HENRY H. SHEIP, OF PHILADELPHIA, PENNSYLVANIA.

WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,279, dated September 1, 1885.

Application filed June 2, 1885.

To all whom it may concern.-

Be it known that I, HENRY H. SHEIP, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certzn'n new and useful Improvements in Wood-VVorking" Machines, of which the following is aspecification.

My invention is a wood-working machine adapted for use in cutting different materials to different forms, but specially intended for producing and finishing thin boards or veneers used in box-making; and my invention 0011- sists in providing a machine with two vertical cutter-shafts, one revolving in fixed bearings and the other in bearings connected to a guided frame, and with a carriage for holding the material provided with a clamp for securing the said material, and with an adjustable guide for guiding the said carriage in respect to the cutter, all as described hereinafter, and illustrated in the accompanying drawings, in Which- Figure 1 is an end elevation of my improved wood-working machine. Fig. 2 is a front elevation in part section. Fig. 3 is a plan View, the clamp-carriage being removed.

L is the standard or support of the machine, to brackets upon which are secured longitudinal parallel cross-bars N N, the latter being connected at one end by a connecting bar or yoke, N.

To the cross-bars N N, near the yoke N, are secured the bearings K K of a vertical cutter-shaft, G, upon the upper end of which is mounted a cutter-head, D, provided with the usual detachable cutter-platcs,a, and upon the shaft between the cross-bars is secured a band-pulley, I, to which a band passes from any suitable driving-wheel.

In the cross-bars NNare formed longitudinal undercut grooves or channels to receive and guide a sliding frame, J, upon which are mounted the bearings K K of a vertical cutter-shaft, F, carrying a cutter-head and bandpulley, and driven by abelt from an adjacent drivingpulley in a direction the reverse of that imparted to the shaft G.

The channeled bars N N constitute the guides of the frame J, which may be adjusted between said guides to carry the cutter-head of the shaft F to or from the cutter-head of the (No model.)

shaft G, and in order to move the frame J, and also secure it in any position to which it is set, I use a screw-shaft, M, turning in a bearing on the yoke N, and extending through a nut projection, e, at the back of the frame, the screw-shaft being provided with a handwheel, 0, for facilitating its manipulation.

As a support for the material to be operated upon by the cutters, I use a platform or table, H, which is secured to the top of the standard L, and which contains alongitudinal slot for the passage of the shaft F, and permits the latter to be adjusted to and from the shaft G, the frame J carrying the usual guards, which are supported in proper position in relation to the cutter-head above the table, and slide with the shaft F. The guards are also arranged in suitable proximity to the cutterhead carried by the shaft G.

In order to properly guide and secure the material which is to be operated upon by the cutters, I use a combined carrier and clamp, B, the same consisting of a base, (1, standards d (1, arm f, hinged to the standard d, and constituting part of a swinging frame, in which slide vertically clamp-bars S S, provided with clamp-heads s at the lower ends, and with shoulders t, against which bear springs a. A catch, is hung to the arm f, to engage with a pin, 71, upon the frame of the clamp.

The lower bar, d, of the clamping-carrier is dovetailed and adapted to a dovetailed groove, y, in an adjustable guide, E, which extends over the table at right angles to the slot at, and is provided with a guiding-head, h,which bears against one edge of the table, and with lips m m, and set-screws a n,which may be withdrawn to permit the guide to be moved to any suitable position upon the table, and then can be set against the latter to secure the guide in its position.

The clamp-carrier slides longitudinally in the guide E back and forth between the cutter-heads, and serves as a means of holding and guiding the material to be cutfor instance, a series of thin boards or veneers, which are arranged upon the bar d of the carrier after elevating the arm f, and are then confined by bringing the arm down to a horizontal position, as shown in Fig. 1, so as to cause the clamp-bars s to bear upon the same under the pressure of the springs a, so that all the pieces or strips are brought firmly together and securely retained in position, after which the carrier is moved forward to carry the material between the cutter-heads and subject the opposite sides to the action of the cutters, which rapidly reduce all the pieces to a uniform width, and impart straight and smooth edges to the same, the clamp holding the material so firmly that it cannot be drawn therefrom by the action of the cutters. I have found it best to impart a high rate of speed to the cutter-shaftsthat is, a speed of about four thousand revolutions a minute, which I have found to result in very rapid operations,

and in the reduction of the material without breaking or tearing the same, so as to produce smooth and nicely-finished edges.

By turning the screw M the cutters may be set to any desired distance apart, and the guide E may be readily moved and secured in any desired position upon the table, so as to guide the material in relation to either or both of the cutters.

To regulate the depth of the cut a gageplate, a, is carried by a slide, of, resting upon the table and adjustable thereon, and provided with a securing-screw, n", having a head adapted to a dovetailed slot, 5, in the table,

and passing through a hand-nut, n, whereby it may be wedged in the slot to secure the parts after adjustment.

It' will be obvious that the cutterheads' and cutters may be of any suitable form, according to the character of the work to be done, and that the spring clamp may be differently constructed from that shownfor instance, the pivoted arm f may carry a series of rubber bearing-pieces or a series of spiral springs at the under side.

In order to compensate for wear and guide the carriage in a perfectly-straight line, the guide E may be provided with a beveledged strip, w, adapted to bear against one side of the dovetailed bar d, and provided with slots 3 for the passage of screw-bolts o, by means of which the strip may be set close to the side of the bar and then secured to the base of the guide. Y

By means of the above-described machine, which is especially adapted for use in the manufacture of cigar-boxes, I am enabled to firmly clamp the thin strips of wood together, even when the stuff is warped and irregular, and to rapidly reduce the same without the use of skilled labor, and with the expenditure of comparatively a small amount of power.

Without limiting myself to the precise construction and arrangement of parts shown, I claim- 1. The combination, with the standard or support of a woodworking machine, of fixed bearings supported thereby, a vertical'shaft turning in said bearings and carrying a cutter head, guides supported by the standard, a frame sliding in said guides, bearings supported by the frame, a second shaft supporting a cutter-head turning in the latter bearings, anda table or platform slotted for the passage of the movable shaft supported by the frame, substantially as and for the purpose described. 7

2. The combination, in awood-working machine, of a table provided with a guideway, a cutter-head supported above the table, a carrier adjustable in said guideway and provided with a pivoted arm carrying a series of yielding clamps, and means, substantially as described, for locking the arm in place when brought upon the material, as and for the purpose set forth.

3. The combination of,the cutter-heads and movable and fixed shafts, table, guide adj ustable upon the said table between the cutterheads, carrier movable upon said guide, and a clamp for securing the material in said carrier, substantially as and for the purpose described.

4. The combination, in awoodworking machine, of a vertical shaft revolving in fixed bearings andcarrying a cutter, aslotted table, an adjustable frame, a second vertical shaft revolving in bearings upon the frame and carrying the cutter, a guide secured adjustably upon the table, and a carrier sliding in said guide and constructed to receive and retain the material to be cut, substantially as de scribed.

5. The combination, with the frame of the carrier, of a pivoted arm, device, substantially as described, for securing said arm in place when brought upon the material, and sliding rods supported by said arm and provided with heads at their lower ends and with shoulders t, and springs bearing upon said shoulders, substantially as and for the pur pose described.

Intestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY H. sI-IEIP.
