JOINTING AND TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,622, dated February 15, v1887. Application filed May 29, 1885. Serial No. 166,995. (No modali) To all whom t may concern:

Beit known that I, EDWARD K. YPATTEN, of Utica, in the county of Oneida and State of New York,have invented certain new and useful Improvements in .Iointing and Trimming Machines; and I do hereby declare that the following is a-full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referencer being had to the accompanying drawings, and to theletters of refer'en ce marked thereon, which form part of this specication.

My invention relates to that class of machines constructed for planing, trimming, jointing, and truing the sides, ends, edges, or angles of boxes, drawerslumber, and other articles where a true edge is required; and it consists in arotating head or heads carrying cutting-spurs and cutters mounted on independent shafts, in a feeding device for feeding the article to be operated on, and in other combinations and mechanical details hereinafter pointed out. Y

In the accompanying drawings similar letters of reference refer to corresponding parts throughout the several views.

Figure 1 is a section of the machine on line a: x, Fig. 2. Fig. 2 is a plan view of the machine. Fig. 3 is a left-hand end view of the machine. Fig. 4 is a vertical section on line y y, Fig. 1. Fig. 5 is a side view of a feeding device and a section of the frame. Fig. 6 isa plan view of the same. Fig. 7 is an end view of the feeding device and the section of the frame. Fig. 8 is a front view of the rotating head, showing the location and construction of the spurs and cutters in the face of the head. Fig. 9 is a section view of the head and a side view of the pulley, the` broken lines indicating a section of the upright. Fig.v 10 is a view of the cutting-spur. Fig. 11 is a side view of a cutter. Fig. l2 is an end view of the cutting-spur and a section of the head, exposing the retaining-bolt for securing the cuttingspur to the head. Fig. 13 is a side view of the retaining-bolt, and Fig. 14 is a top view of the same.

Having described my invention by reference to the figures represented in the accompanying drawings, I will nonr proceed to describe the same by reference to the letters marked thereon.

The machine represented in the drawings is constructed for truing, trimming, and smoothing opposite ends or sides of drawers, boxes, or other lumber. I do not, however, intend to limit myself to the use to which this machine may be applied, nor to the man ner of constructing the same, as it is obvious that the rotating head or heads, carrying suitable spurs and cutters, may be used in a variety of ways not illustrated for jointing, truing, and planing sides or angles of lumber where a plane or true edge is required. and maybe accomplished by a single or by double heads, as the case may require.

For trimming, planing, matching, smoothing, and truing the opposite surfaces of articles, I provide two heads mounted, preferably, on independent shafts journaled in stationary or movable uprights for supporting and carrying the rotating head. In the draw ings the heads are mounted to be rotated vertically, and are driven by belt-s running on Suitable pulleys driven from the main line of shafting.

The working parts of the machine are shown mounted on frame A consisting of four legs united by suitable cross-ties, as shown, but which may be of any other suitable and convenient construction.

B and B represent heads in which are secured spurs.

b b b b represent four spurs or cutters, the spur ends forming a cutting-surface and extending beyond the periphery of the head for forming a cuttingsurface in line with the face of the spurs. Thesespurs are let into the face of the head by dovetailed grooves b b b b. One or more of these spurs may be used. The spurs are fitted into the grooves and held by bolts b2. The projecting ends of the spurs should be brought to a sharp cutting-edge.

b4 represents cutters set in the face of the rotating heads, substantially in line with the spurs and extending beyond the periphery of the head to a point substantially in the same circle with the projecting ends of the spurs. These cutters are provided with cuttingedges, as indicated in Fig. 11, and are set in the head substantially at right angles with the spurs IOO for cutting and cleaning the material cut and f trimmed by the spurs.

The cutters are held in grooves in the hcad by bolts substantially like that shown in. Fig. l5. In the drawings the heads are shown circular. While this form is preferable, those having angles may be used, the spurs and cutters being set in the projecting angles ofthe head. These heads provided with the spurs and critters are mounted ou shafts c a and are held rigidly thereto by nuts or keys, or botlnand are mountedin journals c a ac in the upper ends of upright-s D D,and are driven by pulieys a? arigidly held on the shafts by belts running on drum K, journaled in the frame connected with drivingpulley P, which is connected with the mainline ofshafting, for imparting a rotating motion to the heads carrying the spurs and cutters.

To adjust the heads to different-sized arti cles to be operated ou I provide movable uprights D D, which are mounted on rods e e, which pass through the uprights at c' e e' c', which siide on the rods, which are rigidly held at their extremities e c3 c c3 in the frame. In the dr. wings the right-hand upright', D, issecured rigidly in position on the supportingrods by set-screws e* e, the left-hand upright being movable to secure the proper adjustment by adjustingscrew e5, one end working in suitable bearings in the righthand upright and the opposite end in the frame at e", and is operated by hand wheel e? for turning the screwthreads in the left-hand upright for horizont-ally moving the same to secure accurate adjustment.

I disclaim the use and construction of a trimming-machine provided with four raised ways, with a movable carriage mounted thereon, two uprights in which are mounted to be operated in parallel lines, two circular saws, with a right and left hand screw for moving the saws to or from a common center in the same right line, the said carriage moving between the saws for feeding the article to be operated thereon.

For feeding the article to be operated on between heads carrying the spurs and cutters for simultaneously operating upon opposite angles, I provide tracks ff,with cross-grooves ff, (shown in Fig. 5,) let into the same on the under side thereof. These grooves fit projecting danges f, Fig. 2, on the upper surface of the frame. In the drawings the righthand track is held rigid by set screw f 3. The left-hand track is attached to the movable upright by braces fj and moves therewith. On the upper surface of the tracks are projecting flanges f 5 f 5. Itis obvious that either or both of these might be secured to the uprights, if so desired. On the upper surfaces of these tracks are provided carriers Gr G, on the under side of which is a groove to tit the projecting Bauges f 5 f 5, for securing accurate movement. On the rear of each carrier is a projecting surface, g, (shown in Fig. 5,) asimilar one being provided on each, against which the article to be operated on is driven by screws g g', working in bearings g2 y, operated by hand-wheelg3.

Operation: The operator sets the rotating heads to suit the article to be operated on. The article is then placed on the carriers and crowded against projections g g, and rigidly clamped by turning the handwheelsg3g The operator then crowds the article and carriers forward,which are moved in accurate liuc on the flanges on the upper surface of' the track until the article is passed between the rotating heads carrying the spurs and cutters. 'Ihe carriage and article are then returned and the article removed from the machine.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In amachine for planing,trimming, jointing,and truing the sides, ends, edges, or angles of boxes, drawers, lumber, and other articles where two edges are required lto be parallel with each other, the combination of two heads mounted in two uprights and constructed to be rotated in the same direction in parallel planes, each head carrying one or more cut ting spurs,and one or more clearingcutters,ar ranged substantially as described,f`or the purposes stated.
