Nrrnn STATES IMPROVEMENT IN ELEVATOR-BELT TIGHTENERS.
Specification forming part of Letters Patent No. 129,745, dated July 23, 1872.
Specification describing a new and useful Improvement in Elevator-Belt Tightener, in-
" vented by WILLIAM MERSON, of Danbury, in
' improved device for tightening an elevatorbelt and holding it until laced, and which shall be simple in Aconstruction and convenient and effective in operation, `enabling the ends of an elevator-belt to be drawn together and laced by a single person; and it consists in the construction and combination of the various parts of the device, as hereinafter` more fully de scribed. y
y A represents the elevator-case; B, the elel vator drums or pulleys, and C, the elevatorbelt, about the construction of which parts y vthere is nothing new. To the belt G, near one end, is bolted Va small plate or lug, D,to which is attached one end ofa short rope, cord, or strap, E, the other end of which is attached to a short shaft, F, passed through holes in the sides of the case A, and the ends of which project and are squared oiI' to receive a crank, G, or Wrench H. The other end ofthe belt C is secured to the caseAby screws, asshown in the Figs. 1 and 2 or it may be provided with a lug, D, and cord E, in the same manner as the iirst end. By this arrangement, by turning the crank G the cord or cords E will be Wound upon the shaft F to hold it from turning back. The crank G is then removed and'reversed so that its handle may rest against the case A and hold the shaft F from turning back While the lading is being done. When the lace has been secured the device is detached, and the holes` in which the shaft F works closed by caps.
This device enables a single one to do the work which has heretofore required two or three.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The plate D, strap E, and windlass F, ap
