MACHINERY FOR MANUFACTURING WAXED TAPERS AND COATED STRlNGS.

:"JPECIFICATION forming part of Letters Patent No. 303,98 dated August 26, 1884-.

Application filed Ociohcr13, 1853. (X0 model.)

To aZZ whom it; may concern.-

Be it known that I, GEORGE W. CODDING- TON, of Middletown, Butler county, Ohio, have invented certain new and useful Improvements in Machinery for Manufacturing \Vaxed Tapers and Coated Strings, of which the following is a specification.

The object of my invention is to provide a machine which shall rapidly and chcaplypro ducc waxed strings or tapers for sealing fruit cans or for lighting purposes. It has special reference, however, in. the present instance to the manufacture of waxed strings for sealing fruit-cans.

Letters Patent No. 235,79, for method of sealing frnit-eans, were granted to G. F. Hun saker on December 28, 1880; but heretofore it has been very troublesome and quite X13611- sive to manuiacturc the waxed strings therein described; but my invention produces these.

strings very cheaply and rapidly.

Referring to the drawings forming part of this specification, Figure 1. is a front elevation of the machine. Fig. 2 is an elevation of one side of the same. Fig. 3 is a sectional elevation, looking toward the rear of the machine, all of that portion in front of the arrow 1 in Fig. 2 being removed. Fig. 4 is a plan view of the machine, that portion above the arrow 2 in Fig. 1 being removed. Fig. 5 is a sectional elevation taken at the liner .rof Fig. 4, and looking toward the left in said Fig. 6 is a plan view of the mechanismt'or cutting the strings to the desired length. Figs. 7 and 8 represent the mechanism for removing each cutting of strings. Fig. 9 represents the mechanism for counting and removing the strings from the machine.

The main frame of the machine consists of the posts A A, connected by appropriate sills, u, and headers c, framed together, the posts A at the front of the machine extending some distanceabovc the tops of the posts A at the rear. Near the bottom of this frame, between the sills a, is secured a pan or vat, B, inwhich the melted was with which the strings are to be coated is placed. This pan may be heated by any desired means which will prevent the wax in the pan from burning-as, for instance, by steam. The wax with which the strings are to be coated is preferably melted in any apfigure.

propriate vessel before being delivered to the pan B, and is then poured into the said pan B, and this pan being suitably heated, the wax is kept in a liquid state.

This machine may be so constructed that any desired number of strings Z1 maybe coated at once, the strings being drawn through the wax in the pan 3 in a. manner to be hereinafter described.

I prefer to so construct the machine that it will coat twenty strings at once, as this is a convenient number to handle, andIhaveillustrated in this application. a machine constructed to coat this number. These strings are each passed over or around a roller, B, journaled between the posts A, above the pan B, and down to the pan, at the rear side of which each string passes through a staple or hook, Z), and, passing forward to the front side of the pan,each string passes up through another staple or' hook, If. These staples or hooks in both sides of the pan are near its bottom, and the strings Z), as they are drawn through the pan, are thus kept submerged in the molten wax in the pan B. After pass ing through the hooks b the strings pass up to the top of the frame, where they pass over a roller or drum, 0, j onrnaled between the posts A, and, after passing over this drum G, the strings pass down between two guides or feedrollers,dZ,journaled near the top of the posts D, in front of theposts A. This drum or roller 0 is provided with grooves c, in which the strings I) lie as they pass over the drum, thus keeping them separated from each other until they have passed over the drum. A short distance below the drum G is a guidebar, 3, suitably connected to the posts A, which bar is provided with notches at, corresponding in number to the number of grooves o in the drum 0, one of the notches L being located directly below each groove 0, serving to guide the strings 1) into said grooves. These rollers d d are shorter than the drum 0, and consequently the strings I) as they approach these rollers must com-'crgc to pass between the rollers, and this convergence is effected by means of a series of pins, (it, in the front face of a cross head or bar, D, connecting the top ends of the posts D, between which pins the strings pass, as shown in Fig. 1. The rollers d d, at the points between which the strings I) pass, are covered with felt or other soft pliable material, and thus the wax, which has become hardened on the strings before reaching these rollers, is not cracked, as would be the case were the rollers not covered by a soft material.

