SPECIFICATION forming lpart' o'ffLetters Patent No. 373,777, dated November 22, i887.

I' Application filed June 24,1887. Seal No. 242,401.. (No model.)

` To all whom it may concern.- Beit known that `JAMES. J. KIRBY, a citizen of the United States, formerlyresiding at Moline, county of Rock Island, State of Illinois, deceased, has inventeda newand useful Machine for Forming 'Wheel-Rims, of which the following is a specification.

The object of this invention is to construct a machine for forming the rims of car-wheels Io by rollerpressure.

The peculiarities, utility,aud novelty ofthe 'invention are below described and claimed.

In general terms the main essentials of-the machine consist in a set of three rollers for `I54 formingan internal dangeon one edge of the `wheel-rim and a setof two rollers for forming the external ange ofthe tread part of the Wheel, and duringthe operation these sets of rollers act separately and conjointly in per- 2o formingdift'erentfunctions,as belowexplained.

In the drawings forming a part of this specification,Figure 1 isa side elevation with parts broken and the wheel -rim`in section; Fig. 2, a plan' with parts broken away; Fig. 3, broken 25 lettered details of Fig. 1, enlarged; Fig. 4, a

plan of parts in Fig. 3, with the roller-axles in cross'section below the rollers, the latter be- "ing shown in dotted lines; Fig'.4 5, a broken piece of the wheel-rim prior to its subjection 3o to the machine; and Fig. 6 is the' same after treatment, these two last figures being in perspective. l

Referring to the lettered parts of the drawings, A. is the top ofthe machineframe,and A 3 5 is the` bottom thereof. At y y' are two shafts gear-connected, having bearings in the frame,

and are provided at the upper en'ds wit-h rollers ct'ct. The roller a conforms in shape to the exterior of the wheel-rim B when completed,

4o4 and the `roller a conforms in shape to the interior of said rim. To this end the rollerais .flanged at the top and tapered at the-base.'

The roller a' is dared outat the base to conform tothetaper of the other roller, a. These portions ofthe roll rs a a form the external flange I of tlic 'wheel-rim. Their form in Figs. l and 2 is such that the flange is formed scalloped; but as this is a matter of vchoice the terms tapered and flared 7 as used above are deemed sufficiently specific. It will be ob- 5o served that the roller a is shorter than that portion of the roller a below its flange. Thus in'use the flange z projects overjthe end of the roller a', leaving a space between said end of the roller and the iiange corresponding to the v,thickness of the metal from which the vrim is made. v At u u are two like shafts', also gear-connected,asinFig.l. Theseshafts are provided at the top with rollers c c. The periphery of these 6o rollers is straight vertically, or nearly so, except that they are out away at the base to accommodate the' external ila-nge of thevwheela'im.

The internal iiange, It, (see Fig. 6,) of the -wheel-'rim is formed by crimping the edge 65 over theu-pper edge of roller c while the rim revolved between the rollers c c' by means of the conical roller S, Fig. 1, .which -is brought to bear against the upper outer edge of the metal, which is vertically straight, Vas in Fig.

5, and as the metal yields a continuous and increasing pressure of the roller S is brought to bear upon it until it is nally at right angle to the tread part of the wheel-rim, as shownat the rightof Fig. l. f 5

Any suitable means may be employed to-opcrate the roller S. It is shown attached to a 'curved swinging bar, T, having end bearings..

rollers c c', and the metal band is placed be- 9o` tween theserollers of each sct. The rollers c C'. are then brought to bear against-the band and the machine setin motion. Thefrictional v engagement of these rollers with said band causes it to revolve. has been' formed by the roller S, as before stated, then the rollers a a are brought to bear against the band or rim until it is bent to form After the internal Harige tagt the external iange,h as appears in Figs. 1 and 3. These flanges can be formed without having the two sets of rollers in, position to receive therim between the rollers a e' and c c' at the same time; but this would necessitate taking the rim from one set and-placing in another, whereas, as here shown, the rim does not have to be removed until it is perfected. Besides, by allowing the operation to continue after the iianges are formed unevenness and irregularities in the desired true circular form of the wheel-rim are overcome. The shafts y y and u u have bearings at the lower end in pivoted rocking blocks m, Fig. 1. By this means the shafts can be separated to separate the rollers when putting in the rim B and when desiring to take it ont. Both Sets of shafts can be tilted slightly to properly locate the rollers. Aswell can the shafts of either set he tilted independently of each other.

