This invention relates to a. suction nozzle for vacuum cleaners or the like and more particularly to a nozzle which is adjustable in all directions in I accordance with the surface to be cleaned.
An object of the invention is to provide a suction nozzle which is readily adjustable for the purpose above indicated. v
Another object is to provide a nozzle having a ball'and socket connection to the suction conduit it and which is movable through a substantial angle.
Another object is to provide a ball and socket connection for a suction nozzle in which the arc of contact between the ball and socket is reduced to a minimum.
Another object isto provide a device of the above type which can be readily assembled and disassembled.
Various other objects and advantages will be apparent as the nature of the invention is more ht fully disclosed.
Although the novel features which are believed to-be characteristic of this invention are pointed out more particularly in the claims appended hereto, the invention will be better understood by referring to the following description taken in connection with the accompanying drawing in which certain embodiments thereof have been set forth for purposes of illustration.
In the drawing: 30 I Fig. 1 is a plan view of a suction nozzle and conduit constructed in accordance with the present. invention showing the nozzle applied to a surface to be cleaned;
Fig. 2 is a vertical section through the nozzle 35 and the adjacent part of the suction conduit showing the ball and socket connection.
Fig. 3 is a transverse section taken along the line tt of Fig. 2;
Fig. l is a detail view showing one means for connecting the guide member to the supporting l Fig. 5 is a longitudinal section similar to Fig. 2 showing a different embodiment of the invention; and

tit
Referring to the drawing more in detail, Fig. 1
zle enters the corner of the frame for cleaning purposes. It is to be understood that the edges of the suction nozzle maybe provided with a suitable brush 23 as shown in Fig. 2 to facilitate cleaning.
The suction nozzle Ill is attached to the connector it by means of a ball and socket joint which comprises a ball It formed on the connector II and'a socket i5 formed in the housing of the suction nozzle ill.
The ball [4 and socket i5 are so arranged that the socket i5 extends only to or short of the plane of the center of rotation it of the ball it so that the joint can be readily disconnected by lifting the ball out of the socket when the holding means,to be described, is removed. This low socket also increases the angle of movement of the connector.
The suction nozzle is adapted to rotate in the operating plane around the axis i l which extends through the center of rotation i6 and is perpendicular to the surface to be cleaned. The connector ii however, is turnable in every direction around the center of rotation It to the extent determined by the position of a shoulder Ma which is adapted to engage the top of the socket for limiting the movement of said connector. This shoulder may, however, be omitted in certain instances to provide a maximum angle of movement for the connector.
socket joint pass through the center of rotationv i6, it is desirable that the ball and socket be held together by spring pressure which is always directed toward this point. In the embodiment shown this is accomplished by providing a pin l8 which passes transversely through the ball 14 and is provided with an annular groove [9 lo-' cated at the center of rotation it. In the groove ii] there is supported the bent over end of a guide member 2!] which extends in the direction of the axis ii and is turnably supported as at 2| in a leaf spring 22 which bridges the lower suc tion opening of the suction nozzle ii) and may be attached thereto as by pins 22a. In this construction the leaf spring 22 remains stationary for all movements. of the connector ii for the reason that the guide mern ber is free to rotate about the axis I! and the pin I8 turns about any desired axis passing through the point it.
Although the spring 22 has been shown as arranged in the suction nozzle and adapted to apply spring pressure directly to the center of rotation it of the ball and socket joint, it is to be understood that the spring may, if desired, be positioned Inasmuch as all axes of rotation of the ball and either at the suction opening or at the pin it or at the guide member 20 or that any of the above mentioned elements may be spring mounted.
In the above described embodiment the arc of contact between the ball I4 and the socket I5 is reduced to a minimum inasmuch as this contact is not relied upon to hold the parts in assembled position. Consequently, the socket l5 can'terminate at or short of the plane of the center of rotation IQ of the ball ll. The resiliently held together by means of t e spring 22 and guide member 20 above described. This arrangement is adapted to provide sufficient friction to prevent the suction nozzle from turning too freely and also provides suflicient resilience to prevent the joint from binding. It also assures an effective seal between the connector II and the suction nozzle III. The nozzle is accordingly adapted to turn in all directions about an axis normal to the surface to be cleaned and may also turn with respect to the suction hose so as to accommodate various irregular surfaces, thereby providing a three dimensional mobility, that is freedom of the suction nozzle to turn about three axes which cross or intersect each other. The angle of movement about certain axes may bemade greater than that about other axes by suitably positioning the shoulder.
Ila on the surface of the ball I.
Figs. 5 and 6 illustrate an embodiment 'in which agreater arc of contact is obtained between the ball I4 and socket I 5. In this emwithout restricting the rotational. movement thereof in a horizontal plane. The construction is otherwise" similar to that described above in connection with Figs. 1 to 3.
Fig. 4 shows a different embodiment in which the pin I0 is provided with a transverse bore 26 adapted to receive a pin by which the guide S are of said bar.
Although certain specific embodiments have been shown for purposes of illustration, it is to be understood that the invention is capable of various uses and is to be limited only in accordance with the following claims when interpreted in view of the prior art.
What I claim is:
1. A universal fluid-conveying joint for a suction nozzle having a .surface engaging portion, a connector adapted to connect the same to a suction conduit, a freely rotatable and pivotal ball and socket joint interconnecting said suction nozzle and connector and having an aperture through which the suction air passes, spring means holding said ball and socket joint in assembled position, an annular channel formed in said suction nozzle in a plane parallel to said surfac and means carried by said connector and engaging said channel'to limit the movement of said connector in certain directions.
2. In a universal fluid-conveying joint for a suction nozzle, a connector adapted to-connect the same to a suction conduit, a freely rotatable nected to the centerpf said pin, and a resilient bar extending across the aperture in said nozzle,.
said link being rotatably connected to the center I Gos'rA DAHL.
