ANTIFRICTION-BEARING SPECIFICATION forming part of Letters Patent No. 607,790, dated July 19, 1898. A iiaum filed October 1, 1897. Serial No. 653,765. (No model.)

To all whomit floaty concerm.

Beit known that I, JAMES C.REBER,acitizen of the United States, residing at Reading, in the county of 'Berks and State of Pennsylvania, haveinvented certain new and useful Improvements in Antifriction-Bearings Used in Bicycle Construction; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a bicycle or velocipede crank-hanger of that class in which a crank-shaft with integral crank-arms and pedal ends is mounted and rotatably secured in place by specially formed or constructed antifriction-bearings.

The object of the invention is the construction of a hanger that will permit the placing therein or the removal therefrom of such a shaft with integral crank-arms and pedal ends without first unscrewing parts from the'ends of and without opening a slot or space lengthwise in the tube or sleeve of said hanger.

The elements of the invention will sever; ally and at large appear in the following description, and theywill be separately and collectively set forth in the claim.

The purposes of the invention are attained by the mechanism and devices illustrated in the accompanying drawing, similar reference characters designating like parts throughout the several views, in which- Figure 1 is a sectional view of a hanger embodying the elements of the invention, showing the shaft with portions of integral crankarms in place. Fig. 2 is a similar view of said hanger, showing progress in the introduction or in the removal of said shaft. Fig. 3 is an enlarged sectional view of the bearing detached from the left-hand end of Fig. 1, and Figs. 4, 5, and 6 are detail plans showing halves of elements detached from Fig. 3.

The hanger A of the invention is practically the same as that well known in bicycle construction, comprising a tube or sleeve A,

I which is inserted into the ends of the tube A,

while an outwardly-projecting ring-flange Z), resting against the edge of said tube, serves to hold said race in place, keeping it from entering farther into the tube. Onto the shaft A is screwed a cone B having at its outer end a prescribed ring-flange I), provided with an-inwardly-extending peripheral wall b inside of which is located a ball-race, into which are placed the required number of balls B and around the center, at the inner end of the cone, is formed an annular recess, into which is placed a tubular projection 19 from an outwardly-projecting ring-flange B extending aprescribed distance over the balls, or to about, the center thereof, constituting I the ball-retainer of the invention, and serving to keep the balls in place when thecone is removed for any purpose whatever, while the ball-race B aforementioned serves to complete the bearing. Of course the central aperture of the cone must be sufficiently large to allow the cone to pass freely over the angles where the shaft and crank arms are joined. It will here be observed that one bearing is applied to each end of the tube A, their cones being secured in place by jam or look nuts I).

Now an inspection of Fig. 2 of the draw ings, a cone having been removed from the shaft, clearly shows that said shaft may be readily removed from or inserted into the hanger without disturbing the ball-race in the tube or dropping the balls from the cones.

Having now described the invention and fully set forth the manner in which it is performed, what I consider as new, and desire to secure by Letters Patent, is-

The combination of an axle or shaft having integral cranks, a sleeve or hub, ball-races fitting in the ends thereof, cones engaging the axle andeach having a recess in its inner Intestimony whereof I aflix my signature end produeingan enlargement of its bore, in presence of two Witnesses. 7
