MACHINE FOR TURNING TAPERED BOLTS.
SPECIFICATION forming part of Letters Patent No. 410,051, dated'August 27, 1889.
Application filed J une 29, 1389.
To a/ZZ whom it may concern,.-
Be it known that I, SAMUEL M. VAUOLAIN, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Turning Tapered Bolts, of which the following is a specification.
' The object of my invention is to construct a machine for turning tapered bolts. This ob ject I attain in the following manner, reference being had to the accompanying drawings, in which-- Figure l is a perspective view of sufficient of a machine to illustrate my invention. Fig. 2 is a plan view. Fig. 3 is a section on the line 1 2, Fig. 2. Fig. is a section on the line 3 4, and Fig. 5 is a section on the line 5 6,
Referring to the drawings, A is a tank or boX having projections a, in which are cut ways for the reception of tongues b b and c c of the cutting-dies B and C. The die B is the roughing-die, used to roughlyA cut the bolt t0 the required size for the die C. This die is the taper or finishing die, which turns the bolt to the taper required, so that it will accurately 'fit an orice reamed to the same taper.
Heretofore in turning taper bolts it has been the practice to turn them on alathe, and it has rested solely with the operator whether the bolt was accurately turned or not, and
consequently slight variations occur in the taper and an accurate iit is not insured.
D D are the spindles, at the lower end of which are chucks d d, which receive the heads of the bolt-blanks fr, as shown clearly in Fig. 3.
I will first describe the roughing-die B.
Adapted to ways on the base B of this die are slides E E, carrying the cutting-dies proper F F. The dies F are forked, forming prongs F, the edges fof which are the cutting-edges. On the under side of the blocks E are cam's e e, secured to a vertical' shaft e', attached to each block, and secured to each shaft is a lever e?, one of which has'an arm es. The two levers e2 62 are connected together by a link e4. The cams e. crest in grooves in the base B', so that on moving the levers e2 through the medium of the hand-lever e? the dies F' F can be moved toward'or from the bolts to be turned. In each block E is an adjusting- Serial No. 316,051. (No model.)
screw f for adjusting the cutting-dies F F in the blocks.
I will now describe the die for turning the f taper on the bolt.
In the shell of the die C is a central opening c for the passage of the bolt as shown clearly in Fig. 3, and radiating from this central opening are vertical slots for the reception, respectively, of the `cutters G G and guides H H. In one side of each cutter is a groove g, in which rests the hooked end 't' of or where a regular taper is necessary the cutters can be cut in the first instance to the taper, and then as they become worn can be taken up by the mechanism described. Each cutter G has a cutting edge lo its entire length, and at the top a cuttingedge k, which faces the under side of the head of the bolt w.
This under side of the head is first roughfaced by the roughing-die B. The guides H H for the tapered bolt can be adjusted to accord with the taper of the bolt bythe three set` screws It h h. The set-screw h passes into the die, while the set-screws h press against the die. The spindles D, to which are secured the chucks d d, can be guided in any suitable frame-work, the spindle not only having a limited vertical movement, but also a rotary movement.
The mechanism for operating the spindle can be the same as used in drilling-machin es, the bolt carried by the spindle being forced into the die, and as it rotates the necessary taper is turned upon the bolt.
The tank A can be partially filled with oil,
so that the cutters are at al1 times lubricated.
I claim as my inventionl p 1. The combinano "of the tank A with dies Band C, one a roughing-die and the other a tapercutting die, said dies being mounted in said tank with spindles carrying the bolts to IOC Vguides and the cutters, substantially as described.
4. The combination of the taper-cutting die, the shell, vertical cutters therein, said cutters having a groove g, with a bolt I, having a hooked end adapted to said groove, and adjusting-screws J J, substantially as and for I[he purpose set forth.
5. The combination of the base B, slides E E mounted thereon and carryingdies FF, forked, substantially as shown, with levers, and cams connected to said levers, whereby on the movement of one of said levers the dies F F will be adjusted from or toward each other, substantially as described.
6. The combination, in a die for turning tapered bolts, of the shell, the cutters G, mounted therein,`having a cutting-face 7o for the shank of the bolt, and a cutting-face k for the under side of the head of the bolt, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
SAMUEL M. VAUCLAIN.
