SFEGIFIOATILON forming part of Letters Patent No. 678,744, dated July 16, 1901. Application filed March 18,1901. Serial No. 51,815. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH R. KINLEY, a citizen of the United States of America, residing at and whose post-office address is Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hub-Attaching Devices, of which the following is a specification.

My invention relates to means for attaching wheelhubs to babycarriages, velocipedes, and similar articles; and its object is to provide an inexpensive and commercially satisfactory means whereby hubs may be readily and removably secured; and it consists in the features of construction and combination to be hereinafter more fully described, and pointed out in 160131111 hereto annexed.

Referring to the accompanying drawings, wherein like reference-letters indicate the same or corresponding parts, Figure I is an elevation, partially in section, of a portion of an axle provided with my improved device, which is shown engaging the hub and holding it in position. Fig. II is an elevation, partially in section, showing the method of releasing my improved device from engagement with the hub. Fig. III is a plan view of a portion of my device to be hereinafter more fully described. Fig. IV is a perspective View of the parts shown in Fig. III after the same have been bent into proper form. Fig. V is a sectional view taken on the line 5 5 of Fig. IV and viewed in the direction indicated by the arrows at the ends of said line.

I am well aware that several devices have I been described,- patented, and put into practice for removably engaging hubs to baby- 'carriages and other conveyances, but I am not aware, nor do I believe, that anysuch de vices anticipate the invention herein described and claimed.

Heretofore locking devices of a similar character have been composed in part of a casting and in part of a piece of spring metal, which required to be riveted to the casting. Others have been composed of a number of cast parts and controlled by a coiled spring, while still others have been so constructed as to necessitate mathematical accuracy in the adjustment and manipulation of their parts. All of the devices referred to cost more in time and material to manufacture than the device of my invention and by reason of the presence of one or more cast parts are much more liable to be broken.

Again referring to the drawings, A is my improved hub-engaging device,which is pivoted at a to the axle B. The hub O is one of common form and provided with a pocketed or hollowed end 0 and is constructed in such manner that it will readily slide upon the bearing Z) of the axle, the hollowed end 0 of the hub being innermost. When it is desired to secure the hub upon the axle, the holder A is adjusted to the position shown in Fig. II, following which the hub may be slid upon the bearing until the shoulder Ct of the holder is within the recess 0 of the hub, and thereafter the long arm at of the holder may be pressed toward the axle, the cam-operating portion a of the holder serving to raise the spring-arm ct upon the end of the bolt Z), which boltwhen the holder is in the position shown in Fig. I engages the lock aperture or slot a thereby locking the holder to the axle and retaining the shoulder Ct within the recess 0, thus securing the hub to the axle. To remove the hub from the axle, it is but necessary to reverse the operation above described.

In the device of my invention I form the engaging member A of a single piece of sheet or plate spring metal, stamping it out in blank, as shown in Fig. III, and thereafter bending it at the points indicated by the dotted lines in said figure into the form shown in Fig. IV.

The lock-aperture a may be situated at or approximate to the end of the spring-arm a and may be substantially round or of any .suitable shape; but I prefer that it be of substantially the elongated form shown in the drawings, as by so constructing it the bolt 12' need not be positioned with mathematical precision upon the axle, but may be situated only approximtate to a given point, and by so forming the lock-slot which makes it possible to engage the bolt even though the position of the latter be slightly varied in different axles I effect a great economy in time in the manufacture over that which would be required were it necessary to locate the bolt with mathematical exactness, as will readily be seen. This bolt, which passes through the axle and is secured thereto by a nut 12 may in event of its wearing be readily removed and another substituted therefor, in addition to which it prevents the spring-arm a of the holder from coming in contact with the axle and wearing the same. This bolt may also be employed to secure a spring or the framework of the vehicle to the axle in addition to its office as an element in the locking means, thus effecting a still greater economy in the manufacture, and this economy forms an important part of my inven tion.

Though Iprefer to employ the bolt as above described, it will be understood that in place thereof a clench pin or rivet may be used,

mama

signify a bolt, pin, rivet, or similar securing device.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a hub-attaching device, the combination with an axle, a hub thereon, of a spring-arm having one end pivoted to the axle adjacent said hub and adapted to enter an annular recess therein, the opposite end of said arm having an elongated slot therein, a downweirdly-projecting portion below said slot having a cam-surface, a bolt passing through the axle and having a nut thereon adjacent said slot, whereby the end of said bolt is adapted to engage the cam surface and enter said elongated opening, substan Lially as described.
