8 Claims. (Cl. -100) This invention relates to the art of comb making, and deals more particularly with the making of these combs which are commonly employed in the textile industry for mending purposes, and for the removal of weaving knots and wrong ends from the cloth.

A comb of this type ordinarily comprises a comb head, usually of steel or other metal, from which extend the pins constituting the teeth of the comb, the teeth being relatively close together, it being common practice to employ a comb having about twenty teeth to the inch. At the present time these combs are made by a process which involves the use of a helical wire spring as a means for properly spacing the teeth. Due to the fact that any diametrically opposite points of a single turn of the helical spring lie in a plane which is not perpendicular to the axis of the spring the pins are not positioned correctly in the comb head and with respect to one another. Very often it becomes necessary to exert tension on the spring to correct this difiiculty, and this results in a more or less uneven positioning of the pins. Inasmuch as the pins are ordinarily anchored in the head of the comb by soldering process, certain disadvantageous features reside in the present day methods employed.

With the foregoing in mind, this invention has in view as its primary object the provision of a process for making combs of the character described, which includes a step of positively correcting any distortion in the positioning of the pins, which may arise due to the helical formation of the spring.

A more detailed objective is the provision of a process which includes the step of positioning a second helical spring that is wound in a direction opposite to that of the first spring over the pins to correct distortion in the positioning effects attending the use of the first spring.

A further object of the invention is to provide in a process of the character noted the step of accurately aligning the helical spring which is used for spacing purposes. This invention contemplates the use of filling members which are inserted in the spring on each side of the pins to render rigid the spring construction.

Another object of the invention is the provision of a process for making textile combs which includes the step of soldering the pins in the comb head without distempering to any material extent the steel pins.

With the above objects in View the present invention comprises a process for making textile combs which consists in first placing the large ends of the comb pins between two bars designed to constitute the head of the comb, and clamping the parts together. This spring is aligned by inserting two fiat wires therein, one on each side of the pins, and then inserting two half round wires, one on each side of the flat wires. These flat and half-round wires, together with the pins, substantially fill the spring.

A second spring complemental to the first and wound is a direction opposite to that in which the first spring is wound, is now forced over the small ends of the pins, and this latter spring may also be aligned by the insertion of the wires. A Wooden clamp is now positioned on the pins intermediate the head of the comb and the first positioned spring. The wooden clamp is now treated with soap and lime and later dipped in lime water and then inserted in a solder bath. The comb is now finished in the usual manner and cut into any desired lengths.

For a full and more complete understanding of the invention, reference may be had to the following description and accompanying drawing wherein:

Figure 1 is a perspective view bringing out the arrangement of the pins in the two bars of the comb head at the beginning of the process,

Figure 2 is a section through the comb head, showing the pins with the spacing spring positioned thereover,

Figure 3 is a view similar to Figure 2, but showing further the insertion of the fiat wires, while Figure 4 is another view similar to Figures 2 and 3, showing all the flattened and half-round bars inserted,

Figure 5 is a front elevation of a portion of the comb With the first spacing spring positioned over the pins and aligned by the wires,

Figure 6 is a view similar to Figure 5 showing both spacing springs in operative position,

Figure '7 is a section through the comb assembly shown at Figure 6; this view is taken about on the line 1-1 of Figure 6, and

Figure 8 is a front elevational illustration of the application of the wooden clamp.

Referring now to the drawing, wherein like reference characters denote corresponding parts, a process carried out in accordance with this invention may be described as including the step of first positioning a plurality of pins I 0 between a pair of bars H which are designed to constitute the head of the comb when the work is finished. The pins 10 are preferably of a high grade steel, having the points designated l2 and the large ends denoted at l3.- In the illustrated embodiment the bars II are of steel, and are held together by any suitable clamping means, such as the wire l4, having its ends twisted together as at l5.

The step of first positioning the pins l0 between the bars II with the large ends I3 therebetween is carried out by hand, no attempt being made at this point to accurately space the pins apart. A helical spring designated 16 is now forced over the pointed ends l2 of the pins In, there being one turn of the helix between adjacent pins.

The spring "5 is now aligned by inserting, first, substantially fiat wires I! in the spring on each side of the pins in, as clearly shown in Figure 3. Half-round wires l8 are then inserted on each side of the flat wires [1. It is noted that the curvature of the round faces of the halfround wires is substantially that of the inner contour of the spring 16, the latter, together with the wires I? and [8, now making up a substantially rigid construction which insures the accurate alignment of the spring I6.

In this condition it is notable that the pins II] are not positioned exactly perpendicular to the axis of the spring It due to the fact that no two diametrically opposite points of any one bend of the helix may lie in a plane perpendicular to this axis. In order to correct this condition and to insure an accurate spacing and alignment of the pins I0, I now force a second spring l9 over the small ends I2 of the pins It. This spring H) is complemental to the spring l6, that is, it is helical, but Wound in a direction opposite to that in which the spring I6 is wound. This spring I!) may be forced on the pins l0 until it contacts the spring l6, and it may be aligned in the same manner as was the spring H5.

The pins II! are now spaced not by the spring is alone, but by the springs l6 and is together, as is clearly brought out in Figures 6 and 7, and the pins will lie substantially perpendicular to the axes of the springs It and I9.

Referring now to Figure 8, a wooden clamp 20 is now positioned about the large ends l3 of the pins H) between the spring l6 and the bars I l The clamp may be of a simple construction, such as two pieces of wood held together by the wires shown at 2!.

The work is now ready to be soldered together in its finished state. Accordingly, that portion of the wooden clamp 20 which may be inserted in solder is treated with soap and lime so that it will not be affected by the solder, and it is allowed to become almost dry. The entire work, including the pins, clamp, head, etc., is now dipped in lime water and is then dipped in a solder bath, with the large ends l3 of the .pins, head H, and a portion of the Wooden clamp 20, being immersed therein. Just beforethis dipping in the solder bath, a final finishing of the pins to insure their accurate alignment may be carried out by the use of a fine brass tool. This is done to insure the evenness of the points l2 of the pins. By immersing only those parts of the pins which are to be affected by the solder, namely, the large ends in the manner noted, distemper of the steel of the pins is prevented.

After soldering, the final finishing steps, such as rubbing with a pumice stone dipped in kerosene, and polishing with lime chalk, may be carried out. The steel head Il may be cut at any desired place to provide combs of any desired length.

While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be understood that I am not to be limited to the exact steps illustrated and described because various modifications of these details may be provided in putting the invention in practice within the purview of the appended claims.
