IMPROVEMENT rN :inner-MAKING MACHINES.
The Schedule referred to in these Iietters Patent and makingpart: of the s ame To all whom it may concern Be it known that I, HORACE C. BRADFORD, of the city and county ot lrovidence,`and State of Rhode Isand, have inventi-:dy a certain new and useful Improvement in Machines for Making Metallic Eyelets; and I do hereby declare that the following specification, taken in connection with the drawings furnished, and tbrming a part of the same, is a true, clear, and exact description thereof.
My invention consists in the use of a revolving` milling-tool or cutter, so arranged, in relation tO the cutting and forming die, that as the eyelet-cup is formed therein, its end is cut away by the millingtool, thus perfecting the cyelet at a single operation of themachine. l
lieti-rence being had to the drawings herewith- Figure 1 represents, in perspective, the main features ot' a horizontal-acting eyelet-machine, with my improvements attached.
A is the drivingshaft.
B is au eccentric on shaft A.
C' is an eccentric-rod.
D is a reciprocating slide, attached to and operated by the cccentric-rod.
E is a male die or punch, for forming the eyeleteup, and is attached to the slide D in nan obvious manner.
F is the female die, formed to suit requirements, (as regards size and sha-pe ot' the eyelet desired,) and to which the male die E is accurately adjusted.
The rear ot'V this die F is recessed, which, with the front po1iion,i`orn|s an opening through the die-plate, -so that Iwhenthe eyclet-cup is formed, and still remains on the cnil ot' the male die E, it shall protrude into the recess, a distance equal to and by preference slightly greater than the thickness ot' the eyelet-metal at the round end ofthe cup.
G is the milling-toolor cutter, which involves the main feature ot' my invention. f l1t, is connected with an arbor, operating at right angles with.- the driviiw-shaft A, and from which it may receive motion, by any oi' the well-known modes ofconnmmication.
1t is to be remembered in this connection, that the die for cutting the blanks or disks i'roin sheet-metal, v
with the necessary feeding-device, is not. shown, nor is the mechanism for clearing the eyelets from the male die, as neither of these relates to my present invention.
` Figure 2 represents the same as in fig. 1, in vertical longitudinal section, and exhibits all the parts in their relative positions. Said parts are lettered' as in iig. 1.
Figure 3 represents the face of the cutter or milling-todi G..
Figure 4 represents the cutter vG in section, and
exhibits its internal structure.
1t will be seen that its centre isidrilled out from'.
the cutting-end inward. The aperture is ot' 'a regular and even diameter for a short distance, and then' en-` !arges on a taper to the rear. y
The purpose of this aperture is Ato receive the circular tops ot' the eyelct-cups removed by the cuttu'.
Ithas a regular diameter for a short distance, in order to adniit ot' the sharpening of the cutting-edges of the milling-tool, as they might wear from time to time,and thus require it. l
The gradual enlargement Ortapering of' the aperture, eiectually prevents the cuttings from getting clogged-therein, and facilitates a ti'ee discharge of the same through the opening provided therefor in the.
arbor.
The operation of my improvement is as follows: The dies having been accurately adjusted, the cut.- tcr G is advanced intoY the recess at the rear ot' the die F, until at a point distant from the rounded shoulder in said die, equal to the length Ot' the eyelet.
desired.
As the die or punch E advances with an eyeletcup, just formed, or being formed, itr presses the mund end thereof into the cutting-aperture ot' the revolving'tool G,which cleanly' and instantaneously removes the end, thus finishing the eyelets` by the time the die E next recedes, the same Operation being repeated at every revolution of' the machine.
rlhe round ends ot' eyelet-cups have heretofore been removed, either by the use ot dies provided with ci1t ting-shoulders or by grinding, the latter operation being done in` a separa-te machine, by means of a` grinding-wheel and an endless beltfwith pertbrations for receiving and holding the eyelet-cups during the process ot' grinding.
The use ot` dies with the cutting-shoulders is open to many objections, the principal lot' which is the 'necessityof using a very sott, tine, and expensive metal, which will stand the various cuttings without tiacture, and yet be ductile' in thelinished eyclet. Should l 'as well as to that in connection with which kit is herein described and shown.
I Having thus described my invention,
I claim as new, and desire to secure by Letters APatent of the United 4Statesl. The combination ot' the dies E and F, or their equivalents, with the revolving cutter" G, or its equiv alent, arranged relatively to eachv other, substantially as herein described, for the purposes speciiied.
2.-Therevolving cutter G, with its open centre constructed to operate substantially as described, for the purposes speciiied. v
