IMPROVEMENT IN cassettes,

{the snout nftrnhtt in that 'itittts hunt mu mating part at the smut;

TO ALL WHOM IT MAY CONCERN:

Be it known that I, Gouvrou G. GnIswoLD, of the city, county, and State of- New York, have invented certain new and useful Improvements in Umbrellas; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to the construction of the notch or crown-piece and runner to be used in umbrellas; the devices which secure the ribsanil stretchers to or in the notchor crown-piece.and runner respectively; tc the spring-catch which fastens the umbrella either open or shut; and to the construction of the inner ends oi the ribs and stretehers, to adapt them tobe used with the notch .or crown-piece and runner as improved.

My object is to produce an umbrella cheaply, which shall be neat and durable, and the notch or crownpiece and runner of which shall be so constructed and arranged with reference to the ribs, and stretehers that a rib or a stretcher may easily be removed when broken and its place supplied by another.

My invention consists-- First,'of a notch or crown-piece, made with an annular groove in the inside of one end ot'it, and slots cut through into'said groove, through which the ends of the ribs pass, which ends are made T-shapcd, so as to beanagainstihemllaofi the. sa d groove at each side of the said slot, and thus held the saidribs from drawing out radially, and in the combination therewith of an annular piece of rubber, or other flexible yielding substance, which is plaeed between the inner edge of the wall surrounding the said annular groove and the tube or staff of the umbrella, and partly within the said groove, to secure the ends ofthe said ribs from coming out, sub stantially as hereinafter set forth. That portion ofthe runner which receives the ends of the stretchers is made similar to the notch or crown-piece, as abbve described.

Second, in the combination with the notch or crown-piece, made as above setforth, of a metal or leather. ring, having a. notch or crown-piece cut into it, or a. piece or portion removed from it, so that the said notch or crown piece may be moved opposite each or either of the slots in the wall of the said annular groove, 'so as to admit of the insertion or withdrawal of one or more of the ribs when desired, for repairs, &c., the said metal "ring being set within the groove, or against the opening, and serving to close the opening between the walls of the annular, groove and the tube or staff, substantially as hereinafter more fully set forth Third, in the combination with the runner, made as above set forth, of suitable spring-catches, which pass down through the walls of the annular groove in the said runner, and are supported in slots made therein, and which. are held down in position by the rubber ring within the runner, substantially as hereinafter more fully set forth Figure 3 is a section showing the parts-above the line x :e, fig. 1.

Figure 4 is a detail view of ,a tube or stnfi', with a notch or crown-piece having a metal ring in it, and a runner with spring-catches, difif'ernt in form from those shown in fig. 1.

Figure 5 is an underside view ofthe notch or crown-pieccseen in fig. 4.

Figure 6 is a topview oi the runner seen in fig. 4.

Figures .7, 8, 9, and 10 show in detail different forms which may be given to the ends of the ribs and stretehcrs, to fit them for the notch or crown-piece and runner.

Figure 11 is a side elevation in detail of one of the spring-catches seen in fig. 1.

Figure 12 is another form or modification of the notch or crown-piece with metal ring.

Figure 13 is a radialsection of a runner in which a metal ring is used with the slotted groove.

A is the staff of the umbrella; B B are the ribs; C C are the stretchers; D, the notch or crown-piece, and E the runner. F is a sleeve, having a groove and shoulder in its surface for the spring catches G to hook into when the umbrella is raised or spread, andH is a. similar slecvc, for the said catches to hook under when, the umbrella is closed. I is a rubber ring, which. serves in the runner to hold the ends'of the stretchers from slipping out of their seats, and also to spring the catches G G intotheir places, and to hold them there. J is a ring of rubber, or other sufliciently yielding substance, which being thrust into the opening betwcenthe secafterwards returned to its original position.

tions at a of the walls of the groove in the notch or crown-piece D, and the stat? A, prevents the ribs from work ing out,while it may be either compressed or removed sufliciently to permit of the withdrawing of a rib or the inserting of another in place of the one rcmovedfor repairs, 8:0.

