed, and to construct the various parts of such materials and to effect their manufacture in such manner as may be deemed desirable.
