MACHINE FOR STRINGING BEADS.

. SPECIFICATION forming part of Letters Patent No. 244,452, dated July 19, 1881. .Application filed May 31, 1881. (No model.) Patented in Germany August 20, 1880.

To all whom it may concern Beit known that I, WILHELM HALSTEN- BAOH, residing at the city of Barmeu, in the Kingdom of Prussia, in the German Empire, have invented Improvements in Machines for Stringing Glass Beads, of which the following is a specification.

The object of this invention is to string glass beads on strings of any kind and to secure them at regular intervals thereon. For this purpose it is necessary to first string the beads, and then to shift them by suitable mechanism to points on the strings which have been provided immediately before the shifting of the beads with some adhesive or cementing substance. The machine is constructed in sucha mannerthatsimultaneouslyfiftyormorestrings can be supplied with beads.

The invention consists, first, of a preparatory machine for stringing the beads and, secondly, of a machine by-which the stringed heads are shifted to proper distances from each other and secured to the strings by means of a suitable cement or pasting substance.

In the accompanying drawings, Figure 1 represents a side view,and Fig. 2 aplauview, of amachine for stringingthebeads; and Figs. 3 and 4 represent respectively a plan view, partly in section, and a side elevation of a machine for arranging the beads'equidistantly on i the strings and cementing them thereto; and Figs. 5 and 6 are a detail view and a vertical transverse section of a modified portion of the machine for arranging the heads at proper distances.

Similar letters of reference indicate, corresponding parts.

The stringing of the beads is accomplished by means of the preparatory machine shown in Figs. 1 and 2, which consists of a table A, upon which are arranged a number of p transverse slats,B, that carry as many vertical pins as there are strings to be beaded. In bearings supported on brackets at opposite ends of the frame A are supported two roller-beams,

A A, while above them are supported in similar bracket-bearin gs the guide-rolls D D, over which the strings are conducted after having been secured to the roller-beams A A The stringing of the beads is accomplished in the following manner: All the strings are first wound upon one of the roller-beams A or A and the beads are then strung upon the ends of the strings, as many as can find room between the slats on the table A. I All the strings are-now attached to the opposite roller-beam and wound up thereon by means of a hand crank secured to one end of the same. The beads are thereby subdivided into groups, and retained by means of the pins of the slats B, while the strings are drawn nearly entirely through the beads. As the slats are arranged at a distance of from ten to twelve centimeters from each other, and as the beads are subdivided in groups of the same length, each group being retained by a pin, it is possible to draw the strings through a row of beads of about two meters in length, while without the subdivision and retention of the heads the strings would be broken by the tension exerted even by a shortrow of beadssay of about twenty centimeters in length. When thebeads are strung they are close to each other, so that they can be afterward arranged'at regular distances from each other by a separate machine, to be hereinafter described.

Itis obvious that when unwinding the strings from the roller-beam A a sufficient length of string must remain thereon so as to provide room for the sum of the distances at which the beads are to be arranged afterward. As soon as this is accomplished the groups of beads which are retained between the slats are lifted from the same and the strings wound up with the beadsuponthefirstroller-beam,A,untilthe entire lengthis unwound from the roller-beamA The ends of the strings are detached from the beam A and a new series of beads strung thereon, which are again placed sidewise of the pins of the slats B, after which the strings are again attached to the roller-beam A and drawn by the turning of the same through the beads to a distance corresponding to the sum of the distances between the beads. The strings are then again unwound from the roller-beam A wound upon beam A, provided with beads, and so on until the proper number of beads has been strung. When the strings on the roller-beam A are supplied with the required quantity of beadsthey are removed from the preparatory machine and placed onto the machine which is specially devised for the proper securing of the heads at equal regular intervals from each other. This machineis adapted to support the roller-beams A A in brackets at one end, as shown in Figs. 3 and 4. The

machine is also arranged with transverse slats the purpose of taking up the groups of beads of a series and retaining them during the forward motion of the beads. Instead of being attached to the table, the transverse slats are applied to an endless apron or chain, which passes around the stretching-rolls B B The loose beads are retained upon the strings by means of a metallic guard-comb, O, which is attached to the ends of a lever-frame, C, that is pivoted to side standards of the supportingframe of the machine. The first beads of the strings form in this position contact with an inclined bridge, G, below the strings.

