Specification of Letters Patent.
Patented Dec. e, 1910.
Application filed January 6, 1910. Serial No. 536,672.
To all whom it may concern:
Be it known that 1, WILLIAM B. Fos'rER, residing at Norwood, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Pantographic Pyrographs, of which the following is a specification.
It is the object of my invention to produce a pantographic pyrograph, and to provide certain novel and useful improvements in a device of this character, and the invention will be readily understood from the following description and claims, and from the drawings, in which latter Figure 1 is a perspective view of my improved device, showing the same adjusted for reproducing matter on a substantially thick article from a thin pattern, the surface plane of the reproduction being at a substantially higher elevation than the surface plane of the pattern. Fig. 2 is a perspective view of the securing means for the pyrographic hand-instrument, showing the parts in partly assembled relation. Fig. 3 is a cross-section of the same in assembled relation, taken on the axial line of the pyrographic handle and showing the tube therein partly in side elevation. Fig. 4 is an axial section showing the joint between the bars of the pantograph frame having the tracer-rod therein; and, Fig. 5 is a plan view of the securing means for the pyrographic hand-instrument, the pivoted clasp of the same being swung into open relation.
A A and B B represent the pantographic bars having joints C between the same. These joints comprise thimbles 0 provided with threaded shanks c which are received through apertures a and b in said bars, the threaded ends of said shanks receiving nuts 0 for holding the bars about the shanks. Each of the respective bars is provided with a suitable number of said apertures a and b, so that the joints may be located at different points lengthwise of the bars for making reproductions of the same size as the pattern, or larger or smaller than the pattern, as may be desired. One of the thimbles and nuts is also located at the free end of each of the bars A and B.
D D are supporting rods, D is a tracerrod, and D is a oositioning-rod. The supporting rods D l) are located at the free end of the bar B and at the rear joint between the bars A and B. The tracer-rod is located at the forward joint between the bars B and A, and the positioning-rod is located at the free end of the bar A. The rods pass through the bores of the thimbles at their respective locations. They have the thimbles secured thereto at desirable elevations by means of thumb-screws c for adjusting the bars of the pantographic frame to desired elevation to accommodate articles of various thicknesses upon which the Work is to be performed. The positioningrod has a positioning-block e at its bottom which is provided with prongs 6 arranged to be forced into the table upon which the device is to be used.
F is a pyrographic hand-instrument and comprises a handle G through the bore 9 of which a tube H passes, the tube being held at desirable elevations with relation to the handle by means of a thumb-screw g. A flexible hose I is arranged to be received over the upper end of the tube, where a spring-support K is received about the upper end of the tube and the part of the hose adjacent thereto, for preventing kinking of the hose at the tube, and resiliently supporting the end of the flexible hose adjacent to the tube. The free end of the tube may be provided with a similar springsupport K arranged to be secured to a suitable pipe from which the fuel-supply is received.
The tube is provided with a passage h extending longitudinally thereof and at its lower end has a burner-point h, the passage terminating adjacent to the burner-point, where lateral apertures 72, pass through the wall of the tube and communicate with the passage. The supply of fuel passes through the hose and tube in the form of vapor which ignites at the outer ends of the apertures h for maintaining the burncrpoint 71. in heated condition. This pyrographic instrument is detachable from the pantographic frame and is arranged for employment as a hand-instrument. The handle G of the same is provided with an annular recess 9 L is a bracket which ex tends upwardly from the bar B and is provided with a fork M at its upper end the tines m of which are of spring material and have inwardly curved fingers m at their outer ends. The distance between the inner faces of these curved fingers is less than the O is aclasp and comprises an arm 0 pivoted at 0 to the bar B, and having an elongated slot 0 extending from one of its sides and registering with the elongated slot N, the side walls of the elongated siot 0 extending transversely to the side walls of the elongated slot N. The elongated slot' N permits the tube H to be passed slantingly through the bar B and permits'the upper end of the handle G to be forced in a direction longitudinal of the bar B for forcing the recessed part of the said-handle between the tines of the fork M. When so positioned, the clasp O is swung on its pivotfor bringing the side walls of the elongated slot 0 into engagement withthe front and rear faces of the tube H, the side faces of said tube being engaged by the side walls'of the elongated slot N, thereby centering the tube. The side walls of the elongated slot 0 prevent movement of the tube longitudinally of the bar B and the side walls of the elon-' gated slot N prevent movement of the tube laterally of the bar B. The clasp O is provided with lips 0 0 received against the respective side edges of the bar B for maintaining the clasp in clasping position, and is also provided with a finger-piece 0 for readily releasing and closing the same.
The bar B has a forward depending extension 13 upon which a guiding handle P, preferably of heat-insulating material, is located. By means ofthis guiding handle the tracer-point d at the end of the tracerrod D is caused to follow the lines of the pattern, represented at Q, and theburnerpoint h is directed across the surface of the article upon which the pattern is being reproduced, represented as a box R, and held at proper elevation with relation to said surface for properly reproducing the same ac cording to the character of work being done.
The pantographic'rods D, D, D are of substantial length and the pantographic bars are adjustable to considerable variations of elevation lengthwise of the rods for permitting the pantographic bars to be raised to substantial height above the lower ends of the rods for permitting reproductions to be made upon articles varying considerably in height, from patterns of substantially similar thicknesses. Thusin the drawing I have indicated the reproduction being made on a box of substantial height from a pattern of minimum thickness, for instance, a pattern on a sheet of paper.
Having thus fully described my invention, what I claim as new and desire to pyrographic" hand-instrument comprising a handle and a burner-tube, one of sald bars being provided with an elongated opening extending lengthwise of said bar, a clamp on said last-named bar extendingabove the same and received about said handle and a keeper pivoted to said last-named bar and providedwith a slot the side-walls of which extend crosswise of the side walls of said elongated opening for positioning said tube lengthwise of said elongated opening, substantially as described.
