Unirse STATES PATENT OFFICE.
ZACHRY T. FURBISH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE NORTH BROTHERS MANUFACTURING COMPANY, OF SAME PLCE. l
APPARATUS FOR MAKING RIBBED SLEEVES OR WHEELS.
SPECIFICATION forming part of Letters Patent o. 659,522, dated October 9, 1900.
Application filed August Z7, 1898.
To all whom, it may concern:
Beit known that I, ZACHRY T. FURBISH, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Apparatus for Making Ribbed Sleeves or Wheels, of which the following is a specification.
The object of my invention is to rapidly and accurately manufacture articles of tubular form having intern al ribs or splines formed thereon, as fully described hereinafter.
In the accompanying drawings, Figure l is a sectional View showing the first step of my improved method of making sleeves with internal ribs. Fig. 2 is a section on the line 2 2, Fig. l. Fig. 3 is a View of the spiral mandrel. Figs. 4, 5, and 6 are views showing different steps of the method. Fig. '7 is a section on the line 7 7, Fig. 6. Fig. 8 is a sectional view of the blank. Fig. 9 is a sectional View showing the blank pressed to form the internal ribs, and Figs. 10 and ll are views of a finished ratchet-wheel for a spiral ratchet drill or screw-driver.
In the manufacture of ratchet-wheels for spiral ratchet screw-drivers or drills it is essential that the spiral splines or internal ribs of the ratchet-Wheel which travel in the spiral grooves of the stem shall be made accurately and of sufficient strength to Withstand the pressure exerted upon the tool. To form these ribs by casting is not satisfactory. By my improved method I can form the ribs cheaply and rapidly. At the same time they will accurately t the spiral stem and owing to the fact that the metal forming the ribs is pressed from the tube and condensed the metal is toughened and is much finer and the spline or rib is much stronger than when the spline is cast in the wheel.
Referring to the drawings, A is a die adapted to fit a power-press.
B is a mandrel having two spiral grooves therein in the present instance.
D D/ are two plungers adapted to snugly fit in the opening of the die, and each plunger is recessed to fit over the mandrel. The plungers D D' are mounted on suitable heads operated by the mechanism of the power-press.
(Not shown.) Any suitable press may be used.
serial No. 689,694. (No modem a is the'blank-in the present instance a short section of brass tubing, Fig. 8. This blank is driven into the die A, and the mandrel is preferablydriven into the blank so as to insure a snug fit.
In making heavy splines or ribs on comparatively-long tubes the two plungers D D are first moved into contact with the ends of the blank', Fig. 4. The plunger D is then forced forward, While the plunger D remains stationary, Fig. 5, thus forcing the majority of the metal of the blank into the spiral groove of the mandrel. The other plunger D is then forced against the blank, While the plunger D remains stationary, Fig. 6, completing the formation of the ribs and making a rib that will accurately iit the grooves in the mandrel, as shown in Fig. 9. The finished blank is shown in Fig. 9, and this blank can be turned down and ratchet-teeth cut therein, if necessary, 'as shown in Figs. 10 and Il.
It will be understood that other than spiral ribs may be formed on the interior of the tube; but I have shown the spiral form, as it is especially adapted for use in the manufacture of splined nuts for ratchet-tools.
I claim as my inventionl. The combination of a die, a grooved mandrel, the mandrel anddie being so proportioned that the tube to be acted upon can be inserted between the two, with plungers adapted to act on each end of the tube and compress the same, the metal displaced by the compression entering the groove in the mandrel, substantially as described.
2. The combination in a die adapted to receive a tubular blank, a mandrel having a groove therein adapted to be mounted in the blank, two plungers adapted to act on the ends of the blank and compress it longitudinally, with means Afor first moving one plunger to displace a portion of the tube and then moving the other plunger to complete the displacement, substantially as described.
3. The combination of a die adapted to receive a tubular blank, a mandrel having a spiral groove therein adapted to the tubular blank within the die, two annular plungers adapted to press against the ends of the tu- IOO billar blank, with means for moving one plunger while the other is stationary so as to partially form a spiral rib on the interior of the blank and then moving the other plunger While the first-mentioned plunger is stationary so as to complete the formation 0f the rib, substantially s described.
In testimony whereof I have signed my naine ro this specification in the presence of two subscribing witnesses.
