' lllllltours F. norm, or CANANEA, Mnxrcou CINDER-CAR.

To all whom it may concern: I g

Be it known that I, LOUIS F.1(UIIN, a citizen of the United States, residing atCana .nea, Sonora, in the Republic of Mexico, have invented certain new and useful Improvements in Cinder-Cars, of which the following .is a. specification, reference being had tothe accompanying drawings. y

This invention relates tocindercars used in connection with smelters for receiving and transporting molten metal and liquid cinder from blast furnaces and has i for its object to provide a novelsupplemental support for the trunnions at eachendof the car,whereby the weight'of the car and contents is partially taken from the bearing shaft and journal member for holding the same. f

Afurther object of thisinvention is to arrange the support of thisinvention so that it can be readily removed, replacedand inspected, as the conditions require. I "Another object of this inventionis to ar range the sameso that it can be manufacturedand installed at a comparatively low cost, and sothatwhen in position, will not interfere with the tilting action of the car they are placed on.

A still further object of this invention is to provide means whereby the weight will be taken off the sills proper that are used in connection with thisclass of cinder cars, so as to relieve the stress from the trunnions and prevent them bending under'the weight of the bowl of the same and its contents.

Other objects of this invention will be-,

come apparent as it is more fully set forth.

It is well known that the weight of the bowl and contents of a cinder car strains the bearing shafts that rotatab'ly hold the same, so that they are distorted or broken after a comparatively short usage- Of course these shafts could be strengthened by increasing the diameter thereof but such. a

method is objectionable for many obvious reasons. This invention is for the purpose of relieving the stress entailed in the design of the present style of cars used for the purpose, and also in orderto afford means of relieving the stress on the bearing shafts and supporting sills so that they will not be strained in any way by the weights referred to.

At the same time this invention consists in general of a simply formed member I Specification of Letters Patent. Application filed ()etober 14, 1911. Serial No. 654,625.

which can: be readily disposed onthe frame Patented Dec. 17,1912.

of the car and under the trunnions of the bowl so that the latter will be partially supported thereby, and yet not interferein any way withthe tilting action of the same. I

In the accompanying drawings which illustrate byway of example an embodiment of this invention, Figure 1 represents aside view of a cinder car embodying this invention,'taken from inside one of the wheels. Fig. 2 is a sectional view on the line 22 of Fig. l, and Fig. 3 adetailplan view of I '2 one of the supplemental supports embody-f ing this invention. Fig. 4 is a detail show ing the trunnions resting'on the supporting member.

Similar reference characters refer to simi larparts throughout the drawings.

r In the construction shown in the draw ings, 1 represents a bowl of .a-cinder car, the opposite ends of which" are provided with trunnlons 2, said trunnions being provided with tapered bores 3 which extend partly f into the same, as can be-ynoted in Fig. 1 of the drawings. A bearing shaft 4: having its innerendportion suitably tapered, is dis:

posed within the bore 8 and provided with a'lock bar 5 which-holds the same securely in position, suitable registered openings be- 1iOng provided in the trunnions for said lock ars.

, Suitable journal bearings 6 supporteach ofthe shafts 4 and any usual formoftilting mechanism is mounted upon one of the 1 supports, butforming no part of this in vention and therefore not shown in detail. The journal bearings .6 are carried by the cross bars 7 which extend transversely. of and are supported by the sills 8. The sills 8 extend beneath the journal boxes 9 mounted upon the axlelO carried by the wheels 11 of the car and are supported by the hangers 12 connectingsaid sills and journal boxes.

Itwillv thus be seen that the journal bearfings 6 which form the usual support for the trunnions transfer their loadto the sills 8 at points outside of the point of support of the wheels by the axles and there is consequently not only a tendency of the shaft 4 to bend under the load ofthe bowl and its contents but also of'the sills to give at their point of support by the axle under the bending stress.

The features of construction, thus far described, are of the usual type and do not constitute any part of the present invention which consists in the provision of means for relieving the bearing shaft and the sills of a great portion of the load.

A supplemental support 13 is mounted on the boxes 9 at each end of the car and has its upper portion 14: bent upwardly and rounded to form an arch as shown in the drawings in order to normaly support the trunnions 2.

It will be noticed from Fig. 2 of the drawings that the trunnions 2 are substantially oval in cross section so that when the bowl is in a vertical position the lower face of the trunnions will rest upon the arched portion of the supports 13 thereby relieving the bearings of considerable weight. WVhen the bowls are turned upon their axis the trunnions 2 will obviously be out of contact with the arched portion of the supports 13 thereby permitting the bowls to be easily turned for the purpose of emptying their contents.

Suitable holes 16 are provided in the lower and flat portions or feet 15 of each arch so that the end portions of the hangers 12 will extend therethrough and by means of nut-s 17 securely hold the same to the boxes 9. Extending from the curved portion of the member 13 to the outer edges of the same are webs 18 for the purpose of strengthening the same.

Thus it can be seen that the invention while of very simple construction afiords a means for transmitting a large portion of the weight of the bowls to the journal boxes more directly than is possible by the present means. The general shape of the supporting member in question is such as to permit its ready manufacture and installation and not interfere with the present existing parts of a car of the nature referred to, so that the same can be applied to a car without necessitating any structural changein the car.

Obviously while there is shown but one form of this invention in the drawings, it is not desired to limit this application for patent to that particular form, or in any other way otherwise than necessitated by the prior art, as many modifications in the construction thereof may be made without departing from the principles thereof.

Having thus described this invention, what is claimed is g 1. In a cinder car or the like, the combination, with the wheels, the axles, sills carried by the axles, journal bearings carried by the sills beyond the wheels, trunnions journaled in the bearings, and a bowl carried by the trunnions, an arch carried by the axle beneath the trunnions between the bearings and bowl and having an upper convex hearing face to support the trunnions intermediate their length.

2. In a cinder car, the combination with the wheels, the axles, sills carried by the axles, journal bearings carried by the sills beyond'the wheels, of trunnions being elliptical in cross-section and a bowl carried by the trunnions, a bearing shaft extending from said trunnions and journaled within the bearings, and an arch carried by the axle beneath the trunnions between the bearings and the bowl, said trunnions being adapted for rotation whereby when the bowl is in a vertical position the trunnions will rest upon the said arches and when the bowl is in a tilted position the trunnions will be free of the arches, substantially as described.

3. In a cinder car, the combination, with the wheels, the axles, sills carried by the axles, journal bearings carried by the sills beyond the wheels, of trunnions being oval in cross-section and a bowl carried thereby, bearing shafts detachably connected to said trunnions and journaled within said bearings, a support carried by the axle beneath the trunnions between the bearings and bowl, the said support comprising an arched medial portion having, an upper convexed bearing face, said trunnions adapted to be supported upon the convex bearing face of the supports when the bowl is in a vertical position and the said trunnions being free of the said supports when the bowl is in a tilted position substantially as described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
