Specification forming part of Letters Patent No. 149,480, dated April '7, 1874; application filed March 16, 1874.

CASE A.

To all whom it may concern:

Be it known that I, JOHN C. HURCOMBE, of the city, county, and State of New York, have invented a new and useful Machine for Clasping Metallic Bindingltings or Eyelets to the Ends of Umbrella Gases and the Gores of U111- brella-Covers, of which the following is a specification:

My invention consists, broadly, of a machine for claspin g metallic ring-binders'to the ends of umbrella-cases and to the ends of the gores of umbrella-covers, so as to confine the fabric between the edges of the metal binder, such machine consisting of an anvil carrying a spring or yielding poppet-holder for the metal binder, and mounted upon a hollow heatingpost, so as to retain and present the binder to the action of a clusping-hammer, the heatingpost serving to heat and hold the article while being united with the binder, and the spring poppet-holder performing the function of securing the clasped binder upon the anvil, to hold it in position to allow the umbrella-case to be turned right side out in effecting its reresult from its removal in a cold condition.

In the accompanying drawings, Figure 1 represents a vertical section of my ring-binderclasping machine, with a metal ring in position to bind the edges of an umbrella-case; Fig. 2, a similar view,showin g the metal binder clasped upon the fabric; Fig. 3, a similar View, showing the metal clasped binder as held by the spring-poppet to turn and remove the case from the post; and Fig. 4, an elevation of the anvil and spring-poppet.

A hollow metal standard, A, supports at its upper end a swinging hammer, B, by center screws, which may be adjusted and secured by lock-nuts. This hammer is held up by a spring, 0, and forced down by a treadle, D. (Shown by dotted lines in Fig. 1.) At the base this standard joins with a hollow iron post, E, by means of a heater, F, so as to make communication betweenthese twouprights, for a purposeto be presently stated. The upper end of the post E carries a hollow cylinder anvil, G, within which is placed a spring-poppet, H, or detent, to receive and hold the metallic ring-binder I in position upon the anvil G while being secured to the fabric, and also to hold it after such fastening of the ringbinder, to allow the case to be turned right side out, the case being fitted over the anvil Gr and heating'post E with the glazed side turned in, as shown at X in Fig. 1. This spring-poppet H is in two halves, and when closed has the form of an acorn, with an annular shoulder or recess, a, at the base and just above the anvil in the normal position of the poppet. Its stem is a U-spring, b, and rests upon a spiral spring, '0, in the hollow post to keep the poppet projected from the anvil when not under the action of the hammer B, the end of which has a concavity or socket, (I, which, in its descent upon the poppet, receives its closed end in the socket, and carries the poppet down under the blow, so, that the metallic ring-binder, which surrounds the poppet and rests upon the annular seat 0 of the anvil, iscla'sped with the fabric. This binder I is a ring with a groove round it formed by the concave sides, between which the fabric is held and clasped, but an eyelet and washer may be used with the machine as well. In applying the ring-binder it is first pressed over the poppet H to hold it on the anvil G, and the case X is then drawn over the poppet, binder, anvil, and post, and a string drawn round the end of the fabric to force and hold it in the groove of the binder, when the hammer is depressed by means of the treadle, or other device, and the curved sides of the ring are clasped and forced hard upon the fabric to form a metal binding to the end of the case. The retreat of the poppet under the hammer carries with it the annular groove or shoulder a into the anvil, so that it cannot catch over the ring while resting on the anvil or receiving the blow of the hammer, as the inside swell of the grooved ring is larger than said shoulder. The fastening of the fabric having been made between the flattened sides of the ring, the poppet rises through the ring I, and, the shoulder a, of the poppet passing above the ring, the sides of the poppet open, and the flattened ring is held upon the anvil by the said shoulder a, toallow the case to be turned right side out in removing it from the post. The function of the poppet to catch and hold the ring is automatic, as its U-spring spreads the two parts asunder as the spiral spring forces it up immediately upon the ascent of the hammer, as shown in Fig. 3. The removal of the case in this way from a cold iron post would, however, endanger the cracking, defacing, and tearing of the case; and this I prevent by the employment of a heated hollow post, to impart a gentle heat to the case, and allow it to be drawn off quickly, and without loss or injury, The post E is heated by water from a boiler, F, connecting with the post and the hollow standard A, and the heat is applied in any suitable way, either by oil, gas, or steam. In the example shown, the heat is applied by means of a pipe, L, opening at the boiler F, and extending up and out at the side of the standard A. Anopen pipe, M, extends from the post E- to the standard A, through the boiler F, for the purpose of maintaining a circulation of the water within the post upon the principle of the siphon, to give heat enough to keep the case gently heated, and make it soft and pliable for being turned over the post, and thereby save a loss of about five per cent. in tearing and cracking the cases, besides the inconvenience and loss of time in handling cold stiff cases, which would be occasioned in putting them on and taking them off a cold holding-post. The descent of the hammer is regulated by a set-screw, N, adjusted by locknuts n, so as to compress the ring tightly upon the fabric. The ascent of the poppet may be regulated by a stop on its stem, to bring the annular shoulder a always above the anvil to insure the holding of the clasped ring. The anvil and poppet may be removed and replaced by others of different sizes. The water is introduced at the top of the standard, and the top of the siphon-pipe should be belowthe water-level therein, as shown in Fig. 1, so as to make the circulation.

I claim 1. The combination, with the anvil in a machine for clasping metal binders to umbrella cases and covers, of a yielding poppet, H, whereby the binder is held for the clasping action of the hammer.

2. The combination, in a machine for clasping the metal binders of umbrella cases and covers, of a holder-poppet, H, for the ringbinder, an anvil, G, and the holding-post E for the fabric.

3. In combination with a hollow anvil, a split spring-poppet, H, to hold the ring-binder in place, substantially as described.

4. In a machine for elaspin g metal binders to umbrella cases and covers, a split springpoppet, H, constructed with a shoulder or reeess, a, whereby the ring-binder is held to the anvil G, to allow the case to be turned right side out in removing it from the holding-post.

5. In a machine for claspin g the metal binders to umbrella covers and cases, a hollow heated post or holder, E, for the umbrella-case, for the purpose stated.

6. The combination of the hollow heated post E with the hollow standard A and the boiler F, substantially as and for the purpose described.

7. The siphon-pipe M, in combination with the heating-post, the boiler, and the watertank, substantially as described, whereby the hot water is caused to circulate from within said post.

8. The combination, in a machine for clasping metal binders to the ends of fabrics, of the anvil, spring-poppet, holding heating-post, hammer, water-tank, boiler, and circulatingpipe, substantially as described.
