This invention relates to rails used'in spinning and twister frames to support the bear-' ings or boxes for the Spindles. Usually these rails are called spindle'rails or box rails, and they will be referred to hereinafter by the latter term.

It has been'customary heretofore to make box rails bya metal casting process. Each spinning or twister frame requires at least three railsections, namely, a head section, a foot section, and an intermediate section. Also, different models and gages of frames require diflerent designs of'rail'sections and there must be a separate casting pattern 1 for each section of each gage and length of trame ."-="'lhis obviously requires the use of a large number of patterns. After a box rail casting'has been made 'it'must then hemachined on its upper, lower and rear'faces,

' which combined with theicost of casting, in-

volves a relatively" expensive method of manufacture. The expense is further in creasedby'the fact that there'is'ja high percentage of defective castings'due to the p g culiar shape and design'of'the rail'sections.

The present invention aims to improve the construction and methods of manufacture of box rails with a view to reducing the expense of manufacture while at the same'time providing-a superiorconstruction. f y

' The nature of the invention will be readily understood from the following description when read-in; connection with the accompanyi-ng drawings, and the novel features will be 5 particularly pointed out in' the appended claims." w

In the drawings, Figure 1 is a perspective view of a series of parts which preferably areu sed in building a box rail according to the present invention;

, Fig. 2 is a front view of'a part of abo'x rail constructed in accordance'with this inven tion-' I 3 is a horizontal sectional'view of the '45 railshown in Fig. 2, the section being taken substantially on the line Fig. 2;

'Fig. 4 is a end view'of the rail shown in a .1;

F5 5 is arirontview of portions of said m p the box rail I Figs, 6 and? are vertical sectional views on the lines 66 and 7 -7, respectively, Fig. 2;,and Y r liigs. 8 and 9 are sectional views on the lines 8-8 and 99, respectively, Fig.

' The present method proposes to eliminate thecasting-process entirely and to make up sections from metal parts of standard shapes. 7 7 I v 1 I Referring first to Figs. 2f'to 9, it willbe seenthat the rail section A there shown comprises upper and lower rail members 2fand 3,. respectively, extending longitudinally of the rail in parallel spaced relationship, 'l heseniembersare of angular form in' cross sectionand usually are called angle irons. Connecting these members'atspaced inter vals are a series of cross barsindic'a ted by the numerals 4, Sand 6. Fig. 2 shows both an end section A and part of'an intermediate section B of a box rail, and the sectiontA' includes an end ands, which isset at right angles to the other bars. All ofthese cross barsare weld; ed at their opposi-te'ends toxth'eupper and lower rail members. 2 and 3, respectively. It will be observed that onefian'ge of each of the rail members projects horizontally when piece or bar'7,"i l3igs. 2, 4

the rail is in its operativeiposition, and'that the other two flanges of said members he in substantially the same vertical plane; and

extend toward each other.) Also,'fthatthese members are held permanently in this relationship by the cross bars, and that' thebars, 4 are butt welded to the vertical flanges, While the bars 5 and 6 are overlapped upon the vertical flanges and Welded to them in this relationship. i Y

The various before being assembled are shown inFig. 1.

parts of the rail section A All of these partspreferablyare of steel" of v standard rolled forms. In atypical in stance the angle iron members 2 and '3 ma be, say, seven-sixteenths of an inch in thickness andone flange may have a width of approximately one and one-half inches while the other is, say, two and one-half inches wide. The bars "4: correspond infthickness was stock used in the rail members 2 and y i 3, but the bars 5 and'6 are made somewhat" thicker. All of these parts are. cut to suitable lengths, no other preliminary shaping vbeing required except on-the bars and 6.

The angle iron members 2 and 3 may conveniently be placed in a suitable form or fixture to hold them in the desire-d relationship while the cross pieces orbars'are arc welded to them. An electric are preferably, although not necessarily, is used for this purpose.

All of the cross two rail members 2 and 3 in spaced relationalso serve the additional function of taking ship to each other, butthe bars 5, 6 and 7 the bolts which secure the rail to the samsons or. other frame n embersof the spinning or twister frame. Forthis reason the bars 5*are spaced apart by a relatively nar-.- row vdistance suitable to receive the bolts 8, Figs. 2 and 3, which clamp tion. to the sainson 9. The bar 6 is located closely adjacent to, but spaced slightly from,

the end of the rail section A and the other section 'B has a bar 6 similarly located, so that when the intermediate and'end sections A and B aremounted in their normal posisamson 12. The fact that these bars 5 tionsin'the frame, these two bars 66 provi-de a slot between themwide enough to accommodate the bolts 10 which secure the end jportions of these two sections to the v and 6 are made somewhat thicker than the'bars 4 and have rearward surfaces lying behinr the plane of tlierearward faces of the upright flanges of the" rail members 2 and 3 serves to properly space or position the rail with reference to the samsons.

The end bar 7 of the rail section A is drilled totake'thelbolts by which it is sochine, Preferably thisbar is, setback slight-- secured to the end frame piece of the maly' from the end faces of the rail members 2 and 3', as best shown in Fig; 5, and a small piece. or block 14', Figs. La and 5, is welded tothe central part of" the bar 7 to serve as abearing or fillerpiece between this bar and the frame. 7

When-the welding operations have been completed the horizontal flange of the upper rail member :2 is ground on its upper surface. and holes, such as those indicated at 15, Figs. 4 and 6, are punched or drilled through this flange to receive the spindle boxes or bearings. The rear surfaces of the bars 5 and 6 and the extreme end faces of the rail usually also areomachined, and

holes are drilled for the guide rods for the ring rail. 'These are, however, the only'machining operations. usually performed on the ;It h'asbeen definitely determined'fin actual practice that this invention effects a very substantial saving in the total cost ofmanufacture ofa box rail.
