Application January 31, 1938, Serial No. 187,955 4 Claims. This invention relates to an attachment for wooden braider bobbins whereby bobbins having worn ratchets can be used e?iciently with carriers of the ordinary latch or pawl type. It is well known to those skilled in the art that the ratchet teeth of wooden braider bobbins quickly become worn and rounded with the re sult that frequent stoppage occurs. An object of the present invention is to equip 10 the bottom or ratchet portion of a wooden braider bobbin with a toothed latch engaging member of metal or other suitable wear-resisting material, the teeth thereof being positioned to engage the latch instead of the wooden teeth of the bobbin 15 ratchet whereby it is possible to use worn braider bobbins at maximum braider speed without caus ing breakage of yarn or stoppage such as cause the bobbins to throw slack. V A still further object is to provide a braider bobbin attachment which, because of the elimi nation of all possibility of locking due to wear, permits a free, easy and regular tension on the yarn as it is unwound and enables the braiders to run at a speed which is well above what is 25 considered reasonable under ordinary practice. With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts herein 30 after more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts Without departing from the spirit of the invention as claimed. 35 In the accompanying drawing the preferred form of the invention has been shown. In said drawing— Figure 1 is a side elevation of a braiding ma chine carrier showing the present improvements 40 applied to the worn ratchet of the bobbin. Figure 2 is an elevation of the structure shown in Figure l as viewed from the left of said ?gure. Figure 3 is a plan view with the bottom re moved. 45 ‘ Figure 4 is a central vertical section through the reclaiming attachment constituting the pres ent invention. Referring to the ?gures by characters of refer ence A constitutes the base portion of a carrier 50 provided with a spindle B adapted to engage and support a package which can be in the form of a bobbin C formed of wood and provided with the usual ratchet teeth D at the bottom thereof. In the structure illustrated the carrier includes a 55 pawl E having a tooth F adapted to move into (01. 96-45) and out of the spaces between the ratchet teeth. This pawl is connected to a wire G having a loop H which is slidable on a standard I projecting upwardly from the base A. A weight J is slid able on the standard and, under normal working conditions, is supported by the leading thread K extending from the package and which thread is extended through the standard and upwardly therefrom. Thus the weight J normally is held elevated against loop H so as to support the pawl E out of normal position with the tooth F dis engaged from the ratchet. The pawl is thus maintained under normal working conditions but, should the thread become slack from any cause, the weight J will descend by gravity as shown in 15 Figure 1, thereby releasing loop H and allowing the tooth of the pawl to move upwardly into po sition between two of the teeth of the ratchet on the bobbin. The structure thus far described constitutes no part of the present invention but is in general use. While it results in ef?cient operation as long as the teeth of the ratchet on the braider bobbin are not worn, it has been found that as these teeth wear due to contact with the pawl, the e?i ciency of the braider bobbin is lessened until ultimately it becomes necessary to discard the bobbin due to the resultant frequent stoppage. As before stated the present invention is de signed to permit e?icient use of the worn braider 30 bobbin and in the drawing the attachment con stituting this invention has been shown combined with the worn ratchet teeth of a bobbin. This attachment is in the form of a central disk I having an opening 2 for the reception of the spindle B and from the periphery of the bobbin radiate wear-resisting teeth or liners 3 the side faces of which preferably diverge outwardly as shown particularly in Figure 3 while the top faces are slightly pitched as shown at 4 in Figure 4. These teeth are regularly spaced and are equal in number to the teeth of the ratchet. They are so located and shaped that, when the attache ment is assembled with the ratchet end of a braider bobbin, the wear teeth or liners will ?t within the respective recesses between the teeth D of the ratchet thereby presenting wear faces which will be abutted by the pawl as shown par ticularly in Figures 2 and 3. As these liners are applied to the worn faces of the ratchet teeth the 50 said faces are prevented from being engaged by the pawl and, consequently, the ratchet will, in effect, be a wooden one the teeth of which are faced with metal or other wear-resisting mate rial. However as these facings form integral 55 .2 2,117,126 . parts of the ring I and are readily renewable and can be quickly applied to a Worn braider bobbin, the attachments in their complete form are de signed to be sold to the trade as such for quick installation. Consequently a considerable sav ing is effected because of the fact that bobbins which heretofore have been discarded as un?t for use, can continue in service inde?nitely. Fur thermore, through the use of the reclaiming at 10 tachment it has been found, in practice, that it is possible to run the braiders at a speed well above that considered reasonable for braiding machines utilizing wooden bobbins without the attachment. What is claimed is: 15 1. As an article of manufacture, a reclaimer for wooden braider bobbins including an aper tured disk and regularly spaced radial liners pro portioned for engagement with the working faces 20 of ratchet teeth on a bobbin. 2. As an article of manufacture a reclaiming attachment for wooden braider bobbins having ratchet teeth, comprising spaced lining means proportioned for engagement with the working faces of the respective teeth of the ratchet and an integral connection between said means. 3. The combination with a braiding machine carrier including a spindle, a pawl, and pawl-ac tuating means, and a braider bobbin on the spin dle and having a ratchet, of means on the spin dle and interposed between the ratchet teeth and the pawl for transmitting thrust from said teeth to the pawl. 10 4. The combination with a braiding machine carrier including a spindle, a pawl, and pawl actuating means, and a braider bobbin on the spindle and having a ratchet, of means on the spindle and interposed between the ratchet teeth 15 and the pawl for transmitting thrust from said teeth to the pawl, said means including a spindle receiving portion and radial members integral with said portion and positioned and propor tioned for engagement with the working faces of 20 the respective teeth of the ratchet.
