and 2, or may comprise a separate casting held in position by bolts or rivets passing tliroiigli sail lugs and through the center sills, as may be desired. The parts of the car may be assembled with the anchor attached to the tank, after which the tank may be placed in position and the wedges drawn together by pressure 01 the adjusting nut 13. The preferred manner of assembling the parts to rivet the bolster-center tiller 5 with its integral lugs (3 in position between the center sills, support the upper wedge 10 in position by a pin pass ng through the orifice 15 of sullicient length to span the gap between the center sills. thereby supporting the wedge 10 in position with the bolt 12 held in position in the upper wedge, after which the tank may be placed in position, the pin referred to withdrawn from the oril'fce 15, whereupon the wedge 10 will fall by gravity to a position between the lugs (5 and the anchor T,'a1'ter which the wedge ll may be placed in position on the bolt. When this is done the nut 11 is screwed on to the lower end of the bolt, thereby bearing against the lower face 01 the lower wedge 11, and cansing tlie'licad of the bolt to bear against the upper face of the upper wedge ii), in consequence of which, as said nut 13 advances on the bolt, the wedges 10 and 11 will be drawn together, thereby filling the gap 16 between the lugs t3 and anchor 7, It is evident that the wedges on each side of the longitudinal center ol the underframc may be separately adjusted to compensate for any irregularity of spacing of the lugs 6 and next adjacent faces of the anchor 7. The serra' tions 17 in the opposing faces of the lugs 6 and the wedges 1t) and 11 are oppositely disposed; that is, the serrations at the upper portion of the face of the lug (5 open'downwardly and the serrations at the lower portion of the lugs 6 open upwardlv, while the serrations in the wedges l0 and 11 are oppositely dis 'iosed.

It is evident that in a structure subjected to the vibratory stresses incident to operation of a tank car that the wedge 10 will settle or become automatically positioned in a lower plane during the operation of the car, at which time the upwardly open ser rations on the lower face of the lug 6 will hold the lower wedge 11 in position, so that the upper wedge 10 will automatically adjust itself during shifting longitudinally of the tank on its :iiidcrl'rame. \Vhile there may l i an advantage in placing the wedges near both ends of the underfranic, it is evident that but one set of said wedges is necessary, as the operation of the upper wedge is automatic and will readily compensate for any increase in distance between the anchor- 7 and its ontiguous lug I ly using the wedges in connection with the anchor for the tank, it is obvious that the tank may be more firmly locked in position against movement iongitudinally of its supporting under-frame. It is well known that tanks of tank cars are heavy bodies which are ordinarilylifted by means of power cranes, and extreme care must be taken in placing the tanks in position under normal conditions, in addition to which some clearance between the anchor 7 and the stop lugs is required to facilitate placement of the tank, which clearance, even though small, sometimes permits independent movement of the tank on the underframe.

When the wedges 10 and 11, or a single wedge 10 is used, as before described, it is evidentthat the tank may he placed in position with the wedge 10 in position, after which the wedge 10 will automatically a djiist itself so as to fill the gap 16. Another advantage in the use of the two wedges is that the tank is more securely held in position above the bolsters, so that rocking of the tank on its underframe is prevented.

'hile the wedges 10 and 11 are held in position in operation the tank will be held by friction of such wedges against the face i), so as to prevent separation of the tank and under-frame under normal conditions, though it is obvious that there will be no positive interlocking of the wedges with the face 9 of the anchor which will prevent separation in the event of a wreck tipping the car oil the track, in which latter case such separation is desirable to facilitate replacement.

What I claim is:

1. In a tank anchor for tank cars, the combination of a fixed abutment and Ta juxtaposed vertically mo able anchor, said abutment having a face inclined in two directions, and a Vertically movable interposed wedge.
