Innovations in wire drawing machines.

Patented in the German Empire on September 18, 1877.

The purpose of this invention is to construct a wire drawing machine so that all parts able to withstand the necessary pull and great strength, simplicity of construction and Ease of assembling multiple machines is achieved. Another purpose pursued by this invention is to produce a wire drawing machine which in all its functions is completely and utterly automatically active and in which all parts, in themselves perfect, fulfill all the functions required for wire drawing. Next I aim is the driving mechanism connect them to the drum by an improved prong in such a way that the same easily combined by hand or automatically by means of the drive mechanism and from can be detached from each other.

The invention consists in the peculiar construction of the frame of a wire drawing machine, whereby the drive shaft, tine and drum are all carried by the same frame, which is so constructed that it can withstand all necessary drafts, and also the moisture, so that it can cannot warp. Furthermore, the invention resides in the peculiar composition the main drive shaft and the beveled gears, the tine and the drum, everything firmly attached to the frame so that each frame contains a complete machine. The relative position of all parts remains unchanged at all times; a machine can that is, to whichever place they are shipped or transported, where only the necessary Driving force needs to be applied to put them into operation. To further exist the invention in the peculiar arrangement of the prong, making the drum with the drive mechanism is connected and detached from the same. It also consists in that peculiar arrangement of the two thumbs with the main drive shaft, one of which is on one lever on which the drawing pliers is attached and the other on a wire sharpening device works. It also consists in the peculiar mechanism by which the drawing machine automatically shut down if the wire breaks or the wire unwinding drum is in disarray device and in the arrangement of the safety brake, through which the wire on the drum is withheld, as detailed below.

In the drawings, AA are cast iron side frames that are provided with the support beams BB , in which the main drive shaft rests again. C is the cast iron front plate on which the transverse plate C ¹ sits, which is either cast in one piece with the front and rear plate C ² or firmly fastened between the two by bolts; The whole thing is screwed tight to the end frame AA in such a way that it forms a firm and solid structure that is not subject to wobbling and in no way yields, as is the case with the heavy wooden tables that have hitherto been used. In the plate C ¹ the shaft to which the drum is attached has a fixed bearing which is cast with the plate. C ³ C ³ are front and rear longitudinal plates, fixedly attached to the side frames, and to these plates C ³ , the plate C ^{4 is} firmly screwed on or cast in one piece with the same, thus forming the base bearing for the vertical shaft and at the same time serving as a support for the bearing of the main shaft in the center of the machine.

The side frames A, the top panels C, C ¹ and C ² can be filled in with wood to form the table and, since the side frames are arranged to accommodate two ends of the panels, a number of double wire drawing machines can be used Attached end to end and operated by a main drive shaft.

The mechanism used for the exercise of the various functions of the machine consists of the main shaft α, which can be driven by any moving force and to which the gear is attached, which, engaging in the horizontal, conical gear a ² , this latter set in rotation, b is the vertical shaft, at the upper end of which the drawing passage or drum b ^{i is} attached. The shaft b goes through the conical gear a ² and is held by a bearing on the plate C ⁴ ; the conical wheel α ² can therefore rotate on the shaft b because it sits loosely on the same, while the prong b ^{2 is} firmly attached to the shaft b .

The KTrnkVV, which can move like a character, is attached to the conical gearbox ^ α ^{2, as}

is shown in Figures 8 and 9. The pawl c is provided with a round projection c ^l , shown enlarged in Fig. 10 and mounted so that when the lever d is lifted, the loose friction roller d ¹ comes into contact with the projection c ⁱ and the pawl with the pin at the disk ί> ² as shown in Figure 9; When the lever d is lowered, the roller d ' comes into contact with the rear end of the pawl c, which is movable in the manner of a character, releasing it from the disc £ ² and preventing the rotation of the pulling passage. E is a spring that serves to hold the pawl c in the position to be brought into by the lever d ; it is shown as coming into contact with the end of the pawl, but this contact can take place anywhere else as long as the pawl is held in the desired position. In this way, one, two or more pawls that can move like a character can be attached to the upper surface of the conical gear a ² and one, two or more pins can be attached to the disc ί> ² at regular or irregular intervals and used to to connect and disconnect the driving mechanism to and from the disc, and thereby to and from the pulling passage, as a result of the raising or lowering of the lever d.

Instead of attaching the pawl c to the bevel gear, the same can be attached to a special disc, which is driven in a suitable manner, and thereby the driving force can be connected to and disconnected from the machine by raising and lowering the lever d . This ensures the prompt action of the disc and prevents the sticking that circuits are usually exposed to.

