lacs; Serial To all whom it may concern: v v Be it known that I, CLAES A. Svnnsson, a citizen of the United States of America, re

siding at Bulialo, in the county of Erie State of New York, have invented a new and useful improvement in Wire Guides and Cutters, of which the following is a specification.

This invention relates to a device designed inoreespecially for guiding a continuous piece of wire from a suitable feed device to a mold in which a soft metal seal is cast upon the end of the wire, and for cutting the wire into proper lengths. The invention, however, is not limited to that particular, use.

A seal-casting iriachine to which the invention is applicable is shown and described "in another application "for patent filed me October '2, 1901, Serial No. ,79,02t, of which the present application, is a division. I

The principal object of this invention is the provision of a simple and reliable guiding device which will positively directand present the advancing end of the wire to a mold or other desired device or-d estination.

A further-object is to so construct and arrange the wire-guide that it serves 'at the same time as a cutter for severing the wire into suitable lengths.

Similar l rs of reference indicate core po ding parts throughout .the several wiews.

A is a suitable bed or table upon which the i'nachine' issupported. ,The frame of the machine shown in. the drawings consists of an upright longitudinal beam A stiffened by ribs or flanges and-arranged centrally of the machine. Located centrally on this frame is a sealca sting mold B, and above "it is a delivery nozzle 0 for the'rnolten metal which is connected with a suitable melting pot O. The special construction of the lastnarned parts forms no part of the present invention.

.Dfindica'tes a feed device for delivering a continuous length of wire to the mold, so

as to cast one end of-the wire in the seal.

This feed-device preferably consists of a pair of horizontal feed-rollers arranged at the front end of the machine and located at the proper distance apart to receive the wire between their peripheries and feed the same forward. These rollers may have plain or smooth faces, but when the wire is to lie crimped or corrugated as in some kinds of seals, th e peripheries of the rollers are provided with vertical teeth or corrugations, as shown in the drawings. erably taken from a continuous coil wound upon a reel, not. shown in the drawings, and

isdirected between the feed-rollers by a Sta-- -tionary horizontal guide-tube E arranged in line with the meeting sides of the rollers.-

This guide is supported in a standard 6 rising from a bracket 6 secured to the stationary frame, as shown in Figs. 1 and 4.

- On the rear side ofjthe .feed-rollersis located a second stationary wire guide F consisting preferably of a block having a The wire is prefstraight vertical rear face and a guide-eye or channel 7" for the wire arranged in its top in line with the guide-tube E. The upper side of this guide eye is preferably formed by a movable plate f Fig. 7, which is.capable of sliding vertically upon a stud f secured to the block F to permit the wire to be removed in case it should bind in' the guide-eye by becoming bent or kinked. The

covering;plate f is held down in place by a .set screw 7, or other means, and 111 its depressed position interlocks with a stud or bored lines'in Fig. 1.

end of the plate, as shown in Fi .9, thereby preventing turning of the plate on the stud f Between the guide-block F and the sealcasting mold or other part designed to receive the wlre, is arranged a wire guide and cutter G which is adapted to directthe wire mold and the rear wire-guide F with its front side ilfl'inem ith said rear wireguide. The barrel is PIQVIdEd fiIT its eyhndrical surface with an, J-IIHUlQY'SQIIQS ofgreogs" g which extend throughout its length and are arranged to register successively with said guide F so as to receive the front end of-the wire as it is fed forward by the feed rollers.

The front ends of these grooves may be flared to facilitate the entrance ofthe wire into the same, as shown in Fig. 2. The straight front end ofthe rotary barrel bears against the straight rear sideof the guideblock F and forms abutting edge which severs the wire at that point, after the advancing end of the wire has been fed into the mold. As shown in Fig. 4, the barrel turns in a'stationary supporting sleeve of bearing II which extends nearly throughout its length and is carried by brackets or standards I. I rising'from the frameA. An intermittent .rotary motion is imparted to the barrelfrom a rock-shaft J by an actuating pawl 7' carried by an,arm j secured to The ribs left between the longitudinal grooves of the barrel form teeth with which'the pawl 19' engages, as shownin Figs. 2 and 11. This pawl is held in engagement with the barrel by a spring 7' The shaft-J which is located on the rear side of the barre]. is rocked by a pair of tappets k connected with arotary crank-disk K by rigid arms 751 and arranged to trip alternately over opposite sides ofan actuating arm k of the said shaft, as shown in Figs. 1, 3 and 10. This crank-disk is secured to the lower end of an upright shaft L,which is driven by bevel gears Z, Z from the horizontal main shaft M of the machine. Retrograde movement of the barrel G is prevented by a detent pawl 12 attached to the rear end of the bearing H and engaging with the ribs of'the barrel, as shown in Figs. 4 and 5.

