Description

AM. PHOTO-LITRO. C0. (USBORNES PROCESS.)
UNITED sTATEs PATENT oEErcE.
HORATIO ALLEN, OF NEW YORK, N. Y.
CUT-OFF.
Specification of Letters Patent No. 5,745, dated August 29, 1848.
To all whom t may concern.'
Be it known that I, I-IORATIO ALLEN, of New York, N. Y., have invented new and useful Improvements in Cut-Offs, of which the following is a specification.
The combination which I have invented to form a cut 0H" for steam engines will be readily described by reference to the drawing annexed hereto. I
F is the lifting rod which is to be raised as usual by the toe on the rock shaft.
G is t-he steam valve and H the valve stem.
B is an arm fastened on the lifting rod F.
On the arm B is placed the sliding piece Al the two being adequately connected by the groove 0 and tongue P. On the valve stem I-I are fastened on suitable centers t-he two friction rollers I, I. When the parts are properly adjusted as represented in the drawing, the rollers I, I, just' clear the upper straight surface of the sliding piece A,
when the valve is in its seat.
As thus far described, the valve G would, on motion being given to the engine have the same motion as the lifting rod F.
To provide for the return of the valve to its seat, sooner than the lifting rod returns to its state of rest, is the object of this invention.
The surface 1^, s, t, of the sliding piece A is made about of the shape represented in the drawing.
The vertical lever C is connected with the lifting rod by the link E and centers at L and V as represented.
By means of a pin at M the sliding piece A is connected with the vertical lever C.
c The rod D is connected with the lower end 4,of the vertical lever C by a pin at Y. The
rod D receives a reciprocating motion, derived from any partV of the engine having a motion coincident with thatv of the piston, and of such range as may be necessary.
If we suppose the engine in motion, and
the parts to have the motions indicated'by arrows, it will be perceived that as the lift* ing rod F rises, the sliding piece A will have a motion along the arm B and that the `surface t, s, r, will be brought under the rollers I, I, and that consequently the valve will be lowered as fast as and when the surface t, s,
T, will permit. The `point of stroke at which the surface t, s, 7', Will allow the valve to return to its seat, will depend on the point of connection between the piece A'and the vertical lever C. By changing the pin which connects these4 to any other hole in A a change in the point of restoring the valve to its seat will necessarily follow.
The introduction of the sliding piece A in combination with'the arm B and rollers I, I, i
on the valve stem and with a motion coinci* dentwith that of the piston the sliding piece having a descending surface by means of which the valve is allowed to return to its seat before the end of the stroke, substantially as described herein. f New York, Aug. 17, 1848.
HORATIO ALLEN. Y*
