MINING-MACHINE.
Specification of Letters Patent.
Patented Jan. 28, 1913.
Application filed February 9, 1911. Serial No. 607,598.
To all whom it may concern:
Be it known that we, PATRICK J. KELLEY and JAMES S. KELLEY, citizens of the United States, residing at Pana, in the county of Christian and State of Illinois, have invented certain new and useful Improve ments in Mining-Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in mining machines.
One object of the invention is to provide a mining machine having an improved construction and arrangement of hand operated drill actuating mechanism whereby the drill is rapidly reciprocated.
Another object is to provide a mining ma chine of this character which will. be simple, strong and durable in construction, efficient in operation and well adapted to the pur-' pose for which itis designed.
With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out. in the appended claim.
In the accompanying drawings: Figure l is a side view of our improved mining machine; Fig. 2 is a plan view of the same with the casing removed; Fig. 3 is a vertical longitudinal section on the line 3-3 of Fig. 2; Fig. 4; is a cross sectional view on the line et4 of Fig. 2; Fig. 5 is a detail perspective view of the drill supporting and reciprocating bar.
Referring more particularly to the drawings, 1 denotes the supporting frame of the machine, said frame being preferably of rec tangular form and open on its lower side and closed on its upper side by a hinged cover 2 having on one end an upwardly projecting hood 3 to accommodate the working parts of the machine. Slidably mounted in the lower portion of the frame 1 is a drill reciprocating bar 4 the forward end of which projects through and is slidably mounted in a bushing 5 arranged in the forward end of the frame as shown. The rear or inner portion of the bar 4 is slidably sup ported in a combined supporting bar and stop 6 arranged across the frame as shown.
The inner end of the bar t is bent downwardly at right angles to form a stop lug 7 which, when the drill operating rod is pro-v jected to its greatest extent, will engage the cross bar 6 and thus limit the forward movement of the bar. Ata suitable point the bar 4. is bent to form a downwardly projecting recess or offset 8 the "ends of which form shoulders 9 with one of which is adapted to be engaged a bar retracting mechanism hereinafter described. Arranged on the bar 4: near the forward end of the ofiset 8 is a cross head 10 said cross head being preferably adjustably secured to the bar by a set screw 11. On the opposite ends of the cross head 10 are formed hooks 12 with which are engaged the inner ends of coiled drill projecting springs 13 the forward ends of which are connected to eye bolts 1 arranged in the forward end of the frame 1 as shown. The pressure of the springs 13 when thus arranged is applied to forcibly project the bar 4 and the drill when the latter are retracted by the retracting mechanism to be described. 011 the outer end of the bar is arranged a chuck or socket 15 by means of which the drill 16 is operatively connected to the bar.
Our improved drill'ret acting mechanism comprises a tappet wheel 17 consisting of parallel circular plates 18 which are spaced 7 apart and fixedly mounted on an operating shaft 19 j ournaled in suitable bearings in the sides of the frame 1. The plates 18 are bolted together at intervals by connecting bolts 20 on which are arranged spacing sleeves 21 which space the plates a suitable distance apart. The bolts 20 and sleeves 21 form the tappets of the wheel and are adapted to be brought into successive engagement with the rear shoulder 9 of the recess 8 in the bar 1 whereby the latter is successively retracted against the pressure of the springs 13. The portion of the bar 4; engaged by the tappets of the wheel projects upwardly between the plates 18 of the tappet wheel as shown. By constructing the tappet wheel 17 in the manner described, the shaft 19 is limited in movement in a transverse direction, the circular plates 18 forming the op posite sides of said wheel being adapt-ed for contact with the opposite flat sides of the drill shaft 4 adjacent to the depressed portion 8 thereof, whereby, the operating gearing is held in alinement.
()n the shaft 19 of the tappet wheel is fixedly mounted a sprocket gear 22 which is connected by a sprocket chain 23 to a sprocket pinion 24 on a drive shaft 25 which is revolubly mounted in suitable bearings in the sides of the frame 1 near the rear end thereof as shown. On the shaft 25 is also fixedly mounted a sprocket gear 26 which is connected by a sprocket chain 27 to a sprocket pinion 28 on the fly wheel shaft 29 which is revolubly mounted in suitable bearings in the sides of the frame near the central portion thereof as shown. On the projecting outer ends of the fly wheel shaft 29 are fixedly mounted, fly wheels 30. The momentum of said wheels 30 when imparted to the drive shaft will assist in keeping up the steady. motion of said shaft.
Any suitable means may be applied to the drive shaft 25 for operating the same said means being here shown and is preferably in the form of a ratchet lever 31 having on its outer end a crank handle 32 whereby a forward movement may be imparted to the operating mechanism. Any slight stopping or irregularity in the movement of the lever will not interfere with the steady or continuous movement of the driving mechanism through the force imparted thereto from the momentum of the fly wheels. The frame 1 is .preferably supported upon small supporting wheels or rollers 33 which are mounted on a shaft suitably secured to the lower edges of the frame 1 midway between the ends. thereof as shown. By thus supporting the frame the machine may be readily moved from one place to another.
In practice the springs 13 are of sufficient strength when fully extended to impart the desired projecting force to the drill 16 for ordinary and practical purposes, and in this instance the desired tension of the springs is obtained by moving the cross head 10 to its full limit of adjustment. and against the stop formed by the offset 8 of the bar 4:, whereby the machine can be successfully operated by an inexperienced person.
From the foregoing description taken in connection with the accompanying drawings, the construction andv operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claim.
Having thus described our invention what we claim is:
A mining machine comprising a suitable frame, a transverse supporting and stop bar secured to the opposite sides of the same, a drill operatingrod slidably mounted in the forward end of the frame and bar, and having a depressed portion forming two oppositely disposed shoulders, an operating shaft mounted in the opposite sides of the frame, a tappet wheel mounted upon said shaft and centrally positioned upon the same, circular plates forming the opposite sides of said wheel and adapted for contact with the drill rod, rollers mounted. between said plates for supporting the same and adapted for contact with the rear shoulder formed by the depression in the drill rod, a depending stop lug forming the terminal end of the rod and adapted for contact with the transverse bar, a cross head adjustably secured upon the drill rod and adapted to be secured against the forward shoulder formed by the depressed portion thereof, equalizing coiled springs detachably connecting the opposite ends of the cross head to the forward end of the frame, said springs being in parallel relation with one another and with the drill rod, and means for imparting rotation to the operating shaft.
In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