The bearing H isprovlded at its front side with a longitudinal discharge-passage or aperture 0 for the severed wires, which passage extends from end to end of the hearing, as shown in Figs. 1 and 4:. In order to insure the dischargeof the wires from the grooves of thebarrel upon arriving opposite the passage 0, the barrel is provided at suitable intervals with circumferential into which extend strippers or These strippers bear against the bottom of said annular grooves and their inner ends are beveled, as shown in Fig. 6,

groove-s 2) so that the wires are deflected or wedged out of the grooves upon encountering the inclined ends of the strippers and discharged through the passage 0. One of these strippersis also preferably located at the rear end of the barrel outside. of its bearing, as shown at p in Figs. 4:, 5 and 8.

By employing a series of strippers arranged in alinement at the fron side of the barrel G, as shown. the severed lengths of wire are discharged laterally in a straight and even manner. preventing bending of the same and permitting the seals with the attached wires to be closely and neatly packed.

The strippers also serve,to prevent endwise displacement of. the barrel in its bearing.

\Vhen the cutting edge of thebarrel becomes dull. the same is readily sharpened by grinding off its front end. As this opera- .tion shortens the barrel, its bearing H is made endwise adjustable in any suitable manner, so that it can be shifted toward'the guide-block F to compensate for the stock removed b grinding its end. In the construction s iown in the drawings, Figs. 5 and 6, the rear portion of said bearing is adjustably supported in the bifurcated upper end of the rear standard I by set screws (1- arranged in the jaws of the standard, while the front standard I of the bearing is carried by the free end of an arm or bracket q secured to the stationary'frame. The bearing H provided with a rearwardly ex tending stein (f which is clamped-in the bifurcated upper end of the standard I by a bolt Q3 so'tthat upon loosening this bolt the stem and the bearing carried by the same can be adjustedbackward or forward as required.

- The feed-rollers D are rotated intermittently, and when the invention is embodied in a seal-casting or similar machine, their motion is so timed that they feed the wire forward into the mold during the interval that the latter is open, and remain at rest while the seal is being cast Any suitable driving mechanism may be employed for effecting this movement of the feed-rollers.

The mechanism shown inthe drawings is constructed as follows: As shown in Fig. 3, the -feed-rollers are geared together by intermeshing spur gears 1', 1' of uniform diameter secured to their shafts, respectively,

and one of these shafts carries a gear pinion 'r which meshes with a large gear wheel R'nionnted loosely on a vertical shaft or arbor r. This large gear wheel is rotated intermittently for a quarter turn at a time, by an oscillating lever S one arm of which carries a spring bolt or catch 8 of suitable construction arranged, to interlock succeswhich cause said wheel to turn forward with i the grooved barrel G with its cooperating parts performs the three-fold function of a the lever, but allow the catch to leave the notches and ride idly over the wheel during the, return stroke of the lever. This lever oscillates upon the shaft 1 and is actuated from the crank-disk Kby a. connecting rod t, as seen in Figs. 1 and 3. The throw of this disk corresponds to the distance between adjacent notches of the gear wheel R.

The operation of the-machine is as follows: The feed rollers D and the guide and cutter-barrel G are rotated intermittently by the mechanism hereinbefore described, but are timed to operate alternately. end of the continuous wire being inserted in the front guide tube E, the same is fed forward. through the rear guide block 1* and into that guide groove 9 of the barrel which for the time being registers with said rear block. This groove directs the advancing end of the wire into the mold B, which latter then receives a charge of molten metal, thus casting a seal upon the end of the wire, as more fully described in the application for patent hereinbefore referred to. After the seal has been cast, the'barrel G turns the distance from one of its guide grooves to the next, thereby cutting off the wire at the rear edge of theguide block I? and bringing the next groove of the barrel into register with the guide-eye of said block. The movements of the wire feeder and the barrel are so timed that they both remain at rest while the seal is being cast and so that the barrel turned to sever the wire immediately after the casting operation. During the rotation of the barrel,'thc severed wire encounters the beveled ends of the strippers p 72 and i the wire with the attached seal is discharged through the side aperture or passage 0 of the bearing II.

From the foregoing it will be seen that positive guide for the wire'between the feed rollers and the mold or other element, a

wire-cutter, and a discharge device for the severed wires.

Vhile I have herein shown and described the improvement as applied to a seal-making machine, the same is not confined to that particular use, but is applicable to or useful in connection with various other machines for producing articles partly or wholly of wire.
