PUNCHING-MACHINE.

Specification of Letters Patent.

Patented Mar. 20, 191 7.

To all whom zt may concern.'

Be it known thatL'I-IENRY LEFEBVRE, a citizen of the United States of America, residing at Douglas, in the county of Cochise and State of Arizona, have invented certain new and useful Improvements in Punching- Machines, of which the following is a specication, reference being had therein to the accompanying drawing.

This invention relates to punching machines and has for its object the production of a simple and eicient punching machine for facilitating the keeping of the twyers open to permit the airV to pass freely into the converter while the machine is in operation.

Another object of this invention is the production of a simple and eicient-punching device which may be easily and conveniently attached to a smelter so as to permit the punching bars to pass through the twyers and efficiently operate to keep the twyers free from obstruction.

With these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of i parts, as will be hereinafter fully described andl claimed.

In the accompanying drawings Figure 1 is a top plan view of the appa' ratus.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end elevation.

Fig. 4 is a longitudinal section taken on line 4 4 of Fig. 1.

Fig. 5 is a section taken on line 5-5 of Fi F ig. A6 is a horizontal section through a portion of theconverter, showing the manner in which the punching bars extend therethrough. n

Fig. 7 is a horizontal section through one of the plunger cylinders, showing the manner in which the same is supported upon the supporting framework.

Fig. 8 is a transverse section through the frame and bar for supporting the punching bars.

.Fig 9 is a section taken lon line 9 9 of Fig. 8.

Fig. 10 is a vertical section through one of the punching bars supporting members, showing the manner inwhich the punching bars are secured thereto.

Fig. 11 is a detailed perspective of one end of the punching frame.

Fig. 12 is a transverse sectional view through the inner end of the punching frame, showing the manner in which the same is secured to the converter.

' Fig. 13 is a section taken on line X-X of Fig. 10.

Referring to the accompanying drawings by numerals it will be seen that 1 designates the converter which is supported upon the concrete or other suitable support 2. The converter 1 is adapted to be operated by mea-ns of a motor 3 carrying a driving sha-ft 4, which shaft 4 isprovided with a worm screw l5 meshing with a worm wheel 6. The worm wheel 6 is carried by a shaft 7, the shaft 7 carrying supporting rollers 8 as clearly shown in Fig. 2. Other idle rollers 9 aresupported upon the base or support 2 forpthe purpose of supporting the converter l, above described. y'lfhe'wheels or rollers 8 and 9 engage the supporting wheels 10 as` illustrated clearly in Fig. 2.

The converterl isprovided with the usual twyers 11 as illustrated in Fig. 4, through which twyers 11 are adapted to extend the punching bars 12 and 37. TheA usual wind box 13 is employed and communicates with the twyers 11 by means of'a communicating passage 14, as illustrated in Fig. 4.

The frame 15 is supported upon one side of the converter and is provided with a pair of side portionsor rails 16 of a channel iron construction, each rail 16 carrying at its rear end a block 17, which block supports an overhanging plate* 18 which is securely held in engagement with `the block 17 by means of a bolt 19. This plate 18 is adapted to firmly clamp over the .transversely eX- tending supporting bar 2O of the converter for supporting the inner end of the frame 15 in engagement with the converter. 1t should be understood that the frame may be easily and conveniently removed from the converter 1 when so desired by means of releasing the plates 18 from the supporting bar 20 and detaching the turn-buckle supporting mechanism hereinafter described.

The forward ends of the frame 15 are arranged in converging relation, over which ends lit the radiating arms 21 of the operating cylinders 22. These arms 21 are provided with rearwardly extending ears 23 for fitting in iirm engagement with the frame 15, the ears 23 being secured to the frame 15 by means of the rivets 24.

