UNITED STATES PATENT OFFICE.
ERNST F. AUTENRIETI-I, OF NEIV YORK, ASSIGNOR TO THE GLEN COVE MACHINE COMPANY, (LIMITED,) OF BROOKLYN, NEIV YORK.
JOURNAL-BOX F OR PLANlNG-MACHINES.
SPECIFICATION forming part of Letters Patent No. 408,821, dated August 13, 1889.
Application filed March 2, 1889. Serial No. 301,733. (No model.)
To all whom it may concern:
Be it known that I, ERNST F. AUTENRIETH, of the city, county, and State of New York, have invented a certain new and useful Improvement in J ournal-Boxes for Planingdvlachines, of which the following is a specification.
My improvement relates particularly to the journal-boxes for the cutter-head shafts of wood-planin g m achines, and especially to horizontally-extending cutter-heads. These outter-heads rotate with great speed, and it is often a matter of difficulty to obtain such a lubrication of the journals as will prevent heating.
I will describe my improvement in detail, and then point out the novel features in a claim.
In the accompanying drawings, Figure 1 is a plan or top View of a cutter-head and its journals embodying my improvement. Fig. 2 is a vertical section through one of the journals. Fig. 3 is a plan of the lower portion of one of the journal-boxes and showing amodification.
Similar letters of reference designate corresponding parts in the several figures.
A designates a cutter-head mounted in a frame B in a well-known manner,which frame is secured upon the main frame of aplaningmachine. The cutter-head is mounted upon a shaft 0, which shaft is j ournaled in suitable bearings formed in journal-boxes D. Motion is imparted to the said shaftby pulleys a thereon.
In Fig. 2 I have illustrated one of the journal-boxes more clearly, and also the construc tion of the cutter-head shaft. The shaft is provided near its outer extremity with annular projections t, which projections are of greater diameter than the main portion of the shaft. The j ournal-boxes are provided internally and about midway their lengths with recesses c. WVithin these recesses the annular projections referred to are inclosed. They rotate in said recesses when the shaft is retated. Upon the upper sides of the journalboxes are inlet-passages cl, through which oil to lubricate the journals may be introduced into the recesses 0. Caps e are shown as closing the outer ends of said inlets. Oil introduced through the inlet-passage (Z into the re cesses c is agitated during the rotation of the shaft by the project-ions b on the shaft.
Near the ends of the journal-boxes are formed other recesses E.
F designates bushings for the journals. These bushings may be formed of Babbitt metal, or other suitable metal, as desired. In the example of my improvement shown in Fig. 2 said bushings are provided with longitudinally-extending grooves f. These grooves afford communication between the recesses c and E, along which oil from the recessescwill flow. In the lower portions of the journalboxes are passages g,which also communicate with both the recesses c and the recesses E. Oil having passed through the grooves f to the recesses E will be returned to the recesses 0 through the passages g.
In Fig. 3 I have shown that obliquely-extending recesses may be formed in the lower portions of the journal-boxes, in which pieces of felt or other suitable absorbent material may be arranged. When used, these pieces of felt or similar material assist in the lubri cation of the journals.
It will be seen that by my improvement I provide a Very efficacious means for lubricatin g rapidly-rotating journals, and also a means whereby there is a more or less constant circulation of oil through the journal-boxes and around the journals, whereby the journals are kept cool. I
\VhatI claim as my invention, and desire to secure by Letters Patent, is
The combination,with a shaft provided with projections of greater diameter than the shaft, of journal-boxes for said shaft provided with recesses for oil in which said projections rotate, and with other recesses near the ends of the journ al-boxes with which the recesses first named communicate, bushings within the journal-boxes and surrounding the journals, said bushings being provided with grooves for receiving the oil and supplyingit to the journals, substantially as specified.
