CARRIER FOR BRAIDING AND SIMILAR MACHINES.

Specification of Letters Patent.

Application filed July 15, 1907.

Patented Feb. 14, 1911. Serial No. 383,717.

T 0 all whom it may concern:

Be it known that I, ANKER PETERSEN, a

subject of the King of Denmark, but at present a resident of Chelsea, in the county of Suifolkand State of Massachusetts, have invented an Improvement in Carriers for Braiding and Similar Machines, of which the following description, in connection with the accompanying drawing, is a specifica tion, like letters on the drawing representing like parts.

This invention relates to braiding machine carriers and has for its object to provide a carrier which is capable of sustaining a very much larger thread mass than is commonly used in braiding machine carriers, and which does not make use of the dangling weights which are commonly employed in connection with the let-off mechanism of such carriers. By dispensing with these weights and the parts for guiding the same,

the total weight of the carrier is very much reduced, thus permitting the carrier to be run in the braiding machine at a very much higher rate of speed.

The novel features wherein my invention resides will be hereinafter described and will then be pointed out in the appended claims.

Figure 1 in side elevation represents a carrier for a braiding machine, the same being represented as provided with the improvements made the subject of claims in this application, a portion of the bars B, B being broken away; Fig. 2 is a top or plan view of the carrier, the full lines showing the arms of the take-up and pulleff in operative position, the dotted lines showing the same in their normal positions, the position they will occupy under the control of their springs; Fig. 8 shows the arms substantially in the position they will occupy preparatory to the release of the pawl forming part of the let-otf5 Fig. 4 is a section below the dotted line 4, Fig. 1. and Fig. 5 is a section in the line 55, Fig. 4:, below plate 5.

The carrier shown has a base comprising a bottom plate A and a foot A connected by a neck A that travels through the usual cross grooves of the braiding machine, the foot having a stud A shaped to be embraced by the notched driving arms or gears such as are usually employed in braiding machines as now made, for moving the carriers about in the carrier grooves. The bottom plate A has connected with and rising therefrom suitable bars B, B that in turn are connected at their upper ends with and sustain a top plate B. The top plate has a central hole to receive the upper end of a spindle a, the lower end a of which, see dotted lines Fig. 4, enters a hole a see Fig. 5, made in a step a mounted on the upper side of the bottom plate. The spindle a at a short distance from its lower end. is provided with a plate 7) shown as having a series of shoulders b and notches b and the spindle immediately above said plate, which is made as a ratchet toothed wheel, is provided with a portion 6 other than round, said portion being preferably of the shape shown in Fig. 4, to be engaged by a notch made in the lower end of a small quill 2 preferably of wood, the upper end of which is shown just above the thread mass 0 wound on said quill. The quill may be, in practice, about one-quarter of an inch in diameter, and the thread mass one and threequarters of an inch, and preferably the thread mass will be wound either on a Leeson winding machine, or in some other usual way to retain the thread in such form as to insure uniform unwinding.

On the top side of the bottom plate I pivot a pawl (Z, using a screw cZ. Said pawl has a shoulder which is acted upon normally by a spring (Z connected with the bottom plate, and the end of the pawl is provided with an upturned lug 3 which is adapted to enter one of a plurality of notches 6 formed in the plate 6. Said plate is also provided with shoulders Z2 which form continuations of one side of the notches. This pawl (Z forms part of a let-off mechanism which normally locks the spindle and thread mass from turning but which is released from the spindle by an increased tension on the thread. When the pawl occupies the position shown in Fig. 1, it obviously will lock the plate I) and the spindle from turning. To effect the release of the pawl from the plate I) when it is desired to let off more thread. from the thread mass, I have provided the carrier with a rod or shaft (Z which is journaled in the top and bottom plates respectively, and which has at its lower end an arm (Z adapted to engage a projection 12 carried by the pawl (Z. The shaft (Z is acted on normally by a spring d which tends to turn the shaft in a direction to bring the arm (Z into the position shown in Fig. l, that is, against one of the bars B. To accomplish this the spring d may conveniently have its lower end fastened to the shaft (Z while its upper end is bent to contact with the bar B. The portion of the rod or shaft (5 above the upper plate B is extended horizontally to form a let-off arm a at the end of which is provided an eye 6 This eye is arranged to have the thread passed therethrough as will be presently described, and when the tension on the thread is sufficient, the arm 0 which normally occupies the dotted line position Fig. 2, is swung around into the position shown in full lines Figs. 2 and 3, and thus turns the shaft (Z thereby bringing the arm 0? against the shoulder 12 and withdrawing the pawl from the notch in the plate Z).

