STAMPING PATTERNS 0N ROLLERS.

' Specification of Letters Patent No.

To all whom t may concern:

Be it known that I, JAMES BAXENDALE,- of-the city and county of Providence and State of Rhode Island, have invented a new and useful Improvement in Machinery fo-r Engraving or Stamping Patterns on Rollers for Printing Text-ile Fabrics; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is a side view of a machine constructed according to my improvements; the front side ofthe frame being omitted, to show the operating parts more distinctly. Fig. 2, is a lan of the machine.

Similar letters of reference indicate corresponding parts, in both figures.

The nature of this inventio-n consists in stamping the rollers with any device, repeated in circular, spiral, longitudinal, or irregular succession, by means of a punch or punches att-ached to a weighted arm or lever, which is raised by a cam, and which falls on an elastic gage. The roller is placed in suitable bearings, in such a position in relation to the punch, thatit will receive the impression thereof, every time it descends; and it receives a rotary or longitudinal motion, or rotary and longitudinal motions combined, according to the required direction of the succession of the pattern. The elastic gage raises the punch from the surface of the roller, immediately after the blow is struck, and prevents it from being broken either by too severe concussion or by the movement of the roller while it remains in the'indentation it has made.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation.

.The working parts of the machine andV the roller are all supported in a framino', A, which consists of a bed-plate and side pieces. The driving shaft, B, of the machine rests in bearings at one end of the frame; and the roller, C, to havethe pattern stamped on it, in bearings at the opposite end; the roller being furnished with a spur wheel, D, by which it receives rotary motion through intermediate wheels, E, F,Y from a spur wheel, Gr, on the driving shaft.

The lever, I-I, which carries the punch, has its fulcrum on ,a pin, a, in a pillar, I,

secured to the bedl plate.` Its longer arm 10,332, dated December 2o, 1853.

is weighted by a weight, b, and in this weight, or in any suitable stock, is secured they punch, c. The extremity of the shorter arm of the lever comes below the fixed stud, d, which forms the axis of the cani, J, by

which theV punch is raised. The cam receives rotary motio-n through a spur wheel.l K, attached to it, from an intermittent wheel, L, driven by a spur wheel, M, on the driving shaft, and acts upon the short arm, and is of such form as to depress it gradually, to raise t-he punch, and then to let the punch fall suddently to strike a sharp blow. The elastic gage consists of a spring, N, of india-rubber, metal, or other elastic' ma# terial, supported by-a suitable standard, O, placed below the lever near the punch.

The machine is set in operation by giving rotary motion to the driving shaft, which causes the punch to rise and fall'frrapidly and strike the roller, while the latter moves upon its axis, thereby giving the roller a circular series of impressions at regular distances apart. In order to repeat the series of impressions, the roller would have to be moved longitudinally after every circular series is completed. The impressions may be made in a straight line across the roller, by giving it a longitudinal motion; and the lines may be repeated by giving the roller a slight circular motion after vevery one, and then reversing its longitudinal motion. The impressions may be made in spiral lines by giving the roller rotary and longitudinal mot-ions combined. I have only shown'the means of giving the circular motion to the vals of time, while the roller is moved iny the direction in'which the pattern is to be repeated, substantially as herein set forth.

JAMES BAXENDALE.