Between the posts A, near the bottom of the machine, is journaled the main drivingshaft 0, which maybe caused to revolve in any suitable manner, either by hand, steam, or other power. On this shaft is keyed a beltpulley, 0 around which pulley passes a belt, D which passes around the feed-roller (I, so that when the shaft 0 is caused to revolve the feed-roller is also caused to revolve, and the strings I), passing between the rollers d d, are drawn down, and hence through the molten wax in the pan B. To assist in this movement of the strings b, one end of the drum 0 over which the strings pass is provided with a pulley, G", and a belt, (1, passes around this pulley and around a pulley, G, on the end of the driving-shaft O, and a revolution of the shaft thus causes the drum 0 to revolve. As the stringsb are drawn through the pan B, the melted wax therein adheres to the strings, and as they leave the pan they are drawn against the edge of a plate, E, and this plate, being adjustable by means of slots c and set-screws 6, may be moved toward or away from the strings, and thus more or less of the wax may be scraped off from the strings as they leave the pan.

It is necessary to employsome means for cooling the wax and hardening it on the strings, and this I accomplish by means of a revolving fan, E, secured to a shaft, E", journaled in the headers a. This fan is caused to revolve by appropriate mechanism from the driving-shaft C. I preferably employ a shaft, E, journaled to the posts A above the driving-shaft G. On the driving-shaft is apulley, e, and on the shaft E immediately above the pulley 0 is a smaller pulley, 0", and a belt, 6, passes around these pulleys.

On the shaft E is a large pulley, E, and on the fan-shaft E in a line with the pulley 13*, is a smaller pulley, E and around these latter pulleys passes a belt, 6. Thus when the driving-shaft is caused to revolve the fanshaft is caused to revolve at an increased rate of speed, and the wind from this revolving fan, blowing on the strings I) as they pass up from the fanB to the drum 0, cools and hardens the wax 011 the strings. In addition to this fan, if desired, a trough or bucket, F, may be placed above the drum 0 and kept supplied with water, which is allowed to drip on the strings as they pass over the drum. This drum 0 is covered with cloth, which is kept constantly moistened by water from the trough F, the preferred means for conveying the water from the trough to the drum being a strip of cloth, 5, one edge of which is in the trough, and the other edge resting on the drum. This strip 5 acts on the principle of a siphon, and keeps the cloth on the drum 0 moist, and the strings I) are thus drawn between two moistened surfaces, and are thus cooled and moistened. The strings b having been coated with wax, it now becomes desirable to cut them into proper lengths for use, and this I accomplish by the following mechanism:

To the posts D, below the rollers d and d, is secured a frame, F, one side of the frame being secured to across-piece, F secured to the posts A. The sides of this frame are provided (see Fig. 6) with guides or ways f, between which slides a cross-head, f, secured to asliding bar, f", and to the end of this sliding barf is also secured a knife, F, which projects beyond the cross-head f. At the side of the frame F, opposite to the crosshead f, is secured a block, F, against which the edge of the knife F strikes when it is thrown forward. At the front of this block +that is, at the side toward the knife F is a loop, f through which the strings I) pass after leaving the rollers d and d, which loop holds all of the strings in front of the knife.

On top of the sliding barf is secured a lag, I

f, against which rests one end-of a'springg G,

the otherend of which spring is secured to a cross-bar, G, connected to the posts A above the cross-piece F and the tendency of this spring is to constantly force the knife F toward the block F. The end of the sliding bar f opposite to the knife, is pivoted to the upper end of a lever, G", which lever is secured to a pivot-bar, G, which is pivoted in the posts A between the cross-pieces F and the drivingshaft 0. (See Fig. 3.) On the shaft 0 is secured a cain pulley, against which the lower end of the lever Gr rests, and this pulley g is provided with one or more notches or grooves, 9, into which the end of the lever Gr may drop when the pulley is turned to the proper position. XVhen the end of the lever is out of the notches g, the knife F is held away from the block F, as shown in Figs. 5 and 6; but as soon as the end'of the lever drops into one of the notches the spring G throws the knife forward against the block, and the strings against the block are thus out. As the strings are constantly descending through the loop f in front of the block F, the knife must not remain for any appreciable time against the block, as it would retard the progress of the strings, and to prevent this I provide two spring-buffers, g and the cross-headf is provided with the blocks 9 which strike against the buffers when the knife is thrown forward, and the buffers are compressed to let the knife come in contact with the block; but the knife is immediately thrown back again from the block.

The circumference of the feed-roller d is preferably equal to the length to which it is desired to cut the strings, so that each revolution of this roller will present the required IIO length to the knife, and the size of the campulley g and the location of the notches 91 therein are such that at each revolution of the roller d the knife will be thrown forward and the strings out. After being cut oft the strings fall through a guide-trough, H, into a tray, H, and after each cutting of strings are thus dropped into the tray l-l they are pushed from this tray by a follower, 71, into a box, It, (shown by dotted lines in 'Fig. 1,) in the tray H, be low the tray H.

