Description
ttm-td stica HIPPOLYTE ULYSSE PETIN, 0F RIVE DE GIER, FRANCE.
Lette/rs Patent No. 107,194, dated September 6, 1870 1 'IMPROVEMENT IN MACHINES FOR ROLLING` TIRES.
The Schedule referred to in these Letters Patent and making part of the same I, HJProLYTE ULYssE PETIN, of the firm of Hte..
Potin, Gaudet 86 Go., metallnrgist, of Rive de Gier, 1u the Empire of France, have invented an Improved Machine for Rolling Metal Tires, die., of which thefollowing is a specification.
Nature amt Objects of the Invention. I
My invention relates to the manufacture of Tires, 86e., trom rings of forged or cast meta-l and vMy invention consists of a machine, in which the said rings are subjected to the action of certain rollers and a mandrel, operating as fully described hereafter, so as to compressively actnpon every face 0f the rings. Description 0f thc Accompanying Drawing. Figure 1 is a sectional view of the machine 5- vFigure 2, a sectional plan view; 'Figure 3, an elevation, showing a modification;
Figure 4, a sectional plan of tig. 3; Figures 5 and 6, views illustrating ordinary modes of manufacturing tires, &c. and
Figure 7, a sectional'view, illustrating one mode of making the rough metal ring or blank, from which the tire is to be formed.
General Description. Y In suitable bea-rings turn two 'parallel metal rollers, f y, the bearings ot the lower roller, f, being vixed, and those of the upper roller sliding vertically between guides in the fra-me M of thev machine., and to the front end of the roller j' is secured a disk, c, the edge of which, in the present instance, is of the form shown in iig. l.
.'lhe projecting end of the4 roll g, directly above the disk c, is reduced in diameter, for aptirpose described hereafter, and to the frame M of the machine is scf,
cured a rest or platform, It. which occupies a position in front ofthe disk c, and level with the horizontal face x of a projecting portion of said disk.
-In 'an arm, E, projecting from the frame M, and in astep, F, at the base ofthe machine, turns a vertical mandrel, B, which is secured at the upper 4end to a cord or other device, by which it can be elevated, so as to withdraw it from its position in front of the disk c, and between the latter and the plate h.
Before proceeding to describe my improvmeut, I will first brietiy refer to the ordinary modesof manufacturing heavy tires and similar articles, and the disadvantages resulting from these modes. which I overcome by my improvement.
1n some instances an iugot, G, (tig. 5,) is pierced at two points, a b, and is slit between these points, and a series ot' mandrels is forced successively into the slit, widening the latter gradually, so asto forma single ring. This is then rounded on a mandrel by a trip? hammer, and reduced-as nearly as possible to a uniform thickness.
Another mode consists is casting a 17mg, X, of steel,
(tig. 6,) and then stamping or pressing the ring be-y tween dies E E', repeating the method whenever it is necessary.v The ring is theurolled between the rolle-rs, pressing against the inner aud'outer edges only.
Both of these operations are tedlousaud expensive,
and fail to reduce the ringv to that perfectly uniform thickness desired. l To overcome these didicultles I first forma ring. either by welding from a t'agot or by casting. latter case I use a flask, the sections of which are serrated at the inner sides, as shown in tig. 7, so as to retain the sand, the ringbeiug deeperor higher than` those used in the ordinary modes of manufacture.
. The ring thus obtained -is then heated and placedupon theplatt'orm h, one edge resting on the projection x of the disk c, the end of the roller g resting ou the opposite edge ot' the. ring, and the mandrel `B extending through the same, as shown in gs. 1 and 2;l a rotary motion is then imparted to the rollers, when the ring will be caused to revolve betweenthe bearing surfaces of the same, which press upon all the faces of the ring, the weight ofthe roller g gradually reducing the height of the ring, and pressing it against the 1 l edge of the disk c, which forms the outer face, coustitut-ing the edge-or tread of the tire. Y
By thus operating with revolving rollers on all the faces of the`riug at one time, the operation of reducing it to the proper form is speedily accomplished with little labor andfexpense, and the product is more uuiform in shape and better in quality than tbat'from the ordinary process of manufacture.
The disk c may in some cases be dispensed with, and the ring may be compressed directly between the Aprojecting ends of both rollers f g, an additional ver tical mandrel, D, being used, as shown in figs. 3and 4.
N After the operation is completed the mandrel B is removed and the ring withdrawn, and, if necessary,
subjected to such other operation as may be required to complete it.
If required, the rollerg may be forced against thel ring by a screw or other device, instead of byitsA weight.
Claim.
The rolls f g, the projecting outer. ends of which are constructed to form the sides and tread of a'tire,
in combination with the roll-B Afor rolling the inside of' the tire, whenthe said roll is arranged substantially as
