CARRIAGE non salir-ACTING MULES.

Application ledFebruaiy 22, 1921. Serial No. 446,986.

To a-ZZ whom t ma@ concer/t:

Be it known that I, HENRY PLATT HALL, a subject of the King of the United Kingdom vof Great Britain and Ireland, and resident of Toravon l/Verneth, Oldham, in he 4countyfof Lancaster, England, have invented new and useful Improvements in Carriages for Self-Acting Mules, of which the following is a specification.

` This invention Vconsists in carriages for self acting mules constructed wholly or in great part of steel ork other metal plate and constructions and devices to -be applied in them which in comparison with the carriages heretofore made wholly or in great part of steel or other metal plate or sheet and the constructions and devices applied in them, afford the advantages that lin proportion'to their weight, the `carriages have greater strength, rigidity' and capacity to withstand the strains and shocks of use and are better altogether andthe construction of carriages of the various lengths requisite is made more practicable.

For the attainment of these advantages the invention, relating to carriages constructed wholly or vin great part of steel or other metal plate, consists in devices and constructions to be applied in such carriages which are hereinafter 'to be described and particularized in the claims,

According to this invention a continuous box girder of steel or other inet-al plate is provided as the main structure on which the other parts of a carriage of a self acting mule are mounted.

The box girder is constructed cf any suitable number of sections of suitable, and advantageously equal, length connected oneto another after formation to build up a continuous box girder of the length requisite for a carriage to be formed.

Although plates of other metal may be i used steel plate will ordinarily be used in the formation of carriages according to this invention and so in the description following steel plate will generally be mentioned for simplicity.

In the accompanying drawings, Fig. 1 is a vertical section through part of *a carriage of a self acting mule showing one construction of box girder, the means for connecting the carriage bearers and one form of rest for the spindle rail or spindle box. 2

is a front elevation of some of the kparts shown in Fig. 1. Y

Fig. k3 is a transverse section through part of a carriage'showing another construction of box girder.

Fig. 4 is a front elevation illustrating parts lat :and near the junction of ltwo sections or portions of the length of the carriageshown in Fig. 1.

Fig. 5 is a transversesection through part of a carriage comprising aV box girder of theconstruction show in Figs. 1 and 2 and shows in side elevation one .of the bearing brackets, for thetin roller `shaft and the means by which the bearing bracket shown is fixed in-position.

Fig. 6 is a section illustrating a jogged spindle rail rest riveted to the front wall of a section of a carriage and Figs. 7 and 8 are sections illustrating jogged spindle rail rests.

The same numerals of reference `are employed to indicate corresponding parts in all the figures. A A

In one construction of continuous box girder mule carriage illustrated Yby Figs. 1, 2,V 4t and 5 according to rthis invention the requisite number of sectional lengths I, of

which only one is shown in Figs. 1,2 and 5, y

and parts of two` are shown in fl may be made up by way of example: primarily of a bottom plate 1 with lupwardly directed flanges at the front and back to form the frontr2 and back 3 of the section I and atop plate 4 provided with upwardly directed flanges 5, 6, along the edges to extend lengthwise of the section. The top plate is placed and riveted in position between the front and back of the section and the bottom plate having the flange 2 extending above the flange 5 has secured to it by'rivets 'l' an upper plate 8 to extend vertically on the front wall and upwardly therefrom and beyond the top plate l and furnishedY at an appropriate height above the place of attachment of the plate 8` with a rearwardly extending inclined flange 9 serving in the completed carriage as a rest for the spindle rail or spindle box 10 and forminga simple means of providing a rest at any height requisite and easily to kbe taken away and replaced by another plate if after a carriage'has been constructed it is necessary or desirable to provide a flange at a dierent Vheight 'for' spindles of dierent 'zoV Q. i i

plates 8 shown, other similar plates with flanges 9 at a different height, the rivets 7 securing them can be easily removed without interference with the fastening of any parts other than the plates 8 but, if it is convenient in any cases the plates 8 may be secured by the rivets used in securing together the front 2 and top 4. f

The plates 8 are shown as presenting plane front surfaces but if desirable in any case, for the sake of greater stiffness inthe plates 8 and consequent stiffening to the carriage front or for any other reason, the plates 8 may be jogged to present on each face parts in two approximately parallel planes so that the upper parts will be brought further towards the front or further towards the rear of the carriage than in the case shown in Figs. 1, 2, 4 and 5.

