RO TARY SUPPORT FOR EIVlBOSSlNG-MACH INE PLATENS.

SPECIFICATION forming part of Letters Patent No. 757,759, dated April 19, 1904.

Application filed March 10,1903l To all whom, may concern Be it known that I, HENRY S. MAIDHOF, a

citizen of the United States, and a resident of vtion of the table.

theborough of Manhattan, in the city and State of New York, have invented a new and useful Rotary Support for Embossing-Machine Platens, of which the following is a specification. My invention consists of arotary support for the platens of .embossing-machines on which the impression member of the die is mounted. i

The object of my invention is to provide a suitable support which may be removably engaged with the top of the table of the embossing-machine, so as to be rotated thereon, upon which support the platen bearing the impres sion member of the die may be immovably mounted after it has been removed from its seat beneath the male member of the die.

By the use of this device the superfluous portions of the impression member of the die may be quickly and accurately cut away by the operator without requiring-the operator to change the position of the trimming-knife, the operator being permitted to rotate the platen together with its support, thus bringing all parts of the impression member of the die into a position to permit the operator to readily use the trimming-knife.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure l is a partial top plan view of the table of an embossing-machine, the platen being shown removed from its seat on the table and mounted upon the rotary support, the position of the support and the platen being also represented in dotted lines upon another por- Fig. 2 is an enlarged side elevation of the support, the platen, and a portion of the table. Fig. 3 is a vertical central section through the same, showing clearly the manner of securing the platen immovably to the rotary support and the manner of rotatably mounting the support upon the table. Fig. 4 is a top plan View of the support; and Fig. 5 is a top plan View of a portion of the table, showing the socket for receiving the pivot-pintle of the rotary support.

The embossing-machine table is denoted by Serial No. 147,098. .(No model.)

A, and the seat for the platen by a. A gageplate B is represented upon the top of the ta; ble, which gage-plate is provided with series of elongated slots 6, having enlarged openings 1; at their outer ends. The impression mom-.5 5 her of the die is denoted by C, and it is secured to the face of the platen D in the usual manner'as, for instance, by glue. This impression member 0 of the die is composed of any suitable material such, for instance, as cardboard.

The platen D is provided on its bottom face with the usual pair of projections 01, which are adapted to enter one ,pair of holes or recesses a in the seat a of the table for holding 5 the platen rigidly in position when used in connection with the male member of the die. (Not shown.)

The rotary support for the platen D is denoted by E, which support may be made of 7 wood. This support E is provided in its top surface with two series of holes or recesses a, arranged diametrically opposite each other, one pair of'which recesses is adapted to receive the pair of projections 03 on the under face of the platen D for mounting the platen immovably upon the said rotary support. This rotary support E is provided on its bottom surface with a downwardly extended pivot-pintle or projection c, which is fitted to enter a hole or recess in the table A for rotatably mounting the said support upon the surface of the table. 7

In the present instance I have shown the bottom of the rotary support as being pro 5 vided with a metallic wearing-plate 6 which is secured thereto by screws 6 which wearingplate has the pivot-pintle or projection 12' formed integral therewith. I preferably locate the hole or recess a in the top of the 9 table A for the reception of the pivot-pintle e of the rotary support near the front of the table Within convenient reach of the operator.

To prevent undue wear caused by rotating the support E, I provide a wearing-plate F at the top of the hole a which wearing-plate has a central opening f of sufiicient size to snugly receive "therethrough the pivot-pintle e of the rotary support- This wearing-plate is preferably countersunk, so that its top will be level with the top of the table, and it is secured in position by suitable fasteningscrews f.

If so desired, the operator may place the rotary support in other positions upon the table by inserting the pivot-pintle e into any one of the enlarged ends I) of the elongated slots Z) in the gage-plate B.

The operation of my invention is as follows: The impression-platen, with the blank thereon, which is to form the impression portion of the die, is first placed in position in its seat a and the male portion of the die, which is not shown herein, is depressed, forming an impression in the impression member of the die. The platen is then removed and placed upon the rotary support E. The support E is then rotatably mounted on the table. The operator then proceeds to cut away the superfluous portions of the impression member of the die. This may be done very rapidly and accurately, thus insuring a superior quality of work by bringing different portions of the impression member into position to be operated upon without causing the operator to change the position of the trimming-knife. The platen is also held Very steadily, which cannot be the case when the projections on the bottom of the platen are caused to rest upon the table while the operator is doingthe work, as has heretofore been customary.

The rotary support is shown as being provided with a plurality of pairs of holes or recesses e to enable it to be used in connectionwith platens of varying sizes, the projections on small platens being made closer together than on the larger ones.

It is evident that changes might be made in the construction and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but

What 1 claim is The combination with an embossing-machine table, of a platen-support rotatably mounted thereon, said support having a plurality of pairs of holes in its top surface arranged diametrically opposite each other, the holes of one pair being at adifferent distance from each other than the holes of another pair, the said holes being fitted to receive pairs of projections on platens.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 7th day of March, 1903.
