The parts 3, Il, and 'naiethe/ chief' ele# .ments `of the nnderiiianie' above mentioned'.

The cradles of thennderi'anie are pef'eiably so designed `that tlie bottom, ofjth'e 90 tank is several 'inches 'alioife'tlie top,"4v, f the underfraine'. f f

I My novel anel10rage,` Aidis placed, and acts, between the-top; il, *ofthef silland 'the bottom, 6', of the taiikyfneai".nefdflthe'bol- 95 sters, 3Q i .f y

The sill, 4, is usuallyl coinposedfof two ehannel-beams,r` 4,7; vconnected byfcover plates, el, As will presently under-v stood, it is desirablegan'vd also most eenven- 100 ient to apply the anchorage toftlie'top flanges of tlieeentersill oif-girdeliA. While it is'feasible :to position it'inidway' l"on the topvof the sill, 41,11 pieferto make it in laterchorage may. occupy any desired.lorigitudi-V inal position ontlfie sill,- "4, but I lin'd V most s iininee pai'ellol lto the axis of tile--l desirable and eeetiye N ,when l `placed as one of the bolsters, 3, and Withits inner'v end i are parallel."-

complementary members, a,

- upper edge the tank. The sides, b, of the member, I),

The length of the anchorage is determined by the size of the tank and the thickness of the plates and flanges to which the complementary parts of the anchorages are riveted. The two sections of the anchorage, A, Each section comprises two and, b. The

lower member, a, is preferably an angle-bar havingl its lower flange attached by a row of rivets, c, to the plate, 4V", and top flange of beam 4". V The vertical flange of the angle bar is notched and thus provided with a series of spacedv upstanding rectangular teeth' or lugs. The upper member, b, of the anchorage, vA, is a channel or trough preferably formed of sheet metal and 'presenting edgeswhich are attached to the bottom of the tank, 6, by three rows of rivets. A single row, e, is used at the inner edge of the trough and two rows of rivets, f, are preferably used for attaching the'outer and of the trough shaped member to preferably convergedownwardly and are joined by a flat bottom portion, Z2. The bottom, b, contains a rowl -of slots, 9,. of sizes to snugly admit the corresponding teeth, d, of the member, a; which teeth eX- tend upwardly through the slots, g, as best shown in Fig. 2.-

'I prefer that the edges of the serrations or teeth, d, shall be vertical rather than inclined, butvmy invention contemplates the inclination thereof. Myinvention also contemplates the inversion of the members, a and b. The thin tank plates aiford the least vsecured fastenings for rivets, but provide the best footing for the flanges of the trough shaped members and I therefore much prefer the arrangement shown, with the fine distribution of rivets on the nidely separated lines made possible by the application of the trough-shaped member to the tank.

through the medium of, and the shifting vof l50 The parallel sections of the anxfhoragc mutually laid one another to prevent both longitudinal movement and rotation of the tank on the underframe.

When desired the tank may be lifted olf the underframe Without disturbing the fastenings.4 As the complementary members of the anchorage are engaged through the medium of vertical teeth the tank may be either lremoved, or lowered into position, without 'necessitating the disturbance ofany of the'- rivets by which the complementary members of the lanchorage are secured.

, When the car is subjected to an endwise shock, the force. is communicated to the tank the tank is prevented by, the intermeshiug. upper and lower members of the anchorage. Each tooth ofthe anchorage .takes its part of the load and communicates it directly to that part of the complementary member which it engages. In this manner the force length of the anchorage andthe latter is relieved from vertical strains which would tend to bend .the ends of the complementary parts and pull out the rivets. Under these conditions every rivet in the anchorage is -is distributed uniformly throughout the l subjected only to shearing strains and each rivet is permitted to effect its maximum resistance to the shock.

An important feature of my invention is.

that the line of engagement thus provided between the tank and underframe is 'substantially midway of the height of the anchorage and that the bending 'arms of the anchorage are thereby shortened one-half as compared with the bonding arms of those `anchorages in which the line of engagement is on the tank or on the sill. rlhis shortening of the eHective bending arm of the anchorage causes it to act reliably without bending, and hence the danger of bending the bottom plates of the tank is avoided.

A distinct advantage of the anchorage shown lies in the fact that all of the rivets are in open, easily accessible positions, an item of interest in considering the cost of the car.

- The eXtreme simplicity, 'durability and economy of my novel anchorage will be apparent to car builders and users.

Various modifications of my invention `will readily suggest themselves to one who is skilled in the art, and except as specilically pointed out in the appended claims, I do vnot limit the invention to the precise construction herein shown and described.

Having thus described my invention, l claim as new and desire to secure by Letters Patent v 1. A tank car tank anchorage comprising,

-in combination, two complementary members, having oppositely faced bases and one thereof provided with a longitudinal row of teeth and the other being formed with a longitudinal row of recesses to receive said teeth.

2. A tank car tank anchorage comprisingl a trough-shaped member containing a longitudinal row of perforations, in combination' Q tank member containing a longitudinal row of slots, inv combination with an underfrarae llt) member presenting a eoireeponding rovv of teeth in said slots.

6. A. tank car tank anchorage comprising a troughshaped member containing; a lon `itndinal rovv of oblong perforations in com ia row oi? oblong,1 teeth, in combination with aV trough-shaped bar provided with tvvo flanges containing rovvs of rivet holes and having` in its bottom a rovv of oblong slots complementary to the teeth of said angle bar.

8. ln a tank car an underframe, in combination with a tank. horizontally disposed thereon, one anchorage member applied to said nmlerirame, a second member applied to the bottom of said tank, one of said mem.- bei's hating a. row of teeth and the other a row of perforations therefor, and said inemaaeniaa bers being intermeshed in a horizontal plane intermediate said tank and underframe.

9. A tank car tank anci wage, comprising a bar member, having an ed e formed With a plurality of teeth, 1n com mation with a parallel member formed with a plurality of slots to receive said teeth.

l0. A tank car tank anchorage comprising a membei` having a portion secured to the car tank, and a portion spaced therefrom, said spaced portion having a plurality of recesses, in combination With a complementary member having teeth entering said recesses.

11. A tank car tank anchorage comprising a rolled metallic shape having a portion secured to the'car tank, and a portlon spaced therefrom, said spaced portion being formed With recesses, in combination with a rolled shape having a plurality of teeth entering the recesses in said member secured to the car tank.

ln testimony `vvhereof, l have hereunto set my hand this 14th day-of March 1916.
