IMPROVEMENT IN mas FOR CUTTING our ORNAMENTAL FORMS OF PAPER.'

Specification forming part of Letters Patent No. 13?,063, dated March 25, 1873.

To all whom it may concern:

Be it known that I, ADOLPH DELKESGAMP, of Brooklyn, E. D., in Kings county, New York, have invented a certain Improvement in Dies for Outtin g out Ornamental Forms of Paper, of which the following is a specification:

The invention is intended more particularly for the production of variously-curved and elaborate slender forms in paper, to be ccmented upon glass globes and other objects of glass for exposure to the sand-blast. Paper is not cut by the sand, and protects the surface beneath it in its polished condition, while the surfaces not protected are rapidly abraded under the violent impact of the small gritty particles. The paper forms thus produced may obviously be useful for various other decorative and other purposes; and the present invention may be applied to the manufacture of forms in other material than paper.

I will proceed to describe what I consider the best means of carrying out the invention, as applied to the production of paper shapes for glass decorating. v

The accompanying drawing forms a part of this specification.

Figure 1 is a vertical section through the upper part of the bed and the lower part of the platen or plunger. Fig. 2 is a vertical section at right angles to Fig. 1. Fig. 3 is a top "iew of the bed with its attached male die; and Fig. 4 is a view from below, showing the under face of the plunger with its female die.

Similar letters of reference indicate corresponding parts in all the figures.

I can employ a press of any suitable construction, and operated by hydraulic force or by other means. I do not consider it necessary to represent the press, but only the novel of an inch, and thus initiates the formation of a female die, to be afterward completed, as set forth below. hardened steel or other suitable material, firm- 1y secured upon the upper face of a substantial bed-casting, b. The plunger a. is worked up and down through a considerable space say, an inch or more. The press should provide means for depressing it and its attachments with force, particularly at the lower extremity of its motion.

So far as thus described, the parts would cut out the forms successfully, but the thin and branching strips of paper thus cut out would be liable to stick either to the male or female die, or to both. 7

The nature of the work forbids the introduction of any ordinarymeans for clearing the parts. The male die must present a prac tically plane face to avoid distorting the delicate shapes thus produced. The.waste material cut out from the spaces in the pattern ten ding to remain around and within the spaces in the male die B, need not be so carefully treated; but I will describe the means which I have adopted, whereby the paper is freed from both, without distortion. I drill small holes thickly over the entire sunk portion of the female die A A producing the holes quite through the soft metal A, and also through the supporting-material a above it, and introduce corresponding slender pins in, screwed or otherwise secured in a plate, D, mounted above, and capable, not only of moving with the plunger, but also a quarter of an inch, more or less, motion up and down in a recess within the plunger. I correspondingly drill holes in the spaces around the male die B, and provide corresponding pins m correspondingly fixed in a slightly movable plate, M, below. The press operatesthe plate M and its attached pins on by cams and connections not represented, so that at each separation of the diesA and B, the pins m are protruded from their respective holes and actively push out the paper lying in their way. I

A gentle current of air from a fan or analogous apparatus may be brought to bear on the paper as soon as liberated by the pins, so as to more effectually remove the waste material; but in many cases such an addition may not be necessary.

The act-in g ends of the pins m should be B is the male die, formed of C. H. FANCHER. Farming and Gaging Butter Rolls.
