Letters Patent No, 84,161, dated November 17, 1868.
IMPROVEMENT IN SHAFT-COUPLING. m
The Schedule referred to in theseLetters Patent and making part of the same.
To all whom it may concer-n Be itknown that I, A. Blennow, of Hamilton, in the Province of Ontario, 1n Canada, have invented anew and improved Coupling for Shafting; and I do hereby declare that the followmg is a iull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same,
cation.
This invention relates to a new and improved couphng for shaftlng ot machinery, by which shafts maybe connected in such a-manner as to admit of being roor when formin g a greater tated freely when out of line, or less angle with each other.
The invention is 2 pplicable to various kinds of maeh'nes, some of which are in very common use, such, for instance, as threshing-machines, horse-powers, Src.
In the accompanying sheet of drawings`- Figure l is a vertical sect-ion of my invention, taken in the line x x, fig. 3.
Figure 2, a longitudinal section of the same, taken in the line y y, g. 3.
Figure 3, a vertical section of the same, taken in the line z z, tig. 1.
Similar' letters of reference A represents a shaft quite shut, leaving at each end a semispherical shell, B. The shell and shaft may be of cast-iron, and all cast in one piece, if desired. I do not, however, coniine myself to any precise mode of construction.
Figs. 1 and 2, when united as indicated by the red indicate like parts.
lines, give a correct idea,of the shaft and shells.
The internal parts ofthese shells, it will be seen, are positions, line of section at right angles to that of the other. The shaft A is fitted in a suitable bearing, C.
In each shell B there is fitted a ring, D, and through these rings bolts E pass, in which the rings are allowed to turn freely, the ends of the bolts being fitted in the shells.
The` rings D are considerably smaller in diameter than the inner diameter of the outer parts of the shells, and kthe portions of the 'lings through which the bolts E pass have projections or hubs, a, which extend to the inner surfaces of the shells, as shown clearly in figs. l and 3.
The interior of the rings is not circular, like the exreference being had to the accompanylng drawings, forming part of this specione shell leaving its terior, but has an oblong or oval form, as shown in iig. 3, and the inner diameter of the rings gradually contracts froni their front to their inner ends, as shown clearly in 1.
F F represent sockets in which the shafts G G, which are connected by the device, are secured.- (See figs. 1 and 2.)
The inner parts of these sockets are made with a swell, b, of globular' form, the diameter of which is slightly less than theinner diameter ofthe interiorjof the rings I), so that the'sockets may work eely within therings or bolts H H, which pass through the swells b of the sockets, and :'-re iitted in the rings D. L(See, more particularly, iig'. 3.)
The swells b of the sockets aresiotted, shown at ar, to admit ofthe bolts E passing through them without inteifering with the free play of the sockets F in the rings, and the bolts H ofthe socketsFhave holes made centrally through them, to admit of the bolts E of the rings D passing through them.
By this arrangement it will seen that the shafts G.
are connected to the shells by what may betermed universal joints, and that the shafts may be placed at a greater or less angle relatively with each other, and both allowed-to rotate freely, and either to turn or drive the other. i'
The device also is extremely strong and durable, in consequence of the bolts E H being long, Qone passing through the other, and no short pivots used.
Having thus described my invention,
I claim as new, and de "re to Vsecure by Letters Patent- The 'shells B Bon shaft A, in combination with the rings D, and sockets F F, which receive the .shafts G G, the rings and sockets being connected together and to the shells respectively by the bolts E H, with the bolts E passing through the bolts H, all being constructed and arranged substantially as and for the purpose set forth.
Hamilton, 15th August, 1868.
