JOHN M. SWANSON, OF CORRY, PENNSYLVANIA.-
MECHANICAL :fiar/Liann..
Specification of Letters Patent.
Patented Sept., 21, 1909.
Application filed September 5, 1908. Serial No. 451,835.
To all whom if may concern.'
Re it known that l, JOHN M. SwaNsoN, citizen of the United States, residing` at Corry, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in ll/iechanical llainmera of which tbe following is a specilication.
The present invention relates to improvements in mechanical hammers and. has for its object to provide a device of this character which embodies a novel construction whereby a blacksmith can do his own striking while welding` two pieces together or performing a similar operation.
rlhe invention further contemplates a hammer which is simple and inexpensive in its construction and which when installed in machine shops will eliminate the necessity7 of providing each blacksmith with a striker and thereby produce a great saving in labor.
For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construct-ion and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:
Figure 1 is a perspective view of a mechanical hammer embodying the invention portions being broken away. Fig. '2 is a horizontal sectional view through the same.
Corresponding and like parts are referred to in the following description and indicated in all the views ot' the drawings by the same reference characters.
Referring to the drawings, the numeral 1 designates the base and 2 a block which is mounted upon the base, the said block carrying an anvil 3 of any suitable type. EX- tending upwardly from the block upon opposite sides of the anvil are the standards 4, the inner faces of the standards being provided with the vertical guideways 5 loe- `tween which a cross head 6 is mounted.
The lower face of the cross head is provided with a hammer 7 designed to strike against the anvil as the cross head is reciprocated up and down, while the top of the cross head is connected to lazy tongs 8. These lazy tongs are pivotally connected at an intermediate point in their length to cross bars 9 at the upper ends of the standards, the upper extremity of the lazy tongs being loosely connected to an arm 10 which. projects laterally from the upper end of a slide 11. This slide is mounted within a guideway 12 and is provided with a rack 13 which meshes with a pinion 14 journaled between an upright 15 projecting from the base and a bracket 16 upon one of the standards 4. Rigid with the pinion 14 is a sprocket wheel 17 around which is passed a chain 18 the two extremities of which are connected to opposite ends of a t-readle 19 upon the base 1. It will thus be obvious that by placing the foot upon the treadle and rocking the same the chain will be drawn back and forth across the sprocket wheel 17 and will thereby alternately turn thepinion 14 in opposite directions so as to move the slide 11 up and down and thereby manipulate the lazy tongs to produce a reciprocating movement of the hammer. Attention is directed to the fact that the provision of the lazy tongs serves to magnify the movement so that the hammer' may be given a comparatively long stroke by merely rocking the treadle. Plates are preferably applied to opposite sides of the standards 4 so as to inclose the lazy tongs and prevent any accidents such as might be occasioned by the person of the operator coming into contact therewith. It will also be obvious that should it be desired suitable dies might be applied to the hammer and the anvil and the device utilized for stamping out washers from sheet iron, or for making similar articles.
Having thus described the invention, what is claimed as new is:
1. In a mechanical hannner, the combination of an anvil, a pair of standards projecting upwardly upon opposite sides of the anvil, a cross head slidable between the standards, a hammer upon the cross head, a slide mounted upon one of the standards, a lazy tong connection between the slide and the cross head, a rack upon the slide, a pinion engaging the rack, a sprocket wheel rigid with the pinion, a treadle pivoted between its ends, and a chain passing around t-he sprocket wheel and having the extremities thereof connected to opposite ends of the treadle.
2. In a mechanical hammer, the combination of an anvil, a pair of standards projecting upwardly upon opposite sides of the anvil, a cross bar connecting the standards, a cross head slidably mounted between the standards, a slide mounted upon one of the standards, an arm projecting from the upper end of the slide, lazy tongs pivotally connected between their ends to the before mentioned cross bar, one end of the lazy tongs being connected to the cross bar While the opposite end of the lazy tongs is connecty ed to the arm of the slide, a rack upon the slide, a pinion meshing with the rack, a sprocket Wheel rigid With the pinion, a treadle pivoted between its ends, and a chain passing` around the sprocket Wheel and havposite ends oit' the treadle.
In testimony whereof I affix my signature in presence of two Witnesses.
