My invention comprises new andulsei'ul improv ments; in embossing presses, intended for stampin 01' forming raised characters in blanks or plates" of metal or other material.
More particularly my present invention 7 relates to changeable dies for said presses and in mea' ns for presenting the same coin Ven'iently to the hand of the operator so that the dies may be" quickly changed, thus shortening the intervals between impressions a-ntl' preventing the mounting of the wrong dies ifttheipres's".
In the accompanying drawings, Figure l is a front e'lerfation of an embossing press embodying improvements; Fig. 2 is an enlarged detail of the same in' section along thefline IIII in 1; Fig. 3 is a perspective of one of the changeable dies dismountof a modified form of the changeable die; Fig; 5 is an enlargedifront eleyation of the die magazine with the dies stored therein, and Fig: 6" a top plan View of the same.
The followingis a detailed description of the drawings reference being first had to Figs; 1,2a'1id 3; A is astam mg or efn boss- 111g press of conventional form provided with a'be'dB and a ram C. The bed andrain are shown provided, for the sake of illustration, with coacting inaleand fenl'alfe dies 1 andfZ at either end of the press, the'changea'hle dies, as' will be laterf des c'ribed, being shown interposed between the same.

Thus the eiid characters" are changed only at long inte'rvals, ifat'all, while the intervening'nnm- The dies 1 arid" 2. forrn' no'part of the present in dies which I will now proceed to describe. n a' line parallel with and adjacent to the front dge of the bed B, I provide said bed witha series ofupwardly extending studs {Bland in a parallel line adjacent to the rear edge of bed B a corresponding series of headed pins 4 upon which are mounted slidin'g collars 5 whos'e upper diameter is enlarge'd to" form shoulders 6. q Coiled springs 7 are mounted on said pins between the heads thereof andthe collars 5 to resiliently depress the latter. I t
The reino'yable dies are constructed as follows: 8 is the base plate having its forward end bent downwardly to form the handle 9 and I0 is a hole in pla'te 8 engaging one of the studs 3 when" the die is mounted in the press The'lower die'pla't e D, preferably the female die, is n'lou'iit'e'd' on the tipperface of the plate 8, as by rivets-l1, said die plate being preferably wider than said'b'ase' plate but the die portion of p'l'ate'D being within the lateral lifnits of said" base plate. The top plate I2 bears on asunder face the upper 01' male die plate'E. The said top plate is connected to the base plate8 by means of a' pairlof pivoted together brackets 13 and 13 which are respectively riveted or otherwise secured to said" base and top plates. The top plate" 12 is extendedrearwardly and provided" at its end with a' notch 14, which engages the collar ,5 under itsshoulder 6 on one of the pins 45. The changeable die isreadily mounted on the bed B by first engaging the notch 14 under the shoulder 6 or one o-f the spring pins & and snapping the hole 10 dewn over the corresponding stud 3. The die may he removed from the bed by lifting the-plate 8 until the stud 3 is disengaged from the hole 10 and drawingthe die fhrward until the notch 1-1 is disengaged froih't'he collar 5i The effect of the spring 7 ism hold the die open, as shown 111mg. 2 when the ram ,(lis raised so that the blanks inay be readily v inserted and removed. Fl hen the ra n is depressed, the spring 7 is coinp'res'sed and the die is. forced closed.v
Itlis evident vthat the dies maybe quickly chaiiged on the bed of the pressas required.
' protrude.
In embossing numbers on blanks the first die to the right in Fig. 1 is the unit die; the next to the left the tens die; the next to the left the hundreds die; and the fourth the thousands die. By increasing the number of positions for dies any number may be embossed. lVhere a series of numbers running say from one to nine thousand, nine hundred and ninety-nine, are to be impressed, the 1 die first is mounted on the units position and the desired number of impressions made; the 2 die is then substituted and so on until the number ten is reached when the 0 die is mounted on the units position and the 1 die on the tens position. In a similar manner the dies are changed and added to the hundreds and thousands positions until the highest number above named is reached.
In Fig. 4 I show a modified form. of changeable die wherein the lower and upper dies are mounted on the ends of a loop 12 of spring metal whose lower end is prolonged to form the handle 9 and provlded with a hole 10'" to accommodate the stud 3 of the bed B. The rear end of the loop may be notched as at 14" to engage the headed pin 4 to hold the die removably in place in the bed. In this case the die is normally held open by the resiliency of the loop 12 and the spring 7 is not required.
One of the chief merits of my changeable dies is the facility with which they may be interchanged to produce the required number on a series of blanks and it is therefore highly important that the dies be presented to the hand of the operator in such a manner that no sorting will be required but they may be picked up and inserted in the press without examination. For this purpose, I provide a magazine or case F, which is secured to the press in a convenient position, as shown in Fig. 1. Said magazine is in the form of a metal box having a solid back, sides and bottom, and divided by vertical partitions 15 in compartments a, b, 0, 03, etc., equal in number to the number of changeable die positions on the bed of the press. Thus compartment a is for the units dies; compartment 6 for the tens dies, &c'. The fronts of the compartments are partially closed by the wing partitions 16 leaving a central vertical slot of sufiicient width to permit the ends or handles 9 of the dies to The bottoms of said wing partitions are cut away as at 17 so that the bottom die in a compartment may be readily withdrawn forwardly permitting the superimposed dies to drop down in the compartment.
The dies are arranged in the compartment in numeral series from the bottom upward so that as a die is withdrawn at the bottom, the die of the next higher number takes its place and is next withdrawn, the dies as they are removed from the press being inserted in the top of the compartment, so that the necessary rotation is maintained. To facilitate the withdrawal of the dies from the compartments, the magazine is preferably inclined forward, as shown in Fig. 1.
vVhile my removable dies are primarily intended for the class of work above referred to, they may be used for any character of embossing with equal facility.
It is evident from the foregoing that by means of my invention the process of embossing is greatly simplified and facilitated and consequently cheapened.
What I desire to claim is 1. In combination with a press provided with a bed and a ram, a changeable die for said press comprising a lower die plate adapted to be removably mounted on said bed and an upper die plate connected to said lower die plate, but unattached to the ram and adapted to be forced down against the same by said ram, and means mounted on said bed and engaging said second die plate to raise the same when said ram is elevated.
2. In combination with a press provided with a ram and a bed, said bed being provided with a stud, a changeable die for said press comprising a lower die plate provided with a hole adapted to engage said stud and an upper die plate in hinged attachment to said lower die plate, said upper die plate being unattached to said ram, and adapted to be forced down on said lower die plate by the descending ram.
3. In combination with a press provided with a ram and a bed, said bed being provided with a stud, a changeable die for said press comprising a lower die plate pro-vided with a hole adapted to engage said stud andv an upper die plate in hinged attachment to said lower die plate and adapted to be forced down on said lower die plate by the descending ram, said upper'die plate being unattached to said ram, and resilient means for raising said upper die plate when said ram is elevated.
4. In combination with a press provided with a ram and a bed, said bed being pro vided with a stud, a changeable die for said press comprising a lower die plate provided with a hole adapted to engage said stud and an upper die plate in hinged attachment to said lower die plate and adapted to be forced down against the same by the descending ram, said upper die plate being unattached to said ram, and means mounted on said bed for ralsing said upper die plate when said ram is elevated.
