Application filed November 13, 1916. Serial No. 131,102.

To all lr/iomit may concern:

Be it known that we, Orro H. Jonsm and JAMEs H. Gnrswonn, both citizens of the. United States. and respectively residents of Cleveland and East Cleveland, county of Cuyahoga, State of Ohio, special administrators of the estate of RICHARD S. BRYANI, late a citizen of the United States, and resident of Cleveland, Ohio, deceased, (as by reference to the duly-certified copy of letters of administration heretofore filed for the purpose of record will more fully appear,) believe said RICHARD S. BRYANT to have in vented a new and useful Improvement in Machines for Sizing which the following is a specification, the principle of the invention being herein ex plained and the best mode in which it. was contemplated applying said principle. so as todistinguish it from other inventions.

The present improvements relate to a de vice for sizing a transplit annulus and are particularly designed for use in sizing vehicle Wheel rims ot' the transplit type. lt is customary in this operation to place the annulus upon a. suitable mandrel of such a size as to permit the ends of the annulus to abut against each other. When the annulus -is in such position, other means, preferably a plurality of radially movable blocks compress the annulus against the mandrel, thus properly sizing the same and rounding out any irregularities in the shape of the annulus. The dilliculty with such a machine is that during this compression the ends of the annulus forced against each other, oftentimes in such av way as to mar these two ends, and it is to prevent this injury to the ends or edges of the annulus that. the present invention is designed. complishment of the foregoing and related ends, said invent-ion. then, consists of the means hereinafter fully described and par ticularly pointed out in the claims.

he annexed drawings and the tollowing description set forth in detail certain mecha; nism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings Figure 1 is a broken plan view of a tire- Transplit Rims. ct

To the a o therein; Fi 2 is a vertical section of such machine, the plane of thesection being indicated by the line 2-2, Fig. 1; Fig. 3 is a. plan View on a larger scale than Fig. 1, of the portion of the machine which includes the aforesaid improved features of construction; Fig. 4 is a vertical section taken on the plane indicated by the line P Fig. 3; and Fig. 5 is a similar vertical section taken on a parallel plane as indicated by the line. 5--5, Fig. 3. a

In the several figures there is shown a mandrel 1, of suitable material, which will preferably be formed of a diameter slightly greater than the desired internal diameter of the annulus when. finished; Upon this mandrel there is placed the annulus 2, (see Fig. 2), and by reason of the diameter of the mandrel, the ends of the annulus will not contact but will be separated by a slight space. The present invention is, of course, designed to operate upon any type of annulus, but as stated above has been particularly intended for use in sizing transplit rims of the type used, on motor vehicle Wheels which must be very accurately di mensioned and which" must. not be injured at the ends during the operation, and it is such a rim which IS'SlflOWIl in Fig. 2 of the drawing.

Any desired means may be employed for compressing or sizing the drel, such for radially movable bloclrs t, of which several are shown in Figs. 1 and 2, where the features of construction of interest herein are shown as incorporated in a tire-setting machine of otherwise familiar construction. These blocks are operated by any desired rim upon the man" means, usually by fluid pressure of some sort,

center of the mandrel and the block. In the present illustration, this is the movement given to the said block; 5, and is occaexample, as a plurality of cutting the annulus. .made to move in a direction parallel with end, as shown.

sioned by the nature of the ends of the rim 2, since this rim is cut at ,a slight angle to a-padial line passing through the point of cutting or upon a plane forming a sector The block 5 is therefore against each other during the compression of the rim upon the mandrel. The size of the spacing shield 6, is determined by the diameter of the mandrel with respect to the desired diameter of the rim, this shield being proportioned to contact with the ends of the rim when the latter is forced smoothly and evenly against the mandrel at all points. The mandrel 1, is provided with a suitable aperture 8, formed as a slot be- I tween two blocks 9, 9, set in spaced relation ini'a recess 10 in said mandrel, and there held in place by means of set bolts 11, 11, adapted to receive the projecting end of the spacing shield as the latter moves through the rim u on the compressing movement of the blocfis 4.

In a tire setter of the kind in hand the compression blocks are loosely connected to the actuating lungers and it is thus possible for the although the other blocks operate radially as usual. This is possible since the lateral, or rather circumferential movement imparted to the block 5 by its plane of movement is too slightto bring it into the radial path of movement of the adjacent blocks.

By means of the present machine it is possible to properly size any trans-split annulus of the type shown without in any way injuring the ends of the annulus. In fact, the spacing shield coeperates with the block 5 to properly form the ends of the annulus if they have been slightly compressed during anyprevious operation in the manufacture of the rim.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as the invention 1. In a device of the class described, the

lock 5 to move in a planealined with the plane of the ends of the rim,

combination of a mandrel adapted to re-- ceive thereon a trans-split annulus, said mandrel being of. a diameter greater than the internal ,diameter of such annulus,

means for compressing the latter against said mandrel, and a shield. abutting against the ends of such annulus for preventing deformation of the same during such compres- SlOIl.

3. In a device of the class described, the combination of a mandrel adapted to receive thereon a trans-split annulus, said mandrel being of a diameter greater than the internal diameter of such annulus, means for compressin the latter against said mandrel, and a shield operated by said means to space the ends of such annulus apart and prevent deformation of the same during such compression. 1 I

4. In a device of the class described, the combination of a mandrel adapted toreceive thereon a trans-split annuluasaid' mandrel being of a diameter greater than the internal diameter of such annulus, a plurality of radially movable compression blocks operating to force such annulus against said mandrel, and a shield'attached to one of said blocks and adapted to be inserted thereby between the ends of such annulus to properly space the same and prevent deformation during such com ression. I

'5. In a device of the class descri ed, the combination of a mandrel adapted to receive thereon an annulus, transplit in a plane forming a sector across the same, 'said mandrel being of a diameter greater than the internal diameter of such annulus, a,

plurality of radially movable compression blocks operating to force such annulus against said mandrel, a shield attached to one of said blocks, the ends of such annulus are being positioned against said shield and said one block being thereby guided to move in alinement with the plane of the ends'ot said annulus.
