WILLIAM sMEEo, 0E EocHEsTER, AssIcNoE rroEIMsELEv AND GLEN a HALL ISIANUFACTURINGLGOMPANY, OF BRIGHTON, NEW YORK.`
Letters Patent No.-109,846, dated December 6, 1870.
IMPRVEMENT IN SHAFT-COUPLINGS.
The' Schedule referred to these Letters Patent and making part of the same. i
.To all whom it may concern Be it known that I, WILLIAM SMEED, ot Rochester, count-yof `Monroe and State of New'York, have invented certain new and useful Improvements in Shaft-Couplings, of which the following is a full. clear, and exact description, reference being had to the aecompanying drawing, making part of this speciication, iu which l vFigure 1 -is a perspective View of' my improved coupling, and t Figure 2 is a transverse sectional view.
The invention relates to that class of couplings known las universal or tumbling joints, and which are inclosed by a casing, to prevent anything from becoming entangled with said coupling when it is in motion.
The invention consists in certain features of construe-tion, which are designed to secure economy, durability, convenience in taking apart or putting together, and perfectsecurity when in operation, as will be fully set fort-h and explained in the following description.
A represents a hollow shell or casing, of a globular form, and provided upon one side with a neck or arm, A', cast, by preference, in one piece with the shell.
Neck A- is cast with a socket, of suitable form and size, to receive one end of the shaft to which the coupling is to be attached.
I5 is a rim or'lange upon the outer end of neck A', and the neck between this flange 'and the shell may be made to serve as a bearing, to support the coupling and shafting.
Upon the inside'ofI shell A, at its greatestdiameter, are two bosses, 'a a', placed diametrically opposite .to each other, one of which, c, is perforated, said perforation extending `entirely through the shell, as shown in fig. 2, while the other one, 'agis provided with a socket or eye, which does not extend through' the shell, but is left blind.
C is an' intermediate or connecting ring, made substantially like those generally employed in this class ol' coupling, and connected with shell A by means of bolt or pin C. V
One end of this pin rests in a socket in boss a', and the other end in the perforation in a boss, a.
D is a sliding plate, confined in a dovetailed groove, as is plainly shown in tlg. 2.
After ring Gand bolt C', are placed in proper position, plate D is slippedA in, and said bolt is thereby securely held in place.
At the rear end of the dovelailed groove there is a recess at d, into which the inner end of plat-e I) may be upset, so that it cannot-be accidentally displaced, while at the same time it can be driven out by means of a-hammer and set or cold chisel.
E is a hub, .provided with a suitable socket forthe reception-,of a shalt, as at` e, iig. 1, and is expanded into ears 1 Each ot' these ears perforated and connected with intermediate rings O. by means of bolt F, which passes through said ring at right angles to bolt or pinG, bolt F heilig secured by latch f or its equivalent.
I n casting the various parts forming this coupling, I iind it desirable to chill all of the holes through which the pins or'bolts pass, as the durability ofjoiut is very much increased thereby.
Itwill be readily seen that the inside bosses a. c1.- serve not only to furnish an additional length of bearing for pin C', but also to maintain C in a central position with reference to shell A.
It will also be apparent that by casting shell A in a spherical form, I not only reduceits size, but also give it the greatest possible strength for the weight of iron required.
Having now described my invention, v
XVhat I claim as new, and de"`re to secure by Letters Patent, is
1. The shell A, provided with a socket or blind'eye, as at a,.adapted to receive and support one end of the pin c', to which are attachedv the remaining parts of the coupling, substantially as described. v
2. rI he shell A, provided with bosses a a upon its inner surface, for the purpose' of' maintaining the riug/ C, in a central position, as set forth. v
3. The shell A, provided with the dovetailed groove, in combination with'the sliding plate D, for securing the pin in the perforation at a, and the blind eye at a', substantially as set forth.
his WILLIAM X SMEED.
mark.
