JOlNTlNG ATTACHMENT FOR PLANING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 295,101, dated March 11, 1884.
Application filed November 1, 1882. (No model.) 7
I jointer embodying my invention; Fig. 2, an
end elevation of the jointing attachment in position on the planer; Fig. 3, a broken top view of the driving'gear to the jointer; Fig. 4, a
' cutter-head to the jointer removed from the machine; Fig. 5, an inverted view of the cutterhead; Fig. 6, an elevation of the drivewheel attachment to the j ointer removed from the planer.
, The object of the present invention is to provide suitable mechanism, which, attached to the Benjamin wood-planer or other surfacing machines, will joint the material as it is being pla'ned. In this regard I do not claim thatit is new to joint lumber at the time it is being planed, as that has before been done by machines of different construction; but I claim that the novel construction of the gearing and devices placed above the planer has not before I i do the jointing, and also the mechanism which been used.
Among the advantages attained by placing the jointing attachment above the bed of the machine are a less complication of machinery in a body below the bed, where the chips re moved from the lumber clog the working parts by their gravity, the distribution of the mechanism in such a manner that the jointing attachment can be put in and out of gear readily when the surfacing is being done, and the construct-ion much simplitied,'while at the same time the attachment can be removed without taking apart the main frame of the machine. This latter attainment is important, inasmuch as repairs can be made on the jointing attachment while the mechanism of the surfacer is undisturbed and is free to be used. In these regards the attachment is adistinctive feature in its construction, as compared with patents to G. R. Thomphins on June 1875, and to Franks and Spire on December 28, 1875.
The nature of the invention, in brief, consists of an adjustable drivewheel attachment joint all of the ordinary widths an d thicknesses of lumber.
A B G D I) represent a welllrnown Benjamin wood planer or surfacer, to-which my device is attached.
E represents one of the standards which support the drive-shaft K to the jointer. Cast solid to or otherwise affixed to the standards E, each, are two bearings, J I, to support the box-hangers H, screws 1) being formed on the lower ends of the hangers, to receive the adjustingnuts a, by means of which the hangers are raised or lowered as required. The boxes Z are pivoted to the hangers E, as shown at a, Figs. 1 and 2, so that when the standardsE are attached to the frame A of the planer the boxes Z will adjust themselves to the bearing of the shaft K. This construction, however, is simply a matter of construction rather than invention; but it is a convenient means for adjusting the drive-shaft K and its -boXesthat is, either end of theshaft may be raised or lowered, and the boxes will be selfadjusting.
F O F 0 represent standards which are respectively attached to the sides of the planerframe A, to support the cutter-heads N,which drives them and adjusts them to joint differ ent widths of stuff. Abar, V, is made to connect the top portions of the standards F 0, so as to hold the parts, respectively, in position and prevent vibration, also to provide a suit able guide for the upper ends of the box-standards Y as they are moved in or out. That this may be done, the bolts r, which hold the standards Y to the bar V, pass through the slot, and by loosening the nuts on the bolts the standards may be moved. A lower bar, f, is bolted fast to the standards F O, and on its face is formed a dovetail, 3, on which the lower ends of the box-standards Y are fitted to slide in or out, as the case may require. The means for adjusting the box-standards consist of screw-nuts T T, which pass through nuts on the standards Y, and have shoulders butting against the ends of the bar f and against its middle part, so that turning the screws to the right will set the standards Y farther apart, and turning them to the leftand an adjustable jointing device suited to will set them together. There being two independent screws, the standards Y may be separately adjusted. The shafts W of the cutterheads N run in the boxes-B It on the boxa 5 standard Y, and are driven by belts L L, coming from drive-wheels G G and passing round pulleys I. The cutter-heads N are similar to those in common use and are placed with reference to the rollers D D. D D of the planer IO so as to joint the edge of the board or stuff during the time it is being faced. The belt from the motive power passes over pulley M. By this means the ordinary surface-planer may be provided with a simple and effective 1 5 jointer Without any change in the construction thereof.
Having thus described my invention, what I claim and desire to secure by Letters Patent,
In a jointing attachment to Wood-planing 2o machines, the standards E and F 0, attached to the top of the planer-frame, the standards E,
1 to support the drive-shaft K, and the stand ards F O, to support the jointing devices, consisting in the combination of the cutter-heads 2 5 i supported by adjustable box-standards Y, hav- 1 ing sliding bearings in the bars Vf, as and for tht purpose specified.
