Specification of Letters Patent.

Patented Oct. 24, 1905.

Application iled November 16, 1904. Serial No. 232,967.

vT9 uf/Z/ 'wi/1,0177, it mfr/y concern:

Be it known that l', JOHN V. SYBRANDT, a citizen of the United States, and a resident of Springdale, in the county of Boulder and State of Colorado, have invented a new and Improved Umbrella, of which the following' is a full, clear, and exact description.

My invention relates to umbrellas and similar articles, and is capable of application to canopies, tents, and the like.

The chief object of the invention is to provide means whereby an article of the class mentioned can be made of any desired form without interfering with its capability of bcing' folded.

Other objects are to provide for mounting such an article at any desired ang'le and to apply curtains thereto.

Further objects of the invention will appear in the course of the subjoined description.

Reference is to be had to the accompanying d rawing's, forming' a part of this specification, in which similar characters of reference indicate corresponding' parts in all the ligurcs.

Figure l is a side elevation of a carriage,

showing one form of my invention applied thereto. Fig'. 2 is a bottom plan view of the umbrella shown in Fig. l. Fig. 3 is a side elevation, on an enlarged scale, of a portion of the framework of an umbrella constructed on the same principle. Fig. 4 is a longitudinal sectional view, on an enlarged scale, of the same. Fig'. 5 is a sectional view on the line 5 5 of Fig. l on an enlarged scale. Fig. 6 is a rear elevation of a vehicle, showing the um brella-stick and means for securing it in different positions. Fig. 7 is a sectional view, on an enlarged scale, showing' the adjusting' means illustrated in Fig. 6; and Fig. 8 is a fragmentary view showing a detail.

I accomplish the first object mentioned above by making the ribs of dili'erent lengths, according to the desired shape of the canopy.

It is to be understood that when the word canopy7 is used in this specification it signi- `lies other articles of a similar nature-as, for example, an umbrella or a tenthand that the invention is capable of application to these other devices.

Fig. 1 represents a vehicle c. An umbrella is supported therein bya stick c. The umbrella, as shown in Fig. 2, is rectangular in `form and is provided with three series of ribs d, (,Z, and d" of different lengths. These ribs are all pivotal] y attached to the crown a, which is secured to the stick in the usual or any desired manner. By providing ribs of different lengths it will be understood that umbrellas or other articles of the classes mentioned above can be made of any desired shape. They can project out a distance on one side, so as to cover several seats in the vehicle, or they can be made elliptical, and when used for tents it will be obvious that the shapes which they may assume will be unlimited. Pivotally connected with the ribs are three series of spreaders j', j", f2. Each set of spreaders is connected with an independent slide, the three slides thus provided being' designated g, g', and g, respectively, as shown in Fig. 3. The ribs of the longest set Z are connected, by means of their respective spreaders, with the lowest one of these slides g. The shorter sets of ribs are connected,by means of their respective spreaders, with the slides g' and g2, which are located above the VBret-mentioned slide g. The slides f/ and y are freely movable upon the stick. The slide g, however, is provided with a perforation y: and with a catch g of the ordinaryor any desired kind. The stick c is also provided with a perforation or indentation c, with which the end of the catch engages. It will be readily understood that when it is desired to raise the umbrella the slide r/is forced upwardly until it picks up the slides f7 and g and carries them with it to their uppermost point, at which time the end of the catch ,r/l is opposite the indentation c and the catch is then forced into the indentation by its spring To lower the umbrella, the operation will be reversed in an obvious manner.

In order that the umbrella may be placed at any desired height with respect to the stick, the latter is made in two parts. The upper part c, which has been referred to above, is preferably in the form of a tube, and the lower part i may be tubular or solid, but is small enough to enter the tube c. This forms a telescopic joint, and rotation of the um brella is prevented by means of a groove It in the member /t and an internal projection c2 on the tubular portion of the stick. In order to secure the part c with respect to the part 71. when they are once adjusted to the proper position, a nut/ll is provided upon'the lower end of the tube c. This nut is threaded at t" for only a portion of its length, so that it can be screwed up and down upon the tube. A. key j is mounted between the nut and the tube and is provided with a roughened or serrated face y", passing through an opening c3 IOO in the tube. It will be readily observed that upon tightening the nut by screwing it upwardly upon the tube it will bind the inclined rear surface of this key so as to force its roughened face j through the opening c3 and into contact with the part 7i of the stick. This nut can be so tightened as to cause this contact to be maintained under great pressure and to prevent the sliding of one portion of the stick upon the other.

