SPECIFICATION forming part of Letters Eatent N 0. 624,968, dated May 16, 1899.

Application filed February 6, 1899. Serial No. 704,755. (No model.)

To aZl whom, it may concern:

Beitknown that I, JAMES A. PEEK, a citizen of the United States of America, residing'at \Vest Plains, in the county of Howell and State of Missouri, have invented certain new and useful Improvements in Hub-Attaching Devices; 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 an improvement in hub-attachin g devices; and it is embodied in the construction and the arrangement of parts hereinafter described, and defined in the claims.

The aimand purposeof the invention are the provision of means for attaching wheels to axles, such as carriage and wagon axles,

without the necessity of forming threads on the axle-skein and securing member.

Many attempts have been made heretofore to accomplish the above-stated object; but the devices suggested have beenin their nature somewhat complicated, intricate, and possessed of a multitude of parts, which render the same obviously objectionable. In my improvement I have overcome these objections and have provided a device which will serve the purpose well, be cheaply manufactured, and strong and durable.

In the accompanying drawings I have shown an embodiment of the invention, but desire it understood that changes in the spe cial form and arrangement can be made without departing from the nature and principle of the invention. a

Figure 1 is a side elevation of the end of an axle, showing the improvement applied thereto. Fig. 2 is an end elevation showing the attaching device adjusted to lock the hub on the axle. Fig. 3 is a longitudinal vertical section taken through the line w as, Fig. 2. Fig. 4c is an elevation of the ends of the axle or skein. Fig. 5 is arear view of the looking device. Fig. 6 is an end view of the locking device, showing parts of the lockingwasher broken away to expose the interior or space between the washer, also showing parts in dotted lines. Fig. 7 is a view of the inner washer, showing the springs in position; and Fig. 8 is a rear elevation of the locking-washer.

the part B. the base of the part B and is formed with the In the drawings, A designates the axle or skein having the attaching end B, oblong in shape and formed with the fiat side I). At

diagonally opposite points at the base of the ing-surfaces are produced, having the overhanging portion c, which is slightlyinclined.

The cams O are located at the inner end of The axle or skein is beveled at locking-recesses b, oppositely arranged and located at the smaller ends of the cams C.

' D designates the base-washer or holdingring,havin g a circular opening in thecenter, the inner walls of which are chamfered, as at d, and provided with locking-lugs d, fashioned to engage in and be held by the walls of the recesses b'.- The outer face of this ring or washer is formed with the curved channels D having fixed abutments d arranged diametrically opposite each other. Within the channels are placed the coiled springs E, one end of eachrestin g against an abutment. It will be readily seen that the washer D can be readily removed from the axle, but when in position cannot turn, owing to the lugs engaging in the recesses of the axle.

F designates the locking-washer, conveniently circular in form and having curved recessesff in its inner face fashioned to corresppnd in shape and size substantially with the recesses or channels in the part D. The recesses in this washer F have the oppositelyarranged stops f, the vertical faces of which are arranged to face the vertical faces of the stops of the washer D. Between the stops are placed the coil-springs, the ends abutting,

respectively, against the stops, so that as the inclined outer faces g, corresponding, substantially, to the inclination of the outer walls of the cam-grooves of the axle-skein. The distance between the straight side of the locking-walls is substantially the same as the diameter of the end B of the skein, but sufficiently greater to allow the movement of the part B through the intervening space. The locking-shoulders are located at the inner edge or face of the ring F and register or are in alinement with the camgrooves of the skein when the parts are in position. By forming the locking-shoulders with the inclined and straight faces and arranging them in line with the cam-grooves it will be readily seen that by turning the'washer F the locking-shoulders are forced into the cam-grooves and when properly turned are wedged tightly therein. This movement is effected by the tension of the springs between the washers, the stops being so placed that the tendency of the springs will be to turn the lockingshoulders into the cam-grooves and hold them therein.

In the outer face of the locking-washer are form ed two oppositely-arranged sockets H, in which the ends of a suitably-fashioned key or spanner can be placed when it isnecessary to turn the ring againstthe tension of the springs for releasing the device.

To prevent a separation of the two washers or rings, any convenient means can be employed. I have shown ears K, struck up or formed on the outer edges of the basewasher, projecting forward, and bent down over the edges of the locking-washer, the same being bent after the parts have been properly adjusted.

In operation, the wheel having been placed on the axle or skein, the locking device is sleeved over the end B, the flat inner face of the base-washer resting opposite the hub and against which the latter turns, the outer washerhaving been turned so that the straight sides of the locking-shoulders are parallel with the straight faces of the part B of the axle, thus allowing the lugs of the base washer to enter the recesses in the skein or axle. While in this position, the locking-washer is allowed to be moved by the springs, which carry the locking-shoulders with a wedgifig action into the cam-grooves, thus locking the base-washer firmly in place and preventing an outward movement thereof, while the lugs thereon prevent the turning movement in either direction. The construction and arrangement of the lockingshoulders and grooves are such that when the locking-plate is turned to its limit of movement the propelling-springs will be under tension, thus serving to maintain the parts in close union and prevent any rattling or accidental displacement.

The particular construction of tool for unlocking the device is not of primary importance, as it is evident that many means can be devised for accomplishing that purpose.

Where I have used the term axle in this case, I desire it understood as being sufficiently comprehensive to include the axle proper or an axle-skein.

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

1. In a hub-attaching device the combination of an axle having a reduced outer portion formed with inclined grooves, of a basewashe'r on the axle, interlocking means between the washer and axle for preventing independent rotation and a spring-actuated locking-plate on the washer having inclined lockingshoulders arranged to engage in grooves for preventing the outward movement of the washer, substantially as described.

2. In a hub-attaching device the combination with an axle having an extension at its end formed with two flat sides and oppositelyarranged grooves, of a base-washer on the axle, means for locking the same against rotation, a locking-plate having locking-shoulders engaging in said grooves and springs interposed between the washer and plate for forcing and retaining the locking-shoulders within the grooves,substantially as described.

3. In a hub-attaching device, the combination with an' axle having inclined lockinggrooves therein, of a base-washer fixedly held against rotation on the axle, a locking-plate connected with the washer, locking-shoulders on the plate arranged to engage the grooves and a spring for holding the shoulders in a locked position within the grooves, substan tially as described.

4. In a hub-attaching device, the combination with an axle having locking recesses formed therein and inclined grooves adjacent its outer end, a base-washer having projections entering the recesses and having circular channels in its outer face provided with oppositelyarranged stops, a lockingplate having corresponding channels in its inner face and oppositely-arranged stops, springs in the channels between the stops of the washer and plate, and locking-shoulders on the lockin g plate registering with the inclined grooves of the axle for the purposes specified.

5. In a hub-attaching device, the combination with the axle having a reduced portion formed with flat sides and inclined grooves, of a base-Washer fixedly held against rotation on'th'e axle, a locking-plate secured to the washer having locking-shoulders formed with flat edges and inclined outer faces and a spring interposed between the washer and plate for holding the locking-shoulders within the grooves, substantially as described.

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

JAMES A. PEEK.
