JOEL DICKINSON, OF NEWARK, NEVJ JERSEY.
DIE FOR FORGING PROJEGTILES AND THE LIKE.
Application filed January 13, 1919.
To allwhom it may concern:
Be it known that 1, Joan DIoKINsoN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New J ersey, have invented new and useful. Improvements in Dies for Forging Projectiles and the like, of which the following is a specification.
i The objects of this invention are to provide improved dies for pressin hammering or forging both the cylindrical portion and the tapered end of a projectile at the same time; to provide such dies which can also be utilized for cutting oil the large end of the projectile after the same has been hammered or forged into shape; to secure the effect of a fiat upper die in hammering the cylindrical portion of 'the projectile and yet enable the conical end to be shaped at the same time; to secure an improved product without the loss of time or labor, and to obtain other advantages and results as may be brought out in the following description.
Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views,
Figure 1 is a perspective view of the lower die of a pair embodying my invention;
Fig. 2 is a perspective view of the upper die of a pair embodying my invention;
Fig. 3 is a side elevation of a pair of my improved dies slightly separated, and
Fig. 4 is an end View of the same.
In said drawing, 1 indicates the upper die and 2 the lower die of a pair of forging dies of my improved construction, it being understood that the lower die 2 is adapted to be supported upon any suitable kind of a bed and the upper die held by its upper part 3 in any suitable means, such as a hammer or press, by which it can be reciprocated up and down with respect to the lower die. I have not shown the bed or hammer, as these parts are old and wellknown in the art and in no way affect the relation of the dies to said parts as it has previously existed.
The face of the lower die has a longitudinal groove or recess 4 to receive the pr ojectile, said groove or recess having a mam substantially semi-cylindric port1on which opens out through one end of the die 2, to receive the body of the projectile, the other end of the groove or recess being conically tapered, as at 5, to shape the tapered end Specification of Letters Patent.
Patented July 8, 1919. Serial No. 270,896.
of the projectile and opening at its point or apex through the other end of the die 2.
Through the side wall of this groove or recess 4 is a gap or notch 6 to receive a turning tool as is common and well-known to those skilled in the art.
The face of the upper die 1 is stepped, as at 7, 8, the loWer portion 8 being at that end of the die which forms the tapered end of the projectile and being recessed, as at 9, to correspond to the lower die and fit said tapered end of the projectile. The other portion 7 of the upper die is substantially plane or flat and adapted to simply hammer the cylindrical portion of the projectile as it lies in the groove or recess of the lower die.
It has been found that by the use of my improved forging dies as described, a pro jectile can be very effectively and accurately shaped, both as to its cylindrical body por- Lion and as to its conical or tapered end, and furthermore after such shaping, it is possible with my improved dies to cut off or square the large end of the projectile ready for further operations upon the same. Heretofore it has been the practice to saw off this large end of the projectile, while still hot, and such an operation has been both expensive and dangerous, but with my improved upper die the end of the projectile can be cut off by using a suitable cutter of the common knife type and employing the upper die as a hammer. Preferably the projectile, when ready for cutting, is reversed in its groove or recess, so as to bring the point of cutting central under the upper die, although still beneath its substantially plane or flat portion 8. lVorkmen then hold the cutter transversely of the projectile at the point where it is to be cut off and strike it a blow with the upper die as a hammer; by turning the projectile and striking the cutter in its successive positions the projectile is quickly and squarely cut of? at the desired point, and furthermore it is done With little labor and loss of time and with no danger as it is a method of cutting off smaller rods and bars which is familiar to the workmen.
While I have shown my invention adapted for the forging of projectiles, it will be understood that it might be employed for other forgings having a body portion and a differently shaped end and which require to be cut off at one end after forging; therefore I do not Wish to be understood as restricting myself except as required by the following claims when construed in the light of the prior art.
Having thus described the invention, what I claim is.
1. Forging dies of the character described, having in their cooperating faces one a groove or recess with a body portion and a differently shaped end portion and the other a substantially plane portion opposite said body portion of the groove and a projecting end portion opposite the end portion of the groove and correspondingly grooved Or recessed, whereby the upper die may also be used as a hammer in cutting off the end of the forging.
2. Forging dies of the character described, having in their cooperating faces one a groove or recess with a' body portion opening through one end of the die and a differently shaped end portion and the other a substantially plane portion opposite said body portion of the groove and a projecting end portion opposite the end portion of the groove and correspondingly grooved or recessed, whereby the upper die may also be used as a hammer in cutting 011' the end' of the forging.
3. Forging dies of the character described, having in their cooperating faces one a groove or recess wlth a body portion open- Gopies of this patent may be obtained for mg through one end of the die and a differently shaped end portion and the other a substantially plane portion opposite said body portion of the groove extending from one end of the die past the middle of its face and a projecting end portion opposite the end portion of the groove and correspondingly grooved or recessed, whereby the upper die may also be used as a hammer in cutting off the end of the forging.
4. Forging dies of the character described, having in their cooperating faces one a groove or recess with a semi-cylindric body portion and a difierently shaped end portion and the other a substantially plane portion opposite said body portion of the groove and a projecting end portion opposite the end portion of the groove and correspondingly grooved or recessed, whereby the upper die may also be used as a hammer in cutting 0d the end of the forging.
5. Forging dies of the character described, having in their cooperating faces one a groove or recess with a semi-cylindric body portion and a tapered end portion and the other a substantially plane portion opposite said semi-cylindric body portion and a projecting end portion opposite the tapered portion and similarly grooved or recessed, whereby the upper die may also be used as a hammer in cutting 05 the end of the forgmg.
