2 Claims. 1

This invention relates to an improved umbrella tip and tip holder and it is one object of the invention to provide a tip and a tip holder of such formation that when tips are applied to the tip holder of a tipping machine the tips will be firmly held with the thread receiving openings of the tips in vertical position and thus dispose the thread receiving openings directly under a needle in accurate alignment therewith and prevent a needle from being broken by striking portions of the tip during a sewing operation.

Another object of the invention is to provide a tip and a tip holder wherein the tip is formed with a bar or socket to receive the tip holder, the walls of the socket in the tip having flat faces and the tip holder having corresponding flat faces, thus making it necessary to turn the tip to a position in which its fiat surfaces are in faceto-face relation to the fiat faces of the tip holder in order to fit the tip upon the tip holder. It will thus be seen that the tip cannot be applied to the tip holder unless it is in predetermined relation thereto and that after it has been applied it cannot have turning movement about the tip holder to a position which would move the thread receiving opening of thetip out of a vertical position.

Another object of the invention is to provide a tip and a tip holder of such construction that the tips may be very easily applied to the tip holder by a thrusting movement and also easily withdrawn from the tip holder after the fabric of an umbrella or parasol has been sewed to the tips.

With this and other objects the invention consists of an improved construction and arrangement of parts illustrated in the accompanying drawings wherein:

Fig. l is a side elevation of the improved tip,

its thread receiving opening and its socket being Fig. "8 is a view partially in section and partially in elevation showing the tip applied to the tip holder and its thread receiving opening directly under a needle by means of which the fabric is to be sewed to the tip.

The improved tip may be formed of plastic or other suitable material. This tip which is indicated in general by the numeral has been shown with a spherical head 2 at its outer end and the shank or body portion of the t p has been shown circularly in cross-section, but it will be understood that the invention is not restricted to the specific shape of the tip. The body portion of the tip is bored from its inner end to form a socket 3 and upon referring to Fig. 6, it will be seen that instead of the bore or socket being circular in cross-section, it is formed with flat wall portions i disposed in opposed relation to each other. Therefore, the bore or socket is noncircular in cross-section and when the tip is appl ed to a holder of similar shape in cross-section the tip will be prevented from having turning movement on the holder. Intermediate its head 2 and the inner end of the socket 3 the tip is formed with a diametrically extending opening 5 through which thread is passed to secure the tip to the fabric of an umbrella or parasol. The holder 6 to which the improved tip is applied during a sewing operation, is used in connection with a tipping machine of conventional form and its shank I is thrust into a socket 8 of the portion 9 of the tipping machine and a set screw [0 then tightened so that it has gripping engagement with the shank I and securely holds the tip holder firmly seated in the socket 8 of the shoulder ll of the tip holder in abutting engagement with the confronting face of the said portion 9 of the tipping machine.

The tip holders of conventional formation are circular in cross-section and the sockets formed in tips to be applied thereto are also circular in cross-section. Therefore, care must be exercised when applying tips, as it is important that the thread receiving openings be disposed vertically in exact alignment with a needle. The improved tip holder has opposite side portions reducedin thickness from opposite sides, thus forming flat side faces l2. This causes the forward portion of the tip holder to conform in cross-section to the cross-sectional shape of the socket 3, it being understood that this portion of the tip holder is of such dimensions in cross-section that it willfit snugly into the socket 3. Therefore, when a tip of the improved construction is applied to a tip holder of the improved construction and turning adjustments made to dispose the thread receiving opening 5 directly under the needle l3 in alignment therewith and the set screw I then tightened, the improved tip and all other types applied to the tip holder will be so mounted that during a sewing operation the needle will pass through the thread receiving opening and the thread [4 applied to secure the tips to the fabric l5 of an umbrella or parasol, and there will be no danger of the needle being broken as it cannot strike the walls of the thread receiving opening or other portions of the tip.

While it has been stated that the socket of the improved tip and the forward portion of the tip holder which are formed with two fiat surfaces in opposed relation to each other, it will be understood that the invention is not limited to the specific number of fiat surfaces and that any number desired which will form a socket and a tip holder of non-circular cross-sectional shape, may be provided. After a tip has been applied to the improved tip holder and adjustments made to dispose the thread receiving opening in accurate alignment with the needle, the tip holder will be firmly held against movement out of a set position and additional tip holders may then be quickly applied and each will be in its proper position.

From the foregoin description of the construction of my improved device, the operation thereof and the method of assembly will be readily understood, and it will be seen that I have provided a comparatively simple, inexpensive and efficient means for carrying out the various objects of the invention.

While I have particularly described the elements best adapted to perform the functions set forth, it is apparent that various changes in form, proportion and in the minor details of construction may be resorted to, without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described the invention, what is claimed is:

1. An umbrella tip formed with a socket leading from its rear end longitudinally thereof and having opposed wall portions formed with fiat surfaces and other wall portions between the flat Wall portions arcuate transversely, the-re being a through the tip diametrically thereof in front of the socket; and a holder for temporarily supporting the tip in a horizontal position with its threadreceivin opening disposed vertically in position for passage of a needle through the opening, said holder having its forward portion reduced in diameter from opposite sides and forming opposed flat faces for the holder, faces of the holder between its flat faces being transversely arcuate, the shape of the holder in cross section thereby conforming to the transverse shape of the socket and thereby adapting the tip to be thrust upon the holder only when in a position disposing its flat wall portions in face to face engagement with the flat side faces of the holder to prevent turning movement of the tip relative to the holder and retain the thread-receiving opening in a vertioal needle-receiving position.

2. An umbrella tip formed with a longitudinally extending socket leading from its rear end and terminating in rearwardly spaced relation to a thread-receiving opening formed transversely through the tip; and a holder having a portion fitting into the socket for temporarily supporting the tip horizontally with the thread-receiving opening in a vertical position for passage of a vertically movable thread-carrying needle through the opening, said socket and the portion of the holder fitting therein being of such configuration in transverse cross section that its transverse and vertical dimensions are of different lengths and thereby prevent turning of the tip about the holder and allow the tip to be fitted upon the holder only when the thread-receiving opening of the tip is in the vertical needle-receiving position.