In Figs. 6, 7 and 8 illustrative examples of jogging are shown. Fig-.7 shows a spindle rail rest 100 jogged at'101 so that each face presents parts in two parallel planes and the upper part is further to the rear than the lower and Fig. 6 shows such a spindle rail rest 100 riveted to thefront wall of a mule carriage section 102.

f Fig. 8 shows a' spindle rail rest 103 jogged at 104 so that each face presents parts in two parallel planes and the upper `part further forward than the lower.

Thefronts 2 of the sections I to be joined together and the pla-tes 8 if attached to them may be made to meet throughout the adjoining parts, but if, as is preferable a plate or sheet 11 of metal to be described hereinafter is to be interposed between the meeting parts of the sections I the fronts 2 to be oined and the plates 8 if attached to them are made to meet in their upper parts and cut away in their lower parts so that space is provided for the plate 11.

ln anotherconstruction of continuous box girder mule carriage according to this invention and illustrated in Fig. 3. the sectional lengths II of which only one is shown may be made up by way of example: pri.- marily of top and bottom and front and back steel plates marked respectively 13, 14.

'i 12. 15 riveted together, of which the top and bottom steel plates 13, 14 are provided respectively with upwardly and with downwardly directed flanges marked 16, 17 respectively along the edges to extend lengthwise of the sections II. The back plate 15 is a plain plate to which other parts may be `attached and the front 12 is made to present an extension 81 extending upwardly beyond the rivets 71 securing the top plate 13 and furnished with a rearwardly directed inclined flange 91 serving in the completed carriage as a rest for the spindle rail or spindle box.

In each of the constructions hereinbefore described the top plates a or 13 of a section may be of the same length as the bottom plate 1 or 14 but, if either be the shorter, it may be secured to another or others in any appropriate manner as for example by the parts to be joined `together being furnished with flanges or angle bars upwardly directed in the case of a top plate or downwardly in the case of a bottom plate, secured one to another immediately or with the interposition of a transverse plate or a flanged plate riveted to the bottom or top or front and back or both to the bottom or top and front `and back to stiften the structure.

In each of the constructions hereinbefore described the rivets for securing together the longitudinal edges of the top and bottom plates or top and bottom and front and back plates are outside the ,internal cavities of the sections and any rivets to enter those cavities at parts inaccessible from the ends may be applied before the plates are riveted together.

A section of a continuous box girder to be placed next the square at either side of the headstock of a self acting mule may be made with a top, bottom and side of steel plate thicker than, for example, twice as thick as that used for other sections.

According to this invention in order that one section of a continuous box girder self acting mule carriage may be coupled to another adjoining it, or a section may be attached to a square of a self acting mule or that a section to form the end ot a carriage remote from the square may be adapted to have an end plate secured to it, each section is provided externally at each end with right angled flanged metallic attaching parts presenting only longitudinal bearing faces and having the two outer bearing faces at right angles for one to bear against the section and the other to bear against a part for connection with said section and formed with holes for bolts. The right angled flanged metallic attaching parts may be in the form of angle plates or flanged brackets and are riveted to it at the top and bottom or the front and rear or to it at the top and bottom and flanged brackets riveted to it at the front and rear or a flanged plate riveted at the top or bottom and at the front or rear or front and rear to present holes formed in their flanges opposite to holes in the flanges of similar right angled metallic attaching parts on the section or to holes in the square to which it is to be joined or end plate to be joined to it. Preferably the right angled metallic attaching parts on the bottom of a section are riveted thereto before the top plate is riveted in position. Bolts passed through the holes in the anges of angle plates or flanged bracketsor the right angled metallic attaching parts riveted to a section are used to secure one section to another or to `the square of a mule carriage or an end plate to the section as the case may be. A steel plate to extend from front to rear between the meeting faces of sections to be joined together may be provided to add rigidity to the continuous box girder and to be secured in position by the bolts securing the sections together and the plate so used may serve also to carry any other part or parts.

