- Application inea December 9,1893. serial No. 493,230. (No'model-t To all whom it may con/cern.: Y

Be it known that I, WILLIAM CANNELL, of Lynn, Essex county, Massachusetts, have invented certain new and useful Improvements 1n Ferrule- Machines, which improvements are described in the following specication and are illustrated by the accompanying drawings.

My invention'is a combined drawing-press and trimmer for the manufacture of ferrules, and. other like articles. In the construction of the same it is` my object to combine in a superior manner, and in a single machine, all

'the mechanism which is necessary for performing the several operations involved in convertingl a strip of sheet metal `into finished ferrules. To accomplish this object, I use a doub1e-action drawing-press, which is pro# -v1ded w1th primary dies and punches, in the usual manner, and which is also`provided with aseoondary die and punch, in combination with a trimmenand with mechanism for transferring the partly finished ferrules between the primary and the secondary dies.

The best manner in which I have contemplated applying the principle of my invention, is shown in said drawings, in Which- Figure l 1s a side elevation of a ferrule machine, which is constructed upon that principle. Fig. 2 is a front elevation of thev same.

Fig. 3 is an enlarged view of a portion of the same, partly in front elevation, and partly in vertical section; and Fig. 4 is a plan ofthe transferring mechanism in detail.

The machine which is exhibited in the draw- 'ings includes the essential parts of a common double-action cutting and drawing press,

namely: the main shaft, which is denoted in punch, the drawing slide 4,l reciprocating in' slide 7, and holding the drawing punch 5 by` Ymeans of cap 6, a crank ,on the main shaft 27,

carrying apitman 29, which is connected with fdrawing slide 4-by a toggle joint 69, the blanking die '9, the drawing die 10, and the spring stripper 11, which is placed in an aperture position, adjustable by means of nut 47. On

holder 33 is a rotable brass shell 40,`having a neck, which is formed by the circumferential groove 46. Anut 43, on the same holder 33, is providedv with a bridle 45, taking into lgroove 46, and with peripheral teeth 44, en-

gaging a rack 50, which is held up to such engagement by a bridle 52. A combined shell and pulley 41,y keyed to shell 40, andarmed at its lower extremity with a steel cutter 42, is driven at high speed by a belt 49. Within the holder and die, 33 and 34, is a springseated knockout 48, whose head is in apposition with lever 54. The inner end of this lever is fastened loosely in a hole in slide 7, and the outer end of the same projects through a guiding plate 72, on the face of `that slide, for the purpose of being alternately engaged and disengaged by latch 53. An adjustable plate 36, which isseated in bed-plate 15, as shown in Fig.r 3,' holds a secondary cutting punch 35, stationary under die 34, in a hole, which contains a stripper, consisting ofthe annular rubberv spring 37 and the annular steel cover 38.

The main element of the above-mentioned transferring mechanism is the 'turret 12, which is shown in Figs. 3 and 4. 'This turret, which is provided with a predetermined number of receptacles, or peripheral pockets, 13, is conveniently located on thetoplof plates 15 and 36, and-is surrounded by plate 32. The sameis provided with a shaft 16, which is journaled in a vertical position in bed-plate 15, and is rotated intermittently by means of ratchet and pawl, 17 and 18, so that pockets 13 pause in succession under punch 5, and also under die 34. Ratchet-wheel 17 has a sleeve, which is fastened to shaftv 16 by pin 21; and pawl 18 is carried by lever 19, which turns upon the sleeve of the ratchet-wheel17, being held thereon by collar 20.

A rockshaft 22, which is driven bya crank disk 24 on the mainA shaft 27 by means of a pitman 56 and arm 23, has three arms 25, 51

and 58, which are shown in Fig. 1. Arm 25 is connected by a pitman 26 with the-lever 19, for the purpose of intermittently rotating the turret 12; arm 51 is connected by a pit man 59 with the rack 50, for the purpose oi turning the nut t3 alternately up and down upon the die-holder 33; and arm 58 is connected by a pitman 55 with a bar 57, for the purpose of operating the feed mechanism, which remains to be described. The feed mechanism is a carriage, reciprocating upon bolster-plate 1, and consisting of two guidingl slides 14, a flat plate G0, by which slides 14 are joined together, and a swingi-ng bar 61, which is capable of automatically gripping in position upon plate GO the ribbon orstrip of brass, 67, from which ferrules are to be formed.

