Description
C.A. SGHULTZ, OF NE\V YORK, N. Y.
IMPROVEMENT lN STEAlVl--ENGlNES.
Specification forming part of Letters Patent No. QILSMV?, dated October 26, 1858.
To @ZZ whom it may concern.-
Be it known that I, C. A. SoI-IULTZ, of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe saine, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a longitudinal elevation; Fig. 2, a plan; Fig. 3, a side view of the slide-valve; Fig. 4l, a top view of the same; Fig. 5, a front view of the revolving eanrwlieel; Fig. 6,21, side view of thesame. Fig. 7 is an end view of the socket and guide-rods, Fig. 8, a side view of the same.
The construction of the engine is as follows:
A is the frame.
B is the cylinder.
C is the piston-rod.
D is the cross-head, which works on slides 7.: 7.-.
E is the connecting-rod.
F is the crank.
G- is the crank-shaft.
J is the steam-chest.
H represents a balance slide-valve, of which the lower part is a common slide-valve, with foureolumns, a n, u a, Figs. 3 and 4c, one (standing upright) on each corner, on the top of said valve. 0n the topfof columns a In a n is a plate, r. Fig. 3, of the same area as the valve H. The valve H, cola m ns 'n a a a, and top plate, r, are cast solid. Four holes are east or drilled in the upper plate,-r, which run about halfway into the columnsaw a yn., to be used for spiral springs n rb u, Fig. 3, which will be used to press against cap Q, Fig. 3. This cap Q is fit ted on the upper plate, r, onvalve H, as shown in Fig. 3, and serves as a packing, in combina tion with spiral springs lu 'u o U. As this cap will bear against the top or cover of the steamchest J and at the same time press thel valve H against the face of the cylinder D, no steam can enter the top of the cap Q. There will be no pressure on the valve H, and not more poweris required to operate the valve H, but just to move the weight ofthe same.
K is the valvestem, with friction-rollers p p attached to it, Fig. 2.
Z is a lever, for which m is the guide. The
lever Z is intended to serve in place of the wellknown unhookinggear. This is done by moving the leverZ toward revolving shaft N. This movement will bring the friction-rollers p p underneath the valve-stem K, so that the same cannot come in contact with the revolving cam-wheel M. The revolving earn-wheel M, Figs. l, 2, 5, and 6, gets the motion from the crank-shaft G by means of bevel-wheels O O and revolving shaft N, Figs. l and 2.
The revolving cam-wheel M is constructed in two parts, a and b, of which b is the part which opens the valve H, by means of cams@l c, operating against frictionrollers j) p on valve-stein K. This part b of revolving eamwheel M is fastened to revolving shaft N. The part c of revolving earn-wheel Mis movable and not fastened to revolving shaft N. The part a of revolving cam-wheel has two cut-oli' cams, d d. The part a of revolving cam-wheel is operated by guiderods e e in socket L, Figs. 7 and S. Theguide-rods ce form a taperthat is, they are far apart where fastened to socket L and near together on the outer end. These two guide rods e e fit the two holes s s, Fig. 5. One of these holes is in part a and the other hole is in part b, and will bring the opening-earns c c and the cut-off earns d d close together, Figs. 5 and G, when the same are en tered with their outer ends, and will bring said cams far apart when pushed in all the way up to socket L. The slots t t, Fig. 5, allow the guide-rods e cto move freely in and out.
lD is the governor, Figs. 1 and 2.
i is a small rod inside of the governor-eolumn. by means of bell-crank 7L and rod g. Rodgis attached to fork j", which is fitted into slot w in socket L. The socket L is fitted onto revolving shaft N, so as to move freely back and forward.
rThe operation of the engine is as follows: As there is no difference in the steam-ports of the cylinder from the common slide-valve, it needs but little explanation. The engine will start when the steam enters the steamehest Ji. The revolving cam-wheel M will make the same revolutions as the crank-shaft G by means of bevel-wheels 0 O and revolving shaft N, and the same will open and shut the valve H by means of opening-cams c @and cutoff earns I c c, i
This rod is connected with socket L d d. These cams c c and dd operate the valve H by coming in contact with friction-rollersp p on valve-stem K. The part a of revolving,` cani-wheel M, with cutoff cams d d, is movable, and therefore can be regulated to cut off steam at any desired length of stroke, which is done by moving socket L heck end forward,
r so that the guiderods e e will pass in and out the holes s s in revolving` cam-wheel M. This can be done at any time when the engine isin full motion. The governor l? is attached to socket L to regulate the speed of the engine. Whenever the engine runs fester than a cer tain Speed, the governorhalls will fly out and lower the rod 1J, Whieh'will move the socket L hack by ineens of hell-crank l1, and rod g, in
