SPECIFICATION forming part of Letters Patent No. 461,373, dated October 13,

Application filed July 27,1891. Serial No. 400,805. (No model.)

To @ZZ whom 7525 may concern,.-

Be it known that LADoLPHUs G. SNELL, a citizen of the United States, residing at New Haven, in the countyof New Haven and State of Connecticut, have invented a new and usen joint of two members loosely connected or linked together, the whole being manufactured and constructed in the manner hereinafter more fully described, and the appearance of the finished article being substantially that shown on the sheet of drawings, wherein Figure l is a side'elevation of a top-prop rod or support, an umbrella canopy, and my irnproved joint between these members. Fig. 2

isan enlarged front elevation of my improved joint with the yoke partly in section. Fig. 3 is a side elevation thereof with the ring Yand top-prop rod in section. Fig.- 4 is a detail of .a slight modification.

Referring to the said drawings, the letter P designates a rod adj ustably secured in and rising from a socket at the back of the carriage-body and extending thence forwardly over -said body. T is the top, which in the present case is an umbrella vor parasol, and .I is my improved joint, connecting the parasol to the rod in such manner that the former can be set at. any desired point on and at any angle to the latter, all as is well known in devices of this character.

The present invention contemplates the provision of anewjoint J, capable of the same functions as those heretofore used, as shown, but whose construction and whose process of manufacture differ to an extent from those of similar devices now on the market, the result being that a better article is produced at less cost, in shorter time, and by the saving of considerable labor. The j oint'which I thus referto comprises a bell B, preferably having a knob K at its upper end, through Vary according as the which extends an integral ring R. In the lower end of this bell is secured in any suitable manner-for instance, by a set-screw S', as shown.V

Y is a yoke, having an opening O transversely through i's body, closed atits lower end E, this opening loosely embracing the ring R and the rod P, and the entire yoke being of a single piece of casting.y

S is the usual set-screw, which passes downwardly through the yoke, and whose ti p bears the. rod with considerable force against the ring, and by this screw the angles of the yoke the staff of the top T on the rod and the ring inthe yoke can be adj usted.

In the inanufactureof this improved joint the bell, knob, and ring are first cast in a single piece. This casting is then laid in a flask provided with a inold for the yoke, the ring intersecting the mold at the point Where the opening C in the yoke-is to occur, and the ring at this point being surrounded by a sand core in the well-known manner 'of producing castings one of which is linked into or passed loosely through an opening in the other. The metal is then poured and the yoke is formed. From three hundred to four hundred pounds of the connected castings are then put into a barrel, which is afterward filled with water and sealed, and the whole is rotary,oscillatory, or vibratory motion, known as tumbling, which is continued for perhaps a week, and when the castings are taken from the barrel' they will be found to be smooth and nicely rounded, perhaps as well finished as though all parts of each had been ground on an emery-wheel. The castings are then tin ned with what is knownfto the trade as X. C. plate, or they may be nickeled or. japanned, as preferred. Before or after such finishing the yoke is bored longitudinally and threaded to receive the screw S, which is also finished in a manner to correspond with the balance, of the casting, as is the screw S if it be used. The complete jointis then ready to put on the -market,'and the size of the part-s or the dimension of the opening may, of course,

taste of the manufacturer may dictate or the diameter of the rod P may necessitate;- but these variations will be well understood by those interested in or familiar withthe art.

subjected to a ICO ywind. or by Instead of casting the yoke around the ring in the manner above described,l mayin some cases cast it or produce it in malleable iron in the form shown in Fig. i and then connect it with the ring by bending its arms together while hot and riveting, brazing, or otherwise connecting the lower ends of said arms within the ring, and practice and experience may teach that this is a less expensive manner to form the connected members than the above process. Izlowever, the resulting article possesses practically all the advantages of the one described above, and I suggest this modiied mode of its manufacture to show that I am not limited to the single process above set forth.

Referring to Fig. 2 it will be seen that the lower side ofthe opening through the yoke is cast on a curve C of greater radius than that of the inside of the ring R, and by reference to Fig. 8 it will be observed that the transverse curvature of the bottom of this opening is approximately the same as that of the ring in section. Vith this construction (which, it will be obvious, can be given the parts even when they are cast) the inside of the ring bears at only two points against the opening O through the yokenamely, at each end of the opening, as illustrated in Fig. l-while the sides of the ring bear against the sides of the opening at all points across the yoke, and the rod is pressed by the screw at only one point against the outer side of the ring. Thus it will seen that the ring is supported at two points as against a downward pressure at one point, which is always between those two, while all lateral motion of the ring within the yoke, and hence all liability of the parts to slip and allow the connection to become loose isf avoided by the sides of the ring at all times striking the sides of the yoke. This construction permits t-he screw to be set much tighter than if the yoke were open at its side, as is the case in a joint of this character which is now on the market. It gives three bearing-points on the ring, and it has no angles to mar the ring and presents no possibility of the latter slipping beneath the rod, even when the top is subjected to considerable strain, as in the the rough handling of the operator or of an infant.

What is claimed as new isl. The herein-described joint, thesamecomprising a bell having an integral ring, a yoke having a lateral opening integrally closed on all sides and through which said ring passes, and a screw passing downwardly through said yokeand into its opening,l as and for the purpose set forth.

2. The herein-described joint, the same comprising a bell, a knob, and a ring, all of a single casting, a set-screw through the side of the bell, a yoke having a lateral opening closed on all sides and through which said ring passes, this opening being also adapted for the reception of the prop-rod, and a screw passing through the yoke, with its point adapted to bear against said rod, as and for the purpose set forth.

3. In a joint of the character describechthe combination, with the bell and ring, of the yoke having a lateral opening closed on all sides and the longitudinal curvature of whose bottom is less than the corresponding curvature of the inner side of said ring which passes through said opening, and a screw passing downwardly through the yoke into its opening, as and for the purpose set forth.

4. In a joint of the character described, the combination, with the bell and ring, of the yoke having a lateral opening closed on all sides and through which said ring extends, the width of the opening at its lower end being substantially the same as the thickness of the ring, thus permitting the slipping but preventing the turning over of the ring,-and a' screw passing downwardly through the yoke into its opening, as and for the purpose set forth.

5. In a joint of the character described, the combination, with the bell and ring, of the Yoke having a lateral opening closed on all sides and through which said ring extends, the curvature of the bottom of said opening bein glongitudinally less than the corresponding curvature of the inner side of the ring and the width of said opening transversely the same as that of the ring, and a screw passing downwardly through the yoke into its opening, as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
