`,Hite/lated May f2.4, 1.92.1.,-
Application filed September 2, 1920. Serial No. 407,663.
To all whom t may concern:
Be it known that I, EwART E. PETERSON, a citizen of the United States, and residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Rock-Drilling Machines, of which the following is a speciication.
This invention relates to an improved portable apparatus designed particularly for use as a rock drill wherein provision is made for imparting the rapid series of blows to the drill and at the same time automatically turning the drill on its aXis as is de sii-able in devices of this character.
The construction involves a gasolene or similar engine having the crank shaft or driven shaft thereof provided with a cam member arranged to impart a series of blows to a drill carrying spindle, the apparatus as a whole being utilized to maintain constant engagement between the cam and spindle. A spindle turning member is arranged to be given an intermittent movement through the cam, so that during the impact or immediately following such impact, the spindle is given a partial rotation.
In the drawings Figure 1 is a perspective view of the improved apparatus.
Fig. 2 is an end elevation of the same.
Fig. 3 is a side elevation of the same.
The improved apparatus comprises a base 1 on which is mounted crank case 2 of a single cylinder two-cycle engine, the cylinder of which is shown at 3. The crank shaft 4 of the engine is provided with a cam 5, the periphery of which is stepped at 6, to provide a material radial drop. The base 1 is formed in line with the cam 5 with a sleeve 7 adapted to receive a spindle 8, the lower end of which is formed at 9 to receive a rock drill or other appropriate tool.
A shifting lever 10 is pivotally supported on a projection 11 from the crank case 2, the pivot being formed of a removable bolt 12 threaded into the projection. lThe upper end of the lever 10 is provided with a rollerk 13 adapted to bear upon the periphery of the cam 5, while the lower end of the lever is formed at 14 to engage any one of a series of elongated recesses 15 formed in the spindle 8. The wall of the sleeve bearing 7 is formed with an opening 16 to permit the passage therethrough of the operative end of the shifting lever.
The crank case 2'is preferably provided with diametrically opposed handles 17 whereby the apparatus as a whole may be moved from place to place or supported by an operator.
When in use as a rock drill, the weight of the apparatus as a whole causes the cam to bear upon the upper end of the spindle 8 so that at the rotation of the cam, which is in the direction of the arrow, Fig. 1, a series of blows are imparted to the spindle as the cam offset rides by the spindle. Following each impact the shifting lever 10 is turned on its pivot 12 by the action of the cam to therebv turn the spindle a distance equal to that between adjacent recesses.
The device is also adapted for use as a riveting machine, by substituting for the spindle 8, an appropriate riveting tool, and removing the shifting lever by disconnecting its pivot. The impact due to the action heretofore described will successfully upset a rivet.
Claims:
1. An apparatus of the class described comprising a motor, a cam member operated thereby, an operating spindle arranged in line with the cam and maintained in contact with the cam through the weight of the apparatus, the'cam being formed to im* part an impact to the spindle through such weight in each rotation of the cam.
2. An apparatus of the class described comprising a motor, a cam member open ated thereby, an operating spindle arranged in line with the cam and maintained in contact with the cam through the weight of the apparatus, the cam being formed tol impart an impact to the spindle through such weight in each rotation of the cam, and means operated by the cam for turning the spindle.
3. An apparatus of the class described comprising a motor, a cam member operated thereby, an operating spindle arranged in line with the cam and maintained in contact with the cam through the weight of the apparatus, the cam being formed to impart an impact to the spindle through such weight in each rotation of the cam, and a lever operated by the cam to engage and impartrotation to the spindle.
4. An apparatus of the class described comprising a motor, a cam driven thereby, a sleeve supported by the motor in line with the cam, a spindle mounted for free rotation and longitudinal movement in the sleeve, and a lever pivotally supported on the Inotor and operated by the cam to impart a rotation to the spindle.
5. An apparatus of the class described comprising a base, a gasolene engine mounted thereon and having a crank shaft, a cam mounted on the crank shaft, a sleeve supported by the base in line with the cam, a
spindle mounted in the sleeve and having a 10 dle, the movement of the lever by the cam 15 rotating the spindle.
In testimony whereof I aliX my signature.
