CAM ACTUATi'ID, SLIDING HEAD HAMMER PITMAN F'ild Aug. 7, 1947 4 TTORNE Y Patented July 31, 1951 CAM ACTUATED 2,562,642 SLIDING HEAD HAMMER PITMAN 1 August Saxer, Thalwil, Zurich, Switzerland Application August 2, 1947, Serial No. 767,183 I In Austria July 11, 1946., I;
6 Claims.
My invention has for its object the manufacture of tools and/or other similar equipment in such manner that for the formation of grooves and/or flutes as are found in such equipment, tools in the form of a hammer are used. These tools are guided by special brackets and driven by gearing, the hammers to be evenly distributed along the circumference of the work-piece. These hammers, which have specially designed hammer-fronts, tap in a quick sequence upon the work-piece, thereby forcing the material to flow by creepage out of the grooves and/or flutes and in the direction of the remaining studs.
It will be seen that in order to obtain accurate results, it is essential that the hammers are correctly guided and sufficiently oiled to prevent resistance. It has been found that the best results are obtained in the construction herein shown and described, reference being had to the accompanying drawings, in which,
Fig. 1 is a fragmentary view, partly in section, of my hammer;
Fig. 2 is a side elevation, partly in section incorporating my invention.
In the known constructions, the head of the hammer is fastened to a connecting rod by ball and socket. This bearing is secured by counterpane and tightly screwed against the hammer.
The connecting rod is actuated by an eccentric sheave and head. The forming tool is mounted on the front of the hammer. The hammer itself is guided by the guide-brackets. In this con struction, it is impossible to provide adequate oiling arrangements for these parts asthey op- It will thus be seen erate under great pressure. that unless some means are provided, the parts would run dry with consequent excessive wear and possible blocking of the elements.
My invention has for its object means for overcoming this eventuality. As shown in the drawing, the head of the hammer I is made of the same piece as the connecting rod 2, This is further actuated by an eccentric sheave 3 and head 4, thus imparting thereto an undulating movement. To allow for this movement between the guide-brackets 5 the hammer head is guided by a slide-block 6, which is of frame-like shape and flexibly connected to the hammer head by a through-bolt I. The tool 8 which works on the work-piece (not shown in the drawing) specially shaped and fixed to the front of the hammer I.
It will be seen by reference to the drawing that the connecting rod and the hammer are made of the same piece which also carries. the
tool. The hammer is guided by a four-edged and hollow slide-block, to which it is attached, and which, due to its width, imparts a free undulating movement to the connecting rod in a vertical plane. With this arrangement the dimculties of oiling the bearings are overcome. My invention has the further advantage that the tool, which forms the grooves and/or flutes, imparts a squeezing action to the work-piece, as well as hammer blows, due to its undulating movement. This augments the creeping of the material to be forced out of the grooves.
What I claim as new and desire to be secured by Letters Patent is:
1. In apparatus of the type described for producing grooved work pieces, the combination of a rotating shaft, an eccentric on the shaft, a connecting rod rotatably connected at one end with the eccentric and having at the opposite end a hammer-tool portion integral with the connecting rod, a hollow slide-block pivotally connected with the hammer-tool portion, and. guideways slidably guiding said slide-block for rectilinear movement.
2. In apparatus of the type described for producing accurately grooved work pieces, the com- I bination of a rotating shaft, an eccentric on the shaft, a connecting rod having at one end a bearing rotatably engaging said eccentric and having at the opposite end a hammer portion integral with the connecting rod, a slide member pivotally connected with said hammer portion, and guideways slidably guiding said slide member for rectilinear movement.
3. In apparatus of the type described for producing accurately grooved work pieces, the combination of a rotating shaft, an eccentric on the shaft, a connecting rod having at one end a bearing rotatably engaging said eccentric and having at the opposite end a hammer portion integral with the connecting rod, a hollow cylindrical slide member surrounding the hammer portion and pivotally connected therewith on an axis parallel to the axis of the shaft to permit limited pivotal movement between the slide member and hammer portion, and guideways slidably guiding the slide member for rectilinear movements in a direction substantially perpendicular to the axis of the shaft.
4. In apparatus of the type described, the combination of a rod having at one end a hammertool portion integral with the rod, means connected with the opposite end of said rod for imparting undulant reciprocation thereto, a hollow slide-block pivotally connected with the hammertool portion, and guideways slidably guiding said slide-block for rectilinear movement.
5. In apparatus of the type described, the combination of a rod having at one end a hammertool portion integral with the rod, means connected with the opposite end of said rod for imparting undulant reciprocation thereto, a slide member pivotally connected with said hammer portion, and guideways slidably guiding said slide member for rectilinear movement.
6. In apparatus of the type described, the combination of a rod having at one end a hammertool portion integral with the rod, means COIL- nected with the opposite end of said rod for imparting undulant reciprocation thereto, a hollow cylindrical slide member surrounding the hammer portion and pivotally connected therewith on an axis parallel to the axis of the shaft to 4 permit limited pivotal movement between the slide member and hammer portion, and guideways slidably guiding the slide member for rectilinear movement in a direction substantially perpendicular to the axis of the shaft.
