AXLE-NUT.

SPECIFICATION forming part of Letters Patent No. 727,757, dated May 12, 1903.

Application filed November 14, 1902. Serial No. 131,396. '(No model.)

To all whom it may concern.-

Be it known that I, WILLIAM'O. DE MA- RENO, a citizen of the United States, residing at Westfield, in the county otOrleans and State of Vermont, have invented certain new and useful Improvements in Axle-Nuts 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 wagon-nuts; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan view of the wagon-nut. Fig. 2 is an end view. Fig. 3 is a sectional plan view. Fig. 4 is a longitudinal section taken on the line'xa; in Fig. 2.

A is the end portion of the bearing of a vehicle-axle, and B is a cylindrical projection at the end of the bearing, having a hole b formed crosswise through it.

C is the nut-body,' which is 'revoluble on the projection B. c, which extends through-its sides and end. The nut-body is conical externally, and it has a circular rib d near its smaller end, which has notches e cut .in it, so as to form lugs f at the sides of the slot 0.

D represents beveled portions att'ne ends of the slot.

E representscatches which are pivoted in the side portions of the slot 0 upon pins g, which pass through the, said lugs f. These catches have projections h for engaging with the end portions of the hole I) and have also stops 1,, which engage with the beveled portions D. The outer portions of the catches conform in outline with the exterior of the nut-body, and E represents handle portions Which project rearwardly beyond the end of the nut-body.

G is a dovetailed bridge-piece which is secured in dovetailed grooves 1c in the endof the nu t-body crosswise of the slot 0.

H is a bent spring, the middle portion of which is secured to the bridge-piece G before it is inserted in the dovetailed grooves.

The

This nut-body has a slot.

end portions of the spring bear against, the handle portions of the catches and hold the projections in engagement with the hole 1?. The middle portion of the spring is secured to the bridge-piece by logs j on the bridgepiece, which are hammered or pressed over the edges of the spring, so as to hold it securely.

The not is slipped onto the projection B and is revolved until the projections of the catches slip into the end portions of the hole b.

The nut is removed by pinching the handle portions of the catches between the thumb and fingers and then pulling the nut off the projection 13.

This wagon-nut or axle-nut is constructed so as to be finished as much as possible by machine-tools and so that very little hand fitting is required in assembling its parts.

What I claim is-' I 1. The combination, with the end portion of an axle provided-with a cylindrical projection having a cross-hole in it, of a slotted nutbody which is revoluble-on the said projection, said nut-body being conical externally and provided with a circular rib near its smaller end having notches in it so as to form lugs at the edges of the slot ofthe nut-body, and spring-pressed catches pivoted in the side portions of the said slot between the said lugs and provided with projections for engaging with the said cross-hole, substantially as set forth.

2. The combination, with the end portion of an axle provided with a projection having a cross-hole in it, of a slotted nut-body which I against the said spring, substantially as set is circular externally, a bridge-piece secured forth. 1o

crosswise of the said slot in grooves in the In testimony whereof I aflix my signature end of the nut-body, a spring carried by the in presence of two Witnesses. 5 said bridge-piece, and catches pivoted in the WILLIAM C. DE MARENO.
