To all "107mm t may concern.'

Be it known that I, VILLIAM K. AUCHIN- oLoss, residing at 569 West End avenue, New York, N. Y., and being a citizen of the United States, have invented certain new and useful Improvements in Tank-Anchors for Tank-Cars, of which the following is a full clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings; which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details 'of construction shown and described, as it is obvious that various modifications thereof. within the scope. of the claims will occur to persons skilled in the art..

In said drawings:

Figure 1 is a transverse sectional view taken through a fragment of the bottom sheet of' the tank of a tank car and transversely through the center sills,v showing in end elevation the anchoring means forming the subject matter of this application;

Fig. 2 is a fragmentary side elevational view showing at the upper part in section a fragment of the bottom sheet of a tank, and at the the upper portion ofthe center sill with the anchoring means shown in elevation and partly broken away for purposes of illustration.

`The object of the invention is to secure in a tank car a low center of gravity, to provide tank anchoring means permanently secured,respectively,'to the tank and to the center sill, which anchoring means are so disposed with relation to each other that the assembly of the parts is conveniently arranged so as to permit driving machine driven rivets to secure the anchorto the sills or underframe the anchor is connected, and to the tank.

Referring to the parts, 2)*3 indicate the center sills of an ordinary tank car underf'rame, which sills are ordinarily spaced a convenient distance apart and in the present instance are connected by means of a transversely disposed top sill cover plate 4, which cover plate is preferably of a single sheet entire length of the anchor and is secured to the top flanges ofthe sills by rivets 5, which "rivets may 'are adapted to secure the bottom of the view a fragment of member of the car with which" be machine driven before the tank is placed 1n position, due to the space surrounding the rivets, which will permit application of the rivet heading means commonly used.

he cover plate 4 or equivalent transversely extending member connecting the sills has angular extensions (3-6 which, as will be noted, are beyond the top flanges 7 of the center sills and are spaced some distance therefrom.

The flanges 6 are perforated to receive the connecting rivets hereinafter referred to,

Secured to the bottom sheet 8 of the tank is a pair of tank anchoring members which tanks to the underframe and. these members consist each of a sheet of metal 9 which is formed at its middle portion l0 of a. channel shape, as best shown in Fig. 1, and terminates in flanges 11 and 12, which flanges are angularly disposed withrelation to each other, the flanges 11 comprising an upwardly curved portion which extends from the middle channel portion. This upwardly curved portion is of a curvature corresponding to the contour of the bottom sheet 8 of the tankto which it is permanently secured by means of the inachine driven rivets 13, and it is to be noted that the rivets 13 should be driven by chinery because theyare subjected to 'great stresses in bufling and pulling, which stresses would, under service conditions, tend to rupture an imperfect lconnection of the flanges 11 with the bottom sheet of the tank,

An added advantage in a machine driven rivet at this point is that such rivets can be driven with sufficient force to obviate the necessity forcalking, something which is quite important in tanks vof railway tank cars adapted to carry gasolene and other hydrocarbon fluids.

Intermediate the channel portion 10 of the anchor and the downwardly and outwardly extending flanges thereof, is a shouldered portion 14, which shoulder is of importance in that it provides a seat for the anchor, when the -parts are in assembled relation.

ln practice, the parts are assembled as follows: first, the cover plate 4. or ccuimlent member, is connected by machine driven rivets to the top flanges 7 of the. center sills, with the flanges 6 depending downwardly and outwardly as shown, the anchor inem. bers 9 are secured to the bottom sheet 8 of the tank by machine driven rivets, as indiafter which the rivets l5 may be drivenby y suitable rivet driving machine, and it is to be noted thatrwhile the space between the top cover plate 4 and the bottom of the tank isonly about l in-. in an SOOO-gallon tank,

all of the rivets, due tothe disposition of the flanges indicated, may be driven by machinery and when it is desired to remove the tank from the underfram'e, as for purposes of repair, the rivets may be cut without def struction of any part, except the rivets themselves, the tank removed, repaired. and replaced as before noted. v

What I claim is: I 1. In an anchor for the tank of a railway tank-car, spaced center sills having upper flanges, a cover-plate connected with said flanges and having lateral extensions projecting outwardly and downwardly therefrom, a tank and anchoring means therefor secured to the tank and lapping said cover plate extensions.

2. In an anchor for the tank of a railway tank-car, spaced center sills havinr. upper flanges, a cover-plate connected with said flanges and having lateral extensions projecting outwardly and downwardly therefrom, and anchoring means for a tank lapping the said outward and downward extensions, riveted thereto and also extending tank.

8. In an anchor for the tank of a railway tank-car, spaced center sills having upper flanges, a member spanningsaid sills and having yextensions projecting below the top plane of said sills, a tank and anchoring means for 'the tank secured thereto and lapping said extensions.

4. In an anchor for the tank of a railway tank-car, spaced center sills, a transversely extending member connecting said sills and to each other, one of said flanges extending upwardly and outwardly and one of sai flanges' extending outwardly from said middle portion and thence downwardly and both flanges being perforated.

6. As an article of manufacture, a tank anchor adapted to secure the tanks of railway tank cars to a car underframe member and consisting of a shouldered middle portion adaptedto rest upon such underframe member and terminating in flanges angularly disposed with relation to each other, One. of said flanges being ada ted to form a seat for the tank andone o said flanges 'being adapted to extend below, said shouldered portion for connectionwith said member.

In witness. whereof .I have hereunto set my hand in the presence of two witnesses. upwardly and outwardly to fit the shell of a l f WILLIAM K.. AUCHINCLOSS.