The take-up mechanism herein shown is in the form of a take-up arm 6 having an eye 0 at its end, which arm is sustained by a rod or shaft 6 that is journaled in the top and bottom plates B A. The rod or shaft 6 is surrounded by a spiral spring f, one end of which is made fast to the shaft by any suitable means, and the other end of which is bent laterally to abut. against the bar 13. The take-up arm e is arranged to stand at substantially right angles to the shaft 0'' and also stands parallel with the top plate 13. The spring f tends normally to turn the shaft 6 into a position to carry the take-up arm 0- into the dotted line position Fig. 2. The arm 6- is provided with an eye 6 in line with the axis of its movement. Said eye may conveniently be formed by bending the wire constituting the shaft 6 into proper shape to make the eye. The shaft 6' is shown as having extending therefrom a projection f, which projection may conveniently be the end of the spring f which. surrounds said shaft. This projection f is adapted to co-act with the bar B to act as a. stop for limiting the swinging movement of the take-up arm in one direction.

The top plate 6 has extending therefrom an arm presenting at its end a delivery eye 9 and this eye is preferably made S-shaped so as to present two thread passages, as clearly seen in Fig. 1. The bar B is also provided with a thread guide g. \Vhen the carrier is properly threaded up and is in operation, the thread from the thread mass 0 is led through the thread guide g, thence into the lower passage of the delivery eye g, thence into the eye 6 of the let-off arm, thence around a pulley 0 which is rotatably sustained on the shaft (Z thence through the eye 6 and through the eye 6 at the end of the take-up arm, and thence through the upper thread passage of the delivery eye to the cloth. lVhen the thread is entirely free from tension. the take-up arm a and the letotf arm 6 will occupy the dotted line positions Fig. 2, but as the thread is subjected to more or less tension, the take-up arm 0 is first drawn into the full line position Fig. 2 until it abuts against the delivery eye g as a stop, and at the same time the let-off arm is drawn from the dotted line position toward the delivery eye. lVhen the tension increases sufficiently to turn the let-offarm into the position shown in Fig. 3, the pawl cl will be released from the disk I) and the spindle with its thread mass will be allowed to turn, thus giving up some thread. As soon as the thread is given up, the spring (Z tends to move the let-off arm into the position shown in Fig. 2, thus carrying the arm (Z out of contact with the pawl and permitting the pawl to be brought up against the next shoulder I), thus locking again the spindle and thread mass. 7

It will be observed that both the let-off arm and the take-up arm operate in planes parallel with the plate 7) or in planes perpendicular to the thread mass. The advan-' tage of this construction is that neither the take-up arm nor the let-off arm take up any appreciable amount of room and the presence of neither one of these arms increases to any extent the size of the carrier. My invention also has the advantage that the takeup and let-off arms can be made comparatively light in weight and thus a braiding carrier capable of carrying a large quantity of thread mass can be provided without making the braiding carrier so heavy that it cannot be run rapidly in the braiding machine.

Another advantage which is secured by my improved construction is that derived from the fact that the thread passes around the pivotal point or axis of both the take-up arm and the let-off arm. By carrying the thread through the eye 6 of the take-up arm, it will be seen that any movement of said take-up arm will not produce any slack in or affect the thread between the eye 6 and the roll 6, such movement of the take-up arm affecting only the thread between the eye 0 and the delivery eye 9. Similarly the movement of the let-off arm does not affect the thread between the roll a and the take-up arm, but only affects the thread between the eye o and the eye 9. The result of this construction is that the two arms will accom- -plish their desired objects without interfering with each other.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a braiding carrier, the combination with a carrier frame comprising rigidly-connected top and bottom plates, of means to sustain a thread mass between said plates, a 7
