WHEEL `1VI1LL.

Application filed August 27, 1921.

which it appertains to make and use the same.

My invention relates in general to 1mprovements in the nconstruction of wheel `mills which are adapted to roll metal car wheels or other similar annular bodies, but for the sake of convenience of description herein I will refer only to wheels.

I-Ieretofore mills of this character have had a framework formed of a large number of parts, secured together `by bolting or othewise, the front Aof which was .only bolted to the base plate forming' flexible cantilevers, these and the other portions oll the structure carrying` the working parts,`

whereas I make a solid front framework connected at the top and bottom to the base and top framesto make a rigid construction.

lVith the prior constructions the springing or looseness of the framework allows the working portions to move from their proper' places or out of adjustment, thereby spoiling the work, -and in addition to this the prior constructions have been of such a character as'to require a large amount of time and labor in making changes and necessary adjustments of rolls. In order to obviate this I form the front portion of my apparatus substantially integral, tied together above and below, and mount upon it the working parts in such a way that the stresses of use are taken up by the solid front framework without the maladjustments above referred to, thereby makinga compact and solid structure which holds the working parts in position at all times.

Although I have shown my front `frame work as composed of vtwo sections, this is so drawn merely for the purpose of ease of making the castings and machining the saine, and these two sections are held together -by a very few bolts, and when the front frame so composed is secured together and to the other parts of the framing it is substantial- 5 ly integral.

Serial' No. 496,124.

I may, however, make the front frame completely integral and omit the flanges, separator and bolts which secure the two halves together, thus making it entirely integral and in one piece and well adapted to withstand the stresses and strains of use.

In addition, my construction is of a simple character andmy front framework, comprising front apron and headblock portions, is secured to the other parts, such as the rear frame and the base plate, by quick-acting bolts, so that it can be disassembled for replacement and adjustment ofthe working parts and reassembled in one-third the time that is required with the old'structures.

Vith the Told structures any movement of the headblocks or similar portions lin relation to each other or to the working portions, such as web rolls, back or tread rolls, or guide rolls will cause the wheel which isr being rolled to become nonuniform in dimensionsand in consequence it is rejected and is only scrap, whereas with my construction the working parts are held so firmly in position that these troubles are entirely obviated.

In prior constructions the minor in and out adjustments of the edging rolls were ob- Vtainedby mounting them on eccentric pins,

which pins when rotated slightly move these rolls inwardly or outwardly as desired, but this adjustment was insuflicient and shims were required to line the brackets of the edging rolls, necessitating much loss in time and labor. This construction has been improved by me whereby I mount the edg- I ing rolls on adjustable Shanks with screw movement of suiicient extent vfor all adjustments longitudinally.

Another difficulty with the prior type of edging rolls is the fact that in rolling wheelsV of different diameters the edging rolls were non-adjustable in a direction approximately radial to the wheel, with the result that with wheels of different diameters the angularity of the axes of the edging rolls caused pulling and tearing action on the wheel rim, which distorted the wheel and produced slivers on it. I obviate this difliculty by mounting my edging rolls so that their axes can be adjusted with respect to the radius A of the wheel, the rim of which is thereby rolled approximately on circumferential lines, thus obviating the destructive action above mentioned, and lthis avoids the dragging and consequent slivering of the wheel rims.

In addition to this the edging rolls are not required to be the same distance apart from the center line for all wheels on account of the varied design of different wheels, and my method of separately adjusting these edging rolls applies itself readily to this requirement.

In my construction the right and left hand sections of thefcombined headblocks and apron forming the front frame are substantially integral vwith each other, and theirfrelations to each other and other portions are such as to firmly maintain them in position and thereby hold the working portions mounted therein in rigid adjustmentas desired, and the headblocks or aprons each have integral pads on which the wheel mandrel rest-s and these are integral .withthe.framework which carries the edg- .ing and guide rolls.

The front-apron, which comprises the headblocks and wheel j mandrel supports, supports the edging rolls withtheir adjusting mechanism and carries the guid rolls, is incorporated substantially as one unit, so

l thatit may be easily, quickly and securely Y attached to or detached from the top and bottom plates of the mill frame, which j thereby reduces the time necessary to change the'working parts and insures proper relai tive alignment thereof.

-In addition to the difficulty of fslivering the rims and the destruction ofthe metal of the wheel in prior practice, my adjustment of the edging rolls to the substantially radial position of their axes with respect to the wheel, also eliminates excessive wear on theedging rolls in addition to 'preventing slivering due to their` incorrect position.

- Having thus givenl a general description lof my invention, I will now, in order to .make the matter morey clear, refer to the annexed two sheets of drawings, which form part of this specification, and in which like characters refer to like parts.