Fig. 3 showing one end of the section II shows flanged plates 18, 19, riveted respec tively to the top 13 and bottom 14 of the section and flanged brackets 20, 21, riveted respectively to the front 12 and back 15 and a metal .plate or sheet 11 corresponding in outline with the outer edges of the hanged plates 18, 19 and flanged brackets 20, 21 and the end of the section II. The flanged plates 18, 19 and the flanged brackets 20, 21 are so formed and riveted in such positions on the section II that they present faces in one plane and in the same plane as the ends of the plates or sheets forming the top 13, bottom 14, front 12 and back 15 of the section II.` The flanged plates 18, 19 and flanged brackets 20, 21 being provided with bolt holes and corresponding bolt holes being formed in the plate 11 bolts 22 are passed through these holes and holes in Aflanged plates and flanged brackets on the section and corresponding to the plates 18, 19 and brackets 20, 21 and are provided with nuts which being tightened secure the sections firmly together, the plate 11 stiftening the section.

Figs. 4 and 5 illustrate flanged plates 119 riveted on the bottoms 1 of the sections I and flanged brackets 120, 121 riveted respectively on the front and rear 2, 3 respectively of the sectionsI and a plate 111 secured between the flanged plates 119 and flanged brackets 120, 121 of the two sections I by means of bolts 22 passed through holes in the flanged plates 19 and flanged brackets 120, 121 and the interposed plate 111, the plate 111 being shaped to correspond with the outline presented by the outer edges of the flanged plate 119, flanged brackets 120, 121 and the meeting parts of the sections joined together, and as in the construction shown in Fig. 3 the plate 111 stilfens the section I.

The flanged plates and brackets corresponding to those described with referencel to Figs. 3, 4 and 5 serve also for the attachment of the continuous box girder car- 'riage to the square of a self acting mule which will be provided with holes in appropriate parts of the framework for the attaching bolts but advantageously the angle plates or brackets used for connection to the square may extend for a greater length on the front or rear as the case may be of the `section than the corresponding parts at the other end of the section.

The section to be at the end of a self acting mule carriage remote from the square mayr serve for the attachment of the end plate to be there provided which obviously will be provided with holes in appropriate places for the bolts requisite.

According to this invention in order that carriage bearers may be secured in any positions requisite upon continuous box girders used in mulecarriages angle bars 23 are e provided on and in the preferred const-ructions made as shown in Figs. 2 and 4 to extend along sections of the girders and channel bars 24 with parts of the flanges made to extend as ears 25 transversely from the ends, are applied with the flanges upwards transversely on the bottoms 1 on the Ysections I of the box girders and riveted or advantageously bolted to the angle bars 23. The ears 25 are shown as formed with holes through which the rivets securing the channel bars 24 to angle bars 23 are passed. In a preferred construction the angle bars are provided as shown in Figs. 2 and 4 with holes at equal intervals along their length so that the channel bars24 may be attached to any of a number of places. The channel bars 24 are provided with holes in which rising screws 26 of any convenient form as screws, bolts or studs attached to or serving for attachment of the carriage bearers 27 are secured and preferably to facilitate the application of the rising screws if the holes for them should be accessible from one side only in use as in the case shown in the.

each end with a hole and communicating slot. to serve respectively for the passage of they head and the passage of the shank of a rising screw 26, the three rising screws being connected to the carriage bearer' 27 in an ordinary manner. When the ychannel bars 24 'have been applied on the bottom 1 or 14 of the section I or II of the carriage and secured to the flanges or angle bars 23 the heads of the three rising screws are introduced through the holes intothe spaces within the channel bars 24 and the shanks are slipped into the communicating slots and secured therein by means of the nuts`28 and the rising screws are adjusted and se-V cured in position in the carriage bearers 27V in the ordinary manner for the sections I,

Il of the. carriage'to be supported in the manner requisite by the wheels ot the carriage bearers 27. Other channel bars 24 like the two shown are applied wherever convenient on the sections I or Il and elsewhere on the carriage for the connection of carriage bearers.

