H. SCHEVENELL AND R. S. SGHEVENELL, OF ATHENS, GEORGIA.

MACHINE FOR CUTTING ORNAIVIENTAL MOLDINGS.

Specification of Letters Patent No.

To all 'whom t may concern Be it known that we, H. SCHEVENELL and R. S. SCHEVENELL, of Athens, in the county of Clark and State of Georgia, have invented a new and Improved Machine for Cutting Ornamental food Moldings; and We do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a longitudinal vertical section of our improvement. (m) Fig. 3 showing the plane of sect-ion. Fig. 2, is a transverse vertical section of ditto, (y) Fig. l, showing t-he plane of section. Fig. 3, is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of our invention consists in the combination of rotary patterns, reciprocating gate or slide with cutters attached, and inclined planes or wedges placed underneath the gate, the above parts being arranged and operating as will be hereafter fully shown and described.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

A, represents the base of the machine to the sides of which metallic plates (a) (a) are att-ached. The upper parts of the plates have projections on them at right angles with the plates in order to form guides (b) (Z9) which it in grooves (c) (c) in a carriage B, see Fig. 2. The plates (a) (a) and guides (In) (b) may be constructed of cast iron, and cast in one piece.

Underneath the carriage B, there is attached a longitudinal rack C, in which a pinion D, on a transverse shaft E, gears, said shaft having its bearings in the plates (a) To each plate (a) there is attached an upright (d). Between the two uprights (d) (d) a gate or slide F, is fitted; the uprights having guides (e) on their inner edges which t in grooves in the ends of the gate or slide. The upper ends of the uprights are connected by a cross piece (f). To the upper end of the gate or slide F, there is attached a rod G, which passes through the center of the cross piece The upper end of this rod has a screwthread cut upon it, on which a nut I-I, is fitted, the nut being above the cross piece.

Around the rod G, and between the under surface of the cross piece and the gate or slide F, there is placed a spiral spring I. To the front side of the gate or slide F, there is attached a plate J, the ends of which project a short distance beyond the uprights (Irl), (d). To this plate J, the cutters K, K, are attached, two are represented in the drawings but more or less may be used. The cutting edges of the cutters are made of a form corresponding to the form intended to be given the moldings, see Fig. 2. To each end of the shaft E, there is hung a pattern L. These patterns are constructed by cutting indentations of proper length into the peripheries of circular plates so as to form a series of curved projections on the peripheries of the plates. The form of the peripheries of the plates may be varied however so as to form differentI styles of moldings. On the upper surfaces of the guides (b) (In) there are placed inclined planes or wedges M, M. These inclined planes or wedges are directly underneath the plate J, at each side of the carriage B. Each end of the carriage B, has a projection (g) upon it as shown in Fig. 3.

The strips designated by N, to be operated upon are clamped upon the carriage B, directly underneath the cutters K, K, the spring I, presses the edges of the cutters K, upon the strips M, and the ends of the plate J, upon the peripheries of the patterns L, L. Motion being given the shaft E, the carriage is fed along by the rack C, and pinion D in the direction indicated by the arrow see Figs. l and 3, and the patterns L, L, as they rotate in connection with the spring I, give the gate or slide an up and down motion, and the strips N, will be cut in a waved manner thereby as shown in Fig. 1. When the ends of the strips have passed the cutters K, K, the projection (g) on the carriage back of the gate or slide F, will strike the inclined wedges or planes M, M, and the gate or slide F, will be forced upward beyond the reach of the patterns L, L. The finished strips are then removed and others secured to the carriage which is moved back to its original position by turning the shaft E, in the reverse direction and the stop (g) on the opposite end of the carriage will strike the inclined planes or wedges and throw them out from underneath the plate J, thereby allowing the spring I, to force the cutters K, K, down upon the strips and the ends of the plate J, upon the patterns or slide F, rotary patterns L, L, and the in- 10 L, L. The operation above described 1s clined planes or Wedges M, M, the above then repeated. parts being` arranged substantially as shown We do not claim the reciprocating` gate for the purpose specified. 5 or slide F, with cutters attached for they H.
