DETACHABLE UMBRELLA-HANDLE.

SPECIFICATION forming part of Letters Patent No. 693,712, dated February 18, 1902.

Application filed March 26, 1900. Serial No, 10,237- (No model.)

To all, whom, it may concern.-

Be it known that I, FLETCHER C. HULL, a citizen of the United States, residing at Norwalk, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Detachable Handles forUmbrellas, Parasols, alking-Sticks, &c.; 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 detachable handles for umbrellas, parasols, canes, &c., and has for its object to provide means for readily attaching and detaching a handle, to sim plify the construction of the parts, reduce the cost of manufacture, to prevent lateral motion of the staff in the sleeve of the handle without binding, and to render the parts more durable.

The invent-ion consists of the construction, combination, and arrangement of parts substantially as hereinafter more particularly pointed out in the claims.

In the drawings, Figure 1 represents part of an umbrella rod or staff, walking-stick, or paraso], &c., and part of a handle, the latter being partly in section. Fig. 2 is a longitudinal sectional view showing the staff Withdrawn from the handle. Fig. 3 shows the staff detached from the sleeve and the sleeve detached from the handle, and Fig. 4 is a detached View of the spring.

In the drawings herewith, in which I have shown the preferred embodiment of my invention, 1 is the handle, having a longitudinal bore therein to receive a sleeve 2, the outer end of which projects a suitable distance beyond the end of the handle 1.

3 is a rivet which passes centrally through the sleey e at a suitable distance from the inner end thereof. The exposed end of the sleeve has a slot 4:, the walls of which are preferably cut away, as at 5.

6 designates the staff, stick, or rod of an umbrella or parasol or a walking-stick of such size in cross-section that it will slide into the sleeve 2 and is provided with a slot 7 to receive a boss 9 of a spring 8, said boss having its edges curved or chamfered for a purpose hereinafter described. The staff 6 has slots 10, the width of which is the same as the diameter of the rivet 3, which enters said slots when the rod is inserted into the sleeve 2, said rivet being located at such a pointin the sleeve as will give the desired bearing-surface between it and the staff to properly support the latter. The spring 8 9 is not required nor is it designed to prevent lateral motion of the staff within the sleeve, but is merely to prevent the handle from slipping off the staff.

The beveled or chamfered edges of the boss 9 will permit the sleeve to readily pass on or off of the staff when said boss is slightly depressed. The cut-away portion of the walls of the slot 4 facilitates the operation of removing the handle from the staff and replacing the same thereon.

The spring 8 maybe stamped out of spring metal, and its ends being free and equally distant from its boss 9 the latter will work freely through the slots 4 and 7 without bindin g therein, as would. be the case if the spring were supported at one end only or were rigidly secured at one end. The spring is inserted by pushing it into the staff until the boss comes opposite to the slot, when it springs into position and is there retained without any rivet or other fastening means whatever.

Heretofore it has been attempted to secure detachable handles against lateral motion by means of a spring; but such means have been found to be impracticable, as the spring must have some play in order to work freely, and this prevents the spring from holding the handle firmly without lateral motion. In my construction lateral motion is absolutely impossible.

I am aware that changes in the form and proportion of the parts herein shown and described may be made Without departing from the principle or sacrificing the advantages of my invention, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

Having thus described one embodiment of my invention and the best means now known to me for carrying the same into practical use, what I claim, and desire to secure by Letters Patent, is-- 1. The combination with a detachablehandle, having a sleeve and an attached rivet ar ranged within and transversely of said sleeve, of a stafi having slots in the end thereof adapted to engage with said rivet and means for the retention of said handle upon said stafi, substantially as shown and described.

2. A staflf having slots in the end thereof in combination with a detachable handle, a sleeve having an attached rivet arranged within and transversely of said sleeve and adapted to engage with the slots in the staif, substantially as shown and described.

3. A'stafli having slots in the end thereof, a spring having a boss projecting through the wall of the stafi in combination with a handle, a sleeve having a slot to receive said boss and a rivet arranged within and transversely of said boss to engage with the slots in the staff, substantially as shown and described.

4. The combination with a staff, a spring, a boss projecting through the wall of said staff and having beveled edges, of a detachable handle, a sleeve having a slot in theexposed end thereof and an attached rivet arranged therein,substantially as shown and described.

5. In an article, substantially such as herein described, a detachable handle, a sleeve, one end of which projects beyond the end of the handle and having a transverse rivet arranged interiorly of said sleeve and is slotted, the walls of which are cut away, in combina tion with a stafi and means for locking the staff to the sleeve, said sleeve adapted to partially inclose said staff, substantially as shown and described.

6. In an article substantially as herein described, the combination of a tubular staff or rod, the semi-elliptic or bowed spring, with its ends adapted to bear and freely slide on said stafi or rod, upon its inside, and having a central boss upon its convexity projecting through a slot in said staff or rod, and ahandle having a projecting sleeve provided with a slot adapted to be engaged by said boss, substantially as set forth.

7. In an article substantially as herein described, the combination of a tubular staif or rod, the semi-elliptic or bowed spring, with its ends adapted to bear and freely slide on said staff or rod, upon the inside, and having a central boss upon its convexity projecting through a slot in said staff or rod, and a handle having a projecting sleeve provided with a slot adapted to be engaged by said boss, said sleeve having an internal cross pin or rivetinterxnediately of its ends and said staff or rod having coincident notches at its lower end adapted to engage said cross pin or rivet, substantially as set forth.

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