Fig. 4 clearly shows the means for tilting the shafts and holding them at desired positions. To the bearing of the shaft y at the upper end, and to a cross-head swiveled on screw 2, are pivoted the draw-bals c, one on each side.

lThis scnew has threaded bearings in the machine-frame. By turning the handle or rather wheel V the angle of shaf't 1/ can be changed, and hence the position ofthe roller a' as well. The bearing o1 the shan; -1/ has screw-connections with the screw 1, said screw passing through a screw-threaded hole in the screw 2, the latter-named screw being, of course, hollow. By turning the wheel r of screw 1 the shaft `1/ may be tilted.

In the operation of tbl-ming the external fiangeofthe wheel-rim ll the, wheel rand screw 1 are turned to gradually force or press the roller u against the rim, which yields a little at a time until it is finally crimped, as shown in Fig. A great advantage of these screws asa means othandling the shaft and rollers is that it can be quickly donc and with great accuracy, and the rollers are rigidly held at any given point of adjustment.

Like rollers and screws are duplicated on the other side ot` the machine to handle the i shafts u u' and their rollers.

these rollers maybe dispensed with, if preferred. to the brackets- 3 3, and lluse brackets are connected at the upper ends by 'a shall. s, which has screw-threaded ends passert lt rough screw-threaded holes in `said brackets. By loosening the nuts whieh hold the brackets The-axles ot` these rollers are attached and turning the shaft 4 the rollers F F are adjusted laterally. In Fig. 1 is shown how the shafts are gear-connected with the power-shaft 5, (shownpbroken in Fig. 2;) but any other suitable propelling mechanism may bc employed.

It may be mentioned that it is not always necessary that the shatts y u should have bearings which enable them to be tilted, and with accurate construction and proportionA of parts perhaps never, but desirable, however, for contingent needs.

Having thus described the invention, what is claimed is- 1. In a machine for forming wheel-rims,the combination of two revoluble rollers adapted to receive and revolve the whcelrim between them, a conical roller, and means t'or sustaining a pressure ot' said roller against tfie edge of thewheel-riin in *forming the interna flange, substantially as set forth. t

2. In a machine for forming wheel-rims,the combination of two revoluble rollers adapted to receive and revolve the wheel rim between them, two revoluble rollers, one tapered and the other tiared at the base, and adapted to receive the wheelrim between them, and means for sustaining a pressure of' said rollers against the revolving wheel-rim in forming the external tlange, .substantially as set t'orth.

3. In a machine for forming whccl-rims,the combination of the revoluble rollers adapted to receive and revolve the wheel-rim between them, the conical roller, and means tor sustaining a pressure of said roller against the edge ot' the wheel-rim in forming the internal flange, the. revoluhle rollers, one. tapered and the other fiarcd at the base, and one of them being longer than the other and flanged at the top, said rollers adapted to receive the wheelrim between them, and means t'or sustaining a pressure of' tl1ese.rollers against the wheel-ri m in forming the external flange, substantiallyv as set forth.

L In a machine foi ie. .ning wheelrimsahe combination ot' the sets of rollers const rncted and arranged, as set f'orfh, to l'orln the intel'- nal llange and external flange of the wheelrim, and means for operating them, and the single idle-rollers adapted to contact the inner surface ot' the revolving wheel-rim, substantially as set t'orth. y