The lever-frame O rests by vertical stays upon cams of a main shaft, H, and is lifted with the comb O at each revolution of the cams at the moment when the first head has to be shifted in forward direction. This is done by a second comb, D,which is vertically movable in slots of side standards, E, of a carriage, E. The carriage E receives its motion by drivingrods F from cranks Z, attached to the outer ends of the cam-shaft H. When the carriage has been moved forward far enough so that the comb D has arrived between the first and second row of beads-that is to say, closely before the inclined bridge' Gthe comb D is lifted by the pivot-levers G, the free ends of which are actuated by cams upon the shaft H. The comb D engages thereby the first transverse row of beads, while the comb (J is simultaneously lifted above the same, so as to admit the forward motion of the transverse row of heads toward acomb, T. The instant when the first row of beads has been carried in front of the guard-comb C it is dropped again, so as to retain the next row of beads, and to resume, consequently, the position shown in the drawin gs in Fig.3. Before the shifting of the beads on the strings can take place the strings are respectively connected to the reels L L L. (Shown clearly in Figs. 3 and 4 of the drawings.) The comb D is supported in raised position by the levers G until the shifting of the beads for the required distance is completed. During the shifting of the heads the strings are provided with paste or cement by the comb T, which is connected to the ends of two levers, t, the paste or cement being taken up by the comb T from a trough, T. The motion of the comb T is imparted by fulcrumed levers T the ends of which are acted upon by rollers or pins N projecting from cams of the main shaft H. The strings are supplied with paste or cement exactly at the points where the beads have been shifted by the comb D, so that they are secured accurately at the required points. The paste or cement may be colored so as to correspond to the color of the beads.

The carriage E is connected by a rod, K, with the oscillating crank K of a transverse rock-shaft, K the crank K being provided with a pawl for engaging a ratchet-wheel of the shaft K which is connected by a pulleyand-belt transmission with the reels L L' L so as to impart intermittent rotary motion to the same after each row of heads is secured.

The forward motion of the endless apron B is produced by a pawl-and-ratchet mechanism, 13, which is placed either upon a separate roller that is connected by an actuating-cord with the roller B or directly upon the roller B so that the apron is moved forward forthe thickness of one bead. When all the beads of one series are pasted onto the strings the endless apron B is returned into the position shown in the drawings and belayed with a new series of beads.

From the description it is obvious that the heads have to be strung in sets or series, and in such a manner that the unstrung portion between two series of beads is equal to the sum of the distances between the beads of a series after they are shifted. According to this the stringing of the beads has to be computed.

In place of the endless apron B a series of rolls, W, may be used, which are provided with three, four, or more radially-arranged combs, X, for the proper separating of the beads on the strings, as shown in the detail Figs. 5 and 6.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The method of making beaded strings which consists in shifting the beads on their strings to regular distances from each other and securing the beads thereto by paste or cement, substantially as described.

2. In a machine for stringing glass beads, a series of transverse equidistant slats having projecting pins or forks for the retention of a group of beads, substantially as specified.

3. Inamachiuetbrfastening beads on strings at regular intervals, an intermittent oscillating comb, O, to retain and release the beads, as set forth.

4. Ina machine for fastening beads on strings at regular intervals, a comb, D, supported on a reciprocating carriage, and mechanism for shifting the beads on the strings with the comb, as described.

5. In amachinefor fastening beads on strings at regular intervals, a forked oscillating comb, T, in combination with a trough, T, and mechanism, substantially as described, for taking upjhe paste or cement and transferring it to the strings at proper intervals, substantially as set forth.

6. Inamachine for fastening beads on strings at regular intervals, the combination, with the oscillating retaining-comb G and an inclined bridge, G of an intermittently-reciprocating comb, D, and an oscillating comb, T, for supplying paste to the strings, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
