IMPROVEMENT IN RANGERS.

The Schedule referred to in these Letten Patent and making part: of the same.

To whom it may concern:

Our said/improvement relates and has special ret`-,

erence to the use of a metallic core, core-bar, or mandrel, within the mould at the time of castingI the hanger, pedestal, plumber-block, or device of like character, said core-bar or mandrel, when means of vertical adjustment are not desired, having beenA previously tted with a fchill and nut, and when suoliv means of adjustment are desired, with the necessary nuts or female screws, for the reception of the pintles orgadjustiiig-screws, which forni the external oi' concave portion of the ball-:uid-socket joint or bearing common to all such devices.

We are aware ofthe fact that hangers, and devices ot' like character, have heretofore been constructed, involving the ball-and-socket principle, but they have, prior to our invention, been iirst cast, and then bored and chased or tapped, by a laborious and expensive process, involving the use of costly machinery, provided specially for the purpose. By our improved method ot' construct-ion, we claim to obtain an accurate and perfect mechanism, and at a much less expense.

Figure l is a side elevation ofthe core-bar or man-v diel, with the nut and chill in section, the chill being detachable from the bar, for the purpose of facilitating its removal aftenthe casting is made.

Figure 2 is a section o t' the mould in the plane of its parting, showing the core-bai', nut, and chill,l in position.

Figure 3 is a side elevation, partly in section, of a pedestal or plumber-block, with the prepared nut, pin- Ide, or adjusting-screw, chilled cup, and journal-box, in position.

(All the foregoing drawing have special reference to the use of a chill, in connection with a single nut and pintle or adji'isting-'sci'ew, under circumstances where means of vertical adjustment are unnecessary.)

Figure4 is a side elevation ot' a core-bar or mandrel, with-two screws upon it, for the reception of as many nuts.

Figure 5 shows a hanger, with said nuts in position within it; this latter drawing also showing two pintiles, one above and the other below the journal-box, thus rendering said box adjustable in a vertical direction.

A, ng. 1, is a metallic core, core-bar, or mandrel, a portion of whose periphery, B, is threaded to enter a nut, Cwhich has been previously tapped or chased, to correspond with the said threaded portion.

The core-bai' or mandrel terminates at one end in aY square head, D, to enable it to be removed from the uut, (or nuts, in case two be used,) after the casting of the body into which they are inserted, and when but one screw is employed, is, at `its other end, prolonged, so as to forml a tenon, with which to connect it with a convex-spherical chill,E, the purpose of said chill being o to form acorresponding concave chilled seat or bearing,

.1?, (iig. 3,) for the reception of the lower spherical portion of the journal-box F, but where two -adj usting-screws or piutles are employed, theV saidother end has another and smaller screw-thread, B', (fig. 4,) lto receive a second nut, C'.

The form shown in iig. 3, receives one screw, G, and that shown` in' fig. 5, receives two screws or pintles, G G', having the necessary concave spherical cups to fi the convex portion of the cap and box.

Our mode of construction is as follows:-

A pattern, with -its appropriate core-prints, having' ,core-bai', being subsequently withdrawn, the nut and chilled c'up, or the two nuts, (if that form be used,) are left permanently embedded in the substance of the casting, perfectly secure, in line, and ready for the insertion ofthe adj listing-screws or pintles.

In order to eifectually secure the nut or nuts within the casting, a number of small indentations, c, figs 1, 2, 3, 4, and 5, should be provided, into which the metal may flow, and thus prevent any possibility of its turning or becoming loose in case the adhesion of the nut to the body 'of the casting should-become defective.

We bave-selected, for il1ustration,the form successfully introduced by us, but reserve the right to vary the' same as cases or circumstances may suggest; for example, we do not consider the thread upon the mandrel as indispensable, or of vital 4importance to the successful use of our invention, as in many cases the nuts may be simply placed upon a plain, uiithreaded mandrel, said mandrel having been previously turned so as to properly tit the internal or smaller diameter ofthe nut, and a shoulder left upon it. to forni a guide by which to bring the nut or nuts into proper position.

` The core-bar or mandrel A, and chill E, are preferf ably made of cast-iron, that metal contracting and expanding mostuniformly with' the metal of the casting, but iii-point of dnrability, wrought-iron or steel may be preferred, especially for the lighter class vof castings. Either' of those metals will, however, answer the purpose.

We expressly disclaim any right, as inventors, to any part of the device known in mechanics as the ball-,and-socketor self-`adjusting joint or bearing, but

eonfine our claims exclusively to the application of the metallic core, core-bar, or mandrel, either with or without a thread upon it, and its insertion with its nuts, or with its nut and chill, into the mould, prcvious 'to casting, in such manner as to bring said nut or nut and chill truly into line, and ready for the reception of the adjusting-screws and journal-box without subsequent fitting.

We do not claim securing previously-prepared parts of a metallic structure by laying the same in a mould and casting other portions about them, the same being, as a inode or method of casting, well known among founders; but
