IMPROVEMENT IN TYPE-MACHINES.

Specification forming part of Letters Patent No. 169,701, dated November 9, 1875; applicationfiled June 3, 1875. I

To all rrhom itmay concern:

Be it known that I, ANsoN M. HOWARD, of

, Ilion, county of Herkimer and State of New 8 are details, showing inner face views of the parts of the type-wheel. 1

The object of my invention is to effect the reproduction, by machinery,.of single hardmetal type, or monogram-type. It consists, first, in the'combination ot' a bed-clamp, formed of three plates, for confining a gage-feeding rack, and single pieces of metal for writing and monogram type, and a clamp constructed to receive and confine single type or monogram-type while they are being used for making raised letters on blanks, and then permitting the original type to be removed, and the blanks with raised letters to be placed and confined in it, and used for producing facsimiles of the original hand-engraved type, and then permitting the type, which are reproductions of the original hand-engraved type, to be placed and confined in it, and used for making type and monograms for writing-machines and other machines, the aforesaid clampingwheel being placed on a shaft or arbor, which carries a toothed feeding-wheel, which gears with a toothed feeding-rack directly under it.

' It consists, second, in the combination of a toothed gage and feeding-wheel on the shaft and use my invention, I will proceed to describe it. 7 l

A is frame or bracket, shaped and constructed so as to form an attachment to any ordinary lathe or iron-planing machine. This frame or bracket, however, may be a part ofa complete machine designed especially for making type, it found most desirable. On the bed of this frame a clamp, B, is fitted to reciprocate. This clamp is formed of three plates, at b c, screwed together. Between two of the plates or and Z) springs m are placed, and on these sn'in 's a toothed a e and feedingrack, O, is arranged and suitably confined, and between the plates 11 and o blanksfor the type are confined, so as to move up and down freely,'suitable llfllfiSOOkEtS being formed in the plates forthe admission of these blanks between the plates. The feeding-gage rack'is made capable of yielding up and down, so that its teeth may be kept in gear with the wheel, working with it from the commencement to the completion of the operation, and when the last compression or swaging action takes place it may be seated .firmly on a solid bed. The adj ustability ot' the die-wheel, which will be presently described, requires this spring or yielding feeding-gage rack to beused, in order that when the impression upon the metal set in the bed is just begun, the feeding and gaging wheel and rack shall be perfectly in gear, and, as the impression is still further,

advanced, and the die-wheel requires to be lowered, the feeding-rack will yield and permit the die-wheel to be lowered, and, finally, when the impression is about completed, and the die-wheel has been lowered to the full extent required, the rack will rest upon a solid bed, the springs having been compressed so closely that their elasticity is overcome for the time being. It is important that the last operation of compression or swaging' shall be performed upon a solid foundation, in order to prevent'the type and dies from changing their relation to one another in the slightest degree. Directly above this clamp a clampingwheel, D, with a gaging and feeding toothed,

wheel, D, attached to it, is hung upon a shaft, 7

E, in a hanger, F, which is fitted to the bracket by means of dovetail connections d, and adof the-hub ofthe plate 0.

j usted up and down toward or from the clamp B by means of a hand-screw, G. This clamp is composed of three plates, 0 fg. The plate 0 is chambered, so as to form an annular shoulder at h, for shoulders 13 on the type to bear againstwhenthe type are clamped in position. This shoulder prevents the type falling out of the wheel when the machine is in operation. The plate fis grooved at j, in order to receive the flange which forms the shoulder of the plate e, and it is made to bear firmly against the, side of thetype, and thus clamp them against the plate 0 by means of the plate 9 and a nut, 70, which latter screws on the end The plate f will be cut away to a greater or less extent, so as to form a greater or less part of a circular disk, according to the number of die-type used in the clamp; and in the event that the whole of plate 0 is occupied with die-type, this plate will not be necessary, and spaces, with the clamping-plate g, only will be used.

The type which are used as die-type are made with working-faces which are segments of the exterior of a cylinder, and the blanks acted upon by them aro made to have working-surt'aces which are concave or segments of the interior of a cylinder;

The manner ot'clamping the type and blanks in the wheel D and clamp B is clearly shown in ,the drawings, and it will be understood that the motion of the rack or of the wheel thereby swage the letters upon the blanks.

The movement of the wheel, with letters of the or pattern type being broken off or worn out,

as would be the case if the die-type were not made single and clamped at a proper distance apart in the wheel.

What I claim is-- 1. The clamping-wheel for confining single type or monogram-type, in combination with the clamp formed of three plates for confining the gage-feeding rack, and single pieces of metal i'orwriting or monogram type, substantiall y as and for the purposes described.

2. The combination of a toothed gage and feeding-wheel, a type-clamping wheel, a toothed and vertically-yielding or spring gage and feed-rack, and the clamp for the blank typemetal, and spring and gage feeding rack, substantially as and for the purposes described.
