BALL-AND-SOCKET JOINT.
SPECIFICATION forming part of Letters Patent No. 625,412, dated May 23, 1899.
Application filed October 9, 898: Serial No. 694,974. on model.)
To all whom, it may concern.-
Be it known that I, CHARLES WALTER PASH- LEY, residing at Sinderland Lane, Dunham, in the county of Chester, England, have invented certain new and useful Improvements in Ball-and-Socket Joints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to improvements in ball-and-socket joints and bearings. In the latter as generally made hitherto the wear can be taken up only by setting one portion of the socket or one of the so-called' cones, as the case may be, up toward the other, and consequently moving the ball or moving portion of the joint till its center stands away from its original position by a distance equal to the take-up.
The object of the invention is to endow any joint or bearing of the type just described with a faculty of being taken up without either portion of the socket or either cone being advanced toward the old center of the joint more than the other portion or cone or without moving the ball or moving member of the joint out of its original position. That object is realized by the means illustrated in the accompanying drawings, which are to be taken as part of this specification and read therewith.
Figure 1 is a side elevation, partly in section, illustrating the application of the in- .vention to the tracer-rod of the engravingthe rod D passes and is capable of working freely therein in a vertical direction. These parts are not affected by the present invention, and for that reason more detailed specification of them is unnecessary, further than this, that the bracket stands for the fixed part that carries the improved joint or bearing.
There is a cone :0 on each side of the ball distance between the two.
00 Both cones 50 are of a proper diameter to hold the ball 032 between them in practically the same way, as far as the mere holding it is concerned, as the moving part of any ball or socket joint has been usually held hitherto. The faces which bearupon the ball 02 are straight. The two cones are held up to the ball :0 by two bushes 09 m.
The bush is T-shaped in cross-section. One portion 50 of it fits down upon the respective face of the respective cone x and the central portion a which is parallel with the axis of the rod D, fits up to the respective face of the said cone, each in the way usual in conebearings, while the third portion to stands in a recess x in the bracket 0, but at a proper distance from the bottom of that recess to allow of it being moved up to the said bottom to take up wear, as indi cated in Fig. 1, which shows an appreciable Further, the portion a is prolonged for as much as is required by the take-up action described farther on.
The bush x is L-shaped in cross-section and embraces the respective cone 00 in the same way as the portions x m of the bush 00 embrace their cone at. a? is an annular prolongation of that portion 50 of the bush which is alined with the portion 00 above described. There is a suitable recess in the bracket 0 to receive the bush The outer surface of the portion 0: and the inner surface of the prolongation x are screw-threaded to engage with each other. The outer surface of the prolongation 00 and of the portion 3 and the opposite surface of the last-mentioned recess in the bracket 0 are screw-threaded to engage with each other, the two screw-threads just described being the one between the bush m and the bush m and those between the bush as and the bracket C are dissimilar in pitch, the latter being twice as fine as the former 2. e., if the thread of the bush a has twenty threads to the inch that of the'bush 00 has forty threads.
is a pin, and as a locking-nut, for respectively holding the bushes 00 m in their adjusted positions to the bracket 0. g
The parts of the improved joint are put together in the following way: The cones 03 0:
are inserted in their respective bushes m and the bush 0:, with the ball x resting upon the respective cone m is screwed into the bracket 0 until that ball is in its correct position. The bush 50 is next screwed into the bush x until its cone just touches the ball :2 The hole for the holding-pin 00 is then drilled, half of it in the bracket 0 and half of it in the bush m and the pin 00 inserted therein. The locking-nut x is then screwed over the bush or and up to the bracket 0 to prevent the said bush working loose.
To take up wear, the locking-nut x is loosened and the bush 0; screwed up until both cones 90 press with suflicient tightness upon the ball 00', whereupon the nut 00 is screwed up again.
The above-described proportion between the two screw-threads insures a constant position for theball 00 no matter how much wear has to be taken up, because the bush 00 is moved twice as far in the direction of the rod D as the bush :0 is, the motion in the same direction of the bush m overlapping half of the corresponding motion of the bush :0 The said proportion between the screwthreads is the correct one for a joint where the weight of the moving part will not cause more wear on one side than on another. meet a case in which the wear is unequal, that proportion may be varied according to the excess wear on the one side.
I claim- In a ball-and-socket joint, the hereinbefore-
