PANTOGRAPH.
JLPECEPICATION forming part of Letters Patent No. 350,027, dated September 28, 1886.
Application filed April 8. 1886. Serial No. 198,198, (No model.)
part of this specification.
This invention relates to certain new and useful improvements in pantographs; and the invention consists in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.
Figure 1 is a perspective of my improved pantograph. Fig. 2 is a section through one of the joints.
In the accompanying drawings, which form a part of this specification, A B 0 represent three rules pivotally secured together, as at (a, and in this construction these points are never changed in adjusting the device to produce drawings of different sizes.
D is an adjustable rule. or bar, which, to gether with the rules A and O, are provided with aseries of holes, consecutively numbered, by means of which and suitable thumb-screws or pins they may be pivotally secured together. As the rule or bar D has to be pivot-ally secured at two points, it necessarily fol lows that it should be numbered from both ends with numbers corresponding to those upon the rules A C. One end of the bars D and B are slotted,as shown, cut through a hole, I), at right angles to the slot, such holes being designed to receive the point and pen cil and to be held therein by the thumb-screws c, as shown.
E is a clamp designed to be secured to the edge of the drawing-table by the screw F. To
the upper end of this clamp is pivotally secured a block, G, to which theend of the rule A is pivotally secured by means of the pin or screw (1. The screws H, which pivotally secure the rules together, are provided with a cup-shaped washer, I, which forms a bearing for the head of the screws, and upon which they turn without unscrewing when in use.
In practice, fasten the machine securely at left side of table, about at the middle, bv means of the clamp E. If drawing is wanted larger than original, place pencil in arm B, and pointer in arm D; ifsmaller, reverse. If
'a drawing near the original in size is wanted,
let A D and A 0 cross each other at Fig. 1. If a very large or very small size is wanted, let A l) and A 0 cross at a higher figure, care being taken always to cross at same figure upon each rule, as 1 1 l 1, 9 9 9 9, 18 1818 18 18. Fasten pencil securely with thumb-screw one and onehalt' inch from point, and fasten pointer so that it touches paper very light when pencil is pressed down on paper. When drawing, take hold of pencil with right hand and let pointer follow lines in original.
What I claim as my invention is- In a pantograph, the combination of the rules A O, the rule B, pivoted on permanent pivots a to one end of said rules and provided with pencil-point, the rule D, adjustable on the rules A (J parallel with the rule B and carrying pointer, the block G,pivotally secured to the end of the rule A, and the clamp E, pivoted to the block G and provided with screw F, substantially as and for the purpose specified.