Two or' these cylinders 22 are employed, one cylinder being placed above the other, as illustrated in Fig. 4 of the drawings and a piston 25 is placed within each cylinder which piston engages

piston rods

26 and 26 as illustrated in Fig. 4. The outer ends of the cylinders 22 are closed by means of the cylinder heads 27, illustrated in Fig. 4 of the drawings. Communicating pipes 28 are connected to a suitable source of air or water supply for supplying suitable driving power to the cylinders 22 for operating the piston heads 25. The pipes 28 communicate with the respective ends of the cylinders to control the admission and discharge of water or air from the cylinders 22.

1t should be understood that any suitable driving power may be employed for the purpose of operating the piston rods 26, without departing from the spirit of the invention.

The frame 15 is provided upon each side thereof with an eye 29 and a turn-buckle rod 30 engages each eye 29, the upper end of each turn-buckle rod 30 being provided with a hook 31 for engaging the eyes 32 formed upon the converter 1. It will therefore be seen that these turn-buckle rods 30 will constitute an efiicient support or brace for the frame 15 and when it is desired, the frame may be readily released from the converter by detaching the plates 18, as above described, and also the turn-buckle rods 30 for moving the frame 15 out of engagement with the converter 1, thereby permitting the converter to be operated without being interfered with by the punching machine.

The frame 15 is provided upon one face thereof with an upper track 33 and a lower track 32. rlhe upper piston rod 26 engages a plurality of ears 34, which ears are carried by a transversely extending bar 35 having its ends traveling in the track 33. A plurality of heads 36 are suspended below the upper bar 35 and a punching rod 37 is supported upon each head 36, being firmly held in engagement therewith by means of the clamping bolts 38. The heads 36 are held in detachable engagement with the bar 35 by means of the nuts 39 which are threaded upon the bolts 40 of the heads 36. The punching bars 12 pass through the guides 41 carried by the supporting plate 42 of the converter frame so as to guide the punching bars 12 through the twyers 11 as above described for keeping the twyers clean and tree to permit the air to freely pass therethrough while the machine is-in operation.

The lower piston rod 26 is secured at its outer end to a transversely extendingbar 43 which supports a plurality of heads 44 to which heads are secured the punching bars 12, as clearly shown in Fig. 4. These punchingbars 12 pass through the guides 41 carried by the converter 1, the guides of the lower punching bars being arranged in staggered relation with respect to the guides for the upper punching rod. The transversely extending bar 43 travels in the lower track 33 as clearly illustrated.

It is necessary to employ different series of punching rods in .order to prevent too much air coming out of the converter at one time, for the reason that air is bound to esvcape during the punching operation. 1t of course is obvious, that if all the rods were operated at one time, hardly any air would pass through the converter, while in operation. Therefore, by punching one half o`f the rods at a time, about one half of the blast is effective.

What I claim is 1. A punching device of the class described comprising a frame, said frame provided with an upper and a lower track, a transversely extending bar working in each track, a series of punching bars supported upon each transversely extending bar, each set of punching bars being arranged in staggered relation, and means for reciprocating said punching rods upon said frame.

2. A punching machine of the class described comprising a frame, an upper and lower track, a transversely extending bar secured to each track, punching rods secured to each transversely` extending bar, the bars carried by the upper and lower transversely extending bars being arranged in alternate spaced relation, means for reciprocating said transversely extending bars upon said track, and guiding means for directing said punching bars into the converter.

3. In combination with a converter provided with twyers, of a frame, a plurality of tracks carried by said frame, a transversely extending bar working in each track, punching bars secured to each transversely extending bar, and said bars working alternately with respect to each other for causing one half of the air blast to remain eiective during operation.

4. In combination with a converter provided with twyers, of a frame, a plurality of tracks carried by said frame, a transversely extending bar Working in each track, punching bars secured to each transversely extending bar, punching bars carried by one transversely extending bar fitting between the'punching bars of the other transversely extending bar, and means for alternately reciprocating the different series of punching bars for causing at least one half of the air blast to remain eeotive during operation.

In testimony whereof I hereunto aHiX my signature.

HENRY LEFEBVRE.
