UNITED STATES PATENT OEETCE.
MOORE HARDAWAY, OF ST. LOUIS, MI SOURI.
IMPROVEMENT IN MACHINES FOR MAKING BOLTS.
Specification forming part of Letters Patent No. 44,623, dated October 1l, 1864.
To all whom it may concern.-
Be it known that I, MOORE HARDAWAY, of the city and county of St. Louis, and State of Missouri, have invented a new and useful Improvement in Machines for Making Bolts and Rivets; and I do hereby declare that the following is a full and clear description thereof,
reference being had to the accompanying drawings, and to the letters of reference marked thereon and made to form a part of this specification.
Itis well known that the bolts and rivets made by means of horizontal or reciprocating bolt and rivet machines now in use are in many instances veryudefective, and, in some cases, entirely unfit for use, owiu g to the strain given to the said bolts or rivets in releasing them from the dies.
rlhe object of this invention is to overcome the aforesaid difficulty and at the same time to produce a very simple, cheap, durable, and effective machine for making bolts and rivets; and the subjectmatter of my invention relates to the mode of operating the diebox, die, and plunger or header, by means of which the formed bolt may be released from the die Without strain or injury of any kind, as hereinafter set forth and represented.
In reference to the accompanying drawings, Figure 1 is a top view or plan of my improved machine. Fig. 2 is also a top view ofthe inarhine with a portion of the die-box and die removed in order to show more clearly the operation of the Working parts of the machine; and Fig. 3 is a vertical sectional view of the improvement, taken through the red line a: x, Fig. 1.
A represents a platform or bed upon which the machinery is arranged to operate.
b represents the diebox, which will be constructed in a strong, substantial manner, and adjusted upon the bed A, so as to be movable longitudinally. This box b is made with a recess in its front end which is adapted to receive a die, as c, and the said die may be rinly and properly secured by means of screws (not shown) working through the box b.
d d are clamps, one of which, d, may be in a fixed position, while the other, d', is movable, and constructed and arranged to operate by means of suitable devices, as, for instance, the cam e of shaft E, bar e', projection e, and proper springs, (not sbown,) in such manner that the said clamps d d may be adapted, at certain proper periods in the operation of the machine, to grasp the blank bolt and secure the same rigidly during the process of heading, after which the movable clamp d will bc retracted so as to release the formed bolt and allow the same to fall from the machine. The said clamps may be provided with cutters, as g g, by means of which the blank bolts may be severed from long rods suitable for the object desired.
The normal position of the said box b will be that in which the face of its contained die will bear against the said clamps, and it will be secured in or returned to this position, as the case maybe, by means ofa suitable spring. The said box b, with its contained die, may be withdrawn or retracted from its said normal position atcertain suitable periods, hereinafter described, by means of a bent lever, f', which is pivoted to the bed A at j". The said lever is attached to the box b and may be actuated by means of a cam, h, upon shaft E, in such manner as to operate the said box b, so as to release the formed bolt from the die at proper periods.
K represents the plunger or header, which will be adapted in form and size to iit and Work Within the die that may be employed, and it will be operated, with reference to its forward motion, by means of which the head of the bolt may be formed, by a suitable cam, as p, upon shaft E, and it may be retracted when released from said cani by means of a suitable spring, as it. (Seenin Fig. 3.) All the working parts of the aforesaid machine may be formed of suitable metal.
Having thus described the construction of my invention, l will proceed to explain the operation of the same.
llhe position of the Working parts of the inachine being the saine as shown in Fig. l, and the shaft E being made to rotate the rod from which the bolts or rivets are to be made, being rst properly heated, may be fed to themachiiie. The end upon which the head is to be formed being inserted within the die c, the cani e will be made to operate the clamp d through the medium of bar e in such manner that the blank bolt may be grasped firmly by the said clamps d d. At this period in the operation of the machine the cam p is made to force the header 7c forward into the die c against the blank bolt, thereby upsetting` the saine in such manner as to form the head of the bolt to correspond with the internal coniguration of the die. At this period in the operation, when the head of the bolt is completely formed, the cam l1, is made to actuate the bent lever fin such manner as to retract the diebox b with its containeddie, and, the movable clamp-die d being` also retracted by means of a spring or other suitable device, the formed bolt is, without strain or injury, and in a perfect condition, releasvd from the machine, the header 7s remaining stationary until the bolt is entirely free from both dies, y
Fig. 1 represents the working parts of the machine at that period in the operation at which the blank bolt may be fed to the die, Fig. 2, that at which the bolt is fully formed, and Fig. 3 that at which the formed bolt is discharged from the die and allowed to fall from the machine.
Headers and dies of different sizes and forms will bc employed in accordance with the nature of the result desired.
I do not claim or confine myselfl to the precise construction and arrangement of the devices by means of which the within-described operation of the said die-box and header and movable clamp-die may be accomplished as I am fully aware thatthe saine result may be effected in various ways without departing` from the spirit ot' my invention 5 but,
Having thus described the construction and operation of myinvention sufficiently to enable persons skilled in the art to which it appertains to make and use the same, what I claim as new, and desire to secure by Letters Patent,
The combination. of the die-box b, header 7c, and clamp-dies d d, in a bolt or rivet-heading` machine, when operating` in the manner and for the purpose herein set forth.
In testimony of which invention I have M. HARDAWAY.