It remains to mention the tripping mechanism, by means of which the machine is stopped in case of accidental failure of the primary punches to perform their functions. In plate 32 is set a sliding plate 62, which is adapted to slightly enter the mouth of any one of the several pockets 13 which may be presented empty, as shown iii Fig. 4:. This sliding plate is connected by lever G3 and rods 64 and 65, with a trippingr lever, not shown iii the drawings, acting upon a key 70, by `which pulley 66 engages the inain shaft 27. This tripping mechanism, which is not fully shown in the drawings, is not peculiarin any other respect than that of being capable ot' being brought into action by the absence of;

a ferrule from that particular pocket 13 which is for the time being directly under die 34.

Such being the construction of my improved feri'ule machine, its inode of operation remains to be described.

The strip of brass or other metal, G7, of suitable width and of indefinite length, being the stock, which is to be worked up intofer-` rules, is Iii-st inserted by hand between parts 60 and 61 of the described intermittently re` ciprocating feed carrier, so that a portion of the strip 67 is brought into position under the primary punches 3 and 5. Then, as pulley 6G begins to turn, slide 7, descending through the position in which the same is shown in Fig. 2, and into the position in which the same is shown in Fig. 3, presses the blankin g punch 3 into die 9, and thereby cuts from the strip, or ribbon, 67, a disk or circular blank, 63. Meanwhile, and until the machine is fully underway, the described tripping mechanism is held inoperative by the hand of the operator. After the described formation of blank G8, the same is held in the bottom of die 9, between punch 3 and die 10, While cams 28 are on the dwell. Then, as pulley 66 continues turning, the main crank, operating through pitman 29, forces the drawing punch 5 down into die 10; and blank 6G is thereby drawn in the usual manner into the form of a cylindrical ferrule, closed at the bottom, and is carried down through the annular spring strip per l1 into a pocket 13 of turret 12. Then slide 7 ascends, while the described ferrule with closed bottom, being preventedby stripper 11 from accompanying punch 5 in its up ward movement, is left with its mouth open upward in that pocket. Next, turret 1 2, being iinpelled by rock-arm 25, th rough pitinan 26, lever 19 and ratchet and pawl, 17 and 18, is rotated one step, namely, through an angle representing the distance between two adJacent pockets 13; so that such partly made ferrule is carried away from the path of punch 5, and the next pocket 13 is brought to rest empty under that punch. As the machine continues working, all the described steps are repeated as many times as are necessary to bring the first-mentioned pocket and feriule into position under die 3ft. Then at the next followingdescent of slide 7, die 34, entering the last-mentioned ferrule from above, lforces the latter down onto punch 35, as shown in Fig. 3, so that a hat circular plate, the disk 71., is cut from the bottom of that ferrule. Next, the rack 50, being propelled by rockarin 51, turns the nut 43 down upon the dieliolder 33, and thereby depresscs shell 4:1, so that the revolving cutter A12, being pressed down into the upper edge of the ferrule, trims off all irregularities, and leaves the tei-rule finished. After cams 28 have turned so far as to allow slide 7, drawn by springs 30,110 begin to rise, the knock-ont 48, being actuated by the guided lever 54 and the stationary latch 53, pushes disk 71 out of die 34C, leaving that disk loose in the ferrule. By means o f the spring strippers 37 and 38, the ferrule is disengaged fiom-piinch 35, and is restored tothe same position which it previously occupied in pocket 13. The completed ferrule is afterward discharged from the turret 12, and from the machine, through a hole, which is not shown in the drawings, leading from a point under the path of pockets 13, through the bedplate 15.

Whenever, during the opei'ation of the niachine, a turret 13 is presented to slide 62 empty, and accidentally unoccupied by any ferrule, that slide automatically enters the mouth of that pocket; and by this movement the before-mentioned tripping mechanism is brought into action, and pulley 66 is let loose upon shaft 27 by the withdrawal of key 70. So the machine stops, awaiting the attention of the operator.

Such being the construction and operation of my improved ferrule-machine, I claim as my invention- 1. In a machine for the manufacture of ferrules, or other like articles, a primary cutting punch and die, a drawing punch and die, a Secondary cutting punch and die, a trimmer, and mechanism for operating such punches, dies and triminer,in combination withtransferring mechanism between the primary andsecondary cutting punches, substantiallyias and for the purpose specified.
