ROTARY WEAR RESISTING STRUCTURE.

UNITED STATES PATENT OFFICE.
WILLIAM H. 'SAYBE, OF GLEN RIDGE, NEW JERSEY, ASSIGNOR TO AMERICAN ABRA SIVE METALS 00., A CORPORATION OF NEW YORK.
ROTARY WEAB-RES'ISTING STRUCTURE.
To all whom it may concern:
Be it known that I, WILLIAM a citizen of theUnited States of America, residing at Glen Ridge, county of Emex, State of New Jersey, have invented certain new and useful Improvements in ,IRotary lVear-Resisting Structures, of which the following is a specification.
My invention relates to the provision of wear resisting surfaces for rotary elements of mechanism such as pulleys, feed rolls, conveyer belts, traction wheels, etc., which surface shall have toa limited degree in addition to its wear resisting qualities, the features 0f-resiliency and flexibility which are desirable in many cases. The best forms or embodiment of several typical phases of my invention are illustrated in the accom panying sheet of drawings in which,
Figure 1 is 'a side view of a pair of feed rolls equipped with my invention, the shafting or journals being shown in cross section.
Fig. 2 is a similar view of a pulley and belt, parts being broken away.
Fig. 3 is a similar view of a conveyer belt, and
Fig. 4 is a cross section of the casing of a pneumatic tire for vehicles having my in- .-vention applied as a tread.
Throughout the. drawings like reference characters indicate like parts. In Fig 1 is .shown a pair of feed rolls. 2, is a roll or pulley in each case, which may be made of metal or Wood or other material. 3, is a plate or bar being fed forward by'the rolls 2, 2. In Fig. 2 is shown a belt i, running over pulley 2. In both these figures of drawing 1, is a surfacing composition comprising a quantity. of granulated or finely divided mineral of great hardness, such as alundum, set in and on a matrix which adheres to the face of the pulley or roll. Preferably this matrix includes vulcanized rubber, the fine or soft rubber and sulfur of which has been intimately mixed with alundum, and the whole trued up before or during; vulcanization of the mass, which vul- Specification of Letters Patent.

a secure union with the This arrangement may secured in several different ways. The method usually followed is to first lay in the mold a thin layer of pure rubber, then'superpose on this one or more layers of rubber ground up and mixed'with different percentages of alundum particles, and finally to place a layer of pure alundum particles on top. sure these layers are solidified into a homogeneous mass in which the percentage of alundum per unit of volume of the mass increases gradually from bottom to top. This mass is then vulcanized. Pulleys equipped with my invention would be especially useful in car lighting equipment where the electric generators are mounted under the-[car body and driven from the car-axle by belts and pulleys. I
In Fig. 3, the conveyer belt 5, running over pulleys 2 and 6, is provided on its working face with strips or panels 7 of the above described character. This division into separate strips or panels enables the belt to run around the pulleys without pulling the outer more brittle wearing surface apart as might happen otherwise if the facing of alundum and vulcanized rubber were continuous, on account of the greater length of the semi-circle throu h which the outer surface of any very their belt so formed travels.
In Fig. 4, there isshown at 8', a cross secalundum and vulcanized rubber composition to serve as a tread therefor. Here, again, the layer 9, could be vulcanized in situ, or initially manufactured by vulcanization separately on a proper former, and then at tached to the shoe by further vulcanization or b any other suitable method. Mg invention could be similarly applied to elastic tires ofother than the pneumatic type. 1
Having described my invention, I claim: 1.' As a new article of manufacture a wear resisting machine element adapted for rotation comprising a supporting structure to the outer surface of whlch isattached a relaportion of the mineral particles being localpglley or roll proper. t
