- ENGRAVlNG-MACHINE.
SPECIFICATION forming part of Letters Patent No. 238,882, dated March 15, 1881. Application fi ed April 12, 1880. (Model) To all whom 'it may concern Be it known that I, ALLAN E. FRANCIS, of Garrettsville, in the county of. Portage and State of Ohio, have invented new and useful Improvements in Engraving Machines, of which the following is a specification.
My improvements relate generally to engraving-machines employing a pantograph to which are connected the tracer and the graving-tool, and particularly to the means for facing the tool properly and the lever for operating the tool to the construction of the pantograph to the construction of the tracerarm and the means for adjusting the tracer; to the bed and supports of the machine, and the means for adjusting the pantograph and the work, all of which features will be particularly described with reference to the accompanying drawings, forming part of this specification. I In the drawings, Figure l is a plan view of the machine. Fig. 2 is a vertical section on line w m of Fig. 1. Fig. 3 is a side elevation of thetracer-arni and tracer; and Fig. 4 is a side elevation of the tool-carrying arm.
Similar letters of reference indicate corresponding parts.
A is the main bed of the machine, formed with a circular slideway that receives the ring-shaped bed a, from which rise the posts b b, thatcarry the supports for the work next described. The posts I) carry armsb, that are sustained on the posts by clampiug'collars, and upon the armsb are plates 0, pivoted at 0, so as to swing in horizontal planes. Upon the plates 0 are clamps d, held by screws 61, passing through slots in the clamps, so that the slots may slide lengthwise, and in flanges of plates 0 thereare fitted screws 6?, connected with the clamps d for moving them, as required. The arms I) are also fitted with setscrews 0 passing through curved slots in the arms and entering the plates 0 for clamping the said plates in any position to which they may be turned on their pivots. The ring-bed 01. turns freely on bed A, and is prevented from rising by pins or screws a, which are fixed at the inner side of the ring and take hold by their heads beneath bed A. In the side of bed A is a set-screw, ta for clamping the ring in position. This construction permits the work to be clamped between the clamps d in any required position within the areas of the ring-bed a.
From the bed A at one side rises the post B, which carries the tool, pantograph, and tracer, arranged as next described.v Upon the post B is a sleeve, 0, which is split lengthwise and connected by screws 0, by which the sleeve is clamped to the post. One portion of the sleeve 6 is formed with lugs in which is tapped a screw-rod, 0 the lower end of which bears upon the flange ofa collar,f, that is fitted on the post B, beneath sleeve 0, so that when the screws 0 are loosened the sleeve 6 and its at tached parts are supported on collar f, and may be raised and lowered by .turning the screw 6 The other portion of sleeve 6 is formed with armsf, in which is pivoted, by pinsf the yoke g, that carries the long arm g of the pantograph. The arm g is fitted to slide endwise in grooves of the yoke g, the setscrews-g serving to clamp it in position, and the outer end of arm g is forked to receive the pivoted yoke h, in which the tracer-arm his fitted. The arm h is formed with. grooves, (shown most clearly in Figs. 2 and 3,) which engage with tongues in the yoke it, so that the tracer-arm It may be moved endwise, the screws 7L tapped in yoke h serving to clamp the arm h. The outer end of arm h is formed with a flange or head having a V-shaped face, (see Figs.l and 3,) which flange carries a sliding piece, 6, that is held by a screw, i, passing into the arm lb through a slot in piece i, so that the latter is rendered vertically adj ustable. In suitable bearings in piece 2' the tracer la is fitted, so that it may slide freely up and down.
The tool or graver arm I is hung by a yoke, 1 in the long arm 9 of the pantograph, near the pivots f, in the same manner as the tracer arm. (See Figs. 2 and 4.) The rear ends of the tracer-arm h and tool-arm t are connected by a rod, l,which is pivoted by a knuckle-joint to each, and forms the short arm of the pantograph.
The tool stock or carrier m is fitted in bearings l of arm l, which bearings permit vertical movement, and the tool is raised by a spring, m, which is placed around the stock and bears between the arm I and a collar, m,
on the stock. (See Fig. 4.) The collar m is pivoted upon the tool-stock, and is formed with or attached to an arm, a, which has upon it a loose collar, n, that has a projection for entering the apertnred lug 1?, that projects from the sleeve 0, so that while the tool-stock is moved by the pantograph the arm it keeps the tool faced, or in the proper position for cutting.
Upon the'tool-arm Z is hung alever,0, which extends to a position for convenient use, and bears at its mid-length, by a pivoted piece, 0, upon the upper end of the tool-stock, so that by pressure of the operators hand on lever 0 the tool is forced down to the work.
The bed for carrying the pattern is supported by atubular post, 0, which is sustained on bed A by a screw-rodqfi, and nuts 1) F, as shown in Fig. 2, so as to be capable of adjustment radially as to the ring a. p is the bed, attached upon a supporting piece, 1", that is slotted to set over a lug, p, on the upper end of post (),so that thebed may bemovedlengthwise. The nut p serves to clamp the piece r in any position to which it may be moved, and the post 0, with the piece 1" and the bed 0, may turn on the rod p The bed p consists of a fixed portion and a loose piece, q, that is movable to and from the fixed portion. Upon the supports of the bed there are hung cam-levers q, fitted to bear on the outer edge of the piece q, for forcing the same toward the fixed bed. The patterns shown at 1' are formed with flanges that pro- 3 5 ject downward between the fixed and movable portion of bed 12, so that by operation of the cams q they may he clamped firmly. The tool 8 is clamped by its shank in the stock m. The shank is formed with a backward curve above the point, in shape the arc of a circle, so that the face of the tool projects forward, in which position it is retained by the arm a.
In operation the work to be engraved will be placed between the clamps d, and by ad- 5 justnient of the ring at, arms I), and plates 0 may be fixed in the desired position. The arms f will be adjusted vertically on the posts B, so that the too] shall be retained normally free from the surface of the work, and horizontally, as required. The sleeve 6 is then to be clamped firmly to the post B. The long arm of the pantograph is then to be adjusted given to the tool by the long arm g and short arm I of the pantograph, and the tool being at the same time pressed down by the lever o the pattern is reproduced upon the work, the depth of out being regulated by the pressure.
This construction furnishes a compact machine having a wide range of adjustment and affording great convenience for its operation.
Elaving'thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. In engraving-machines, the arm n, combined with the tool-stock m and the sleeve 6, substantially as shown and described, for the purpose of facing the tool.
2. In engraving-machines, the sleeve 0 and its tightening-screws e, the screw-rod c and flan ged collar f, combined together and with the fixed post B, substantially as and for the purposes specified.
3. In engraving-machines, the ring-bed a, carrying the work-clamps, combined with the fixed bed A, having a circular slideway and provided with a clamping-screw, a substantially as shown and described.
4. In en gravin g-niachines, the pivoted plates 0, sliding clamps d, and screw d combined with the swinging arms 1), posts I), and ringbed a, substantially as shown and described.
5. In engraving-machines, the tracer-arm h, formed with a V-shaped flange, the piece '5, correspondingly concaved, and the screw i, combined for operation substantially as and for the purposes specified.
6. In engraving-machines, in combination with the fixed bed A, the rod 19 and nuts 19 29, the tubular post 0, and slotted support Wot the pattern-bed 12, substantially as shown and described.
7. In combination with the bedp and its adjustable support 1", the sliding piece q and earns q, substantially as and for the purposes set forth.
