Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed September 4, 1915. Serial No. 48,961.

To aZZ whom it may concern:

Be it known that I, HnnMAN E. SCHULTZ, Jr., a citizen of the United States of Amen ica, residing in the city of St. Louis and State of Missouri, have invented a certain new and usefullm'provement in Umbrellas,

. of which the following is a full, clear, and

exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to improvements in umbrellas, one of the. objects to produce a strong, simple and positive locking means for securing an umbrella in its open position. The novel combination of elements is particularly adapted to form part of a large wagon umbrella having an angular socket member which receives both the central stem of the umbrella and the bracket whereby the umbrella is supported. I preferably simplify the locking means by interlocking the central stem with the supporting bracket, and these parts are preferably retained in interlocking engagement. through the medium of the means for securing the umbrella to the supporting bracket. This simple means for locking an umbrella in its open position, adds very little to the cost of the umbrella, and owing to its strength, the locking device in well adapted to withstand the severe shocks to which a'wagon umbrella is subjected.

Figure I. is a side elevation, partly in section, showing the central portion of an umbrella frame and the means for locking the umbrella in its open position. Fig. 11. is a section taken on line IL-II, Fig. I. Fig. 111. is a section on line III-III, Fig. I. Fig. IV. is a detail view of the lower portion of the central stem of the umbrella. Fig. V. is a detail view showing a portion of the angular socket member and a portion of the supporting arm.

1 designates ribs pivoted to an upper notch-ring E2, the latter being fixed to a central stem or staff 3. An angular socket member A has a vertical arm 5 adapted to receive the lower end of. the central stem 3, and a horizontal arm 6 which is slidably fitted to the tubular arm 7 of a supporting bracket. All of the elements of the umbrella are supported by the tubular bracket arm 7. The lower notch-ring 8 is rigidly secured to the vertical arm 5 of the socket member A, and

the stretchers 9 are pivoted to said notchrmg. The central stem 3 is slidably fitted to the vertical arm 5 of the socket member, and when the umbrella structure occupies its open position, the stem occupies the position shown in Fig. I. In closing the umbrella, the stem 8 is withdrawn from the socket member A- V 10 designates a yieldable latch member, in the form of a spring, secured to the central stein?) and adapted to extend through an open ng inthe socket member A, so as to y eldlngly secure the'umbrella structure in its open position.

The umbrella frame, including the ribs 1, stretchers 9 and central stem 3, is secured to the angular socket member A, the latter being detachably secured to the tubular bracket arm 7. The socket member A is slidably mounted on arm 7 and provided with notches 12 adapted to receive a pin 13 which projects from arm 7 A threaded sleeve 14, rotatably fitted to the bracket arm 7, is screwed onto a threaded end of the angular socket member.

It will be noted that the socket member A is interlocked with the bracket arm 7 through the medium of pin 13, and that the extended endsof said pin are held in the notches 12 by means of screw threaded sleeve 14:. The sleeve has a shoulder 15 which engages the pin 13 when the socket member is locked onto the bracket arm 7.

The lower end portion of the central stem 3' is preferably pressed to form a recess 16 and a lug 17, and when the umbrella is open, an end portion of the tubular bracket arm 7 lies in the recess, and the lug 17 lies in said bracket arm. The umbrella structure is thus securely locked in its open position, the central stem 8 being securely interlocked with the bracket arm 7 so that the stem cannot be accidentally withdrawn from the socket member. The threaded sleeve 1 1 retains the central stem in interlocking engagement with the bracket arm 7.

In opening the umbrella the central stem is forced into the socket member and automatically latched by the yieldable latch delatch device 10, the socket member A is moved on the bracket arm 7 to interlock said arm Withthe central stem 3, thereby posi- V tivelysecuring said stem-in the socket mem ber. Thereafter, the threaded sleeve 1ft 1s tightened to secure the umbrella to.-the bracket arm 7, and to retain said bracket arm in interlocking engagement with the central stei the said central stem being recessed toreceive an end portion of said tubular bracket arm when the umbrella structure occupies its open positiornand meansffor securing said angular socket member to sald tubular arm so as to retain the end portion of said tubular arm in saidrecesa thereby positively locking the umbrella structure-in its open positlon. r

2. An umbrella having a' central stem, an-

lug adapted to lie Within an endportion of .said'tubular arm when the umbrella structure occupies its open positiomand means 'forsecuring said angular socket member to.

said tubular arm so as to retain said lug in said tubular arm. a f