The spring-catches G G are made in the form shown in figs. 1 and 11, having books at each end, to hook into the sleeves above and below, for the purpose of fastening the umbrella either open or shut, as may be desired. Near their upper ends they are both made semi-cylindrical in form for a short distance, just at that portion which .comes under the rubber spring I, (as seen at b, fig. 11,) for the purpose of furnishing a suitable bearing for the spring I, and to prevent itlfr'om rubbing'against the shaft as the runner is moved up or down. The spring-catches G G are kept from slipping up or down by a groove on the inner side of each, which fits snugly over a projecting fillet or bead on the runner, as seen at c, fig. 1, and '01, fig. 4. This fillet also serves as a fulcrum for the'spring-ca-tches G G. I i

The ordinary form of springcatches may be used, and therubbcr ring I dispensed with, using instead thereof a. metal or other suitable ring, as seen in fig. 13, in which K is the runner, and L. the ring,.which has a notch or crown-piece, 7c, in one side of it. Whenever the notched ring g or L is used, it may have one or more notches in it, but I prefer to have but one, as that'is sufficient.

In order to remove a broken or damaged rib or stretcher from the notch or crown-piece or runner shown in figs. 1, 2, and 3, or from the runner shown in fig. 4, the centre ring, I or J, as the case may be, is forced up out of the groove far enough to admit of the insertion or withdrawal of the rib or stretcher, and the ring is In figs. 4, 5, 12, and 13-thc Oe11tre")'illg,g or L, of the notch or-crown-piece or runner is made of metal, leather, or other suitable material, and a slot or notch or crown-piece, e or k, is out into or through it. By bringing this slot 0 oppositeone of the slotsin thcnotch or crown-pieceD, or runner E or K, a. rib may ehsil be inserted or withdrawn, and'by turning the ring'around until the notch or'crown-piece e or 7: is opposite one of the leaves which compose the wall of the annular groove in the notch or crown-piece or runner, the ribs are fastened into position. The ring may be secured from turning by dotting it at its junction with the leaves f with a punch, or it may be secured in any other way deemed best. The notch or crown-picce or runner may also be extended downward or upward, and the metal or other ringput on'below, as seen in fig 12, a slotbeing made in the ring as before, and the ring, when adjusted, and the ribs in, secured inn similar manner from turning around, so-as torelease the ribs. I

In fig. 4, the spring-catches G G are shown in asomewhat modified form. They have hooks on the upper ends only, and these hooks shut or catch into holes in the staff or tube, though they could be made to catchinto a groove in a sleeve, as in fig. 1, I prefer, however, to use the catch shown in fig. 1, as the sleeve strengthout; instead of weakens the stali', and the groove or shoulder extending entirely around the sleeve, there can be no trouble or delay in making the hooks catch.

Sutfieient shoulders, or projectionsmay be madein the ends of'the ribs and strctchers in a variety of ways, some of which are shown. It and i show a globe or sphere struck up on the end of the rib or stretcher, and j a. cylinder, whose axis is perpendicular ,to the str'ctcher or rib. '-Tlicse, especialy the sphere, I consider the best.

Figs. 7 and 10 show other forms which may be used.

.Having thus fully described my invention, I claim- 1. The combination, with a notch or crown-piece or runner for umbrellas or pnrasols, having an annular groove and radial slots in it for the ends of the ribsor stretchers to work in, of a ring of rubber, or other suitable elastic yielding material, forfastening said ribs or stretchers in said groove, while'at the same time one or more of the said ribs or strete'hers may readily be removed for repairs, substantially as setforth.

2; The combination, with a notch or crown-picce or runner of an umbrella or Parasol, having an annular groove and radial slots in it for the ends of the ribs or. stretcher-s to work in, of a metal, leather, or othersuitable ring, for fastening said ribs or stretchers in said groove, said ring having one or more slots in its side, to permit of the introduction or withdrawal of one or more of the ribs or'stretchers, substantially as set forth.

3. The combination, with the runner Id, of the spring-catches G G, operated in part or wholly by the Indiarubber or other elastic ring I, substantially as set forth.
