SECURING NOTGHES TO STIQKS 0F UMBRELLAS AND PABASOLS.

UNITED STATES PATENT OFFICE.
JOHN B. RIEI-IL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO AMERICAN SPECIALTY MANUFACTURING COMPANY, OF DOVER, DELAWARE, A CORPORATION OF DELAWARE.
Specification of Letters Patent.
Patented Nov. 30, 1909.
Application filed April 16, 1908. Serial No. 427,445.
To all whom it may concern:
Be it known that I, JOHN B. RIEHL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Securing Notches to Sticks of Umbrellas and Parasols, of which the following is a specification.
The objects of my invention are to attach a notch to the metallic stick of an umbrella or parasol more securely than by the use of the usual transverse pin or rivet; to efiect such attachment without weakening either the notch or stick by the formation of openings therein, and to perform the operation more economically and expeditiously than when the transverse pin or rivet is used. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which- Figure l is a side elevation, on an enlarged scale, of part of a metal umbrella stick having a notch secured thereto in accordance with my invention; Fig. 2 is a longitudinal section of the same; Fig. 3 is a sectional plan view on the line a-a, Fig. l, and Figs. 4L and 5 are views illustrating the manner in which the securing of the notch to the stick is effected.
In the drawing, 1 represents part of the tubular metallic stick of an umbrella or parasol, and 2 the notch to which the upper ends of the ribs are pivotally attached, this notch being, in the present instance, made in accordance with my Letters Patent No. 837,731, dated December 4:, 1906, although my present invention is not limited to notches of this character but may be applied with equally good results to any notch having a tubular neck or other portion in which indentations can be formed.
In the present instance, the neck 3 extends above that portion of the notch to which the upper ends of the ribs are attached and said neck fits snugly to the stick 1, to which it is securely confined, both as regards longitudinal and rotative movement, by one or more indentations 4, a plurality of such indentations, equidistantly disposed around the neck, being preferably employed and four of these indentations being shown in the drawing. The indentations are formed by driving inwardly the metal of which the neck is composed, preferably to such an eX- tent as to form lateral offsets therein, and thus slightly indent or offset the metal of the stick, as shown in Figs. 2 and 3, although, in most cases, a sufliciently secure attachment may be effected even if the metal of the stick is not thus indented, the indentation of the stick being for additional security.
In order to secure the notch to the stick in this manner, I employ dies, each having a clamping member 5 and an indenting memher 6, suitably guided on said clamping member, the latter being so constructed as to bear upon the neck 3 of the notch on each side of, and preferably, also, above the point at which the indentation is to be formed by the member 6, whereby all portions of the neck adjacent to that which is to be indented can be firmly clamped to the stick, as shown in Fig. 4:, before the indenting die is projected, as shown in Fig. 5, thereby limiting the area of displacement of the metal and insuring for the indentation a sharply defined outline with such shoulders as will effectually lock the notch to the stick against movement in any direction.
Not only is a more secure attachment of the notch to the stick thus provided than when the usual transverse pin or rivet is employed, but there is no weakening of the notch or stick by the formation of openings therein for the reception of such transverse pin or rivet, and the operation can be more economically and expeditiously performed than when the notch and stick have first to be drilled and the pin or rivet afterward inserted and secured in place.
I am aware that it has been proposed to secure an umbrella notch to a Wooden stick by driving a pointed instrument through the metal sleeve of the notch so as to form an inwardly projecting bur which bites into the wood of which the stick is composed, but this involves a rupture of the metal of the notch and a corresponding weakening of the same, together with a weakening of the stick due to the mutilation of the .wood of which the same is composed.
In carrying out my invention neither the metal of the notch nor the metal of the stick is broken, and there is no impairment of the strength of either notch or stick by reason of the formation therein of the indentations whereby these two members are locked together.
I claim:
1. The combination of a metallic umbrella stick of closed tubular form with a notch secured thereto by interlocking and unbroken indentations in the notch and stick;
2. The combination of a metallic umbrella stick of closed tubular form with a notch secured thereto by a series of equidistantly disposed, interlocking and unbroken indentations in the notch and stick.
3. The mode herein described of securing a notch to a metal umbrella stick of closed tubular form, said mode consisting in first clamping the notch to the stick at various JOHN B. RIEHL.
