GEORGE F. SUDENGA AND ELMER E. KEOK, OF GEORGE, IOWA.
POWER-HAM IVI ER.
SPECIFICATION forming part of Letters Patent No. 565,523, dated August 11, 1896.
Application filed January 27,1896. Serial No. 577,047. (No model.)
To all whom) it may concern:
Be it known that we, GEORGE F. SUDENGA and ELMER E. KECK, citizens of the United States, residing at George, in the county of Lyon and State of Iowa, have invented a new and useful Improvement in Power-Hammers, of which the following is a full and complete specification.
Our invention has reference to improvements in power-hammers. Its object is to provide a simple construction by which the blow may be supplied with little friction, great force, and small loss of power, and by which all classes of work usually performed upon a blacksmiths anvil, such as pounding out plow-lays, cultivator-lays, disks of harrows, dro., can be quickly and skilfully accomplished, without the physical strength usually demanded, by means of a hammer driven by steam, set in gear by a foot-lever, leaving the hands free to direct the motion of the parts upon which the work is to be performed. We accomplish these results by the mechanism shown in the accompanying drawings, in which like parts are designated by similar letters of reference throughout both views, and in which- Figure l is a complete view of our device in side elevation. Fig. 2 is a detail sectional view of drive-shaft, showing the attachment of crank-shaft.
Referring now to our construction in detail, A represents the base, upon which our device rests, and A2 the anvil. To the base are attached by bolts two upright standards S S, held together at the top by iron crosscap K3. Standards S S are preferably constructed of wood or iron and braced by crosssupports B3 B3.
B is the belt, by which the power is conducted to the drive-wheel B', supported upon boxing S3.
S2 is the drive-shaft, turned by drive-wheel B', having a crank-arm G, by which crankshaft O2 is driven.
B2 is the balance and brake wheel on opposite vend of drive-shaft. Y
C is the hammer-lever, operated by shaft O2, to which it is loosely attached and can be suitably adjusted in and out by thumbscrew C.
Hammer-lever C is pivoted at C5 to crosssupport B3 by means of shaft O3, upon which it works up and down as a fulcrum.
W is a tightener-wheel supported by leverarm T4, working upon shaft X, through crosssupport B3, and operated by foot-lever T and its connective arm T3. On the opposite end of shaft X and operated by same lever T is brake-arm T3, with brake T6.
T2 is lever-spring.
Referring now in detail to the parts of the hammer itself, H is the hammer-handle; H2, the hammer-head. Handle H is pivoted upon K2 to top cap K3, upon which (K2) it works as a shaft. Loosely pivoted to handle H at K' and K are handle-arms H and H3, which are round and operated loosely and without connection inside of lever-arms H3 and H4, respectively. Arms H6 and H4 are loosely pivoted to shaft-arms O by shafts C3 and O4.
H7 and H5 are expansive springs working against cups at ends of arms H6 H4 and H H3.
Having now referred to the parts, we will describe their operation. Power is applied to drive-wheel B by belt B, which can be set in and out of motion by tightener-wheel W, operated by foot-lever T, which may be Acurved continuously around the base and operated at any point. Drive-wheel B' propels shaft O2, by means of crank-arm G, up and down and raises and lowers end of lever C. The motion of lever O, working upon shaft O3 as a fulcrum, alternately raises and lowers arms H7 and H5 and arms H and H3, working loosely in them. The alternate motion of arms H and H3 communicates the blow to the handle H, working on shaft K2. It will be observed that the outer arms H and H3, when raised, give the blow by the force on outer end of handle H, and arms H3 and H4, when raised by force applied toward inner end of handle H, raise the hammer. Spring H7 assists in forcing up handle-arm H', and thus in giving the blow, and spring H5 assists in raising handle-arm H3 and in raising the handle.
Spring T2 is a contractile spring and its tension holds brake T6 against brake-wheel B2 when foot-lever T is released.
Having fully described our device, what we claim as new, and desire to secure by Letters Patent, is
In a power-hammer, the combination with IOO a suitable base and supporting-frame, of rounding the arms, substantially as shown crankshaft S2, hammer-operating lever O, and described. rfulcrumed upon the frame and. connected In testimony whereof We affix our signw With the crank-shaft by shaft C2, tubular tures in the presence of two Witnesses.