The thumb / is attached to the main shaft α in order to give the lever / ', the upper end of which goes through an incision in the front plate C , an alternating or oscillating movement; to the upper end of the pulling jaws are connected, as shown in Fig. 1 is shown by dotted lines and by the same one of direct train is applied to the first part .eisen the wire through the D jjrcMafs to pull secured to a sufficient length is to attach the same to the drawing passage b ', the cranked passage holder / ² being easily adjusted to the new direction of the wire.

/ The passage holder is attached to a plate by a bolt that goes through a cut in the front plate C to enable the passage holder to rotate on the bolt and act alternately in the notch while the whole ί in the front end of the incision is held by a> spiral spring. When the machine is set in motion, the pull of the wire on the passage creates a pull on the coil spring, thereby enabling the passage holder to slide in the incisions. Once the wire breaks, draws, following the easing of the train, the coil spring to Durchlafshalter forward and because it is desirable, that ^ when this happens, the machine will automatically set silent, the lever / ³ is on the lower plate of the Durchlafshalters attached and provided at its lower end with a pawl / ⁴ which, if a j. Pull is exerted on the void , over the foot /, step lever / ⁵ , which is attached to the rear part of the frame like a charm and protrudes from the front of the machine and is connected to the moving lever g . The latter reaches as far as the lever d which moves the prong and raises and lowers it; As soon as the pull continues, the notch in the pawl / 'is pushed over the footstep / ⁵ and enables the same to climb up and thus, by means of the lever g , press down the lever d and the rotation of the drum by holding the lever d with the pawl-like pawl c brings into contact. The former of these positions is shown in FIG. 5 and the latter in FIG. By virtue of this arrangement, the machine is automatically shut down as soon as the wire breaks.

If the wire breaks suddenly, it is easily possible that b on the drum ^l wound part DAF unrolls and when the wire is thick, the damaged working and the machine. To prevent this, I bring the movable brake charnierartig h with the drum into contact so, that they the wire due to the pressure of the spring holding ^l h. When the same is to be released, I press the footstep h ³ , which acts on the brake h through the lever h * and releases it from the wire, as shown in FIG. 4.

The wire wound on the downdraft is at risk of being disordered, and the pull applied is capable of breaking or otherwise damaging the downdraft and kinking the wire. In order to avoid this, I attach the downdraft on the character-shaped frame i . The downdraft z ' ¹ is carried by a vertical shaft which passes through two bearings which are fixed to the frame i and which is provided with the lifting arm z' ² which rests against the spring i ³ and is provided with a pin which extends up to the lock / ⁴ , so that, if an unusual increase in force ^{takes place on the downdraft z 1} , the pin on the lifting arm z ² pushes the pawl / ⁴ inwards and enables it to be inserted into a cutout on the footsteps / ⁵ to enter and thereby enable it to climb up and to act through lever g on lever d , the rotation of drum b '

to stop and prevent damage to the downdraft.

The machine will therefore come to a standstill by itself, both if the wire breaks and even if the wire gets messed up on the downdraft.

Every time the wire breaks, the end of the wire has to be pointed so that one can enter the void. This currently takes a long time. To get around this, I put a wire-sharpening device on the machine, consisting of scissors, with the cutting tool attached so that it cuts a long point. KK are two chamier-like movable jaws that are provided with bevelled cutting tools. One of these jaws is firmly attached to the front plate C and the other is provided with a lever, the end of which engages the thumb K ¹ , which is attached to the main drive shaft. A reciprocating or oscillating movement is hereby transmitted to the cheek; the wire is brought between the jaws and a long, pointed wedge is cut from them. If necessary, two or more such wedges can be cut by partially turning the wire, so that the pointed end can be easily inserted into the void.

This sharpening device saves time and makes the machine easier to use.

This wire drawing machine is used as follows:

After a ball of wire has been brought onto the downdraft 2 ', the worker brings the end into the sharpening device, where it is sharpened. Then he lets the sharpened end pass through the void, grasps it with the pliers attached to the alternating lever / 'and pulls enough wire through it to be able to attach it to the drum b'. Then he presses the footstep / ⁵ down and brings the latch together with the prong b ² , which gives the drum a rotating movement and thus pulls the wire through the void, while the brake h keeps it firmly on the drum and the one on the void The tension exerted holds the lock / ⁴ over the footstep until the whole wire has passed through the void or until it breaks or gets into disorder on the downdraft, in which case the machine is momentarily kept still, by the fact that the footstep is free and again by the lever d the prong b - freed.

The machine is completely automatic, it is strong and simple in its construction and Application and highly efficient.
