To all whom it may concern:

Be it known that I, 'JosnPH D. Crrii, a citizen of the United States of America, residing at Dayton, in the county of Montgomcry and --State of Ohio, have invented new anduseful Improvements in Axle Bearings,

of which the following is a specification.

This invention relates to certain improvements in bearings for the axles of trucks or cars. More particularly the bearings are designed for use in connection with cars used for transporting V brick in brick-making plants. In such places the car tracks are more or less imperfect in their laying, there being more or less variation in the elevation of the rails and, therefore, it is desirable that the bearings for the axles of such cars shall be free to compensate or vary in accordance with the amount of deflection that is imparted to the axles of the car due to such unevenness or lack of uniformity in track elevation and plane. The present invention has for its object to provide an axle bearing for cars of this character which has both a maximum of anti-friction and a facility for oscillating .in lanes both parallel and transverse and in act any plane between planes that are ar'allel and transverse to the line of the ax e of the car. In other words, the

axle bearing is of the ball and socket or universal bearingtype with an elimination of a certain amount of the contacting surface between the two members whereby friction at some points is avoided, and the parts of the bearing may be easily disassembled and put together. The invention consists of the parts and their combination and construction as will hereinafter appear from the description and the claims to follow and 40 in connection with the accompanying drawn. the accompanying drawings which form part of the description to follow and upon which like reference characters indi 5 cate similar parts as they are illustrated in the drawings.

Fig. l is an end elevation of a car truck having my improved axle bearing in position thereon.

Fig. 2 is an inner side elevation of the bearing intact, detached from the truck or car frame.

Serial No. 579,047.

Fig. 4 isa bottom plan view of one of the bearings intact with'the axle broken awayto facilitate space.

Fig. 5 is asectional View on the line 5-5 of Fig. 3.

Fig. 6 is a sectional view on the line 66 of Fig. 2.

Fig. 7 is an end view of the ball or inner bearing member.

As hereinbefore stated, the invention is designed to afford the greatest range of oscillation of the bearing around the end of the shaft or axle which is received therein. This is important for the reasonshereinbefore stated; due to the imperfect alinement of the rails forming the track over which the car is moved and which are usually light. These cars, as before intimated, are used for transporting clay products in their making, such as bricks, tile, etc, for example in transporting the product in the green state to the kilns for drying the same.

Having these ends in view the particular description of the bearing is as follows:

'1 designates a bracket which is rigidly attached to the truck or car frame 2. This bracket is strengthened or'reinforced by a longitudinal rib 3 which is a well known ex? pedient in the molders' art. The lower portion thereof terminates in a shell or housing which constitutes the outer member of the bearing. This shell or housing 4 is of spherical form which spherical form 'extends from the upper portion thereof into the sides thereof. The top and sides form a rounded interior contacting surface which incloses the ball or inner member 5 of the bearing. The lower portion of the shell or housing 4 is omitted or removed so that the bottom thereof is open as at 6, and it is apparent that the weight of the car will keep contact between the bracket 4 and member 5.- As shown inFig. 4. the ball member 5 of the bearing is exposed through the open bottom of the shell, the upper portion thereof being in contact with the upper rounded portion of the said housing, as is clearly the axle 7; both in perpendicular and transverse planes as well as any plane between these two planes of oscillation. Therefore,

it follows that a. maximum of compensation-is provided in the bearing for all inequalities or irregularities of the track. The

axle 7 has a direct bearing in a series of roller bearings 8 which are assembled on the interior of the ball member of the bearing and these, together with the elimination of the lower portion of the housing 4;, provide a-minimum of frictional resistance at all degreesof oscillation which the axle may demand in passing over the car track.

.The opening 9 in the housing through which the axle projects in finding its bearlngis amply large to enable the greatest amount of oscillation of the ball 5. The wall 10 acts as a thrustbearing for the axle. The. car tracks in brick kilns are usually not laid by expert trackmen. The conditions are such that it would be impossible to lay such track perfectly owing to the lack. of a proper road. bed and other causes well known to: the brick-making art. Therefore, not only is there1found. lnequalities in the track due to higher and lower elevation of parts, butv often side deflections are present in these tracks and it is these various irreguinner bearing member ofspherical form within saidhousing, the lower sideof said ing or socket member the interior top and the interiorperipheral top wall thereof beserving as a thrust bearing for the end of the axle and aninner bearing member havmg a form .to fit within said housing, wherehousing.

inner bearingmember beinguninclosed at a the "bottom of the housing whereby it is subject to a universal movement within the housing with a substantial curtailment of frictional engagement with said housing.

2. The combination with a car axle, of a bearing therefor consisting of an outer housside walls thereof being; of a continuous spherial form and the bottom thereof being open throughout its width, a ball constituting an'inner bearing member within said housing and adapted to have universal range of movement therein, the lower side of said ball or inner member being exposed through the opening. in thehousing and saidinner memberhaving a series of roller bearings arranged therein which receive the car axle.

3, The combination with a car-axle, .of a bearing therefor consisting of a. housing ing in the form; of a frustum of a sphere and one ofthe side walls of the housing by it is" subject to a universal. movement within the housing ;witha.sub stantial curtailment of frictional engagement with said 4. The combination with a car axle, of a bearing therefor consistingbffan outer in. tegral housing or socket member the interior top wall thereof" being in the form of a frustum of a sphere and a side wall of the housing serving as a thrust bearing forthe end of the axle, a ball constituting an in: ner bear ng member within 1 said housing andadapted to have a universal range of movement therein', and' said inner member havlng-a series of roller bearings arranged thereinjwhich receive the caraxle.