` According to this invention in order that bearing brackets for the tinroller shafts may be inountedand made adjustable upon the continuousbox girder carriage oi a self acting mule channel bars 29 with partsof the flanges niadeto furnish at the ends ears 30 at right angles to the bars are applied with flanges downwards transversely on the top plates 4, 13 oi the sections l, or ll ci the box girder are riveted or bolted at their ends to the plates ot each section. Each channel bar 29 is made to bear one of the bearing brackets 31 for the tin roller 32 to extend along the girder, the bolts or studs 33 for securing the bearing bracket 3l to the channel bar 29 being introduced into the holes provided for them through a gap formed in one ot the flanges oit the channel bar 29 but if convenient yin any case the channel bar 29 may be provided with holes and communicating slots to allow passage respectively for the heads and the shanks of the bolts 33 which may then be passed from above through the holes and into the slots in it. Brackets 34 secured to the channel barsfby means or' rivets, by means of bolts passed through holes with communieating slots like those aforesaid or in any other way or other means may be provided to afford screw threaded holes or other appropriate bearing tor screws 35 with lock nuts for adjusting and fixing the adjustment of thebearing brackets lengthwise of the channel bars 2 Y nFurther according to this invention in order to provide for the attachment of the tie rods for adjusting and lining the position of the spindle rails or spindle boxes l() angle bars 36 made to extend Yfrom front to back of sections formed in any oit the ways hereinbefore described are riveted inY position preferably to the top platev` by means of one flange, and brackets 37 generally similar in their upper parts to those used for providing attachment for the upper tie rods on wood mule carriages which are adapted at their lower parts to be litted and secured by bolts to the angle bars provided in their upper parts with ears with suitably formedA curved faces and holes allowing sutliciently free passage for the upper tie rodst7` so that the nuts on the tie rods 38 may be made to fix them in any position into which they may be swivelled in adjustment ofthe spindle rails or spindle boxes 10 on the bracket 37 may be' furnished with eye bolts ork studs providing attachment in which the upper tie rods 38 are mounted to swivel and secured by nuts in the arms of the brackets. Eye bolts or studs 89 are mounted to swivel and secured by nuts in the angle bars 36 to provide attachmenttor the lower tie rods 40. In modilications of this construction other means tor attaching the tie rods to the brackets and angle bars may be employed.

Longitudinal rails 41 secured to the several mountings tor the tie rods 38 of the spindle rails or spindle boxes l0. the square o't the headstock and the end plates of the carriage as the case may be are provided for the support er attachment of the rear edges ot tcp covers l2 and the upper edges ot rear covers 43. y

The longitudinal rails 4.1 are formed of sections bolted or riveted together into continuous rails.

The top covers 42 are 'termed o1t` steel sheet in convenient lengths and oic widths sutlicient to enable them to overlap to the extent necessary the upper spindle rail or spindle boit l0 at the trout and the longitudinal supporting rails il at the rear.

In the case illustrated the top covers 42, of which only one is shown, are provided at the rear with 'lolded edges #ist to embrace the edge of the rail Ll1 ant at the front with a beaded edge to rest on the spindle rails or spindle boxes l0.

In the ease illustrated the rear covers 43, of which only one is shown are made of steel sheets and made to slide in grooves in the brackets 37' and bent rearwardly at the lower parts to rest upon the section I ofV the continuous box girder and provided on their inner faces with ears 45 to engage the upper rear fianges of the sections to prevent the covers 43 from being displaced rearwardly and on their upper parts are provided with forwardly bent parts 4:6 to bear upon the rails 41.y

F ront covers 47 may be made of sheet metal in convenient lengths in any way convenient and made to overlap or to enter or to be engaged in any convenient way with the front walls of the sections.

The spindle rails or spindle boxes l0 are advantageously formed of longitudinal wood rails connected by metal or other` brackets.

This inventionv may be applied to a self acting mule with a carriage at both sides or only at one side of the headstock, the construction applied in any case in which there is a carriage at only one side of the headstock being equivalent to that applied at the part or' a carriage at one side of the headstock of a sel-t acting mule having a carriage at both sides of the headstock.

The taller relieving motions and middle drawing out tightening arrangements which are of ordinary construction and therefore not shown may be supported by any con- Sti venient means for example., brackets much like those ordinarily used on wooden oarriages of self acting mules for carrying the fallei' relieving motions and middle drawing out tightening arrangements and riveted to the upturned parts of or at the front and rear of the sections of a mule carriage to angle bars provided at the bottom. The faller shaft and counterfaller shaft which are of ordinary construction (omitted from the drawing for simplicity) may be carried in upi'iglits riveted or otherwise secured in convenient positions to the sections of the carriage or to parts applied thereon. Y
