REVERSIBLE B EVEL-SHAPER, SAW', AND BORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 379,930, dated March 2'7, 1888.

Application filed March 14, 1887.

Kansas, have invented a Reversible Bevel- Shaper, Saw, and Boring-Machine, of which the followlng'is a specification.

My invention is a new woodworking machine, in which the material to be worked is operated upon by means of suitable cutters attached to a revolving arbor; and the objects of my improvements are, first, to provide an trated in the arbor arranged to have a rotary, reversible, radial, and vertical movement; second, to afford facilities for properly adjusting the arbor to work at any angle from horizontal to vertical; third, to apply the belting so that it may be retained on the pulleys at a proper tension and be automatically adjusted to the varying posltions and angle of the arbor; fourth, to secure a means of adjusting the slot or openlng 1n the table-top with reference to saws 0r cutters on thearbor, and, fifth, to construct the tabletop in such a manner that part of it may be used as a boring-table with lateral and vertical motion in conjunction with a revolvlng arbor for boring and routing. I attam these objects by the mechanism illusaccompanying drawings, of which- Figure 1 is a top view of the machine as it I appears with table-top removed, showing out sections of important parts. Fig. 2 is a rightside elevation with part of frame broken away, showing mechanism for manipulating the arbor and the method of belting over binder-pulleys. Fig. 3 is a plan with table-top removed, showing arrangement of mechanism for operating arbor 13. Fig. 4 is a section on line A B, Fig. 3, showing driving-pulley 10, binder-pulleys 28 29, and means for vertically adjusting arbor 13. Fig. 5 is a front elevation showing mechanism for radially adjusting arbor 13. Fig. 6 is a front elevation showing split bearing 14 on apron 15 and mechanism for vertically adjusting same. Fig. 7 is a rear elevation of driving-pulley 10, binder-pulleys 28 29, and means for automatically adjusting the belts. Fig. Sis a plan of table- tops 41 and 42, showing in dotted lines the recess for sliding pieces 54 and 55. Fig. 9 is a left-side elevation showing vertical adjustment of apron versing lever and collars 7.

and has a vertical motion thereon through the on sliding rack 34.

43 and lateral adjustment of table 42 on slides 45 and 46.. Fig. 10 is a group of views show-- ing construction of guide 58 and slide 60 in claim 6. v The frame is constructed as shown by 1 and 2, Figs. 1, 2, 3, and 4. In hearings on frame 2 turns the shaft 3, carrying cone friction-pulleys 4 and 5, the -flat driving-pulley 6, andre- The shaft 8, run-' ning inbearings on frames 1 and 2, carrying cone friction-pulley 9 and grooved driving pulley 10, is caused to revolve in opposite directions by cone-pulleys 4 and 5 being brought in frictional contact with opposite sides of cone-pulley 9 by means of reversing lever and collars 7 on shaft 3, working in thrust-block:

- The apron 15 is adapted to slide on frame 1,

8o medium of hand-wheel 20, miter-gears 21 22," and screw-rod 23, working in threaded lug 24 on connecting-bar 25, so that by turning hand-- wheel 20 a vertical motion is imparted to arbor l 13. The apron 15 is adjusted to take up lost motion by set-screws 27, Figs. 2 and 4.

The grooved binderpulleys 28 29 are fastened to spindles turning in-bearings on pivoted: arms 30 31, Figs. 2 and 3, said arms having a journal or pivot fornied'on their lower ends, and which swivel in suitable bearings, 32 33, This sliding rack is adapted to a slide, 35, on the inside of frame 1, and is moved horizontally thereon by a pinion, 36, gearing into rack 34. Said pinion is secured to a shaft turning in a bearing, 37, on frame 1, and having fastened on its outer end a rope-wheel, 38, carrying a weight, 39, Figs} 3 and 5.

Round belts 40, fitting into suitable grooves in driving pulley 10, passing over grooved binder-pulleys 28 29v and around the grooved pulley on arbor 13 and driven by the reversemotion friction pulley 9, cause the arbor 13 ICO to revolve in either direction, the belts being retained in position and proper tension through the medium of the automatically-adjusting binder-pulleys 28 29, Figs. 2 and 3.

The tabletop 41 42 is made in two pieces, the largest piece, 41, being bolted rigidly to frames 1 and 2, the sliding piece 42 having a vertical and lateral movement.

The apron 43 is fitted to vertical ways 44 on frame 1, and is provided with horizontal bracketslides 46, on which the movable table-top 42 is secured by gibs 47 48. Said apron 43 is moved vertically by hand-wheel 49, secured to a shaft on which is fastened a miter-gear, 50, meshing into a like miter-gear, 51, on screwrod 52, working through threaded lug 53 on frame 1, Figs. 1 and 3.

In the table-tops 41 42 is a recess extending across both sections, into which is fitted corresponding sliding pieces, 54, that can be fastened in said recesses in any required lateral position by bolts and thumb-nuts, as 56. The sliding pieces 54 are separated to receive between them a third sliding piece, 55, having a circular holein it, through which projects the shilper-spindle 57 on arbor'13, when used for shaping. All of sliding pieces 5455 may be moved laterally across the tables 41 42, thus affording an adjustable slot in table for square or bevel sawing, dadoing, &c., and an adjustable circular opening, 55, to accommodate arbor 13 when used as a vertical or bevel sh aper, Fig. 3.

The guide 58, Figs. 3 and 4, is furnished with two pins on its under side and lug on its end, and is placed on tables 41, the pins fitting into two rows of holes bored in the table to receive them, thus preventing any side motion of guide 58, which is clamped down by thumbscrew 59, as shown, Figs. 3 and 4. It is used in connection with slide for crosscutting, mitering, dadoing, &c. The cut-off slide 60, the fence of which is made to swivel, is adapted to guide 58 and table 41, on which it slides.

The ripping gage 61 has an arm sliding through frame 62, in which it is fastened by thumb-screw 63. Said frame is also provided on the under side with two pins like those on guide 58 and fitting into the same holes in table 41 42, and may be used on either side of the saw.

I am aware that prior to my invention there have been made reversible shaping-machines in which friction cone-pulleys have been used, also a ripping-gage and cut-off slide somewhat similar to those herein described. I therefore do not claim these as my invention; but I What I do claim as my invention, and desire to secure by Letters Patent, is-