In order to adjust the position of the stick with respect to the vehicle, a rod k, as shown in Figs. 6 and 7, is provided at any convenient point-las, for example, upon the back of the seat. A bracket [is preferably placed upon this rod and secured to the rod" by means of a thumb-screw l. The stick c passes through a perforation in the bracket. On the bottom of the stick is a projection It, which enters an opening in the floor of the vehicle or in any other support, providing' a pivotal connection between the stick and the support.

In order that the stick may swing upon this pivot, the rod 7L' is preferably made in the form of an arc of a circle, having this pivot as its center. On the inside of the umbrella a chain m' is provided and is connected with the several ribs just within the outer edge of the cover. This chain assists in holding' the ribs and preventing them from being torn from each other in a high wind, and by being located at this point the fringe can be hung thereon to produce a neater appearance, and the fringe will be protected from the drippings from the edge of the umbrella.

Another important feature of my invention consists in a curtain fa, which is removably connected with the umbrella at any desired point. For example, it may be applied to the rear end or to a half of one side, as shown in Fig. l. This curtain is made removable and is connected to the umbrella by means of hooks n. These hooks can conveniently be attached to the chain at any desired point and without the necessity of hunting for an eye.

fhile I have illustrated and described one embodiment of my invention, it is to be understood that it is not strictly limited thereto, but that it may be constructed in many other forms and that many modifications may be made in the form shown. Also, it may be applied to all kinds of canopies and tents and other articles of a similar nature. It will be observed that when this principle is employed articles of this character can be made of any desired form without interfering with their capability of being folded into a compact position on the stick, also that an improved stick capable of providing any desired adjustment in the height of the top has been disclosed, as well as an improved manner of mounting the stick upon a vehicle or any other desired support, and it will also be understood that more or less than three slides may be employed, if found desirable.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An umbrella, comprising a pair of telescoping' elements longitudinally adjustable with respect to each other, the outer one having a perforation, a longitudinal tongue-andgroove connection between said elements, and a key secured to the outer element and provided with a roughened face adapted to project through the perforation of the outer element into engagement with the inner one.

2. An umbrella comprising a pair of telescoping elements longitudinally adjustable with respect to each other, the outer one having a perforation, a longitudinal tongue-andgroove connection between said elements, a key secured to the outer element and provided with a Toughened' face adapted to project through the perforation of the outer element into engagement with the inner one, and means for securing said key to the outer element.

3. An umbrella comprising a pair of elements longitudinally adjustable with respect to each other, the outer one having a perforation, a nut having a plane internal surface and a screw threaded internal surface having screw-threaded engagement with the outer of said elements, and a key having an inclined rear face adapted to be secured between the plane surface of said nut and the outer element and provided with means for engaging with the inner element through said perforation.

A. An umbrella comprising a pair of telescoping elements longitudinally adjustable with respect to each other, the outer one having a perforation, a longitudinal tongue-andgroove connection between said elements, a nut having a plane internal surface and a screw-threaded internal surface, and having screw-threaded engagement with the outer of said elements, and a key having an inclined rear face adapted to be secured between said nut and the outer element and provided with a roughened face adapted to project through the perforation of the outer element into engagement with the inner one.

' 5. A rectangular foldable canopy or umbrella provided with a chain secured to the ribs near their outer ends, in combination with a curtain provided with hooks and removably secured to said chain.

6. An umbrella, comprising a pair of telescoping elements longitudinally adjustable with respect to each other, the outer one having a perforation, a longitudinal tongue-andgroove connection between said elements, a nut having a plane internal surface and a screw-threaded internal surface and having screw-threaded engagement with the outer of said elements, a key having an inclined rear face adapted to be secured between said nut and the outer element and provided with a roughened face adapted to project through IOO IIO
