mwuto v orrnn sa'r a CARRIER FOR BRAIDING-MAGHINES.

Application filed. November 23, 1916.

1 b all whom it may concern:

Be it known that I, GEORGE F. MCCAHEY, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Carriers for Braiding-Machines, of which the following is a specification.

This invention relates to an improvement in carriers for braiding machines, and the primary object of the invention is to provide a stop on the top of the standard to positively prevent the top weight or latch from being accidentally thrown from the standard even while the carrier is running at a high velocity.

A further object of the invention is to leave one side of the standard straight to its upper end and cut away on its opposite edge for a short distance downward from its upper end whereby this latch may be applied to the standard at a point below the upper stop lug by a laterally rotating motion.

The invention further consists in the provision of a bottom or tension weight also slidable on the standard provided with a finger or extension for engaging a portion of the top latch to prevent the latter from rotating on the standard when both are in raised position.

It is found in practice that where the top latch is passed onto the standard over the end thereof, that the short laterally extending boss must be so small that it fails to serve as a positive stop to prevent the latch from being thrown off therefrom in the same direction it was applied, thereby eliminating the traveling speed of the carrier.

To obviate this serious difiiculty and prevent the latch from being thrown upward off the end of the standard, I have cut away the side of the standard to permit this latch to be passed onto the standard by alateral rotary motion and then I provide means on the bottom or tension weight for preventing the latch from rotating on the standard when in raised position.

A further advantage of my improved construction is that the latch is provided with a continuous or unbroken bearing on the yarn on the spool, the cut away portion of the standard being on the opposite side or the side which does not receive the strain.

With these and other objects in view, the invention consists of certain novel features Specification of Letters Patent.

of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation showing my improved standard with a spool mounted on the spindle and the tension weight and latch mounted on the standard, the weight being in the down position.

Fig. 2 illustrates the bottom weight as having been raised to engage and raise the latch, also showing the finger on the tension weight engaging the boss on the latch to prevent the latter from rotating while in raised position.

Fig. 3 is a view of the rear side of the standard showing the one edge cut-away, and representing the latch in dotted lines as being applied to the standard.

Fig. is a rear view of the latch showing the lateral extension thereof designed to be engaged by the projection on the bottom weight to prevent rotation of the latch.

Fig. 5 is a plan view showing the stand ard in section on line H of Fig. 2 through the reduced portion thereof, also representing the latch in the act of being applied to the standard at its reduced point by a lat eral rotating motion, the end of the spool also being shown.

Fig. 6 is a rear view of the bottom or yarn tension weight.

Referring to the drawings, 10 designates the carrier frame having a groove 11 adapted to be run and be guided in the usual raceway, said carrier frame being also provided with a spindle 12 on which a yarn spool 13 is mounted. The upper end or head of the spool 14 is provided with the usual ratchet teeth 15.

This carrier frame is provided with a standard 16 having the usual lead eve 1'. in its upper end and a guide eye 18 near its middle portion. The standard is also provided with an exceptionally large forwai'dly projecting stop or lug 19 at its upper en Another feature in the construction of the standard is that it is provided with one straight edge 20 extending up to this guide eye and lip while its opposite edge at 21. see Figs. 3 and 5, is cut awav for a short distance downward to provide a narrow neck portion for the purpose of permitting the tension weight 22 and also the latch 93 to be positioned thereonto.

An essential feature of my invention is that the stop lip 19 is formed of asi/ie so large that the latch cannot be passed tlrei'eover onto the standard for the reason that when the carrier is running a high we of speed the tension weight is thrown with great force against the latch which drii es it hard against this stop", and great tronlzile has been experienced with the old style carrier, where the latch is applied over the end of the standard in throwing the latch over the lip, in which case the latch is so long in returning that'it permits the spool to rotate several teeth and so allows the bottom weight to drop sufficiently to engage the stop lever an'dst'op the machine, but my improved construction this stop lug so large that it must positively engage and limit the upward motion of this latch. Therefore in order that so large and positive a stop may be used, I am obliged to apply the latch to the standard at a point below the top, which is accomplished by hooking one edge 23 of the latch around the straight edge of the standard as illustrated in Fig. 5 and then to swing the opposite edge 2-.t around through the cut-away portion of the standard after which it is permitted to slide down the standard into position to permit its tongue 25 to engage the ratchet teeth 15 on the spool.

In order to positively prevent this latch from rotating back again in the direction to release itself while running, I have formed a laterally extending boss 26011 one edge thereof and I have also provided a finger or upwardly extending member27, on the upper end of the tension weight 22, which finger is adapted to hook over or around the boss 26 when the weight is raised so as to positively prevent rotation of this latch when in raised position as illustrated in Fig. 2.

I have shown and described one means by which this top latch may be prevented from rotating while in its up position but there are many ways ofaccomplishing this object and any suitable means may be employed for this purpose for preventing such rotating motion.

Another feature which is of importance is that the straight side edge of the standard produces a full length bearing for the working edge of the latch, even when thrown upward and out of engagement with the spool.

This is not the case with the usual standard which is cut away on both of its edges.

Having thus described one illustrative embodiment of my invention I desire it to be understood that I do not wish to limit my self to the exact construction shown L11Cl described as the details may be changed (,epies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

without departing from the spirit of my invention, the scope of which is defined by the appended claims. 5

I claim:

I I. A braider carrier comprising a f"ame having a standard with longitudinally-chsposed guiding edges, a yarn tension weight slidabl'e on said standard, a latch having grooved edges with guiding flanges to slidably engage the guiding edges of said st andard, a head on the free end of said standard of a size to prevent the passage of thel'atch there'over, a section of one edge of said standard inmiedi'ately below said head being remoi 'ed substantially equal to the length of said guide hinge on the corresponding edge of the latch whereby said latch may be cons nect'ed t'o an'd'disconnected from said stand ard by a rotating mot-ion only, and means for preventing accidental disengagement of 7 said latch from said standard when carried upward by said tension weight.

A carrier. for braid 1g machines comprising a frame having a spool spindleand a standard, a sliding latch on said standard for engaging teeth 'on the spool, a lateral extension on theobody of said latch, a yarn tension weight also slidable on said standard, a stop lug on the standard of a size to prevent the latch being removed over the-eml thereof, one edge of said standard being straight to provide a bearing for the latch to the top of its stroke, said standard being reduced on its opposite edge to permit the latch to be app-lied thereto at a point below said stop with a rotating motion, and an upward extension on one edge of said weight. to engage said lateral-extension on the latch to prevent an unlocking rotativ'e movement of the latter when both are raised.

3. A carrier for braiding machines comprising a frame having a spool spindle and a standard, a sliding latch on said standard for engaging said spool, a yarn tension weight also slidable on said standard, a stop at theend of said standard to prevent the latch from being thrown or otherwise removed thereover, one edge e: said standard being straight and its opposite edge cut away at a point just below said stop to permit ready application of the latch to the stand- In testimony whereof I ailix my signature in presence of a witness.