The mechanism for pushing the strings from the tray H is shown in detail in Figs. 7 and 8. On the driving-shaft G is a pulley, H, around the periphery of which extends a canrridge, 7r. Below this pulley H is a lever, H, pivoted near one end to the sill or bar (1, below the driving-shalt C, and the end of this lever H, immediately below the pulley H, is provided with pins it, between which pins the cam-ridge h on the pulley 11 passes. The opposite end of the lever ll is connected to the follower h by a rod, it. As the shaft 0 and pulley H are revolved, the cam-ridge It, operating on the pins h, moves the end of the lever H" back and forth, and the follower h is thus moved forward and pushes the strings oit from the tray H. "he size of the pulley H and the shape of the canrridge It? are such that the follower h is pushed forward immediately after each cutting of strings has fallen into the tray H. \Vhcn a certain number of strings as, for instance, one hundred-have been thus pushed off from the tray it into the box h", it is desirable that the box he automatically pushed away from the tray H; and this I accomplish by the mechanism shown in Figs. 1, 2, and 9. At the side of the posts I) is another post, I, to the top end of which is connected an arm, J, extending toward the post D, and to the end of this arm is pivoted the top end of a le ver, K, the lower end of which lever is pivoted to a sliding bar, K, secured and capable of sliding between the bars is, secured to the posts 1) and I, below the tray H". Between the post I and the lever K is a spring, K, which may be asshown or in the form of a spiral spring, the tendency of which spring is to constantly press the lower end of the lever K away from the post I. To the sliding bar K is connected one end of a rod, 7.1, the other end of which is connected to a follower, 76-, in the tray H-. hen the lever K is pushed away from the post I, the follower 7; in the tray 1-1 lies at one side of said tray and under the edge ofthe tray H, and the box it is placed against this follower to receive the strings which are pushed off from the tray H. To the side of the post D, between it and the lever K, isjournaled a gearwhcel, L, on the face of which are one or more inclined planes, 2, which engage the lever K as the wheel is turned, thus moving the lever toward the post I and pushing the box h away from the edge of the tray H. The journal of the roller (2 extends beyond the post I), to which the wheel L is j ournaled, and on this end of the journal is keyed a spur-whcel, L, on one side of which are teeth or cogs Z, which engage with the cogs of the wheel L as the roller d is revolved. Every time the roller (1 is caused to revolve, the teeth I engage with the wheel L and cause it to turn a limited distance, regulated by the number of teeth Z on the spur-wheel L. The relative proportion between the number of teeth Z and the number of cogs on the wheel L is such that when the roller d has revolved the required number of times to fill the box h with cuttings of strings, in the manner above described, one

of the inclined planes Z will come in contact with the lever K, and through the connections of the latter the box it will be pushed away from the tray H, and when this inclined plane passes the lever K the spring K moves the lever again toward the post I), and the follower k is thus carried back to the side of the tray H This relative proportion between the number of teeth on the spur-wheel L and on the wheel L must always be preserved. For instance, in a machine by which twenty strings are coated at once the wheel L is preferably provided with one hundred teeth, and has two inclined planes Z on its face. The wheel L should then he provided with eight teeth, by which construction every revolution of the wheel L moves the wheel L the distance of ten feet, and it will therefore require five revolutions of the roller :1 to turn the wheel one-half around, and the wheel L, having two inclined planes l, operates on the lever K at each one-halt revolution. Five revolutions of the roller d cause five cuttings of finished strings to be cut oh, and there being twenty in each cutting, one hundred strings will be delivered to the box it before it is pushed away from the tray 11. It the wheel L has but one inclined plane Z, the number of teeth '1 on the wheel L must be doubled, or the number of teeth on the wheel L must be diminishcd one half.

From the above description it will be seen that at each revolution of the roller d one cut-. ting of strings is delivered into the box it, and at each five revolutions this box is pushed away to indicate that a certain definite number of strings haveheen delivered into the box.

By the aid of this machine these waxed strings may be'very rapidly and cheaply pro duced, and they will also be more perfect than the strings or tapers heretofore manufactured.

While I have described my invention as applicable for the manufacture of strings such as are specifically specified in said Patent No. 235,879, I do not limit the application of my apparatus and improvements to any specific form or kind of string, but claim the right of their application, in whole or in part, to any and every kind of coated string to which they or either of them can be applied.
