1 Claim. 1
This invention relates to a sinker head of the type used in flat, or full fashioned hosiery knitting machines.
One object of the invention is to produce an improved sinker head of th'e type set forth.
A sinker head of the type under consideration is provided with apertured lugs, by means of which it is secured to the bedplate or frame of the machine and with end, pendant bearing members in which the trunnions of the knock-over bit are journaled. The pendant bearing members referred to have thus far been formed as integral parts of the sinker head. This increased the dimculty of accurately machining the head and, if either the head or the bearing member wore out or suffered damage, it was necessary to discard the entire sinker head.
It is, therefore, a further object of this invention to produce an improved sinker head in which the bearing members referred to are made separate from and are firmly but detachably secured to the sinker bar, thus facilitating machining and permitting replacement of the sinker head or the bearing members independently of one another.
These and other objects are attained by the invention as set forth in the following specification and the accompanying drawings, in which:
Fig. l is a perspective, composite or exploded view showing the various parts of a, sinker head embodying the invention;
Fig. 2 is an enlarged section on line 2-2 of Fig. l, with the parts all assembled;
Fig. 3 is a section on line 3--3 of Fig. l, with the parts all assembled; and
Fig. 4 is a section on line 4-4 of Fig. l, with the parts all assembled.
The sinker head illustrated includes a body portion l which is cut down in thickness as compared with the end portions Il, so as to provide a recess for receiving a detach'able insert bar I2 which has machined therein grooves I3 for guidingthe sinkers in their movement transversely of the bar. The bar may be secured to the sinker by any suitable means, such as countersunk screws, but it is preferred to solder or braze the insert bar to the sinker head. The sinker head is provided with end lugs which are provided with countersunk apertures I4 for the passage of screws by means of which the sinker head may be attached to the bedplate of the knitting machine.
In order to provide bearings for th'e trunnions of the knock-over bit, it has heretofore been the practice to form pendant bearing members which were integral with the end portions H of the sinker head. Such members were difficult to machine and also increased the difficulty in machining of the sinker head itself. According to this invention, the pendant bearing members are formed entirely separate from the sinker head. As shown, the undersides of the end portions of the sinker head are provided with recesses l5 which are adapted to receive pins I6 formed at the upper ends of the pendant bearing members il, each of which constitutes one-half of a complete bearing. Th'e other halves of the bearings are in the nature of separate members I8 which are adapted to be detachably secured to the halves I1 by means of screws I9 passing through apertures 20 in the halves l1 and I8, as shown in Fig. 2. The pins I6 are soldered or brazed in the recesses I5 so as to firmly secure the bearing members Il While permitting the same to be removed by th'e application of heat. By this means, the machining of the sinker head and of the bearing members is facilitated and if it is necessary to discard the sinker head or the bearing members, the bearing members can be readily disengaged from the sinker head. The separable insert bar l2 is machined separately and is provided with a pendant shoulder 2l extending th'e entire length of the bar and adapted to abut the edge 22 of the sinker head to locate the insert bar relative to the sinker head.
When it is desired to remove the bar insert IZ or the pendant bearing members I1, it is merely necessary to apply heat suicient to melt the metal which forms the bond between these parts and the sinker head.
What is claimed is:
A sinker head including end apertures therein for receiving fastening means for securing said head to the bedplate of a knitting machine, and an intermediate body portion of a reduced thickness, a separate bar secured by metal fusion to one face of said body portion and having grooves for guiding the sinkers of the knitting machine, there being apertures in said end portions, pendant bearing members for engaging the trunnions of a knock-over bit forming part of the knitting machine, and pins carried by said bearing members and secured by metal fusion in said recesses to secure said bearing members to said end portions.
