IVIACHINE FORCOLDr DRAWING noos, etc.
SPECIFICATION forming part of Letters Patent No.A 295,898, dared April 1, `1884.
Application filed September, 1983. (No model.)
To (L7/Z whom, it may concern,.-
Be it known that I, CHARLns C. BnLLINGs, of Boston, county of Suffolk and State of Massachusetts, have invented an Improvement in Machines for Cold-Drawing Rods, Shafting, 85e., of which the following description, in connection with the accompanying drawings, is a specication, like letters on the drawings representing like parts.
l This invention relates to that class of machines represented in United States Patent No. 130,465, and has for its object a novel construction of die and means for holding and adjusting the samenvherebythe rod or shaft may be drawn straight, and also to improvements in the clutch for holding the rod, as will be hereinafter described and pointed out in the claims.
Figure l is a longitudinal section of a suffivention to enable the same to be understood.
:v fr. Fig. 3 is a section of Fig. 2 on thadotted line x2; and Fig. 3 is a section of Fig".- l on the/ dotted line x3 x, to show the end ofthe head and jaws therein, forming the clutch. Fig.` 4 represents the knife-edge bearings removed; Figs. 5 and 6, modifications to be referred to.
A, on which is fitted a piston, B, having a rod, C, which at its outer end is providedwith a clutch, D, composed of a block of steel open at one side at a', to gain access to the clutch interior, and at one end a2, and chambered centrally for the reception of two toothed jaws aa,
shown as wedge-shaped at their backs, to bear against the correspondingly -wedge -shaped seats in the said chambered block.
Referring to Fig. 3, it will be seen that the head D at its front end is solid, except at its center, where it is mortised to receive the jaws a c, so that strain upon thelatter when drawing a rod cannot expand the head, as would be weresplit from its outer side to the jaw-receiving opening. The jaws, having been inserted into thehead,
then drawn or forced along the inclined seats of the head, toward its open end, until the toothed surfaces of the jawsbite the rod, and thereafter as the clutch is drawn in the direction of l4 f, which is pivoted by center screws,
'holder for the die.
the arrow on it in Fig. l the jaws close upon and hold the said rod sufficiently tight to draw g it through thedie e,to be described. The piston B isope'rated by water or other suitable fluid. The clutch-head in practice willbe provided with grooves to run on ways of the frame E, as does the cross-head of an engine. The die e, aloose block of steel perforated centrally and made cone-shaped externally, is tted into the conical interior ofthe die-seat f. This die seat (shown in Figs. l to 3) has an outer rim, f2, eX' tending through the seat-holder g, which latter is pivoted to the frame F by center screws, g,
located at right angles to the center screw, '2,
of the die-seat, so that the frame F and die-seat form a gimbal or universally-pivoted bed or The frame-work F has steel knifeedge bearings i, about oron which the seat-holder g rests and is rade movable. The die-seat f is provided with steel knifeedgebearings h,which rest against the flat side of the seat-holder g, constituting points on or about which the said seat f mturns with relation to the said holder. The anged or outer end of the die-seat is acted upon at preferably.
four p oints, ninety degrees apart, by adjusting screws m, which may be turned in or out each one more or less, and thereby turn the die-seat upon the holder about the points h, and the holder on the frame`F about the points v5, the
Vsaid adj usting-screws enabling the operator of the machineto tip the die-rest and place the die e in exactly the position desired to enable the rod R, being drawn through its tapered central opening, to be placed in exactly such position with relation to the movement ofthe piston and clutch, or to force the die to occupy and maintain a position directly in line with the center of the' clutch,which thus enables the rod to be drawn straight. These bearings or points la. i are exactly in line with the support* ing center screws, f2 before referred to.
As a modification I may support the dieseat on a holder, o, which is fixed with relation to the frame F; but in such modification I shall bevel the wall of the die-seat more than shown in Figs. l and 3, and support the said beveled portion directly upon bearings or surfaces, shown as rollers and marked n, the same adjustingscrews m being used to adjust and IOO position the dieseat and its die e with relation to the draft of the clutch, as described, I ernploying with the modied seat described a clutch-jaw, as shown and described-with relation to Figs. l to 3. In the patent referred to the die was self-centering, and there is no provision whatever to' adjust the same to the line of draft or to avoid drawing the rods or bars crooked.
The machine, with a die of proper shape, is adapted to cold-draw and compress solid or hollow rods or articles either round or square, or of other usual shapes.
I do not limit myinvention to the use of the exact clutch shown, as I may employ any usual clutch or device to grasp the rod; or it may be a tube. Y I do not claim a two-part adjustable die placed in a fixed seat and adjustable only in a radial direction with relation to the axis of the rod being` drawn, as such is described in United States Patent No. 168,975.
.I claim l. In a machine for cold-drawing rods, Snc., a clutch to hold the rod or article to be drawn, a die, arnovable or tipping,` die-seat to receive and hold the said die, and bearing-points to support the die-seat externally, and permit it with its inclosed die to be adjusted to tip or turn the die-seat and place the center of the die in proper relation to the line of draft ofthe clutch, combined with means, substantially as described, to act upon the die-seat at that side of it opposite the side acted upon by the said bearing-points,to thereby adjust the said dieseat,and with it its inclosed die, to operate a vand for the purposes set forth.
"the hollow head open at a and a?, the walls surrounding` the opening a', converging from within outward and affording beveled or 1n clined seats, and jaws having inclined backs L to fit in said seats, substantially as and for the purpose set forth.
In testimony whereof I have signed my naine to this specication in the presence of two subscribing'witnesses.
