Patented Nov. 2, l196e.

Application led April 12, 1909. Serial No. 489,410.

To all whom 'Lt 'may concern:

Be it known that I, ELM-ER C. BEEGHER, a citizen of the United States, residing at Norwalk, in the -county of Huron and Statev ofOhio, have invented a new and useful Umbrella-F rame, of which the following is a specification. y l

The object of the invention is in .a'novel and practical manner, to dispense with the employment of wires in holding the ribs and spreaders assembled with the notch and the runner, and further to facilitate the replacement of a damaged o1' worthless rib or spreader by a new one, and this without the employment of special-tools for the purpose.

Vith the above and other objects in view, as will appear asthenature of the invention is better understood, the same' consists in the novel construction and combination of parts of a notch, runner, rib and spreader for an umbrella, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts:-Figure`1 is a view in side elevation -of an umbrella frame constructed in accordance with the present invention,the raised position ofthe runner and the ribs and spreaders being shown in full lines, and their lowered position in dotted lines. Fig.

2 is a vertical longitudinal sectional view, l

on an enlarged scale, through the notch and a portion of the stati' vor rod. Fig. 3 is a similar view through the runner.v Fig. 4 is a horizontal sectional view, taken on the line 1l-4, Fig. 2 and looking in the direction of the arrow thereon. Fig. 5 is a erspective diied form of rib or spreader.' Fig. 6 is a vertical, longitudinal section showing in a modied form, means for holding the notch 2 in contact with the cap 11.

The invention includes a notch, shown in. Fig. 2,' and arunner, shown lin FigfB, the same being designated generally as staffh inclosing members and ribs 4 and'spreaders 5, the same being designated' generally as supporting members The stad 1 may be of any preferred construction, and. in this instance is shown as being of the tubular metall type in common use. Slidably mounted upon the upper lportion of the stai is a notch .2 which is provided with regularly disposed slots 3 to receive the inner ends of theribs 4 which, as

well as the spreadcrs- 5, are of the semitubular type, as'clearly shown in-.Fig 5,

addition to the shoulder 9, which is common to 'such attachments and that engages with ltheupper wall of the slot 7 to hold the notch m the position shown in Fig. 1, with a second'shoulder 10, the function of which will appear farther on. To prevent` upward movement of the notch and also to cause its upper end to hold the ribs against detach ment and toinsure their proper operation, a cap or cover 1l is provided which is circumferentially commensurate with the notch, and-is providedwith la tubular extension 12 through which, and through 'the staff, passes a pin or rivet 13, the ends of which are upset, as clearly shown in Fig. 2. The upper The notch is portion of the notch is formed with twoi . coaxial chambers 14 and 15, the difference between the diameters of which forms a circumferentialshoulder, t-he edge 16 of which constitutes a fulcrum or bearing .for the heads 17 of the ribs. These heads are formed by transversely flattening one end of each rib, as shown at 18 and then bending' the end of this flattenedportion vat substan,

tially right angles to its length, as shown in By the provision of the circumferential fulcrum, the ribs and spreaders are caused to work easily and without danger of contacting or binding whenthe umbrella is openedl or closed. As will be observed by reference to Fig. 2, the upper corners of the heads .17 bear against the under face of the cap 11 when the .ribs are raised or lowered, and this will prevent any looseness of the ribs that would be objectionable. Furthermore the two chambers 14 and l5 are of such .size as to permit perfect freedom of movement of the ribs but without any unnecessary play. As willbe obvious, the slots 3 must be extended into the ychamber 15 in order -to permit the proper arcuate movement of the; ribs.

ico

Referring now to the latch 8, the function i of the shoulder l0 will be explained. As above stated, the shoulder 9 operates to lhold' the notch in contact with the cap, and

latch 23 that engages with the under side of.

sufficient distance downward vupon the stali to permit a rib or ribs to be removed` with@ out disturbing the others. This limitation in the movement of the notch is important,

inasmuch as4 if the shoulder 10 were not present, the notch 4might be moved downward such a distance that all of the ribs would become detached, and in an attem t to vreplace them, the person repairing t e umbrella might get 'a rib in the wrong slot,"

and the result would be that when the umbrella was raised, there would be a binding action between the ribs and the slots whichmight result in brealring one or more ribs.

The runner shown in detail in Fig. 3 is of i the same general construction as the notch, and therefore the same reference characters .are employed m de signatin like parts. There 1s, however, an `additional element -employed, such as is common withv runners of ordinary construction, andthat is a sleeve '2O to which the cap 11 is rigidly securedby rivets 21,` This sleeve is provided with a slot through which projects an vordinary the vtubular extension l2'of the cap, and thus holds the runner in raised osition, as shown in Fig'. 1. The spreader 5 1s provided with a head 17 of thesame construction the rib and.' operates in exactly the samel manner. 4

7 In order to permit the head 19 of the` runner, whichis slidably mounted upon the member 20, to be moved away from the cap or closure 11, the member 20 is provided with a spring tongue 22, formed by incising the metal for this purpose and which normall engages'with the upper edge of the tubu ar extension 6 of the head. When it is `desired to replace a damaged or broken spreader by a new one, thev tongue 22 is forced inward a4 sufficient distance to clear1 the extension 6, whereupon the runner may be moved upward, and thus allow the c spreader to be removed.

y Generally, a single head 17 will answer all practical purposes, but 'if preferred, andA as shown in Fig, 5, the head 24 may be T-shaped. v

` From the foregoing description, it will be seen that while the improvements herein defined are simple in character, they will be thoroughly elcient fory the lpurposes designed and will coact in the production-of 'an efficient, durable, and highly effective form ont umbrellaV frame.

l it is obvious that, as shown in Fig. 6, the

latch 8 Vmaybe dispensed with, the notch e 6'5" being held in place by a pin 25 passed transversely through the tubular extension 6 of the notch and the staff 1, into alined apertures therein, and having its end overturnedk to holdit in place. T claim 1,. In an umbrella, a statt-inclosing mem-l ber having coaxial,I communicating chambers of .different diameters denmg between member; and a supporting member having a head to engage the fulcrum.

2. -In .an umbrella, a staff-inclosing member having coaxial communicating chambers 4of diderent diameters defining between them a circumscribing fulcrum, the member being lthem a circumscribing fulcrum within the rovided with upright notches intersecting the walls of vthe chamberand the fulcrum;

and supporting members having laterally inclined heads to engage the ulcrum andy being mounted in -the notches. .v

Tn testimony that I claim the foregoing as my own, I have hereto atli- Xedmy signature in the presence of twowitnesses.
