STEAM HAMMER,
'IlII/IIIIIIIIII I 1 'IIIIIIIIIIII PETER L WEIMER, OF READING, PENNSYLVANIA.
STEAM-HAMMER.
Specification of Letters Patent No. '10;486,datedJanuary31, 1854.
7 To all whom timely concern:
Be it known that I, PETERL. WEIMER, of:
Reading, in the county of Berks and State of Pennsylvania, have invented a new and F useful Improvement in Steam Forge-Hammers; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed draw-:1 ing, making part of this specification, in
' 7 the slide valve 2 by means of the slotted Which- Figure 1 is a side elevation of a steam I hammer. Fig. 2 is a plan on the line A A. i Fig. 3 is a side view of the adjusting wedge. Fig. 4 is a perspective view of the adjusting wedge. Fig. 5 is a section of the hollow piston and plunger.
The letters of reference in all figures corresponding, Fig. 1, A is the anvil, H the hammer, L the lever or helve, B the spring or tappet.
8 8 are supports for the spring.
D is the link connecting the hollow piston E with the lever or helve L.
G is the steam cylinder, F the packing gland.
G G is the steam chest.
2 is an ordinary D slide valve.
6 is the opening admitting steam into the chest, 4 the steam port, 3 the exhaust port.
K K is the valve stem.
R is a small cross head keyed fast to the valve stem.
S is a forked arm fastened to the shaft 9 and lies loose in contact with the cross head R.
Y 5, 5, are the standards for guiding the valve stem K K.
T is an arm fastened to the shaft 9, and latches into the catch U.
X is a spiral spring for the purpose 'of' keeping the catch U in its place when the hammer rises ofi the anvil.
W are toggle levers one end of which is fastened to the anvil. The other end is secured to the bed plate of the hammer.
V is the connecting rod between the toggle W and the catch U.
J is an arm made fast to the shaft 9.
I is a weight fastened to the armJ for the purpose of carrying back the valve 2 after the force of the blow of hammer has detached the arm T from the catch U.
P is a latch for the purpose of securing the arm J in a stationary position when it helve.
is desirable not to use this part of the apa paratus.
N'N are hand flevers for the purpose of varying the blow of the hammer as well .as for adjusting 'thehammer to the 1 various thicknesses of :material to be forged, by means of the wedges O O to which they are connected and the valve stem K K.
M is an arm fastened to the helve of the hammer and is forthe purpose o'f-op'erating valve stem K ,K. i
'7 .7 are the supports ofthe journals of the The great disadvantage the present helve hammers in taking stea-m before they strike I their blow is my object to'over'come and so arrange the valve that the steam cannot enter the cylinder until the hammer has struck its blow, thus allowing the hammer its full power.v At the same time all the various blows are retained by means of the slotted valve stem and adjusting wedge.
IV is a toggle one end of which is fastened .to the anvil. The other is fast to the bed anvil) to crush or spring in its bed, there-- by causing the center of the toggle to move in the direction of the arrow, drawing with it the catch U by means of the connecting rod V and releasing the arm T from its holdin the. catch U, when the weight I on the arm J will fall, carrying with it the valve 2 by means of the forkedarm Sf operating on the small crosshead R, which i is keyed on the valve stem K K, and admit the steam into the cylinder through the n passage 4, when the hammer will rise and, the spiral spring X will draw the catch U and toggle W into position to again receive the arm T, when the hammer in its rise shoves the valve forward by means of the arm M and thevalvestem K K and small cross head R operating on the forked arm S raising the weight I on the arm J, when the apparatus is ready for another blow of the hammer. In using this apparatus the arm and weight is first detached from the catch P and the back adjusting Wedge O is withdrawn toits thinnest part so that the hammer in falling cannot by means of the arm Ml open the valve 2. The forward adjusting wedge is used to vary the exhaust steam as well as for gaging or holding the hammer against the spring, which is effected by withdrawing said wedge, when the valve 2 will remain stationary, and the full pressure of steam remain under the piston thus preventing the hammers falling. The various changes are efi'ected without stopping the hammer; neither is it necessary to latch the arm J in the catch P when not using this part of the apparatus, though by 'doing so it is out of gear. By this arrangement a hammer will be able to strike a more that when the steam is admitted into the cylinder before the blow is struck it serves to in a great measure arrest the force of the blow by striking the steam in the cylinder before the hammer reaches the anvil or material thereon.
by means of the recoil of the anvil caused by the blow of the hammer. But
I claim The arrangement of the toggle W, the catch U, the arm T, the arm J, the weight I, and shaft 9 for the purpose of opening the valve, admitting steam into the cylinder,
from the concussion or spring of theanvil' in its bed caused by the force of the blow of the hammer. i