Figure 1 is a side elevation of my improved wheel mill; Figure 2 is a vertical o sectional elevation of the apparatus taken on the line II-II of Figure 1; Figure 3 is a detail view showing` the mounting of one -of the idler gears which meshes with a pinion on the drive shaft and a gear on the shaft of the adjusting screw for advancing or retracting the edge roll brackets; Figure 4 is a detail view of the indicator dial; Figure 5 is a detail view illustrating the position of the web` and tread rolls when in operation; Figure 6 is avertical ylongitudinal sectional elevation of one of the edge rolls, the edge roll bracket for holding the same, and the adjusting means for the edge rolls; Figure 7 is a horizontal longitudinal sectional elevation of the mechanism shown erence on the drawings: 1 indicates the rear framing of the mill in general; 2 are the slideways thereof upon which the tread or back r'ill is mounted; 3 is the tread or back roll; 4 is the front frame or head block composed of two sections, having the mandrelA supports integrally combined with the other portions thereof. The right and left hand sections of these portions 4 are secured together by the bolts 5 and 6, which latter are provided with separators or spacers 7 as illustrated.` S are keys or projections between the main f ame and the headblock 4 adapted to hold these parts in proper relative position. 9 is the support and guideway for the arbor or mandrel on which the wheel in process of rolling is held, formed integral with the frame 4; 10 are wearing plates `or shims in the guideway for supporting the arbor and more or less of these are used or they may be of different thicknesses and removable and replaceable to accommodate wheels of different sizes and diameters; 11 is the mandrel or arbor on which the wheel and blank is mounted during the process of rolling. 12 indicates the wheel blank, which is of smaller diameter than the finished wheel, in position for rolling and 13 are the edging rolls which operate upon the rim of the wheel and are adjusted inwardly and outwardly and to radial position. '14 are the shafts on which the 105 edging rolls are rotatably mounted; 15 are brackets which support the edging roll shafts; 1.6 are the shafts or adjustable shanks of the edging roll brackets adapted to rbe adjusted inwardly or outwardly or rotated within their supports to produce the radial position of the roll axes as desired. 17 are sleeves mounted on 16; 18 are sockets in portions of the headlock or front frame 4 which receive the sleeves 17. 19 is a feather H5 key slidably connecting the portions 16 and 17; 2O is a nut mounted in the shank 16,

'which, in connection with the adjusting screw 21 and attachments is adapted to feed the shank inwardly or outwardly to adjust l?" the edging rolls as necessary; 22 is a collar on the screw 21` to withstand the thrust thereof and on the extending end portion 23 of the screw 21 is mounted the gear 24. 25 is a pipe for feeding grease or lubricating oil to the moving portions. -A flange 26 is attached to or part of the adjusting sleeve 17, in which are formed a number of bolt holes 27 as illustrated, through which bolts 28 are passed in order to secure the parts in 130 the rela-tion desired. 29 is a flange on part ot the mill training which also has a series et holes therein. These holes in the iianges 2G and 29 are in staggered relation with more holes in one portion than in the other, so that by moving the parts one hole regis ters With another hole and the holt inserted so that adjustment can be made ot the edging rolls 13. By means ot this adjustment, the axes of the edging' rolls can he set within tivo or three degrees. 'lhe flange 26 is provided with a socket 30 in which a bar can be inserted to rotate it as desired for adjustment. The shank 1G is mounted in the bushing 17 in suoli a manner that it may be moved endivise therein, and hy reason of the feather it can he rotated vfith the bush ing 17. Integral bosses 31 are also provided, in which are mounted stud bolts 32 provided with collars 33 and on which the idler gears 34 are mounted and secured, these being arranged to gear with the pinion on the drive shaft 3G. The stud bolts 32 are provided with Washers 37 on their outer ends as illustrated. 3S is an indicator dial adapted to show the position et' the edging rolls, which dial may be graduated temporarily Afrom time to time to suit the ivorlr. This dial is provided with an indicator hand Si) mounted on the cylindrical projection The drive shaft is provided with driving gear generally indicated as 41, operated by the motor 43 geared thereto. are the web rolls which are converging and tapered as illustrated and provided with driving means (not shown).

Referring now to Figure 9, vvliioh shows an alternate arrangement ot adjustment tor the edging' rolls z-this is provided with journal hearings 44, in which is mounted a Worin 45, provided vwith a manually operated crank a-rin The sleeve 17 is provided with a flange 47 formed as a sector oi a `worin wheel and provided with ina "ginal teeth 4G which engage ivitli the thread of he Worm gear 45. 47 may also be provided ivith slight corrugations 48 and corresponding corrugated ivashers 49, which, when the sleeve 17 is adjusted by means ot the cranlr frm 52, can be securely clamped in place by means ot the bolt 50, the corrugated Washers 49 and the oorrugations et the 'flange 47. The flange 47 is also provided With a curved slot 51 through which the bolt 50 is passed. By means of this mechanism l can adjust the radial position of the edging rolls to the traction of a degree.A The corrugations may be omitted it desired. v

Thelwheel after or during rolling is 53, as shown in dotted lines, ot expanded diameter greater than the blank due to rolling` thereof', and my apparatus is iur-ther provided with guide rolls 54, and in Certain cases only one oi these may be needed, but in other cases two may be used as illustrated,

these guide rolls being mounted in l the brackets 55, 'which carry the pivot support ing bolts 56. 57 are loolts which secure my iii'iproved front `trame to the other parts et the training and lor the purpose ot rapidly removing the trame and changing rolls some ot these bolts have their heads introduced into T-slots, so that a slight turn on the nuts will allow them to he slid in and out ot position in the slotted lugs, While other bolts may have eye heads Yon pivot lxolts, around which they may be turned 'when the nuts are loosened, and others are usual through-bolts requiring, however, only the screwing or unscrew'ing ot a nut with a teiv threads so that all are quick-acting tasteniiigs, and as ll have only tori bolts which secure the entire trent trame to the other structure, the liront trame very easily loosened and talceii aivay from the other parts and as ea y secured in place ag .lo talco oli' the iront traine l slide the couj 'ig' to the lett, loosen or take otli' the nuts trom the bolts rotate er slide some et the ten holts 57 and then remove the :trout trame and the reverse operation will install it in place again. ily means oiI my construction l can make the change in one-third 'the time previouslv refpiired.D
