WILLIAM H. HOPE, ,OF PROVIDENCE, RHODE ISLAND.
PANTOGRAPH ENGRAVINGr-MACHINE.
To all whom it may concern Be it known that I, "WILLIAM H. Horn, a citizen of the United States, and resident of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Pantograph Engraving-Machines, of which the following is a specification.
My invention relates to a pantograph engraving machine adapted for engraving the surface of calico printing rolls; and it consists in the improved construction of the machine, whereby great simplicity and efliciency is secured.
In the accompanying drawings: Figure 1 represents a front elevation of the machine. F ig. 2 represents a rear elevation. Fig. 3 represents the right hand end elevation. Fig. 4 represents a transverse section.
In the drawing, A represents the frame of the machine, B the pantographic carriage for imparting translatory movement to the diamond operating carriage C; and D the pantographic carriage for imparting rotary movement to the printing roll E. The pantographic carriage D is provided with the guide rollers F, F, for forward and backward movement upon the tracks G, G, the said carriage D being provided at its right hand end with the uprights H, H, which serve to support the adjustable rack I the teeth of which, are held up to engagement with the teeth of the gear J, by means of the spiral spring K, thus preventing back-lash between the rack and the teeth of the gear. The gear J is located at the end of a shaft M, upon which is attached a roller L, which serves to support one end of the printing roll E for revolution, the opposite end of the said roll being supported by the idler roller L.
The carriage B to which the stylus N, is attached is located intermediate of the diamond-operating carriage C, and the rolloperating carriage D, the said carriage B being provided with the rollers O, O, which travel on the tracks P, P, of the carriage I). The carriage C is operatively connected with the carriage B by means of the bracket Q secured to the said carriage at the point 5, and provided at its outer end with the Specification of Letters Patent.
Application filed February 3, 1913.
Patented Nov. 1'7, 1914. Serial No. 745,841.
loosely held pin R, which enters the groove 0, of the carriage B and is held in engagement therewith by means of the spring d. The carriage C is supported for movement on the rollers e, e, and is provided with the uprights S, S, which support the adjustable rack T, that engages with the teeth of the gear U, for the transmission of movement through the shaft V, to the gear WV, and thence to the rack X which is connected with the carriage Y upon which are placed the diamond holders Z.
By changing the sizes of the gears J and U with corresponding adjustment of the racks that engage therewith, the dimensions of the engraving may be either increased or diminished as desired.
I claim:
1. In a machine of the character described, the carriage for the stylus, the pantographic carriage the movement of which operates to impart rotary movement to the roll which is to be engraved, and the intermediate rack and gear by means of which the said movement is transmitted.
2. In a machine of the character described, the carriage for the stylus, the carriage for the diamond holder and the pantographic carriage which operates to impart translatory movement to the carriage for the diamond holders, and the intermediate rack and gear by means of which the said movement is transmitted.
3. In a machine of the character described, the carriage for the stylus, the pantographic carriage the movement of which operates to impart rotary movement to the roll which is to be engraved, and the intermediate rack and gear by means of which the said movement is transmitted, with the carriage for the diamond holders, the pantographic carriage which operates to impart translatory movement to the carriage for the diamond holders, and the intermediate rack and gear by means of which the said movement is transmitted.
SOCRATES SGHOLFIELD, BENJAMIN L. DENNgS.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. 0."
