UNITED STATES PATENT OFFICE.
MILO'A. BAKER, OF LOS ANGELES, CALIFORNIA.
MACHINE FOR TRUING THE ENDS OF METALLIC PIPES OR OTHER OBJECTS.
To all whom it may concern:
Be itknown that I, MILo A. BAKER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and tate of California, have invented a new and useful Machine for Truing the Ends of Metallic Pipes or other Objects, of which the following is a specification.
This invention relates to a machine for truing the ends of metallic pipes so that when they are placed one against the other they will fit properly and form a straight line of pipe.
One object of the invention is to provide a simple machine for the above stated purpose.
Another object of the invention is to provide a machine for the stated purpose which will equalize the wear on the grinding wheels so as to maintain a flat even face thereon.
Another object of the invention is to provide for adjustment of the machine to different sizes of pipes.
The accompanying drawings illustrate the invention.
Figure 1 is a plan of a form of the machine wherein the grinding wheel is moved transversely by automatic means so as to continually present different parts of its face for abrasive action. Fig. 2 is a side elevation thereof. Fig. 3 is a side elevation of the rack and pinion used in the machine. Fig. 4L is an end elevation. Fig. 5 is a plan of a form of the machine wherein the work to be ground is moved transversely to the grinding surface and wherein means are provided for grinding two pieces of work at once. Fig. 6 is an end elevation of the form of the machine shown in Fig. 5, and
Fig. 7' is a side elevation of a portion thereof.
Referring to Figs. 1 to 4, the machine comprises a frame or base 1; a slide 2 mounted to move transversely on rails or ways 3 on said frame and carrying the grinding means 4, whose arbor 5 is journaled in hearings on said slide 2; and a bracket 6 mounted to move vertically on the base 1 and carrying the pipe cradle or work support 7. The bracket 6 is guided by vertical ways or rails 8 on the base 1 and is vertically supported by a screw 9 supported at its lower end in an extension 10 of base 1 and engaging a cross-piece 11 on said bracket, said screw having an operating Specification of Letters Patent.
Application filed October 5, 1908.
Patented March so, 1909.
Serial No. 456,344.
For the equalization of wear on the grinding face it is necessary that there should be relative transverse movement of the grinding wheel and of the pipe to be ground. This may be obtained either by moving the wheel support transversely as above described or by moving the work support or cradle transversely, as with the machines shown in Figs. 5 to 7. In said figures the grinding means are supported directly on the frame 1, said means comprising two oppositely facing grinding wheels 34; tied by a shaft 35 mounted in brackets on the standard 32 which is secured to or extends upwardly from the frame 1. Said shaft 35 is provided with a driving pulley 41 for r tating the shaft and the grinding wheels 34. The cradle supports or carriers 36 are in this case mounted to move transversely of the frame 1, said carriers sliding on ways 33 and carrying the cradle means 37 for supporting the pipes to be ground. Each cradle carrier 36 is connected by a link 42 with a crank wheel 43, said crank wheel also being formed as a bevel gear to engage a driving bevel pinion n on a shaft 4&5 journaled in bearings on the frame 1 and provided with a driving pulley 46, whereby the said crank wheels are rotated and the cradle car ie "s are given a to and fro movement transversely of the frame and of the axis of rotation of the grinding wheels. The result is that the wear is equalized over the face of the wheels as above described. in this form of the machine two pipes can be ground or trued' simultaneously by the action of the two wheels 4.
What I claim is 1*- 1. A machine for grinding pipes or other objects comprising a frame, a grinding wheel having an extended flat grinding face, means for rotating said grinding wheel, a supporting means for said grinding wheel, supporting means for the pipe to be ground, means for automatically causing relative motion of the said two supporting means in a direction transverse to the axis of rotation of the grinding wheel, and means for relative vertical adjustment of the said two supporting means.
2. A machine for grinding pipes or other objects comprising a frame, a grinding wheel having an extended flat grinding face, means for rotating said grinding wheel, a support for said grinding wheel, a support for the pipe to be ground, one of said supports being movable on said frame in a direction transverse to the axis of rotation of the grinding wheel, a crank means connected to said movable support to cause to and fro motion thereof, driving means for said crank means, and manually operated means for relative vertical adjustment of the supports for the grinding wheel and for the pipe.
3. A machine for grinding pipes or other objects comprising a frame, a grinding wheel provided with an extended flat grinding face, means for rotating the grinding wheel, a support for said grinding wheel, a support for the pipe to be ground, one of said supports being movable on said frame transverse to the axis of rotation of the grinding wheel, a shaft rotatably mounted on the frame, a crank connection between said shaft and the aforesaid transverse movable support, means for driving said shaft, and manually operated means for relative vertical adjustment of the supports for the grinding wheel and for. the pipe.
i. A machine for grinding the ends of pipes or other objects comprising a holder for the pipe, a grinding wheel having an extended flat face presented toward said holder, means for rotating said grinding wheel, means for causing relative movement of the grinding wheel. and pipe holder in a direction transverse to the axis of rotation of the grinding wheel, and means for rela tive verticaladjustment of the pipe holder and the grinding wheel.
A machine for grinding the ends of pipes or other objects comprising a holder for the pipe, a grinding wheel having an extended flat face presented toward said holder, means for rotating said grinding wheel, means for causing relative movement of the grinding wheel and pipe holder in a direction transverse to the axis of rotation of the grinding wheel, means for relative longitudinal. adjustment of the pipe holder and the grinding wheel, and means for relative vertical adjustment of the grinding wheel and pipe holder.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 28th day of September 1908.
MILQ A. BAKER.
In presence of FREDERICK G. LYON, FRANK L. A. GRAHAM.
