JOEL R. BASSETT, OF CINCINNATI, OHIO, ASSIGNOR TO HIMSELF AND A. E. BATEMAN,
OF SAME PLACE.
MAKING BOLTS ANI) RIVETS.
Specicaton of Letters Patent No. 23,138, dated March 1, 1859.
To all whom it may concern:
Be it known that I, JOEL It. BAssnrT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Dies for Making Bolts and Rivets; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, made to form a part of this specification.
My invention relates to the construction and arrangement of dies for making bolts and rivets, described, specified and represented as follows:
By reference to the accompanying drawings Figure l, represents an external view of the die, with its parts in position to form the bolt or rivet. Fig. 2, represents detached sectional views of the same. Fig. 8, is a sectional view of the die showing the adjustable header within the same at its position when the head of the bolt or rivet is formed. Fig. 4, represents a steel shoulder piece which is adjustable and forms a part of the die. Fig. 5, represents a releasing rod formed to work through the die and release the formed bolt or rivet.
(A A) are die pieces made of chilled iron, of the form and configuration shown in Figs. l and 2. Longitudinally and partially across the faces of these die pieces are formed corresponding semi-circular cavities (a a) for the purpose of receiving and grasping, the rod to be worked, when the die pieces (A A) are brought in cont-act. At the out-er end of these cavities (a a) are formed the lips for compressing the rod and blank at the point of separation and facilitating the process of severing.
(g, g) are releasing rods formed with dovetailed shoulders (g) which are fitted into sockets in the die pieces (A A), as represented, in such manner that when the die (A A) is closed the shoulders (g) will form a part of the die, the cavities (f) across their faces corresponding with the cavities (a), and at the same be capable of being forcedforward, thereby releasing the formed bolt or rivet when the die pieces (A, A) are separated.
(fl, (Z) are adjustable steel abutments fitted into the die pieces in such manner as to form part of the same, while at the same time they may be easily removed for alteration or replacement. By means of these abutments any desired form may be imparted to the neck of the bolt or rivet without changing the die.
(la) is a heading recess formed in the die pieces (A, A) as shown in Fig. l, into which the header (H) is made to work, as shown in Fig. 3, thereby securing the for mation of the head of the bolt or rivet entirely within the die (A, A). The header (H) is adjusted to its socket (n) and secured to the header shaft (S) by means of a screw as represented. It will be readily seen that by means of packing the header may be easily adjustedto the thickness of the head of bolt or rivet required. The heading recess (t) may be made of any form required for the heads of bolts or rivets, the header being made of form to correspond.
The operation of making bolts and rivets by means ofthe within described die may be described as follows: Upon a suitable iron frame will be arranged a rotary stock; a portion of this stock being formed of a diameter somewhat greater than the other part is called a die stock and the remaining portion is called, in distinction, header stock. To the face of the periphery of the die stock at suitable intervals are hinged clamps. These clamps are made to fit and lie closely upon the face of the die stock. Dovetailed cavities are formed across the face of the die stock, and also across the corresponding face of the clamps. The die pieces are inserted into these cavities insuch manner that when the clamp lies closely upon the die stock the die pieces will be fitted exactly to each other, so as to form the die ready for the recept-ion of the rod, as thedie stock rotates. The rod to be worked' will be fed to the die, immediately after which the loose end of the clamp will be caught by a compressing roller attached to the frame and compressed so as to be held firmly against the die stock. The blank now being grasped tightly within the die, is severed from the rod by means of a cutter attached to the frame. The blank being severed from the rod` and the clamp still impinging against the compressing roller, thus securing the blank within theV die, and the stock still continuing to rotate, the die which contains the blank passes within the frame, and allows the point of the blank to be pressed against a plate upon the inner side of the frame; at this period of the rotation of the stock, when tne blank is most perfectly secured, the header which is arranged in the header-stock so as to correspond exactly With the headingl recess in the die, comes in Contact with a cam arranged within the frame, by means of which l,
it is forced into said heading recess against the inner end of the blank, thus forming the head of the boltI or rivet. rlhis being accomplished the stock still rotating, the header is withdrawn by means of a second cam and at the same time the clamp is made to retract, thus opening the die, and the outer ends of the releasing rods come in contact with cams which force them for- 15 H H.
