UNITED STATES PATENT OFFICE.
JAMES CLAYTON, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN CRANK-WRIST CONNECTIONS.
Specification forming part of Letters Patent No. 47,522, dated May 2,1865.
T0 @ZZ whom, it may concern:
Beit known that I, J AMEs CLAYTON, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Crank or other Wrist Connections for Steam-Engines and other Purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyin g drawings, forming part of this specitication, in which- Figure l is a side view of a portion of a direct-action steam-pump with my improvement applied, partly in section. Fig. 2 is a transverse vertical section of the saine.
Similar letters of reference indicate corresponding parts in both figures.
This invention relates to making the connection of a crank or other wrist with a piston rod or other reciprocating piece, from which it receives, or to which it transmits,
rotary motion by means ot' a slotted cross-` head without a pitman. y
lt consists, lirst, in a certain construction ot' the box `which receives the crankwrist, whereby facility is afforded for tightening it, both upon the crank-pin and within the slot ofthe cross-head, when it has become loose by wear.
It also consists in so providing or applying a guide for the cross-head as to dispense with anges ou the aforesaid box.
To enable others skilled in the art to construct my invention, I will proceed to describe it with reference to the drawings.
A is the slotted crosshead, rigidly attached to the pistonrod E. C is the box connecting the wristh of the crank B with the crosshead. This box consists of -two wedge shaped side pieces, b b, and two lining-pieces, c c. The outer sides of the lining-pieces c c are made of sloping form, corresponding with the inner sides of the side pieces b b, and the inner sides are hollowed out to forni the bearing for the crank-wrist.
The side pieces o c have slotted lugs b b provided on their upper ends to project over the tops of the lining-pieces, and the said lugs are connected with the lining-pieces by means of screws d d, which are secured rmly in the lining-pieces, and which pass through the slots in the lugs b b thereof, and -nuts e e, which are fitted to the said screws above and below the lugs. By properly adjusting the screws d d by means ofthe nuts e e the side pieces are caused, by their wedge-like action, to set the lining-pieces as tight as required upon the crank-wrist, and the lining pieces are caused to set out the side pieces as tight as required between the sides otl theparallel slot g of the cross-head.
Whenever any wear has taken place between the crank-wrist and the bearing in the lining-pieces, or between the side pieces and the sides of the slot in the cross-head, whith requires the tightening of the box, the tightenin g can be effected by screwing up the nuts on the screws. Each sidepiece can be separately adjusted when necessary.
The lining-pieces c c are ofsuch width as to tit between the shoulders of the crank-wrist,
and the side pieces b b are of corresponding width. The thickness of the cross-head also corresponds. f
To prevent any twisting of the yoke, guides a c are provided in the bed-plate F, between which the lower partof the cross-head tits snugly, but easily. 'lhese guides obviate the necessity of dan ges on the side pieces of the box.
I do not claim, broadly, making the outer sides of the lining-pieces and ot'ytheir box taper and drawing them together by a wedgelike action produced by the operation of a screw; but
What I claim as my invention, and desire to secure by Letters Patent, is`
l. The combination of the lining-pieces c c, having their exterior sides of sloping form, the independent wedge-shaped side pieces b b, the screws d d, and the nuts e e, substantially as and for the purpose herein set forth.
2. In combination with the said liningpieces, side pieces, screws, and nuts, applied within a cross-head, the guides wa, provided for the cross-head, substantially as and for the purpose herein described.
JAMES CLAYTON.
