APPARATUS FOR CUTTING UMBRELLA-NOTCHES.

SPECIFICATION forming part of Letters Patent No. 439,437, dated October 28, 1890.

Application filed August 14, 1890. Serial No. 362,009. (No model.)

To all whom it may concern:

Be it known that I, ORREN M. SMITH, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Cutting Umbrella-Notches; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in apparatus for cutting notches in the flanges of that part of umbrella furniture technically known to the trade as umbrella-notches.

The object of the invention is to provide a simple, rapid, and effective means for forming notches in umbrella-furniture; and the means consist in the combination of a frame carrying a series of saws or cutting tools, said outting-tools being arranged to move upon a guide and over a socketed punch on which the article to be notched is placed.

The invention also consists of a cutting or notchin g tool made up of a series of saw-blades held by suitable means to converge inwardly; and the invention further consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claims.

For the purpose of illustrating my invention I have shown but a single cutting or notching implement with the accessories thereof,though in practice a gang of the same are used and are attached to suitable operating mechanism, supports, (he.

In the accompanying drawings, Figure 1 is a perspective view of the cutting implement, the guide being shown partly extended and the socketed plunger lowered with an incomplete notch in position thereon. Fig. 2 is a sectional view. Fig. 3 is a transverse sectional view through the line a: a; of Fi 1. Fig. 4 is a section through the socket and completed notch.

A and A refer to the upper and lower rings, which are constructed to receive the upper and lower ends of the saws or cutting-blades B, the ends of which are stepped or shouldered to lie in recesses formed in said rings. These saw blades taper longitudinally at their cutting-edges and are set in the rings A and A to converge inwardly or toward the center of said rings. The saws B are disposed equally, with the exception of the saw I), which is interposed to cut the notch in which lies the twisted or connected ends of the wire which passes through the ends of the ribs of the umbrella. The gang of saws and the upper and lower rings, as hereinbefore described, may be wholly or partly covered bya suitable casing, and the operating mechanism for reciprocating the saws can be suitably c011- nected or attached to one or both of said rings; or said saws may be held stationary While the guide therefor and socketed plunger reciprocate.

C refers to a guide, which fits snugly within the upper ring and is provided with longitudinal grooves 0, into which the cutting-edges of the saws pass, and this guide may be provided with a suitable collar or its equivalent forlimitingthe movement thereof downwardly and within the saws.

D refers to what I term a socketed plunger, the same being provided at its upper end with a socket d, within which will lie the umbrella-notch E, while the flange thereof rests upon the end surface of the said plunger. The incompleted umbrella-notches are fed into this socket, which moves upwardly within the ring A, so that the saws will contact with the flange e of the umbrella-notch, and the movement of the socketed plunger D or the gang of saws will out the notches. The depth of the notches can be regulated by the movement of the saws or socketed plunger. After the notch has been cut the guide 0 descends and forces the notch out beneath the lower ring A.

It will be readily seen that by means of the hereinbefore-described implement the umbrella-notches can be completed rapidly and with precision.

It is obvious that the socketed plunger D is recessed, as shown at d, to correspond with the saws and notches in the upper guide,

and though this socketed plunger may have a vertical reciprocating movement it is suitably held against rotation, so that the notches and saws will always be on a vertical line with each other.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. In combination with a series of radial cutters, a socketed plunger, for the purpose set forth.

-2. In combination with a series of radial cutters, a guide therefor and a plunger having the upper end socketed, substantially as set forth.

3. In a device for cutting recesses or hatches, a series of cutters secured to suitable frames so as to project radially inward with central plungers or guides, for the purpose set forth.

4. In combination with a cutter consisting of upper and lower rings, saw-blades having inwardly tapered edges, a guide with recesses .on a line with said blades, and a socketed.

plunger with similar recesses, substantially as set forth.

5. The combination, with a radial series of saw-blades or cutters B, of rings for holding the upper and lower edges of said blades, a guide 0, adapted to move between the blades and in the rings, a plunger I), having a socket in its upper end Within which the article to be notched is placed, and longitudinal grooves into which the cutting-edges of the blades B pass, substantially as and for the purpose set forth.

{5. As a new article of, manufacture, a cutter, for the purpose set forth, consisting of a series of blades arranged radially and equally disposed, and an additional blade, as b, substantially as set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
