NITED STATES PATENT FFICEQ THOMAS W. BROOMELL, OF CHRISTIANA,PENNSYLVANIA.
PlTMAN-BOX.
SPECIFICATION forming part of Letters Patent No. 355,435, dated January 4, 1887. I
Application filed June 5, 1886. Serial No. 204,206. (No modeLl Christiana, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Crank or Pitman Boxes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexeddrawing, making a part of this specification, and to the letters and figures of reference marked thereon.
The present invention has relation to that class of boxes or bearings formed in sections and provided with means for taking up the wear caused by the frictional contact of the journal or shaft thereof, and refers more particularly to the boxes for crank or pitman connections, and to the cross-head boxes of all engines, saw-mill crank-boxes, &c.
Heretofore it has been common to provide means for taking up the wear, consisting of a wedge forced against the box-section by the action of a spiral spring or screw.
Itis the object of the invention to improve the means heretofore employed whereby the action of the wedgeis morepositive; andthe invention consists in connecting with an upright Wedge a horizontal wedge controlled by a spring which forces it forward, said wedge forminga support for the upright wedge and acting as a follower to automatically force it against the movable box-section, whereby said section is made to compensate for wear, as will be hereinafter described and claimed.
. V In the accompanying drawing, Arepresents the cross-head end of the connecting-rod, and
B O the two box-sections, formed of the metal usually employed for the purpose. Theboxsection B, which is movable, has an inclined outer face, a, and between it and the inner end of the rod A is located an upright wedge, D. The lower end of the wedge D rests upon and is supported by a horizontal wedge, E, which I term the follower-wedge, and back of this wedge is located a spiral or otherjform of spring, F, which forces it forward as wear occurs on the box and crank-pin, elevating wedge D and forcing inwardly the box-section 13.
It is evident that the means above described may be applied to all classes of boxes or bearclined face, a vertical wedge interposed between said face and cross-head end,and a horizontal wedge having the upper inclined face
